At Lenox Hill Hospital, her lung was again re-expanded, and Dr. Byron Patton, a thoracic surgeon, recommended a procedure known as pleurodesis, in which the lung is mechanically attached to the surrounding sack called the pleura, so that even if the lung developed another leak, it wouldn't collapse.

Pleuropneumonia is inflammation of the lungs and pleura, pleurisy being the inflammation of the pleura alone.
|
|
Fibrosis can affect one or both of the two layers of tissue forming the pleura—the visceral pleura adjacent to the lung and the parietal pleura adjacent to the ribcage. The term fibrothorax implies severe fibrosis affecting both the visceral and the outer (parietal) pleura, fusing the lung to the chest wall. The condition starts as an undrained pleural effusion. Over time, the undrained pleural effusion causes sustained inflammation of the pleura, which can then lead to deposition of fibrin in the pleura and the development of a fibrotic scar.

The pleural cavity also known as the pleural space, is the thin fluid-filled space between the two pulmonary pleurae (known as visceral and parietal) of each lung. A pleura is a serous membrane which folds back onto itself to form a two-layered membranous pleural sac. The outer pleura (parietal pleura) is attached to the chest wall, but is separated from it by the endothoracic fascia. The inner pleura (visceral pleura) covers the lungs and adjoining structures, including blood vessels, bronchi and nerves.
|
|
Each lung is covered by a double membrane, called the pleurae; each membrane is a pleura – the visceral pleura adheres to the surface of the lung and the parietal pleura attaches to the thoracic cavity. The pleurae of each lung are not connected in any way.
|
|
The parietal pleura is supplied by the intercostal nerves and the phrenic nerve. The costal pleura is innervated by the intercostal nerves. The diaphragmatic portion of the parietal pleura overlies the diaphragm and is innervated by the phrenic nerve in its central portion and by the intercostal nerves in its peripheral portion. The mediastinal portion of the parietal pleura forms the lateral wall of the mediastinum and is innervated by the phrenic nerve.
|
|
Pleurodesis is a medical procedure in which part of the pleural space is artificially obliterated. It involves the adhesion of the visceral and the costal pleura. The mediastinal pleura is spared.
|
|
Autopsy specimen showing a large clotted hemothorax filling the entire pleural cavity. The thoracic cavity is a chamber within the chest, containing the lungs, heart, and numerous major blood vessels. Thin sheets of tissue known as the pleural membranes or pleura line the chest and cover the lungs - the chest wall is lined by the parietal pleura, while the visceral pleura covers the outside of the lungs. The visceral and parietal pleura are normally separated by only a thin layer of fluid, forming the pleural cavity.
|
|
The parietal pleura is the outer membrane that attaches to and lines the inner surface of the thoracic cavity, covers the upper surface of the diaphragm and is reflected over structures within the middle of the thorax. It separates the pleural cavity from the mediastinum. The parietal pleura is differentiated into regions in line with the location in the thorax. The "cervical pleura" (or "cupula of pleura") is in the region of the cervical vertebrae extending beyond the apex of the lung and into the neck.
|
|
A small amount of pleura extends below the ribs in the CVAs.
|
|
Pleural fluid is secreted by the parietal layer of the pleura and reabsorbed by the lymphatics in the most dependent parts of the parietal pleura, primarily the diaphragmatic and mediastinal regions. Exudative pleural effusions occur when the pleura is damaged, e.g., by trauma, infection or malignancy, and transudative pleural effusions develop when there is either excessive production of pleural fluid or the resorption capacity is reduced.
|
|
The pulmonary pleurae (sing. pleura) are the two layers of the invaginated sac surrounding each lung and attaching to the thoracic cavity. The visceral pleura is the delicate membrane that covers the surface of each lung, and dips into the fissures between the lobes of the lung. The parietal pleura is the outer membrane which is attached to the inner surface of the thoracic cavity.
|
|
The "costal pleura" lines the inner surfaces of the ribs and the intercostal muscles and are separated from them by endothoracic fascia. An extension of the endothoracic fascia known as the suprapleural membrane covers the apex of each lung in a thickened layer of connective tissue. The "diaphragmatic pleura" lines the convex surface of the diaphragm. The "mediastinal pleura" attaches to the other organs in the mediastinum and forms the separating lateral wall.
|
|
The pleuron (pl. pleura, from Greek side, rib) is a lateral sclerite of thoracic segment of an insect between the tergum and the sternum. The terms pro-, meso- and metapleuron are used respectively for the pleura of the first, second and third thoracic segments.
|
|
The abdominal somites are smooth and their pleura are rounded. The sixth somite is about twice as long as the fifth, its pleura are triangular and bluntly pointed. The telson is 1.5 times as long as the sixth somite. The dorsal surface of the telson carries two pairs of spinules.
|
|
The abdominal somites are smooth. The first has the pleura large and rounded. The pleura of the second overlap both those of the first and third. The third somite is noticeable in that the posteromedian part is hood-like prolonged posteriorly and reaches beyond the middle of the fourth somite.
|
|
In rounded atelectasis (Folded lung or Blesovsky syndrome), an outer portion of the lung slowly collapses as a result of scarring and shrinkage of the membrane layers covering the lungs (pleura), which would show as visceral pleural thickening and entrapment of lung tissue. This produces a rounded appearance on x-ray that doctors may mistake for a tumor. Rounded atelectasis is usually a complication of asbestos-induced disease of the pleura, but it may also result from other types of chronic scarring and thickening of the pleura.

Unfortunately, Mando Dalianis did not manage to get the unit sent to Ikaria. Dimitris Dalianis used then instead of a large syringe, partly to puncture the pleura of patients and also suck out pus from the pleura. As tube, he used the sounds hose from his stethoscope. The situation in the sanatorium was very primitive.

The fourth somite has the pleura rounded, those of the fifth end in a bluntly rounded top. The sixth somite is approximately 1.5 times as long as the fifth, both its pleura and posterolateral angles are rounded. The telson is distinctly longer than the sixth abdominal somite. It is elongate triangular and has two pairs of dorsal spines.

Initially the intraembryonic coelom is one continuous space. During development this space partitions to form the pericardial, pleural and peritoneal cavities. The diaphragm and the paired pleuropericardial membranes separate the coelomic cavity into four parts. From the splanchnopleura (the visceral mesodermal layer) develops the visceral pleura and from the somatopleura (parietal mesodermal layer) develops the parietal pleura.

Interpleural block is a medical procedure in which a local anesthetic is injected into the thoracic cage between the parietal and visceral pleura.
|
|
This clot tends to stick the parietal and visceral pleura together and has the potential to lead to scarring within the pleura, which if extensive leads to the condition known as a fibrothorax. Following the initial loss of blood, a small hemothorax may irritate the pleura, causing additional fluid to seep out, leading to a bloodstained pleural effusion. Furthermore, as enzymes in the pleural fluid begin to break down the clot, the protein concentration of the pleural fluid increases. As a result, the osmotic pressure of the pleural cavity increases, causing fluid to leak into the pleural cavity from the surrounding tissues.

Kerley B lines in a patient with congestive heart failure. ;Kerley B lines :These are short parallel lines at the lung periphery. These lines represent interlobular septa, which are usually less than 1 cm in length and parallel to one another at right angles to the pleura. They are located peripherally in contact with the pleura, but are generally absent along fissural surfaces.
|
|
The condition only causes symptoms if the visceral pleura is affected. Although fibrothorax may not cause any symptoms, people affected by the disorder may report shortness of breath. Persistent, recurrent pleural effusions are a possible symptom, caused by the persistent cavity formed by the hardening pleura around the original fluid collection. Shortness of breath tends to develop gradually and may worsen over time.

The costomediastinal recess is a potential space at the border of the mediastinal pleura and the costal pleura. It assists lung expansion during deep inspiration, although its role is not as significant as the costodiaphragmatic recess, which has a greater volume. The lung expands into the costomediastinal recess even during shallow inspiration. The costomediastinal recess is most obvious in the cardiac notch of the left lung.
|
|
Surgical pleurodesis may be performed via thoracotomy or thoracoscopy. This involves mechanically irritating the parietal pleura, often with a rough pad. Moreover, surgical removal of parietal pleura is an effective way of achieving stable pleurodesis. Alternatively, tunneled pleural catheters (TPCs) may be placed in an outpatient setting and often result in auto-pleurodesis, whereby portable vacuum bottles are used to evacuate the pleural fluid.
|
|
Diffuse pleural thickening (DPT) is non-circumscribed fibrous thickening of the visceral pleura with areas of adherence to the parietal pleura and obliteration of the pleural space. It often extends over the area of an entire lobe or lung, with fibrotic areas involving costophrenic angles, apices, lung bases, and interlobar fissures. The thickness ranges from less than 1 mm up to 1 cm or more and may extend for a few millimeters into the lung parenchyma. Fibrous strands (“crow's feet”) extending from the thickened pleura into the lung parenchyma can be often detected on CT scan. Diffuse pleural thickening develops 20 to 40 years after first exposure.

In some cases, the lungs and the pleura were stuck together as well as the intestines to the peritoneal wall. This again matches yellow cerebral softening.
|
|
The visceral pleura receives its blood supply from the bronchial circulation, which also supplies the lungs. The parietal pleura receives its blood supply from the intercostal arteries, which also supply the overlying body wall. The costal and cervical portions and the periphery of the diaphragmatic portion of the parietal pleurae are innervated by the intercostal nerves. The mediastinal and central portions of the diaphragmatic pleurae are innervated by the phrenic nerves.
|
|
The costodiaphragmatic recess, also called the costophrenic recess or phrenicocostal sinus,drugs.com > phrenicocostal-sinus Retrieved May 2011 is a potential space in the pleural cavity, at the posterior-most tips of the cavity, located at the junction of the costal pleura and diaphragmatic pleura (in the costophrenic angle). It measures approximately 5 cm vertically and extends from the eighth to the tenth rib along the mid-axillary line.
|
|
The 10th intercostal nerve terminates at the navel. The twelfth (subcostal) thoracic is distributed to the abdominal wall and groin. Unlike the nerves from the autonomic nervous system that innervate the visceral pleura of the thoracic cavity, the intercostal nerves arise from the somatic nervous system. This enables them to control the contraction of muscles, as well as provide specific sensory information regarding the skin and parietal pleura.
|
|
Finally there's a traverse flow from margins to flat portion of ribs completes the fluid circulation. Absorption occurs into lymphatic vessels at the level of the diaphragmatic pleura.

Hyperthermic intrathoracic chemotherapy (HITOC) is part of a surgical strategy employed in the treatment of various pleural malignancies. The pleura in this situation could be considered to include the surface linings of the chest wall, lungs, mediastinum, and diaphragm. HITOC is the chest counterpart of HIPEC. Traditionally used in the treatment of malignant mesothelioma, a primary malignancy of the pleura, this modality has recently been evaluated in the treatment of secondary pleural malignancies (e.g.

Pleural plaques are the most common manifestation of asbestos exposure, affecting up to 58% of asbestos-exposed workers. The prevalence among the general population exposed environmentally ranges from 0.53 to 8%. Pleural plaques are discrete circumscribed areas of hyaline fibrosis (patches of thickening) of the parietal pleura and rarely the visceral pleura that develop 20 to 40 years after first exposure. Over time, usually more than 30 years, they often become partly calcified.
|
|
Both lungs have a central recession called the hilum at the root of the lung, where the blood vessels and airways pass into the lungs. There are also bronchopulmonary lymph nodes on the hilum. The lungs are surrounded by the pulmonary pleurae. The pleurae are two serous membranes; the outer parietal pleura lines the inner wall of the rib cage and the inner visceral pleura directly lines the surface of the lungs.

These are densely arranged anteriorly. The pleura are shiny between the punctate markings. Lateral aspects of the propodeum are dull. They are overall smooth, except some fine and shallow punctures.
|
|
It occurs when either local or generalized fibrotic changes in the lung or pleura hamper expansion and increase elastic recoil during expiration. Causes include granulomatous disease, necrotising pneumonia and radiation fibrosis.
|
|
Rounded atelectasis (also known as Blesovsky’s or folded lung syndrome) develops from infolding of thickened visceral pleura with collapse of the intervening lung parenchyma. It presents radiographically as a mass and may be mistaken for a tumour. On a CT scan of the chest it appears as a rounded mass like opacity in the peripheral lung adjacent to thickened pleura and with curvilinear opacities which are the bronchi and vessels (comet tail).Batra, P., et al.

Intralobar sequestration (ILS) in which the lesion is located within a normal lobe and lacks its own visceral pleura. Extralobar sequestration (ELS) in which the mass is located outside the normal lung and has its own visceral pleura The blood supply of 75% of pulmonary sequestrations is derived from the thoracic or abdominal aorta. The remaining 25% of sequestrations receive their blood flow from the subclavian, intercostal, pulmonary, pericardiophrenic, innominate, internal mammary, celiac, splenic, or renal arteries.

Pleural fremitus is a palpable vibration of the wall of the thorax caused by friction between the parietal and visceral pleura of the lungs. See pleural friction rub for the auditory analog of this sign.
|
|
Fibrothorax is often a complication of other diseases that cause inflammation of the pleura. These include infections such as an empyema or tuberculosis, or bleeding within the pleural space known as a haemothorax. Exposure to certain substances, such as asbestos, can cause generalised fibrosis of the lungs, which may involve the pleura and lead to fibrothorax. Less common causes of fibrothorax include collagen vascular diseases such as systemic lupus erythematosus, sarcoidosis, and rheumatoid arthritis; kidney failure leading to uraemia; and side effects of certain medications.

Thoracic endometriosis is a rare form of endometriosis where endometrial-like tissue is found in the lung parenchyma and/or the pleura. It can be classified as either pulmonary, or pleural, respectively.Rojas, J. (2014). Endometriosis pulmonar parenquimal.
|
|
It is almost completely without function, but it separates the thoracic cage from the parietal pleura. It depresses the ribs. Contraction of this muscle aids in exertional expiration by decreasing the transverse diameter of the thoracic cage.
|
|
It is used in pleurodesis (fusion of the pleura because of incessant pleural effusions). For this purpose, povidone-iodine is equally effective and safe as talc, and may be preferred because of easy availability and low cost.

The abdomen is the section behind the metathorax, made up of a series of rings, each with a hole for breathing and respiration, called a spiracle, composing three different segmented sclerites: the tergum, pleura, and the sternum. The tergum in almost all species is membranous, or usually soft and concealed by the wings and elytra when not in flight. The pleura are usually small or hidden in some species, with each pleuron having a single spiracle. The sternum is the most widely visible part of the abdomen, being a more or less sclerotized segment.

Routine evacuation keeps the pleura together, resulting in physical agitation by the catheter, which slowly causes the pleura to scar together. This method, though the minimally invasive and minimal cost solution, takes an average of about 30 days to achieve pleurodesis and is therefore the slowest means of achieving pleurodesis among other modalities. Sterile talc powder, administered intrapleurally via a chest tube, is indicated as a sclerosing agent to decrease the recurrence of malignant pleural effusions in symptomatic patients. It is usually performed at the time of a diagnostic thoracoscopy.
|
|
A more significant, though far less common, risk is the surgeon might inadvertently puncture the pleura, a protective coating over the lungs. This could cause blood or air to drain into the chest cavity, hemothorax or pneumothorax, respectively.

The hilum is the large triangular depression where the connection between the parietal pleura (covering the rib cage) and the visceral pleura (covering the lung) is made, and this marks the meeting point between the mediastinum and the pleural cavities. The root is formed by the bronchus, the pulmonary artery, the pulmonary veins, the bronchial arteries and veins, the pulmonary plexuses of nerves, lymphatic vessels, bronchial lymph nodes, and areolar tissue, all of which are enclosed by a reflection of the pleura. The root of the right lung lies behind the superior vena cava and part of the right atrium, and below the azygos vein. That of the left lung passes beneath the aortic arch and in front of the descending aorta; the phrenic nerve, pericardiacophrenic artery and vein, and the anterior pulmonary plexus, lie in front of each, and the vagus nerve and posterior pulmonary plexus lie behind.

Catamenial pneumothorax is a condition of air leaking into the pleural space (pneumothorax) occurring in conjunction with menstrual periods (catamenial refers to menstruation), and or during ovulation, believed to be caused primarily by endometriosis of the pleura (the membrane surrounding the lung or diaphragm).
|
|
The smaller bronchi have a single layer of lymph capillaries, and they are absent in the alveoli. Each lung is surrounded by a serous membrane of visceral pleura, which has an underlying layer of loose connective tissue attached to the substance of the lung.
|
|
Usually, only one joint is affected. 75% of all FMF patients experience joint attacks. # Chest attacks include pleuritis (inflammation of the pleura) and pericarditis (inflammation of the pericardium). Pleuritis occurs in 40% of patients and makes it difficult to breathe or lie flat, but pericarditis is rare.
|
|
Punctate markings across the mseoscutum and scutellum are coarse, deep, and closely arranged. The spaces between the mesoscutum and scutellum are shiny and very narrow. Punctate markings are finer on the axilla, where they are closely arranged. The pleura demonstrate punctate markings which are coarse and deep.
|
|
Mesothelial hyperplasia is a hyperplasia of mesothelial cells in serous membranes (pleura, pericardium, peritoneum). Mesothelial hyperplasia is usually an incidental finding during peritoneal examination during laparotomy or laparoscopy. Grossly, mesothelial hyperplasia is characterized by the presence of small white nodules or flat plaques on the serous surface.
|
|
Joint contractures of the fingers, elbows and knees can develop secondary to skin involvement and can severely impair physical function. While skin involvement is on the foreground, the process may involve any organ, e.g., the eye, heart, diaphragm, pleura, pericardium, and kidneys, as well as the lungs and liver.

Teeth and spines, including those of the rostrum, carapace, tailfan and scaphocerite, show brownish tips. On the abdomen, distinct red transverse bands are visible. The pleura of the first five abdominal somites also show red chromatophores. The eyestalks are reddish, and some chromatophores are visible on the antennular peduncle.
|
|
Plaural plaques are patchy collections of hyalinized collagen in the parietal pleura. They have a holly leaf appearance on X-ray. They are indicators of asbestos exposure, and the most common asbestos-induced lesion. They usually appear after 20 years or more of exposure and never degenerate into mesothelioma.

The four principal regions of an insect body segment are: tergum or dorsal, sternum or ventral and the two pleura or laterals. Hardened plates in the exoskeleton are called sclerites, which are subdivisions of the major regions - tergites, sternites and pleurites, for the respective regions tergum, sternum, and pleuron.
|
|
Each segment is dilineated by an intersegmental suture. Each segment has four basic regions. The dorsal surface is called the tergum (or notum, to distinguish it from the abdominal terga). The two lateral regions are called the pleura (singular: pleuron), and the ventral aspect is called the sternum.

When the parasite-filled crustacean is eaten, the metacercariae hatch in the intestine. These young worms penetrate intestinal wall, peritoneum, the diaphragm and the pleura where they finally reach the lungs. Here they live in pairs, lay eggs that are coughed up in sputum to restart the cycle.
|
|
Intrapulmonary sequestration occurs within the visceral pleura of normal lung tissue. Usually, no communication with the tracheobronchial tree occurs. The most common location is in the posterior basal segment, and nearly two thirds of pulmonary sequestrations appear in the left lung. Venous drainage is usually via the pulmonary veins.

Recurrent somatic fusions of the two genes, NGFI-A–binding protein 2 (NAB2) and STAT6, located at chromosomal region 12q13, have been identified in solitary fibrous tumors. This PA chest radiograph demonstrates an abnormal contour in the right hilar region, with visualization of the pulmonary vessels through the mass (the hilar overlay sign) indicating its posterior mediastinal location. On resection this was found to be a benign solitary fibrous tumor of the pleura. This axial CT image with intravenous contrast (same patient as in the above chest radiograph) reveals what appears to be a posterior mediastinal mass, which was surgically removed and found to be a solitary fibrous tumor of the pleura.

Organs, structured collections of cells with a specific function, mostly sit within the body, with the exception of skin. Examples include the heart, lungs and liver. Many organs reside within cavities within the body. These cavities include the abdomen (which contains the stomach, for example) and pleura, which contains the lungs.
|
|
In some cases of pleurisy, excess fluid builds up in the pleural space. This is called a pleural effusion. The buildup of excess fluid, will more often than not force the two layers of the pleura apart so they don't rub against each other when breathing. This can relieve the pain of pleurisy.

|
In reference to the muscles of the thoracic wall, the intercostal nerves and vessels run just behind the internal intercostal muscles: therefore, they are generally covered on the inside by the parietal pleura, except when they are covered by the innermost intercostal muscles, innermost intercostal membrane, subcostal muscles or the transversus thoracis muscle.
|
|
When the alveoli of the lung are ruptured, as occurs in pulmonary laceration, air may travel beneath the visceral pleura (the membrane lining the lung), to the hilum of the lung, up to the trachea, to the neck and then to the chest wall. The condition may also occur when a fractured rib punctures a lung; in fact, 27% of patients who have rib fractures also have subcutaneous emphysema. Rib fractures may tear the parietal pleura, the membrane lining the inside of chest wall, allowing air to escape into the subcutaneous tissues. Subcutaneous emphysema is frequently found in pneumothorax (air outside of the lung in the chest cavity) and may also result from air in the mediastinum, pneumopericardium (air in the pericardial cavity around the heart).
|
|
Litten's sign, also known as the diaphragm phenomenon, is a paralyzed hemidiaphragm, the portion of the diaphragm in contact with the parietal pleura during respiration in the base of the pleural cavity. It's when the zone of apposition ( the portion of the diaphragm in contact with the parietal pleura during expiration in the base of the pleural cavity') is reduced by the flattening of the diaphragm during inspiration and the pressure in the last intercostal spaces changes from intra-abdominal to intra-thoracic pressure. This partially contributes to the expansion of the rib cages during ventilation. This can be recognized by a slight change of sound when the percussion technique is used during expiration and inspiration in the last intercostal spaces.
|
|
The sign is an imaging finding using a 3.5–7.5 MHz ultrasound probe in the 4th and 5th intercostal spaces in the anterior clavicular line using the M-Mode of the machine. This finding is seen in the M-mode tracing as pleura and lung being indistinguishable as linear hyperechogenic lines and is fairly reliable for diagnosis of a pneumothorax. Even though the stratospheric sign can be an indication of pneumothorax its absence is not at all reliable to rule out pneumothorax as definitive diagnosis usually requires X-ray or CT of thorax. Seashore sign is another eFAST finding usually in the lungs in the M-mode that depicts the glandular echogenicity of the lung abutted by the linear appearance of the visceral pleura.

They have been described as masses that fall between a hemangioma and angiosarcoma. They are vascular tumors that commonly present with an enlarging mass and most commonly involve the lungs, liver, and musculoskeletal system, although many other body sites have been reported, including the head and neck, intestines, lymph nodes, pleura, retroperitoneum, heel, stomach.
|
|
In addition to the usual sources of mummified tissue, bones and teeth, such studies have also examined a range of other tissue samples, including calcified pleura, tissue embedded in paraffin, and formalin-fixed tissue. Efficient computational tools have been developed for pathogen and microorganism aDNA analyses in a small (QIIME) and large scale (FALCON ).

|
Tunneling should be applied if a distal infiltration of the adjacent nerve root is preferred. For thoracic and abdominal surgeries, the surgeon will place the catheter superior to the respective fascias. For thoracic surgeries, the catheter goes superior to the pleura. For all type of abdominal surgeries the catheter should be close to the peritoneum.
|
|
Pleural fluid is a serous fluid produced by the serous membrane covering normal pleurae. Most fluid is produced by the exudation in parietal circulation (intercostal arteries) via bulk flow and reabsorbed by the lymphatic system. Thus, pleural fluid is produced and reabsorbed continuously. The composition and volume is regulated by mesothelial cells in the pleura.
|
|
Rarely, endometriosis can cause endometrium-like tissue to be found in other parts of the body. Thoracic endometriosis occurs when endometrium-like tissue implants in the lungs or pleura. Manifestations of this include coughing up blood, a collapsed lung, or bleeding into the pleural space. Stress may be a cause or a consequence of endometriosis.

In immunology, the Arthus reaction () is a type of local type III hypersensitivity reaction. Type III hypersensitivity reactions are immune complex-mediated, and involve the deposition of antigen/antibody complexes mainly in the vascular walls, serosa (pleura, pericardium, synovium), and glomeruli. This reaction is usually encountered in experimental settings following the injection of antigens.

If the duct is disrupted posteriorly, the secretions leak through the retroperitoneum into the mediastinum via the aortic or esophageal hiatus. Once in the mediastinum, the secretions can either be contained in a mediastinal pseudocyst, lead to enzymatic mediastinitis, or, more commonly, leak through the pleura to enter the chest and form a chronic pancreatic pleural effusion.

Malignant pleural effusion is a condition in which cancer causes an abnormal amount of fluid to collect between the thin layers of tissue (pleura) lining the outside of the lung and the wall of the chest cavity. Lung cancer and breast cancer account for about 50-65% of malignant pleural effusions. Other common causes include pleural mesothelioma and lymphoma.

The carapace shows a sharp antennal spine below the lower orbital angle. The first four abdominal pleura are broadly rounded, the fifth ends in a blunt angle. The sixth somite is 1.5 times longer than the fifth. The telson is elongate and triangular, ending in a narrow rounded posterior margin which bears the usual three pairs of spines.

|
Its face is brownish yellow; gena is brownish black; lunule is large, shiny and orange; its frontal triangle is brownish yellow. Its eye is densely brownish, while its antenna is orange. The thorax is mainly black; postpronotum orange; scutum black; scutellum is reddish orange; pleura black. Its calypter is brownish black and the plumula brownish orange.

Instruments for needle biopsy of the pleura. Definitions of the terms "transudate" and "exudate" are the source of much confusion. Briefly, transudate is produced through pressure filtration without capillary injury while exudate is "inflammatory fluid" leaking between cells. Transudative pleural effusions are defined as effusions that are caused by systemic factors that alter the pleural equilibrium, or Starling forces.

|
The ventral view or sternum follows the same convention, with the prosternum under the prothorax, the mesosternum under the mesothorax and the metasternum under the metathorax. The notum, pleura, and sternum of each segment have a variety of different sclerites and sutures, varying greatly from order to order, and they will not be discussed in detail in this section.

|
All types of asbestos can cause diffuse pleural thickening and a dose-related relationship has been described. It is thought that asbestos fibres that reach the pleura induce subpleural fibroblasts and mesothelial cells to produce scar tissue and collagen deposition, resulting in subpleural thickening. Pleural plaques often coexist with DPT although the latter is rare compared with pleural plaques.

Front of thorax, showing surface relations of bones, lungs (purple), pleura (blue), and heart (red outline). The locations of best auscultation for each heart valve are labeled with "M", "T", "A", and "P". First heart sound: caused by atrioventricular valves – Mitral (M) and Tricuspid (T). Second heart sound caused by semilunar valves – Aortic (A) and Pulmonary/Pulmonic (P).
|
|
The side lobes of the thorax (or pleurae, singular pleura) have rounded ends. The pygidium is well rounded, semicircular or shorter, with an entire margin, and without lateral and posterior projections. In many Phacopidae, where the facial sutures are apparently continuous and well developed, they were evidently nonfunctional in ecdysis, since no separate free cheeks can be found.
|
|
The pericardiacophrenic artery is a long slender branch of the internal thoracic artery. It accompanies the phrenic nerve, between the pleura and pericardium, to the diaphragm, to which it is distributed. It anastomoses with the musculophrenic and superior phrenic arteries. On their course through the thoracic cavity, the pericardiacophrenic arteries are located within and supply the fibrous pericardium.
|
|
In the typical body segment of an insect or many other Arthropoda, there are four principal regions. The dorsal region is the tergum; if the tergum bears any sclerites, those are called tergites. The ventral region is called the sternum, which commonly bears sternites. The two lateral regions are called the pleura (singular pleurum) and any sclerites they bear are called pleurites.
|
|
The abdomen is the largest tagma of the insect, which typically consists of 11–12 segments and is less strongly sclerotized than the head or thorax. Each segment of the abdomen is represented by a sclerotized tergum and sternum. Terga are separated from each other and from the adjacent sterna or pleura by membranes. Spiracles are located in the pleural area.
|
|
Asbestos can cause a variety of lung diseases such as lung cancer. Tobacco smoking and asbestos both have synergistic effects on the development of lung cancer. In smokers who work with asbestos, the risk of lung cancer is increased 45-fold compared to the general population. Asbestos can also cause cancer of the pleura, called mesothelioma – which actually is different from lung cancer.
|
|
The cause is believed to be an autoimmune response against damaged cardiac tissue. This is supported by excellent response to immunosuppressive (steroid) therapy. This condition is a febrile illness caused by immune attack of the pleura and the pericardium. Possible cell mediated immunity led by Helper T-cells and Cytotoxic T-cells is postulated to be important in the pathogenesis of this condition.
|
|
Locations can include the subcutaneous tissue on the scalp, the pleura (pleural effusion), the pericardium (pericardial effusion) and the abdomen (ascites). Edema is usually seen in the fetal subcutaneous tissue, sometimes leading to spontaneous abortion. It is a prenatal form of heart failure, in which the heart is unable to satisfy demand (in most cases abnormally high) for blood flow.

Interventional pulmonology (IP, also called interventional pulmonary medicine) is a maturing medical sub-specialty from its parent specialty of pulmonary medicine. It deals specifically with minimally invasive endoscopic and percutaneous procedures for diagnosis and treatment of neoplastic as well as non-neoplastic diseases of the airways, lungs, and pleura. Many IP procedures constitute efficacious yet less invasive alternatives to thoracic surgery.
|
|
Pulmonary pathology is a subspecialty of anatomic (and especially surgical) pathology that deals with diagnosis and characterization of neoplastic and non-neoplastic diseases of the lungs and thoracic pleura. Diagnostic specimens are often obtained via bronchoscopic transbronchial biopsy, CT-guided percutaneous biopsy, or video- assisted thoracic surgery. These tests can be necessary to diagnose between infection, inflammation, or fibrotic conditions.

It is known under the trade names Pyodine and Betadine, among a plethora of others. It is used in pleurodesis (fusion of the pleura because of incessant pleural effusions). For this purpose, povidone iodine is equally effective and safe as talc, and may be preferred because of easy availability and low cost. PVP is used in some contact lenses and their packaging solutions.

Internal organs viewed from front: lungs (grey), heart (white), liver (purple), stomach (yellow), large intestine (yellow) and small intestine (pink), from Gray's Anatomy. Internal organs viewed from back: spleen (green), kidneys (purple), right lower lung (purple) and pleura (blue), from Gray's Anatomy. In Buddhist scriptures, this practice involves mentally identifying 31 parts of the body, contemplated upon in various ways.
|
|
It may also be put inside the chest to help prevent the recurrence of a pleural effusion due to cancer. However, for scarring down the pleura, talc appears to be the better option. While potentially effective against bacterial infections, its toxicity prevents its use for this purpose. It has been studied in the treatment of warts but is of unclear benefit.
|
|
N. caviae is another species of medical interest. The genus is acid-fast to some degree, it stains only weakly Gram positive. The most common form of human nocardial disease is a slowly progressive pneumonia, the common symptoms of which include cough, dyspnea (shortness of breath), and fever. It is not uncommon for this infection to spread to the pleura or chest wall.
|
|
The cephalon does not end in genal spines. The side lobes of the thorax (or pleurae, singular pleura) have rounded ends. The pygidium is well rounded, semicircular or shorter, with an entire margin, and without lateral and posterior projections. In many Phacopidae, where the facial sutures are apparently continuous and well developed, they were evidently nonfunctional in ecdysis, since no separate free cheeks can be found.

|
Unlike benign germ cell tumors of the mediastinum, malignant mediastinal tumors are usually symptomatic at the time of diagnosis. Most mediastinal malignant tumors are large and cause symptoms by compressing or invading adjacent structures, including the lungs, pleura, pericardium, and chest wall. Seminomas grow relatively slowly and can become very large before causing symptoms. Tumors 20 to 30 cm in diameter can exist with minimal symptomatology.
|
|
Other possible sources of referral pain into the thoracic region include visceral organs like: lungs, gallbladder, stomach, liver duodenum, pleura and cardiac. Middle back pain has long been considered a "red flag" to alert healthcare professionals to the possibility of cancer (metastasis or spread to the spine). This is not a sensitive or specific phenomenon and can therefore not be relied upon in isolation.
|
|
The convex mesonotum is usually covered with hairs and rows of bristles. An important taxonomic character is the precise location of the anterior spiracles on the pleura of the thorax. The metapleuron may be entire or divided by a suture into two halves, and either with a few long bristles glabrous, or pubescent. The legs have stout femora and the hind femora are often laterally compressed.

Pleurosicya mossambica is known by a wide variety of common names, including the toothy goby, common ghost goby, ghost goby, gudgeon, manyhost cling-goby, manyhost goby, Mozambique ghost goby, and reef goby. Its generic name, Pleurosicya, is derived from the Greek pleura, meaning side, and sikya, as in cucumber. Its species name, mossambica, refers to Mozambique, the region in which it was first discovered.

Papillary adenocarcinoma is a histological form of lung cancer that is diagnosed when the malignant cells of the tumor form complex papillary structures and exhibit compressive, destructive growth that replaces the normal lung tissue.Travis WD, Brambilla E, Muller-Hermelink HK, Harris CC (Eds.): World Health Organization Classification of Tumours. Pathology and Genetics of Tumours of the Lung, Pleura, Thymus and Heart. IARC Press: Lyon, France 2004.

The 3rd thorax segment is enlarged, the pleura at the axis slightly longer than that of other segments, and about four times as long at the side removed from the axis. Neighbouring pleurae are displaced because of the large pleurae of the 3rd segment. The back thorax (or opistothorax) consists of about 10 progressively smaller segments with insignificant pleurae. Tail shield (or pygidium) not known.

|
The ground plan of the abdomen of an adult insect typically consists of 11–12 segments and is less strongly sclerotized than the head or thorax. Each segment of the abdomen is represented by a sclerotized tergum, sternum, and perhaps a pleurite. Terga are separated from each other and from the adjacent sterna or pleura by a membrane. Spiracles are located in the pleural area.
|
|
The arrangement on the two sides is not symmetrical. Right side: (superior to inferior) Eparterial bronchus, pulmonary artery, hyparterial bronchus and inferior pulmonary vein Left Side: (superior to inferior) Pulmonary artery, bronchus and inferior pulmonary vein. Also on each hilum there are hilar bronchopulmonary lymph nodes. The parietal pleura surrounding the root of the lung extends downwards from the hilum in a fold called the pulmonary ligament.

|
Group B coxsackieviruses tend to infect the heart, pleura, pancreas, and liver, causing pleurodynia, myocarditis, pericarditis, and hepatitis (inflammation of the liver not related to the hepatotropic viruses). Coxsackie B infection of the heart can lead to pericardial effusion. The development of insulin-dependent diabetes (IDDM) has recently been associated with recent enteroviral infection, particularly coxsackievirus B pancreatitis. This relationship is currently being studied further.

|
At the microscopic level, collagen fibres deposit in a basket weave pattern and form scar tissue. Usually, the underlying condition has to cause intense inflammation of the pleura, though it is unclear exactly how this results in fibrosis. The precise mechanisms producing the fibrosis are not entirely clear. However, research indicates a protein called Transforming Growth Factor beta (TGF-β) plays a central role in producing fibrothorax.
|
|
The endothoracic fascia is deep to the intercostal space The endothoracic fascia is the layer of loose connective tissue deep to the intercostal spaces and ribs, separating these structures from the underlying pleura. This fascial layer is the outermost membrane of the thoracic cavity. The endothoracic fascia contains variable amounts of fat. It becomes more fibrous over the apices of the lungs as the suprapleural membrane.
|
|
Although Epithelioid Hemangioendothelioma typically presents as a low-grade tumor, occasionally, eHAE presents as high grade and more aggressive. eHAE presenting in the pleura, for example, is associated with a much more aggressive and hard to treat course. There is no standard chemotherapy treatment for eHAE at current but success with drugs such as Interferon, Paclitaxel, MAID combination chemotherapy, Thalidomide and Doxorubicin have been reported.
|
|
The anterior divisions of the second, third, fourth, fifth, and sixth thoracic nerves, and the small branch from the first thoracic, are confined to the walls of the thorax, and are named thoracic intercostal nerves. They pass forward in the intercostal spaces below the intercostal vessels. At the back of the chest they lie between the pleura and the posterior intercostal membranes, but soon they run between the internal intercostals and the innermost intercostals then anteriorly they lie between the pleura and the internal intercostals. Near the sternum, they cross in front of the internal mammary artery and transversus thoracis muscle, pierce the intercostales interni, the anterior intercostal membranes, and pectoralis major, and supply the integument of the front of the thorax and over the mamma, forming the anterior cutaneous branches of the thorax; the branch from the second nerve unites with the anterior supraclavicular nerves of the cervical plexus.

While some researchers have proposed that a SFT occupying at least 40% of the affected hemithorax be considered a "giant solitary fibrous tumor",Pinedo-Onofre JA, Robles-Pérez E, Peña-Mirabal ES, Hernández-Carrillo JA, Téllez-Becerra JL. [Giant solitary fibrous tumor of the pleura.] Cir Cir 2010;78:31-43. [Article in Spanish]. no such "giant" variant has yet been recognized within the most widely used pleural tumor classification scheme.

Pleural cavity diseases include pleural mesothelioma which are mentioned above. A collection of fluid in the pleural cavity is known as a pleural effusion. This may be due to fluid shifting from the bloodstream into the pleural cavity due to conditions such as congestive heart failure and cirrhosis. It may also be due to inflammation of the pleura itself as can occur with infection, pulmonary embolus, tuberculosis, mesothelioma and other conditions.
|
|
A pneumothorax is a hole in the pleura covering the lung allowing air in the lung to escape into the pleural cavity. The affected lung "collapses" like a deflated balloon. A tension pneumothorax is a particularly severe form of this condition where the air in the pleural cavity cannot escape, so the pneumothorax keeps getting bigger until it compresses the heart and blood vessels, leading to a life- threatening situation.
|
|
The Intrapulmonary nodes or Lymphatic Vessels of the Lungs originate in two plexuses, a superficial and a deep. The superficial plexus is placed beneath the pulmonary pleura. The deep accompanies the branches of the pulmonary vessels and the ramifications of the bronchi. In the case of the larger bronchi the deep plexus consists of two networks—one, submucous, beneath the mucous membrane, and another, peribronchial, outside the walls of the bronchi.

Lung cancer is an extremely heterogeneous family of malignant neoplasms, with well over 50 different histological variants recognized under the 4th revision of the World Health Organization (WHO) typing system, currently the most widely used lung cancer classification scheme.Travis WD, Brambilla E, Muller-Hermelink HK, Harris CC (Eds.): World Health Organization Classification of Tumours.

The body is smooth, with a black abdomen and a brassy thorax; the tegula is likewise brassy. Near the junction of the thorax' tergites and pleura, there is a silver lengthwise line on each side. The 8th sternite is slightly modified in shape. The legs are glossy, with the fore- and midlegs a smooth and shiny grey except for the black tarsi; the first two tarsus segments are white-tipped.

Entomology and the Law. University of Cambridge. 2002. It is also closely related to Muscina differing primarily in the precise details of larval and adult morphology and in its location. Furthermore, some significant identifying characteristics for the adult flies in the family musicdae include a pair of antennae, three segmented plumose aristae, a frontal suture, well developed calypters, hypo pleura without bristles, and more than one sternopleural bristles.

Endometrial tissue attaches within the thoracic cavity, forming chocolate-like cysts. Generally the parietal pleura is involved, but the lung itself, the visceral layer, the diaphragm, and more rarely the tracheobronchial tree may also be afflicted. The mechanism through which endometrial tissue reaches the thorax remains unclear. Defects in the diaphragm, which are found often in affected individuals, could provide an entry path, as could microembolization through pelvic veins.
|
|
Paraseptal emphysema also called distal acinar emphysema relates to emphysematous change next to a pleural surface, or to a fissure. The cystic spaces known as blebs or bullae that form in paraseptal emphysema typically occur in just one layer beneath the pleura. This distinguishes it from the honeycombing of small cystic spaces seen in fibrosis that typically occurs in layers. This type of emphysema is not associated with airflow obstruction.

James Tissot, Jesus Wept (Jésus pleura) "Jesus wept" (, edákrysen ho Iesoús "Then Jesus Wept") is a phrase famous for being the shortest verse in the King James Version of the Bible, as well as many other versions.In the NIV, is the shortest biblical verse. Whereas the KJV reads "And Job spake, and said," the NIV simply has "He said". It is not the shortest in the original languages.

The paravertebral block provides unilateral analgesia, but bilateral blocks can be performed for abdominal surgeries. Since it is a unilateral block, it may be chosen over epidurals for patients who can't tolerate the hypotension that follows bilateral sympathectomy. The paravertebral space is located a couple centimeters lateral to the spinous process and is bounded posteriorly by the superior costotransverse ligament and anteriorly by the parietal pleura. Complications include pneumothorax, vascular puncture, hypotension, and pleural puncture.

Most people with cancer of unknown primary origin have widely disseminated and incurable disease, although a few can be cured through treatment. With treatment, typical survival with CUP ranges from 6 to 16 months. Survival rates are lower in cases with visceral metastatic disease, ranging from 6 to 9 months. Survival rates are higher when the cancer is more limited to lymph nodes, pleura, or peritoneal metastasis, which ranges from 14 to 16 months.

The lesions of AAH are <5 mm, can be single or multiple, and have a ground glass appearance on CT imaging. As more genetic mutations and disregulation of normal cell signaling pathways accumulate, AAH can progress to adenocarcinoma in situ (AIS). AIS lesions are classified as small tumors <3 cm with abnormal type II pneumocyte cell growth that is limited to the alveolar spaces i.e. without invasion into the stroma, pleura, or vasculature.

Prognosis is much worse for stage III or IV thymomas as compared with stage I and II tumors. Invasive thymomas uncommonly can also metastasize, generally to pleura, bones, liver or brain in approximately 7% of cases. A study found that slightly over 40% of observed patients with stage III and IV tumors survived for at least 10 years after diagnosis. The median age of these patients at the time of thymoma diagnosis was 57 years.

In anatomy, a potential space is a space between two adjacent structures that are normally pressed together (directly apposed). The pleural space, between the visceral and parietal pleura of the lung, is a potential space. Though it only contains a small amount of fluid normally, it can sometimes accumulate fluid or air that widens the space. The pericardial space is another potential space that may fill with fluid (effusion) in certain disease states (e.g.

Variety of male structures in Phlebotominae (Diptera, Psychodidae) The ground plan of the abdomen of an adult insect typically consists of 11–12 segments and is less strongly sclerotized than the head or thorax. Each segment of the abdomen is represented by a sclerotized tergum, sternum, and perhaps a pleurite. Terga are separated from each other and from the adjacent sterna or pleura by a membrane. Spiracles are located in the pleural area.
|
|
Chemicals such as bleomycin, tetracycline (e.g., minocycline), povidone-iodine, or a slurry of talc can be introduced into the pleural space through a chest drain. The instilled chemicals cause irritation between the parietal and the visceral layers of the pleura which closes off the space between them and prevents further fluid from accumulating. Pharmacy-prepared chemicals for pleurodesis should be clearly labeled "NOT FOR IV ADMINISTRATION" to avoid potentially fatal wrong-site medication errors.
|
|
This sign is a normal finding. In absence of a seashore sign or presence of a stratosphere sign, pneumothorax is likely. B-lines or "comet trails" are echogenic bright linear reflections beneath the pleura that are usually lost with any air between the probe and the lung tissue and therefore whose presence with seashore sign indicates absence of a pneumothorax. Sinusoid sign is another M-mode finding indicating presence of pleural effusion.

Malignant mesothelioma is an aggressive and incurable tumour caused by asbestos arising from mesothelial cells of the pleura, peritoneum (the lining of the abdominal cavity) and rarely elsewhere. Pleural mesothelioma is the most common type of mesothelioma, representing about 75 percent of cases. Peritoneal mesothelioma is the second most common type, consisting of about 10 to 20 percent of cases. Mesothelioma appears from 20 to 50 years after the initial exposure to asbestos.

To the right is the azygos veins and thoracic duct, and to the left is the left pleura and lung. In front of the descending thoracic aorta lies the root of the left lung, the pericardium, the esophagus, and the diaphragm. The esophagus, which is covered by a nerve plexus lies to the right of the descending thoracic aorta. Lower, the esophagus passes in front of the aorta, and ultimately is situated on the left.

Thomas Wakley Warren carried out an autopsy on White assisted by Hall and Dr Francis Reid. He concluded that death was caused by inflammation of the pleura and cardiac covering, which he recorded on the death certificate. Hall sent a separate report on the death to the Army Medical Department, noting that White's back was well healed. White's body was sent for burial and the vicar was told he had died of a liver complaint.

A boy with pertussis The classic symptoms of pertussis are a paroxysmal cough, inspiratory whoop, and fainting, or vomiting after coughing. The cough from pertussis has been documented to cause subconjunctival hemorrhages, rib fractures, urinary incontinence, hernias, and vertebral artery dissection. Violent coughing can cause the pleura to rupture, leading to a pneumothorax. Vomiting after a coughing spell or an inspiratory whooping sound on coughing, almost doubles the likelihood that the illness is pertussis.

|
The central area of the cephalon (or glabella) is elongated, reaching the anterior border, but its features are strongly effaced, almost showing no furrows. The frontal 14 or 15 segments (or prothorax) can readily be distinguished from the terminal 9 to 11 (forming the opisthothorax). The last segment of the prothorax may carry a large spine. The tips of the pleura are rounded, which is unlike the usual pointed terminations in other Olenellina.

Mesothelioma is a rare primary tumour of the connective tissue, originates in the serous membranes of the pleura, peritoneum or pericardium. Peritoneal involvement is reported in 25% of cases. Imaging features include ascites, diffuse irregular nodular peritoneal thickening, invasion of omenta and mesentery with the formation of omental cakes, and mesenteric masses and bowel wall thickening. Coexistence of pleural abnormalities with positive occupational asbestos exposure history in absence detectable primary tumour goes more in favor of mesothelioma.

The specimens of Aspidopleura baltica were first studied by Gary A.P. Gibson, with his 2009 type description being published in the journal ZooKeys. The generic name wash coined by Gary Gibson as a combination of the supposed Greek words aspido meaning "shield" and pleuro, meaning "side". This is in reference to the shape and overall structure of the acropleuron. The proper words for "shield" and "side" in Greek are however ἀσπίς (aspis) and πλευρόν (pleuron) or πλευρά (pleura).

Debridement of damaged tissue can shorten the trachea by as much as 50%.Riley et al. (2004). pp. 550–51. Repair of extensive tears can include sewing a flap of tissue taken from the membranes surrounding the heart or lungs (the pericardium and pleura, respectively) over the sutures to protect them. When lung tissue is destroyed as a result of TBI complications, pneumonectomy or lobectomy (removal of a lung or of one lobe, respectively) may be required.
|
|
A Simon focus is a tuberculosis (TB) nodule that can form in the apex of the lung when a primary TB infection elsewhere in the body spreads to the lung apex via the bloodstream. Simon focus nodules are often calcified. The initial lesion is usually a small focus of consolidation, less than 2cm in diameter and located within 1 to 2 cm of the apical pleura. In adolescence, Simon foci may become reactivated and develop into Assmann foci.
|
|
Pneumonolysis, sometimes referred to as plombage, is the separation of an adherent lung from the pleura, to permit collapse of the lung. It was formerly used to treat tuberculosis before effective medications were developed. The underlying theory of the treatment was the belief that if the diseased lobe of the lung was physically forced to collapse, it would heal quickly. There were positive results in tuberculosis therapy following plombage in the decades of the 1930s, 1940s and early-1950s.
|
|
Malignancy is characterized by local invasion and metastases, usually to the liver, omentum and peritoneum. However, cases of metastases to bone, pleura, lungs and retroperitoneum have been seen. In distinction to gastric adenocarcinoma or gastric/small bowel lymphoma, malignant lymphadenopathy (swollen lymph nodes) is uncommon (<10%) and thus imaging usually shows absence of lymph node enlargement. If metastases are not present, other radiologic features suggesting malignancy include: size (>5 cm), heterogeneous enhancement after contrast administration and ulcerations.
|
|
Complications can occur following a hemothorax, and are more likely to occur if the blood has not been adequately drained from the pleural cavity. Blood that remains within the pleural space can become infected, and is known as an empyema. The retained blood can also irritate the pleura, causing scar tissue to form. If extensive, this scar tissue can encase the lung, restricting movement of the chest wall, and is then referred to as a fibrothorax.
|
|
Treatment of diving barotrauma depends on the symptoms. Lung over-pressure injury may require a chest drain to remove air from the pleura or mediastinum. Recompression with hyperbaric oxygen therapy is the definitive treatment for arterial gas embolism, as the raised pressure reduces bubble size, low inert gas partial pressure accelerates inert gas solution and high oxygen partial pressure helps oxygenate tissues compromised by the emboli. Care must be taken when recompressing to avoid a tension pneumothorax.

According to the Australian Surveillance of Australian Workplace Based Respiratory Events (SABRE) scheme, DPT accounted for 22% of all asbestos-related diseases. It usually begins with an inflammation of the pleura that is accompanied by a pleural effusion. Most patients complain of exertional breathlessness, however, chest pain has been also associated with this disorder. DPT has a significant impact on pulmonary function, causing a decrease in forced vital capacity, reducing total lung capacity and diffusing capacity.
|
|
The root of the lung is located at the hilum of each lung, just above the middle of the mediastinal surface and behind the cardiac impression of the lung. It is nearer to the back (posterior border) than the front (anterior border). The root of the lung is connected by the structures that form it to the heart and the trachea. The rib cage is separated from the lung by a two- layered membranous coating, the pleura.
|
|
The thorax has approximately 25 segments, the pleura about 1½× as wide as the axis, excluding the genal spines. The 3rd segment carries extra large pleural spines (or macropleural spines) that reach back only to the tip of the 5th pleural spines. The segments look degenerated behind the 15th (or an opisthothorax can be distinguished). The tailshield (or pygidium) is very small and subquadrate in shape, and carries one or two pairs of small marginal spines.
|
|
The diagnosis may be suspected based on chest X-ray and CT scan findings, and is confirmed by either examining fluid produced by the cancer or by a tissue biopsy of the cancer. Prevention centers around reducing exposure to asbestos. Treatment often includes surgery, radiation therapy, and chemotherapy. A procedure known as pleurodesis, which involves using substances such as talc to scar together the pleura, may be used to prevent more fluid from building up around the lungs.

Similar to other local anesthetics, benzonatate is a potent voltage-gated sodium channel inhibitor. After absorption and circulation to the respiratory tract, benzonatate acts as a local anesthetic, decreasing the sensitivity of vagal afferent fibers and stretch receptors in the bronchi, alveoli, and pleura in the lower airway and lung. This dampens their activity and reduces the cough reflex. Benzonatate also has central antitussive activity on the cough center in central nervous system at the level of the medulla.

The bronchial arteries supply blood to the bronchi and connective tissue of the lungs. They travel with and branch with the bronchi, ending about at the level of the respiratory bronchioles. They anastomose with the branches of the pulmonary arteries, and together, they supply the visceral pleura of the lung in the process. Note that much of the oxygenated blood supplied by the bronchial arteries is returned via the pulmonary veins rather than the bronchial veins.

Choerades marginata can reach a body length of about and a wings length of .J.K. Lindsey Ecology of Commanster In males the first antennal segment is about 1.8 - 2.1 times as long as the second one, while in female is 3 times longer. The sides of thorax (pleura) and the humeral callus are distinctly tomentose and scutum has only few, normal hairs. The lateral sclerites (mesopleuron) have a greyish-brown tomentum, with sparse yellow and black hairs all over.

Gene expression profiling shows considerable variance from other DLBCLs and similarity to Hodgkin disease. PMLBCL is CD20 positive, expresses pan-B markers including CD79a, and has clonal immunoglobulin gene rearrangements and mRNA but paradoxically does not express cytoplasmic or cell surface immunoglobulin. Clinically, PMLBCL is unusual in several respects. Despite 80% PMLBCL being stage I or II, the presenting anterior mediastinal mass is often over 10 cm and is locally invasive of lung, chest wall, pleura, and pericardium.

The Lumbocostal triangle or Bochdalek's foramen is a space between the costal and lumbar parts of the diaphragm. The base of this triangular space is formed by muscle attachments originating from the XII rib and muscle fibers attaching to the lateral arcuate ligament. The apex of the triangle is oriented towards the tendinous centre of the diaphragm. Parietal pleura and renal capsule are in contact in this space, so possible infection can be transmitted through this space.

|
The dorsal surface is called the tergum (or notum) to distinguish it from the abdominal terga. The two lateral regions are called the pleura (singular: pleuron) and the ventral aspect is called the sternum. In turn, the notum of the prothorax is called the pronotum, the notum for the mesothorax is called the mesonotum and the notum for the metathorax is called the metanotum. Continuing with this logic, the mesopleura and metapleura, as well as the mesosternum and metasternum, are used.

Lumbar plexus and its branches. Since the Lumbar plexus and Sacral plexus are interconnected, they are sometimes referred to as the Lumbosacral plexus. The intercostal nerves that give rami to the chest and to the upper parts of the abdominal wall efferent motor innervation and to the pleura and peritoneum afferent sensory innervation are the only ones that do not originate from a plexus. The ventral rami of L1-L5 spinal nerves with a contribution of T12 form Lumbar plexus.

The thoracic ganglia are paravertebral ganglia. The thoracic portion of the sympathetic trunk typically has 12 thoracic ganglia. Emerging from the ganglia are thoracic splanchnic nerves (the cardiopulmonary, the greater, lesser, and least splanchnic nerves) that help provide sympathetic innervation to abdominal structures. The thoracic part of sympathetic trunk lies posterior to the costovertebral pleura and is hence not a content of the posterior mediastinum Also, the ganglia of the thoracic sympathetic trunk have both white and gray rami communicantes.

It innervates the bronchial tree and the visceral pleura. According to the relation of nerves to the root of the lung, the pulmonary plexus is divided into the anterior pulmonary plexus, which lies in front of the lung and the posterior pulmonary plexus, which lies behind the lung. The anterior pulmonary plexus is close in proximity to the pulmonary artery. The posterior pulmonary plexus is bounded by the superior edge of the pulmonary artery and the lower edge of the pulmonary vein.

White was afterwards admitted to hospital where he initially progressed well but eventually deteriorated and died on 11 July. Am army autopsy recorded that White's death was by natural causes, resulting from an inflammation of the pleura and cardiac covering, and his body was sent for a church burial. The vicar, however, had learnt of the flogging and alerted the Middlesex coroner Thomas Wakley. Wakley, an opponent of flogging, ordered an inquest and arranged for two further autopsies to be performed.

But bronchial circulation supplies fully oxygenated arterial blood to the lung tissues themselves. This blood supplies the bronchi and the pleura to meet their nutritional requirements. Because of the dual blood supply to the lungs from both the bronchial and the pulmonary circulation, this tissue is more resistant to infarction. An occlusion of the bronchial circulation does not cause infarction, but it can still occur in pulmonary embolism when the pulmonary circulation is blocked and the bronchial circulation cannot fully compensate for it.

In those with HIV, this occurs in more than 50% of cases. Notable extrapulmonary infection sites include the pleura (in tuberculous pleurisy), the central nervous system (in tuberculous meningitis), the lymphatic system (in scrofula of the neck), the genitourinary system (in urogenital tuberculosis), and the bones and joints (in Pott disease of the spine), among others. Spread to lymph nodes is the most common. An ulcer originating from nearby infected lymph nodes may occur and is painless, slowly enlarging and has an appearance of "wash leather".

The supraclavicular and infraclavicular blocks can be performed for surgeries on the humerus, elbow, and hand. These blocks are indicated for the same surgeries but they provide different views of the nerves, so it depends on the individual patient's anatomy to determine which block should be performed. A pneumothorax is a risk with these blocks, so the pleura should be checked with ultrasound to make sure the lung was not punctured during the block. The axillary block is indicated for elbow, forearm, and hand surgery.

The Burlingiidae constitute a family of trilobites of uncertain affinity, that lived during the Middle to lowest Upper Cambrian (Acadoparadoxides pinus- to Agnostus pisiformis-zone). Burlingiids have a cosmopolitan distribution, can be found in deposits that originate from outside the continental shelves, and may have been planktonic. They are characterized by their oval shape, small size (less than ), proparian sutures, and non-functional articulations of the thorax. Uniquely the anterior borders of the pleura are raised, and there are between 8 and 15 thorax segments.

Hussain is a multifaceted man, and his contributions as a surgeon, researcher, explorer and photographer have been exemplary. He has authored 50 scientific papers in national and international medical journals. He is an award-winning author who has written fourteen books on as diverse a subjects as religion, culture, history and international relations. He has described a number of new surgical techniques and has invented two medical devices: the pleura-peritoneal shunt and a special endotracheal tube to supply oxygen during fiberoptic broncchoscopy in awake patients.

A subpulmonic effusion is excess fluid that collects at the base of the lung, in the space between the pleura and diaphragm. It is a type of pleural effusion in which the fluid collects in this particular space, but can be "layered out" with decubitus chest radiographs. There is minimal nature of costophrenic angle blunting usually found with larger pleural effusions. The occult nature of the effusion can be suspected indirectly on radiograph by elevation of the right diaphragmatic border with a lateral peak and medial flattening.

Exposure to asbestos fibers has been recognized as an occupational health hazard since the early 20th century. Numerous epidemiological studies have associated occupational exposure to asbestos with the development of pleural plaques, diffuse pleural thickening, asbestosis, carcinoma of the lung and larynx, gastrointestinal tumors, and diffuse malignant mesothelioma of the pleura and peritoneum. Asbestos has been widely used in many industrial products, including cement, brake linings, gaskets, roof shingles, flooring products, textiles, and insulation. Commercial asbestos mining at Wittenoom, Western Australia, took place from 1937 to 1966.

Fibrosis in the pleura may be produced intentionally using a technique called pleurodesis to prevent recurrent punctured lung (pneumothorax), and the usually limited fibrosis that this produces can rarely be extensive enough to lead to fibrothorax. The condition is most often diagnosed using an X-ray or CT scan, the latter more readily detecting mild cases. Fibrothorax is often treated conservatively with watchful waiting but may require surgery. The outlook is usually good as long as there is no underlying pulmonary fibrosis or complications following surgery.

Using the upper limit of the sternal depression as a guide, the deformed cartilages are removed one-by-one, using sharp and blunt dissection. The lower tip of the sternum is then grabbed with a towel-clip and, using blunt dissection, is freed of tissue connections with the pericardium and the pleura. The sternum is then forcefully bent forward into a corrected position. To keep the sternum elevated, a piece of mesh is placed under the mobilized sternum and sutured under moderate tension bilaterally to the stumps of the ribs.

Like all burlingiids, Schmalenseeia is small (less than 1 cm long), has an overall ovate shape, proparian facial sutures, and raised anterior borders of the pleura. Schmalenseeia has between 7 and 9 thorax segments, while Burlingia has between 10 and 15. In Burlingia it is however difficult to determine where the thorax meets the pygidium, particularly because uniquely, the pleurae of the pygidium are not fused. All Schmalenseeia-species with the exception of S. acutangula have a glabella that tapers forward, and is connected with the anterior border by a ridge (the so-called plectrum).

Patients who develop peritonitis may get localized abscesses in the right or left subphrenic space. The right side is more common due to the high frequency of ruptured appendices and perforated duodenal ulcers. Two common approaches to draining a subphrenic abscess are 1) incision inferior to or through the bed of the 12th rib (no need to create an opening in the pleura or peritoneum) 2) an anterior subphrenic abscess is often drained through a subcostal incision located inferior and parallel to the right costal margin. It is also associated with peritonitis.

Pleural empyema is a collection of pus in the pleural cavity caused by microorganisms, usually bacteria. Often it happens in the context of a pneumonia, injury, or chest surgery. It is one of the various kinds of pleural effusion. There are three stages: exudative, when there is an increase in pleural fluid with or without the presence of pus; fibrinopurulent, when fibrous septa form localized pus pockets; and the final organizing stage, when there is scarring of the pleura membranes with possible inability of the lung to expand.

Clinical presentation of sparganosis most often occurs after the larvae have migrated to a subcutaneous location. The destination of the larvae is often a tissue or muscle in the chest, abdominal wall, extremities, or scrotum, although other sites include the eyes, brain, urinary tract, pleura, pericardium, and spinal canal. The early stages of disease in humans are often asymptomatic, but the spargana typically cause a painful inflammatory reaction in the tissues surrounding the subcutaneous site as they grow. Discrete subcutaneous nodules develop that may appear and disappear over a period of time.

This category includes findings that are minor and not suggestive of TB disease. These findings require no follow-up evaluation.. Chest x-ray of pleural thickening post-primary tuberculosis #Pleural thickening - Irregularity or abnormal prominence of the pleural margin, including apical capping (thickening of the pleura in the apical region). Pleural thickening can be calcified. #Diaphragmatic tenting - A localized accentuation of the normal convexity of the hemidiaphragm as if “pulled upwards by a string.” #Blunting of costophrenic angle (in adults)—Loss of sharpness of one or both costophrenic angles.

In flies of the order Diptera, the prostigma (also called stigma anteriore or anterior spiracle) is the anterior of the two pairs of spiracles opening on the pleura. The mesothoracic (anterior) pair is located between the pro- and mesothorax and the metathoracic pair (developed mainly in nematocerous Diptera) between the meso- and metathothorax. The following illustration shows the prostigma as number 13 on the right side of the image. The function of the prostigma (as well as the anterior stigma) is to provide an airway into the insect's thorax to facilitate respiration.

After pulling the left lung aside, the layer (mediastinal pleura) above the left arch is incised and the left arch and the ligamentum arteriosum are dissected out and separated from the surrounding structures. The ligamentum is divided and two vascular clamps are placed on the junction of the left arch with the descending aorta. After division the two aortic ends are oversewn with 2 running layers of non- absorbable sutures. The end of the left arch is now further dissected from the mediastinal tissues for relief of any remaining constricting mechanism.

This fluid can lead to complications such as hypoxia due to lung collapse from the fluid, or fibrothorax if scarring occurs. Repeated effusions may require chemical (talc, bleomycin, tetracycline/doxycycline), or surgical pleurodesis, in which the two pleural surfaces are scarred to each other so that no fluid can accumulate between them. This is a surgical procedure that involves inserting a chest tube, then either mechanically abrading the pleura or inserting the chemicals to induce a scar. This requires the chest tube to stay in until the fluid drainage stops.

Diffuse large B-cell lymphoma associated with chronic inflammation (DLBCL-CI) is an Epstein-Barr virus-associated lymphoproliferative disease arising in persons with a long and persistent history of chronic inflammation. The disease's lesions consist of large, mature-appearing B-cells infiltrating the lung's pleura and nearby tissues. Most cases have occurred in patients who were given a pneumothorax (i.e. therapeutic introduction of air into the chest cavity in order to collapse and thereby "rest" the lung) to treat pulmonary tuberculosis that had progressed to a pyothorax (i.e.

With the discovery of gold around 1872 and the increased population that brought, mostly single men, then the arrival of Chinese miners, labourers and merchants who came to dominate the population, policing in the late 1870s became vastly more complex. He was temporarily appointed Chief Warden for District A of the goldfields in October 1879 while J. G. Knight was on leave. He was able to alert the Resident to the presence of cattle infected with "pleura" (perhaps tuberculosis). He was appointed J.P. and Special Magistrate in 1884.

The report pointed out that the thoracic cavity was not penetrated. # This bullet produced contusions both of the right apical parietal pleura and of the apical portion of the right upper lobe of the lung. The bullet contused the strap muscles of the right side of the neck, damaged the trachea, and exited through the anterior surface of the neck. # The single bullet theory of the Warren Commission Report places a bullet wound at the sixth cervical vertebra (C6) of the vertebral column, which is consistent with below the ear.

In interviews, Zevon described a lifelong phobia of doctors and said he seldom consulted one. He had started working out, and he looked physically fit. Shortly before playing at the Edmonton Folk Music Festival in 2002, he started feeling dizzy and developed a chronic cough. After a period of suffering with pain and shortness of breath, Zevon was encouraged by his dentist to see a physician; he was diagnosed with pleural mesothelioma, a cancer (usually caused by exposure to asbestos) that affects the pleura, a thin membrane around the lungs and chest lining.

Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma. People who worked in jobs with high asbestos dust exposure are at the highest risk of developing asbestos-related disease. However, exposure to asbestos may also occur in the worker’s home due to dust that has accumulated on the worker's clothing (para- occupational exposure).

There are no spines between the genal spines and the glabella (or metafixigenal spines). The pygidium has 19-21 axial rings, each with a spine on its midpoint. The part of the pygidium outside the axis (or pleura) has 5–6 segments that get longer further to the back, with rounded pleural bands, clearly incised furrows between the bands and vertical spines near where each posterior band converts into a lappet. There are 5 pairs of lappets that grow only from the posterior pleural bands, and are longer than the corresponding pleural bands.

Pulmonary interstitial emphysema (PIE) is a collection of air outside of the normal air space of the pulmonary alveoli, found instead inside the connective tissue of the peribronchovascular sheaths, interlobular septa, and visceral pleura. (This supportive tissue is called the pulmonary interstitium.) This collection of air develops as a result of alveolar and terminal bronchiolar rupture. Pulmonary interstitial emphysema is more frequent in premature infants who require mechanical ventilation for severe lung disease. Infants suffering from pulmonary interstitial emphysema are typically recommended for admission to a neonatal intensive care unit.

In 15–20% of active cases, the infection spreads outside the lungs, causing other kinds of TB. These are collectively denoted as "extrapulmonary tuberculosis". Extrapulmonary TB occurs more commonly in people with a weakened immune system and young children. In those with HIV, this occurs in more than 50% of cases. Notable extrapulmonary infection sites include the pleura (in tuberculous pleurisy), the central nervous system (in tuberculous meningitis), the lymphatic system (in scrofula of the neck), the genitourinary system (in urogenital tuberculosis), and the bones and joints (in Pott disease of the spine), among others.

The smaller species eat sea-floor invertebrates such as polychaetes and crustaceans, but the larger righteye flounders, such as H. hippoglossus, which grows up to in length, feed on other fishes and cephalopods, as well. They include many important commercially fished species, including not only the various fish called flounders, but also the European plaice, the halibuts, the lemon sole, the common dab, the Pacific Dover sole, and the flukes. The name of the family is derived from the Greek πλευρά (pleura), meaning "rib" or "side", and νηκτόν (nekton), meaning "swimming".

Systemic-onset juvenile idiopathic arthritis (or the juvenile onset form of Still's disease) is a type of juvenile idiopathic arthritis (JIA) with extra- articular manifestations like fever and rash apart from arthritis. It was originally called systemic-onset juvenile rheumatoid arthritis or Still's disease. Predominantly extra-articular manifestations like high fevers, rheumatic rash, enlargement of the liver and spleen, enlargement of the lymph nodes, and anemia. Others manifestations include inflammation of the pleura, inflammation of the pericardium, inflammation of the heart's muscular tissue, and inflammation of the peritoneum are also seen.

While a student Williams published in the Annals of Philosophy for July 1823 a paper on the low combustion of a candle. He published in 1828 Rational Exposition of the Physical Signs of the Diseases of the Lungs and Pleura, dedicated to Sir Henry Halford, of which a third edition appeared in 1835. He wrote in 1833 ten articles for the Cyclopædia of Practical Medicine; and in 1840 the part on diseases of the chest in Alexander Tweedie's Library of Medicine. Williams collaborated during the early 1830s with James Hope the cardiologist in research on heart sounds.

The elephant is the only mammal known to have no pleural space. Rather, the parietal and visceral pleura are both composed of dense connective tissue and joined to each other via loose connective tissue. This lack of a pleural space, along with an unusually thick diaphragm, are thought to be evolutionary adaptations allowing the elephant to remain underwater for long periods of time while breathing through its trunk which emerges as a snorkel. In the elephant the lungs are attached to the diaphragm and breathing relies mainly on the diaphragm rather than the expansion of the ribcage.

The Means–Lerman scratch is an uncommon type of heart murmur which occurs in patients with hyperthyroidism. It is a mid-systolic scratching sound best heard over the upper part of the sternum or second left intercostal space at the end of expiration. The murmur results from the rubbing of the pericardium against the pleura in the context of hyperdynamic circulation and tachycardia,Recognizing Thyroid Storm in the Neurologically Impaired Patient: Pathophysiology at Medscape and may mimic the sound of a pericardial rub. The sign was described by J. Lerman M.D. and J. H. Means M.D. of Massachusetts General Hospital in 1932.

Maddalena Carini was born on 1 March 1917 in Pavia as the last of seven children to Giuseppe Carini and Francesca Bianchi Martina. Her father died in 1930 and her mother died in 1943. Carini began to suffer from an aggressive form of tuberculosis in 1927 in the pleura and the peritoneum and so had to spend long periods of time in a sanatorium until 1937. This ailment was known to have run through the generations. She was operated on at the age of eighteen for appendicitis coupled with peritonitis, and was treated at home until 1945 with little to no improvement.

Rheumatoid pleuritis, a form of pleural effusion, is an uncommon complication of rheumatoid arthritis, occurring in 2-3% of patients (Walker and Wright, 1967; Naylor, 1990) Rheumatoid pleura most often appears as an erythematous exanthema, discoloration, or gray discoloration and may grow into a tender, inflamed mass. Rheumatoid patency is a nonspecific condition characterized by inflammation of the aorta or valve, so as to alter the blood-flow to the aortic valve. Rheumatoid patency typically occurs in older patients, and there is a significant risk for severe, late complications such as aortic valve stenosis, heart valve stenosis.

The Latin anatomical name is tunica serosa. Serous membranes line and enclose several body cavities, known as serous cavities, where they secrete a lubricating fluid which reduces friction from muscle movement. Serosa is entirely different from the adventitia, a connective tissue layer which binds together structures rather than reducing friction between them. The serous membrane covering the heart and lining the mediastinum is referred to as the pericardium, the serous membrane lining the thoracic cavity and surrounding the lungs is referred to as the pleura, and that lining the abdominopelvic cavity and the viscera is referred to as the peritoneum.

He was born in Chicago, Illinois. He was also the retired Executive Director of Toastmasters International, having served in that position for 26 years.Olympic Wrestler Succumbs to Rare Cancer He died in Dana Point, California at age 72 from mesothelioma, a rare asbestos-linked cancer of the pleura.

The condition was known at the time as "adreno-genital syndrome", although the term now used is congenital adrenal hyperplasia. As part of this work, Broster devised a new method for adrenalectomy which he reported in a 1932 paper. At the time, operations of this type often involved resection of a rib so that the surgeon could gain access to the adrenal gland. In Broster's less destructive technique, a long, oblique incision was made over the rib that covered the adrenal gland and the rib was fractured, allowing the incision to be continued through the parietal pleura.

In countries where cow milk infected with Mycobacterium bovis has been eliminated (due to culling of infected cows and pasteurization), primary tuberculosis is usually caused by Mycobacterium tuberculosis and almost always begins in the lungs. Typically, the inhaled bacilli implant in the distal airspaces of the lower part of the upper lobe or the upper part of the lower lobe, usually close to the pleura. As sensitization develops, a 1- to 1.5-cm area of gray-white inflammation with consolidation emerges, known as the Ghon focus. In most cases, the center of this focus undergoes caseous necrosis.

He spoke for 84 minutes before completing his speech and accepting medical attention. His opening comments to the gathered crowd were, "Ladies and gentlemen, I don't know whether you fully understand that I have just been shot, but it takes more than that to kill a Bull Moose.". Afterwards, probes and an x-ray showed that the bullet had lodged in Roosevelt's chest muscle, but did not penetrate the pleura. Doctors concluded that it would be less dangerous to leave it in place than to attempt to remove it, and Roosevelt carried the bullet with him for the rest of his life.

This section of Anathomia also describes the pleura and notes the importance of distinguishing between pulmonary pathologies including true pleurisy, false pleurisy, and pneumonia. His descriptions of the larynx and epiglottis are very rudimentary. Mondino describes the closure of an incised intestinal wound by having large ants bite on its edges and then cutting off their heads, which one scholar interprets as an anticipation of the use of staples in surgery. Anathomia also includes a detailed passage on the surgical treatment of a hernia, both with and without castration, as well as a description of a type of cataract surgery.

The tribunal was established pursuant to the as an inferior court and a court of record. An appeal may lie to the Court of Appeal of New South Wales in certain circumstances. It has exclusive jurisdiction to deal with claims for injuries arising out of the diseases such as aluminosis, asbestosis, asbestos induced carcinoma, asbestos related pleural disease, bagassosis, berylliosis, byssinosis, coal dust pneumoconiosis, farmers’ lung, hard metal pneumoconiosis, pleural and peritoneal mesothelioma, silicosis, silico- tuberculosis and talcosis. It also has jurisdiction over any other pathological condition of the lungs, pleura or peritoneum that is attributable to dust.

A tension pneumothorax, in which air builds up in the pleural cavity and exerts pressure on the organs within the chest, makes it more likely that air will enter the subcutaneous tissues through pleura torn by a broken rib. When subcutaneous emphysema results from pneumothorax, air may enter tissues including those of the face, neck, chest, armpits, or abdomen. Pneumomediastinum can result from a number of events. For example, foreign body aspiration, in which someone inhales an object, can cause pneumomediastinum (and lead to subcutaneous emphysema) by puncturing the airways or by increasing the pressure in the affected lung(s) enough to cause them to burst.

A worker at 5x life size, demonstrating the metallic colour The predominant metallic colour is green, but can vary by region, ranging from metallic green to purple. In the Flinders Ranges of South Australia and Alice Springs, the colour of the ants shifts from the typical green to a dark purple colour. In areas with more rainfall such as the New South Wales tablelands and Victorian savannahs, green-head ants are mostly green with purplish tints seen on the sides of the mesosoma. In the northern regions of New South Wales and Queensland, the alitrunk is reddish-violet, which shades into golden around the lower portions of the pleura.

This PA chest radiograph demonstrates an abnormal contour in the right hilar region, with visualization of the pulmonary vessels through the mass (the hilar overlay sign) indicating its posterior mediastinal location. On resection this was found to be a benign solitary fibrous tumor of the pleura. The hilum overlay sign is an imaging appearance on chest radiographs in which the outline of the hilum can be seen at the level of a mass or collection in the mid chest. It implies that the mass is not in the middle mediastinum, and is either from anterior or posterior mediastinum(most of the masses arise from the anterior mediastinum).

Incomplete lacerations may require closer scrutiny to detect and may not be diagnosed right away. Bronchial injuries are divided into those that are accompanied by a disruption of the pleura and those that are not; in the former, air can leak from the hole in the airway and a pneumothorax can form. The latter type is associated with more minor signs; pneumothorax is small if it occurs at all, and although function is lost in the part of the lung supplied by the injured bronchus, unaffected parts of the lungs may be able to compensate. Most TBI that results from blunt trauma occurs within the chest.

"We probably will find out a lot more about the health aspects of asbestos from [the World Trade Center attack], unfortunately," said Dr. Alan Fein, chief of pulmonary and critical-care medicine at North Shore-Long Island Jewish Health System. Mesothelioma development in rats has been demonstrated following intra-pleural inoculation of phosphorylated chrysotile fibers. It has been suggested that in humans, transport of fibers to the pleura is critical to the pathogenesis of mesothelioma. This is supported by the observed recruitment of significant numbers of macrophages and other cells of the immune system to localized lesions of accumulated asbestos fibers in the pleural and peritoneal cavities of rats.

He described the omentum and its connections with the stomach, the spleen and the colon; gave the first correct views of the structure of the pylorus; observed the small size of the caecal appendix in man; gave the first good account of the mediastinum and pleura and the fullest description of the anatomy of the brain up to that time. He did not understand the inferior recesses, and his account of the nerves is confused by regarding the optic as the first pair, the third as the fifth, and the fifth as the seventh. In this work, Vesalius also becomes the first person to describe mechanical ventilation.Vallejo-Manzur F. et al.

Complications are not common but include infection, lung abscess, and bronchopleural fistula (a fistula between the pleural space and the bronchial tree). A bronchopleural fistula results when there is a communication between the laceration, a bronchiole, and the pleura; it can cause air to leak into the pleural space despite the placement of a chest tube. The laceration can also enlarge, as may occur when the injury creates a valve that allows air to enter the laceration, progressively expanding it. One complication, air embolism, in which air enters the bloodstream, is potentially fatal, especially when it occurs on the left side of the heart.

A left anterolateral thoracotomy is the common method of opening the chest, as it provides rapid access, can be easily extended into the right hemithorax, and provides access to most of the important anatomical structures during resuscitation including the aorta. First an incision is made along the fourth or fifth intercostal space (between the ribs), intercostal muscles and the parietal pleura are divided, and then the ribs are retracted to provide visualization. When the incision covers both the right and left hemithoraxes it is referred to as a "clamshell" thoracotomy. The clamshell thoracotomy is used when there is a right sided pulmonary or vascular injury, or when greater access or visualization is desired.

The intercostal nerves are part of the somatic nervous system, and arise from the anterior rami of the thoracic spinal nerves from T1 to T11. The intercostal nerves are distributed chiefly to the thoracic pleura and abdominal peritoneum and differ from the anterior rami of the other spinal nerves in that each pursues an independent course without plexus formation. The first two nerves supply fibers to the upper limb in addition to their thoracic branches; the next four are limited in their distribution to the walls of the thorax; the lower five supply the walls of the thorax and abdomen. The 7th intercostal nerve terminates at the xyphoid process, at the lower end of the sternum.

Myrmica laevinodis is a species of ant that closely resembles M. kotokui, and is at times difficult to distinguish, due to variation in morphology and color in M. kotokui. However, the unraised rugae on the posterodorsal portion of the mesonotum are usually characteristic, though some M. kotokui workers have this character. It is best in the field to examine the body coloration of a number of workers from each colony. Also, M. rubra has fewer strong rugae, and is more smooth on the lower half of the mesonotal pleura than M. kotokui; its propodeal spines are shorter, and the rugae on the anterior basal portion of the 1st gastral tergite are relatively weak and fewer in number.

In severe cases of fibrothorax that are compromising a person's ability to breathe, the scar tissue (fibrous peel) causing fibrothorax can be surgically removed using a technique called decortication. However, surgical decortication is an invasive procedure which carries the risk of complications including a small risk of death, and is therefore generally only considered if severe symptoms are present and have been for many months. Surgical decortication is generally considered for people with fibrothoraces that are severe, causing significant shortness of breath, and have otherwise relatively healthy lungs since this enhances the likelihood of a better outcome. Surgical removal of the pleura (pleurectomy) may be performed in refractory cases, as often happens when asbestosis is the cause.

After what was initially thought to be pneumonia, Ruby was diagnosed with cancer at Parkland in December 1966. Rose indicated that the same type of cancer that affected Ruby's lungs was found in his brain, lymph nodes, liver, pancreas, pleura, ribs, and vertebra. He said that eight tumors were found in his brain, with the largest being three-fourths of an inch. Rose told reporters that he could not definitively answer whether or not the tumors were present in Ruby's brain at the time he shot Oswald, but he indicated metastasis from the lungs to the brain could not have occurred prior to 1964 since X-rays at the county jail that year revealed that his lungs were clear.

In addition to the hygiene-dietetic treatment, which meant rest and nutritious food one also used pneumothorax as a treatment. Pneumothorax, also called atelectasis, collapse therapy or fumigation of a patient's lungs, meant to allow air into the pleura. The tuberculosis bacterias needed oxygen to survive. When you remove the oxygen the bacteria has difficulties to cope, the lung had a rest, and the patient was able to fight the TB. Dimitris Dalianis needed a pneumothorax machine pneumothorax machine but such was not to find on the entire island of Ikaria, Dimitris Dalianis managed to smuggle out a letter to his wife Mando Dalianis who were in Athens (and had not yet been imprisoned) to arrange that Dimitris Dalianis pneumothorax machine would be sent to the island.

LD is roughly defined as a locoregional tumor burden confined to one hemithorax that can be encompassed within a single, tolerable radiation field, and without detectable distant metastases beyond the chest or supraclavicular lymph nodes. A patient is assigned an ED stage when the tumor burden is greater than that defined under LD criteria — either far advanced locoregional disease, malignant effusions from the pleura or pericardium, or distant metastases. However, more recent data reviewing outcomes in very large numbers of SCLC patients suggests that the TNM staging system used for NSCLC is also reliable and valid when applied to SCLC patients, and that more current versions may allow better treatment decisionmaking and prognostication in SCLC than with the old dichotomous staging protocol.

The Warren Report itself does not conclude bullet entry at the sixth cervical vertebra, but this conclusion was made in a 1979 report on the assassination by the HSCA, which noted a defect in the C6 vertebra in the Bethesda X-rays, which the Bethesda autopsy physicians had missed and did not note. The X-rays were taken by US Navy Medical Corps Commander John H. Ebersole. Even without any of this information, the original Bethesda autopsy report, included in the Warren Commission report, concluded that this bullet had passed entirely through the President's neck, from a level over the top of the scapula and lung (and the parietal pleura over the top of the lung) and through the lower throat.

The mesothelium consists of a single layer of flattened to cuboidal cells forming the epithelial lining of the serous cavities of the body including the peritoneal, pericardial and pleural cavities. Deposition of asbestos fibers in the parenchyma of the lung may result in the penetration of the visceral pleura from where the fiber can then be carried to the pleural surface, thus leading to the development of malignant mesothelial plaques. The processes leading to the development of peritoneal mesothelioma remain unresolved, although it has been proposed that asbestos fibers from the lung are transported to the abdomen and associated organs via the lymphatic system. Additionally, asbestos fibers may be deposited in the gut after ingestion of sputum contaminated with asbestos fibers.

Restrictive lung disease is characterized by reduced lung volumes, and therefore reduced lung compliance, either due to an intrinsic reason, for example a change in the lung parenchyma, or due to an extrinsic reason, for example diseases of the chest wall, pleura, or respiratory muscles. Generally, intrinsic causes are from lung parenchyma diseases that cause inflammation of scarring of the lung tissue, such as interstitial lung disease or pulmonary fibrosis, or from having the alveoli air spaces filled with external material such as debris or exudate in pneumonitis. As some diseases of the lung parenchyma progress, the normal lung tissue can be gradually replaced with scar tissue that is interspersed with pockets of air. This can lead to parts of the lung having a honeycomb-like appearance.

He declined suggestions to go to the hospital and instead delivered his scheduled speech with blood seeping into his shirt. His opening comments to the gathered crowd were, "Ladies and gentlemen, I don't know whether you fully understand that I have just been shot, but it takes more than that to kill a bull moose." He spoke for 90 minutes before completing his speech and accepting medical attention.. Afterwards, probes and an x-ray showed that the bullet had lodged in Roosevelt's chest muscle, but did not penetrate the pleura. Doctors concluded that it would be less dangerous to leave it in place than to attempt to remove it, and Roosevelt carried the bullet with him for the rest of his life.

The costocervical trunk arises from the upper and back part of the second part of subclavian artery, behind the scalenus anterior on the right side, and medial to that muscle on the left side. Passing backward, it splits into the deep cervical artery and the superior intercostal artery (highest intercostal artery), which descends behind the pleura in front of the necks of the first and second ribs, and anastomoses with the first aortic intercostal (3rd posterior intercostal artery). As it crosses the neck of the first rib it lies medial to the anterior division of the first thoracic nerve, and lateral to the first thoracic ganglion of the sympathetic trunk. In the first intercostal space, it gives off a branch which is distributed in a manner similar to the distribution of the aortic intercostals.

The program is the largest of its kind and attracts patients from all over the world. Sugarbaker arrived at the Texas Medical Center (TMC) in 2014 and that same year founded the new Division of General Thoracic Surgery, the Lung Institute, which integrates medical and surgical treatments for benign and malignant non- cardiac thoracic diseases, and the Mesothelioma Treatment Center (MTC), focused on the evaluation and treatment of patients with mesothelioma. As Director of the Baylor College of Medicine Lung Institute at CHI St. Luke's Health–Baylor St. Luke's Medical Center, Sugarbaker led the first multi- specialty Lung Institute in Texas, focused on the treatment of lung disease. Sugarbaker's clinical practice was focused in general thoracic surgery, specifically the surgical treatment of benign and malignant disorders of the lung, pleura, esophagus, chest wall, and mediastinum.

At the union of the ascending aorta with the aortic arch the caliber of the vessel is increased, owing to a bulging of its right wall. This dilatation is termed the bulb of the aorta, and on transverse section presents a somewhat oval figure. The ascending aorta is contained within the pericardium, and is enclosed in a tube of the serous pericardium, common to it and the pulmonary artery. The ascending aorta is covered at its commencement by the trunk of the pulmonary artery and the right auricula, and, higher up, is separated from the sternum by the pericardium, the right pleura, the anterior margin of the right lung, some loose areolar tissue, and the remains of the thymus; posteriorly, it rests upon the left atrium and right pulmonary artery.

Various styles of mouthpiece are available off the shelf or as customised items, and one of them may work better if either of these problems occur. The frequently quoted warning against holding one's breath on scuba is a gross oversimplification of the actual hazard. The purpose of the admonition is to ensure that inexperienced divers do not accidentally hold their breath while surfacing, as the expansion of gas in the lungs could over-expand the lung air spaces and rupture the alveoli and their capillaries, allowing lung gases to get into the pulmonary return circulation, the pleura, or the interstitial areas near the injury, where it could cause dangerous medical conditions. Holding the breath at constant depth for short periods with a normal lung volume is generally harmless, providing there is sufficient ventilation on average to prevent carbon dioxide buildup, and is done as a standard practice by underwater photographers to avoid startling their subjects.

This was in stark contrast to many of the anatomical models used previously, which had strong Galenic/Aristotelean elements, as well as elements of astrology. Besides the first good description of the sphenoid bone, he showed that the sternum consists of three portions and the sacrum of five or six; and described accurately the vestibule in the interior of the temporal bone. He not only verified the observation of Etienne on the valves of the hepatic veins, but he described the vena azygos, and discovered the canal which passes in the fetus between the umbilical vein and the vena cava, since named ductus venosus. He described the omentum, and its connections with the stomach, the spleen and the colon; gave the first correct views of the structure of the pylorus; observed the small size of the caecal appendix in man; gave the first good account of the mediastinum and pleura and the fullest description of the anatomy of the brain yet advanced.
