The problem was, that while she was going through the stem cell transplant, she developed V.O.D. (Veno-Occlusive Disease).
|
|
Using a rich moisturizer will create a temporary occlusive seal to keep the heat trapped in the skin, which for extraction purposes, is necessary.
|
|
"We don't totally understand why they occur, but it is thought that sun damage and occlusive cosmetics predispose people to develop milia," he says.
|
|
To relieve them, Dr. Zeichner suggests applying an occlusive ointment anywhere on or between the cheeks and outside the anus, like Aveeno Cracked Skin Relief Cica Ointment.
|

Red, Inflamed NoseWhen you've blown your nose raw (it happens), you'll find instant relief from occlusive moisturizers, which form a film on the skin to keep pollen and allergens out.
|
|
This last part's occlusive: It seals in all the previous steps' nutrients, and then I'm safe for about 12 hours, after which I'll have to do it all over again.
|
|
Cue a number of people shelling out on expensive facial oils and occlusive moisturizers to counteract the shine — only to find their skin is getting oilier or breaking out. Confused?
|
|
"Although [they are] likely less occlusive and more lightweight…the skin is still a sensitive organ that needs to interact with the surrounding environment to do its job," says Dr. Nazarian.
|
|
Now that it's officially time to put the jars of occlusive balms and multi-purpose butters (far, far) away, you've got to set a game plan for your summer-friendly skin routine.
|
|
When used together, an occlusive moisturizer will help lock in the additional hydration from the hyaluronic acid, instead of letting it escape and take more of your skin's water along with it.
|
|
An occlusive forms a physical barrier, no matter how imperceptible, over your skin (like an oil or a silicone), while an emollient is actually more of a skin-softener than a skin hydrator.
|
|
As dermatologist Doris Day, MD, explains, skin tends to be better able to hydrate itself naturally in the summer than in the winter, so your heavy, occlusive moisturizers can be just that: too heavy.
|
|
Armed with a set of military-grade response skills unusual for a paramedic, Mr. Shade rapidly applied HyFin occlusive chest seals, commonly used by medics in war, to block airflow into Mr. Mika's body.

"As dysfunction of the vascular endothelium is central to the pathogenesis of vascular disease, such adverse arterial effects could lead to the development of occlusive arterial diseases, including myocardial infarction and stroke," Delp and co. write.
|
|
Coconut oil already comes with a few caveats: For example, people with acne-prone skin are advised to steer clear, as coconut oil is an occlusive moisturizer that can clog the pores, aggravating breakouts in the process.
|
|
And it's not just your makeup bag that may need an overhaul: Dr. Zeichner says that rich, occlusive skin-care products, including eye creams, can also lead to milia forming near the eyes and on the cheeks.
|
|
"As mindful as you're being about the makeup you're not putting on your skin, you should be likewise aware of heavy, occlusive creams you're wearing," Dr. Nussbaum explains — meaning, a moisturizer that may be clogging your pores.
|
|
Unlike your run-of-the-mill mask, though, patches create a truly occlusive barrier on the skin that "pushes" active ingredients into the skin, which holds in moisture, eliminates the issue of evaporation, and makes them much more potent.
|
|
Its thicky, goopy texture lends the same consistency as a vat of Vaseline, but unlike petroleum jelly, "lanolin forms a non-occlusive barrier between the skin and outside factors, like wind or moisture, so the skin can still breathe through it," explains aesthetic plastic surgeon Paul Lorenc, MD, FACS.

CT angiography would be helpful in differentiating occlusive from non-occlusive causes of mesenteric ischaemia.
|
|
Lidocaine/prilocaine eutectic mixture is marketed as a 5% oil-in-water emulsion incorporated in a cream base (EMLA cream) or a cellulose disk (EMLA patch). The cream is applied under an occlusive dressing, while the patch incorporates an occlusive dressing to facilitate absorption of lidocaine and prilocaine into the area where anaesthesia is required. Local dermal anaesthesia is achieved after approximately 60 minutes, whereupon the occlusive dressing (or patch) is removed. The duration of anaesthesia is approximately two hours following removal of the occlusive dressing.

Topical anaesthetics are used under adhesive occlusive dressings in children before venesection.
|
|
Non-occlusive disease has a poor prognosis with survival rate between 40-50%.

|
Either "occlusive" or "stop" may be used as a general term covering the other together with nasals. That is, 'occlusive' may be defined as oral occlusive (plosives and affricates) plus nasal occlusives (nasals such as , ), or 'stop' may be defined as oral stops (plosives) plus nasal stops (nasals). Ladefoged and Maddieson (1996) prefer to restrict 'stop' to oral non-affricated occlusives. They say, :what we call simply nasals are called nasal stops by some linguists.

Autolysis uses the body's own enzymes and moisture to re-hydrate, soften and finally liquefy hard eschar and slough. Autolytic debridement is selective; only necrotic tissue is liquefied. It is also virtually painless for the patient. Autolytic debridement can be achieved with the use of occlusive or semi-occlusive dressings which maintain wound fluid in contact with the necrotic tissue.
|
|
Pulmonary veno-occlusive disease may have a genetic basis, published reports have indicated fatal occurrences that appeared to possess a familial pattern, more to the point, a germline mutation. The pathophysiology of veno-occlusive disease culminates in occlusion of the pulmonary blood vessels. This could be due to edematous tissue (sclerotic fibrous tissue). Thickening is identified in lobular septal veins, also dilatation of lymphatics happens.
|
|
Steroid-induced atrophy It can also present with telangiectasia, easy bruising, purpura, and striae. Occlusive dressings and fluorinated steroids both increase the likelihood of developing atrophy.
|
|
Acute chest syndrome is defined by at least two of these signs or symptoms: chest pain, fever, pulmonary infiltrate or focal abnormality, respiratory symptoms, or hypoxemia. It is the second-most common complication and it accounts for about 25% of deaths in patients with SCD. Most cases present with vaso-occlusive crises, and then develop acute chest syndrome. Nevertheless, about 80% of people have vaso- occlusive crises during acute chest syndrome.
|
|
In phonetics, a nasal, also called a nasal occlusive or nasal stop in contrast with an oral stop or nasalized consonant, is an occlusive consonant produced with a lowered velum, allowing air to escape freely through the nose. The vast majority of consonants are oral consonants. Examples of nasals in English are , and , in words such as nose, bring and mouth. Nasal occlusives are nearly universal in human languages.
|
|
For more severe crises, most patients require inpatient management for intravenous opioids. Extra fluids, administered either orally or intravenously, are a routine part of treatment of vaso-occlusive crises but the evidence about the most effective route, amount and type of fluid replacement remains uncertain. Crizanlizumab, a monoclonal antibody target towards p-selectin was approved in 2019 in the United States to reduce the frequency of vaso-occlusive crisis in those 16 years and older.
|
|
Crizanlizumab is a monoclonal antibody against P-selectin. which has now been approved by Novartis on November 15, 2019 for the indication of vaso- occlusive crisis in sickle cell patients.

Non-occlusive disease (NOD) or Non-occlusive mesenteric ischaemia (NOMI) is a life-threatening condition including all types of mesenteric ischemia without mesenteric obstruction. It affects mainly elderly patients above 50 years of age who suffer from cardiovascular disease (myocardial infarction, congestive heart failure or aortic regurgitation), hepatic, chronic kidney disease or diabetes mellitus. It can be triggered also by a previous cardiac surgery with a consequent heart shock. It represents around 20% of cases of acute mesenteric ischaemia.
|
|
Occlusive dressings come in various forms, including petrolatum gauze, which sticks to the skin surrounding the wound using petrolatum. They can also be used to enhance the penetration and absorption of topically-applied medications, such as ointments and creams. Furthermore, they may be used as part of in vivo acute toxicity tests of dermal irritation and sensitization. The test animal is shaved and the test material is applied to the skin and wrapped in an occlusive material.
|
|
Non-occlusive mesenteric ischemia occurs due to severe vasoconstriction of mesenteric vessels supplying the intestine. Acute abdominal pain is the only early acute symptom in those patients, which makes early diagnosis difficult.

|
This condition is inherited as an autosomal recessive pattern. It is characterized by generalized calcification of the arterial internal elastic lamina, leading to rupture of the lamina and occlusive changes in the tunica intima with stenosis and decreased elasticity of the vessel wall. Unfortunately, many infants die of vaso-occlusive disease, especially of the coronary arteries. There are 2 forms of GACI that can be indicated on a genetic test: GACI Type 1 is caused by mutations in the ENPP1 gene.
|
|
Pulmonary veno-occlusive disease can only be well diagnosed with a lung biopsy. CT scans may show characteristic findings such as ground-glass opacities in centrilobular distribution, and mediastinal lymphadenopathy, but these findings are non-specific and may be seen in other conditions. However, pulmonary hypertension (revealed via physical examination), in the presence of pleural effusion (done via CT scan) usually indicates a diagnosis of pulmonary veno-occlusive disease. The prognosis indicates usually a 2-year (24 month) life expectancy after diagnosis.
|
|
The genetic cause of pulmonary veno-occlusive disease is mutations in EIF2AK4 gene. Though this does not mean other possible causes do not exist, such as viral infection and risk of toxic chemicals (chemotherapy drugs).

Hepatic veno-occlusive disease or veno-occlusive disease with immunodeficiency (VODI) is a potentially life-threatening condition in which some of the small veins in the liver are obstructed. It is a complication of high-dose chemotherapy given before a bone marrow transplant (BMT) and/or excessive exposure to hepatotoxic pyrrolizidine alkaloids. It is classically marked by weight gain due to fluid retention, increased liver size, and raised levels of bilirubin in the blood. The name sinusoidal obstruction syndrome is preferred if VODI happens as a result of chemotherapy or bone marrow transplantation.

The primary purpose of lip balm is to provide an occlusive layer on the lip surface to seal moisture in lips and protect them from external exposure. Dry air, cold temperatures, and wind all have a drying effect on skin by drawing moisture away from the body. Lips are particularly vulnerable because the skin is so thin, and thus they are often the first to present signs of dryness. Occlusive materials like waxes and petroleum jelly prevent moisture loss and maintain lip comfort while flavorings, colorants, sunscreens, and various medicaments can provide additional, specific benefits.

The iliac veins (in the pelvis) include the external iliac vein, the internal iliac vein, and the common iliac vein. The common femoral vein is visible below the external iliac vein. (It is labeled simply "femoral" here.) Provoked DVTs occur in association with acquired risk factors, such as surgery, oral contraceptives, trauma, immobility, obesity, or cancer; cases without acquired states are called unprovoked or idiopathic. Acute DVT is characterized by pain and swelling and is usually occlusive, which means that it obstructs blood flow, whereas non-occlusive DVT is less symptomatic.

Crizanlizumab, (brand name Adakveo), is a monoclonal antibody developed by Novartis targeted towards P-selectin. It was announced by the company as an effective drug to prevent vaso-occlusive crisis in patients with sickle cell anemia. The result of the Phase II SUSTAIN clinical trial was published in December 2016. Crizanlizumab is a treatment to reduce the frequency of vaso- occlusive crisis – a common and painful complication of sickle cell disease that occurs when blood circulation is obstructed by sickled red blood cells – for those 16 years and older.

|
The acute chest syndrome is a vaso-occlusive crisis of the pulmonary vasculature commonly seen in people with sickle cell anemia. This condition commonly manifests with a new opacification of the lung(s) on a chest x-ray.
|
|
The terms stop, occlusive, and plosive are often used interchangeably. Linguists who distinguish them may not agree on the distinction being made. The terms refer to different features of the consonant. "Stop" refers to the airflow that is stopped.
|
|
As a result, during periods of low blood pressure, the arteries feeding the colon clamp down vigorously; a similar process can result from vasoconstricting drugs such as ergotamine, cocaine, or vasopressors. This vasoconstriction can result in non-occlusive ischemic colitis.
|
|
Though early use focused on burns and surgical wounds, wider use of wounds treated with TCOT have become more common in diabetic foot ulcers, venous stasis and decubitus ulcers(pressure sores). TCOT involves inserting a thin tube which delivers the oxygen above the wound bed of a cleaned wound. An absorbent dressing is then placed above the tube and an occlusive or semi occlusive dressing is placed over the entire wound site. The far end of the tube is connected to an oxygen delivery unit, often portable, which delivers oxygen at a slow rate, typically 3ml per hour.

In his Presidential Address to the Society of Vascular Surgery annual meeting in 1995, Rutherford emphasized the importance of uniform disease-specific reporting standards for describing vascular interventions, their results, and their complications. Rutherford organized the Society of Vascular Surgery committees that developed the current reporting standards, an initiative that expanded globally when he co-chaired the first TransAtlantic Consensus on Peripheral Arterial Occlusive Disease, in 2000. He also co- chaired the Transatlantic Consensus on Peripheral Arterial Occlusive Disease (TASC) in 2005. That same year, he was the recipient of the first Lifetime Achievement Award given by the Society of Vascular Surgery.

Diprobase is an emollient, specifically targeted at eczema and dermatitis. It is an occlusive emollient, meaning that it restores the layer of oil on the surface of the skin to slow water loss. This gives its tendency to make the applied area sticky.
|
|
Treatment is the same as for patients with sickle cell disease. Patients may receive hydroxyurea to induce the protective effects of increased fetal hemoglobin production. They may also benefit from blood transfusions especially during vaso-occlusive crises. Patients may be offered chemoprophylaxis with penicillin.
|
|
Egg oil can be used as an excipient/carrier in a variety of cosmetic preparations such as creams, ointments, sun-screen products, treatment of sunburn or lotions where it acts as an emollient, moisturizer, anti-oxidant, penetration enhancer, occlusive skin conditioner and anti-bacterial agent.
|
|
Under open treatment, little substance reaches the circulation, and the body's own blood corticoid (cortisol) levels are not influenced. Under occlusive therapy, cortisol levels can be decreased because of a feedback reaction via the hypothalamic–pituitary–adrenal axis. This reaction is however not clinically significant.
|
|
Symptoms of VOD include weight gain, elevated bilirubin, painful hepatomegaly, and edema. The reason busulfan causes VOD is mostly unknown and can be deadly. Ursodiol may be considered for prophylaxis of veno-occlusive disease. Antiemetics are often administered prior to busulfan to prevent vomiting (emesis).

Most cases of erectile dysfunction of organic causes are related to changes in blood flow in the corpora cavernosa, represented by occlusive artery disease, most often of atherosclerotic origin, or due to failure of the veno-occlusive mechanism. Preceding the ultrasound examination with Doppler, the penis must be examined in B mode, in order to identify possible tumors, fibrotic plaques, calcifications, or hematomas, as well as to evaluate the appearance of the cavernous arteries, which can be tortuous or atheromatous. Figure 8 Transverse ultrasound image, ventral view of the penis. Image obtained after induction of an erection, 15 min after injection of prostaglandin E1, showing dilated sinusoids (arrows).

In one, coltsfoot tea causing severe liver problems in an infant was actually the result of Adenostyles alliariae (alpendost).Sperl, W., Stuppner, H., Gassner, I.; "Reversible hepatic veno-occlusive disease in an infant after consumption of pyrrolizidine-containing herbal tea." Eur. J. Pediatr. 1995;154:112–6.
|
|
As the agents differ in size, occlusive properties and side effect profiles, the choice of agent will also depend on the anatomy and locations of the tumors in a specific case. Some commonly used agents include cyanoacrylate, sodium tetradecyl sulfate foam, gelatin, metallic spherical particles, coils and absolute alcohol.

Sometimes a patient's history and clinical signs suggest a very high risk of stroke. Occlusive stroke causes permanent tissue damage over the following three hours (maybe even 4.5 hoursDeNoon, Daniel J. (2009). Immediate Treatment Best, but Even Late Treatment with tPA May Help. WebMD Health News.), but not instantly.

The first report on veno-occlusive disease, in 1920, was as a result of senecio poisoning in South Africa. Subsequent reports were mostly in Jamaicans who had consumed herbal teas. With the advent of bone marrow transplantation, most cases since its introduction have been in those undergoing treatment for leukemia.
|
|
Diagnosis of vaso-occlusive crisis is based on clinical manifestations, complete blood count with white blood cell differential, platelet count, reticulocyte count, and comprehensive metabolic panel with liver and kidney function tests. Typical lab findings include acute drop in hemoglobin concentration, increased platelet count, increased reticulocyte count, and elevated serum urea.

Occlusive dressings at night may be useful. Some moisturizers or barrier creams may reduce irritation in occupational irritant hand dermatitis, a skin disease that can affect people in jobs that regularly come into contact with water, detergents, chemicals or other irritants. Some emollients may reduce the number of flares in people with dermatitis.

Flunarizine is effective in the prophylaxis of migraine, occlusive peripheral vascular disease, vertigo of central and peripheral origin, and as an add-on in the treatment of epilepsy where its effect is weak and not recommended. It has been shown to significantly reduce headache frequency and severity in both adults and children.
|
|
More than 100 years ago a German pathologist named Rudolf Virchow discovered that cholesterol was to be found in the artery walls of people that died from occlusive vascular diseases, like myocardial infarction. The cholesterol was found to be responsible for the thickening of the arterial walls and thus decreasing the radius in the arteries which leads in most cases to hypertension and increased risk of occlusive vascular diseases. In the 1950s the Framingham heart study led by Dawber revealed the correlation between high blood cholesterol levels and coronary heart diseases. Following up from that study the researchers explored a novel way to lower blood cholesterol levels without modifying the diet and lifestyle of subjects suffering with elevated blood cholesterol levels.

Wound myiasis occurs when fly larvae infest open wounds. It has been a serious complication of war wounds in tropical areas, and is sometimes seen in neglected wounds in most parts of the world. Predisposing factors include poor socioeconomic conditions, extremes of age, neglect, mental disability, psychiatric illness, alcoholism, diabetes, and vascular occlusive disease.

Urinary incontinence and gait apraxia are also not uncommon findings. Of note, occlusive damage to Heubner's artery may also present with contralateral grip reflex issues, and symptoms of frontal lobe disorder. Contralateral gaze preference with or without transcortical motor aphasia may present in instances where the left hemisphere is affected in this type of occlusion.
|
|
PAs also cause hepatic veno-occlusive disease and liver cancer. PAs are tumorigenic. Disease associated with consumption of PAs is known as pyrrolizidine alkaloidosis. Of concern is the health risk associated with the use of medicinal herbs that contain PAs, notably borage leaf, comfrey and coltsfoot in the West, and some Chinese medicinal herbs.

The stem pessary, a type of occlusive pessary, was an early form of the cervical cap. Shaped like a dome, it covered the cervix, and a central rod or "stem" entered the uterus through the external orifice of the uterus, also known as the cervical canal or the os, to hold it in place.
|
|
"Occlusive" refers to the articulation, which occludes (blocks) the vocal tract. "Plosive" refers to the release burst (plosion) of the consonant. Some object to the use of "plosive" for inaudibly released stops, which may then instead be called "applosives". The International Phonetic Association and the International Clinical Phonetics and Linguistics Association use the term "plosive".
|
|
This theory proposes how high pulmonary venous pressures may lead to the capillary rupture and the tissue changes observed in EIPH. Regional veno- occlusive remodeling, especially within the caudodorsal lung fields, contributes to the pathogenesis of EIPH, with the venous remodeling leading to regional vascular congestion and hemorrhage, hemosiderin accumulation, fibrosis, and bronchial angiogenesis.
|
|
If carotid occlusive disease results in ophthalmic artery occlusion, general ocular ischemia may result in retinal neovascularization, rubeosis iridis, cells and flare, iris necrosis, and cataract. The condition leads to neovascularization in various eye tissues due to the ischemia. The eye pressure may become high due to associated neovascular glaucoma. An ischemic optic neuropathy may eventually occur.
|
|
It also has a unique carbohydrate moiety and a unique repetitive amino acid sequence which give it a high affinity for bonding to adhering proteins resulting in a tightening, anti-wrinkle effect. In addition, because of its high molecular weight, it leaves a substantive semi-occlusive film that persists even after washing, and can increase the skins permeability.
|
|
A sympathectomy is an irreversible procedure during which at least one sympathetic ganglion is removed. One example is the lumbar sympathectomy, which is advised for occlusive arterial disease in which L2 and L3 ganglia along with intervening sympathetic trunk are removed leaving behind the L1 ganglion which is responsible for ejaculation. Another example is endoscopic thoracic sympathectomy.
|
|
Subsequently, a crust appears over the entire tattoo, which sloughs off at approximately two weeks post-treatment. As noted above, some tattoo pigment may be found within this crust. Post-operative wound care consists of simple wound care and a non-occlusive dressing. Since the application of laser light is sterile there is no need for topical antibiotics.
|
|
Acrocyanosis is diagnosed clinically, based on a medical history and physical examination; laboratory studies or imaging studies are not necessary. The normal peripheral pulses rule out peripheral arterial occlusive disease, where arterial narrowing limits blood flow to the extremities. Pulse oximetry will show a normal oxygen saturation. Unlike the closely related Raynaud's phenomenon, cyanosis is continually persistent.
|
|
Severe liver injury can result from hepatic veno-occlusive disease (VOD), newly termed sinusoidal obstruction syndrome (SOS). Elevated levels of bilirubin, hepatomegaly, and fluid retention are clinical hallmarks of this condition. The appreciation of the generalized cellular injury and obstruction in hepatic vein sinuses is now greater. Severe cases of SOS are associated with a high mortality rate.
|
|
Side effects are rare and include typical corticoid reactions such as skin atrophy, telangiectasias, stretch marks, and steroid acne. They mostly occur when large skin areas (more than 10% of body surface) are treated, when treatment is continued over more than two to four weeks, under occlusive therapy or therapy in skin folds. Hypersensitivity reactions have also been described.

Clocortolone pivalate 0.1% is formulated in a cream that contains three ingredients which assist in stratum corneum permeability barrier integrity: white petrolatum (occlusive), mineral oil (humectant), and stearyl alcohol (long-chain fatty alcohol emollient). This cream does not contain lanolin, fragrance, nor propylene glycol, all of which have been known to be problematic for some patients.
|
|
The accelerated approval was based on the surrogate endpoint of response rate. It was the first antibody-drug conjugate to be approved. Within the first year after approval, the FDA required a black box warning be added to gemtuzumab packaging. The drug was noted to increase the risk of veno-occlusive disease in the absence of bone marrow transplantation.
|
|
Urea-containing creams are used as topical dermatological products to promote rehydration of the skin. Urea 40% is indicated for psoriasis, xerosis, onychomycosis, ichthyosis, eczema, keratosis, keratoderma, corns, and calluses. If covered by an occlusive dressing, 40% urea preparations may also be used for nonsurgical debridement of nails. Urea 40% "dissolves the intercellular matrix" of the nail plate.
|
|
Several symptoms are related to the tested exposure to benzotrichloride (BTC) in rats: irritation of the eyes, the skin and the respiratory tract. Under occlusive conditions, rabbit skin which was exposed to BTC showed irritation. Next, severe eye irritation was reported in rabbits, after administering 0.1 mL of BTC. This eye irritation lasted up to 7 days.

A rare and massive DVT that causes significant obstruction is phlegmasia cerulea dolens, so named because of observed cases with a blue or purplish discoloration. It is a particularly severe form of acute, proximal, and occlusive DVT. It is life-threatening, limb-threatening, and carries a risk of venous gangrene. It can occur in the arm but more commonly affects the leg.
|
|
Occlusive pessaries are most commonly used for contraception. Also known as a contraceptive cap, they work similar to a diaphragm as a barrier form of contraception. It is inserted into the vagina and blocks sperm from entering to the uterus through the cervix. The cap must be used in conjunction with a spermicide in order to be effective in preventing pregnancy.
|
|
For more severe crises, most patients require inpatient management for intravenous opioids; patient-controlled analgesia devices are commonly used in this setting. Vaso-occlusive crisis involving organs such as the penis or lungs are considered an emergency and treated with red blood cell transfusions. Incentive spirometry, a technique to encourage deep breathing to minimise the development of atelectasis, is recommended.
|
|
Most people with sickle cell disease have intensely painful episodes called vaso-occlusive crises. However, the frequency, severity, and duration of these crises vary tremendously. Painful crises are treated symptomatically with pain medications; pain management requires opioid drug administration at regular intervals until the crisis has settled. For milder crises, a subgroup of patients manages on NSAIDs (such as diclofenac or naproxen).
|
|
A medication's potency often is changed with its base. For example, some topical steroids will be classified one or two strengths higher when moving from cream to ointment. As a rule of thumb, an ointment base is more occlusive and will drive the medication into the skin more rapidly than a solution or cream base.Wolverton, SE. Comprehensive Dermatologic Drug Therapy.
|
|
Results are not reliable when the patient is symptomless and must be checked carefully. For example, in high risk post-operative patients, mainly after orthopedic surgery where there is already lower limb pain and edema following surgery, thrombi can be localized in the calf veins and often these are not completely occlusive. In this situation a complete examination is mandatory.
|
|
Pitted keratolysis occurs worldwide and in various climates. The infection is more common in people who live in tropical climates and walk barefoot, and those who spend a lot of time wearing occlusive footwear (e.g., tight shoes, rubber boots), such as in the military where wet shoes are worn for a prolonged period of time without removing and proper hygiene.
|
|
0.1% Amcinonide cream or ointment is typically applied two to three times daily to treat dermatitis, psoriasis, and/ or eczema while the same strength lotion is usually only used twice daily. This information can be found on the FDA approved label or from the prescribing doctor or pharmacist. Occlusive dressings may be used to supplement Amcinonide treatment, particularly when treating psoriasis.

Ischemia or ischaemia is a restriction in blood supply to tissues, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive).Merck & Co. Occlusive Peripheral Arterial Disease, The Merck Manual Home Health Handbook website, revised and updated March 2010. Retrieved March 4, 2012. Ischemia is generally caused by problems with blood vessels, with resultant damage to or dysfunction of tissue.
|
|
There is an increased risk of infection with exposure to warm, moist environments (e.g., occlusive footwear—shoes or boots that enclose the feet) and in shared humid environments such as communal showers, shared pools, and treatment tubs. Chlorine bleach is a disinfectant and common household cleaner that kills mold. Cleaning surfaces with a chlorine bleach solution prevents the disease from spreading from subsequent contact.
|
|
Gastrointestinal bleeding is a rare symptom and usually involved bleeding from the stomach. In the circulatory system, intermittent claudication, a condition in which cramping pain in the leg is induced by exercise, is a prominent feature. At later stages, coronary artery disease may develop, leading to angina and myocardial infarction (heart attack) may occur. Cerebral ischemia in PXE is caused by small vessel occlusive disease.

Toxicity may include interstitial pulmonary fibrosis ("busulfan lung"), hyperpigmentation, seizures, hepatic (veno- occlusive disease) (VOD) or sinusoidal obstruction syndrome (SOS), emesis, and wasting syndrome. Busulfan also induces thrombocytopenia, a condition of lowered blood platelet count and activity, and sometimes medullary aplasia. Seizures and VOD are serious concerns with busulfan therapy and prophylaxis is often utilized to avoid these effects. Hepatic VOD is a dose-limiting toxicity.

Years of clinical study have confirmed the safety advantage of using urokinase. Consequently, urokinase has been preferentially used in deep venous thrombosis and peripheral arterial occlusive disease where it is administered directly to the site of the clot while tPA is preferred in AMI where peripheral bleeding is a secondary consideration. A revolutionary method for the production of urokinase was patented by Evelyn Nicol in 1976 (U.S. Patent No. 3,930,944).

The liver damage in both acute and chronic intoxication can cause hepatic veno-occlusive disease (VOS), signs and symptoms of which include nausea, vomiting, hepatomegaly, and bloody diarrhea. Additionally, acute intoxication can cause hemorrhagic necrosis and liver failure, with signs and symptoms including weight loss, jaundice, depression, behavior changes, and ascites. Photosensitive dermatitis may also be seen. Other symptoms and manifestations of chronic exposure include weakness, portal hypertension, and cirrhosis.

Nightingale enlisted in the British Army in 1995, and served in the Queen's Lancashire Regiment (later amalgamated into the Duke of Lancaster's Regiment). He served as a sergeant in the Special Air Service from 2001, undertaking tours of duty in Northern Ireland, Bosnia, Lebanon, Turkey, Iraq, Afghanistan, Syria and Libya. He helped develop the "Nightingale Dressing", a large occlusive dressing used in the management of penetrating chest trauma.

HSCT is associated with a high treatment-related mortality in the recipient, which limits its use to conditions that are themselves life-threatening. (The one- year survival rate has been estimated to be roughly 60%, although this figure includes deaths from the underlying disease, as well as from the transplant procedure.) Major complications include veno-occlusive disease, mucositis, infections (sepsis), graft-versus-host disease, and the development of new malignancies.

Pulmonary veno-occlusive disease (PVOD) is a rare form of pulmonary hypertension caused by progressive blockage of the small veins in the lungs. The blockage leads to high blood pressures in the arteries of the lungs, which, in turn, leads to heart failure. The disease is progressive and fatal, with median survival of about 2 years from the time of diagnosis to death. The definitive therapy is lung transplantation.

This results in a reduction of pain signals being transmitted throughout the nerves. The effects generally last for three to six months. Photo of Mathieu Jaboulay courtesy of Romain Rochefeuille Certain neurolysis techniques have been reported to be used in the early 1900s for the treatment of pain by the neurologist Mathieu Jaboulay. Early reported neurolysis helped treat vasospastic disorders such as arterial occlusive disease before the introduction of endovascular procedures.

Steroids may be administered via intravitreal injection to treat diabetic and vasculo-occlusive macular edema, exudative macular degeneration, pseudophakic cystoid macular edema, and posterior uveitis. Common steroids used to treat these conditions include dexamethasone and triamcinolone acetonide (Triescence, Alcon Laboratories, Inc.). Steroid implants, such as the dexamethasone implant (Ozurdex, Allergan, Inc.), are used for long-term treatment of macular edema. Both of these steroid work by modulating inflammatory cytokines.

Triluminal catheter The catheter is held in place by an adhesive dressing, suture, or staple which is covered by an occlusive dressing. Regular flushing with saline or a heparin-containing solution keeps the line open and prevents blood clots. There is no evidence that heparin is better than saline at preventing blood clots. Certain lines are impregnated with antibiotics, silver-containing substances (specifically silver sulfadiazine) and/or chlorhexidine to reduce infection risk.

Peripheral artery occlusive disease (obstruction of the arteries of the legs) occurs mainly in people with FH who smoke; this can cause pain in the calf muscles during walking that resolves with rest (intermittent claudication) and problems due to a decreased blood supply to the feet (such as gangrene). Atherosclerosis risk is increased further with age and in those who smoke, have diabetes, high blood pressure and a family history of cardiovascular disease.

It may or may not be waterproof; if it is airtight, the bandage is an occlusive dressing. The adhesive is commonly an acrylate, including methacrylates and epoxy diacrylates (which are also known as vinyl resins). The absorbent pad is often made of cotton, and there is sometimes a thin, porous-polymer coating over the pad, to keep it from sticking to the wound. The pad may also be medicated with an antiseptic solution.

The U.S. Food and Drug Administration (FDA) approved crizanlizumab based on evidence from one clinical trial (Trial 1/NCT01895361) of 132 patients with sickle cell diseases who had a history of vaso-occlusive crisis. The trial was conducted at 60 sites in the United States, Brazil and Jamaica. The FDA granted the application for crizanlizumab-tmca priority review, breakthrough therapy designation, and orphan drug designation. The FDA granted approval of Adakveo to Novartis.

In neurosurgery, excimer laser assisted non-occlusive anastomosis (ELANA) is a technique use to create a bypass without interrupting the blood supply in the recipient blood vessels. This reduces the risk of stroke or a rupture of an aneurysm. The ELANA technique is a subtle modification of other methods to establish a connection between blood vessels (anastomosis) to create a bypass in or to the brain. The differences involve how the recipient artery is opened.

A vaso-occlusive crisis is a common painful complication of sickle cell anemia in adolescents and adults. It is a form of sickle cell crisis. Sickle cell anemia – most common in those of African, Hispanic, and Mediterranean origin – leads to sickle cell crisis when the circulation of blood vessels is obstructed by sickled red blood cells, causing ischemic injuries. The most common complaint is of pain, and recurrent episodes may cause irreversible organ damage.

Amcinonide exhibits side effects common among other corticosteroids. While these reactions are uncommon for most delivery vehicles, the use of occlusive dressings increases the likelihood of such effects. These include burning, itching, skin dryness and irritation, acne/ pimples, skin atrophy, blistering, and/ or skin discoloration.Drugs.com: Amcinonide Topical While most side effects are mild, a medical professional should be contacted if severe rash, acne, skin deterioration, excessive hair growth, or abnormal weight gain occur.

Edward Bliss Foote designed an early form of barrier contraception that he called the "womb veil" The womb veil was a 19th-century American form of barrier contraception consisting of an occlusive pessary, i.e. a device inserted into the vagina to block access of the sperm into the uterus. Made of rubber, it was a forerunner to the modern diaphragm and cervical cap.Janet Farrell Brodie, Contraception and Abortion in Nineteenth-Century America (Cornell University Press, 1994), p.

The differential diagnosis includes several conditions that an experienced practitioner should be able to recognise and may require treatment distinct from the usual measures taken for miliaria. In most cases, the rash of miliaria will resolve without intervention. However, severe cases can last for weeks and cause significant disability. General measures should be recommended for all patients, including moving to an air-conditioned environment if possible, avoiding sweat-provoking activities and occlusive clothing, and taking frequent cool showers.

Lin has published more than 400 scholarly articles in scientific journals. He serves on the editorial boards or as a reviewer for many scientific journals. He has authored more than 60 book chapters and edited 3 vascular textbooks. His writing and speaking have focused on a range of subjects including endovascular treatment of aortic aneurysms, venous disease, endovascular treatment of lower extremity occlusive disease, experimental models of endovascular therapy, and thrombolysis in arterial and venous thrombosis research.

The method is now used worldwide in cardiology. The third major advance to which Forrester contributed came in the early 1990s: Forrester led a team that developed coronary angioscopy, a method for seeing inside a living patient's coronary arteries using a thin flexible fiberoptic catheter. His team discovered the presence of small, partially occlusive blood clots in patients with unstable angina (now called acute coronary syndrome), leading to the modern implementation of antiplatelet and anticoagulant therapy in this condition.

Pulmonary hypertension is a pathophysiologic condition with many possible causes. Indeed, this condition frequently accompanies severe heart or lung conditions. A 1973 World Health Organization meeting was the first attempt to classify pulmonary hypertension by its cause, and a distinction was made between primary PH (resulting from a disease of the pulmonary arteries) and secondary PH (resulting secondary to other, non-vascular causes). Further, primary PH was divided in the "arterial plexiform", "veno-occlusive" and "thromboembolic" forms.

The management of an acute event of vaso-occlusive crisis is the use of potent analgesics (opioids), rehydration with normal saline or Ringer's lactate, treatment of malaria (whether symptomatic or not) using artemisinin combination therapy, and the use of oxygen via face mask, especially for acute chest syndrome. Hyperbaric oxygen has also been shown to be a useful adjunct in pain reduction. Antibiotics may be utilized because patients usually have occult infection due to a "functional asplenia".

Pitted keratolysis (also known as Keratolysis plantare sulcatum, Keratoma plantare sulcatum, and Ringed keratolysis) is a bacterial skin infection of the foot. The infection is characterized by craterlike pits on the sole of the feet and toes, particularly weight bearing areas. The infection is caused by Corynebacterium species bacteria and Kytococcus sedentarius. Excessive sweating of the feet and use of occlusive footwear provide an environment in which these bacteria thrive and therefore increase the risk of developing pitted keratolysis.

Individuals with sickle cell–hemoglobin C (HbSC), have inherited the gene for sickle cell disease (HbS) from one parent and the gene for hemoglobin C disease (HbC) from the other parent. Since HbC does not polymerize as readily as HbS, there is less sickling in most cases. There are fewer acute vaso-occlusive events and therefore in some cases fewer sickle cell crises. The peripheral smear demonstrates mostly target cells and only a few sickle cells.

Furthermore, it would improve the social welfare of society at large, preventing overpopulation. After reading an article by on occlusive pessaries, Jacobs wrote to him, embarking on a lengthy correspondence. Convinced that diaphragms would help her patients, she performed a clinical trial across a mixed sampling of her clients. Finding the trial was successful, she introduced the method of birth control (still widely known to English speakers as the Dutch Cap) in the Netherlands and began counseling women on its use.

The nuclear vowels of nouns, verbs, and adjectives bear tone. Nukak has two tonemes (minimal pairs exist between them): high (H) and rising (LH). In the surface phonology there are also a low tone and a falling tone. The rising and falling tones are accompanied by lengthening of the vowel, however, the falling tone has been analyzed as actually being the allomorph of the high tone in closed syllables ending in or an occlusive consonant, except orin morpheme final open syllables.

Globally, fungal infections affect about 15% of the population and 20% of adults. Athlete's foot is common in individuals who wear unventilated (occlusive) footwear, such as rubber boots or vinyl shoes. Countries and regions where going barefoot is more common experience much lower rates of athlete's foot than do populations which habitually wear shoes; as a result, the disease has been called "a penalty of civilization". Studies have demonstrated that men are infected 2–4 times more often than women.

The vaso-occlusive crisis is caused by sickle-shaped red blood cells that obstruct capillaries and restrict blood flow to an organ, resulting in ischaemia, pain, necrosis, and often organ damage. The frequency, severity, and duration of these crises vary considerably. Painful crises are treated with hydration, analgesics, and blood transfusion; pain management requires opioid drug administration at regular intervals until the crisis has settled. For milder crises, a subgroup of patients manages on nonsteroidal anti-inflammatory drugs such as diclofenac or naproxen.

In the 1840s or 1860s E.B. Foote, a U.S. physician claims to have invented the cervical cap but it's reported that his patent was denied since the device could be used for obscene purposes. Foote claimed that his invention was "widely counterfeited". An occlusive pessary marketed in the United States as the "womb veil" seems to have been an early form of diaphragm or cervical cap.Janet Farrell Brodie, Contraception and Abortion in Nineteenth-Century America (Cornell University Press, 1994), p.

Macular telangiectasia type 2 (commonly referred to as MacTel) is more frequent than type 1 and generally affects both eyes (bilaterally). It usually affects both sexes equally. Type 3, also known as occlusive idiopathic juxtafoveolar retinal telangiectasia, is a rare, poorly understood neurological disease characterized by juxtafoveolar capillary occlusions in both eyes and capillary telangiectasia. Types of macular telangiectasia should not be confused with Age-related macular degeneration (AMD), from which it can be distinguished by symptoms, clinical features, pathogenesis, and disease management.

The technique of Lung transplant, the definitive therapy of PVOD. Treatments for primary pulmonary hypertension such as prostacyclins and endothelin receptor antagonists can be fatal in people with PVOD due to the development of severe pulmonary edema, and worsening symptoms after initiation of these medications may be a clue to the diagnosis of pulmonary veno occlusive disease. The definitive therapy is lung transplantation, though transplant rejection is always a possibility, in this measures must be taken in terms of appropriate treatment and medication.

In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases. The occlusion may be made with the tongue tip or blade (, ) tongue body (, ), lips (, ), or glottis (). Plosives contrast with nasals, where the vocal tract is blocked but airflow continues through the nose, as in and , and with fricatives, where partial occlusion impedes but does not block airflow in the vocal tract.
|
|
Simple nasals are differentiated from plosives only by a lowered velum that allows the air to escape through the nose during the occlusion. Nasals are acoustically sonorants, as they have a non-turbulent airflow and are nearly always voiced, but they are articulatorily obstruents, as there is complete blockage of the oral cavity. The term occlusive may be used as a cover term for both nasals and plosives. A prenasalized stop starts out with a lowered velum that raises during the occlusion.

The left lateral decubitus position also prevents the air from passing through a potentially patent foramen ovale (present in as many as 30% of adults) and entering the left ventricle, from which it could then embolise to distal arteries (potentially causing occlusive symptoms such as stroke).Brunicardi, F. Schwartz's Principles of Surgery, 9th Ed, McGraw Hill, 2009. p. 144 Administration of high percentage oxygen is recommended for both venous and arterial air embolism. This is intended to counteract ischaemia and accelerate bubble size reduction.

There are two types of vas-occlusive plugs: injectable plugs and non-injectable plugs. Injection of medical polyurethane (MPU) to form a plug in the vas deferens resulted in azoospermia in 96% of men, though these result were seen 24 months after injection. Studies on over 130 men following removal of the plug within five years showed successful restoration of fertility. The Shug, short for "silicon plug", is an example of a non-injectable plug, though there is little to no research on the Shug following 2008.

An occlusive dressing is an air- and water-tight trauma medical dressing used in first aid. These dressings are generally made with a waxy coating so as to provide a total seal, and as a result do not have the absorbent properties of gauze pads. They are typically used to treat open, or "sucking," chest wounds (open pneumothorax) to alleviate or prevent a tension pneumothorax (a serious complication of a simple pneumothorax). They are also used in conjunction with a moist sterile dressing for intestinal evisceration.

The peculiar shape of their last lower premolar is their most outstanding feature. These teeth were larger and more elongated than the other cheek-teeth and had an occlusive surface forming a serrated slicing blade. Though it can be assumed that this was used for crushing seeds and nuts, it is believed that most small multituberculates also supplemented their diet with insects, worms, and fruits. Tooth marks attributed to multituberculates are known on Champsosaurus fossils, indicating that at least some of these mammals were scavengers.

The major concern that has inhibited the use of thioguanine has been veno-occlusive disease (VOD) and its histological precursor nodular regenerative hyperplasia (NRH). The incidence of NRH with thioguanine was reported as between 33–76%. The risk of ensuing VOD is serious and frequently irreversible so this side effect has been a major concern. However, recent evidence using an animal model for thioguanine- induced NRH/VOD has shown that, contrary to previous assumptions, NRH/VOD is dose dependent and the mechanism for this has been demonstrated.

Atherosclerotic restriction to the arterial supply in peripheral artery occlusive disease may result in painful arterial ulcers of the ankle and foot, or give rise of gangrene of the toes and foot. Immobility of a person may result in prolonged pressure applied to the heels causing pressure sores. Impaired venous drainage from the foot in varicose veins may sequentially result in brown haemosiderin discolouration to the ankle and foot, varicose stasis dermatitis and finally venous ulcers. Other disorders of the foot include osteoarthritis of the joints, peripheral neuropathy and plantar warts.

While there are commonalities in the mode of action for urokinase and tPA, urokinase has some advantages for treatment of peripheral clots (Pulmonary Embolism, Deep Vein Thrombosis, Peripheral arterial occlusive disease). Unlike tPA, which is activated by binding to the fibrin within clots, urokinase is not sequestered by fibrin and therefore does not specifically attack hemostatic clots. This makes urokinase less likely to break down such hemostatic clots that are essential for ongoing blood vessel repair throughout the body. Dissolution of these “good” clots can lead to serious adverse events through hemorrhagic bleeding.

The cause of death was occlusive coronary atherosclerosis. Finger had suffered three heart attacks, in 1963, 1970 and 1973. Although it was long believed by Sinclair, and others, that Finger was buried in an unmarked potter's field grave, his body was actually claimed by his son, Fred, who honored his wish to be cremated, and via and spread his ashes in the shape of a bat on a beach in Oregon. The first story of the issue Batman #259 in December 1974 would be dedicated to Finger's memory.

In addition to the risk of causing birth defects and of causing liver damage, bosentan has a high risk of causing edema, pulmonary veno-occlusive disease, decreasing sperm counts, and decreases in hemoglobin and hematocrit. Very common adverse effects (occurring in more than 10% of people) include headache, elevated transaminases, and edema. Common adverse effects (between 1% and 10% of people) include anemia, reduced hemoglobin, hypersensitivity reactions, skin inflammation, itchiness, rashes, red skin, flushing, fainting, heart palpitations, low blood pressure, nasal congestion, gastro-esophageal reflux disease, and diarrhea.

The terms "sickle cell crisis" or "sickling crisis" may be used to describe several independent acute conditions occurring in patients with SCD, which results in anaemia and crises that could be of many types, including the vaso-occlusive crisis, aplastic crisis, sequestration crisis, haemolytic crisis, and others. Most episodes of sickle cell crises last between five and seven days. "Although infection, dehydration, and acidosis (all of which favor sickling) can act as triggers, in most instances, no predisposing cause is identified."Kumar, Vinay; Abbas, Abul K.; Fausto, Nelson; Aster, Jon (2009-05-28).

In the northwest, it is present to some extent in Versilia. In the east, it extends over the Pratomagno to include Bibbiena and its outlying areas, where are sometimes affected, both fully occlusive and lenited (lax, unvoiced) allophones being the major alternates. The Apennine Mountains are the northern border of the phenomenon, and while a definite southern border has not been established, it is present in Siena and further south to at least San Quirico d'Orcia. In the far south of Tuscany, it gives way to the lenition (laxing) typical of northern and coastal Lazio.

Lumbar sympathetic neurolysis is typically used on patients with ischemic rest pain, generally associated with nonreconstructable arterial occlusive disease. Although the disease is the basis for this type of neurolysis, other diseases such as peripheral neuralgia or vasospastic disorders can receive lumbar sympathetic neurolysis for pain treatment. Magnetic Resonance Image of Lumbar Spine courtesy of Nevit Dilmen Lumbar sympathetic neurolysis is performed between the L1-L4 vertebrae with separate injections at each vertebra junction. The chemicals used for neurolysis of the nerves cause destructive fibrosis and cause a disruption of the sympathetic ganglia.

One of the initial clinical studies into Amcinonide, conducted by Woodford & Barry, 1979, compared topical applications Amcinonide to Triamcinolone Acetonide. Specifically, 0.1% strength preparations of each compound were tested against 0.025% Synalar Gel and 0.1% Betnovate Cream using a vasoconstrictor assay to determine bioavailability and anti-inflammatory effects. All formulations had similar bioavailability profiles with the peak of the curve coming approximately 12 hours after topical administration and covering with an occlusive dressing. Concluding, the study found Amcinonide cream to be the most effective with the highest bio-activity and area under the curve (pharmacokinetics).

E. Fougera & Co., makers of the generic cream widely used in the United States as Lidocaine and Prilocaine Cream, 2.5%/2.5%, recommends different timing for application of the cream as well as length of anesthesia. They state the cream must be applied at least one hour before the start of a routine procedure and for two hours before the start of a painful procedure. Additionally, they state that the duration of effective skin anesthesia will be at least one hour after removal of the occlusive dressing.Lidocaine and Prilocaine Cream, 2.5%/2.5%, package insert.

A Zahn infarct is a pseudo-infarction of the liver, consisting of an area of congestion with parenchymal atrophy but no necrosis, and usually due to obstruction of a branch of the portal vein. Zahn infarcts are unique in that there is collateral congestion of liver sinusoids that do not include areas of anoxia seen in most infarcts. Fibrotic tissue may develop in the area of the infarct and it could be caused by an occlusive phlebitis in portal vein radicles. Non ischemic infarct of liver with lines of Zahn.

Subclavian steal syndrome (SSS), also called subclavian steal phenomenon or subclavian steal steno-occlusive disease, is a constellation of signs and symptoms that arise from retrograde (reversed) blood flow in the vertebral artery or the internal thoracic artery, due to a proximal stenosis (narrowing) and/or occlusion of the subclavian artery. The arm may be supplied by blood flowing in a retrograde direction down the vertebral artery at the expense of the vertebrobasilar circulation. This is called the subclavian steal. It is more severe than typical vertebrobasilar insufficiency.

Hypertension is also associated with impaired cognition in an aging population. Hypertension- related cognitive impairment and dementia may be a consequence of a single infarct due to occlusion of a "strategic" larger vessel or multiple lacunar infarcts due to occlusive small vessel disease resulting in subcortical white matter ischemia. Several clinical trials suggest that antihypertensive therapy has a beneficial effect on cognitive function, although this remains an active area of investigation. Cerebral blood flow remains unchanged over a wide range of arterial pressures (mean arterial pressure of 50–150 mmHg) through a process termed autoregulation of blood flow.

A thick layer of topical MAL or 5-ALA cream is applied to the lesion and a small area surrounding the lesion, which is then covered with an occlusive dressing and left for a period of time. During this time the photosensitizer accumulates in the target cells within the AK lesion. The dressings are then removed and the lesion is treated with light at a specified wavelength. Multiple treatment regimens using different photosensitizers, incubation times, light sources, and pretreatment regimens have been studied and suggest that longer incubation times lead to higher rates of lesion clearance.

Urokinase is effective for the restoration of flow to intravenous catheters blocked by clotted blood or fibrin (catheter clearance). Catheters are used extensively to administer treatments to patients for such purposes as dialysis, nutrition, antibiotic treatment and cancer treatment. Approximately 25% of catheters become blocked, meaning that affected patients cannot receive treatment until the catheter has been cleared or replaced. Urokinase is also used clinically as a thrombolytic agent in the treatment of severe or massive deep venous thrombosis, peripheral arterial occlusive disease, pulmonary embolism, acute myocardial infarction (AMI, heart attack), and occluded dialysis cannulas (catheter clearance).

Deaths result from several reasons—stillbirths, birth defects, cannibalism, hypothermia, neglect of cubs by mothers, and infectious diseases. Compared to other felids, cheetahs need specialised care because of their higher vulnerability to stress-induced diseases; this has been attributed to their low genetic variability and factors of captive life. Common diseases of cheetahs include feline herpesvirus, feline infectious peritonitis, gastroenteritis, glomerulosclerosis, leukoencephalopathy, myelopathy, nephrosclerosis and veno-occlusive disease. High density of cheetahs in a place, closeness to other large carnivores in enclosures, improper handling, exposure to public and frequent movement between zoos can be sources of stress for cheetahs.

It is before and before and , perhaps because labialization is constrained by the spread front vowels; it does not occur before the back (rounded) vowels and . It is doubted by some scholars that true closure can be made by a labiodental gesture because of gaps between the incisors, which for many speakers would allow air to flow during the occlusion. This is particularly pertinent considering that one of the Kukuya words with this consonant, , means a 'gap between filed incisors,' a practice of the local people. The might therefore be better characterized as a labiodental nasal approximant than as a nasal occlusive.

Khachigian invented Dz13, a molecule that targets the transcription factor c-Jun, implicated in a range of common proliferative, occlusive and inflammatory diseases. In 1999 Khachigian reported the first use of catalytic DNA as new experimental drugs in an animal model of any kind. In 2013 he reported the first clinical use of catalytic DNA in human subjects. This was later followed by numerous other independent, some multi-center, clinical trials evaluating DNAzymes in humans, including DNAzymes targeting EBV-LMP1 in patients with nasopharyngeal cancer and DNAzymes targeting another nuclear transcription factor GATA3 in patients with allergic asthma demonstrating DNAzyme efficacy and safety.

Other additional tests included arterial blood flow measurements by an occlusive cuff placed around the leg, facial photographs taken before flight and during flight to study the "puffy face syndrome", venous compliance, hemoglobin, urine specific gravity, and urine mass measurements. These inflight tests gave additional information about fluid distribution and fluid balance to get a better understanding of the fluid shift phenomena. The Skylab 3 biological experiments studied the effects of microgravity on mice, fruit flies, single cells and cell culture media. Human lung cells were flown to examine the biochemical characteristics of cell cultures in the microgravity environment.

Not only is this an aesthetically unappealing condition, but there is evidence to support that disciform erythrasma can be an early sign of type 2 diabetes mellitus. The generalized erythrasma is most commonly seen in type 2 diabetes mellitus where the lesions go beyond the areas of the body where skin is rubbing together. It is prevalent among diabetics and the obese, and in warm climates; it is worsened by wearing occlusive clothing. The presence of erythrasma is approximately 4% and is more likely to be found in the subtropical and tropical areas compared to the rest of the world.

The dressings used for the technique include foam dressings and gauze, sealed with an occlusive dressing intended to contain the vacuum at the wound site. Where NPWT devices allow delivery of fluids, such as saline or antibiotics to irrigate the wound, intermittent removal of used fluid supports the cleaning and drainage of the wound bed. In 1995, Kinetic Concepts was the first company to have a NPWT product cleared by the US Food and Drug Administration. Following increased use of the technique by hospitals in the US, the procedure was approved for reimbursement by the Centers for Medicare and Medicaid Services in 2001.

The sickling reaction is reversible after re-oxygenating the hemoglobin, therefore, red blood cells can go through cycles of sickling and unsickling depending on the concentration of oxygen present in the bloodstream. Red blood cells that are sickle-shaped lack flexibility and stick to the walls of blood vessels decreasing or stopping the flow of oxygen to nearby tissues. This decrease in oxygen to the tissues cause vaso-occlusive crisis which presents itself in muscle pain and injury to tissues. Some symptoms of sickle cell anemia include fever, fatigue from anemia, swelling of the hands and feet, stroke, and organ failure.

This leads to the so-called vaso-occlusive crisis, which is a hallmark of the disease. If fetal hemoglobin remains relatively high after birth, the number of painful episodes decreases in patients with sickle-cell disease and they have a better prognosis. Fetal hemoglobin's role in reducing disease severity comes from its ability to disrupt the formation of hemoglobin S chains within red blood cells. Interestingly, while higher levels of hemoglobin F were associated with improvement of some symptoms, including the frequency of painful episodes, leg ulcers and the general severity of the disease, it had no correlation to others.

More current information is contradictory about the dangers of the ingestion of groundsel. A heavily referenced paper from 1989 suggests that the response is immediate and gives pre-ambulatory care recommendations. A Canadian poisonous plants information database references a paper from 1990 in presenting this prenatal warning: "In a case of prenatal exposure, a mother ingested tea containing an estimated 0.343 milligram of senecionine, resulting in fatal veno-occlusive disease in a newborn infant." Information about the pyrrolizidine alkaloids, the substance present in Senecio vulgaris is much less contradictory and all warn of accumulation of the alkaloid.

Each place of articulation produces a different set of consonant sounds, which are further distinguished by manner of articulation, or the kind of friction, whether full closure, in which case the consonant is called occlusive or stop, or different degrees of aperture creating fricatives and approximants. Consonants can also be either voiced or unvoiced, depending on whether the vocal cords are set in vibration by airflow during the production of the sound. Voicing is what separates English in bus (unvoiced sibilant) from in buzz (voiced sibilant). Some speech sounds, both vowels and consonants, involve release of air flow through the nasal cavity, and these are called nasals or nasalized sounds.

On 23 February 2020, the American Society of Retina Specialists reported side effects of the drug, specifically in 14 cases of retinal vasculitis reported in Beovu patients, 11 of the cases were occlusive retinal vasculitis that can lead to vision loss. Novartis responded with a statement standing behind the efficacy of Beovu. On 11 June 2020, the FDA approved an updated Beovu label, that included additional safety information specifically including the characterization of adverse events, retinal vasculitis and retinal vascular occlusion, as part of the spectrum of intraocular inflammation observed in HAWK (NCT02307682) and HARRIER (NCT02434328) clinical trials and noted in the original prescribing information.

All the paleohispanic scripts, with the exception of the Greco-Iberian alphabet, share a common distinctive typological characteristic: they represent syllabic value for the occlusives, and monophonemic value for the rest of the consonants and vowels. In a writing system they are neither alphabets nor syllabaries, but are rather mixed scripts that are normally identified as semi-syllabaries. The basic signary contains 28 signs: 5 vowels, 15 syllabic and 8 consonantic (one lateral, two sibilants, two rhotic and three nasals). The northeastern script was very nearly deciphered in 1922 by Manuel Gómez-Moreno Martínez, who systematically linked the syllabic signs with the occlusive values.

In linguistics, pre-stopping, also known as pre-occlusion or pre-plosion, is a phonological process involving the historical or allophonic insertion of a very short stop consonant before a sonorant, such as a short before a nasal or a lateral . The resulting sounds () are called pre-stopped consonants, or sometimes pre-ploded or (in Celtic linguistics) pre-occluded consonants, although technically may be considered an occlusive/stop without the pre- occlusion. A pre-stopped consonant behaves phonologically as a single consonant. That is, like affricates and trilled affricates, the reasons for considering these sequences to be single consonants lies primarily in their behavior.

A significant proportion of artery flow-disrupting events occur at locations with less than 50% lumenal narrowing. Cardiac stress testing, traditionally the most commonly performed noninvasive testing method for blood flow limitations, generally only detects lumen narrowing of ~75% or greater, although some physicians advocate nuclear stress methods that can sometimes detect as little as 50%. The sudden nature of the complications of pre-existing atheroma, vulnerable plaque (non-occlusive or soft plaque), have led, since the 1950s, to the development of intensive care units and complex medical and surgical interventions. Angiography and later cardiac stress testing was begun to either visualize or indirectly detect stenosis.

If formaldehyde, chloroform, or DDT are used topically, care should be taken when dealing with the resulting morbidity. The T. penetrans flea can also be suffocated using occlusive petrolatum, while Vaseline will kill the organism as well, most likely due to suffocation as the stigmata would be covered. The gum of the mammee apple (Mammea americana), a fruit that also goes by the name Saint Domingo apricot, has also been used to kill the chigoe flea, though this has not been reported in the main T. penetrans literature. Even without treatment, the burrowed fleas will die within five weeks and are naturally sloughed off as the skin sheds.

While most products are manufactured at 0.1% strength ointment, cream, or lotion, it is important to note that none of the producers sell Amcinonide as an over-the-counter (OTC) medication but only as a prescription product. While the initial patents obtained by American Cyanamid company in the late 1970s/ early 1980s for ointment, cream, and lotion formulations have expired, new patents have been obtained for alternative transdermal delivery methods.Google.com: Topical Ointment PatentGoogle.com: Topical Ointment Patent 2 More recently, however, the drug formulation itself has not been patented but ways to incorporate it into occlusive dressings such as a pressure sensitive adhesive layer as demonstrated by Senju USA, Inc.

All topical products, including lotions, can result in the percutaneous (through the skin) absorption of their ingredients. Though this has some use as a route of drug administration, it more commonly results in unintended side effects. For example, medicated lotions such as diprolene are often used with the intention of exerting only local effects, but absorption of the drug through the skin can occur to a small degree, resulting in systemic side effects such as hyperglycemia and glycosuria. Absorption through the skin is increased when lotions are applied and then covered with an occlusive layer, when they are applied to large areas of the body, or when they are applied to damaged or broken skin.

Porcaro died at Humana Hospital-West Hills on the evening of August 5, 1992, at the age of 38, earlier falling ill after spraying insecticide in the yard of his Hidden Hills home. The coroner ruled out an accident, and determined a heart attack due to occlusive coronary artery disease caused by atherosclerosis resulting from cocaine use. His funeral was held on August 10 in the Forest Lawn – Hollywood Hills Cemetery, where he was buried on the Lincoln Terrace, lot 120. The Jeff Porcaro Memorial Fund was established to benefit the music and art departments of Grant High School in Los Angeles, California, where he was a student in the early 1970s.

The decipherment was based on the existence of a large number of coin legends (some of them bearing Latin inscriptions) that could easily be linked to ancient place names known from Roman and Greek sources. There are two variants of the northeastern Iberian script: the dual variant is almost exclusive to the ancient inscriptions from the 4th and 3rd centuries BCE and its distinctive characteristic is the use of the dual system. This system was discovered by Joan Maluquer de Motes in 1968 and allows differentiation of the occlusive signs (dentals and velars) between voiced and unvoiced by the use of an additional stroke. The simple sign represents the voiced value whilst the complex sign represents the unvoiced value.

Management is similar to vaso- occlusive crisis, with the addition of antibiotics (usually a quinolone or macrolide, since cell wall-deficient ["atypical"] bacteria are thought to contribute to the syndrome), oxygen supplementation for hypoxia, and close observation. In the absence of high quality evidence regarding the effectiveness of antibiotics for acute chest syndrome in people with sickle cell disease, there is no standard antibiotic treatment as of 2019. It is recommended that people with suspected acute chest syndrome should be admitted to the hospital with worsening A-a gradient an indication for ICU admission. Should the pulmonary infiltrate worsen or the oxygen requirements increase, simple blood transfusion or exchange transfusion is indicated.

There is also a higher prevalence of sickle cell trait in areas that malaria is commonly found, with the prevalence in some parts of Africa and Saudi Arabia being as high as 25% and 60%, respectively. Individuals who have HbAS have about 40%HbS, 56% HBA, and are usually asymptomatic unless there is a severe lack of oxygen to the body (hypoxia) which can lead to symptoms of sickle cell disease. However, HbAS does not cause vaso-occlusive crisis, which is known to be associated with sickle cell disease. Patients that are homozygous for HbS have multi-stranded fibers that induce a change in shape of red blood cells from biconcave disks to elongated crescents.

Tobacco and smoking began to be engraved in the culture and lifestyle of the American public, associated with things such as "sexy, cool, masculine".Brandt, Allan M. "The Cigarette Century: the Rise, Fall, and Deadly Persistence of the Product That Defined America." New York: Basic, 2009, The popularity of tobacco was soon replaced with skepticism and many wanting to know the health risks of smoking. Research and analysis followed in order to understand these risks, with shocking conclusions and connections to diseases( coronary disease, coronary heart disease, peripheral arterial occlusive disease, cerebrovascular disease, lung cancer, cancer of the larynx, oral cancer, cancer of the esophagus, cancer of the bladder, cancer of the pancreas) that left many in shock.

Sometimes, Mecklenburg is pronounced . This is because the digraph marks a preceding short vowel in High German. Mecklenburg however is within the historical Low German language area, and the "c" appeared in its name during the period of transition to Standard, High German usage (Low German authors wrote the name Meklenborg or Męklenborg, depicting proper Low German pronunciation, which itself was a syncope of Middle Low German Mekelenborg). The introduction of the "c" is explained as follows: Either the "c" signals the stretched pronunciation of the preceding "e" (Dehnungs-c), or it signals the pronunciation of the subsequent "k" as an occlusive [k] to prevent it from falsely being rendered as a fricative [χ] following a Low German trend.

Russert's longtime friend and physician, Dr. Michael Newman, said that his asymptomatic coronary artery disease had been controlled with medication (LDL-C was <70 mg/dL) and exercise, and that he had performed well on a stress test on April 29 of that year. An autopsy performed on the day of his death determined that his history of coronary artery disease led to a myocardial infarction (heart attack) and ventricular fibrillation with the immediate cause being an occlusive coronary thrombosis in the left anterior descending artery resulting from a ruptured cholesterol plaque. Russert is buried at Rock Creek Cemetery. The Newseum in Washington, D.C., exhibited a re-creation of Russert's office with original elements such as his desks, bookshelves, folders, loose leaf papers and notebooks.

A phonemic labiodental nasal, , has only been reported from this one language. It is "accompanied by strong protrusion of both lips", being before and before and , perhaps because labialization is constrained by the spread front vowels; it does not occur before back (rounded) vowels. However, there is some doubt that a true stop can be made by this gesture due to gaps between the incisors, which are filed to points by the Teke people and would allow air to flow during the occlusion; this is particularly pertinent considering that one of the words with this consonant, , means a 'gap between filed incisors'. Because of these factors, Teke might be better characterized as a labiodental nasal approximant ( in IPA), rather than a nasal occlusive.

The Italian School of Salerno in the twelfth century recommended bandages hardened with a flour and egg mixture as did Medieval European bonesetters, who used casts made of egg white, flour, and animal fat. By the sixteenth century the famous French surgeon Ambroise Paré (1517–1590), who championed more humane treatments in medicine and promoted the use of artificial limbs, made casts of wax, cardboard, cloth, and parchment that hardened as they dried. These methods all had merit, but the standard method for the healing of fractures was bed rest and restriction of activity. The search for a simpler, less-time consuming, method led to the development of the first modern occlusive dressings, stiffened at first with starch and later with plaster-of-paris.

Many practitioners use The Occlusion Cuff as well as BFR protocols based on published scientific literature. The current approaches that focus on applying BFR during exercise consist of automatic pneumatic tourniquet systems, handheld inflatable device or automatic inflatable devices, called The Occlusion Cuff. Research demonstrating the influence of thigh circumference and cuff width on occlusion pressure has accentuated a likely need for an individualised approach to BFR, particularly with regard to the setting of the restriction pressure. More recently, a technique to calculate and prescribe the occlusive stimulus as a percentage of total limb occlusion pressure is just one example of efforts to account for the above factors and provide an individualised approach to prescribing BFR training that is relatively quick and inexpensive.

Historically, arterial wall fixation, staining and thin section has been the gold standard for detection and description of atheroma, after death and autopsy. With special stains and examination, micro calcifications can be detected, typically within smooth muscle cells of the arterial media near the fatty streaks within a year or two of fatty streaks forming. Interventional and non-interventional methods to detect atherosclerosis, specifically vulnerable plaque (non-occlusive or soft plaque), are widely used in research and clinical practice today. Carotid Intima-media thickness Scan (CIMT can be measured by B-mode ultrasonography) measurement has been recommended by the American Heart Association as the most useful method to identify atherosclerosis and may now very well be the gold standard for detection.

Repeated application (typically over a few days) of emollients or skin lotions/creams to the affected area will likely result in quick alleviation of xeroderma. In particular, application of highly occlusive barriers to moisture, such as petrolatum, vegetable oils/butters, and mineral oil have been shown to provide excellent results. Many individuals find specific commercial skin creams and lotions (often comprising oils, butters, and or waxes emulsified in water) quite effective (although individual preferences and results vary among the wide array of commercially available creams). Lanolin, a natural mixture of lipids derived from sheep's wool, helps replace natural lipids in human skin and has been used since ancient times (and in modern medicine) as among the most powerful treatments for xeroderma.

Yerba for sale in the open-air market of La Boqueria in Barcelona, Spain Paraguayans have a tradition of mixing mate with crushed leaves, stems, and flowers of the plant known as (the flower of August, plants of the genus Senecio, particularly Senecio grisebachii), which contain pyrrolizidine alkaloids. Modifying mate in this fashion is potentially toxic, as these alkaloids can cause veno-occlusive disease, a rare condition of the liver which results in liver failure due to progressive occlusion of the small venous channels. Mate has also become popular outside of South America. In the tiny hamlet of Groot Marico, North West Province, South Africa, mate was introduced to the local tourism office by the returning descendants of the Boers, who in 1902 had emigrated to Patagonia in Argentina after losing the Anglo Boer War.

The phoneme /Ɂ/ presents a widely observed frequency within the Totonac languages spoken in the areas of Papantla and Xicotepec de juarez (Ashmann, 1973 y Reid & Bishop, l974). Crescencio García Ramos, in his work about the phonology of the Totonac of El Tajin, notes the mechanical character of the glottal closure and at the same time he points at the “operative importance” in certain positions (García Ramos, l979: 153). He also presents a series of occlusive glottalized consonants listed here: /pɁ/, /tɁ/, /kɁ/, /qɁ/, /cɁ/, /čɁ/, /λɁ/. In the variant that is studied here, there is an observed tendency to the disappearance of the glottal as realization of the phoneme /Ɂ/; this phenomenon is also mentioned by McQuown in the Coatepec variant: “the phoneme /Ɂ/ disappear under various circumstances” (McQuown, 1990: 85-86).

Efficacy of vasopressin on systemic hemodynamics in catecholamine-resistant septic and postcardiotomy shock have been studied and published first in 2001 Later, the group concluded the ischemic skin lesions (ISL) developed in patients with catecholamine-resistant vasodilatory shock have multi-factorial cause and shall not necessarily been seen a side effect of AVP solely. The presence of septic shock and a history of peripheral arterial occlusive disease are independent risk factors for the development of ISL. In the last decade, in early hyperdynamic septic shock, the administration of high-dose AVP as a single agent proved to fail to increase mean arterial pressure in the first hour but maintains it above 70mmHg in two-thirds of patients at 48h. AVP decreases NE exposure, has no effect on the PrCO(2) - PaCO(2 )difference, and improves renal function and SOFA score.

Portal vein thrombosis on computed tomography (left) and cavernous transformation of the portal vein after 1 year (right) The diagnosis of portal vein thrombosis is usually made with imaging confirming a clot in the portal vein; ultrasound is the least invasive method and the addition of Doppler technique shows a filling defect in blood flow. PVT may be classified as either occlusive or nonocclusive based on evidence of blood flow around the clot. An alternative characterization based on site can be made: Type 1 is limited to the main portal vein, Type 2 involves only a portal vein branch (2a, or 2b if both branches are affected), and Type 3 if clot is found throughout both areas. Determination of condition severity may be derived via computed tomography (CT) with contrast, magnetic resonance imaging (MRI), or MR angiography (MRA).

There is ongoing discussion as to how the distinction between what were historically described as 'velar' and 'uvular' clicks is best described. The 'uvular' clicks are only found in some languages, and have an extended pronunciation that suggests that they are more complex than the simple ('velar') clicks, which are found in all. Nakagawa (1996) describes the extended clicks in Gǀwi as consonant clusters, sequences equivalent to English st or pl, whereas Miller (2011) analyses similar sounds in several languages as click–non-click contours, where a click transitions into a pulmonic or ejective articulation within a single segment, analogous to how English ch and j transition from occlusive to fricative but still behave as unitary sounds. With ejective clicks, for example, Miller finds that although the ejective release follows the click release, it is the rear closure of the click that is ejective, not an independently articulated consonant.

Although Neapolitan shares a high degree of its vocabulary with Italian, the official language of Italy, differences in pronunciation often make the connection unrecognizable to those without knowledge of Neapolitan. The most striking phonological difference is the Neapolitan weakening of unstressed vowels into schwa (schwa is pronounced like the a in about or the u in upon). However it is also possible (and quite common for some Neapolitans) to speak standard Italian with a "Neapolitan accent"; that is, by pronouncing un-stressed vowels as schwa or by pronouncing the letter s as (like the sh in ship) instead of (like the s in sea or the ss in pass) when the letter is in initial position followed by a consonant, but not when it is followed by a dental occlusive or (at least in the purest form of the language) but by otherwise using only entirely standard words and grammatical forms. This is not Neapolitan proper, but a mere difference in Italian pronunciation.

Although sebaceous gland activity in the skin increases during the late stages of pregnancy, pregnancy has not been reliably associated with worsened acne severity. In general, topically applied medications are considered the first-line approach to acne treatment during pregnancy, as they have little systemic absorption and are therefore unlikely to harm a developing fetus. Highly recommended therapies include topically applied benzoyl peroxide (pregnancy category C) and azelaic acid (category B). Salicylic acid carries a category C safety rating due to higher systemic absorption (9–25%), and an association between the use of anti-inflammatory medications in the third trimester and adverse effects to the developing fetus including too little amniotic fluid in the uterus and early closure of the babies' ductus arteriosus blood vessel. Prolonged use of salicylic acid over significant areas of the skin or under occlusive (sealed) dressings is not recommended as these methods increase systemic absorption and the potential for fetal harm.

The US label for the use of inotuzumab ozagamicin carries an FDA black box warning concerning the risk of liver toxicity, in particular hepatic veno-occlusive disease (VOD), which has been fatal in some people. The risk of this is higher in people who take the drug before having hematopoietic stem cell transplantation (HSCT) and more people die who have HSCT following treatment with this drug, than people who have HSCT taking other chemotherapies. The risk gets higher as more rounds of treatment with inotuzumab ozogamicin are administered. The most common serious adverse reactions in people taking the drug in the clinical trial leading to approval were infections (23%), loss of neutrophils with fever (11%), hemorrhage (5%), stomach pain (3%), fever (3%), VOD (2%), and tiredness (2%). More than 20% of people had the following adverse reactions: loss of platelets (51%), loss of neutrophils (49%), infections (48%), anemia (36%), leukopenia (35%), tiredness (35%), hemorrhage (33%), fever (32%), nausea (31%), headache (28%), loss of neutrophils with fever (26%), elevated transaminases (26%), stomach pain (23%), and jaundice (21%).
