Molluscum contagiosum are small, benign bumps on the skin caused by a pox virus.
|
|
Molluscum contagiosum consists of small, flesh-colored bumps called mollusca, caused by a pox virus.

Here again are the manifestations of terror: the purple cancerous lesions of Kaposi's sarcoma, fatal when they migrated to your lungs; toxoplasmosis — a brain disease that turned 42.63-somethings into end-stage Alzheimer's patients; pneumocystis carinii, which flooded your lungs until you drowned; cytomegalovirus, which led to blindness, so that young men in AIDS wards were "hugging walls and scraping the air to find their nurses"; molluscum contagiosum, covering the body in "small, barnacle-like papules" that oozed pus; peripheral neuropathy, with which a mere brush of a sheet against your skin felt like an electric shock; and cryptosporidiosis, a parasite that took over people's gastrointestinal tract, slowly starving them to death.

Molluscum contagiosum virus (MCV) is a DNA poxvirus that causes the human skin infection molluscum contagiosum. Molluscum contagiosum affects about 200,000 people a year, about 1% of all diagnosed skin diseases. Diagnosis is based on the size and shape of the skin lesions and can be confirmed with a biopsy, as the virus cannot be routinely cultured. Molluscum contagiosum virus is the only species in the genus Molluscipoxvirus.

Using qPCR analysis, it was determined that there was significant Molluscum contagiosum virus in the plasma of one patient who had a large t-cell deficiency. The patient was given CMX-001 antiviral agent as a treatment because of her severe molluscum contagiosum symptoms. Before administering the CMX-001 drug, Molluscum contagiosum virus DNA was found in 50% of her plasma samples, whereas DNA was found in 20% of samples after administering the drug. This is the first time molluscum contagiosum DNA was ever detected in the blood of a patient.

|
As of 2010, approximately 122 million people were affected worldwide by molluscum contagiosum (1.8% of the population).

Bacterial infections, or pathogens, make up the largest category of include Furuncles, Carbuncles, Folliculitis, Impetigo, Cellulitis or Erysipelas, and Staphylococcal disease. These range in severity, but most are quickly identified by irritated and blotchy patches of skin. Bacterial infections, of all skin infections, are typically the easiest to treat, using a prescribed anti-bacterial lotion or crème. Molluscum Contagiosum is caused a DNA pox virus called the molluscum contagiosum virus.

Patients are generally susceptible to recurrent sinopulmonary and ear infections in childhood, and may be more susceptible to certain viruses including Epstein-Barr virus, BK virus, and molluscum contagiosum.
|
|
As the name implies, molluscum contagiosum is extremely contagious. Transmission of the molluscum contagiosum virus can occur many different ways including direct skin contact (e.g., contact sports or sexual activity), contact with an infected surface (fomite), or autoinoculation (self-infection) by scratching or picking molluscum lesions and then touching other parts of the skin not previously affected by the virus. Children are particularly susceptible to autoinoculation and may have widespread clusters of lesions.

One randomized double-blind Phase III clinical study found clearance of genital warts (an FDA-approved indication) improved from 9% with placebo to 24.9% with 3.75% imiquimod cream applied for up to eight weeks. Imiquimod has been tested for treatment of molluscum contagiosum. Two large randomized controlled trials, however, found no evidence of effectiveness of imiquimod in treating children with molluscum contagiosum, and concerning adverse effects were also noted. These disprove earlier anecdotal claims and smaller, less reliable studies.

Most cases of molluscum contagiosum will clear up naturally within two years (usually within nine months). So long as the skin growths are present, there is a possibility of transmitting the infection to another person. When the growths are gone, the possibility of spreading the infection is ended. Unlike herpesviruses, which can remain inactive in the body for months or years before reappearing, molluscum contagiosum does not remain in the body when the growths are gone from the skin and will not reappear on their own.

Four genera of poxviruses may infect humans: orthopoxvirus, parapoxvirus, yatapoxvirus, molluscipoxvirus. Orthopox: smallpox virus (variola), vaccinia virus, cowpox virus, monkeypox virus; Parapox: orf virus, pseudocowpox, bovine papular stomatitis virus; Yatapox: tanapox virus, yaba monkey tumor virus; Molluscipox: molluscum contagiosum virus (MCV). The most common are vaccinia (seen on Indian subcontinent) and molluscum contagiosum, but monkeypox infections are rising (seen in west and central African rainforest countries). The similarly named disease chickenpox is not a true poxvirus and is actually caused by the herpesvirus varicella zoster.

Once an infection occurs, the virus will spread to nerve cells, where it remains for the rest of the person's life. Occasionally, the virus will suddenly display recurring symptoms, or flares.Berman, Kevin. "Molluscum Contagiosum" MedlinePlus Medical Encyclopedia.

People with severely weakened immune systems and molluscum contagiosum may have bumps or lesions that are greater than 15 millimeters and look different than normal. Most typical therapies are ineffective in treating these people. The recommended treatment in this case are therapies that help boost the immune system.

Bateman is credited for providing names and descriptions for a number of dermatological diseases, including lichen urticatus, alopecia areata, erythema multiforme and molluscum contagiosum. The work of Willan and Bateman influenced many physicians, such as Thomas Addison (1793–1860), who was a pupil of Bateman, and Laurent- Théodore Biett (1781–1840), who introduced their methodology into French medicine.

They usually go away within a year without scarring. The infection is caused by a poxvirus called the molluscum contagiosum virus (MCV). The virus is spread either by direct contact, including sexual activity, or via contaminated objects such as towels. The condition can also be spread to other areas of the body by the person themselves.
|
|
For mild cases, over-the-counter wart medicines, such as salicylic acid may shorten infection duration. Daily topical application of tretinoin cream may also trigger resolution. Studies have found cantharidin to be an effective and safe treatment for removing molluscum contagiosum. This medication is usually well tolerated though mild side effects such as pain or blistering are common.

Podophyllotoxin (PPT), also known as podofilox, is a medical cream that is used to treat genital warts and molluscum contagiosum. It is not recommended in HPV infections without external warts. It can be applied either by a healthcare provider or the person themselves. It is a non-alkaloid toxin lignan extracted from the roots and rhizomes of Podophyllum species.

Several other conditions may mimic lymphangioma circumscriptum. These conditions include infections such as an outbreak of herpes simplex, herpes simplex vegetans, molluscum contagiosum, verruca vulgaris, and condyloma acuminatum. Similarly, benign and cancerous non-infectious conditions may also present in a similar manner and include conditions such as angiokeratoma, dermatitis herpetiformis, hemangioma, epidermal nevus, lymphangiectasia, melanoma, angiosarcoma, and metastatic carcinomas.

Approximately 122 million people globally were affected by molluscum contagiosum as of 2010 (1.8% of the population). It is more common in children between the ages of one and ten years old. The condition has become more common in the United States since 1966. But having an infection is not a reason to keep a child out of school or daycare.

Figure 1. Round, hard, flesh colored bumps that are the symptom of Molluscum contagiosum virus infection. This is a viral infection of the skin that usually presents in children ages 1–10 and immunocompromised patients. The main symptom of this disease is round, hard, flesh colored, painless bumps, with sunken centers that are apparent on the surface of the skin (Figure 1).

The most common fomites for molluscum contagiosum transmission are clothing, towels, bathing sponges, toys, and sports equipment. Additionally, the virus can spread to other skin areas of one's body through itching or rubbing the virus. It can also be spread in adults through sexual contact. The virus is not circulated throughout the body, and thus, cannot be spread by coughing or sneezing.

CEDS has features similar to ALPS, another genetic disease of apoptosis, with the addition of an immunodeficient phenotype. Thus, the clinical manifestations include splenomegaly and lymphadenopathy, in addition to recurrent sinopulmonary infections, recurrent mucocutaneous herpesvirus, persistent warts and molluscum contagiosum infections, and hypogammaglobulinemia. There is sometimes lymphocytic infiltrative disease in parenchymal organs, but autoimmunity is minimal and lymphoma has not been observed in the CEDS patients.

The genome consists of a linear double stranded DNA molecule that is approximately 190 kilobases in length. The genome is unique in that the two ends of the double stranded DNA sequence are inverted repeats of each other. This inverted terminal sequence is 4.7 kilobases in length, but can vary from 0.7-12 kilobases among poxviruses. There are 182 genes that are encoded by Molluscum contagiosum virus.

There have been links made between HPV and vulvar cancer, though HPV most often causes cervical cancer. Genital herpes is mostly asymptomatic but can present with small blisters that break open into ulcers. HIV/AIDS is mostly transmitted through sexual activity, and the vulva in some cases can be affected by sores. A highly contagious viral infection is molluscum contagiosum which is transmissible on close contact and causes water warts.

Molluscum contagiosum (MC), sometimes called water warts, is a viral infection of the skin that results in small raised pink lesions with a dimple in the center. They may become itchy or sore, and occur singularly or in groups. Any area of the skin may be affected, with abdomen, legs, arms, neck, genital area, and face being the most common. Onset of the lesions is around seven weeks after infection.

After a short stint in Jaunpur at the Sitapur Eye Hospital, he joined the Gandhi Eye Hospital in Aligarh as an assistant professor in charge of the research wing from 1956 to 1960. He carried out extensive research on trachoma. His work on Molluscum Contagiosum was acknowledged in the famous Ophthalmology Book series of Sir Stewart Duke Elder. He helped set up the eye department at P.G.I. Chandigarh in 1960.

A very rare genetic disorder of the immune system can also be caused by mutations in this gene. This disease, called CEDS, stands for “Caspase eight deficiency state.” CEDS has features similar to ALPS, another genetic disease of apoptosis, with the addition of an immunodeficient phenotype. Thus, the clinical manifestations include splenomegaly and lymphadenopathy, in addition to recurrent sinopulmonary infections, recurrent mucocutaneous herpesvirus, persistent warts and molluscum contagiosum infections, and hypogammaglobulinemia.

These lesions are generally not painful, but they may itch or become irritated. Picking or scratching the bumps may lead to a spread of the viral infection responsible for molluscum contagiosum, an additional bacterial infection, and scarring. In about 10% of the cases, eczema develops around the lesions. Individual molluscum lesions may go away on their own within two months and generally clear completely without treatment or scarring in six to twelve months.

For adults, molluscum infections are often sexually transmitted, but in wrestling, it is spread either through direct contact or through contact with shared items such as gear or towels. Molluscum Contagiosum can be identified by pink bulbous growths that contain the virus. These typically grow to be 1–5 millimeters in diameter, and last from 6 to 12 months without treatment and without leaving scars. Some growths may remain for up to 4 years.

Molluscum contagiosum virus only infects human epidermal cells. It is not spread throughout the body, which explains why the virus cannot be transmitted through coughing or sneezing. People have attempted to grow the virus in cell culture to study its molecular properties, but have been largely unsuccessful due to it only infecting epidermal cells. However, there is evidence that it has the ability to adapt and survive in different types of cells in humans with severely compromised immune systems.

Lemon myrtle essential oil possesses antimicrobial properties; however the undiluted essential oil is toxic to human cells in vitro. When diluted to approximately 1%, absorption through the skin and subsequent damage is thought to be minimal. Lemon myrtle oil has a high Rideal–Walker coefficient, a measure of antimicrobial potency. Use of lemon myrtle oil as a treatment for skin lesions caused by molluscum contagiosum virus (MCV), a disease affecting children and immuno-compromised patients, has been investigated.

Schoenfisch is a cofounder of Novan, Inc. (2006). The public pharmaceutical company focuses primarily on the development of nitric oxide release-based therapies for dermatological indications. One lead product is an anti-acne drug, which has completed Phase 3 clinical trial. At least three other drugs are being developed, including topical anti-virals for the treatment of molluscum contagiosum (Phase 3) and external genital warts caused by the human papillomavirus (Phase 2), and a topical for the treatment of onychomycosis (Phase 2).

Molluscum lesions on an arm Molluscum contagiosum lesions are flesh-coloured, dome-shaped, and pearly in appearance. They are often 1–5 mm in diameter, with a dimpled center. Molluscum lesions are most commonly found on the face, arms, legs, torso, and armpits in children. Adults typically have molluscum lesions in the genital region and this is considered to be a sexually transmitted infection; because of this, if genital lesions are found on a child, sexual abuse should be suspected.

The Molluscum contagiosum virus virion is described as oval-shaped and has the dimension of approximately 320 nm × 250 nm × 200 nm. The virus has two distinct infectious particles called the mature virion (MV) and the enveloped virion (EV), which differ in that the EV contains a second outer cellular membrane. Poxviridae is the only virus family that contains both enveloped and non-enveloped infectious particles. Other structures of the EV and MV virion include the nucleocapsid, core wall, and two lateral bodies.

Molluscum contagiosum virus, like other poxviruses, replicates entirely in the cytoplasm of the host cell. This is a property unique to poxviruses, as all other DNA viruses replicate in the nucleus. Therefore, because the host cell proteins for DNA replication are present inside the nucleus, this virus has to bring or encode for all of the proteins needed for replication. Each virion sets up a region in the cytoplasm, called a 'viral factory' where DNA replication, transcription, and translation all occur sequentially.

Due to the variable clinical and histological appearance of SGc, this condition is often misdiagnosed. The average delay in diagnosis has been reported to be 1 – 2.9 years from expected onset of the lesion. Patients with ocular sebaceous carcinomas present with nonhealing eyelid tumors that are often misdiagnosed for more common benign conditions such as chalazion or blepharoconjunctivitis. Extraocular SGc appears similarly to skin cancers such as basal cell carcinoma, squamous cell carcinoma and benign lesions such a molluscum contagiosum and pyogenic granuloma.

Water warts of molluscum contagiosum Pubic hair with crab lice Vulvar organs and tissues can become affected by different infectious agents such as bacteria and viruses, or infested by parasites such as lice and mites. Over thirty types of pathogen can be sexually transmitted, and many of these affect the genitals. Most STIs do not produce symptoms or symptoms may be mild and not be indicative of an STI. The practice of safe sex can greatly reduce the risk of infection from many sexually transmitted pathogens.

Ayurvedic skincare is derived from medicinal practices that began over 5,000-years ago in India. Ayurvedic medicine and healing practices are based on Indian philosophical, psychological, conventional, and medicinal understandings. Most of the ayurvedic skincare products contain the following herbs—aloe vera, almond, avocado, carrot, castor, clay, cocoa, coconut oil, cornmeal, cucumber, cutch tree, emu oil, ginkgo biloba, ginseng, grape seed oil, ground almond and walnut shell, horse chestnut, witch hazel, and honey. Ayurvedic approaches have been used in molluscum contagiosum, lymphatic filariasis, vitiligo and lichen planus.

A 2014 systematic review of case reports and case series concluded that the limited available data suggest pulsed dye laser therapy is a safe and effective treatment for molluscum contagiosum and is generally well tolerated by children. Side effects seen with pulsed dye laser therapy included mild temporary pain at the site of therapy, bruising (lasting up to 2–3 weeks), and temporary discoloration of the treated skin (as long as 1–6 months). No cases of permanent scarring have been reported. As of 2009, however, there is no evidence for genital lesions.

Molluscum contagiosum virus, similar to all poxviruses, produces two infectious particles mature virions (MV) and extracellular virions (EV), with the EV differing from the MV in that they possess an extra cellular membrane. To enter the cell, the membrane of MV fuses to the plasma membrane, specifically glycosaminoglycans, of the host cell and then enters via macropinocytosis. This process is initiated by the presence of phosphatidylserine molecules exposed on the MV cellular membrane. Similarly, the outer membrane of EV fuses to the plasma membrane, specifically glycosaminoglycans, of the host cell and also enters via macropinocytosis.

Philipp Josef Pick at Who Named It He was the first to describe the bacterial infection Trichomycosis palmellina, and independent of Heinrich Köbner (and shortly afterwards), he discovered Trichophyton tonsurans in eczema marginatum. He also made contributions in his research of molluscum contagiosum, melanosis lenticularis progressiva, urticaria pigmentosa, erythromelia and acne frontalis. With German dermatologist Karl Herxheimer, the eponymous "Pick-Herxheimer disease" is named, a disorder also known as acrodermatitis chronica atrophicans.Acrodermatitis chronica atrophicans Unbound Medicine He is credited for introducing iodoform into dermatology and for employing emplastrum saponatum salicylicum for the treatment of eczema.

Nearly all patients have recurrent or chronic upper and lower respiratory tract infections, with many requiring sinus surgery and myringotomy tube placement. Recurrent lung infections may lead to bronchiectasis or damage to the airways leaving them widened and scarred. The cutaneous or skin infections are distinctive and include severe and difficult to treat viral infections, such as herpes simplex virus, human papilloma virus, and molluscum contagiosum; bacteria such as Staphylococcus aureus; as well as fungal infections of the mouth or skin with Candida. Eczema is common, and can be quite severe and further complicated by bacterial infection.

Properly dosed and applied, the same properties have also been used therapeutically, for instance for treatment of skin conditions such as molluscum contagiosum infection of the skin. Cantharidin is classified as an extremely hazardous substance in the United States and is subject to strict reporting requirements by facilities that produce, store, or use it in significant quantities.As defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002). See "40 C.F.R.: Appendix A to Part 355—The List of Extremely Hazardous Substances and Their Threshold Planning Quantities" (PDF) (July 1, 2008 ed.).

Because molluscum contagiosum usually resolves without treatment and treatment options can cause discomfort to children, initial recommendations are often to simply wait for the lesions to resolve on their own. Of the treatments available, a meta-analysis of randomized controlled trials suggested that there is no difference between treatments in short term improvement, and no single treatment is significantly better than natural resolution of the condition. Bumps located in the genital area may be treated in an effort to prevent them from spreading. When treatment has resulted in elimination of all bumps, the infection has been effectively cured and will not reappear unless the person is reinfected.

In 1908, three Philadelphia researchers infected dozens of children with tuberculin at the St. Vincent's House orphanage in Philadelphia, causing permanent blindness in some of the children and painful lesions and inflammation of the eyes in many of the others. In the study, they refer to the children as "material used". In 1909, F. C. Knowles released a study describing how he had deliberately infected two children in an orphanage with Molluscum contagiosum—a virus that causes wart-like growths—after an outbreak in the orphanage, in order to study the disease. In 1911, Dr. Hideyo Noguchi of the Rockefeller Institute for Medical Research injected 146 hospital patients (some of whom were children) with a syphilis extract.

The signs and symptoms of DOCK8 deficiency are similar to the autosomal dominant form, STAT3 deficiency. However, in DOCK8 deficiency, there is no skeletal or connective tissue involvement, and affected individuals do not have the characteristic facial features of those with autosomal dominant hyper-IgE syndrome. DOCK8 deficient children often have eczema, respiratory and skin staphylococcus infections. Beyond these, many other recurrent infections have been observed, including recurrent fungal infections and recurrent viral infections (including molluscum contagiosum, herpes simplex, and herpes zoster), recurrent upper respiratory infection (including Streptococcus pneumoniae, Haemophilus influenzae, respiratory syncytial virus, and adenovirus), recurrent sinusitis, recurrent otitis media, mastoiditis, pneumonia, bronchitis with bronchiectasis, osteomyelitis, candidiasis, meningitis (caused by cryptococcus or H. influenzae), pericarditis, salmonella enteritis, and giardiasis.

Autoinoculation may also be used for the transplantation of a patient's own healthy bone marrow after recovering from a condition afflicting the tissue. Autoinoculation can also refer to the process by which viruses reproduce themselves within an organism by implanting themselves in an organism's cells, altering the metabolism, DNA repair, and replication processes of those cells, using those processes to reproduce and transmit itself throughout the organism. For example, warts and Molluscum contagiosum can be spread by this method if wart tissue cells (skin cells altered by a papillomavirus) are mechanically transported to another part of the body.American Family Physician This transmission or autoinoculation of the wart can occur by mechanical touching of one part of the organism to another, friction that removes a portion of the infected cells to an external surface (or another organism) and then reintroduces those cells upon contact with the body elsewhere, or when wart cells or tissue are transported though the blood stream of an organism.
