Ctenidium molluscum is a species of moss belonging to the family Hypnaceae. [1]
It is native to Eurasia and Northern America. [1]
Cantharidin is an odorless, colorless fatty substance of the terpenoid class, which is secreted by many species of blister beetles. Its main current use in pharmacology is treating molluscum contagiosum and warts topically. It is a burn agent and poisonous in large doses, and has been historically used as aphrodisiacs. In its natural form, cantharidin is secreted by the male blister beetle, and given to the female as a copulatory gift during mating. Afterwards, the female beetle covers her eggs with it as a defense against predators.
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. They usually go away within a year without scarring.
Cryosurgery is the use of extreme cold in surgery to destroy abnormal or diseased tissue; thus, it is the surgical application of cryoablation. Cryosurgery has been historically used to treat a number of diseases and disorders, especially a variety of benign and malignant skin conditions.
The current staging system for HIV infection in children was developed in 2005 and builds upon the staging system in place since 1987. A child is defined as someone under the age of 15. This staging system also requires the presence of HIV infection: HIV antibody for children aged 18 months or more; virological or p24 antigen positive test if aged under 18 months.
Imiquimod, sold under the brand name Aldara among others, is a medication that acts as an immune response modifier that is used to treat genital warts, superficial basal cell carcinoma, and actinic keratosis.
Molluscum contagiosum virus (MCV) is a species of 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. MCV is a member of the subfamily Chordopoxvirinae of family Poxviridae. Other commonly known viruses that reside in the subfamily Chordopoxvirinae are variola virus and monkeypox virus.
Ham Hill is a hill and area of chalk downland in Wiltshire, England, on the steep banks running alongside the road from the village of Ham to Buttermere, close to the Berkshire border. A biological Site of Special Scientific Interest, notified in 1971, covers 1.5 hectares of the site; this designation is due to the site's species-rich plant and insect communities, which include some rare species. Notable among these is the musk orchid, which has been confirmed at only one other site in Wiltshire.
The Koebner phenomenon or Köbner phenomenon, also called the Koebner response or the isomorphic response, attributed to Heinrich Köbner, is the appearance of skin lesions on lines of trauma. The Koebner phenomenon may result from either a linear exposure or irritation. Conditions demonstrating linear lesions after a linear exposure to a causative agent include: molluscum contagiosum, warts and toxicodendron dermatitis. Warts and molluscum contagiosum lesions can be spread in linear patterns by self-scratching ("auto-inoculation"). Toxicodendron dermatitis lesions are often linear from brushing up against the plant. Causes of the Koebner phenomenon that are secondary to scratching rather than an infective or chemical cause include vitiligo, psoriasis, lichen planus, lichen nitidus, pityriasis rubra pilaris, and keratosis follicularis.
Cyclophoroidea is a superfamily of land snails with an operculum, terrestrial gastropods within the informal group Architaenioglossa, that belongs to the clade Caenogastropoda.
Oskar Simon was a German dermatologist who was a native of Berlin.
Superficial lymphatic malformation is a congenital malformation of the superficial lymphatics, presenting as groups of deep-seated, vesicle-like papules resembling frog spawn, at birth or shortly thereafter. Lymphangioma circumscriptum is the most common congenital lymphatic malformation. It is a benign condition and treatment is not required if the person who has it does not have symptoms from it.
Molluscum dermatitis represents a unique form of id reaction, in which patients may present with localized or widespread eczema surrounding scattered lesions of molluscum contagiosum.
British NVC community OV38 is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities of crevice, scree and spoil vegetation.
Ctenidium may refer to:
A ctenidium is a respiratory organ or gill which is found in many molluscs. This structure exists in bivalves, cephalopods, Polyplacophorans (chitons), and in aquatic gastropods such as freshwater snails and marine snails. Some aquatic gastropods possess one ctenidium known as monopectinate and others have a pair of ctenidia known as bipectinate.
Bryotropha dryadella is a moth of the family Gelechiidae. It is found in Great Britain, France, Portugal, Spain, Corsica, Sardinia, Sicily, Italy, Albania, North Macedonia, Bulgaria, Greece, Crete and Algeria.

Ctenidium is a genus of mosses belonging to the family Hypnaceae.
