Onychomycosis - diseases of the nails, caused by various pathogenic fungi - epidermofitony, Trichophyton, forename, rarely, yeast-like fungi of the genus Candida, mold. Fungi are found in nail scrapings from direct microscopy or culture. The emergence of onychomycosis promote micro-injuries, maceration, disturbance of trophism. Onychomycosis is often combined with fungal diseases of the skin (see) and hair. There are three types of onychomycosis: 1) surface - on nails appear yellowish-white spots and stripes, soften the nail plate, usually amazed 1 to 2 finger; 2) invasive type - the defeat of more generalised, nail plate dull, brittle, thickened; 3) be accompanied type - against the progression of the above phenomena is observed subungual hyperkeratosis, nail pulling away from the bed, deformed.
Treatment: griseofulvin, nystatin - depending on the type of pathogen (see Candidiasis, Trichophytosis, Athlete's foot). Surgical removal of the affected nails, scraping nail plates after softening hot adowymi trays (2 tea spoons of baking soda in 1 glass of water) or delete them with keratolytic patches, such as ureaplasmal and others (on prescription), with the subsequent imposition of fungicidal plasters, disinfectant: 5-10% sulfur-tar ointment, 2% iodine tincture and other

Onychomycosis (onychomycosis; from the Greek. onyx, onychos - nail and mykes - fungus)- nails diseases of the hands and feet caused by fungi of the genera Trichophyton, Achorion, Epidermophyton and Candida, rarely moulds. The affected nail deformed becomes dull, thickens, then crumble. In trihofitii nails have a dirty grey, when pause, plicarum, rubrofitia - yellow, with candidiasis - brown-brown color. Onychomycosis is accompanied by a fungal infection of the skin of the fingers, palms, soles, candidiasis nail - candicemichelle the paronychia. In the pathogenesis of the Acting main role is played by the injury. The importance of Acting in the epidemiology of fungal infections as a reservoir of infection.
Microscopically in the scrapings from the nail find threads and fungus spores. The most effective (except in cases of candidiasis) treatment grizeofulvinom (see) the removal of nails through the re-imposition of keratolytic of ointments and plasters containing urea (20%) or salicylic acid (50%), as well as with the treatment of Mycobacterium skin of the fingers, palms, soles. Apply the following method of detachment: on the affected area impose on two days a bandage with ointment [Acidi salicylici - 4,0; Acidi laetici (s. Acidi benzoici) - 2,0; Yaselini - 24,0], cover with wax paper and tape up or attach collodion or leukoplastom, then on the day - vaseline bandage and again for two days - the above ointment. The outer layer is separated by large reservoirs. Further treatment - lubricating 2% iodine tincture and rubbing 10 - 15% sulfur-tar ointment. In the treatment of onychomycosis bandage impose 4-5 times, which leads to a softening of the nail plate; then it is separated with a scalpel from the nail bed, cut with scissors along and removed with tweezers both halves; treatment nail bed continue the same ointment.
