Management of Common Fungal and Bacterial Skin Infections

Posted by e-Medical PPT Sunday, September 4, 2011
Dermatophytosis is a clinical condition caused by fungal infection of the skin in humans, pets such as cats, and domesticated animals such as sheep and cattle.The fungi that cause parasitic infection (dermatophytes) feed on keratin, the material found in the outer layer of skin, hair, and nails. These fungi thrive on skin that is warm and moist, but may also survive directly on the outsides of hair shafts or in their interiors.

    * Tinea pedis (athlete's foot) affects the feet
    * Tinea unguium affects the fingernails and toenails
    * Tinea corporis affects the arms, legs, and trunk
    * Tinea cruris (jock itch) affects the groin area
    * Tinea manuum affects the hands and palm area
    * Tinea capitis affects the scalp
    * Tinea barbae affects facial hair
    * Tinea faciei (face fungus) affects the face

Infections on the body may give rise to typical enlarging raised red rings of ringworm, infection on the skin of the feet may cause athlete's foot and in the groin jock itch.Involvement of the nails is termed onychomycosis, and they may thicken, discolour, and finally crumble and fall off.
Antifungal treatments include topical agents such as miconazole, terbinafine, clotrimazole, ketoconazole, or tolnaftate applied twice daily until symptoms resolve — usually within one or two weeks.Topical treatments should then be continued for a further 7 days after resolution of visible symptoms to prevent recurrence.
