Common Tinea Infections in Children - Article

ABSTRACT: The common dermatophyte genera Trichophyton, Microsporum, and Epidermophyton are major causes of superficial fungal infections in children. These infections (e.g., tinea corporis, pedis, cruris, and unguium) are typically acquired directly from contact with infected humans or animals or indirectly from exposure to contaminated soil or fomites. A diagnosis usually can be made with a focused history, physical examination, and potassium hydroxide microscopy. Occasionally, Wood's lamp examination, fungal culture, or histologic tissue examination is required. Most tinea infections can be managed with topical therapies; oral treatment is reserved for tinea capitis, severe tinea pedis, and tinea unguium. Topical therapy with fungicidal allylamines may have slightly higher cure rates and shorter treatment courses than with fungistatic azoles. Although oral griseofulvin has been the standard treatment for tinea capitis, newer oral antifungal agents such as terbinafine, itraconazole, and fluconazole are effective, safe, and have shorter treatment courses.


Seborrheic Dermatitis: An Overview - Article

ABSTRACT: Seborrheic dermatitis affects the scalp, central face, and anterior chest. In adolescents and adults, it often presents as scalp scaling (dandruff). Seborrheic dermatitis also may cause mild to marked erythema of the nasolabial fold, often with scaling. Stress can cause flare-ups. The scales are greasy, not dry, as commonly thought. An uncommon generalized form in infants may be linked to immunodeficiencies. Topical therapy primarily consists of antifungal agents and low-potency steroids. New topical calcineurin inhibitors (immunomodulators) sometimes are administered.


Diagnosis and Management of Common Tinea Infections - Article

ABSTRACT: The estimated lifetime risk of acquiring a dermatophyte infection is between 10 and 20 percent. Recognition and appropriate treatment of these infections reduces both morbidity and discomfort and lessens the possibility of transmission. Dermatophyte infections are classified according to the affected body site, such as tinea capitis (scalp), tinea barbae (beard area), tinea corporis (skin other than bearded area, scalp, groin, hands or feet), tinea cruris (groin, perineum and perineal areas), tinea pedis (feet), tinea manuum (hands) and tinea unguium (nails). To determine the best treatment approach, the physician must consider several factors: (1) the anatomic locations of the infection, (2) the safety, efficacy and cost of treatment options and (3) the likelihood that the patient will comply with treatment. Newer medications in both oral and topical forms, including imidazoles and allylamines, have greatly increased the cure rate for tinea infections. Certain types of tinea may be treated with "pulse" regimens; these innovative therapies lower treatment costs and improve patient compliance.


Diagnosis of Vaginitis - Article

ABSTRACT: Vaginitis is the most common gynecologic diagnosis in the primary care setting. In approximately 90 percent of affected women, this condition occurs secondary to bacterial vaginosis, vulvovaginal candidiasis or trichomoniasis. Vaginitis develops when the vaginal flora has been altered by introduction of a pathogen or by changes in the vaginal environment that allow pathogens to proliferate. The evaluation of vaginitis requires a directed history and physical examination, with focus on the site of involvement and the characteristics of the vaginal discharge. The laboratory evaluation includes microscopic examination of a saline wet-mount preparation and a potassium hydroxide preparation, a litmus test for the pH of vaginal secretions and a "whiff" test. Metronidazole is the primary treatment for bacterial vaginosis and trichomoniasis. Topical antifungal agents are the first-line treatments for candidal vaginitis.
