Tinea Capitis: Fluconazole in Trichophyton tonsurans Infection

Abstract: Tinea capitis is the most common dermatophyte infection in children. Trichophyton tonsurans is the most common etiologic agent in the United States, and for more than four decades the standard therapy has been griseofulvin. The availability of newer, and often more effective, antifungal drugs creates the opportunity for choice and the ability to optimally tailor treatment for a particular patient. Fluconazole is an azole antifungal drug available in a pleasant, well-tolerated, liquid formulation ideal for the pediatric population. It has a good safety profile and is approved in the United States for use in children, although not for tinea capitis. We present five patients with tinea capitis successfully treated with fluconazole.     

Recent updates in oral terbinafine: its use in onychomycosis and tinea capitis in the US

Onychomycosis and tinea capitis are prevalent fungal diseases that are difficult to cure and usually require systemic treatment. Onychomycosis has high recurrence rates and can significantly affect a patient's quality of life. Oral terbinafine has been approved for onychomycosis for 20 years in Europe and 15 years in the United States. Over these past 20 years, numerous studies show that oral terbinafine is a safe and efficacious treatment for onychomycosis. More recently, oral terbinafine also has been approved for tinea capitis. Once difficult to treat, terbinafine has revolutionised treatment of these fungal diseases. It has minimal side effects and its limited drug interactions make it an excellent treatment option for patients with co-morbidities. This review discusses oral terbinafine and new insights into the treatment of onychomycosis and tinea capitis. Recent publications have enhanced our knowledge of the mechanisms of oral terbinafine and its efficacy in treating onychomycosis. Oral terbinafine vs. other antifungal therapeutic options are reviewed. Overall, terbinafine remains a superior treatment for dermatophyte infections because of its safety, fungicidal profile, once daily dosing, and its ability to penetrate the stratum corneum.     

Human polyomavirus‐7–associated eruption successfully treated with acitretin

Advances in molecular technologies have led to the discovery of several novel human polyomaviruses (HPyVs), including human polyomavirus‐7 (HPyV‐7). Although low levels of HPyV‐7 are shed from apparently normal skin, recent reports have described clinically significant cutaneous infection in immunocompromised patients that manifests as generalized pruritic plaques. The pruritus can be severe, and treatment options have not been described. Herein we report HPyV‐7 cutaneous infection in a heart transplant patient who experienced temporary improvement with intravenous cidofovir, and complete remission with acitretin. We report a case of HPyV‐7 cutaneous infection demonstrating a good response to treatment.
