An observational and descriptive study of the epidemiology of and therapeutic approach to onychomycosis in dermatology offices in Brazil.

BACKGROUND: Onychomycosis is a type of fungal infection that accounts for over 50% of all onycopathies. Some authors consider superficial mycosis the most difficult to be treated. Very few studies have been carried out in order to assess the epidemiology of onychomycosis in Brazil. OBJECTIVE: To describe the epidemiological profile of onychomycosis in Brazilian dermatology offices and to assess the etiology of the disease, how often mycosis exams are requested, and the treatment adopted. METHODS: A descriptive, observational study was carried out between May and July, 2010. Thirty-eight dermatologists from different Brazilian regions participated in the study, and 7,852 patients with any skin diseases who had all of their nails examined were included in the study. RESULTS: Of the 7,852 patients, 28.3% were clinically diagnosed as having onychomycosis. Women over 45 years old who practiced exercises or with a personal history of the disease showed greater likelihood of having onychomycosis. The disease was most seen in the feet, and the majority of cases involved the hallux. On the hands, the index finger was the most affected. Mycosis exams were not requested for all clinically suspected cases. When exams were done, results showed that the most common fungus was Trichophyton rubrum. The most common clinical lesion was distal-lateral. The most prescribed topical treatments were amorolfine and ciclopirox olamine, while systemic treatments included fluconazole and terbinafine. CONCLUSION: This study was important to describe the epidemiological behavior of onychomycosis in Brazilian dermatology offices and to determine important risk factors, such as gender, age, practice of exercises, personal history of the disease, and comorbidities.

Fundamentos: As onicomicoses são infecções fúngicas que representam mais de 50% de todas onicopatias e são consideradas por alguns autores a micose superficial de mais difícil tratamento. Poucos estudos foram feitos para investigar a epidemiologia da onicomicose no Brasil. Descrever perfil epidemiológico da onicomicose nos consultórios brasileiros de dermatologia. Também observar a etiologia, a freqüência da solicitação do exame micológico e a terapia empregada. Foi realizado um estudo descritivo e observacional no período de Maio a Julho de 2010. Participaram 38 dermatologistas de diferentes regiões do Brasil e foram incluídos 7852 pacientes. Dos 7852 pacientes, 28.3% apresentaram diagnóstico de onicomicose. Mulheres, maiores de 45 anos, praticantes de esportes, ou com histórico pessoal da doença, apresentaram chance maior de adquirir onicomicose. A doença foi mais frequente nos pés, sendo o hálux, o dedo mais acometido. Nas mãos, o primeiro dedo foi o mais atingido. Exame micológico não foi solicitado para todos os casos. Quando realizado, o fungo mais freqüente foi o Trichophyton rubrum. A lesão clinica mais comum foi a distal-lateral. Os tratamentos tópicos mais prescritos foram amorolfina e ciclopirox olamina, enquanto os sistêmicos foram o fluconazol e a terbinafina. Este estudo foi de fundamental importância para descrever o comportamento epidemiológico ...

Treatment of transverse overcurvature of the nail with a plastic device: measurement of response.

BACKGROUND: Transverse overcurvature of the nail is a painful condition that has been treated by conservative and/or surgical methods. OBJECTIVES: We sought to evaluate the efficacy of a plastic device for treatment of transverse overcurvature of the nail and to use a practical method (plaster mold) to evaluate follow-up of nail widening during and after treatment. METHODS: Twenty-five patients with transverse overcurvature of the nail were treated with placement of a plastic device. Pain assessment was done on a monthly basis. Nail improvement was evaluated through photographs and measurement of widening by plaster molds. RESULTS: Relief of pain could be determined in almost 100% of the cases in a 3-month period. Widening of overcurvature of the nail occurred in all cases. The plaster mold allowed a practical measurement of improvement in nail shape. CONCLUSION: The plastic device is an effective, safe, noninvasive, and inexpensive treatment option for overcurved nails. The plaster mold is a practical method to evaluate improvement in nail shape.
