A study was conducted in São Paulo, Brazil, to compare azithromycin with thiamphenicol for the single-dose treatment of chancroid. In all, 54 men with chancroid were tested. The etiology was determined by clinical characterization and direct bacterioscopy with Gram staining. None of the patients had positive serology or dark-field examination indicating active infection with Treponema pallidum. Genital infections due to Neisseria gonorrhoeae and herpes simplex virus were excluded by polymerase chain reaction testing. For 54 patients with chancroid, cure rates with single-dose treatment were 73% with azithromycin and 89% with thiamphenicol. HIV seropositivity was found to be associated with treatment failure (p=0.001). The treatment failed in all HIV positive patients treated with azithromycin (p=0.002) and this drug should be avoided in these co-infected patients. In the view of the authors, thiamphenicol is the most indicated single-dose regimen for chancroid treatment.

FUNDAMENTOS: A observação de lesões cutâneas é freqüente pelos indivíduos que as têm e por seus familiares. A demanda de pacientes que buscam atenção médica com queixas cutâneas é significante. OBJETIVO: Determinar a freqüência das alterações dermatológicas em usuários do Sistema Único de Saúde de Campinas, Estado de São Paulo, Brasil. MÉTODOS: Cinco unidades básicas de saúde foram selecionadas pela Secretaria de Saúde da Prefeitura Municipal para participar da pesquisa. Todos os pacientes atendidos por profissionais de saúde dessas unidades, no período de 20 dias úteis, deveriam ser avaliados quanto à presença ou ausência de sintomas/sinais dermatológicos. RESULTADOS: Dos 1.491 pacientes avaliados, 358 (24,01%) apresentavam queixas e/ou achados dermatológicos, com maior prevalência nos mais jovens. De todos os usuários atendidos pelos profissionais de saúde que participaram do estudo e que tiveram as fichas preenchidas adequadamente, 9,98% procuraram a Unidade Básica de Saúde primariamente pela queixa dermatológica. CONCLUSÃO: Esses resultados, condizentes com estudos semelhantes realizados em outros países, mostram a importância da especialidade para o desempenho do médico não dermatologista, especialmente dos pediatras, e dão elementos para a discussão curricular sobre a suficiência do tempo destinado ao ensino da especialidade no curso médico.

BACKGROUND: Skin lesions are often noted by the individuals bearing them, as well as by their relatives. There is a significant number of patients with skin complaints who search for medical care. OBJECTIVES: To determine the frequency of dermatological complaints and/or findings in users of the primary health care system of the city of Campinas, Brazil. METHODS: Five units were chosen by the Municipal Health Department to participate in this research. All the patients assisted by health professionals of these units were evaluated regarding the presence or absence of dermatological symptoms/ signals in a time period of twenty working days. RESULTS: The acquired data demonstrated that 358 (24.01%) out of 1,491 assisted patients displayed dermatological complaints and/or findings, with a greater prevalence among the younger patients. Of all the users assisted by health professionals who participated in the study and had their records adequately filled out, 9.98% sought the primary care unit primarily because of a dermatological complaint. CONCLUSIONS: These results, in accordance to those of similar surveys carried out in other countries, show the importance of the specialty for the performance of non-dermatologist physicians, pediatricians in particular, and provide elements for the discussion surrounding the curricular reform, concerning the amount of time dedicated to the teaching of dermatology.
