Abstract: Mohs micrographic surgery is a technique used to excise skin tumors based on comprehensive surgical mapping, in which the surgeon removes the tumor, followed by a complete histological evaluation of the tumor's margins. The correlation of the presence of a tumor in histological examinations and its precise location on the surgical map result in a complete removal of the tumor with maximum normal tissue preservation. The present article seeks to provide general practitioners and healthcare specialists with guidelines regarding recommendations for Mohs micrographic surgery to treat skin tumors, based on the most reliable evidence available in medical literature on the subject. This bibliographic review of scientific articles in this line of research was conducted based on data collected from MEDLINE/PubMed. The search strategy used in this study was based on structured questions in the Patient, Intervention, Control, and Outcome (PICO) format. MeSH terms were used as descriptors. The indications of this technique are related to recurrence, histology, size, definition of tumor margins, and location of tumors. These guidelines attempt to establish the indications of Mohs surgery for different types of skin tumors.

Um surto de leptospirose humana por atividade recreacional ocorreu no município de São José dos Campos em novembro de 1987, envolvendo um grupo de pessoas que, ao participarem de uma festa de confraternização em um clube na periferia da cidade, banharam-se em uma piscina de água natural. Após a realização da investigação epidemiológica e laboratorial, observou-se alta prevalência do sorotipo pomona na análise sorológica (91%) e não se conseguiu isolar o agente etiológico nas amostras de água da piscina do clube. Os dados epidemiológicos e laboratoriais sugerem que a fonte de infecção tenha sido a água da piscina contaminada por dejetos de suínos e de outros animais domésticos dos locais adjacentes a água do córrego que alimentava a piscina do clube.

An outbreak of human leptospirosis due to recreational activities ocurred at São José dos Campos, São Paulo, Brazil in November 1987.
