A review of bush dog Speothos venaticus (Lund, 1842) (Carnivora, Canidae) occurrences in Paraná state, subtropical Brazil / Revisão dos registros de ocorrência do cachorro-do-mato-vinagre Speothos venaticus (Lund, 1842) (Carnivora, Canidae), no Estado do Paraná, Brasil Subtropical

Abstract We report six new occurrence records of the bush dog Speothos venaticus, a widely distributed South American carnivore that is threatened with extinction. These records are accompanied by notes on the places where the records were made, such as vegetation type, date and information about the protection of areas. The records, obtained over the last 17 years in Paraná state, southern Brazil, offer an improved understanding of the species geographic range and the threats it faces and can enable better assessments of the conservation status of the species in southern Brazil.

Resumo Apresentamos seis novos registros de ocorrência do cachorro-do-mato-vinagre Speothos venaticus, um carnívoro sul Americano de ampla distribuição geográfica, porém ameaçado de extinção. Os registros são acompanhados de notas sobre os locais onde foram obtidos, tais como: tipo de vegetação, datas e informações sobre a proteção das áreas. Os registros, obtidos ao longo dos últimos 17 anos no Estado do Paraná, na região sul do Brasil, oferecem uma maior compreensão acerca da distribuição geográfica e das ameaças que a espécie enfrenta, permitindo melhores avaliações sobre o status de conservação desta espécie no sul do Brasil.

Use of aspiration method for collecting brain samples for rabies diagnosis in small wild animals.

In developing countries such as Brazil, where canine rabies is still a considerable problem, samples from wildlife species are infrequently collected and submitted for screening for rabies. A collaborative study was established involving environmental biologists and veterinarians for rabies epidemiological research in a specific ecological area located at the Sao Paulo State, Brazil. The wild animals' brains are required to be collected without skull damage because the skull's measurements are important in the identification of the captured animal species. For this purpose, samples from bats and small mammals were collected using an aspiration method by inserting a plastic pipette into the brain through the magnum foramen. While there is a progressive increase in the use of the plastic pipette technique in various studies undertaken, it is also appreciated that this method could foster collaborative research between wildlife scientists and rabies epidemiologists thus improving rabies surveillance.

Aspectos evolutivos do nevo sebaceo de Jadassohn. / Evolutive aspects of sebaceous nevus of Jadassohn

Procedeu-se a revisao e analise de 41 casos de nevo sebaceo de Jadassohn quanto a sua evolucao. A casuistica apresentou tres estadios: o pre-pubertario, o pos-pubertario e o adulto. Evidenciou-se atrofia de pelos e glandulas sebaceas, hiperplasia e maturacao de glandulas sebaceas e apocrinas, alem de implantacao de tumores benignos e malignos.Comenta-se o prognostico e o tratamento desses tumores

Atrofodermia idiopatica progressiva (Pasini-Pierini) e os estados esclero-atroficos. / Pasini-Pierini's progressive idiopathic atrophodermia and the sclero-atrophic states

A proposito de um caso de atrofodermia idiopatica de Pasini-Pierini, entidade de nosologia ainda indefinida, discutem-se os chamados estados esclero-atroficos, objetivando interpreta-los sob o ponto de vista clinico-patologico, quer como entidades autonomas, afins ou superponiveis

[The value of radiotomographic examination in carcinomas of the larynx (author's transl)]. / La valeur de l'examen radio-tomographique dans les carcinomes du larynx.

The autors compare the interpretation of radiotomographic films and the results of pathological examination of total laryngectomy specimens in 60 cases without contrast and in 15 cases with contrast. They study the value of the interpretation of X-ray films according to the site in terms of height, size, shape, the extent of the carcinoma and possible involvement of the pre-epiglottic space, the thyroid cartilage and the base of the tongue. With the aim of determining the true value of radiotomographic examination in carcinoma of the larynx, comparative tables were drawn up between the radiological interpretation and findings on macroscopic examination of total laryngectomy operative specimens. Radiological examination included standard lateral films, AP tomograms and, more recently, contrast laryngography.

Ewing's sarcoma of the mandible.

Ewing's sarcoma of the head and neck, particularly of the mandible, has a low incidence of occurrence (fifty-five cases in the literature). The present case report demonstrates well the clinical, diagnostic, and therapeutic features in a patient treated at the Head and Neck Service of the Fundação Antonio Prudente, São Paulo, Brazil. The etiologic, clinical, histopathologic, and radiologic features are discussed, with the conclusion that radiation is the best therapeutic procedure when associated with chemotherapy.
