Diagnóstico e estadiamento do câncer de pulmão Diagnosis and staging of lung cancer
O câncer do pulmão pode apresentar-se sob diversas formas e vários são os meios de diagnosticá-lo. A escolha do melhor método para o seu diagnóstico depende de diferentes aspectos relacionados ao tumor, ao paciente e à habilidade da equipe médica. Dentre os métodos mais comumente utilizados para o diagnóstico do câncer do pulmão, podemos contar, além dos exames radiológicos, que não serão abordados neste artigo, a citologia do escarro, a broncofibroscopia, a punção aspirativa transtorácica e a toracoscopia, entre outros. O estadiamento reflete a extensão anatômica do câncer. As regras de estadiamento propostas por Denoix foram adaptadas de maneira satisfatória para o câncer do pulmão e, embora tenham sofrido diversas modificações, devidas ao avanço tecnológico dos métodos de diagnóstico, são importantes para orientar o tratamento e estimar o prognóstico. Com o advento de novas modalidades de tratamento, principalmente as combinadas, o estadiamento tende a assumir importância cada vez maior, tanto na escolha da modalidade terapêutica mais adequada quanto na comparação dos resultados.<br>Carcinoma of the lung can present in a number of guises and a number of possible and often complementary diagnostic approaches are available. The choice of procedure should reflect the presentation of the tumor, local expertise, intended management and patient preference. There are different methods of investigation: sputum cytology, fiberbronchoscopy, transbronchial biopsy, transbronchial needle aspiration, transthoracic fine needle aspiration, etc. The association of all of these methods increases the power of diagnosis. Staging is the measurement of the anatomical extent of a tumor in any given patient. The staging of cancer began with Denoix's TNM classification system, and, although several modifications were developed, it remains the basis of lung cancer staging systems up to now. Assigning patients to a particular TNM stage allows choosing the most appropriate therapy and provides prognostic information. Also, the impact of new therapeutic methods can be evaluated for efficacy and a comparison of the expected survival rates can be predicted
Bite injuries to the hand: microbiology, virology and management.
Bites to the human hand, be it from a pet, a stray animal or even a fellow human, may often have dire consequences for the person suffering the insult. Bites by mammals are a common problem and they account for up to 1% of all visits to hospital emergency rooms, in the UK. Clenched fist injuries to the mouth ('fight bite') are notorious for being the worst human bites. Bite injuries of the hand and their related infections must be monitored vigilantly and managed proactively, by experts in this field of surgery. In this review article we discuss the associated microbiology and virology of these injuries as well as their management
