Autochtonal case of chronic, unifocal, pulmonary paracoccidioidomycosis with methotrexate use, in Salvador ‒ Brazil.

We report an autochthonous case of mild unifocal chronic pulmonary paracoccidioidomycosis in a 48-year-old previously healthy woman with no history of possible environmental exposures in endemic rural areas, supposedly resulting from reactivation of a latent pulmonary focus secondary to the use of methotrexate for the control of Chikungunya arthropathy. Laboratory investigation ruled out other immunosuppression. Her only symptoms were a dry cough and chest pain. Diagnosis confirmed by needle lung biopsy. There were no abnormalities on physical examination nor evidence of central nervous system involvement. MRI of the total abdomen showed no involvement of other organs. Computed chest tomography showed a favorable evolution under the use of itraconazole (200 mg/day). Different tomographic presentations findings are highlighted when performed before and after treatment. CONCLUSIONS: PCM should be considered even in a woman without a history of consistent environmental exposure and in a non-endemic geographic area.

Abstract Summary We report an autochthonous case of mild unifocal chronic pulmonary paracoccidioidomycosis in a 48-year-old previously healthy woman with no history of possible environmental exposures in endemic rural areas, supposedly resulting from reactivation of a latent pulmonary focus secondary to the use of methotrexate for the control of Chikungunya arthropathy. Laboratory investigation ruled out other immunosuppression. Her only symptoms were a dry cough and chest pain. Diagnosis confirmed by needle lung biopsy. There were no abnormalities on physical examination nor evidence of central nervous system involvement. MRI of the total abdomen showed no involvement of other organs. Computed chest tomography showed a favorable evolution under the use of itraconazole (200 mg/day).

Brazilian guidelines for community-acquired pneumonia in immunocompetent adults - 2009.

Community-acquired pneumonia continues to be the acute infectious disease that has the greatest medical and social impact regarding morbidity and treatment costs. Children and the elderly are more susceptible to severe complications, thereby justifying the fact that the prevention measures adopted have focused on these age brackets. Despite the advances in the knowledge of etiology and physiopathology, as well as the improvement in preliminary clinical and therapeutic methods, various questions merit further investigation. This is due to the clinical, social, demographical and structural diversity, which cannot be fully predicted. Consequently, guidelines are published in order to compile the most recent knowledge in a systematic way and to promote the rational use of that knowledge in medical practice. Therefore, guidelines are not a rigid set of rules that must be followed, but first and foremost a tool to be used in a critical way, bearing in mind the variability of biological and human responses within their individual and social contexts. This document represents the conclusion of a detailed discussion among the members of the Scientific Board and Respiratory Infection Committee of the Brazilian Thoracic Association. The objective of the work group was to present relevant topics in order to update the previous guidelines. We attempted to avoid the repetition of consensual concepts. The principal objective of creating this document was to present a compilation of the recent advances published in the literature and, consequently, to contribute to improving the quality of the medical care provided to immunocompetent adult patients with community-acquired pneumonia.

Diretrizes brasileiras para pneumonia adquirida na comunidade em adultos imunocompetentes - 2009 / Brazilian guidelines for community-acquired pneumonia in immunocompetent adults - 2009

A pneumonia adquirida na comunidade mantém-se como a doença infecciosa aguda de maior impacto médico-social quanto à morbidade e a custos relacionados ao tratamento. Os grupos etários mais suscetíveis de complicações graves situam-se entre os extremos de idade, fato que tem justificado a adoção de medidas de prevenção dirigidas a esses estratos populacionais. Apesar do avanço no conhecimento no campo da etiologia e da fisiopatologia, assim como no aperfeiçoamento dos métodos propedêuticos e terapêuticos, inúmeros pontos merecem ainda investigação adicional. Isto se deve à diversidade clínica, social, demográfica e estrutural, que são tópicos que não podem ser previstos em sua totalidade. Dessa forma, a publicação de diretrizes visa agrupar de maneira sistematizada o conhecimento atualizado e propor sua aplicação racional na prática médica. Não se trata, portanto, de uma regra rígida a ser seguida, mas, antes, de uma ferramenta para ser utilizada de forma crítica, tendo em vista a variabilidade da resposta biológica e do ser humano, no seu contexto individual e social. Esta diretriz constitui o resultado de uma discussão ampla entre os membros do Conselho Científico e da Comissão de Infecções Respiratórias da Sociedade Brasileira de Pneumologia e Tisiologia. O grupo de trabalho propôs-se a apresentar tópicos considerados relevantes, visando a uma atualização da diretriz anterior. Evitou-se, tanto quanto possível, uma repetição dos conceitos considerados consensuais. O objetivo principal do documento é a apresentação organizada dos avanços proporcionados pela literatura recente e, desta forma, contribuir para a melhora da assistência ao paciente adulto imunocompetente portador de pneumonia adquirida na comunidade.

Traquéia em bainha de sabre ("saber-sheath trachea"): correlaçäo clínico-tomográfico-endoscópico-funcional / Saber-sheath trachea: clinic-tomographic-endoscopic-functional correlation

A traquéia em bainha de sabre constitui um distúrbio morfofuncional do segmento intratorácico, caracterizado pela configuraçäo anormal das cartilagens traqueais, em que o diâmetro lateral representa menos de 2/3 do ântero-posterior, com estreitamento do arco anterior e colapso das paredes laterais durante a tosse e expiraçäo forçada. Assim como na forma semilunar da síndrome de colapso expiratório da traquéia, ela é mais freqüente em portadores de DPOC, quando o quadro clínico-radiológico costuma subestimar a gravidade do distúrbio funcional. Os autores demonstram a correlaçäo clínico-tomográfico-endoscópio-funcional no caso de uma paciente com 43 anos de idade, portadora de insuficiência respiratória crônica...
