ABSTRACT
O adenoma alveolar é uma neoplasia benigna rara dos pulmões, com poucos casos descritos na literatura. Freqüentemente, o paciente é assintomático e apresenta-se com um achado acidental em telerradiografias de tórax de um nódulo solitário e bem circunscrito. O diagnóstico definitivo é histológico e o tratamento consiste na ressecção cirúrgica do nódulo.
Alveolar adenoma is a rare benign neoplasm of the lungs, and very few cases have been described in the literature. Patients with alveolar adenoma are frequently asymptomatic and are diagnosed through the accidental discovery of a singular, well-delineated nodule on a routine chest X-ray. The definitive diagnosis is made histologically, and the treatment consists of surgical resection of the nodule.

O padrão de múltiplas lesões pulmonares é uma apresentação radiológica comum em pessoas infectadas pelo HIV. As causas possíveis para este podem ser divididas dentro de duas categorias: infecções e neoplasias. Os autores descrevem o caso de um paciente de 53 anos de idade com carcinoma adenóide cístico de nasofaringe, múltiplos nódulos pulmonares e infecção pelo HIV

In the skin, the concept of reperfusion injury is well established. The application of this knowledge to deal with skin flap surgery problems, has a great prophylactic potential. This experimental study was performed to evaluate the action of mannitol as a scavenger of oxygen-free radicals, after an ischemia-reperfusion injury on skin island flaps. Thirty six male Wistar rats were divided into three test groups (n = 12): a non-ischemic group (group I), and two others (groups II and III) which were subjected to nine hours of ischemia following by 30 minutes of reperfusion. After seven days, all animals of group II, treated with saline, showed full skin flap necrosis. The assessment of group III, that received a 20 percent solution of mannitol prior to the onset of reperfusion, revealed 75 percent (9/12) of flap viability. These results suggest that pre-treatment with mannitol is able to enhance flaps survival with significantly less tissue necrosis (p<0.02)

O caso de um paciente com quatro cânceres sincrônicos e metacrônicos do cólon é apresentado seguindo-se de uma revisäo sucinta da literatura. A sobrevida de cinco anos dos pacientes portadores de cânceres múltiplos submetidos a operaçöes curativas é a mesma dos pacientes tratados com câncer colorretal em geral. A colonoscopia é um exame excelente para diagnosticar os tumores múltiplos e deveria ser usada no pré-operatório ou durante a operaçäo
