Objective: Behcet's syndrome, or Behcet's disease (BD), is a multisystem pathology, and survival is related to pulmonary involvement. However, it appears that different treatments correlate with different prognoses. The aim of this study was to evaluate clinical and tomographic evolution, as well as the survival, of patients with BD-related pulmonary involvement. Methods: A retrospective review of our experience with pulmonary manifestations in patients with BD treated at our institution between January 1, 1988 and April 30, 2006. The clinical, radiological, treatment and survival data were obtained from medical charts. Results: We identified 9 patients with BD-related pulmonary involvement. The mean age was 34 ± 11.5 years, and 7 of the patients were male. The radiological findings were as follows: pulmonary artery aneurysm (PAA) in 8 patients; pulmonary embolism in 3 (translating to an incidence of 5.11 cases/100 patient-years); alveolar hemorrhage in one; and pulmonary hypertension in one. The treatment consisted of immunosuppression with prednisone plus chlorambucil (or cyclophosphamide or mycophenolate mofetil) in all patients, with partial or complete resolution of the PAAs. One patient with a PAA and pulmonary hypertension also received sildenafil and warfarin, with good clinical and tomographic response (the first report in the English literature). In our sample, the mean duration of the follow-up period was 6.52 years. The three-year survival rate was 88.8%, as was the five-year survival rate. Conclusions: Patients with BD-related pulmonary involvement can present good survival with immunosuppressive therapy, and BD should be borne in mind as a possible cause of pulmonary hypertension and alveolar hemorrhage.

Objective: To investigate the incidence of asthma symptoms in young amateur swimmers, and to describe the clinical treatment of the children with asthma in a private sports club in the city of São Paulo, Brazil. Methods: The study included 171 amateur swimmers, ranging from 6 to14 years of age. All of the participants or their legal guardians were asked to complete the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire, and 119 were submitted to pulmonary function testing at rest. Results: The overall incidence of asthma symptoms (ISAAC score ≥ 6) among the swimmers was 16.8%. Of the 119 swimmers submitted to spirometry, 39 (32.7%) presented spirometric alterations (FEV1/FVC < 0.75). Among those with an ISAAC score ≥ 6, there were 10 (31.2%) who stated that they were receiving no asthma treatment. Of those who reported receiving pharmacological treatment, 24% made use of bronchodilators but not of corticosteroids. Conclusions: The incidence of asthma symptoms and pulmonary function alterations among amateur swimmers within the 6-14 age bracket was high. In addition, a relevant proportion of these athletes were receiving no treatment.
