[Papillary adenoma of type-II pneumocytes as a rare differential diagnosis of a solitary pulmonary nodule].

The case of a 66-year-old, asymptomatic patient with a papillary adenoma of type-II pneumocytes is reported. Following the coincidental radiologic finding of a solitary pulmonary nodule, the diagnosis could be established in a bronchoscopically obtained endobronchial biopsy. A resection of the involved segments S8-10 on the left side was performed.

[Risk assessment of patients before lung surgery].

Lung resection offers the best prospect of long-term survival in patients with nonmetastatic pulmonary neoplasia. In view of the dismal prognosis of unresected bronchial cancer, surgical resection should be encouraged even in patients with reduced cardiopulmonary function. Accurate estimation of the postoperative cardiopulmonary function is therefore desirable to avoid (a) refusal of potentially curative treatment and (b) severe postoperative disability.

[Flexible bronchoscopic implantation of Accuflex and Strecker stents in malignant bronchial stenoses].

Silicone and metal stents are available for the treatment of malignant bronchial stenoses. This project sought to compare the self-expanding nitinol Accuflex stent (Boston Scientific Corp; Watertown, Mass) with the passively expandable tantalum Strecker stent (Boston Scientific Corp; Watertown, Mass), both implanted by flexible bronchoscopy under local anesthesia and sedation. In 51 patients with malignant bronchial stenosis, 14 nitinol and 51 tantalum stents were used and stenoses of 75 to 100% were treated.

Bone mass and muscle strength in female college athletes (runners and swimmers).

Objective: To determine whether female college athletes had increased muscle strength and bone mass in comparison with age-matched nonathletic female subjects and, if so, whether participation in weight-bearing versus non-weight-bearing exercise made a difference.

Material And Methods: We performed a comparative statistical analysis of the bone mineral density (BMD) of the total body, lumbar spine, and femoral neck, maximal oxygen uptake (VO2max), muscle strength, and level of physical activity in 21 runners, 22 swimmers, and 20 control subjects. The study participants were female college students, 18 to 24 years old, who had had more than 8 normal menstrual cycles during the past year.
