Multicenter Study Comparative Study
Use of studded Polyflex stents in patients with neoplastic obstructions of the central airways.
The Polyflex is a commercially available silastic airway stent with proven efficacy. Due to a smooth outer surface its anchorage in the airway wall is superficial which may lead to stent migration. ⋯ The studded Polyflex showed excellent efficacy, was very well tolerated, and had a very low migration rate. It presents an improvement over the older smooth model and can be considered a true alternative to the most widely used silastic stent, the Dumon stent.

Comparative Study
Clinical validity of negative helical computed tomography for clinical suspicion of pulmonary embolism.
Helical computed tomography has been introduced for the diagnosis of pulmonary embolism. ⋯ In patients with clinical suspicion of pulmonary embolism and initial negative helical computed tomography from whom anticoagulants are withheld, no thromboembolic disease was detected in a 3-month follow-up. We consider helical computed tomography an effective method for ruling out pulmonary embolism as well as a front-line tool for diagnosis.

Case Reports
An unusual case of bronchiolitis obliterans organizing pneumonia concomitant with bronchioloalveolar carcinoma.
Although bronchiolitis obliterans organizing pneumonia (BOOP) has been associated with a variety of underlying disorders, the majority of cases of BOOP are idiopathic. We present the case of a 61-year-old patient with fever, dry cough, bilateral patchy consolidation and high erythrocyte sedimentation rate. Open lung biopsy shows coexistence of BOOP and bronchioloalveolar carcinoma. It is interesting that both diseases are predominantly air space diseases and present similar radiologic features making the diagnosis and follow-up of treatment more difficult.
