Air-Leak Syndrome with Spontaneous Tension Pneumothorax and Pneumomediastinum Caused by Bleomycin-Induced Organizing Pneumonia.

The appearance of pneumatoceles in a patient with organizing pneumonia is an early sign of leak syndrome and is a significant finding as its rupture can lead to a life-threatening tension pneumothorax. Air leak syndrome (ALS), consisting of pneumothorax, subcutaneous emphysema and pneumomediastinum, is a rare complication of organizing pneumonia (OP). We report a case of a patient with bleomycin-induced OP who develops a tension pneumothorax due to a ruptured pneumatocele caused by ALS and correlate with histopathological analysis.

Thromboembolic complications of recreational nitrous oxide (ab)use: a systematic review.

The recreatinal use of nitrous oxide has become more common in recent years, especially in adolescents and young adults. It has been mainly associated with medical conditions like megaloblastic anemia and (myelo)neuropathy. We report on the thromboembolic complications, a less known side effect, associated with recreational inhalation of nitrous oxide.

Long-term outcome of transcatheter embolotherapy for acute lower gastrointestinal hemorrhage.

Objectives: We sought to assess the safety, short- and long-term efficacy, and durability of transcatheter embolization for lower gastrointestinal hemorrhage (LGH) unresponsive to endoscopic therapy and to analyze the overall survival of the embolized patients.

Methods: Between January 1997 and January 2008, 122 patients were referred for angiographic evaluation to control major LGH. Overall, 43 patients (35.
