Paraneoplastic syndromes are disorders of host organ function occurring at a site remote from the primary tumor and its metastases. Paraneoplastic syndromes associated with primary lung cancer are not uncommon, have diverse initial manifestations, and epitomize the systemic nature of human malignant disease. ⋯ Although diagnosis is often one of exclusion, improved understanding of the pathogenesis involved in some of these syndromes has provided another means of recognizing these disorders and perhaps treating affected patients. In this update, we review paraneoplastic syndromes associated with lung cancer, potential mechanisms, clinical manifestations, diagnosis, and treatment.

Multicenter Study
[Penetrating cardiac trauma. A nine-years experience in Cancún, Mexico].
Early patient intubations, rapid transportation, thoracotomy in the emergency room, and tamponade are the main reasons why patients with cardiac trauma survive at present. This paper describes the experience with cardiac trauma in Cancun, Quintana Roo, Mexico, during period of 9 years by general surgeons. ⋯ Cardiac trauma presents in a wide range of clinical situations. Tamponade was observed as a positive prognostic factor, mortality was due to principally lesions caused by firearms and to ascending aorta trauma. Extracorporeal circulation pump is rarely required.
