[Bronchiolitis obliterans associated with Stevens-Johnson syndrome].

Stevens-Johnson syndrome is a severe disease which is characterized by fever and mucocutaneous lesions. It has also been described as a small airway compromise in the form of bronchiolitis obliterans. We report a 22-year-old male patient with Stevens-Johnson syndrome due to antibiotic and antiepileptic drug treatment for brain abscess.

[Alveolar hemorrhage as a complication of thrombolytic therapy].

Coronary thrombolysis is used as a strategy for coronary reperfusion for acute myocardial infarction. Bleeding is the main complication described. Although most of these events occur at sites of vascular access and are mild, in some cases gastrointestinal, retroperitoneal, genitourinary, lung and central nervous system bleeding may occur.

Pancreatic tuberculosis.

Pancreatic tuberculosis (TB) is a rare condition in immunocompetent patients and often represents a diagnostic challenge. Pancreatic TB may present with protean manifestations. Imaging with ultrasound, computed tomographic (CT) or endoscopic ultrasound (EUS) usually reveals multicystic pancreatic masses, most frequently in the head of the pancreas.

[Hyponatremia as a risk factor of death in patients with community-acquired pneumonia requiring hospitalization].

We investigated whether hyponatremia is a risk factor of death in patients hospitalized with community-acquired pneumonia (CAP) and estimated the relative risk of death by CAP of other risk factors. The design was prospective multicentre cohort study. In 5 centers in Buenos Aires, Argentina, we studied adults hospitalized with CAP between March 21, 2000 and December 21, 2000.
