RESUMEN
Spontaneous retroperitoneal hematoma is a rare condition. We report a 78 year-old man with progressive pain in his right thigh and hip lasting one week. The pain subsequently was associated with abdominal pain in the right lower quadrant. Physical examination revealed pain to deep palpation of the area, associated with a diffuse positive rebound pain. An abdominal and pelvis CT scan showed an extensive mesenteric hematoma. During surgery, a large retroperitoneal encapsulated hematoma, without evidence of active bleeding, was found and drained. Pathology confirmed the diagnosis and was negative for cancer.

Mediastinum hemangioma is a rare benign tumor. We performed surgery and present the first reported case in Chile. The patient is a 24-year-old symptomatic woman, referred to our hospital from a rural health center. The patient had all routine preoperative studies, chest radiographs and computed tomography of the thorax. We performed a median sternotomy with a complete resection of the mass. During the 36-month follow-up, she was well, asymptomatic and without relapse evidence. A review of the most outstanding characteristics of this rare tumor is presented.

The majority of patients with hepatitis A have a benign course, but some may develop fulminant hepatitis and hematological complications. Peripheral stem cell transplantation (PSCT) is associated with loss of immunity. There are no data regarding loss of HAV antibodies (anti-HAV) after PSCT. We retrospectively evaluated the persistence of anti-HAV in a nonvaccinated population that underwent PSCT. Serum detection of anti-HAV was determined before and after PSCT using a qualitative commercially available enzyme immunoassay. From January 1997 to March 2001, 136 (68%) of 201 patients tested (+) for anti-HAV prior to PSCT. Subsequent investigation of anti-HAV was possible in 36 of these patients at a median of 12 months after PSCT. The median age of patients was 47 years old; they had diagnoses of hematological malignancies (33) and solid tumors (three), and underwent autologous (31) and allogenic (five) PSCT. A total of 31 (86%) of 36 patients remained anti-HAV (+) and five (14%) became (-) after PSCT. The variables age, sex, diagnosis, type of PSCT, time of testing, and number of CD34 cells infused were not predictors of loss of anti-HAV. In conclusion, 14% of 36 nonvaccinated anti-HAV (+) patients lost their antibodies at a median of 12 months after PSCT.

Se estudiaran 41 lactantes con el diagnostico de otitis media aguda. Streptococcus pneumoniae fue el agente mas frecuente aislado (48,8%). Haemophilus influenzae se aislo como segunda etilogia. La parecentesis esta indicada en casos muy especificos y el pediatra general puede prescindir de ella en la mayoria de ellos. Conociendo las posibilidades etiologicas del cuadro se puede elegir una terapia adecuada
