Se presenta un caso de ruptura aneurismatica de la arteria esplenica intervenido con buen resultado. Son mas frecuentes en la mujer y pueden desarrollarse durante el embarazo. Sin embargo, una causa frecuente es la arterioesclerosis, como sucedio en el caso presentado. Asintomaticos antes de la ruptura pueden sin embargo causar dolor y ser sospechados por calcificaciones curvilineas en radiografias directas del abdomen o en el curso de otros estudios. La aortografia y la arteriografia del tronco celiaco confirmaran el diagnostico. Aunque la ruptura es infrecuente y en general depende de su tamano, la reposicion sanguinea adecuada y la cirugia de hemostasia o de exeresis podran salvar la vida del paciente

Sera of 155 chronic hepatitis (CH) patients in Argentina were tested for the presence of HBsAg, anti-HBs, anti-HBc, and anti-HAV. Our purpose was to define the role that both virus A and B might play in the etiology and pathogenesis of this condition. The patients were divided into two groups: group I (57) HBsAg-negative; group II (98) HBsAg-positive. The control group consisted of 1,209 healthy blood donors from Banco Central de Sangre de Rosario; 286/1,209 (24%) had viral markers for HBV. In group I, 38/57 (67%) had anti-HBs and/or anti-HBc, but none had anti-HBs alone. Group II showed a higher percentage of males (P less than 0.05). We found similar incidence of anti-HAV among group I, group II, and the control group.

156 patients with chronic hepatitis were studied in Rosario, Argentina. 98 patients were HBsAg positive (group I) and 58 patients were negative (group II). 209 normal volunteer blood donors served as controls (group III). In all cases the presence of anti-HAV was sought by RIA and was found in 92% of cases in group I, 91% in group II and 82% in group II patients. In groups II and III we also determined the presence of anti-HBcAg by RIA being positive in 65% and 15% respectively (p less than 0.01). There were no differences related to sex, age and type of chronic hepatitis. We conclude, firstly that the percentage of anti-HAV is similar in chronic hepatitis and healthy controls; secondly, that 65% of patients with HBsAg negative chronic hepatitis have evidence of virus B infection demonstrated by the presence of anti-HBcAg; finally we remark the greater sensitivity of RIA over hemmagglutination for the detection of anti-HBcAg.

253 percutaneous transhepatic cholangiographies with Chiba needle were performed. In 83% of the cases the biliary tract could be visualized. In the patients with extrahepatic cholestasis 92% success was achieved, while only 48% success in the cases with intra-hepatic cholestasis. Complications were developed in 3,87% of cases (choleperitoneum 4, cholangitis 2, hemorrhage 2, paralytic ileum 1, hemobilia 2). There was no mortality. Patients with dilated biliary tract should be operated upon in no more than 24 hours following the procedure.

RESUMO
Over a seven-year period, we monitored 221 patients with chronic hepatitis from two medical centers. By using the counterlectrophoresis (CEP) test to detect the presence of HBsAg and anti-HBc, or both, we established that 87.7% of them had hepatitis B infection. Serum specimens originally found negative for HBsAg by CEP were further tested by reversed passive hemagglutination (RPH), and those originally found negative for anti-HBc by CEP were further tested by radioimmunoassay (RIA). Five patients were anti-HBc-positive and HBs-Ag-negative. No sex predominance was observed, but HBsAg incidence increased with increasing age. The HBeAg antigen was detected in 46.8% of the 161 cases tested for it; the most frequent subtype found was adw (63.7%). The present findings indicate that HBV infection largely contributes to the development of chronic hepatitis in Argentinian patients.
