[Hemoperitoneum as the form of presentation of hepatocellular carcinoma. The contribution of computed tomography to the diagnosis]. / Hemoperitoneu como forma de apresentação de carcinoma hepatocelular. Contributo da Tomografia Computorizada para o diagnóstico.

Haemoperitoneum following rupture of hepatocellular carcinoma (HCC) is unusual. Two patients with secondary massive intraperitoneal haemorrhage due to spontaneous rupture of HCC diagnosed by Computed Tomography (TC) are discussed. The most important clinical and imagiological features of this pathology are presented.

[Primary hyperaldosteronism: report of 2 clinical cases]. / Hiperaldosteronismo primário--a propósito de dois casos clínicos.

The authors report two cases of primary hyperaldosteronism (Conn's adenoma and hyperplasia). Based on available data, the authors discuss clinical laboratory and imagiologic evaluation, the factors influencing prognosis, strategy and the results of the proposed therapies.

[Streptococcus bovis endocarditis and colonic involvement]. / Endocardite a Streptococcus bovis e envolvimento do cólon.

McNeal and Blevins published the first report of Streptococcus bovis infective endocarditis in 1945. In 1951, McCoy suggested, for the first time, that an association could exist between Group D Streptococcus infective endocarditis and colon carcinoma; this association would be demonstrated later (1977) by Klein and unquestionably confirmed by several posterior works. Due to a clinical case of Streptococcus bovis infective endocarditis, which we had the opportunity of diagnosing, a review is made of the existent literature about the association between infection by this agent and the presence of lesions in the colon. Some recommendations are made in what respects the diagnosis and evaluation of patients with Streptococcus bovis infective endocarditis. Finally, the implications and therapeutic strategies in these patients are discussed.
