Juxtaglomerular cell tumor as a rare cause of hypertension in adults

The juxtaglomerular cell tumor is a cause of secondary hypertension in adults. A 35-year-old female patient suffering from hypertension and low serum potassium had a 3 x 3 cm solid mass at the lower pole of left kidney diagnosed by abdominal sonography. Partial nephrectomy was performed and the postoperatory was uneventful. Normalization of blood pressure was observed within the first month.

[Comparative study of the coronary circulation pattern of anatomic specimens and surgical patients]. / Estudo comparativo do padrão de circulação coronariana entre peças anatômicas e pacientes cirúrgicos.

The recent improvement in the cardiac surgery requires a continuous study of the great anatomy of the heart. In this paper, we compare the anatomic pattern of the coronary artery between normal individuals and individuals with sintomatic ischemic disease of the heart. The anatomic pattern of circulation was carried out in two different groups: group I formed by 119 anatomical specimens taken from individuals whose cause of death was non-cardiac and group II formed by 150 live individuals with sintomatic coronary disease, on pre-operative management. In the former was performed epicardiectomy and in the latter, radiologic study. In group I was found 68% of right predominance, 13% of left predominance and 19% of balanced type of circulation. In group II was found 59%, 17% and 24%, respectively. When considering the number of branches that trespass the crux cordis in group I, there was 48% with only one branch, 28% with two, 17% with three, 4% with four and 3% with five branches. Performing the same study for group II, we found 47%, 29%, 14.6%, 3.4% and 6% respectively. Both groups were compared by Chi-square test and by Fisher's Exact test and no considerable difference was pointed out.
