The present study describes 13 cases of appendicitis in the gravidic-puerperal cycle, at the Maternidade Escola Januário Cicco, from Jan/89 to Dec/96. The cases were assisted by a team of obstetricians and surgeons. Eleven patients were pregnant (4 in the 1st trimester, 6 in the 2nd and 1 in the 3rd) and 2 were in the puerperal period. The incidence was 1/3.422; the age ranged from 18 to 30 years and the majority was nulliparous. The most frequent symptom was abdominal pain (intense or moderate). The appendix was perforated in 6 cases, 2 of them with abdominal wall abscess and 1 patient had an abortion. Pregnancy presented no complications in 9 cases, and delivery occurred at term. The authors observed that appendix perforations occurred more frequently in cases whose symptoms had begun earlier. The authors found that the earlier the diagnosis, the better the prognosis.

Purpose: to develop an experimental model in rats to study the interaction between hypertension and pregnancy. Methods: the present experiment was divided into 5 periods: adaptation (2 weeks), surgical procedures (1 week), hypertension development (6 weeks), mating and blood pressure stabilization (6 weeks), and gestational period (3 weeks). A total of 82 animals in reproductive age, weighing from 180 to 240 g, were used. They were randomly assigned to the 4 different groups (control, handled, nephrectomy and hypertension) and renal hypertension was produced by a controlled constriction of the main left renal artery, according to the technique described by Goldblatt, and contralateral nephrectomy (Goldblatt I - one kidney, one clip hypertension). They were studied at 15 precise moments. Afterwards, periodic blood pressure determinations were made by the tail plethysmographic method. Results: pregnancy caused a fall in blood pressure levels in the rat. Conclusion: the experimental model was adequate for the purposes of the study, since it proved to be efficient in producing hypertension.
