Purpose: to evaluate the effects of tibolone on climacteric symptoms and clinical and metabolic variables. Methods: thirty-four postmenopausal women were treated orally with 2.5 mg tibolone daily for 48 weeks and evaluated as to climacteric complaints, clinical aspects such as weight and blood pressure and lipid profile (total cholesterol, HDL-c, LDL-c, VLDL-c and triglycerides). Results: a significant improvement of climacteric complaints was demonstrated by a significant decrease in the Kupperman index (p<0.001) and the mean number of hot flushes (p<0.001) from the first month of treatment onwards. There was a significant decrease in total cholesterol, triglycerides and VLDL-c (p<0.001). The LDL-c levels presented a slight decrease (not significant). The HDL-c levels showed a significant decrease at week 24. However these levels returned to baseline levels at week 48. With regard to the vital signs no change in body weight and blood pressure was measured. The side effects were mild and temporary, vaginal bleeding, nausea and edema being the most common. Conclusion: tibolone may be considered a safe and efficient option to treat climacteric symptoms in postmenopausal women without significant impact on lipid profile.

Purpose: to evaluate the morphologic and morphometric alterations produced by tamoxifen and conjugated estrogens in the mammary epithelium of rats in persistent estrus. Methods: thirty-three adult female rats in persistent estrus induced with 1.25 mg testosterone propionate were divided at random into three groups: GI -- which received only water, control group (n = 12); GII -- treated with 500 mug tamoxifen daily (n = 10); GIII -- treated with 30 mug conjugated estrogens per day (n = 11). The first inguinal-abdominal pair of mammary glands of the animals was extirpated and processed for morphologic and morphometric study. Data were analyzed statistically by the Kruskal-Wallis rank analysis of variance (p < 0.05). Results: the morphologic study revealed signs of epithelial atrophy and the morphometric study showed a statistically significant reduction in the mean number of ducts and alveoli in groups II (10.1 and 1.9, respectively) and III (11.1 and 3.5, respectively) compared to group I (25.0 and 6.6, respectively). There was no significant difference between groups II and III. Conclusions: the results of this study indicate that tamoxifen as well as conjugated estrogens at the tested doses produced mammary epithelial atrophy in rats in persistent estrus.

Purpose: to determine magnesium sulfate effectiveness to prevent eclamptic seizures in pregnant women diagnosed with preeclampsia. Methods: a case-control study involving 489 pregnant patients admitted to the Hospital de Clínicas de Porto Alegre (HCPA) with the diagnosis of hypertension between January 1990 and January 1997. The patients were divided into two groups: those who received magnesium sulfate (Group I) and those who did not (Group II). All patients were treated according to the hospital's standard protocol for the treatment of hypertensive pregnant women. The following variables were assessed: maternal age, race, number of seizures, number of seizures in patients receiving magnesium sulfate, period of magnesium sulfate administration, before and after delivery, maternal mortality, need of ICU care, need of mechanical ventilation and length of hospital stay after delivery. Data were assessed with Epi-Info 6.0 statistical package, using multivariate analysis. The main outcome measure was magnesium sulfate use. Results: no differences were found between the two groups in terms of maternal age, race or gestational age. Women who received magnesium sulfate had a higher mean systolic and diastolic blood pressure. Women in the intervention group had a longer hospital stay and a greater need of ICU care. Need of mechanical ventilation and maternal mortality were similar in the two groups. Twenty-two out of 353 women had one or more seizures before admission to the hospital. Six women (27.3%) had one or two additional seizures after magnesium sulfate administration. No subjects had three or more seizures after receiving magnesium sulfate. Conclusion: the results show that eclamptic seizures can be prevented by routine prophylactic magnesium sulfate administration.

Purpose: the aim of the present work was to study the chronic action of the antiemetic domperidone on the pregnancy of albino rats. Methods: fifty albino, pregnant Wistar rats were randomly allocated to five groups: GI (control I) = intact rats; GII (control II) = rats receiving the drug vehicle (distilled water) by gavage at the same schedule of the experimental groups; rats in groups GIII, GIV and GV were treated with domperidone by gavage, 2, 6 and 12 mg/kg per day, respectively, divided into 4 daily doses, always in 1 ml of distilled water, from time zero up to the 20th day of pregnancy. The evolution of body weight gain was followed throughout and the animals were sacrificed at term (20th day) by deep ether anesthesia. Number of fetuses, placenta and implantation sites, placenta and fetus weight, fetal malformations and maternal and fetal mortality were evaluated. Results: we observed only intrauterine fetal mortality with 14, 26 and 32 in 74, 60 and 57 newborns of the groups III, IV and V, respectively. Conclusion: though the results of animal experimentation cannot directly be transposed to human conditions, this paper calls attention to the need for a safe judgement when prescribing domperidone to a first-trimester pregnant patient in order to reduce her emetic crises.

Purpose: to evaluate the prevalence of anticardiolipin antibody in women with stillbirth. Patients and Methods: this was a cross-sectional study performed from May 1998 to September 1999 at the Maternity of the University of Campinas and at the Hospital and Maternity Leonor Mendes de Barros, in Brazil, which evaluated 109 pregnant women hospitalized with the diagnosis of intrauterine fetal death and gestational age of 20 or more weeks. These women underwent some laboratory examinations to identify the cause of fetal death, including anticardiolipin antibody evaluation performed through the determination of IgG and IgM serum levels. IgG and IgM results are expressed as GPL and MPL units, respectively, and, in both cases, results above 10 units are considered positive. The statistical procedures used were the mean and standard deviation estimates, Student's t test, Fisher test and chi². Results: the prevalence of anticardiolipin positivity was 18.3%. The women were predominantly young, with a mean age around 27 years. The main identified causes of fetal death were: hypertension (26.1%), hemorrhage during the third trimester (9.9%) and fetal malformation (8.1%). One third of the cases had no identified causes of fetal death. However, considering the 20 positive cases for anticardiolipin antibody, the proportion of unidentified causes decreased to 29%. Conclusions: it is important to investigate the presence of anticardiolipin antibodies among women with intrauterine fetal death with the purpose of clarifying the causes of stillbirth. If the diagnosis of antiphospholipid syndrome is confirmed, it is necessary to counsel and treat these women regarding future pregnancies.

SUMMARY Purpose: to study the usefulness of minilaparoscopy in diagnosing the cause of pelvic pain. Methods: women with pelvic pain were prospectively analyzed and underwent an office video-microlaparoscopy. We analyzed the data regarding procedure time, stay in the recovery room, acceptance of anesthesia, and morbidity. Results: the average procedure time of the office video-microlaparoscopy was 19 min, the average stay for recovery was 43 min, and the technical quality of the image was excellent or good in 100% of the selected patients. The following laparoscopic findings were reported: 34.4% endometriosis, 28.1% pelvic adhesion, 12.5% pelvic varices, and 25% normal. Based on Bordhal et al.'s¹ criteria, a low frequency of pain manifestation during local anesthesia (12.5%) and discomfort on pneumoperitoneum (46.9%) were noticed. It could also be observed that, according to Milki and Tazuke's² criteria, the tolerance to the method was excellent and good (96.9%). Twenty-four hours after the procedure the morbidity rate was in accordance with Chung et al.'s³ criteria, showing a high frequency of pain at the incision area (59.4%) and sleepiness (43.8%). Only 3.1% reported they felt pain during the procedure, which shows the acceptance of the method by the patients. Conclusions: the acceptance of anesthesia and of the surgical procedure and the low morbidity allow the use of minilaparoscopy as a very important method in investigating patients with pelvic pain.

Purpose: to evaluate the lipid profile (cholesterol, triglycerides, HDL and LDL) of women with polycystic ovary syndrome (PCO) and compare it to that of women with ovulatory menstrual cycles. Methods: the patients were divided into two groups, obese and nonobese, based on body mass index, so that it would be possible to determine the joint effect of PCO and obesity on the lipid metabolism of the studied women. We studied 117 women divided into 4 groups: group I (PCO--obese), n = 33; group II (PCO--nonobese), n = 27; group III (control--obese), n = 28; group IV (control--nonobese), n = 29. Results: cholesterol levels were elevated (179 mg/dl) in obese patients with ovulatory cycles (group III) compared to group I (147 mg/dl) and group II (149 mg/dl), as also were triglyceride levels (117 mg/dl) compared to group IV (77 mg/dl) and LDL levels (117 mg/dl) compared to group I (82 mg/dl). Conclusion: these data suggest that alterations in lipid profile are related to obesity only.

Purpose: to assess the esthetic results and personal satisfaction of patients submitted to conservative surgery for cancer of the breast. The study was conducted on 44 patients with breast cancer diagnosed at the mastology outpatient clinic of HCFMRP-USP from January 1990 to December 1994, who fulfilled inclusion criteria according to a previously established protocol. The study consisted of analysis of the esthetic results after conservative treatment of breast cancer and analysis of the degree of patient satisfaction, with a comparison of the morphometry of the treated breast to that of the normal breast. The results were obtained on the basis of five previously established parameters using the esthetic evaluation score proposed by Westreich¹. Methods: of the 44 patients studied, 10 had been submitted to neoadjuvant chemotherapy (CT) because they presented locally advanced tumors, and 2 because of an unfavorable tumor/breast ratio for conservative treatment. Mean follow-up time was 65 months. All 27 patients followed-up at the outpatient clinic received a convocation letter. An evaluation questionnaire was applied to the 20 patients who came to the clinic, followed by breast measurement. Fifteen of these patients had been submitted to surgery with separate incisions and 5 to surgery with a single incision. Results: according to morphometry, the results were classified as excellent in 17 cases (85%), as good in two (10%), and as poor in only one case (5%), an evaluation comparable to the subjective evaluation made by the patients themselves. Considered separately, both measurement "A" (distance from the manubrium of the sternum to the nipple) and measurement "B" (distance from the cranial articulation of the xyphoid appendix to the nipple) showed a greater discriminative power than the measurements as a whole, since with these measurements the cases classified as poor by the patients would have also been classified as poor according to these same criteria separately (A and/or B). Conclusion: there was a significant difference in esthetic results between surgical treatment with a single incision or separate incisions, with the separate incision providing better results. There was high agreement between the classification made by the patients and the morphometric results obtained by us.
