Purpose: to study the changes in amniotic fluid index (AFI) measured by ultrasonography, mean arterial pressure (MAP) and pulse rate in normal pregnant women submitted to subtotal body immersion in water for different periods of time, and to standardize the technique. Methods: AFI values were studied as recommended by Phelan et al.¹ in a group of 52 pregnant women with gestational age of 28 weeks or more considered to be clinically normal, before and after exposure to subtotal immersion in water heated to 32 to 34ºC for 30, 45 and 60 min. The patients were seen at the Ultrasonography and Medical Updating School of Ribeirão Preto and in the Department of Gynecology and Obstetrics of the Faculty of Medicine of Ribeirão Preto, University of São Paulo. Results: before and after immersion, the average of MAP was 87.8 and 87.1 in the group of 30 min, 76.7 and 66.6 in the group of 45 min and 77.4 and 60.7 in the group of 60 min, with statistical significance. Before and after immersion, the means of pulse rates were 74.9 and 78.7 in the group of 30 min, 83.6 and 85.2 in the group of 45 min and 84.9 and 90.6 in the group of 60 min, with statistical significance. The mean of AFI also showed statistical significance. When submitted to 30-min immersion the means of AFI were 11.7 cm before and 16.8 cm after. In the group of 45 min, the averages were 9.7 cm before and 13.8 cm after immersion. In the group of 60 min, the averages were 9.5 cm before and 13.6 cm after immersion. The time of immersion of 30-min was as effective and ample as 45 or 60 min. Conclusions: subtotal immersion in water is a safe and practical procedure that can mobilize fluids during pregnancy, increasing amniotic fluid volume.

Purpose: to evaluate the results of a rapid diagnostic test for HIV-1 infection made available by the Health Ministry for the identification of pregnant women contaminated by this virus. Methods: we evaluated prospectively 443 pregnant women with no prenatal serologic anti-HIV test seen at the Department of Gynecology and Obstetrics of the Faculty of Medicine of Ribeirão Preto, University of São Paulo, from February to June, 2000. Samples from these patients were submitted to the rapid immunochromatographic test, which was compared with ELISA and submitted to a confirmatory agglutination test. Results: among the 443 pregnant women submitted to the rapid test (20.1% of the deliveries performed during the study period), 16 showed positive results (3.6%). No sample with a negative result by the rapid test was positive by ELISA. However, of the 16 samples that were positive by the rapid test, two were negative by the confirmatory tests. Thus, the rapid test showed 100.0% sensitivity, 99.5% specificity, 87.5% positive predictive value, and 100.0% negative predictive value. Conclusions: the results obtained by evaluation of the test for a rapid diagnosis of HIV-1 infection in pregnant women revealed sensitivity, specificity and predictive values that qualify it as an extremely important resource for the indication of measures that will reduce perinatal transmission of this virus.

Purpose: to examine the effects of tramadol hydrochloride on rat pregnancy. Methods: five groups of 10 pregnant albino rats each were treated from the 1st up to the 20th day of pregnancy as follows: GI = intact controls; GII = controls which received 0.5 ml of distilled water (drug vehicle) once a day by gavage; GIII, GIV and GV = groups treated respectively with 6.7, 20.1 or 45.6 mg/kg of tramadol hydrochloride once a day by gavage in a final volume of 0.5 mL. Body weight gain was monitored by weighing at the beginning and on the 7th, 14th and 20th day of pregnancy. At term the animals were killed under deep ether anesthesia and the following parameters were evaluated: number of implantations, of resorptions, of viable fetuses and of placentae; presence of major malformations; maternal and fetal mortality and weights of fetuses and placentae. Results: tramadol significantly affected maternal body weight gain, this effect being more apparent in groups IV and V (mean reductions of weight gain of 41 and 56%, respectively). In group III the weight gain was affected more at days 7 and 14 (33% mean gain reductions) than at day 20 (19%). Drug treatment affected significantly and in a dose-dependent fashion the following parameters: individual weight of fetuses (GV = -39.2%), offspring weight (GIV = -51.7%; GV = -44.2%), number of placentae (GIV = -28.4%; GV = -11.6%), individual weight of placentae (GV = -10%) and the total weight of placentae (GIV = -28.4%; GV = -16.8%). Though among the treated animals there was an increase in resorptions and deaths at birth, these events were not significantly different from those found in controls. Conclusions: Tramadol showed definite deleterious effects on albino rat pregnancy, and these effects were exerted not only on the maternal but also the on fetal organisms. Overall, the effects were more pronounced at the 14th than at the 20th day of pregnancy, thus suggesting that the organogenic phase of the fetus is more susceptible than its initial (embryogenic) or final (term) phases. The results call attention to the care which is to be taken when the use of this opioid is considered during pregnancy.

Endometrial metaplastic ossification is a rare condition and can be partially explained by a neoformation in the endometrium, with calcium deposition. However, a common situation is the previous history of abortion with persistence of ossicles in the uterine cavity. The endometrial ossification was reported in a 31-year-old woman, without previous pregnancy or history of abortion. This patient presented dysmenorrhea and infertility. Pelvic ultrasonography showed a hyperechoic area in the uterine fundus. Histeroscopy was performed and an image suggestive of bone was seen. This tissue was removed by histeroscopy and the histopathological analysis confirmed endometrial ossification.
