PURPOSE: to evaluate the nutritional condition of pregnant adolescents using the pregestational body mass index (BMI) and the BMI at the end of pregnancy and to establish a possible association with the type of delivery and weight of the newborn child. METHODS: in a descriptive retrospective observational study 558 pregnant teenagers as well as their newborns were evaluated in the Obstetrics outpatient clinic of the Universidade Federal de São Paulo, Brazil (UNIFESP-EPM), from January 1998 to December 2000. The sample consisted of pregnant girls who were between 10 and 19 years old at the time of the first prenatal examination, excluding the teenagers who had preexistent disease and those with incomplete data in their records. Thus, the sample consisted of 300 pregnant teenagers. Qualitative variables are presented as absolute and relative frequency and quantitative variables as mean, standard deviation and range. The correlation between maternal variables (pre-pregnancy BMI and final BMI) and parameters of the newborn (type of delivery and weight) was determined by the c² test and the differences were identified by partitioning of the c² values, with the level of significance set at p < 0.05 (a = 0.05). RESULTS: nutritional deviation was detected in 34.7% of the girls, at the beginning of pregnancy. Of these adolescents, 27.7% presented malnutrition, 4% were overweight and 3% were obese. By the end of the gestational period, BMI of 54.3% of them was normal, 1.3% correponded to malnutrition, 27% to overweight and 17.3% to obesity. The mother's nutritional condition (malnutrition, normal, overweight and obesity) did not affect the method of delivery, either vaginal (80.3%) or cesarean section (19.7%). The patients who reached end of pregnancy with BMI corresponding to malnutrition had 75% of neonates under 2.500 g. CONCLUSIONS: the mother's nutritional status was not related to the type of delivery. BMI corresponding to malnutrition at the end of pregnancy was significantly related to more cases of newborn babies under 2.500 g.

PURPOSE: to evaluate maternal age of 40 and older as an independent risk factor for pregnancy-induced hypertension (PIH). METHOD: we conducted a retrospective cohort study involving analysis of medical records of 2047 women in labor, divided into groups of 298 aged 40 and older and 1749 aged under 40. A multiple logistic regression was done to evaluate the association of maternal age with the occurrence of PIH adjusted by parity, chronic arterial hypertension, diabetes and twin pregnancy. RESULTS: the incidence of PIH in patients aged 40 and over was 22.1% (66/298), higher than in patients aged under 40 (16%, 286/1463). PIH was diagnosed in 27.2% of primiparous (174/640), 47.6% of chronic hypertensive (30/66) and 27.1% of diabetic patients (13/48). Advancing maternal age, primiparity and chronic arterial hypertension were associated with the occurrence of PIH in univariate analysis (OR = 1.46, 2.58 and 4.69, respectively). There was no significant association with diabetes. After the adjustment we observed an increase in the strength of the association between maternal age and PIH (adjusted OR = 1.69), as well as parity and chronic arterial hypertension. CONCLUSION: maternal age of 40 and older was a risk factor for the occurrence of PIH independent of parity, chronic arterial hypertension and diabetes.

PURPOSE: to evaluate the association between the variability of amniotic fluid index (AFI) values with gestational age and some sociodemographic and obstetric variables among low-risk pregnant women. METHOD: a comparative study was carried out including 2868 low-risk pregnant women who had routine obstetric ultrasound examination, including fetal biometry and the measurement of AFI, from 20 to 42 weeks of gestation. The data were analyzed using Student's t test, analysis of variance of mean AFI values along gestational ages, according to other control variables, and also by multiple linear regression analysis. RESULTS: there was no significant variation of mean AFI values during the time of pregnancy neither when separately evaluating its association with maternal age, color, education, smoking habit, parity, and the presence of previous cesarean section scars, nor when the evaluation was performed through multivariate analysis. In this situation only the increase in gestational age showed to be associated with the decrease of AFI. Generally speaking, the mean AFI values fluctuated between 140 and 180 mm between the 20th and the 36th week, then showing values below 140 mm in a progressive decrease after this limit of gestational age. CONCLUSIONS: AFI values do not show a significant variation during pregnancy regarding the studied sociodemographic and obstetric variables.

PURPOSE: to study the effects of physiotherapeutic techniques applied by the Multidisciplinary Program of Preparation for the Childbirth and Maternity on musculoskeletal discomforts during pregnancy. METHODS: prospective cohort study, with 71 low-risk nulliparous women, distributed according to participation (study: n=38) or not (control; n=33). The Multidisciplinary Program of Preparation for Childbirh and Maternity had 10 meetings (18th to 38th week), with educational, physiotherapeutic, and interaction activities. Occurrence, characteristics, and evolution of musculoskeletal discomforts were compared by means of a specific questionnaire, both at the beginning and at the end of the program. The average of results of the initial assessment was compared through analysis of variance (ANOVA) followed by the F test. For the study between proportions in the beginning and at the end of the program the c² was used. The statistical significance was determined at 5% of limit (p<0.05). RESULTS: at the beginning of the program, 63.6% of the pregnant women of the control group and 84.2% of the study group reported musculoskeletal symptoms (p=0.05), characterized by back and posterior pelvic pain. In the control group, light intensity (18.2%) and serious intensity pain (18.4) were predominant, while in the study group, the serious was 36.8%, and the isolated or associated was 31.6%. At the end, the control group showed symptoms of serious intensity (60.6%), with daily frequency (42.4%) and length of more than 3 h (69.7%; p<0.05). The study group reported light intensity (57.9%) and bimonthly frequency (50.0%) with a maximum length of one hour (55.3%) (p<0.05). Symptom evolution was also differentiated and there were worsening in 63.6% of pregnant women of the control group and improvement in 65.8% of participants of the program (p<0.05). CONCLUSIONS: the physiotherapeutic techniques of the Multidisciplinary Program of Preparation for Childbirth and Maternity were related to a decrease in intensity, frequency and length and to a better evolution of musculoskeletal discomforts during pregnancy.

PURPOSE: to assess the simultaneous approach of radioguided occult lesion localization and sentinel lymph node biopsy in women with breast cancer. METHOD: forty-five patients with nonpalpable breast cancer were enrolled in a prospective study. The employed radiocolloid was 99mTc-labelled dextran. The injection was performed peritumorally under sonographic or stereotactic guidance using a 18 gauge needle. Lymphoscintigraph images for the visualization of both the site of injection and sentinel lymph node were obtained in a conventional gamma-camera, with the ipsilateral arm positioned in a 90º angle. Excision biopsy of the tumor and sentinel lymph node were performed with a gamma-detecting probe. RESULTS: the procedure was always successful in permitting the localization of occult breast lesions. It was necessary to enlarge surgical margins in five cases. Concerning the sentinel lymph node we achieved localization in 93% of the cases. No complications were observed. CONCLUSION: the results seems to demonstrate that a combined radioguided occult lesion localization and sentinel lymph node biopsy using the same radiopharmaceutical represents a useful and practicable strategy in the management of early breast cancer.

PURPOSE: to present the most frequent gynecologic results in a cohort of 300 outpatient HIV-infected women. METHODS: this is a prospective and descriptive study of HIV-infected women that have been followed up at the gynecological clinic from November 1996 to December 2002. These patients were subjected to a specific protocol which included an interview, a gynecological evaluation and a collecting cervical sample for Pap smear, research of HPV (PCR) and colposcopy. Cervical biopsy was performed when necessary. Data were stored and analyzed by Epi-Info, version 6.0. RESULTS: the mean age was 34.5 years. The small number of sexual partners, average of three partners, and the predominance of heterosexual contagion should be mentioned: 271 (90.6%) patients were contaminated through sexual contact with their partners. There was a high prevalence of cervical intraepithelial neoplasia (CIN) representing 21.7% of the total group. Of 109 patients subjected to PCR, 89 (81.7%) were found to have some HPV genotype. An inflammatory smear was present in 69% of the patients. CONCLUSIONS: there is a high frequency of CIN and genital infectious diseases among HIV-infected women, mainly HPV.

PURPOSE: to compare the results of hysterosonography with those of hysteroscopy and the histopathologic study in postmenopausal women. METHODS: hysterosonography, hysteroscopy and endometrial biopsy were performed in 59 women who had an endometrial echo over 4 mm, age above 40 years and amenorrhea over one year, and whose follicle-stimulating hormone levels were over 35 mIU/mL. Patients using hormones were excluded, as well those in whom it was impossible to perform histerosonography, histeroscopy or endometrial biopsy. The statistical analysis was performed using the nonparametric "G"-Cochran and McNemar tests. In addition, sensitivity and specificity, as well as positive and negative predictive values were determined. The value of 0.05 or 5% for rejection level of the null hypothesis was applied. RESULTS: the agreement rates of hysterosonographic results compared to hysteroscopy and histopatology were 94.8 ande 77.6%, respectively. Sensitivity and specificity of hysterosonographic evaluation of the abnormal endometrial cavity were 98 and 75%, respectively, when compared to hysteroscopy. In addittion, positive and negative predictive values of hysterosonography were 96 and 86%, respectively. When the histopathologic study was used as the gold standard, sensitivity and specificity were 98 and 33%, with positive predictive value of 76% and negative predictive value of 86%, for the detection of the endometrial cavitary changes. One great concern were the histopathologic results of two patients with uterine synechia who showed endometrial hyperplasia. Also, one patient was diagnosed as normal using histerosonography and the histopatological result showed simple hyperplasia. CONCLUSIONS: our data suggest that hysterosonography presented good sensitivity as compared with hysteroscopy. However, uterine synechia is the great limitation of this method as compared with histopathology.
