PURPOSE: to compare pregnancy rates and mean endometrial thickness obtained with three protocols for induction of ovulation in cycles of intrauterine insemination (IUI). METHODS: one hundred and ten IUI cycles were retrospectively evaluated in the study, divided into three groups, according to the used ovulation induction protocols: 100 mg clomiphene citrate (CC) on days 3 to 7 of the cycle (CC group, n=24), 100 mg/day CC on days 3 to 7 of the cycle + 75 IU/day of human menopausal gonadotrophin (hMG) on days 3, 5 and 7 of the cycle (CC+hMG group, n=29), and 75 IU/day of hMG on days 3 to 8 of the cycle (hMG group, n=57). Statistical analysis was performed using Student's t test to compare the means and the c² test to compare the rates. Results were considered statistically significant at p<0.05. RESULTS: the patients' average age at the onset of the first cycle was 2340 years (mean age, 33.3 years). There were no statistically significant differences between groups. The mean endometrial thickness on the day of the human chorionic gonadotrophin (hCG) administration was significantly higher in the hMG group (10.2±0.2 mm), as compared with the CC and CC+hMG group (7.9±0.4 and 8.7±0.2 mm, respectively, p<0.001). The overall clinical pregnancy rate was 18.2%, and there were no statistically significant differences between the groups (CC group=12.5%; CC+hMG group=24.1% and hMG group=19.3%). CONCLUSION: the results indicate higher mean endometrial thickness in the hMG group as compared with the CC group and the CC+hMG group. There were no significant differences between clinical pregnancy rates obtained with each protocol (CC, CC+hMG and hMG).

PURPOSE: to perform a critical evaluation of the histopathological diagnosis of ductal carcinoma in situ (DCIS) of the breast, through the analysis of interobserver variation related to diagnosis, architectural pattern, nuclear grade, and histological grade. METHODS: eighty-five cases with an initial diagnosis of DCIS were reviewed by the same pathologist, specialist in breast pathology, who selected 15 cases for interobserver analysis. The analysis was carried out by five pathologists and an international expert in breast pathology, who received the same slides and a protocol for classifying the lesions as atypical ductal hyperplasia (ADH), DCIS, or ductal carcinoma in situ with microinvasion (DCIS-MIC). If the diagnosis was DCIS, the pathologists should classify it according to the dominant architectural pattern, nuclear grade, and histological grade. The results were analyzed using percent concordance and the kappa test. RESULTS: there was a great interobserver diagnostic variation. In one case we had all diagnoses, from ADH, DCIS to DCIS-MIC. The kappa test for the comparison among the five observers' and the expert's diagnoses showed minimum interobservers' concordance (<0.40). Regarding DCIS classification related to the dominant architectural pattern and the histological grade, the kappa test values were considered poor among the pathologists. The best results were obtained for the nuclear grading, with a kappa index up to 0.80, considered as good concordance. CONCLUSION: the low index of interobserver concordance in diagnosis and classification of DCIS of the breast indicates the difficulty in using the most common diagnostic criteria of the literature and the need for specific training of non-specialist pathologists in breast pathology for the diagnosis of these lesions.

PURPOSE: to evaluate and compare results of female pelvic floor surface electromyography in different positions: lying, sitting and standing. METHODS: twenty-six women with the diagnosis of stress urinary incontinence treated with a protocol of exercises to strengthen the pelvic floor muscle were evaluated. Pelvic floor surface electromyography was performed with an intravaginal sensor connected to Myotrac 3G TM equipment, as follows: initial rest of 60 s, five phasic contractions, one 10-s tonic contraction and one 20-s tonic contraction. The amplitudes were obtained from the difference between the final contraction amplitude and the amplitude at rest (in µV). Wilcoxon test was applied for nonparametric data (p value <0.05). RESULTS: the amplitudes of contractions were higher in the lying position, decreasing in the sitting and standing positions. In the lying position, the median values of phasic and tonic contractions were 23.5 (5-73), 18.0 (3-58) and 17.0 (2-48), respectively. In the sitting position, they were 20.0 (2-69), 16.0 (0-58) and 15.5 (1-48). In the standing position they were 16.5 (3-67), 12.5 (2-54) and 13.5 (2-41). All amplitude values were significantly lower in the standing position compared to the lying position (p<0.001, p<0.001 and p=0.003). Similar results were also found in comparison to the sitting position. However, there was no significant difference between the lying and the sitting positions. CONCLUSION: all female pelvic floor contraction amplitudes were lower in the standing position, suggesting that the muscle strength should be intensified in that position.

PURPOSE: to compare the effectiveness and safety of sublingual misoprostol (25 µg) versus vaginal misoprostol (25 µg) (Prostokos®) for labor induction with gestational age > 37 weeks and unripe cervices. METHODS: a randomized controlled clinical trial was performed at the Maternidade Monteiro de Morais (CISAM-UPE), in Recife - PE, Brazil, from October 2003 to February 2004. One hundred and twenty-three women with gestational age > 37 weeks, Bishop score <8, not in labor and with medical indication for interruption of pregnancy were included in this study. The women received randomly 25 µg sublingual misoprostol or 25 µg vaginal misoprostol every 6 h, not exceeding eight doses. In order to evaluate the differences between the groups, means, standard deviations, Student's t-test, c² trend and Mann-Whitney test were used. The statistical significance was considered to be 5%. RESULTS: there were no significant differences between the number of women with vaginal delivery in the sublingual group as compared with the vaginal group (65.5 vs 75.8%, p<0.22), or in the interval of time between the induction onset and delivery (24 h and 42 min vs 20 h and 37 min respectively, p=0.11). The two groups, sublingual and vaginal, also did not differ as to the hyperstimulation syndrome (1.7 vs 3.2%, p=0.95), meconium incidence (5.2 vs 4.8%, p=0.74), Apgar score <7 at 5 min (3.4 vs 4.8%, p=0.98) and other adverse effects. CONCLUSION: twenty-five micrograms of sublingual misoprostol every six h presented the same effectiveness and safety as an equal vaginally administered dose of this substance. Sublingual misoprostol seems to be acceptable and is another option to be considered for labor induction.

PURPOSE: to evaluate the prevalence of HIV infection in parturient women from maternity hospitals linked to the Public Health Service in Sergipe state (Brazil) using the rapid test, and to evaluate this strategy to introduce the protocol for adequate management of HIV patients. METHODS: cross-sectional study which included the training of all health personnel and enrollment of every parturient woman admitted to maternity hospitals linked to the Public Health Service of Sergipe in the Northeast of Brazil. They received instructions about HIV perinatal transmission, were asked to undertake the rapid test, independently of their knowledge about their HIV serologic status, and signed the term of free consent. Additional information about antenatal care and obstetric history was obtained. The test used was the DetermineTM - Abbott Laboratories, and we used the Health Ministry protocol for HIV infeccion prophylaxis. A database was created at Epi-Info 2002, and the prevalence was calculated in relation to all tests performed from January 2003 to March 2004. RESULTS: after 9215 performed tests, 39 HIV-seropositive patients (0.42%) were detected. Twenty-three of them (59%) had no previous knowledge about their seropositivity. Two patients that already knew their positive sorology status did not refer this condition to the health persomel. The Health Ministry protocol was used for all positive cases. Antenatal care attendance was high (89%) but only 32.5% of the patients had already been submitted to an HIV serologic test during pregnancy. CONCLUSIONS: HIV prevalence in pregnant women (0.42%) in Sergipe was similar to the average rate in Brazil. A large number of seropositive pregnant women did not know their serologic status at the moment of delivery. This indicates bad antenatal care performance and the necessity to keep using HIV rapid test at the moment of labor and delivery in order to reduce vertical transmission.

PURPOSE: to investigate the normal peak expiratory flow values in healthy pregnant women employing a portable expiratory apparatus (Mini-Wright Peak Flow Meter), and to relate the obtained measurements to each patient's height, body mass index (BMI) and age, along gestation. METHODS: a longitudinal prospective study including 26 pregnant women followed up from the first trimester to the 36th week of gestation and examined every four weeks. On the occasion of seven visits, the pregnant women performed forced exhaling into a portable expiratory apparatus three times, with the highest value being considered the peak expiratory flow. All measurements were made under the same investigator's supervision in order to reduce the margin of error. Pearson coefficient was used to calculate the correlation between flow and BMI, between flow and patient's height, and between flow and patient's age. RESULTS: the variation in flow values during pregnancy can be determined by flow = 328.32 -0.07 x week, with a Pearson coefficient equal to zero. To determine whether there was a difference in the correlation coefficients between BMI and flow, we compared the lowest coefficient (0.47 for week 30, flow = 123.49 + 7.64 x BMI) with the highest coefficient (0.59 for week 34, flow = 87.77 + 9.05 x BMI) of each studied time interval and obtained a value of 0.22, indicating a good correlation between the flow and BMI variables. There was a positive correlation between height and flow (Pearson = 0.61), with flow = -477.47 + 497.38 x height. The correlation coefficient between flow and age was 0.24, with the equation obtained in this case being non-linear. CONCLUSIONS: peak expiratory flow values did not change along gestation. Higher flows were observed in taller women. Pregnant women with a higher BMI before gestation presented higher flows. There was no correlation between flow and maternal age.
