PURPOSE: to describe the frequency of clinical and laboratorial findings in pregnant women with malaria. METHODS: a descriptive study was performed including 445 pregnant women with a positive diagnosis of malaria of the Maternity and women's Clinic Bárbara Heliodora (Rio Branco, Acre State), from January 1996 to December 2001. These cases were reviewed and the pregant women with malaria were selected. RESULTS: a total of 33,420 patients were hospitalized in that period. Of these, 445 pregnant women (1.4%) were included. Among these, the frequency of the infection with Plasmodium vivax was 52.8% (n=235), with P. falciparum, 43.8% (n=195), and 3.4% (n=15) with both plasmodia. The most frequent clinical and laboratorial alterations (p<0.05) were observed in the patients with P. falciparum: pale mucosa, jaundice hemoglobin and hematocrit decrease, hypoglycemia and increase in serum aminotransferase, urea, creatinine and in bilirubin levels. Only one patient (1/445), a pregnant woman infected with P. falciparum died. Abortions, premature birth and low birth weight were detected in 1.3, 1.1 and 1.1% of the cases, respectively. CONCLUSIONS: these findings reflect the repercussion of malaria during pregnancy, and justify the existence of qualified medical care in obstetric units for diagnosis and treatment of these cases, especially in the Amazon region.

PURPOSE: the morbidity in HIV-positive patients due to puerperal fever was studied and correlated to the method and duration of labor, the duration of premature rupture of the membranes, CD4+ cell count and the viral load (VL) at peridelivery. METHODS: a total of 207 HIV-positive women with prenatal examinations and deliveries between May 1997 and December 2001 were enrolled. Of these, 32 had natural childbirth and 175 had a cesarean section. Of the total of enrolled patients, 62.8% were submitted to elective cesarean section. The average age of the group was 27.4 years, and 25.6% were nulliparous and 26% were primiparous. At the moment of the delivery the average gestational age was 37.8 weeks. At the end of pregnancy the average of the CD4+ cell count was approximately 481 cells/mm³ and the viral load 49,100 copies/mL. RESULTS: puerperal morbidity occurred in 34 patients, with 33 after cesarean section and one after natural childbirth. The most usual intercurrent post-cesarean infection was that of the surgical wound (13% of the infection cases). Analyzed factors, such as delivery duration, duration of rupture of the membranes, number of CD4+ cells or the viral load at peridelivery, did not interfere in puerperal morbidity. CONCLUSIONS: puerperal morbidity was 16.8% and occurred more frequently after cesarean sections (18.9%) than after vaginal deliveries (3.1%). The other factors did not present a significant effect on puerperal morbidity.

PURPOSE: to show longitudinally the profiles and parameters of pressure rhythm and heart rate in normotensive pregnant women during the three trimesters of pregnancy. PATIENTS AND METHODS: the longitudinal and random study involved 23 normotensive pregnant women, mean age 23.3 ± 3.9 years, recruited from the prenatal clinics of the "Maternidade-Escola Hilda Brandão - Santa Casa de Belo Horizonte/MG". Ambulatory blood pressure monitoring was done every three months (up to 14 weeks, between 18 and 28 weeks and between 32 and 40 weeks, using the SpaceLabs monitor, model 90207. RESULTS: a significant increase (p<0.01) in the 24-h systolic (115 and 104 mmHg), diastolic (73 and 61 mmHg) and average diurnal and nocturnal blood pressures (87 and 77 mmHg respectively), was noticed in the third trimester of pregnancy. Mother's diurnal blood pressure and heart rate (83, 84 and 87 mmHg; 94, 95 and 93 bpm) were significantly higher than the nocturnal measurements (72, 72 and 77 mmHg; 74, 79 and 79 bpm), in the three trimesters. Mother's heart frequency did not change during progress of pregnancy. CONCLUSION: increase in blood pressure during the third trimester of pregnancy could be shown. Maternal daily and diurnal heart rate did not change when the three trimesters were compared. The nocturnal heart rate was significantly lower in the first trimester as compared to the other trimesters.

PURPOSE: to compare intra- and postoperative results of vaginal hysterectomy with those of abdominal hysterectomy in women without genital prolapse or adnexal pathology. METHODS: a randomized, open clinical trial was conducted, involving 35 patients without genital prolapse scheduled for total hysterectomy due to benign disease, at IMIP, Recife, Brazil. These patients were randomly assigned to vaginal hysterectomy (19 patients) or abdominal hysterectomy (16 patients). Main outcome measures included estimated blood loss, rate of blood transfusion, duration of surgery, postoperative pain (intensity and analgesic requirement), time in hospital, postoperative complications, recovery time and patient satisfaction. Statistical analysis was performed using chi2, exact Fisher and Mann-Whitney tests at a 5% level of significance. RESULTS: estimated blood losses were significantly lower in vaginal hysterectomy (median of 520 mL) than in abdominal hysterectomy (median 902 mL). There was no blood transfusion among patients of the vaginal hysterectomy group, in contrast to 19% of the abdominal hysterectomy group. Duration of surgery was similar (median of 120 min in both groups). Postoperative pain, as measured by visual analog scale and analgesic requirement, was lower for vaginal hysterectomy than for abdominal hysterectomy. There was no statistically significant difference regarding frequency of postoperative complications. There was one case of infection in each group and one case of thrombosis in the vaginal hysterectomy group. Postoperative hospital stay was shorter in the vaginal group. Recovery time was significantly shorter in the vaginal group (median of 35 days) versus the abdominal group (median 40 days). Overall patient satisfaction with the operation was similar in the two groups. CONCLUSIONS: patients without genital prolapse submitted to vaginal hysterectomy for treatment of benign diseases had some advantages in relation to those submitted to abdominal hysterectomy: lower intraoperative blood loss, lower postoperative pain and faster recovery time. Vaginal hysterectomy may replace abdominal hysterectomy in most patients who require hysterectomy.

PURPOSE: to evaluate three embryo scoring systems specific for 3-day embryos and to correlate them with positive in vitro fertilization outcome. METHOD: retrospective study of the In Vitro Fertilization Program of the University Hospital, Faculty of Medicine of Ribeirão Preto, University of São Paulo. A total of 137 patients submitted to the transfer of 439 embryos were evaluated. The main outcomes measured were pregnancy and implantation rates. RESULTS: a significant difference in the three scoring systems was observed between pregnant (n=53) and non-pregnant (n=84) patients (p<0.0001). In the first embryo scoring system, in which cell number alone was used, higher pregnancy (70%) and implantation rates (42%) were observed when embryos with a mean blastomere number higher than 8 were transferred. Scoring system 2, based on a total four-point score (cleavage stage, blastomere number, fragmentation and symmetry), showed increased pregnancy (52.8%) and implantation rates (31%) for scores above 2. Scoring system 3, based on cell number and morphological criteria, also showed higher pregnancy and implantation rates with increasing average scores of the transferred embryos. CONCLUSION: the three scoring systems assessed in 3-day embryos were positively correlated with pregnancy and implantation rates.

PURPOSE: to quantitatively analyze the immunoreaction of monoclonal antibody Ki-67 in the mammary epithelium adjacent to fibroadenoma of premenopausal women treated with tamoxifen, for 50 days, at doses of 5, 10 and 20 mg/day. METHODS: we studied, prospectively, the effects of tamoxifen administered for 50 days, at doses of 5, 10 e 20 mg/day, by the immunoreaction of the Ki-67 (clone Ki-S5) monoclonal antibody on mammary epithelium adjacent to fibroadenoma in premenopausal women. We studied 58 patients in a double-blind trial who were divided into four groups: Group A (n=13; placebo), Group B (n=16; 5 mg/day tamoxifen), Group C (n=14; 10 mg/day) and Group D (n=15; 20 mg/day). All patients received the medication from the first day on of the menstrual cycle and biopsy was performed on the last day of the treatment. Cells stained and not stained by the immunoreagent were counted by optical microscopy (400X) with a digital image capturing system and image analysis. RESULTS: the average percentage of stained nuclei was calculated for all groups: Group A was 2.0 with a standard error (SE) of 0.3. In Group B it was 0.7 (SE=0.2); in Group C it was 0.4 (SE=0,2) and in Group D it was 0.1 (SE=0). Statistical analysis showed significant reductions between the groups (p<0.001), and Tukey's pairwise comparison test confirmed that there was a significant increase in the immunoreaction of the monoclonal Ki-67 antibody in groups B, C and D. CONCLUSIONS: tamoxifen, administered at doses of 5, 10 and 20 mg/day for 50 days, significantly reduced the immunoreaction of monoclonal Ki-67 in the mammary epithelium of premenopausal patients and there was no significant difference between the groups that received 5, 10 and 20 mg/day tamoxifen.

PURPOSE: to evaluate the diagnostic procedures used in women with Pap smear result of atypical glandular cells. PATIENTS AND METHODS: a prospective study with 159 women with atypical glandular cells was carried out between January and December 2000. All women were submitted to a new colpocytology and to colposcopy. Directed biopsy was performed in 50 cases, endocervical curettage in 21 and conization in 75. The performance of the diagnostic procedures was described by estimating the sensitivity, specificity, predictive values and likelihood ratio, considering histological results as gold standard. RESULTS: the histological evaluation showed 51 intraepithelial squamous lesions, 29 low grade and 22 high grade. Five women presented in situ adenocarcinoma and six patients presented invasive neoplasias. Colpocytology alone showed sensitivity and specificity of 88.5 and 39%, respectively, and colposcopy alone, 74 and 42%. The association of colpocytology with colposcopy increased the sensitivity to 98.4%, with a significantly lower specificity of 10%. Endocervical curettage showed low sensitivity (25%). CONCLUSION: the presence of atypical glandular cells on colpocytology was associated with preinvasive and invasive cervical lesions in 62.2% of the cases with histological evaluation. Repeating colpocytology and performing colposcopy allowed to select the women who needed histological evaluation. Conization was an adequate procedure when examination continued to show morphologic alterations.
