PURPOSE: To analyze the association of pregnancy in adolescence and prematurity. METHODS: The study included all the patients who delivered at a teaching hospital in Maranhão State, from July to December 2006. The patients were divided into two groups: adolescents (10 to 19 years old) and adults (20 to 34 years old). The variables studied were: educational level, marital status, number of prenatal visits, gestational age at the onset of prenatal care, duration of gestation, delivery route and birth weight. Statistical analysis was performed using the Epi-Info software, version 3.4.1, and the associations between variables were analyzed by the odds ratio (OR), with a 95% confidence interval (CI). Models of logistic regression were also used. The level of significance adopted was 0.05. RESULTS: The study evaluated 1,978 patients. The frequency of deliveries in adolescents was 25.4%. This group presented low educational level, no mates, low number of prenatal visits, late onset of prenatal care, low birth weight and prematurity. In the analysis of prematurity as the outcome variable, there was a clear association with low number of prenatal visits (OR 3.0; 95%CI 2.2-4.0) and late onset of prenatal care (OR 1.9; 95%CI 1.3-2.6) and low educational level (OR 1.9; 95%CI 1.4-2.5) related to adolescence (OR 1.5; 95%CI 1.1-1.9). The incidence of caesarean delivery was significantly lower among adolescents (33.3%) than among adults (49.4%), with a lower association with pre-eclampsia and cephalo-pelvic disproportion. CONCLUSIONS: Pregnancy in adolescence was associated with late onset of prenatal care and low number of visits, as well as low educational level, low birth weight, prematurity and a lower incidence of cephalo-pelvic disproportion and pre-eclampsia.

The offer of the maternal breast to the baby is an unquestionable right of mothers and their children, and all efforts should bemade to promote, follow and maintain exclusive breastfeeding for up to 6months and supplement it until the child completes 2 years of age. Many publications are available in the literature about the qualities of breast milk, its benefits and health repercussions, stimulating the practice of breastfeeding and supporting campaigns for its implementation. However, although it is widely known that breastfeeding is an important step in the reproductive process of women and its practice offers benefits to both mother and child, most of the available information highlights the benefits of breast milk for children, while mention of the effects of breastfeeding on the health of the mother is usually neglected. Thus, the objective of the present study is to highlight the multiple benefits of breastfeeding for the physical and emotional health of the nursing mother. The authors consulted articles published in the databases PubMed, Virtual Health Library andWeb of Science using the keywords breastfeeding, breast milk, lactation and maternal health.

OBJECTIVE: to assess through Dopllerfluxometry the S/A ratio of the ductus venosus and determine the cut-off point to identify preterm fetuses with the 'brain sparing phenomenon". METHOD: a cross-sectional study was performed in 60 pregnant women that presented the "brain sparing phenomenon" (umbilical cerebral ratio >1) and gestational age between 25 and 33 weeks. The following parameters were studied: S/A ratio of the ductus venosus, pH and base excess (BE) of a fetal blood sample collected from the umbilical vein immediately after birth. The fetuses were classified according to the gas analysis result. They were considered abnormal when pH <7.20 and BE < -6 mmol/l. A receiver operator characteristic (ROC) curve analysis was performed to examine the relationship between S/A ratio and fetal acidemia. RESULTS: sixty pregnant women in the period of January 1998 to January 2003 were selected. In the moment of the study the gestational age varied from 25 to 33 weeks, with an average of 29.7 weeks (±1.8 weeks). All of the fetuses presented the "brain sparing phenomenon". Among them 14 presented abnormal gas analysis at birth and 46 presented normal gas analysis. The prevalence of fetuses with abnormal gas analysis in the studied material was 23.33%. Significant association was observed between the abnormal ductus venosus velocimetry and abnormal gas analysis at birth (chi2 = 784.44, p < 0.00001) in preterm fetuses with "brain sparing phenomenon". The best cut-off point of the S/A ratio (where the ROC curves bent) was 3.4. CONCLUSION: fetal acidemia in preterm fetuses with "brain sparing phenomenon" may be noninvasively identified by Doppler measurement of the ductus venosus when the S/A rises above 3.4.

Purpose: to compare histopathology and polymerase chain reaction (PCR) for the diagnosis of human papillomavirus (HPV) in cervical lesions of human immunodeficiency virus (HIV)-seropositive women. Methods: fifty-two HIV-seropositive women with suspected HPV cervical lesions were studied. Cervical scrapes were collected for PCR and colposcopy-guided biopsy was made for the histopathologic study. Three samples were disqualified for PCR, leaving a study population of 49 women. Results: the prevalence of HPV was 53% by histopathology and 85.7% by PCR. Among the 42 patients in whom HPV was detected by PCR, 26 were confirmed by histopathology (sensitivity = 61.9%). This method gave no false-positives (specificity = 100%), with 100% of positive prediction. Compared to PCR, the histopathology had: positive predcitive value = 100% and negative predcitive value = 30.4%. Among the 26 patients with HPV-positive biopsy, 15 (57.7%) had cervical intraepithelial neoplasia (CIN); relative risk = 13.3. Conclusion: histopathology was 100% correct for HPV-infection diagnosis. It means that when the biopsy is positive, HPV will be present, confirming the clinical suspicion. However, the low sensitivity excludes histopathology as a screening examination in this group of women.

PURPOSE: to evaluate the frequency of lower urinary tract symptoms (LUTS), three years after delivery in women previously interviewed at the third gestation trimester, and to compare the gestation and delivery impact on LUTS, analyzing the social and hygienic discomfort associated with micturition complaints. METHODS: analytical prospective study. In 2003, 340 pregnant women were selected in the pre-natal outpatient unit, and asked to answer a pre-tested questionnaire about LUTS and obstetric data. Three years after delivery, it was possible to get in touch by telephone with 120 of the 340 women who had been interviewed in the first study. They answered a second questionnaire about obstetric data, LUTS and its social impact. LUTS have been divided into stress urinary incontinence (SUI) and irritative urinary symptoms (IUS). McNemar's and chi-square tests were used for statistical analysis (p<0.05). RESULTS: SUI and nocturia have occurred in 57.5 and 80% of the pregnant women and the appearance of those symptoms after delivery, in 13.7 and 16.7%, respectively. Urge urinary incontinence has been significantly more frequent after delivery (30.5%) than in gestation (20.8%). Only 35.6% of the women with IUS presented social discomfort, but this rate has gone up to 91.4% in women with IUS associated with SUI. CONCLUSIONS: gestation, more than delivery, was associated with the appearance of SUI and nocturia, while the urge urinary incontinence was significantly higher after delivery. Most of the women have mentioned that SUI causes social problems.

Pelvic organ prolapse (POP) is a major health issue worldwide, affecting 6- 8% of women. The most affected site is the anterior vaginal wall. Multiple procedures and surgical techniques have been used,with or without the use of vaginalmeshes, due to common treatment failure, reoperations, and complication rates in some studies.
Systematic review of the literature and meta-analysis regarding the use of vaginal mesh in anterior vaginal wall prolapse was performed. A total of 115 papers were retrieved after using the medical subject headings (MESH) terms: 'anterior pelvic organ prolapse OR cystocele AND surgery AND (mesh or colporrhaphy)' in the PubMed database. Exclusion criteria were: follow-up shorter than 1 year, use of biological or absorbable meshes, and inclusion of other vaginal wall prolapses. Studies were put in a data chart by two independent editors; results found in at least two studies were grouped for analysis.
After the review of the titles by two independent editors, 70 studies were discarded, and after abstract assessment, 18 trials were eligible for full text screening. For final screening and meta-analysis, after applying the Jadad score (> 2), 12 studies were included. Objective cure was greater in the mesh surgery group (odds ratio [OR] = 1,28 [1,07-1,53]), which also had greater blood loss (mean deviation [MD] = 45,98 [9,72-82,25]), longer surgery time (MD = 15,08 [0,48-29,67]), but less prolapse recurrence (OR = 0,22 [01,3-0,38]). Dyspareunia, symptom resolution and reoperation rates were not statistically different between groups. Quality of life (QOL) assessment through the pelvic organ prolapse/urinary incontinence sexual questionnaire (PISQ-12), the pelvic floor distress inventory (PFDI-20), the pelvic floor impact questionnaire (PFIQ-7), and the perceived quality of life scale (PQOL) was not significantly different.
Anterior vaginal prolapse mesh surgery has greater anatomic cure rates and less recurrence, although there were no differences regarding subjective cure, reoperation rates and quality of life. Furthermore, mesh surgery was associated with longer surgical time and greater blood loss. Mesh use should be individualized, considering prior history and risk factors for recurrence.

, , , The present paper reports on the local treatment of breast cancer from a historical perspective. A search for articles written in English was made in the Medline and EMBASE databases, and 40 papers were selected. Over the past 10 years, various randomized, controlled clinical trials on the local treatment of breast cancer indicated that patients with the samemolecular subtypemay receive different individualized surgical treatments aimed atoptimizing systemic adjuvant therapy. With a view to retaining the gainsmade in diseasefree and overall survival, surgical techniques have advanced from radical surgery to conservative mastectomies, thus reducing sequelae, while adjuvant and neoadjuvant therapies have contributed toward controlling the disease, both distant metastases and local recurrence. Current studies evaluate whether future breast cancer therapy may even succeed in eliminating surgery to the breast and axilla altogether.
