Purpose: to compare hospital costs between laparoscopically assisted vaginal hysterectomy (LAVH) and total abdominal hysterectomy (TAH), reporting the initial experience with the new approach in a communitary general hospital. Patients and Methods: eleven cases of LAVH and 23 of TAH, carried out from September 1998 to July 1999, were compared. Each patient's records and hospital charges were reviewed to collect the analyzed variables. Results: there was no statistical difference between the groups in relation to age, parity, and previous abdominal surgery. The main surgical indication for both groups was uterine leiomyomatosis. The LAVH group presented a shorter hospital stay with a median of one day, and the TAH group, of two days (p<0.01). LAVH showed to be 40.2% more expensive than TAH (p<0.01). Operating room charges contributed to the major part of hospital costs for both groups, corresponding to 79.8 and 57.9% of the total, for LAVH and TAH, respectively. LAVH infirmary charges were smaller than for TAH, with a statistically significant difference (p = 0.002). Conclusion: with shorter hospital stay and smaller infirmary costs, we demonstrated that LAVH provides better postoperative conditions and faster recovery than TAH. When done in a community general hospital, despite being more expensive, LAVH is an excellent option for uterine removal, and should be part of the therapeutical arsenal of gynecologic surgeons.

Purpose: to evaluate conization by the loop electrosurgical excision procedure (LEEP) for the diagnosis and treatment of cervical intraepithelial neoplasms (CIN), the importance of the margins and follow-up of these women. Methods: 95 women who underwent conization by LEEP for CIN and microinvasive carcinoma from January 1996 to December 1997 were evaluated. For statistical analysis, we used the kappa agreement coefficient and the tendency test of Cochran Armitage. Results: among 63 cases who underwent colposcopically directed biopsy before the conization, the cone presented the same grade of lesion in 20 and no residual disease in 8. The cone lesion presented a higher grade in 24 cases and one of them was a microinvasive carcinoma. Among the 25 women who underwent the cone biopsy with a previous biopsy suggestive of cervicitis or CIN 1, 56% had CIN 2 or 3 in the cone. Among the 32 women without previous biopsy, 15 had CIN 2 or 3, and four had microinvasive carcinoma in the cone. Regarding the margins of the cone, 25 cases presented some grade of CIN in the endocervical margins and 2/10 who underwent a second procedure presented residual disease on histological analysis. Among the 70 women with free cone margins, 2/4 who underwent a second procedure had residual disease on histological analysis. Conclusion: conization by LEEP without previous directed biopsy depends on the experience of the colposcopist. The second resection after LEEP for the diagnosis and treatment of CIN depends not only on the presence of disease in the cone margins but also on the follow-up. A second histological analysis is recommended in cases with microinvasive carcinoma and glandular lesion and affected margins.

PURPOSE: placental villitis has been correlated with perinatal infection, although a percentage of cases remains etiologically unknown. The present study was aimed at the systematic morphological study of placentas for imunohistochemical characterization of villitis and assessment of its possible correlation with maternal and fetal outcome. METHODS: a hundred and twenty-eight placentas were studied. Gross examination was performed and all collected fragments were analyzed microscopically by the hematoxylin-eosin method. Villits was classified according to the inflammatory degree in to mild, moderate and severe. The immunohistochemical study to identify infectious agents was performed using monoclonal antibodies against Toxoplasma gondii and Cytomegalovirus. For inflammatory cell phenotype identification monoclonal antibodies against CD68, CD57, CD3, and CD20 were used. Statistical analysis was performed with the variables: maternal age and fetal gestational age, fetal and placental weight, and fetal and maternal outcomes. To compare the two groups we used the Mann-Whitney test and for proportions we used the chi2 test. The differences in the mean values between the treatment groups were considered statistically significant when p<0.05 (5%). RESULTS: villitis was identified in 11.7% of the cases. In 40% of the cases the children were stillborn (p=0.003). One case showed positive staining for toxoplasmosis while the remaining cases were negative. Imunohistochemical staining showed CD68+ cells, PanT+ cells and negative CD57 and PanB cells. CONCLUSION: we concluded that the intensity of the inflammatory process in the placenta was correlated with the severity of the fetal disease. The inflammatory cells in the villitis focus were macrophages; however, we could not identify infectious agents correlated with the villitis.

PURPOSE: to assess risk factors for low Apgar score. METHODS: this was a cross-sectional study preformed in a random sample of patients admitted to a level III maternity hospital in 2001. The outcome was low Apgar score defined as an Apgar score 1-6 (study group) versus Apgar score 7-10 (control group) in the first minute of life. The first step was the evaluation of the association of each possible risk factor with low Apgar score. The second step was multivariate analysis with the backward stepwise logistic regression model. RESULTS: there were 39 (14%) depressed newborns which were compared to 238 (86%) not depressed babies. The final analysis (multivariate) showed an association between low Apgar score and previous case of stillbirth (OR=52.6), preterm labor threat (OR=33.8), low birth weight, less than 2,500 g body weight (OR=11.2) and previous cesarean section (OR=7.4). Some factors acted as a protection, including birth weight, in grams (OR=0.9), female sex of the newborn (OR=0.1), medical complications (OR=0.4) and prematurity (gestational age < 37 weeks, OR=0.1). CONCLUSION: the study may help in the identification of fetuses at great risk of asphyxia, allowing proper reference within the health system and planning of effective assistance in neonatal intensive care units.

PURPOSE: to find out the preference in regard to the way of delivery among primigravidae, as well as the reasons for their choice, in order to improve the quality of the doctor-patient relationship. METHODS: a qualitative-type study was conducted through analysis of the collective subject, including primigravidae attended from September to November 2003 at the emergency rooms of the hospital of the "Faculdade de Medicina de Jundiaí". A questionnaire, specially developed to accomplish the proposed objectives was applied. An informed and free consent, signed by the pregnant woman and one of the researchers in charge was obtained. This questionnaire was based on doubts of patients attended at this hospital some months before the trial. For the purpose of sample standardization, the patients' selection followed some inclusion criteria: age above 16, primigravidae that were receiving prenatal assistance and a post-informed and free consent. Mental disorders and clinical and/or obstetric pathologies that could interfere in the patient's choice were considered exclusion criteria. RESULTS: the studied population had as prevailing profile women in the third quarter of gestation, above 21 years of age, white, married and with completed school. Most of the women (90%) preferred vaginal delivery for the following main reasons: ease to be done (94%) and the fear of suffering and pain during the postpartum period caused by cesarean section. There was a relationship between older and married women and the preference for vaginal delivery, with no significant difference between races. CONCLUSION: these results show an enormous contrast between women's preference and the high cesarean section rates in Brazil. We conclude that there may be a lack of information and dialogue between the health professionals and patients about the possible difficulties, doubts and anxieties that involve the women's choice for a specific way of delivery. From an ethical point of view, we conclude that obstetricians should question every cesarean section indication and take into account the women's right to choose, without ignoring clinical criteria, when making the medical decision about the way of delivery.

PURPOSE: to assess the obstetric and perinatal outcomes in cases of term newborns in breech presentation, in patients with previous vaginal deliveries, comparing them to term newborns in vertex presentation. METHODS: 8,350 deliveries retrospectively from March 1998 to July 2003 were analysed. Of 419 deliveries (5.1%) in breech presentation, 58 cases were selected for the study (breech group), according to the following criteria: patients who had had one or more babies through vaginal delivery, gestational age ³37 weeks, no fetal malformation, no complications in the current pregnancy, birth weight between 2,500 and 3,750 g, and no previous cesarean section. The breech group was matched to 1,327 newborns in vertex position from pregnant women with no previous cesarean section (vertex group). Maternal age, parity, gestational age, delivery way, birth weight, meconium-stained amniotic fluid, 1- and 5-min Apgar score, need of neonatal intensive care unit, and small- and big-for-gestational age newborns were analyzed. Statistical analysis was performed by the c² test and by Student's t test, with the level of significance set at p<0.05. RESULTS: when breech and vertex groups were compared, they showed significant differences regarding the following variables: birth weight (3,091±538 g vs 3,250±497 g; p<0.01), vaginal delivery (63.8 vs 95.0%; p<0.0001), cesarean section (36.2 vs 5.0%; p<0,0001), and 1-min Apgar score (p<0.0001), respectively. CONCLUSIONS: we conclude that in term fetuses in breech position from pregnant women with previous vaginal deliveries, birth weight, delivery way, and 1-min Apgar score were different compared to fetuses in vertex position from women with the same characteristics.

PURPOSE: to compare the information obtained with pelvic and transvaginal ultrasonography (USG), hystero-salpingography (HSG), diagnostic hysteroscopy (HSC), pelvic nuclear magnetic resonance imaging (PNMR), three-dimensional hysterosonography (3D HSSNG), to optimize and simplify the investigation about cervical and corporeal uterine factors in conjugal infertility. METHODS: in the period between January and July 2003, fifty women reporting infertility for at least two years were submitted to USG, HSG, HSC, PNMR, and 3D HSSNG as tracking examinations for uterine factor diagnosis. The endocervical canal, as well as the endometrium, myometrium, and the presence of uterine malformations were investigated. The results of each examination were analyzed and compared. RESULTS: of the 50 women studied, 12 (24%) presented alteration in at least one of the examinations. When 3D HSSNG was compared to USG, 3D HSSNG provided additional information in 7 cases (58.3%); when compared to HSG, it provided additional information in 7 cases (58.3%); when compared to HSC, it provided additional information in 4 cases (32.1%), and when compared to PNMR, it provided additional information in 6 cases (50%). There were only two cases in which HSG detected alterations of the endocervical canal that were not visualized using 3D HSSNG. In the other cases 3D HSSNG imparted the same diagnosis; furthermore, it provided additional information in comparison to the other examinations. Statistical analysis using the kappa test demonstrated that the diagnoses obtained by 3D HSSNG were in agreement with those obtained with USG, HSG and PNMR (p<0,05). When the HSG and 3D HSSNG results were combined, all conditions associated with infertility could be precisely diagnosed, using only these examinations. CONCLUSION: the association of the HSG with 3D HSSNG may be sufficient for the diagnosis of cervical and corporeal uterine factors in infertility, reducing the number of examinations for each patient, the total cost, as well as the anxiety and the delay in treatment.

PURPOSE: to identify factors associated with the occurrence of hot flashes in climacteric women living in Campinas, São Paulo. METHODS: data bank secondary analysis of a cross-sectional descriptive population-based study. The selection of 456 women aged 45-60 years was done through area cluster sampling. Data were collected via home interviews using structured, pre-tested questionnaires provided by the International Health Foundation/International Menopause Society and by the North American Menopause Society and adapted by the authors. The analyzed variables were age, race, use of contraceptive methods and hormonal therapy, tubal ligation, body mass index, menopausal status, time since menopause, hysterectomy, and cigarette smoking. Statistical analysis was performed using the mean, median and the prevalence ratio (PR). Multiple logistic regression was performed using the stepwise selection process with a 95% confidence interval (95% CI). RESULTS: bivariate analysis showed that postmenopausal women (PR: 1.42, CI 95%: 1.06-1.90) and those who were submitted to hysterectomy (PR: 1.50, CI 95%: 1.05-2.14) had a significantly greater chance of presenting hot flashes. After applying multiple regression analysis, there was no significant association between hot flashes and any of the evaluated variables. CONCLUSION: results were consistent with previous studies. Many doubts still exist about which factors are associated with hot flashes.
