PURPOSE: to identify the microbial charge present in reusable trocars used in gynecological laparoscopies. METHODS: a descriptive exploratory study. An amount of 57 trocars, 30 with 10 mm of diameter and 27 with 5 mm, have been collected from the surgical unit, immediately after the surgery and placed in a sterilized recipient, in which 250 mL of sterile distilled water was added. Then, the trocars were agitated for the drainage of particles and to obtain a wash-out fluid to be analyzed. After being filtered through 0.22 µm cellulose membrane, the residue was placed on blood agar plates with a sterilized forceps. Following incubation, microbiological analysis has been done to count the number of colonies and further identify the microorganisms, using standard laboratorial techniques. RESULTS: microbial charge was recovered from 47.4% of the trocars analyzed. Among those, 45.6% presented 1 to 100 growing colonies. Fourteen types of microorganisms have been identified, among which the more frequently isolated were coagulase-negative Staphylococcus (28%) and Bacillus sp (21%), Aeromonas hydrophila, Alcaligenes sp, Candida parapsilosis, and enterobacteries were also identified. CONCLUSIONS: the study has demonstrated that the microbial challenge faced by the technician responsible for the cleaning and sterilization of trocars is low, as compared to the challenge imposed by biological markers. Nevertheless, it may be not inferred that the risks for infectious complications for patients are minimal.

PURPOSE: The adaptation into Portuguese and evaluation of the Index of Scientific Quality (ISQ) questionnaire applicability's in texts presented by Brazilian magazines on woman's health. METHODS: A transversal cohort study. Texts published from August 2005 to July 2007, in the main weekly magazines Veja, Época and Isto é, were collected. The questionnaire used is composed of eight items, with five alternatives each, measuring the applicability, opinion degree, validity and implications of the finding, precision, coherence and relevance of the data, besides a global item summarizing all the other items. ISQ was translated, retro-translated and submitted to a pilot test till the final version, which was used by two medical doctors and two journalists. After the texts analysis', the internal consistency of the questionnaire items was checked through Cronbach's alpha coefficient, and the inter and intra-observer agreement, for each item, by Kappa's index. RESULTS: The sample was composed by 80 articles. The internal consistency of items has varied from 0.81 to 0.96. The inter-evaluators' agreement ranged from -0.03 to 0.48, and the intra-observer varied from 0.27 to 0.34 (CI 95%). CONCLUSION: The questionnaire items have adequately measured the scientific quality of the texts, but the low agreement inter and intra-observers points to the need for further studies to assess the Brazilian version of ISQ.

PURPOSE: to analyze histomorphometric consequences of the uterine arteries embolization (UAE) in the uterine tissue, especially by collagen tissue quantification through uterine biopsy, before and after treatment of uterine leiomyoma. METHODS: 15 patients with symptomatic leyomioma and/or infertility, submitted to UAE, participated in the study according to the study exclusion criteria, after having signed an informed consent. Uterine biopsy was performed in the secretory phase of the menstrual cycle, before and three months after the procedure, to evaluate the collagen. After the histological processing of the material, 3 µ slices were prepared, some of them dyed with hematoxiline-eosin (HE) and others with the specific dye for collagen fibers (Picrosirius red). Then, the slides were examined and interpreted, and the collagen quantified. The amount was calculated as the percent of the area composed by collagen, and the result expressed in mean±standard deviation (SD). Data has then been submitted to statistical analysis by Student's paired t test (p<0.05). RESULTS: the presence of smooth muscle cells was observed in the biopsies performed before the treatment, surrounded by a rich network of collagen fibers, which are part of the tumor, blood vessels and fibroblast nuclei. On the slides of biopsies performed after the treatment, it was observed the presence of widespread coagulation necrosis, vascular thrombosis, calcification and lymphoplasmocitary infiltration areas and clear reduction of the collagen component. The percentage of collagen fibers was higher in the pre-UAE group (84.07±1.41), than in the post-UAE (81.05±1.50) group, with p<0.0001, and 95% confidence interval (CI95%) from 2.080 to 3.827. CONCLUSION: the quantitative and qualitative collagen reduction clearly shows that the proposed treatment is efficient in reducing the tumoral mass, composed mainly by collagen fibers intermingled with neoplasic smooth muscle cells. Nevertheless, complementary studies are needed to investigate the functional and biological consequences of these histological changes.

PURPOSE: to evaluate the results of treatment to which patients with high grade intraepithelial cervical neoplasia (HSIL) are submitted, as well as their follow-up during pregnancy. METHODS: retrospective study based on the review of the medical report of 30 patients with diagnosis of high-grade squamous intraepithelial lesions (HSIL) during pregnancy and attended to at a tertiary hospital in southern Brazil from 1990 to 2002. Diagnosis was performed by colposcopy and biopsy, with repetition of the colposcopy during the pregnancy and after delivery. The diagnoses of regression and progression of lesions were evaluated. RESULTS: from 30 patients, 3 were excluded of the sample because the diagnosis of high-grade squamous intraepithelial lesions (HSIL) was not confirmed by the colposcopy with biopsia. Four patients were submitted to treatment during pregnancy, and one of them presented preterm delivery at the 32nd week. Twenty-three patients were submitted to expectant treatment, underwent a new colposcopy and biopsy, and then were submitted to conisation surgery at about the 11th week after the end of pregnancy. In 7.4% of the cases, there was lesion regression in the surgical specimen. CONCLUSIONS: all patients with diagnosis should be submitted to colposcopy and biopsy to exclude the possibility of invasive lesion. The expectant procedure for intraepithelial lesions is the most widely chosen and safe due to the possibility of regression in the postpartum period.

PURPOSE: to describe the genetic diversity of HIV-1 isolates from serum positive women followed up at a reference center. METHODS: transversal study, including 96 women with two ELISA serological tests and a Western Blot confirmatory test. The viral charge was determined by the b-DNA kit, and the counting of T CD4 and T CD8 lymphocytes, by the Excalibur flow cytometry, from the samples of peripheral blood. The extraction and purification of pro-viral DNA was performed by the polymerase (PCR) chain reaction, using the QIAamp Blood kit (Qiagen Inc., Chatsworth, CA, U.S.A.). Sequencing of the pol region was done in 52 isolates with the 3100 Genetic Analyzer (Applied Biosystems Inc., Foster City, CA), and the genotyping was assessed by the Rega Subtyping Tool. The resistance pattern to anti-retrovirals (ARV) was inferred by the algorithm from the Stanford HIV Resistance data bank. Participants' clinical stages were defined as A, B or C, according to the criteria established by the Center for Diseases Control (CDC). For statistical analysis, the χ2 test was used for the categorical variables and the Student's t test, for the numerical variables. RESULTS: The average age of the sample, the disease and treatment average duration were respectively: 33.7 years old, 3.8 and 2.5 years. The viral charge average was log10 2.3 copies/mL; the T CD4 e T CD8 lymphocytes, 494.9 cells/µL and 1126.4 cells/µL. Concerning the clinical stage, 30 women were in stage A, 47 in B and 19 in C. Sequencing from the 52 isolates found 33 of B subtype, 4 of F, 1 of C and 14 of BF recombinant. The analysis of resistance to ARV has shown 39 (75.0%) susceptible isolates, 13 (25.0%) resistant to reversal transcriptase inhibitors (RTIN), and 3 (5.7%) resistant to protease inhibitor (PI). CONCLUSIONS: There has been a large variety of HIV-1 and a high percentage of isolates resistant to ARV in the studied sample.

PURPOSES: to evaluate the influence of maternal hemoglobin (Hb) levels in the patterns of fetal heart rate (FHR) and in the fetal biophysical profile (FBP) in term gestations. METHODS: pregnant women with anemia (Hb<11.0 g/dL) were prospectively evaluated between the 36th and the 40th week of gestation, from January 2008 to March 2009. The Control Group was composed of term and healthy pregnant women, with normal values of hemoglobin (Hb>11,0 g/dL). Cases of anomalies or fetal growing restrictions were excluded. The FHR evaluation was performed by computerized cardiotocography (8002 System-Sonicaid), and by record analysis during 30 minutes of exam. The FBP was done in all the patients. Student's, χ2 and Fisher's exact tests were used, with 0.05 significance level. RESULTS: The average of maternal Hb in the group with anemia (n=18) was 9.4 g/dL (DP=1.4 g/dL), and in the control group, 12.4g/dL (DP=1.3 g/dL). There has been no significant mean differences between groups concerning the cardiotocography parameters, respectively: basal FHR(131.3 versus 133.7 bpm, p=0.5), FHR accelerations > 10b pm (7.9 versus 8.2, p=0.866), FHR accelerations > 15 bpm (5.2 versus. 5.4, p=0.9), episodes of high variation of the FHR (17.1 versus 15.5 min, p=0,5), episodes of variation of the FHR (4.4 versus 3.6 min, p=06), and short term variation (10.5 versus 10.9 ms, p=0.5). In both groups, all patients presented normal FBP. CONCLUSIONS: this study suggests that light or moderate maternal anemia, without other maternal or fetal comorbidity, is not associated with abnormalities in the parameters of fetal biophysical profile and of the FHR analyzed by computerized cardiotocography.

The main source of inhibin B in women is the growing follicle granulosa cells, while inhibin A is mainly produced by the corpus luteum and the placenta. In infertile women submitted to therapies of assisted reproduction, inhibin B has shown to be useful to predict a poor ovulatory response, though it has not yet overcome the performance of other markers. In the pre-natal screening of the Down syndrome, inhibin A has been repeatedly confirmed as useful in the second trimester and has also started to be considered in the first trimester test battery. Besides the two applications above, the dosage of total inhibin may contribute to the identification of cases of autoimmune ovarian insufficiency. Total inhibin may also be an auxiliary marker in the diagnosis of ovarian epithelial tumors, while the amount of inhibin B helps in the diagnosis of granulosa cells tumors. The use of inhibin A may be extended to the evaluation of pregnant women with risk of abortion, with a history of repeated abortion, with increased risk of pre-eclampsia, or even in the first days of follow-up of hydatiform mole post-emptying. All those applications are still under study, but with a real possibility of helping to extend the diagnostic spectrum of inhibin dosage in Gynecology and Obstetrics.
