PURPOSE: to evaluate the association between p53 and Ki-67 expression in the tumor and clinicopathological features in patients with carcinoma of the cervix. METHODS: samples were taken from the tumor of 36 patients with stage IB (FIGO) cervical carcinoma submitted to radical hysterectomy. Tissue samples were taken from the tumor, fixed in formalin and embedded in paraffin. The specimens were analyzed by histopathology (hematoxylin and eosin) and immunohistochemically evaluated using monoclonal antibodies for p53 and Ki-67. Data were analyzed statistically by the chi2 test to evaluate eventual differences between the groups. RESULTS: the age of the patients ranged from 27 to 73 years (48.7±10.4 years). Clinical stage (FIGO) was IB1 in 27 cases (75%) and IB2 in 9 cases (25%). A positive tumoral expression of the p53 protein was found in half of the cases. In relation to the Ki-67 expression, a high cell proliferation index was shown in 73.3% of the cases. There was no association between tumoral p53 and Ki-67 expression with age (p=0.091 and 0.900), clinical stage (p=0.054 and 0.667), histological classification (p=0.674 and 0.674), grade of differentiation (p=0.070 and 0.282), presence of lymphatic vascular space invasion (p=0.248 and 0.667), parametrial involvement (p=0.729 and 0.763) and pelvic lymph node metastasis (p=0.729 and 0.636, respectively). CONCLUSIONS: tumoral expression of p53 and Ki-67 was not associated with the clinicopathological features in patients with stage IB carcinoma of the cervix.

PURPOSE: to evaluate the influence of hyperthyroidism during pregnancy and the necessity of changing antithyroid drug dose in this period and after delivery. METHODS: prospective evaluation of clinical and laboratorial findings of thirteen pregnancies in eleven pregnant women with hyperthyroidism due to Graves' disease. These women were evaluated through TSH and serum free T4 at each trimester or four weeks after setting thionamide dosage. The goal was to maintain free T4 in the superior third of the normal range using the lowest possible thionamide dose. RESULTS: the mean age at the beginning of the pregnancy was 31.1 years (23 to 41). The mean dosage of thionamide was reduced in eight pregnancies (69.5%) and, in two, the drug was discontinued. Before pregnancy, mean propylthiouracil dose was 400 mg/day (200-900) and mean methimazole dose was 45 mg/day (20-60). After delivery, antithyroid drug dose was 200 and 30 mg/day, respectively. One patient presented premature labor (at 36 weeks) and another, a newborn small for gestational age (2.000 g at 38 weeks). There was one stillborn. There were no miscarriages or congenital anomalies. After labor, antithyroid drug dose was increased in seven patients and in the others the dose was maintained. CONCLUSIONS: we suggest close follow-up of pregnant women with hyperthyroidism and progressive reduction of thionamide dose during pregnancy to avoid maternal hypothyroidism and its consequences to fetal development. After labor, these women must be evaluated regarding their thyroid function because hyperthyroidism can worsen. Thionamide use is safe for the patients and their offspring.

PURPOSES: to analyze the frequency, associated risk factors for the occurrence of spina bifida and differences between the newborns carrying this malformation and the newborns' morbidities. METHODS: data were obtained through interview of 47 cases and 47 controls, born in the five maternities of the city of Pelotas, during the period from January 1, 1990 to December 31, 2003. This is a population-based case-control study, comprising all births occurred in hospitals. The control was the normal newborn that was born after each case with spina bifida. All data were obtained by using the model ECLAMC questionnaire. The planning of analysis of data included the use of the Student's t test, chi² and odds ratio. RESULTS: in this period there were approximately 77,000 births. Of these, 1,043 (1.35%) presented some type of congenital malformation. Among these, 47 of 162 anomalies of the neural tube (29%) were spina bifida cases. Significant differences have been found in the number of previous stillborn babies, as well as a higher rate of spina bifida cases in females. In this study, many factors such as the use of medical drugs; acute and chronic illnesses; number of gestations; age, education and occupation of the parents, among others, did not influence the occurrence of spina bifida. CONCLUSIONS: spina bifida must be considered as an important factor of risk for perinatal morbidity, and its occurrence is associated with a history of previous stillborn babies.

PURPOSE: to evaluate the effectiveness of the "global active stretching" (GAS) method and the routine medical recommendations for lumbar and/or posterior pelvic pain in pregnancy. METHODS: sixty-nine pregnant women who experienced lumbar or posterior pelvic pain were selected and identified through a randomized controlled clinical trial and were randomly divided into two groups. One group practiced GAS-oriented exercises and the other followed the routine medical recommendations. The pregnant women were followed up for eight weeks. The severity of pain was estimated by the visual analog scale and posterior pelvic pain and lumbar back pain were confirmed by provocation tests. RESULTS: after treatment, 61% (p<0.01) of the women of the GAS group reported no pain at the lumbar/or posterior pelvic area compared with 11% (p=0.50) of the group who followed routine medical recommendations. CONCLUSIONS: the GAS method relieved and diminished the intensity of lumbar and/or pelvic pains more effectively than routine medical recommendations.

PURPOSE: the proposal of the present study was to translate and to validate King's Health Questionnaire (KHQ) for Brazilian women with urinary incontinence. METHODS: a hundred and thirty-four patients with urinary incontinence, confirmed by urodynamic study, were enrolled from the outpatient clinic of Uroginecology. Initially, we translated the KHQ into the Brazilian Portuguese language in agreement with international criteria. Due to language and cultural differences we performed a cultural, structural, conceptual, and semantic adaptation of the KHQ, in order to make sure that patients were able to fully understand the questions. All patients answered the KHQ twice on the same day, within an interval of 30 min, applied by two different interviewers. After 7 to 14 days, on a second visit, the questionnaire was applied again. Reliability (intra- and interobserver internal consistency), construct and discriminative validity were tested. RESULTS: several cultural adaptations were necessary until we reached the final version. The intra-observer internal consistency (alpha of Cronbach) of the several dimensions varied from moderate to high (0.77-0.90), and the interobserver internal consistency varied from 0.66 to 0.94. Moderate to strong correlation was detected among the specific KHQ urinary incontinence dominions and clinical urinary incontinence manifestations known to affect the quality of life of these patients. CONCLUSION: KHQ was adapted to the Portuguese language and to the Brazilian culture, showing great reliability and validity. It should be included and used in any Brazilian urinary incontinence clinical trial.

PURPOSE: to estimate the prevalence of HPV and its genotypes in HIV-infected and non-infected women, using the Polymerase Chain Reaction (PCR) technique. METHODS: a sectional study with 79 enrolled women: a study group, with 41 HIV-infected women, and a control group, with 38 non-infected women attended at a Basic Health Unit. All were submitted to a serologic test for the detection of HIV and spontaneously looked for gynecological attendance at those units, for the first time. They answered a standard questionnaire and were submitted to a gynecological examination with a cervical swab and specimen for the detection of DNA-HPV and its genotypes. Statistical analysis was performed using Kruskal-Wallis, chi2 or Fisher's exact tests. Statistical significance was considered at p<0.05. RESULTS: the demographic characteristics, obstetric and gynecological previous history were similar in both groups except for previous STD, but different as to the gynecological examination and cervical cytological analysis. The presence of DNA-HPV was significantly different (p<0.05) in the two groups. Among HIV-infected patients, 73.2% presented DNA-HPV positive results, as compared with 23.8% of non-infected women (OR=8.79; 95% IC: 2.83 28.37). Concerning HPV genotypes, there was no clear predominance of a specific HPV subtype in the HIV-infected or in the HIV non-infected groups, and the frequency of unidentified types was similar in both groups. Non-significant predominance of HPV multiple infections (p>0.05) was detected in the HIV-infected women (50.0%) and the most frequently found combination was of types 6, 11 and 16. HPV simple infection occurred in 66.6% of HIV-non-infected patients. The most frequent type found in both groups was 16, representing 44% of all the simple infections in both groups. CONCLUSIONS: HIV-infected women showed higher DNA-HPV prevalence in the uterine cervix, as compared to non-infected women. There was no difference in the predominance of specific types of HPV when both groups were compared. There was a tendency to HPV multiple infections in the HIV-infected women, whereas simple infection predominated in the non-infected patients.

PURPOSE: to verify if the high frequency of vaginal intercourses and the use of doushing interferes with vaginal microbiota. METHODS: ninety-seven women were examined at a health center located in the prostitution area of the city of Campinas, and evaluated in a prospective cross-sectional study. Anamnesis determined the frequency of vaginal intercourse and the use of douching in the 44 sex professionals and 53 non-professionals studied. The vaginal content was collected with a sterile Dacron swab, from the right vaginal wall, and placed on to two glass laminas. The vaginal microbiota smear stained by the Gram technique was studied with light microcopy using immersion lens and the data were analyzed. The sex professionals and non-professionals presented mean age of 24.9±6.4 and 31.5±9.7, habit of smoking in 52.2 and 24.5%, the use of vaginal lubricants in 56.8 and 0%, and the use of condoms in 100 and 41.5% of the cases, respectively. RESULTS: only 1.8% of the women in the control group had seven or more sexual intercourses per week, contrasting evidently with the sex professionals (97.7%). There were no significant differences regarding race, educational level and number of pregnancies. Bacterial vaginosis and abnormal vaginal flora were more observed in sex professionals (p=0.02 and 0.001) and were associated with the high frequency (seven times or more) of weekly vaginal intercourses (p=0.04 and 0.001). Cytolytic vaginosis was more related to non-professionals (p=0.04) and to a lower frequency of sexual intercourses (p=0.04). The use of doushing was more common in the sex professionals (p=0.002). However, this practice was not associated either with the vaginal microbiota problems or with the presence of vulvovaginitis. CONCLUSIONS: sex professionals with seven or more sexual intercourses per week presented a higher frequency of bacterial vaginosis and abnormal vaginal flora. The doushing habit did not interfere with the vaginal environment ecosystem of the studied women.

PURPOSE: to evaluate ophthalmic and retinal central artery Doppler indices during the second and third trimesters of normal pregnancy and to compare the right with left eye Doppler indices of normotensive women. METHODS: a cross-sectional study which evaluated central retinal and ophthalmic artery Doppler velocimetry values of 51 normal pregnant women, in the 20th to 38th week of gestation. The following values were analyzed: pulsatility and resistance indexes (PI, RI), peak systolic and end-diastolic flow velocity (PSV, EDFV) and peak velocity ratio (PVR). The Doppler indices in the right and left eyes were studied by the median. The paired Student's t test was used to confront the right and left eye values and the Pearson linear correlation analysis was performed to study the value changes throughout the gestation, with the level of significance set at 5%. RESULTS: Doppler velocimetry indices of ophthalmic and central retinal arteries (median values) were, respectively: PI=1.83; RI=0.78; PSV=34.20; EDFV=6.80; PVR=0.48 and PI=1.34; RI=0.70; PSV=7.40; EDFV=2.10. There was no significant difference between the right and left side Doppler values. Linear correlation analysis showed no association between the arterial values and pregnancy age. CONCLUSION: the unilateral analysis of ophthalmic and central retinal artery Doppler velocimetry values can be used in systemic maternal disease. There is no significant change in ophthalmic and central retinal artery Doppler velocimetry values throughout normal pregnancy.
