PURPOSE: to describe the frequency of precursor lesions of cervical cancer in 15 to 29-year-old women, associating the degree of damage with the epidemiologic characteristics and associated risk factors. METHODS: a transverse study was performed, where the precursor lesions of cervical cancer were investigated through Papanicolaou test in 15 to 29 year-old women with active sexual life, living in Rio Branco (AC), in the period from January to September 2001. The investigated data included epidemiologic information, risk factors and physical-ginecological examination results, including Schiller test and smears for cytopathologic test. RESULTS: of the 2,397 women studied, 155 (6.4%) showed some kind of cellular epithelial alteration, 146 (94.2%) squamous lesions and 9 (5.8%) glandular lesions. In 15 to 19 year old women, the frequency (6.9%) of cellular epithelial alteration was similar to that observed in 20 to 29-year-old women (p>0.65). These alterations were associated with low educational level (p<0.003), with the number of sexual partners (p<0.04), with STD history (p<0.001) and smoking habits (p<0.01). CONCLUSION: the high frequency of precursor lesions in an age lower than expected, and following an epidemiologic pattern observed in other phases of women's life, shows the early exposure to risk factors, which anticipates the development of cervical cancer.

PURPOSE: to assess the concordance of cytological tumoral and nuclear grading systems on fine needle aspiration biopsies of breast carcinoma with histological specimens and compare them to identify the best results. METHODS: cytohistological agreement was evaluated in a retrospective study of 50 cases of fine needle aspiration biopsies of histologically confirmed invasive ductal carcinoma of the breast, with 5 grading systems being applied for comparative purposes.The classifications were divided according to criteria of tumoral grading (nuclear and architectural criteria - Mouriquand and Guilford systems) and nuclear criteria (Black modified by Fisher (BM), simplified Black system (SB) and Hunt system). The grading systems used for histological analysis were those of Scarff-Bloom-Richardson modified by Elston (SBR modified) for tumor evaluation and the BM systems for nuclear evaluation. RESULT: the cytological grading systems that showed best agreement were BM and SB based on nuclear criteria (anisonucleosis, size, mitosis, and chromatin). Among the cytological grading systems based on nuclear and architectural criteria (combined), Guilford's classification showed the best agreement, possibly due to the larger number of variables used, which permitted a smaller margin of error. CONCLUSION: the methods evaluated in the present study can be considered reasonable as cytological grading systems.

PURPOSE: to test the efficacy of and tolerance to Schinus terebinthifolius Raddi gel in the treatment of bacterial vaginosis. METHODS: forty-eight women with symptomatic bacterial vaginosis (according to Amsel's criteria) were enrolled in a randomized, double-blind, controlled trial comparing Schinus terebinthifolius Raddi gel (25 cases) with placebo (23 cases). The main outcome parameters were: rate of cure, presence of lactobacilli in Pap smear after treatment and side effects. Statistical analysis was performed using the chi2 and the Fisher exact test at 5% level of significance. RESULTS: using Amsel's clinical parameters of bacterial vaginosis, the cure rate was 84% in the Schinus group and 47.8% in the placebo group (p=0.008). A significant increase in the frequency of lactobacilli was observed in the Pap smear of the group treated with Schinus (43.5%) compared to the patient group (4.3%) (p=0.002). Treatment-related adverse events were not frequent in either group. CONCLUSIOS: the present study indicates that Schinus vaginal gel is effective and safe in the treatment of bacterial vaginosis. In addition, potential beneficial effects on the vaginal flora are suggested.

Purpose: to compare bone mineral density (BMD) of postmenopausal women with and without the antecedent of tubal ligation, as well as to evaluate the associated factors that affect the bone mineral density of femur and lumbar spine of both groups. Methods: 70 postmenopausal women in each group were analyzed at CAISM-UNICAMP, during the year of 1998. All women answered a questionnaire about some clinical and reproductive characteristics and underwent bone densitometry (Lunar DPX) to measure bone mineral density of the femur and lumbar spine. Statistical analyses were performed using Student's t-test, Fisher`s exact test, Pearson c² test, Bonferroni`s test and multiple regression analysis. Results: mean age of patients was 53.2 years and for controls it was 52.6 years. Mean age of 48 years at menopause was similar in both groups. Mean age at tubal ligation surgery was 33.7 years and time since surgery was 18 years. The multiple comparison of the average bone mineral density of femur and lumbar spine did not show statistical differences between the groups. The percentage distribution of the T-score categories of femur and lumbar spine, classified into normal and altered, also did not show statistical differences between both groups. Multiple regression analysis showed that bone mineral density of femur was directly associated with body mass index, but age was indirectly associated. The variables dark skin, parity, age at menopause, educational level and body mass index were directly associated with bone mineral density of lumbar spine, but age at menarche was inversely associated. Conclusion: these findings suggest that tubal ligation does not seem to cause an additional reduction in bone mineral density when evaluated in postmenopause.

Purpose: to analyze the pregnancy rates after laparoscopic and microsurgical treatment of hydrosalpinx. Methods: from July 1996 to May 1999 thirty-nine infertile patients with hydrosalpinx were treated according to a previously approved research protocol. They were randomly divided into two groups, according to the previously proposed surgical approach: laparoscopic or open microsurgical salpingostomy. To analyze the results, patients were stratified according to tubal damage, and pregnancy rates in both groups were determined for 24 months. Results: pregnancy rates in our series were 35.3 and 33.3% after laparoscopic and microsurgical salpingostomy, respectively. According to the severity of tubal damage, patients with mildly and moderately damaged tubes got pregnant in 66.7 and 21.7% of the cases, respectively. Cumulative pregnancy rates in one and two years were 25.0 and 34.4%, respectively. There was a single case of ectopic pregnancy, corresponding to 9.1% of all pregnancies. Conclusion: patients with mild and moderate lesions may be initially treated with surgery, and conception success is inversely proportional to the degree of tubal damage.

Purpose: to analyze the factors that may be related to insufficient material in fine needle aspiration cytology (FNAC). Patients and Methods: a total of 351 FNAC of patients with solid breast tumors were studied in a random way: 180 (51%) by Cameco's pistol holder and 171 (49%) by the auto-vacuum device. All smears were analyzed by only one cytopathologist, and they were described as malignant, suspicious, benign or insufficient for diagnosis. The significance of each variable was tested by the c² test. Results: among the 351 cases analyzed, we found 67 (19%) of insufficient material. The device used (pistol or auto-vacuum), the size of the tumor and the clinical stage of the lesions were not related to the frequency of sufficient and insufficient material. The age of the patient and the histological type of the tumor were related to the rate of insufficient material. Patients younger than 50 had a 12% rate of insufficient material, compared to 30 above 50 (p<0.03). The patients with fibroadenosis had a rate of 30%, those with ductal carcinoma, 20%, and those with fibroadenoma 12% (p<0.02). Conclusion: the present study showed a relatively high rate of insufficient material (19%), which was influenced by the age of the patient and the histological type of the biopsied breast lesion.

Purpose: to evaluate the prevalence of bacterial vaginosis (BV) in menopausal and in infertile outpatients and to analyze the current clinical diagnostic methods. Methods: we evaluated retrospectively 104 menopausal women and 86 with infertility. Characteristic vaginal discharge on gynecological examination, pH >4.5, positive KOH whiff test, and bacterial vaginosis by Gram test were considered positive. BV was established when at least 3 out of 4 criteria were found. Results: among the menopausal women, 29 patients (28.1%) were clinically positive for BV, 10 (9.6%) had positive whiff test, 68 (65.4%) vaginal pH >4.5, and 34 (32.7%) positive Gram test. For the infertile patients the figures were 20 (23.2%), 13 (15.1%), 61 (70.9%) and 26 (30.2%), respectively. According to our established criteria, BV was diagnosed in 14 menopausal (13.5%) and 15 infertile (17.4%) women. Conclusion: bacterial vaginosis prevalence was similar in both groups of patients. In addition, all diagnostic criteria should be followed in order to avoid underdiagnosing this pathology or treating an otherwise normal vaginal flora.

Purpose: to study the prevalence of congenital syphilis in a universitary hospital of the south of Brazil, emphasizing its role as a prenatal care marker. Patients and Method: a descriptive study of the congenital syphilis cases which occurred at the Hospital Geral (HG-UCS) from June 1st, 2000 to May 31st, 2001, based on the diagnosis criteria proposed by the Center for Disease Control and Prevention (CDC, 1998). Results: The prevalence of congenital syphilis was 1.5 (27 cases in 1739 births). The coefficient of congenital syphilis observed was 15.5/1000 newborns. Twenty-three pregnant women (85.2%) received prenatal care; however, the maternal infection with syphilis was diagnosed before the delivery in only 16 (69.6%) cases. Only 4 pregnant women reported an appropriate prenatal treatment of syphilis. In 8 (29.6%) cases an association of maternal syphilis with other sexually transmissible diseases was observed. The coefficient of perinatal mortality was 1.15/1000 births (two perinatal deaths). Conclusions: The authors reaffirm the importance of congenital syphilis as an indicator of perinatal health, since it is a disease that may be completely prevented by prenatal care. In addition, a high prevalence of congenital syphilis allows one to question the quality of the prenatal care, which was available to the studied group.
