PURPOSE: to evaluate the detection of high oncogenic risk human papillomavirus DNA (HPV-DNA) immediately before and 4±1.25 months after large loop excision of the transformation zone (LLETZ) in the treatment of cervical intraepithelial neoplasia (CIN). METHODS: in this clinical prospective study, 78 patients submitted to LLETZ from February to December 2001 were enrolled. All patients were submitted to colposcopic evaluation and had Pap smear and hybrid capture II (HC II) specimens collected immediately before LLETZ and four months after the procedure. Statistical analysis was made through odds ratio (OR) calculations with 95% confidence interval (95% CI). RESULTS: before excision, 67 (86%) women had positive HC II for high oncogenic risk HPV-DNA, while four months afterwards only 22 (33%) maintained positive HC II results. Positive results of HPV-DNA after treatment were not associated with previous viral load, compromised margins in the surgical specimen or age. Four months after the procedure, detection of HPV-DNA was significantly associated with cytological abnormalities (OR = 4.8; CI 95%: 1.7-13.7) but not with histological residual disease or relapse (OR = 6.0; CI 95%: 0.8-52.3). CONCLUSION: HPV-DNA detection was significantly reduced after treatment of CIN, but was not associated with the presence of histologic residual disease or relapse.

PURPOSE: tocompare the ultrasound estimation of fetal weight (EFW) with neonatal weight and to evaluate the performance of the normal EFW curve according to gestational age for the diagnosis of fetal/neonatal weight deviation and associated factors. METHODS: one hundred and eighty-six pregnant women who delivered at the institution from November 1998 to January 2000 and who had one ultra-sonographic evaluation performed until three days prior to delivery with estimation of the amniotic fluid index were included. EFW was calculated and classified in to small for gestational age (SGA), adequate for gestational age (AGA) and large for gestational age (LGA) through the normal EFW curve for this population. Neonatal weight was similarly classified. The variability of the measures and the degree of linear correlation between EFW and neonatal weight, as well as sensitivity, specificity and predictive values for the use of the normal EFW curve in the diagnosis of neonatal weight deviations were calculated. RESULTS: the difference between EFW and neonatal weight ranged from -540 to +594 g, with a mean of +46.9 g, and the two measures presented a linear correlation coefficient of 0.94. The normal EFW curve had a sensitivity of 100% and specificity of 90.5% in detecting SGA neonates and of 94.4 and 92.8%, respectively, in detecting LGA; however, the predictive positive values were low for both conditions. CONCLUSIONS:ultrasound EFW was in agreement with the neonatal weight, with a mean overweight of approximately 47 g, and its normal curve showed a good performance in the screening of SGA and LGA neonates.

Purpose: to determine the factors associated with the detection of a microinvasive carcinoma in the cervical cone of women with a previous colposcopically directed biopsy compatible with cervical intraepithelial neoplasia (CIN) 3 and to evaluate the proportion of involved margins. Patients and methods: we reviewed the medical records of 385 women (mean age: 39 years) submitted to cold conization or conization by high frequency surgery (HFS) with a loop during the period from January 1993 to July 2000. These procedures were indicated on the basis of a biopsy compatible with (CIN) 3. Results: the diagnosis of the cone was compatible with (CIN) 3 in 243 (63%) women and with (CIN) 2 in 13 (3%). Only 10 presented HPV/CIN 1 (3%) and eight had no residual disease in the cone. However, 101 (26%) women presented a microinvasive carcinoma in the cone and 10 (3%) presented a frankly invasive carcinoma. Age, menstrual status and number of deliveries were not related to the severity of the cone lesion. Women with oncologic colpocytology changes suggestive of invasion presented a significantly higher risk of having a microinvasive or invasive carcinoma as determined by final histology (p<0.01), although 52 of the 243 women with CIN 2 or CIN 3 in the cone also showed a suggestion of invasion at colpocytology. Among the women with CIN 2 or 3, the epithelium was white in 44%, dotted in 21%, and mosaic-like in 17%. This proportion was similar for women with a microinvasive or invasive carcinoma, with these images being detected in 37%, 23% and 21% of the cases, respectively. Involvement of the cone margins was significantly higher among women submitted to HFS (49%) than among those submitted to cold conization (29%). Conclusion: the absence of independent clinical and colposcopic factors associated with the detection of a microinvasive carcinoma in women submitted to conization on the basis of a biopsy compatible with (CIN) 3 justifies the conical excision of the squamocolumnar junction in high grade cervical lesions.

Purpose: the laparoscope can be used to convert an abdominal into a vaginal hysterectomy when there are contraindications for the vaginal approach, and not as a substitute for simple vaginal hysterectomy. The purpose of the present study is to discuss the role of laparoscopy in vaginal hysterectomy. Methods: between February 1995 and September 1998, 400 patients were considered candidates for vaginal hysterectomy.Exclusion criteria included uterine prolapse, adnexal tumor and uterine immobility. The Heaney technique was used, and different morcellation procedures were employed for the removal of enlarged uteri. Results: the mean age and parity was 46.9 years and 3.2 deliveries, respectively. Twenty-nine patients (7.2%) were nulliparous, and 104 (26.0%) had never delivered vaginally. Three hundred and three patients (75.7%) had a history of previous pelvic surgery, the most common being cesarean section (48.7%). The most frequent indication was leiomyoma (61.2%), and the mean uterine volume was 239.9 cm³ (30-1228 cm³). Vaginal hysterectomy was successfully performed in 396 patients (99.0%), and 73 surgeries (18.2%) were done by residents. The mean operative time was 45 min. Diagnostic/operative laparoscopy was performed in 16 patients (4.0%). Intraoperative complications included 6 cystotomies (1.5%) and one rectal laceration (0.2%). There were four conversions (1.0%) to the abdominal route. Postoperative complications occurred in 24 patients (6.0%). Two hundred and eighty-one patients (70.2%) were discharged 24 h after surgery. Conclusions: the laparoscope does not seem to be necessary in cases were the uterus is mobile and there is no adnexal tumor. The main role of the laparoscope may be to increase the awareness of gynecologists to the possibility of a simple vaginal hysterectomy in the majority of cases.
