The use of Frozen-section during surgical procedures, gives the surgeon valuable information and guides him to perform the appropriate surgical procedure. In order to determine the accuracy of Frozen-section in gynecologic surgery, we compared the results of 172 gynecologic Frozen-section diagnosis with their final diagnosis in Mirza Kockak Khan Hospital, from 1378 to 1379. A total of 106 ovarian, 43 uterine, 10 lymph node and 13 other tissue samples were obtained. The Frozen-section diagnosis was compatible with the final diagnosis in 93.6 percent of cases. The sensitivity for non benign lesions was 82.5 percent and the specificity was 96.8 percent. The positive and negative predictive values were 84 percents and 98 percent respectively. 2.3 percent of cases were falsely positive, 1.7 percent falsely negative and 1.2 percent over estimated the degree of malignancy. There was no underestimation and 1.2 percent were uncertain. Frozen-section was found to identify correctly 8 of 8 metastatic ovarian tumors and 1 of 2 germ cell tumors. The accuracy of Frozen-section was 25 percent in ovarian borderline tumors, 60 percent in ovarian mucinous and 80 percent in serous tumors. With the exception of borderline and mucinous ovarian tumors, Frozen-section diagnosis is sufficiently accurate for clinical use. Performing multiple sections is recommended in the Frozen-section diagnosis of mucinous ovarian tumors.

Background: We conducted this study To find relationship between maternal glucose challenge test (GCT) levels and fetal body weight (BW).
Materials and Methods: We analyzed five hundred women with singleton pregnancy, who had GCT at 24-28 week during pregnancy. All of them had no history of hypertension and diabetes mellitus or other medical disease before pregnancy or during previous pregnancy, and all of them had weight gain appropriate with their pre pregnancy body mass index (BMI). Also nobody had history of drug abuse or smoking. In this descriptive–analytic survey, maternal age, gravidity, BMI,GCT level ,gestational age (GA) , sex of neonate, rout of delivery , newborn weight and apgar score were evaluated .The student’s T-test and logistic regression were used for statistical analysis. We used Pearson coefficient and receiver operating characteristic (ROC) curve and chi-square test for determination GCT threshold.
Results: We found rate of small for gestational age (SGA) in newborns statistically was significant, who their maternal GCT level was ≤ 80mg/dl, P value: 0/018, specificity 89%, sensitivity 58% and confidence interval: 95% (0/162-0/545).
Conclusion: Low GCT level has association with SGA and can be used as a predictive test and may be an indication for dietary intervention.

Background: Endometrial cancer is the most common malignancy of genital system which is commonly seen after menopause. Rises in the age of marriage non-surgical methods, using systemic progestins, have been evaluated to treat the young patients with well-differentiated endometrial cancer who wish to preserve their fertility.
Methods: Twenty one infertile patients with stage Ia well-differentiated endometrial adenocarcinoma were enrolled in a quasi-experimental study. The treatment initiated with 160mg/d of megestrol acetate then continued with 320mg/d for non-responsive cases. Patients follow up with FD&C and hysteroscopy. Patients divided in two groups on the basis of response to therapy and persistent. The responsive patients were introduced to IVF group and evaluated for later fertility and birth of alive newborns for three years.
Results: This study showed a response rate of 85.71% and 14.29% undergoing TAH. The mean duration of treatment was 5.85±2.00 month. The response to therapy was observed in 27.78% with dose of 160mg/d and the remaining patients with 320mg/d. Pregnancy occurred in 27.78%, 2 of which ended up in a term delivery and the others ended before term. Recurrence happened in 16.67% that 66.67% of them experienced remission again.
Conclusion: Use of 320mg/d seems to be associated with a better therapeutic response. Serious complications were not observed with this dose. Furthermore, continuance of the drug for three month following a normal pathology report was decreased the rate of recurrence.

Background: Cervical cancer is the second most common cancer of the women worldwide. It is also an important cause of cancer-related mortality in women, after breast cancer. Nearly half million of new cases are identified yearly. The incidence rate in developing countries is greater than the developed countries. Epidemiologic studies have shown that the association of genital human papilloma virus (HPV) with cervical cancer is strong, independent of other risk factors, and consistent in several countries. The aim of this study was to determine the frequency of HPV in patients with high grade cervical intraepithelial neoplasia (CINIII, CIN II) and squamous cell carcinoma (SCC) of cervix.
Methods: Hundred specimens from patients with SCC and CINIII, CIN II, confirmed by histological review, referring to Mirza Koochak Khan Hospital from 1999-2004 were enrolled in a cross sectional study. Polymerase chain reaction was utilized for identification and typing of HPV DNA. To increase the sensitivity of HPV detection, nested PCRs were performed using MY09/MY11 as outer and GP5/GP6 as inner primers.
Results: It was possible to extract 77 of 100 specimens that HPV DNA was detected in 47 of 77 specimens. Infection with HPV was present in 32 specimens (86.5%) among SCC patients and in 15 specimens (37.5%) among CINIII, CIN II patients. The most frequent HPV types in SCC patients were HPV 16 and 18 (59.38%) and then 33 (34.38%) and in CINIII, CIN II patients was 16 (53.33%) and 18 (40%). the most frequent co-infection in both groups was HPV 16 and 18 which was present in 40.62% and 26.7% of cases respectively.
Conclusions: The most frequent HPV types in patients with SCC and CINIII, CIN II was 16 and 18 that is identical to many other countries infection pattern.
