The growth and developmental status of 252 children with low birth weight (<2500 gr) born from 1988 to 1989 as cases were compared with 312 children with normal birth weight (>2500 gr) at the fifth birthday. The results of comparing these two groups of children show that: 1) In relation to weight for age of survivors, with increasing of age, weight gaining is higher in the control group in comparison with the case group (P=0.00). 2) In relation to height for age the study revealed, that this indicator differs in two groups but the difference is not significant. 3) In regard to Gomez classification: The percentages of all grades of malnutrition (mild, moderate, severe) is grater in the case group than controls. 4) By considering the developmental criteria (skipping, drawing triangle from copy, naming 5 colors, repeating sentences of 10 syllables, counting of 10 coins correctly and respectively): The study showed that developmental indicator of the case group differs from controls. The test statistic "t" showed, there is a significant difference between two variables (P=0.005). 5) By using the Riven test for evaluation of IQ, our findings characterized that, the IQ mean of the LBW and NBW are not truely different.

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.

Radioiodine therapy is the safest, simplest, least expensive and most effective method for treatment of Graves' disease. Due to difficulties in previous methods for dose determination, fixed dose method of 1-131 is now considered the best practical method for 1-131 therapy in Graves' disease, but there is no consensus on the dose. We compared two routinely recommended fixed doses of 5 and 10 mCi for this purpose.
Materials and Methods In this clinical trial, 59 patients with Graves' disease referred for radioiodine therapy were randomized into two groups, one group was treated with 5 mCi of 1-131 and the other with 10 mCi. All patients were followed for two years, with 6-month intervals.
Results: Totally, among 59 patients treated with 1-131, 20 (33.9%) patients became euthyroid and 19(32.2%) became hypothyroid, while failed therapy (no response or relapse) was noticed in 20 patients (33.9%). In the group treated by 5 mCi (33 patients), 10(30.3%) were euthyroid, 6(18.2%) were hypothyroid (overall cure of ^8.5%), while 17(51.5%) remained hyperthyroid by the end of the follow-up period. From the 26 patients treated with 10 mCi, the euthyroid and hypothyroid states were observed in 10(38.5%) and 13(50%)patients, respectively (overall cure rate of 88.5%), and hyperthyroid state in 3(11.5%). No relationship was noted between the outcome and age, sex, size of the thyroid gland and thyroid uptake, but the relationship between the disease outcome and the amount of administered radioiodine was significant (P<0.003). Although the incidence rate of early hypothyroidism (by the end of 2 years) in the group treated with 5 mCi is less than those treated with 10 mCi, the incidence of failed therapy is higher in the former group. In addition, it is known that long-term hypothyroidism prevalence is not significantly different by using different doses of I-131. On the other hand, if the initial dose is so little to cure, cost and time for perfect treatment, number of office visits and morbidity due to untreated hyperthyroidism are markedly increased.
Conclusion: Regarding lower rate of failed therapy with 10 mCi, and as there is no significant difference in late hypothyroidism between low doses and high doses of I-131, we concluded that 10 mci is the optimal fixed dose for treatment of Graves' disease.

Background: The purpose of this study was to evaluate the effect of treatment with radioactive iodine on the function of gonads in males and females with follicular and papillary thyroid carcinoma.

Materials and Methods: Consenting patients in the reproductive age were grouped according to the cumulative dose of received radioiodine and followed for at least 12 months. For all men, serum levels of FSH, LH, and testosterone were measured some (53 cases) were also studied by semen analysis. For women, tests for serum levels of LH, FSH, estrogen, and progesterone were performed.

Results: Overall, 246 patients (159 females, 87 males) were studied. In 87.4% of men, there was an increase in serum FSH level after radioiodine therapy, in 20.7% of whom the level remained high during follow-up period. The average serum level of FSH after each course of treatment was significantly higher than the level before treatment (p<0.01), and there was a meaningful correlation with the cumulative dose of received iodine (p<0.001). Reduced number of sperms was shown in 35.8% of male patients, among whom 73.7% also showed reduced motility. In 36.8% of the patients with reduced sperm number (13.2% of the total), this finding was persistent during the follow-up period. Increased level of FSH was correlated with reduced sperm counts in all doses (p

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: To evaluate long-term outcome and satisfaction of MacIndo surgery with and without amnion graft.

Methods: This is a historical cohort study of patients who were treated with the McIndo procedure for vaginal agenesis. Participants answered a structured questionnaire to describe outcome in sexual function and satisfaction. Patient characteristics along with short and long-term endings were abstracted from the medical records.

Results: Thirty-five patients responded to the questionnaire. Average age (±SD) at surgery was 28.4 ± 3 years (range 17- 48 years). The mean number of years (±SD) since surgery was 7 years (range 2-12 years). In 15 patients (42.8%) amniotic graft were amniotic graft were used only in is patients (42.8%). There was no relation between two types of surgery (long-term outcome and satisfaction with p-values of 0.346 and 0.758 respectively).

Conclusions: Since there was not a statistical difference between these two types of McIndo methods, it is recommended to apply the procedure in which amnion is not used. This procedure (without amnion graft), is an easier method with less operation time and reduced viral (HIV…) transmission.

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.

Background: The aim of this study was to assess the efficacy and safety of a new minimally-invasive surgical procedure using trans-obturator Tape (TOT) to treat female stress urinary incontinence.

Methods: This clinical trial study was performed from 2003 to 2004 in the Gynecology Department of Imam Hospital, Vali-e-Asr, Tehran, Iran. A total of 35 women with stress urinary incontinence underwent the TOT procedure. All patients underwent pre-operative clinical examination, cough-stress test (full bladder), uroflowmetry and post-voiding residual volume assessment.

Results: The mean age of patients was 50 years, ranging from 26 to 74 years, with an average urinary stress incontinence duration of six years. The mean time of follow-up was 14 months (at 1, 6, 12 and 24 months) and the average duration of surgery was about 20 minutes. The perioperative complication rate was 9% with no vascular, nerve or bowel injuries. The rate of hemorrhagic side effects (spontaneously-absorbed hematoma and blood loss not requiring blood transfusion) was 2.9%. Post-operative urinary retention and vaginal erosion occurred in one case each the former was treated by intermittent self-catheterization. In total, 91.4% of patients were completely cured and 8.6% were improved without failure of treatment.

Conclusions: The present study confirms the results obtained by Delorme and coworkers, and allows us to consider TOT as a safe, minimally invasive and efficient short-term surgical technique for the treatment of female stress urinary incontinence, alone or in combination with prolapse repair. Following this study, a randomized control trial is recommended to compare TOT with the gold standard surgery for women with urinary incontinence.

Background: Neural Tube Defect (NTD) characterized by failure of neural tube to close properly be the second most common born defect after congenital heart disease. The most prevalent forms of NTD are Anencephaly and Spinal-bifida. Many factors are involved in this anomaly. New researches suggest environmental factors like radiation, hyperthermia, Vitamin A and acid folic deficiency, anti epileptic drug like Carbamazepine, Phenobarbital, phenytoin, Folic acid antagonist like Sulfasalazine, Triametherine and systemic disease like diabet mellitus, obesity, genetic factors, the most schance 40 to 70 percentages.
Methods: In this survey cross sectional study was conducted in five hospitals depend to Tehran university during three years. Study subject identified through review of admission and discharge at major hospital through regular contact with newborn nurseries and birth hospital.
Results: In 38473 reported cases, 143 cases have neural tube defect. Among NTD cases, 11.9% of mothers had medical diseases in their previous history such as diabetes mellitus, epilepsy-psychiatric, and disorder-heart diseases. In this study group, 5.6% have preclampsia during pregnancy period. The most common NTD anomaly in this study was anencephaly and meningomyelocele that was different from studies in literature.
Conclusion: NTD result from failure of neural tube close threats fetus health up to 28 days after conception. When is often prior to the recognition of pregnancy since many pregnancy are unplanned NTD prevention is best achieve by adequate daily folic acid intake thought of reproductive ages .educational effort to promote daily intake of folic acid supplemental by women of reproductive age and NTD risk factor should be done. Early diagnostic procedure for high risk pregnancy advised.

Background: The postmortem diagnosis of early myocardial infarction is a perplexing affair in forensic pathology. The routine evaluations of autopsied hearts including macroscopic examination and study of H&E stained sections are often not contributory. Some other methods like electron microscopy need sophisticated equipments which are not available in all pathology laboratories.

Methods: In an attempt to find a more reliable and less labor- intensive method, we have studied the diagnostic value of cardiac troponin- T by an optimized immunohistochemical method on 67 autopsied hearts in Legal Medicine Organization of Iran. The cases were divided into three groups: the positive group composed of cases with the definite diagnosis of myocardial infarction (MI) as the cause of death the non-cardiac death group and finally the suspicious group which consisted of cases with high probability of early myocardial infarction, however without definite evidence of MI on the routine histopathologic studies. In stained sections, the degree of troponin T depletion was scored.

Results: With our proposed cut off, this test showed positive results in 19 out of 22 cases in MI group (86.4%), none of the 17 cases of non-cardiac death (100% specificity), and 15 out of 28 cases of suspicious group (53.6%).

Conclusions: This relatively easy method may increase the sensitivity of routine histopathologic methods in postmortem detection of early myocardial infarction. Additionally, this method does not require a particular preparation and can be done very easily on the archival paraffin blocks available in pathology departments whenever further evaluation is deemed necessary by the pathologist.

Background: The papanicolaou (pap) smear has been used to screen cervical cancer since 1940. Recently, a number of new technologies have been developed to improve the detection of cervical cancer and its precursors. However, there is substantial controversy about whether the new tests offer meaningful advantages over the conventional pap smear. Ideally, these new tests will increase the early detection of meaningful pap smear abnormalities, reduce the number of unsatisfactory smears and provide fewer ambiguous results.

Methods: In this prospective study the result of Liquid- based cytology smears (Liquid prep method) compared with conventional pap smears in terms of adequacy and ASC diagnosis in 289 patients in pathology department of mirza kochak khan hospital (Tehran, 2005- 2006). The smears were interpreted based on Bethesda system 2001.

Results: In conventional pap smear method, the number of occasions of unsatisfactory smear was 24(5%). In Liquid- based cytology method 66(22.8%) smears were unsatisfactory, In which difference between unsatisfactory groups were statistically significant (p<0.05), Also ASC diagnosis in conventional method 5(1.8%) as compared with Liquid- based cytology 6(2.1%), was not statistically significant (p>0.05).

Conclusions: There was no significant difference between two methods in term of ASC diagnosis but in conventional method adequacy of specimen was significantly better as compared with this Liquid- based cytology method.

Normal 0 false false false EN-GB X-NONE AR-SA MicrosoftInternetExplorer4 Background: Mood disturbances, such as anxiety, depression and psychological distress, are common among women in menopausal period. Effect of long term estrogen replacement on post menopausal  mood disturbances is curative but specifical studies has not done on the effects of vaginal hormonal therapy in mood disturbances in menopause. The aim of this study was objectives to clarify the effect extended by Hormon Replacement Therapy (HRT) in improving post menopausal mood disturbances.
Methods: In a single blinded clinical trial, the effects of a four months application of vaginal esterogen (premarin) versus placebo (n=20) in each groups were evaluated on mood status and sexual satisfaction, using the Hamilton depression score (HDS score), and self assessment of sexual function and pleasure. Four months after treatment completion (half applicator of nightly vaginal premarin or lubricant vaginally) collected and analyzed with Statistical tests.
Results: Decline of the mean HDS scores (depression score) was observed in the premarin group. The mean HDS score (depression) after vaginal premarin decreased from (14.6±4.7) to (3.4±2.3). (p≤0.001) also, The HDS score in placebo group increased from (10.6±3.1) to (11±3.3), that significant difference between two groups before and after treatment is seen. (p≤0.01). Vaginal premarin induced a greater improvement of HDS score (p≤0.006). Mean anxiety score decreased after vaginal premarin (p≤0.000), but is not significant difference in placebo group. (p=0.08). Sexual Satisfaction in Vaginal premarin group is significantly higher (p≤0.001).
Conclusions: Vaginal Estrogene directly or indirectly improved menopausal related mood and sleep disturbances, increased and sexual satisfaction.

This study is going to compare the effectiveness and complications of these two surgical methods.
Methods: In this study, 51 patients with prolapse admitted to vali-e-asr Hospital of Tehran University of medical science were evaluated during years 2001-2004. 26 patients were operated by posterior IVS method (the first group) and 25 of them had undertaken sacrocolpo-pexy (the second group). Data were primarily gathered from patients' folder and further complimentary information were achieved by two years follow-up and inviting patients to interview or exam.
Results: Eighty percent of women with abdominal sacrocolpopexy were cured compared to 96.2 percent with posterior IVS. Surgery complications was reported in one patient (4%) of second group while none of patients in first group experience this and the difference was not statistically meaningful. Short-term post surgical complications (hemorrhage-perforation fever and abdominal distention) were also negative in first group (posterior intra vaginal slingplasty) but these problems such as fever and abdominal distention were positive in 36% of second group (abdominal sacrocolpopexy) which was evidently statistically meaningful (p=0.001). Long- term post surgical complication (tape and mesh disfunction) were seen in 7.7% of first group while none of second group patients showed these complications.
Conclusion: According to shorter operating time, lower complications and efficient response to therapy in posterior IVS method, it can be an alternative in prolapse surgery it is preferred in elderly patients with medical problems.

Background: Several studies have investigated the variations in the anatomy of each segment of circle of Willis whereas a few have addressed the variations of this arterial circle as a whole. In this study the entire circle of Willis and its variations were studied in a cohort of Iranian people and compared with previous reports.
Methods: Anatomical variations of the circle of Willis in 132 brains of Iranian cadavers (102 male adults and 30 fetuses and infants) were studied. The dissection process was digitally filmed for further studies. Using computer software the external diameters of the vessels were measured and the circle variations were classified. The variations of the circle as a whole and segmental variations were compared with previous studies.
Results: Uni-and bilateral hypoplasia of posterior communicating arteries (PcoAs) constituted the most common variation in our study which was similar to previous works. Aplasia of the anterior cerebral artery (A1) and the posterior cerebral artery (P1) were not observed. In 3.3% of fetuses and infants and 3% of adult instances both right and left posterior communicating arteries were absent. There was one case of anterior communicating artery (AcoA) aplasia in adult group.
Conclusions: The anatomical variations discovered in Iranian circle of Willis in this study were not significantly different to those of more diverse populations reported in the literature. The main differences between the fetal and adult disposition are the diameter of the PcoA and the circular part of the P1.

Background: Radioactive synoviorthesis by injection of safe radioisotopes into the joints affected to chronic arthritis is accounted as a novel method to treat haemophilic arthropathy. The main goal of this therapy would be decrease in frequency of hemarthrosis and consumption of coagulation factors. In this study we assessed the effect of radioactive synoviorthesis on the frequency of hemarthrosis, factor consumption and other related parameters.

Methods: In an interventional study in Imam Khomeini Hospital in Tehran, Iran, after meeting of inclusion criteria and taking written consent, colloid 32p radiosynovectomy was performed for 56 joints with haemophilic arthropathy. After local anesthesia of injection site, one mci of 32P for large joints (knee) and 0.5 mci for small joints (ankle and elbow) was injected, respectively. Half of these doses were considered for children (age <12 years).

Results: The mean of age was 16.78 year old (Range: 2.5-36 SD: 7.46) and 98.2% of cases were male. Injected were knee 80.35%, ankle 12.5%, and elbow 7%. The mean of follow-up was 43.63 months (range: 3-102) that at the end, the result was 62% decrease in frequency of hemarthrosis (p=0.0001) and 84% decrease in factor consumption (p=0.0001). However, the involvement of other (non injected) joints during follow-up could lower the decrease of mean of total factor consumption.

Conclusions: Radioactive synoviorthesis can be a cost-effective alternative to decrease hemarthrosis and factor consumption in haemophilic arthropathy.

Background: Surgery is the most effective treatment of well-differentiated endometrial cancer. But using systemic progestins, have been evaluated to treat the young patients with well-differentiated endometrial cancer who wish to preserve their fertility. The aim of this study was the evaluation of megestrol acetate on endometrial adenocarcino-ma with regard to the receptors.

Methods: This was a quasi-experimental study. In 16 infertile patients with stage Ia well-differentiated endometrial adenocarcinoma. The treatment initiated with 160mg/d of megestrol acetate and continued with 320mg/d for non-responsive cases. All of the patients followed with FD&C and hysteroscopy. The responsive patients were referred to IVF group and they were followed for three years.

Results: Of nine patient in the first step of the study, 4 (25%) became pregnant. Eight patients underwent Total Abdominal Hysterectomy (TAH), and one was retreated conservatively. Of seven patient of second step of the study, five are under treatment at the time of closing the paper (three cases candidate for IVF and two are under 320 mg/d megestrol acetate), one patient is a candidate for hysterectomy, and one exited of study because of male infertility. All of the patients were progesterone receptor positive, and only one was estrogen receptor negative.

Conclusion: Conservative treatment of early stage well-differentiated endometrial adenocarcinoma with progestins may be used in highly selected young patients who have not completed their family. Close long- term follow up in this special group of patients is necessary. The evaluation of estrogen and progesterone receptors assay may be useful in predicting response to the treatment.

Background: Overactive bladder (OAB) is one of the most prevalent diseases of lower urinary system. OAB disease is defined by the Standardization Subcommittee of the International Continence Society as urinary urgency, with or without urge incontinence, usually with frequency and nocturia with no proven infection or other obvious pathology. Treatment with the antimuscarinic agents tolterodine and oxybutynin is the mainstay of therapy for overactive bladder. The study was undertaken to compare the efficacy and side-effects of tolterodine and oxybutynin in a number of Iranian women.

Methods: This study consisted of two trials and done in Imam Khomeini Hospital in 2009 in one trial, 50 patients with overactive bladder were randomized to 4 weeks of treatment with 2 mg of twice-daily tolterodine, and in the other to 5 mg of three times a day oxybutynin. Urodynamic investigations, Episodes of urge urinary incontinence and adverse events were also evaluated.

Results: The results showed a good association between the questionnaire and cystometry data but urodynamic studies showed significant differences in efficacy. Tow groups showed significant improvements in all Symptoms, but The results showed that the two drugs had no significant differences in efficacy.

Conclusion: The data obtained by questionnaire indicated that both drugs increased quality of life but there were no significant differences between the two in symptom cure. Dry mouth was the most common side-effect in the two groups but unlike other studies it was higher in the tolterodine group. Therefore, our study did not show any preference between oxybutynin and tolterodine.
