Between 270 patients complaining of symptoms of vaginitis, bacterial vaginosis was diagnosed in 68 women (%25) based on at least three of four criteria: 1. Homogenous vaginal discharge 2. Positive amine test 3. pH more than 4.5 4. Clue cell in wet smear. The results were compared to 55 normal controls.
Clue cell with more than %20 of epithelial cells was seen in %87 of cases and %5.5 of controls. A pH more than 4.5 showed the greatest sensitivity (%100) and the smallest specificity (%47). The most frequent complaints included increased discharge, bad odor, and sensing bad odor after coitus.

Group B streptococcus (GBS) is the most important pathogen identified in bacterial cultures in neonatal sepsis, sepecially with early-onset in developed countries (approximately 1-5/1000 deliveries). Neonatal colonization with group B streptococcus results primarily from vertical transmission during the birth process. GBS carrier rate in pregnant women varies from 4.6 to 41 percent in different geographic populations. Contamination of neonates during passage through the birth canal is high (more than 50%). Of the 191 pregnant women screened in this study, 28 (14.7%) were found to be colonized with GBS, by the culture method. Direct CIE and SCA tests on SBM (Selective Broth Medium) containing mixed flora showed that only 11.5% and 18.3% had positive reaction. A total of 530 patients were studied. GBS was isolated from the blood of 4 infants (5.5%, 4 vs 73 positive cultures). Of 181 cultures of CSF only one case was positive for GBS (8.3%) and had meningitis. In another part of experiment, two false positive reactions were found using serum specimen for detection of GBS antigen by CIE. Sensitivity of CIE and SCA both were 75%, specificity, 99.3% and 98.7%. Conclusion: Although specimen collection and microbiologic methods are important factors in identification of women colonized with GBS, there is significant variation in the proportion of women colonization with GBS. This study suggests that GBS is a much less important cause of neonatal sepsis, but further studies are needed to explore these important issues.

Background and Aim: This study was conducted to evaluate the safety and efficacy of Tension-free Tape for the surgical treatment of female stress urinary incontinence.

Materials and Methods: In a prospective open study for pre and post operative, we followed 36 patients at least 1.5 years after surgery (18-28 months) all patients underwent the operation under local anesthesia, allowing the surgeon to check intra-operatively that continence has been obtained.

Results: Mean operation time was 36 minutes (range 20-45 minutes). 32(89%) of the patients was cured according to the protocol, another 3(8.3%) were significantly improved and there was 1(2.7%) failure. Mast of patients (about 91%) were operated on a one day-care basis, which implies that they were released from the hospital the day after the procedure, and no post operative catheterization, defect healing and tape rejection occurred. Pain free recovery time without any analgesic was another benefit. Five patients needed an indwelling catheter for 3 days and two uncomplicated hematoma occurred.

Conclusion: Based on the results, we conclude that Tension-free Vaginal Tape is a safe and effective ambulatory procedure for surgical treatment of genuine stress urinary incontinence, which allows the majority of the women to be discharged from the clinic the day after the procedure and start their works in the second week.

Background: Abnormal uterine bleeding (AUB) is a common presenting symptom indicative of abnormal menstrual bleeding patterns that may occur in anovulatory or ovulatory women.There are different ways to diagnose AUB, all requiring much time and energy. The purpose of this study was to evaluate and compare the value of endometrial biopsy, transvaginal ultrasonography with dilation and curettage (D&C) which is the current gold standard procedure.

Methods: A prospective-descriptive study was conducted on fifty patients referred to our center for refractory abnormal uterine bleeding who were candidates for hysterectomy. All patients underwent endometrial biopsy and transvaginal ultrasonography , followed by D&C as a Gold standard procedure in operating room just before surgery.

Results: Mean age of patients was 46.62 years. Transvaginal utrasonography offered a sensitivity of 70% and specificity of 68% demonstrating the lowest numbers compared to D&C. Endometrial biopsy had a sensitivity of 70% and specificity of 75% that was better than sonography alone.

Conclusion: D&C was the most useful and valuable procedure and addition of endometrial biopsy with transvaginal ultrasonography will not be of high value in diagnosis.

Background: Vulvovaginal candidiasis, the most common type of vaginitis, is usually caused by Candidia albicans. Patients experience a variety of symptoms. There are many types of vulvovaginal candidiasis with various microbial causes, symptoms, host circumstances, recurrence rates, and responses to treatment. The purpose of this study was to find the best method of treatment of complicated vaginitis as determined by its high prevalence, varying symptoms and signs and patient complaints.
Methods: In this open clinical trial without placebo control, we studied all patients aged 18 to 65 years, suffering from vaginitis symptoms that presented at the gynecological clinic of Arash Hospital, Tehran, Iran, during the year 2004. After obtaining informed consent, we assessed the response to a treatment of single 150 mg dose of fluconazole in one group, and sequential 150 mg doses of fluconazole in the other. The analysis was performed using SPSS statistical software (version 11). Results: With regard to symptom severity, no significant difference was found between the groups. The rate of excoriation and fissure formation demonstrated significant difference between the two groups (p=0.048). Assessment of clinical and mycological response proved that patients with severe vaginitis treated with sequential doses of fluconazole had a better general status than those in the other group. The difference between the severity of vaginitis and positive response to the treatment in culture was not significant among patients with recurrent vaginitis.
Conclusion: Patients with mild to moderate recurrent vaginitis show better response to treatment. The high rate of positive culture on day 35 reconfirms the limitation of fluconazole and other azoles as fungistatic drugs.

Background: Vaginal vault prolapse is a significant longer-term complication in patients undergoing hysterectomy. An important cause is generally acknowledged to be weakness in the uterosacral and cardinal ligaments. Vaginal delivery is known to be a risk factor, and obesity and menopause are predisposing factors. Urogynecologists are constantly looking for simple, safe and effective ways to cure vaginal apex prolapse. Infracoccygeal sacropexy, also known as posterior intravaginal slingplasty, is a useful and less-invasive procedure, with low morbidity. The aim of this study is to confirm the efficacy, safety and long-term outcome of infracoccygeal sacropexy for the treatment of vault prolapse.
Methods: In a prospective observational study, we performed infracoccygeal sacropexy to treat 26 patients who had at least grade 3 symptomatic vault prolapse secondary to transvaginal hysterectomy. Data collection included anatomic outcome, and intra- and post-operative complications.
Results: The mean patient age was 67 years. The mean operation time was 30 minutes and mean blood loss was 130 ml. No intraoperative rectal perforation was seen, and all patients were discharged within 24 hours of surgery. The symptomatic cure of prolapse rate, urgency, nocturia and pelvic pain was 96.2%, 88.8%, 92.6% and 77% orderly. Only one tape rejection occurred in one of the 26 patients.
Conclusion: Our initial experience with infracoccygeal sacropexy shows an efficacy similar to other more established surgical techniques for the cure of vault prolapse, but with less surgical morbidity. Therefore, the procedure is found to be efficient and safe, with shorter operation times, reduced postoperative complication and shorter hospital convalescence.

Background: Post-menopausal hemorrhage is one of the most common complains in gynecologic clinics. More than 60% of these cases have abnormal findings in diagnostic work ups. There is contraversy about the best diagnostic method for evaluating post-menopausal hemorrhage. The aim of this study was to evaluate the results of Trans-Vaginal Ultrasonography and compare its result to ones derived from direct endometrial biopsy and Hysteroscopy findings.

Methods: In a cross-sectional study, menopausal women who attended the outpatient clinic of Arash Hospital, Tehran University of medical Sciences, from April 2005 to March 2006 with the complain of hemorrhage were evaluated. In all of these patients, after getting informed consent, Trans-Vaginal Ultrasonography, Dilatation and Curettage and Hysteroscopy were performed.

Results: The total number of 90 women was recruited to the study with the age range of 41-80 years. The mean age of participants was 53.84 ± 6 years and 4.3 ± 5.1 years had passed from their menopause. The mean thickness of endometrium, measured by Trans Vaginal ultrasonography was 6.25 ± 3.7 millimeter. In the biopsy derived specimens, the most finding pathological presentation was atrophy (48.9%) and the Proliferative endometrium had the second prevalence (36.7%). Atrophy (44.4%) and Proliferative endometrium (33.3%) were the most prevalent finding in Hysteroscopy. There was a significant difference in endometrial thickness between groups of different pathological findings. A significant difference in endometrial thickness was also seen between groups with different Hysteroscopic finding. By grouping the data according to endometrial thickness, it became evident that endometrial thickness can predict the outcome of endometrial biopsy and Hysteroscopic finding efficiently. We used ROC curves to find the best grouping threshold for endometrial thickness to achieve the best sensitivity and specificity.

Conclusion: Measuring the endometrial thickness by Trans-Vaginal Ultrasonography is an appropriate non-invasive test for screening post-menopausal hemorrhage.

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.

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Vulvovaginal candidiasis is a fungal disease with itching, and vaginal thick white discharge. Most of non-albicans species have less sensitivity to azoles. So, definition of candida species which lead to vulvovaginal candidiasis is very important to perfect usage of drugs. In the present study 191 Candida isolates from 175 patients who admitted in Gynecology department of Mahdieh Hospital during the period 1385-1387 were identified by multiplex PCR.
Methods: One hundred seventy five vaginal swab specimens from patients were cultured on Sabouraud Dextrose Agar (SDA). The internal transcribed spacer 1 (ITS1) region between the 18S and 5.8S rRNA genes and a specific DNA fragment within the ITS2 region of Candida albicans were amplified and the multiplex PCR products were separated by electrophoresis in 2% agarose gel (200 mA, 140V), visualized by staining with ethidium bromide, and photographed.
Results: One hundred ninety one Candida isolates were identified in vaginal swab specimens from 175 patients. In 89.7% of cases, single candida species and in 10.3% cases, multiple candida species were isolated. C. albicans (65.1%), C. glabrata (13.1%), C. tropicalis (6.2%), C. krusei (4%), C. guilliermondii (0.6%), C. parapsilosis (0.6%), C. glabrata and C. albicans (5.7%), C. albicans and C. parapsilosis (1.1%), C. glabrata and C. tropicalis (0.6%), C. krusei and C. tropicalis (0.6%), C. albicans and C. tropicalis (0.6%), C. krusei and C. albicans (0.6%), C. glabrata and C. krusei (0.6%), and C. glabrata and C. krusei and C. albicans (0.6%) were the cause of disease.
Conclusion: Our findings suggest that, the common cause of both recurrent and non-recurrent vulvovaginal candidiasis was C. albicans, and then C. glabrata. Also the most common mixtures of Candida species were combination of them

Background: Intravaginal misoprostol has been shown to be an effective agent forcervical ripening and induction of labor. The aim of present study was to assess the effects of adding hyoscine to vaginal misoprostol on its success rate. Methods: In a clinical trial, 74 women who were referred to undergo legal induction of labor during first pregnancy trimester in Arash Hospital, in Tehran, Iran, between March 2006 and March 2007 were enrolled, and were randomly divided in to two groups of misoprostol (400 μg/4h, vaginal) (n=37) or misoprostol (400 μg/4h, vaginal) plus hyoscine (20 mg IV) (n=37). Their complications including nausea, vomiting, fever, abdominal pain, need for analgesics, diarrhea, vaginal bleeding, decline in hemoglobin more than 3 g/dl, need for blood transfusion and failure of treatment according to the failure of induction of labor or cervical opening in 24 hours after starting treatment and the total duration of hospitalization were compared between groups. Results: There were no significant differences between groups regarding the rate of side effects like nausea, abdominal pain and vaginal bleeding. In misoprostol plus hyoscine group, the success rate in abortion was significantly higher (40.5% vs. 18.9%, p=0.04) and total duration of hospitalization were significantly lower (1.16±0.41 vs. 1.42±0.45 days, p=0.01). There was no case of fever, need for blood transfusion or significant vaginal bleeding in both groups. Conclusions: Adding 20 mg hyoscine via IV rout to vaginal misoprostol will raise the success rate in induction of abortion, and decreases the total duration of hospitalization without adding adverse effects.

Background: Normal vaginal delivery is the best method of delivery. Vaginal delivery is followed by the best pregnancy outcomes. Reducing the rate of cesarean delivery has been a health goal for the United States with economic and social advantages. This study has been conducted with aim of maternal and neonatal outcomes of Normal Vaginal Delivery (NVD) and comparing with cesarean delivery. Methods: This descriptive- analytic study was conducted in Ghaem University Hospital in Mashhad during years 2007 until 2013. Five hundred thirty six full term infants aged 3- 14 day, born either by NVD as control group or cesarean delivery as case group par-ticipated in this study. Sampling was a convenient method. The data in questionnaire containing maternal information (maternal age, mode of delivery, maternal weight, du-ration of delivery, duration of maternal hospitalization, let down reflex, breast feeding status) and neonatal information (age, sex, Apgar score, urination frequency and defe-cation frequency) were collected by a researcher. Results: According to the findings of this study, the infant’s age (P=0.425), admission weight (P=0.278), jaundice access (P=0.162), urination frequency (P=0.165), maternal weight (P=0.869) showed no statistically significant difference between two delivery methods. Time of the first breast feeding after childbirth (P=0.000), defecation fre-quency (P=0.000), maternal age (P=0.000), maternal parity (P=0.003), duration of de-livery (P=0.000), duration of maternal hospitalization (P=0.025), feeding position (P=0.029), let down reflex (P=0.012), mastitis (P=0.025) and breast problems (P=0.027) showed statistically significant difference between the groups. It means defecation frequency, duration of maternal hospitalization, Apgar score, mastitis and breast problems were more in cesarean group, but early breast feeding after delivery, duration of delivery, proper breastfeeding position and let down reflex were more in NVD group. Conclusion: The results of this study showed in comparison with cesarean delivery, normal vaginal delivery provides better outcomes in terms of breast problems, breast feeding status, duration of labor and duration of maternal hospitalization for both mother and infant. So, adopting careful instructions in management and administration of deliveries will help the prevalence of making decisions for normal vaginal delivery and the recovery of delivery outcomes.

Background: A variety of endocrine disorders can complicate pregnancy. Diabetes insipidus although uncommon, may have devastating effect on pregnancy outcome, if unrecognized and untreated. The etiology of diabetes insipidus is often unknown, many cases are likely autoimmune, with lymphocytic infiltration of the posterior pituitary gland. Massive polyuria, caused by failure of the renal tubular concentrating mechanism, and dilute urine, with a specific gravity 1.005, are characteristic of diabetes insipidus. The diagnosis of diabetes insipidus relies on the finding of continued polyuria and relative urinary hyposmolarity when water is restricted. Most women require increased doses Desmopressin Acetate during pregnancy because of an increased metabolic clearance rate stimulated by placental Vasopressinase. By this same mechanism, subclinical diabetes insipidus may become symptomatic during pregnancy. Transient diabetes insipidus is associated with acute fatty liver and HELLP syndrome as well as twin gestation. Increased placental Vasopressinase activity, along with insufficient liver degradation in HELLP syndrome and acute fatty liver, may unmask this condition. Diabetes insipidus in pregnancy is rare. The disease results from inadequate or absent antidiuretic hormone (vasopressin) production by the posterior pituitary gland. The increased glomerular filtration rate seen in pregnancy may increase the requirement for antidiuretic hormone. Case presentation: We present a 39 years old woman, gravida3 para3, was admitted to Akbarabadi Teaching Hospital in september 2013. She was admitted due to polyuria, malaise, thirst with slight fever, six days after normal vaginal delivery. The urine volume was 8 lit/day and the specific gravity (S.G.) of the urine was 1.010. The urine osmolarity was lower than the plasma osmolarity. Electrolyte serum examination showed hypernatremia. The patient received 5 µg/day of synthetic vasopressin, in the form of l- deamino-8-Darginine vasopressin (DDAVP). This drug was given as intranasal spray in doses 0.25 mg twice daily. Plasma electrolytes and fluid status monitored carefully with initiation of therapy. DDAVP was used because it was not degraded by vasopressinase. Treatment was continuing, when the symptoms of central diabetes insipidus resolve and urinary concentrating ability was preferred. Maximum urinary osmolality over the next 11 hours was assessed, 730 mosm/kg was considered normal. Conclusion: Close attention to electrolyte and fluid balance is important in the postpartum period. The symptoms of transient vasopressin-resistant diabetes insipidus resolve in few days to a few weeks after vaginal delivery or when hepatic function returns to normal.

Background: The most common symptom of patients with gestational trophoblastic neoplasia is abnormal vaginal bleeding. Despite repeated visits of patients with postpartum choriocarcinoma and abnormal postpartum hemorrhage, delayed diagnosis leads to advanced disease with widespread metastasis. Therefore, occurrence of choriocarcinoma with variable patterns in different diagnosis of late onset postpartum hemorrhage should be considered. Early diagnosis of choriocarcinoma after term pregnancy is important that resulted in decrease of maternal morbidity. Therefor late onset postpartum hemorrhage should have an awareness. The aim of this study was to report a case of choriocarcinoma after caesarian section. Case Presentation: A 33-years-old woman one month after antecedent caesarian section in her second pregnancy admitted with abnormal vaginal bleeding. Based on raised titer concentration of β-hCG was 187000 u, with clinical suspicious of choriocarcinoma she was referred to oncology department of Ghaem Hospital, Mashhad University of Medical Sciences, Iran, in 2016. Vaginal exam revealed an enlarged uterus about 10 weeks of pregnancy. Transvaginal sonography showed an intracavitary heterogeneous mass with irregular surface in fundus without myometrium invasion. Extra pelvic metastasis excluded via vaginal exam, pulmonary X-ray and, ultrasonography and computed tomography scan. Due to early stage of gestational trophoblastic neoplasia and diagnosis of this condition, single agent chemotherapy (methotrexate) was recommended, but because of unresponsive disease, subsequently, she was treated with combination chemotherapy (etoposide, methotrexate, and actinomycin, followed by cyclophosphamide and vincristine) that led to remarkable response. After three courses of therapy, normal level of β-hCG was observed and now the patient is free of disease and under-serial follow-up visit for choriocarcinoma. Conclusion: Diagnosis of choriocarcinoma should be considered in any postpartum woman with abnormal vaginal bleeding.

Background: Lochia is the slight vaginal bleeding between 24 hour to 12 week after delivery. There isn't any standard definition for difference between normal and abnormal lochia in post-partum period. The aim of this study was to determine the relationship between ultrasonic findings of the postpartum uterus after normal vaginal delivery with the duration of lochia discharge.

Methods: In this cross-sectional study was done in Imam Khomeini Hospital, Tehran University of Medical Sciences, Tehran, Iran, from 2014 to 2015. In this study 160 women with non-complicated vaginal delivery were entered. Inclusion criteria were: Term pregnancy with gestational age > 37, singleton fetus with cephalic presentation. Exclusion criteria were pre-term pregnancies, previous Cesarean section or other uterine surgeries and twin fetuses. Transvaginal ultrasound was done in first 48 hours after delivery, endometrial thickness echogenicity and uterine size was evaluated. Maternal age, parity, duration of labor and neonatal weight were evaluated. Then the mothers were followed for 6 weeks. The quality and the quantity of lochia discharge were asked by the phone.

Results: Lochial discharge last more than 6 weeks in 96 out of 160 (60%). One had less than 4 weeks. The uterus length, thickness, height and endometrial length did not show any relationship with the duration of lochial discharge, but endometrial strip thickness significantly correlated with the duration of lochial discharge period (P=0.04). None of clinical variables like the number of gravidity, parity, live birth or child birth weight, were correlated to the duration of lochia discharge period, but the labor time was correlated to the duration of lochia discharge period (P=0.04). Although both endometrial thickness and labor time in univariate analysis were correlated to the lochia duration time but this was true just for endometrial thickness in multivariate analysis.

Conclusion: The endometrial thickness in first 48 hours after normal vaginal delivery could predict the duration of lochia discharge, there wasn’t any correlation between lochia discharge period and other ultrasound parameters.

Results: In these study 198 samples collected from patients with symptoms of vulvovaginal candidiasis, 77 vulvovaginal candidiasis cases were identified. Candida species are common in primary and recurrent cases in terms of frequency, Candida albicans (85.7%), Candida krusei (10.2%) and Candida glabrata (4.1%) were identified respectively. Total of 27 cases of recurrent vulvovaginal candidiasis, 10 cases were resistant to both clotrimazole and fluconazole (37%) was observed that the most common species are resistant to treatment were Candida albicans by (82.1%), Candida krusei (14.3%) and Candida glabrata (3.6%) respectively. Drug resistance in Candida albicans, Candida krusei and Candida glabrata causing recurrent vulvovaginal candidiasis included 69.1%, 75% and 100% respectively. Conclusion: Our findings have shown frequency of resistant non-albicans Candida species to fluconazole and clotrimazole is increasing. There is a considerable difference between Candida albicans and non-albicans species, Candida glabrata for the resistance to fluconazole and clotrimazole.
