BACKGROUND Herlyn-Werner-Wunderlich syndrome is an urogenital malformation with uterus didelphys and obstructed hemivagina with ipsilateral renal agenesis. Most of these patients present after the onset of menstruation. We describe two cases diagnosed too late to prevent the complications. CASE The first patient presented with acute abdomen one year after the onset of menstruation and had salpingectomy due to pyosalpinx. The blind hemivagina was not recognized and she had severe endometriosis. She underwent hysterectomy 8 years later. The second patient presented with foul smelling vaginal discharge when she was 21 years old. She had a simple vaginal septum resection. SUMMARY AND CONCLUSION In the presence of uterine cavities in a regularly menstruating girl with dysmenorrhea, the presence of both kidneys should be checked. When unilateral renal agenesis and uterus didelphys coexist the first thing that we should remember is to confirm or refute the presence of a blind vagina.Background: Herlyn-Werner-Wunderlich syndrome is an urogenital malformation with uterus didelphys and obstructed hemivagina with ipsilateral renal agenesis.

The aim of this study is to determine the serum levels of visfatin in patients with polycystic ovary syndrome (PCOS) and to understand its correlations with other metabolic and hormonal parameters. Thirty-seven patients with PCOS and 30 women without concomitant disease were included in this study. Serum visfatin levels were similar in patients with PCOS and control group. Visfatin levels were higher in normal weight PCOS when compared with obese PCOS, but it did not reach statistical significance. Visfatin levels correlated negatively with fasting blood glucose, total cholesterol (TC), low-density lipoprotein (LDL) and lipoprotein-a levels in PCOS patients. CRP levels increased both in obese PCOS and in obese controls. Plasma visfatin levels had no correlation with homeostasis model assessment-insulin resistance and fasting insulin levels, but the negative correlation between plasma visfatin levels and lipoprotein-a, fasting plasma glucose, TC and LDL levels may indicate a role for visfatin in cardiovascular disease independent of insulin resistance.

Background: The aim of this study was to determine the serum visfatin levels in post-menopausal (PM) women with and without metabolic syndrome (MS) and to understand the correlation between serum visfatin levels and various other hormonal and metabolic parameters. Materials-Methods: We conducted a prospective cross-sectional study including 17 PM women with MS and a control group of 51 PM women without MS. MS was defined according to the National Cholesterol Education Program Adult Treatment Panel III. Results: Women with MS had statistically significantly higher fasting blood glucose, HDL, triglycerides, insulin, homeostasis model assessment of insulin resistance, and SHBG levels when compared to women without MS. Estradiol, high sensitivity C-reactive protein, and free testosterone levels were higher in the MS group, but there was no statistically significant difference between the two groups. Visfatin levels did not differ between the two groups. There was no correlation between serum visfatin levels and other parameters. Conclusions: There was no association between serum visfatin levels and MS in PM women.

Abstract Aim: To determine 25-hydroxyvitamin D levels and the relationship between 25-hydroxyvitamin D and metabolic disturbances including insulin resistance in women with PCOS. Materials and methods: We compared biochemical, hormonal parameters and 25-hydroxyvitamin D levels of 58 women with PCOS and 38 body mass index matched controls. Results: There was no difference in 25-hydroxyvitamin D levels of women with PCOS and the control group. Low 25-hydroxyvitamin D levels in women with PCOS were related to higher insulin levels (r = − 0.271 and p = 0.042). More than 90% of the subjects had hypovitaminosis D. The negative relationship between 25-hydroxyvitamin D levels and body mass index did not reach statistical significance. Conclusion: Low 25-hydroxyvitamin D levels were related to hyperinsulinemia in women with PCOS. Chinese abstract 目的:本研究旨在研究多囊卵巢综合征女性25-羟维生素D水平,以及25-羟维生素D与代谢紊乱,包括胰岛素抵抗之间的关系。 材料与方法:我们比较58名多囊卵巢综合征及38名身体指数匹配的对照组女性的生物化学,激素指标,以及25-羟维生素D的水平。 结果:PCOS组与对照组间25-羟维生素D水平没有明显差异。PCOS组女性中25羟维生素D水平低者,其胰岛素水平较高(r=-0.217,p=0.042)。超过90%的受试者有维生素D缺乏症。但25-羟维生素D以及体重指数之间的负相关性并没有达到明显的统计学差异。 结论:PCOS患者低25-羟维生素D水平与高胰岛素水平相关。

Objectives: Establishment of the knowledge and the need to make conscious in medicine students, nursing students and nurses due to the effective role of updating conscious of the health workers, we aimed to assess the knowledge of nurses and students of Istanbul Bilim University and affiliated hospitals about HPV and cervical cancer. Materials and methods: Because healthcare personnel illuminate and influences the public, the survey was conducted to medicine students of the first three years, nursing students and nurses. The reason of choosing the first three years of medicine students is with the begining of the gynecology courses at the 4th year of education in medical faculty, learning takes the place of awareness. Totally 743 participants were asked to survey but 603 subjects responded (81.2%) then the surveys that was not asked for the identity information were taken into consideration Results: Nurses and students of nursing had better knowledge about smear test when compared to students of medicine (first 3 years) and other healthcare person nel. Only 52% accepted to get a daughter vaccinated. The main reasons for vaccine rejection were the concerns about vaccine safety (41%), cost of the vaccine (10%) and sexual promiscuity (5%) after vaccination. Religious aspects were not considered as an obstacle. Conclusions: The awareness of HPV, cervical cancer and HPV vaccination should be increased. J Clin Exp Invest 2012; 3(3): 318-325

Hydatic cyst is an illness that appears in consequence of the cystic form of small strap-shaped worm Echinococcus granulosis. Frequently, cysts exist in the lungs and liver. Peritoneal involvement is rare, and generally occurs as a result of second inoculation from rupture of a liver-located hydatic cyst. Primary ovarian hydatic cyst is very rare. A 56-year-old female patient was admitted to Emergency Service with the complaint of stomachache and swollen abdomen. From ultrasonographic examination, a right ovarian 52 × 45-mm heterogeneous semi-solid cystic mass and right hydronephrosis were detected. As a result of the tomographic examination, the right ovarian growth was judged to be a 60 × 45-mm lobule contoured, septal, heterogeneously cystic mass (ovarian carcinoma). Depending on these indicators and with the diagnosis of ovarian carcinoma, laparotomy was planned. During the observation, a mass that compressed on the right ureter and dilatation in the right ureter were determined. The mass was approximately 6 cm long and smoothly contoured, including widespread adhesions, and also obliteration of the pouch of Douglas. The mass was excised and total abdominal hysterectomy and bilateral salpingo-oopherectomy performed. After a pathological examination, hydatid cyst was diagnosed. Although pointing at the issue of the distinctive diagnosis of pelvic and peritoneal mass, it should be realized that the existence of primary peritoneal and pelvic involvement of the hydatic cyst is generally a result of the second inoculation, and is also more common in regions in which Echinococcus granulosa is endemic and livestock production is prevalent.

We aimed to develop a new scale for evaluating risks and preventive measures for in-hospital falls of newborn infants, from admission to discharge of the expectant mother. Our study was prepared in accordance with Failure Modes and Effects Analysis criteria. The risks and preventive measures for in-hospital falls of newborns were determined. Risk Priority Numbers (RPNs) were determined by multiplication of the scores of severity, probability of occurrence, and probability of detection. Analyses showed that risks having the highest RPNs were the mother with epidural anesthesia (RPN: 350 point), holding of the baby at the moment of delivery (RPN: 240), and transportation of baby right after delivery (RPN: 240). A reduction was detected in all RPNs after the application of preventive measures. Our risk model can function as a guide for obstetric clinics that need to form strategies to prevent newborn falls.

Abstract Objective: Cervical carcinoma has been included in the preventable diseases category ever since the use of cervical cytology in routine practice. The Pap test is an efficient screening test. We aimed to compare the cervical cytology diagnosis with biopsy and smear follow up results in our institution. Material and Method: We aimed to compare the diagnosis of cytology material examined in our institution during the 2009-2012 period with their biopsy and smear follow ups. The diagnoses were compared with the follow up smears and/or cervical biopsies. Results: 13610 Pap tests were examined during September 2009-July 2012. Among these cases, there were 370 atypical squamous cells of undetermined significance (ASCUS), 29 atypical squamous cells-high grade intraepithelial lesions cannot be excluded (ASC-H), 155 low grade squamous intraepithelial lesion (LSIL), 33 high grade squamous intraepithelial lesion (HSIL), and 5 atypical glandular cell (AGC) diagnoses. The ratio of atypical squamous cell (ASCUS and ASC-H) to squamous intraepithelial lesions was 2.12. Squamous intraepithelial lesion was verified in 47 of 91 ASCUS cases. Among patients who had a cervical biopsy, 52 of 64 LSIL cases and all of the 21 HSIL cases had biopsy-proven SIL. Conclusion: Atypical squamous cell (ASC) is the most common diagnosis in abnormal cervical cytology. As it is indefinite, ASC is used as a quality assurance parameter and the aim is to decrease its use. As the ratio of epithelial cell abnormality is variable in different populations, the ASC/SIL is a more definite variable to be used for quality assurance. The efficiency in clinical use of the cervical cytology screening test is determined by biopsy verification. Our epithelial cell abnormality, ASC/SIL ratio and cytology-histology correlation values were parallel to the literature, proving that the methods are used reliably at our institution. Öz Amaç: Servikal sitolojinin rutin pratikte kullanılması ile birlikte serviks karsinomu önlenebilir hastalıklar içine girmiştir. Pap smear etkin bir tarama testidir. Bölümümüzde incelenen servikal sitoloji materyallerinin tanıları ile biyopsi ve smear takip sonuçları karşılaştırılması amaçlanmıştır. Gereç ve Yöntem: Bu çalışmada 2009-2012 yılları arasında bölümümüzde yapılan servikal sitoloji sonuçları gözden geçirilmiştir. Tanılar, kontrol smear tekrarı ve/veya biyopsi sonuçları ile karşılaştırılmıştır. Bulgular: Bölümümüzde Ekim 2009-Temmuz 2012 tarihleri arasında 13.610 adet Pap smear raporu incelenmiştir. Bu olgular içinde 370 önemi belirlenemeyen atipik skuamöz hücre (ASCUS), 29 yüksek dereceli skuamöz intraepitelyal lezyonun ekarte edilemediği atipik skuamöz hücre (ASC-H), 155 düşük dereceli skuamöz intraepitelyal lezyon (LSIL), 33 yüksek dereceli skuamöz intraepitelyal lezyon (HSIL), 5 atipik glandüler hücre (AGH) saptanmıştır. Atipik skuamöz hücrenin (ASCUS ve ASC-H tanılarının toplamı) skuamöz intraepitelyal lezyona oranı (ASC/SIL) 2,12’ dir. Biyopsi yapılan 91 adet ASCUS olgusunun 47’sinde SIL saptanmıştır. Biyopsi yapılan 64 adet olgusunun 52’sinde LSIL; 21 adet olgusunun tamamında HSIL tanısı doğrulanmıştır. Sonuç: Atipik skuamöz hücre (ASH) anormal servikal sitolojideki en sık tanıdır. Belirsizlik ifade ettiği için fazla kullanımı önlenmeye çalışılmaktadır ve kalite kontrolünde kullanılmaktadır. Farklı toplumlarda, Epitel Hücre Anomalisi (EHA) oranı değişken olabildiği için, ASH/SIL oranı kalite yönetimi açısından daha net bir veri olarak değerlendirilmektedir. Bir tarama testi olan servikal sitolojinin klinik uygulamalarda güvenilir şekilde kullanımı ise biyopsi doğrulaması ile mümkündür. Serimizde EHA yüzdesi, ASC/SIL oranı ve smear ile biyopsi arasındaki uyum sonuçları literatür ilgilerine paralel olup, merkezimizde güvenilir bir yöntem olarak kullanılmaktadır

Results: Considering all the cases, 94,4 % (n=2040) had normal cytology, 3,8 % (n=82) had LSIL and 1,8 % (n=39) had HSIL. In the cytological evaluation, 8,75% (n=189; n=115 HPV(+), n=74 HPV(-)) of the patients were diagnosed as ASCUS. The incidence of HPV positivity was 12,6% (n=272). The most common subtype was HPV type 6 (n=109, 5%) while the incidences of the other subtypes from second most common to least common were as follows; type 18 (n=63, 2,9%), type 16 (n=53, 2,4%), type 11 (n=20, 0,9%), type 45 (n=10, 0,4%), type 52 (n=10, 0,4%), type 59 (n=4, 0,18%) and type 51 (n=3, 0,14%). Among the HPV positive patients, the most common HPV subtype was type 6 (n=109, 40%), and the other subtypes were type 18 (n=63, 23,2%), type 16 (n=53, 19,5%), type 11 (n=20, 7,3%), type 45, 51, 52 and 59. Conclusions: Eighty-nine percent of the HSIL smears were positive for HPV subtype 16 and/or 18. This suggests that by the use of vaccination programs, a significant amount of precancerous cervical lesions and cancer might be prevented.

The aim of this study was to investigate the role of quadruple test parameters in predicting the risk of delivering a small for gestational age (SGA) infant. The quadruple test results of patients performed at 16–18 weeks of pregnancy were searched retrospectively. Alpha-fetoprotein (AFP) levels higher than 2 MoM were associated with a risk of delivering an SGA infant (p = 0.025), sensitivity 8%, specificity 98%, positive predictive value 25%, negative predictive value 91%. Other quadruple test parameters were not related to delivery of an SGA infant. The introduction of AFP as a screening test for the detection of SGA infants does not seem feasible, but we suggest clinicians take it into account when counselling the patients about the results of Down syndrome screening tests.
