Use of progestogens in pregnant and infertile patients

Progesterone is an essential hormone in the occurence and maintenance of pregnancy. Natural or synthetic progestogens are commonly used in pregnant patients or patients undergoing infertility treatments for various indications. Most frequently put indications for the use of progestogens in these patient populations are the prevention of spontaneous preterm birth, the prevention of pregnancy loss in pregnancies with an unexplained recurrent pregnancy loss and in patients with threatened abortion. It is also used in pregnant women undergoing nonobstetric surgery, for infertility or recurrent pregnancy loss that is thought to be due to luteal phase defect or as a luteal support in stimulated IVF cycles. We aimed to review the current evidence for the use of progestogens in each of these settings.

Relationship of maternal serum resistin and visfatin levels with gestational diabetes mellitus

Abstract Introduction: Adiponectin, resistin and visfatin are thought to play role in the pathophysiology of gestational diabetes (GDM). In this study, we aimed to investigate the association of maternal second trimester serum resistin and visfatin levels with GDM. Materials and methods: Screening and diagnosis for GDM was performed between the 24–28th gestational weeks. About 40 women diagnosed with GDM and 40 non-diabetic women constituted the study and control groups, respectively. Groups were compared for second trimester maternal serum resistin, visfatin and HbA1c levels, HOMA-IR and postpartum 75 g OGTT results. Results: Mean serum resistin (p = 0.071) and visfatin (p = 0.194) levels were similar between the groups. However, mean BMI (p = 0.013), HOMA-IR (p = 0.019), HbA1c (p < 0.0001) and birth weight (p = 0.037) were significantly higher in GDM group compared to controls. Type 2 diabetes and impaired glucose tolerance were detected in 2 (5%) and 7 (20%) women in the GDM group, respectively, with 75 g OGTT performed at the postpartum 6th week. Resistin levels of patients with GDM and postpartum glucose intolerance were higher than those with GDM but no postpartum glucose intolerance (p = 0.012). Visfatin levels in the GDM group showed a positive correlation with biparietal diameter, head circumference, abdominal circumference and femur length (p < 0.05). Conclusion: Maternal serum resistin and visfatin levels are unchanged in GDM. In patients with GDM, second trimester resistin levels may be predictive for postpartum glucose intolerance and second trimester visfatin levels may be related with fetal biometric measurements. Further larger studies are needed.

Alterations in placental pendrin expression in pre-eclampsia.

Abstract Introduction: Pendrin is an integral membrane protein and plays a key role in extracellular fluid volume and blood pressure control. We aimed to investigate the relationship between pendrin immunostaining intensity in normal and pre-eclamptic placental tissue. Methods: Fifty-six placental tissues, of which 26 were in pre-eclamptic, and 30 were in control group were evaluated by immunohistochemical staining. Positive immunostaining was evaluated using a semiquantitative score: 0, negative; +, mild; ++, moderate; and +++, intense. Results: There was more positive immunstaining in the pre-eclamptic placenta compared to the controls (p < 0.001). A significant positive correlation was observed between immunostaining level and diastolic blood pressure (r = 0.533, p = 0.005) in the pre-eclamptic group. However, no significant correlation was observed between any condition and immunostaining level in the control group. Conclusions: Placentas in the pre-eclamptic group were significantly more immunostained with pendrin than were those in the control group. In addition, a positive correlation between immunostaining intensity with pendrin and both systolic and diastolic blood pressure were observed. Pendrin may play a role in the mechanism of severe hypertension in women with pre-eclampsia.

Üçüncü basamak bir hastanedeki gebe ve/veya jinekolojik hastalıklı kadınlarda HBsAg, anti-HCV ve anti-HIV sıklığı

Objective: Hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) are viruses that can be transmitted to the health care workers by infected body fluids and from mother to the baby before, during or after delivery. In the present study, we aimed to investigate the frequency of hepatitis B surface antigens (HBsAg), hepatitis C antibodies (anti-HCV), and HIV antibodies (anti-HIV) in pregnant women and/or patients with gynecologic diseases that admit to a university hospital in Bolu. Methods: HBsAg, anti-HCV, and anti-HIV results of the pregnant women and/or patients with gynecologic diseases that admitted to the obstetrics and gynecology clinics between January 2006 and June 2012 were retrospectively investigated. All markers were tested in the microbiology laboratory of our hospital by using macro ELISA method (Axsyme and Architect i2000SR systems, Abbott Diagnostics, Chicago, IL, USA). Results: The frequency of HBsAg, anti-HCV, and antiHIV positivity were 1.8%, 0.5%, and 0% in pregnant women and 1.9%, 1.1%, and 0% in patients with gynecologic diseases, respectively. Conclusion: The frequencies detected in our hospital are at low levels as seen in developed countries. Since there is no effective method of prevention especially from HCV, awareness of this serologic result before high risk procedures will enable the doctors and the health care workers to take extensive measures to prevent the transmission of the disease.

Frequency of MEFV mutation and genotype–phenotype correlation in cases with dysmenorrhea

We aimed to investigate the relation between mutations and polymorphisms playing roles in the onset of clinical findings of Familial Mediterranean Fever (FMF) and clinical phenotypic reflections manifesting with painful episodes, such as dysmenorrhea.

Forearm compartment syndrome owing to being stuck in the birth canal: a case report

Neonatal compartment syndrome is a rare condition mainly involving the upper extremity associated with necrotic lesions. It is often initially misdiagnosed because the skin lesions mimic several other conditions of the newborn. Early diagnosis and timely intervention are of paramount importance to achieve the best outcome. In the present case, we describe a newborn with forearm compartment syndrome owing to being stuck in the birth canal.

Bicuspid aortic valve and severe aortic stenosis in a newborn exposed to carbamazapine during pregnancy

The use of antiepileptic drugs increases the risk of major congenital malformations during pregnancy. Here, we report an infant who had a history of in-utero carbamazepine exposure and who was born with a cardiac malformation. The infant was born at 39 weeks of gestation vaginally to an epileptic mother who had been treated with carbamazepine throughout her pregnancy. He was referred due to cardiac murmur in the second week of his life. The mother had not received folic acid supplementation. Transthoracic echocardiography revealed bicuspid aortic valve, mild aortic stenosis, patent ductus arteriosus, patent foramen ovale and the renal ultrasound revealed mild left hydronephrosis. Follow-up echocardiography performed 14 weeks later showed increased severity of aortic stenosis and percutaneous balloon aortic valvuloplasty was performed. To our knowledge, there is only one case report in the literature mentioning the association of a bicuspid aortic valve and aortic stenosis with oxcarbazepine exposure, which is a structural derivative of carbamazepine. However, there are no reports for association with carbamazepine itself. Bicuspid aorta and aortic stenosis may be among the cardiac malformations that result from the teratogenic effect of carbamazepine.

Intraperitoneal Nigella sativa for Prevention of Postoperative Intra-Abdominal Adhesions in Rats

ABSTRACT Objective: To evaluate intraperitoneal administration of Nigella sativa (NS) to prevent postoperative intraperitoneal adhesion (PPA) after surgical manipulation of rat uterine horn. Materials and Methods: Two forms of NS were used in the study (Volatile oil (NSVO) and the ethanolic extract (NSEE)). A total of 50 rats were randomly assigned to the sham group (n = 10), control group (n = 10), NSVO group (n = 10), NSEE group (n = 10), and the Seprafilm group(n = 10). After 14 days, rats were sacrificed. Adhesions were examined macroscopically, and degree of adhesions was scored. A part of horn was excised, and superoxide dismutase (SOD) and glutathione peroxidase activities as well as malondialdehyde levels were evaluated, and histological score was calculated. Results: Total microscopic score of the NSEE group was significantly lower than the control group (p = .001) and was marginally significantly lower than the seprafilm group (p = .005). Collagen formation score was higher in the seprafilm group compared to the sham and NSEE groups (p < 0.001, p = .003, respectively). Apoptotic cells were lower in the NSEE group compared to the control group (p = .003) and also lower in the NSEE and NSVO groups compared to the seprafilm group (p = .001, p < .001, respectively). Only SOD activity was higher in the NSVO and seprafilm groups compared to the control group (p < .001). Conclusion: NSEE form seems to have a possible effect in the prevention of PPAs. This may occur by its effect in decreasing collagen formation and by decreasing apoptosis in the injured tissues. NSVO form seems to induce SOD. Therefore, combined use of NSVO with seprafilm may increase the adhesion preventive effect of seprafilm.
