Predictive effect of thiol/disulfide homeostasis dynamics on early pregnancy viability: A case-control study.

Objective: The main aim of this study was to investigate the differences in maternal serum thiol/disulfide homeostasis among women with abortion imminens (AI), missed abortion (MA), and healthy pregnancies during the first trimester. Materials and Methods: This was a prospective case-control study. This study was conducted on pregnant women who visited the Obstetrics Clinic at University of Health Sciences Turkey, Etlik Zübeyde Hanim Gynecology Training and Research Hospital and were diagnosed with either AI or MA during the 6th to 14th weeks of pregnancy. The participants had a normal pregnancy follow-up, no chronic illnesses, and did not take any multivitamin or antioxidant supplements except for folic acid. The study incorporated 33 pregnant women with AI, 36 with MA, and 40 with normal pregnancies. Age, and body mass index were matched across the three groups. This study used a recently developed automated spectrophotometric technique to quantify thiol/disulfide concentrations. Results: The AI group had considerably elevated levels of total thiol and native thiol (SH) compared with the MA group. Nevertheless, there was no notable disparity observed between the group of healthy pregnancies and the other two groups. Serum disulfide (SS) levels did not exhibit any significant variations among the three groups. Similarly, the ratios of SS/SH, SS/total thiol, and SH/total thiol did not show any significant differences between the groups (p>0.05). Conclusion: Patients with MA had decreased levels of total thiol and SH, which possess antioxidant capabilities, compared to the AI group. A decrease in antioxidant levels in the body may contribute to the etiology of MA. When considering our findings alongside existing literature, it remains inconclusive whether the serum thiol-disulfide ratio can predict a healthy pregnancy or MA following AI. Therefore, it is not yet seen as a promising diagnostic tool for assessing pregnancy viability. Additional investigation is required to establish the influence of dynamic thiol/disulfide homeostasis on early pregnancy loss.

Adenoid cystic carcinoma of Bartholin's gland diagnosed after lung lobectomy: Review of the literature and a case presentation.

Bartholin's gland was first identified in human female in 1675 by Caspar Bartholin. The Bartholin gland is composed of several epithelial types: The body is mucinous acini, the duct is predominantly transitional epithelium, and the orifice is the squamous epithelium. Primary carcinoma of the bartholin's gland is an uncommon neoplasm. Adenoid cystic carcinoma (ACC) of bartholin gland carcinom is a rare variant of bartholin gland carcinoma, comprising 15% of all bartholin gland malignancies. ACC of the Bartholin's gland is characterized by slow growth so recurrence and distant metastases can take a long period. So distant metastasis has been found in only a few cases to the lungs, liver, bone and brain. Here, we present the case of Bartholin's gland ACC after four years follow up and presented with a lung metastasis.

Lower serotonin level and higher rate of fibromyalgia syndrome with advancing pregnancy.

OBJECTIVE: The aim of the study is to investigate the relationship between changes in serotonin levels during pregnancy and fibromyalgia syndrome (FS) and the relationships between FS and the physical/psychological state, biochemical and hormonal parameters, which may be related to the musculoskeletal system. STUDY DESIGN: This study is a prospective case-control study conducted with 277 pregnant women at the obstetric unit of Ankara University Faculty of Medicine, in the period between January and June 2015. FS was determined based on the presence or absence of the 2010 ACR diagnostic criteria and all the volunteers were asked to answer the questionnaires as Fibromyalgia Impact Criteria (FIQ), Widespread Pain Index (WPI), Symptom Severity Scale (SS), Beck Depression Inventory and Visual Analog Scale (VAS). Biochemical and hormonal markers (glucose, TSH, T4, Ca (calcium), P (phosphate), PTH (parathyroid hormone) and serotonin levels) relating to muscle and bone metabolism were measured. RESULTS: In the presence of fibromyalgia, the physical and psychological parameters are negatively affected (p < 0.001). There was no significant difference between the fibromyalgia and control groups in terms of glucose, Ca (calcium), P (phosphorus), PTH (parathyroid hormone), TSH (thyroid stimulant hormone), fT4 (free T4) levels (p = 0.060, 0.799, 0.074, 0.104, 0.797, 0.929, respectively). A reduction in serotonin levels may contribute to the development of fibromyalgia but this was not statistically significant. The Beck Depression Inventory scale statistically showed that increasing scores also increase the risk of fibromyalgia (p <0.001). CONCLUSION: Our study has shown that serotonin levels in women with FS are lower than the control group and that serotonin levels reduce as pregnancy progresses. Anxiety and depression in pregnant women with FS are higher than the control group. The presence of depression increases the likelihood of developing FS at a statistically significant level. Serotonin impairment also increases the chance of developing FS, but this correlation has not been shown to be statistically significant.

Association of first trimester serum uric acid levels gestational diabetes mellitus development.

OBJECTIVE: To investigate the association of first trimester serum uric acid levels with the development of gestational diabetes mellitus (GDM) in low-risk pregnant women. MATERIALS AND METHODS: In this retrospective data analysis, the results of pregnant women who completed both first trimester biochemical panel and two-step GDM screening were compared with an age-, body mass index, and gestational age-matched control group. The women were grouped as either GDM or impaired glucose tolerance (IGT) according to 100-g oral glucose challenge results. Uric acid levels were compared between the groups and diagnostic utility was tested with receiver-operating characteristics curves. RESULTS: Sixty-six women in GDM group and 358 women in the IGT group were compared against 202 healthy pregnant women. The groups did not differ significantly in terms of parity, pre-gestational body mass index and gestational age. Serum samples for uric acid levels were obtained. The mean serum uric acid levels were significantly higher in the GDM and IGT groups (5.95 mg/dL (±0.97 mg/dL) and 4.76 mg/dL (±1.51 mg/dL), respectively) compared with the control group (3.76 mg/dL (±1.07 mg/dL) (p<0.001). The area under the curve for uric acid levels was 0.92 (95% confidence interval 0.88-0.95) for diagnosis of GDM. At a diagnostic threshold of 3.95 mg/dL, uric acid levels predicted development of GDM with 60% specificity and 100% sensitivity. CONCLUSION: First trimester serum uric acid has a linear association with the development of GDM and IGT.

The views of nulliparous pregnant women on the types of delivery.

OBJECTIVE: To evaluate the relevant thoughts of nulliparous pregnant women in the second trimester without an absolute indication for cesarean on delivery preferences. MATERIALS AND METHODS: This study was conducted on pregnant women who presented to the Ankara University Faculty of Medicine, Department of Obstetrics and Gynecology Pregnant Outpatients Department for antenatal follow-up between May 2014 and February 2015. A total of 237 nulliparous patients voluntarily completed the survey form and the data were evaluated using various parameters. Parameters consistent with normal distribution were evaluated using the t-test, and parameters that were not normally distributed were evaluated using the Mann-Whitney U test. Parameters with a p value <0.05 were considered significant. RESULTS: We found that 221 (93.2%) of the 237 nulliparous pregnant women preferred vaginal delivery and the remaining 16 (6.8%) preferred delivery by cesarean section. CONCLUSION: Women should be informed on the type of birth and both methods should be explained in a realistic and scientific manner in terms of benefit and risk. An effort is being made to increase vaginal birth rates worldwide and the same effort should be made in Turkey.

Placental, hepatic, and supraclavicular lymph node metastasis in pancreatic adenocarcinoma during pregnancy: A case report.

The occurrence of coexisting cancer in pregnant women is not a common phenomenon. It complicates approximately 1 in 1000 to 1500 pregnancies. We present a multiparous woman aged 27 years in her 28th week of pregnancy who was admitted to our clinic with right upper quadrant pain and was finally revealed to have multiple metastatic pancreatic adenocarcinoma. To the best of our knowledge, this is the first documented case of pancreatic adenocarcinoma to metastasize both to the placenta and multiple maternal sites (liver, supraclavicular, para-aortic lymph nodes) in a pregnant patient. Unpredictable metastases to the placenta may be encountered and may even lead to definitive diagnosis, as in our case. Therefore, the placenta in any patient with known malignancy should be sent for pathologic evaluation.
