The "Non-Treated" Versus "LT3-Treated" Protocols of Short-Term Hypothyroidism Induction in Differentiated Thyroid Cancer: An Analysis of Hypothyroid Complications, Mood Disorders, and Quality of Life.

This study aimed to compare "non-treated" versus "levotriiodothyronine (LT3)-treated" protocols of short-term hypothyroidism induction prior to radioactive iodine (RAI) ablation therapy in differentiated thyroid cancer (DTC). A total of 120 DTC patients who had thyroxine withdrawal either via 4-week hypothyroidism induction (non-treated group, n=60) or 2-week administration and then 2-week withdrawal of LT3 (LT3-treated group, n=60) to induce hypothyroid state prior to RAI ablation after initial surgery were included. Complications related to hypothyroidism-induction, Beck Depression Inventory (BDI), Hospital Anxiety-Depression Scale (HADS), and SF-36 health-related quality of life (HRQoL) scores were recorded. In the non-treated group, transition from euthyroid to hypothyroid state was associated with significant increase in the likelihood of moderate-to-severe depression on BDI (p<0.001), presence of depression on HADS-D (p<0.001), presence of anxiety on HADS-A (6.7% during euthyroid state vs. 33.3% during hypothyroid state, p<0.001), and major syndrome on BPRS (0.0 vs. 10.0%, p=0.001) as well as significant decrease in all SF-36 HRQoL domain scores (p<0.001 for each). In conclusion, our findings indicate the likelihood of L3-treatment to enable a more favorable transition period from euthyroid to hypothyroid state without experiencing a deterioration in depression, anxiety, or HRQoL.

Genetic variations in OLR1 gene associated with PCOS and atherosclerotic risk factors.

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age. The aim of this study was to investigate the association of oxidized low-density lipoprotein receptor 1 (OLR1) gene variations with the susceptibility of PCOS and to examine the relationship between the frequencies of OLR1 gene variations and atherosclerotic risk factors. Genomic DNA was extracted from blood samples collected from 49 patients with PCOS and 43 healthy controls. The variants in the OLR1 gene were identified using next-generation sequencing (NGS). Heterozygous rs11053646 (K167N), rs11611438, rs11611453, and rs35688880 genotype frequencies were significantly higher in the PCOS group than that of control group. Single nucleotide polymorphism (SNP) rs34163097 minor A allele increased the PCOS risk by ∼10-fold (p = 0.03). SNPs rs11053646, rs11611438, rs11611453, rs34163097, and rs35688880 were positively correlated with body mass index (BMI). The logistic regression model (area under the curve: 0.770, p = 0.000) further revealed a combination of 2-h plasma glucose (PG-2 h), dehydroepiandrosterone sulfate (DHEAS), and rs11053646 as predictors of PCOS phenotype. This is the first study reporting the NGS data of OLR1 gene variants which might be associated with the pathogenesis of PCOS and several atherosclerotic risk factors, particularly higher BMI and DHEAS. To fully understand the genetic basis of PCOS and the contribution of OLR1 gene variants to PCOS pathogenesis, additional large-scale studies are warranted.

Association of paraoxonase-1 L55M and Q192R polymorphisms with PCOS risk and potential risk factors for atherosclerosis.

AIM: To examine the PON1-L55M and -Q192R polymorphisms for polycystic ovary syndrome (PCOS) risk in relation with atherosclerosis risk markers. METHODS: Blood samples were collected from 203 women (PCOS [n = 151], control [n = 52]). Genomic DNA was extracted and RFLP method was performed following the amplifications of the target regions. RESULTS: Individuals with 192QR/192RR genotypes had a 2.5-fold increased risk of representing PCOS compared with the individuals with 192QQ genotype. Q192R was more strongly associated with PCOS than previously suggested atherosclerosis risk markers. Q192R status and body mass index values in combination were established to be a significant predictor of PCOS (AUC: 0.655, p = 0.001). CONCLUSION: This is one of the first studies suggesting the use of combination biomarkers to better predict the risk of developing PCOS.

Ultrasonographic evaluation of the femoral cartilage thickness in patients with hypothyroidism.

[Purpose] The aim of this study was to investigate the effects of hypothyroidism on femoral cartilage thickness by using ultrasound, which has been found to be useful in the early diagnosis of knee osteoarthritis. [Subjects and Methods] Forty patients diagnosed with hypothyroidism and 30 age-, gender-, smoking status, physical activity-, and body mass index-matched healthy subjects were enrolled. The thickness of the femoral articular cartilage was measured using a 7- to 12-MHz linear probe. Three mid-point measurements were taken from each knee at the lateral condyle, intercondylar area, and medial condyle. [Results] Age, gender, body mass index, smoking status, and physical activity were similar between the groups, but patients with hypothyroidism had thinner femoral cartilage than the healthy controls at all measurement sites. Nonetheless, the differences were not statistically significant (except in the case of the left medial condyle). [Conclusion] Ultrasonographic measurement of femoral cartilage thickness may be useful in the early diagnosis of knee osteoarthritis in patients with hypothyroidism.

Alteration of maternal serum irisin levels in gestational diabetes mellitus.

OBJECTIVES: The aim of our study was to compare serum irisin concentrations in pregnant women with and without ges-tational diabetes mellitus (GDM). MATERIAL AND METHODS: This study was performed at the Tertiary Care Center, Department of Obstetrics and Gynecol-ogy, between January 2014 and April 2014. A total of 45 pregnant women with GDM (diabetes group) and 41 BMI- and age-matched healthy pregnant women (control group) were recruited. Maternal serum irisin levels were measured by enzyme-linked immunosorbent assay kit at 24-28 weeks of gestation. An association between maternal serum irisin lev-els and metabolic parameters was analyzed. Body mass index, serum levels of glucose, insulin and irisin were tested and analyzed in the study group and controls. RESULTS: Pregnant women with GDM had significantly higher fasting plasma glucose (p = 0.001), first-hour OGTT glucose (p = 0.001), second-hour OGTT glucose (p = 0.001), and fasting insulin (p = 0.045) levels as compared to controls. Serum irisin levels were 1.04 ± 0.3 and 1.3 ± 0.2 in pregnant women with GDM and healthy pregnant controls, respectively (p = 0.001). Correlation analysis between irisin levels and anthropometric and biochemical parameters in patients with gestational diabetes revealed that none of the investigated parameters correlated with serum irisin level. CONCLUSIONS: Our results suggest that serum irisin levels might be introduced as a novel marker for GDM, with decreased levels of irisin being indicative of GDM.

Nesfatin-1 and Vitamin D levels may be associated with systolic and diastolic blood pressure values and hearth rate in polycystic ovary syndrome.

Obesity, insulin resistance (IR), inflammation, and hyperandrogenism may lead to polycystic ovary syndrome (PCOS) and hypertension. Nesfatin-1 (N1) may be related to IR, obesity, and hypertension. Furthermore, a vitamin D (VD) deficiency is associated with hypertension and PCOS. We aimed to investigate N1 and VD levels in PCOS that have an effect on systolic and diastolic blood pressure (BP) and heart rate (HR).This study included 54 patients with PCOS and 48 age-body mass index (BMI)-matched healthy controls. PCOS was diagnosed according to clinical practice guidelines. Ferriman-Gallwey scores (FGS) were calculated, while N1, VD, and other hormonal and biochemical parameters were measured for all subjects. Systolic and diastolic BP was measured as well. HR was calculated using an electrocardiogram.The levels of N1 (p < 0.001), high-sensitivity C-reactive protein (hs-CRP) (p = 0.036), homeostasis model assessment as an index of insulin resistance (HOMA-IR) (p < 0.001), systolic (p < 0.001) and diastolic (p < 0.001) BP and HR (p < 0.001) in the PCOS group were significantly higher than in the control group. However, the VD levels of the PCOS group were lower than the control group (p = 0.004). N1 had a strong positive correlation with BMI, HOMA-IR, hs-CRP, luteinizing hormone, systolic and diastolic BP, and HR. VD levels were negatively correlated with HOMA-IR and luteinizing hormone.Elevated N1 and decreased VD levels may be related to the presence of high-normal BP or hypertension in PCOS subjects.  N1 level may be associated with an increased BP due to its relation to inflammation and IR.

EVALUATION OF PARA- AND PERIRENAL FAT THICKNESS AND ITS ASSOCIATION WITH METABOLIC DISORDERS IN POLYCYSTIC OVARY SYNDROME.

OBJECTIVE: The aim of this study was to compare para- and perirenal fat (PFT) and subcutaneous abdominal fat (SFT) measurements between patients with polycystic ovary syndrome (PCOS) and control subjects and to assess the possible relation with metabolic disorders. METHODS: This study included 68 patients with PCOS and 40 age- and body mass index (BMI)-matched healthy controls. We evaluated anthropometric, hormonal, and metabolic parameters, and abdominal ultrasonography was performed to measure PFT and SFT. RESULTS: The mean PFT values were 6.1 ± 2.9 mm in patients with PCOS and 4.3 ± 2.3 mm in healthy controls (P = .002). SFT values were also higher in the patient group (9.6 ± 5 mm) compared to healthy subjects (3.5 ± 0.5 mm) (P = .017). A significant positive correlation was found between PFT and BMI (r = 0.368), waist circumference (WC) (r = 0.441), Ferriman-Gallwey (FG) score (r = 0.313), blood pressure (systolic, SBP, r = 0.213; diastolic, DBP, r = 0.215), plasma glucose (r = 0.195), homeostasis model assessment-insulin resistance (HOMA-IR, r = 0.273), SFT (r = 0.555). Conversely, negative correlations were found between PFT and estradiol (r = -0.218) and sex hormone-binding globulin (SHBG, r = -0.304). Nonobese PCOS patients (6.1 ± 3.07 mm) had higher PFT values than nonobese controls (3.47 ± 1.5 mm); however, SFT measurements did not differ (P = .086). In multiple linear regression analysis, SFT (P = .006) was a significant and independent predictor for PFT, along with WC (P = .023). In a stepwise model, SFT was the predictor of PFT (P = .001). CONCLUSION: PFT values were higher particularly in nonobese PCOS patients compared to nonobese control subjects. There was a significant interaction between PCOS and obesity on PFT.

Bone mineral density in geriatric patients with toxic nodular goiter.

BACKGROUND AND AIMS: We aimed to assess bone mineral density (BMD) in geriatric patients with hyperthyroidism caused by TNG. MATERIALS AND METHODS: Bone mineral density was measured at the lumbar spine and proximal femur, using dual-X-ray absorptiometry (DXA) in 90 patients with TNG (mean age; 69.2 ± 4.4 years) and compared with those in 42 age-matched healthy subjects (mean age; 68.40 ± 4.3 years). Serum levels of TSH, fT3, fT4, 25-OH vitamin D and PTH were measured. RESULTS: BMD was significantly lower at total spine (0.904 ± 0.1 vs. 1.114 ± 0.1 g/cm(2)) and total hip (0.850 ± 0.1 vs. 1.079 ± 0.1 g/cm(2)) in male patients with TNG in comparison to the healthy men (p = 0.001, p < 0.001). Postmenopausal women with TNG had lower BMD measurements at total lumbar spine (0.754 ± 0.1 vs. 0.870 ± 0.2 g/cm(2), p < 0.001) and total hip (0.765 ± 0.1 vs. 0.831 ± 0.2 g/cm(2), p < 0.001) in comparison to the healthy women. T scores of total lumbar spine and hip were lower in patients with subclinical hyperthyroidism compared to the control group, respectively (-1.9 ± 1.7 vs -0.8 ± 1.8, p = 0.007; -1.09 ± 1.2 vs. -0.02 ± 1.6, p = 0.001). While serum levels of fT3 and fT4 revealed a negative correlation with T score of BMD measurements at the total spine and hip, TSH levels were positively correlated. We did not find a difference in serum calcium, phosphorus, 25-OH vitamin D and PTH levels between the two groups (p > 0.005). CONCLUSION: Geriatric patients with hyperthyroidism secondary to TNG had reduced BMD at the total spine and hip. Thus, we suggest to investigate bone mineral density in geriatric patients with TNG.

Serum macrophage migration inhibitory factor levels in Hashimoto's thyroiditis; a case control study.

OBJECTIVE: The cell-mediated immune process by CD4+ and CD8+ lymphocyte subsets of T-cells has a major role in the pathogenesis of Hashimoto's thyroiditis (HT). However, the exact mechanisms of initiation and progression of thyroid autoimmunity have not been completely clarified yet. Macrophage migration inhibitory factor (MIF) is commonly recognized as playing vital roles in various autoimmune diseases. Ee aimed to investigate serum MIF levels in subjects with HT and correlate them with the level of thyroid hormones and autoantibodies. MATERIALS AND METHODS: This study included 93 patients with untreated Hashimoto's thyroiditis and 53 healthy controls. We measured serum levels of TSH, free T4 (FT4), free T3 (FT3), anti-thyroglobulin autoantibody (TGAb) and anti-thyroid peroxidase autoantibody (TPOAb) in all patients and thyroid ultrasonography was performed. The concentration of MIF was measured using enzyme-linked immunosorbent assay (ELISA) method. RESULTS: We enrolled 93 patients with HT (mean age; 31.3 ± 11.1 years), and 53 healthy control group (mean age; 29.3 ± 8.5 years) in the current study. The patient group consisted of 52 with euthyroid autoimmune thyroiditis, 31 with subclinical hypothyroidism and 10 with overt hypothyroidism. Serum levels of MIF were higher in patients with overt hypothyroidism (6300.9 ± 2504.3 pg/ml) than the euthyroid patients (3955.2 ± 3013.6 pg/ml) (p = 0.036). CONCLUSION: MIF increases in overt hypothyroidism due to the Hashimoto's thyroiditis. Further investigations are needed to explore the role of MIF in pathogenesis of Hashimoto's thyroiditis.

Does low pentraxin-3 levels associate with polycystic ovary syndrome and obesity?

Pentraxin-3 (PTX3) a cytokine-inducible molecule is released from various tissues. Its level increases as a response to different inflammatory conditions. Polycystic Ovary Syndrome (PCOS) is considered as a proinflammatory state. The aim of this study was to investigate the association between PTX3 and various metabolic and hormonal parameters in PCOS patients. This study included 64 new diagnosed PCOS patients who had been never treated previously with PCOS and 46 healthy controls with matched age and body mass index (BMI). PTX3, biochemical and hormonal parameters of both groups were measured. The patients were divided into obese and non-obese subgroups according to BMI (above or lower than 25 kg/m²). PTX3, HOMA-IR and high sensitive C-reactive protein (hs-CRP) levels of these subgroups were compared. Serum PTX3 (p=0.013), hs-CRP (p=0.015) and HOMA-IR (p=0.023) levels of PCOS patients were significantly higher than the control group. Serum PTX3 has been found to have negative correlations with BMI (r=-0.318, p < 0.001), waist circumference (r=-0.306, p < 0.001), HOMA-IR (r=-0.324, p < 0.001) and hs-CRP (r=-0.206, p=0.031). Subgroup analysis revealed PCOS women with obesity to have significantly higher serum PTX3 level than non-obese PCOS subjects (p=0.012), non-obese controls (p=0.015) and obese controls (p=0.002). Women with new diagnosed PCOS especially obese subjects had significantly lower serum PTX3 than the control group. PTX3 has been found to be negatively correlated with BMI and insulin resistance. Low PTX3 level may have a role in the etiology of PCOS and in the formation of atherosclerotic diseases by stimulation of chronic inflammation.

The relationship between retinal nerve fiber layer thickness and carotid intima media thickness in patients with type 2 diabetes mellitus.

AIMS: The aim of the present study was to investigate retinal nerve fiber layer (RNFL) thickness in patients with type 2 diabetes mellitus (T2D) using spectral-domain optical coherence tomography and to evaluate the relationship between RNFL thickness and carotid intima media thickness (CIMT). METHODS: This study included 171 patients with T2D (53.2 ± 8.8 years) and age matched 61 healthy controls (51.9 ± 8.1 years). We evaluated anthropometric and metabolic parameters as well as RNFL and CIMT measurements in patients with T2D and controls. The Mann-Whitney U test was used to compare the continuous variables and the Chi-square test was used to compare categorical variables. Spearman's rank correlation test was used for calculation of associations between variables. RESULTS: The average RNFL thickness was 84.82 ± 11.22 µm in patients with T2D and 92.35 ± 8.45 µm in healthy controls (p<0.001). Mean CIMT values were higher in patients with T2D (0.80 ± 0.1mm) than the healthy subjects (0.72 ± 0.1mm) (p<0.001). A significant negative correlation was found between age and all quadrants of RNFL. There was a negative correlation between average RNFL thickness and HbA1c (r=-0.176), uric acid (r=-0.145), CIMT (r=-0.190) and presence of carotid plaque (r=-0.193). The superior RNFL thickness was negatively associated with HbA1c (r=-0.175), CIMT (r=-0.207) and carotid plaque (r=-0.176). There was also an inverse correlation between the inferior RNFL thickness and HbA1c (r=-0.187) and carotid plaque (r=-0.157). CONCLUSION: Thinning of RNFL might be associated with atherosclerosis in patients with T2D.

Bilirubin Level is Associated with Left Ventricular Hypertrophy Independent of Blood Pressure in Previously Untreated Hypertensive Patients.

BACKGROUND AND OBJECTIVES: Left ventricular hypertrophy (LVH), a sign of subclinical cardiovascular disease, is an important predictor of cardiovascular morbidity and mortality. The aim of our study was to determine the association of left ventricular mass (LVM) with possible causative anthropometric and biochemical parameters as well as carotid intima-media thickness (CIMT) and brachial flow-mediated dilation (FMD) as surrogates of atherosclerosis and endothelial dysfunction, respectively, in previously untreated hypertensive patients. SUBJECTS AND METHODS: Our study included 114 consecutive previously untreated hypertensive patients who underwent echocardiography and ultrasonography to evaluate their vascular status and function via brachial artery CIMT and FMD. RESULTS: Among all study parameters, age, systolic blood pressure (BP), diastolic BP, pulse pressure, plasma glucose, uric acid, total bilirubin, direct bilirubin, hemoglobin, and CIMT were positively correlated with the LVM index. Multiple logistic regression analysis revealed that office systolic BP, age, male gender, and total bilirubin were independent predictors of LVH. CONCLUSION: Bilirubin seems to be related to LVM and LVH. The positive association of bilirubin with these parameters is novel and requires further research.

Factors affecting mortality in elderly patients hospitalized for nonmalignant reasons.

Elderly population is hospitalized more frequently than young people, and they suffer from more severe diseases that are difficult to diagnose and treat. The present study aimed to investigate the factors affecting mortality in elderly patients hospitalized for nonmalignant reasons. Demographic data, reason for hospitalization, comorbidities, duration of hospital stay, and results of routine blood testing at the time of first hospitalization were obtained from the hospital records of the patients, who were over 65 years of age and hospitalized primarily for nonmalignant reasons. The mean age of 1012 patients included in the study was 77.8 ± 7.6. The most common reason for hospitalization was diabetes mellitus (18.3%). Of the patients, 90.3% had at least a single comorbidity. Whilst 927 (91.6%) of the hospitalized patients were discharged, 85 (8.4%) died. Comparison of the characteristics of the discharged and dead groups revealed that the dead group was older and had higher rates of poor general status and comorbidity. Differences were observed between the discharged and dead groups in most of the laboratory parameters. Hypoalbuminemia, hypertriglyceridemia, hypopotassemia, hypernatremia, hyperuricemia, and high TSH level were the predictors of mortality. In order to meet the health necessities of the elderly population, it is necessary to well define the patient profiles and to identify the risk factors.

A rare case of acute renal failure secondary to rhabdomyolysis probably induced by donepezil.

Introduction. Acute renal failure (ARF) develops in 33% of the patients with rhabdomyolysis. The main etiologic factors are alcoholism, trauma, exercise overexertion, and drugs. In this report we present a rare case of ARF secondary to probably donepezil-induced rhabdomyolysis. Case Presentation. An 84-year-old male patient was admitted to the emergency department with a complaint of generalized weakness and reduced consciousness for two days. He had a history of Alzheimer's disease for one year and he had taken donepezil 5 mg daily for two months. The patient's physical examination revealed apathy, loss of cooperation, and decreased muscle strength. Laboratory studies revealed the following: urea: 128 mg/dL; Creatinine 6.06 mg/dL; creatine kinase: 3613 mg/dL. Donepezil was discontinued and the patient's renal function tests improved gradually. Conclusion. Rhabdomyolysis-induced acute renal failure may develop secondary to donepezil therapy.

The relation between carotid intima media thickness and serum osteoprotegerin levels in nonalcoholic fatty liver disease.

AIM: This study was designed to evaluate carotid intima media thickness (CIMT) and serum osteoprotegerin (OPG) levels in nonalcoholic fatty liver disease (NAFLD) in comparison to healthy controls and to investigate factors predicting the CIMT increase. MATERIALS AND METHODS: A total of 60 outpatients [median (min-max) age 44.5 (24.0-65.0) years, 63.3% were females] diagnosed with NAFLD via ultrasonography performed during their admission to our hospital for any reason and 30 control subjects [median (min-max) age 39.5 (24.0-57.0) years, 73.3% were females] with normal liver echogenicity in ultrasonography were included in this study. Data on demographic characteristics, anthropometric measurements, biochemical and hematological tests, CIMT measurement, serum levels for OPG, and predictive factors for the CIMT increase were collected. RESULTS: Median (min-max) CIMT [0.60 (0.40-1.10) vs. 0.50 (0.30-0.60), P<0.001) and OPG (pg/mL) [65.0 (18.1-272.8) vs. 32.0 (10.1-82.3), P<0.001] levels were significantly higher in NAFLD patients compared to controls, while there was a significant positive correlation between CIMT and serum OPG (r=0.42, P<0.001). Mean CIMT value was determined to increase significantly by 0.001 cm (P=0.001) for each 1 pg/mL of increase in OPG levels, by 0.103 cm (P<0.001) in case of concomitant NAFLD (P<0.001), and by 0.006 cm (P<0.001) for each 1 pg/mL of increase in urea levels. CONCLUSION: Our findings indicate higher levels of serum OPG and CIMT in patients with NAFLD compared to controls along with a positive correlation between serum OPG and CIMT levels. High levels of serum OPG, presence of NAFLD, and high levels of serum urea seem to be the independent risk factors predictive for the CIMT increase.

Testosterone- and cortisol-secreting adrenocortical oncocytoma: an unusual cause of hirsutism.

Objective. Oncocytomas of the adrenal cortex are usually benign and nonfunctional. They are rarely seen as the cause of hirsutism. Therefore, we aimed to report a case of adrenocortical oncocytoma presenting with hirsutism. Methods. We report a testosterone- and cortisol-secreting adrenal oncocytoma in a 23-year-old female patient presenting with hirsutism. Results. The patient had the complaint of hirsutism for the last year. Laboratory tests revealed total testosterone level of 4.2 ng/mL, free testosterone of >100 pg/mL, and DHEAS level of 574 µg/dL. There was no suppression in cortisol levels with 2 mg dexamethasone suppression test (5.4 µg/dL). Adrenal MRI revealed a 27 × 25 mm isointense solid mass lesion in the left adrenal gland and the patient underwent laparoscopic left adrenalectomy. Pathological examination confirmed the diagnosis of benign adrenocortical oncoyctoma. Conclusion. This well-characterized case describes a testosterone- and cortisol-secreting adrenocortical oncocytoma as a possible cause of hirsutism. To our knowledge, this is the second report in the literature. Adrenal oncocytomas should always be considered in the differential diagnosis of hirsutism.

Epicardial adipose tissue thickness and NGAL levels in women with polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with an increased cardiovascular disease (CVD) risk and early atherosclerosis. Epicardial adipose tissue thickness (EATT) is clinically related to subclinical atherosclerosis. In the present study, considering the major role of neutrophil gelatinase-associated lipocalin (NGAL) which is an acute phase protein rapidly releasing upon inflammation and tissue injury, we aimed to evaluate NGAL levels and EATT in PCOS patients and assess their relationship with cardiometabolic factors. METHODS: 64 patients with PCOS and 50 age- and body mass index-matched healthy controls were included in the study. We evaluated anthropometric, hormonal and metabolic parameters. EATT was measured by echocardiography above the free wall of the right ventricle. Serum NGAL and high-sensitive C- reactive protein (hsCRP) levels were measured by ELISA. RESULTS: Mean EATT was 0,38 +/-0,16 mm in the PCOS group and 0,34 +/-0,36 mm in the control group (p = 0,144). In the obese PCOS group (n = 44) EAT was thicker compared to the obese control group (n = 41) (p = 0.026). Mean NGAL levels of the patients with PCOS were 101,98 +/-21,53 pg/ml, while mean NGAL levels were 107,40 +/-26,44 pg/ml in the control group (p = 0,228). We found a significant positive correlation between EATT and age, BMI, waist circumference, fasting insulin, HOMA-IR, triglyceride and hsCRP levels in PCOS group. CONCLUSIONS: Thickness of the epicardial adipose tissue can be used to follow the risk of CVD development in obese PCOS cases. However serum NGAL levels do not differ in patients with PCOS and control group.

Increased bladder wall thickness in diabetic and nondiabetic women with overactive bladder.

PURPOSE: Bladder wall thickness has been reported to be associated with overactive bladder (OAB) in women. Diabetic women have an increased risk for OAB syndrome and may have an increased risk for bladder wall thickness. METHODS: A total of 235 female patients aged 40 to 75 years were categorized into four groups. The first group consisted of women free of urgency or urge urinary incontinence. The second group included nondiabetic women with idiopathic OAB. The third group consisted of women with diabetes and clinical OAB, and women with diabetes but without OAB constituted the fourth group. Bladder wall thickness at the anterior wall was measured by ultrasound by the suprapubic approach with bladder filling over 250 mL. RESULTS: The diabetic (third group) and nondiabetic (second group) women with OAB had significantly greater bladder wall thickness at the anterior bladder wall than did the controls. However, the difference was not significant between the diabetic (third group) and the nondiabetic (second group) women with OAB. Women with diabetes but without OAB (fourth group) had greater bladder wall thickness than did the controls but this difference was not significant. Additionally, the difference in bladder wall thickness between diabetic women with (third group) and without (fourth group) OAB was not significant. CONCLUSIONS: This is the first study to show that bladder wall thickness is increased in diabetic women with and without OAB. Additionally, nondiabetic women with OAB had increased bladder wall thickness. Further studies may provide additional information for diabetic and nondiabetic women with OAB, in whom the etiopathogenesis of the disease may be similar.

Routine Screening for Cushing's Syndrome Is Not Required in Patients Presenting with Obesity.

Background. Cushing's syndrome (CS) is a relatively unusual condition that resembles many of the phenotypic features of obesity. Our aim was to evaluate the frequency of CS in obese patients. Materials and Methods. This study included 354 consecutive patients (87.9% female, age 37.8 ± 13.4 years) who presented with simple obesity. All the patients were evaluated for the clinical signs of CS. Lipid parameters, fasting glucose (FPG) and insulin, 75 gr oral glucose tolerance test, basal cortisol and ACTH were measured. 1 mg overnight DST was performed. Results. The mean weight of the patients was 102.4 ± 20.1 kg and BMI 40 ± 7.35 kg/m(2). 34.5% of the patients were hypertensive. 36.2% of the patients had central obesity, 72% dorsocervical fat accumulation, 28.8% abdominal striae and 23.2% acne. 49.4% of the women had hirsutism. 46.5% had prediabetes and 12.0% had type 2 diabetes, 72.6% had dyslipidemia. The mean cortisol and ACTH levels were as follows: 9.28 ± 3.53 µ g/dL and 17.02 ± 10.43 pg/mL. Seven patients failed to suppress plasma cortisol to less than 1.8 µ g/dL. Biochemical confirmation tests were performed in these patients and 2 of them were diagnosed glucocorticoid-secreting adrenal adenoma. Conclusions. Routine screening for CS in obese patients is not required.

Distribution of Thyroid Cancer in the Eastern Part of Turkey 27 Years After the Chernobyl Accident.

BACKGROUND: The Chernobyl accident caused widespread effects across Europe and huge areas where radiocontaminated. The effects of the Chernobyl accident on thyroid cancer have been investigated in most European countries. According to the data of the Turkish Atomic Energy Authority, the eastern part of the Black Sea region was the most radiocontaminated area in Turkey at the time of Chernobyl accident. We therefore aimed to examine the data of thyroid cancers at our center, Rize city which is located in the eastern Black Sea region. METHODS: This retrospective study included the patients with histologically proven thyroid cancer at our center between January 2008 and May 2012. Pathologic examinations of thyroidectomy materials were reviewed. We evaluated patients' age, gender, size of the primary tumor (all sizes, < 1 cm, 1 - 2.9 cm, 3 - 3.9 cm and ≥ 4 cm), multicentricity, histologic subtypes of thyroid cancer, the presence of lymphatic, vascular, capsule and the extrathyroidal invasion. RESULTS: Five hundred and forty-seven of the 3,556 patients were diagnosed with thyroid cancer. The mean age of the patients was 49.31 ± 0.49 years. The histopathologic diagnosis of patients was papillary carcinoma in 533 (97.4%) and the tumor size was < 1 cm in 53.6% of the patients. The presence of multicentricity was detected in 47% of the patients. CONCLUSION: The portion of thyroid carcinomas in all thyroidectomies was 15.4% in our institution 27 years after the Chernobyl accident.
