Abstract
Hypoparathyroidism is an orphan disease with ill-defined epidemiology that is subject to geographic variability. We conducted this study to assess the demographics, etiologic distribution, treatment patterns and complication frequency of patients with chronic hypoparathyroidism in Turkey. This is a retrospective, cross-sectional database study, with collaboration of 30 endocrinology centers located in 20 cities across seven geographical regions of Turkey. A total of 830 adults (mean age 49.6 ± 13.5 years; female 81.2%) with hypoparathyroidism (mean duration 9.7 ± 9.0 years) were included in the final analysis. Hypoparathyroidism was predominantly surgery-induced (n = 686, 82.6%). The insulting surgeries was carried out mostly due to benign causes in postsurgical group (SG) (n = 504, 73.5%) while patients in nonsurgical group (NSG) was most frequently classified as idiopathic (n = 103, 71.5%). The treatment was highly dependent on calcium salts (n = 771, 92.9%), calcitriol (n = 786, 94.7%) and to a lower extent cholecalciferol use (n = 635, 76.5%) while the rate of parathyroid hormone (n = 2, 0.2%) use was low. Serum calcium levels were most frequently kept in the normal range (sCa 8.5-10.5 mg/dL, n = 383, 46.1%) which might be higher than desired for this patient group. NSG had a lower mean plasma PTH concentration (6.42 ± 5.53 vs. 9.09 ± 7.08 ng/l, p < 0.0001), higher daily intake of elementary calcium (2038 ± 1214 vs. 1846 ± 1355 mg/day, p = 0.0193) and calcitriol (0.78 ± 0.39 vs. 0.69 ± 0.38 mcg/day, p = 0.0057), a higher rate of chronic renal disease (9.7% vs. 3.6%, p = 0.0017), epilepsy (6.3% vs. 1.6%, p = 0.0009), intracranial calcifications (11.8% vs. 7.3%, p < 0.0001) and cataracts (22.2% vs. 13.7%, p = 0.0096) compared to SG. In conclusion, postsurgical hypoparathyroidism is the dominant etiology of hypoparathyroidism in Turkey while the nonsurgical patients have a higher disease burden with greater need for medications and increased risk of complications than the postsurgical patients.

Abstract
OBJECTIVES Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Radioactive iodine (RAI) therapy is used for remnant ablation following thyroidectomy. Side effects such as dysphagia, xerostomia, and sialoadenitis may occur. We aimed to determine the differences in the parotid and submandibulary glands between healthy patients and patients with PTC who had undergone RAI therapy and have dry mouth symptoms using both shear wave elastography and ultrasonography. METHODS We enrolled 30 patients with PTC who had undergone RAI therapy following surgery and 30 healthy controls. Ultrasonography and shear wave elastography of submandibular and parotid glands were performed. The volume of the submandibular glands and the thickness of parotid glands were determined. Ten independent measurements were obtained from each gland, with the region of interest placed at different points on the glands. The mean shear wave velocities (SWVs) were calculated and compared between the patients and controls. RESULTS In the PTC group, there was a significant reduction in the volume of the submandibular glands (P < .05) and in the thickness of the parotid glands (P < .05) compared with the control group. The mean SWVs of the parotid glands and submandibular glands were significantly higher in the PTC group compared with the control group (P < .0001). The SWVs of the parotid glands were higher than the SWVs of the submandibular glands (P < .0001). CONCLUSIONS Shear wave elastography could be a noninvasive and easy assessment method of parotid and submandibular glands in patients who had undergone RAI therapy and experience dry mouth.

Abstract
Introduction Our aim was to investigate the relationship between serum omentin-1 levels and endothelial dysfunction in obese patients. Material and Methods We evaluated 50 obese patients, and age/gender matched 45 healthy non-obese subjects as controls. Oral glucose tolerance test, lipid parameters, uric acid levels, homeostatic model assessment-insulin resistance (HOMA-IR) index, serum omentin-1 levels and flow mediated dilatation (FMD) % were measured in all subjects. Body compositions were analyzed with bioelectrical impedance method using a Tanita Body Composition Analyzer and ViScan. Results Serum omentin-1 levels were found significantly lower in obese population compared to the control subjects. FMD response was significantly decreased in obese population. There was a significant positive correlation between serum omentin-1 levels and FMD response (r=0.359, p<0.001). Serum omentin-1 levels were negatively correlated with body mass index (BMI), waist circumference, total fat percentage, visceral fat, fasting insulin and HOMA-IR index. Conclusion Lower serum omentin-1 levels and decreased FMD response may be an early marker of endothelial dysfunction in obese patients.

Abstract
PURPOSE Thyroglobulin (Tg) assessment in the needle washout after fine-needle aspiration biopsy (FNAB) of a suspicious neck lymph node (LN) is known to improve the diagnostic accuracy in patients with papillary thyroid cancer (PTC). However, there is still controversy on the best diagnostic cut-off levels for FNAB-Tg and whether thyroglobulin antibody (TgAb) positivity affects FNAB-Tg. The objectives of this study were to determine (i) the diagnostic power of different cut-offs for FNAB-Tg and (ii) if serum TgAb(+) negatively affects the FNAB-Tg evaluation. METHODS This was a retrospective cohort study analyzing PTC patients with suspicious neck LNs, in a university hospital setting, from October 2009 to October 2013. In total, 103 patients with PTC (226 LNs) undergoing ultrasound-guided FNAB for LNs were included. Cytology and FNAB-Tg levels were compared in reference to LN histopathology and the effect of TgAb(+) on FNAB-Tg levels was evaluated. RESULTS The diagnostic accuracies of FNAB-Tg cut-off of 1 and 10 ng/mL were 94.1% and 88.2%, respectively. Raising the cut-off from 1 to 10 ng/mL led to decreased sensitivity rates (91.9% vs. 83.9%). The receiver operating characteristic curve analysis demonstrated that the best FNAB-Tg cut-off was 1.2 ng/mL. There were no LNs with an FNAB-Tg ≥ 10 ng/mL that turned out to be cytologically or histopathologically benign. FNAB-Tg levels of the histopathologically malignant LNs were similar between TgAb (+) and TgAb (-) patients (p = 0.546). Serum Tg predicted FNAB-Tg levels above 1 ng/mL (p = 0.002) and FNAB-Tg predicted malignant histopathology (p = 0.004), both independently of the TgAb status of the patient. CONCLUSIONS FNAB-Tg ≥ 1 ng/mL has a superior diagnostic power, irrespective of TgAb (+), in PTC patients with suspected LN involvement.

Abstract
Hypothyroidism is associated with changes in bone metabolism. The impact of hypothyroidism and the associated autoimmunity on the mediators of bone turnover in Hashimoto's thyroiditis (HT) is not known. In this study, we assessed the levels of OPG, RANKL, and IL-6 along with markers of bone formation as osteocalcin (OC) and markers of bone resorption as type 1 collagen C telopeptide (CTX) and tartrate-resistant acid phosphatase isoform 5b (TRAcP 5b) in 30 hypothyroid and 30 euthyroid premenopausal HT patients and 20 healthy premenopausal controls. We found that TRAcP 5b (p = 0.006), CTX (p = 0.01), OC (p = 0.017), and IL-6 (p < 0.001) levels were lower in the hypothyroid group compared to euthyroid HT patients and controls. OPG levels were higher (p < 0.001) and RANKL levels were lower (p = 0.021) in hypothyroid and euthyroid HT patients compared to controls. TSH was negatively correlated with IL-6 (rho = -0.434, p < 0.001), OC (rho = -0.313, p = 0.006), TRAcP 5b (rho = -0.335, p = 0.003), and positively correlated with OPG (rho = 0.248, p = 0.029). RANKL/OPG ratio was independently associated with the presence of HT. In conclusion, bone turnover is slowed down by hypothyroidism in premenopausal patients with HT. Thyroid autoimmunity might have a unique impact on OPG/RANKL levels apart from the resultant hypothyroidism.

Abstract
The disrupted autoimmune response in Hashimoto's thyroiditis (HT) has long been considered to be dominantly T helper type 1 (Th1) mediated. Recent advances in the field of immunology have introduced a new class of effector T cells, named 'Th17', which plays important roles in autoimmune disorders once thought to be merely Th1 mediated. We aimed to examine the levels of major Th17 cytokines in patients with HT in this study. We studied serum interleukin 17 (IL-17) and interleukin 23 (IL-23) levels in 46 newly diagnosed, untreated patients with HT (40 women and 6 men, aged 40.0 ± 11.8 years) divided into euthyroid (n=22) and hypothyroid (n=24) groups and compared them with age and sex matched 26 healthy euthyroid controls without HT (21 women and 5 men; aged 36.0 ± 12.9 years). Serum IL-17 and IL-23 levels were significantly different among euthyroid and hypothyroid HT patients and controls, with highest levels obtained in the euthyroid HT group (p=0.041 for IL-17 and p<0.001 for IL-23). TSH was negatively and FT4 was positively correlated with IL-17 (p=0.016 for TSH and p=0.004 for FT4) and IL-23 (p<0.001 for TSH and p=0.003 for FT4) levels. There were no correlations between thyroid volumes calculated on thyroid ultrasonography and IL-17 (p=0.630) or IL-23 (p=0.321) levels. In conclusion, the levels of IL-17, one of the major effector cytokines of the Th17 system, and IL-23, which had been implicated in the generation, survival and expansion of Th17 cells, are altered in HT. How thyroid hormone status and the course of disease affect Th17 system in chronic autoimmune thyroiditis needs to be determined with further studies.

Abstract
The mean platelet volume (MPV) is an indicator of the average size and activity of platelets. Elevated MPV values are associated with larger and more active platelets and perceived as a new independent cardiovascular risk factor. The aim of this study was to determine the MPV in women with gestational diabetes mellitus (GDM) and to determine the correlation of MPV with metabolic parameters in GDM. We retrospectively analyzed 30 women with GDM and 38 body mass index-matched women with healthy pregnancies as controls. MPV and platelet counts were recorded in the third trimester and at postpartum 6-12 months for GDM group and in the third trimester for control group. Third-trimester MPV was significantly higher in GDM group compared to control group (8.8 ± 1.0 versus 8.1 ± 0.7 fl, p = 0.002). In women with GDM, there was a significant decrease in MPV in the postpartum period (8.8 ± 1.0 versus 8.1 ± 0.8 fl, p < 0.001). Fasting plasma glucose levels and glucose area under the curve were positively correlated with third trimester MPV (r = 0.346, p = 0.007 and r = 0.346, p = 0.02, respectively). Our results indicate that MPV is increased in GDM. Monitoring MPV, which is widely available in clinical practice, may potentially identify women who will develop gestational diabetes during pregnancy.
