Context. In patients undergoing thyroidectomy for malignant disease, lower quality of life scores were observed in the early postoperative period compared to those undergoing thyroidectomy for benign causes. Objective. Thyroid gland diseases are commonly encountered in society. This study presents health-related quality of life differences in thyroidectomies performed for benign and malignant diseases and the factors affecting this. Design. Patients who underwent thyroidectomy for thyroid disease between January 2021 and January 2022 were evaluated prospectively. Subjects and Methods. The SF 36 questionnaire was applied and interpreted at the 1st and 6th months after thyroidectomy in patients over the age of 18 who did not have a history of previous thyroid surgery. Results. The study included a total of 228 patients. Among them, 171 (75%) were female (male/female: 57/171). Multinodular goiter in benign cases and papillary carcinoma in malignant cases were predominant (68.3% and 90.6%, respectively). SF-36 scores were found to be worse in the malignant group. Conclusion. In patients undergoing thyroidectomy for malignant disease, lower quality of life scores were observed in the early postoperative period compared to those undergoing thyroidectomy for benign causes.

Background. There is no immunohistochemical study to show luteinizing hormone receptor (LHR), estrogen receptor (ER) and progesterone receptor (PR) in the pregnant Fallopian tubes (FT). Objective. To study LHR, ER, PR expression in FT containing an ectopic pregnancy (EP) and during the menstrual phase. Design. Thirty FT were obtained from women diagnosed with EP and twenty FT collected by hysterectomy performed for benign diseases not affecting the tubes were included in this study. Assessment of immunohistochemical expression staining LHR, ER, PR in epithelium, smooth muscle cell and blood vessel endothelium in FT containing an EP and during the different phases of menstrual cycle. Results. In ectopic pregnancy group we found LHR expression in epithelium in 30 cases, muscle cell in 28 cases, and endothelium in 9 cases in FT. In menstrual cycle group we noted LHR expression in FT in epithelium in all cases, muscle cell in 4 cases. Conclusion. There is a significant difference in the proportions of the existence of LH receptor immunostaining in the muscle cells for ectopic pregnancy group as compared to the menstrual cycle groups (p < 0.001). Our findings may suggest that the women who have increased LH receptors on muscle cells in Fallopian tubes are at increased risk for having external pregnancy.

Context. Primary hyperparathyroidism (PHPT), characterized by the inappropriate secretion of parathyroid hormone (PTH) with respect to the extracellular calcium concentration. Curative treatment of PHPT is surgery and bilateral neck exploration has been replaced by minimally invasive parathyroidectomy (MIP), with the advanced imaging technologies combined with radio-guided occult lesion localization (ROLL). Objectives. The present study analyzes the MIP data from 45 patients who underwent surgery for parathyroid adenoma and debates if MIP is a feasible technique for the treatment of PHPT. Design. The study presents the MIP excision data of 45 hyperparathyroidism patients with a 58-month follow up period. Results. Forty-five operations were performed for 48 parathyroid adenomas. The mean duration of operation was 22.7 (12-55) minutes. Mean follow-up was 14.2 (6- 26) months. All patients had normal postoperative calcium levels and PTH levels were normal in the follow-up period, except for one persistent hyperparathyroidism. Conclusions. ROLL-guided MIP is a feasible technique for parathyroid surgery and reduces surgeon based failure. It also provides the widespread application of parathyroid surgery by decreasing the need for specific experience.

Objective. Gestational diabetes mellitus (GDM) is defined as glucose intolerance that\r\nis detected for the first time during pregnancy. Normal pregnancy induces insulin resistance\r\nthrough the diabetogenic effects of placental hormones. Glucose tolerance test results in\r\ntwin and singleton pregnancies were compared in this study.\r\nSubjects and Methods. A total of 360 pregnant women were studied. 200 women\r\n(mean age 31.60?2.10 yr) had singleton pregnancies (Group I) and 160 women (mean age\r\n28.20?2.70 yr) had twin pregnancies (Group II). 50- g, 1- hour glucose tolerance test was\r\nconducted on the first prenatal visit. An abnormal glucose screen defined as glucose > 140\r\nmg/dL was followed by a 100g, 3-hour glucose tolerance test. Gestational diabetes was\r\ndefined as the presence of two or more abnormal values during the 3-hour test.\r\nResults. Gestational diabetes was found in 4 of the 200 (2%) singleton pregnant\r\nwomen and 8 of the 160 (5%) twin pregnant women. Group I (Singleton) was further\r\ndivided into two subgroups according to whether the 1-hr plasma glucose level was < 140\r\nmg/dl (Group Ia) or >140 mg/dL (Group Ib). Likewise, Group II pregnancies was also\r\ndivided into two subgoups on the same basis. Mean screening test glucose levels were found\r\nto be 127.8?14.94 mg/dL in Group Ia and 150.8 ? 18.1 mg/dL in Group Ib women. Mean\r\nscreening test glucose levels of Group IIa subjects was 92.80 ? 18.30 mg/dL while that of\r\nGroup IIb subjects was 154.8 ? 27.0 mg/dL. Mean 1st h glucose levels of 100-g glucose\r\ntolerance test was found to be 131.4 ? 32.58 mg/dL in Group I, and 112.5 ? 39.6 mg/dL in\r\nGroup II. Mean 2nd h glucose tolerance test values were 133.2 ? 28.8 mg/dL in Group I and\r\n100.6?28.8 mg/dL in Group II. Mean 3rd h glucose tolerance test values were 107.6 ? 23.58\r\nmg/dl in Group I and 72?16.9 mg/dL in Group II.\r\nConclusion: Glucose screening results and 100-g, 3- hour glucose tolerance test\r\nvalues have been found to be lower in twin pregnancies than in singleton pregnancies.\r\nTherefore, we suggest that these findings be taken into account in developing diagnostic\r\ncriteria for gestational diabetes in twin or more pregnancies.

Context. Thyroid incidentaloma is a common disorder in endocrinology practice. Current literature regarding the risk of thyroid cancer in incidentalomas found in patients with non-thyroid cancer is limited. Objective. The aim of the present study was to investigate the frequency of thyroid malignancy in thyroid incidentalomas detected in patients with non-thyroid cancer. Design. Case control study. Subjects and Methods. The database of 287 thyroid nodules from 161 patients with a history of nonthyroid cancer followed between 2008 and 2014 were retrospectively evaluated. Results. From 287 thyroid nodules, 69.7 % had a benign final cytology. Thyroid cancer detected in one nodule while follicular neoplasia detected in 4 nodules, atypia of unknown significance (AUS) detected in 10 nodules, Hurthle cell neoplasia detected in 5 nodules and suspicious for malignancy detected in 6 nodules according to fine needle aspiration biopsy results. Metastasis of the non-thyroid cancer to the thyroid gland was detected in 4 nodules. Twenty seven nodules from 15 patients were removed with surgery. There were 3 malignant nodules found after surgery (1 papillary, 1 follicular and 1 medullary cancer). In addition to these three thyroid cancers, two patients with benign nodules had co-incidental thyroid cancer detected after surgery. Finally, 11.1 % of thyroid nodules which underwent thyroid surgery had malignant histopathology except for co-incidental and metastatic cancers. Conclusions. The frequency of thyroid malignancy seems not to be substantially increased in incidental thyroid nodules detected in patients with non-thyroid cancer when these patients were evaluated in nodule-based approach.

Objective. This study aimed to investigate the effect of symptoms of diabetes on the quality of life of individuals with Type 2 diabetes. Method. The study used a cross-sectional design. No sampling procedure was employed in the study; instead, 410 individuals presenting to the Balikesir Atatürk City Hospital Endocrinology and Internal Medicine Polyclinics between December 2016 and July 2017, diagnosed with Type 2 diabetes, and meeting the inclusion criteria were enrolled in the study sample. The study data were collected with a “Socio-demographic Characteristics Questionnaire”, the “Diabetes Symptom Checklist”, and the “SF-36 Quality of Life Questionnaire”. Results. The participants obtained the highest mean scores from the hyperglycemia subscale of the Diabetes Symptoms Checklist (3.35±0.60) and the mental health subscale of the SF-36 Quality of Life Questionnaire (50.65±8.10). The hypoglycemia, cardiology, psychology, and neurology variables included in the model were statistically significant and predicted 35% of the mental subscale score of the SF 36 questionnaire. SF 36 physical subscale score increased as the hypoglycemia, cardiology, psychology, and neurology scores decreased (p<0.05). Conclusion. The participants obtained high scores from the hyperglycemia subscale of the diabetes symptom checklist and mental health subscale of the quality of life questionnaire. Diabetes symptoms were found to affect the quality of life of individuals with diabetes.

Context. Hypothalamic-pituitary-adrenal (HPA) axis irregularities have been described both in bipolar disorder and suicidal behaviour, but few studies have examined the relationship between suicidal behaviours and cortisol levels in bipolar disorder. Objective. We compared HPA axis activity in bipolar I (BPD I) individuals with and without suicidal ideation and behaviour through multiple measurement of serum and salivary cortisol. Design. Cross-sectional, observational study. Subjects and Methods. 75 BPD I patients were assigned into 3 groups (no history of suicidal behaviour, history of suicidal ideation, history of suicide attempt), according to the C-SSRS. Socio-demographical and clinical data was obtained by using MINI 6.0 and a semi-structured questionnaire. Salivary samples were collected using Sarstedt Cortisol Salivette synthetic swab system for two consecutive days at 08:00, 16:00, 23:00 and salivary cortisol concentrations were determined by ELISA technique. A unique 1mg dose of dexamethasone was administered on the first day, at 23:00, after the collection of the saliva sample. Blood was collected on the first day at 8:00 AM and basal morning serum cortisol levels were determined by immunoassay with fluorescence detection. Results. Cortisol parameters in our BPD I sample did not vary significantly in respect to suicidal history. However, patients with a history of suicidal ideation have significantly higher total cortisol outputs than patients with no history of suicidal behaviour in the 18 to 40 age category compared with the above 40 age category. Conclusions. Total cortisol daily output varies significantly in an age-dependent manner in respect to suicidal thoughts in BPD I individuals.

Graves&#8217; orbitopathy usually occurs in thyrotoxic patients at the presentation of the\r\nhyperthyroidism.\r\nAim: we conducted a cross sectional study over 8 and a half years of the relation\r\nbetween Graves&#8217; orbitopathy and thyroid status in patients presenting to our joint thyroidophthalmology\r\nclinic at University Hospital of Wales.\r\nMethods: Patients with active orbitopathy were diagnosed clinically and with\r\nappropriate imaging where necessary. This series excluded patients previously treated with\r\nradioiodine or surgery for Graves&#8217; disease. Of 259 patients 140 (54%) had not had 131I or\r\nsurgical therapy. Thirty four percent of the 140 had never been hyperthyroid of whom 19\r\n(13.5%) were euthyroid. Twenty nine of the 140 (20.7%) were hypothyroid receiving\r\nlevothyroxine at referral. There were no significant differences between the hyperthyroid\r\nand non hyperthyroid groups in the incidence of cigarette smoking, family history of thyroid\r\ndisease or maximum proptosis at presentation.\r\nResults: We found a higher prevalence of smokers than reported in the literature in\r\nmoderate and severe TAO across all thyroid status groups including hypothyroid only\r\npatients. This study has emphasized the occurrence of Graves&#8217; orbitopathy in hypothyroid\r\npatients as well as euthyroid individuals.

Objective. Thyroid diseases coexisting with primary hyperparathyroidism (PHPT) may individually change the diagnosis, treatment and follow-up of the patients. In our study, we aimed to investigate the thyroid diseases coexisting with PHPT and the relation between\r\nthese two clinical situations.\r\nMethods. We retrospectively investigated 255 patients who were diagnosed as PHPT between 2004-2009 in our clinic. The general characteristics of the patients, laboratory tests,\r\nwhich were performed preoperatively, neck ultrasonography, thyroid and parathyroid scintigraphy and fine needle aspiration biopsy (FNAB) results were assessed. Cytological\r\nresults of the nodules with preoperative FNAB were compared with the postoperative histological results.\r\nResults. Of the patients, 49 were male (19.2%) and 206 were female (80.8%). Mean age was 54.5?12.8. Bilateral neck exploration (BNE) was performed on 69 cases (27%),\r\nminimal invasive parathyroidectomy (MIP) on 78 cases (30.5%) and BNE plus thyroidectomy on 108 cases (42.5%). When all thyroid diseases were taken into account,\r\nprevalence of the coexisting thyroid disease was 65%, prevalence of nodular thyroid disease 52.1%, thyroid cancer 16.7% and thyroid dysfunction 11.8%. The mean age of the patients with a nodular goitre was significantly higher than of the patients who did not have nodules\r\n(p<0.001). General demographic data, calcium and PTH levels did not show any difference. Number of nodules was correlated with age (p<0.001, r=0.227).\r\nConclusion. The relation between PHPT and nodular thyroid diseases is coincidental and this can be explained by the fact that both diseases occur in advanced age.

Objective. Personal discrepancies in gastrointestinal physiology might influence responses to GH suppression during OGTT. We aim to compare growth hormone (GH) response during oral glucose tolerance test (OGTT) and intravenous glucose tolerance test (IVGTT). Methods. Data of 18 healthy volunteers were analyzed in the study. Subjects were firstly evaluated with standard 75-g OGTT. In subjects with serum glucose <100 mg/dL at basal state and <140 mg/dL at 120th minute of oral loading, IVGTT was performed after at least 3 days. Serum glucose, insulin and GH levels were measured during two tests. Results. Basal GH levels had a wide distribution ranging from 0.00005 μg/L to 0.768 μg/L (median 0.0145 μg/L). Mean nadir GH level during OGTT was obtained at 60th minute and it was 0.0376 μg/L(range 0.00011-0.387, median 0.0016 μg/L, SD: 0.095, SEM: 0.038). Nadir GH level during IVGTT was observed at 10th minute and it was 0.112 μg/L(range 0.0005-0.770 μg/L, median 0.0053 μg/L, SD: 0.242, SEM: 0.057). There was a statistically significant difference between nadir GH levels obtained during IVGTT and OGTT (p=0.028). Conclusions. We found that mean nadir GH level was significantly higher during IVGTT in healthy subjects. This is a preliminary study and further large scale studies are required to suggest that IVGTT may be used in the diagnosis and follow-up of patients with acromegaly as an alternative to or instead of OGTT.
