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’ 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’ 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’ 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’ 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.

Background. Plasma level of ghrelin is possibly reduced in Helicobacter pylori infection and may account for the resultant failure to thrive. Objective. To investigate relationships between Helicobacter pylori infection, and plasma level of ghrelin, anthropometric measurements, appetite, educational and economical status of parents. Methods. Ninety-four children were screened for Helicobacter pylori infection with C-14 urea breath test. Anthropometric measurements were performed in Helicobacter pylori (+) and (-) groups. Plasma ghrelin was measured. Parents were asked to fill out the questionnaire prepared by the researcher on the number of family members, parents’ level of education, monthly income and children’s status for appetite. Results. Plasma ghrelin was lower in Helicobacter pylori (+) group (20.00 ± 22.10 ng/mL), compared to Helicobacter pylori (-) group (79.72 ± 78.13 ng/mL). The percentiles of measurements for height, weight and body mass index were higher in Helicobacter pylori (-) group. Results of C-14 urea breath test were negatively correlated with height, weight and body mass index; however, no correlation was detected between the results of C-14 urea breath test, and plasma ghrelin, number of family members, levels of parents’ education and income. A negative correlation was observed between the results of C-14 urea breath test and appetite. Conclusions. Helicobacter pylori infection is considered to play a restricting role in growth potential by decreasing ghrelin level in children. Moreover, the existence of a negative correlation between the results of C-14 UBT, and weight, height and body mass index suggests a possible link between Helicobacter pylori infection and poor growth.

Objective. Congenital hypothyroidism (CH) is one of the common preventable causes of intellectual disability in neonates, by early detection through neonatal screening. We present the 8-year experience of the National Institute for Mother and Child Health (INSMC) in using MEDILOG national registry for the neonatal screening of CH. Methods. Neonatal screening for CH, done by TSH measurement in dried blood spot, is organized in 5 regional centers, each with a reference laboratory. Results. In 2018 80% of all the newborns, from 80% of the maternity hospitals, were registered in MEDILOG. After re-testing of TSH and T4/FT4 from venous blood in positive cases, the incidence of confirmed CH in 2018 was 1/3576 - 1/ 4746. In INSMC center (which includes 26 counties and Bucharest, out of 41 counties), in 2018 the incidence of positive CH cases at screening was 1/2094 (TSH cut-off ≥17 mIU/L) and of confirmed CH cases 1/3576 newborns. For positive screening cases, the median duration from birth to the INSMC laboratory result was 19 days: median of 9 days between screening and laboratory registration and 6 days between registration and test result. Conclusion. MEDILOG registry is a practical instrument for monitoring the steps of neonatal CH screening, the incidence of CH, the evolution of the diagnosed cases, for evaluation of iodine deficiency (by neonatal TSH), and also for research, with the aim of improving early disease detection and treatment.

Aim is to evaluate atherosclerotic risk factors and carotid intima media thickness [CIMT] in offspring of type 2 Diabetes Mellitus [DM] patients with normal glucose tolerance. Methods. We evaluated 96 offspring of Type 2 DM patients and 39 healthy control who were in similar age, sex and body mass. We measured fasting blood glucose [FBG], postprandial blood glucose [PBG], insulin, uric acid, homocystein, fibrinogen, HOMA-IR, lipid profile, hsCRP, microalbuminuria, glycosylated hemoglobin A1c and CIMT by Doppler ultrasonography. Results. FBG was found higher in study group [p<0.001]. The HOMA-IR was 1.7±0.98 and 1.2±0.58 mg/dL x uUI/mL for study and control group, respectively [p=0.007]. TCholesterol, triglycerides, HDL-C, LDL-C and homocystein levels were not different. HsCRP and fibrinogen levels were higher in study group [p=0.014 and p=0.035, respectively]. Microalbuminuria levels were higher in study group but not significant [p=0.111]. CIMT in study group increased distinctively [p<0,001]. In regression analysis, being in study group causes a significant increase on the mean CIMT level by 0.057 mm [0.029-0.086] Conclusion. Our study demonstrated that various atherosclerotic risk factors are aggregated in offspring of Type 2 DM patients having NGT even before they develop glucose intolerance. Having a diabetic family alone might be effective in developing increased CIMT.

Parathyroid cancer is an uncommon endocrine malignancy. It has slow clinical course and low malignancy potential. It represents 1% of primary hyperparathyroidism. It results with more agrressive biological behaviour and severe clinical condition than benign reasons. Extended resection in the first operation is essential for PC treatment and decreases local recurrence that is observed in high frequency. Palliative surgery should be considered in patients with unresectable tumor. Immunotherapy and recent interventional radiological procedures are considered for patients that are unfit to surgery. Effect of adjuvant chemotherapy and radiotherapy is limited however recent immunization studies are promising. Parathyroid cancer epidemiology, staging system, diagnosis and advancements in treatment are considered according to recent literature in this review.

Background. Sweet's syndrome (SS) or acute febrile neutrophilic dermatosis is a dermatological illness that can be described by tender erythematous plaques or nodules and acute onset fever. The etiology is multifactorial and is not fully understood. SS is separated in three subclasses: classical, malignancy-associated, and drug-induced. It was shown that this syndrome can reveal an underlying hematological or solid malignancy. Case presentation. We report the case of a 55-yearold female patient referred to the Urology department for management of pheochromocytoma in the right adrenal gland, revealed by abdominal imaging in another medical unit during the evaluation and diagnosis of multiple mucocutaneous lesions, characterized by erythematousviolaceous plaques and nodules, and painful aphthous ulcers of the tongue. The eruption of each lesion was preceded by low-grade fever and chills. The hormonal profile highlighted the presence of elevated normetanephrines. We performed 3D laparoscopic transperitoneal right adrenalectomy after preoperative treatment with alpha blocker therapy. The clinical outcome was favourable, given that the cutaneous lesions started to heal after the surgery. Conclusions. Sweet’s syndrome in association with pheochromocytoma is a very rare condition, only few cases were described in literature to our knowledge. The multidisciplinary collaboration is extremely important in the management of such cases.

Iodine plays an important biochemical role in human organism; its insufficiency produces disturbances in the synthesis of thyroid hormones and increases the volume of the thyroid gland. Iodine deficiency in pregnant women has severe consequences on maternal\r\nbody and fetal development. The aim of this study was to determine the incidence of iodine deficiency in pregnant women from Cluj city and county. Urinary iodine levels were determined by the Sandell-Kolthoff method. A group of 100 pregnant women was studied. The results show a mean iodine concentration at the lower limit of the normal range (107.58 ? 91.16 &#956;g/L), not correlated with the period of pregnancy.
