Objective: To report a case of a patient diagnosed with latent autoimmune diabetes of adulthood (LADA) based on clinical presentation and positive glutamic acid decarboxylase antibodies (GAD-abs) that converted to antibody negative diabetes after combined treatment with sitagliptin and vitamin D.Methods: A 31-year-old male presented at the emergency room with symptoms of polyuria, polydipsia, and weight loss. Blood glucose was 300 mg/dl with mild ketonur...

Several studies have pointed to a neural regulation of glucose dependent insulinotropic peptide (GIP) secretion. Bombesin is a neuropeptide found in the amphibian brain and gastrointestinal system – homologous to the C terminus of gastrin-releasing protein (GRP) in mammalians, which displays a wide range of metabolic actions.Aim: Aim of this study was to investigate the effect of intracerebroventicular infusion of bombesin in a centrally mediated re...

Background and objective: Multiple Endocrine Neoplasia type 1 (MEN 1) is an autosomal dominant disease characterized by a broad clinical spectrum. Previous multi-center studies, that analyzed large groups of patients with MEN 1 have been reported before but long term follow up data of these patients focusing exclusively on primary hyperparathyroidism (PHPT) are scarce.Patients and Methods: In this retrospective cohort study we include all patients with P...

Purpose: Pheochromocytomas (PCs) and paragangliomas (PGLs) are rare neuroendocrine tumors arising from chromaffin cells of the adrenal medulla and the sympathetic/parasympathetic neural ganglia, respectively. Metastatic PCs/PGLs occur in about 5-26% of cases. Their management and diagnosis still remain a challenge due to their heterogeneity, the absence of guidelines and the few prognostic tools.Aim: The aim of this study was to describe clinical and gen...

Objective: To report a case of hypogonadism reversal and spontaneous puberty in a craniopharyngioma patient who suffered from hypopituitarism as a result of complete surgical resection.Methods: A 13-year-old boy with hypopituitarism was evaluated for right testicular sensitivity.At the age of 6 the child presented with growth arrest and a craniopharyngioma causing pituitary insufficiency was diagnosed. Treatment with hydrocortisnon...

Objective: To report the unusual presentation of a thyrotropinoma in a patient with: i) accelerated bone turnover, evident as osteopenia and increased serum alkaline phosphatase level, and ii) a pericardial effusion, years before diagnosis, that resolved completely following surgery and somatostatin analogue treatment.Case report: A 38-year-old man had been treated for years for presumed hypothyroidism with thyroxine supplementation based on elevated TSH...

Background: Although primary hyperparathyroidism (PHPT) has been associated with diabetes mellitus (DM), the etiological link is not clear and the effect of parathyroidectomy is controversial.The aim of this observational study was to investigate the metabolic link between calciotropic hormones and glucose metabolism in PHPT patients before and after parathyroidectomy.Methods: Twenty-four consecutive patients with PHPT (Group-A) without DM were included ...

Background: Hypercholesterolemia has an established causal role in the progression of atherosclerosis and development of cardiovascular disease (CVD). In studies carried out after 2002, the estimated prevalence of self-reported dyslipidemia in the Greek population ranges from 11% to 23%, whereas approximately 35% of mortality in Greece is attributed to cardiovascular disease (CVD). Relevant real-life data, however, are scarce.Methods: In the present stud...

Background: The present study is designed to assess the incidence of osteoporotic fractures and the associated risk factors and particularly those used to predict the 10-year fracture risk in FRAX score based on data gathered in general practitioner’s records of rural Greece.Patients and methods: We conducted a retrospective analysis of all patients with osteoporosis presented between October 2013 and December 2014. Data from medical records includi...

Background: Vitamin D receptor (VDR) and progesterone receptor (PR) expression have been described before in papillary thyroid carcinoma but data regarding association of this expression with tumour histological characteristics are scarce.Materials and methods: Formalin-fixed, paraffin-embedded specimens from adult patients with papillary thyroid carcinoma (PTC), who underwent total thyroidectomy from 2009 to September 2012 were retrieved. Data regarding...
