Purpose: High serum homocysteine (HCY) and indirectly deficiency of folate and/or vitamin B12 stimulate bone resorption and adversely affect collagen cross-linking. The aim of this study was the evaluation of serum levels of HCY, folate and vitamin B12 in patients with Paget’s disease of bone (PDB) and the effect of zoledronic acid (ZOL) on their serum levels.Methods: This was a prospective open-label cohort study, with a control arm at baseline. Ni...

Objectives: Neurofibromatosis type 1 (NF1) is an autosomal, dominant, genetic disorder. The genetic lesion in neurofibromatosis type 1 is located at locus 17q11.2 that harbors the neurofibromin gene. Patients have 3-4 times higher possibility to develop malignancies relative to the general population. The endocrine manifestations of neurofibromatosis include precocious puberty, short stature, osteoporosis and pheochromocytoma. We present a patient with neurofibromatosis type 1...

IntroductionMenopausal transition has been associated with an increase in cardiovascular risk, which is possibly linked with the hormonal imbalance following ovarian senescence. Both insulin levels and circulating androgens (FAI) have been associated with endothelial dysfunction, through studies evaluating flow mediated dilation (FMD). We aimed to investigate whether the link between these hormones and FMD might be explained by markers of oxidative stres...

Introduction: Liraglutide treatment reduces cardiovascular complications in patients with diabetes mellitus (DM), which may imply a favorable impact on the endothelial function. The aim of the present study was to investigate in vitro the effect of liraglutide on endothelial redox balance and the parallel expression of CRH, UCN1, 2 and 3 neuropeptides, under normoglycemic and hyperglycemic conditions.Methods: Macroendothelial cell line EAhy926 w...

Background: Incidence of non-functioning pituitary macroadenoma (NFPMA) is very rare in pregnancy. We describe a case of complicated non-functioning pituitary macroadenoma presented during pregnancy. 26 year old female at 21 weeks gestation presented to emergency services with worsening headaches, nausea and vomiting for 2-3 months. This was associated with transient double vision and confusion since 2 days. She was admitted to emergency department 3 weeks ago with vomiting an...

Introduction: Endogenous subclinical hypercortisolism occurs in 5-30% of patients with adrenal incidentalomas. Adrenal adenoma is the commonest cause of autonomous cortisol secretion (ACS), while primary bilateral macronodular adrenal hyperplasia (PBMAH) is rare. In both, ACS results from activation of the cAMP/PKA pathway. This may be triggered by ligands, other than ACTH, acting upon aberrant G-protein coupled receptors (GPCRs), which may also control locally produced ACTH i...

Objective: Parathyroidectomy (PTx) improves quality of life (QoL) in patients with primary hyperparathyroidism (PHPT). Whether this effect is modified according to the patients’ age is unknown. The aim of this study was to evaluate the impact of age on the effect of PTx on QoL and frailty in patients with PHPT, six months post-PTx. Methods: This was a prospective cohort study, including patients with PHPT, admitted from January 2016 to December 2019...

Introduction: Graves orbitopathy (GO) is an inflammatory condition of the orbital fat and muscles and affect 30-50% of patients with Graves’ disease. The first-line treatment of moderate to severe GO according to EUGOGO is intravenous glucocorticoids, but 20-30% of the cases appear to be corticosteroid resistant or refractory. Promising results have been described with Tocilizumab (TCZ) as a second-line moderate to severe GO treatment.Case presentat...

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...

Introduction: Idiopathic Isolated Adrenocorticotropic hormone (ACTH) deficiency (IIAD) is a rare cause of secondary adrenal insufficiency. It can present with a variety of clinical symptoms, mainly chronic fatigue and euvolemic hyponatraemia, and may coexist with autoimmune disease, most commonly Hashimoto’s thyroiditis. Radiographically, an empty sella turcica image can be seen. We present 3 cases of isolated ACTH deficiency.Case 1: A 47-year-old w...
