Introduction: Dopamine agonists are the mainstay treatment for prolactinomas, but clinical characteristics that predict their effects on prolactin (PRL) suppression and tumour shrinkage are missing. Our study aimed to find measures in early follow-up of men harbouring macroprolactinomas, that will predict dynamics of PRL decrease and adenoma shrinkage.Methods: A single centre historical prospective study, including a consecutive group of 71 men with pitu...

Background: von Hipple-Lindau (VHL) disease comprises hemangioblastomas, renal cell carcinomas (RCC), pheochromocytomas, and pancreatic neuroendocrine tumors (PNET). Diagnosis is based International (two hemangioblastomas, one hemangioblastoma and one visceral lesion, or VHL family history and hemangioblastoma or visceral lesion) or Danish criteria (any two clinical manifestations, one clinical manifestation and family background of VHL or self-genetic diagnosis). The nature o...

Background: Biochemical biomarker DT is used clinically for prognosis prediction in several solid malignancies. The aim of the current analysis was to determine whether biomarker DT has any prognostic utility in patients with NETs.Methods: Patients with NETs (n=184) were enrolled in a prospective study with comprehensive biochemical analysis. The current analysis included subjects with increasing 5-HIAA levels in at least two consecutive measure...

Introduction: Two aetiologies are responsible for postpartum hypopituitarism; Sheehan’s syndrome which develops following traumatic labour, and lymphocytic hypophysitis. Since management of lymphocytic hypophysitis does not require surgery in most cases, pathology is usually absent, and the clinical presentation, in combination with laboratory and imaging characteristics establish the diagnosis. We aimed to describe the various patterns of presentation, including assistin...

Background: About 8–20% of patients with von Hippel-Lindau disease (vHLd) develop pancreatic neuroendocrine tumors (PNETs). However, prognostic markers for these tumors are lacking. The VHL gene mutation type is associated with the clinical phenotype of vHLd. Hence, we aimed to determine whether VHL mutation characteristics may be associated with PNETs phenotype in patients with vHLd.Methods: A prospective study of patients with vHLd and PNETs with ...

Context: Primary aldosteronism (PA) is a common cause of secondary hypertension, and some PA adrenal tumors co-secrete glucocorticoids, causing subclinical or overt Cushing syndrome (CS). We recently reported correlations between hair cortisol concentration (HCC) and serum and urinary levels of cortisol in patients with CS.Objective: To determine correlations of segmental hair cortisol and biochemical markers of a referred cohort of patients for the eval...

Background: Patients with neuroendocrine tumors (NETs) have divergent survival, even when having the same site of primary tumor, and tumor stage and grade. 68Gallium (68Ga)-DOTATATE positron emission tomography (PET)/computed tomography (CT) is a sensitive imaging modality for detecting NETs. The purpose of this study was to determine whether 68Ga-DOTATATE PET/CT imaging has any prognostic utility in patients with NETs.Methods: One hundred and eighty-fou...
