Purpose: From a clinical perspective, the full spectrum of Sars–CoV–2–infected patients has not yet been defined. This study aimed to evaluate whether liver density on computed tomography (CT) scan and serum insulin-like growth factor 1 (IGF1) values can explain the clinical variability of COVID–19 cases.Methods: We performed a retrospective study including SARS–CoV–2–infected patients hospitalized from March 2020 to Ma...

Central pontine myelinolysis (CPM) is a neurological disorder typically caused by rapid correction of severe chronic hyponatremia. Conditions causing a hyperosmolar state can also cause CPM, but it is rarely seen in diabetes. We report the case of a 33-year-old woman with personal history of Type 1 Diabetes since she was 9 years old with very poor metabolic control (A1hbC 15%) and microvascular complications, who attended the emergency department due to left hemicranial headac...

Background: Medical treatment for acromegaly (characterized by excess growth hormone [GH] production) includes somatostatin receptor ligands (SRLs), dopamine agonists (DAs), and GH receptor antagonists (GHRAs). However, recent real-world United States (US) treatment evaluations are few. We present treatment patterns for patients receiving medications for acromegaly (1/1/2010–31/7/2022).Methods: De-identified data were extracted from MarketScan&...

Background: PET/CT scan with 18F-fluoro-dihydroxyphenylalanine (18F–DOPA) is an emerging useful tool in medullary thyroid cancer (MTC) patients with high calcitonin (CTN) values. The aim of this study is to evaluate the potential usefulness of 18F-DOPA-PET/CT in MTC patients with biochemical incomplete response (BiR) (detectable CTN values and negative/indeterminate findings at CT scan with i.v. contrast).Materials a...

We report the case of a 34-year-old woman with a personal history of type 1 diabetes mellitus (DM1) since she was 9 years old. Very poor chronic metabolic control stands out despite multiple insulin schemes with multiple complications: nephropathy, retinopathy and peripheral neuropathy. She was admitted to the hospitalization floor due to diabetic ketoacidosis. At admission Hba1c of 15.3%. During admission after treatment with IV insulin, improvement in glycemic control. Nine ...

Background: The diagnosis of PHPT and chronic HypoPT is still challenging, mainly due to the wide spectrum of clinical and biochemical presentation and the lack of validated diagnostic index in literature. The serum Ca/P ratio has been proposed as an accurate tool to diagnose PHPT in a small sample of patients, while no data is available about its possible application for HypoPT.Aim: To validate the serum Ca/P ratio as a diagnostic index for PHPT and to ...

Introduction: The silencing mechanisms of corticotroph tumors (CT) remain unclear. The most feasible hypothesis lies in a post-transcriptional deregulation of the POMC gene, precursor of ACTH. Micro RNAs (miRNAs) are small non-coding RNA molecules involved in the epigenetic regulation of gene expression through their inhibitory action on messenger RNA. miRNAs capable of inhibiting the expression of POMC have been described at the level of neurons of the hypot...

It is known that adult growth hormone deficiency (GHD) is associated with oxidative stress (OS): both GH and IGF-1 exert antioxidant functions. OS is in turn related to systemic inflammation and cardiovascular/oncological risk. Discordant data concerning GH effects on antioxidants are reported. Moreover, no data are available in partial GHD, which can induce cardiovascular alterations. To evaluate oxidative damage on macromolecules and systemic inflammation, 80 patients, studi...

Introduction: Previous results of our group, presented in the ECE last year, showed a lower gene expression of proconvertase PC1/3, involved in the processing of POMC, in silent corticotroph tumors (sCT) than in functioning ones (fCT), overall and in microadenomas. The aim of the present study was to quantify the protein expression of convertases involved in the processing of POMC (PC1/3) and in the degradation of ACTH (PC2, CPE and PAM) in a series of CT.</p...

Introduction: Silent somatotroph tumors (sST) are a pituitary neuroendocrine tumor subtype with positive immunostaining for growth hormone (GH) but without the presence of acromegaly. Unlike silent corticotroph tumors, there is little information in the literature on sST. The aim of the present study was to study the demographic, clinical and molecular characteristics in a series of ST in order to compare sST and functioning ST (fST).Methods: We have stu...
