Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is showing a rapid and continuous evolution in terms of new waves, the spread of variants and the evidence of reinfections. The growing heterogeneity of clinical presentation requires the identification of underlying pathogenic mechanisms to allow a better risk stratification. Previous studies analysed the role of sex hormones in disease severity demonstrating in male patients the association of...

Background: In the last decades mini-invasive techniques have been proposed to reduce costs and complications of emithyroidectomy and thyroidectomy, both for benign nodular goiter and thyroid microcarcinoma, and image-guided laser and radiofrequency ablation are the most used.Purpose: To investigate short and long-term efficacy of image-guided laser and radiofrequency ablation as therapy options for benign nodular goiter.Methods: F...

Introduction: Cyclic Cushing’s syndrome (cCS) is a rare condition characterized by periods of excessive cortisol secretion (peaks), alternating with phases of eucortisolism (through). In most cases, cCS is caused by an ACTH-secreting pituitary tumor, while only few cases of cyclic ectopic ACTH secretion (cEAS) have been described.Case presentation: In February 2023, a 58-year-old woman was referred to our Endocrine Unit due to a 10-year history of r...

Corticotroph Pituitary Neuroendocrine Tumours (Co-PitNETs) show significant differences in cortisol secretion, responses to existing therapies and gene expression andstill pose a challenge for patient management.Aim: to explore possible novel therapeutic targets in Co-PitNETs (functioning and silent) through transcriptome analysis (RNA sequencing) and immunohistochemistry. Methods: Transcriptomic data from a previously reported dat...

PAM encodes a multifunctional protein recognized as an important regulator of hormone amidation and secretion. Since PAM germline mutations have been recently identified in patients with PitNETs, it has been proposed as a candidate gene associated with pituitary hypersecretion.Aim: To characterize PAM expression in a large cohort of PitNETs through immunohistochemistry and transcriptome analysis (RNA sequencing).M...

The bone strain index (BSI) is a marker of bone deformation based on a finite element analysis inferred from dual X-ray absorptiometry (DXA) scans, that has been proposed as a predictor of fractures in osteoporosis. BSI value represents the average equivalent strain in a skeletal site, assuming that a higher strain level (higher BSI) indicates a lower bone’s resistance to loads with consequent higher risk of fractures. BSI index is usually calculated for specific loading ...
