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...

Background: Apart from traditional cardiovascular-risk factors and fluctuating sex hormone levels, environmental and lifestyle factors might also contribute to the heightened cardiovascular risk after menopause.Objective: To explore whether nutritional factors are associated with subclinical vessel disease in postmenopausal women.Methods: This cross-sectional study recruited 310 apparently healthy postmenopausal women, attending a ...

Introduction: Metastatic phaeochromocytomas (PCC) and paragangliomas (PGL), collectively known as metastatic PPGL (mPPGL), represent uncommon neuroendocrine tumours for which no standardized treatment guidelines exist. The emerging therapeutic modality employing 177Lu-DOTATATE Peptide Receptor Radionuclide Therapy (PRRT) has exhibited favourable tolerability in the management of these patients.Methods: In this...

Paradoxical severe hypercalcemia is a rare phenomenon observed in some patients in delayed phase following rhabdomyolysis. We present a case of 33-year-old male who developed severe hypercalcemia following successful treatment of rhabdomyolysis. Patient was admitted with agitation and disinhibition, was intubated in A&E due to metabolic acidosis (pH 6.7), hyperkalemia (K+ 7.3 mmol/l), lactic acidosis (23 mmol/l), and pyrexia (40°C). Toxicology screening shown presence...

Introduction: Hypocalcaemia is rare in patients with malignancy, occurring in <2% of patients with malignancy. Osteoblastic bone metastases as an aetiology of hypocalcaemia are further rare.Case description: A 75-year-old male presented to emergency with back pain, and immobility. He was diagnosed to have prostate cancer in 2019. A bone scan in April 2022 showed extensive sclerotic metastases involving axial and prox...

Background: Milk- alkali syndrome (MAS), characterized by the triad of hypercalcemia, metabolic alkalosis, and renal dysfunction, is increasingly recognized as a complication of calcium supplementation, particularly in the management of hypoparathyroidism. Some have proposed should be called calcium- alkali syndrome (CAS). We delineate two cases of CAS and provide a review of relevant literature, emphasizing the endocrine aspects of CAS.Case Presentation...

Background: Neuroendocrine neoplasms (NENs) are rather uncommon while they have an incidence of no more than 0,5 per 100.000 people. The aim of this study is to investigate the prevalence of second neoplasms among patients diagnosed with sporadic NENs.Methods: Clinical and histological data from patients followed to our NENs clinic between 2020-2023 were retrospectively evaluated. Patients with a known genetic syndrome were excluded from the analysis.</p...
