Background: Measurement of the peripheral cortisol concentration is necessary for calculating selectivity ratio (SR) based on which is AVS success evaluated.Objective: The goal of this study was to assess the necessity for two peripheral cortisol measurements in sequential AVS, one after cannulation of the adrenal vein on one side, and the second after cannulation on the other side.Methods: This retrospective study included 142 bil...

Background: A few studies have shown that aldosterone has negative impact on metabolic parameters.Objectives: The aim of the study was to evaluate metabolic parameters in patients with primary aldosteronism (PA) before and one year after adrenalectomy.Methods: In this retrospective study, we examined 51 patients (median age 50 years, IQR 43–55; 55% male) who underwent adrenalectomy for PA between 2016 and 2022. Patients with d...

Background: Placentation (invasion of the placenta into the maternal endometrium) is hypothesised to be critical for healthy placental function and is abnormal in two thirds of miscarriages. Kisspeptin has emerged as a putative regulator of physiological placentation; it is highly expressed in placental syncytiotrophoblasts and could play an important paracrine role in the regulation of placentation. Circulating kisspeptin levels are considerably raised during healthy pregnanc...

Background: Placentation (invasion of the placenta into the maternal endometrium of pregnancy known as the decidua) is hypothesised to be critical for healthy placental function and is abnormal in two thirds of miscarriage. Kisspeptin has emerged as a putative regulator of physiological placentation; it is highly expressed in placental syncitio-trophoblasts, whereas its receptor is expressed in both syncitio- and cyto-trophoblasts, such that kisspeptin is hypothesized to play ...

Case history: A 74-year-old gentleman with primary aldosteronism (PA) was referred for the ‘MATCH’ study – a prospective comparison of 11C-metomidate PET CT with adrenal vein sampling. He took no exogenous steroids.Investigations: Na 147 mmol/l, K 3.7 mmol/l, aldosterone 496 pmol/l, renin activity <0.17 nmol/l per h, random cortisol 247 nmol/l and concomitant ACTH 9.3 ng/l. Two overnight dexamethasone suppression tests recorded values ...

Introduction: Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, autonomic dysregulation, and neuro-endocrine tumour (ROHHAD-NET) is a rare syndrome associated with high morbidity and mortality. With no clear aetiology, diagnosis is based on constellation of clinical features. Management is supportive, although various immunosuppressive agents have been used with variable benefits. We present 3 cases of ROHHAD with heterogeneous presentations and clinical feat...

Background: Learning through various online platforms is very common nowadays and its popularity has increased especially during the pandemic period. Nowadays, medical professionals are turning more than ever to online education through available online books, websites, and various online platforms. The aim of this study was to show that virtual training can improve the knowledge and confidence of young endocrinologists.Methods: The Croatian Section for ...

Background: Characterisation of large adrenal lesion is challenging. There is no single robust imaging marker in defining benignity, especially for lesions which are greater than 4cm and are believed to carry increased risk of malignancy.A radiolabelled cholesterol analog tracer, I-131-Norcholesterol (NP-59), localises to adrenal cortical lesions. It has an established role in Conn’s syndrome. It is not expected to concent...

Background: Neuroendocrine tumours (NETs) are rare malignancies; over 60% of primary lesions arise in the gastrointestinal tract and pancreas. Despite several practice-changing clinical trials, uncertainty persists around the most efficacious treatment sequence in patients with advanced well-differentiated gastroenteropancreatic (GEP) NETs, particularly in relation to peptide receptor radionuclide therapy (PRRT). This study aimed to investigate the progression-free survival (P...
