Introduction: Non-classical congenital adrenal hyperplasia (NCCAH) is a common autosomal recessive disorder characterized by androgen excess. It classically presents in later life with symptoms of acne, hirsutism, and premature adrenarche. This case illustrates a rare case presentation of NCCAH in early infancy.Clinical case: An 18 day old term male infant was brought to the A&E for 9% weight loss. On review he was mottled, but otherwise examination ...

59-year-old gentleman with known succinate dehydrogenase complex subunit C (SDHC) gene mutation attended endocrine clinic with non-specific symptoms. Past medical history included glomus jugulare paraganglioma (PGL) surgically treated (1993, 2003) with residual disease, macroprolactinoma treated with cabergoline since 2010, and BPH treated with finasteride and tamsulosin. His brother has glomus vagale. Clinical examination was unremarkable. Plasma metanephrine ranged between 3...

Background: Following pituitary surgery, dynamic testing with insulin tolerance (ITT) or glucagon stimulation testing (GST) is used to identify patients with secondary hypocortisolism who require glucocorticoids. High glucocorticoid replacement doses are associated with adverse effects, and the optimal replacement dose is unknown.Aim: We aimed to assess the interpretation of dynamic testing post pituitary surgery in clinical practice and its relation wit...

Background: After pituitary surgery patients require HPA axis assessment, that is achieved with postoperative cortisol measurements and, in selected patients whose post-operative cortisol measurements are inconclusive, with the insulin tolerance test (ITT) and the glucagon stimulation test (GST).Aim: We aimed to assess the performance of the day 2/3 post-operative cortisol in predicting the HPA axis sufficiency as assessed by the ITT and the GST.<p c...

Introduction: Most adolescents with GID have no overt functional or phenotypic abnormalities to explain their presentation. Currently all female to male (FtM) persons undergo detailed evaluation of adrenal function. This study aimed to determine whether subtle abnormalities of adrenal were present and what the appropriate investigation schedule should be.Methods: Over the past 4 years, 55 biological females aged mean age 16.54 years (13.46–18.37) we...

Introduction: Adrenal venous sampling (AVS) is the criterion standard method of lateralisation in primary aldosteronism (PA). Despite this pivotal role, there is limited consensus and significant variability between centres related to many of the technical aspects of AVS. In this study, we sought to address whether variations in two different technical aspects of AVS altered parameters and interpretation, namely: 1. Peripheral sample site 2. Method of adrenal vein (AV) venesec...

Introduction: In a prospective within-patient study (MATCH) 11C-metomidate PET-CT (MTO) was an accurate non-invasive alternative to adrenal vein sampling in the detection of unilateral PA1. Post-adrenalectomy (ADX), 24/78 (30%) patients achieved complete clinical success (PASO consensus) at 6 months, but 75% achieved reduction in B-type natriuretic peptide (BNP).Aim: To determine: 1. the number of patients who sustain complete clinical success...
