Introduction: Central diabetes insipidus (CDI) occurs due to deficient secretion of arginine vasopressin (AVP) or antidiuretic hormone (ADH) by the posterior pituitary. It is a rare disease with an estimated prevalence of 1:25000. CDI can be acquired or congenital, secondary to malformation or genetics. Familial CDI (genetic inheritance) is mainly autosomal dominant. More than 80 mutations in the AVP gene have been described. In hereditary CDI, the age of onset is variable. Sy...

The GH-receptor antagonist PEG, used as monotherapy or in combination to SA, has been demonstrated to normalize IGF1 levels in up to 90% of acromegalic patients after unsuccessful surgery and/or radiotherapy and resistant to conventional SA treatment. The aim of this study is to evaluate the efficacy and safety of combined treatment with SA plus PEG in a cohort of acromegalic patients resistant to conventional SA therapy. Thirty-two acromegalic patients (17 M, 15 F, age 39.6&#...

The prevalence of gallstones (GS) is increased in acromegaly and is further increased by somatostatin analogue (SA) therapy. The incidence has variously been reported to be between 10 and 63%, but they are often asymptomatic and rarely require definitive management. However, there is evidence suggesting that discontinuation of SA therapy may precipitate acute biliary problems.We have analysed our experience of symptomatic gallstones in all 44 patients (2...

Context: The nadir serum GH level during glucose suppression (OGTT) is recommended in patients treated by surgery, but not during SA treatment. We have shown that patients considered controlled by SA don’t suppress serum GH during OGTT and have impaired disease-specific QoL as compared to patients controlled by surgery. We hypothesize SA treated patients also don’t suppress GH in response to mixed meals.Aim: To compare GH levels during two mixe...

Background: PCO is more prevalent among SA than C and IR is central to its pathogenesis; whilst Type 2 diabetes (DM) is commoner in SA. We compared the phenotype and IR in South Asian and Caucasians with PCOS.Methods: Comparison of consecutive anovular PCOS; 47 SA and 36 Caucasians and their age and weight matched controls (11 SA and 22 Cs).Results: SA presented earlier (age 26 plus/minus 4 v 30.1 plus/minus 5, p = 0.005). BMI (24....

Introduction: Thyrotoxicosis after total thyroidectomy (TT) is mostly iatrogenic. Rarely, an hyperfunctional thyroid remnant or ectopic tissue may be the cause. We report a case of Graves’s disease in a mediastinal thyroid mass presenting 7 years after TT for nontoxic goitre.Case report: A 67-year-old woman presented with palpitations, fatigue and weight loss. She had a history of TT for nontoxic multinodular goitre at the age of 60 without any sign...

Background: Hypercalcaemia due to primary hyperparathyroidism is a rare cause of acute pancreatitis, with a reported prevalence of 1.5–8%.Clinical case: A 25-year-old male patient was referred to the Endocrinology outpatient clinic for hypercalcemia diagnosed in the context of acute pancreatitis. He had medical and surgical pathological antecedents of: clavicle fracture after car accident, cholecystectomy and appendectomy, gastroesophageal reflux di...

Introduction: The height growth is regulated by multiple factors, including specific genetic mutations that ensure correct differentiation and proliferation of chondrocytes. We present a case of double association of haploinsufficiency of the SHOX gene with a mosaic 45,X/46,X,r(Y) karyotype responsible for growth and pubertal delay.Case: Male patient, observed in endocrinology consultation at age of 12, with constitutional delay of grow...

Objective: To report a case of thalassemia major diagnosed per chance when investigated for undetectable HbA1C.Clinical Presentation: A 2-year-old male patient presented with fever since 3 days and moderate pallor. His blood was sent to Biochemistry laboratory for the estimation of HbA1C. Later on it was found that there was no indication for this test in this case. When assayed, his haemoglobin (Hb)A1C was not detectable on a BioRad D10 HPLC ...

Introduction: Conventional systemic therapies have limited role in metastasized neuroendocrine tumors (NET). Therefore an increasing role is attributed to 177Lu labeled somatostatin analogues (SA).Case: Man, 52 years, referred because of NET, diagnosed following liver biopsy for hepatic nodules (liver tissue infiltrated by NET, compatible with metastases). Endoscopic ultrasound revealed pancreatic nodular formation, 40×24 mm; 99</sup...
