Thymic carcinoma is a rare but aggressive cause of ectopic ACTH secretion, with fewer than 100 reported cases.Hypokalaemic alkalosis was found in a 38 year old woman who presented with a 2-week history of leg swelling, fatigue and dyspnoea. She was not obviously Cushingoid.ACTH-dependent Cushing's Syndrome was confirmed biochemically: urinary free cortisol (UFC) >8500nmol/day and serum cortisol 4060nmol/l, (no suppression on 8...

Objective: To establish the efficacy of CAB as primary and exclusive therapy in the management of macroprolactinomasMethod: Retrospective case note review of all patients with macroprolactinomas treated with CAB since the drug received a UK licence in 1994. Patients: Sixteen patients (8males, 8 females) with mean age at presentation of 42.3yrs (range 22-72 years) were treated with initial CAB doses ranging from 0.5-1mg/week (median 1mg/week). Results: T...

Phaeochromocytoma in association with hypercortisolism is thought to be rare. However we have observed 4 cases in 3 years and question the rarity of this link. In each case there was a dominant adrenal mass (3.6-7.7cm) with contralateral adrenal hyperplasia. Three of the 4 tumours showed increased 123-I-mIBG uptake. Urinary catecholamines ranged from 872-22752nmol/24h (N < 600). Hypercortisolism was present in all 4 patients; sustained in 2 and cyclical in 2. Case 1 (JCEM ...

Background: Cortisol and growth hormone elevations are critical counterregulatory responses to severe hypoglycemia. However, the proportion and clinical characteristics of type 2 diabetic patients who fail to show appropriate cortisol and/or growth hormone secretion in response to severe hypoglycemia have not been investigated.Methods: We measured the plasma cortisol and growth hormone levels in type 2 diabetes with severe hypoglycemia (defined as blood ...

Miscarriage is a very common occurrence in humans, in which blastocyst implantation failure in naturally-occurring and assisted human reproduction occurs in up to 2/3 of all cases. Calcium (Ca2+) has been showed to involve in many cellular signal transduction pathways as well as regulation of cell adhesion, which is necessary for the physiology process of endometrial epithelial cell transformation and stromal cell decidualization during embryo implantation. Previous...

Background: Recently, the triglyceride glucose (TyG) index has been considered a surrogate marker of insulin resistance. Insulin resistance is a well known pathogenic factor in nonalcoholic fatty liver disease (NAFLD). However, few studies have investigated the relationship between the TyG index and liver fibrosis in subjects with NAFLD. Thus, we investigated the relationship between the TyG index and liver fibrosis in Korean adults.Methods: In total, 51...

Introduction: Transoral Robotic Thyroidectomy (TORT) is progressively gaining its ground in robotic thyroid surgery. With accumulated techniques and developments, TORT can also be applied for completion thyroidectomy. We review our experience with the transoral robotic approach to completion thyroidectomy to evaluate the safety and surgical feasibility.Methods: Consecutive patients receiving completion TORT operation were evaluated from a prospective dat...

Background: Telomerase reverse transcriptase (TERT) promoter mutation is a poor prognostic factor in differentiated thyroid carcinoma(DTC). It is thought to play a role in the transformation process to undifferentiated thyroid carcinoma(UTC), but its role as a prognostic factor in UTC is unclear. Therefore, in this study, we investigated whether the TERT promoter mutation acts as as an independent poor prognostic factor in UTC.Methods: Among patients dia...

Background: Treatment options for patients with toxic multinodular goitre (TMNG) include antithyroid medications, thyroidectomy, and radioactive iodine (RAI) therapy. Our aim was to investigate the efficacy of RAI alone compared to combination therapy that includes RAI with medical therapy.Methods: Search was performed using MEDLINE, MEDLINE In-Process (PubMed platform), Embase (Elsevier platform), BIOSIS and Cochrane wa...

Introduction: Mixed gonadal dysgenesis (MGD) is a rare form of difference in sex development (DSD) characterised by mosaic karyotype of 45,X/46,XY and dysgenetic gonads. Gender dysphoria can be associated, the frequency of which is unknown. We describe 2 cases of MGD with gender dysphoria and the conundrum around pubertal induction.Case 1: An 8-year-old, reared as a girl, presented with longstanding concerns about appear...
