Antithyroid drug (ATD) resistant thyrotoxicosis raises difficult management issues. We describe three recent cases of apparent refractory thyrotoxicosis.Case 1: A 31 year old woman presented in July 2003 with thyrotoxicosis. Despite treatment with carbimazole (CBZ) 20 milligrams tds, serum free thyroxine (FT4) concentrations remained around 60 picomoles per litre (11-20). In October, CBZ dose was increased to 40 milligrams bd and dexamethasone 2 milligra...

We report two ladies who presented with thyroid dysfunction associated with neck swelling. In both cases within ten days of consultation they developed rapid enlargement of their mass associated with marked swelling of an arm.Case 1. A 63 year old lady developed sudden onset of a thyroid swelling associated with a new diagnosis of primary hypothyroidism . She had lost weight and felt tired. On examination she had a moderately enlarged woody goitre, there was no associated ...

The pattern of food consumption has a profound influence on metabolic hormone secretion, but until recently only crude manipulations of feeding events have been possible in rodents. Using a CLAMS-based system to overcome this problem, we have investigated the effect of 3 weeks of grazing (consumption of 1/24th of the total daily food intake of ad libitum-fed controls every 30 min during the dark phase (18.00–06.00 h)) and meal feeding (three 1-h periods of ad...

Background: It is generally accepted that a post-operative cortisol of <50 nmol/l is a good predictor of long-term remission following trans-sphenoidal surgery (TSS).Aim: We wished to determine the rate of late recurrence and need for consequent intervention in patients who had initial biochemical remission after TSS for pituitary dependent Cushing’s.Methods: We performed a retrospective analysis of our patients who underw...

Objective: Neonatal diabetes is caused by single gene mutations reducing pancreatic β-cell number or impairing β-cell function. Understanding the genetic underpinnings of rare diabetes subtypes highlights fundamental biological processes in β-cells. Our aim was to explore the genetic basis of a syndrome characterized by neonatal diabetes, microcephaly and epilepsy.Methods: We performed whole genome sequencing for 2 unrelated patients with ...
