A previously well 55 year old man presented to his family practitioner with asix week history of dyspepsia. He denied any other symptoms including no weight loss. Clinical examination was normal.A gastroscopy was organised which revealed a 10 millimetre sessile polyp located at greater curvature at the lower body of the stomach. The polyp was removed by snaring. Histological examination of the polyp revealed heterotopic pancreatic ...

A 55 year old lady was referred by her general practioner with a six months history of generalised lethargy and cold intolerance.This was associated with abdominal bloating and constipation.She had been more irritable recently and was getting depressed. She also described symptoms suggestive of carpal tunnel syndrome. The only past history of note was of lactose intolerance.There was no family history of thyroid disorder.On examination she was clinically...

Background: Low testosterone levels are a common finding in men with type 2 diabetes and are also associated with low HDL cholesterol (HDL-C) levels which are an independent risk factor for cardiovascular disease. The androgen receptor CAG repeat polymorphism (AR CAG) and GGN repeat polymorphism (AR GGN) affect receptor function such that shorter AR CAG and AR GGN=23 are associated with greater transcriptional activity in vitro.Methods and results...

Serum testosterone level is known to inversely correlate with insulin sensitivity and obesity in men. Furthermore, there is evidence to suggest that testosterone replacement therapy reduces insulin resistance and visceral adiposity in Type 2 diabetic men. Adipocytokines are hormones secreted by adipose tissue and contribute to insulin resistance. We report a double-blind placebo controlled crossover study in 20 hypogonadal Type 2 diabetic men examining the effect of testostero...

Type 2 diabetes mellitus is associated with increased prevalence of low serum testosterone levels in men [1]. Testosterone levels in men are known to be positively correlated with insulin sensitivity and negatively with visceral obesity. We performed a double blind placebo controlled crossover study to determine the effect of testosterone treatment on insulin resistance and glycaemic control in 24 hypogonadal men (10 patients treated with insulin) above age of 30 with Type 2 d...

Type 2 diabetes mellitus is associated with increased incidence of low serum testosterone levels in men. Testosterone is known to be positively correlated with insulin sensitivity. Rosiglitazone is an insulin sensitizing agent that reduces insulin resistance by binding to PPAR gamma receptor. The purpose of this study was to determine the effect of Rosiglitazone on testosterone levels in hypogonadal men with Type 2 diabetes.This study was approved by BDG...

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...

Low serum testosterone levels in men predict the future development of insulin resistance and Type 2 diabetes. Furthermore, men with Type 2 diabetes have lower testosterone levels than nondiabetic men. Testosterone is known to be positively correlated with insulin sensitivity. It has also been demonstrated that low levels of circulating androgens are associated with coronary artery disease, dyslipidaemia, hypertension and visceral obesity. The purpose of this study was to dete...

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 ...
