Introduction:Amiodarone is a life saving anti arrhythmic drug,but it has a complex side effect profile involving organs that include thyroid,lungs, liver and eyes. It is well known that patients on long term amiodarone therapy should be followed up in a structured manner including regular thyroid function tests,liver function tests,chest xray and eye examination.There are guidelines suggested by the Summary of Product Characteristics (SPC) for amiodarone...

Introduction: The combination of hypokalemia and hypercalcaemia is uncommon but potentially lethal. In primary hyperparthyroidism hypokalaemia most commonly occurs due to incomplete distal renal tubular acidosis. We present the first case of simultaneous primary hyperparathyroidism with Gitelman’s syndrome resulting in profound electrolyte imbalance.Case: A 48-year old man, referred with hypokalaemia (2.5 mmol/l) presented with a short history of ex...

Acromegaly and thyroid-associated ophthalmopathy(TAO) are uncommon diseases with different pathogenetic mechanisms.We report two patients with acromegaly and TAO and speculate on a possible association.A 54 year old man with subclinical hypothyroidism and strongly positive thyroid microsomal antibodies presented with features of TAO.MRI of his orbits confirmed the diagnosis.Clinical examination also revealed features suggestive of acromegaly,which was co...

INTRODUCTION:True hermaphroditism is rare but has been reported in more than 400 individuals.Thediagnosis requires the presence of both ovarian and testicular tissue in either the same or opposite gonads.The external genitalia may simulate those of either a male or a female or may be ambiguous.Diagnosis and treatment at an early age is important .CASE REPORT:A 14 years old phenotypic ma...

The porphyrias encompass a group of disorders characterized by inherited or acquired derangements in the biosynthesis of heme.Porphyria cutanea tarda is the most common form and is characterized by chronic skin lesions and hepatic disease.It may rarely be complicated by hepatocellular carcinoma. We present a 67 year old man who presented with hepatocellular carcinoma on a background of previous porphyria cutanea tarda.The patient was diagnosed with Type ...

Hypercalcaemia is a commonly encountered problem. Though primary hyperparathyroidism and malignancy account for greater than 90% of cases other rare causes need to be considered. We present an unusual but significant cause of hypercalcaemia.Of 87-year-old gentleman presented with acute abdominal pain and a severe hypercalcaemia with corrected serum calcium of 4.36 mmol/l (2.1–2.6). Significant dehydration was associated with acute renal failure (Tab...

Introduction: Non-Hodgkin’s lymphoma is an AIDS defining malignancy. However, a primary adrenal lymphoma as a presenting feature of HIV infection has not been previously reported.Case Report: A 66-year-old male presented with a short history of severe fatigue, weight loss, dizziness and nausea. Baseline blood results revealed normal biochemistry with mild normocytic anaemia, neutropaenia with lymphopaenia and the short synacthen test demonstrated in...

A 64-year-old lady presented with weight gain, tiredness, palpitations and tremor. She had no goitre and no other extra thyroidal manifestations. Both TSH and thyroid peroxidase antibodies (>1300) were elevated and she was treated by her GP with Thyroxine 50 mcg daily. She felt a lot worse on this, so it was discontinued and a full thyroid hormone profile was checked (see Table 1) which prompted referral; to Endocrinology.Other pituitary hormone leve...
