Conn’s syndrome is an important endocrine cause for secondary hypertension. Hypokalaemia paralysis and rhabdomyolysis with accelerated hypertension may be the presenting symptoms of Conn’s syndrome. Here, we present one such case of a 38-year-old woman presenting with accelerated hypertension and acute onset quadriplegia. On biochemical evaluation, she was found to have severe hypokalaemia, metabolic alkalosis and elevated creatinine phosphokinase. Further evaluation revealed an elevated aldosterone renin ratio suggestive of primary hyperaldosteronism which was localised to left adrenal adenoma on contrast-enhanced CT. Patient’s blood pressure and serum potassium levels normalised after resection of the adrenal adenoma.

Neonatal Graves’ is uncommon, but a potentially fatal condition caused by transplacental transfer of thyroid stimulating immunoglobulin (TSI). It is seen in 1%–5% of infants born to a mother with Graves’ disease. Here, we report a unique case of transient neonatal thyrotoxicosis with positive TSI in a premature neonate born to the mother with primary hypothyroidism. A short course of antithyroid drug treatment leads to significant clinical and biochemical improvement followed by complete recovery.

Insulin autoimmune syndrome (IAS) is a rare cause of hypoglycaemia, characterised by recurrent hypoglycaemic episodes secondary to insulin autoantibodies in individuals who are not exposed to exogenous insulin. We are reporting a case of IAS in a 64-year-old gentleman, who presented with predominant postprandial hypoglycaemic episodes. On biochemical evaluation, he was found to have hyperinsulinemic hypoglycaemia. Localisation studies with MRI abdomen and endoscopic ultrasound (EUS) were negative for pancreatic tumour. Tests sent for insulin antibody levels were elevated. The patient was treated with frequent meals, acarbose and glucocorticoids. Patient condition improved and did not experience hypoglycaemia on follow-up.
