Hydrocortisone treatment in septic shock promotes shock reversal and reduces mortality. We hypothesised the doses that used (200–300 mg/2 h) would result in plasma cortisol levels sufficient to saturate the 11 beta-hydroxysteroid dehydrogenase 2 enzyme (11 beta-HSD 2) with cortisol inactivation overload. Consequently cortisol would access the mineralocorticoid receptor producing mineralocorticoid effects. Hypertensive metabolic alkalotic effects would tend to counteract t...

Insulin resistance has been suggested to have a pathogenic role in polycystic ovary syndrome (PCOS). The use of insulin sensitising drugs might therefore have a therapeutic role in its management.We studied 20 patients (mean age 32.6 years) with PCOS (diagnosed by the Rotterdam Consensus Workshop group criteria, 2003) before and after treatment with metformin (1.5–3 grams daily) for 6 to 12 months.Clinical features studied wer...

Hyperandrogenism of adrenal origin evidenced by elevated dehydroepiandrosterone sulphate (DHEAS) levels has been reported in 20% to 30% of patients with polycystic ovary syndrome.We studied 50 patients with PCOS (defined by the Rotterdam Consensus Workshop group criteria, 2003). Adrenal hyperandrogenaemia was defined as a DHEAS level> 10.5 micromoles/litre was found in 10 patients (20%). Clinical features studied were body mass index (BMI) and hirsut...

Cushing’s syndrome is a rare endocrine disorder which the Royal College of Physicians/Society for Endocrinology Guidelines – Pituitary Tumours (1997) suggest should only be differentially diagnosed in centres with appropriate technical and enocrinological expertise. We conducted an audit against these guidelines of the management of Cushing’s syndrome in our unit (population covered 250, 000) over the 3-year period between January 2003 and January 2006. Aetiolog...
