Objectives: To examine the effect on weight change of diet/lifestyle advice to maintain/achieve a healthy weight in an unselected PCOS population.Methods: All overweight patients attending the Reproductive Endocrine clinic with PCOS are routinely given lifestyle advice for weight loss by their consultant, offered referral to see a dietician and, when clinically appropriate, prescribed orlistat. Clinical notes were reviewed for 50 consecutive patients wit...

Introduction: There has been an increasing trend towards outpatient and short stay surgery in UK in last 20 years. This leads to reduced costs, reduced inpatient waiting lists, increased availability of inpatient beds and has the psychological benefit of avoiding prolonged hospitalisation.We liked to evaluate the feasibility of day case and short stay surgery for parathyroid disease in our district general hospital.Material and method: It was retrospecti...

Introduction: Tc 99m sestamibi scan and ultrasound are been used most frequently than other imaging technique in the pre operative localization of parathyroid gland in primary hyperparathyroidism. We liked to evaluate our hospital experience with the scan in preoperative localization of the glandular disease.Method and material: It was a retrospective audit of 7 years from 2000–2007 of 48 patient who underwent open explorative procedure by single su...

The most robust biochemical marker for the diagnosis of PCOS is hyperandrogenism (androstenedione, testosterone), thought to originate from the ovaries and/or adrenals. However the change in circulating androgen/LH ratios with increasing body mass in women with PCOS suggests the autocrine generation of androgens within adipose tissue itself. The enzyme 17beta hydroxysteroid dehydrogenase (17betaHSD) which has seven human isoforms is an important regulator of sex steroid metabo...

Central obesity is associated with increased morbidity and mortality. Pre-adipocyte proliferation and differentiation contribute to increases in adipose tissue mass, yet the mechanisms that underpin these processes remain unclear. Patients with glucocorticoid excess develop central obesity, but circulating cortisol levels in idiopathic obesity are normal. The enzyme 11 beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) converts inactive cortisone (E) to active cortisol (F)...

Maternal hypothyroidism disrupts fetal brain development in the rat; affected parameters include several neuron-specific cytoskeletal proteins and neurotransmitter metabolic enzymes. The aim of this study was to determine whether maternal hyperthyroidism also impacts upon fetal neuronal development.Partially thyroidectomised rat dams were subcutaneously implanted with osmotic pumps to infuse either 1.5 micrograms thyroxine/100 g body weight/day (HYPER) o...

Introduction: Incompletely controlled acromegaly has a three-fold excess all-cause mortality, with stroke being the predominant cause of death. Debate exists about the relationship between fractionated radiation (FRT) and risk of stroke, with radiation damage to cerebral vasculature potentially being a cause. We present outcomes in patients treated by gamma knife STRS at the National Centre for Stereotactic Radiosurgery in Sheffield, with...

Background: Tuberculosis (TB) is an important cause of mortality and morbidity globally. Only a small proportion cases of systemic TB present with lesions spreading to meninges, sella, or ventricles. Cases of intra-sellar pituitary adenoma secondary to TB have been rarely identified, often with uncertainty on medical management as opposed to more aggressive surgical therapy. We report an interesting case of pituitary adenoma presenting with pan-hypopituitarism and posterior pi...

Spindle cell oncocytoma (SCO) is a rare nonfunctioning neoplasm of the anterior pituitary gland .This tumour is often misdiagnosed as pituitary adenoma or pituitcytoma due to it’s location and symptoms. Such tumours are highly vascular radiologically and histologically. We report a 54 year old gentleman who was found to have pituitary adenoma on CT head performed after a fall. Subsequent Pituitary MRI showed 25×18 mm pituitary macroadenoma with optic chiasm compressi...
