35-year old female patient with bilateral pheochromocytoma and operated medullary carcinoma of thyroid gland (MEN II B sy.) is put in the octreotide therapy as she doesn’t accept operation as a therapy because of religious reasons (transfusion of blood) and attacks of artery hypertension couldn’t be control with alfa-adrenergic receptors antagonists.12 MONTH 2004 ADRENALIN-urine 890 nmoldU/l (10.2–65.5); NORADRENALIN-urine >5000...

MEN 1 is an autosomal dominant syndrome associated with benign and malignant neuroendocrine neoplasia. It is characterised by primary hyperparathyroidism, pituitary neoplasia and foregut lineage neuroendocrine tumours. It has also been associated with premature cardiovascular death. Since diabetes is associated with an increased risk of cardiovascular mortality we investigated the prevalence of diabetes (DM) and impaired fasting glucose (IFG) in a large cohort of patients with...

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...

A 35 year old woman presented with severe bone pain, body aches, progressive deformities of chest, skull and swelling of hands for two years. Past history included bilateral total hip replacement for fracture of neck of femur one year back. She was normotensive and normo-glycemic. Her dietary consumption of calcium and vitamin D and sun-exposure was adequate. Investigation revealed haemoglobin 5.4gram per deciliter. Serum calcium and serum iPTH levels were elevated at 3.6milim...

Hypothalamo-pituitary-adrenal (HPA) axis responses to stress are attenuated perinatally in mother rodents. We have now investigated the peripheral sympathetic and adrenal medulla responses to stress in pregnancy by measuring noradrenaline and adrenaline secretion after stress. Virgin and pregnant rats were blood sampled before and after exposure to airpuff startle stress in their home cages, and samples analysed for adrenaline, noradrenaline and ACTH concentration by RIA. Airp...

VA Thornton-Jones, JAH Wass and HE Turner, OBJECTIVE: Despite a recommended injection frequency of 4 weekly(4w), prolonged duration of GH suppression has been observed in some patients following treatment with long-acting somatostatin analogues. The aim of our study was to perform a prospective systematic study to determine whether extending the interval between doses of Octreotide LAR (LAR) allows maintenance of 'safe' GH in selected patients with acromegaly.<p class="abs...

Ligand-activated peroxisome proliferator-activated receptor gamma (PPARgamma), a nuclear hormone receptor, dimerises with retinoid X receptor(RXR) and acts as a transcription factor translating nutritional, pharmacological and metabolic stimuli into changes in gene expression. PPARgamma is thought to serve several roles in adipocyte differentiation, fatty acid and lipid metabolism, insulin sensitivity and ovarian steroidogenesis. PPARgamma has also been shown to increase gluco...

Macroprolactin is a high molecular weight IgG-prolactin complex which has reduced bioactivity. Macroprolactinaemia is a relatively common phenomenon, accounting for upto 20% of cases of hyperprolactinaemia in clinical practice; in the absence of amenorrhoea or hypogonadism these patients do not usually need dopamine agonist therapy. To ensure appropriate detection and management of such patients we routinely screen all serum samples with hyperprolactinaemia (>600 mU/l) for ...

Background: Community based surveys have revealed that approximately 20% of patients taking thyroxine have low serum TSH concentrations. Likewise, a high proportion of patients (27%) have been found to have high TSH concentrations. Suboptimal thyroxine treatment, in particular overtreatment, is associated with significant potential health risks including atrial fibrillation and osteoporosis. In Sheffield, thyroxine treated patients are routinely enrolled on a computerised thyr...

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...
