Objectives: To assess the physiological benefits and side effects of testosterone replacement therapy (TRT) in routine use.Methods: A search of a historic database of 427 men using TRT identified 135 men lost to follow-up, 19 men who had insufficient data and 273 current attendees who formed the study group. A retrospective review of clinical records focused on bone mineral density (BMD) as the beneficial outcome and raised haematocrit (HCT) and prostate...

The requirement for Sestimibi imaging of the parathyroid glands has increased over recent years, partly due to advances in surgical techniques and the need for accurate pre-operative localisation. We audited sestimibi imaging to ensure efficient and appropriate use of this tool in the face of increasing demand. Over two and a half years 128 scans were identified by Nuclear Medicine. We obtained biochemistry and operative status for these using the hospital patient administrati...

Aims: To assess factors associated with excess rates of fractures in women with Turner’s syndrome.Settings: Adult Turner Clinic.Outcome measures: Bone fracture history, oestrogen, growth hormone, oxandrolone and thyroxine therapies, anthropometry, calcium, vitamin D, parathyroid hormone and karyotype, hearing impairment, spinal bone mineral density (BMD). This study was approved by Ethical Committee.Resu...

Spironolactone (Sp) is an aldosterone-antagonist diuretic, that is traditionally used in the treatment of hirsutism due to its antiandrogenic effects. Sp can inhibit ovarian and adrenal biosynthesis of androgens, compete for the androgen receptor in the hair follicle, and directly inhibit 5alpha-reductase activity. The steroid suppressive effects are so variable that the receptor-blocking action is considered the most important mechanism. It is probable for this reason that co...

Congenital adrenal hyperplasia(CAH) and other disorders of adrenal steroid synthesis compromise synthesis of cortisol and aldosterone. Deficiency of 7-dehydrocholesterol-7-ene-reductase (DHCR7) in the Smith Lemli Opitz syndrome (SLOS) also affects cholesterol synthesis. New-born infants have dysmorphic facial features, microcephaly, second and third toe syndactyly and genital malformations. Later there is mental retardation and problems with cardiac and intestinal function thr...

Over a third of women with polycystic ovarian syndrome (PCOS) display glucose intolerance and multiple risk factors for cardiovascular disease, including central obesity. Interleukin-6, a cytokine that is mainly derived from adipose tissue, has recently been implicated as an important link in the development of cardiovascular disease in obesity. We determined the relations between circulating Interleukin-6 levels and anthropometric, metabolic and hormonal parameters in 38 wome...

IntroductionWomen with Turner Syndrome have an increased prevalence of hearing loss. Conductive hearing loss (CHL) is thought to be caused by craniofacial abnormalities or defective mucociliary transport resulting in impaired middle ear ventilation, increased otitis media and tympanic perforations. Sensorineural hearing loss (SNHL) progresses with age, possibly due to premature aging. An adult population was assessed for the impact of childhood treatment...

Introduction: Congenital adrenal hyperplasia (CAH) is characterised by impaired gluco and mineralocorticoid and excessive adrenal androgen secretion from the adrenal cortex. More than 90% of cases of CAH are caused by defects in the steroid 21-hydroxylase (CYP21) gene. We describe the association between salt-losing 21-hydroxylase deficiency and growth hormone deficiency.Patients and Methods: We reviewed 4 patients with salt-losing CAH (CYP21), who pres...

Cessation of hGH in GH deficient children generally occurs when final adult height has been obtained.Commonly, transition to adult clinics occurs in late teenage years,a time when patients are studying for A-levels, entering higher education or full time employment. It had been noticed that some patients were not doing as well in these areas as had been expected but that when adult hGH was commenced their performance improved.The aim of this audit was to try and investigate wh...
