It is known that a subset of obese individuals do not exhibit features of the metabolic syndrome (Met-S); these are referred to as being metabolically healthy obese (MHO) individuals. Conversely there are other individuals who although have a normal BMI are insulin resistant and exhibit some of the features of the Met-S and are termed as being metabolically unhealthy normal weight (MUHNW) individuals. This study aims to identify the prevalence of metabolic health among a diffe...

Background: Hypogonadism in males is associated with a reduction in bone mineral density (BMD). It is known that the reversal of this is achievable through adequate hormone replacement; however, the degree to which this is dependent on the proportion of time patients spend within the recommended therapeutic range (>15 nmol/l) in real-ife has not yet been established.Aim: To evaluate the degree to which the proportion of time that a hypogonadal p...

Background: With the increasing prevalence of obesity and related morbidity including glucose intolerance in childhood, there remains a dispute about the best screening test to identify this early. The aim of our study was to determine the prevalence of impaired glucose tolerance (IGT)/type 2 diabetes mellitus (T2DM) in a multiethnic cohort of 100 overweight/obese children and adolescents in our clinic and compare the results of the screening tests.Study...

Background/aims: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women, being characterized by ovarian hyperandrogenism attributed to intrinsic overproduction by theca cells (TCs). Although previous reports pointed a higher stability and transcription of CYP17mRNA (Wickenheisser JK et al. 2006)1, few have examined (and none has quantified) P450c17 protein expression in TCs from PCOS ovaries. Therefore, the aim of this study is to qua...

We present a case of a 29-year-old lady who presented with subfertility. She had had a 2 years history of oligomenorrhoea with highly irregular menses. She had symptoms of depression and described tunnel vision. Clinically, she was euendocrine with no features of hormonal excess or deficiency. She was not hirsute. Visual field testing demonstrated a severe left superior temporal quadrantopia.Laboratory investigations demonstrated an oestriadol level rang...

A 37-year old woman developed grand-mal seizures shortly after having given vaginal birth at term. Three hours later, her newborn son also had a tonic-clonic seizure. Following the convulsions, maternal fractures of the humerus and the neck of femur were detected.The pregnancy had been uneventful except for hip pains for 4 weeks prior to delivery. For years, the patient had been ingesting 5 l of bottled water daily. Labour had set in spontaneously and sh...

Context: Exogenous oestrogen administration causes prolactinoma formation in rats and there are anecdotal reports of oestrogen treatment and prolactinoma formation in gender reassignment males to females. It remains unclear whether chronic exposure to high dose oestrogen in women is linked with prolactinoma development.Aim: The aim of this study was to determine the effect of high dose subcutaneous estrogen on prolactin and gonadotrophin levels of 101 wo...

Introduction: Recent trials suggest that using ergot-derived dopamine agonists such as cabergoline in the treatment of Parkinson’s disease is associated with an increased risk of valvular heart disease. However, the dose of cabergoline used to treat hyperprolactinaemia is considerably less than that used in Parkinson’s disease.Study design: A cross-sectional study; forty four patients, who received cabergoline for at least 6 months, underwent t...

Context: We have previously demonstrated that, in cranially irradiated patients with normal peak GH responses to both the insulin tolerance test (ITT) and the growth hormone-releasing hormone plus arginine stimulation test (GHRH+AST), somatotroph reserve can be substantially reduced, while individual and overall spontaneous GH secretion remain entirely normal due presumably to a compensatory increase in hypothalamic stimulatory input within a partially damaged hypothalamic pit...

Background: Polycystic ovary syndrome (PCOS) is common with a suggested prevalence of 6–7% in Caucasian women of reproductive age. The presence of cardiovascular risk factors of obesity, insulin resistance and dyslipidaemia may predispose women with PCOS to coronary heart disease, although this remains controversial. This study aimed to contrast and compare the changes in lipid profile and hs-CRP following treatment with metformin, orlistat and pioglitazone in women with ...
