Background: Gonadotroph adenomas are the most common non-functioning pituitary adenomas in adult1, 2. However, functioning gonadotrophinomas are rare. Here, we describe an unusual presentation of concurrent acromegaly and functioning FSHoma (FSH-secreting pituitary adenoma).A 39-year-old man presented with a vague visual disturbance to the optometrist and a bitemporal hemianopia was detected.Further questioning elicited ...

There are controversial data on the beneficial/detrimental effects on the cardiovascular as well as on the metabolic system by the sex hormone testosterone. Recent data support the hypothesis that low levels of androgens are associated with adverse cardiovascular risk factors including an atherogenic lipid profile, obesity, insulin resistance and hypertension. AMPK is a sensor of energy balance at both the cellular and whole-body level. Once activated by low energy status, it ...

Research indicates that low testosterone is associated with CAD in men. Evidence suggests that men with hypotestosteronemia and concomitant CAD may benefit from physiological testosterone replacement therapy (PTRT). The mechanism by which testosterone produces these cardio-protective effects and the role of the androgen receptor remains largely unknown. The aim of this study was to determine whether testosterone modulates atheroma formation via its classical signalling pathway...

Recent data suggest that critically-ill medical patients might not obtain as much benefit from insulin therapy as cardiothoracic patients. This may be because medical patients are more insulin resistant. We have investigated this in both groups.10 medical patients (age 67.0±4.4 y; 7M:3F, BMI 24.0±1.7 kg/m2; studied within 36 hours of admission to the ICU) and 7 post-operative cardiothoracic patients (age 71.4±3.8 y; 5M:2F, BMI 2...
