The current indication for TRT is hypogonadism, a syndrome complex combining hypogonadal symptoms and low testosterone concentrations. The optimal formulation for the treatment of hypogonadism is one that generates a physiological testosterone concentration in the age adjusted reference range, as well as the concentration of its metabolites oestradiol and dihydrotestosterone, while ideally mimicking the circadian rhythm in younger subjects. Optimal treatment should lead to cor...

Introduction: Hyponatraemia is the most common electrolyte abnormality encountered in hospitalised patients.Methods: This retrospective study included all inpatients with serum sodium ≤128 mmol/l at any point during their hospital stay between 1st March 2013 and 31st May 2013. Full review of medical case notes and laboratory results was undertaken in order to determine the comorbidities, drug history and aetiology of inpatients with hyponatraemia.<...

Introduction: Hyponatraemia is associated with increased inpatient mortality, but there is debate about whether hyponatraemia per se contributes to mortality or is merely an epiphenomenon of severe illness.Methods: This retrospective review of medical records included all inpatients with serum sodium (sNa)≤128 mmol/l who died at a teaching hospital over a 3-month period. The aim of this study was to examine the clinical course and the pote...

History: A 63 year old female presented with nausea, vomiting and loss of balance. She had no other symptoms. An MRI of the brain revealed a large incidental pituitary lesion occupying both the sella and suprasellar region, causing distortion of the optic chiasm and tracts. She had no headache, visual disturbance, tiredness, thirst or daytime frequency although she had long standing nocturia.Examination: Visual fields showed mild bitemporal desaturation ...

Case summary: A 55 year-old lady was referred by ophthalmology following diagnosis of bilateral central serous retinopathy, an accumulation of sub-retinal fluid at the fundus associated with Cushing’s syndrome. She also had proximal myopathy, bruising, centripetal weight gain and hypertension. Cushing’s was confirmed by 1 mg overnight DST (cortisol 581 nmol/L) and 48 hr-LDDST (407 nmol/L). 24 hr UFC was raised at 2666 nmol/L (12...

Introduction: Contrary to US guidelines, recent European guidelines do not recommend tolvaptan for the treatment of SIADH.Methods: Retrospective data collection of all inpatients treated with tolvaptan for SIADH in two UK hospitals between November 2010 and February 2014. All values were calculated as mean±S.D.Results: This case series included 61 patients (33 females, 28 males) aged 74.4±15.3 years with se...

Introduction: Hyponatraemia is the most common electrolyte disorder in hospitalised patients and is associated with significant morbidity and mortality.Methods: This retrospective study included all inpatients with serum sodium (sNa) ≤128 mmol/l at any point during hospitalisation at a teaching hospital over a 3-month period (1st March 2013 to 31st May 2013). Demographic, clinical and laboratory data obtained from patients’ case notes and labo...

Introduction: Hyponatraemia is a relatively common complication following pituitary surgery. However, there is sparse data about its optimal management and impact on clinical outcomes.Aims: To review the treatment and patient outcomes of hyponatraemia following pituitary surgery.Methods: A retrospective single-centre study included all inpatients who developed serum sodium (sNa) ≤ 132 mmol/l following pituitary surgery f...

Adrenal masses discovered incidentally during imaging (adrenal incidentalomas) are common and constitute a common reason for referral in the Endocrinology clinic. Our aim was to audit the prevalence of adrenal masses discovered in all computerised tomography (CT) abdominal imaging done over one calendar month in our centre. A secondary aim was to identify the underlying diagnosis and fate of the discovered adrenal nodules. All 690 CT scans done in March 2011 in our centre that...
