Introduction: The association between fatigue, functional status and subclinical hypothyroidism (SCH) remains unclear. The available data is not consistent, and this is likely to be due to selection bias in studies recruiting patients from clinic rather than unselected community populations. Only population surveys looking at prevalence of fatigue and functional status in SCH are likely to provide the answer.Objective and Methodology: We compared the pre...

Glucocorticoid (GC) excess adversely affects many aspects of skin homeostasis, characteristics of which are also seen during ageing (e.g. poor wound healing). The mechanisms underlying this remain unclear. The enzyme 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) regenerates cortisol, independently of circulating concentrations, and we have previously demonstrated increased 11β-HSD1 expression in human dermal fibroblasts (HDF) from aged donors. We have now e...

Background: Male hypogonadotrophic hypogonadism is an increasingly common cause of referral to endocrine clinics. Subnormal testosterone levels are frequently observed in obesity, type 2 diabetes mellitus and in the elderly. Endocrine Society guidelines suggest stratification of investigations based on the degree of androgen deficiency, with full pituitary function testing and MRI recommended only in those with serum testosterone levels less than 5.2 nmol/L. However the eviden...

Concerns have been raised that undergraduate medical education in Endocrinology/Diabetes (E&D) is not preparing students adequately for clinical practice. This project assessed trainer perceptions of the delivered D&E curriculum and identified areas for improvement. We surveyed E&D consultants at the 12 hospitals which accept students from our medical school using an online questionnaire. Emails were sent to 50 consultants. The response rate was 46% (23/50 recipien...

The guidelines for the treatment of pituitary apoplexy have now been published in Clinical Endocrinology (Clin Endocrinol 2011 Jan;74(1):9–20). These resulted from a group set up during the London pituitary multidisciplinary meeting.Classical pituitary apoplexy is a medical emergency and rapid replacement with hydrocortisone maybe life saving. It is a clinical syndrome characterised by the sudden onset of headache, vomiting, visual imp...

We recently showed that 5α-reduced metabolites of corticosterone (B), namely 5α-dihydrocorticosterone (5αDHB) and 5α-tetrahydrocorticosterone (5αTHB), possess similar anti-inflammatory properties to B, but have lesser metabolic effects. Here, we explored the anti-inflammatory mechanisms of these 5α-reduced metabolites in vitro. Data are mean % suppression/induction, compared by one way ANOVA, *P<0.05 versus vehicle.<p class="...

Background: Thyroid hormones (TH) are vital for fetal and placental development. TH transporters including monocarboxylate transporters 8 and 10 (MCT8, MCT10), organic anion transporters (OATP1A2, OATP4A1) and system-L amino acid transporters (LAT1, LAT2) are expressed in human placenta from 6 weeks of gestation. All of these TH transporters have been localized to the human syncytiotrophoblast layer of placental villi, which is in direct contact with maternal bl...

Aim: To assess the impact of acromegaly on quality of life (QoL) as evaluated by the acromegaly QoL (AcroQoL) questionnaire in Maltese patients with cured, controlled and uncontrolled acromegaly.Design: Cross-sectional survey study.Methods: The AcroQol questionnaire was completed by all patients during their routine outpatient visit. Clinical and hormonal data including GH and IGF1 levels were also taken at the time of survey.<...

Primary hyperaldosteronism usually results from an aldosterone-secreting adenoma of the adrenal cortex (Conn’s adenoma) or bilateral adrenal hyperplasia. Identification of the anatomical adrenal lesion causing hyperaldosteronism typically involves CT or MR scanning, with lateralisation of aldosterone production confirmed by adrenal vein sampling (AVS). The latter is a technically difficult and invasive procedure, but current non-invasive alternatives (e.g. radiolabelled i...

A 24-year-old Asian lady with no past medical history was admitted under the surgical team with right sided abdominal pain, nausea and vomiting, postural dizziness and weight loss. She was give trimethoprim for a possible urinary tract infection along with paracetamol, tramadol and diclofenac. Blood tests on admission demonstrated normal renal, liver and thyroid function, a normal C-reactive protein and full blood count and a low sodium of 131 mmol/l. An abdominal ultrasound w...
