Rationale and aim: The incidence of intracranial aneurysms (IA) appears increased in patients with PAs/PitNETs. Changes in hemodynamics and vascular structure secondary to mass effect, inflammation, and hormonal changes (primarily, GH hypersecretion) have been suggested as risk factors. Study aim was to define typical features, timing of occurrence and treatment, and identify risk factors in patients with PA/PitNET and IA.Patients and methods: Data of 57...

Background: Diabetes insipidus (DI) is a recognised complication of pituitary surgery, with current diagnosis requiring clinical observation aided by plasma and urine electrolytes and osmolalities. Copeptin, a 39 amino acid glycopeptide secreted in equimolar quantities to ADH, is a stable surrogate marker of ADH release and has potential to facilitate prompt diagnosis of post-operative DI. This assay has been shown to accurately predict which patients are likely to develop DI ...

Spontaneous pregnancy (SP) in TS is rare (4.8–7.6%). Oocyte-donation-in-vitro-fertilization (IVF-OD) and fertility-preservation increasingly offer the possibility of childbearing. Nevertheless, pregnancy is associated with an increased risk of complications. Adoption/surrogacy represents alternative parenting options.Aim: To analyse parenting options and pregnancy outcomes inTS.Methods: Data was collected in 154 TSwom...

Introduction: NICE recommends specific annual health checks for children and young people (CYP) with diabetes aged 12 years and over to check for health of feet, kidneys, thyroid and eyes in addition to BP, BMI and HbA1c. Historically, we included annual review care processes into regular diabetes multi-disciplinary clinics. In 2017, our service was identified as negative outlier in the National Paediatric Diabetes Audit for completion of health care processes. In particular, ...

Pituitary dysfunction is a common, treatable consequence of traumatic brain injury (TBI), and is associated with poorer outcomes. Identifying prognostic factors that allow targeted endocrine testing will ensure that patients at higher risk of pituitary dysfunction are identified and screened.Analysis of 176 adults at least 6 weeks after TBI attending the multidisciplinary Imperial TBI clinic found an overall prevalence of pituitary dysfunction of 13.7% (...

Introduction: Although it is well-known that serum testosterone (T) levels decrease in ageing men, to this date no longitudinal data are available on changes in T levels in healthy young adult men.Objective: To investigate age-related longitudinal changes in serum levels of total T, free T and sex hormone binding globulin (SHBG) in healthy young men.Methods: Data from 999 healthy men aged 24–46years who participated in a long...

We have previously reported that exercise at high altitude (HA) led to a significant increase in brain natriuretic peptide (BNP) levels. In contrast two other publications have reported no change in resting BNP at HA. We therefore measured BNP and Lake Louise (LL) Acute Mountain Sickness (AMS) scores in a further 20 subjects at rest in Kathmandu (Kat; 1300 m); and following exercise and at rest at 4270 m and 5150 m. Compared with the baseline BNP level at Kat (9.2+/−2 pg...

High altitude exposure leads to a marked natriuresis and diuresis facilitated by a reduced resting and subdued post-exercise aldosterone. There is a strong correlation between aldosterone and cortisol at high altitude and although most, but not all, investigators report a rise in cortisol with ascent very little data exist regarding the post-exercise response in cortisol. We therefore measured salivary cortisol in a cohort of 45 subjects post-exercise and 20 subjects at rest w...

Aim: To describe the prevalence and natural history of retinopathy in a cohort of children and young people with type 1 diabetes attending a tertiary hospital diabetes clinic.Methods: We analysed follow-up data from 2008 to 2010 on all children eligible for retinopathy screening using the ‘Twinkle’ diabetes database and the regional retinal screening database.Results: 88% (149/169) of eligible children were screened in 20...

Acute mountain sickness (AMS) is common at high altitude (HA) and is associated with a relative failure of the natriuresis and diuresis that occurs at HA. The role of brain natriuretic peptide (BNP) in this context has not been thoroughly investigated. We aimed to clarify if BNP rises in response to exercise at HA and if so whether this is related to markers of acclimatization. Thirty-two healthy subjects had assessments of BNP, aldosterone and markers of HA acclimatization (a...
