A 19-year-old man was referred to Endocrinology Clinic with a minimally raised calcitonin level. He had a past history of primary hyperparathyroidism resulting in renal colic aged 17 years, and underwent three gland parathyroidectomy aged 18 years. Histology demonstrated a single right lower parathyroid adenoma with normal thyroid biopsy. He has no family history of endocrine disease and is a non-smoker. His calcium has remained normal since with detectable PTH. Over 5 years t...

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% (...

Background: Pituitary dysfunction is a recognised consequence of traumatic brain injury (TBI) causing significant cognitive, psychological and metabolic impairment. Hormone replacement offers an important therapeutic opportunity. Blast traumatic brain injury (bTBI) from improvised explosive devices (IEDs) is commonly seen in soldiers returning from recent conflicts. We investigated: i) the prevalence and consequences of pituitary dysfunction following moderate-severe bTBI, and...

Using functional MRI, we examined how regional brain activity varies with nutritional state when viewing food pictures of different caloric density and appeal.Eighteen non-obese healthy volunteers (BMI 22.2±0.5 kg/m2, age range 19–36 years, 8 male) were studied on 2 separate mornings after an overnight fast (mean±S.E.M. 15.5±0.3 h) or when fed (1.2±0.1 h after breakfast, food intake 45±4% of estimat...

Introduction: Non-syndromic pituitary gigantism can result from AIP mutations and the recently identified Xq26.3 microduplications causing X-LAG.Patients and methods: DNA samples and clinical data were collected from 151 patients with pituitary gigantism. All samples were tested for AIP mutations; AIP mutation negative cases (AIPneg) were screened for Xq26.3 microduplications.Results: Xq26.3 micr...
