Fifty patients (male:female 23:27) with a phaeochromocytoma or paraganglionoma have been seen within the Oxford hospitals since 1985. Further information has been located on 48. Patients had a median age of 42.6 years (range 19.4-74.6) and a median follow up of 13.9 months postoperatively (range 0.6-146.3). The adenoma was unilateral in 44 cases (88%, left 20, right 22) and bilateral in 4 cases (8% 2 Von Hippel-Lindau disease (VHL) 1 Neurofibromatosis type 1 (NF1) 1 Sporadic)....

Background: We present a case of a 10 year old female with T1DM, referred to our tertiary centre for complex diabetes care due to her other severe chronic dermatological condition. We discuss the difficulties with optimizing diabetes control in such a chronic debilitating condition which has a pervasive effect on T1DM treatment.Case: To our knowledge this is only the second reported case of a child with T1DM and Epidermolysis Bullosa. Severe Recessive Dy...

Introduction: The impact of ethnicity and socioeconomic status (SES) on glycaemic control in children with type 1 diabetes (T1D) is poorly understood in England and Wales.Methods: We studied 18 478 children and young people with T1D aged <19 years attending diabetes clinics in England and Wales and included in the 2012–2013 National Paediatric Diabetes Audit (NPDA). Self-identified ethnicity was categorized as white, Asian, black, mixed, other a...

An estimated 5% of all newborns are born SGA (weight less than −2SD at birth), with 10% failing to catch up and becoming eligible for GH treatment. Not all children respond to GH, but the criteria for determining a non-responder have not been clearly defined. We have therefore evaluated first year growth performance of short SGA children treated with GH in The Growth Clinic, Manchester. Clinical and auxological data were collected retrospectively from the case records of...

Background: A polymorphism of the GHR gene, deletion of exon 3 (d3 GHR), has been associated with improved growth response to GH in some studies. We investigated the effect of this polymorphism across several diagnoses, evaluating parameters of growth outcome from a single institution (Manchester) and combined these with those derived from the literature using meta-analytical approaches.Methods: GHR genotype was assessed by PCR and related to clinical an...

Objectives: Current provocative tests for GH deficiency (GHD) are neither 100% sensitive nor specific. GH neurosecretory dysfunction (NSD) refers to the presence of growth failure, normal stimulated GH responses, but impaired spontaneous GH secretion. We describe our experience in managing GHNSD over 7 years.Methods: We retrospectively reviewed a cohort of 106 children admitted for 12-h overnight GH profiles (with 20-min sampling) between 2010 and 2016. ...

Background: Klinefelter syndrome (KS) is the commonest sex chromosomal disorder. Characteristic features include male phenotype with hypogonadism and progressive testicular failure, gynaecomastia and learning difficulties. The association between mediastinal germ cell tumours (GCT-M) and KS is well established, with KS occurring in 20% of GCT-M patients and the reported incidence of GCT-M in KS being 1.5 per 1000 (Nichols, 1991). Genital anomalies are also known to be rarely o...

CHI is a disorder of dysregulated insulin release characterised by severe recurrent hypoglycaemia. Mutations in genes encoding the beta-cell sulphonylurea receptor (ABCC8) and inward-rectifying potassium-channel (KCNJ11) are the commonest genetic cause of CHI, followed by that encoding glutamate dehydrogenase (GLUD-1). Histologically, disease pathology is subdivided into diffuse or focal disease; the latter associated with paternal mutations and somatic lo...
