Parental Gonadal Mosaicism for a BRAF Mutation in Cardiofaciocutaneous Syndrome

Geoghegan Sarah , Morrissey Rose , Shorto Jeniffer , Ramsden Simon , O'Riordan Stephen , Green Andrew , O'Connell Susan

Background: Cardiofaciocutaneous syndrome (CFCS) is a rare autosomal dominant (AD) condition characterized by cardiac abnormalities, a distinctive craniofacial appearance and short stature. Endocrine manifestations include GH deficiency and precocious puberty. CFCS is part of the RASopathy group including Noonan, LEOPARD, and Costello syndromes. The four associated genes are BRAF (~75%), MAP2K1 and MAP2K2 (~25%), and KRAS (<2%). Most individuals represent new sporadic muta...

Xanthogranulomatous Hypophysitis: a Rare but Mistaken Pituitary Lesion

Kothandapani Jaya Sujatha Gopal , Bagga Veejay , Wharton Stephen , Sinha Saurabh , Dimitri Paul

Introduction: Xanthogranulomatous hypophysitis (XGH) is a very rare form of pituitary hypophysitis that may present both clinically and radiologically as a neoplastic lesion or craniopharyngioma. Our case series compares the paediatric and adult presentations of XGH and the differential diagnoses considered.Case series: Patient 1: A 15-year-old female presented with refractory headache, lethargy, short stature, delayed growth (weight (−3.3...

Psychosocial Screening in Children with Type 1 Diabetes in Ireland

Hennessy Elena , Gallagher Patricia , Butler Triona , O'Toole Norma , O'Connell Susan M , O'Riordan Stephen M P

Background: Psychosocial factors may be fundamental explaining poor glycaemic control in children with type 1 diabetes (T1DM). Anxiety, depression are well described in children with T1DM. According to Kauffman (2012), diabetes management can only be successful if psychosocial needs are assessed and addressed.Objective and hypotheses: To examine the association between glycaemic control and scores on two screening tools measuring psychosocial risk and em...

Prevalence of Vascular Complications in Children with Type 1 Diabetes in Ireland

Butler Triona , Hennessy Elena , Gallagher Patricia , O'Toole Norma , O'Connell Susan M , O'Riordan Stephen M P

Background: Screening guidelines for vascular complications in children with type 1 diabetes (T1DM) are based on results from Diabetes Control and Complications Trial (DCCT) and its follow-up, the Epidemiology of Diabetes Interventions and Complications (EDIC) trial. These studies established conclusively that early and intensive diabetes care improves long-term outcomes.Objective and hypotheses: To establish screening practices and prevalence of vascula...

A Selective Nonpeptide Somatostatin Receptor 5 (SST5) Agonist Effectively Decreases Insulin Secretion in a KATPHI Mouse Model and in Human HI Islets

Juliana Christine , Chai Jinghua , Arroyo Pablo , Rico-Bautista Elizabeth , Betz Stephen , De Leon Diva ,

Inactivating mutations of ß-cell KATP channels cause the most common and severe form of congenital hyperinsulinism (HI), a ß-cell disorder that results in dysregulated insulin secretion and persistent hypoglycemia. Children with KATPHI are typically unresponsive to diazoxide, the only FDA-approved drug for HI. Octreotide, an SST2-selective agonist peptide that inhibits insulin secretion, is used as second line therapy, but poor efficacy and SST2...

A novel case of hypoglycaemia secondary to a pro-insulin processing disorder

Amin Nadia , Wark Gwen , Church David , Burling Keith , Barker Peter , Williams Gemma , O'Rahilly Stephen

Background: Hypoglycaemia in patients with a high concentration of insulin and low concentration of C-peptide can be secondary to administration of exogenous insulin. This often results in safeguarding measures, with significant consequences for the patient and family. We report a novel case of a patient with symptomatic hypoglycaemia. Initial results suggested high insulin and low C-peptide levels, but subsequent testing revealed a pro-insulin processing diso...

Improved Health-related Quality of Life with Insulin Therapy in Children with Cystic Fibrosis-related Diabetes: a Prospective Cohort Study

George Sherly , Hoey Hilary M C V , Costigan Colm , Murphy Nuala , Roche Edna F , O'Riordan Stephen M P

Background: Cystic fibrosis-related diabetes (CFRD) is a common complication in cystic fibrosis (CF). CFRD symptoms and treatment may impose additional burden and adversely affect their QoL.Objective and hypotheses: Assess HRQoL in CF children with normal glycaemia (CFN) and CFRD and evaluate the change in HRQoL over 1 year period along with clinical changes.Method: A prospective study was undertaken including children aged 10&#150...

Increasing Testicular Size due to Bilateral Large Cell Calcifying Sertoli Cell Tumours in a Peri-Pubertal Child with Carney Complex

Geoghegan Sarah , Morrissey Rose , Moore Michael , O'Sullivan M , Murphy Michelle , Irvine Alan , O'Riordan Stephen , Quinn Fergal , O'Connell Susan

Background: Carney complex (CNC) is a rare multi endocrine neoplasia syndrome associated with endocrine and non-endocrine tumours. Three types of testicular tumour have been described; large cell calcifying Sertoli tumours (LCCST), Leydig cell tumours and testicular tumours of adrenal origin. LCCST is a rare benign stromal tumour, which has been observed in 41% of males affected with CNC, usually appearing in the first decade of life. It can be hormonally active, presenting wi...

Novel Molecular Mechanisms of Congenital Hyperinsulinism due to Autosomal Dominant Mutations in ABCC8

Nessa Azizun , Aziz Qadeer , Thomas Alison , Harmer Stephen , Flanagan Sarah , Ellard Sian , Kapoor Ritika , Tinker Andrew , Hussain Khalid

Background: Dominant mutations in ABCC8 can cause congenital hyperinsulinism (CHI), which is characterised by unregulated insulin secretion.Objective and hypotheses: To understand the molecular basis of medically unresponsive CHI due to dominant ABCC8 mutations.Method: We investigated ten patients with diazoxide unresponsive CHI who required a near total pancreatectomy. DNA sequencing revealed seven dominant heter...

Describing the Natural History of Clinical, Biochemical and Radiological outcomes of children with Familial Partial Lipodystrophy type 2 (FPLD2) attending a National Service for Severe Insulin Resistance: a Retrospective Cohort Study

Xuan Zhong Zhu , Stears Anna , Harris Julie , Wilber Ellen , Savage David , O’Rahilly Stephen , Williams Rachel ,

Background: FPLD2 results from autosomal dominant mutations in the LMNA gene. The physical appearance develops through adolescence where subcutaneous fat deposits of the limbs, trunk, buttocks and legs do not develop resulting in a muscular appearance. The metabolic phenotype includes elevations in triglyceride concentrations and hepatosteatosis with resultant insulin resistance. Co-morbidities that may manifest during young adulthood include early-onset diabe...
