A case of de novo ABCC8 gene mutation resulting in Transient Neonatal Diabetes

Clemente Marisa Ferreira

Neonatal diabetes is characterised by hyperglycaemia in the first 6 months of life. Transient neonatal diabetes (TND) is differentiated from permanent neonatal diabetes by its remission in infancy/early childhood, with possible relapse during adolescence in 50% of the cases. Incidence of neonatal diabetes is thought to range from 1:90,000 to 1:160,000. A gene mutation affecting pancreatic beta cells synthesis/secretion of insulin is present in more than 80% of the cases. Overe...

Linking diabetes and severe cardiac malformations: a GATA6 mutation

Clemente Marisa , Weerasinghe Kamal

Introduction: GATA6 is a gene that encodes a zinc transcription factor with a key role in the development of several organ systems, as evidenced by the many congenital malformations that have been associated with its mutation. GATA6 plays a role in gut, lung, pituitary, and heart development, with broad expression in developing heart tissue and close link with pancreatic agenesis/hypoplasia. Most cases present with neonatal Diabetes, but a small proportion dev...

Brain-Lung-Thyroid Syndrome: differences in clinical spectrum in two case reviews

Clemente Marisa , Weerasinghe Kamal

Introduction: Brain-lung-thyroid syndrome (BLTS) is a rare autosomal dominant or de novo condition that occurs in early childhood, associated with mutations of the NKX2-1 (Thyroid transcription factor 1) gene present in chromosome 14q13. This protein plays a critical role during organogenesis of basal ganglia, lungs, including surfactant production and homeostasis, and thyroid. The clinical spectrum varies from the complete triad of brain-lung-thyroid...

A 1-year Follow-up Study to Evaluate Efficacy and Compliance of Continuous Glucose Monitoring in Children with Type 1 Diabetes Mellitus

Soni Astha , Clemente Marisa , Ng Sze May

Background: Self monitoring of blood glucose (SMBG) is an important part of diabetes management. Continuous glucose monitoring system (CGMS) provides the real time measurements of users’ glucose levels. The NICE guideline recommends use of CGMS if there is persistent hypoglycaemia unawareness or repeated hypoglycaemia or hyperglycaemia. In our paediatric diabetes clinic within a large DGH, we have a cohort of 12 children who were funded for the CGM use for a minimum of 1 ...

A rare case of thyroid dyshormonogenesis with high urine iodine excretion

Gunarathna Leslie , Clemente Marisa , Weerasinghe Kamal

Background: Variety of defective thyroid hormone biosynthesis accounts for 15% of congenital hypothyroidism. Children with IYD gene (formerly DEHALI) mutation, which encodes thyroidal enzyme iodotyrosine deiodinase, cannot recycle iodine in thyroid gland. This results in urinary loss of iodine and hypothyroidism. The condition may be missed by neonatal screening programs.Case description: A male baby was born of non-cons...

The complexity of Hyperinsulinism in newborns

Clemente Marisa , Crawley Louise , Weerasinghe Kamal

Background: Hyperinsulinism represents a group of clinically, genetically and morphologically heterogeneous disorders characterised by β-cell dysfunction in glucose homeostasis leading to excessive insulin secretion with profound and recurrent hypoglycaemia. In most countries it occurs in approximately 1/25,000 to 1/50,000 births. Mutations in at least 14 genes have been reported to cause congenital hyperinsulinism. In nearly half of the cases, cause rema...

Comparison Between Patients and Families who Routinely Download Data and Those who do Not Download Data at Home in The Management of Type 1 Diabetes

Ng Sze May , Sultana Perveen , Clemente Marisa , Apperley Louise

Background: In type 1 diabetes (T1D), optimal glycaemic control requires intensive self-management to reduce the risk of complications. While routine downloading and review of blood glucose data is part of clinical practice of healthcare providers in an outpatient setting, patients and families are also educated, advised and encouraged to regularly download and review blood glucose data at home in order to make adjustments to insulin dosing for carbohydrate in...
