Case presentation: We report on an Irish boy who presented aged 8 years old with an 18 month history of gradual right-sided gynaecomastia, which was surgically excised with good cosmetic outcome. He subsequently re-presented with left-sided breast tenderness and budding and was then referred to endocrinology. On review, his height was greater than the 99th centile, weight was on the 75th centile and bone age was advanced by 2 years and 9 months. Tanner staging...

Childhood-onset growth hormone deficiency (CO-GHD) is topical at present due to the increasing understanding of underlying genetic aetiologies, influence on childhood growth, and future effects on adolescence and adult health. There is no previous Irish data of this group of children.Methods: A retrospective cohort study over 2 years (2013-2015) including all children diagnosed with GHD who received recombinant growth hormone treatment (rGH). Predictors ...

Background: CO-GHD can be caused by a variety of aetiologies, including pituitary or brain structural abnormalities, and increasingly recognised genetic mutations of pituitary transcription factors. Idiopathic GHD is a diagnosis of exclusion. POU1FI is a late pituitary transcription factor. Mutations of POU1F1 have autosomal recessive (AR) inheritance, and phenotypically present with a normal or small anterior pituitary gland on magnetic resonance imaging (MRI), they are assoc...

Background: Childhood type 1 diabetes (T1DM) is associated with poor quality of life and significant family burden. Children, parents, extended family members and teachers were invited to a novel 2 day structured educational programme, ‘Pump SchooI’, delivered by a Consultant Led multidisciplinary team. Each Pump School included two age-matched children.Objective and hypotheses: To evaluate the effect of continuous s.c. insulin infusion (CSII) ...

Introduction: The influence of sex chromosomes and sex hormones on early human brain development is still poorly understood. Expression of Y chromosome genes may influence aspects of brain maturation in the 46,XY fetus, but the contribution of different Y genes is unknown. Furthermore, a marked increase in testicular testosterone biosynthesis/release from the testis occurs at around 8 weeks post conception (wpc) in the 46,XY fetus, but it is unclear whether te...

Introduction: Luscan-Lumish syndrome (LLS) is a postnatal overgrowth syndrome characterized by macrocephaly, mental retardation, seizures, postnatal overgrowth, and developmental delay, caused by a heterozygous mutation in the SETD2 gene on chromosome 3p21, which exhibits autosomal dominant inheritance.Case Report: A ten-year-old girl presented with menarche. She was born to healthy non-consanguineous parents at 37 weeks...

It has been recognized for over 20 years that there is an association between patterns of early growth and long-term risk of traditionally adult onset diseases such as type 2 diabetes. This has been observed both in human epidemiological studies and in animal models. This led to the concept of the developmental origins of health and disease that suggests that the environment to which an individual is exposed during critical periods of development, such as the in utero...

Background: Management of people with T1DM on intensive insulin therapy (IIT) uses algorithms based on the meal carbohydrate (CHO) content (MCC) to calculate prandial insulin dose. Typically, these calculations do not consider the meal content of fat or protein.Objective: To determine if the postprandial blood glucose (BG) response to varying fat content is dose dependent when standard insulin bolus is given based on MCC.Methods: R...

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...

Background: Diabetes insipidus (DI) is characterised clinically by the inappropriate production of large volumes of dilute urine even in the presence of clinical dehydration or deprivation of water. DI occurs either due to a deficiency or insufficiency of arginine vasopressin (AVP) hormone production. Hereditary DI accounts for <10% of the DI cases. As hyponatraemic seizures secondary to inappropriate use of desmopressin can occur, caution is required before a diagnosis of...
