Background: Secondary pseudohypoaldosteronism (PHA) type 1 is an uncommon salt losing condition of infancy caused by transient resistance of the mineralocorticoid receptors (MR) of the renal tubule to aldosterone. This can be secondary to urinary tract infection (UTI), urinary tract malformation (UTM) or obstructive uropathy. Ninety percent of reported cases present before 3 months and nearly all are under 7 months of age.Objective and hypotheses: The co...

Background: Ireland has a high incidence of type 1 diabetes in childhood (16.8/100, 000 per year (1). A small percentage of children with diabetes have maturity onset diabetes of the young (MODY) (2). Establishing the correct diagnosis is critical to optimal therapy and future genetic counselling (3).Objective and hypothesis: To review the cohort of children attending our tertiary diabetes service and describe the clinical features of those where MODY wa...

Background: Neonatal diabetes mellitus (NDM) is a relatively rare form of monogenic diabetes and usually presents in the first 6–9 months of life. In this study, our objective was to report the clinical details, perform a detailed genetic analysis and acquire a clinical–phenotype correlation of our cohort.Materials and methods: NDM patients referred to SN Endocrine centre between period of Nov 2014 to April 2017 and patients under follow-up wit...

Introduction: Hypogonadotropic hypogonadism (HH) is a rare condition, where a definitive diagnosis is often hard to reach.Objectives: To describe the clinical, biochemical and genetic findings in cases with suspected HH in the West of Scotland who were referred for genetic analysis between 2016 and 2020.Methods: Information was collected on clinical assessment including family hist...

Objective: To describe clinical, laboratory and genetic characteristics of 42 short children from 34 consanguineous Turkish families.Design: Descriptive case series.Methods: After collecting clinical information, DNA samples were analysed in three European laboratories. In 18 children (12 families) suspected of a genetic defect in the growth hormone (GH)-insulin-like growth factor ...

Epiphyseal growth plates, tiny cartilage discs located to the end of long bones, are necessary for longitudinal growth of the skeleton. When and why these structures appeared as individual organs was not very clear until recently. Bringing together an evolutionary approach with comparative analysis, mathematical modelling and both physical and biological experiments allowed to reveal that spatial allocation of the growth plate reduces mechanical stresses within the structure, ...

Background/Objective: Micro-and macrovascular changes are the cause for diabetes complications. Retinal vessel analysis is a unique method to examine microvascular changes in brain derived vessels.Subjects/Methods: Sixty-seven pediatric and adolescent type 1 diabetes patients and 58 healthy control persons underwent nonmydriatic retinal photography of both eyes. Arterioles and venules positioned in the region 0.5 to 1 diameter of the optic disc measured ...

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED, OMIM240300) is a rare monogenic disease due to biallelic mutations in the Autoimmune Regulator (AIRE) gene. This encodes for a thymus-enriched transcription factor responsible for central immune tolerance. Classic diagnostic criteria are the presence of two of main symptoms of chronic mucocutaneous candidiasis (CMC), hypoparathyroidism (HP) and Addison’s disease (AD). Non-endocrine autoimmun...

Introduction: The prevalence of PCOS in adolescents and young women was established at 4.3%. Whether women with a history of ICPP are at increased risk for PCOS is still controversial. There is no clear evidence that ICPP girls treated with GnRH analogues (GnRHa) are more likely to develop PCOS than their age-matched peers.Objectives: To assess the prevalence of PCOS in adolescents with a history of ICPP and further comp...

Background: Congenital hypogonadotropic hypogonadism (CHH) is caused by impaired function of GnRH neurons, which clinically manifests by incomplete or absent puberty and infertility. The phenotype may be broader with other developmental anomalies such as anosmia, which is known as Kallmann syndrome. To date, there are more than 40 genes in which mutations underlie CHH. Cornelia de Lange Syndrome (CdLS) is characterized by facial dysmorphia, psychomotor delay, ...
