Background: >There is a wide variation in the reported rate of acute adrenal insufficiency (AI) related adverse events (sick day episodes and adrenal crises) between centres.Objective: Evaluate the level of consensus on the criteria that should be considered ‘essential’ for defining and managing adverse events associated with acute AI in children.Methods: Three groups of ...

Background: The circulating steroid metabolome in boys undergoes significant changes during infancy reflecting functional and structural rearrangements of the adrenal glands as well as the transient activity of the hypothalamic–pituitary–gonadal axis, also called minipuberty. Studies investigating the serum steroid metabolome dynamics during infancy in a longitudinal manner are however sparse.Objective: We ai...

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...

Objectives: Menarche is defined as the first menstrual bleeding in females, and the age of onset varies and depends on a complex interaction between genetic and environmental factors. The LIN28B gene single nucleotide polymorphisms (SNPs) rs314276, rs7759938 and rs314280 appear to be associated with cases of premature and early menarche. International databases report that the presence of a G allele of rs314280SNP shifts menarche 1.2 months earlier, a C allele...

Background: Craniopharyngioma is a non-malignant embryonic tumour in the pituitary-hypothalamic area, associated with hypothalamic obesity. Dysfunctional parasympathetic nervous system activity has been proposed as one mechanism underlying alterations in energy metabolism. Arterial spin labelling (ASL) is a non-invasive MRI technique that quantifies brain tissue perfusion as a proxy for functional activity. Here, we measure cerebral perfusion in patients with ...

Background: The male Hypothalamic-Pituitary-Gonadal (HPG) axis is transiently active during the first months of life with surging serum concentrations of reproductive hormones. This period, termed minipuberty, promotes masculinization, including testicular, and penile growth, as well as further testicular descent in males. It appears to be essential for priming specific cell types, i.e. Sertoli-, Leydig-, and germ cells, including subsequent growth and maturat...

Background: In 2020, the average glycaemic index of Type 1 diabetes (T1D) in Southeast Asia (SEA) countries were reported to be at around 83mmol/mol. In many low-middle-income countries (LMICs) in SEA, insufficient infrastructure, lack of universal health coverage and professional knowledge are factors that affect T1D outcomes that adversely affect mortality and morbidity. Action4diabetes (A4D) currently provides comprehensive partnership programmes with defin...

Background: The presentation of early-onset Primary Ovarian Insufficiency (EO-POI), most often with primary amenorrhea, is at one end of a spectrum spanning 40 years. The aetiology of POI is frequently unclear but next generation sequencing of varied age groups has identified several associated genetic variants. Whether girls with EO-POI are more likely to have a genetic aetiology than those with later presentations remains unknown.<stro...

Introduction: Growth hormone (GH) treatment is essential for growth in children with GH deficiency. Also short children born small for gestational age (SGA), and children with syndromes like Turner Syndrome (TS), Noonan Syndrome (NS) and Silver Russel Syndrome (SRS) can benefit from GH treatment. For children with needle anxiety GH delivered by a jet device can be a solution for the daily subcutaneous treatment for many years. In 2021, a global recall of the o...

Background: The initiation of puberty is dependent upon an augmentation of gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus. Development of the GnRH neuroendocrine network in embryonic life depends on coordinated migration of neurons from the vomeronasal organ in the nose to the forebrain. We have previously demonstrated that dysregulation in GnRH neuronal migration leads to delayed pubertal onset. Late puberty affects up to 2% of the ...
