Background: Patients with hyperinsulinism (HI) and anterior hypopituitarism often present in the new-born period (NBP). However up to 30% patients with HI and an unknown number with hypo-pit will present in the first year of life. Despite advances in care the long-term neurological outcome for patients with HI is poor in 20-40% cases.Aim: To retrospectively evaluate the care given during the NBP in a series of patients diagnosed with late presenting pote...

Introduction: Focal disease of the pancreas causing hyperinsulinism (FHI) has 2 essential characteristics 1) the inheritance of a paternally derived mutation in ABCC8 or KCNJ11 in conjunction with loss of a region of the maternal chromosome 11p13.1 and 2) the ability to be cured by resection of the focal lesion while sparing the majority of the pancreas. At the time of surgery the surgeon resects the focal lesion until clear margins are avail...

Introduction: 6 Mercaptopurine (6MP) is a cornerstone of maintenance therapy in pediatric acute lymphoblastic leukemia (ALL). Fasting hypoglycemia is a rare side effect of 6MP therapy that has been observed in children being treated for ALL. We present two pediatric patients who developed symptomatic, fasting hypoglycemia during maintenance therapy.Case Description: A 7-year-old male with standard risk B ALL receiving ma...

Background: DICER1 is a member of the Ribonuclease III family that plays a crucial role in the biogenesis and the maturation of microRNAs. Pathogenic germline DICER1 variants cause a hereditary cancer predisposition syndrome with a variety of manifestations: in addition to first described pleuropulmonary blastoma (PPB) and ovarian sex cord-stromal tumours, individuals may also develop benign (multinodular goiter MNG, cystic nephroma\.) or malignant tumours as differen...

Background: Monitoring treatment of children with classic congenital adrenal hyperplasia (CAH) is difficult and biochemical targets are not well defined.Objective and hypotheses: To analyse the urinary steroid metabolome of children with classic 21-hydroxylase deficiency (21-OHD) during treatment with hydrocortisone and fludrocortisone.Method: We retrospectively analysed 553 daily urinary steroid hormone metabolite profiles determi...

Background: NSIAD is a rare genetic cause of hyponatremia, due to activating mutations in AVPR2 gene, encoding the Arginine Vasopressin Receptor Type 2, and located on Xq28. Of the fewer than 30 reported cases, most have been managed with fluid restriction and urea.Objective and hypotheses: Illustration of the presentation of a family with this genetic abnormality and approach to management.Method: The clinical, biochemical and gen...

Background: The incidence of perinatal stress hyperinsulinism (PSHI) requiring diazoxide treatment is estimated to be 1:12,000 (Hoe et al., 2006). Diazoxide is used to treat PSHI, but it has been shown to have adverse effects including pulmonary hypertension. Gray et al, reported that of 1.25 million infants admitted to NICUs for hypoglycemia over a period of 18 years, only 1066 received diazoxide suggesting 1:1172 babies had HI however 92% o...

X-linked hypophosphatemia (XLH, MIM 307800) is a rare hereditary disorder of bone metabolism characterized by growth impairment, leading to bone deformities and short stature and beside others to muscle function deficits. XLH is caused by defect of endopeptidase PHEX leading to high levels of FGF-23 and thereby renal phosphate wasting. While conventional treatment includes substitution of phosphate and 1-25 OH-Vitamin D, now a treatment with a FGF-23 antibody (burosumab) is av...

Background/Aim: Parents wanting to predict adult height (AH) often resort to the old practice of doubling a boy’s height at age 2 years or a girl’s height at 18 months. We coined this the ’Grandma prediction’ (GMP1). It provides predictions with mean absolute error (MAE) 5.9 and 5.2, standard deviations of residuals (sdRES) 4.1 and 3.6, and Pearson correlation r=0.68 and 0.67 for boys and girls, respectively. The recent sophist...

Background/Aim: The trade-off theory claims that a resource (calorie) stored in adipose tissue cannot be used for longitudinal growth, and a calorie used for growth will not be stored as fat.Methods: Out of 2339 children with longitudinal heights and weights (birth to adulthood) from the GrowUp1990 Gothenburg cohort, 1993 (996 girls) were analyzed. For everyone we calculated Energy Trade-Off Score: ETOS = at early adulth...
