Background: Testicular atrophy is a rare complication following inguinal hernia repair particularly in children<2 years and those with an undescended testis at highest risk> with an undescended testis. Inhibin B is secreted from the testis as a product of Sertoli cells, and has been suggested as a good marker for spermatogenesis. Its value is expected to be very low in children with bilateral testicular atrophyCase Report...

Background: Glibenclamide has proven to be efficient for patients with neonatal diabetes owing to potassium channel mutations. We developed a suspension of glibenclamide (EMA CHMP Authorization February 2018) fitting recommendations of drug administration to allow a precise dosage. We reported it to be practical, efficient and well tolerated after 3 months of use.Objective: To determine long term efficiency and tolerance of a new suspension of glibenclam...

Objective: Fear of hypoglycemia interferes frequently with metabolic control of type 1 diabetes especially in patients under 5 years of age who are at high risk of hypoglycemia and low metabolic control. Medtronic Minimed 640 G insulin pump with Smart Guard technology (suspension of insulin perfusion in predictive hypoglycemia situations) appears to be an adequate system for these patients by reducing the risk of hypoglycemia.Research design and methods:...

Background: The majority of children with short stature are classified as idiopathic short stature. Whole exome sequencing can help identify genetic causes of short stature.Methods: We recruited 10 children with short stature of unknown etiology. We conducted whole exome sequencing of the patients and their family members. We used an analysis pipeline to identify rare nonsynonymous genetic variants that might cause the short stature. All rare allelic var...

Background: severe primary insulin-like growth factor-1 deficiency (SPIGFD) is a rare growth disorder. Recombinant human insulin-like growth factor (IGF-1) (rhIGF-1; Increlex® [mecasermin]) replacement therapy is EU and US-approved for treating growth failure due to SPIGFD. The long-term therapeutic objective of rhIGF-1 treatment in SPIGFD is to improve adult height (AH). Objective: to describe the characteristics, safety and effectiveness data ...

Background: Congenital hypothyroidism (CH) is the most common neonatal endocrine disorder, with an incidence of 1:3000 neonates, and one of the most frequent preventable causes of mental retardation worldwide. Most (65%) cases of primary permanent CH are due to thyroid dysgenesis (TD). However, a genetic cause is identified in less than 5% of CH due to DT.Methods: We performed WES (Whole Exome Sequencing) for siblings with childhood-onset TD and we analy...

Aim of the Study: Cryptorchidism occurs more frequently in CF-children, and malformed epididymis was found more in cryptorchid boys with abrogated mini-puberty. Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) is transporter protein that acts as a chloride channel. Specifically, CFTR is associated with spermatogenesis and fertility.Patients and Methods: Testicular biopsies for histological and RNA analysis from...

Introduction: Propionic Acidaemia (PA), an organic acidaemia, is characterized by episodes of decompensation with severe metabolic acidosis and hyperammonaemia. PA is associated with low bone mineral density and osteoporosis. Hypocalcaemia is known to occur in 35-65% of decompensations, however the underlying pathophysiology remains unclear. PTH resistance has previously only been described in one case of hypocalcaemia in PA and we report the first use of ...

Background: Pseudohypoparathyroidism type 1b (PHP1b) is caused by epigenetic errors on the maternal GNAS allele at differentially methylated regions (DMRs) associated with exons A/B, XL, and NESP that lead to reduced production of Gαs transcripts most notably in the renal proximal tubule and thyroid follicular cells. Most PHP1b cases appear sporadically, few of which can be explained by paternal uniparental disomy involving chromosome 20q, leading to global methy...

Background: Graves’ disease therapy in young children may be challenging due to lack of therapy options. The safety of Radioiodine Ablation (RIA) has not been proven in children under age of 10 years. Propylthioracil (PTU) therapy has been linked to hepatic failure and became contraindicated in pediatrics.The case: A 6-year-old female was diagnosed with Graves ‘disease and treated with Methimazole (MTZ) and Propranolol. A few days after startin...
