A Belgian single centre outcome study of radioiodine treatment in adolescents with Graves' disease.

Up to 80% of children/adolescents with Graves' disease (GD) may require second-line treatment with either surgery or radioactive iodine (RAI) therapy after treatment with antithyroid drugs. These interventions aim to induce permanent hypothyroidism, but are not always successful. We aimed to evaluate the initial success rate (within the first year) of RAI treatment and its determining factors as second-line treatment in teenagers with GD.

MCM9 compound heterozygosity in an adolescent with premature ovarian insufficiency.

Summary: Delayed puberty in girls is often related to late maturation but is occasionally the first sign of premature ovarian insufficiency (POI). POI is a condition that affects ovarian function and fertility, and its etiology is unknown in most cases. Genetic factors have recently been identified in 20-25% of women with POI, involving genes that regulate various aspects of ovarian development and maintenance.

Optimizing Childhood Obesity Management: The Role of Edmonton Obesity Staging System in Personalized Care Pathways.

Childhood obesity, affecting 29% of 7-9-year-olds across 33 European countries, is a significant public health challenge. Its persistence into adulthood poses grave health risks influenced by genetic, environmental, and socio-economic factors. Belgium introduced a new care pathway in December 2023, based on the Edmonton Obesity Staging System for Pediatrics (EOSS-P), addressing four health domains and staging obesity severity.

Parsing Genetic and Autoimmune Etiology in Premature Ovarian Insufficiency.

Premature ovarian insufficiency (POI) is a rare cause of primary amenorrhea in adolescents. For young women with uncertain etiology of POI, genetic and autoimmune testing may be recommended to assist in treatment and management decisions. This report presents a case of POI in a 16-year-old adolescent with both poly-autoimmune disease and a heterozygous missense variant in the bone morphogenic factor 15 () gene, both potentially involved in the pathogenesis of POI.

Everything in excess is opposed to nature, even vitamin D: a case report.

Summary: Vitamin D intoxication in children is rare but its incidence is increasing as vitamin D is supplemented more often and in higher doses. Children with cystic fibrosis (CF) are at risk for vitamin D intoxication due to incorrect compounded preparations of liposoluble vitamins. Here, we report a severe vitamin D intoxication in a 4-year-old girl with CF, due to an error in the compounded vitamin A, D, E, and K preparation, presenting clinically with weight loss, constipation, polydipsia, polyuria, and nycturia.
