Primary Hyperparathyroidism due to Parathyroid Adenoma in Children and Adolescents.

Objective: In contrast to adults, primary hyperparathyroidism (PHPT) in children and adolescents is a rare endocrine disorder.

Methods: A retrospective review of PHPT cases between 2005 and 2022 from a single tertiary university medical center, including clinical signs and symptoms, laboratory findings, radiological evaluation, treatment, and postoperative complications.

Results: Ten children (mean age at diagnosis 16.

High-intensity interval exercise test stimulates growth hormone secretion in children.

Background: exercise stimulates growth hormone (GH) secretion and may serve as a promising physiological test for the diagnosis of GH deficiency. However, exercise standardization for a feasible GH test is still lacking. The aim of the present study was to examine the GH secretion to high intensity interval exercise.

The Effect of Growth Hormone Treatment on Physical Performance Indices in Children With Idiopathic Short Stature.

Purpose: To examine the effect of growth hormone (GH) treatment on physical performance in children with idiopathic short stature and normal GH secretion.

Materials And Methods: A total of 24 children participated in the study (13 GH-treated, 11 non-treated, aged 8-13 y, 11 males and 13 females, Tanner stage 1-2). Participants performed a battery of motor skill performance tests (Eurofit), as well as the Wingate anaerobic test.

Reduced Growth Hormone Response to Anaerobic Exercise Among Children With Overweight and Obesity.

Hejla, D, Dror, N, Pantanowitz, M, Nemet, D, and Eliakim, A. Reduced growth hormone response to anaerobic exercise among children with overweight and obesity. J Strength Cond Res 36(8): 2194-2197, 2022-The aim of the present study was to examine the effect of an anaerobic exercise test on growth hormone (GH) secretion in children with overweight and obesity compared with children with normal weight.

Body composition and neuromotor development in the year after NICU discharge in premature infants.

Background: Hypothesis: neuromotor development correlates to body composition over the first year of life in prematurely born infants and can be influenced by enhancing motor activity.

Methods: Forty-six female and 53 male infants [27 ± 1.8 (sd) weeks] randomized to comparison or exercise group (caregiver provided 15-20 min daily of developmentally appropriate motor activities) completed the year-long study.

The "combined team" transition clinic model in endocrinology results in high adherence rates and patient satisfaction.

Background A structured transition process for young adults with chronic medical conditions from pediatric to adult clinics is strongly promoted. However, the most appropriate transition model has not yet been determined. This study evaluated the effect of a "combined team" Endocrinology Transition Clinic model, including a joint meeting with the patient and pediatric and adult endocrinologists, regarding medical treatment, adherence to follow-up and patient satisfaction with the process.

Expert's Choice: 2018's Most Exciting Research in the Field of Pediatric Exercise Science.

This commentary highlights 23 noteworthy publications from 2018, selected by leading scientists in pediatric exercise science. These publications have been deemed as significant or exciting in the field as they (a) reveal a new mechanism, (b) highlight a new measurement tool, (c) discuss a new concept or interpretation/application of an existing concept, or (d) describe a new therapeutic approach or clinical tool in youth. In some cases, findings in adults are highlighted, as they may have important implications in youth.

The Wingate anaerobic test cannot be used for the evaluation of growth hormone secretion in children with short stature.

Purpose: To assess the growth hormone (GH) response to the Wingate anaerobic test (WAnT) among children with short stature and suspected GH deficiency. We hypothesized that the GH response to the WAnT would be similar to the GH response to a commonly used pharmacologic provocation test.

Methods: Ten children (6 males and 4 females, age range 9.

Polymorphism of the IGF-I System and Sports Performance.

The potential use genetic polymorphism, and in particularly polymorphism of hormone genes, as tool to predict athletic performance is currently very challenging. Recent studies suggest that single nucleotide polymorphisms in IGF-I and myostatin may be beneficial for endurance and short distance running, and may even be associated with elite performance. Polymorphism in IGF-I receptor may differentiate between the two edges of the endurance-power athletic performance running spectrum suggesting beneficial effects for endurance and prevent from success in power events.

Growth without growth hormone: can growth and differentiation factor 5 be the mediator?

Growth without growth hormone (GH) is often observed in the setup of obesity; however, the missing link between adipocytes and linear growth was until now not identified. 3T3L1 cells were induced to differentiate into adipocytes and their conditioned medium (CM) (adipocytes CM, CMA) was added to metatarsals bone culture and compared to CM derived from undifferentiated cells. CMA significantly increased metatarsals bone elongation.

Alpha-1 antitrypsin therapy is safe and well tolerated in children and adolescents with recent onset type 1 diabetes mellitus.

Background And Objectives: Alpha-1 antitrypsin (AAT) has been shown to reduce pro-inflammatory markers and protect pancreatic islets from autoimmune responses in recent studies. Our aim was to evaluate its safety and tolerability in three different doses, in a pediatric population with recent onset type 1 diabetes mellitus (T1DM).

Methods: A 37-wk prospective, open-label, phase I/II interventional trial, comprised of 24 recently diagnosed subjects (12 males; age 12.

Rhabdomyolysis After Out-of-Water Exercise in an Elite Adolescent Water Polo Player Carrying the IL-6 174C Allele Single-Nucleotide Polymorphism.

We present an adolescent elite water polo player who despite a genetic predisposition to develop exercise-induced severe muscle damage due to carrying the IL-6 174C allele single-nucleotide polymorphism, developed acute rhabdomyolysis only after a vigorous out-of-water training, suggesting that water polo training may be more suitable for genetically predisposed athletes.

IGF-I and IGF-I receptor polymorphisms among elite swimmers.

In recent years several genetic polymorphisms related to the GH-IGF-I axis were suggested to promote athletic excellence in endurance and power sports. We studied the presence of the C-1245T SNP (rs35767), a nucleotide substitution in the promoter region of the IGF-I gene, and the presence of the 275124A > C SNP (rs1464430), a common nucleotide substitution in the intron region of the IGF-I receptor (IGF-IR) gene in elite long and short-distance swimmers compared with nonphysically active controls. The rare T/T IGF-I polymorphism was found only in 5.
