Background: Thyroid cancers are rare in childhood. ATA guideline (Pediatric section) has been applied in daily practice since 2015. It is very significant to accurately predict the risk in the management of differentiated thyroid cancer(DTC). For this purpose, we shared our single center-20-year-experience about the follow-up features and management of childhood and adolescent thyroid cancer. We aimed to evaluate the dynamic risk stratification (DRS) and the o...

Background: Phosphoglucomutase 1 (PGM-1) deficiency is a congenital disorder of glycosylation caused by an impairment of glucose-1-phosphate and glucose-6-phosphate interconversion.The clinical phenotype of PGM1 deficiency is variable and includes several endocrine manifestations such as recurrent hypoglycemia and short stature, which may be associated with the decreased levels of growth hormone (GH), insulin like growth factor-1 (IGF1) ...

In children with XLH, excess FGF23 causes hypophosphatemia with consequent rickets, skeletal deformities, and impaired growth and mobility. We reported that burosumab improved phosphate homeostasis and rickets in children with XLH. Here, we present data on 11/52 subjects (all girls) who developed fused growth plates during the phase 2 study CL201 (NCT02163577).In CL201, 52 subjects (Baseline: 5-12 years-old, Tanner ≤ 2) were randomized 1:1 to recei...

Background: Congenital diabetes insipidus (DI) can be due to mutations in the arginine vasopressin (AVP) gene (familial neurohypophyseal DI), the AVP receptor type 2 (AVPR2) or aquaporin 2 (AQP2) genes (congenital nephrogenic DI, NDI). The clinical manifestation of congenital NDI, especially the response to AVP, can vary greatly depending on the functional effect of the AVPR2 mutation. Here we present two male siblings with NDI and partial response to ddAVP.<p class="abste...

Introduction: Achondroplasia is caused by a pathogenic mutation in the FGFR3 gene, leading to impaired endochondral bone growth and multiple medical complications. Vosoritide, a modified recombinant human C-type natriuretic peptide (rhCNP), was approved by the European Medicines Agency (EMA) in August 2021 for treating genetically confirmed achondroplasia in patients aged ≥2 years until closure of epiphyses. Acorn is the first treatment-based registry for a...

Context: Children with 21-hydroxylase deficiency (21OHD) require chronic glucocorticoid administration to substitute glucocorticoids and suppress adrenocorticotropic hormone-induced hyperandrogenemia. There is still no evidence about the best timing of the highest hydrocortisone (HC) dose. Administration of the highest dose in the morning aims to mimic the physiological rhythm of cortisol, while a high dose late in the evening may inhibit the early-morning inc...

Objective: Analyze CCH detection program results from 3 Autonomous Communities: TSH and total T4 (TT4) in dried blood spot (DBS) at initial screening (48 hours of life) and at retesting. Describe the characteristics of neonates with screening compatible with CCH. Consider whether TBG deficiency (TBGD) is an added difficulty in said study.Materials and Methods: Retrospective study (May 2016-May 2020) of all neonates ≥33 weeks and/or ≥1500 gr...

We present the case of a now 11 years old girl with the ultra-rare severe insulin resistance Rabson-Mendenhall syndrome due to the previously undescribed compound heterozygous mutations exon 16: c.2986A>G (Paternal) and intron 9: c.2029+1G>T (maternal) of the insulin receptor gene. The phenotypic findings were composed of dystrophy (birth weight 1970g, small for gestational age), hyperglycemia (up to 400mg/dl), severe acanthosis nigricans and mild cardiac septal hyperpla...

Background: A decrease in random LH concentration is observed after initiation of treatment for central precocious puberty (CPP), but the suitability of random LH concentrations for assessing efficacy is controversial. Although Neely et al. reported that random LH values frequently fail to demonstrate suppression to prepubertal levels,1 Lee et al. demonstrated that a cutoff of random LH <0.6 IU/l may be adequate for monitoring s...

Aim: To investigate the prevalence of hirsutism among adolescents using the modified Ferriman-Gallway (FG) Scale and to determine etiological factors in childen with hirsutism.Materials and methods: The study was in 2380 female adolescents aged 12–18 years. The modified FG score was used in the diagnosis and monitoring of hirsutism. Scores of 8 or above were regarded as hirsutism. Two hundred thirty-three volunteers determined as having hirsutism we...
