OBJECTIVES: The most suitable biochemical markers for therapy adjustment in patients with congenital adrenal hyperplasia are controversial. 11-Oxygenated androgens are a promising new approach. The objective of this study was to investigate the diurnal rhythm of 11-ketotestosterone in children and adolescents in saliva and to correlate it with salivary 17-hydroxyprogesterone. METHODS: Fifty-one samples of steroid day-profiles from 17 patients were additionally analysed for 11-ketotestosterone, retrospectively...

Prompt diagnosis and early treatment are key goals to optimize the outcomes of children with growth hormone deficiency (GHD) and attain the genetically expected adult height. Nonetheless, several barriers can hinder prompt diagnosis and treatment of GHD, including payer-related issues. In Saudi Arabia, moderate-to-severe short stature was reported in 13.1 and 11.7 % of healthy boys and girls, respectively. Several access and payer barriers can face pediatric endocrinologists during the diagnosis and treatment of GHD in Saudi Arabia...

OBJECTIVES: Inactivating GNAS mutations result in varied phenotypes depending on parental origin. Maternally inherited mutations typically lead to hormone resistance and Albright's hereditary osteodystrophy (AHO), characterised by short stature, round facies, brachydactyly and subcutaneous ossifications. Paternal inheritance presents with features of AHO or ectopic ossification without hormone resistance. This report describes the case of a child with osteoma cutis and medulloblastoma...

OBJECTIVES: Secondary hyperparathyroidism (sHPT) is an important contributor to bone disease and cardiovascular calcifications in children with chronic kidney disease (CKD). When conservative measures are ineffective, parathyroidectomy is indicated. The aim of our study was to evaluate the efficacy and safety of subtotal parathyroidectomy (sPTX) in pediatric and adolescent patients, and to provide a rationale for considering this aggressive treatment in CKD patients with uncontrolled sHPT...

OBJECTIVES: This study aimed to identify discrepancies in the retinal nerve fiber layer (RNFL) between type 1 diabetes mellitus (T1DM) children without retinopathy and healthy subjects in northern China. METHODS: This was a cross-sectional hospital-based study carried out from Jan 2019 until Jul 2021 at the department of pediatrics in Tianjin medical university general hospital. Children with T1DM but no retinal disease were screened. RNFL thickness was obtained via spectral domain optical coherence tomography...

OBJECTIVES: Wolfram syndrome is characterised by insulin-dependent diabetes (IDDM), diabetes insipidus (DI), optic atrophy, sensorineural deafness and neurocognitive disorders. The DIDMOAD acronym has been recently modified to DIDMOAUD suggesting the rising awareness of the prevalence of urinary tract dysfunction (UD). End stage renal disease is the commonest cause of mortality in Wolfram syndrome. We present a case series with main objective of long term follow up in four children having Wolfram syndrome with evaluation of their urodynamic profile...

OBJECTIVES: Lingual thyroid is a rare condition that affects approximately 1 in 100,000 individuals. Although it is usually detected in the pediatric population through newborn screening tests or evaluation of congenital hypothyroidism, there are cases in which it remains undetected until adulthood or until symptoms arise because of glandular enlargement. The possible symptoms of lingual thyroid include foreign body sensation in the throat, dysphagia, dyspnea, and hemorrhage. Several cases of lingual thyroid are asymptomatic and accompanied by subclinical hypothyroidism...

OBJECTIVES: Arginine-stimulated serum copeptin has been proposed as a new method to diagnose arginine vasopressin (AVP) deficiency in children and adolescents. Herein we investigated the secretagogic potential of clonidine or L-Dopa on the copeptin serum levels in children. METHODS: Eight stimulation tests (4 with clonidine and 4 with L-Dopa) were performed in eight children (5 boys and 3 girls) with a median age of 6.5 years-old, evaluated for short stature due to possible growth hormone deficiency...

OBJECTIVES: A connection between thyroid hormones (THs) and diverse metabolic pathways has been reported. We evaluated thyroid function and tissue sensitivity to THs in children and adolescents with T1D in comparison to euthyroid controls. Additionally, we investigate whether a relationship exists between sensitivity indices and metabolic parameters. METHODS: A retrospective analysis was conducted on 80 pediatric patients diagnosed with T1D. Clinical parameters, TSH, FT3, FT4, and the presence of MS were documented...

BACKGROUND: Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder characterized by impaired activity of the enzyme required for cortisol and aldosterone production, resulting in increased adrenal androgen synthesis. Factors affecting fertility in CAH patients include ambiguous genitalia and their complications, excessive androgen secretion, adrenal progesterone hypersecretion, and various psychosocial factors. Serum anti-Müllerian hormone (AMH) level is used to assess ovarian reserve in women...

OBJECTIVES: The genetic causes of pituitary stalk interruption syndrome (PSIS) remain elusive in 95 % of cases. The roundabout receptor-1 gene ( ROBO1 ) plays critical roles in axonal guidance and cell migration. Recently, mutations in the ROBO1 gene have been reported patients with PSIS. CASE PRESENTATION: We report a 2.9-year-old boy with PSIS who presented with combined pituitary hormone deficiency, central diabetes insipidus, and the classical triad of MRI findings...

OBJECTIVES: Transcobalamin II (TC) promotes the cellular uptake of cobalamin (Cbl) through receptor-mediated endocytosis of the TC-cbl complex in peripheral tissues. TC deficiency is a rare disorder that causes intracellular Cbl depletion. It presents in early infancy with a failure to thrive, diarrhea, anemia, agammaglobulinemia, and pancytopenia. Data from five TC-deficient patients including clinical, biochemical, and molecular findings, as well as long-term outcomes, were collected...

OBJECTIVES: This prospective multicenter study aimed (1) to examine changes in parent-reported health-related quality of life (HRQOL) of children with short stature and the effects of the children's condition on parents themselves within the first year of human growth hormone (hGH) treatment and (2) to predict effects on parents based on main and interaction effects of children's HRQOL and increase in height. METHODS: A total of 110 parents of children aged 4-18 years, diagnosed with idiopathic growth hormone deficiency, small for gestational age, or idiopathic short stature, were recruited from 11 participating German pediatric endocrinologists and asked to fill out the short stature-specific Quality of Life in Short Stature Youth (QoLISSY) Questionnaire before hGH treatment was initiated and one year later...

OBJECTIVE: Plant-based milk alternatives are increasingly utilized in children with cow milk allergy, lactose intolerance, and personal preference. However, notable differences exist in mineral content between cow milk and plant-based alternatives. Almond milk, in particular, varies in mineral and caloric content across different brands. This case report highlights a toddler who developed hypercalcemia and hypophosphatemia attributed to almond milk consumption. CASE PRESENTATION: A fourteen-month-old girl with a history of biliary atresia underwent liver transplant at seven months of age...
