Introduction: Although the safety and effectiveness of recombinant human growth hormone therapy (rhGH) has been reported for several years, the level of consensus on the outcomes that should be reported is unclear. The aim of this systematic review is to study the frequency of reporting of these outcomes in children with GH deficiency (GHD).Methods: A systematic review was performed in Medline, Embase, Cochrane Central R...

Background: The adrenal cortex undergoes constant cellular renewal and any effect from recombinant adeno-associated vectors (rAAV) targeting differentiated cells will be transient as extra-chromosomal DNA will be lost by dividing cells. A novel option is to use rAAV to express ectopic adrenocortical enzymes in a stable organ outside the adrenal gland. Our aim was to correct the biochemical phenotype in a mouse model for congenital adrenal hyperplasia (CAH) wit...

Introduction: The clinical hallmark of male puberty is testicular enlargement ≥4 ml. While this initial sign largely depends on central reactivation of the hypothalamic-pituitary-gonadal (HPG) axis along with peripheral follicle-stimulating hormone (FSH) action, the attainment of voice-break, activation of sweat- and sebaceous- glands, acne as well as axillary hair development require testosterone action.Objective: To investigate the tempo...

Background: Hyperphosphatemic conditions such as chronic kidney disease are associated with muscle wasting and impaired life quality. While muscle regeneration relies on myogenic progenitor recruitment, the effects of high phosphate loads on this process has not been investigated in detail. This study aims to clarify the direct effectsof hyperphosphatemic conditions on skeletal myoblast differentiation in an murine cell model system.Material and methods:...

Objective: To present a patient with hypercalcemia caused by a parathyroid adenoma and a deletion of the VDR gene.Case clinic: The case is that of a 13-year-old male who presented with hypercalcemia, muscle weakness, nephrocalcinosis, two pathological fractures and a family history of nephrocalcinosis. Physical examination was unremarkable, except the presence of a fracture of the left femur. Laboratory findings: Total s...

Background: Familial Hypocalciuric Hypercalcemia (FHH) type 1 is a benign condition of hypercalcemia with autosomal dominant inheritance caused by pathogenic variants in the calcium-sensing receptor gene (CASR). CaSR plays a crucial role in the regulation of calcium balance. Inactivating mutations in CASR result in altered calcium-sensing and inappropriate parathyroid hormone (PTH) release concerning the calcium concentration. Dysplasia Epiph...

Introduction: Salivary androgens represent a non-invasive marker of puberty that may have utility in population studies as well as in the clinical arena.Objectives: To establish normal reference values of salivary androgens using LC-MS/MS and demonstrate the correlations between salivary androgens and pubertal development in boys.Methods: School-based adolescent cohort study with t...

Background: Severe insulin resistant (IR) type A is a rare inherited disorder characterized by glucose metabolism disturbances without obesity, acanthosis nigricans and hyperandrogenia due to INSR defects.Case report: A 10-year-old girl was admitted because of skin papillomatosis and hyperpigmentations since her 7 years. She had early puberty with pubarche at 8 years and telarche at 9 years. Examination revealed normal height and weight (SDS BMI...

Background: NSIAD is a rare genetic cause of hyponatremia, due to activating mutations in AVPR2 gene, encoding the Arginine Vasopressin Receptor Type 2, and located on Xq28. Of the fewer than 30 reported cases, most have been managed with fluid restriction and urea.Objective and hypotheses: Illustration of the presentation of a family with this genetic abnormality and approach to management.Method: The clinical, biochemical and gen...

Background and Objectives: Enlargement and cystic changes in ovaries of patients with longstanding overt hypothyroidism has been observed in numerous case reports. But there is limited data about the effect of subclinical hypothyroidism (SH) on ovarian volume and ovarian cyst formation. We evaluated the relationship between serum thyroid stimulating hormone (TSH) level and ovarian volume and sonographic appearance in prepubertal girls with SH.<p class="abs...
