Background/Aims: Magnetic resonance imaging (MRI) is used to investigate the etiology of growth hormone deficiency (GHD). There is a close relationship between structural changes in the pituitary gland and clinical status.We aimed to investigate the relationship between MRI findings and clinical symptoms and treatment response in children with GHD.Methods: The study was conducted in nine Department...

Background: SHOX and enhancer regions on PAR1 disorders have variable phenotypic consequences such as idiopathic short stature (ISS) and Leri-Weill Dyschondrosteosis (LWD).Objective and hypotheses: The aim of this observational multicentric study was to describe phenotypes and genotypes of a large population with mutation on SHOX and adjacent regions and to identify a possible phenotype–genotype correlation.M...

Background: The diagnosis of 46,XY disorder of sex development (DSD) due to 5-alpha reductase 2 (5α-RD2) deficiency has been based on testosterone:dihydrotestosterone (T:DHT) ratio, urinary steroid profiling and mutational analysis of SRD5A2 gene. The biochemical hallmarks of 5α-RD2 deficiency include increased T:DHT ratio. However, several difficulties are observed in the DHT measurement leading to misdiagnosis. The mutational analysis of the SRD5A2 has been propose...

Background: Gonadectomy is generally postponed until early adulthood in complete androgen insensitivity syndrome (CAIS) and close surveillance of gonads in situ proposed in males with partial AIS (PAIS). Delaying gonadectomy further is controversial given the lack of data regarding germ cell cancer (GCC) development in adulthood and the absence of biomarkers for noninvasive GCC screening.Aims and objectives: To study the prevalence of invasive G...

Context: Differences in sex development (DSD) represent a broad spectrum of conditions that can present at different ages to various healthcare professionals with different backgrounds.Design: This is a retrospective, observational cohort that includes all DSD subjects referred to a multi-professional DSD team over a period of 41 years (from 1980 to 2021).Participants: A total of 6...

Introduction: Generally, patients with X-linked hypophosphatemic rickets (XLH) experience normal puberty. However, they can be affected by metabolic and environmental factors that may predispose them to central precocious puberty (CPP) and impair their predicted final height, similar to the general population.Case Report: A female patient was diagnosed with XLH at three and received regular treatment with calcitriol and ...

Background: The individual growth response on a certain GH dose is an indirect measurement of tissue responsiveness to GH. Several models of predicting the first year growth response on GH treatment are published and a clinical trial has been performed based on these algorithms. However, no clinical unit has evaluated the practical use of these prediction models on GH treatment.Objective and Hypotheses: To use prediction models in clinical practice to ch...

Background: The increasing number of transgender adolescents presenting in early puberty requires to investigate the effects of long-term puberty suppression and gender-affirming hormones (GAH) on body composition and metabolism. Clinical studies have ethical and practical limitations. A preclinical mouse model may be helpful to gain mechanistic insights.Methods: Prepubertal (4week-old) female mice were treated with the ...

Background: Transgender individuals increasingly present at gender services in childhood. Consequently, to suppress pubertal development, more adolescents are long-term exposed to gonadotropin-releasing hormone analogues (GnRHa), from onset of puberty until start of gender-affirming hormones (GAH), around 16 years. Prolonged GnRHa may compromise bone health more than shorter-term treatment. If earlier start of GAH, when psychologically indicated, may partially...

Introduction: Bone fragility or predisposition to fractures with low-impact energy is a rare but potentially limiting condition. Variations in PLS3 gene are a cause of monogenic osteoporosis due to the alteration of osteoclast and osteocyte function and bone mineralization. It is characterized by early-onset osteoporosis, peripheral fractures, vertebral compression fractures and thoracic kyphosis. Due to its X-linked inheritance, the phenotype is more severe i...
