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...

Background: α-klotho is a transmembrane protein which can be cleaved and act as a circulating hormone. Since low α-klotho levels were found in organic GH deficiency (GHD) and high levels in acromegaly, an interaction between α-klotho, GH and linear growth has been suggested.Objective and hypotheses: We investigated the role of α-klotho protein as a reliable marker of GH secretion in short children and the factors influencing its secre...

Introduction: Glucose sensor usage is increasing in the paediatric type 1 diabetes population. The sensor downloads can provide valuable information about glycaemic levels over a 90-day period and generate an estimated HbA1c based on the average glucose level.Aim: We aimed to test whether the sensor-estimated HbA1c over 90 days was an accurate prediction of the measured HbA1c and whether its accuracy correlated with perc...

Background: Cystic fibrosis-related diabetes (CFRD) is the most common co-morbidity in association with cystic fibrosis. Cystic fibrosis related diabetes is predominantly an insulin deficiency state it shares features of both type 1 and type 2 diabetes, yet there are important differences, which necessitate a unique approach to diagnosis and management. Development of cystic fibrosis related diabetes is associated with a worse lung function, poorer nutritional status, and more...

Background: Premature ovarian failure (POF) is uncommon in pediatrics and when occurs during the adolescence is typically iatrogenic or due to chromosomal anomaly. Also many genes have been identified that contribute to the development of POF, and most of these mutations are extremely rare.Objective: We describe a case of 15 years old female presented short stature and secondary amenorrhea, after a normal puberty but without peak height velocity. She was...

Background: Cushings syndrome is a rare entity in children and generally it presents a female to male predominance. The most common cause in childhood is iatrogenic Cushings syndrome related to chronic administration of glucocorticoids or ACTH. Endogenous Cushings syndrome is divided into ACTH dependent (ACTH overproduction due to pituitary adenoma or ectopic production) and in ACTH independent causes (surrenal adenoma, carcinoma, or bilateral hyperplasia).<p class="abstex...

Background: Macroprolactinomas are rare during childhood. Hypopituitarism is a common feature and recovery of pituitary function was reported following cabergoline therapy.Objective: We present a case of 13 year-old boy with macroprolactinoma who responded to cabergoline therapy with a complete regression of the tumor with a partial empty sella.Results: He complained of a decreased of right vision since 1 year. Evaluation of anteri...

Background: Melanocortin-2 receptor (MC2R) is a member of the G protein-coupled receptor family. MC2R is selectively activated by adrenocorticotropic hormone (ACTH); the binding of MC2R and ACTH activates the heterotrimeric G protein complex, and in turn stimulates steroidogenesis. Pathogenic variants in the MC2R gene result in glucocorticoid deficiency-1 (GCCD1), an autosomal recessive disorder in which unresponsiveness to ACTH leads to deficient secretion of cortisol and adr...
