During the COVID-19 pandemic, a significant increase in Central Precocious Puberty(CPP) has been observed worldwide. The reasons for this phenomenon are yet unclear. In order to evaluate if fear, stress and coping strategies used by children and parents when dealing with negative emotional situations and health issues might have acted as triggers for this phenomenon, we administered specific questionnaires to girls who had a diagnosis of CPP before and after the COVID-19 relat...

Background: Congenital hypopituitarism (CH) genetics is highly heterogeneous. The massive use of NGS identified at least 21 desease causing genes. Not fully understood inheritance mechanism, incomplete penetrance and variable expressivity explain the complexity of phenotype-genotype correlations. To further complicate the scenario, the co-occurence of more than one desease-causing genes variants can geopardize the phenotype. Herein, we report the heterogeneous...

Background: Polyuria and polydipsia syndrome (PPS) workup is not straightforward, especially in children. Basal investigations are often not reliable in distinguishing among diabetes insipidus (DI), central (CDI) or nephrogenic (NDI), and primary polydipsia (PP). Water deprivation test (WDT) is often essential, although uncomfortable and not always reliable enough to recognize partial DI. Plasma AVP investigation is not routinely used in the diagnostic pathway...

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: Adrenal insufficiency (AI) is a rare condition caused by an inadequate production of glucocorticoids. Preliminary data in adults suggest that AI could be associated with an increased susceptibility to infections; moreover, AI patients are at risk to develop a severe course of infectious diseases and to experience a life-threatening adrenal crisis. The aim of our study is to evaluate the severity and the outcome of COVID-19 in pediatric AI patients ...

Background: Children with familial forms of central diabetes insipidus (CDI) display polyuria and polydipsia within the first years of life.Objective and hypotheses: We hypothesize that children with an early-onset idiopathic CDI might be affected by de novo genetic mutations.Method: Eleven children aged between 1 month and 7 years with polyuria and polydipsia and negative family history were enrolled. In nine of them with...

Background: Congenital hypothyroidism (CH) is considered as the most common endocrine disorder in neonates. CH may be caused by defects in the thyroid gland (dysgenesis) or in one of the stages in the synthesis of thyroid hormones (dyshormonogenesis). Early diagnosis and treatment of neonates with CH is crucial for their neurological development and preventing its related mental retardation. CH screening program have made the opportunity to achieve the mentioned goals. CH scre...

Puberty is a crucial biological process normally occurring at a specific time during the lifespan, during which sexual and somatic maturation are completed, and reproductive capacity is reached. Pubertal timing is not only determined by genetics, but also by endogenous and environmental cues, including nutritional and metabolic signals. During the last decade, we have learned much regarding the essential roles of kisspeptins and the neuropeptide pathways that converge on these...

Objective: Through the diagnosis and treatment of Uighur girl with adrenocortical adenoma, who was complain of short stature, to prompt pediatric endocrinologists pay attention to hypercortisolism in the diagnosis and treatment of children with short stature.Methods: With the case report of hypercortisolism in a Uighur child, to introduce the diagnosis and treatment of adrenocortical adenoma, presenting the clinical char...
