Pediatric diabetes management extends beyond glycemic control. A gap between guidelines and actual care exists. Standardized performance measures represent a key strategy to improve quality of care. In Italy, a non-profit initiative of continuous monitoring and quality improvement of diabetes care is in place since 2018, promoted by the ISPEDCARD association and involving the Society for Pediatric Endocrinology and diabetology (ISPED). Aim of the present work is to report the ...

Background: Inherited epidermolysis bullosa (EB) comprises a cluster of genetic disorders characterized by blistering of skin and mucosae following minimal mechanical traumas. Severely affected individuals have high risk of extracutaneous complications, including chronic undernourishment and low bone mass.Objective and hypotheses: The aims of this study were to assess the areal bone mineral density (aBMD) and vitamin D status of children and adolescents ...

The Ovotesticular Disorder of Sexual Development (OT DSD) is a rare condition characterized by histologic demonstration of both ovarian and testicular tissue in the same individual. Descriptions in literature usually have small samples and do not include patient evolution data. The aim of this study is to describe clinical, biochemical and histological findings, as well as long-term outcomes (including onset and progression of puberty) in patients with OT DSD, accompanied betw...

Background: Studies on the follow-up of 46,XY partial gonadal dysgenesis (PGD) patients till adulthood are scarce and it is important to provide information to parents on the prognosis of gonadal dysgenesis.Objective and hypotheses: To analyze the long term outcomes of 46XY PGD patients in both social sexes regarding testosterone production, social sex adaption and genotype.Method: Retrospective longitudinal study conducted at Hosp...

Background: Prader–Willi syndrome (PWS) patients have been followed in our country in different ways but without a reference center. In January 2015, we started a PWS reference center in Sao Paulo University to promote a better care for patients and families and to support them with a multidisciplinary team, including pediatric endocrinologist, dietician, nurses, neurologist specialized in sleep disorders and otorhinolaringologist.Method: Forty-two ...

Introduction: The circadian rhythmicity of the hypothalamic–pituitary–adrenal (HPA) axis depends on the synchronization of the clock molecular systems in the suprachiasmatic nucleus and in the adrenals. When and how this process occurs in the adrenal is unknown.Objective: To assess the ontogeny of daily variation of the expression of the adrenal clock genes (Clock, Arntl, Per1, Per2, Per3, Cry1, Cry2, Rora, and Nr1d1), steroid...

Background: The aetiology of congenital hypopituitarism (CH) is unknown in the majority of patients. In our cohort of 200 cases, it was possible to establish the genetic cause in only 13 patients (6.5%). Copy number variants (CNVs) have been implicated as the cause of genetic syndromes with previously unknown aetiology.Objective: To study the presence of CNVs and its relevance in patients with CH of unknown cause associated with complex phenotypes.<p...

Background: Idiopathic central precocious puberty (CPP) is mostly described as an isolated entity. A few studies have shown its association with clinical syndromes and rare cases of chromosomal abnormalities.Objective: To clinically characterize patients with CPP, pointing out prevalent associated conditions and phenotypes.Patients and Methods: One hundred and forty-five patients with idiopathic CPP were retrospectively evaluated. ...

Background: Isolated Growth Hormone Deficiency (IGHD) is usually associated with a delayed bone age. A genetic cause for IGHD is more frequently found in patients with familial cases and/or consanguineous parents.Objective and hypotheses: To diagnose the genetic cause of IGHD and clarify the unusual clinical presentation of advanced bone age in one patient born to consanguineous parents.Method: Sanger sequencing of GH1, <e...

Introduction: DSD patients present varied degrees of atypical genitalia. The social sex assignment and the surgery decisions must be proceeded by a multidisciplinary team approach with the family. Surgeries should be only performed by experienced surgeons. The current trend is the early correction, but some patients and non-governmental entities argue that the surgeries should be delayed until the patient’s consent.Objective...
