Background: Several studies have suggested that vitamin D supplementation in early childhood is successful in decreasing the risk of type 1 diabetes (T1D) through a complex immunomodulatory role. However, Intervening in disease once clinical symptoms have appeared and autoreactive immune responses are active might be more challenging. Controlled trials with vitamin D supplementation in recent-onset T1D have shown mixed results.Objective and hypotheses: T...

Background: A compromised final height (FH) is a concern in patients diagnosed with congenital adrenal hyperplasia (CAH). The lack of achievement of the genetic target height (TH) can be attributed to treatment with high doses of corticosteroids and high levels of adrenal androgens. Despite the emergence of new therapeutic modalities such as the use of anti-androgens and growth hormone it has been shown that a favorable FH can be achieved with careful use of corticosteroids.</...

Background: Testicular tumours are an unusual cause of prepubertal gynecomastia. However, in boys with Peutz-Jeghers Syndrome (PJS), a rare autosomal dominant disorder caused by mutation in LKB1/STK11 gene, is mandatory to exclude this etiology, given the well-known association between PJS and Large-Cell Calcyfing Sertoli-Cell Tumor (LCCSCT). This mutation promotes aromatase overexpression in neoplastic Sertoli-cells, leading to gynecomastia.Case present...

Beckwith-Wiedemann Syndrome (BWS) is an overgrowth disorder, occurring in 1/13,700 births. BWS is usually sporadic, but 15% of cases are familial. Variable phenotype may include overgrowth, macroglossia, abdominal wall defects, neonatal hypoglycemia, lateralized overgrowth and predisposition to embryonal tumors. We describe three male cases of BWS followed at our clinic.Case 1: Born of a gestation complicated by gestational diabetes. Del...

Background: In 2011, ATA and AACE published Guidelines on pediatric Graves’ disease (GD) treatment. Nevertheless it is still a controversy.Objective and hypotheses: SPEDP conducted the first nationwide questionnaire survey among all the Endocrinologists and Pediatricians in the Portuguese Public Health System Hospitals about pediatric GD treatment in order to know the reality in our country.Method: SPEDP designed and distribut...

Precocious Puberty is defined by the onset of pubertal development at an age 2-2,5 standard deviations earlier than the normal population. Central Precocious Puberty (CPP) is diagnosed when the hypothalamic-pituitary axis is activated. Gonadotropin-releasing hormone analogues (Gn-RH analogues) are the main treatment option, but sometimes controversial. Whether this treatment influences children's body mass index (BMI) and a different BMI progression is still unclear.<p...

Introduction: Nelson’s syndrome is a potentially severe complication of bilateral adrenalectomy, a radical procedure performed in the treatment of hypercortisolism in Cushing’s disease (CD). We report a case of CD in pediatric age submitted to bilateral adrenalectomy with subsequent Nelson’s syndrome.Case report: Male, 5-year-old, referred to a Pediatric outpatient clinic because of growth failure, rapid weight gain and high blood pressure...

Objective: Central precocious puberty (CPP) is a common condition in pediatric endocrinology practice. Gonadotropin-releasing hormone agonists (GnRHa) treatment is safe, but the real effect on final height and the ideal timing for treatment remains controversial. The purpose of the authors was to evaluate a nationwide representative group of CPP Portuguese girls treated with GnRHa, assess the effectiveness of treatment and the growth outcome before and after 8...

Introduction: No consensus on vitamin D (VitD) deficiency screening in children and adolescents exists.Aim: To evaluate a sample of patients in whom VitD dosing was performed and determine the rationale for this assessment.Methods: Retrospective, longitudinal study of pediatric patients, from a Portuguese tertiary hospital, who had at least two 25(OH)D level blood sampling between ...

Introduction: Vitamin D (VitD) is a prohormone that is synthesized in the skin after sun exposure. Mandatory lockdown during the COVID-19 Pandemic may have altered the sun exposure time of children.Aim: to evaluate vitD levels in a sample of children and adolescents, and compare between pre-pandemic and pandemic periods.Methoths Children and adolescents, from a Portuguese tertiary ...
