Effect of Adjunctive Therapy with Cholecalciferol on Residual β-Cell Function in Recent-Onset Type 1 Diabetes Mellitus: a Prospective Pilot Study

Fitas Ana Laura , Almeida Ana Filipa , Limbert Catarina , Lopes Lurdes

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...

Final Height in Congenital Adrenal Hyperplasia: A Retrospective Study

Martins Mariana , Reis-Melo Ana , Espada Filipa , Fonseca Marcelo

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.</...

Gynecomastia with Precocious Onset in Peutz-Jeghers Syndrome: Managing the Aromatase Overexpression

Simoes-Pereira Joana , Marques Ana Filipa , Limbert Catarina , Lopes Lurdes

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...

Marques Olinda , Joao Oliveira Maria , Antunes Antunes Ana , Espada Filipa , Guimaraes Joana

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...

Changes in the Body Mass Index in Children with Central Precocious Puberty' Under Gonadotropin-Releasing Hormone Analogue Treatment - A Multicentric Study

Galo Elisa , Leite Ana Luisa , Antunes Ana , Robalo Brígida , Espada Filipa , Castro Sofia , Dias Sara , Limbert Catarina

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...

Nelson’s Syndrome after Bilateral Adrenalectomy for Cushing’s Disease in Pediatric Age – Report of a Case

Machado Catarina M , Leite Ana L , Sousa Ana , Almeida Lucia , Campos Rosa Armenia , Oliveira Maria Joao , Marques Jorge Sales

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...

Normosmic Hypogonadotropic Hypogonadism: An Intrafamiliar Case

Soares Joana , Briosa Filipa , Valsassina Rita , Amorim Marta , Limbert Catarina

Background: Idiopathic hypogonadotropic hypogonadism (IHH) is due to the failure of gonadotrofin releasing hormone (GnRH) secretion which impairs the physiological initiation of puberty. About 30 to 50% of IHH is associated to hereditary causes and about 50 mutated genes have been identified.Objective and methods: We present three intra-familial cases of normosmic IHH (nIHH) related to a new association of two hetero...

Cardiovascular Risk Factors in Children and Adolescents with Type 1 diabetes

Ferreira Carla , Ferreira Helena , Correia Filipa , Meireles Carla

Background: Diabetics have an increased risk of cardiovascular disease. In young adults with type 1 diabetes mellitus (T1DM), cardiovascular events are more often the cause of premature death than nephropathy. In pediatric T1DM population, 35% have 2 or more cardiovascular risk factors (cvRF).Objective and hypotheses: This study aimed to determine the prevalence of traditional cvRF in children and adolescents with T1DM, and their association with the deg...

Anastrozole improves height prediction and near final height as monotherapy or in combination with growth hormone

Machado Pinto Renata , de Almeida Debora Ribeiro , Vitor Percussor Silva Joao ,

Introduction: The wide aromatization of androgens during puberty is responsible for the rapid bone maturation at this age. In this context, the use of aromatase inhibitors (AIs) has been justified by the potential to slow down the advancement of bone age and thus improve growth. For more than two decades, studies have pointed out the validity of AIs to improve the predicted final height (PFH). However, data on near-final height (NFH) of children treated with A...
