Background: Disorders related to an impairment in parathyroid hormone (PTH) signaling pathway are historically classified under the term pseudohypoparathyroidism (PHP), that now encompasses rare, related but highly heterogeneous diseases with demonstrated (epi)genetic causes. The actual classification is based on the presence or absence of specific clinical and biochemical signs together with an in vivo response to exogenous PTH and an in vitro assay of Gs&#9...

Pseudohypoparathyroidism (PHP) and related disorders lead to a wide spectrum of abnormal physical characteristics, neurocognitive and endocrine abnormalities. PHP (including all subtypes), pseudoPHP, acrodysostosis and progressive osseous heteroplasia refer to heterogeneous disorders characterized by physical findings, differently associated in each subtype, including short bones, short stature, stocky build, subcutaneous ectopic ossifications, as well as laboratory abnormalit...

Introduction: Primary hypothyroidism is the most frequent thyroid disease in children, and elevation of serum TSH is a common presenting complaint (pc) in the pediatric endocrinology outpatient clinic. Subclinical hypothyroidism (sHT) predominates in relation to overt hypothyroidism (cHT). The benefit of Levothyroxine is controversial specially when serum TSH levels are less than 10 uUI/ml.Objectives: To evaluate the pre...

Background: Increased incidence of obesity is related to increased consumption of fast and processed food and decreased consumption of fruits and vegetables.Objective and hypotheses: Evaluate the habit of fruit and vegetable consumption in children with overweight.Method: A questionnaire was designed in which the frequency and quality of these habits were recorded and anthropometric data also. Parent’s habits regarding fruit a...

Introduction: Adrenarche is characterized by the activation of androgen precursors which are released from the zona reticularis of the adrenal gland. Dehydroepiandosterone (DHEA) is a weak androgen and its conversion to slightly more potent androgens such as Dehydroepiandosterone- sulfate (DHEA-S) is thought to be responsible for the clinical signs of adrenarche. Premature adrenarche is one of the most common endocrine abnormalities causing concern among perip...

Introduction: Primary osteoporosis are frequently linked to syndromic conditions such as osteogenesis imperfecta which also involves extra esqueletic tissues. With the advancement of medicine, this group has been reduced, due the ability to specifying the causal pathogenic variants. Among these, the LRP5 (Low-density lipoprotein receptor-related protein 5) gene mutations are the most frequent cause. LPR5 is a fundamental coreceptor in the wnt/betacatenin signa...

Background: Paediatric nephrotic syndrome has an estimated incidence of 2 per 100,000 children per year and type 1 diabetes had a reported incidence of 9.5 per 100,000 habitants in Portugal (2018 data). To the best of our knowledge, the simultaneous occurrence of nephrotic syndrome and type 1 diabetes is rare – we found 13 published cases in paediatric age worldwide. Clinical case: A 5-year-old boy with personal history of nephrotic syndrome was admitted ...

Background: Hypothalamic hamartomas(HH) are rare heterotopic congenital malformations causing central precocious puberty(CPP) and/or resistant epilepsy whose natural history is unknown.Aim: To describe clinical and imaging features, and the risk of developing endocrine deficits, particularly after surgery.Method: Retrospective case note and imaging review of all HH diagnosed by MRI between 30.08.1991 and 24.11.17, analysed by initi...

Introduction: Central precocious puberty (CPP) at a very early age is usually caused by an organic lesion. The most common organic cause of CCP is the hypothalamic hamartoma (HH), which, associated with polysyndactyly, cleft palate and gelastic crises, clinically suggests the diagnosis of Pallister Hall Syndrome.Case: Infant 3-month-old woman with no family history. Polydactyly in hands and feet is evident from the second trimester of pregnancy. Born at ...

Background: Fear of hypoglycemia is a major constraint on achieving a good metabolic control in T1D. Sensor augmented insulin pump therapy with threshold-suspended features (MiniMed 640G-SG) might alleviate burden of hypoglucemia and improve outcomes.Objective and hypotheses: Evaluate the effectiveness of this system to prevent day and night hypoglycemia and its impact on HbA1c in a pediatric population with T1D.Method: Descriptive...
