Background: Obesity is a worldwide epidemic affecting adults and children. Social changes throughout history have contributed to modifications in nutrition and physical activity levels. These changes in lifestyle affected health, increasing the number of metabolic and cardiovascular diseases. Obese children already have a low grade systemic inflammation as well as markers of increased cardiovascular risk. The endothelial function is an important and early marker of atheroscler...

Introduction: About 15% of children born small for gestational age (SGA) do not reach final height within normal range. Recombinant human growth Hormone (rhGH) has shown to be effective in catching up growth velocity and height in children born SGA.The objective of our study is to identify the predictive factors of final height in children born SGA treated with rhGH.Materials and Methods: Monocentric, retrospective s...

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: Newborn (NB) screening programs show a wide variation in congenital hypothyroidism (CH) incidence along the years.Objective and hypotheses: To describe CH incidence, etiology, associated malformations and Down Syndrome (DS) in children detected by our NB Screening Program. To search differences between permanent CH (PCH) and transient forms (TCH).Method: We analyzed NB with positive screening results referred between A...

Background: Following a phase of feeding difficulties and underweight in early life, children with Prader-Willi syndrome (PWS) develop hyperphagia and a tendency towards severe obesity. Growth hormone therapy (GH) has been approved in PWS to compensate their growth failure but may exert also additional effects on muscle component and body composition as well.Objectives: We aimed to test if an early initiation of GH thera...

Background: Differentiation of the gonads in men is closely dependent on Sertoli cells maturation. Differences of sex development (DSD) are caused by variations in this process. The study of the mechanisms underlying these complex conditions is crucial for optimal clinical management and Sertoli cells would be an ideal model for this purpose. However, there are two main obstacles for the study of human Sertoli cells. Firstly, mature human Sertoli cells lose their proliferation...

Background: 2015 ATA Guidelines for management of medullary thyroid cancer (MTC) include C634 RET codon mutation in ‘High risk’ group, recomendating prophylactic thryroidectomy before 5 years old based on serum basal calcitonin levels (SBCt).Objective and hypotheses: We present 14 pediatric patients with C634 RET codon mutation, who underwent prophylactic thyroidectomy in our center, their clinical and analytical features and anatomopathologica...

Background: The most common form of congenital adrenal hyperplasia (CAH) is 21-hydroxylase deficiency, which in its severe form can cause genital ambiguity in females. This can be ameliorated by administering dexamethasone to the mother.Case: This is a family whose index case is a first son diagnosed by Madrid Newborn Screening Program of CAH with salt-wasting form due to 21-hydroxylase deficiency. Mutation analysis revealed: ‘hybrid deletion’ ...

Background: TSH cut-off (CO) levels has been lowered progressively in many screening programs. Nevertheless, population detected with lower CO levels differs in severity and etiology.Objective and hypotheses: To describe the etiological characteristics and severity of children detected by neonatal screening related to CO TSH levels.Method: We analysed the data of congenital hypothyroidism (CH) neonatal screening performed between J...

Background: Hypercortisolism due to PPNAD may be cyclical, atypical and may develop suddenly or progressively.Objective and Hypotheses: The performance of salivary cortisol (SF) in this rare cause of Cushing’s syndrome (CS) is lacking.Method: Ten patients (nine F/one M) with PPNAD (two sporadic; eight Carney complex) were evaluated. Among these, six had CS family history, while in two the diagnosis was confirmed by germline PR...
