Background: Actual surgical procedures for the treatment of patients with VSD (Variation of Sex Development), in particular severe hypospadias, are associated with frequent post-operative complications.Objective and hypotheses: Tissue engineered collagen tubes are a promising alternative.Method: We elaborated a new, two layered, collagen based tube that can be sutured. Mechanical testing proved a better resistance of those tubes co...

Background: The onset of puberty is influenced by the interplay of stimulating and restraining factors, many of which have a genetic origin. Premature activation of the GnRH secretion in central precocious puberty (CPP) may arise either from gain-of-function mutations of the KISS1 and KISS1R genes or loss-of-function manner mutations of the MKRN3 gene leading to MKRN3 deficiency.Objective and hypotheses: Explore the genetic cau...

Background: The primary goal of treatment is to achieve a final height within the normal range and avoid the physical and psychological consequences of short stature (SS). If after a time, treatment efficacy criteria are not achieved, it is necessary to revalue its usefulness. There is no consensus about which conduct should be adopted in these cases. An alternative, is the suspension of rhGH treatment and evaluate the clinical and biochemical results to decide to continue or ...

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: Recent clinical guidelines recommend that all patients with non-classic congenital adrenal hyperplasia (NCCAH) on glucocorticoid therapy (GC) need to be informed about stress doses and suggest the use of GC in the subgroup of patients with low cortisol response during periods of stress even though they are not on GC.Objective and Hypotheses: To study the response of cortisol to ACTH 250 μg i.v. (Synacthen®, Novartis) in p...

Background: Infantile obesity is nowadays a pandemic disease and needs a paediatrician interventional attitude. Since 1990 until 2010 it has trebled and the World Health Organization recommends prevention ‘as soon as possible’ even during the first year of life. A Spanish study (Aladino 2011) stimated the prevalence of overweight in boys as a 26.3% and in girls a 25.9% and the prevalence of obesity as a 22% and a 16.2% respectively. Our aim was to set up a new score ...

Background: Foramen magnum stenosis (FMS) is a life-threatening complication in children with achondroplasia (ACH) which may require cervicomedullary decompression (CMD). There is no evidence if FMS and CMD affects growth in children with ACH.Aim: To evaluate the impact of FSM and CMD surgery on anthropometric measurements in children with ACH.Methods: Sixty-five patients with ACH ...

Background: Studies have suggested that sirolimus might be diabetogenic, mostly in kidney transplant recipients. Sirolimus has now been shown to be effective in the management of patients with congenital hyperinsulinism (CHI). However to date, there are no publications regarding the diabetogenic effect of Sirolimus in CHI patients.Objective and hypotheses: To report the first case of sirolimus precipitating diabetes in a CHI patient with known genetic mu...

Children born small for gestational age (SGA) not showing catch-up growth in the first two years of life may show decreased growth rate and adult height, as well as worse metabolic profile, compared to general population. In these patients, growth hormone (GH) treatment is recommended, showing positive effects on both growth rate and metabolic profile, with good tolerability. The aim of the current study was to evaluate the auxological and metabolic effects and the safety of G...

Systemic Juvenile Idiopathic Arthritis (sJIA) is a chronic autoinflammatory disease, with significant complications that can give short-term and long-term disability with reduced quality of life. Growth delay and short stature are described in >40% of cases, with a complex pathogenesis. Chronic inflammation, long-term corticosteroids treatment, hepatic involvement, malnutrition decrease IGF-1 and GH biological effects. Corticosteroids inhibit growth velocity, bone maturatio...
