Background: Mc Cune Albright (MAS), is a rare genetic disease clinically defined by bone fibrous dysplasia (BFD), café au lait skin spots and at least one hyperfunction endocrinopathy. Growth Hormone (GH) excess has been described in 20% of patients usually accompanied by hyperprolactinemia (80%). As reported in literature GH hypersecretion is allways associated with craniofacial BFD, macrocephaly and is also accompanied by higher risk of systemic...

Introduction: Leydig cell tumors are rare (3% of testicular neoplasms). 80% of cases occurs in adult population, although a quarter is described in prepubertal patients older than four years. The clinic differs according to the patient's age. Activating mutations, acquired and limited to the tumor tissue, are described in exon 11 of the LH receptor gene. And in mixed Sertoli-Leydig tumors activating mutations of the Gs-alpha subunit of the stimulat...

Puberty is a crucial biological process normally occurring at a specific time during the lifespan, during which sexual and somatic maturation are completed, and reproductive capacity is reached. Pubertal timing is not only determined by genetics, but also by endogenous and environmental cues, including nutritional and metabolic signals. During the last decade, we have learned much regarding the essential roles of kisspeptins and the neuropeptide pathways that converge on these...

Background and Aim: Gliomas are the most frequent solid tumors in pediatric population. The IGF system of ligands and receptors are known to play an important role in both normal and neoplastic growth. In a previous work we have reported the quantitation of some components of the IGFs system in SNC pediatric tumours (IGF-1, IGF-2, IGF-1R, IR), being IGF-2 expression the most variable among all the genes studied.Our aim w...

Introduction: The MAMLD1 gene is expressed in fetal and adult testes. It contributes to the development and formation of the male external genitalia in late stages of fetal organogenesis (week 8-12) and to testosterone biosynthesis. The pathogenic genetic variants of this gene determine a significant reduction in plasma testosterone concentrations, although they are not undetectable. Its most common phenotypic manifestation is hypospadias, also described in patients with micro...

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...

Introduction: Menarche is the time of first menstrual bleed and it occurs, on average, 2 to 2.5 years after the onset of puberty. Globally, the age of menarche had been reduced since the last century.Objective: To examine the evolution of the age of menarche over the last decades and inter-regional variability in an autonomous community located in northern Spain which is divided in eight health areas.<p class="abstex...

The congenital central hypothyroidism (CCH) incidence is estimated at 1:18,000-30,000 neonates and most are included in multiple pituitary deficiencies (MPD). Clinical depend on the etiology, the deficit severity; other associated hormonal alterations and the age of diagnosis. Neonatal screening (NS) for congenital hypothyroidism that includes T4 facilitate its diagnosis.Objetives: •To evaluate the characteristics of patients with C...

Background: Silver-Russell syndrome (SRS) is characterized by intrauterine and postnatal growth retardation, a typical phenotype and feeding difficulties. It is related to 11p15 ICR1 hypomethylation in up to 50% of the cases. Some patients may exhibit signs of early puberty or premature adrenarche, including premature pubarche and/or an exaggerated adrenarche (high dehidroepyandrosterone sulfate (DHEAS) levels for chronological age). Despite early feeding difficulties, some ch...

Background: Hashimoto’s thyroiditis is a common autoimmune disease in pubertal and adolescent girls. In the past years the incidence of this autoimmune disease of the thyroid gland has increased.Objective and hypotheses: We present a 12.5 year old girl who had her first visit at our Pediatric Endocrinology Department at the age of 10 years due to short stature and clinical signs of hypothyroidism. Her height was – 3SD SDS and her BMI was 12.7. ...
