Introduction: Granulosa cell tumors (GSTs) of ovary are very rare, usually large gonadic neoplasms arising from the mesenchyme and sex cords. The main clinical appearance of the juvenile GCTs is represented of signs of excessive estrogen (Precocious puberty - 75% of cases) or testosterone secretion (rare).Aim: To present the different clinical presentation and outcome in a case series of a rare tumor patients.<p clas...

Positive Impact on Adherence Through Educational Activities of the Argentina´s Patient Support Program in Children with low Adherence to Treatment with Recombinant Growth Hormone (easypod applicator)

Assefi Aria Reza , Chareca Cinthia , Roca Fernanda , Rubstein Adrian , Ayala Luciana Celis , Von Schulz Hausmann Cristian

Background: One of the main concerns in patients with growth disorders is to achieve optimal adherence to growth hormone (GH) treatment. For this it is important to identify patients with low adherence to treatment and to evaluate actions to improve it.The Merck Patient Support Program (PSP) carried out educational actions aimed at patients with low adherence and their parents, to raise their awareness of the importance of good adherence...

Background: Isolated aldosterone synthase deficiency is a rare autosomal recessive disorder caused by pathogenic variants in CYP11B2. To date, more than forty different pathogenic variants in the CYP11B2 gene causing isolated aldosterone synthase deficiency have been identified. We report on a novel pathogenic CYP11B2 variant.Case report: The second child (male) of consanguineous, healthy parents, presented shortly after...

Background: Turner Syndrome (TS) with a 45,X phenotype is generally more severe than TS with mosaicism, but the potential role of the degree of mosaicism in modulating TS phenotype has never been investigated. We assessed the impact of various degrees of 45,X/ 46,XX mosaicism on phenotypic features in a cohort of TS patients.Method: We analysed a cohort of TS with 45,X/ 46,XX mosaicism (percentage mosaicism from peripheral blood lymphocytes, known in <em...

Background: The C3 epimer of 25-hydroxi-vitamin D3 (Epi25OHD3) is present in the pediatric and adult population and varies according to age. If it measurement is clinically relevant and should be considered to classify Vitamin D status is still unknown.Objective: To measure 25OHD3, 25-hydroxy-Vitamin D2 (25OHD2) and Epi25OHD3 and to compare them with PTH and calcemia.Method: Subjects: Children between 5 and 8 years of age born very...

Introduction: Pituitary stalk thickening (PST) is a rare condition in pediatric patients. As there are few studies published in pediatric population, the definition has been difficult to establish. The etiologies involved in PST can be divided in neoplastic, congenital, inflammatory/infectious or autoimmune diseases. In children the most frequent causes are neoplastic, followed by congenital lesions. The inflammatory/infectious and autoimmune diseases are rare...

The Easypod™ Connect Observational Study (ECOS) assessed real-time adherence in patients from 24 countries who were receiving recombinant human growth hormone (r-hGH; Saizen®) via easypod™, which is an electronic injection device. Overall, ECOS showed mean adherence was maintained at ~80% for up to 3 years. Here, we assess the adherence to r-hGH administered via easypod™ in the Argentinian cohort of patients from ECOS (NCT01582334).<p class="ab...
