Effects of IGF-1R Nuclear Localization in Glioblastoma Cells

Martin Ayelen , Clement Florencia , Venara Marcela , Bergada Ignacio , Gutierrez Mariana , Pennisi Patricia

Background: CNS tumors 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. Recently, we have shown that in paediatric gliomas, IGF-1R nuclear localization was significantly associated with both high grade tumours and increased risk of death, suggesting that nuclear IGF-1R localization may contribute to an aggressive behaviour of these tumours.<p class="...

Dumitrescu Cristina , Gherlan Iuliana , Radomir Lidia , Vintila Madalina , Brehar Andreea , Caragheorgheopol Andra , Purice Mariana , Procopiuc Camelia

Turner Syndrome (TS) is a relatively common chromosomopathy and according to epidemiological studies the prevalence of Autoimmune thyroiditis (AIT) in TS fluctuates from 10% to 21% versus 1.3% in the general population.Objective: – to retrospectively evaluate thyroid autoimmune disorders and thyroid function in a group of 93 TS patients.– to compare the prevalence of AIT and thyroid dysfunction in subgroups of TS accordin...

Delayed Puberty: Between Chronopathology and Subclinical Pathology

Procopiuc Camelia , Dumitrescu Cristina , Gherlan Iuliana , Brehar Andreea , Costache Mariana , Procopiuc Livia , Caragheorgheopol Andra

Background: At 14 years of age for boys and 13 years for girls, delayed puberty with low gonadotropic hormones can either be a chronopathologic feature (constitutional delay of puberty – CDP) or the subclinical unmasking of a future isolated hypogonadotropic hypogonadism (IHH). The two conditions are difficult to differentiate at these specific ages.Objective and hypotheses: We aimed to identify clinical and paraclinical features which correlate wit...

Resistance to Thyroid Hormone Syndrome from Childhood to Adulthood: Variation in Symptoms and Thyroid Function

Garrahy Aoife , Grace Mariana , Stapleton Mary , Moran Carla , Chatterjee Krishna , Murphy Matthew , O'Connell Susan

Introduction: Resistance to thyroid hormone (RTH) is a rare autosomal dominant condition characterised by tissue-specific insensitivity to thyroid hormone. In 85% of cases the disorder is associated with thyroid hormone receptor β (TRβ) gene mutations.Case report: A 2.6-year-old boy was referred to the Paediatric service with abnormal thyroid function tests (TFTs) (fT4 30.4 pmol/l; RR 12–26, fT3 10.2 pmol/l; RR 3.7&#1...

Malaquias Alexsandra , Moraes Michelle , Funari Mariana , Pereira Alexandre , Bertola Debora , Jorge Alexander

Objective: To evaluate the response to recombinant human GH (rhGH) treatment in NS children with short stature and previously identified mutations in the RAS/MAPK pathway genes.Methods: 23 patients with NS (17 males; 19 PTPN11, 3 RAF1 e 1 SHOC2) were daily treated with rhGH (mean rhGH dose of 47 μg/kg per day). The main outcome measures were 1st year growth velocity, change in height SDS (Noonan syndrome specifi...

Primary hyperparathyroidism in a pediatric patient with tuberous sclerosis

Lucia Feller Ana , Mariana Aziz , Victor Ayarzabal , Ciaccio Marta , Gisela Viterbo

Introduction: Tuberous sclerosis (TS) is a rare, autosomal dominant, multisystem disease with a frequency of 1:6,000-10,000. It is caused by variants in the genes encoding hamartin (TSC 1) and tuberin (TSC 2) that normally act as inhibitors of the mTOR signaling cascade that regulates cell proliferation and migration, angiogenesis, and cell metabolism. The most frequent clinical presentation includes hypochromic macules, angiofibromas, hamartomas in the centra...

Clitoromegaly - Size does matter

Barash Galia , Ariella Brown Segal Malka , Neogolani Larisa , Bistritzer Zvi , Rachmiel Mariana

Background: A finding of an enlarged clitoris in a female newborn, raises the suspicion of abnormal sexual differentiation and the possibility of female virilization, most commonly due to CAH. This often leads to an extensive medical evaluation which can be painful, expensive, and stressful for the patient and her family. Medical literature does not provide accurate values of a normal clitoris size. According to the few studies available, the current norm rang...

Use of denosumab in aneurysmal bone cyst and giant cell tumor in a third-level pediatric center

Feller Ana , Aziz Mariana , Gil Silvia , Nader Julio , Bermejo Natalia , Soria Ianina , Ciaccio Marta , Viterbo Gisela

Introduction: Denosumab is a RANK-L inhibitory monoclonal antibody approved in adults for treatment of aneurysmal bone cyst (ABC) and giant cell tumor (GCT). Although it has shown to improve postsurgical morbidity and stop progression in unresectable forms, there is limited data to guide its use in growing patients, with reports of endocrinology disorders.Aim: Evaluate frequency, presentation and treatment of adverse eff...

Use of Automated Insulin Delivery systems (AIDs) in preschool children

de Beaufort Carine

Management of type 1 diabetes in preschool children is a huge challenge for their caregivers. Age-specific factors (e.g. unpredictable food intake and physical activity, small insulin doses, high insulin sensitivity, frequent intercurrent infections, high variability in insulin requirements) increase the complexity of daily diabetes management. Furthermore, the preschool child depends completely on his/her caregiver. To meet recommended treatment targets while avoiding hypogly...

Psychiatric Comorbidities in Transgender Youth

de Vries Annelou

I review the mental health difficulties that transgender and gender diverse children and adolescents may present with, specifically emotional difficulties. Many studies reveal depression scores and parent and self-reported measures of emotional and behavioral problems that are comparable to mental health clinic referred populations. Children and adolescents who feel that they are acknowledged and supported in their gender diverse feelings, e.g. by receiving gender affirming me...
