Background: There is no effective adjuvant therapy for patients with advanced ACT. YAP1, a HIPPO pathway effector, interacts with Wtn\beta-catenin pathway and plays a crucial role in the maintenance of postnatal adrenal cortex and regulates cell proliferation and apoptosis in several tissues. We recently showed that overexpression of YAP1 associates with worse prognosis in our cohort of pediatric ACT (pACT).Aim: To analy...

Background: Small birth size followed by accelerated weight gain in early life is associated with an increased risk for age-associated diseases, such as cardiovascular disease (CVD) in later life. The underlying causes for this are largely unknown. Leukocyte telomere length (LTL) is a marker of biological age and short LTL is associated with increased CVD-risk. Subjects born small for gestational age (SGA) who remain short are treated with growth hormone (GH) to improve adult ...

Background: Subjects born preterm have an increased risk for ageing-associated diseases such as cardiovascular disease (CVD) in later life but the underlying cause is largely unknown. Telomere length (TL) is a usable index for ageing, with shorter TL indicating older biological age. Furthermore, short TL is associated with CVD.Objective and hypotheses: To investigate TL in subjects born preterm compared to term and to assess if TL is associated with risk...

Introduction: X-linked hypophosphatemia (XLH), due to PHEX mutation, is the most common genetic form of rickets in children. This rare disease is characterized by decreased tubular reabsorption and increased renal loss of phosphorus due to increased FGF-23 levels. In children, XLH is often manifested by short stature, rickets and bowel limbs deformity. Conventional treatment with oral phosphorus salts and calcitriol is not always well tolerated which has a pro...

Background: Idiopathic short stature (ISS) is a term used to describe a group of short children for whom no precise etiology has been identified. Many children - if not the majority - referred with short stature are designated ISS. We report the case of a child with idiopathic short stature receiving off-label therapy with recombinant human growth hormone (rhGH). GH treatment showed significantly good results at short and long-term follow-up.<p class="abst...

Background: PSIS results in thin or absent pituitary stalk, adenohypophysis hypoplasia or aplasia, and ectopic neurohypophysis, confirmable by MRI. PSIS is a common cause of panhypopituitarism, often presenting with hypoglycemia in infancy or growth failure in childhood. Patients can present variable degrees of pituitary hormone deficiency and a large spectrum of clinical manifestations. Here, we report a unique case of PSIS presenting with absence of secondar...

Background: Neonatal diabetes (ND) is a rare monogenic form of diabetes presenting within the first six months of life. The most frequent causes include mutations in KCNJ11, ABCC8 and insulin genes, but up to 40% of patients remain without a molecular genetic diagnosis.Case presentation: Case 1: a female newborn of non-consanguineous parents, born at 35 weeks, SGA. She presented with hyperglycemia at second day of life...

Introduction: Nelson’s syndrome is a potentially severe complication of bilateral adrenalectomy, a radical procedure performed in the treatment of hypercortisolism in Cushing’s disease (CD). We report a case of CD in pediatric age submitted to bilateral adrenalectomy with subsequent Nelson’s syndrome.Case report: Male, 5-year-old, referred to a Pediatric outpatient clinic because of growth failure, rapid weight gain and high blood pressure...

Background: 16p11.2 microdeletion is most common chromosomal anomaly associated with syndromic obesity. The presence of a large number of flanking segmental duplications/low-copy repeat sequences with a high degree of sequence identity in the short arm of chromosome 16 (16p) leads to recurrent deletions and duplications as a consequence of non-allelic homologous recombination. A recurrent 600kb microdeletion is one of the most frequent genomic imbalances in 16...

Background: Melanocortin 4 receptor (MC4R) deficiency is the commonest monogenic form of non-syndromic obesity. MC4R is a seven transmembrane G-protein coupled receptor implicated in central regulation of body weight. The loss-of-function mutations in MC4R gene will contribute to early-onset obesity associated with hyperinsulinemia, hyperphagia and “binge eating”. We aim to determine the prevalence of MC4R variants in a Pediatrics...
