Background: The phenotypic spectrum of short stature homeobox-containing gene deficiency disorders (SHOX-D) ranges from non-specific short stature to Leri-Weill dyschondrosteosis. Current guidelines support rhGH in SHOX-D children, but long-term data are still lacking. Moreover, no correlation has been established yet between the severity of phenotype, including the response to rhGH, and the underlying SHOX pathogenic variant.Aims: To ev...

Introduction: It is known that excessive gestational weight gain can cause an adverse intrauterine environment and increase the risk of cardio-metabolic diseases in the offspring. Epigenetics could be one of the mechanisms involved in this regulation.Objective: We aimed to study the DNA methylation profile of umbilical cord tissue that is associated with gestational weight gain (GWG), and its relationship with cardio-met...

Background and Aims: Gestational obesity can cause metabolic programming in the offspring. Epigenetic modifications of DNA have been suggested as potential mechanisms underlying this programming. FRAT-1 is a gene involved in the WNT signaling pathway, which is an important regulator of adipose tissue development. The objective of this work was to study the methylation status of FRAT-1 in placentas of women with either normal weight or gestati...

Background: ROHHAD/ROHHADNET syndrome (rapid-onset obesity with hypothalamic dysfunction, central hypoventilation, autonomic dysregulation with or without neural tumor - NET) – has been reported in association with cerebral venous thrombosis events, as reported also in central hypoventilation syndrome. It is not clear whether thrombotic risk represents a cause or a consequence of hypoventilation and hypothalamic dysfunction. Aim of our study was to chara...

Mosaic variegated aneuploidy (MVA) syndrome represents a rare autosomal recessive disease characterized by aneuploidies with gain and loss of multiple chromosomes. We describe case of two Moroccan brothers with MVA2, due to CEP57 mutations. Patients are 17 and 13-year-old male siblings of a Moroccan healthy consanguineous couple. Oldest brother was delivered at 35 gestational weeks after IGR diagnosis, small for gestational age (SGA, 1300 grams, -3 SDS). Younger patient’...

Six-year-old female, diagnosed with GH deficiency at another Center (H: -3.13SDS; H peak with clonidine 5.7ng/mL, with insulin 1.2ng/mL). Brain MRI at diagnosis: small pituitary gland, ectopic neurohypophysis, normal stalk, right internal carotid artery aplasia. At 10 years onset of polyuria-polydipsia syndrome (PPS) (4L/day–154ml/kg/die); mood disorders and ADHD diagnosis were also reported. A fluid deprivation test was performed, lasting 22 hours (pre: S-Osm 275mOsm/L,...

Introduction: About 25% of children and adolescents with Type 1 Diabetes (T1D) have one or more associated autoimmune conditions. Although Graves' disease (GD) rarely occurs, considering the potential severity of manifestations, an early diagnosis and appropriate treatment are essential. The first line treatment is methimazole, whose use is not free from side effects; therefore, it is important to start with the most appropriate dosage.<p class="abste...

Although craniopharyngiomas are low-grade tumours, long-term survivors frequently suffer from severe morbidity due to hypothalamic lesions, such as hypothalamic obesity, that is largely resistant to lifestyle modification and pharmacotherapy. We investigated the efficacy of bariatric surgery in two patients with craniopharyngioma-related hypothalamic obesity during 18 months of follow-up. Patient n1, diagnosed with craniopharyngioma and treated with complete surgical excision ...

A 5-years-old boy was admitted because of polydipsia and polyuria. His family history was unremarkable. After water deprivation test (10h), laboratory test showed high levels of serum sodium (150.1 mmol/L), low urine osmolarity (88 mOsm/kg) and high serum osmolarity (301 mOsm/kg) consistent with the diagnosis of central diabetes insipidus (CDI). He started therapy with oral desmopressin with clinical improvement. Brain MRI revealed pituitary stalk thickening (3 mm), no hyperin...

Children diagnosed with adrenocortical tumors (ACT) have variable prognosis depending on disease presentation at diagnosis. Available therapeutic options render excellent outcome for a subset of patients, but limited improvement in the survival of those diagnosed with non-localized/advanced disease. ACT DNA methylation was recently demonstrated to be a robust and independent prognostic biomarker. Aiming to identify potential therapeutic targets for these children, we compared ...
