Background: Data on the neuroradiological findings in Noonan syndrome (NS) are limited.Study Design and participants: Multicentric retrospective observational study conducted in 9 Italian centers of Pediatric Endocrinology. Population includes 112 patients (62 males, 50 females; 73 PTPN11, 8 KRAS, 8 SOS1, 4 LZTR1, 4 RIT1, 4 SHOC2, 3 BRAF, 2 RAF1, 1 ERF, 1 HRAS, 1 MAP2K1, 1 MEK1, 1 PPP1CB, 1 RASA1) with diagnosis of NS ge...

We describe a 5 years-old patient referred to our centre for dysmorphic features and delayed psychomotor development. Negative family history, second child, full-term birth, eutocic delivery, regular growth parameters at birth and neonatal adaptation. Autonomous walking at 20 months with clumsiness; first words at 2 years with dysarthria and dysphagia. Brain MRI and array-CGH were normal. At the neurological examination: perioral hypotonia, sialorrhea, praxic difficulties. At ...

ERF protein is a major binding target of ERK1/2 kinases, key effectors of the RAS–MEK–ERK signaling cascade. ERF has a role as a negative transcriptional regulator of RAS/MAPK mitogenic pathway (1) and, in theory, a loss-of-function mutation (LOF) in ERF could cause a Rasopathy phenotype. To date, LOF variants of ERF have been reported in 45 individuals with craniosynostosis but without a Noonan-like phenotype. There is only one case report describing a patient wit...

CHOPS syndrome is a rare monogenic disorder caused by heterozygous gain-of-function variants in AFF4. The 13 patients reported to date share a highly recognizable phenotype: Coarse face, Cognitive impairment, Heart defects, Obesity, Pulmonary involvement, Short stature and Skeletal dysplasia. AFF4 encodes a scaffold protein involved in transcriptional elongation and critical for gene expression regulation during embryogenesis. Notably, it appears to regulate adipogenic differe...

Hashimoto encephalopathy is an autoimmune encephalopathy predominantly diagnosed in the adult population. In the pediatric population, the mean age is determined to be 14 years, with the majority of adolescent females. The diagnosis of Hashimoto encephalopathy is clinical and based on the highly variable neuropsychiatric conditions, often affecting more than one area of the central nervous system, the detection of antiperoxidase or antithyroglobulin antibodies in serum, and on...

Objective: Linear growth is impaired in children with type 1 diabetes (T1D) and poor metabolic control. A good metabolic control is a key therapeutic goal to prevent vascular complications but also for ensuring an appropriate anthropometric development during childhood. In this study, we aimed to identify and characterize the effects of glycemic variability on linear growth in children with T1D.Methods: Data from 144 pre...

Background: COVID-19 restriction measurements have enhanced the obesity status in the pediatric population which might further contribute to obesity related glucose-insulin metabolism alterations. Therefore, we retrospectively compared anthropometric and OGTT data on obese children during the 13 years before and during the COVID-19 pandemic period.Subjects/Methods: Data from 741 obese/overweight children were retrieved a...

Introduction: Growth Hormone Deficiency (GHD) represents the most common hormone deficiency during childhood accounting for 3% of causes of short stature. Although growth hormone (GH) replacement therapy is available, several studies have shown a different response in terms of height. Therefore, some reports have tried to characterize predictive factors able to define growth gain during treatment.Objective: Therefore, th...

Background: Metabolic Syndrome (MS) represent a common dysmetabolic state in obese children and adolescents. Although data in youth show a role of gut hormones in the risk of developing MS, no data are available during the prepubertal age, especially across clusters of MS.Objective: Thus the aims of this study were to evaluate components of the MS in prepubertal obese children compared to controls and to characterize cha...

Background: Hypothyroidism may be also a rare cause of acquired hypoceruloplasminemia. It has recently been underlined a role for thyroid hormone in the normal developmental regulation of ceruloplasmin (cp).Case presentation: A 3-year-old Caucasian girl was admitted to our clinic for recurrent pericarditis, fatigue and muscle weakness. Her family history was remarkable for Hashimoto’s thyroiditis and Graves disease. Her recent personal history was s...
