Introduction: Vitamin D deficiency in children is still a global health problem. Measuring free 25-hydroxyvitamin D concentrations could provide a better estimate of the vitamin D status than total 25-hydroxyvitamin D (25(OH)D) levels.Objective: To assess the relationship between measured free vitamin D (m-f25(OH)D) and calculated free 25(OH)D (c-f25(OH)D), total 25(OH)D, intact parathyroid hormone (iPTH) and other markers of phosphocalcic metabolism. Es...

Objective: Acute adrenal crisis is one of the main concerns in children with classic congenital adrenal hyperplasia (CAH). The aim of this study was to evaluate hypoglycemic and salt-wasting episodes in children with an established diagnosis of classic 21-hydroxylase deficiency (21-OHD) after start of treatment.Methods: A retrospective observational study was conducted for 85 patients with classic CAH (68 salt-wasting and 17 simple virilizing), aged 1 to...

Background: X-linked Congenital Adrenal Hypoplasia (AHC) is a rare cause of primary adrenal insufficiency due to mutations in NR0B1 gene, causing a loss of function of the nuclear receptor protein DAX-1. Adrenal insufficiency usually presents in the first two months of life, but sometimes can appear later in childhood. Hypogonadotropic Hypogonadism is often associated later in life and all patients develop azoospermia. We describe an unusual onset of AHC started with ...

Background: Development of cystic fibrosis–related diabetes (CFRD) is associated with worse pulmonary function, poorer nutritional status, more chest infections and increased mortality. In cystic fibrosis (CF) patients, abnormality of the 1 hour glucose during Glucose Tolerance test (GTT) is reported to be a better predictor of early CFRD and is associated with decline in pulmonary function compared to the 2-hour glucose level during GTT. We report a case series of 4 pati...

Introduction: Term newborns Small for Gestational Age (SGA) have an increased risk for minor neurological impairment at pre- and school age. The general movements (GMs) assessment, in particular at Fidgety (F+) age, has been increasingly used to predict neurological dysfunctions. Aim of our study was to evaluate, in a population of term newborn SGA (gestational age >37 weeks) the growth recovery, the presence of F+ at 3 months of age, and the neurological outcome at 2 year...

Introduction: Short stature is frequently associated to neurofibromatosis (NF). In these patients this condition is often caused by growth hormone (GH) deficiency. We describe four boys affected by NF type 1 and GH deficiency treated with GH replacement therapy.Case report: GH deficiency was diagnosed in four patients with NF type 1, who were referred to our Pediatric Endocrinology Unit for short stature. Patient 1 started GH replacement therapy at the C...

Background: Small for gestational age (SGA) children are at increased risk of metabolic syndrome in adulthood and have below-average bone mineral density (BMD). Growth hormone treatment reduces fat mass and insulin sensitivity, increases lean body mass and improves height and BMD in short SGA children. We aimed to evaluate changes in body composition in SGA patients treated with growth hormone (GH), after its cessation, compared with young adults born appropriate for gestation...

KBG syndrome (OMIM 148050) is a an emerging autosomal dominant disorder caused by heterozygous mutations in the ANKRD11 gene or deletions of 16q24.3, characterized by developmental delay, short stature, dysmorphic facial features and skeletal anomalies. Patients and methods: We report 22 patients with dysmorphic features, learning disabilities, behavior problems and macrodontia, where a clinical diagnosis of KBG was suspected. An ANKRD11 defect was confirmed in 12 patients. In...

The LMNA gene encodes lamin A/C, intermediate filament proteins associated with the inner nuclear membrane. Mutations in LMNA gene cause a wide range of human diseases sometimes called ‘laminopathies’ that affect different organ systems depending upon the mutation. Most laminopathies involve tissue of mesenchymal origins, resulting in such features as cardiac disorders and/or muscular dystrophy, lipodystrophy or progeroid syndromes. The group of progeroid syndromes i...

Introduction: Kabuki syndrome (KS) is a rare genetic disorder (1 in 32,000 newborns) caused by mutations in the KMT2D gene (autosomal dominant pattern) or the KDM6A gene (X-linked dominant inheritance). KS is characterized by distinctive facial features including arched eyebrows, long eyelashes, long palpebral fissures with everted lower lids at the outside edges, flat, broadened tip of the nose and large protruding earlobes. The name of this disorder comes from the resemblanc...
