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...

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...

Background: Subclinical hypothyroidism (SH) is defined as normal tyrosine levels in the presence of TSH concentrations between 5 and 10 mU/ml. The impact of SH on IGF system and growth of infants remains unknown.Objective and hypotheses: To evaluate IGF1, IGFBP3 levels and growth velocity (GV) of infants with SH.Method: 98 children up to 36 months of age, recalled due to a TSH >5 mU/ml in the neonatal screening test, were divid...

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...

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...

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...

Background and aims: The introduction of next-generation sequencing (NGS) as an essential tool for the routine molecular diagnosis of DM has highlighted the under-diagnosis of monogenic diabetes mellitus (MonDM). Accurate molecular diagnosis of the MonDM subtype has important implications for prognosis and choice of treatment, family counseling and health management, enabling precision medicine. The main objective was to clinically and molecularly characterize...

Introduction: Diabetic ketoacidosis (DKA) is a potentially fatal hyperglycemic emergency primarily associated with type 1 diabetes mellitus (T1D). The association between DKA and severe hypertriglyceridemia has already been previously discussed with a prevalence ranging between 7.1%-25%, with pancreatitis present in the majority of cases. Epidemiological data in the pediatric age are scarce and not well established. Its etiology is not yet fully known. The &qu...

Growth Hormone deficiency (GHD) in newborn is an infrequent condition, which can cause threat to life due mainly to hypoglycemia that begins in the first week of life. A GH basal level (whether random or associated with spontaneous hypoglycemia) that distinguishes infants with GHD from those with GH sufficiency in the neonatal period is not conclusive. Few data have been reported about the GH measurements in serum and dried blood spots on filter paper samples in healthy neonat...

Background: Isolated growth hormone deficiency (IGHD) is a relatively common disorder. Current diagnostic protocols require a brain MRI of the hypothalamus and the hypophysis after establishment of the diagnosis, with the aim of identifying structural defects and specifically rule out an underlying space-occupying lesion. An MRI scan is costly and requires general anesthesia in young children. Data on the contribution of brain MRI in diagnosing children with I...
