Background: The replacement therapy with levo-thyroxine (LT4) in congenital hypothyroidism (CH) aims to ensure normal growth and neuropsychological development. Few data are available about the appropriate dose during childhood and early adolescence.Objective and hypotheses: i) To evaluate LT4/kg per day requirement from diagnosis until 12 years of age; ii) to assess any differences in relation to the different etiology of CH as concern...

Background: Linear growth in patients with congenital hypothyroidism (CH) born in 1970s and 1980s is reported normal.Objective and hypotheses: To evaluate whether the earlier diagnosis and the higher L-T4 starting dose lead to an improvement in growth and pubertal outcome over the last two decades.Method: Two-hundred and fifteen patients with permanent CH born in 1980s and 1990s (age at diagnosis 25.1&#177...

A 8 years and 7 months old male presented with short stature related to his target height. No history of bones fractures. The patient was 120.7 cm (- 1.77 SDS). Physical exam demonstrated peculiar facies, relative macrocephaly, delayed tooth eruption and pectus carinatum. He referred during the clinical evaluation diffuse bone pain and weakness, mostly exacerbated by sport activity. A first diagnostic investigation had already been made showing low serum alkaline phosphatase a...

Background: Klippel-Trenaunay-Weber syndrome is characterized by a triad of port-wine stain, venous malformation, and bony and soft tissue hypertrophy. Most patients would have two out of the three features. It is a rare disorder occurring in one out of 100000 live births. Diagnosis is largely clinical. The cause is unknown but could be due to a sporadic genetic mutation. Management is conservative.Objective and hypotheses: We report a case of a 4month-o...

Background: Multiple Endocrine Neoplasia type 1 (MEN1) is a dominantly inherited syndrome characterised by parathyroid hyperplasia, pancreatic neuroendocrine tumours (PNET) and pituitary adenomas, although >20 tumours are described. Clinical guidelines1 recommend annual biochemical surveillance and abdominal imaging from <10yrs and pituitary imaging every 3yrs. Age at start of surveillance is derived from the youngest reported patient with a...

Background: Recently we described a family with several members having intrauterine and postnatal growth failure as well as signs of Silver–Russell syndrome (SRS) who carried a heterozygote nonsense mutation of IGF2. The patients had low IGF-II serum levels, but normal IGF-I serum levels.Objective and hypotheses: We aimed to estimate the diagnostic value of the IGF-II, IGF-I and IGFBP-3 measurements in the assessment of children with SRS.<p clas...

Background: Copeptin is secreted in isomolar amounts along with arginine vasopressin peptide from the posterior pituitary. Its stability makes it a perfect candidate for the endocrine approach in the diagnosis of AVP deficiency. Arginine-stimulated copeptin is a possible alternative for the water deprivation test. We wondered whether basal and stimulated copeptin secretion is related to growth hormone secretion status or independent of it.<p class="abstext...

Introduction: Despite the high detection rate of GNAS molecular defects, about 30% of patients with a clinical suspect of PHP/AHO still lack a confirming molecular diagnosis. Mutations in genes encoding proteins crucial for cAMP-mediated signaling have been recently detected in a small subset of patients negative for GNAS defects, showing a phenotypic overlap between PHP and Acrodysostosis.Clinical case pres...

Background: The annual worldwide incidence of childhood adrenocortical tumors (ACT) ranges from 0.3 to 0.38/million children below the age of 15 years. Only 1–2% of them are feminizing ACT occurring in prepubertal boys and presenting with gynecomastia that normalizes after tumor removal.Case report: We present a case of a feminizing ACT. The boy was referred for bilateral gynecomastia, appeared 6 months before, at the chronological age (CA) of 7.5 y...

Background: Klippel–Feil syndrome (KFS) is characterized by congenital fusion of cervical vertebrae and has a prevalence of 1:50 000. The phenotypic expression is variable, sometimes presenting with extraskeletal symptoms.Case report: A girl was referred at the cronological age (CA) of 10.3 years with a suspected diagnosis of Turner syndrome, due to the presence of webbed neck and progressive deceleration of growth velocity. The girl, born in Russia...
