Background: Mucolipidoses II/III (ML) are rare autosomal recessive lysosomal storage disorders (incidence: 1/325 000 live births). They have overlapping clinical phenotypes with mucopolysaccharidosis disorders and include growth retardation, facial dysmorphism, skeletal abnormalities, respiratory and heart diseases, hepatosplenomegaly and abdominal hernias. There is no specific treatment and the management has been limited to supportive care.Case present...

Background: More than two thirds of teenagers with childhood-onset GH deficiency (CO-GHD) documented normal GH response when retested at final height.Objective and hypotheses: To identify potential predictors for persistent GHD after reaching final height under rhGH with a particular accent on children with isolated GHD (IGHD).Method: Prospective study: reevaluation CO-GHD in the transition period; cohort of 27 CO-GHD patient who r...

Objective: to assess olfactory bulbs sizes and define the most common molecular defects in adolescents with congenital isolated hypogonadotropic hypogonadism.Materials and Methods: Single-centre comparative study. 36 patients were included. The main group consisted of 21 patients with mean age of 15.9 years (17 boys, 4 girls) with congenital isolated hypogonadotropic hypogonadism (IHH): 13 patients with Kallmann syndrome...

Preterm and low birth weight(LBW) newborns are at risk of thyroid dysfunction during a critical period for neurodevelpment and this dysfunction can be missed in congenital hypothyroidism screening program(CHSP). Consequently, reassessment of thyroid function has been promoted in neonatal units, added to CHSP.Objectives: To evaluate prevalence and risk factors of thyroid dysfunction in≤32weeksGA and/or 1500g newborn, and compare differ...

Background: Administration of recombinant GH (rhGH) to GH-deficient children has yielded conflicting results concerning its impact on thyroid function. Data about patients developing subclinical hypothyroidism are scanty, but it is thought to be associated with impairment of metabolic profile and lower growth response.Objective: To investigate the frequency of SH in children with pituitary dwarfism treated with rhGH, as well as its influence on rhGH ther...

Vitamin D dependent rickets type 1A (VDDR-IA) is inherited in an autosomal recessive pattern and caused by mutations in CYP27B1 gene encoding enzyme 1α-hydroxylase. Deficiency of 1α-hydroxylase leads to decrease of 1,25(OH)2 vitamin D production. VDDR-IA usually manifests clinically during the 1st year of life. Clinical features of VDDR- IA include progressive growth retardation, hypotonia, rachitic skeletal deformities, hypocalcemic seizures in early infancy. Serum ...

Background: Small for gestational age (SGA) birth size has been associated with various metabolic, hormonal and reproductive problems in later life.Objective and hypotheses: We aimed to compare differences in sex hormones, uterine and ovarian sizes in SGA and appropriate for gestational age (AGA) adolescent girls.Method: 23 SGA and 47 AGA pubertal 11–14 years old girls (median age 13.2±1.94 years, median pubertal stage 4&...

SHOX gene haploinsufficiency is a well-documented cause of short stature and skeletal abnormalities; SHOX duplications appear very rare and of uncertain clinical significance. If relatively extended, they can result in SHOX overexpression with normal or tall stature. Partial SHOX duplications seems to have a more deleterious effect on skeletal dysplasia and short stature than complete SHOX duplications. MLPA (Multiplex Ligation-dependent Probe Amplification) analysis of SHOX/P...

Background: The decreased immune tolerance caused by mutations of the autoimmune regulatory gene (AIRE) lead to a spectrum of variable organ specific autoimmune disorders known as autoimmune polyglandular syndrome type 1 (APS-1). The rarity of the syndrome and the heterogenous clinical manifestations at the onset of the disease may delay the diagnosis. Only when two major components of the triad chronic mucocutaneous candidiasis – hypoparathyroidism &nda...

Septo-optic dysplasia (SOD) is a rare congenital disorder characterized by a classic triad of optic nerve hypoplasia, agenesis of septum pellucidum and corpus callosum, and hypoplasia of the hypothalamic-pituitary axis. Up to date, a shared consensus is not available and the diagnosis relies mainly on clinical and neuroradiological findings. Even though few genes have been described as responsible for this syndrome, the precise causes of SOD remain unknown and a combination of...
