Analysis of a large panel of genes in a cohort of patients with severe short stature: detection rate and genotype-phenotype correlations

Guazzarotti Laura , Mozzato Chiara , Meneghin Alice , Nicolucci Antonio , Cassina Matteo

Short stature is a frequent reason for referral to pediatric endocrinologists and this phenotype has been associated with a large number of gene variations during the last decades, highlighting its complex and heterogeneous etiology. We evaluated the detection rate of the analysis of a selected gene panel in a cohort of patients with short stature defined as height below -2 standard deviations (SD). Overall, 134 patients were included in the study: 73 with GH deficiency (GHD),...

Monogenic Diabetes (MODY) in Adolescents and Personalized Treatment.

Mozzato Chiara , Meneghin Alice , Monti Elena , Trevisson Eva , Guazzarotti Laura

Pathologically elevated serum levels of fibroblast growth factor-23 (FGF23), a bone-secreted hormone that regulates phosphorus homeostasis, result in renal phosphate wasting leading to rickets or osteomalacia. Patterns leading to FGF23 excess are still unknown. Recently, FGF23 elevated rickets has been associated with epidermal nevus syndrome, designating the cutaneous skeletal hypophosphatemia syndrome (CSHS). The clinical picture is not completely defined as, to date, only a...

HIgh variability of phenotypic expression of the same genotype in X linked hypophosphatemic rickets (XLH)

Meneghin Alice , Mozzato Chiara , Monti Elena , Guazzarotti Laura

X-linked hypophosphataemia (XLH) is a dominant disorder caused by mutations in PHEX (located at Xp22.1), associated with rickets, lower limb deformities, pain, poor mineralization of the teeth and disproportionate short stature in children. The characteristics and severity of XLH vary between patients. Early diagnosis and specific treatment is usually decisive to improve short and long term patient outcomes. We describe the variability of phenotype in two sisters carrying the ...

Diabetic Capilaropathy: A Case Report

Andres Carlos , Tabuenca Laura , Sanchez Idoia , Diaz Laura , Chueca Maria J , Berrade Sara , Dura Teodoro , Compains Esther

Uncontrolled diabetes mellitus is a disease with a wide range of systemic complications. Eye complications may seriously threaten quality of life. Diabetic retinopathy is the most frequent diabetic ocular complication. However, diabetic capilaropathy is a little known condition of diabetic retinopathy. It is an acute optic disc edema and/or macular edema; due to an acute hyperglycaemia.Method: We present a case of a diabetic 14-years-old female with diab...

Neonatal Screening Program for Central Congenital Hypothyroidism

Braslavsky Debora , Prieto Laura , Keselman Ana , de Papendieck Laura Gruneiro , Enacan Rosa , Mendez Virginia , Bergada Ignacio , Chiesa Ana

Background: Congenital hypothyroidism (CH) comprises a heterogeneous group of disorders that includes diseases of the hypothalamo-hypophyseal system. The latter are missed on TSH based screening programs leading to increased morbidity and mortality. Additional T4 determinations, allows an early detection of CH of central origin (CH-C).Objective and hypotheses: To report the findings of a neonatal screening program based on determination of TSH...

Auxological Parameters, Endocrine Growth Factors and Insulin Resistance from Birth to 12 Months of Life in Children Born Small for Gestational Age

Guazzarotti Laura , Mauri Silvia , Occhipinti Federica , Petruzzi Mariangela , Sonnino Micol , Tenconi Andrea Angela , Pogliani Laura , Zuccotti Gian Vincenzo

Background: At present, literature regarding postnatal growth in small for gestational age (SGA) subjects and its’ correlation with growth factor levels is still controversial. A relation between IGF1 and IGFBP3 levels at birth and weight and length catch up growth has been demonstrated. In the first months of life a rapid weight catch-up growth has also been associated to an increase of leptin, basal insulin and insulin resistance.Objective and hyp...

Management of Prepubertal Gynecomastia in Two Patients with Peutz-Jeghers Sydrome: Use of Aromatase Inhibitors

Guazzarotti Laura , Mauri Silvia , Occhipinti Federica , Petruzzi Mariangela , Sonnino Micol , Tenconi Andrea Angela , Pogliani Laura , Zuccotti Gian Vincenzo

Background: Peutz-Jeghers syndrome (PJS) is a rare autosomal-dominant disorder frequently caused by the serine-threonine-kinase-11(STK11) gene mutation and characterized by hamartomatous polyps throughout the gastrointestinal tract, mucocutaneous hyperpigmentation and predisposition to several malignancies. Rarely, PJS may be associated to an oestrogen producing large cell calcifying Sertoli cell tumour that may result in gynecomastia and increased growth velocity (GV).<p ...

Gene Chimeras Involving CYP21A2 and TNXB Genes in Spanish Patients with Congenital Adrenal Hyperplasia (CAH)

Martínez Figueras Laura , Escribano Muñoz Arancha , Carcavilla Atilano , Berthold Laura , Llorente Martín Elena , Arriba Domènech María , Ezquieta Zubicaray Begoña

Background-Aim: Gene rearrangements between CYP21A2, TNXB and their homologous pseudogenes (CYP21A1P,TNXA) result in chimeric genes, responsible for the CAHX syndrome. CAHX patients show CAH and Ehlers-Danlos syndrome (EDS) symptoms. Three CAHX chimeras with different clinical severity are described: CH1 (including 120bp deletion in exon 35), CH2 and CH3. The small size and few series reported so far warrant further studies ...

Very Early Onset of Autoimmune Thyroiditis in a Toddler with Multi-organ Involvement

Marzuillo Pierluigi , Grandone Anna , Di Sessa Anna , Sanso Claudia , De Nitto Elena , Ruggiero Laura , Capristo Carlo , del Giudice Emanuele Miraglia , Perrone Laura

Background: In infants under 3 years of age acquired primary hypothyroidism caused by autoimmune thyroiditis is very rare. Hypothyroidism can manifest with different signs and symptoms and has a wide range of presentations from subclinical hypothyroidism to overt form.Objective and hypotheses: We describe a child with an unusual hypothyroidism presentation characterized by multi-organ involvement and related to acquired autoimmune thyroiditis during a ve...

Objective: Postprandial hyperinsulinaemic hypoglycaemia (PPHH) or “late dumping syndrome” is a well-recognised complication following gastrointestinal surgery and has been less commonly identified idiopathically in paediatric patients. This study describes and compares the characteristics, diagnosis, management and outcomes of paediatric idiopathic and surgical PPHH.Design: Retrospective chart review of child...
