Functional analysis of a novel mutation of IGF1R gene in two twins with growth failure. An example of genotype-phenotype heterogeneity.

Deodati Annalisa , Fausti Francesca , Pampanini Valentina , Cianfarani Stefano

Background: IGF1 receptor (IGF1R) mutations are associated with pre- and post-natal growth retardation. We describe two monozygotic twins, one of them born small for gestational age (SGA), referred at the age 4 years and 2 months for short stature.Case presentation: The twins were born from non-consanguineous parents at 37-weeks gestational age by caesarean delivery. At birth: patient 1 had weight 2.076 kg (−2.4 SD...

Acrodysostosis: a case report

Pitea Marco , Crocè Ludovica , Sala Elisa , Lanzafame Ruggero , Mora Stefano

A 2.6-year-old girl of Egyptian origins comes to our attention due to a deflection of the growth rate. The girl was born small for gestational age (SGA), and is affected by congenital hypothyroidism, with normal sized thyroid, treated with Levothyroxine. At the age of 1.8, due to right lameness, an x-ray of pelvis and lower limbs was performed, as indicated by the orthopaedic. The examination showed absence of the distal tibial ossification nucleus in the right leg and entangl...

Craniosynostosis in hypophosphatasia

Pitea Marco , Sala Elisa , Ruggero Lanzafame , Crocè Ludovica , Mora Stefano

Hypophosphatasia (HPP) is a rare genetic disease caused by mutations with loss of function in the ALPL gene, which encodes for non-specific tissue alkaline phosphatase (TNSALP). We report a case of infantile hypophosphatasia. Due to positive family history for hypophosphatasia, a chorionic villus sampling was made, with evidence in composed heterozygous of variants c.407G>A and c.1489T>C in the ALPL gene. At birth the patient did not have clinical complications, however ...

A novel mutation of leptin gene in two siblings with early onset obesity

Deodati Annalisa , amodeo mariaelisa , mirra giulia , pampanini valentina , cianfarani stefano

Background: Congenital leptin deficiency is a rare cause of early-onset severe obesity. Clinical features of congenital leptin deficiency include early-onset severe obesity, marked hyperphagia, endocrine and metabolic alterations. Some patients have immune dysregulation.Case report: We describe two siblings from Libya referred for severe obesity. A boy (patient 1) referred at the age of 4 years and 3 months and a girl (p...

Prevalence of brain alterations in boys with isolated central precocious puberty

Amodeo Mariaelisa , Deodati Annalisa , Pedicelli Stefania , Pampanini Valentina , Cianfarani Stefano

Introduction: Brain magnetic resonance imaging (MRI) is routinely performed to identify brain lesions in boys with central precocious puberty (CPP). In contrast to girls, in whom more than 90% of cases are idiopathic, it has been reported that 4 up to 75% of boys with CPP have pathological brain lesions.Aim: to evaluate the prevalence of brain lesions in males with isolated CPP and to identify potential clinical and bioc...

COX deficiency: undescribed endocrinological features in three patients with SCO1 mutation

Barbato Alessandro , Gori Giulia , Sacchini Michele , Pochiero Francesca , Stagi Stefano

Background: Cytochrome C oxidase (COX) is the fourth component of the respiratory chain. This protein is located within the internal membrane of mitochondria. COX deficiency is an inherited mitochondrial disease associated with considerable genetic and clinical variability(1). In fact, four clinical subtypes of this condition have been identified, each one with several phenotypic and genetic variants. Mitochondrial complex IV deficiency nuclear type 4 is a rar...

Evaluation of body composition and microcirculation in children and adolescents with growth hormone deficiency: effects of replacement therapy.

Rosa Stefano , Ferruzzi Alessandro , Zoller Thomas , Antoniazzi Franco , Pietrobelli Angelo

Aims: The aim of the study is to evaluate body composition and microcirculation in children and adolescents with growth hormone deficiency (GHD) and the effects of replacement therapy. These parameters were also evaluated in children and adolescents with suspected GH deficiency but in whom drug stimulus testing was later found to be normal.Materials and Methods: We examined 44 patients (25 males and 19 females) aged betw...

Background: Vernal keratoconjunctivitis (VKC) patients have an elevated incidence of growth hormone deficiency and thyroid diseases. Nevertheless, no auxological data are available in these subjects.Objective and hypotheses: The purpose of this study was to evaluate the auxological features in a cohort of patients with VKC.Method: This study included 179 Caucasian VKC patients (119 males, 60 females; mean age 9.63±2.98 years) ...

New onset diabetes – frequency of DKA and positive islet autoantibodies at Varna’s diabetes center

Bazdarska Yuliya , Stefanov Hari , Bocheva Yana , Iotova Violeta

Background and Aims: Initial presentation of type 1 diabetes (T1D) is associated with different level of diabetic ketoacidosis (DKA). Four pancreatic islet cell autoantibodies (Abs) mostly associate with T1D - glutamic acid decarboxylase antibodies (anti-GAD65), tyrosine phosphatase antibodies (IA 2-Ab), insulin autoantibody (anti-IAA) and zinc transporter 8 antibodyAim: To evaluate the prevalence of DKA, the frequency o...

Pain as an onset symptom in hereditary hypophosphatemic rickets with hypercalciuria, a case report.

Sala Elisa , Pitea Marco , Lanzafame Ruggero , Mora Stefano , Vezzoli Giuseppe , Barera Graziano

We report a case of hereditary hypophosphatemic rickets with hypercalciuria (Hereditary Hypophosphatemic Rickets with Hypercalciuria, HHRH) in a 13-year-old boy, referred for evaluation due to the onset of bilateral knee pain for about two years. Pain was intermittent and walking limiting and negatively affected quality of life. Negative family history of bone/joint pathologies and kidney stones. The parents are consanguineous (first cousins), have normal stature and no histor...
