Italian translation, cultural adaptation and validation of the PedsQL™ 3.0 Diabetes Module questionnaire in children with type 1 diabetes and their parents.

Background: The PedsQL™3.0 Diabetes Module is a widely used instrument to measure the disease-specific health-related quality of life summary measures in children and adolescents with type 1 diabetes. After cultural adaptation, we confirmed reliability and validity of PedsQL™3.

Plasma homocysteine in patients with retinal vein occlusion.

Purpose: To evaluate total plasma homocysteine (HCY) during fasting and post methionine load test (MLT), serum folate, serum vitamin B12, and methylenetetrahydrofolate reductase (MTHFR) mutation in patients with retinal vein occlusion (RVO) and to examine the association between these risk factors and 2 subtypes of RVO: central (CRVO) and branch (BRVO).

Methods: This case-control study included 91 Italian patients presenting a first RVO and 71 healthy subjects, matched by age, without history of thromboembolic diseases, glaucoma, or malignancy. Homocysteine fasting and after MLT, serum folate level, serum vitamin B12 level, and other laboratory tests were assessed.

Hyperglycaemia and β-cell antibodies: is it always pre-type 1 diabetes?

We describe 10-year-old girl with mild incidental hyperglycaemia, impaired glucose tolerance and GADA positivity. Family history for mild hyperglycaemia and GADA fluctuation alerted us to a possible MODY diagnosis which was confirmed by detection of GCK mutation c.626C>T; p.

May T1 diabetes mellitus protect from asthma?

Background: Type 1 diabetes mellitus (T1DM) may be associated with allergy. It was previously reported that >20% of children with T1DM had allergic rhinitis (AR), but none was asthmatic. This finding was surprising as allergic rhinitis is frequently associated with asthma and asthma prevalence is about 10% of the general paediatric population.

Molecular cytogenetic characterization of the first reported case of an inv dup (4p)(p15.1-pter) with a concomitant 4q35.1-qter deletion and normal parents.

Inverted duplications associated with terminal deletions are complex anomalies described in an increasing of chromosome ends. We report on the cytogenetic characterization of the first de novo inv dup del(4) with partial 4p duplication and 4q deletion in a girl with clinical signs consistent with "recombinant 4 syndrome". This abnormality was suspected by banding, but high-resolution molecular cytogenetic investigations allowed us to define the breakpoints of the rearrangement.

Wolfram syndrome: new mutations, different phenotype.

Background: Wolfram Syndrome (WS) is an autosomal recessive neurodegenerative disorder characterized by Diabetes Insipidus, Diabetes Mellitus, Optic Atrophy, and Deafness identified by the acronym "DIDMOAD". The WS gene, WFS1, encodes a transmembrane protein called Wolframin, which recent evidence suggests may serve as a novel endoplasmic reticulum calcium channel in pancreatic β-cells and neurons. WS is a rare disease, with an estimated prevalence of 1/550.

Slow-release insulin in cystic fibrosis patients with glucose intolerance: a randomized clinical trial.

Background: Early stages of glucose metabolism impairment are a period at risk in the long-term prognosis of cystic fibrosis (CF). Slow-release synthetic insulin glargine can be a therapeutic tool in this metabolic condition.

Methods: In this phase 3 multicenter, controlled, two-arm, randomized clinical study, glargine was administered up to a dosage of 0.

Retinopathy screening in patients with type 1 diabetes diagnosed in young age using a non-mydriatic digital stereoscopic retinal imaging.

Background: Diabetic retinopathy seriously impairs patients' quality of life, since it represents the first cause of blindness in industrialized countries.

Aim: To estimate prevalence of retinopathy in young Type 1 diabetes patients using a non-mydriatic digital stereoscopic retinal imaging (NMDSRI), and to evaluate the impact of socio-demographic, clinical, and metabolic variables.

Subjects And Methods: In 247 young patients glycated hemoglobin (HbA1c), gender, age, pubertal stage, presence of diabetic ketoacidosis (DKA), HLA-DQ heterodimers of susceptibility for Type 1 diabetes, and β-cell autoimmunity at clinical onset were considered.

Mother and daughter carrying the same KCNJ11 mutation but with a different response to switching from insulin to sulfonylurea.

KCNJ11 gene mutations are related to permanent neonatal diabetes mellitus (PNDM). Glycemic stability minimizes the risk of complications. Sulfonylureas (SU) are the proven best therapeutic option.

A new SPINK5 mutation in a patient with Netherton syndrome: a case report.

We report on a case of Netherton syndrome showing a new SPINK5 mutation (c.957_960dupTGGT duplication in exon 11), associated with partial defect of biotinidase.

The ALBA project: an evaluation of needs, management, fears of Italian young patients with type 1 diabetes in a school setting and an evaluation of parents' and teachers' perceptions.

Objective: To determine how Italian parents and school personnel of 6-13-year-old children with type 1 diabetes (T1D) manage during school hours, including insulin administration, management of hypoglycemia, and glucagon use. A further aim was an investigation into the responsibilities and training of school personnel regarding diabetes.

Research Design And Methods: After an initial qualitative phase, semi-structured questionnaires were completed by a sample of parents and teachers.

Genetic investigation in an Italian child with an unusual association of atrial septal defect, attributable to a new familial GATA4 gene mutation, and neonatal diabetes due to pancreatic agenesis.

Aims: Permanent neonatal diabetes is a rare condition affecting 1 in 300,000-400,000 live births; only in 60% of cases it is possible to identify the genetic defect. The condition of pancreatic agenesis is rarer still. Only two genes are known to determine this phenotype: PDX-1 and PTF1A.

Serum transforming growth factor β1 during diabetes development in non-obese diabetic mice and humans.

Recent data show that regulatory cells with transforming growth factor (TGF)-β1-dependent activity are able to restore self-tolerance in overtly diabetic non-obese diabetic (NOD) mice. Thus, TGF-β1 seems to have a relevant role in protection from autoimmune diabetes. Our aim was to investigate the possible significance of serum TGF-β1 measurement in the natural history of diabetes in NOD mice, as well as in children positive for at least one islet-related antibody.
