Type 1 diabetes mellitus (T1D) is one of the most demanding chronic diseases for children and their families, since controlling diabetes involves a process of co-regulation with attachment figures. However, there is insufficient evidence in middle childhood on psychological mechanisms involved that might complicate the adaptation of these children. Therefore, 106 children ( N = 31 with T1D and N = 75 as matched healthy group [HG]) aged 8 to 13 were assessed using the Child Attachment Interview, the Child Behavior Checklist, and the measure of glycated hemoglobin. Results showed that insecure T1D children did not have worse diabetes control than the secure ones. However, T1D children differed from HG for higher levels of idealization to father and withdrawn/depressed problems. Moreover, T1D children with insecure attachment to mother scored significantly higher in anxious/depressed, withdrawn/depressed, attention problems, and rule-breaking behavior, while T1D children with insecure attachment to father scored significantly higher only in the withdrawn/depressed scale compared to the remaining children. Therefore, diabetes does not in itself determine a psychological vulnerability in middle childhood, but the presence of an insecure attachment, especially to the mother, worsens the psychological adaptation of T1D children. Psychological support should be provided for these young patients and their families.

Selective IgA deficiency (SIgAD) is the most common humoral primary immunodeficiency. Long-term follow-up data in large cohort of pediatric patients are scarce. We report on a single-center cohort of 184 pediatric patients affected with selective IgA deficiency and describe the characteristics at diagnosis and during follow-up. Respiratory infections were the most common clinical finding leading to the initial diagnosis (62%). Positive family history for antibody deficiencies (selective IgA deficiency, common variable immunodeficiency) led to SIgAD diagnosis in 16% of cases. During follow-up, while the incidence of respiratory infections was not particularly high, gastrointestinal symptoms were reported in 27% of patients. Allergic manifestations were found in 23% at diagnosis and an additional 16% of patients during follow-up, leading to a prevalence of atopy of 39% among SIgAD patients. Autoimmune manifestations, excluding celiac disease, were found in 9% of affected patients during follow-up. Celiac disease was found in a high prevalence (14%). Increase of serum IgA levels to partial deficiency (9%) and normal serum levels for age (4%) was observed during follow-up. A small percentage of patients (2%) progressed to common variable immunodeficiency (CVID). In conclusion, this is the first study to describe a large single-center pediatric cohort of patients affected with SIgAD, revealing that overall most patients do well with regard to infections. Many develop CD, at a rate much higher than the general population. A few normalize their IgA levels. A few progress to CVID. Thus, careful follow-up is suggested to diagnose and treat potential complications earlier for avoiding potential morbidities.

Reflectance hyperspectral imaging provides a non-invasive tool for the diagnostics, analysis and documentation of paintings. It supplies high quality digital images with spectral information associated to each pixel of the imaged area. Working in the short-wave infrared range (1000-2500 nm) allows for the investigation of inner layers of paintings, by revealing underdrawings, hidden details, and characterizing artists' materials. The performance of spectral imaging systems is usually established in the laboratory using reference targets to measure the system spatial and spectral resolution. However, when dealing with paintings, using custom built test targets made with materials more representative of the artwork can provide a better understanding of advantages and limitations of the system. This paper looks at the benefits of hyperspectral imaging in the 900-1700 nm region as applied to the study of paintings. A test panel target, made according to early Renaissance Florentine painting techniques was used for assessing the diagnostic capability of the hyperspectral system developed at the "Nello Carrara" Institute of Applied Physics. The paper illustrates how different spatial and spectral resolutions can impact the documentation of underdrawings and identification of artists' materials. Finally, the analysis of a fifteenth-century panel painting by Fra Angelico is presented as case study.

Objective Transient neonatal diabetes mellitus (TNDM) is caused by activating mutations in ABCC8 and KCNJ11 genes (KATP/TNDM) or by chromosome 6q24 abnormalities (6q24/TNDM). We wanted to assess whether these different genetic aetiologies result in distinct clinical features. Design Retrospective analysis of the Italian data set of patients with TNDM. Methods Clinical features and treatment of 22 KATP/TNDM patients and 12 6q24/TNDM patients were compared. Results Fourteen KATP/TNDM probands had a carrier parent with abnormal glucose values, four patients with 6q24 showed macroglossia and/or umbilical hernia. Median age at diabetes onset and birth weight were lower in patients with 6q24 (1 week; −2.27 SD) than those with KATP mutations (4.0 weeks; −1.04 SD) (P = 0.009 and P = 0.007, respectively). Median time to remission was longer in KATP/TNDM than 6q24/TNDM (21.5 weeks vs 12 weeks) (P = 0.002). Two KATP/TNDM patients entered diabetes remission without pharmacological therapy. A proband with the ABCC8/L225P variant previously associated with permanent neonatal diabetes entered 7-year long remission after 1 year of sulfonylurea therapy. Seven diabetic individuals with KATP mutations were successfully treated with sulfonylurea monotherapy; four cases with relapsing 6q24/TNDM were treated with insulin, metformin or combination therapy. Conclusions If TNDM is suspected, KATP genes should be analyzed first with the exception of patients with macroglossia and/or umbilical hernia. Remission of diabetes without pharmacological therapy should not preclude genetic analysis. Early treatment with sulfonylurea may induce long-lasting remission of diabetes in patients with KATP mutations associated with PNDM. Adult patients carrying KATP/TNDM mutations respond favourably to sulfonylurea monotherapy.

Many variables influence the outcome of growth hormone (GH) therapy (GH dose and duration, height - SDS at treatment start or at puberty onset, bone age, mid parental height, growth velocity, age, etc.). Nevertheless, all these factors only partially explain the interindividual variability in response to GH in GH deficiency (GHD) and in short non-GHD subjects. To this regard, genes coding for factors involved in GH action could play an important role. GH acts through the GH receptor (GHR), and therefore the GHR gene could be the first candidate to influence the response to GH. Polymorphisms of the GHR have been described in exons 3, 6 and 10. The first one consists in the deletion (d3) or retention (fl) of the entire exon 3. The d3 polymorphism has been recently associated with a better growth response to GH in idiopathic short stature subjects and in short children born small for gestational age. Subsequent studies on the same and other categories of short children (idiopathic short stature, small for gestational age, GHD, Turner syndrome) have reported controversial results, with some confirming the role of d3 and others showing no effect. This review analyses these studies trying to explain the apparent discrepancies, mainly due to different selection criteria and different dose regimens in treating GHD and non-GHD short subjects.
