Association between osteocalcin and residual ß-cell function in children and adolescents newly diagnosed with type 1 diabetes: a pivotal study.

PURPOSE: This pivotal study aimed to evaluate circulating levels of bone remodeling markers in children and adolescents at the onset of type 1 diabetes (T1D). Additionally, we assessed their correlation with glucose control, residual ß-cell function, and the severity of presentation. METHODS: In this single-center cross-sectional study, we recruited children and adolescents newly diagnosed with T1D at our tertiary-care Diabetes Centre. Anamnestic, anthropometric, clinical, and biochemical data at T1D diagnosis were collected. Basal and stimulated C-peptide levels were assessed, along with the following bone remodeling biomarkers: osteocalcin (OC), alkaline phosphatase (ALP), parathormone (PTH), 25-OH Vitamin D (25OH-D), and the C-terminal cross-linked telopeptide of type 1 collagen (CTX). RESULTS: We enrolled 29 individuals newly diagnosed with T1D, with a slight male prevalence (51.7%). The mean age was 8.4 ± 3.7 years. A positive correlation between OC and stimulated C-peptide (R = 0.538; p = 0.026) and between PTH and serum HCO3- (R = 0.544; p = 0.025) was found. No other correlations between bone remodeling biomarkers and clinical variables were detected. CONCLUSION: Our data showed a positive correlation between OC levels and residual ß-cell function in children and adolescents at T1D presentation. Further longitudinal studies evaluating OC levels in pediatric subjects with T1D are needed to better understand the complex interaction between bone and glucose metabolisms.

Vitulia questionnaire: a new instrument to evaluate quality of life in children aged 4-7 years with food allergy.

Summary: Background. Food allergy (FA) negatively affects health-related quality of life (HR-QoL) of children and caregivers. To date, no questionnaire self-compiling assessing the HR-QoL in pre-school children with FA is available. The aim of this study is to develop and validate a self-administered, rapid and easy questionnaire to evaluate the HR-QoL in children ≥ 7 years with IgE-mediated FA. Methods. A two-center prospective study was conducted including children aged 4-7 years with IgE-mediated FA. The Vitulia questionnaire was administered to study participants at the baseline (T0) and after one month (T1). To assess the feasibility and reliability, the Vitulia questionnaire was compared with other two pre-existing questionnaires: FAQLQ-PF and the KiddyKindl, which were also tested at both T0 and T1. The validation phase aimed to assess the following psychometric properties: convergent validity, internal consistency, discriminant validity and sensitivity to change. Results. One hundred patients (62% male, mean age 5.4 ± 1.2 years) were enrolled. The Vitulia questionnaire showed a good internal consistency along with an excellent reliability and repeatability of the measure. Another noteworthy feature of the questionnaire was its discriminant validity as demonstrated by the ability to provide different scores in subgroups, which have differences in terms of quality of life. On the other hand, the questionnaire seems not be sensitive to changes in health status over time. Conclusions. The Vitulia questionnaire represents a valid tool, quick and easy to interpret, which can be used to assess the quality of life in preschool children with IgE-mediated FA.

Renal anomalies in newborns with vacterel association: case series and literature review.

Nocturnal enuresis (NE) was defined by the World Health Organization (ICD-10) and the American Psychiatric Association (DSM-5) as bed-wetting in children aged >5 years. In cases of mental retardation, the developmental age may be equivalent to 5 years. In this review, we focus on the current knowledge about the etiology of enuresis and the most recent therapeutical options. Both non-pharmacological and pharmacological therapies are included, although the relative effectiveness of each remains uncertain. To date, motivational, alarm and drug therapies are the mainstay of treatment. Alarm therapy remains the first-line treatment modality for NE, while desmopressin is the most commonly used medical treatment.

Does chlordesmethyldiazepam have a specific anti-erotic effect? Report on five observations.

Five observations in adult subjects (4 female, 1 male) in which the administration of chlordesmethyldiazepam (2-4 mg/day) alone, or in association with other psychodrugs has demonstrated a specific anti-erotic action, with a short therapeutic latency period, reversible, and not found in other benzodiazepines (chlordiazepoxide, diazepam, lorazepam, flunitrazepam, prazepam) which the patients had previously taken, are presented in detail. One of the cases was diagnosed with Clérambault Syndrome of seven years' duration [Acta psychiat. belg., 82, 555-564 (1982)].
