Background. Atopic dermatitis (AD) arouses high research interest these days due to its significant morbidity rate. The most crucial risk factor for its development is the intestinal microbiota composition. The correlation of this factor with the development of AD in children requires further study. Objective. The aim of the study is to perform comparative analysis of the intestinal microbiota in 1–5 years old children with AD and conditionally healthy children via 16S-sequencing of ribosomal RNA (rRNA) of bacterial genes. Methods. We have conducted cross sectional study. 60 children with diagnosed AD and 15 conditionally healthy children aged from 1 to 5 years were surveyed. Intestinal microbiota was examined via 16S-sequencing of rRNA of bacterial genes. Results. The intestinal microbiota in children with AD and conditionally healthy children has statistically significant differences. Despite the absence of significant differences in species richness of compared groups, children with AD had the elevation in the metagenome of Proteobacteria; Bacilli and Gammaproteobacteria classes; Enterococcaceae and Veillonellaceae families; Eggerthella, Dialister and Enterobacter genus; as well as the decrease in the relative value of Actinobacteria, Bacteroidetes, Verrucomicrobia; Bacteroidales and Bifidobacteriales orders; Bifidobacteriaceae, Bacteroidaceae, Erysipelotrichaceae families; Lachnoclostridium, Roseburia, Prevotella, Coprococcus, Ruminococcus, Faecalibacterium, Bifidobacterium, Bacteroides genus; decrease of Bifidobacterium longum, Faecalibacterium prausnitzii, Bacteroides fragilis. Conclusion. It was revealed that the intestinal microbiota of children with AD has significant differences in taxonomic composition with the microbiota of conditionally healthy children. Elevation of Proteobacteria, Bacilli and Gammaproteobacteria classes, Eggerthella, Dialister and Enterobacter genus can be the risk factor for this disease development, whereas decrease of such bacteria as Verrucomicrobia, Bacteroidales and Bifidobacteriales can aggravate atopic symptoms. Thus, the need for further study of intestinal microbiota in children with AD is justified to establish the correlation of these bacteria with the disease course.

Background: Due to the sensitizing constituents of eye cosmetics, allergic contact dermatitis is considered a frequent cause of eyelid dermatitis. An association between eyelid dermatitis and nickel contained in make-ups remains controversial. Objective: The study aimed to assess the association between nickel allergy, the use of pigmented makeup products and self-reported eyelid dermatitis. Method: This multi-centric, cross-sectional study enrolled 165 women sensitized to nickel (patients) and 103 women without intolerance to metals (controls). We recorded: demographics, atopy, use of pigmented eye cosmetics (mascara, eyeshadow, eyeliner, eyebrow pencil), and previous eyelid dermatitis. Among the patients, any co-sensitization to cosmetics or metals was recorded. Results: 87.3% of the patients and 91.3% of the controls reported their use of eye make-up; 44.9% and 52.4%, respectively, reported previous episodes of eyelid dermatitis, without significant differences. The occurrence of eyelid dermatitis was significantly associated with the use of eye make-up products, both in general and considering each product separately. Age, atopy, or co-sensitization to other metals or cosmetics did not affect the occurrence of eyelid dermatitis. Conclusion: Nickel allergy should not be considered the main risk factor for eyelid dermatitis. The use of pigmented eye make-up may be a triggering factor for eyelid dermatitis, probably due to an irritant action.

Background About 60% of individuals with atopic dermatitis (AD) develop their first manifestation during infancy. Cow’s milk (CM) exposure is considered to be a risk factor for AD.Objective To evaluate for an association between cow’s milk exposure and atopic dermatitis in infants > 6 months of age.  Methods This cross-sectional study consisted of subjects from a previous study and new subjects recruited in order to meet the minimum required number of subjects. Our study population comprised 120 infants, born between 1 February and 30 November, 2012 in Sanglah Hospital, Denpasar. Subjects were divided into CM and non-CM groups and analyzed for their risk of AD. Subjects were included to CM group if they were fed with cow’s milk/formula  and included to non-CM group if they were breastfeed exclusively in the first six months of life. Other possible risk factors were assessed by multivariate analysis. Results One hundred twenty subjects were enrolled and analyzed (59 in the CM and 61 in the non-CM groups). The prevalence of AD was 30%. Multiple logistic regression analysis revealed a significant association between CM exposure and AD, with odds ratio (OR) 2.37 (95%CI 1.036 to 5.420; P=0.04). In addition, maternal diet including eggs and/or cow’s milk during the breastfeeding period was significantly associated with AD in infants (OR 3.18; 95%CI 1.073 to 9.427; P=0.04).Conclusion Cow’s milk exposure is significantly associated with atopic dermatitis in infants  > six months of age.

Abstract Background Recognition of temporomandibular joint (TMJ) involvement in children with juvenile idiopathic arthritis (JIA) has gained increasing attention in the past decade. The clinical assessment of mandibular range of motion characteristics is part of the recommended variables to detect TMJ involvement in children with JIA. The aim of this study was to explore explanatory variables for mandibular range of motion outcomes in children with JIA, with and without clinically established TMJ involvement, and in healthy children. Methods This cross-sectional study included children with JIA and healthy children of age 6–18 years. Mandibular range of motion variables included active and passive maximum interincisal opening (AMIO and PMIO), protrusion, laterotrusion, dental midline shift in AMIO and in protrusion. Additionally, the TMJ screening protocol and palpation pain were assessed. Adjusted linear regression analyses of AMIO, PMIO, protrusion, and laterotrusion were performed to evaluate the explanatory factors. Two adjusted models were constructed: model 1 to compare children with JIA and healthy children, and model 2 to compare children with JIA with and without TMJ involvement. Results A total of 298 children with JIA and 169 healthy children were included. Length was an explanatory variable for the mandibular range of motion excursions. Each centimeter increase in length increased AMIO (0.14 mm), PMIO (0.14 mm), and protrusion (0.02 mm). Male gender increased AMIO by 1.35 mm. Having JIA negatively influenced AMIO (3.57 mm), PMIO (3.71 mm), and protrusion (1.03 mm) compared with healthy children, while the discrepancy between left and right laterotrusion raised 0.68 mm. Children with JIA and TMJ involvement had a 8.27 mm lower AMIO, 7.68 mm lower PMIO and 0.96 mm higher discrepancy in left and right laterotrusion compared to healthy children. Conclusion All mandibular range of motion items were restricted in children with JIA compared with healthy children. In children with JIA and TMJ involvement, AMIO, PMIO and the discrepancy between left and right laterotrusion were impaired more severely. The limitation in protrusion and laterotrusion was hardly clinically relevant. Overall, AMIO is the mandibular range of motion variable with the highest restriction (in millimeters) in children with JIA and clinically established TMJ involvement compared to healthy children.

AbstractBetween 2009 and 2013, a large cross-sectional study on the health consequences of the Chernobyl nuclear accident was performed in the contaminated and uncontaminated territories of the Bryansk Oblast (Russian Federation). The objective of this work was to confirm or refute a possible association between childhood cardiac arrhythmia and a chronic exposure to caesium-137. As part of this study, a large number of electrocardiographic and cardiac ultrasound parameters were collected from 18,152 children aged 2–18 years including 12,512 healthy ones not contaminated with caesium-137. It seemed therefore relevant for us to share in a second publication these medical data based on healthy and uncontaminated children with the scientific community because of the large quantities and the limited availability of such kind of data. In the present study, relating to electrocardiographic parameters, the measurements performed fully reflect the expected evolution of the paediatric electrocardiogram between 5 and 18 years of age. Thus, the median values were generally quite close to those available in the literature. In contrast, differences in the 2nd and 98th percentiles were notable and could be explained in particular by the type of equipment used, the number of subjects included in the study and racial disparities. As for echocardiographic parameters, the evolution of the measured values in age groups is consistent with what was expected considering factors such as growth. In comparison with other scientific studies that have investigated these echocardiographic parameters, some differences by age groups have been identified. The ethnic factor truly appears to be a relevant feature to consider. In view of the results, it appeared essential to the authors to approach the methodological conditions of the scientific studies already published on the topic to be truly comparable and thus to provide a reliable answer on a topic for which real expectations in terms of medical care are required.
