A young child presents to their primary health provider with fever and irritability. How likely is a urinary tract infection? How should a urine sample be collected? How accurate are urinary dipsticks and microscopy compared with culture for the diagnosis? What route and type of antibiotics should be used? What imaging is indicated? Diagnosing and treating children with urinary tract infection presents many questions. This review summarises the most relevant recent primary studies, systematic reviews and guidelines. © 2010 The Authors.

Background: A chronic illness, such as Juvenile Idiopathic Arthritis (JIA), has an impact on the whole family, especially on parents caring for the ill child. Therefore the aim of this study is to evaluate parental Health Related Quality of Life (HRQOL) and parental perceptions of child vulnerability (PPCV) and associated variables in parents of a child with JIA.Methods: Parents of all JIA patients (0-18 years) in Amsterdam, the Netherlands, were eligible. HRQOL was measured using the TNO-AZL Questionnaire (TAAQOL) and PPCV using the Child Vulnerability Scale (CVS). The HRQOL of parents of a child with JIA was compared to a norm population, and differences between parents of a child with JIA and active arthritis versus parents of a child with JIA without active arthritis were analyzed (ANOVA). For PPCV, parents of a child with JIA were compared to a norm population, including healthy and chronically ill children (Chi2, Mann-Whitney U test). Variables associated with PPCV were identified by logistic regression analyses.Results: 155 parents (87.5% mothers) completed online questionnaires. JIA parents showed worse HRQOL than parents of healthy children on one out of twelve domains: fine motor HRQOL (p < .001). Parents of children with active arthritis showed worse HRQOL regarding daily activities (p < .05), cognitive functioning (p < .01) and depressive emotions (p < .05) compared to parents of children without active arthritis. Parents of children with JIA perceived their child as more vulnerable than parents of a healthy child (p < .001) and parents of a chronically ill child (p < .001). Parents of children with active arthritis reported higher levels of PPCV (p < .05) than parents of children without active arthritis. A higher degree of functional disability (p < .01) and shorter disease duration (p < .05) were associated with higher levels of PPCV.Conclusion: The HRQOL of JIA parents was comparable to the HRQOL of parents of a healthy child. JIA parents of a child with active arthritis showed worse HRQOL than parents of a child without active arthritis. Parents perceived their child with JIA as vulnerable. © 2014 Haverman et al.; licensee BioMed Central Ltd. Source

Background: Mutations in the SP110 gene result in infantile onset of the autosomal recessive primary immunodeficiency disease veno-occlusive disease with immunodeficiency syndrome (VODI), which is characterized by hypogammaglobulinemia, T-cell dysfunction, and a high frequency of hepatic veno-occlusive disease. Objectives: We sought to further characterize the clinical features, B-lineage cellular immunologic findings, and molecular pathogenesis of this disorder in 9 patients with new diagnoses, including 4 novel mutations from families of Italian, Hispanic, and Arabic ethnic origin. Methods: Methods used include clinical review; Sanger DNA sequencing of the SP110 gene; determination of transfected mutant protein function by using immunofluorescent studies in Hep-2 cells; quantitation of B-cell subsets by means of flow cytometry; assessments of B-cell function after stimulation with CD40 ligand, IL-21, or both; and differential gene expression array studies of EBV-transformed B cells. Results: We confirm the major diagnostic criteria and the clinical utility of SP110 mutation testing for the diagnosis of VODI. Analysis of 4 new alleles confirms that VODI is caused by reduced functional SP110 protein levels. Detailed B-cell immunophenotyping demonstrated that Sp110 deficiency compromises the ability of human B cells to respond to T cell-dependent stimuli and differentiate into immunoglobulin-secreting cells in vitro. Expression microarray studies have identified pathways involved in B-lymphocyte differentiation and macrophage function. Conclusion: These studies show that a range of mutations in SP110 that cause decreased SP110 protein levels and impaired late B-cell differentiation cause VODI and that the condition is not restricted to the Lebanese population. © 2012 American Academy of Allergy, Asthma & Immunology.

Epidemiological studies indicated that more than 15% of the population in western countries suffer because of severe forms of periodontitis. In this respect, the recognition of the relationship between oral and systemic health is growing, thus receiving remarkable interest in scientific literature. In fact, periodontitis may increase the risk for a group of life-threatening conditions such as atherosclerosis, stroke or low birth weight. The American Diabetes Association has reported that individuals with uncontrolled diabetes (defined as 200mg/dL of glucose on three consecutive readings) undergo an increased risk of infections, abnormal wound healing and consequent increased recovery time. Moreover, diabetics may be more likely to develop periodontal and cardiovascular disease than non diabetics, if note. History of poorly controlled chronic periodontal disease can alter diabetic/glycemic control. This may originate from a likely continuous passage of bacterial toxins and/or bacteria into the bloodstream, and/or from an exaggerated release of inflammatory mediators. This review is aimed at elucidating the connections between the status of oral health and glycemic control in diabetes. Source

This study aimed to define the profile of asthmatic children in Bahrain and the prevalence of sensitization to aeroallergens and foods. A total of 95 children who were clinically diagnosed with asthma were enrolled: 71.6% mild, 20.0% moderate and 8.4% severe asthma (NIH criteria). Serum IgE concentrations were elevated (> 200 kU/L) in 21.1% of patients and highly elevated (> 400 kU/L) in 9.5%. Absolute eosinophil counts were elevated (> 350 × 106/L) in 54.8%. Overall, 67.4% of children were atopic; 56.8% were sensitive to inhalant allergens and 39.0% to foods. The atopic profile was generally similar to asthmatic children in the region and worldwide. Conditions significantly associated with atopic asthma included food allergies, allergic rhinitis and eczema. Source
