Background: Anxiety from accidental exposure and vigilant dietary monitoring impair the quality of life (QoL) of food-allergic patients. A comprehensive food allergy-specific questionnaire allows patients to accurately report their QoL. This study validated the Food Allergy Quality of Life Questionnaire (FAQLQ) series and assessed the QoL of Chinese food-allergic patients and their caregivers.Methods: FAQLQ series developed by EuroPrevall consists of four separate questionnaires for parents, children, adolescents and adults. All questionnaires were translated into traditional Chinese by standard forward and backward methods. A cross-sectional study was conducted on food-allergic patients and children's parents using an age-appropriate questionnaire. The performance indices of FAQLQ and their correlation with independent measures of food allergy were analyzed, and factor analysis was performed to confirm the factor structure of FAQLQ questionnaires.Results: Cross-sectional validation was performed on 214 participants, with 40 reassessed for test–retest reliability. Overall scores for the FAQLQ series had good internal consistency with Cronbach's α ≥.90. Good construct validity was demonstrated by correlations between FAQLQ-Parent Form, FAQLQ-Child Form, FAQLQ-Teenager Form, FAQLQ-Adult Form and Food Allergy Independent Measure (FAIM) scores, except in 0- to 3-year-old children. Test–retest analyses revealed a significant correlation between total FAQLQ score, parent-reported FAIM and food anxiety domain in 4–6 years, and between total score and FAIM in 7–12 years. Exploratory factor analysis categorized items in the FAQLQ series into three to four domains.Conclusion: FAQLQ series provide a valid and reliable measure for QoL in Chinese food-allergic patients and caregivers, except for parents of children aged 0–3 years. Items for all FAQLQ questionnaires are categorized into different functional domains in our population.

BACKGROUND Eczema is the most common childhood skin problem worldwide. Education that enhances parental self-efficacy in carrying out appropriate eczema management is crucial to controlling eczema symptoms of their children. However, the lack of such a structured education program hinders everyday lives of eczematous children and their families. This study evaluated the effects of a self-efficacy theory-based parental eczema education program in controlling eczema of Chinese children at three months after commencement of intervention. METHODS An assessor-blind, 2-arm, randomized controlled trial was conducted at an outpatient clinic of a regional hospital. One hundred and thirty-six Chinese children aged 3 months to 12 years with physician-diagnosed eczema, and their parents were recruited. The intervention was underpinned by the Social Cognitive Theory. Children's disease severity, parental self-efficacy, treatment adherence, and quality of life of family members were assessed by validated tools. Generalized estimating equation model was employed to compare differential change in each outcome across time between different groups. RESULTS Eczema severity of children and parental self-efficacy in the intervention group were found to show greater improvement at 3-month follow-up with regression coefficient (β) -16.98 (95% CI, -21.04 to -12.92; P

BACKGROUND Childhood atopic dermatitis (AD) is a chronic inflammatory disease associated with pruritus and sleep loss. It is important to evaluate quality-of-life (QoL) impairment objectively in atopic diseases in children. OBJECTIVES To investigate the utility of the Pediatric Allergic Disease Quality of Life Questionnaire (PADQLQ) in children with eczema. METHODS PADQLQ, Patient-Oriented Eczema Measure (POEM, a short-term subjective symptom score), Nottingham Eczema Severity Score (NESS, a long-term subjective symptom score) and Children's Dermatology Life Quality Index (CDLQI, a short-term subjective symptom score) were compared and correlations evaluated. RESULTS PADQLQ, POEM, NESS and CDLQI correlated well with each other (n = 132 sets; Spearman correlations: rho = 0·48-0·70, P < 0·001). A Bland-Altman plot showed a reasonably good agreement between CDLQI and PADQLQ. PADQLQ showed that symptoms of asthma, allergic conjunctivitis and allergic rhinitis were present in 20-30%, 45-71% and 58-67% of children with AD, respectively. Nevertheless, there was no association of eczema symptomatology by POEM or NESS with the severity of other allergic diseases. CONCLUSIONS PADQLQ correlates well with AD-specific severity and QoL scores and reflects all allergic symptoms that holistically influence QoL in children with AD. PADQLQ is hence a composite severity score in terms of clinical symptomatology and QoL impairment for AD.

Atopic dermatitis (AD) is a chronic inflammatory disease associated with pruritus and sleep loss. Pine-tar has long been used for various chronic skin conditions in which its polycyclic aromatic hydrocarbon (PAH) component is anti-inflammatory and its resin acids antiseptic. The null hypothesis of this trial is that there is no difference in clinical efficacy between a pine-tar product and its vehicle for AD.A 3-month, investigator-blinded, crossover, randomized control trial (RCT) was conducted in which each patient was assigned to bathing with pine-tar bath oil for one month and vehicle bath oil for another, with a washout period of 1-month in-between. Acceptability and efficacy of the bath products were measured. Disease severity scores (scoring atopic dermatitis (SCORAD) and patient-oriented eczema measure (POEM), quality of life questionnaires, noninvasive skin biophysiological measurements, blood IgE levels, and SSignificant improvements were found in total SCORAD (Bathing with pine-tar is an efficacious and recommendable adjuvant practice for AD patients. Disease improvement is associated with reduction of SA and IgE.

PURPOSE Skin hydration (SH) and transepidermal water loss (TEWL) are important skin biophysical parameters for assessment of childhood eczema. This study investigated whether age, sex, and disease status influence these parameters. METHODS Skin hydration and TEWL were measured by Delfin MoistureMeterSC and Delfin Vapometer SWL5, respectively, among children aged ≤18 years with and without eczema. Disease status was evaluated using Scoring Atopic Dermatitis (SCORAD) and Nottingham Eczema Severity Score (NESS) clinical tools. RESULTS Clinical scores and objective measurements were reviewed for 132 patients with eczema and 120 patients without eczema. In both sexes, SH was significantly higher among children aged ≤2 years with and without eczema than among children aged >2 years with and without eczema. Among children aged >2 years, SH was higher among girls with and without eczema than among boys with and without eczema. Regardless of age or sex, SH was lower among children with eczema than among children without eczema. Age-, sex-, and disease-related differences were not observed for TEWL. Skin hydration was negatively correlated with objective SCORAD (r=-0.418, P

Background: Parental self-efficacy has been found to be a critical determinant of the efficacy of interventions intended to enhance the parental management of childhood eczema. Objectives: The psychometric properties of a translated Chinese version of the Parental Self-Efficacy with Eczema Care Index (C-PASECI) were examined. Methods: The PASECI was translated in a 2-stage process involving both forward and backward translation. Subsequently, the psychometric properties of the C-PASECI were examined in a cohort of 147 Chinese parents or caregivers of children with eczema. Specifically, the internal consistency, 2-day test-retest reliability and construct validity were assessed. Results: The C-PASECI received a Cronbach’s αof 0.97, and the intraclass correlation coefficients of each item ranged from 0.93 to 0.99. Negative correlations were observed among the C-PASECI, Children’s Dermatology Life Quality Index and Scoring Atopic Dermatitis Scale scores, indicating the acceptable convergent validity of the C-PASECI. The moderate correlation observed between the C-PASECI and General Self-Efficacy Scale (Pearson’s r = 0.53, p < 0.001) reflected the acceptable concurrent validity of the C-PASECI. The results of confirmatory factor analysis supported the factorial validity of the C-PASECI. Conclusion: The C-PASECI appears to be a reliable and valid measure of parental self-efficacy in Chinese parents or caregivers of children with eczema.

BACKGROUND Allergic rhinoconjunctivitis (ARC) is a prevalent allergic condition in the pediatric population. Microbial dysbiosis has increasingly been recognized to influence on host immunity and allergic diseases. However, the microbial profile of ARC has not been characterized. This cross-sectional study aims to evaluate the changes in nasal and ocular surface microbiome of children with ARC. METHODS Ocular and nasopharyngeal swabs were collected from controls and pediatric ARC cases for 16S rRNA amplicon sequencing. The bacterial community profile was analyzed. The correlation of the microbial diversity with the ARC-related clinical scores was studied. RESULTS A total of 23 patients with ARC and 17 healthy controls were recruited;30 were ocular samples (15 controls vs 15 ARC), while 40 were nasal samples (17controls vs 23 ARC) The alpha diversity of nasopharyngeal microbiome was significantly higher in ARC patients than healthy controls (P

Background Eczema is the most common skin problem among children in Hong Kong. Previous studies have highlighted that the quality of life of the families of children with eczema influences the effects of eczema interventions. However, the Chinese version of the Family Dermatology Life Quality Index (C-FDLQI), a tool for measuring the quality of life of the families of children with eczema, has not yet been validated. Objective This study examined the psychometric properties of the C-FDLQI among parents and caregivers of children with eczema in Hong Kong. Methods This study evaluated the internal consistency, test-retest reliability and structural validity of the C-FDLQI and its convergent validity by examining its correlations with the SCORing Atopic Dermatitis (SCORAD) and the Cantonese version of the Children's Dermatology Life Quality Index (C-CDLQI) among 147 Chinese parents/caregivers of children with varying degrees of eczema. Results Based on the ratings by an expert panel, both the content validity index and semantic equivalence of the C-FDLQI were satisfactory (>0.90). The C-FDLQI showed high internal consistency, with a Cronbach α of 0.95. Its test-retest reliability was good, with weighted kappa values for the items ranging from 0.70 to 1.00. The total scores of the C-FDLQI showed positive correlations with those of the C-CDLQI (Pearson r = 0.75, p < 0.001) and SCORAD (Pearson r = 0.62, p < 0.001). Known-group comparisons of the C-FDLQI between the parents/caregivers of children with mild eczema and those of children with moderate to severe eczema showed a significant difference (t = -7.343, p < 0.001), indicating that the C-FDLQI had acceptable convergent validity. Confirmatory factor analysis supported the one-factor structure of the C-FDLQI. Conclusion The results suggest that the C-FDLQI is a reliable and valid tool for evaluating the quality of life of parents or caregivers of children with eczema in Hong Kong.

It is important to objectively measure the severity of atopic dermatitis (AD). This study aims to investigate correlations among various clinical severity scores and determine how a severity score based on symptoms alone performs.A Chinese-translated symptom score based on Patient-Oriented Eczema Measure (POEM, a short-term subjective-symptom score), Scoring Atopic Dermatitis (SCORAD, a short-term subjective-symptom and objective-sign score), Nottingham Eczema Severity Score (NESS, a long-term subjective symptoms + objective signs), Children Dermatology Life Quality Index (CDLQI, a short-term subjective-symptom score), skin hydration (SH) and transepidermal water loss (TEWL) were compared and Spearman's rho correlations was evaluated.126 sets of clinical scores from eczema patients (mean age: 11.4 ± 5.6 years; 34.7% male) were evaluated. The modified-POEM, objective SCORAD, NESS and CDLQI correlated well with each other. All round, best correlations were obtained with POEM: Objective SCORAD (rho = 0.7, p 0.001), NESS (rho = 0.69, p 0.001), SCORAD symptom of itch (rho = 0.75, p 0.01), SCORAD symptom of sleep loss (rho = 0.64, p 0.01), CDLQI (rho = 0.77, p 0.001) and SH (rho= -0.043, p 0.05). Linear stepwise-backward regression demonstrated that POEM was independently associated with CDLQI parameters of pruritus (B: 2.16; p = 0.018), activities (B: 1.80; p = 0.009), sleep disturbance (B: 2.78; p 0.001) and NESS parameter of sleep disturbance (B: 1.02; p = 0.003).Clinical scores for acute, chronic, subjective symptoms and objective signs correlated well with each other. The symptom measures by modified POEM is easy to perform by parents or patients and correlated better with most other clinical scores, making it an all-round ideal symptom-based severity score for research.
