Abstract
Background: 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.Methods: 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 Staphylococcus aureus (SA) colonization status were assessed before and following bathing.Results: Significant improvements were found in total SCORAD (p = .030), POEM (p = .004), SA colonization status (p = .002), and log-transformed IgE level (p = .009) among patients who bathed with pine-tar in the overall RCT study using intention-to-treat analysis. For per protocol analysis, significant improvements were found in total SCORAD (p = .024), objective SCORAD (p = .011), extent (p = .014), intensity (p = .032), pruritus (p = .047), POEM (p = .044), SA colonization status (p = .035), and log-transformed IgE level (p = .028). Acceptability to both bath-oils was good, and no product-related serious adverse events were recorded.Conclusions: Bathing with pine-tar is an efficacious and recommendable adjuvant practice for AD patients. Disease improvement is associated with reduction of SA and IgE.

Abstract
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.

Abstract
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.

Abstract
Introduction: Eczema is the most common childhood skin problem in Hong Kong. Treatment adherence is crucial in symptom management and the effectiveness of eczema management. The Problematic Experiences of Therapy Scale (PETS) is used to assess adherence to treatment among children with eczema. Objective: This study examined the psychometric properties of the translated Chinese version of PETS (C-PETS) among parents and caregivers of children with eczema. Methods: PETS was translated into Chinese and data obtained from a convenience sample of 147 Chinese participants from a regional hospital in Hong Kong. Results: The internal consistency of C-PETS with a Cronbach's α of 0.93 and good test-retest reliability with weighted Kappa ranging from 0.74 to 0.89 were obtained. Significant positive correlations were found among the C-PETS, Children's Dermatology Life Quality Index (r = 0.25, p = .002), and Severity Grading of Atopic Dermatitis scores (r = 0.38, p = .001). A significant negative correlation was found between C-PETS and Chinese adaptation of Generic Self-Efficacy scale (r = -0.40, p = .001). Confirmatory factor analysis showed that the data supported the structural validity of C-PETS. Conclusion: This study indicates that C-PETS is a reliable and valid measure to evaluate treatment adherence for Chinese parents and caregivers of children with eczema.

Abstract
Recent studies of muscle-invasive bladder cancer show that FGFR3 mutations are generally found in a luminal papillary tumour subtype that is characterised by better survival than other molecular subtypes. To better understand the role of FGFR3 in invasive bladder cancer, we examined the process of tumour development induced by the tobacco carcinogen OH-BBN in genetically engineered models that express mutationally activated FGFR3 S249C or FGFR3 K644E in the urothelium. Both occurrence and progression of OH-BBN-driven tumours were increased in the presence of an S249C mutation compared to wild-type control mice. Interestingly, at an early tumour initiation stage, the acute inflammatory response in OH-BBN-treated bladders was suppressed in the presence of an S249C mutation. However, at later stages of tumour progression, increased inflammation was observed in S249C tumours, long after the carcinogen administration had ceased. Early-phase neutrophil depletion using an anti-Ly6G monoclonal antibody resulted in an increased neutrophil-to-lymphocyte ratio at later stages of pathogenesis, indicative of enhanced tumour pathogenesis, which supports the hypothesis that suppression of acute inflammation could play a causative role. Statistical analyses of correlation showed that while initial bladder phenotypes in morphology and inflammation were FGFR3-dependent, increased levels of inflammation were associated with tumour progression at the later stage. This study provides a novel insight into the tumour-promoting effect of FGFR3 mutations via regulation of inflammation at the pre-tumour stage in the bladder.

Abstract
Aim To review current classes of emollients in the market, their clinical efficacy in atopic dermatitis (AD) and considerations for choice of an emollient. Methods PubMed Clinical Queries under Clinical Study Categories (with Category limited to Therapy and Scope limited to Narrow) and Systematic Reviews were used as the search engine. Keywords of ‘emollient or moisturizer’ and ‘atopic dermatitis’ were used. Overview of findings Using the keywords of ‘emollient’ and ‘atopic dermatitis’, there were 105 and 36 hits under Clinical Study Categories (with Category limited to Therapy and Scope limited to Narrow) and Systematic Reviews, respectively. Plant-derived products, animal products and special ingredients were discussed. Selected proprietary products were tabulated. Conclusions A number of proprietary emollients have undergone trials with clinical data available on PubMed-indexed journals. Most moisturizers showed some beneficial effects, but there was generally no evidence that one moisturizer is superior to another. Choosing an appropriate emollient for AD patients would improve acceptability and adherence for emollient treatment. Physician’s recommendation is the primary consideration for patients when selecting a moisturizer/emollient; therefore, doctors should provide evidence-based information about these emollients.

Abstract
BACKGROUND Atopic eczema is a common childhood disease associated with high IgE and eosinophilia. We characterized the clinical features associated with hyper-IgE (defined as IgE > 2000 IU/L) in eczema. METHODS Nottingham Eczema Severity Score (NESS), family and personal history of atopy, skin prick test (SPT) for common food and aeroallergens, highest serum IgE ever and eosinophil counts were evaluated in 330 children eczema patients. Childhood-NESS (NESS performed at <10 years of age) and adolescent-NESS (NESS performed at >10 years of age) were further analyzed. RESULTS IgE correlated with NESS (spearman coefficient 0.35, p < 0.001) and eosinophil percentage (spearman coefficient 0.56, p = 0.001). Compared with IgE ≤ 2000IU/L (n = 167), patients with hyper-IgE (n = 163) were associated with male gender (p = 0.002); paternal atopy (p = 0.026); personal history of atopic rhinitis (p = 0.016); asthma (p < 0.001); dietary avoidance (p < 0.001); use of wet wrap (p < 0.001); traditional Chinese medicine use (TCM, p < 0.001); immunomodulant use (azathioprine or cyclosporine, p < 0.001); skin prick sensitization by dust mites (p < 0.001), cats (p = 0.012), dogs (p = 0.018), food (p = 0.002); eosinophilia (p < 0.001); more severe disease during childhood (p < 0.0001) and during adolescence (p < 0.0001), but not onset age of eczema or maternal atopy. Logistic regression showed that hyper-IgE was associated with personal history of asthma (exp(B) = 5.12, p = 0.002) and eczema severity during childhood and adolescence (p < 0.001). For patients <10 years of age, dust mite sensitization (p = 0.008) was associated with hyper-IgE. For patients >10years of age, food allergen sensitization was associated with hyper-IgE (p = 0.008). CONCLUSIONS Hyper-IgE is independently associated with asthma, more severe atopy and more severe eczema during childhood and adolescence. IgE > 2000 IU/L may be a tool to aid prognostication of this chronic relapsing dermatologic disease and its progression to asthma.
