Comorbid asthma is associated with rhinitis severity in children exposed to air pollutants.

BACKGROUND: The impact of asthma on the severity of rhinitis when children with allergic rhinitis (AR) are exposed to air pollutants has not been studied. METHODS: Children with AR (65 with asthma, 208 without asthma), aged 6-13 years, were recruited from a hospital in Taichung, Taiwan, between 2007 and 2011. Correlations between Pediatric-Rhinoconjunctivitis-Quality-of-Life score, nasal peak expiratory flow, and air pollutants were compared. With the same age, research time, and form the same city, children with AR (660 with asthma, 3174 without asthma) were selected from a database. Correlations between clinical visit times for AR and air pollutants were compared. RESULTS: In male children with AR and asthma, both clinical and database studies revealed a correlation between higher rhinitis discomfort (quality-of-life score), higher visit times for AR, and higher PM10, PM2.5, NO2, NMHC concentrations. Correlations between higher nasal inflammation/obstruction (lower expiratory flow) and higher air pollutant concentrations were observed in male children with AR and asthma. CONCLUSION: In children with AR, comorbid asthma was associated with increased rhinitis severity when they were exposed to air pollutants, and the association was only noted in males. Increased nasal obstruction/inflammation from exposure to air pollutants may be the mechanisms underlying this association. IMPACT STATEMENT: The influence of asthma on the severity of rhinitis when children with allergic rhinitis (AR) are exposed to air pollutants has not been studied. In children with AR, the correlation between higher rhinitis discomfort, higher number of clinical visits for AR, and higher PM10, PM2.5, NO2, NMHC concentrations were only noted in those who also had asthma. The correlation was only noted in male. Comorbid asthma was associated with higher rhinitis severity when children with AR are exposed to air pollutants The association was only noted in male.

Educational Videos to Reduce Parental Rejection of Pediatric Cardiac Catheterization during the COVID-19 Pandemic.

During the COVID-19 pandemic, people voluntarily reduced their necessary healthcare. We examined whether supplying educational digital versatile discs (DVDs) before admission can reduce parental rejection of pediatric cardiac catheterization for congenital heart disease (CHD). Parents of 70 children with CHD selected for cardiac catheterization were randomly allocated to the DVD (received pre-admission DVDs in the outpatient department; 70 parents of 35 children) or non-DVD groups (did not receive the DVDs; 70 parents of 35 children). The parents could reject the admission of their children within 7 days. Cardiac catheterization was rejected by 14 (20.0%) and 26 (37.1%) parents in the DVD and non-DVD groups, respectively (p = 0.025). Parent Perceptions of Uncertainty Scale scores were lower in the DVD (128.3 ± 8.9 points) than in the non-DVD group (134.1 ± 7.3 points; p < 0.001). Decreased uncertainty due to pre-admission DVD watching could have contributed to the increased parental willingness for cardiac catheterization. The effects of pre-admission educational DVDs were more significant among parents with a lower education, rural residence, with only one child, female child, or younger child. Offering educational DVDs to parents of children selected for cardiac catheterization for CHD may decrease the parental rejection rate of the treatment.

Allergic rhinitis children with obesity are more vulnerable to air pollution: a cross sectional study.

The association between air pollution, allergic rhinitis (AR), and obesity has not been studied. From 2007 to 2011, 52 obese and 152 non-obese children (7-17 years old) with AR were recruited. Pediatric-Rhinoconjunctivitis-Quality-of-Life Questionnaire (PRQLQ) and nasal peak expiratory flow (NPEF) were tested. Association between the scores and rates of the two tests and mean air pollutant concentrations within 7 days before the tests were compared. When exposed to higher concentrations of CO, PM10, and PM2.5, the rates of worse nasal discomfort were 39.4%, 44.4% and 39.3% in obese children; and 18.0%, 21.9% and 19.7% in non-obese children, respectively. Compare to non-obese children, the rates in obese children were higher for CO (odds ratio (OR) 3.54, 95% confidence interval (CI) 1.15 ~ 10.92); PM10 (OR 3.26, 95% CI 1.01 ~ 10.57) and PM2.5 (OR 3.30; 95% CI 1.03 ~ 10.54). In obese children, correlations between higher concentrations of CO, PM10, PM2.5 and higher nasal discomfort (higher PRQLQ); and correlations between higher concentrations of CO, PM10, PM2.5, NMHC (non-methane hydrocarbon) and higher nasal mucosa inflammation (lower NPEF) were noted. Obesity negatively affected AR severity when AR children experienced higher concentrations of CO, PM10, and PM2.5. Increased nasal inflammation induced by air pollutants might be the underlying mechanism.

Impact of educational videos on maternal anxiety caused by children's heart surgery.

BACKGROUND: Mothers of children undergoing surgery for congenital heart disease experience significant stress. Therefore, finding a strategy to decrease this is vital. AIMS: To examine whether adding educational digital video discs to routine education can reduce maternal anxiety and depression when their children undergo heart surgery and when surgical or post-surgical complications occur. STUDY DESIGN: In a teaching hospital, 120 mothers whose children underwent elective heart surgery were randomly and equally divided into two groups: mothers receiving routine education plus a digital video disc before surgery and mothers receiving only routine education. Mothers' anxiety and depression levels were compared before education, after education (before surgery), and on discharge day. The effect of watching the digital video disc on maternal anxiety and depression on discharge day was evaluated for the participants whose children had surgical or post-surgical complications. RESULTS: Compared with only routine education, mothers' anxiety after education and on the discharge day decreased more if digital video disc was added. Depression decreased more after education, but no difference was found on the discharge day. Anxiety levels of mothers whose children had surgical or post-surgical complications on the discharge day decreased more if they watched the digital video disc, compared with those receiving only routine education (Beck anxiety inventory score 3.4 ± 1.9 and 6.1 ± 2.4 respectively; p-value .001). CONCLUSIONS: Compared with only routine education, adding digital video disc could decrease mothers' anxiety, and until the day of discharge. Compared with only routine education, adding digital video disc could decrease mothers' anxiety on the discharge day if their child had surgical or post-surgical complications. RELEVANCE TO CLINICAL PRACTICE: Adding educational digital video disc to routine education could decrease mothers' anxiety until the day of discharge. It could also decrease mothers' anxiety if their child had surgical or post-surgical complications.

Allergic rhinitis is associated with thromboembolic disease in pregnancy.

Finding the risk factors for thromboembolic (TE) disease and preventing its development in pregnant women is important. Allergic rhinitis (AR) is a common chronic disease. We aim to find if AR is a risk factor. From 2004 to 2011, 55,057 pregnant women were recruited from a Taiwan database. They were grouped into AR and non-AR groups. The rate of TE and venous complications during pregnancy and 60 days after childbirth were compared between non-AR and the AR group. Those with AR diagnosed both before and after childbirth, meaning AR was not changed during pregnancy, the rates of TE (OR 2.64) and venous complications (OR 1.35) were higher compared to non-AR subjects. In those who underwent cesarean delivery, the rate was also higher in group 3 (OR 4.14). Those with AR before childbirth, without after, meaning AR was well controlled during pregnancy, the rate of TE was not higher than that of the non-AR subjects. Pregnant women with AR have an increased rate of TE. An increased rate of venous complications in these subjects might explain the increase in TE. If AR is well controlled during pregnancy, the rate of TE does not appear to increase.

Maternal Exposure to Air Pollution Is Associated with Neonatal Jaundice: A Retrospective Cohort Study.

OBJECTIVE: To evaluate the association between maternal ambient pollutant exposure and neonatal jaundice in multiple pollutant species and examine sex differences. STUDY DESIGN: Epidemiologic study: Records of 13 297 newborns (6153 male, 7144 female) born in Taichung, Taiwan were obtained from a national database. Average concentrations of prenatal air pollutants 3 months prior to birth were divided into low, middle, and high levels. Neonatal jaundice phototherapy rates between mothers who suffered varying air pollutant levels were compared. Clinical study: Three hundred seventy-six newborns (189 male, 187 female) born and received jaundice treatment with phototherapy in a hospital in Taichung, Taiwan were recruited. The correlation between prenatal exposure to air pollutants 3 months prior to birth, newborn's serum bilirubin, and serum hemoglobin were calculated. RESULTS: Epidemiologic study: Male newborns born to mothers exposed to high carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO2), and methane (CH4) levels had higher phototherapy rates. In female newborns, the same was noted for CO and CH4. Clinical study: Male newborns had a positive correlation between CO, ≤2.5 µm diameter particles, ≤10 µm diameter particles, NO, NO2, nonmethane hydrocarbon, and CH4 exposure 3 months prior to birth and serum bilirubin levels. Female newborns had a positive correlation for CH4. A positive correlation between CO, ≤2.5 µm diameter particles, ≤10 µm diameter particles, NO2, nonmethane hydrocarbon, CH4 exposure, and serum hemoglobin levels was noted in male newborns. CONCLUSION: Maternal exposure to air pollutants may increase neonatal jaundice treatment rates for phototherapy and higher neonatal serum total bilirubin level. Higher hemoglobin levels because of higher pollutant exposures may explain our findings. The association was more obvious in male newborns.

Effect of the Fungal Immunomodulatory Protein FIP-fve in the Neutrophilic Asthma Animal Model.

BACKGROUND: Asthma animal models provide valuable information about the pathogenesis and the treatment of asthma. An ovalbumin (OVA)/complete Freund's adjuvant (CFA)-sensitized model was developed to induce neutrophil-dominant asthma and to investigate whether fungal immunomodulatory peptide-fve (FIP-fve) could improve asthma features in the OVA/CFA-sensitized model. METHODS: We used female BALB/c mice and sensitized them intraperitoneally with OVA/CFA on days 1, 2, and 3. On days 14, 17, 21, 24, and 27, they were challenged with intranasal OVA. The airway hyper-responsiveness (AHR) was detected by BUXCO, inflammatory cells were stained with Liu's stain, the cytokines were detected using ELISA, and the airway inflammation was analyzed with hematoxylin and eosin stain. RESULTS: According to the results, OVA/CFA sensitization could induce AHR, high levels of IgE, and inflammatory cells especially neutrophils infiltration in the lung and airway inflammation. IL-4, IL-5, IL-6, IL-8, IL-10, IL-13, IL-17, IL-25, IL-33, and transforming growth factor-ß (TGF-ß) increased in the OVA/CFA-sensitized mice. OVA/CFA-sensitized mice treated with FIP-fve not only increased IL-12 and IFN-γ but also decreased IL-4, IL-5, IL-6, IL-8, IL-13, IL-17, IL-25, IL-33, and TGF-ß in the bronchoalveolar lavage fluid. Moreover, FIP-fve significantly decreased neutrophil infiltration in the lung. CONCLUSION: The OVA/CFA model induced neutrophilic asthma successfully, and FIP-fve improved neutrophil-dominant asthma.

CHA2DS2-VASc Score for Major Adverse Cardiovascular Events Stratification in Patients with Pneumonia with and without Atrial Fibrillation.

BACKGROUND: Recent studies have shown an association between CHA2DS2-VASc (congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, stroke or transient ischemic attack (TIA), vascular disease, age 65 to 74 years, sex category) score and outcome of acute myocardial infarction, stroke, and chest pain. As pneumonia can affect the cardiovascular system, this study aimed to investigate the performance of the CHA2DS2-VASc score for major adverse cardiovascular events (MACEs) risk stratification in patients with pneumonia. METHODS: A retrospective population-based cohort study including 61,843 patients with pneumonia. These patients were divided into two cohorts that were stratified based on the presence or absence of underlying atrial fibrillation (AF). We calculated the CHA2DS2-VASc score and incidence density rates of MACEs in each cohort. Cox regression was conducted to calculate hazard ratio of MACEs in pneumonia patients. The diagnostic performance of CHA2DS2-VASc with regard to MACEs was tested using the receiver operator characteristic curve. RESULTS: Pneumonia patients with higher CHA2DS2-VASc score were more likely develop MACEs in both the AF and non-AF groups. In the AF group, the areas under the curve (AUC), sensitivity, and specificity were 0.824 (0.7773-0.8708), 0.7, and 0.84 respectively. In the non-AF group, the AUC, sensitivity, and specificity were 0.8185 (0.8152-0.8217), 0.75, and 0.83 respectively. CONCLUSIONS: The CHA2DS2-VASc score showed good performance in the prediction of MACE in patients with pneumonia.

Epidemiology and factors associated with mortality of thyroid storm in Taiwan: a nationwide population-based study.

Thyroid storm is a rare and life-threatening disease. However, its prevalence, incidence, and mortality rate in Chinese population are unknown. We performed a retrospective study using the Taiwan Health and Welfare Data. Patients admitted owing to thyrotoxicosis were divided into thyroid storm group and non-thyroid storm group. We assessed thyroid storm prevalence, incidence, complications, and mortality rate. Multiple Cox regression was performed to estimate the hazard ratio for the mortality risk. Overall, 1244 thyroid storm patients and 83,874 thyrotoxicosis patients without thyroid storm were included. Most thyroid storm patients were female (67.9%) with ages ranging from 30 to 44 years (33.4%), and most thyroid storm cases occurred during the summer season. The prevalence of thyroid storm was 1.48% (1244/83,874). The incidence rate of thyroid storm was 0.55 per 100,000 persons per year and 6.28 per 100,000 hospitalized patients per year. The overall 14-, 28-, and 90-day mortality rates of thyroid storm patients were 5.23%, 6.59%, and 8.12%, respectively. Thyroid storm, older age, male, and underlying ischemic stroke, myocardial infarction, heart failure, kidney disease, atrial fibrillation, depression, chronic obstructive pulmonary disease, diabetes mellitus, cancer, end stage renal diseases were associated with a significantly higher risk of mortality. In conclusion, the 90-day mortality rate of thyroid storm was high and was commonly associated with multiorgan failure and shock. Therefore, clinical physicians should identify thyroid storm and treat it accordingly.

Role of biomarkers and effect of FIP-fve in acute and chronic animal asthma models.

BACKGROUND: Asthma is a consequence of complex gene-environment interactions. Exploring the heterogeneity of asthma in different stages is contributing to our understanding of its pathogenesis and the development of new therapeutic strategies, especially in severe cases. OBJECTIVE: This study aimed to further understand the relationship between manifestations of acute and chronic asthma and various endotypes, and explore the severity of lung inflammation, cell types, cytokine/chemokine differences, and the effects of FIP-fve. MATERIALS AND METHODS: Acute and chronic OVA-sensitization mouse asthma models, based on our previously published method, were used and FIP-fve was used to evaluate the effect on these two models. BALF cytokines/chemokines were detected according to the manufacturer's protocol. RESULTS: Seventeen cytokine/chemokine secretions were higher in the chronic stage than in the acute stage. Whether in acute stage or chronic stage, the FIP-fve treatment groups had reduced airway hyperresponsiveness, infiltration of airway inflammatory cells, secretion of cytokines, chemokines by Th2 cells, and TNF-α, IL-8, IL-17, CXCL-1, CXCL-10, CCL-17, and CCL-22, and it was also found that the Treg cell cytokine IL-10 had increased significantly. PCA (Principal Component Analysis) was also used to compare statistics and laboratory data to find the important biomarkers in different stages and after treatment with FIP-fve. CONCLUSIONS: There are many different immune responses in the different stages of the asthma process. Drug treatment at the appropriate times might help reduce the worsening of asthma.

The impact of allergic rhinitis on gastrointestinal disorders among young adults.

BACKGROUND: An association between allergic rhinitis (AR) and digestive diseases (DDs) has been reported; however, studies have only focused on the prevalence of DDs in populations of patients with AR. In individuals with specific DDs, the impact of AR on the frequency of clinical visits for each DD has not been studied. Moreover, the association between topical steroid usage for AR and DDs has not been investigated. METHODS: Data from 16 526 men and 18 438 women, aged 21 to 30 years, were collected from a national database. Individuals were separated into the AR and non-AR groups. Eight common DDs were studied: (1) gastroesophageal reflux disease (GERD), (2) gastritis and duodenitis, (3) peptic ulcers, (4) irritable bowel syndrome, (5) gastric functional disease, (6) intestinal functional disease, (7) gastroenteritis and colitis, and (8) constipation. The rate of each DD was compared between groups. In individuals with specific DDs, the frequency of clinical visits for each DD was also compared between groups. Between users and nonusers of topical steroids in the AR group, the rate of DDs was compared. RESULTS: Significant associations were observed between all eight DDs and AR in both sexes. In comparison to the non-AR group, women with AR visited clinics more frequently for gastritis/duodenitis, gastric and intestinal functional disease, gastroenteritis/colitis, and constipation, while men with AR visited clinics more frequently for gastritis/duodenitis, gastric functional disease, gastroenteritis/colitis, and constipation. Female topical-steroid users with AR had higher rates of GERD, irritable bowel syndrome, gastric or intestinal functional disease, and gastritis/colitis. Male topical-steroid users with AR had higher rates of GERD and peptic ulcers. CONCLUSION: AR was associated with DDs in both sexes. However, the influence of AR on clinical visit frequency varied among specific DD groups. Topical steroid usage for AR was associated with some DDs, but the association requires future evaluation.

Association of alprazolam with major cardiovascular events in patients with hypertension.

RATIONALE: Anxiety is a mediator for emotional reactivity and acute blood pressure elevations, which are associated with an increased risk of cardiovascular death. Alprazolam is a common medication for anxiolysis. We hypothesized that alprazolam usage can reduce the risk of major adverse cardiovascular events (MACEs) in patients with hypertension. METHODS: A retrospective cohort study was performed using datasets from Taiwanese Health and Welfare Data. Patients with hypertension were divided into exposed (Alprazolam-exposed) and control groups (non-Alprazolam-exposed) with 1:1 propensity score matching. The study endpoint was the occurrence of MACE. Adjusted hazard ratio (aHR) of MACE risk was estimated using the multiple Cox proportional hazard model. Age-stratified analysis was performed to evaluate the interaction of age and alprazolam use with MACEs. RESULTS: The study cohort consisted of 335 517 alprazolam-exposed patients and 1:1 PSM controls. The mean age was 63.62 ± 12.71 years in the Alprazolam-exposed population. Alprazolam exposure was significantly associated with reduced risk of MACEs (aHR = 0.965, 95% CI = 0.954-0.977), including ischemic stroke (aHR = 0.958, 95% CI = 0.940-0.976), hemorrhagic stroke (aHR = 0.856, 95% CI = 0.821-0.892), myocardial infarction (aHR = 0.933, 95% CI = 0.900-0.968), sudden cardiac death (aHR = 0.955, 95% CI = 0.916-0.996), and all-cause mortality (aHR = 0.921, 95% CI = 0.909-0.932). In the age-subgroup analysis, alprazolam showed the greatest risk reduction effect in hemorrhagic stroke for patients aged <65 years (aHR = 0.779, 95% CI = 0.727-0.835). CONCLUSION: Alprazolam usage in patients with hypertension was associated with a slightly reduced risk of MACEs and all-cause mortality, and up to 22% reduced risk of hemorrhagic stroke was observed in alprazolam users aged <65 years.

Allergic rhinitis, rather than asthma, might be associated with dental caries, periodontitis, and other oral diseases in adults.

BACKGROUND: The association between asthma (AS), allergic rhinitis (AR) and oral diseases remains inconclusive in adults. AS and AR often coexist. However, studies that investigate AS, AR together and their association with oral diseases are scarce. METHODS: Data from 22,898 men and 28,541 women, aged 21 to 25 years, were collected from a national database in Taiwan. Five common oral diseases: dental caries, periodontitis, pulpitis, gingivitis, and stomatitis/aphthae were studied. Differences in the incidence of the five oral diseases in AR vs. non-AR, and AS vs. non-AS groups were compared. The incidence of the five oral diseases in men/ women, urban/country citizen, and high/low income groups was studied. The frequencies of clinical visits and impact of topical steroid use between the groups were also studied. The confounding factors included sex, socioeconomic status, urbanization, dentofacial anomalies, disease of salivary flow, diabetes mellitus, and esophageal reflux. RESULTS: The incidence and the frequencies of clinical visits for all five oral diseases were higher in those with AR than in the non-AR group after adjusting for confounding factors and AS. Similar observation was made for the AS group, without adjusting for AR. However, if AR was included for adjustment, no relationship was found between AS and oral diseases. In the AR group, those with higher incomes, and country residents had a high risk of developing oral disease. Intranasal steroids, rather than inhaled steroids, were also associated with oral diseases. CONCLUSION: AR, rather than AS, may be associated with oral diseases in young adults.

Gastroenteritis during infancy is a novel risk factor for allergic disease.

Antibiotics during infancy, delivery, and breastfeeding affect the intestinal microbiota in early life and is associated with allergic disease. Gastroenteritis (GE) during infancy also affects intestinal microbiota in early life, however, its relationship to allergic disease has not been investigated.Data of 45,499 males and 49,430 females, from birth to 5 years of age, were collected from a national database in Taiwan. Subjects were categorized into early GE (GE within 0-6 months) and non-early GE group (no GE within 0-6 months). The rates of asthma (AS), allergic rhinitis (AR), and atopic dermatitis (AD) over 5 years were evaluated and compared between the groups. In patients with AS, AR, and AD, the number of clinical visits and drug prescriptions for the allergic disease was also evaluated to assess the effect of early GE on allergic disease.After adjusting for the effect of GE in later life and other factors, the rates of AS [OR (odds ratio) 1.54, 95% confidence interval (CI) 1.48-1.60], AR [OR 1.49, 95% CI 1.45-1.54], and AD [OR 1.40, 95% CI 1.33-1.47] were higher in the early GE group than in the non-early GE group. The magnitude of the increase was higher in females than in males. In those with AS, AR, and AD, the number of clinical visits and drug prescriptions was not different between the early GE and non-early GE groups. In children with early GE, good control of GE in the following years lowered the rate of allergic disease.Early-life GE was associated with increased rates of AS, AR, and AD in later life and this was trend more prominent in females.

Effect of Lactobacillus rhamnosus GG immunopathologic changes in chronic mouse asthma model.

BACKGROUND: Asthma is a heterogeneous inflammatory disorder of the airway. A Th2 response usually contributes to high levels of allergen-specific IgE and eosinophilic airway inflammation. Several findings have demonstrated that neutrophils, not eosinophils, are the major inflammatory cells in chronic asthma patients with steroid-resistance. Lactobacillus rhammosus GG (LGG) exhibits anti-inflammatory properties on OVA-induced acute airway inflammation. OBJECTIVE: We hypothesized that orally administrated LGG should reduce airway remodeling in chronic experimental models. METHODS: Female Balb/c mice were sensitized with OVA. LGG was used to investigate whether oral administrations of LGG inhibited OVA-induced airway inflammation in a chronic asthma model and the different intervention times between LGG pre-treatment and post-treatment groups. BALF was analyzed with Liu's stain and ELISA assay. Lung histopathology was assayed with HE, IHC and Masson's trichrome staining. Lung tissues were assayed with PCR (T-bet, GATA3, RORrt and Foxp3). Many cytokines were detected in the serum and BALF. RESULTS: LGG significantly decreased the number of infiltrating inflammatory cells. We also found that the oral LGG group suppressed not only Th2 cytokine, but also IL-17, TNF-α and HMGB1 in the BALF levels. However, GATA3 and RORrt decreased significantly in the RNA level in the LGG groups, but the T-bet and Foxp3 increased in the RNA level. CONCLUSIONS: LGG not only had anti-inflammatory effects on OVA-induced airway inflammation, but also improved airway remodeling and collagen expression in the chronic asthma mouse model. Moreover, LGG might be an additional or supplementary therapy for allergic airway diseases.

Neonatal Phototherapy: A Novel Therapy to Prevent Allergic Skin Disease for At Least 5 Years.

BACKGROUND: Preventing the development of allergic skin disease in children is the best way to treat the disease. OBJECTIVES: Ultraviolet (UV)-free blue light phototherapy has been reported to treat atopic eczema. We evaluated the effect of neonatal phototherapy on allergic skin disease in children. METHODS: We randomly recruited 117,041 children from an insurance research database. Those with neonatal jaundice and receiving neonatal phototherapy were classified as the icteric-phototherapy group (n = 4,744), those with neonatal jaundice and not receiving phototherapy were classified as the icteric-non-phototherapy group (n = 5,003), and those without jaundice were classified as the non-icteric group (n = 107,294). We reviewed claims from birth to age 5 years. The prevalence of atopic dermatitis (AD), clinical visit times, and topical prescriptions for allergic skin disease at different ages were compared among groups. RESULTS: AD prevalence was lower in the icteric-phototherapy group than in the icteric-non-phototherapy group. Moreover, clinical visit times for allergic skin disease were lower at age 1-4 years, and topical agent prescription for allergic skin disease were lower at age 1-5 years, in the icteric-phototherapy group than in the icteric-non-phototherapy group. The decreased use of topical agents could reach 64.29%. The 5-year complications of skin disease and cancer in the phototherapy group were not higher. CONCLUSIONS: To our knowledge, this is the first study to report on the effect of UV-free blue light therapy on allergic skin disease in newborns. Blue light therapy in newborns may be a novel method to efficiently prevent allergic skin disease for at least 5 years.

Association between allergic disease, sleep-disordered breathing, and childhood nocturnal enuresis: a population-based case-control study.

BACKGROUND: Little is known about the associations between allergic disease, sleep-disordered breathing (SDB), and childhood nocturnal enuresis (NE). We examined whether allergic disease and SDB were associated with childhood NE. METHODS: Data were assessed from the 2007-2012 Taiwan National Health Insurance Research Database. We enrolled 4308 children aged 5-18 years having NE diagnosis and age- and sex-matched 4308 children as the control group. The odds ratios of NE were calculated to determine an association with preexisting allergic disease and SDB. RESULTS: A total of 8616 children were included in the analysis. Prevalence of allergic diseases and SDB was significantly higher for the NE group than the control group (all p < 0.001). After adjusting odds ratios for potential confounding factors, except asthma, children with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and obstructive sleep apnea (OSA) had significantly higher odds of NE compared with children never diagnosed. With stratification for sex, girls with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, OSA, and snoring had significantly higher odds of NE, compared with girls never diagnosed. Only boys with allergic rhinitis and OSA were associated with increased odds of NE. With stratification for age, children aged 5-12 years with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and OSA had significantly higher odds of NE compared with those never diagnosed. Odds of NE increased with the number of comorbid allergic diseases. CONCLUSIONS: Allergic diseases and SDB are associated with increased odds of childhood NE. The odds of NE increased with the number of comorbid allergic diseases present.
