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.

Objective  This study aimed to determine whether neonatal hyperbilirubinemia is associated with a risk of autism spectrum disorder (ASD) using a large population-based cohort. Study Design  This retrospective cohort study used data from the children's database (2000–2012) of the National Health Insurance Research Database (1996–2012) in Taiwan. We included neonates who were born between 2000 and 2004 and aged <1 month diagnosed with and without hyperbilirubinemia. The primary outcome was physician-diagnosed ASD. At the end of 2012, multivariate Cox's regression analysis was used to estimate hazard ratios (HRs). Results  A total of 67,017 neonates were included. The neonates with hyperbilirubinemia were associated with 1.28-fold increased risk of ASD (HR = 1.28, 95% confidence interval [CI]: 1.05–1.57) compared with those without hyperbilirubinemia. In subanalysis to determine how phototherapy and exchange transfusion treatment for hyperbilirubinemia were associated with ASD showed no association between treatment and ASD, suggesting the lack of a dose-response effect of hyperbilirubinemia on the risk of ASD. Boys had a nearly six-fold higher risk of ASD than girls (HR = 5.89, 95% CI: 4.41–7.86). Additionally, neonates born with preterm birth and low birth weight were associated with a risk of ASD (HR = 1.46, 95% CI: 1.00–2.13). Conclusion  We did not observe a dose-response effect of hyperbilirubinemia on ASD, but neonatal hyperbilirubinemia may be an independent risk factor for ASD if there is a residual confounding by other perinatal complications. Therefore, this study does not support a causal link between neonatal hyperbilirubinemia exposure and the risk of ASD. [ABSTRACT FROM AUTHOR]

Objective: The association between asthma and benign prostatic hyperplasia (BPH) has rarely been explored. We investigated whether male asthmatic patients had an increased risk of BPH by conducting this retrospective nationwide population-based study.Methods: We utilized data derived from the National Health Insurance Research Database (NHIRD) in Taiwan. A total of 9778 male patients aged >40 years who were newly diagnosed with asthma between 2000 and 2006 were included in the asthma group. Male enrollees without asthma were selected as the non-asthma group from the same database. Both the groups were followed up until the end of 2013. We performed Cox proportional hazard regression analysis to estimate the risk of BPH and transurethral resection of the prostate (TURP) in the male patients with asthma compared with that in those without asthma.Results: The risk of BPH and TURP in the asthma group was 1.40-fold (95% confidence interval [CI] = 1.30-1.42) and 1.30-fold (95% CI= 1.31-1.50) higher than that in the non-asthma group, respectively, after adjusting for comorbidities, relevant medications and number of annual outpatient visits.Conclusions: The male patients with asthma were found to have a higher risk of BPH than did those without asthma.

Background: Type 1 diabetes (T1D) is one of the most common chronic diseases of childhood. Whether neonatal hyperbilirubinaemia increases the risk of T1D remains unclear. Aim: To estimate the association between neonatal hyperbilirubinaemia and phototherapy and the risk of T1D using a large nationwide population-based cohort. Methods: This retrospective study was conducted using data from the National Health Insurance Research Database in Taiwan from 2001 until 2005. Altogether, 23,784 neonates aged <30 days diagnosed with hyperbilirubinaemia and 47,568 neonates without hyperbilirubinaemia were enrolled and frequency-matched to the hyperbilirubinaemia group by gender, age, parental occupation and urbanisation. Cox regression analysis was performed to estimate hazard ratios (HRs) and 95% confidence intervals (CI). Results: Of the 71,352 neonates included, those with hyperbilirubinaemia had a higher incidence of T1D (4.76 vs 2.68 per 10,000 person-years, p < 0.001) and an earlier mean age at onset of T1D [4.13 (2.80) vs 5.80 (2.67) years, p < 0.001] than those without hyperbilirubinaemia. After adjusting for confounding factors in multivariable analysis, the neonates with hyperbilirubinaemia had a 66% increased risk of developing T1D (HR 1.66, 95% CI 1.26–2.18). Girls had a 1.41-fold (HR 1.41, 95% CI 1.10–1.82) greater risk of T1D than boys. Additionally, neonates with a history of perinatal complications (HR 1.66, 95% CI 0.99–2.80) and neonatal infections (HR 2.13, 95% CI 1.45–3.15) had an increased subsequent risk of T1D. Conclusions: The results suggest that neonatal hyperbilirubinaemia is associated with a subsequently increased risk of childhood-onset T1D.
