Comorbidities of chronic rhinosinusitis in children and adults.

BACKGROUND: Chronic rhinosinusitis (CRS) is a chronic inflammatory disease of the nose and paranasal sinuses lasting ≥12 weeks. CRS may exist with (CRSwNP) or without (CRSsNP) nasal polyps. The aim was to evaluate conditions associated with CRS in a randomized hospital cohort. We hypothesized that comorbidities and surgical procedures differ between pediatric and adult patients. METHODS: This study consisted of hospital registry data of a random sample of rhinosinusitis patients (age range 0-89 years) with the diagnosis of J32 or J33, correspondingly, registered during outpatient visits from 2005 to 2019 (n = 1461). The covariates of interest were collected from electronic health records based on ICD-10 codes and keyword searches. RESULTS: Among pediatric patients (n = 104), the relative proportions of CRSsNP and CRSwNP were 86% and 14% respectively. The relative proportions of adult patients (n = 1357) with CRSsNP and CRSwNP were 60% and 40%, respectively. The following comorbidities significantly differed (p < 0.05) between pediatric and adult populations: allergy, chronic otitis media, and tonsillar diseases. In total, 41 % of the children and 46% of the adults underwent baseline endoscopic sinus surgery (ESS). Additional surgeries of the ear, nose and pharynx were significantly more common among children compared with adults. Risk of revision after baseline ESS was associated (p < 0.05) with allergy, asthma, eosinophilia, CRSwNP, immunodeficiency or its suspicion, non-steroidal anti-inflammatory drug exacerbated respiratory disease, and number of any diseases ≥2. CONCLUSIONS: Our study showed that comorbidities differ between pediatric and adult rhinosinusitis patients, as allergy, asthma and allergy, chronic otitis media, mental health disorders, and tonsils disease were significantly more prevalent among pediatric patients. Children and adults were equally treated with ESS. Notably, children underwent additional surgery on adenoids and tonsils more frequently. The effectiveness of ESS in multimorbid adults should be assessed at an individual level.

Cluster Analysis of Finnish Population-Based Adult-Onset Asthma Patients.

BACKGROUND: Phenotypes of adult asthma have been identified in previous studies but rarely in population-based settings. OBJECTIVE: To identify clusters of adult-onset asthma in a Finnish population-based study on subjects born before 1967. METHODS: We used population-based data from 1350 asthmatics with adult-onset asthma (Adult Asthma in Finland) from Finnish national registers. Twenty-eight covariates were selected based on literature. The number of covariates was reduced by using factor analysis before cluster analysis. RESULTS: Five clusters (CLU1-CLU5) were identified, 3 clusters with late-onset adult asthma (onset ≥40 years) and 2 clusters with onset at earlier adulthood (<40 years). Subjects in CLU1 (n = 666) had late-onset asthma and were nonobese, symptomatic, and predominantly female with few respiratory infections during childhood. CLU2 (n = 36) consisted of subjects who had earlier-onset asthma, were predominantly female, obese with allergic asthma, and had recurrent respiratory infections. Subjects in CLU3 (n = 75) were nonobese, older, and predominantly men with late-onset asthma, smoking history, comorbidities, severe asthma, least allergic diseases, low education, many siblings, and childhood in rural areas. CLU4 (n = 218) was a late-onset cluster consisting of obese females with comorbidities, asthma symptoms, and low education level. Subjects in CLU5 (n = 260) had earlier onset asthma, were nonobese, and predominantly allergic females. CONCLUSIONS: Our population-based adult-onset asthma clusters take into account several critical factors such as obesity and smoking, and identified clusters that partially overlap with clusters identified in clinical settings. Results give us a more profound understanding of adult-onset asthma phenotypes and support personalized management.

Radiological score of computed tomography scans predicts revision surgery for chronic rhinosinusitis.

Objective: Evaluate computed tomography (CT) signs that predict need for revision endoscopic sinus surgery (ESS) of chronic rhinosinusitis (CRS). Methods: CRS patients (n = 48) underwent routine sinus CT scans and baseline ESS in 2006-2011. Lund-Mackay (LM) scores and 43 other CT signs were analysed blinded from both sides. Patients filled in a questionnaire during the day of CT scanning. Follow-up data were collected from hospital records until January 2018. Associations were analysed by Fisher's exact, Mann Whitney U, Kaplan-Meier method with logrank test and Cox's proportional hazard model. Results: Total LM score was not significantly associated with the need for revision ESS. The best predictive model was a sum of CT signs of non-detectable anatomy of inferior/middle turbinates, obstructed frontal recess, and previous sinus surgery. Using these CT findings, we formed a Radiological Score (RS) (min-max, 0-3 points). Having at least one RS point was significantly associated with the need for revision ESS during the average follow-up of 10.7 years (p = 0.008, Logrank test). Conclusion: We identified a radiologic score that was able to predict the need for revision ESS, which is probably useful in predicting CRS outcomes.

Tobacco Products, Periodontal Health and Education Level: Cohort Study from Sweden.

BACKGROUND: The aim of this study is to investigate if using tobacco products (including snuff, smoking tobacco and dual-using) associates with periodontal health, education level and mortality in a Swedish cohort, hypothesizing that tobacco products affect periodontal health, associate with lower education and increase the risk of death. METHOD: Study cohort of 1080 subjects aged 31-40 years (528 men, 552 women) was clinically examined and interviewed in 1985 and followed for mortality until 2015. Subjects were classified into two groups: "tobacco users" and "non-users". Associations between periodontal health parameters, tobacco products, education level and age of death were analysed. SPSS was used for analyses. RESULTS: Tobacco products, as well as education level associated, with poor periodontal health. Tobacco users and lower education was linked to higher plaque-, calculus- and gingival-index scores than non-users (p < 0.001). They also had significantly higher prevalence of deep periodontal pockets (≥5 mm) (p < 0.001 and 0.010, respectively), missing teeth (p = 0.010 and 0.003, respectively) and lower education level (p < 0.001) compared with non-users. However, tobacco product users did not die significantly earlier than non-users. CONCLUSION: Tobacco products had a negative impact on periodontal health. Tobacco product users were less educated. However, using tobacco products may not cause premature death.
