PURPOSE: A longitudinal study was conducted to examine the effects of handwashing and gargling education for children on the prevention of respiratory tract infections (RTIs) in children in Japan. METHODS: The study included 38,554 children born in 2010 who were enrolled in a longitudinal study. Information on children's hygiene education regarding handwashing and gargling was collected in a survey at the age of 3.5 years. Based on parents' reports of doctors' diagnoses, airway infections and influenza events in the 12-month duration before the survey were evaluated for RTIs at the ages of 4.5 and 9 years. Poisson regression with robust variance was performed to examine the effects of hygiene education on RTIs prevention. The supplementary analysis was stratified by household income. RESULTS: Children were categorized into different groups: 38% in the handwashing and gargling group, 29% in the handwashing group, 0.1% in the gargling group, and 9.7% in the no-education group. Exclusions were made for non-respondent children (23%) and those in the gargling group. Hygiene education was associated with decreased influenza at the age of 4.5 years in the handwashing (adjusted RR [aRR] = 0.8; 95% CI, 0.8-0.9) and handwashing and gargling groups (aRR = 0.8; 95% CI, 0.8-0.9) compared with no education. However, no preventive effects on airway infections at the age of 4.5 and 9, influenza at the age of 9, or hospitalization between the ages of 3.5 and 9 years were detected. Handwashing and gargling could significantly prevent influenza in low-income households (aRR = 0.7; 95% CI, 0.6-0.8). Conclusions: Gargling education was widespread and mostly combined with handwashing education in Japan. Hygiene education significantly affected prevention of influenza infections at the age of 4.5 years, especially in low-income households. WHAT IS KNOWN: • Previous intervention studies showed handwashing and gargling are effective in preventing respiratory tract infections. WHAT IS NEW: • We conducted a longitudinal study on handwashing and gargling education in Japanese children and found that handwashing and gargling were widely practiced together. • Handwashing and gargling education were related to a reduction in influenza, particularly in low-income households.

BACKGROUND: Chronic rhinosinusitis (CRS) can be divided into endotypes by functional or pathophysiologic findings. OBJECTIVE: The aim of this study was to analyze the expression of cytokines, prostaglandin (PG) synthases, and their receptors related to the pathogenesis of CRS, especially those contributing to nasal polyp (NP) formation. METHODS: NPs and uncinate tissue (UT) samples were collected from 90 patients who underwent endoscopic sinus surgery. They included 75 patients with CRS (including 45 with eosinophilic CRS [eCRS] and 30 with non-eCRS) and 15 patients without CRS. A total of 30 genes were selected for our original DNA array plate to analyze the levels of expression of 10 cytokines (IFN-γ, IL-4, IL-5, IL-10, IL-13, IL-17A, IL-22, IL-25, IL-33, and TSLP), 4 prostaglandin synthases (prostaglandin D2 [PGD2] synthase, prostaglandin E2 synthase, COX-1, and COX-2), and their 16 receptors. Clustering analysis was performed according to the expression results, and clinical findings of patients from each cluster were investigated. RESULTS: The samples could be divided into 3 clusters. Cluster 1 showed elevated levels of expression of IL4, IL5, IL13, TSLP, IL1RL1 (ST2 [an IL-33 receptor]), HPGDS, and GPR44 (CRTH2, a PGD2 receptor); cluster 2 showed elevated levels of expression of IL17A and PTGES; and cluster 3 showed an elevated level of expression of IL25. Regarding clinical features, the main characteristics of each cluster were as follows: NPs from patients with eCRS for cluster 1, NPs and/or UT samples from patients with non-eCRS for cluster 2, and UTs from patients with non-CRS for cluster 3. CONCLUSION: The results suggest that there are associations between type 2 inflammation/PGD2 and eCRS and also between type 3 inflammation/prostaglandin E2 and non-eCRS.

症例は77歳男性で、2週間前頃から喉頭違和感を自覚しており、当科初診日深夜に呼吸困難が出現したため当院に救急搬送された。精査によりたこつぼ型心筋症と狭心症が明らかとなり、さらにCTで気管狭窄を伴う甲状腺腫瘍が認められた。急速に増大する甲状腺腫瘍であったため、未分化癌や悪性リンパ腫を疑い穿刺吸引細胞診を施行したが、検体不良との結果で診断を得られなかった。早期の確定診断に加え、気道管理の面から経皮的な気道確保への移行が必要と判断し、入院4日目に輪状軟骨開窓術と開放生検を同時に行う方針とした。術後2週目にび漫性大細胞性リンパ腫の確定診断に至り、たこつぼ型心筋症と狭心症は呼吸・循環管理により改善していたため、血液内科に転科のうえ術後21日目から化学療法が開始され、6コース完遂後に腫瘍は完全奏効となった。

Background: The total naso-ocular symptom score (TSS) is widely used as an endpoint to evaluate the severity of seasonal allergic rhinitis. However, it is not a generic preference-based measure. We sought to develop an algorithm for mapping between the TSS and health utility in Japanese cedar pollinosis (JCP). We also performed a cost-utility analysis of sublingual immunotherapy (SLIT) for JCP by using this algorithm. Methods: Patients with JCP filled out the TSS questionnaire and EQ-5D-5L simultaneously during the pollen season in 2019 and in 2020. We estimated a direct utility mapping model by regressing responses to individual TSS questions directly onto utility. The incremental cost-effectiveness ratio (ICER) of active SLIT to a placebo was determined by examining the drug expense and the estimated quality-adjusted life year (QALY) using a dataset from a double-blind placebo-controlled clinical trial. Results: A total of 238 records were included for analysis. The estimated utility decreased with increasing severity of rhinitis. Patients with comorbid asthma showed lower utility. A negative and significant correlation was seen between the TSS and utility in both 2019 and 2020. The estimated equations were: Y(utility) = −0.0161∗X(TSS) + 1.005 in non-asthmatic JCP patients. The ICER of active SLIT to the placebo was estimated to be 4,049,720 and 6,011,218 JPY/QALY in the first and second year, respectively. Conclusions: It is possible to reasonably predict utility from the total naso-ocular symptom score by using regression models. In the estimated algorithm, pre-seasonal SLIT for JCP is cost-effective.

Sinonasal inverted papilloma (SNIP) can recur; however, the factors related to tumor recurrence remain unclear. This study aimed to analyze risk factors, including human papillomavirus (HPV) infection, as well as other factors associated with SNIP recurrence. Thirty-two patients who were diagnosed with SNIP and underwent surgery between 2010 and 2019 were enrolled: 24 men and 8 women, with a mean age of 59.2 years. The mean follow-up was 57.3 months. Demographics and information about history of smoking, diabetes mellitus (DM), hypertension, allergic rhinitis, alcohol consumption, tumor stage, surgical approach, and recurrence were reviewed retrospectively. Specimens were investigated using polymerase chain reaction to detect HPV DNA (high-risk subtypes: 16, 18, 31, 33, 35, 52b, and 58; low-risk subtypes: 6 and 11). Seven patients (21.9%) experienced recurrence. HPV DNA was detected in five (15.6%) patients (high-risk subtypes, n = 2; low-risk subtypes, n = 3). Patients with recurrence of SNIP had a higher proportion of young adults and displayed higher rates of HPV infection, DM, and advanced tumor stage than those without recurrence. HPV infection, young adulthood, DM, and advanced tumor stage could be associated with a high recurrence rate, which suggests that patients with these risk factors could require close follow-up after surgery.

BACKGROUND: Several surgical procedures for posterior nasal neurectomy have been reported, but no conclusion has been reached about which procedure is best. OBJECTIVES: The aim is to evaluate the improvement in symptom medication scores for resection of the posterior nasal nerve trunk in an underwater environment, with submucous inferior turbinectomy, without injuring the sphenopalatine artery (SPA) in severe allergic rhinitis. MATERIAL AND METHODS: Improvements in symptom medication scores were retrospectively compared between 27 consecutive cases who underwent resection of the posterior nasal nerve trunk with turbinoplasty in an underwater environment without injuring the SPA (Underwater group) and, as a historical control, 16 consecutive cases who underwent resection of peripheral branches of the posterior nasal nerve with turbinoplasty (Control group). RESULTS: The improvements in symptom medication scores in the Underwater group were significantly better than in the Control group (3.07 vs. 1.96, p = 0.02). CONCLUSIONS AND SIGNIFICANCE: By using underwater posterior nasal neurectomy, we can easily and safely resect the posterior nasal nerve trunk under a clear surgical view without injuring the SPA. This technique with submucous inferior turbinectomy may, more than resection of peripheral branches of the posterior nasal nerve, be able to reduce the medication score and symptom medication score.

Background: Hyaluronan is one of the major extracellular matrixes in chronic rhinosinusitis (CRS) associated with tissue remodeling. Prostaglandin D2 (PGD2) is also associated with the pathogenesis of CRS. However, little is known about whether PGD2 regulates hyaluronan production by human airway fibroblasts. Objective: We sought to determine the effect of PGD2 on the mRNA expression of three isoforms of membrane-bound hyaluronic acid synthase (HAS1, HAS2 and HAS3) in fibroblasts, the major source of hyaluronan production, derived from CRS patients. Methods: Nasal polyp-derived fibroblasts (NPDF) and uncinate tissue-derived fibroblasts (UTDF) were established from CRS patients with nasal polyps and those without, respectively. These fibroblasts were stimulated with PGD2 or PGD2 receptor (DP/CRTH2)-selective agonists in the presence or absence of receptor-selective antagonists. mRNA levels for HAS1, HAS2 and HAS3 were determined by real-time quantitative PCR. Results: PGD2 (1 µM) significantly enhanced HAS1 but not HAS2 or HAS3 mRNA expression by NPDF. Enhanced HAS1 mRNA expression was also obtained by stimulation with a DP receptor-selective agonist, but not with a CRTH2 receptor-selective agonist. In addition, PGD2-induced HAS1 mRNA expression was significantly inhibited by pre-treatment with DP receptor-selective antagonists. Similar induction of PGD2-induced HAS1 mRNA expression was seen in UTDF. Conclusion: PGD2 selectively stimulates HAS1 mRNA expression in local fibroblasts in CRS via DP, but not CRTH2, receptors.
