Symptom assessment after nasal irrigation with xylitol in the postoperative period of endonasal endoscopic surgery / Avaliação dos sintomas após irrigação nasal com xilitol no período pós-operatório de cirurgias endoscópicas endonasais

Abstract Introduction: Chronic rhinosinusitis is an inflammatory condition of the nasal cavity and the paranasal sinuses that requires multifactorial treatment. Xylitol can be employed with nasal irrigation and can provide better control of the disease. Objective: To evaluate the association between the effects of nasal lavage with saline solution compared to nasal lavage with a xylitol solution. Methods: Fifty-two patients, divided into two groups (n = 26 in the "Xylitol" group and n = 26 in the "Saline solution" group) answered questionnaires validated in Portuguese (NOSE and SNOT-22) about their nasal symptoms and general symptoms, before and after endonasal endoscopic surgery and after a period of 30 days of nasal irrigation. Results: The "Xylitol" group showed significant improvement in pain relief and nasal symptom reduction after surgery and nasal irrigation with xylitol solution (p < 0.001). The "Saline solution" group also showed symptom improvement, but on a smaller scale. Conclusion: This study suggests that the xylitol solution can be useful in the postoperative period after endonasal endoscopic surgery, because it leads to a greater reduction in nasal symptoms.

Efficacy of nasal irrigation with hypertonic saline on chronic rhinosinusitis: systematic review and meta-analysis / Eficácia da irrigação nasal com solução salina hipertônica na rinossinusite crônica: revisão sistemática e metanálise

Abstract Introduction: Currently, several different concentrations of saline are recommended for use in nasal irrigation. Increasing studies show that nasal irrigation with hypertonic saline is more effective than traditional saline in the treatment of rhinosinusitis, but there have been few systematic analyses of the effect of nasal irrigation with hypertonic saline on chronic rhinosinusitis. Objective: We sought to compare the effects of hypertonic saline and isotonic saline in the treatment of rhinosinusitis in order to provide a reference for clinical nasal irrigation for chronic rhinosinusitis treatment. Methods: Medline, cochrane library, EMBASE, PubMed, Chinese biomedical journal database, China national knowledge infrastructure, Wanfang database, and other databases were searched, and the searching was supplemented by manual searches for relevant references to treatment of rhinosinusitis by saline nasal irrigation. The last retrieval date was March 2018. The included studies were evaluated for quality, and data were extracted for meta-analysis using RevMan 5.3. Results: Seven studies were included. Effects favoring hypertonic saline on nasal symptoms were greater in 4 subgroups. These were (1) patients with nasal secretion (SMD = 1.52; 95% CI: 1.04, 2.00; p < 0.01), (2) patients with congestion (SMD = 1.52; 95% CI: 1.04, 2.00; p < 0.01), (3) patients with headache (SMD = 0.82; 95% CI: 0.38, 1.26; p < 0.01), (4) patients with overall symptomatic relief (SMD = 1.63; 95% CI: 0.83, 2.44; p < 0.01). However, no difference was shown in smell improvement (SMD = 0.47; 95% CI: −0.65, 1.59; p = 0.41) and radiologic scores improvement (SMD = 2.44; 95% CI: -3.14, 8.02; p < 0.01). Besides, hypertonic saline showed greater improvement in mucociliary clearance time scores than did the isotonic saline group (SMD = 1.19; 95% CI: 0.78, 1.60; p < 0.01). Hypertonic saline brought greater minor adverse effects. Conclusion: Compared with isotonic saline, hypertonic saline nasal irrigation for the treatment of chronic rhinosinusitis is significantly more effective and has mild side effects in improving nasal symptoms and ciliary movement, but there is no significant difference in imaging findings and smell improvement. Although hypertonic saline is worthy of widespread use in clinical practice, it is still necessary to further study the exact manner and concentration of nasal irrigation.

Resumo Introdução: Atualmente, o uso de várias concentrações diferentes de solução salina é recomendado na irrigação nasal. Um número crescente de estudos mostra que a irrigação nasal com solução salina hipertônica é mais eficaz do que a solução salina tradicional no tratamento de rinossinusite, mas existem poucas análises sistemáticas do efeito da irrigação nasal com solução salina hipertônica em rinossinusite crônica. Objetivo: Comparar os efeitos da solução salina hipertônica com a solução salina isotônica no tratamento da rinossinusite, para fornecer uma referência clínica de irrigação nasal no tratamento da rinossinusite crônica. Método: Foram pesquisados os bancos de dados Medline, Cochrane Library, Embase, PubMed, Chinese biomedical journal database, China national knowledge infrastructure, Wanfang database e outros, e a pesquisa foi complementada por pesquisas manuais de referências relevantes ao tratamento da rinossinusite por irrigação nasal com solução salina. A data da última recuperação de dados foi março de 2018. Os estudos incluídos foram avaliados quanto à qualidade e os dados foram extraídos para a metanálise com o software RevMan 5.3. Resultados: Sete estudos foram incluídos. Os efeitos favoráveis à solução salina hipertônica nos sintomas nasais foram maiores em quatro subgrupos. Esses foram (1) pacientes com secreção nasal (DMP = 1,52; IC95%: 1,04, 2,00; p ˂ 0,01); (2) pacientes com congestão (DMP = 1,52; IC95%: 1,04, 2,00; p ˂ 0,01); (3) Pacientes com dor de cabeça (DMP = 0,82; IC95%: 0,38, 1,26; p ˂ 0,01); (4) Pacientes com alívio sintomático geral (DMP = 1,63; IC95%: 0,83, 2,44; p ˂ 0,01). Entretanto, não houve diferença na melhoria do olfato (DMP = 0,47; IC95%: -0,65, 1,59; p = 0,41) e na melhoria dos escores radiológicos (DMP = 2,44; IC95%: -3,14, 8,02; p < 0,01). Além disso, o grupo solução salina hipertônica mostrou maior melhoria nos escores do tempo de clearence mucociliar do que o grupo solução salina isotônica (DMP = 1,19; IC95%: 0,78, 1,60; p ˂ 0,01). A solução salina hipertônica causou efeitos adversos menores. Conclusão: Em comparação com a solução salina isotônica, a irrigação nasal com solução salina hipertônica para o tratamento da rinossinusite crônica é significantemente mais eficaz e apresenta efeitos colaterais mais leves, melhoria mais acentuada dos sintomas nasais e no movimento ciliar, mas não há diferença significante nos achados de imagem e na melhoria do olfato. Embora a solução salina hipertônica seja digna de uso generalizado na prática clínica, ainda são necessários mais estudos sobre a forma de uso e a concentração ideal da solução nasal.

Nasal lavage cytology and mucosal histopathological alterations in patients with rhinitis / Citologia do lavado nasal e alterações histopatológicas na mucosa nasal de pacientescom rinite

Abstract Introduction The extent of epithelial lesion in allergic and non-allergic rhinitis and its association with inflammatory changes in nasal lavage has not been clarified. Objective To verify the association between the inflammatory cells in the nasal lavage, epithelial lesion extent and basement membrane thickness, in the nasal mucosa of patients with rhinitis; to determine the cutoff point of the percentage of eosinophils in the nasal lavage associated with the atopic patients. Methods Patients with rhinitis and indication for septoplasty and (or) turbinectomy for turbinate hypertrophy were selected, and were submitted to allergy skin tests, nasal lavage with measurement of albumin and interleukin-8 levels, total and differential counting of cells, and mucosal histopathological analysis to determine the extent of epithelial lesion, and degree of basement membrane thickening. Results Fifty-six patients with a median age of 24.5 years and a diagnosis of allergic rhinitis (n = 36) and non-allergic rhinitis (n = 20) were studied. In atopic subjects, allergy skin tests were positive for Dermatophagoides pteronyssinus in 35 (97.0%) and Lolium perenne in 18 (50.0%). Atopic subjects showed a higher clinical score index of rhinitis compared to non-atopic ones. The total count of cells, neutrophils, and levels of albumin and IL-8 were not different in the nasal lavage of atopic and non-atopic subjects. The cutoff point for eosinophil count in nasal fluid for the distinction between allergic rhinitis and non-allergic rhinitis was 4%. Some degree of epithelial lesion was more frequent in allergic rhinitis (94%) than in non-allergic rhinitis (65%) patients. In the presence of basement membrane thickness, as a marker of remodeling, there was no difference in the nasal lavage of patients with allergic rhinitis and non-allergic rhinitis. Conclusion In this series, 4% was the cutoff point for the number of eosinophils in the nasal lavage, for atopy differentiation. Upper airway remodeling accessed by basement membrane thickness showed similar inflammatory cell infiltrate in the nasal lavage, regardless of the presence of atopy.

Resumo Introdução A extensão da lesão epitelial na rinite alérgica e não alérgica e sua associação com alterações inflamatórias no lavado nasal ainda não estão esclarecidas. Objetivo Verificar a relação entre o processo inflamatório no lavado nasal, extensão da lesão epitelial e espessamento da membrana basal na mucosa nasal de pacientes com rinite; determinar o ponto de corte do percentual de eosinófilos no lavado nasal associado à presença de atopia. Método Foram selecionados pacientes com rinite e indicação de septoplastia e (ou) turbinectomia por hipertrofia de conchas nasais, os quais foram submetidos aos testes cutâneos alérgicos, lavado nasal com determinação das concentrações de albumina, interleucina-8 (IL-8), contagem total e diferencial de células, análise da extensão da lesão epitelial, e grau de espessamento da membrana basal por meio de histopatologia da mucosa. Resultado Foram estudados 56 pacientes, mediana de 24,5 anos com diagnóstico de rinite alérgica (n = 36) e rinite não alérgica (n = 20). Nos atópicos os testes cutâneos alérgicos foram positivos para D. pteronyssinus em 35 (97,0%) e L. perenne em 18 (50,0%). Atópicos apresentaram maior índice de escore clínico para rinite em comparação a não atópicos. A contagem total de células, neutrófilos e níveis de albumina e IL-8 não foi diferente entre o lavado nasal de atópicos e não atópicos. O ponto de corte da contagem de eosinófilos no fluido nasal para a distinção de rinite alérgica e rinite não alérgica foi de 4%. Algum grau de lesão epitelial foi mais frequente em pacientes com rinite alérgica (94%) do que em pacientes com rinite não alérgica (65%). Na presença de espessamento da membrana basal, como marcador de remodelamento, não houve diferença no lavado nasal entre pacientes com rinite alérgica e não alérgica. Conclusão Nesta casuística, 4% foi o ponto de corte do número de eosinófilos no lavado nasal, para diferenciação de atopia. Remodelamento da via aérea superior pelo espessamento da membrana basal revelou infiltrado semelhante de células inflamatórias no lavado nasal, independentemente da presença de atopia.

Soluções salinas em diferentes temperaturas e concentrações melhoram o pico de fluxo inspiratório nasal em escolares? / Do saline solutions at different temperatures and concentrations improve peak nasal inspiratory flow in students?

Introdução: A higiene nasal com solução salina mostrou aliviar a congestão, manter a cavidade nasal limpa e úmida e reduzir o espessamento do muco. Evidências que apoiam solução salina aquecida ou solução salina à temperatura ambiente, em diferentes concentrações, são controversas. Objetivo: Avaliar se soluções salinas aquecidas, em diferentes concentrações, são melhores que soluções salinas em temperatura ambiente para aumentar o fluxo inspiratório nasal em crianças saudáveis. Métodos: Estudantes entre 8 e 12 anos de idade foram submetidos a quatro procedimentos com soluções salinas em diferentes concentrações e temperaturas. O pico de fluxo inspiratório nasal foi medido antes e 30 minutos após cada procedimento. A análise estatística foi realizada por meio do teste t de Student, considerando p < 0,05. Resultados: Avaliamos 46 crianças em todas as etapas, cada criança foi controle de si mesma. Solução salina a 3% apresentou melhores resultados, mas não houve diferença significativa no pico de fluxo inspiratório nasal quando comparadas solução salina a 0,9% e solução salina a 3%, aquecida ou em temperatura ambiente. Quando perguntado, as crianças prefeririam solução salina a 0,9% e aquecida. Conclusão: A solução salina a 3% apresentou maiores médias de pico de fluxo inspiratório nasal, mas não foi significativamente superior à solução salina a 0,9%. A solução salina aquecida não foi superior à solução salina em temperatura ambiente. É importante oferecer várias opções aos pacientes.

Introduction: Nasal hygiene with saline has been shown to relieve congestion, keep nasal cavity clean and moist, and reduce thickened mucus. Evidence supporting warmed saline or room temperature saline at different concentrations are controversial. Objective: To evaluate whether warmed saline at different concentrations is better than room temperature saline for improving peak nasal inspiratory flow in healthy children. Methods: Students between 8 and 12 years of age underwent 4 procedures with saline solutions at different concentrations and temperatures. Peak nasal inspiratory flow was measured before and 30 minutes after each procedure. Statistical analysis was performed using Student's t-test, with p < 0.05. Results: We evaluated 46 children at all stages, and each child was self-controlled. Three percent saline had better results, but there was no significant difference in peak nasal inspiratory flow when compared to 0.9% saline, either warmed or at room temperature. Children reported preferring warmed 0.9% saline. Conclusion: Three percent saline had higher mean nasal inspiratory peak flow, but it was not significantly different from 0.9% saline. Warmed saline was not superior to room temperature saline. Providing patients with various options is important.

The effect of different nasal irrigation solutions following septoplasty and concha radiofrequency: a prospective randomized study / Efeito de diferentes soluções para irrigação nasal após septoplastia e radiofrequência das conchas nasais: estudo prospectivo e randomizado

Abstract Introduction Nasal irrigation solutions are widely used following endonasal surgery. These irrigation solutions remove infective debris and crusts, reducing the probability of synechia formation, and accelerate mucosal healing. Objective The aim of the present study was to compare the effects of nasal irrigation solutions with different contents following septoplasty and concha radiofrequency. Methods The present study was a prospective, randomized, controlled simple blind study of 120 patients who underwent septoplasty and bilateral concha radiofrequency. Patients were divided into four groups according to the nasal irrigation solution used: tap water, buffered isotonic saline, saline with xylitol, and hypertonic sea water. Patients were examined on the 7th and 15th postoperative days. A saccharine test was applied to determine mucociliary activity preoperatively and on the 7th and 15th postoperative days. Patients were asked about drying and obstruction using a 10 cm visual analog scale. In addition, patients were examined to determine the crusting score. Results There was no significant difference found in the preoperative and 7th and 15th postoperative days' mucociliary clearance times among the four groups. The crusting score was found to be significantly lower in the hypertonic sea water group (p < 0.001). Drying and obstruction on the 7th and 15th postoperative days were found to be significantly more comfortable in the hypertonic sea water group (p < 0.001). Conclusion Hypertonic sea water is the recommended irrigation solution, as it is associated with less crusting, drying, and obstruction in the nose for the postoperative period following septoplasty and concha radiofrequency.

Essas soluções removem os resíduos e crostas, reduzem a probabilidade de formação de sinéquias e aceleram a cicatrização da mucosa. Objetivo O objetivo do presente estudo foi comparar os efeitos das soluçoes para irrigaçao nasal com diferentes conteudos apos septoplastia e turbinoplastia com radiofrequencia. Método O presente estudo foi um estudo cego simples, randomizado, controlado e prospectivo de 120 pacientes submetidos a septoplastia e turbinoplastia bilateral com radiofrequencia. Os pacientes foram divididos em quatro grupos de acordo com a soluçao nasal utilizada: agua da torneira, soluçao salina isotonica tamponada, soluçao salina com xilitol e agua do mar hipertonica. Os pacientes foram examinados no 7° e 15° dias do pos-operatorio. O teste de sacarina foi utilizado para determinar a atividade mucociliar pre-operatoria e no 7° e 15° dias do pos-operatorio. Os pacientes foram questionados sobre a sensaçao de secura e obstruçao nasais utilizando uma escala visual analógica de 10 cm. Alem disso, os pacientes foram examinados para determinar o escore em relaçao a crostas. Resultados Não houve diferença significativa entre o pré-operatório e o sétimo e 15° dias do pós-operatório dos tempos de clearance mucociliar entre os quatro grupos. Verificou-se que o escore em relação a crostas foi significativamente menor no grupo que usou água do mar hipertônica (p < 0,001). As sensações de secura e obstrução nasais no sétimo e 15° dias do pós-operatório mostraram-se significativamente mais confortáveis no grupo água do mar hipertônica (p < 0,001). Conclusão A água de mar hipertônica é a solução de irrigação recomendada, pois está associada a menor incidência de crostas, secura e obstrução nasais no pós-operatório de cirurgia de septoplastia e das conchas nasais com radiofrequência.

The Effectiveness of Budesonide Nasal Irrigation After Endoscopic Sinus Surgery in Chronic Rhinosinusitis With Asthma

OBJECTIVES: Budesonide nasal irrigation was introduced recently for postoperative management of patients with chronic rhinosinusitis. The safety and therapeutic effectiveness of this procedure is becoming accepted by many physicians. The objective of this study was to evaluate the efficacy of postoperative steroid irrigation in patients with chronic rhinosinusitis and asthma. METHODS: This prospective study involved 12 chronic rhinosinusitis patients with nasal polyps and asthma who received oral steroid treatment for recurring or worsening disease. The 22-item Sinonasal Outcomes Test (SNOT-22) and Lund-Kennedy endoscopy scores were checked before nasal budesonide irrigation, and 1, 2, 4, and 6 months after irrigation. We also calculated the total amount of oral steroids and inhaled steroids in the 6 months before irrigation and the 6 months after it. RESULTS: The mean SNOT-22 score improved from 30.8±14.4 before irrigation to 14.2±8.7 after 6 months of irrigation (P=0.030). The endoscopy score also improved from 7.4±4.7 before irrigation to 2.2±2.7 after 6 months (P<0.001). The total amount of oral steroid was decreased from 397.8±97.6 mg over the 6 months before irrigation to 72.7±99.7 mg over the 6 months after irrigation (P<0.001). CONCLUSION: Nasal irrigation with budesonide is an effective postoperative treatment for chronic rhinosinusitis with asthma, which recurs frequently, reducing the oral steroid intake.

Topical therapy with high-volume budesonide nasal irrigations in difficult-to-treat chronic rhinosinusitis / Terapia tópica de irrigação nasal de alto volume com solução de budesonida em rinossinusite crônica de difícil tratamento

ABSTRACT INTRODUCTION: Chronic rhinosinusitis (CRS) is termed difficult-to-treat when patients do not reach acceptable level of control despite adequate surgery, intranasal corticosteroid treatment and up to 2 short courses of systemic antibiotics or corticosteroids in the preceding year. Recently, high-volume corticosteroid nasal irrigations have been recommended for CRS treatment. OBJECTIVE: To assess high-volume budesonide nasal irrigations for difficult-to-treat CRS. METHODS: Prospective uncontrolled intervention trial. Participants were assessed before- and 3 months after nasal irrigation with 1 mg of budesonide in 500 mL of saline solution daily for 2 days. Subjective (satisfactory clinical improvement) and objective (SNOT-22 questionnaire and Lund-Kennedy endoscopic scores) assessments were performed. RESULTS: Sixteen patients were included, and 13 (81.3%) described satisfactory clinical improvement. SNOT-22 mean scores (50.2-29.6; p = 0.006) and Lund-Kennedy mean scores (8.8-5.1; p = 0.01) improved significantly. Individually, 75% of patients improved SNOT-22 scores, and 75% improved Lund-Kennedy scores after high volume budesonide nasal irrigations. CONCLUSION: High-volume corticosteroid nasal irrigations are a good option in difficult-to-treat CRS control of disease, reaching 81.3% success control and significant improvement of SNOT-22 and Lund-Kennedy scores.

RESUMO INTRODUÇÃO: A rinossinusite crônica (RSC) de difícil tratamento é aquela inadequadamente controlada com cirurgia, corticosteroides tópicos em spray e até dois ciclos de medicação sistêmica em um ano. Atualmente, tem sido preconizado o uso de irrigações nasais de corticosteroides em alto volume para seu tratamento. OBJETIVO: Avaliar o uso da terapia tópica de irrigações nasais com budesonida em alto volume nos pacientes com RSC de difícil tratamento. MÉTODO: Estudo prospectivo de intervenção não controlado em RSC de difícil tratamento com 3 meses de terapia tópica de irrigação (1 mg de budesonida diluído em 500 mL de soro fisiológico para ser utilizado em dois dias). Realizada avaliação subjetiva (melhora clínica satisfatória) e objetiva (questionário SNOT-22 e classificação endoscópica de Lund-Kennedy). RESULTADOS: Foram incluídos 16 pacientes, sendo que 13 (81,3%) consideraram sua melhora clínica satisfatória. Houve melhora significante das médias de SNOT-22 (50,2 a 29,6; p = 0,006) e de Lund-Kennedy (8,8 a 5,1; p = 0,01). Individualmente, 75% dos pacientes apresentaram melhora do SNOT-22 e 75%, do Lund-Kennedy. CONCLUSÃO: A terapia tópica de irrigação de alto volume de corticosteroide é uma boa opção no controle clínico dos pacientes com rinossinusite crônica de difícil tratamento, com controle adequado de 81,3% destes pacientes e melhora significante do SNOT-22 e do Lund-Kennedy.

Clinical analysis of nasal resistance and pulmonary function testing in patients with chronic nasal-sinusitis and nasal polyps / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the pulmonary function and nasal resistance characteristics of patients with chronic nose-sinusitis and nasal polyps (CRSwNP), to explore the evaluation role of nasal resistance in nasal ventilation function and the effect of endoscopic sinus surgery on pulmonary function in patients with CRSwNP.@*METHOD@#Fifty CRSwNP patients that met the study criteria were selected . The patients were performed endoscopic surgeries according to Messerklinger surgical procedures under general anesthesia. Extent of surgery was based on preoperative CT showing the range of the lesion of disease and endoscopic findings. Perioperative treatments contained intranasal corticosteroids, cephalosporin or penicillin antibiotics, nasal irrigation and other treatments. Main outcome measures included visual analog scale (VAS), endoscopic Lind-Kennedy scores, nasal resistence, pulmonary function in patientsone week before and after surgery, three months and six months after surgery. Pulmonary function includes forced expiratory volume in one second (FEV1), forced vital capacity FEV1/FVC and peak expiratory flow (PEF).@*RESULT@#The study found that there were significantly positive correlations among VAS score, Lund-Kennedy score and nasal resistance (P < 0.05) in CRSwNP patients, but there is a significantly negative correlation between VAS score, Lund-Kennedy score, nasal resistance and pulmonary function indexes of FEV1, FVC and PEF (P < 0.05). The VAS score, Lund-Kennedy score and nasal resistance values of CRSwNP patients were decreased significantly after comprehensive treatments with nasal endoscopic operation as the major one, the difference was statistically different (P < 0.05). And the pulmonary function indexs (FEV1, FVC, PEF) were significantly increased after surgery in CRSwNP patients.@*CONCLUSION@#The nasal resistance can objectively and reliably reflect the degree of nasal congestion and the recovery of nasal function in CRSwNP patients after endoscopic sinus surgery. The detection method of nasal resistance is simple. Functional endoscopic sinus surgery can effectively improve the pulmonary ventilation function in CRSwNP patients, providing some clinical references about the prevention and treatment of CRS related lower respiratory disease.

The cure rate was 87.5%. The asthma symptoms were improved in 9 patients (P < 0.01), compared to 2 before surgery. The numbers of patients with improved symptoms were increased from 2 before the surgery to 9 after the surgery.@*CONCLUSION@#As the main treatment, endoscopic si- nus surgery was effective on CRS with asthma.

The effect of hypertonic seawater and isotonic seawater for nasal mucosa of allergic rhinitis mice model / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the effect of hypertonic seawater and isotonic seawater for nasal mucosa of allergic rhinitis mice model, and explore the possible mechanism of nasal irrigation with seawater in treatment of allergic rhinitis.@*METHOD@#We used Der pl to make allergic rhinitis model of BALB/c mice, and divided them into three groups randomly. Nasal irrigation with hypertonic seawater (HS) or isotonic seawater (IS) in the treatment group 1-14 days after modeling, and black control (BC) group was given no treatment after modeling. Normal control (NC) group was given no treatment, the number of rubs and sneezings in each group were counted in 30 min after the last nasal irrigation. Mice were then killed 24 h after the last therapy. The noses of mice from each group were removed and fixed, then the slices were stained with hematoxylin and eosin, the others were observed by transmission electron microscope.@*RESULT@#Mice with hypertonic seawater and isotonic seawater were significantly improved in rubs and sneezings compared to the black control group (P 0. 05); Ciliated columnar epithelium cells in mucosal tissues of HS group and IS group were arranged trimly, better than that in the black control group. Morphology and microstructure in nasal mucosal of HS group was closer to the normal group than in IS group.@*CONCLUSION@#The injury of nasal mucosa ciliated epithelium was significantly improved by nasal irrigation with hypertonic seawater and isotonic seawater, and the former is better than the latter, the mechanism of nasal irrigation with seawater in treatment of allergic rhinitis may rely on repairing the injured nasal mucosa ciliated epithelium, thereby the symptoms of nasal was reduced.

The effect of nasal irrigation in the treatment of allergic rhinitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To compare the symptoms and lower airway inflammatory factors of patients with allergic rhinitis (AR), and to observe the effect of nasal irrigation in the treatment of allergic rhinitis.@*METHOD@#Sixty-one cases diagnosed as AR after skin prick test (SPT)were selected and randomly divided into three groups: 17 patients in group A used nasal steroid spray; 21 cases in group B used nasal irrigation; 23 patients in group C combined ir rigation with nasal steroid. Before and after 3 months treatment, nasal visual analogue scale (VAS) score, rhino conjunctivtis quality of life questionnaire (RQLQ) score, fractional exhaled nitric oxide (FENO) values were observed and compared in each group.@*RESULT@#Before treatment, there is no statistically difference between three groups (P > 0.05). After 3 months of treatment, VAS, RQLQ, FENO of all patients was significantly decreased (P 0.05), FENO value has no statistically significant difference between group A and group B (P > 0.05), but were less than that in group C (P < 0.05).@*CONCLUSION@#Nasal irrigation can ameliorate nasal symptoms, improve quality of life, decrease lower airway inflammation of allergic rhinitis patients. Nasal irrigation is an effective treatment of allergic rhinitis. Nasal irrigation combined with nasal steroid can achieve more significant efficacy.

A comparison of the efficacy of amoxicillin and nasal irrigation in treatment of acute sinusitis in children / 소아과

PURPOSE: The efficacy of antibiotic therapy for acute sinusitis is controversial. This study aimed to compare the efficacies of amoxicillin with nasal irrigation and nasal irrigation alone for acute sinusitis in children. METHODS: This randomized, double-blind, controlled study included 80 children aged 4-15 years with a clinical presentation of acute sinusitis. Patients were randomly assigned to receive either amoxicillin (80 mg/kg/day) in 3 divided doses orally for 14 days with saline nasal irrigation (for 5 days) and 0.25% phenylephrine (for 2 days) or the same treatment without amoxicillin. Clinical improvements in their initial symptoms were assessed on days 3, 14, 21, and 28. RESULTS: On day 3, patients in the amoxicillin with nasal irrigation group showed significant clinical improvement (P=0.001), but there was no significant difference in the degree of improvement between the amoxicillin with nasal irrigation and nasal irrigation alone groups during follow-up (P>0.05). In addition, no significant differences were seen in age, sex, and degree of improvement between groups (P>0.05). CONCLUSION: High-dose amoxicillin with saline nasal irrigation relieved acute sinusitis symptoms faster and more often than saline nasal irrigation alone. However, antibiotic treatment for acute sinusitis confers only a small therapeutic benefit over nasal irrigation.

pH in exhaled breath condensate and nasal lavage as a biomarker of air pollution-related inflammation in street traffic-controllers and office-workers

OBJECTIVE: To utilize low-cost and simple methods to assess airway and lung inflammation biomarkers related to air pollution. METHODS: A total of 87 male, non-smoking, healthy subjects working as street traffic-controllers or office-workers were examined to determine carbon monoxide in exhaled breath and to measure the pH in nasal lavage fluid and exhaled breath condensate. Air pollution exposure was measured by particulate matter concentration, and data were obtained from fixed monitoring stations (8-h work intervals per day, during the 5 consecutive days prior to the study). RESULTS: Exhaled carbon monoxide was two-fold greater in traffic-controllers than in office-workers. The mean pH values were 8.12 in exhaled breath condensate and 7.99 in nasal lavage fluid in office-workers; these values were lower in traffic-controllers (7.80 and 7.30, respectively). Both groups presented similar cytokines concentrations in both substrates, however, IL-1β and IL-8 were elevated in nasal lavage fluid compared with exhaled breath condensate. The particulate matter concentration was greater at the workplace of traffic-controllers compared with that of office-workers. CONCLUSION: The pH values of nasal lavage fluid and exhaled breath condensate are important, robust, easy to measure and reproducible biomarkers that can be used to monitor occupational exposure to air pollution. Additionally, traffic-controllers are at an increased risk of airway and lung inflammation during their occupational activities compared with office-workers. .

Obstrução nasal com ênfase em higienização / Nasal obstruction with emphasis on higienization

A obstrução nasal é uma queixa frequentemente observada na infância. Embora seu impacto na função nasal e sua relação com outras doenças estejam bem estabelecidas, nem sempre é valorizada, muitas vezes passando despercebida. Apesar de ser, em geral, causada por alterações anatômicas ou funcionais do nariz, a obstrução nasal pode ser simplesmente um reflexo das funções fisiológicas normais. A criança com obstrução nasal pode apresentar desde um quadro inócuo de rinorreia até uma situação de risco de morte, com insuficiência respiratória e dificuldades de alimentação. De maneira geral, sua abordagem requer uma anamnese cuidadosa e o exame das fossas nasais e estruturas adjacentes, de forma a determinar se a causa é de origem local ou sistêmica. Deve ser sempre interrogado a respeito da uni ou bilateralidade, intensidade do sintoma (obstrução total ou parcial), periodicidade (constante ou intermitente), duração da queixa, modo de aparecimento (súbita ou progressiva) e idade do paciente. Na maioria dos casos o exame da cavidade nasal pode determinar o local exato da obstrução; no entanto, quando necessário, exames de imagem são utilizados para a complementação do diagnóstico. O tratamento dependerá da intensidade dos sintomas, do tipo e da localização da lesão.Neste artigo serão abordadas as causas mais frequentes de obstrução nasal na infância, os principais métodos de investigação e a abordagem terapêutica geral, sendo enfatizada a importância da higienização nasal para a otimização do tratamento. Desse modo, os médicos que lidam com crianças podem se familiarizar com as possíveis causas de obstrução nasal nesta faixa etária e oferecer as melhores e mais seguras opções terapêuticas disponíveis na atualidade...
