Variations in peak nasal inspiratory flow among healthy students after using saline solutions / Variações do pico de fluxo inspiratório nasal entre escolares sadios após o uso de soluções salinas

ABSTRACT INTRODUCTION: Nasal hygiene with saline solutions has been shown to relieve congestion, reduce the thickening of the mucus and keep nasal cavity clean and moist. OBJECTIVE: Evaluating whether saline solutions improve nasal inspiratory flow among healthy children. METHODS: Students between 8 and 11 years of age underwent 6 procedures with saline solutions at different concentrations. The peak nasal inspiratory flow was measured before and 30 min after each procedure. Statistical analysis was performed by means of t test, analysis of variance, and Tukey's test, considering p < 0.05. RESULTS: We evaluated 124 children at all stages. There were differences on the way a same concentration was used. There was no difference between 0.9% saline solution and 3% saline solution by using a syringe. CONCLUSION: The 3% saline solution had higher averages of peak nasal inspiratory flow, but it was not significantly higher than the 0.9% saline solution. It is important to offer various options to patients.

RESUMO INTRODUÇÃO: A higiene nasal com soluções salinas tem sido indicada para aliviar a congestão, reduzir o espessamento do muco e manter a cavidade nasal limpa e úmida. OBJETIVO: Avaliar se as soluções salinas melhoram o fluxo inspiratório nasal entre crianças sadias. MÉTODO: Escolares com idades entre 8 e 11 anos foram submetidos a 6 procedimentos com soluções salinas em diferentes concentrações. 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, análise de variância e teste de Tukey, considerando p < 0,05. RESULTADOS: Foram avaliadas 124 crianças em todas as etapas. Houve diferenças quanto à forma de uso de uma mesma concentração. Não houve diferença entre solução salina a 0,9% e solução salina a 3% por meio de seringa. CONCLUSÕES: A solução salina a 3% obteve maiores médias do pico de fluxo inspiratório nasal, porém não foi significativamente superior à solução salina a 0,9%. É importante oferecer diferentes opções aos pacientes.

Nasal Myiasis

BACKGROUND: Nasal myiasis is very distressing condition of the nose that occurs among patients with atrophic rhinitis. This condition is frequently found among those belonging to the lower socioeconomic status suffering from bad nasal hygienic conditions. A retrospective study was done of 58 cases of patients admitted for nasal myiasis. All the patients belonged to the lower socio- economic class and suffered from poor hygienic condition. The majority of the patients were over the age of 60 years and male female ratio was 1 : 1.5 .The primary complaints of this condition were epistaxis, foul smelling nasal discharge, passage of worms from the nose and pain. The majority of the patients were suffering from primary atrophic rhinitis and a few from the secondary atrophic rhinitis due to syphilis and leprosy. TREATMENT: As a first step of treatment, the maggots were removed manually and endoscopically. All the patients became maggot free in 2-3 days time. Alkaline nasal douching was then started along with 25% glucose in glycerine nasal drop. Complications such as septal perforation, saddling nose, palatal perforation were observed in a few cases. The incomplete closure of nose (modified Young's operation) was performed in a few cases. CONCLUSION: Manual and endoscopic removal should be done repeatedly. Antimeningitis prophylaxis should be started at once. And, to prevent recurrence, mosquito net should be used while sleeping, and incomplete closure of both the nasal cavity (modified Young's operation) should be carried out.
