RESUMO
Subjective Benign Paroxysmal Positional Vertigo (S-BPPV) is an atypical form of BPPV, its treatment is not well characterized and is not well known among otolaryngologists. The main aim of this study was to estimate the short-term efficacy of Epley maneuver as treatment for S-BPPV. This was a prospective study in a secondary care center. We included patients with unilateral S-BPPV demonstrated by negative nystagmus on Dix-Hallpike Maneuver (DHM) but with unilateral vestibular symptoms (dizziness or vertigo). Epley maneuver to the affected side was performed. Patients underwent Dizziness Handicap Inventory (DHI) and at 1-week follow-up, DHI and DHM were repeated. Outcome measures were resolution of symptoms during DHM and improvement of DHI scores. Patients were divided into resolved and unresolved groups according to the absence or presence of symptoms during the 1 week DHM. Wilcoxon-Mann-Whitney and Kruskal-Wallis tests were used, quantitative values were reported as mean and standard deviation. The results included thirteen participants, 12 females and 1 male, mean age 53.31 years (SD ± 15.71). Right ear was involved in 46.15% and left in 53.84%. A total of 46.15% patients (n = 6) had resolution of symptoms. DHI initial score for the resolved group was 34.66 ± 22 and for the unresolved group was 39.71 ± 19.61 (p = 0.568). At 1-week evaluation scores were 19.66 ± 25.05 for the resolved group and 30.28 ± 21.42 for the unresolved group (p = 0.252). DHI improvement was 15.00 ± 23.21 and 9.42 ± 10.17 for each group, respectively (p = 0.943). We concluded the Epley maneuver is an effective short-term treatment for S-BPPV. Half of the patients would need further diagnostic tests.
RESUMO
Background: Chronic otitis media (COM) questionnaire 12 (COMQ-12) is a specific-disease tool that evaluates COM patients.Objective: To validate COMQ-12 in the Mexican Spanish language (COMQ-12-Mx).Materials and methods: Mexican Spanish-speaking healthy volunteers and COM patients who attended a Secondary Care Center from May 2019 to October 2019. The COMQ-12 in Mexican Spanish was obtained by translation and back translation from an English-Spanish translator. All participants completed the COMQ-12-Mx questionnaire. COM patients were included regardless of their COM status. Control group completed the questionnaire twice. Participants were categorized into three groups: group 1 (COM), group 2 (volunteers first test) and group 3 (volunteers retest). Cronbach's alpha was used for internal consistency, Spearman's rank correlation coefficient was used for test-retest reliability and Mann-Whitney U test compared groups.Results: We included 78 Mexican Spanish-speaking participants (COM n = 37, healthy volunteers n = 41), 51 females and 27 males, mean age was 39.67 years (SD ± 18.32). Group 1 COMQ-12-Mx score was 22.108 ± 11.79, group 2 score was 3.561 ± 4.399 (p ≤ .001) and group 3 score was 3.683 ± 4.435. Cronbach's alpha was 0.828 and test-retest reliability achieved a 0.928 outcome.Conclusions: COMQ-12-Mx is a valid and reliable tool to evaluate quality life in Mexican Spanish-speaking patients with COM.
