ABSTRACT
AIMS: Hyposmia and hypogeusia are one of the symptoms of COVID-19. Occurrence and course of these symptoms and their relationship with severity of COVID-19 disease are studied. MATERIALS AND METHODS: This was a prospective cohort study, including consenting adult SARS CoV-2 positive patients of both genders, admitted to a Covid Hospital in Puducherry, India. This questionnaire- based study was conducted for a period 4 months from 1st October 2020 to 31st January 2021, and collected data was analyzed using SPSS version 24.0 software. RESULTS: Out of 639 participants, 412 (64.5%) were males, 227 (35.5%) were females. Total cases of new onset hyposmia were 167 (26.1%), and total patients with new onset hypogeusia were 172 (26.91%). 216 (33.80%) had either hyposmia/hypogeusia. First symptom as hyposmia was noted in 49 (7.67%) patients, and as hypogeusia in 20 (3.13%) patients before development of any other symptoms. 216 (33.80%) patients had either smell or taste disturbance as one of their symptoms. By the end of 5 weeks of illness, 96.41% of hyposmic patients, and 97.67% of hypogeusic patients recovered fully. There was no statistically significant difference between presence or absence of hyposmia/hypogeusia and severity of COVID-19 disease (p value = 0.95). CONCLUSION: The occurrence of hyposmia and hypogeusia among Indian COVID-19 patients is more than 26%. Presence or absence of hyposmia/hypogeusia is not a predictor of severity of COVID-19 disease. More than 96% of the patients fully recovered their sense of smell and taste sensation by the end of 5 weeks.
ABSTRACT
Voice Handicap Index (VHI) is the most commonly used tool to assess the quality of life in voice disordered patients. A validated Tamil language version of VHI is not developed yet. Hence, this study was undertaken to translate and validate the Voice Handicap Index in Tamil language, which can potentially benefit Tamil speaking patients with voice disorders. This was a translation and tool validation study done at a tertiary care teaching hospital using an analytical, follow up design according to WHO guidelines. Dysphonic (Group A) and Normal (Group B) respondents were purposively invited to fill a self administered VHI-Tamil questionnaire. The content validity, response process validity, internal consistency and clinical validity of the questionnaire was calculated using appropriate statistical analysis methods using SPSS version 24.0 software. Out of 117 respondents, 61 respondents were dysphonic (Group A) and 56 respondents were normal (Group B). Overall index for content validation was over 0.84, and response process validation was 1.00 in all domains. Overall internal consistency was excellent, with Cronbach's alpha of 0.993. Excellent test-retest reliability was identified using the Spearman rank correlation coefficient (r = 0.96; p-value < 0.001). For clinical validity, a statistically significant difference between the dysphonic and the normal groups, for the overall VHI-Tamil scores and each of the three domain scores was noted. VHI-Tamil was found to be reliable and valid for assessing the quality of life in patients with voice disorders. It can be recommended for future use among Tamil speaking population.
