ABSTRACT
INTRODUCTION: Olfactory symptoms have been reported as particular in COVID-19 patients. OBJECTIVE: To synthesize and analyze the existing evidence on the monitoring loss of sense of smell and taste in COVID-19 patients, and for how long symptoms persist after the virus is no longer active in the organism. METHODS: A search was implemented in PubMed, Embase, Scopus, Science Direct, and Web of Science databases. This systematic review and meta-analysis were conducted according to PRISMA, and the risk of bias was assessed through the Newcastle-Ottawa Scale. The review protocol is registered in PROSPERO. RESULTS: Our systematic review included data from 14 articles with a total of 2143 participants. The most reported sensory symptom of COVID-19 was anosmia, which was detected in 1499 patients, being the only symptom to appear in all studies. Ageusia was detected in 595 patients, dysgeusia in 514 patients, and hyposmia in 209 patients. The studies provided the number of 729 patients with sensory symptoms during the acute COVID-19 infection of 15 days, and 1020 patients with lasting sensory symptoms, presenting sensory dysfunctions after the average latent period of 15 days of the acute COVID-19 infection. CONCLUSION: Evidence points to the loss or dysfunction of taste and smell as one of the symptoms of COVID-19 persisting for an average time of 15 days, with 44% of COVID-19 patients with persistent symptoms for more than 15 days. Nevertheless, most studies do not perform a follow-up with those patients. Therefore, further research on sensory symptoms and their follow-up is required.
INTRODUÇÃO: Sintomas olfativos foram relatados como específicos em pacientes com COVID-19. OBJETIVO: Sintetizar e analisar as evidências existentes sobre o monitoramento da perda de olfato e paladar em pacientes com COVID-19 e por quanto tempo os sintomas persistem. MÉTODOS: Foi realizada uma busca nas bases de dados PubMed, Embase, Scopus, Science Direct e Web of Science. Esta revisão sistemática e metanálise foi realizada de acordo com o PRISMA, e o risco de viés foi avaliado por meio da Escala de Newcastle-Ottawa. O protocolo de revisão está registrado no PROSPERO. RESULTADOS: Nossa revisão sistemática incluiu dados de 14 artigos com um total de 2143 participantes. O sintoma sensorial mais comumente relatado de COVID-19 foi anosmia, detectado em 1.499 pacientes, sendo o único sintoma a aparecer em todos os estudos. Ageusia foi detectada em 595 pacientes, disgeusia em 514 pacientes e hiposmia em 209 pacientes. Os estudos forneceram o número de 729 pacientes com sintomas sensoriais por 15 dias durante a infecção aguda por COVID-19 e 1020 pacientes com sintomas sensoriais duradouros, apresentando disfunções sensoriais após o período latente médio de 15 dias da infecção aguda por COVID-19. CONCLUSÃO: Evidências apontam a perda ou disfunção do paladar e olfato como um dos sintomas da COVID-19 persistindo por um tempo médio de 15 dias, com 44% dos pacientes com COVID-19 com sintomas persistentes por mais de 15 dias. No entanto, a maioria dos estudos não realiza acompanhamento desses pacientes. Portanto, mais pesquisas sobre sintomas sensoriais e seu acompanhamento são necessárias.

Abstract Introduction Some common symptoms of Coronavirus disease 2019 (COVID-19) are fever, cough, and shortness of breath. But ear, nose, and throat (ENT) manifestations such as loss of smell and taste are also very common. Objectives To compare the general and otorhinolaryngological manifestations of COVID-19 and to compare the treatments given and mortality rate during its two waves. Methods This retrospective study was conducted on severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) cases in a tertiary care teaching hospital. Six hundred patients were included in the 1st wave sample and 516 were in the 2nd wave sample. The data collected included demographics, comorbidities, general, and ENT symptoms, need for ventilatory support, oxygen therapy, and mortality for both the waves. Results Fever, malaise, and myalgia were more frequently presented in the first wave than in the second, whereas shortness of breath was more common in the second wave. In the second wave, a significant increase in anosmia cases was reported, whereas sore throat, nasal obstruction, dysphagia, nasal discharge, and sneezing were significantly reduced compared with the first wave (p < 0.001). The case fatality rate increased from 11.33 to 21.55% (p < 0.001) from the 1st to the 2nd wave. The patients who died in the second wave were younger than those in the first wave. Two doses of vaccination showed protection from the death over those not vaccinated and those who only received one dose (p < 0.05). Conclusion Ear, nose, and throat (ENT) manifestations are very common along with the general symptoms. As anosmia and dysgeusia are early presenting symptoms in COVID-19 patients, all physicians should screen patients for ENT symptoms.
ABSTRACT
Abstract Background Parkinson's disease (PD) causes motor and non-motor symptoms such as hyposmia, which is evaluated through olfactory tests in the clinical practice. Objective To assess the feasibility of using the modified Connecticut Chemosensory Clinical Research Center (mCCCRC) olfactory test and to compare its performance with the Sniffin' Sticks-12 (SS-12, Burghart Messtechnik GmbH, Wedel, Germany) test. Methods A transversal case-control study in which the patients were divided into the PD group (PDG) and the control group (CG). The cost and difficulty in handling substances to produce the mCCCRC test kits were evaluated. Sociodemographic characteristics, smoking habits, past coronavirus disease 2019 (COVID-19) infections, self-perception of odor sense, and cognition through the Montreal Cognitive Assessment (MoCA) were also evaluated. The PDG was scored by part III of the Unified Parkinson's Disease Rating Scale (UPDRS-III) and the Hoehn and Yahr Scale (H&Y) scale. Correlations were assessed through the Spearman rank correlation coefficient test (ρ, or rho). Results The mCCCRC test was easily manufactured and handled at a cost ten times lower compared with the SS-12. The groups (PDG: n= 34; CG: n= 38) were similar in terms of age, sex, level of schooling, smoking habits, and history of COVID-19. The tests results showed moderate correlation (rho = 0.65; p< 0.0001). The CG presented better cognitive performance and scored better in both tests (p< 0.0001). There was a tendency for a negative correlation with age, but good correlation with the MoCA (p= 0.0029). The results of the PDG group showed no correlation with olfactory results and motor performance or disease duration. The self-perception of hyposmia was low in both groups. Conclusion The mCCCRC is an easy-to-apply and inexpensive method that demonstrated a similar performance to that of the SS-12 in evaluating olfaction in PD patients and healthy controls.
Resumo Antecedentes A doença de Parkinson (DP) cursa com sintomas motores e não motores como a hiposmia, que é avaliada por diferentes testes olfativos na prática clínica. Objetivo Avaliar a viabilidade do teste olfatório Connecticut Chemosensory Clinical Research Center modificado (mCCCRC) e compará-la à do teste Sniffin' Sticks-12 (SS-12, Burghart Messtechnik GmbH, Wedel, Alemanha). Métodos Estudo transversal de caso-controle em que os pacientes foram divididos no grupo DP (GDP) e no grupo controle (GC). O custo e as dificuldades no manuseio das substâncias necessárias para a produção dos kits do teste mCCCRC foram avaliados. Características sociodemográficas, tabagismo, histórico de infecção por doença do coronavírus 2019 (coronavírus disease 2019, COVID-19, em inglês), autopercepção do olfato e cognição pelo Montreal Cognitive Assessment (MoCA) também foram avaliados. O GDP foi avaliado pela parte III da Unified Parkinson's Disease Rating Scale (UPDRS-III) e pela escala de Hoehn and Yahr (H&Y). As correlações utilizaram o teste do coeficiente de correlação de postos de Spearman (ρ, ou rho). Resultados O mCCCRC foi facilmente poroduzido e manipulado com custo dez vezes inferior ao do SS-12. Os grupos (GDP: n= 34; GC: n= 38) eram similares em termos de idade, sexo, escolaridade, tabagismo e histórico de COVID-19. Os resultados obtidos em ambos os testes mostraram excelente correlação (rho = 0.65; p< 0.0001). O GC teve um desempenho cognitivo melhor e pontuou melhor nos dois testes (p< 0.0001). Houve uma tendência a uma correlação negativa com a idade, mas boa correlação com a pontuação no MoCA (p= 0.0029). Os resultados olfativos do GDP não mostraram correlação com desempenho motor ou duração da doença. A autopercepção de hiposmia foi baixa em ambos os grupos. Conclusão O mCCCRC é um teste de fácil aplicação, baixo custo, e apresentou um desempenho semelhante ao do SS-12 na avaliação olfativa de pacientes com DP e controles saudáveis.
ABSTRACT
Os distúrbios do olfato (DO) impactam de forma significativa na qualidade de vida dos indivíduos, e o conhecimento teórico a respeito do assunto deve ser de domínio dos alergologistas e imunologistas clínicos, possibilitando, assim, o seu diagnóstico e implementação de intervenções. Suas causas podem ser variadas, entre elas estão: rinite alérgica, rinossinusite crônica com ou sem pólipos, infecções de vias aéreas superiores, exposição a substâncias químicas, doenças neurológicas, drogas, traumas e o próprio envelhecimento. O olfato pode ser avaliado e mensurado através de testes com metodologias diferentes, cujo objetivo é avaliar parâmetros como a identificação de odores, limiar e discriminação olfativa. Esses testes são de fundamental importância para caracterizar objetivamente a queixa do paciente, como também avaliar o olfato antes e após determinada aplicação terapêutica. O tratamento das desordens olfativas é baseado em sua etiologia, portanto determinar a sua causa é indispensável para uma melhor eficácia no manejo. Entre as principais opções estão os corticoides tópicos, com impacto significativo nos pacientes com doença sinusal associada, treinamento olfatório e outras intervenções como ômega 3, vitamina A intranasal, e terapias que ainda requerem mais estudos.
Olfactory dysfunction significantly impacts quality of life, and allergists and clinical immunologists must be informed about it for diagnostic and interventional purposes. The causes are varied: allergic rhinitis, chronic rhinosinusitis with or without polyps, upper airway infections, exposure to chemicals, neurological diseases, drugs, trauma, and aging itself. Olfactory function can be evaluated and measured by several tests that use different methodologies to evaluate and identify odors, olfactory threshold, and olfactory discrimination. These tests are fundamental for objectively characterizing patient complaints and evaluating olfactory function before and after therapeutic interventions. Olfactory disorders are treated according to their etiology, so determining their cause is a major factor in treatment efficacy. The main options include topical corticosteroids, which have a significant impact on patients with sinus disease, olfactory training, other therapies (such as omega 3 and intranasal vitamin A), in addition to therapies that require further research.

Introducción: existe escasa evidencia de la prevalencia de disfunciones olfatorias, como la parosmia post infección de COVID-19, en población chilena y a la vez como esta afecta la alimentación y nutrición de los sujetos que la padecen. Objetivo: describir los cambios en la alimentación causados por la parosmia secundaria a COVID-19 según las características sociodemográficas en población adulta residente en Chile durante el año 2021. Métodos: estudio cuantitativo transversal descriptivo con una muestra de 542 participantes, se aplicó un cuestionario de autoría propia, en el que se consideran datos sociodemográficos, factores condicionantes en la alimentación, cambios en la alimentación y técnicas culinarias. Resultados: se reportó una prevalencia de parosmia del 65%, afectando principalmente a las mujeres con un 85,8%, con un promedio de edad de 32 ± 9 años y 33 ± 9 años para mujeres y hombres respectivamente. Los principales cambios alimentarios fueron una disminución de la ingesta de carnes, huevos y comida rápida y un aumento del consumo de verduras, además se observó una menor diversificación en las técnicas culinarias utilizadas para la cocción de los alimentos. Conclusión: se reportaron cambios importantes en la alimentación de los sujetos con parosmia, lo que pone en evidencia la necesidad de investigar como esto afecta el estado nutricional y calidad de vida de los sujetos que la padecen.
Introduction: there is little evidence of the prevalence of olfactory dysfunctions, such as post-COVID-19 infection parosmia, in the Chilean population and at the same time how it affects the food and nutrition of the subjects who suffer from it. Objective: to describe the changes in the diet caused by parosmia secondary to COVID-19 according to sociodemographic characteristics in the adult population residing in Chile during the year 2021. Methods: descriptive cross-sectional quantitative study with a sample of 542 participants, a questionnaire of own authorship, in which sociodemographic data, conditioning factors in food, changes in food, and culinary techniques are considered. Results: a prevalence of parosmia of 65% was reported, mainly affecting women at 85.8%, with an average age of 32 and 33 years for women and men, respectively. The main dietary changes were a decrease in the intake of meat, eggs, and fast food and an increase in the consumption of vegetables, in addition, less diversification was observed in the culinary techniques used for cooking food. Conclusion: important changes were reported in the diet of subjects with parosmia, which highlights the need to investigate how this affects the nutritional status and quality of life of subjects who suffer from it.
ABSTRACT
Abstract Introduction Anosmia is one of the common symptoms of COVID-19, the link between severity of chest infection and anosmia was investigated by few studies. Objectives To find an association between anosmia and severity of chest infection. Methods An analysis of patients admitted to isolation hospital of our university with confirmed polymerase chain reaction positive testing for COVID-19, between March 2021 until September 2021. We called all patients who reported anosmia during their time of illness and asked them about anosmia. We examined their chest CT. A statistical analysis was done. Results A total of 140 patients completed the study; 65% were female and 56.4% had complete anosmia. Anosmia was significantly associated with loss of taste. Smell returned in 92.5% of anosmic patients. Duration of smell loss was ~ 2 weeks in 40.5%. The most common symptoms associated with anosmia were running nose, sore throat, fever, and cough. Loss of smell was significantly associated with mild chest disease. 73.4% of anosmic patients had mild chest infection, 21.5% of them had moderate infection, and 5.1% had severe chest infection. Conclusion The pattern of anosmia in COVID-19 patients has some common similarities in general; the way it starts, the associated symptoms, the time until smell returns and, the most important, the severity of chest infection. As anosmia is significantly associated with mild chest infection. the presence of anosmia could be an independent predictor of good COVID-19 outcome as reflected by a lower disease severity and less frequent ICU admissions.
ABSTRACT
Post Covid complication occurs in individuals with a history of con?rmed covid-19 infection, that develop within 3months of onset of COVID-19 illness, last for at least 2months and cannot be explained by alternative diagnosis. We aim to estimate the magnitude of post covid complications and its association with risk factors. A follow up study was conducted among 250 COVID19 positive patients from July 2021 to Jan2022. These patients were interviewed telephonically at 3rd month & 6th month after recovery. Majority of post COVID symptoms identified were fatigue (29.6%), anosmia (26.8%) & ageusia (15.2%). At least one of these symptoms was present in 67.6% and 28% patients at 3rd and 6th month post infection respectively. Other clinical features included insomnia (8%), skin rashes (7.6%) and mood disorders (4%). Systemic involvement was seen in 1.2% as new onset hypertension. No significant gender difference was identified in any of the symptoms (?2=0.24, p=0.6). Risk factors associated in developing long COVID-19 were high BMI[RR=1.2], age >60yrs [RR=1.3], poor vaccination status [RR=1.45]and long duration of illness (>14 days) [RR=1.4]. 4 deaths (1.6%) were reported among 8.8% hospitalized patients having severe comorbidities (e.g. Coronary artery disease). Nearly 2/3rd patients were having one or the other symptoms at the end of the 3rd month and 1/4th at the end of 6th months. Also, death during the post COVID period, strongly suggests continuous follow up visits for high risk patients and spreading public awareness to seek health care facilities for follow up.
ABSTRACT
@#Introduction: The clinical signs of COVID-19 include ageusia and anosmia. Anosmia and ageusia haven’t been evaluated as prognostic factors in any prior studies, though. Therefore, the purpose of this review is to assess the effectiveness of ageusia and anosmia as prognostic indicators in COVID-19 patients. Methods: Literature was collected from various databases systematically using the PRISMA until May 25th,2022. The screening process was performed based on inclusion and exclusion criteria, before being analyzed qualitatively. The risk of bias was assessed using Newcastle-Ottawa Quality Assessment Scale converted by AHRQ. Results: Anosmia and ageusia could be used as the indicator for the good prognostic associated with lower mortality, milder trajectory rate, ICU, and hospital admission risk, and shorter length of stay. Anosmia and ageusia have shown high prevalence to predict a prognosis for the COVID-19 infection. Although COVID-19 prognosis also depends on the other lying conditions, patients with anosmia or ageusia had a lower mortality risk due to the lower body mechanism and cell inflammation mechanism toward the viral load that may not lead to the maladaptive cytokine release in response to infection generally called as a cytokine storm. Conclusion: In COVID-19 patients, anosmia and ageusia have been shown to be indicators of a favorable prognosis due to lower disease severity, mortality, risk of ICU and hospital admission, and shorter duration of stay. Therefore, in order to determine the prognosis, it is important to assess the clinical symptoms of the patients.
ABSTRACT
Abstract Background The neurological manifestations in COVID-19 adversely impact acute illness and post-disease quality of life. Limited data exist regarding the association of neurological symptoms and comorbid individuals. Objective To assess neurological symptoms in hospitalized patients with acute COVID-19 and multicomorbidities. Methods Between June 2020 and July 2020, inpatients aged 18 or older, with laboratory-confirmed COVID-19, admitted to the Hospital São Paulo (Federal University of São Paulo), a tertiary referral center for high complexity cases, were questioned about neurological symptoms. The Composite Autonomic Symptom Score 31 (COMPASS-31) questionnaire was used. The data were analyzed as a whole and whether subjective olfactory dysfunction was present or not. Results The mean age of the sample was 55 ± 15.12 years, and 58 patients were male. The neurological symptoms were mostly xerostomia (71%), ageusia/hypogeusia (50%), orthostatic intolerance (49%), anosmia/hyposmia (44%), myalgia (31%), dizziness (24%), xerophthalmia (20%), impaired consciousness (18%), and headache (16%). Furthermore, 91% of the patients had a premorbidity. The 44 patients with subjective olfactory dysfunction were more likely to have hypertension, diabetes, weakness, shortness of breath, ageusia/hypogeusia, dizziness, orthostatic intolerance, and xerophthalmia. The COMPASS-31 score was higher than that of previously published controls (14.85 ± 12.06 vs. 8.9 ± 8.7). The frequency of orthostatic intolerance was 49% in sample and 63.6% in those with subjective olfactory dysfunction (2.9-fold higher risk compared to those without). Conclusion A total of 80% of inpatients with multimorbidity and acute COVID-19 had neurological symptoms. Chemical sense and autonomic symptoms stood out. Orthostatic intolerance occurred in around two-thirds of the patients with anosmia/hyposmia. Hypertension and diabetes were common, mainly in those with anosmia/hyposmia.
Resumo Antecedentes As manifestações neurológicas na COVID-19 impactam adversamente na enfermidade aguda e na qualidade de vida após a doença. Dados limitados existem em relação a associação de sintomas neurológicos e indivíduos com comorbidades. Objetivo Avaliar os sintomas neurológicos em pacientes de hospitalizados com COVID-19 aguda e múltiplas comorbidades. Métodos Entre junho e julho de 2020, pacientes de hospitais com idade 18 anos ou acima e COVID-19 laboratorialmente confirmada, admitidos no Hospital São Paulo (Universidade Federal de São Paulo), um centro de referência terciário para casos de alta complexidade, foram perguntados sobre sintomas neurológicos. O questionário Pontuação composta de sintoma autonômico (COMPASS-31) foi usado. Os dados foram analisados no geral e se a disfunção olfatória subjetiva estava presente ou não. Resultados A média de idade da amostra foi 55 ± 15.12 anos. 58 pacientes eram homens. Os sintomas neurológicos foram principalmente xerostomia (71%), ageusia/hipogeusia (50%), intolerância ortostática (49%), anosmia/hiposmia (44%), mialgia (31%), tontura (24%), xeroftalmia (20%), comprometimento na consciência (18%) e cefaleia (16%). Além disso, 91 % dos pacientes tinham uma pré-morbidade. Os 44 pacientes com disfunção olfatória tinham maior chance de ter hipertensão, diabetes, fraqueza, falta de ar, ageusia/hipogeusia, tontura, intolerância ortostática e xeroftalmia. A pontuação do COMPASS-31 foi maior do que a de controles previamente publicados (14,85 ± 12,06 vs. 8,9 ± 8,7). A frequência de intolerância ortostática foi 49% na amostra e 63,6% naqueles com disfunção olfatória subjetiva (risco 2.9 vezes maior comparado com os sem). Conclusão Um total de 80% dos pacientes hospitalizados com múltiplas morbidades e COVID-19 aguda tinham sintomas neurológicos. Os sintomas do sentido químico e autonômicos se destacaram. A intolerância ortostática ocorreu em cerca de dois terços dos pacientes com anosmia/hiposmia. A hipertensão e o diabetes foram comuns, principalmente naqueles com anosmia/hiposmia.
ABSTRACT
A infecção humana causada pelo vírus SARS-CoV-2 (COVID-19), diagnosticada como pneumonia de causa desconhecida originalmente na cidade de Wuhan (China), foi considerada como pandemia pela Organização Mundial da Saúde. Com a inexistência inicial de uma vacina para proteção dos sadios, foi adotada a estratégia de isolamento social e tratamento com medidas de suporte geral e/ou avançado. Neste contexto, coube investigar a contribuição da terapêutica homeopática no enfrentamento da doença, notadamente no alívio dos sintomas desconfortáveis por ela provocados em sua fase inicial, com acompanhamento e registro dos resultados obtidos pelos médicos homeopatas. MÉTODO: Este estudo coletou, durante o período de maio a setembro de 2020 (após aprovação pelo CEP), informações de pacientes diagnosticados com a doença, tratados por médicos homeopatas com medicamentos homeopáticos escolhidos de acordo com a sintomatologia apresentada pelo paciente. Foram avaliados os efeitos no estado de saúde do paciente, por meio de escores e escalas clínicas, bem como aspectos relacionados à segurança do medicamento, variação na duração da doença e medicamentos mais associados a eventuais sucessos terapêuticos. Questionário padronizado e específico para a COVID-19 foi elaborado e e aplicado para preenchimento dos médicos colaboradores do estudo durante o acompanhamento dos pacientes. Os dados foram armazenados em planilhas eletrônicas e analisados com técnicas estatísticas descritivas e inferenciais. Os pacientes selecionados eram colaboradores do Hospital Santo Antônio - Obras Sociais Irmã Dulce (OSID) e foram submetidos a uma avaliação preliminar presencial no ambulatório de Otorrinolaringologia deste hospital. As consultas homeopáticas foram realizadas por plataforma de Telemedicina para seguimento e acompanhamento do caso. Foram avaliados 116 colaboradores, com faixa etária que variou entre 21 e 66 anos, sendo a média de idade 38 anos; destes, 84 (72%) eram do gênero feminino e 32 (16%) gênero masculino; 53 pacientes (70% dos colaboradores atendidos) eram profissionais da saúde (médicos, enfermeiros e técnicos de enfermagem); 63 (30%) eram colaboradores de áreas administrativas ou técnicas; 50 pacientes tinham critérios para inclusão no grupo de risco (43%). Quanto ao resultado do RT-PCR: 58 pacientes (50%) tiveram RT-PCR detectado (confirmados); 58 pacientes (50%) tiveram RT-PCR não-detectado - destes, 18 pacientes (31%) apresentaram anosmia em sua evolução. Dos 116 pacientes do critério de inclusão, 77 estavam incluídos na síndrome clássica da COVID19. Destes 77 colaboradores, 3 não usaram o medicamento homeopático (N=74). Os medicamentos homeopáticos mais indicados foram: Arsenicum album (42%); Bryonia (24%), Phosphorus (15%); Gelsemium (15%); Pulsatilla (2%); outros (4%). O Score médio de sintomas antes do tratamento foi 12,27 e após o tratamento foi 0,52 (p < xxxxx). Dos 57 pacientes que tiveram anosmia, houve recuperação total em 43 (75%) dos casos no momento da reavaliação. O tempo médio decorrido entre o uso da medicação homeopática e a recuperação dos sintomas foi de 9 dias. Apenas 3 pacientes (3,9%) necessitaram de internamento hospitalar sem necessidade de intubação, sendo 2 deles pertencentes ao grupo de risco. apesar destes resultados serem parciais (pois ainda existem sujeitos da pesquisa ainda em fase de avaliação), os resultados sugerem que o tratamento homeopático promoveu o restabelecimento do quadro infeccioso sem necessidade de internamento em 97% dos pacientes. A anosmia teve recuperação completa em 75% dos pacientes. Arsenicum album, Bryonia e Phosphorus foram os medicamentos predominantemente eleitos para o tratamento, o que corrobora com outros estudos homeopáticos.
The human infection caused by the SARS-CoV-2 virus (COVID-19), originally diagnosed as pneumonia of unknown cause in the city of Wuhan (China), was considered a pandemic by the World Health Organization. With the initial lack of a vaccine to protect healthy people, the strategy relating to social isolation and treatment with general and/or advanced support measures was adopted. In this context, it was necessary to investigate the contribution of homeopathic therapy in coping with the disease, particularly in terms of relieving the uncomfortable symptoms caused by it in its initial phase, with monitoring and recording of the results obtained by homeopathic physicians. METHOD: This study collected information from patients diagnosed with the disease, treated by homeopathic physicians with homeopathic medications chosen according to the symptoms manifested by the patient, from May to September 2020 (after approval by the REC). The effects on the health conditions of patients were assessed using clinical scores and scales, as well as aspects related to the safety of the medication, variations in the duration of the disease and the medications most associated with any therapeutic successes. A standardized questionnaire specific to COVID-19 was drawn up and filled in by the physicians who collaborated in the study during patient monitoring. The data was stored in electronic spreadsheets and analyzed using descriptive and inferential statistical techniques. The selected patients were employees of Hospital Santo Antônio - Obras Sociais Irmã Dulce (OSID) and underwent a preliminary in-person assessment at the otolaryngology outpatient clinic of this hospital. The homeopathic consultations were carried out via a telemedicine platform to follow-up and monitor the case. A total of 116 employees were assessed, ranging in age from 21 to 66, with the average age being 38; of these, 84 (72%) were females and 32 (16%) males; 53 patients (70% of the employees cared for) were health care professionals (physicians, nurses and nursing technicians); 63 (30%) were employees from administrative or technical areas; 50 patients met the criteria for inclusion in the risk group (43%). As for the RT-PCR result: 58 patients (50%) had RT-PCR detected (confirmed); 58 patients (50%) had RT-PCR not detected - of these, 18 patients (31%) had anosmia during their evolution. Of the 116 patients who met the inclusion criteria, 77 were included in the classic COVID-19 syndrome. Of these 77 collaborators, 3 did not use homeopathic medication (N=74). The most indicated homeopathic medications were: Arsenicum album (42%); Bryonia (24%), Phosphorus (15%); Gelsemium (15%); Pulsatilla (2%); others (4%). The average symptom score before treatment was 12.27 and after treatment was 0.52 (p < xxxxx). Of the 57 patients who had anosmia, there was full recovery in 43 (75%) of the cases at the time of reassessment. The average time elapsed between the use of homeopathic medication and the recovery of symptoms was 9 days. Only 3 patients (3.9%) required hospitalization without the need for intubation, 2 of whom belonged to the risk group. Although these results are partial (as there are still research subjects in the evaluation phase), the results suggest that homeopathic treatment promoted the re-establishment of the infectious condition without the need for hospitalization in 97% of the patients. Anosmia recovered completely in 75% of the patients. Arsenicum album, Bryonia and Phosphorus were the drugs predominantly chosen for treatment, which corroborates other homeopathic studies.

El olfato desempeña una función importante en el desarrollo diario de la vida de las personas. Sus alteraciones pueden ser cualitativas (disosmias, parosmias o fantosmias) y cuantitativas (hiposmia o anosmia). Estas alteraciones pueden deberse por enfermedades rinosinusales, neurodegenerativas o infecciones respiratorias como el resfriado común, la gripe y también el SARS-CoV-2, el agente causal del COVID-19. En relación a esta etiología, su fisiopatología no es del todo clara y la anosmia es poco distinguible clínicamente del resto de las infecciones virales, con una duración variable desde ocho días hasta más de cuatro semanas, en cuyo caso se denomina síndrome pos-COVID-19 o COVID prolongado. Este cuadro se caracteriza por la presencia de síntomas que se desarrollan durante la enfermedad aguda por COVID-19,y que persisten durante más de cuatro semanas, sin explicación por un diagnóstico alternativo. El autor de este artículo realiza una revisión de la literatura médica a partir de un caso clínico con el fin de identificar y resumir la evidencia disponible sobre la terapia de rehabilitación olfatoria.

Sense of smell plays an important role in the daily development of people's lives. Its alterations can be both qualitative (dysosmias, parosmias, or phantosmias) and quantitative (hyposmia or anosmia). These alterations may be due to rhinosi-nusal diseases, neurodegenerative diseases, and respiratory infections such as common cold, influenza, and SARS-CoV-2,causative agent of COVID-19. In relation to this etiology, its pathophysiology is not entirely clear, and anosmia is clinically indistinguishable from the rest of the viral infections, with a variable duration ranging from eight days to more than four weeks, in which case it would be called post COVID- 19 syndrome or prolonged COVID. This condition is characterized by the presence of symptoms that develop during acute COVID-19 illness and persist for more than four weeks without an explanation by an alternative diagnosis.The author of this article carries out a review of the medical literature based on a clinical case in order to identify and summarize the available evidence on olfactory rehabilitation therapy.

SARS-COV-2 is transmitted among human beings by saliva droplets that come in direct contact with the oral cavity, nose, and eyes. Since the mouth is one of the anatomical sites primarily contaminated, oral manifestations have also been reported beyond the serious consequences inherent to progressive respiratory failure. This study aimed to identify oral manifestations possibly related to the infection by COVID-19 in hospitalized patients. A prospective study was carried out with patients diagnosed with COVID-19 in the period between March and June 2021, admitted to the Moderate COVID-19 Care Unit of the Hans Dieter Schmidt Regional Hospital, by applying a form and performing a clinical exam of the oral cavity. Out of all patients (n=45), 33.3% reported both olfactory (anosmia) and taste dysfunction (dysgeusia), with an average duration of 5.9 ±3.0 days. Regarding other oral manifestations evaluated, two patients reported dry and burning mouth and one patient reported a change in taste associated with plaque-like changes in the tongue. No patients presented ulcers or other lesions in the oral cavity. Olfactory and taste dysfunction were symptoms recognized of the novel coronavirus disease (COVID-19). However, the association with other oral manifestations is still controversy. Unfortunately, dentistry professionals are still not part of most teams in the hospital environment, mostly because of the lack of prioritization of dental care. Working with a multidisciplinary team may avoid possible systemic complications due to poor dental care.
Sars-COV-2 é transmitida entre os seres humanos por gotículas de saliva que entram em contato direto com a cavidade oral, nariz e olhos. Uma vez que a boca é um dos sítios anatômicos principalmente contaminados, as manifestações orais também foram relatadas para além das graves consequências inerentes à insuficiência respiratória progressiva. Este estudo teve como objetivo identificar manifestações orais possivelmente relacionadas à infecção por Covid-19 em pacientes hospitalizados. Foi realizado um estudo prospetivo com pacientes diagnosticados com Covid-19 no período entre março e junho de 2021, internados na Unidade de Atendimento Moderado contra a Covid-19 do Hospital Regional Hans Dieter Schmidt, aplicando um formulário e realizando um exame clínico da cavidade oral. De todos os pacientes (n=45), 33,3% relataram disfunção olfativa (anosmia) e gustativa (disgeusia), com duração média de 5,9 ±3,0 dias. Em relação a outras manifestações orais avaliadas, dois pacientes relataram boca seca e ardente e um paciente relatou alteração no paladar associada a alterações semelhantes a placas na língua. Nenhum paciente apresentou úlceras ou outras lesões na cavidade oral. Disfunção olfativa e gustativa foram sintomas reconhecidos do novo coronavírus (Covid-19). No entanto, a associação com outras manifestações orais ainda é controversa. Infelizmente, os profissionais de odontologia ainda não fazem parte da maioria das equipes do ambiente hospitalar, principalmente por causa da falta de priorização dos cuidados odontológicos. Trabalhar com uma equipe multidisciplinar pode evitar possíveis complicações sistêmicas devido a cuidados odontológicos deficientes.

Dado que la boca es uno de los sitios anatómicos principalmente contaminados, también se han informado manifestaciones orales más allá de las consecuencias graves inherentes a la insuficiencia respiratoria progresiva. El objetivo de este estudio fue identificar las manifestaciones bucales posiblemente relacionadas con la infección por COVID-19 en pacientes hospitalizados. Se realizó un estudio prospectivo con pacientes diagnosticados de COVID-19 en el periodo comprendido entre marzo y junio de 2021, ingresados en la Unidad de Cuidados Moderados de COVID-19 del Hospital Regional Hans Dieter Schmidt, mediante la aplicación de un formulario y la realización de un examen clínico de la cavidad oral. De todos los pacientes (n=45), el 33,3% notificó tanto disfunción olfativa (anosmia) como gustativa (disgeusia), con una duración media de 5,9 ±3,0 días. En cuanto a las demás manifestaciones orales evaluadas, dos pacientes notificaron sequedad y ardor de boca y un paciente notificó un cambio en el gusto asociado a cambios en la lengua en forma de placa. Ningún paciente presentó úlceras u otras lesiones en la cavidad oral. La disfunción olfativa y gustativa fueron síntomas reconocidos de la nueva enfermedad por coronavirus (COVID-19). Sin embargo, la asociación con otras manifestaciones orales es aún controvertida. Desafortunadamente, los profesionales de la odontología todavía no son parte de la mayoría de los equipos en el entorno hospitalario, principalmente debido a la falta de priorización de la atención odontológica.

Abstract Introduction Quality of life is closely linked to retronasal olfactory function. Familiarity with odors vary, so tests need validation. Testing can be time-consuming, so a quick test and a thorough test are needed for clinical and research settings. Objectives The objectives of this study were to validate the original retronasal powder olfactory test in a Danish population and to develop a novel quick retronasal test for easy application. Methods Ninety-seven participants were included in the study, 59 healthy controls and 38 patients with olfactory impairment. The retronasal test was modified by substituting unfamiliar odors and descriptors and validated with a criterion of correct identification rate of 50% in the original test and 90% in the quick test. Items with over 90% correct identification rate in the modified original test were included in the quick test, resulting in a 10-item test. Results The modified retronasal olfactory test achieved good test characteristics, with a 10th percentile cut-off value of 13: sensitivity was 88.9%, specificity 83.0%, positive predictive value 78%, negative predictive value 91.7%, and the receiver operating characteristics area under the curve (ROC-AUC) was 0.86. The quick test achieved acceptable test characteristics, with a 10th percentile cut-off value of 8.2: sensitivity was 72.2%, specificity 90.6%, positive predictive value 83.9%, negative predictive value was 82.8%, and ROC-AUC 0.81. Conclusion Validation of both tests demonstrated satisfactory accuracy. We recommend the quick test for screening purposes, and the modified original version for a thorough evaluation. The tests are easily implemented as they are easy to understand and very affordable.
ABSTRACT
Abstract Introduction SARS-CoV-2 is the pathogen of COVID-19. The virus is composed of the spike, membrane and envelope. On physiological smell, odoriferous substances bind to proteins secreted by sustentacular cells in order to be processed by olfactory receptor neurons. Olfactory disorder is one of the main manifestations of COVID-19, however, research is still required to clarify the mechanism involved in SARS-CoV-2 induced anosmia. Objective This article aims to analyze current scientific evidence intended to elucidate the pathophysiological relationship between COVID-19 and the cause of olfactory disorders. Methods Pubmed, Embase, Scopus and ScienceDirect were used to compose this article. The research was conducted on November 24th, 2020. Original articles with experimental studies in human, animal and in vitro, short communications, viewpoint, published in the English language and between 2019 and 2020 were included, all related to the pathophysiological relationship between olfactory disorders and COVID-19 infection. Results Both human cell receptors ACE2 and TMPRSS2 are essential for the SARS-CoV-2 entrance. These receptors are mostly present in the olfactory epithelium cells, therefore, the main hypothesis is that anosmia is caused due to damage to non-neuronal cells which, thereafter, affects the normal olfactory metabolism. Furthermore, magnetic resonance imaging studies exhibit a relationship between a reduction on the neuronal epithelium and the olfactory bulb atrophy. Damage to non-neuronal cells explains the average recovery lasting a few weeks. This injury can be exacerbated by an aggressive immune response, which leads to damage to neuronal cells and stem cells inducing a persistent anosmia. Conductive anosmia is not sufficient to explain most cases of COVID-19 induced anosmia. Conclusion Olfactory disorders such as anosmia and hyposmia can be caused by COVID-19, the main mechanism is associated with olfactory epithelium damage, targeting predominantly non-neuronal cells. However, neuronal cells can also be affected, worsening the condition of olfactory loss.
Resumo Introdução SARS‐CoV‐2 é o patógeno da Covid‐19. O vírus é composto pela proteína spike (espigão), a membrana e o envelope. No olfato fisiológico, as substâncias odoríferas se ligam a proteínas secretadas pelas células sustentaculares para serem processadas pelos neurônios receptores olfativos. O distúrbio olfativo é uma das principais manifestações da Covid‐19; entretanto, pesquisas ainda são necessárias para esclarecer o mecanismo envolvido na anosmia induzida pela SARS‐CoV‐2. Objetivos Este artigo tem como objetivo analisar as evidências científicas atuais destinadas a elucidar a relação fisiopatológica entre a Covid‐19 e a causa dos distúrbios olfativos. Método As bases de dados Pubmed, Embase, Scopus e ScienceDirect foram usadas para compor este artigo. A pesquisa foi feita em 24 de novembro de 2020. Foram incluídos artigos originais com estudos experimentais em seres humanos, animais e estudos in vitro, comunicações breves, pontos de vista, publicados na língua inglesa e entre 2019 e 2020, todos relacionados à relação fisiopatológica entre distúrbios olfativos e infecção por Covid‐19. Resultados Ambos os receptores de células humanas ACE2 e TMPRSS2 são essenciais para a penetração do SARS‐CoV‐2. Esses receptores estão presentes principalmente nas células do epitélio olfativo; portanto, a principal hipótese é que a anosmia é causada por lesão de células não neuronais que, a partir daí, afeta o metabolismo olfativo normal. Além disso, estudos de ressonância magnética mostram uma relação entre a redução do epitélio neuronal e a atrofia do bulbo olfatório. Danos às células não neuronais explicam o tempo médio de recuperação, que demora algumas semanas. Essa lesão pode ser exacerbada por uma resposta imune agressiva, que leva a danos às células neuronais e células‐tronco, induz uma anosmia persistente. A anosmia condutiva não é suficiente para explicar a maioria dos casos de anosmia induzida por Covid‐19. Conclusão Distúrbios olfativos como anosmia e hiposmia podem ser causados pela Covid‐19 e o principal mecanismo está associado à lesão do epitélio olfativo, tem como alvo células predominantemente não neuronais. Porém, células neuronais também podem ser afetadas, o que piora o quadro de perda olfativa.
ABSTRACT
Abstract Background Hyposmia is one of the most common, as well as the first nonmotor condition in Parkinson disease (PD). The sniffin sticks test (SST) evaluates three different aspects of olfactory function: threshold (T), discrimination (D), and identification (I). The sum of the scores of these three subtests produce a global score of olfaction, the Threshold-Discrimination-Identification (TDI) score. Objective The aim of this study was to investigate if the TDI score or one of its subtests is better to discriminate PD patients from controls. Methods We recruited 27 PD patients and 17 healthy age-matched controls (HC) who were evaluated through a clinical interview, the Montreal Cognitive Assessment and Movement Disorders Society - Unified Parkinson Disease Rating Scale. The olfaction was assessed using the complete SST. Results The performance of PD patients on the olfactory test was significantly worse when compared with the HC (T: 3.0 vs. 6.5, p < 0.001; D: 8.1 vs. 11.2, p <0.001; I: 7.3 vs. 11.7, p < 0.001; TDI: 18.8 vs. 29.9, p < 0.001). The prevalence of olfaction impairment in our study (PD: 100%, and HC: 56%) was greater than that found in the literature. Cognition influenced the performance on TDI. The olfactory subtests were impaired proportionally between patients and controls. Furthermore, D and I were correlated, but only in PD patients. The TDI showed a tendency to better discriminate PD patients from HC, when compared with its subtests. Conclusions Although the complete olfactory evaluation is time consuming, it seems to be a superior tool to identify olfaction impairment in PD patients, when compared with the isolated subtests.
Resumo Antecendentes Hiposmia é um dos sintomas mais comuns da doença de Parkinson (DP), além de ser um de seus primeiros sintomas não-motores. O Sniffin Sticks Test avalia três diferentes aspectos da função olfatória: limiar (L), discriminação (D) e identificação (I). A soma dos escores desses três subtestes produz um escore global do olfato, o Threshold-Discrimination-Identification (TDI). Objetivo O objetivo deste estudo foi investigar se oTDI ou um de seus subtestes seria melhor em discriminar pacientes com DP de controles saudáveis. Métodos Foram recrutados 27 pacientes com DP e 17 controles saudáveis de mesma faixa etária, que foram avaliados através de uma entrevista clínica, a Montreal Cognitive Assessment e Movement Disorders Society - Unified Parkinson Disease Rating Scale. O olfato foi examinado através da bateria completa do Sniffin Sticks Test (SST). Resultados Os pacientes com DP tiveram pior performance no teste olfatório quando comparados com os controles (L: 3,0 vs. 6,5; p < 0,001; D: 8,1 vs. 11,2; p <0,001; I: 7,3 vs. 11,7; p <0,001; TDI: 18,8 vs. 29,9; p < 0,001). A prevalência de comprometimento olfatório no nosso estudo (DP: 100%, e controles: 56%) foi maior do que a reportada na literatura. A cognição influenciou a performance no TDI. Os subtestes olfatórios foram afetados proporcionalmente entre pacientes e controles. Além disso, D e I se correlacionaram, mas apenas em pacientes de DP. O TDI mostrou uma tendência em melhor discriminar pacientes de DP dos controles, quando comparado com os seus subtestes. Conclusões Embora a avaliação olfatória completa consuma tempo, ela parece ser superior aos subtestes isolados para identificar comprometimento olfatório em pacientes com DP.
ABSTRACT
Contexto Los pacientes en hemodiálisis son una población susceptible para la enfermedad causada por el SARS-CoV-2, enfermedad por el coronavirus 2019 (COVID-19), siendo el diagnóstico temprano una necesidad urgente por considerarse una población de riesgo por presentar cuadros severos y graves. Objetivo Estimar si la anosmia de inicio súbito permite una detección temprana de la infección por COVID-19, en pacientes de hemodiálisis sin síntomas clásicos (que no presentaron malestar general, síntomas respiratorios o gastrointestinales al inicio de la enfermedad). Metodología Se realizó un estudio de prueba diagnóstica durante los meses de septiembre y octubre del 2020 en tres unidades de hemodiálisis en Colombia. Fueron incluidos pacientes adultos, sin síntomas clásicos para COVID-19. Se excluyó a los pacientes con infección previa por COVID-19 o con antecedentes de alteración del olfato. Se recolectaron datos demográficos, clínicos y de laboratorio, previa firma de consentimiento informado avalado por el comité de ética (CEI-487). La anosmia se exploró con una prueba subjetiva para detección de olores antes del inicio de la hemodiálisis. Resultados Se incluyeron 587 pacientes. La prevalencia de anosmia fue de 0,85 % (cinco pacientes) y una incidencia de COVID-19 de 1,19 % (siete pacientes). No hubo diferencia estadística al comparar las variables demográficas, clínicas y de laboratorio entre pacientes con y sin anosmia. La presencia de anosmia tuvo una sensibilidad y un valor predictivo positivo del 0 %, pero una especificidad del 99,14 % y un valor predictivo negativo del 98,8 %. La exactitud fue del 97,9 %. Conclusiones La prevalencia de anosmia en nuestra población de hemodiálisis fue baja. Se debería indagar en el triaje cualquier síntoma (incluida la alteración del sentido del olfato) como estrategia para detectar de forma temprana casos individuales de COVID-19 o un brote en las unidades de hemodiálisis.
Background Hemodialysis patients are susceptible population for COVID-19 the disease caused by SARS-CoV-2, with early diagnosis being an urgent and needed because they are considered a population with high risk for severe and serious conditions. Purpose The objective of our study was to estimate whether sudden-onset anosmia allow to detect COVID-19 infection early in hemodialysis patients without classic symptoms (who did not present malaise, respiratory or gastrointestinal symptoms at the beginning of the disease). Methodology A diagnostic test study was accomplished during the months of September and October 2020 in three hemodialysis units in Colombia. Adult patients without classic symptoms for COVID-19 were included. Patients with previous COVID-19 infection or with a history of smell alteration were excluded. Demographic, clinical, and laboratory data were collected, prior signature of informed consent endorsed by the ethics committee. Anosmia was evaluated with objective test for odor detection before the start of hemodialysis session. Results 587 patients were included. Anosmia prevalence was 0.85% (5 patients) and the incidence of COVID-19 was 1.19% (7 patients). There was no statistically difference in demographic, clinical, and laboratory comparison between patients with and without anosmia. The presence of anosmia had a sensitivity and a positive predictive value of 0%, but a specificity of 99.14% and a negative predictive value of 98.8%. The accuracy was 97.9%. Conclusions The prevalence of anosmia in our hemodialysis population was low. Any symptoms (including altered sense of smell) should be investigated in TRIAGE as a strategy to detect early individual cases of COVID-19 or an outbreak in hemodialysis units.
ABSTRACT
Abstract Introduction Coronavirus disease 2019 (COVID-19) is a dangerous infectious disease caused by a newly discovered severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has various clinical presentations. Numerable cases with non-specific olfactory and gustatory dysfunctions in COVID-19 have been reported from all over the globe. This is important as awareness will let people to self-isolate and help in limiting disease spread. Objective To objectively evaluate the frequency of olfactory and gustatory dysfunction, which may occur independently or with other symptoms, in laboratory confirmed COVID-19 patients at an early stage of the disease. Methods Objective evaluation of olfactory and gustatory function of 322 COVID-19 patients treated at our hospital, (SMGS, Government Medical College, Jammu), from August 2020 until November 2020. Results Our study population included 127 (39.4%) males and 195 (60.6%) females. Two hundred and twenty-six (70.2%) COVID-19 patients experienced olfactory and gustatory disorders. One hundred and sixty-five (51.2%) cases experienced both olfactory and gustatory disorders. Isolated olfactory dysfunction was reported in 34 (10.6%) patients, while 27 (8.4%) patients experienced only gustatory dysfunction. Conclusion The olfactory and gustatory dysfunctions, without any nasal obstruction or rhinorrhea, are significant symptoms in the clinical presentation of early COVID-19 patients. This presentation can be recognized at the earliest one, and it can reduce the high communicability of the COVID-19 disease.
ABSTRACT
Introducción: El olfato tiene una gran importancia en la calidad de vida. Los accesos quirúrgicos selares pueden realizarse por vía transcraneal, transeptal y transnasal, y pueden generar hiposmia al incluir resecciones que afectan a la mucosa olfatoria. Objetivo: Determinar la existencia de alteración persistente en el olfato ocasionado por los accesos quirúrgicos transeptal y transnasal en pacientes operados por adenoma hipofisiario en el Instituto de Neurocirugía Dr. Asenjo. Material y Método: Estudio prospectivo de cohorte con comparación de resultados olfatorios ("sniffin' sticks" versión extendida) y encuesta SNOT-22 pre y poscirugía por adenoma hipofisiario por vía transeptal o transnasal. Se utilizaron medidas estadísticas de comparación de pruebas pareadas paramétricas y no paramétricas según las características de las variables evaluadas. Resultados: Se reclutaron 60 pacientes, completando el seguimiento 39. En 21 se realizó acceso transeptal y en 18 transnasal. Al analizar el total de pacientes y por cada técnica quirúrgica, no hubo diferencias significativas en los puntajes del "sniffin' sticks" versión extendida y tampoco en SNOT-22. Conclusión: La literatura describe incidencia de hiposmia posoperatoria muy variable, entre 0% y 88%, con mediciones subjetivas y objetivas. Existe una predilección por la técnica endoscópica a nivel internacional, por lo que cuenta con estudios de mejor calidad. A nivel nacional existen dos estudios previos que han encontrado tasas de hiposmia posoperatoria de 10% y 14%. En este estudio no hubo diferencias significativas en los puntajes obtenidos en la prueba de olfato entre el pre y posoperatorio.
Introduction: Olfaction is of great importance in quality of life. Surgical accesses to the sellar region can be performed by transcranial, transseptal, and transnasal routes, which can generate hyposmia when including resections that affect the olfactory mucosa. Aim: To determine the existence of persistent alteration in olfaction caused by transseptal and transnasal surgical accesses in patients operated for pituitary adenoma at the Instituto de Neurocirugía Dr. Asenjo. Material and Method: Prospective cohort study with comparison of olfactory results ("sniffin' sticks" extended version) and SNOT-22 survey pre and post transseptal or transnasal surgery for pituitary adenoma. Parametric and non-parametric paired test comparison statistics were used according to the characteristics of the variables evaluated. Results: 60 patients were recruited and 39 completed follow-up. 21 patients underwent transseptal access and 18 underwent transnasal access. When analyzing the total number of patients and for each surgical technique, there were no significant differences in the scores obtained in the "sniffin' sticks" extended version and neither for the SNOT-22. Conclusion: The literature describes a highly variable incidence of postoperative hyposmia, between 0% and 88%, with subjective and objective measurements. There is a predilection for the endoscopic technique at an international level, which is why it has better quality studies. At the national level there are two previous studies that have found postoperative hyposmia rates of 10% and 14%. In this study there were no significant differences in the scores obtained between pre and postoperative olfaction test.

Background: Chemosensory disturbances such as altered smell and taste sensations have a strong impact on health and quality of life. The lack of awareness of these chemosensory symptoms post-coronavirus disease (COVID)-19 vaccination has led to apprehension. When adequately addressed, it can encourage people to take vaccines which are a life-saving tool in this pandemic. Aims and Objectives: This study aims to assess the prevalence and duration of altered smell and taste post-COVID-19 vaccination. Materials and Methods: The survey was conducted during January–August 2021. The Institutional Ethical Committee clearance was obtained. Data was collected from 242 COVID-19 vaccine beneficiaries majority of them being health care workers by online and offline survey questionnaires. Descriptive analysis was done using SPSS 21. Results: Out of 250 respondents, 242 completed the study. About 95% of them received CoviShield, 3.8% Covaxin, and 1.3% Pfizer. Perception of altered smell (olfactory dysfunction), taste (gustatory dysfunction), and both smell and taste was reported by 5.8%, 8.27%, and 2.61% of study participants. The mean duration was 3.43 ± 2.03 and 4 ± 1.64 days for altered smell and taste, respectively, with complete recovery. Conclusion: Chemosensory disturbances were reported in a small percentage of vaccine beneficiaries and all of them recovered within a few days completely without any medications. Vaccines are a critical tool in the battle against COVID-19 and we should emphasize on its health and lifesaving benefits and reassure those chemosensory disturbances have complete recovery.
