RESUMO
OBJECTIVES: The new corona virus infection, has a wide range of clinical manifestations. Fever and cough are the most common symptoms. The olfactory function may be also affected with COVID-19. In this randomized clinical trial, we wanted to evaluate the therapeutic effect of olfactory training with and without oral vitamin A for COVID-19-related olfactory dysfunction. METHODS: Patients answered to the standard Persian version of anosmia reporting tool and performed the quick smell test before and after 12 weeks and at the end of the 12 months follow up. The patients were randomly allocated to three groups; Group A treatment with olfactory training, Group B treatment with oral vitamin A and olfactory training, and Group C as control group which only underwent nasal irrigation twice a day. Patients were treated for 3 months and followed up for 12 months. RESULTS: Totally 90 patients were included in three groups. After interventions, 76.9% of patients in Group A, 86.7% of patients in Group B, and 26.7% of patients in Group C completely improved. The average intervention time was statistically significant in relationship with the final olfactory status of the patients in the 12 months follow-up. The olfactory training has significantly improved the smell alteration at the end of 3- and 12- months follow-up in A and B groups. CONCLUSION: A three-months olfactory training is effective for improvement of COVID-19-related olfactory dysfunction. Adding daily oral vitamin A to olfactory training did not lead to better results in improving olfactory dysfunction. LEVEL OF EVIDENCE: Step 2 (Level 2*): Randomized trial.

OBJECTIVE: This study aimed to investigate the prevalence and factors associated with olfactory dysfunction in individuals exposed to Isotretinoin (ISO) for the treatment of acne, using the University of Pennsylvania Smell Identification Test (UPSIT®). METHODS: This cross-sectional study enrolled age and sex-matched patients with acne who were current users of oral ISO and unexposed controls without olfactory complaints. UPSIT® and a validated questionnaire (Nasal Obstruction Symptom Evaluation) were administered to evaluate nasal obstruction in patients exposed to ISO. RESULTS: A total of seventy patients were recruited, with 35 in the exposed group and 35 in the unexposed group, consisting of 18 males and 17 females in each group, aged from 17 to 47 years. The prevalence of olfactory dysfunction was higher in the exposed group compared to the non-exposed group (62.9% vs. 17.1%), yielding a Prevalence Ratio (PR) of 3.7 (95% CI 1.9-7.1). However, no participants were categorized as anosmia or severe hyposmia and the majority of dysfunction was mild hyposmia compared to moderate hyposmia (51.5% vs. 11.4%). Among the exposed individuals, gasoline, orange, coffee, and wood exhibited the highest rates of identification errors (≥54%). Olfactory function demonstrated a negative correlation with treatment duration (pâ¯=â¯0.01), cumulative dose (pâ¯=â¯0.02), and nasal obstruction (pâ¯=â¯0.02). CONCLUSIONS: Olfactory dysfunction was more prevalent among ISO users, despite the patients being unaware of the disorder. Olfactory changes were correlated with treatment duration, cumulative dose, and nasal obstruction. LEVEL OF EVIDENCE: Level 4.

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.

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 1 st to the 2 nd 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.

RESUMO
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.
RESUMO
Abstract Background Olfactory dysfunction (OD) represents a frequent manifestation of the coronavirus disease 2019 (COVID-19). Apolipoprotein E (APOE) is a protein that interacts with the angiotensin-converting enzyme receptor, essential for viral entry into the cell. Previous publications have suggested a possible role of APOE in COVID-19 severity. As far as we know, no publications found significant associations between this disease's severity, OD, and APOE polymorphisms (E2, E3, and E4). Objective To analyze the epidemiology of OD and its relationship with APOE polymorphisms in a cohort of Long-COVID patients. Methods We conducted a prospective cohort study with patients followed in a post-COVID neurological outpatient clinic, with OD being defined as a subjective reduction of olfactory function after infection, and persistent OD being defined when the complaint lasted more than 3 months after the COVID-19 infection resolution. This cross-sectional study is part of a large research with previously reported data focusing on the cognitive performance of our sample. Results The final sample comprised 221 patients, among whom 186 collected blood samples for APOE genotyping. The persistent OD group was younger and had a lower hospitalization rate during the acute phase of the disease (p < 0.001). Furthermore, the APOE variant E4 allele frequency was lower in this group (p = 0.035). This study evaluated OD in an outpatient population with COVID-19. In the current literature on this disease, anosmia is associated with better clinical outcomes and the E4 allele is associated with worse outcomes. Conclusion Our study provides new information to these correlations, suggesting APOE E4 as a protective factor for OD.
Resumo Antecedentes A disfunção olfatória (DO) é uma manifestação frequente da doença do coronavírus 2019 (COVID-19). A apolipoproteína E (APOE) é uma proteína que interage com o receptor da enzima conversora de angiotensina, essencial para a entrada viral na célula. Publicações anteriores sugeriram um possível papel da APOE na gravidade da COVID-19. Até onde sabemos, nenhuma publicação encontrou associações significativas entre a gravidade dessa doença, DO e polimorfismos da APOE (E2, E3 e E4). Objetivo Analisar a epidemiologia da DO e sua relação com os polimorfismos do gene APOE em uma coorte de pacientes com COVID longa. Métodos Um estudo de coorte prospectiva com pacientes acompanhados em ambulatório neurológico pós-COVID, com DO sendo definida como uma redução subjetiva da função olfativa após a infecção e a DO persistente sendo definida quando a queixa durou mais de 3 meses após a resolução da infecção por COVID-19. Este estudo transversal é parte de uma pesquisa maior com dados anteriormente relatados, focando na performance cognitiva dos pacientes. Resultados Foram selecionados 221 pacientes para esse estudo, dos quais 186 haviam coletado amostras de sangue para genotipagem APOE. O grupo DO persistente foi mais jovem e apresentou menor taxa de internação na fase aguda da doença (p < 0,001). Além disso, a frequência do alelo E4 da APOE foi menor nesse grupo (p = 0,035). Este estudo avaliou a DO em uma população com COVID longa. Na literatura atual sobre essa doença, a anosmia está associada a melhores desfechos clínicos e o alelo E4 está associado a piores desfechos. Conclusão Nosso estudo acrescenta novas informações a essas correlações, sugerindo a APOE E4 como um fator de proteção para DO.
RESUMO
Patients with adult Refsum Disease (ARD) have retinitis pigmentosa and thus nyctalopia, anosmia, sensorineural deafness, polyneuropathy, and ataxia. Upon physical examination, patients with ARD have congenital short metacarpals, metatarsals, and cardiac arrhythmias. Manifestations due to the lack of phytanoyl-CoA hydroxylase in peroxisomes needed for alpha-oxidation of phytanic acid lead patients to accumulate phytanic acid in their body tissues. To our knowledge, no consensus for clinical diagnostic criteria for patients with ARD has been published. Our patient had nyctalopia, retinal findings, and visual field results compatible with retinitis pigmentosa. Additionally, the patient had decreased macular thickness and volume in both eyes, the findings being worse in the left eye. The patient had undergone hand surgery due to chronic pain in both hands, as well as his fourth and fifth metatarsal bones were shortened. Interestingly, audiology evaluation showed mild hearing loss in the right ear and mild to moderate hearing loss in the left ear. Inheritance patterns in patients with ARD have been described. Physical examination, phytanic acid evaluation, and genetic studies may all help reach an ARD diagnosis. This is the first report of adult Refsum disease in Puerto Rico.
RESUMO
OBJECTIVES: Healthcare workers (HCWs) may have different response to Bacillus Calmette-Guérin (BCG) vaccination due to previous occupational exposure to Mycobacterium particles. We report subgroup analysis of the BATTLE trial, comparing BCG effects in HCWs vs non-HCWs. This was a secondary analysis of a trial. METHODS: The BATTLE trial was a double-blind placebo-controlled phase III clinical trial that investigated BCG revaccinating adults who were recently infected with SARS-CoV-2 virus. BCG and placebo recipients were sub-grouped based on regular occupational contact with patients into HCWs (48 BCG and 50 placebo) and non-HCWs (124 BCG and 134 placebo). Weekly COVID-19 symptom progression and injection site reactions were compared between subgroups on weeks one, two, three, and six follow-ups. RESULTS: HCWs were more likely to complain of itching on the injection site early after injection (OR = 2.5, p = 0.049). They developed peeling and crusting on the site of injection faster than non-HCWs (during the second week, p = 0.033 and 0.040, OR = 3.3 and 2.7, respectively). HCWs were also more likely to maintain their papule or develop a late onset pustule during later weeks (weeks four and six, p = 0.024 and 0.006, OR = 2.2 and 8.6, respectively). In terms of COVID-19 symptom progression, recovery from anosmia was more likely in the non-HCWs who received BCG (week six, pHolm's corrected = 0.002, OR = 3.3). CONCLUSION: HCWs' local reaction to BCG injection was slightly more rapid and more intense, possibly due to their occupational exposure. BCG may also ameliorate COVID-19 induced inflammation and anosmia in non-HCWs but not HCWs. Therefore, HCWs might be less likely to benefit from BCG vaccination. CLINICALTRIALS: gov register number NCT04369794.
RESUMO
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.
RESUMO
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.

BACKGROUND: Previous studies demonstrated the difficulty of patients with Head and Neck Cancer (HNC) in sensing food taste, a function in which olfaction has a significant role. However, neither study employed psychophysical tests or control groups to establish the veracity of such complaints. AIMS/OBJECTIVES: In this study, we quantitatively tested the olfactory function of HNC individuals and compared their function to that of healthy controls. METHODS: Thirty-one HNC naïve treatment patients and thirty-one controls, matched for sex, age, schooling, and smoking, were tested with the University of Pennsylvania Smell Identification Test (UPSIT). RESULTS: The olfactory function was significantly worse among the patients diagnosed with head and neck cancer [UPSIT cancer = 22.9(CI 95%: 20.5-25.4) vs. UPSIT controls = 29.1(CI 95%: 26.9-31.3); p < .001]. Most patients with HNC had olfactory disorders (n = 29, 93.5%). The risk of olfactory loss was higher in the cancer group [OR: 10.5(CI 95%: 2.1-51.9; p = .001)]. CONCLUSION AND SIGNIFICANCE: Olfactory disorders can be detected in more than 90% of patients with head and neck cancer when evaluated using a well-validated olfactory test. Smell disorders may be a potential marker for early diagnosis of HNC.

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.

RESUMO
PURPOSE: To report biomarkers present in the olfactory mucosa in chronic rhinosinusitis with nasal polyps (CRSwNP) in comparison with nasal polyps and to nasal mucosal tissues from control patients. To evaluate the kinetics of smell over 6 months in patients who underwent Reboot surgery. METHODS: Cohort study from May 2021 to May 2022. We collected samples of olfactory mucosa and nasal polyps from 16 CRSwNP patients and inferior turbinate samples from 20 control subjects. The study was not randomized for surgical and/or medical treatment. Samples were analyzed by Luminex and Unicap 100 to measure biomarkers of inflammation (IL1-ß, IL4, IL5, IL6, IL17, CCL3, CCL4, G-CSF, SE-IgE, total IgE and ECP). 12 of the CRSwNP patients underwent Extended Sniffin'tests at timepoints 1-4 days pre-surgery, and 1, 3 and 6 months after Reboot surgery. RESULTS: Type-2 markers were significantly elevated in OM and polyp tissue in CRSwNP (n = 16) vs. controls (n = 20), P < 0.05. TDI scores improved already 1 month (P < 0.05) after surgery and remained stable for 6 months. Type-2 inflammation in nasal polyps was associated with decreased sense of smell and taste before surgery, but improved after surgery (P = 0.048). Type-3 inflammation was present in the olfactory mucosa and was associated with a better sense of smell before surgery, but a smaller improvement of smell afterward. CONCLUSIONS: Type-2 inflammation is present in the olfactory mucosa in CRSwNP patients and is associated with smell loss. Reboot surgery, aiming to completely remove inflamed sinus mucosa, significantly improves the smell in this group of patients.

PURPOSE: The decrease in smell in the elderly population is frequent and considered a natural process. However, sometimes it can be associated with the decline of cognitive functions, and it is considered a warning for the early stage of neurodegenerative diseases and social impairment. OBJECTIVE: To assess the prevalence of olfactory dysfunction in previous healthy elderly that attended a tertiary hospital in Brazil as escorts and the clinical alterations associated in this population. METHODS: Subjects 60 years or over attending the University Hospital of Campinas were evaluated. Each participant answered a questionnaire, followed by an otorhinolaryngological exam with flexible nasal endoscopy and the Connecticut smell test produced by the Connecticut Chemosensory Clinical Research Center (CCCRC). Elderly people with nasosinusal diseases or with a history of nasal surgery were excluded. RESULTS: Of the total of 103 participants, 16 (15.5%) reported olfactory complaints and 68 (66%) presented impairment in the olfactory test. It was observed that older individuals showed more changes in olfactory function (p = 0.001). Gender, education, lifestyle, comorbidities, medications in use and exposure to pollutants did not influence the impairment olfactory function of this population. CONCLUSIONS: There is a significant prevalence of olfactory dysfunction in the elderly population evaluated. Most of these elderlies also present an inability to identify odours, not having awareness of this olfactory impairment.

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.
RESUMO
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.

RESUMO
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.

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.
