Our study aimed to measure the percentage of reported olfactory or taste losses and their severity, recovery time, and association with other features in a large cohort of patients with COVID-19. Study Design. Prospective survey. Setting. Quaternary medical center and online survey. Methods. The perceived chemosensory capacities of 655 patients with confirmed COVID-19 were assessed with 11-point category rating scales (0, no function; 10, normal function). Patients were contacted in hospital, by phone calls, or by internet regarding their ability to smell or taste, and 143 were interviewed by phone 1 to 4 months later to assess the recovery of their chemosensory abilities. Results. The prevalence of self-reported olfactory, general taste, and taste quality-specific disturbances (sweet, sour, bitter, and salty) in the patients with COVID-19 were 82.4% (95% CI, 79.5%-85.3%), 76.2% (95% CI, 72.9%-79.4%), and 52.2% (95% CI, 48.3%-56.1%), respectively. The majority reported anosmia (42.9%). The presence of chemosensory symptoms was not associated with COVID-19 severity. At a median time >2 months after the onset of symptoms, rates of total and partial olfaction recovery were 53.8% and 44.7%, while complete or partial return to previous taste function was 68.3% and 27.6%. Less than 5% of the patients reported no chemosensory function improvement at all. Conclusion. The prevalence of self-reported chemosensory dysfunction is high among patients with COVID-19. Almost all patients seem to recover a significant part of their smell and taste abilities in the first 4 months after the onset of symptoms.

- Association between chemosensory impairment with neuropsychiatric morbidity in post-acute COVID-19 syndrome: results from a multidisciplinary cohort study(2023) DAMIANO, Rodolfo Furlan; NETO, Deusdedit Brandao; OLIVEIRA, Joao Vitor Ribeiro; SANTOS, Jonatas Magalhaes; ALVES, Julia Vallin Rodrigues; GUEDES, Bruno F.; NITRINI, Ricardo; ARAUJO, Adriana Ladeira de; OLIVEIRA, Melaine; BRUNONI, Andre R.; VOEGELS, Richard Louis; BENTO, Ricardo Ferreira; BUSATTO, Geraldo; MIGUEL, Euripedes Constantino; FORLENZA, Orestes V.; PINNA, Fabio de RezendePreliminary methodologically limited studies suggested that taste and smell known as chemosensory impairments and neuropsychiatric symptoms are associated in post-COVID-19. The objective of this study is to evaluate whether chemosensory dysfunction and neuropsychiatric impairments in a well-characterized post-COVID-19 sample. This is a cohort study assessing adult patients hospitalized due to moderate or severe forms of COVID-19 between March and August 2020. Baseline information includes several clinical and hospitalization data. Further evaluations were made using several different reliable instruments designed to assess taste and smell functions, parosmia, and neuropsychiatric disorders (using standardized psychiatric and cognitive measures). Out of 1800 eligible individuals, 701 volunteers were assessed on this study. After multivariate analysis, patients reporting parosmia had a worse perception of memory performance (p < 0.001). Moderate/severe hypogeusia was significantly associated with a worse performance on the word list memory task (p = 0.012); Concomitant moderate/severe olfactory and gustatory loss during the acute phase of COVID-19 was also significantly associated with episodic memory impairment (p = 0.006). We found a positive association between reported chemosensory (taste and olfaction) abnormalities and cognition dysfunction in post-COVID-19 patients. These findings may help us identify potential mechanisms linking these two neurobiological functions, and also support the speculation on a possible route through which SARS-CoV-2 may reach the central nervous system.

bookPart Epistaxe(2018) ABDO, Tatiana; BRANDãO NETO, Deusdedit; VOEGELS, Richard Louis- Sinonasal inverted papilloma: rate of recurrence and malignant transformation in 44 operated patients(2021) SBRANA, Mariana Ferreira; BORGES, Renata Ferraz Rafael; PINNA, Fabio de Rezende; NETO, Deusdedit Brandao; VOEGELS, Richard LouisIntroduction: Although sinonasal inverted papillomas are benign lesions, they are locally aggressive and have a potential malignant transformation ranging from 5% to 15%, with a high recurrence rate. Objective: The aim of this article is to describe the rate of recurrence and malignant transformation in patients with a diagnosis of inverted papilloma who underwent surgery in a tertiary hospital in Sao Paulo. Methods: We performed a retrospective analysis of patients diagnosed with sinonasal papilloma who had undergone surgery in a tertiary hospital in Sao Paulo, between August 1998 and August 2017. A patient chart review was conducted to assess data of patients' demographics, tumors characteristics, follow-up appointments, recurrence and malignancy. Inverted papillomas were analyzed and classified under the Krouse staging system. Results: A total of 69 surgeries were performed in patients with diagnosis of sinonasal papilloma. Inverted papilloma was the most prevalent subtype (49 cases - 80.33%), followed by exophytic papilloma (6 cases - 9.84%) and by oncocytic papilloma (6 cases - 9.84%). The recurrence rate was 34.09% for inverted papilloma (15/44) and the mean time of recurrence was 24.6 months. Malignant transformation occurred in 6 patients (13.64%). Three of these patients presented carcinoma in the first surgery and three patients developed carcinoma during the follow-up. Conclusion: The high recurrence rate and malignancy potential allow us to consider inverted papillomas as aggressive tumors. In a tertiary hospital in Sao Paulo the recurrence rate the mean time to recurrence is 24.6 months. The recurrence after 10 years implies was 34.09% and the need for long-term follow up. It is possible that the high recurrence rate and the high malignant transformation rate we found are due to the large number of tumors discovered at an advanced stage (most of them staged T3 and T4), secondary to poor access to health system, in developing countries.

- Mucocele: Clinical Characteristics and Outcomes in 46 Operated Patients(2019) PLANTIER, Diogo Barreto; NETO, Deusdedit Brandao; PINNA, Fabio de Rezende; VOEGELS, Richard LouisIntroduction Paranasal sinus mucocele is a benign, expansive lesion associated with paranasal sinus obstruction. It affects mostly adults, and is most common in the frontal and ethmoidal sinuses. Objective To evaluate outcomes in patients undergoing surgical treatment for paranasal sinus mucocele. Methods Retrospective review of medical records of patients treated for paranasal sinus mucocele at the ENT department of a tertiary care hospital between 2005 and 2016. Results Forty-six patients underwent surgical treatment of paranasal sinus mucocele. The mean age was 50.1 years, and 56.5% were male. The most prevalent symptom was pain, and the frontal sinus was most commonly affected. The vast majority of patients (89.1%) underwent endoscopic sinus marsupialization; 10.9% required combined open and endoscopic access. Seven recurrences occurred. Conclusion Sinus mucocele is an expansive disease that primarily affects the frontal sinus of adult patients. In most cases, endoscopic surgery is an effective treatment modality.
