- “Benefits of the pedicled osteoplastic flap as a surgical approach of mastoidectomy in cochlear implant surgery”(2022) LOPES, P. T.; BENTO, R. F.; GEBRIM, E. M. Mello Santiago; BECK, R. M. de Oliveira; CARVALLO, R. Mota Memede; SANCHES, S. G. Gandolfi; LESSER, J. C. CisnerosObjective: To evaluate the esthetic and functional results of an osteoplastic flap for mastoid cavity closure in cochlear implant surgery. Study design: Double-blind, prospective, randomized clinical trial. Setting: tertiary referral center. Intervention(s): On hundred and twenty-six patients were randomized in 2 groups for cochlear implant surgery. Cases (n: 63) underwent simple mastoidectomy using an anteriorly pedicled osteoplastic flap for mastoid closure. In controls (n: 63), a traditional periosteal flap was used. Evaluation with the POSAS questionnaire was performed 1 year after surgery to assess surgical wound esthetics. Sixteen patients from each group had postoperative CT-scans and wideband tympanometry to assess mastoid aeration and middle ear absorbance. Gender and time after surgery were correlated. Main outcome measure(s): Evaluation of the quality of the surgical wound with the application of a questionnaire validated in the medical literature and translated into Portuguese language called POSAS, considering the perception of the blinded patient and doctor regarding the surgical technique proceeded. A lower POSAS score suggests better esthetics of the surgical wound. Secondary outcomes are volumetric measurement of aeration inside mastoid cavity using 3D computer tomography exam, which aims to analyze the influence of fibrocicatricial retraction in the surgical wound into the mastoid and the interference of its aeration volume in the absorption of sound in the middle ear, using the wideband tympanometry exam. Results: The POSAS questionnaire in the Case group showed a lower level of local pain and itchiness, a skin color and thickness more similar to the surrounding skin and less irregularity and stiffness, with no influence from time after surgery and gender compared to the Control group. The median tomographic volume was 6.37 cc in the cases and 4.60 cc in controls. Wideband tympanometry showed general smaller sound absorbance in the Case group results, specially, at 1000 Hz frequency. No intraoperative or postoperative complications were observed with the osteoplastic flap. Conclusions: This technique is an effective and safe alternative to alleviate common problems of mastoid surgery for cochlear implantation. In addition to esthetic benefits, it has less interference in middle ear physiology of sound absorbance and less fibrous tissue into the mastoid cavity during the follow-up of more than 1 year.
- Impact of Chronic Rhinosinusitis with Nasal Polyposis on IL-12 and IL-8(2023) AMARAL, J. B. do; DAVID, A. G.; MELLO, L.; BACHI, A. L. L.; VOEGELS, R. L.; THAMBOO, A.; PEZATO, R.Introduction: The pathophysiology of Chronic Rhinosinusitis is coordinated by distinct inflammatory reactions in different individuals. Inflammatory environments with a predominance of Th2 lymphocytes tend also to be rich in eosinophils. These environments are common during the formation of nasal polyps associated with aspirin intolerance, which is also marked by an increase in inflammatory mediators, especially IL-4, IL-5, and IL-13. Despite the significance of these inflammatory mediators, the relevance of IL-12 subunits' presence within eosinophilic nasal polyps, however, has been less studied. The current study aims to evaluate the presence of IL-12 subunits, IL-12p40 and IL-12p70, in eosinophilic nasal polyps and their correlations with IL-8 presence. Materials and Methods: We compared the concentrations of IL-8, IL12p40, and IL12p70 among samples of eosinophilic nasal polypoid tissue, eosinophilic nasal polypoid tissue associated with aspirin intolerance, and healthy nasal mucosa, using an indirect immunoassay (ELISA) kit. Results: When compared to healthy nasal mucosa, there was a lower concentration of IL-8 in Chronic Rhinosinusitis with Nasal Polyp (CRSwNP) tissue. Aspirin Intolerant polypoid tissue also presented a lower concentration of IL-12 subunits compared to healthy nasal mucosa. There was no significant correlation between IL-8 and IL-12 in the eosinophilic polypoid conditions. Conclusion: In CRSwNP, there is a reduction in IL-8 and IL-12 subunits compared to control, with a lack of correlation between IL-12 and IL-8. The lack of correlation can be justified by a type two inflammatory storm environment.
article 0 Citação(ões) na Scopus EVALUATION OF THE IMPACT OF EXPOSURE TO HEAT AND TO BY-PRODUCTS OF COMBUSTION ON THE HEALTH OF FIREFIGHTERS(2023) BOGGI, A. C.; AMARAL, J. B. Do; BACCHI, A. L. L.; NASCIMENTO, V. M.; VOEGELS, R. L.; SANTOS, J. M. B. Dos; GRIMALDI, G.; ARAúJO, K. Basseto de Oliveira; PAVãO, V.; PASSARETTI, D. A.; ALDRED, A.; GOMES, G.; PEZATO, R.Firefighters are often exposed to high temperatures and by-products of combustion, which can affect their health. In this study, we assessed the impact of acute exposure of firefighters in fire simulators. Twenty male firefighters were exposed to fire simulators, and observed in four phases: pre-exposure (group 0, control) and after the end of the first (group 1), second (group 2), and fourth (group 3) weeks of training. Blood samples were collected and dosed to evaluate the response of the immune, inflammatory (C-reactive protein, IL6, and IL10), and endocrine systems (cortisone, total testosterone, free testosterone, SHBG, bioavailable testosterone, TSH, and free T4). In groups 0, 1, and 3, a thermographic evaluation was also carried out to study the temperature and body heat flow of the participants. Regarding the inflammatory process, an increase in C-reactive protein and a reduction in IL-10 were observed. With respect to hormonal markers, an increase in cortisol and reduced levels of free T4 and bioa-vailable testosterone were found after exposure, with recovery of testosterone levels in the final week of training. Thermoregulatory adaptation of the organism has been associated with changes in heat flow in the organism in people subjected to extreme temperatures, with emphasis on the performance of the lower limbs. Our findings de-monstrate an inflammatory response with hormonal changes after exposure to fire and an adaptive response of thermal balance, which could aid understanding of the physiology of the human body in extreme situations.- Individualized Vibrotactile Neurofeedback Training in Patients with Chronic Bilateral Vestibulopathy(2023) BASTA, Dietmar; ROSSI-IZQUIERDO, Marcos; WONNEBERGER, Kai; BRUGNERA, Cibele; BITTAR, Roseli Saraiva Moreira; GRETERS, Mario Edvin; ERNST, Arne; SOTO-VARELA, AndresPatients with bilateral vestibulopathy (BVP) suffer from postural imbalance during daily life conditions, which in turn leads to a high frequency of falls. Unfortunately, vestibular rehabilitation has only modest and somewhat inconsistent effects in this patient group. Approximately 50% of BVP patients show an improved postural control after conventional vestibular rehabilitation training. New and more promising approaches are required. The individualized vibrotactile neurofeedback training (IVNT) in stance and gait conditions has already been described as highly effective in patients with various vestibular disorders. The purpose of the present multicenter study was to determine the efficacy of the IVNT in improving balance, reducing self-perceived disability, and improving gait in patients with confirmed BVP. In total, 22 patients performed the IVNT with the Vertiguard (R) system for 10 daily sessions. The dizziness handicap inventory (DHI), the stance stability score of the sensory organization test (SOT) and the score for everyday life mobility in stance and gait tasks (SBDT) were obtained immediately before and after the rehabilitation training period, as well as 3 and 12 months later. All measures improved significantly after the IVNT. Between 77.3% and 94.4% of patients showed an individual benefit (depending on outcome measure). The effect was not significantly reduced within the follow-up period of 12 months. The results demonstrate a high efficacy of the IVNT for vestibular rehabilitation in BVP patients.
- Olfaction in nasal polyp patients after Reboot surgery: an endotype-based prospective study(2023) GOMES, Sara Costa; DELEMARRE, Tim; HOLTAPPELS, Gabriele; ZELE, Thibaut Van; DERYCKE, Lara; BONNE, Ellen; EECKELS, Anne-Sophie; ZHANG, Nan; VOEGELS, Richard Louis; BACHERT, ClausPurpose 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-beta, 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.
- Predicting emotion perception abilities for cochlear implant users(2023) PAQUETTE, S.; DEROCHE, M. L. D.; V, M. Goffi-Gomez; HOSHINO, A. C. H.; LEHMANN, A.Objective In daily life, failure to perceive emotional expressions can result in maladjusted behaviour. For cochlear implant users, perceiving emotional cues in sounds remains challenging, and the factors explaining the variability in patients' sensitivity to emotions are currently poorly understood. Understanding how these factors relate to auditory proficiency is a major challenge of cochlear implant research and is critical in addressing patients' limitations. Design To fill this gap, we evaluated different auditory perception aspects in implant users (pitch discrimination, music processing and speech intelligibility) and correlated them to their performance in an emotion recognition task. Study sample Eighty-four adults (18-76 years old) participated in our investigation; 42 cochlear implant users and 42 controls. Cochlear implant users performed worse than their controls on all tasks, and emotion perception abilities were correlated to their age and their clinical outcome as measured in the speech intelligibility task. Results As previously observed, emotion perception abilities declined with age (here by about 2-3% in a decade). Interestingly, even when emotional stimuli were musical, CI users' skills relied more on processes underlying speech intelligibility. Conclusions These results suggest that speech processing remains a clinical priority even when one is interested in affective skills.
- White noise effect on listening effort among patients with chronic tinnitus and normal hearing thresholds(2024) OITICICA, Jeanne; VASCONCELOS, Laura G. E.; HORIUTI, Mirella B.Objective: This study investigated the effects of WN on LE in subjects with chronic tinnitus and normal hearing thresholds. The study was a prospective, non-randomized, before-and-after, intra-participant intervention. Methods: Twenty-five subjects performed the following tests: conventional and high-frequency audiometry, acuphenometry, screening questionnaires for depression and anxiety symptoms, Tinnitus Handicap Inventory (THI), Montreal Cognitive Assessment, and high WM test from the Working Memory Assessment Battery, Federal University of Minas Gerais (WMAB) as the LE measure in two conditions: No Added Noise (NAN) and with Added Noise (AN). Results: Seventeen participants (68%) performed better on AN condition. Data analysis revealed a 45% improvement in the WMAB total span count on AN setting, with a significant p value (p = 0.001). Conclusion: The subgroup of participants without traces of anxiety symptoms, up to mild traces of depressive symptoms, having unilateral tinnitus, and a THI level up to grade 2, had improved WM performance in the presence of WN, which suggests a release of cognitive resources and less auditory effort under these combined conditions.

- Perivascular Innervation in the Nasal Mucosa and Clinical Findings in Patients with Allergic Rhinitis and Idiopathic Rhinitis(2023) CARVALHO, Thiago; JR, Joao Ferreira de Mello; CALDINI, Elia Tamaso Espin Garcia; SALGADO, Daniel Calduro; CARVALHO, Nicole Mary Garcia de; DAMACENO-RODRIGUES, Nilsa Regina; VOEGELS, Richard LouisIntroduction The nonspecific hyperreactivity of rhinitis has been attributed to neurotrophins activating sensory nerves and inflammatory cells. The relationship between these markers and the intensity of the symptoms is not well established and few studies have evaluated individuals with idiopathic rhinitis.Objective The present study aims to evaluate whether perivascular innervation and nerve growth factor (NGF) are related to the intensity of the clinical conditions in allergic rhinitis (AR) and idiopathic rhinitis (IR).Methods A total of 15 patients with AR and 15 patients with IR with the indication for inferior turbinectomy (associated or not with septoplasty) were selected. The patients received a score according to their signs and symptoms. After the surgery, we quantified eosinophils, mast cells, NGF, and nerve fibers in the nasal turbinate.Results The score of the signs and symptoms was higher in the AR group. Nerve growth factor was found in the cytoplasm of inflammatory cells in the submucosa in greater quantity in the AR group. The nerve fibers were distributed throughout the tissue, mainly in the subepithelial, glandular, and vascular regions, and there was no difference between the groups. Greater perivascular innervation was associated with a higher signs and symptoms score.Conclusions We concluded that these findings suggest that the NGF produced by submucosal inflammatory cells stimulates increased perivascular innervation in rhinitis, thus directly reflecting in more intense clinical conditions, especially in AR.
- Communicative and Hearing Performance in Individuals with Cochlear Implants and Delayed Neuropsychomotor Development: A Longitudinal Analysis(2023) ROCHA, Larissa Veloso; ZABEU-FERNANDES, Julia Speranza; NETO, Rubens Vuono de Brito; MORETTIN-ZUPELARI, Marina; LOURENCONE, Luiz Fernando ManzoniIntroduction Between 15% to 30% of individuals with bilateral prelingual sensorineural hearing loss present with associated disabilities. Cochlear implant (CI) is an alternative treatment that provides consistent access to environmental and speech sounds, which results in significant benefits regarding quality of life and auditory and language development.Objectives To study the auditory and communicative performance of individuals with CI and delayed neuropsychomotor development after a minimum of five years using the device.Methods A total of eight patients were included in the study. We collected the multidisciplinary clinical records of participants, as well as the answers for the questionnaires applied remotely, which included the Children with Cochlear Implants: Parental Perspectives (CCIPP), International Classification of Functioning, Disability and Health: Children and Youth Version (ICF-CY), and the Gross Motor Function Classification System (GMFCS).Results We found that throughout the years of CI use, the auditory threshold means improved significantly in all tested frequencies, as did the speech detection threshold and the language and hearing results. Regarding parental perception, parents evaluated aspects related to their children's social relations to be positive, and had worse perceptions regarding aspects related to their education.Conclusion We observed a progression in the participants' auditory and language skills throughout the years of CI use; even in the presence of other associated disabilities. Future multicentric studies with larger samples are needed to further the advancement of rehabilitation in patients with other associated disabilities.
- Brazilian Society of Otology task force -- Vestibular Schwannoma -- evaluation and treatment(2023) SILVA, Vagner Antonio Rodrigues; LAVINSKY, Joel; PAUNA, Henrique Furlan; VIANNA, Melissa Ferreira; SANTOS, Vanessa Mazanek; IKINO, Claudio Marcio Yudi; SAMPAIO, Andre Luiz Lopes; LOPES, Paula Tardim; LAMOUNIER, Pauliana; MARANHAO, Andre Souza de Albuquerque; SOARES, Vitor Yamashiro Rocha; POLANSKI, Jose Fernando; DENARO, Mariana Moreira de Castro; CHONE, Carlos Takahiro; BENTO, Ricardo Ferreira; CASTILHO, Arthur MeninoObjective: To review the literature on the diagnosis and treatment of vestibular schwannoma. Methods: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on vestibular schwannoma were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. Results: The topics were divided into 2 parts: (1) Diagnosis audiologic, electrophysiologic tests, and imaging; (2) Treatment wait and scan protocols, surgery, radiosurgery/radiotherapy, and systemic therapy. Conclusions: Decision making in VS treatment has become more challenging. MRI can diagnose increasingly smaller tumors, which has disastrous consequences for the patients and their families. It is important to develop an individualized approach for each case, which highly depends on the experience of each surgical team.(c) 2023 Associacao Brasileira de Otorrinolaringologia e Cirurgia C ' ervico-Facial.
- Synovial chondromatosis of the temporomandibular joint-clinical, surgical, and imaging findings of a Milgram stage III case series(2023) MACHADO, Gustavo Grothe; ZAMBON, Camila Eduarda; LIMA, Jose Manuel da Silva de; PAIVA, Gustavo Luiz Alkmin; MARTINS, Victor Adriano de Oliveira; PERES, Maria Paula Siqueira de MeloSynovial chondromatosis of the temporomandibular joint (TMJ) isa rare disease characterized by cartilaginous metaplasia of the mesenchymal remnants of the synovial membrane with formation of loose cartilaginous nodules. It is prevalent in middle-aged women and the main clinical characteristics are swelling, pain, and limited jaw movements. Diagnosis is difficult, especially in the early stages, because the signs and symptoms are like other TMJ diseases such as internal derangements and tumors. Imaging exams are fundamental in differential diagnosis for detection of synovitis and free cartilaginous bodies. Magnetic resonance imag-ing with a gadolinium contrast would be of particular interest for this purpose. Treatment involves the removal of the cartilaginous nodules and synovectomy. It can be performed by arthroscopy or arthrotomy depending on the size of the lesion, the number of corpuscles, and the need for auxiliary surgical procedures. Final diagnosis is anatomopathologic. Postoperative follow-up is nec-essary due to the risk of recurrence. (Oral Surg Oral Med Oral Pathol Oral Radiol 2023;135:e94-e101)

- Inside-Out Transcanal Endoscopic Mastoidectomy: Literature Revision(2023) BESSA, Renan Goncalves; TSUJI, Robinson KojiIntroduction Recently, there have been significant advancements in transcanal endoscopic ear surgery (TEES). The combination of rigid and thin otoendoscopes with high-definition cameras enabled a less invasive transcanal access to the middle ear and a clearer view of the surgical field. Several surgeons have recently published studies about cholesteatoma resection via transcanal endoscopic surgery, even in cases where the disease has extended to the mastoid, requiring transcanal endoscopic mastoidectomy. Objectives To analyze the currently available literature on transcanal endoscopic inside-out mastoidectomy, and to determine its efficacy as a surgical technique by evaluating the disease's relapse/recurrence rate. Data Synthesis Initially, the titles and abstracts of articles identified were analyzed. At this stage, 117 articles were analyzed, 97 of which were excluded for not meeting the inclusion criteria. The 20 remaining articles were further evaluated. The articles were classified on the basis of five levels of scientific evidence. Final Comments The analysis of the studies showed that the transcanal endoscopic approach is effective in providing access to the attic or antrum, especially in cases of sclerotic mastoids. There was only one study with grade A recommendation, which showed the efficacy of endoscopic ear surgery in the treatment of cholesteatoma. Furthermore, there were three studies with grade B recommendation, showing less relapse/recurrence after TEES. More studies with grade A and B recommendations are needed to better evaluate the effectiveness of TEES, especially compared with that of traditional microscopic surgery.
- What does the video head impulse test tell us about post-caloric vestibular recruitment?(2023) MEZZALIRA, R.; BITTAR, R. S. M.Objective: The vestibular recruitment observed in caloric testing is a new tool in the study of the vestibulo-ocular reflex. This study aimed to determine the sensitivity and specificity of the video head impulse test to detect post-caloric vestibular recruitment. Method: In this cross-sectional study, all participants underwent the standard otoneurological assessment of the service, caloric test, and video head impulse test. A non-linear mixed model was used to test for associations. Results: The study group consisted of 250 (89 male and 161 female) patients, with a mean age of 54.84 years. The control group comprised 35 participants, 18 men and 17 women, with a mean age of 40.42 years. Sex and age had no effect on group responses. There was no difference between the study and control groups regarding the interaction between recruitment and gain (p = 0.7487); recruitment and overt (p = 0.7002) and covert saccades (p = 1.0000); and recruitment and anti-compensatory saccades in the contralateral ear (p = 0.3050). The video head impulse test had a sensitivity of 51% and a specificity of 50% as a predictor of post-caloric recruitment. Conclusion: The video head impulse test results showed no relevance in predicting post-caloric vestibular recruitment. & COPY; 2022 Associac,a & SIM;o Brasileira de Otorrinolaringologia e Cirurgia C & PRIME;ervico-Facial.
- Upper airway modifications after weight loss: a systematic review(2023) SOARES, Carolina Ferraz de Paula; CAHALI, Michel BurihanObjective: Weight loss is one of the most often prescribed treatments to reduce the level of sleep apnea severity; however, objective assessment of airway alterations after loss of weight has only been studied in the last decades. This study aimed at evaluating alterations after weight loss reported in the literature.Methods: A literature review was performed in the medical databases: PubMed, Web of Science, Scopus and Embase. A total of 681 articles were found in the databases and after evaluation only 10 studies were selected for data extraction.Results: Most studies observed an increase of the area in the retropalatal region; some indicat-ing that this increase occurred mostly in the lateral pharyngeal region. Studies with volumetric reconstruction showed a significant reduction in parapharyngeal fat deposits, lateral wall and tongue fat, and volumetric reduction in all soft tissues of the pharynx, pterygoid and genioglos-sus muscles. Studies evaluating craniofacial bone structures showed a reduction in the airway height by bringing the hyoid closer to the posterior nasal spine and a reduction in the distance from the hyoid to the chin.Conclusion: There is a limited number of studies with a good level of scientific evidence evaluating changes in the upper airways after weight loss and how these changes impact obstructive sleep apnea. The studies included in this review indicate that weight loss increases the airways space by reducing the volume of the parapharyngeal structures, particularly at the retropalatal site, where there is an apparent gain in the lateral area of the airway and hyoid relocation. & COPY; 2022 Associacao Brasileira de Otorrinolaringologia e Cirurgia C & PRIME;ervico-Facial.
- Upper Airway Mucociliary Clearance is Impaired in Dyspneic COVID-19 Patients(2023) PEZATO, Rogerio; DAVID, Andrea Goldwasser; BOGGI, Alexandre Coelho; MELO, Bruna; ROSALINO, Claudia Maria Valete; RODRIGUEZ, Athenea Pascual; THAMBOO, Andrew; VOEGELS, Richard LouisCovid-19 is transmitted mainly by respiratory droplets and as the upper airway mucosa is the first innate immune barrier, it is crucial to understand the effects of SARS-CoV-2 on this system. In the current study, we aimed to evaluate the nasal mucociliary clearance in patients with SARS-CoV-2 infection and their symptom development. Observational cross-sectional study. The nasal mucociliary clearance (NMC) time was evaluated by the saccharin test and the results were compared between patients with SARS-CoV-2 infection (group 1) and controls (group 2, asymptomatic patients with a negative polymerase chain reaction test). We also compared the NMC time for each specific symptom suffered by participants in group 1 with the NMC time of the control group as well as with the patients in group 1 who were asymptomatic. There was a significant increase in NMC time in group 1 with dyspnea when compared to the control group (p = 0.032) and also when compared to patients who were infected were not dyspneic (p = 0.04). There were no differences in the clearance times when considering other symptoms. COVID-19 patients with dyspnea present with altered nasal mucociliary clearance.
- Outcomes of Endoscopic Sinus Surgery for Chronic Rhinosinusitis in Adults with Primary Ciliary Dyskinesia(2023) PLANTIER, Diogo Barreto; PINNA, Fabio de Rezende; OLM, Mary Anne Kowal; ATHANAZIO, Rodrigo; PILAN, Renata Ribeiro de Mendonca; VOEGELS, Richard LouisIntroduction Primary ciliary dyskinesia (PCD) is a rare inherited disease associated with impairment of mucociliary transport and, consequently, with a high incidence of chronic rhinosinusitis. For patients with chronic rhinosinusitis who remain symptomatic despite medical treatment, endoscopic sinus surgery is a safe and effective therapeutic option. However, to date, no studies have been found evaluating the effect of surgery on the quality of life associated with the effect on olfaction and nasal endoscopy findings of patients with primary ciliary dyskinesia and chronic rhinosinusitis.Objective To describe the effect of endoscopic sinus surgery on the quality of life, on olfaction, and on nasal endoscopy findings of adults with PCD and chronic rhinosinusitis.Methods Four patients who underwent endoscopic sinus surgery were included. The Sinonasal Outcome Test-22 (SNOT-22) score, the Nasal Obstruction Symptom Evaluation (NOSE) questionnaire, and the Lund-Kennedy score were collected preoperatively and at 3 and 6 months postoperatively. The olfaction as assessed with the University of Pennsylvania Smell Identification Test (UPSIT), which was administered preoperatively and 3 months postoperatively.Results A total of 4 patients with a mean age of 39.3 years old (3 men and 1 woman) completed the study. All patients showed clinically significant improvement in the SNOT-22, NOSE, and Lund-Kennedy scores at 3 months postoperatively, and this improvement was sustained throughout the follow-up period. However, olfaction did not improve after surgery.Conclusion The endoscopic sinus surgery treatment of chronic rhinosinusitis in adults with PCD was associated with improvement in quality of life and endoscopic findings. However, no improvement in olfaction was demonstrated. Studies with a larger number of patients and control groups should help confirm these findings.
- Computational fluid dynamics and NOSE scale to assess nasal respiratory function, and correlation with linear maxillary measurements after surgically assisted rapid maxillary expansion(2023) ZAMBON, C. E.; CHEROBIN, G. B.; UTUMI, E. R.; MACHADO, G. G.; VASCONCELLOS, F. A. F. de; PERES, M. P. S. M.; PILAN, R. R. M.; VOEGELS, R. L.; PINNA, F. R.Nasal obstruction is common in patients with a transverse maxillary deficiency. The aim of this study was to determine the variation in nasal airway resistance in adult patients with a transverse maxillary deficiency before and after surgically assisted rapid maxillary expansion (SARME) by computational fluid dynamics (CFD) using computed tomography scans, and to correlate this variation with maxillary linear measurements obtained by means of plaster models. The subjective symptoms of nasal obstruction were also analysed using a visual analogue scale (VAS) for nasal breathing and the Nasal Obstruction Symptom Evaluation (NOSE) scale. There was a median reduction of 21% in nasal airway resistance post SARME (P = 0.002). The NOSE scale score decreased (P < 0.001) and nasal breathing quality VAS scores increased in both nostrils (P < 0.001). Transverse measurements between the upper canines (C-C), premolars (PM-PM), and molars (M-M), and maxillary perimeter showed significant increases (P < 0.001), while the anteroposterior maxillary arch length showed a significant decrease (P = 0.016). An inverse proportional correlation was found between PM-PM and nasal airway resistance (r = -0.395; P = 0.034) and between M-M and nasal airway resistance (r = -0.383; P = 0.040). These results demonstrate that surgically expanding the posterior region of the maxilla results in decreased nasal airway resistance, decreased obstructive symptoms, and improved patient respiratory quality.
- Generation of four induced pluripotent stem cells lines from PBMC of the DFNA58 family members: Two hearing-impaired duplication carriers (USPi006-A e USPi007-A) and two normal-hearing noncarriers (USPi004-A and USPi005-A)(2023) KOBAYASHI, Gerson S.; VIEIRA-SILVA, Gleiciele A.; VARELLA-BRANCO, Elisa; MOREIRA, Danielle P.; KITAJIMA, Joao Paulo F. W.; HEMZA, Claudia R. M. L.; MINGRONI-NETTO, Regina C.; LOJUDICE, Fernando H.; OITICICA, Jeanne; BENTO, Ricardo F.; BATISSOCO, Ana C.; LEZIROVITZ, KarinaThe DFNA58 locus contains a genomic duplication involving three protein-coding genes (CNRIP1, PLEK, and PPP3R1 & PRIME;s exon 1) and other uncharacterized lncRNA genes (LOC101927723, LOC107985892 and LOC102724389). To clarify the role of these genes in hearing and precisely determine their role in hearing loss, four iPSC lines were generated from two carriers and two noncarriers of the duplication.
- Outcomes of Early Versus Late Tracheostomy in Patients With COVID-19: A Multinational Cohort Study(2022) SHRECKENGOST, C. S. Harrell; FOIANINI, J. E.; ENCINAS, K. M. Moron; GUARACHI, H. Tola; ABRIL, K.; AMIN, D.; BERKOWITZ, D.; CASTATER, C. A.; DOUGLAS, J. M.; GRANT, A. A.; KHULLAR, O. V.; LANE, A. N.; LIN, A.; NIROULA, A.; NIZAM, A.; RASHIED, A.; REITZ, A. W.; ROSER, S.

Talal; TIRADO, G.; BENíTEZ, C. Yánez; WEISER, T. G.; BARRY, M.; BOECK, M.; FARRELL, M.; GREENBERG, A.; MILLER, P.; PARK, P.; CAMAZINE, M.; DILLON, D.; SMITH, R. N.OBJECTIVES: Timing of tracheostomy in patients with COVID-19 has attracted substantial attention. Initial guidelines recommended delaying or avoiding tracheostomy due to the potential for particle aerosolization and theoretical risk to providers. However, early tracheostomy could improve patient outcomes and alleviate resource shortages. This study compares outcomes in a diverse population of hospitalized COVID-19 patients who underwent tracheostomy either ""early""(within 14 d of intubation) or ""late""(more than 14 d after intubation). DESIGN: International multi-institute retrospective cohort study. SETTING: Thirteen hospitals in Bolivia, Brazil, Spain, and the United States. PATIENTS: Hospitalized patients with COVID-19 undergoing early or late tracheostomy between March 1, 2020, and March 31, 2021. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: A total of 549 patients from 13 hospitals in four countries were included in the final analysis. Multivariable regression analysis showed that early tracheostomy was associated with a 12-day decrease in time on mechanical ventilation (95% CI, -16 to -8; p < 0.001). Further, ICU and hospital lengths of stay in patients undergoing early tracheostomy were 15 days (95% CI, -23 to -9 d; p < 0.001) and 22 days (95% CI, -31 to -12 d) shorter, respectively. In contrast, early tracheostomy patients experienced lower risk-adjusted survival at 30-day post-admission (hazard ratio, 3.0; 95% CI, 1.8-5.2). Differences in 90-day post-admission survival were not identified. CONCLUSIONS: COVID-19 patients undergoing tracheostomy within 14 days of intubation have reduced ventilator dependence as well as reduced lengths of stay. However, early tracheostomy patients experienced lower 30-day survival. Future efforts should identify patients most likely to benefit from early tracheostomy while accounting for location-specific capacity. Copyright © 2022 The Authors.
