RESUMO
PURPOSE: To assess the knowledge and confidence level regarding the basic first-aid for treating epistaxis among medical staff, including nurses and physicians across various medical disciplines. The study focused three aspects of first aid management: location of digital pressure, head position and duration of pressure. METHODS: The study involved 597 participants, categorized into five groups according to their specialties: emergency medicine, internal medicine, surgery, pediatrics, and community-based healthcare. A paper-based multiple-choice questionnaire assessed knowledge of managing epistaxis. Correct answers were determined from literature review and expert consensus. RESULTS: Most medical staff showed poor knowledge regarding the preferred site for applying digital pressure in epistaxis management. For head position, pediatricians and internal medicine physicians were most accurate (79.4% and 64.8%, respectively, p < 0.01), and nurses from the emergency department outperformed nurses from other disciplines; internal medicine, surgery, pediatrics, and community-based healthcare (61.1%, 41.5%, 43.5%, 60%, 45.6%, respectively, p < 0.05). While most medical staff were unfamiliar with the recommended duration for applying pressure on the nose, pediatricians and community clinic physicians were most accurate (47.1% and 46.0%, respectively, p < 0.01), while ER physicians were least accurate (14.9%, p < 0.01). Interestingly, a negative correlation was found between years of work experience and reported confidence level in managing epistaxis. CONCLUSIONS: Our findings indicate a significant lack of knowledge concerning epistaxis first-aid among medical staff, particularly physicians in emergency departments. This finding highlights the pressing need for education and training to enhance healthcare workers' knowledge in managing epistaxis.
RESUMO
OBJECTIVES: Tumor depth of invasion is a known prognostic factor in several head and neck cancers, but data on early laryngeal squamous cell carcinoma (SCC) are sparse. In this study, we aim to determine whether radiological tumor thickness serves as a prognostic factor in early SCC of the glottis treated with radiation. METHODS: One hundred thirty-two adult patients (age >18 years) underwent pretreatment computed tomography (CT) and were treated with radiation for pathologically proven early stage (T1 or T2) glottic SCC. Thirty-eight were excluded because the tumor could not be correctly identified on the CT scan, and an additional three patients because of insufficient data. RESULTS: The final cohort consisted of 91 patients, 84 (90.3%) men and 7 (9.7%) women aged 39.86-86.53 (mean 65.55 ± 12.76) years. Mean tumor thickness was 0.59 ± 0.19 cm in patients with T1 tumors and 0.79 ± 0.21 cm in patients with T2 tumors. The optimal cutoff value for 5-year disease-free survival (DFS), using the Youden index (sensitivity: 81.2%, specificity 65.3%), was 0.7 cm. A significant advantage in 5-year overall survival (OAS) and 5-year DFS for tumor thickness of <0.7 cm (P = 0.01 and P < 0.01, respectively) was found, these findings were consistent also when each stage was examined separately (T1 vs T2). CONCLUSION: Radiological tumor thickness appears to significantly predict OAS and DFS in early glottic SCC patients. IMPLICATION FOR PRACTICE: Tumor thickness may be considered as an auxiliary aid in deciding follow-up time and frequency, proper treatment, and determining prognosis.
RESUMO
BACKGROUND: Partial Tonsillectomy (PT) is an alternative method to treat sleep disordered breathing (SDB) and/or obstructive sleep apnea (OSA). The current guidelines do not differentiate it from traditional tonsillectomy. Thus, children younger than 3 years old undergoing PT are admitted for surveillance similar to traditional tonsillectomy due to possible postoperative complications. The aim of this study is to assess the risks of PT in children 3 years old and younger, compared to older children. METHODS: Children underwent inpatient partial tonsillectomy and/or adenoidectomy, due to SDB/OSA, from 2018 to 2020. A special protocol was designed, including follow-up at 2-, 4-, 6-, 8- and 24-h after surgery. Variables analyzed included visual analogue pain score, oral intake, oxygen saturation, pulse rate, postoperative hemorrhage, urine output, temperature, analgesics and fluid administration. Furthermore, major interventions were recorded. Comparison of all variables between children younger than 3 years old with older children was performed. RESULTS: Ninety-two children were included; mean age of the whole cohort was 44.5 ± 21.9 months. Thirty-five (38%) children were 3-years old or younger and n = 57 (62%) were older than 3 years old, with no significant statistical difference in sex (p = 0.22). Mean age in the younger group was 25.7 ± 6.9 months, and 56.1 ± 20.1 months in the older group. In total we had 7 children with post-operative complications; 4 with fever, 3 with low intake. There were no major interventions recorded in either group. The complications were more common in the older group (n = 5) than the younger group (n = 2) without a statistical significance (p = 0.59). There were no differences in VAS, use of painkillers, oral intake, urine output, oxygen saturation and tachycardia among the two groups. CONCLUSION: This study supports that children undergoing ambulatory PT may be at low risk of complications, regardless of age.

STATEMENT OF PROBLEM: The accuracy of virtual interocclusal records has been evaluated, but clinical studies comparing the clinical output to the virtual design are lacking. PURPOSE: The purpose of this clinical study was to evaluate the agreement between the virtual occlusal scheme designed by a computer-aided design and computer-aided manufacturing software program and the occlusal scheme obtained clinically on the definitive prosthesis assessed with articulating paper. MATERIAL AND METHODS: The virtual occlusal scheme design of 20 single monolithic crowns and their adjacent teeth was obtained by using an intraoral scanning system in 17 participants. These registrations were compared with conventional occlusal records obtained by applying articulating paper in 2 stages: first with 200-µm blue film and the second with 12-µm metallic red articulation tape. The analysis included both the quantity and the quality of the contacts of the conventional occlusal records referred to as the standard method. For accuracy analysis, virtual record sensitivity was calculated per crown as the percentage of true positive virtual contacts of the actual contacts identified by articulating paper. Specificity was also calculated as the percentage of true negative virtual contacts of the actual sites of clearance. RESULTS: The virtual record sensitivity was 98.5 (95% confidence interval [CI] 96-100) for the crowns and 95 (95% CI 85-100) for the adjacent teeth. The virtual record specificity was 88.6 (95% CI 82.4-94.8) for the crowns and 82.6 (95% CI 77.5-87.6) for the adjacent teeth. The agreement between the clinical and virtual contact intensities on the crowns was 83 (95% CI 73-93) and 67.3 (95% CI 56-78.7) for the adjacent teeth. The positive predictive value was 72.83 (95% CI 60-86). The negative predictive value was 100% (95% CI 100-100). CONCLUSIONS: The intraoral scanning system provided clinically sufficient sensitivity and specificity for identifying the occlusal surface contacts of monolithic crowns. A slight decrease was detected in the system's sensitivity and specificity in identifying contacts on adjacent teeth and a larger decrease identifying the intensity of these contacts.
RESUMO
OBJECTIVE: To investigate whether dysregulated thyroid hormone function is associated with Bell's palsy. STUDY DESIGN: Cross-sectional. SETTING: Electronic medical record database of Clalit Health Services (CHS). CHS is an Israeli payer-provider, integrated health care system, serving >4.5 million members (54% of the Israeli population). PATIENTS: Older than 18 years with Bell's palsy, during 2002 to 2019. INTERVENTIONS: None. METHODS: A total of 1,374 patients with Bell's palsy who had thyroid-stimulating hormone (TSH) blood levels measured up to 60 days before the palsy were matched (1:2) for age and sex with 2,748 controls who had TSH blood levels and no history of Bell's palsy. RESULTS: Retrospective review of the CHS database, from 2002 to 2019 yielded 11,268 patients with Bell's palsy, of which, 1,374 met the inclusion criteria. Mean age was 57.9 years, and 61.4% were female. A higher percentage of patients in the Bell's palsy group had low TSH (≤0.55 mIU/L) compared with controls (5.7% vs. 3.6%, p < 0.001). Low TSH compared with TSH > 0.55 mIU/L, was independently associated with 1.45-fold increased odds for having Bell's palsy (95% CI 1.11-2.02, p < 0.001), when controlled for age, sex, body mass index, diabetes, hypertension, prior cerebrovascular accident, hemoglobin level, and purchasing thyroid hormone drugs. Among the patients with TSH ≤ 0.55 mIU/L, 95.5% had normal free thyroxin and 97.7% had normal free triiodothyronine levels (subclinical hyperthyroidism). For 47.1% of patients, TSH remained ≤0.55 mIU/L, 3 to 12 months after the Bell's palsy occurred and most patients had normal free thyroxin (95.4%) and normal free triiodothyronine (91.8%). CONCLUSIONS: Subclinical hyperthyroidism is independently associated with Bell's palsy after controlling for multiple confounding factors.

INTRODUCTION: The treatment paradigm for chronic rhinosinusitis with nasal polyps (CRSwNP) is complex, consisting of a combination of conservative, medical and surgical management. High rates of recurrence despite current standard of care has led to the search for treatments that can improve outcomes and limit the treatment burden for patients living with this chronic condition. AREAS COVERED: Eosinophils are granulocytic white blood cells that proliferate as part of the innate immune response. IL5 is an inflammatory cytokine implicated in the development of eosinophil-associated diseases that has emerged as a target for biologic therapy. Mepolizumab (NUCALA) is a humanized antiIL5 monoclonal antibody that represents a novel therapeutic approach to CRSwNP. The results of multiple clinical trials are encouraging but its real-world implementation requires a thorough cost-benefit analysis across a range of clinical situations. EXPERT OPINION: : Mepolizumab is an emerging biologic therapy that shows promising potential for the treatment of CRSwNP. It appears to provide both objective and subjective improvement as an addon therapy to standard of care treatment. Its specific role in treatment algorithms remains a topic of discussion. Future research surrounding its efficacy and cost effectiveness as compared to alternative options is needed.

BACKGROUND: Reprocessing of nasopharyngoscopes represents a large financial burden to community physicians. The aim of this study was to perform a cost analysis of nasopharyngoscope reprocessing methods at the community level. METHODS: Electronic surveys were distributed by email to community otolaryngologists. Surveys were comprised of 14 questions assessing clinic size, nasopharyngoscope volume, scope reprocessing method and maintenance. Four manual techniques were evaluated: (1) soak with ortho-phthalaldehyde solution (Cidex-OPA; Advanced Sterilization Products, Johnson and Johnson Inc., Markham, Canada), (2) soak with accelerated hydrogen peroxide solution (Revital-Ox; Steris Canada Inc., Mississauga, Canada), (3) disinfection with chlorine dioxide wipe (Tristel Trio Wipes System; Tristel plc., Cambridgeshire, UK), (4) UV-C light system (UV Smart, Delft, The Netherlands). All costs are reported in CAD, and consumable and capital costs for reprocessing methods were obtained from reported vendor prices. Time costs were derived from manufacturer recommendations, the Ontario Medical Association Physician's Guide to Uninsured Services, and the Ontario Nurses Association Collective Agreement. Cost analyses determined the most cost-effective reprocessing method in the community setting. Sensitivity analyses assessed the impact of reprocessing volume and labour costs. RESULTS: Thirty-six (86%) otolaryngologists responded and answered the survey. The cost per reprocessing event for Cidex-OPA, Revital-Ox, Tristel and UV system were $38.59, $26.47, $30.53, and $22.74 respectively when physicians reprocessed their endoscopes themselves. Sensitivity analyses demonstrated that Revital-Ox was the least costly option in a low volume, however, the UV system remained the most cost effective in higher volumes. The cost per reprocessing event when done by clinic staff was $5.51, $4.42, $11.23 and $6.21 for Cidex-OPA, Revital-Ox, Tristel and the UV system. CONCLUSIONS: The UV light system appears to be the most cost-effective method in high volumes of reprocessing, and Revital-Ox is cheaper in lower volumes and when performed by clinic staff rather than physicians. It is important to consider the anticipated work volume, shared clinic space and number of co-workers prior to choosing a reprocessing method.

PURPOSE: Synchronous virtual care rapidly expanded worldwide amid the COVID-19 pandemic to provide remote medical assessment, minimizing contact and disease transmission risk. Despite its benefits, such an abrupt expansion has shed light on the need to address patients' level of satisfaction with this service delivery. The purpose of this study was to investigate patients' satisfaction, travel cost, productivity loss, and CO2 emissions involved with synchronous virtual care and in-person assessments in rhinology and sleep apnea clinics. MATERIALS AND METHODS: This prospective comparative study included patients managed via virtual care, or in-person clinic visit at St. Joseph Hospital, London, Canada, from December/2020 to April/2021, with rhinology pathologies or sleep apnoea. Patient satisfaction questionnaire (PSQ-18) scores were assessed. The overall scores of respondents were recorded including cost implications. RESULTS: A total of 329 patients were invited, 28.5 % responded (n = 93). 33 virtual care (age 48 ± 6), and 60 in-person (age 51 ± 19). There was no statistical significance in PSQ-18 scores. However, under a diagnosis-based subgroup analysis, allergic rhinitis patients on virtual care presented a significantly lower PSQ-18 scores on the general satisfaction (3.28 vs. 4.25, p = 0.04). The time spent with the doctor was directly correlated with age for patients seen in-person (r = 0.27; p = 0.037). The estimated loss of productivity for the Virtual care group was CAD 12, patients assessed in-person presented an average loss of productivity about six times higher (CAD 74 ± 40). CONCLUSIONS: Overall patients' satisfaction did not depend on whether they were seen virtually or in-person. However, time spent with the doctor contributed to higher satisfaction levels, but only among older patients who were seen in person. Nonetheless, allergic rhinitis patients seemed less satisfied with the virtual care option. Virtual care demonstrates economic benefits.

PURPOSE: To investigate the consistency between the international guidelines recommendations and worldwide standard practices regarding diagnostic work-up and follow-up strategies for managing patients with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) in the era of monoclonal antibodies. METHODS: A questionnaire developed by the Rhinology section of the Young Otolaryngologists of the International Federation of Oto-rhino-laryngological Societies (Yo-IFOS) included items regarding the management of CRSwNP patients, monoclonal prescription, surgical and follow-up procedures, awareness of biologicals availability, and other relevant clinical practices. The online survey was directed to otolaryngologists and distributed in Europe, North America, South America, and the Middle East through otolaryngological and/or rhinological societies. RESULTS: A total of 202 responses were analyzed; the mean participants' age was 45 ± 11 (73% men and 27% women), and 31% were from the United States, Canada 19%, Europe 45%, Middle East and South America 5%. Only 60% of the respondents declared using validated symptoms and endoscopic score systems in their clinical practice. Several practice discrepancies emerged in our cohort, including preferred surgical approach, prescription of preoperative oral steroids, and perioperative antibiotics (59% and 58%, respectively), as well as divergent awareness levels of available biologics for CRSwNP worldwide. CONCLUSIONS: CRSwNP needs a complex and time-consuming assessment, according to the latest guidelines. There seems to be a gap between these recommendations and the real-world data, which should draw more attention to bringing them into uniform clinical practice in the near future.

OBJECTIVES: To evaluate the safety and outcomes of powered intracapsular tonsillotomy and adenoidectomy (PITA) for the treatment of sleep disordered breathing in infants up to 36 months of age compared to older children. METHODS: This retrospective analysis included children who underwent PITA from 2013 to 2019 at a single tertiary care medical center. The patients were divided into 2 groups: up to 36 months, and 36 to 72 months. The data were collected from electronic medical records and from a telephone survey based on a modified version of the OSA-18 questionnaire. Post-operative complications, and short- and long-term outcomes were compared. RESULTS: A total of 48 patients met the inclusion criteria for the main study group (up to 36 months of age). They were compared to 59 children 36 to 72 months of age. There were no differences in subjective outcomes between age groups (P = .65). There were no differences in the frequency of post-operative complications between age groups (P = .8) or in the number of hospitalization days (P = .91). CONCLUSION: The short- and long-term outcomes and safety of PITA for the treatment of sleep disordered breathing in infants up to 36 months of age are similar to those of older children.

Introduction: Retraction pockets and marginal perforations of the pars tensa of the tympanic membrane (TM) are most commonly found at superior posterior quadrant (SPQ). The patulous Eustachian tube tends to manifest in the same quadrant. Variation in the structure of the TM may explain these observations. Material and Methods: A line defined by the manubrium was used to divide the pars tensa into anterior and posterior portions. A transverse line centered on the umbo divides the pars tensa into superior and inferior parts, resulting in four quadrants. Surface areas of each of the TM quadrants were measured in a sample of 23 human adult formalin-fixed temporal bones. The TMs were completely excised, faced medially, and placed against graph paper to maintain scale measurements, photoed, and measured.TM thickness was measured on a different set of 20 human temporal bones (TB) preparations with normal external and middle ears. Four random loci were chosen from each pars tensa's TM quadrant. The thickness was measured using high-magnification power microscopy. Results: The SPQ was the largest and thinnest of the four quadrants. It occupies 31% of the pars tensa area. It is 69 µm as compared to approximately 85 µm in the other quadrants. The radial lines between the umbo and the annulus are in descending order from superior posterior toward the anterior-superior radials. Conclusion: The SPQ has the largest vibratory area and is the thinnest of the four TM quadrants. Variation in the thickness of the middle, fibrous layer accounts for the variation in the thickness of the TM. These findings may explain the tendency of pathologies related to Eustachian tube dysfunction to preferentially manifest in or originate from the SPQ.
RESUMO
BACKGROUND: Dysphagia is a common symptom with diverse etiologies and refers to disorders of the process of swallowing food or fluids. Many studies have reported the anatomical and functional differences between men and women in swallowing in healthy patients; however, sex discrepancies in symptomatic patients have not often been studied. OBJECTIVES: To compare the performance of men and women with dysphagia using videofluoroscopy. METHODS: To compare the performance of men and women with dysphagia using videofluoroscopy. RESULTS: A total of 203 patients met the inclusion criteria, 106 men (52%) and 97 women (48%). Men complained significantly more about choking on liquids (P = 0.002) and in swallowing pills (P = 0.004) compared to women. Men had more abnormalities in the pharyngeal phase (P = 0.015) and at the upper esophageal sphincter (P = 0.056). The prevalence of aspiration, penetration, and barium residue in the hypopharynx and in the vallecula were significantly greater in men as well. CONCLUSIONS: In patients with dysphagia, women had fewer subjective symptoms and performed better than men in videofluoroscopy especially in the pharyngeal phase. These differences are probably due to different anatomical and functional swallowing characteristics. A better understanding of these discrepancies can be useful in offering tailored treatment in clinical practice.

PURPOSE: The aim of this study was to assess the frequency and types of compensatory articulations (CAs) in nonsyndromic patients with velopharyngeal dysfunction (VPD) and various palatal anomalies and to determine the relationship between the frequency of CAs, type of palatal anomaly, and phonological errors. METHOD: A total of 783 nonsyndromic, Hebrew-speaking patients with VPD and various palatal anomalies (cleft lip and palate [CLP], cleft palate [CP], submucous CP [SMCP], occult submucous CP [OSMCP], or non-CP) were studied retrospectively. Perceptual VPD tests, including articulation and phonological assessment, were conducted. CAs were described as below the level of the defect in the vocal tract (abnormal backing of oral targets to post-uvular place) or in front of it within the oral cavity (palatalization) and at the velopharyngeal port. RESULTS: Among 783 patients, 213 (27.2%) had CAs. Most CAs (18.4%) occurred below the level of the defect, followed by CAs at the velopharyngeal port (12.0%) or in front of it (4.9%). No differences were found in the frequency of CAs between patients with CP (47.8%) or CLP (52.6%) and between those with non-CP (13.6%) or OSMCP (14.7%). SMCP patients had lower frequency of CAs (29.8%) than CP (p = .003) and CLP (p = .002) patients but higher frequency than OSMCP (p = .002) and non-CP (p = .002) patients did. Among the 783 patients, 247 (31.5%) had phonological errors. A higher frequency of phonological errors was found in patients with CAs (55.4%) compared to those without (22.6%) and in all palatal anomaly groups except CLP (31.4% vs. 23.9%). CONCLUSIONS: CAs in nonsyndromic patients with VPD remained relatively high in all age groups, up to adulthood. CAs are influenced by inadequate velar length following palatal repair, as well as by oral structural abnormalities, whereas poor muscle function due to OSMCP and/or abnormal size and/or shape of nasopharynx has less influence. Errors produced in front of the velopharyngeal port are influenced by the structural anomaly of CLP. This information may contribute to general phonetic and phonological theories and genetic investigations about CP anomalies.

INTRODUCTION: This study aimed to identify the characteristics of cranial-base morphology in platybasic and nonplatybasic patients with palatal anomalies and velopharyngeal dysfunction (VPD) compared with control subjects to investigate structural factors related to craniofacial morphology that affect the nasopharyngeal space and may influence velopharyngeal function, and to develop precise treatments for specific patients with VPD. METHODS: Three hundred eighty-six patients with VPD and various palatal anomalies were studied retrospectively. The control group included 126 healthy patients with normal speech. Lateral cephalometric images assessed craniofacial morphology. RESULTS: Nonplatybasic patients and control subjects had larger SNA, S-Ba-Ptm, and N-Ba-PP angles (in the craniomaxillary complex), and platybasic patients had larger nasopharyngeal ANS-Ptm-Ve and Ba-S-Ptm angles and longer Ve-T and Ve-Ba distances than the nonplatybasic patients. All study patients had larger ANB, Gn-Go-Ar, and PP-MP angles (in the craniomandibular complex). Nonplatybasic patients had smaller Ba-SN angles than platybasic patients and controls because of more acute N-S-Ptm angle. Among the nonplatybasic patients, Ve-T length tended to be shorter (with no significant difference between groups) and located more inferiorly (because of the smallest ANS-Ptm-Ve angle) in relation to the maxilla. Thus, the nasopharynx was narrower horizontally but longer vertically than in patients with platybasia. CONCLUSIONS: Cranial-base flexure influences the shape of the skull base and facial-skeletal structure and may alter the pharyngeal space between them. This finding should help improve preoperative planning regarding the effect of the pharyngeal flap height relative to the nasopharynx and oropharynx ratio that affects surgical outcomes, such as resonance and residual VPD. In patients with Class III malocclusion and maxillary constriction, careful planning of presurgical orthodontic treatment is needed in maxillary advancement procedures. Orthodontic and surgical collaboration can help prevent postoperative VPD, especially in platybasic patients.

BACKGROUND: Nivolumab, an immune checkpoint inhibitor is used to treat advanced metastatic malignancies. Data showed that nivolumab can cause exacerbated response of T-Helper 2 cells and lead to airway inflammation. OBJECTIVE: To present the upper airway findings of a 69-year-old woman after treatment with nivolumab. METHODS: Case report. RESULTS: A 69-year old woman with no history of chronic rhinosinusitis developed complaints of nasal congestion, rhinorrhea, sneezing, and anosmia. These symptoms started after one year of treatment with nivolumab. Pale polyps were observed on fiberoptic endoscopy examination. A gradual increase in eosinophil blood counts was noted. On histopathology, heavy infiltrates of eosinophils were seen in the tissue. CONCLUSIONS: Nivolumab is used to treat various advanced metastatic malignancies, with a good safety profile. Nevertheless, physicians must be alert to the possibility of evolving type II inflammation in patients, as appropriate therapy can be provided to improve their quality of life.

PURPOSE: To investigate the recovery of loss of smell and taste among recovered COVID-19 patients. MATERIALS AND METHODS: This cross-sectional follow-up study is a sequel to a study by Biadsee et al. Among the previous study population of 128 non-hospitalized patients, positive for COVID-19 by reverse transcription-polymerase chain reaction (RT-PCR), 97 patients participated in a survey designed for this study. Information and data regarding loss of smell and taste, rate of recovery, xerostomia, and additional symptoms; (Cough, Myalgia, Weakness, Rhinorrhea, Nasal congestion) were collected. RESULTS: A total of 43 men and 54 women were included. Mean age was 37.5 years (range 19-74). Mean follow-up was 229 days (range 191-253). Sixty-five patients reported gustatory dysfunction during the disease of which 61.5% reported full recovery, 38.5% partial recovery. Of 65 patients who reported olfactory impairment during the disease, 52% had full recovery and 48% reported partial recovery of olfactory function. Complete recovery of olfactory function was positively associated with full recovery of gustatory function (p = 0.01). Gender did not significantly affect the recovery of OD and GD (p = 0.45, p = 0.90, respectively). Patients who experienced olfactory dysfunction as an initial symptom had lower rates of olfactory complete recovery (p = 0.043). CONCLUSION: After a mean follow-up of 229 days, complete recovery of smell and taste functions occurred in 52% and 61.5%, respectively. However, dysfunction persisted in 48%-38.5% of patients.
