ABSTRACT

Background: A major problem with the University of Pennsylvania Smell Identification Test (UPSIT) is its poor sensitivity for malingering detection in a group of people familiar with the test mechanism. This study aimed to evaluate the modification of UPSIT to detect anosmia malingering. Methods: This was a pilot experimental study conducted in 2019 in Tehran. The participants were 60 healthy subjects classified into two groups of 30 people. The first group was requested to deliberately feign a negative result on the Iranian version of UPSIT, Iran Smell Identification Test (ISIT) (malingering group). The second group consisted of participants, who did not scratch the odorant part of ISIT during the tests (anosmia group). ISIT was modified in two steps. At each step, one incorrect option was deleted from the available choices. The number of each group's answers, altered away from the correct choice, was then calculated and compared. Results: The coached malingering group participants were able to feign anosmia in the original ISIT exam. In the modified ISIT, the number of answers changed from correct to wrong during the second stage (from three available choices to two choices) was significantly higher in the anosmia group (P<0.001). In the ROC analysis, the area under the curve was 0.92 (P<0.001). The cut-off of 4.5 for this test showed 93% sensitivity, 82% specificity, and 90% PPV and NPV. Conclusion: The ISIT is not capable of detecting malingering in the coached participants, yet by deleting the choices step-by-step, the sensitivity and specificity of the test increased.

ABSTRACT

BACKGROUND: Rhinosinusitis involves inflammation within the paranasal sinuses and the nasal mucosa. It is a very common chronic health condition. This paper performs a validation process on the Persian translation of the rhinosinusitis quality-of-life questionnaire (RhinoQOL), for use in clinical assessment of chronic rhinosinusitis (CRS) patients. The Lund-Mackay score is also used widely in assessing CRS, and this study aims to describe its relationship to RhinoQOL. METHODS: The Persian RhinoQOL adaptation was carried out on 110 CRS patients. A follow-up questionnaire was completed two weeks later. Psychometric properties were determined by statistical analysis (reliability, reproducibility, validity, responsiveness). A total of 45 patients were included for radiologic score calculation. The Spearman's test was used for assessing the correlation between the RhinoQOL scores and Lund-Mackay score. RESULTS: Internal reliability was excellent for the impact scale (Cronbach's alpha=0.92). Cronbach's alpha was 0.63 and 0.55 for frequency and irritation scales, which reflects lower internal consistency values. Temporal stability or Test-retest reliability was excellent across all three scales. ICC was 0.96, 0.97, and 0.99 for RhinoQOL frequency, irritation, and impact scales. No significant correlation was observed between the Lund-Mackay score and RhinoQOL scores in terms of frequency, irritation and impact scales. CONCLUSION: The Persian version of RhinoQOL appears to be as reliable, valid, and sensitive to change as the English version.

ABSTRACT

Obstructive sleep apnea (OSA) has various complications for individuals' health. This study aimed to evaluate the factors for referring obstructive sleep apnea patients to otolaryngologists in Iranian residency entrance examination volunteers. This cross-sectional study recruited volunteer participants from the Iranian Residency Entrance Examination on March 2, 2018. The Obstructive Sleep Apnea Knowledge and Attitudes (OSAKA)/the Obstructive Sleep Apnea Knowledge and Attitudes in Children (OSAKA-KIDS) Questionnaires were distributed among residents attending exam preparation. Number of years working as a physician, number of adult and pediatric patients visited during the academic rank in residency examination, and the main specialty during general physician education in which they get familiar with obstructive sleep apnea were documented. The effect of the mentioned variables evaluated on patient referral preference specialty. Of the 95 volunteers, 57.9% were female; mean age was 29.6 ± 3.3 years. The overall knowledge score of the OSAKA questionnaire was 9.85 ± 3.9 and for the OSAKA-KIDS questionnaire was 9.2 ± 4.9. In patients under 18 years of age, the most frequent referrals were from otolaryngology specialists (51.2%). The only factor which had positive significant effect on adult patient referral preference was source of obstructive sleep apnea knowledge during general physician taring (p < 0.001). Given the low awareness about OSA in candidates for the residency entrance exam and the high importance of this treatable disease, the need for comprehensive training courses during residency is warranted and the adequacy of sleep apnea education through all involved specialty during general physician education should be improved.

ABSTRACT

INTRODUCTION & OBJECTIVE: The aim of the present study was to determine the efficacy of long-acting betamethasone, and its comparison with Dexamethasone as an intratympanic injection in the treatment of Sudden Sensorineural Hearing Loss (SSNHL). MATERIALS AND METHODS: Thirty-one patients who do not respond to systemic steroids and poor prognosis patients were enrolled in this study. The patients divided randomly into two groups: 1- Dexamethasone and 2- Long acting betamethasone. Dexamethasone (0.4 ml/mg) or long-acting betamethasone (0.1 ml/mg) was slowly injected (0.4 to 0.6 cc) into the superior-anterior area of the tympanic membrane as 6 injections twice a week for a total of 3 weeks. Right after the treatment and one, two and six months after completion of treatment, an audiometry was performed and compared with the pre-injection values. RESULTS: Speech Reception Threshold (SRT) showed improvements in both groups immediately after treatment and in the follow-up period, compared to baseline. Speech Discrimination Score (SDS) also improved in both groups directly after treatment and at one-month follow-up. The hearing improvement in the Dexamethasone group was clinically better than in the Beta group, but due to the non-parametric data, it was not possible to analyze the hearing improvement process in the variable group. CONCLUSION: According to the results obtained in this study, intratympanic corticosteroid injection in the treatment of patients with SSNHL has positive and promising results on improving hearing level.

ABSTRACT

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the ability of recognizing some important elements of the skull base in axial CT-scan cuts, including the optic canal (OC), superior orbital fissure (SOF), vidian canal (VC), foramen rotundum (FR), jugular foramen (JF) and hypoglossal canal (HC). METHODS: In this study, 25 otolaryngology residents and 25 recently graduated otolaryngologists were evaluated in terms of their recognition of skull base elements, using 30 axial CT-scan cuts. Two months later, the exam related to skull base CT scans was taken in groups after a brief anatomy courses for otolaryngology residents. RESULTS: The percentage of correct answers from otolaryngology residents regarding OC, SOF, VC, FR, JF, and HC in the first exam were 74 ± 26, 47 ± 34, 65 ± 30, 41 ± 38, 58 ± 26, and 68 ± 32, respectively. The correct answer for each element was similar between groups, and the differences were not statistically significant (p > 0.05). p value for the differences observed regarding the percentage of correct answers for the second exam between trained otolaryngology residents and recent otolaryngology graduates regarding OC and JF was no significant (p > 0.05) but significant for the other elements with better result in trained otolaryngology residents and most for SOF (p > 0.0001). CONCLUSION: This study showed that the ability of recognition for the mentioned elements in axial CT-scan cuts was low among otolaryngology residents and graduated otolaryngologists. The proposed novel method for distinguishing SOF from OC had a powerful and long-lasting effect on trainee.
