xlomafota13 shared this article with you from Inoreader Comparison of Olfactory Cleft Width and Volumes in Patients with COVID-19 Anosmia and COVID-19 Cases Without Anosmia Via O.R.L. Journal for oto-rhino-laryngology and its borderlands Introduction: The aim of this study was to assess the relationship between olfactory cleft width/volume and COVID-19-related anosmia. Methods: This study consisted of PCR-proven COVID-19 patients. Cases with COVID-19-related anosmia constituted Group 1 and cases without any olfactory dysfunction (OD) throughout COVID-19 infection or after recovery constituted Group 2. A total of 50 patients were included in the study, comprising 24 cases in Group 1 and 26 cases in Group 2. Group 1 patients underwent a 4-item-odor identification test during active symptoms and a Sniffin' Sticks test after reconversion of PCR results to negative. All patients in Group 2 also underwent the Sniffin' Stick test to document normosmia. All cases had paranasal sinus CT performed. Olfactory cleft widths and olfactory volumes were measured. The differences in width and volume between groups and the correlation with odor test scores (threshold-discrimination-identification [TDI]) were calculated. In addition, regression analyzes analysis was performed for cleft widths, volumes, and TDI scores according to age. Results: Olfactory cleft widths and olfactory volumes were significantly higher in Group 1 than those in Group 2 (p = 0.001; p #x3c; 0.01). There was a significant negative correlation between total TDI scores and olfactory cleft widths and total olfactory volumes (r = −0.665; r = −0.731, respectively). Patients younger than 40 years of age had significantly higher right olfactory cl eft width, left olfactory cleft width, and olfactory cleft volume than those in patients older than 40 years of age (p = 0.004, p = 0.005, p = 0.003; p #x3c; 0,01, respectively). However, patients younger than 40 years of age had a significantly lower total TDI score and in all other values individually (t-d-i) than those in patients older than 40 years of age (p = 0.004; p #x3c; 0.01). Conclusion: Patients with COVID-19-related OD had larger olfactory cleft width and volumes than those without OD in this study. Total TDI score was found to be inversely correlated with cleft width and volume. ORL View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

The Effect of Somatosensorial System on Vestibular System

xlomafota13 shared this article with you from Inoreader The Effect of Somatosensorial System on Vestibular System Via Otolaryngology Indian Abstract The aim of this study was to investigate the effects of the somatosensory system on the vestibular system and the interconnected ways they work together to maintain balance. The study was conducted on 54 individuals (27 females and 27 males), aged between 18–25 years. vHIT as well as cVEMP tests were used to evaluate the participants. Tests were carried out while sitting, standing on firm surface and standing on foam respectively. According to the posterior vHIT results, there was a significant difference between VOR gains obtained while sitting and standing on firm surface in right side as well as on the left side (p < 0,01). Moreover, when VOR gains in standing on firm and standing on foam results were compared to each other, statistical significance was found right and left posterior canals (p < 0,05). Concerning the results obtained from VEMP, a statistically significant difference was seen in the comparison of P1-N1 amp litudes of the right side on firm surface and standing on foam (p < 0,01). When the inputs from somatosensorial system are disturbed, the parts of the vestibular system that are primarily affected are the posterior SSC, saccule and inferior vestibular nerve. This can be interpreted as the inferior vestibular nerve being more affected than the superior vestibular nerve when posture is disturbed due to somatosensory cues being unavailable or unstable.

Validation of a French version of the Sunnybrook facial grading system

xlomafota13 shared this article with you from Inoreader Validation of a French version of the Sunnybrook facial grading system Via Laryngologie Eur Ann Otorhinolaryngol Head Neck Dis. 2021 Sep 17:S1879-7296(21)00181-2. doi: 10.1016/j.anorl.2021.08.003. Online ahead of print. ABSTRACT BACKGROUND: The aim of this study was to translate the Sunnybrook Facial Grading System and its specific criteria into French and validate its use by French-speaking physicians for facial palsy evaluation. MATERIAL AND METHODS: The original English version of the Sunnybrook Facial Grading System and its specific criteria was translated into French according to international standards. Twenty videos of patients with a wide range of facial palsy in terms of duration and severity were independently rated, twice each, by 6 physicians with varied experience in facial palsy care. Internal consistency and intra- and inter-rater reliability were analyzed. RESULTS: The French version of Sunnybrook Facial Grading System and its specific criteria both showed good internal consistency, with Cronbach alph a of 0.84 and 0.86 respectively. Inter-rater reliability was excellent in both sessions for the composite score, the score of symmetry at rest and during voluntary movement and synkinesis: intraclass correlation coefficient (ICC) between 0.77 and 0.98. Intra-rater reproducibility on the composite score and subscores was also excellent and comparable for expert, experienced and novice physicians, with an average ICC of 0.95. CONCLUSION: The French version of the Sunnybrook Facial Grading System and its specific criteria is reliable, reproducible and easy to use by French-speaking teams for facial palsy evaluation.

Ki-67/MIB-1 and Recurrence in Pituitary Adenoma

xlomafota13 shared this article with you from Inoreader Ki-67/MIB-1 and Recurrence in Pituitary Adenoma Via Journal of Neurological Surgery Part B: Skull Base J Neurol Surg B Skull Base DOI: 10.1055/s-0041-1735874 Objectives Ki-67/MIB-1 is a marker of cellular proliferation used as a pathological parameter in the clinical assessment of pituitary adenomas, where its expression has shown utility in predicting the invasiveness of these tumors. However, studies have shown variable results when using Ki-67/MIB-1 association with recurrence. The purpose of this study is to determine if a high Ki-67/MIB-1 labeling index (LI) is predictive of recurrence in pituitary adenomas. Methods A retrospective chart review was performed for patients undergoing pituitary adenoma resection with at least 1 year of follow-up. Additionally, systematic data searches were performed and included studies that correlated recurrence rate to Ki-67/MIB-1 LI. Our institutional data were included in a synthesis with previously published data. Results Our institutional review included 79 patients with a recurrence rate of 26.6%. We found that 8.8% of our patients had a high Ki-67/MIB-1 LI (>3%); however, high Ki-67/MIB-1 was not associated with recurrence. The systematic review identified 244 articles and 49 full-text articles that were assessed for eligibility. Quantitative analysis was performed on 30 articles including our institutional data and 18 studies reported recurrence by level of Ki-67/MIB-1 LI. Among studies that compared Ki-67/MIB-1 ≥3 vs. <3%, 10 studies reported odds ratios (OR) greater than 1 of which 6 were statistically significant. A high Ki-67/MIB-1 had higher odds of recurrence via the pooled odds ratio (OR = 4.15, 95% confidence interval [CI]: 2.31–7.42). Conclusion This systematic review suggests that a high Ki-67/MIB-1 should prompt an increased duration of follow-up due to the higher odds of recurrence of pituitary adenoma.
