Multiple sclerosis attack case presenting with pseudo-vestibular neuritis.

PURPOSE: Pseudo-vestibular neuritis is a clinical diagnosis for patients presenting with acute vestibular syndrome due to a central pathology. CASE REPORT: We reported a case of multiple sclerosis characterized by pseudo-vestibular neuritis. Our case was a 32-year-old male patient. The patient, who was diagnosed with multiple sclerosis in September 2019, came to the emergency clinic in January 2020 with the complaint of severe vertigo, vomiting-nausea. A newly developed demyelinating plaque was detected in the left vestibular nucleus in cranial MRI. The patient had no hearing loss. On examination of the patient, nystagmus findings supporting peripheral vestibular involvement were present on the left side. Neurologic examination showed left-sided hyperactive deep tendon reflexes, Achilles clonus, dysmetria, ataxia to the left and plantar reflex with extensor response on the left. Video head impulse test and cervical evoked myogenic potential tests were performed. Vestibular hypofunction was present on the left side. Steroid pulse therapy was administered as 1000 mg/day, i.v for 7 days. After treatment, his complaints decreased. In addition, there was an improvement in examination findings. CONCLUSION: Multiple sclerosis is shown to be an etiological factor in patients with pseudo-vestibular neuritis.

Evaluation of the Effect of Topical Application of Nigella sativa on Acute Radiation-Induced Nasal Mucositis.

The goal of this study was to demonstrate the effect of radiotherapy (RT) on nasal mucosa in rats and to evaluate the radioprotective effects of the topical application of black seed oil (Nigella sativa [NS]) to treat acute radiation-induced nasal mucositis.A total of 18 rats were randomized into 3 groups, with 6 animals per group. The rats in group 1 were topically administered saline in the nasal cavity after sham irradiation. Group 2 received saline at the same dose after irradiation. Group 3 was given NS after irradiation. The rats in groups 2 and 3 were irradiated with a single dose of 40 Gy to the nasal and paranasal area. Only one drop of saline (0.05 mL) was applied to each nostril in the first, second, and third days after RT in groups 1 and 2. One drop of cold press NS (0.05 mL) was applied to each nostril in group 3. Fourteen days after irradiation, the nasal mucosal tissues were excised for histopathological evaluation. Vascular dilatation, inflammatory cell infiltration, superficial erosion, and formation of exudates were classified according to the severity.No evidence of mucositis was observed in group 1. Of all the parameters the only statistically significant difference between groups 2 and 3 were observed for "superficial erosion' (P < 0.05). Overall microscopic observations in the NS-treated group were better than in group 2.The preliminary results of our study have shown that local application of NS to the nasal mucosa may be an effective treatment of acute nasal mucositis due to RT.

Comparison of Voice Quality and Cost Effectiveness of Endoscopic Cordectomy Using Microdissection Electrodes with Laser Cordectomy and Radiotherapy.

OBJECTIVE: To compare the acoustic parameters and the cost effectiveness achieved after endoscopic cordectomy using radiofrequency microdissection electrodes (ECRM) with those of transoral laser cordectomy and radiotherapy. METHODS: The study included 81 disease-free patients previously treated for early larynx carcinoma (30 with ECRM, 27 with transoral laser cordectomy, 24 with primary radiotherapy). Post-treatment voice analysis was performed in all patients. Additionally, the cost effectiveness of all treatment procedures was calculated. RESULTS: The GRBAS (G: Grade, R: Roughness, B: Breathiness, A: Asthenia, and S: Strain) scale showed a significant difference between the groups (p<0.001). The mean values for perceptive assessment score in the radiotherapy group were significantly lower than those in the ECRM group (p<0.05). There were no significant differences between the ECRM group and the transoral laser cordectomy group in terms of the perceptive assessment scores (p>0.05 for all). Percent jitter, percent shimmer and fundamental frequency (F0) were significantly different in the radiotherapy group than the ECRM and the transoral laser cordectomy groups (p<0.05). Maximum phonation time (MPT) in the radiotherapy group was significantly longer than the ECRM and transoral laser cordectomy groups (p<0.001). There were no significant differences between the ECRM group and the transoral laser cordectomy group in terms of the MPT (p>0.05). The mean cost of the ECRM technique was statistically lower than the other treatment techniques (p<0.05). Moreover, the length of hospital stay after ECRM was statistically significantly shorter than was after laser cordectomy (p<0.05). CONCLUSION: Objective and perceptive voice analysis after ECRM showed comparable results with transoral laser cordectomy, but poorer results than radiotherapy. Cost effectiveness of ECRM was found to be better than the other two treatment techniques.

Effect of Body Mass Index on Auricular Morphology and Auditory Functions.

In this study, we aimed to investigate the relationship between the body mass index (BMI) and the morphometric properties of auricula and its acoustic gain characteristics. A total of 45 participants between 18 and 45 years of age were enrolled into the study. Participants' height and weight measurements were recorded for the BMI calculation. On both sides, the morphometric properties of the auricula were measured and recorded. Additionally, the participants were subjected to multidirectional dynamic real ear measurements (REMs) to specify the intensity and frequency values of the maximum hearing gain. Participants consisted of 24 women and 21 men. The mean BMI was 23.42. The mean auricular area was 22.70 cm2. Statistically significant positive correlation was found between the auricular area and BMI (r = 0.427, P = .03). The mean postauricular sulcus angle was 20.99°. The mastoid-helix distance was 16.07 mm. There was no statistically significant correlation between BMI level and postauricular sulcus angle and mastoid-helix distance (P > .05). The mean dynamic REM measurement was evaluated. The maximum acoustic gain at anterior, lateral, and posterior vectorial stimulation was calculated as 20.9, 24.2, and 20.7 dB Sound Presure Level (SPL), respectively. Statistically significant negative correlation was found between the three directions acoustic gain level and BMI in the statistical examination (r = -0.365, r = -0.386, r = -0.453, respectively, and P < .05 for all). The results of acoustic gain frequency were 2967.4, 2963, and 2934 Hz, respectively. There was no statistically significant correlation between acoustic gain frequency and BMI (P > .05). When participants were grouped according to their BMI, participants with a BMI >25 had a statistically significantly bigger auricular area and lower maximum acoustic gain when compared with those with BMI <25 (P < .05). We found that the auricular area increased with BMI. We think that this is related to soft tissue thickening of the auricula related to high BMI. In addition, we found that the acoustic gain level decreased inversely with BMI. We believe that the decrease in acoustic gain is due to the increase of acoustic resistance after the increase of soft tissue thickness. In conclusion, we think that BMI has a negative effect on auditory function according to findings in our study.
