ABSTRACT OBJECTIVE: This study uses the multi-feature paradigm to compare the MMN responses of individuals with normal hearing thresholds, including the high frequencies with and without tinnitus. METHODS: Sixteen subjects with chronic subjective idiopathic tinnitus and twenty matched healthy controls were included in the study. Participants with hearing thresholds (0.125-16 kHz) less than 20 dB HL and MoCA test scores above 21 were included in the study. MMN responses and topographical maps of the responses resulting from the multi-feature MMN paradigm were recorded from 22 surface scalp electrodes. Amplitude and latency parameters of the MMN responses of five different deviants, consisting of frequency, intensity, duration, location, and silent gap, were compared between the two groups. RESULTS: The amplitudes of MMN responses were lower in the tinnitus group than in the control group at Fz electrode for all deviant types. At the same time, there was no difference between the groups for MMN latencies and, no correlation was found between THI and MMN. CONCLUSION: According to our results, the MMN might indicate a possible impairment in pre-attentive and automatic central auditory processing for chronic tinnitus patients. Since MMN responses in the tinnitus group differ from those of healthy individuals, it might be used as a reference for evaluating the central auditory pathways of tinnitus patients.

Online ahead of print. ABSTRACT We report a case of cochleovestibular neurovascular compressive syndrome (CVCS)-induced drop attack treated with microvascular decompression (MVD) of the superior vestibular nerve. This report discusses the merits of surgical intervention through a review of related literature. A 58-year-old woman was referred to our clinic with a chief complaint of intermittent, strong, right-sided tinnitus lasting for a few seconds immediately prior to drop attack. Magnetic resonance imaging (MRI) showed bilateral neurovascular contact between the anterior inferior cerebellar artery (AICA) and the vestibulocochlear nerve. Based on MRI findings, history of present illness, and response to anticonvulsants, CVCS was suspected, and surgical decompression on the right side was subsequently performed. The patient became asymptomatic immediately after the surgery, and the vestibular-evoked myogenic potentials were normalized. No recurrence was reported during a 1-year follow-up period.

xlomafota13 shared this article with you from Inoreader Neuroectodermal tumours of the sino-nasal tract: a clinicopathological study of 18 cases with a newly proposed revised classification and a brief review of literature Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Sep 27. doi: 10.1007/s00405-021-07051-6. Online ahead of print. ABSTRACT AIM: Sino-nasal tract tumours constitute 3% of the head and neck malignancies. Among these tumours, neuroectodermal tumours are rare with histo-morphological and immunohistochemical overlap making them a challenge for the pathologist. We included Ewing's/PNET, olfactory neuroblastoma (OFN), mucosal malignant melanomas (MMM), Melanotic neuroectodermal tumour of infancy (MNTI), small-cell neuroendocrine carcinoma (SNEC), and the newest entity Adamantinoma like Ewing's sarcoma (ALES) as part of the neuroectodermally derived tumours of the sino-nasal tract. The last three entities were added to the existing ones, which also has been emphasized in this paper. METHODS AND RESULTS: A comprehensive analysis was done on all neuroectodermally derived tumours from 2016 to 2020. A total of 18 cases were collected, which included OFN (10 c ases), SNEC (2 cases), MMM (2 cases), Ewing's/PNET (2 cases), MNTI (1 case), and ALES (1 case). The most common presentation in NE tumours was nasal obstruction (80-100%). Except for OFN, all other tumours were confined to the nasal and paranasal sinuses. 4/10 cases of OFN showed orbital extension. Cervical lymph-node metastasis was seen in 50% of cases of SNEC and MMM groups. An array of relevant immune-histochemical markers were performed. The marker expression was very subtle among the groups. On follow-up, recurrence was seen in the OFN and MMM groups in 30 and 50%, respectively. Metastasis was seen in SNEC group (100%) and OFN group (10%). CONCLUSION: As sino-nasal neuroectodermal tumours pose a diagnostic challenge and have different therapies and are prognostically different, the pathologist must be aware of the subtle morphological, immunohistochemical clues which have been dealt with in-depth in this study.

Med Oral Patol Oral Cir Bucal. 2021 Sep 25:24870. doi: 10.4317/medoral.24870. Online ahead of print. ABSTRACT BACKGROUND: Angina bullosa haemorrhagica (ABH) is characterized by the recurrent appearance of blood blisters on the oral mucosa, mainly in adults' soft palate. In general, the blisters rupture spontaneously, lacking the necessity for biopsy. We report the clinical features of 23 ABH cases, emphasizing the clinical behavior and the management of these conditions. MATERIAL AND METHODS: A retrospective descriptive cross-sectional study was performed. A total of 12,727 clinical records of oral and maxillofacial lesions from four dental services in Brazil were analyzed. Clinical data were collected from the clinical records and evaluated. RESULTS: The series comprised 12 males (52.2%) and 11 females (47.8%), with a mean age of 56.8 ± 14.6 years (ranging: 24-82 years) and a 1.1:1 male-to-female ratio. Most of the lesion s affected the soft palate (n = 15, 65.2%). Clinically, the lesions presented mainly as an asymptomatic (n = 17, 73.9%) blood-filled blister that ruptured after a few minutes or hours, leaving an erosion. The masticatory trauma was the most frequent triggering event. No patient had coagulation disorders. A biopsy was performed in only four cases (17.4%). Treatment was symptomatic with a favorable outcome. CONCLUSIONS: ABH is still poorly documented in the literature, and its etiology remains uncertain. ABH mainly affects the soft palate of elderly adults and has a favorable evolution in a few days. The therapeutic approach is often focused only on the relief of symptoms. However, it can share some clinical features with more serious diseases. Therefore, clinicians must recognize these lesions to avoid misdiagnosis.

Med Oral Patol Oral Cir Bucal. 2021 Sep 25:25040. doi: 10.4317/medoral.25040. Online ahead of print. ABSTRACT BACKGROUND: Oral lichen planus (OLP) is a common, frequently symptomatic, immune-mediated disease. Various treatments have been used for symptomatic OLP, including corticosteroids and immunosuppressants administered topically or systemically. The aim of this study was to compare the effectiveness of topical dexamethasone vs. topical cyclosporine in treatment of symptomatic OLP. MATERIAL AND METHODS: Thirty-two patients with biopsy-proven symptomatic OLP were randomly assigned to two therapeutic groups: dexamethasone 2mg/5ml or cyclosporine 100mg/ml, both administered topically in a swish and spit method three times a day for 4 weeks. The patients were followed up for a total of 6 months. Assessed parameters included clinical scoring (according to Thongprasom's scale, 0-5), pain (VAS scale, 0-10), dysphagia and speech diff iculties (none, mild or severe). Possible side effects, including fungal overgrowth, were also recorded. RESULTS: At the end of the 4-week treatment period, both dexamethasone and cyclosporine showed a statistically significant improvement in clinical scoring (p<0.025 and p=0.034, respectively), which was better with dexamethasone (p=0.001). In addition, both dexamethasone and cyclosporine induced statistical significant improvement in pain and dysphagia (and speech difficulties for dexamethasone), without significant differences between the two groups. Regarding side effects, patients in the dexamethasone group developed candidiasis more frequently compared to cyclosporine (p=0.031). At the end of the 6-month follow-up period, the difference in response between the two groups was not statistically significant. Interestingly, a trend for further improvement compared with the end of the 4-week treatment period was noticed only for patients treated with cyclosporine. CO NCLUSIONS: Despite the small number of enrolled patients, topical cyclosporine treatment induces a significant clinical improvement in symptomatic OLP patients, which, compared to topical dexamethasone, appears to be less pronounced during initial administration, but capable to induce further improvement after discontinuation with a satisfactory long-term remission in the absence of significant side effects. This study may contribute to a better understanding of the differences in effectiveness of OLP topical treatments and guide future larger scale clinical trials.

Perioperative Outcomes of a Hydrocortisone Protocol after Endonasal Surgery for Pituitary Adenoma Resection

xlomafota13 shared this article with you from Inoreader Perioperative Outcomes of a Hydrocortisone Protocol after Endonasal Surgery for Pituitary Adenoma Resection Via Journal of Neurological Surgery Part B: Skull Base J Neurol Surg B Skull Base DOI: 10.1055/s-0041-1735588 Introduction In pituitary adenomas (PAs), the use of postoperative steroid supplementation remains controversial, as it reduces peritumoral edema and sinonasal complaints but disrupts the detection of adrenal insufficiency (AI). It is unclear whether postoperative cortisol supplementation has a measurable effect on improving outcomes in patients with pituitary adenoma undergoing endoscopic transsphenoidal surgery (ETS). The objective of the study was to evaluate a postoperative steroid treatment protocol on various surgical outcomes in patients with PA undergoing ETS. Methods A retrospective cohort study was performed for patients undergoing ETS from 2005 to 2020 for PA at a single tertiary academic center. Patients were divided into two groups: those managed by a routine postoperative glucocorticoid supplementation protocol (steroid protocol) and those who received supplementation based on postoperative cortisol laboratory assessment (steroid sparing protocol). Management was otherwise the same between groups. Evaluation of length of stay (LOS), sinonasal outcomes, 30-day readmission, and perioperative complications, including AI, were performed. Results Among 535 patients, 21% (n = 111) received postoperative steroids, while the remainder (n = 424) did not. There were no differences in mean LOS (3 vs. 3 days, p = 0.72), sinonasal complaints (27 vs. 19%, p = 0.12), 30-day readmission (5% vs. 5%, p = 0.44), and perioperative complications (5 vs. 5%, p = 0.79) between both the groups. A multivariate model supported that both groups were comparable in predicting LOS, 30-day readmission, and complications. No reduction in readmission for AI was seen. Conclusion Routine administration of postoperative glucocorticoids did not significantly improve patient outcomes in patients with PA who underwent ETS.
