ABSTRACT

Lingual thyroid is an uncommon condition and cases accompanying thyroid hemiagenesis are rarely documented. Patients with thyroid hemiagenesis are usually asymptomatic and generally diagnosed incidentally. Herein, we reported the case of thyroid hemiagenesis accompanying an ectopic lingual thyroid with euthyroidism and presented with regional symptoms.

Background

The entity assignment of salivary gland tumors (SGT) based on histomorphology can be challenging. Raman spectroscopy has been applied to analyze differences in the molecular composition of tissues. The aim of this study was to evaluate the suitability of RS for entity assignment in SGT.

Methods

Raman data were collected in deparaffinized sections of pleomorphic adenomas (PA) and adenoid cystic carcinomas (ACC). Multivariate data and chemometric analysis were completed using the Unscrambler software.

Results

The Raman spectra detected in ACC samples were mostly assigned to nucleic acids, lipids, and amides. In a principal component-based linear discriminant analysis (LDA) 18 of 20 tumor samples were classified correctly.

Conclusion

In this proof of concept study, we show that a reliable SGT diagnosis based on LDA algorithm appears possible, despite variations in the entity-specific mean spectra. However, a standardized workflow for tissue sample prep aration, measurement setup, and chemometric algorithms is essential to get reliable results.

Susac Syndrome: A Rare cause of Bilateral Sensorineural hearing loss from North India—A Case Report with Review of literature

xlomafota13 shared this article with you from Inoreader

Abstract

Susac Syndrome (SS) is a rare unique autoimmune underdiagnosed disorder characterized by the clinical triad of central nervous system (CNS) dysfunction, sensorineural hearing impairment, and branch retinal artery occlusion (BRAO). Objectives The purpose of reporting the case is to succinctly highlight this enigmatic condition with focus on otological and audiological aspect of SS and also to augment awareness of this disease among otolaryngologists neurologists, psychiatrists and ophthalmologists. Additionally we reviewed the otological menifestations and audiological findings related to SS. Methods A case of 38 year old female is presented with bilateral SNHL as the initial symptom of SS. The review of otological and audiological findings of previous 10 year case reports was executed using the PRISMA protocol on 20 cases. Results It was seen that inspite of the ear being one of the main organs involved in the SS very few had undergone detailed audiological assessment. Our review of literature showed that only 40% cases had done audiological assessment other than PTA, out of which only 5% had undergone complete audiological workup. 30% of the patients were having auditory symptoms as presenting chief complaint. Conclusion Otolyryngologists should keep SS in differentials when a case of SNHL of unknown etiology is encountered.We emphasize the use newer noninvasive Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation diagnostic tools like Optical coherence tomography (OCT), MRI and detailed audiological tests for timely diagnosis of SS. Further multidisciplinary assessment protocols should be used to prevent the development of severe sequelae.

Age Related Immunosenescence Epstein-Barr Virus-positive Mucocutaneous Ulcer of the Palate Mimicking Medication-related Osteonecrosis of the Jaw

xlomafota13 shared this article with you from Inoreader

Abstract

Epstein-Barr virus (EBV) -positive mucocutaneous ulcer (EBVMCU) was first described as a lymphoproliferative disorder in 2010. In recent years, EBVMCU has been reported in the field of oral surgery. On the other hand, medication-related osteonecrosis of the jaw (MRONJ) is an osteomyelitis that occurs in patients receiving antiresorptive agents including bisphosphonates (BP) and/or denosumab developing with bacterial infections such as dental diseases and mucositis. MRONJ caused by EBVMCU in the elderly has not been reported. Here, we report a rare case of MRONJ caused by EBVMCU in the elderly. The patient, an 82-year-old woman, had received BP for more than 2 years. An ulcerative lesion was found in the palatal mucosa; biopsy performed from the site confirmed the diagnosis of EBVMCU. At follow-up, the lesion disappeared spontaneously. At the 6-month follow-up, bone formation was observed at the site of the lesion, and the sequestrum was removed. At the 12-mo nth follow-up healing of the EBVMCU region was seen indicating a good prognosis.

Current and Emerging Medical Therapies for Dizziness

xlomafota13 shared this article with you from Inoreader
Medical therapies for dizziness are aimed at vertigo reduction, secondary symptom management, or the root cause of the pathologic process. Acute peripheral vertigo pharmacotherapies include antihistamines, calcium channel blockers, and benzodiazepines. Prophylactic pharmacotherapies vary between causes. For Meniere disease, betahistine and diuretics remain initial first-line oral options, whereas intratympanic steroids and intratympanic gentamicin are reserved for uncontrolled symptoms. For cerebellar dizziness and oculomotor disorders, 4-aminopyridine may provide benefit. For vestibular migraine, persistent postural perceptual dizziness and mal de débarquement, treatment options overlap and include selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, tricyclic antidepressants and calcium channel blockers.
