The Incidence of Sudden Sensorineural Hearing Loss (SSNHL) in COVID-19 Patients in Tertiary Care Referral Units.

COVID-19 is a new pandemic infectious disease that emerged in Wuhan, China, at the end of 2019. We aimed to evaluate the sudden sensorineural hearing loss (SSNHL) prevalence after COVID-19 infection or even vaccination. This is a two-center retrospective, observational cross-sectional study performed at tertiary care referral Audiovestibular Medicine Units at the period between August 1, 2020, and October 31, 2021.

The role of low levels of vitamin D as a co-factor in the relapse of benign paroxysmal positional vertigo (BPPV).

Background: Benign paroxysmal positional vertigo is characterized as brief episodes of vertigo that are exacerbated by the unexpected act of moving to a current provoking location. It is thought to be an otoconia-related balance disorder. Our objectives were to assess the serum concentrations of vitamin D and calcium (total and ionized) in cases with BPPV, determine if low vitamin D levels were regarded as a cause for BPPV relapse, and determine whether vitamin D supplementation would minimize the risk of BPPV relapse.

Comparing the Diagnostic Accuracy of Clinical and Radiological Measures in Hand Soft-Tissue Masses.

Introduction Imaging modalities are imperative to aid in diagnosing hand soft-tissue tumors. Limited insight is available into the diagnostic accuracy of history and physical examination in comparison to radiological diagnosis.  Methods In this retrospective analysis, data of patients with hand soft-tissue tumors that were surgically treated and diagnosed through biopsy were extracted; taking this as a reference, the sensitivity, specificity and positive and negative predictive values and likelihood ratios of the clinical approach and radiological tools were contrasted against each other.
