Hearing loss and COVID-19: an umbrella review.

INTRODUCTION: COVID-19 can result in an extensive range of extrapulmonary, and neurological signs and symptoms such as olfactory and/or taste dysfunction, and otologic symptoms. The aim of this study was to investigate the hearing loss manifestation from COVID-19. METHODS: The goal of this umbrella review was to examine hearing loss associated with COVID-19 disease. English literature published until October 15, 2022 in online databases including PubMed, Scopus, Web of Science, and Embase was considered for this purpose. Eligibility of the articles for subsequent data extraction was evaluated in a two-step selection process with consideration to an inclusion/exclusion criterion. This review followed the PRISMA protocol and the Amstar-2 checklist for quality assessment. RESULTS: A total of four treatment strategies were used by different studies which included oral corticosteroids, intratympanic corticosteroids, combined oral and intratympanic corticosteroids, and hyperbaric oxygen therapy. Five studies investigated corticosteroid use in the forms of oral or intratympanic injection; four studies reported (complete or partial) hearing improvements after steroid treatment, while one study stated no significant improvement in hearing function. One study reported that oral corticosteroid monotherapy alone was not effective, while vestibular symptoms were ameliorated by a combination of oral prednisone, intratympanic dexamethasone injection, and hydroxychloroquine. CONCLUSION: The findings suggest that despite being one of the rare complications of COVID-19, hearing loss can impact a patient's quality of life. The most common type reported was sensorineural hearing loss, which can be diagnosed with variable techniques.

COVID-19 Treatment Success After Repeat Courses of Azithromycin: A Report of Three Cases.

BACKGROUND: Azithromycin has been considered as a possible therapeutic agent for COVID-19 patients. However, there is limited data on its efficacy. CASE PRESENTATION: We describe three patients diagnosed with COVID-19 who did not respond to the initial treatment but improved dramatically upon adding azithromycin with a successful outcome. CONCLUSION: We have presented evidence of the potential beneficial effect of the azithromycin in the treatment of patients with COVID-19 in three different clinical settings. More evidence is needed regarding the microbiological data, safety, and efficacy of this medication in the management of COVID-19.

A systematic review of ECG findings in patients with COVID-19.

INTRODUCTION: Since the epidemic of COVID-19 attracted the attention, reports were surrounding electrocardiographic changes in the infected individuals. We aimed at pinpointing different observed ECG findings and discussing their clinical significance. METHODS: We conducted a systematic search in PubMed, Embase, and Scopus databases. We included eligible original papers, reports, letters to the editors, and case reports published from December 2019 to May 10, 2020. RESULTS: The team identified 20 articles related to this topic. We divided them into articles discussing drug-induced and non-drug-induced changes. Studies reported an increased risk of QTc interval prolongations influenced by different therapies based on chloroquine, hydroxychloroquine, and azithromycin. Although these medications increased risks of severe QTc prolongations, they induced no arrhythmia-related deaths. In the non-drug-induced group, ST-T abnormalities, notably ST elevation, accounted for the most observed ECG finding in the patients with COVID-19, but their relation with myocardial injuries was under dispute. CONCLUSION: This systematic review suggests that identifying ECG patterns that might be related to COVID-19 is vital. Provided that physicians do not recognize these patterns, they might erroneously risk the lives of their patients. Furthermore, important drug-induced ECG changes provide awareness to the health-care workers on the risks of possible therapies.

Postoperative COVID-19 Pneumonia in an Asymptomatic Patient: A Case Report.

BACKGROUND: The recent outbreak of the coronavirus disease (COVID-19) in China has rapidly spread throughout the world and there are many reports of symptoms ranging from malaise to acute respiratory distress syndrome (ARDS) caused by this infection. However, few reports have been discussed surgical outcomes in COVID-19 patients. CASE PRESENTATION: In this report, we described a case of an elderly female developed with postoperative pulmonary complications after uneventful elective minor surgery. The patient was asymptomatic before the operation with no history of cough or fever. After surgery, the patient developed respiratory distress and chest radiological imaging revealed bilateral ground-glass opacities. It seems any type of surgeries requiring local anesthesia or general anesthesia may contribute to worsening outcomes in patients with covid19.

Predictors of mortality in patients with COVID-19-a systematic review.

INTRODUCTION: In the current COVID-19 pandemic, disease diagnosis is essential for optimal management and timely isolation of infected cases in order to prevent further spread. The aim of this study was to systematically review the assessment of risk and model the predictors of mortality in COVID-19 patients. METHODS: A systematic search was conducted of PubMed, Scopus, Embase, Google Scholar, and Web of Science databases. Variables associated with hospital mortality using bivariate analysis were included as potential independent predictors associated with mortality at the p < 0.05 levels. RESULTS: We included 114 studies accounting for 310,494 patients from various parts of the world. For the purpose of this analysis, we set a cutoff point of 10% for the mortality percentages. High mortality rates were defined as higher than 10% of confirmed positive cases and were given a score of two, while low mortality (<10%) was assigned the score of one. We then analyzed the associations between 72 variables and the observed mortality rates. These variables included a large range of related variables such as demographics, signs and symptoms and related morbidities, vital signs, laboratory findings, imaging studies, underlying diseases, and the status of countries' income, based on the United Nation's classifications. CONCLUSION: Findings suggest that older age, hypertension, and diabetes mellitus conferred a significant increased risk of mortality among patients with COVID-19. In the multivariate analysis, only diabetes mellitus demonstrated an independent relationship with increased mortality. Further studies are needed to ascertain the relationship between possible risk factors with COVID-19 mortality.
