Pneumomediastinum and Pneumopericardium as Uncommon Complications of COVID-19 Infection: A Review Article.

There is an emerging body of literature describing an increasing incidence of pneumomediastinum and, to a lesser extent, pneumopericardium as a complication of COVID-19. However, the literature lacks information regarding patients' characteristics and a general view of this unusual condition. The purpose of this paper is to summarize the current literature on this phenomenon. In this study, we summarize the risk factors/etiology, imaging modalities, management, and prognosis of known cases in the literature. In total, 48 articles were included in the study, ranging from case reports to case series. Most patients were male (83.3%). The overall mortality rate was 27.1% and the recovery rate was 62.5%.

Persistent Parosmia Caused By COVID-19 Infection: An Emerging Symptom.

Objectives Coronavirus disease 2019 (COVID-19) is associated with several known signs and symptoms, including olfactory disturbances leading to anosmia and parosmia. This study aimed to evaluate the clinical features of the emerging symptoms of post-COVID-19 parosmia and to report the outcome of commonly used intervention methods. Methods The study's sample included post-COVID-19 patients who complained of parosmia, presented to otorhinolaryngology clinics at private tertiary care hospitals from December 2020 to April 2021. Patients' data were collected from the hospital system and through direct phone interviews. The Modified Arabic 20-Items Sino-Nasal Outcome Test (MA-SNOT-20) was used to measure the severity of rhinosinusitis symptoms. Results Twenty-one patients were included in the study, and their ages mainly ranged between 20 and 39 years (76.2%), predominantly females 19 (90.5%). Post the COVID-19 illness course, nearly half of the patients (9; 42.9%) reported full recovery of olfaction and taste senses. Nine cases (42.9%) received treatment with intranasal and oral steroids, of which only three cases (14.3%) noticed improvement. The remaining 12 cases (57.1%) did not receive any treatment, two of which improved (9.5%). The maximum MA-SNOT score was 37 while the minimum was 3, and eight patients (38.1%) scores were between one and 10 points. Conclusion Olfactory and taste dysfunctions are common symptoms of COVID-19. The emerging symptom of parosmia is worth reporting in the literature to increase the awareness of this particular symptom in this pandemic era. Many management strategies have been introduced that might be effective. However, further studies are needed to establish evidence-based management protocols.

Neurological Symptoms and Complications of COVID-19 Among Patients in a Tertiary Hospital in Saudi Arabia.

Objectives In this study, we aimed to determine the frequency of neurological signs, symptoms, and complications in coronavirus disease 2019 (COVID-19) patients. We also sought to explore the general characteristics of stroke patients in particular. Methods A retrospective cohort study was conducted among COVID-19 patients who were hospitalized between April-September 2020 at the Al-Noor Specialist Hospital in Makkah city, Saudi Arabia. The study included patients who were aged ≥18 years and presented with or were reported to have any neurological manifestations and/or complications secondary to COVID-19 infection. Results A total of 79 patients were included. The mean age of the cohort was 63.6 years, with a significant male predominance (67.1%). The most commonly reported neurological signs and symptoms were altered level of consciousness (45.9%), dizziness (11.5%), and focal neurological deficit (10.4%). Acute ischemic stroke was seen in 18 patients. Most of them were males (66.7%). Most strokes were in the right middle cerebral artery territory (MCA) (50.0%). Diabetic patients were four times more at risk to develop stroke [odds ratio (OR)=3.76; 95% confidence interval (CI): 1.1-29.9]. Patients with respiratory failure were 21 times more likely to have a stroke (OR=21.3; 95% CI: 2.2-54.6). Patients with acute respiratory distress syndrome recorded a three-fold increased risk for developing stroke (OR=2.96; 95% CI: 1.25-37.3). Critically ill patients had double the risk of stroke (OR=1.8; 95% CI: 1.1-6.9). Other neurological complications were hemorrhagic stroke (3.3%), subacute/chronic infarction (23.3%), meningitis (10%), and brain mass lesion (3.3%). Conclusions Neurological symptoms and complications are not uncommon among COVID-19 patients. Most of these patients had poor outcomes. Acute ischemic stroke was the most common finding on neuroimaging.
