Brain perfusion single photon emission computed tomography abnormality in MRI-negative stroke-like patients post COVID-19 vaccination
Stroke-like symptoms after COVID-19 vaccination was thought to be functional if there was no anatomical image abnormality. We aimed to analyze brain perfusion changes in these patients. A case-control study of brain perfusion single photon emission computed tomography (SPECT) of 12 vaccinated patients with left-sided stroke-like symptoms were compared with 12 age- and gender-matched normal interictal brain SPECTs using voxel-based analysis. Significant hyperperfusion was seen on the right side in postcentral, inferior parietal, mid temporal, parahippocampal, and caudate regions, and on the left side in the thalamus, hippoc...

The telemedicine experience: using principles of clinical excellence to identify disparities and optimize care
The use of telemedicine has increased significantly during the Corona virus disease 2019 pandemic. This manuscript serves to identify the underlying principles of clinical excellence in telemedicine and to determine whether effective care practices can be generalized as a one-size-fits-all model or must instead be tailored to individual patient populations. A survey assessing care quality and patient satisfaction for patients using telemedicine was created and administered via email to 2 urban cohorts of varying demographics and socioeconomic backgrounds: a population of patients with prior stroke and cerebrovascular di...

The impact of COVID-19 on home, social, and productivity integration of people with chronic traumatic brain injury or stroke living in the community
Compare community integration of people with stroke or traumatic brain injury (TBI) living in the community before and during the coronavirus severe acute respiratory syndrome coronavirus 2 disease (COVID-19) when stratifying by injury: participants with stroke (G1) and with TBI (G2); by functional independence in activities of daily living: independent (G3) and dependent (G4); by age: participants younger than 54 (G5) and older than 54 (G6); and by gender: female (G7) and male (G8) participants. Prospective observational cohort study In-person follow-up visits (before COVID-19 outbreak) to a rehabilitation hospital ...

Quadrantanopia as the only symptom of post-COVID stroke in the occipital pole: Case report
We report a case of a 46-year-old woman with quadrantanopia due to stroke confirmed with brain MRI, secondary to COVID-19 infection with chronically elevated D-dimers and treated with anticoagulation/antithrombotic modalities. Quadrantanopia was the only symptom recognized by the patient of a stroke localized in the occipital pole of the brain. Diagnosis: The patient was diagnosed with quadrantanopia due to stroke confirmed with brain MRI, secondary to COVID-19 infection. Intervention: Patient underwent ophthalmological examination and MRI. Outcomes: A thrombotic or ischemic risks in the chronic recove...

Effect of the COVID-19 pandemic in stroke code activations in the region of Madrid: A retrospective study
Acute sstroke is the most common time-dependent disease attended in the emergency medical service (EMS) of Madrid (SUMMA 112). Community of Madrid has been one of the most affected regions in Spain by the coronavirus disease 2019 (COVID-19) pandemic. A significant reduction in acute sstroke hospital admissions has been reported during the COVID-19 pandemic compared to the same period 1 year before. As international clinical practice guidelines support those patients with suspected acute stroke should be accessed via EMS, it is important to know whether the pandemic has jeopardized urgent pre-hospital stroke care, the first...

Pathogeny of cerebral venous thrombosis in SARS-Cov-2 infection: Case reports
We describe 2 cases of women admitted during the spring of 2020 for intracranial hypertension signs, in stroke units in Great-east, a French area particularly affected by COVID-19 pandemia. Diagnoses: Cerebral imaging revealed extended CVT in both cases. The first case described was more serious due to right supratentorial venous infarction with hemorrhagic transformation leading to herniation. Both patients presented typical pneumonia due to SARS-Cov-2 infection, confirmed by reverse transcription polymerase chain reaction on a nasopharyngeal swab in only one. Interventions: The first patient had to undergo ...

Simultaneous cardio-cerebral infarction in the coronavirus disease pandemic era: A case series
Conclusion: Early recognition and immediate treatment is important in different scenarios leading to thrombosis as the outcome. Additionally, addressing the unknown risks that could contribute to our traditional understanding of these causative mechanisms is important. The hypothesis of exacerbated damage caused by inflammatory and immunological endothelial systemic damage should further be explored to be able to delineate new possibilities in managing these conditions.

Significant reduction in the visits to the emergency room department during the COVID-19 pandemic in a tertiary hospital in Greece: Indirect victims of the pandemic?
COVID-19 pandemic caused a major crisis, affecting and straining health care systems, including some very advanced ones. The pandemic may have also indirectly affected access to health care for patients with other conditions, not related to COVID-19, even in countries not overwhelmed by an outbreak. We analyzed and compared visits to the emergency room (ER) department during the same calendar period of 2019 and 2020 (from March 1 to March 31 of each year) in our hospital, a medium size, tertiary center, located in the center of Athens, which is not a referral center for COVID-19. Total ER visits were reduced by 42.3%...

The epidemiological characteristics of 2019 novel coronavirus diseases (COVID-19) in Jingmen, Hubei, China
In conclusion, all people are susceptible to COVID-19, and older males and those with comorbid conditions are more likely to become severe cases. Even though COVID-19 is highly contagious, control measures have proven to be very effective, particularly wearing masks, which could prevent most infections.
