SARS-CoV-2 Impairs Vision.

Objectives: Affection of the central nervous system and the eyes is increasingly recognized as manifestations of a SARS-CoV-2 infection (COVID-19). This review aims at summarizing and discussing recent advances concerning causes and locations of impaired vision because of an infection with SARS-CoV-2.

Methods: On a literature search through PubMed and ScholarOne, all available publications about COVID-19 patients with impaired vision were retrieved.

Cardioprotection stimulated by resveratrol and grape products prevents lethal cardiac arrhythmias in an animal model of ischemia and reperfusion.

Purpose: To evaluate the preventive cardioprotective effects of resveratrol and grape products, such as grape juice and red wine, in animal model of cardiac ischemia and reperfusion.

Methods: Male Wistar rats orally pretreated for 21-days with resveratrol and grape products were anesthetized and placed on mechanical ventilation to surgically induce cardiac ischemia and reperfusion by obstruction (ischemia) followed by liberation (reperfusion) of blood circulation in left descending coronary artery. These rats were submitted to the electrocardiogram (ECG) analysis to evaluate the effects of pretreatment with resveratrol and grape products on the incidence of ventricular arrhythmias (VA), atrioventricular block (AVB) and lethality (LET) resulting from cardiac ischemia and reperfusion.

Guillain-Barre syndrome in 220 patients with COVID-19.

This review summarises and discusses recent findings concerning the pathophysiology, clinical presentation, diagnosis, treatment, and outcome of SARS-CoV-2-associated Guillain-Barre syndrome (SC2-GBS). By the end of December 2020, at least 220 patients with SC2-GBS have been published in 95 papers. SC2-GBS is most likely secondary due to an immune reaction against SARS-CoV-2 since the virus has not been found in the CSF of any SC2-GBS patient so far reported.

Clinical and Pathophysiologic Spectrum of Neuro-COVID.

Though the lungs are predominantly affected in SARS-CoV-2-infected patients, extra-pulmonary manifestations can occur. Extra-pulmonary manifestations of the central and peripheral nervous system need to be recognised as they can strongly determine the outcome. This mini-review summarises and discusses previous and recent findings about neuro-COVID.

Left Hemisphere Lateralization of Epileptic Focus Can Be More Frequent in Temporal Lobe Epilepsy Surgical Patients with No Consensus Associated with Depression Lateralization.

Temporal lobe epilepsy (TLE) is considered to be the most common form of epilepsy, and it has been seen that most patients are refractory to antiepileptic drugs. A strong association of this ailment has been established with psychiatric comorbidities, primarily mood and anxiety disorders. The side of epileptogenic may contribute to depressive and anxiety symptoms; thus, in this study, we performed a systematic review to evaluate the prevalence of depression in TLE in surgical patients.

Vascular Damage May Mimic Retinitis and Optic Neuritis in COVID-19.

Ophthalmologic nvolvement in SARS-CoV-infected patients is variegated. One of the ophthalmologic pathologies is optic neuritis. Optic neuritis in SARS-CoV-infected patients may precede the classical pulmonary manifestations of COVID-19 and can be unilateral or bilateral.
