The dominant deformation mode for the anisotropic Ti-6Al-4V columnar structure is basal slip, and that for the isotropic Ti-6Al-4V columnar structure is pyramidal slip. The difference may be important for determining the fatigue behaviour.

Patients undergoing cardiopulmonary stabilization in the intensive care unit for novel coronavirus (COVID-19) are often sedated, placing timely assessment of a neurological decline at risk.

Here, we present two cases of COVID-19 infected young patients transferred to our facility in a cardio-pulmonary crisis, with a poor neurological exam. While there was significant delay in obtaining brain imaging in the first patient, the second patient had timely recognition of her ischemic infarct, underwent emergent surgery, and is now doing well.

These cases highlight the importance of early head imaging in COVID-19 patients with a poor neurological exam. While lungs remain the primary target of COVID-19, these cases alert the medical community to suspect involvement of the central nervous system, since there may be life-saving surgical interventions available.

Neurological manifestations including headache are increasingly described. However, headache as the sole presenting symptom of COVID-19 pneumonia has not been reported. We describe a patient in Tanzania who experienced severe headache for seven days before the onset of other symptoms of COVID-19 that led to her isolation, diagnosis, and treatment.

This report and literature review describes a case of a COVID-19 patient who suffered a cerebellar stroke requiring neurosurgical decompression. This is the first reported case of a sub-occipital craniectomy with brain biopsy in a COVID-19 patient showing leptomeningeal venous intimal inflammation.

The patient is a 48-year-old SARS-COV-2 positive male with multiple comorbidities, who presented with fevers and respiratory symptoms, and imaging consistent with multifocal pneumonia. On day 5 of admission, the patient had sudden change in mental status, increased C-Reactive Protein, ferritin and elevated Interleukin-6 levels. Head CT showed cerebral infarction from vertebral artery occlusion. Given subsequent rapid neurologic decline from cerebellar swelling and mass effect on his brainstem emergent neurosurgical intervention was performed. Brain biopsy found a vein with small organizing thrombus adjacent to focally proliferative intima with focal intimal neutrophils.

A young man with COVID-19 and suspected immune dysregulation, complicated by a large cerebrovascular ischemic stroke secondary to vertebral artery thrombosis requiring emergent neurosurgical intervention for decompression with improved neurological outcomes. Brain biopsy was suggestive of inflammation from thrombosed vessel, and neutrophilic infiltration of cerebellar tissue.

The aim of this study is to present our suggestions for organization, personal protective equipment (PPE) use, work flow of the operating theater, and the treatment of patients with COVID-19 and co-existing neurological disease.

We present the case of a 70-year-old male who was transferred to our Department because of subarachnoid hemorrhage with ruptured right middle cerebral artery aneurysm and SARS CoV-2 infection. The emergency clipping of the aneurysm and hematoma evacuation was performed. According to the therapeutic committee guidelines, chloroquine was started for COVID-19 treatment.

Postoperatively, the patient is in good condition, with the Glasgow Coma Scale (GCS) score of 15, with mild, left hemiparesis, 4+/5 points on the Lovett scale, without symptoms of acute respiratory distress syndrome (ARDS). No one from the stuff was infected during the treatment.

Managing patients with infectious diseases such as COVID-19 presents many challenges and risks for healthcare personnel. Our experience suggests that by following strict safety protocols of PPE use, donning and doffing, and reducing operation time, the surgery may be safe for both the healthcare personnel and the patient.

While secondary brain injury from the systemic manifestations of the disease account for the majority of non-specific neurological symptoms that include headache, nausea, and progressive confusion, the question that remains unanswered is does the nCOVID-19 virus use the olfactory mucosa as a portal to directly invade the brain? A second question is how common does direct CNS invasion complicate the classical cardiorespiratory severe form of the disease? We know from previous studies that almost all members of the Corona virus family have neurotropism. We also know from the current pandemic that deteriorating consciousness and cerebrovascular accidents are not uncommon. read more Several previous scattered case reports, and post-mortem examinations of brain tissue, demonstrated nCOVID-19 nucleic acid in the CSF, and brain tissue, of infected and deceased individuals. We performed a PubMed review of the literature to specifically assess the evidence for the direct CNS invasion by the nCOVID-19 virus.
