Ipsilateral Vocal Cord Paralysis After Acute Anterior Ischemic Stroke
CONCLUSION: Our case is a rare case of transient ipsilateral vocal cord paralysis associated with anterior unilateral cerebral ischemia. The paralysis resolved with improvement of the cerebral ischemic penumbra.PMID:33635769 | DOI:10.7812/TPP/20.104

Potential Applications of Remote Limb Ischemic Conditioning for Chronic Cerebral Circulation Insufficiency
Conclusion
Due to its long-term and often invisible course, CCCI has received less attention than acute cerebral ischemic stroke. However, without appropriate intervention, CCCI may lead to a variety of adverse events. Because the pathophysiological changes associated with CCCI are complex, pharmacological research in this area has been disappointing. Recent research suggests that RLIC, which is less invasive and more well-tolerated than drug treatment, can activate endogenous protective mechanisms during CCCI. In the present report, we reviewed studies related to CCCI (Table 1), as well as those related to stroke and sta...

Characterizing the Penumbras of White Matter Hyperintensities and Their Associations With Cognitive Function in Patients With Subcortical Vascular Mild Cognitive Impairment
Conclusion
In this study, reduced CBF and FA and increased MD in the inner NAWM layers for both PVWMH and DWMH suggested extensive WM alterations beyond the visible WM lesions commonly observed on clinical MRI of svMCI subjects. CBF penumbras cover more extensive WM at risk than DTI penumbras, suggesting the likelihood that compromised CBF precedes white matter integrity changes, and CBF penumbras may be a potential target for the prevention of further microstructural white matter damage. The imaging parameters investigated, however, did not correlate to cognition.

Hypertension - human studies
Conclusions:Higher predialysis SBP variability is associated with stroke on HD populations suggesting a potential role for cerebral perfusion instability. We confirm known associations between age, diabetes, pre-existent cerebrovascular disease and hypertension. In contrast to studies in non-dialysis patients we do not find an association between EPO dose and stroke. Interventional trials of blood pressure management on stroke are recommended.

A Case of Transient Global Amnesia: A Review and How It May Shed Further Insight into the Neurobiology of Delusions
Conclusion
In closing, our patient’s episode of TGA combined with her emotional and perceptual response lends credence to the proposal of a “fear/paranoia” circuit in the genesis of paranoid delusions—a circuit incorporating amygdala, frontal, and parietal cortices. Here, neutral or irrelevant stimuli, thoughts, and percepts come to engender fear and anxiety, while dysfunction in frontoparietal circuitry engenders inappropriate social predictions and maladaptive inferences about the intentions of others.[54]

Increased arterial pulsatility and progression of single subcortical infarction
ConclusionsHigher pulsatility was associated with progression in lacunar infarction. PI measured by transcranial Doppler sonography might reflect downstream arterial resistance and vascular/paravascular perfusion status and be a possible indicator of stroke progression.Key Points•Higher pulsatility index was observed in progression group of lacunar infarction patients.•Higher pulsatility index seemed to be associated with progression in lacunar infarction patients.•Differences in the factors associated with stroke progression suggest different underlying pathophysiologies.

A Serious Diagnosis Lacking Common Symptoms
BY JENNIFER TUONG; IVAN KHARCHENKO; JEAN LUC AGARD; & AHMED RAZIUDDIN, MDA 65-year-old man who had HIV well-controlled with highly active antiretroviral therapy, hypertension, sciatica, and restless leg syndrome presented to the emergency department with left leg pain. He also had had chemotherapy and radiation for anal cancer. The patient said the pain had started 45 minutes earlier when he was sitting on the toilet.He described the pain as sore in quality and 10/10 on the pain scale. He reported that it had started in his lower back and radiated to his left leg. He said he had had no trauma or weakness to the regi...

Evidence for Cerebral Hemodynamic Measurement-based Therapy in Symptomatic Major Cerebral Artery Disease.
Authors: Yamauchi H
Abstract
In patients with atherosclerotic internal carotid artery or middle cerebral artery occlusive disease, chronic reduction in cerebral perfusion pressure (chronic hemodynamic compromise) increases the risk of ischemic stroke and can be detected by directly measuring hemodynamic parameters. However, strategies for selecting treatments based on hemodynamic measurements have not been clearly established. Bypass surgery has been proven to improve hemodynamic compromise. However, the benefit of bypass surgery for reducing the stroke risk in patients with hemodynamic compromise is controversial....

Ditch the Machine to Improve Accuracy in Blood Pressure Measurement and Diagnostics
Conclusion
For the patient in this case, the decision to forego the convenience of a machine in favor of the skills of a knowledgeable paramedic was lifesaving. Much like the comparison often drawn between the old-fashioned barbell and more sophisticated exercise machines, newer, more complex, and more expensive might make a process more comfortable, but doesn’t always equate to superior results.
As we surrender more and more of our hands-on skills to the ease of automated technology, we risk more than the loss of the aptitudes that form the foundation of sound patient assessment—we place our patients in jeopardy of mi...

Sex-Related Differences in Patients Undergoing Thoracic Aortic Surgery: Evidence from the Canadian Thoracic Aortic Collaborative.
CONCLUSIONS: Women experience worse outcomes following thoracic aortic surgery with hypothermic circulatory arrest. Further investigation is required to better delineate which measures may reduce sex-related outcome differences following complex aortic surgery.

Combined brain/heart magnetic resonance imaging in antiphospholipid syndrome-two sides of the same coin
AbstractAntiphospholipid syndrome (APS) is an autoimmune disorder characterized by arterial, venous, and/or small vessel thrombosis, pregnancy morbidity, and persistently elevated levels of antiphospholipid antibodies (aPL). Cardiovascular disease (CVD) in APS can present as heart valvular disease (HVD), macro-micro-coronary artery disease (CAD), myocardial dysfunction, cardiac thrombi, or pulmonary hypertension. Brain disease presents as stroke or transient ischemic attack (TIA) and less frequently as cerebral venous thrombosis, seizures, cognitive dysfunction, multiple sclerosis (MS) −like syndrome, or chorea. Infarcts...

Branch-first continuous perfusion aortic arch replacement. Insight into our results
CONCLUSIONS: BF-CPAR is safe and adds to the armamentarium of Aortic Arch Repair. In elective and uncomplicated acute-dissection cases, it has no mortality and low stroke (1.9%), and vital organ dysfunction risk. Its results which are comparable to many of the best currently reported series, is driven by avoidance of cerebral circulatory arrest and reduction of cardiac and visceral ischemic time.PMID:35238522 | DOI:10.23736/S0021-9509.22.12272-X
