Immunotherapy for arterial ischaemic stroke in childhood: a systematic review
Conclusions
Immunotherapies are used in children with AIS, mainly as steroids for children with arteriopathy. However, there is currently little robust evidence to either encourage or discourage this practice. There is weak evidence consistent with the hypothesis that in certain children at risk, steroids may both reduce the risk of occurrent/recurrent stroke and enhance neurological outcomes. As the potential benefit is still uncertain, this indicates that a trial of steroids in childhood AIS may be justified.

Stroke in patients with tuberculous meningitis in a low TB endemic country: an increasing medical emergency?
This study evaluated the frequency, clinical characteristics, risk factors and outcomes of patients with TBM complicated by stroke admitted to the Infectious Disease Clinic, University of Perugia Hospital, Italy from 1971 to 2010. Over four decades, 419 patients were admitted with tuberculosis, of these 30 (7.1%) were diagnosed with TBM: 20 definite, one probable and nine possible. Twenty-six were evaluable for stroke and six (23%) had stroke. The latter six had advanced stages of meningitis, two tested HIV positive, three HIV negative and in one HIV was not performed. Of seven patients without stroke tested for HIV, only ...

Potential association between bacterial infections and ischemic stroke based on fifty case-control studies: A systematic review and meta-analysis
CONCLUSIONS: In this meta-analysis, a significant relationship was observed between infection by three bacteria such as C. pneumoniae, H. pylori, and M. tuberculosis with the occurrence of ischemic stroke. Furthermore, due to the similarity between TLRVYK domain in β2-glycoprotein-I and TLRVYK peptide in various of microorganisms, produced antibodies against pathogens interact with β2-glycoprotein-I, hence the cross-reaction phenomenon increases the positive relationship between infectious diseases and ischemic stroke.PMID:35592534 | PMC:PMC9112101 | DOI:10.1016/j.nmni.2022.100980

A reversible stroke-like splenial lesion in viral encephalopathy.
CONCLUSION: Our case confirmed with previous findings that a reversible stroke-like splenial lesion could be seen in virus related encephalopathy and regarded as a good prognosis marker. Transient intramyelinic edema or inflammatory infiltrate is the possible mechanism and further studies enrolling more related cases will be needed to confirm our finding.

Infectious Etiologies of Stroke
Semin Neurol 2019; 39: 482-494 DOI: 10.1055/s-0039-1687915Central nervous system (CNS) infections are a frequently underappreciated potential etiology of cerebrovascular disease. Highlighted in this review are a selection of infectious agents that lead to cerebrovascular complications through various mechanisms including multifocal vasculopathy, focal infiltrative vasculitis and vasospasm, and direct vessel wall invasion and thrombus formation. Diagnosis of stroke due to underlying CNS infection requires a high index of clinical suspicion and careful consideration of neuroimaging, serum, and cerebrospinal fluid studies in ...

The role of 3-ketosteroid 1(2)-dehydrogenase in the pathogenicity of Mycobacterium tuberculosis
Conclusions:
The Mtb mutant DeltakstD strain, which is unable to use cholesterol as a source of carbon and energy, has a limited ability to multiply in resting M[latin capital letter o with stroke] following infection, reflecting a failure of the DeltakstD strain to inhibit the TLR2-dependent bactericidal activity of resting M[latin capital letter o with stroke].

Central Nervous System involvement in tuberculosis: an MRI study considering differences between patients with and without Human Immunodeficiency Virus 1 infection
Conclusions Stroke involving the basal ganglia best differentiates CNSTB patients who are HIV+ from those HIV-. This finding was not correlated with meningeal enhancement suggesting that small arteries involvement might precede it. Therefore, we think that HIV+ patients with a new onset of stroke should be evaluated for CNSTB. Follow-up MRI should also be planned since meningeal enhancement might appear in later stages of the disease.

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...

A Case Report of Rheumatoid Meningitis, an unusual complication of Rheumatoid Arthritis (P4.056)
CONCLUSIONS: Rheumatoid Meningitis is an extremely uncommon complication of Rheumatoid Arthritis. Initial presentations can vary from altered mental status (most common), cranial neuropathies, hemiparesis/paraparesis, seizure, headache and very rarely stroke like symptoms. This patient with Rheumatoid Arthritis presented with multiple stroke like episodes, lepomeningeal enhancement. Diagnosis was established on the basis of Imaging and Histopathology after excluding other potential causes of granulomatous meningitis.

Anti-inflammatory drug may help prevent heart attacks
Conclusion
This well-conducted study shows promising signs that canakinumab may reduce the risk of future heart attacks and other cardiovascular events in people who've had them in the past.
But before any changes are made to the current licensing of this drug, further research is needed to confirm the beneficial effects and the optimal dose.
Most importantly, researchers will need to focus on the observation that the drug lowered white blood cell counts and increased the risk of fatal infection.
They estimated around 1 in every 300 people taking canakinumab would die of a fatal infection. This number, while low, is sti...

Stem Cells for Cell-Based Therapies
The world of stem cells
We know the human body comprises many cell types (e.g., blood cells, skin cells, cervical cells), but we often forget to appreciate that all of these different cell types arose from a single cell—the fertilized egg. A host of sequential, awe-inspiring events occur between the fertilization of an egg and the formation of a new individual:
Embryonic stem (ES) cells are also called totipotent cells.
The first steps involve making more cells by simple cell division: one cell becomes two cells; two cells become four cells, etc.
Each cell of early development is undifferentiated; that is, it is...
