Expression of Tie2 (angiopoietin receptor) on the monocyte subpopulations from ischemic stroke patients: Histological and flowcytometric studies
CONCLUSIONS: The results of this study demonstrate dysregulation of angiogenesis in monocyte subsets in ischemic stroke patients, which could be used as an early diagnostic marker of neurovascular damage and may need angiogenic therapy or improved medications to prevent further damage of blood vessels.PMID:36876965 | DOI:10.14670/HH-18-601

Hemophagocytic lymphohistiocytosis diagnosed by bone marrow trephine biopsy in living post-COVID-19 patients: case report and mini-review
AbstractHemophagocytic lymphohistiocytosis (HLH) constitutes a life-threatening inflammatory syndrome. Postmortem histological findings of bone marrow (BM) from COVID-19 patients showed histiocytosis and hemophagocytosis and supported the hypothesis that secondary HLH (sHLH) may be triggered by SARS-CoV-2 infection. However, there are a limited number of sHLH cases in which trephine has been performed in living post-COVID-19 patients. Here we present a recent case and a mini-review of sHLH diagnosed by trephine biopsy in living patients after COVID-19. An 81-year-old man with a past medical history of hypertension, diabete...

A Rare Case of Bilateral Vertebral Artery Dissection Associated with Essential Thrombocythemia
J Neurol Surg A Cent Eur Neurosurg DOI: 10.1055/s-0039-1691754A young patient presented to our hospital with ischemic stroke. She underwent a routine blood test, head computed tomography (CT), brain magnetic resonance imaging, a bone marrow biopsy, and CT angiography. Her diagnosis was a bilateral vertebral artery dissection associated with essential thrombocythemia (ET). She was treated with antiplatelet therapy and a stent implantation. The association of bilateral vertebral artery dissection with ET is rare. An early diagnosis and timely management is key to the best outcome. [...] Georg Thieme Verlag KG Stuttgart · Ne...

Using Dental Pulp Stem Cells for Stroke Therapy
Conclusion and Future Perspectives Stem cell-based therapy is a promising alternative for stroke treatment. While stem cells from different sources, including induced PSC, ESC, MSC, and NSC, have been investigated, using NSC and enhancing the natural mechanisms is most appropriate for brain repair. In preclinical models of stroke, stem cell transplantation has led to positive outcomes through a variety of cellular and molecular mechanisms, many being mediated by the array of beneficial factors produced by the cells. Recent advances in cellular reprogramming have provided alternative sources of NSC to be investigated, allo...

Acute Ischemic Stroke as a Presenting Feature of Multiple Myeloma (P3.279)
Conclusions:Stroke is a leading and preventable cause of disability in the US adult population. The majority of strokes are due to atherosclerotic vascular or cardioembolic disease. Understanding the diagnostic work up of stroke and recognizing rare etiologies like MM is important for stroke prevention. This brings to light the importance of recognizing stroke as an initial presenting feature of multiple myeloma and of multiple myeloma as an important treatable etiology of stroke.Disclosure: Dr. Chung has nothing to disclose.

Progressive multifocal leukoencephalopathy during fumarate monotherapy of psoriasis
In September 2013, a 69-year-old Caucasian man who was anti–JC virus (JCV) antibody positive was admitted to our hospital with slowly progressing right hemiparesis and aphasia lasting for approximately 6 months. Medical history revealed arterial hypertension, biological aortic valve replacement, and psoriasis vulgaris, treated with 3–6 tablets daily of dimethylfumarate (DMF; 120 mg)/ethylhydrogenfumarate (EHF; 95 mg) (Fumaderm, Biogen Idec, Ismaning, Germany) since December 2008 (table e-1 at Neurology.org/nn). No other immunosuppressive pretreatment had been given. In April/May 2013, the patient recognized a s...

A Randomized Control Trial of Granulocyte Colony Stimulating Factor (G-CSF) Intervention in Acute Ischemic Stroke to Improve Functional Outcome (P1.139)
Conclusions: Endogenous mobilization of bonemarrow hematopoietic stem cells by GCSF administration perhaps leads to better functional outcome. This study provides preliminary evidence of potential safety, feasibility, and tolerability of G-CSF therapy in patients with acute ischaemic stroke. The safety and modest efficacy demonstrated in this study augurs for further studies with a larger sample sizes and longer follow ups.Disclosure: Dr. Gorthi has nothing to disclose.

Recurrent Intra-Luminal Aortic Thrombus And Ischemic Stroke In A Patient With Essential Thrombocythemia (P6.262)
CONCLUSIONS: This case highlights the importance of recognizing essential thrombocythemia as an entity that can lead to devastating complications, including acute coronary syndrome and either arterial and venous thrombosis. Early recognition and effective cytoreductive therapy are cornerstones to the prevention of recurrent embolism. This case demonstrates that Intra-luminal thrombus may resolve and reappear, and can vary greatly in its clinical consequences.Disclosure: Dr. Vela-Duarte has nothing to disclose.
