Thrombolysis for atlantoaxial dislocation mimicking acute ischemic stroke

The frequency of stroke mimics among stroke patients has been reported to be up to 30%, and that in patients who receive thrombolytic therapy ranges between 1% and 16%. Atlantoaxial dislocation with myelopathy mimicking stroke is extremely rare. An 83-year-old man with a history of old cerebellar infarction presented to the emergency department with acute left hemiplegia after a chiropractic manipulation of the neck and back several hours before symptom onset. Mild hypoesthesia was observed on his left limbs.

Patients who present emergently with focal neurological deficits concerning for acute ischemic stroke can be extremely challenging to diagnose and treat. Unnecessary administration of thrombolytics to potential stroke patients whose symptoms are not caused by an acute ischemic stroke —stroke mimics—may result in patient harm, although the overall risk of hemorrhagic complications among stroke mimics is low.

CONCLUSIONS: RSG treatment protects against BBB damage and ameliorates HT in delayed tPA-treated stroke mice by activating PPAR-γ and favoring microglial polarization toward anti-inflammatory phenotype. PMID: 31756041 [PubMed - as supplied by publisher]

AbstractPatients with atrial fibrillation (AF) who suffer an acute ischemic stroke are at risk for both hemorrhagic transformation and recurrent ischemic stroke in the acute post ‐stroke period. Oral anticoagulants are recommended for secondary stroke prevention in patients with AF. The optimal time to initiate anticoagulant therapy after acute ischemic stroke in patients with AF is uncertain. There is concern that early initiation increases the risk of hemorrhagic transfo rmation, whereas delayed initiation leaves the patient at risk for recurrent ischemic stroke. In this article, we provide a review of the risk of hemo...

A nationally recommended practice to accelerate thrombolytic therapy for acute ischemic stroke is to route emergency medical services (EMS)-transported stroke patients directly to the computed tomography (CT) scanner on arrival. We evaluated door-to-needle time with direct-to-CT routing versus emergency department (ED)-bed first routing.

Authors: Zhong W, Huang Q, Zeng L, Hu Z, Tang X Abstract Ischemic stroke is a leading cause of morbidity and mortality worldwide. Thrombolytic therapy, the only established treatment to reduce the neurological deficits caused by ischemic stroke, is limited by time window and potential complications. Therefore, it is necessary to develop new therapeutic strategies to improve neuronal growth and neurological function following ischemic stroke. Membrane lipid rafts (MLRs) are crucial structures for neuron survival and growth signaling pathways. Caveolin-1 (Cav-1), the main scaffold protein present in MLRs, targets man...

In this study, we synthesized a membrane-permeable peptide (Tat-CDK5-CTM) that specifically disrupts the binding of CDK5 and NR2B and then leads to the degradation of CDK5 by a lysosome-mediated pathway. We found that the administration of Tat-CDK5-CTM not only retards calcium overload and neuronal death in oxygen and glucose deprivation (OGD)-treated neurons but also reduced the infarction area and neuronal loss and improved the neurological functions in MCAO (middle cerebral artery occlusion) mice. The peptide-directed lysosomal degradation of CDK5 is a promising therapeutic intervention for stroke. Link:...

We report a single-center, retrospective assessment of the safety and efficacy of alteplase treatment within 45 minutes. Methods: Five hundred and eighty-six patients were treated with alteplase in our emergency departments (EDs) between January 2014 and October 2016; 368 patients were included for analysis.

This study showed that elevated level of neutrophil –lymphocyte ratio (NLR) may predict post‐thrombolysis early neurological deterioration (END) in ischemic stroke patients. A cutoff value of 4.43 for NLR was detected in predicting post‐thrombolysis END with a sensitivity of 70.9% and a specificity of 79.3% (area under curve, 0.779; 95% CI, 0.7 31–0.822). Furthermore, our established nomogram indicated that higher NLR was an indicator of post‐thrombolysis END (c‐index was 0.789,p

This study aimed to evaluate the feasibility and safety of thrombolytic therapy administration at Mittaphab Hospital, Lao PDR under the international telestroke consultation system from King Chulalongkorn Memorial Hospital, Thailand. Methods: Acute ischemic stroke patients who presented at Mittaphab Hospital within 4.5 hours after the onset and received thrombolytic therapy between December 2016 and June 2017 were studied.
