Older Age, Hypertension and Diabetes Influence the Proportion of Salvageable Ischemic Tissue Following Ischemic Stroke (P02.048)
CONCLUSIONS: Older patients and those with HTN or DM are less likely to have a large proportion of salvageable penumbra. While endothelial dysfunction may be a common denominator to these risk factors, the biological mechanisms underlying this phenomenon need to be elucidated.Disclosure: Dr. Mohamed has nothing to disclose. Dr. Jowkar has nothing to disclose. Dr. Bhattacharya has nothing to disclose.

Successful treatment with intravenous recombinant tissue plasminogen activator in an acute stroke patient presenting with hemiballism.
Authors: Bembenek JP, Bilik M, Członkowska A Abstract A 79-year-old woman with hypertension was evaluated 3 hours and 20 minutes after the sudden onset of left-sided weakness which lasted about 15 minutes and was followed by involuntary, coarse, flinging movements of the left extremities (hemiballistic), occurring every few minutes, and facial asymmetry. Brain computed tomography revealed no abnormalities. The patient received intravenous thrombolysis with 0.9 mg/kg of alteplase 4 hours after the symptom onset. Involuntary movements and central facial nerve paresis subsided within 48 hours of the thrombolysis. Mag...

Transoesophageal echocardiography prior to catheter ablation could be avoided in atrial fibrillation patients with a low risk of stroke and without filling defects in the late-phase MDCT scan: A retrospective analysis of 783 patients
ConclusionsFor AF patients with low risk of stroke, when MDCT images showed no filling defect in the late phase, TEE prior to catheter ablation can be avoided.Key Points•MDCT can help detect the presence of LAA thrombus.•TEE can be avoided when late-phase MDCT shows no filling defect.•TEE is required in patients whose MDCT images indicate thrombus.

Preoperative CT scan for postoperative stroke prediction in minimally invasive mitral valve surgery: Statistical concern for clinical factors in regression analyses
We read with great interest the paper by Leonard et al. [1] online published in IJC in Dec 12, 2018. They included 57 articles (19 CT versus 38 non-CT) with a total of 13,731 patients in the pooled analysis, and tried to identify the potential influential clinical factors of stroke occurrence following minimally invasive mitral valve surgery (MIMVS). Finally, 10 clinical factors (age, female gender, CAD, hypertension, non-CT screening, etc.) have been found to be with significant importance for the incidence of stroke using univariate mete-regression analyses.

Benedictine hand of 'central' origin
A 67-year-old man was admitted to emergency room to investigate a left hand weakness started on awakening. Anamnesis revealed only a mild hypertension currently treated with ACE-inhibitors. Antigravitary tests in upper limbs showed a ‘benedictine’ hand (figure 1A,B). Sensory examination was unremarkable although the patient complained of nocturnal paraesthesias in left hand. Brain CT scan was negative. Initial diagnosis was ischaemic stroke even if a proximal median nerve injury was mimicked. Nerve conduction study and electromyographic examination of left arm, performed the day after, showed only a ‘mild...

Difference in Aneurysm Characteristics Between Ruptured and Unruptured Aneurysms in Patients With Multiple Intracranial Aneurysms Clinical Sciences
Conclusions— Aspect ratio ≥1.3 and irregular shape are associated with aneurysm rupture independent of aneurysm size and location, and independent of patient characteristics. Additional studies need to assess to what extent these factors increase the risks of rupture of small aneurysms in absolute terms.

Otitis Media Leads to Brain Abscess Presenting as Stroke
By Mikhail Elfond, DO; Esi Quayson, MD; & Joseph V.M. Kelly, MD, MBA   A 65-year-old man presented to the ED via EMS with symptoms of stroke. The paramedics stated his right-sided weakness and speech difficulty started 40 minutes prior to presentation in the ED. En route to the hospital, paramedics observed four episodes of facial twitching.     Vitals signs were significant for a rectal temperature of 100.2°F and a fingerstick blood sugar of 220 mg/dL. History of present illness was significant for a diagnosis of left otitis media treated with Augmentin and Vicodin at an urgent care center one day prior to prese...

Radial palsy in the emergency department
Clinical introduction A 73-year-old patient with a medical history of hypertension and hypercholesterolaemia presents to the emergency department with sudden onset of weakness in the right hand and numbness in the right forearm and hand that began 5 h prior to his arrival. There was no history of trauma, he did not drink or smoke and review of systems was otherwise negative. On physical examination, there was right wrist drop with weakness of right wrist and finger extension (figure 1). Finger and wrist flexion were normal, reflexes were intact and there were no sensory alterations. The rest of the physical examinatio...

Letter to the Editor: Pneumocephalus: Is the needle size significant?
Discussion. Pneumocephalus is defined by two mechanisms: a ball-valve and an inverted bottle concept.1 The ball-valve type implies positive pressure events, such as coughing or valsalva maneuvers, that prevent air escape. Tension pneumocephalus is included in this mechanism, causing a parenchymal mass effect. The inverted bottle theory includes a negative intracranial pressure gradient following cerebrospinal fluid drainage, relieved by air influx. A small pneumocephalus is usually sealed by blood clots or granulation, allowing spontaneous reabsorption and resolution.[1] Otherwise, the lateral positioning of a patient duri...

Haemorrhagic stroke related to the use of 4-fluoroamphetamine
We report on two patients who presented with headache and mild hypertension after 4-FA use. Patient A developed one-sided weakness and decreased consciousness after a few hours. A computed tomography scan showed a left-sided intracerebral haemorrhage. Because of life-threatening cerebral herniation, haematoma evacuation was performed. Postoperatively, she suffered from a right-sided hemiparalysis and severe aphasia, requiring clinical rehabilitation. Patient B had a subarachnoid haemorrhage without neurological deficits. In total, 939 4-FA-intoxicated patients were registered. These patients used 4-FA alone (44%) or in com...
