The Epidemiology and Clinical Associations of Stroke in Patients with Acute Myeloid Leukemia: A review of 10,972 admissions from the 2012 National Inpatient Sample
Conclusions Patients with AML have an elevated risk of CVA compared to all inpatients and mortality in this population is high. Better characterization of risk factors of stroke in this vulnerable population is still needed. Teaser Acute leukemia predisposes patients toward the development of stroke. The latter, while devastating clinically, has been infrequently studied. Our study, using the 2012 National Inpatient Sample, found a 50-fold increase in the risk of stroke as compared to all inpatient admissions with a corresponding 5.5-fold increased risk of mortality. Significant risk factors for the development of stroke i...

Neuroprotective effects of polydatin against mitochondrial-dependent apoptosis in the rat cerebral cortex following ischemia/reperfusion injury.
Authors: Gao Y, Chen T, Lei X, Li Y, Dai X, Cao Y, Ding Q, Lei X, Li T, Lin X Abstract The neuroprotective effect of polydatin (PD) against hemorrhagic shock-induced mitochondrial injury has been described previously, and mitochondrial dysfunction and apoptosis were reportedly involved in ischemic stroke. In the present study the neuroprotective effect of PD in preventing apoptosis was evaluated following induction of focal cerebral ischemia by middle cerebral artery occlusion (MCAO) in rats. PD (30 mg/kg) was administered by caudal vein injection 10 min prior to ischemia/reperfusion (I/R) injury. 24 h following...

Rare-33. intracerebral hemorrhage as rare complication of intravascular lymphoma
Intravascular lymphoma (IVL) is an aggressive multifocal large cell lymphoma, characterized by neoplastic proliferation and vascular occlusion within the lumina of arterioles, capillaries and venules with a predilection for the central nervous system and skin. The clinical presentation is frequently non-specific and may consist of changes in mental status, focal neurological deficits, seizures, fevers of unknown origin and skin changes. Due to the rarity and absence of specific diagnostic procedures apart from biopsy, diagnosis is difficult and often post-mortem. Neuroimaging findings vary widely, ranging from normal to di...

Glioblastoma mimicking meningioma: report of 2 cases
Glioblastoma can mimic various pathologies, including arteriovenous malformation, hemorrhage from ischemic stroke, cerebral contusion, metastatic disease, lymphoma, and infection. The literature is limited regarding diagnostic confusion with meningioma. Herein, we present two patients that exhibited imaging, including cerebral angiography during preoperative embolization, which was consistent with meningioma, but where final surgical diagnosis revealed glioblastoma.

Non-traumatic Cerebral Fat Embolism in Sickle Cell Disease (P3.234)
Conclusions:Our case series illustrates the following clinical pearls: a) SCD-related CFES is vastly under-diagnosed, as it closely mimics sepsis, vasculitis or hypoxic ischemic encephalopathy; b) The diagnosis is confirmed with SWI that demonstrates pathognomonic microbleeds in the splenium and subcortical location; c) SCD-related CFES carries considerable morbidity and mortality.Disclosure: Dr. Ramachandiran has nothing to disclose.

Off-Hour Admission and Mortality Risk for 28 Specific Diseases: A Systematic Review and Meta-Analysis of 251 Cohorts Epidemiology
Conclusions Off-hour admission is associated with increased mortality risk, and the associations varied substantially for different diseases. Specialists, nurses, as well as hospital administrators and health policymakers can take these findings into consideration to improve the quality and continuity of medical services.

EP3, Prostaglandin E2 Receptor Subtype 3, Associated with Neuronal Apoptosis Following Intracerebral Hemorrhage.
Abstract EP3 is prostaglandin E2 receptor subtype 3 and mediates the activation of several signaling pathways, changing in cAMP levels, calcium mobilization, and activation of phospholipase C. Previous studies demonstrated a direct role for EP3 in various neurodegenerative disorders, such as stroke and Alzheimer disease. However, the distribution and function of EP3 in ICH diseases remain unknown. Here, we demonstrate that EP3 may be involved in neuronal apoptosis in the processes of intracerebral hemorrhage (ICH). From the results of Western blot and immunohistochemistry, we obtained a significant up-regulation o...

E-075 neurosarcoidosis presenting as aneurysmal subarachnoid hemorrhage: an interesting case and novel treatment
Neurosarcoidosis, the term used for sarcoidosis involving the central nervous system, represents an uncommon form of sarcoidosis, found in a 5% of patients with systemic sarcoidosis. Clinically evident cerebrovascular involvement in neurosarcoidosis has been reported but appears to be an extremely rare manifestation of neurosarcoidosis. The literature describes these cerebral vasculopathic changes as areas of stenosis and/or vascular irregularity, with clinical manifestations including headache, ischemic stroke, and parenchymal hemorrhage. Neurosarcoidosis has even been described as the etiology for a case of moyamoya synd...

Neuroprotective Role of an N-acetyl Serotonin Derivative via Activation of Tropomyosin-related Kinase Receptor B after Subarachnoid Hemorrhage in a Rat Model.
This study is to investigate a potential role of HIOC on ameliorating early brain injury after experimental subarachnoid hemorrhage (SAH). One hundred and fifty-six adult male Sprague-Dawley rats were used. SAH model was induced by endovascular perforation. TrkB small interfering RNA (siRNA) or scramble siRNA was injected intracerebroventricularly 24hours before SAH. HIOC was administrated intracerebroventricularly 3hours after SAH and compared with brain-derived neurotrophic factor (BDNF). SAH grade and neurologic scores were evaluated for the outcome study. For the mechanism study, the expression of TrkB, phosphorylated ...

Methotrexate Encephalopathy as a Cause of Alternating Hemiplegia (P3.143)
CONCLUSIONS: Transient neurologic dysfunction with reversible MRI abnormality is a recognized consequence of intrathecal methotrexate chemotherapy in childhood ALL. Patients present with dramatic fluctuating neurologic symptoms with associated MRI changes and may be mistaken for stroke or a seizure disorder. Once the syndrome is recognized patients typically recover with supportive management and rehabilitation.Disclosure: Dr. Sullivan has nothing to disclose. Dr. Quealy has nothing to disclose.

5 Scary Symptoms That Are Usually Harmless
SPECIAL FROM Next Avenue By Linda Melone After 50, aches, pains and the occasional muscle twinge become a fact of life. But some symptoms that may seem frightening or serious turn out to be far less than they appear. While you should always see a doctor if you experience something out of the ordinary, these signs generally are more smoke than fire: A Bloody Nose Nosebleeds can be particularly frightening due to the suddenness in which they occur and the sometimes large amount of blood involved. “People worry that it’s internal bleeding, but almost every time it’s not,” says Dr. Carlo Reyes, emergency room...

Genetic deletion of calcium/calmodulin-dependent protein kinase kinase ß (CaMKK ß) or CaMK IV exacerbates stroke outcomes in ovariectomized (OVXed) female mice
Conclusions: Inhibition of CaMKK signaling exacerbated stroke outcome and increased BBB impairment, transcriptional inactivation and inflammatory responses in females after stroke. Therefore, CaMKK signaling may be a potential target for stroke treatment in both males and females.

Summary: International Kidney Cancer Symposium
Conclusions:  Ideal ischemia time is 20-25 minutes or less improves short and long term renal function.  >25 minutes carried 5 year risk of new onset stage 4 CKD No differences on GFR for cold vs. warm ischemia times Preoperative GFR and the percent of kidney preserved was a better predictor of post op GFR.  No ischemia preserves renal function better than warm. Longer cold ischemia times were equivalent to shorter warm ischemia times. Quality and quantity of the remaining kidney is associated with ultimate renal function.
