INTRODUCTION: Major surgery in the past 14 days is a relative contraindication to treatment of acute stroke with intravenous (IV) alteplase. The 2016 American Heart Association/American Stroke Association scientific statement discussing inclusion and exclusion criteria for alteplase in acute stroke allows for provider judgment citing a lack of evidence to support surgery as an absolute contraindication. CASE REPORT: A 59-year-old woman presented with acute left hemiparesis, dysarthria, and acute respiratory failure...

Ischemic stroke is a devastating neurological disorder and one of the leading causes of death and serious disability in adults. Adult neural stem cell (NSC) replacement therapy is a promising treatment for both structural and functional neurological recovery. However, for the treatment to work, adult NSCs must be protected against hypoxic-ischemic damage in the ischemic penumbra. In the present study, we aimed to investigate the neuroprotective effects of the mfat-1 transgene on cobalt chloride (CoCl2 )-induced hypoxic-ischemic injury in cultured adult NSCs as well as its underlying mechanisms...

Superior vena cava (SVC) syndrome, characterized by swelling of the upper torso, can result from a wide range of causes. The presence and severity of clinical symptoms depends on the degree of stenosis, the location of stenosis, the speed of development of stenosis, and existing collateral flow. Acute complete occlusion of the SVC frequently leads to poor neurologic outcomes such as coma or death. We report a case of a patient who had complete neurologic recovery after 26 minutes of acute total occlusion of the SVC...

BACKGROUND: Intracranial hypotension (IH) is a recognised cause of coma, however, the diagnosis is often challenging, especially in patients with superimposed traumatic brain injury (TBI). CASE REPORT: We report a case of a 67-year-old patient who became comatose following evacuation of bilateral acute subdural haematomas with concurrent respiratory failure. Imaging and intraparenchymal intracranial pressure (ICP) monitoring confirmed secondary IH. She was managed with an epidural blood patch, and a 72 hours period in the trendelenberg position guided by ICP monitoring and clinical assessment...

The authors demonstrate the use of an endovascular plug in securing a carotid artery pseudoaneurysm in an emergent setting requiring craniotomy for a concurrent subdural empyema. They describe the case of a 14-year-old boy with sinusitis and bifrontal subdural empyema who underwent transsphenoidal exploration at an outside hospital. An injury to the right cavernous segment of the ICA caused torrential epistaxis. Bleeding was successfully controlled by inflating a Foley balloon catheter within the sphenoid sinus, and the patient was transferred to the authors' institution...

Cardiogenic shock from acute severe mitral valve regurgitation can cause acute liver failure due to hypoperfusion. Impaired liver glycogenesis can then lead to profound hypoglycemia. The time frame for restoring normoglycemia without neurologic sequelae is not clearly established in humans. Thus, the clinical decision to provide further resuscitation in the setting of extreme hypoglycemia mainly depends on the patient's overall clinical condition, provider opinion, and/or institutional practice. Here, we report a case where the patient made complete neurologic recovery from extreme hypoglycemia (<5 mg/dL by central laboratory testing) secondary to acute cardiogenic shock and liver failure...

We investigated the effects of neuron-restrictive silencer factor (NRSF) on proliferation of endogenous nerve stem cells (NSCs) and on μ- and δ-opioid receptor (MOR/DOR) expression in rats after cerebral ischemia. Among 100 rats subjected to cerebral ischemia, 20 rats were transfected with NRSF shRNA, and the remaining 80 were randomly assigned to normal, sham, model, and negative control (NC) groups. On days 7, 14, and 28 after ischemia and reperfusion, neurological function scores were assigned and a step-down passive avoidance test was conducted...

OBJECTIVES: It is unclear whether scene time interval (STI) is associated with better neurological recovery in the emergency medical service (EMS) system with intermediate service level. METHODS: Adult out-of-hospital cardiac arrest (OHCA) patients with presumed cardiac etiology (2012 to 2014) were analyzed, excluding patients not-resuscitated, occurred in ambulance/medical/nursing facility, unknown STI or extremely longer STI (>60 min), and unknown outcomes...

BACKGROUND AND PURPOSE: Targeting the prostaglandin I2 prostanoid (IP) receptor to reduce stroke injury has been hindered by the lack of selective drugs. MRE-269 is the active metabolite of selexipag showing a high selectivity toward the IP receptor. Selexipag has been recently approved for clinical use in pulmonary hypertension. We hypothesized that postischemic treatment with MRE-269 provides long-lasting neuroprotection with improved neurological outcomes in a clinically relevant rat stroke model...

AIM OF THE STUDY: Combining xenon and mild therapeutic hypothermia (MTH) after cardiac arrest (CA) confers a degree of protection that is greater than either of the two interventions alone. However, xenon is very costly which might preclude a widespread use. We investigated whether the inexpensive gas argon would enhance hypothermia induced neurologic recovery in a similar manner. METHODS: Following nine minutes of CA and three minutes of cardiopulmonary resuscitation 21 male Sprague-Dawley rats were randomized to receive MTH (33°C for 6h), MTH plus argon (70% for 1h), or no treatment...

The prognosis in cervical spinal cord injury (SCI) is poor and surgical and neuro intensive care management need further improvement. Monitoring of the intraspinal pressure (ISP) at early stage after tSCI is clinically useful. Obtaining continuous spinal cord perfusion pressure (SCPP) measurements based on the difference between mean arterial pressure (MAP) and ISP allows offering best medical and surgical treatment during this critical phase of tSCI. The optimal SCPP was found to be between 90-100mmHg and MAP of 110-130...

Traumatic brain injury (TBI) can lead to long-term motor and cognitive dysfunction, which can be at least partly attributed to blood-brain barrier (BBB) disruption. The mechanisms underlying post-TBI BBB disruption, however, are poorly understood thus far. Na(+)-K(+)-2Cl(-) cotransporter isoform 1 (NKCC1) is a universally expressed ion transporter that maintains intracellular ion homeostasis by increasing intracellular K(+) and Cl(-). Having been characterized in stroke models, NKCC1 is activated in various cell types in the ischemic brain, and is thought to mediate BBB disruption, brain edema, and neuronal cell death...

BACKGROUND: Intracerebral hemorrhage (ICH) is an acute neurological disorder with high mortality and no effective treatment. In addition to the initial bleeding event, rebleeding and hematoma expansion are associated with poor outcome in these patients. We studied the effectiveness of the new antifibrinolytic agent CM352, a short-half-life matrix metalloproteinase inhibitor, for achieving early hemostasis and improving functional recovery in a rat model of collagenase-induced ICH. METHODS AND RESULTS: ICH was induced by striatal injection of collagenase, and 1 hour later, rats received an intravenous injection of saline (n=6) or CM352 (1 mg/kg, n=6)...

Degenerative cervical myelopathy (DCM) is the most common progressive nontraumatic spinal cord injury. The most common recommended treatment is surgical decompression, although the optimal timing of intervention is an area of ongoing debate. The primary objective of this study was to assess whether a delay in decompression could influence the extent of ischemia-reperfusion injury and alter the trajectory of outcome in DCM. Using a DCM mouse model, we show that decompression acutely led to a 1.5- to 2-fold increase in levels of inflammatory cytokines within the spinal cord...

INTRODUCTION: The study investigated the effect of untreated cardiac arrest (CA), i.e. "no-flow" time, on post-resuscitation myocardial and neurological injury, and survival in a pig model to identify an optimal duration that adequately reflects the most frequent clinical scenario. METHODS: An established model of myocardial infarction followed by CA and cardiopulmonary resuscitation was used. Twenty-two pigs were subjected to 3 no-flow durations: short (8-10 min); intermediate (12-13 min); and long (14-15 min)...

INTRODUCTION: Patients surviving a self-attempted hanging have a total neurological recovery in 57-77% of cases at hospital discharge, but no long-term data are available. METHODS: In this observational study, all patients hospitalized post-self-attempted hanging in the intensive care unit (ICU) in a 5-year period were included. Neurological evaluations at 6 and 12months were performed according to Cerebral Performance Category (CPC) scores. Factors associated with neurological recovery were determined by comparing CPC2+3+4 (bad recovery) vs...
