Sonographic diameter of optic nerve sheath in differentiation of ischemic and hemorrhagic strokes; a diagnostic accuracy study
Differentiating between ischemic and hemorrhagic types is of special importance in the treatment process of patients with stroke. The present study was designed with the aim of evaluating the diagnostic accuracy of ultrasonographic optic nerve sheath diameter (ONSD) in differentiation of ischemic from hemorrhagic stroke.

Utilization of lysis percentage via thromboelastography for tissue plasminogen activator-induced symptomatic intracranial hemorrhage
Alteplase, the only FDA approved tissue plasminogen activator (tPA), remains one of the cornerstones of acute ischemic stroke (AIS) management. Just as with endogenous tPA, recombinant tPA promotes the activation of plasmin and the subsequent degradation of cross-linked fibrin to fibrin byproducts [1]. The most feared complication of recombinant tPA administration is the development of symptomatic intracranial hemorrhage (sICH), which occurs in approximately 5.6% of tPA administrations, utilizing the European Cooperative Acute Stroke Study definition, with roughly half of these cases resulting in death [2].

Subconjunctival hemorrhage in a patient on dabigatran (Pradaxa)
Dabigatran is a direct thrombin inhibitor that has gained increasing popularity for prevention of thromboembolic events such as stroke, pulmonary embolism, and myocardial ischemia. Because of the increasing use of this drug, emergency department (ED) physicians are going to be evaluating patients taking this medication. It is important to understand the potential for ocular bleeding complications associated with this class of anticoagulant. Traditionally, patients have been placed on vitamin K antagonists to decrease the risk of thromboembolism. In the RE-LY and RE-COVER studies, dabigatran showed non-inferiority to coumad...

Abnormal troponin level as short-term predictor of poor outcome in acute atrial fibrillation
Abstract: Background: The link between minor troponin (cardiac troponin I [cTnI]) elevations and atrial fibrillation (AF) is still debated.Methods: A total of 948 patients with AF lasting less than 48 hours participated in the study and were required to undergo 1-month and 12-month follow-up. The exclusion criteria were represented by younger than 18 years, the presence of hemodynamic instability, or severe comorbidity. Primary end point was the composite of ischemic vascular events inclusive of stroke, acute coronary syndrome, revascularization, and death.Results: In the short term, 4 patients (5%) of 78 with abnormal cTn...

Lung transplant of extrahospitalary donor after cardiac death
The objective of this study is to describe the results of lung transplantation of after cardiac death program, specifically the section regarding lung extraction donation. Twenty potential lung donors were obtained during the study. Most patients were male (19 cases), with a mean age of 42 years (36.5-49.5 years). A total of 33 lungs were donated (18 right and 15 left lungs). Most extractions were multiorganic (19 cases). One liver, 19 kidneys, 2 pancreas, and 19 corneas were obtained from these donors; bone tissue was obtained from all donors. The transplantation was bipulmonary in 13 cases and unipulmonary in 7. Thirty d...

Troponin rise and poor outcome in patients with acute atrial fibrillation: rationale and criteria of selection of patients
The role of new onset atrial fibrillation (AF) as a marker of thromboembolic risk has been demonstrated in the setting of acute myocardial infarction . Thus, someone might inquire the role of acute AF in patients with abnormal troponin not fulfilling criteria of acute myocardial infarction and might question if the minor reported range of troponin I (cTn-I) values in the study population of Conti et al (from 0.15 to 7.0 ng/mL) may not be linked with a secondary ischemic mechanism, likely an imbalance between demand and supply . However, the independent predictive value of abnormal troponin for a composite of stroke, acute ...

S100B protein in children with carbon monoxide poisoning
S100B has been shown to increase in patients with cardiac arrest, stroke, subarachnoid hemorrhage, and traumatic and hypoxic brain damage . In contrast to adult studies, we found that serum S100B protein levels did not increase in pediatric patients with carbon monoxide (CO) poisoning . Patients with a positive history of CO exposure and elevated blood carboxyhemoglobin (>10%) levels associated with relevant clinical findings were diagnosed with CO poisoning. The most common complaints were headache (n = 27), dizziness (n = 27), nausea and vomiting (n = 28), syncope (n = 7), and convulsion (n = 2). In addition, we also cla...

Fatal heat stroke associated with topiramate therapy
A 40-year-old man with diabetes and seizure disorder was found at home unresponsive and “very hot to touch” by his father 40 minutes before emergency medical services arrival. His usual medications included topiramate, divalproex sodium, and rosiglitazone/metformin. Paramedics administered oxygen, intravenous fluids, and naloxone. They did not witness or report seizure activity. Upon emergency department arrival, the patient was unresponsive (Glasgow Coma Scale 3), hypotensive (94/50 mm Hg), and tachypneic (32 breaths per minute), with a heart rate of 60 beats per minute and elevated rectal temperature peaking at 43.2...

N-terminal prohormone of brain natriuretic peptide—how far can we extrapolate?
We read the article by Velibey et al with interest. Their result is consistent with various other studies done in the past, but long-term (4 years) survival prediction on hospital admission with a single plasma N-terminal prohormone of brain natriuretic peptide (NT-proBNP) level is a new and important finding. The mean value of NT-proBNP is significantly correlated with ejection fraction and the functional class (New York Heart Association Class) of heart failure . The author had neither commented on the functional status of the patients nor on the etiology of acute shortness of breath at the time of admission. Testing the...

A patient with altered mental status and possible seizure reveals an atypical aortic dissection upon workup
In this report, we present the case of a 57-year-old woman who was transported to the emergency department with an acute episode of altered mental status, presenting as a possible stroke with possible seizures. The patient's only complaint was mild low back pain. Physical examination revealed disorientation to time with no other neurologic deficits or abnormal findings. Results from initial noncontrast head computed tomography, chest radiograph, and laboratory studies were all normal, except for an elevated d-dimer and serum creatinine. Chest computed tomography with contrast demonstrated a type A aortic dissection. The pa...

Neurogenic pulmonary edema following severe head injury: A transpulmonary thermodilution study
We report a fatal case of a 55-year old man who was admitted because of severe head injury. The diagnosis of NPE was considered according to clinical and radiological findings. Transpulmonary thermodilution (TPT) study showed decreased stroke volume index (SVI) and cardiac function index (CFI). Indexed extravascular lung water (EVLWI) was increased as well as pulmonary vascular permeability index (PVPI).

Brugada Electrocardiogram Pattern Induced by Cannabis; is cannabis safe?
The objective of this study was to present a case report that bring attention to relationship between cannabis consumption and Brugada electrocardiogram pattern (BEP). Here we present a case of a 19-year-old male patient with symptomatic BEP induced after cannabis consumption. With the potential for more widespread legalization of cannabis several studies are raising the issue of adverse vascular effects of cannabis, including myocardial infarction, sudden cardiac death, cardiomyopathy, stroke, transient ischemic attack, and cannabis arteritis.
