REVIEW
Ha Nguyen, Ninh Doan, Michael Gelsomino, Saman Shabani
BACKGROUND: In the setting of trauma, the etiology of intracranial hemorrhage (ICH) is frequently attributed to the physical, traumatic event. Caution should still be directed towards non-traumatic (or spontaneous) etiologies responsible for the trauma, such as hypertension, cerebral amyloid angiopathy, aneurysms, vascular malformation, and hemorrhagic infarcts. The role for immediate CT angiography (CTA) remains controversial to evaluate for non-traumatic etiologies. METHODS: A systematic review of the available literature in Medline PubMed database...

OBJECTIVE: Diagnosis of reversible cerebral vasoconstriction syndrome (RCVS) is currently based on luminographic findings of vasoconstriction. In addition to vasoconstriction, the blood-brain barrier (BBB) breakdown has been postulated as a central mechanism of RCVS. Our aim was to document BBB breakdown in patients with RCVS and its role for the pathophysiology-based diagnosis of RCVS. METHODS: We prospectively recruited 72 consecutive patients with thunderclap headache who did not have aneurysmal subarachnoid hemorrhage from April 2015 to July 2016 at the Samsung Medical Center...

Neurocardiology refers to the interplay between the nervous system and the cardiovascular system. Stress-related cardiomyopathy exemplifies the brain-heart connection and occurs in several conditions with acute brain injury that share oversympathetic activation. The brain's influences on the heart can include elevated cardiac markers, arrhythmias, repolarization abnormalities on electrocardiogram, myocardial necrosis, and autonomic dysfunction. The neurogenic stunned myocardium in aneurysmal subarachnoid hemorrhage represents one end of the spectrum, and is associated with an explosive rise in intracranial pressure that results in excess catecholamine state and possibly CBN...

OBJECTIVES: Impaired oxygen delivery due to reduced cerebral blood flow is the hallmark of delayed cerebral ischemia following subarachnoid hemorrhage. Since anemia reduces arterial oxygen content, it further threatens oxygen delivery increasing the risk of cerebral infarction. Thus, subarachnoid hemorrhage may constitute an important exception to current restrictive transfusion practices, wherein raising hemoglobin could reduce the risk of ischemia in a critically hypoperfused organ...

PURPOSE OF REVIEW: Unruptured intracranial aneurysms and vascular malformations are detected more frequently because of the increased use and availability of brain imaging. Management of these entities requires knowledge of which patients are at high risk for hemorrhage and what treatment options are available. This article summarizes the epidemiology, natural history, and management strategies for unruptured intracranial aneurysms, arteriovenous malformations, cavernous malformations, developmental venous anomalies, and capillary telangiectasias...

OBJECTIVE: Secondary brain injury leads to high morbidity and mortality rates in patients with aneurysmal subarachnoid hemorrhage (aSAH). However, evidence-based treatment strategies are sparse. Since heparin has various effects on neuroinflammation, microthromboembolism and vasomotor function, our objective was to determine whether heparin can be used as a multitarget prophylactic agent to ameliorate morbidity in SAH. METHODS: Between June 1999 and December 2014, 718 patients received endovascular treatment after rupture of an intracranial aneurysm at our institution; 197 of them were treated with continuous unfractionated heparin in therapeutic dosages after the endovascular procedure...

The Middle East respiratory syndrome corona virus (MERS-CoV) is a novel positive sense singlestranded ribonucleic acid virus of the genus Beta corona virus. This virus was first isolated from a patient who died from severe respiratory illness in June 2012 in Jeddah, Kingdom of Saudi Arabia. We describe an unusual case of a 42 year old healthcare worker who was admitted to our Intensive Care Unit (ICU)King Abdul-Aziz Medical City, with MERS-CoV and severe acute respiratory distress Syndrome and developed a sudden-onset diabetes insipidus and spontaneous massive intracranial hemorrhage with intra-ventricular extension and tonsillar herniation...

Current treatments for brain aneurysms are invasive, traumatic, and not suitable in most patients with increased risks. A new alternative method is using scaffold stents to create a local and focal attraction force of cells for an in situ reconstruction of the tunica media. For this purpose, a nanostructured bioactive coating is designed to render an asymmetric region of the stent scaffold magnetic and biomimetic, which utilizes bacterial nanocellulose (BNC) as a platform for both magnetic and cell attraction as well as proliferation...

INTRODUCTION: Recently, there have been increasingly fewer opportunities for junior surgeons to receive on-the-job training. Therefore, we created custom-built three-dimensional (3D) surgical simulators for training in connection with cerebral aneurysm clipping. METHODS: Three patient-specific models were composed of a trimmed skull, retractable brain, and a hollow elastic aneurysm with its parent artery. The brain models were created using 3D printers via a casting technique...

Gunshot injuries are the most common cause of penetrating brain injury (PBI) and carry a high morbidity and mortality. The incidence of PBI has increased over the last decade with an estimated 35,000 civilian deaths annually. Patients that survive to reach the hospital require rapid triage and imaging evaluation. CT findings in conjunction with the Glasgow Coma Scale are typically used to determine which patients are surgical candidates. Radiologists should be familiar with the various injury patterns and imaging findings which are poor prognostic indicators, notably brainstem, bilateral hemispheric, multilobar, or transventricular injuries...

OBJECTIVE: While vein of Galen aneurysmal malformations (VGAM) can be diagnosed in the fetus, the challenge is predicting the occurrence of its two major complications: cardiopulmonary failure and encephalomalacia. This study attempts to determine which fetal brain MRI features might be used to predict the development of these complications at birth. METHODS: The cohort was extracted from a prospectively-assembled database of VGAM cases managed at a single referral centre from 2000 to 2014...

INTRODUCTION: Adipsic diabetes insipidus (ADI) is a very rare disorder, characterized by hypotonic polyuria due to arginine vasopressin (AVP) deficiency and failure to generate the sensation of thirst in response to hypernatraemia. As the sensation of thirst is the key homeostatic mechanism that prevents hypernatraemic dehydration in patients with untreated diabetes insipidus (DI), adipsia leads to failure to respond to aquaresis with appropriate fluid intake. This predisposes to the development of significant hypernatraemia, which is the typical biochemical manifestation of adipsic DI...

BACKGROUND: Despite recent advances in the medical and surgical fields, complications such as infection, pneumonia, or brain swelling may occur after a craniotomy. In some patients, perioperative antibiotic prophylaxis causes adverse effects such as itching, rash, or digestive conditions. Certain patients still develop infections severe enough to require a repeat operation despite antibiotic prophylaxis. Acupuncture has been used to treat inflammatory conditions, and many basic and clinical studies have provided evidence of its anti-inflammatory and immune regulatory effects...

An 85-year-old man complained of a 2-month history of pain on the left side of his face. Brain computed tomography (CT) and magnetic resonance imaging/magnetic resonance angiography did not clearly show any intracranial abnormality and only showed fluid effusion in his left sphenoid sinus. Filamentous fungi were detected from the left sphenoid sinus specimen. The isolate was Scedosporium apiospermum. He was empirically treated with voriconazole, to which the isolate was susceptible. His consciousness decreased rapidly...

OBJECTIVE: Retrograde neuronal cell death does not occur in mature motoneurons following the axonal injury of peripheral nerves. However, a previous study suggested that retrograde neuronal cell death does occur in adult rats after the creation of double lesions on the hypoglossal (XII) nerve based on a substantial decrease in the number of XII neurons. Using stereological methods, we examined neuronal apoptosis in XII neurons and the total number of XII neurons following repeated crush injuries to the XII nerve...
