Free CME Article: Coagulopathy After Traumatic Brain Injury
Traumatic brain injury has long been associated with abnormal coagulation parameters, but the exact mechanisms underlying this phenomenon are poorly understood. Coagulopathy after traumatic brain injury includes hypercoagulable and hypocoagulable states that can lead to secondary injury by either the induction of microthrombosis or the progression of hemorrhagic brain lesions. Multiple hypotheses have been proposed to explain this phenomenon, including the release of tissue factor, disseminated intravascular coagulation, hyperfibrinolysis, hypoperfusion with protein C activation, and platelet dysfunction. The diagnosis and management of these complex patients are difficult given the lack of understanding of the underlying mechanisms. The goal of this review is to summarize the current knowledge regarding the mechanisms of coagulopathy after blunt traumatic brain injury. The current and emerging diagnostic tools, radiological findings, treatment options, and prognosis are discussed.
Free Article: Is Trauma Transfer Influenced by Factors Other Than Medical Need? An Examination of Insurance Status and Transfer in Patients With Mild Head Injury
BACKGROUND: The Emergency Medical Treatment and Active Labor Act was meant to provide access to emergency medical care irrespective of financial resources. Yet, many Level I trauma Centers have raised concerns about the financial drivers influencing transfer.
OBJECTIVE: To study the relationship between insurance status and transfer, we focused on patients with mild head injury to tease apart the medical necessity for transfer from other potential drivers, such as financial factors.
METHODS: Using the 2002 to 2006 American College of Surgeons National Trauma Databank and Massachusetts General Hospital’s Trauma Databank from 1993 to 2009, we conducted a retrospective study and limited our population to patients with mild head injuries and mild to moderate systemic injuries as determined by the Glasgow Coma Scale, Abbreviated Injury Scale, or Injury Severity Score. Statistical analyses were conducted with STATA software.
Ahead of Print: The Royal Book by Haly Abbas From the 10th Century: One of the Earliest Illustrations of the Surgical Approach to Skull Fractures
Full article access for Neurosurgery subscribers.
Haly Abbas was one of the pioneering physicians and surgeons of the Eastern world in the 10th century who influenced the Western world by his monumental work, The Royal Book. The book was first partly translated into Latin by Constantinus Africanus in the 11th century without citing the author’s name. Haly Abbas was recognized in Europe after full translation of The Royal Book by Stephen of Antioch in 1127. The Royal Book has been accepted as an early source of jerrah-names (surgical books) in the Eastern world. The chapters regarding cranial fractures in Haly Abbas’ work include unique management strategies for his period with essential quotations from Paul of Aegina’s work Epitome. Both authors preferred free bone flap craniotomy in cranial fractures. Although Paul of Aegina, a Byzantine physician and surgeon, was a connection between ancient traditions and Islamic interpretation, Haly Abbas seemed to play a bridging role between the Roman-Byzantine and the School of Salerno in Europe.
