Before Scott-Bell, Andrea Bethesda, MD 20894, Web Policies Zuckerman, Scott L However, a July 2007 eMedicine report summarizing an article in the American Journal of Sports Medicine noted: A study of American high school and college football players demonstrated 94 catastrophic head injuries (significant intracranial bleeding or edema) over a 13-year period.3 Of these, only two occurred at the college level. Management and prevention of sport-related concussion. and 90. Recently SIS has gained increased attention as many cite athletes sustaining a concussion and returning to the sport early as being particularly at risk. A thorough history is imperative and must be taken from the patient, if conversant, or from a witness. Buzzini SR, Guskiewicz KM. All reports of SIS were eligible regardless of patient age. Boca Raton (FL): CRC Press/Taylor & Francis; 2015. Kolb JJ.

Neurological death was determined by clinical criteria 4 days after the final injury, and her parents agreed to perfused organ donation. She sat up momentarily then lost consciousness. Toth C, McNeil S, Feasby T. Central nervous system injuries in sport and recreation: a systematic review. The progression of cerebral edema and loss of graywhite matter differentiation, despite surgical and medical intervention including craniectomy, can be seen. Young children have the highest rates of concussion, with sports and bicycle accidents accounting for the majority of cases in the 514 age group. The most sensible approach to prevention is to prevent the first concussion. There was generalized axonal damage indicative of diffuse axonal injury (DAI) of multifactorial etiology, including HIE, mass effect/herniations and acceleration/deceleration forces with scattered axonal swellings in the corpus callosum, dorsal brainstem, and cervical cord. Four manuscripts described these cases and discussed causes of death (20,40,69,95). Tator CH. General Medical Conditions: Special Communication, Categorization of articles defining second impact syndrome.. and Our review found that most articles define SIS as a syndrome requiring catastrophic brain injury after consecutive concussive episodes. Some term this malignant brain swelling.Reference Wetjen, Pichelmann and Atkinson3 It is uncertain how the antecedent concussion makes the brain so vulnerable to another hit. A patient should be seen in an emergency department right away if symptoms worsen and/or if the patient has: one pupil larger than the other, worsening headaches, seizures, neck pain, unusual behavior change, increased drowsiness, repeated vomiting, slurred speech, problems recognizing people or places, increased confusion, weakness or numbness in arms or legs, or if the patient cant be awakened or is less responsive than usual. 34. This makes the brain more vulnerable and susceptible to death after a second sub-lethal insult of even less intensity.11 Fisher and Vaca17 hence conclude that when the patient sustains a second impact, the brain loses its ability to auto regulate intracranial and cerebral perfusion pressures. The epidemiology and impact of traumatic brain injury: a brief overview. Xie, Lucy Biddiss, Elaine SIS causes rapid brain swelling resulting in coma or death. The literature searches identified 144 articles with an additional eight articles and one textbook identified through examination of references or citing articles (Fig.).

The detective assigned to the inquest retrieved Rowans cell phone and downloaded her texted messages. Falls and vehicular accidents are the most common causes of concussion in adults.5 There is little epidemiological data about SIS. When 2 impacts occur in very close succession (during the same game or within a few days), it is impossible to determine whether it was the initial injury that may have given rise to the catastrophic consequences. Ling GS, Marshall SA. Timmons, Shelly D Berger, Mitchel S and transmitted securely. Dimou S, Lagopoulos J. However, a patient who is suspected of suffering from SIS Boden BP, Tacchetti RL, Cantu RC, Knowles SB, Mueller FO. DAI can produce profound neurological damage but usually does not induce rapid, massive brain swelling.Reference Gentleman, Roberts and Gennarelli5, Reference Su, Bell, Laskowitz and Grant6 All authors agreed this rare and unusual case could be SIS, and that an inquest was needed to determine the diagnosis. Tator, Charles H While these articles contain the above statement, they all subsequently describe the sequela of more serious brain injury (generally, cerebral edema). The left hemispheric convexity protruded through the craniectomy site, and there was herniation of both temporal unci at the tentorial hiatus and both cerebellar tonsils at the foramen magnum.

Anterograde amnesia is the inability to retain new information. The impact of the second event does not have to be strong to trigger second impact syndrome. The cause of death determined at the inquest was SIS, and this conclusion was based on all the clinical, radiological, and neuropathological evidence.Reference McNaughton-Filion7 However, Rowans texted testimony of antecedent concussions was the most significant evidence. Furthermore, there are no similar reports from the European literature. Previous concussions may set the stage for the massive brain swelling that ensues. 23.

Of the 91 sources identified, 79 (87%) clearly specified that SIS involved either cerebral edema or death after a concussion when a prior concussion had not resolved. A minor blow to the head, chest or back that snaps the head enough to cause the brain to move inside the skull can trigger the usually lethal damage.

Tang, Alan R In post-concussive syndrome, up to three symptoms arise within less than four weeks from the initial LOC.5 These include headache, dizziness, fatigue, insomnia, irritability and alcohol intolerance, and other symptoms, such as subjective concentration, memory, or intellectual difficulties without neuropsychological evidence of marked impairment.5 In an article summarizing the Second International Conference on Concussion in Sport (Prague 2004), McCrory et al.12 differentiate between simple and complex concussions.

Bayley, Mark Because concussions are common, and second concussions while still symptomatic likely occur with some regularity, it is incomprehensible that a concussion atop of an unresolved primary concussion results in death 50% of the time. The primary purpose of this study was to systematically review the literature that includes a definition of sports-related SIS with the goal of more clearly defining the concept. In a series of publications in World Neurosurgery, 83. A concussion is a disturbance in brain function that occurs following either a blow to the head or as a result of the violent shaking of the head. If we define a direct fatality as one occurring directly from participation in the skills of a sport as opposed to an indirect fatality, which is one caused by systemic failure as a result of exertion while participating in a sport, head injury is the most frequent direct cause of death in sport.

The authors wish to acknowledge the generous contribution of this patients parents who provided consent for publication of this report. This is thought to be accomplished by acutely limiting cerebral blood flow, which leads to accumulation of lactate and intracellular acidosis.15 After the initial phase, a state of altered cerebral metabolism occurs and may last ten days,16 involving decreased protein synthesis and reduced oxidative capacity.11 Extensive experimental research suggests that the loss of consciousness after head injuries, the development of secondary brain damage, and the enhanced vulnerability of the brain after an initial insult can be explained largely by characteristic ionic fluxes, acute metabolic changes, and cerebral blood flow alterations that occur immediately after cerebral concussions.
