This case highlights potential long-term neurodegenerative outcomes in retired professional National Football League players subjected to repeated mild traumatic brain injury. The prevalence and pathoetiological mechanisms of these possible adverse long-term outcomes and their relation to duration of years of playing football have not been sufficiently studied. We recommend comprehensive clinical and forensic approaches to understand and further elucidate this emergent professional sport hazard.
Our first and second cases both had long careers without multiple recorded concussions. Both manifested Major Depressive Disorder after retirement. Amyloid plaques were present in the first case and completely absent in the second case. Both cases exhibited neurofibrillary tangles, neuropil threads, and coronary atherosclerotic disease. Apolipoprotein-E4 genotypes were different. Reasons for the contrasting features in these two cases are not clear. Further studies are needed to identify and define the neuropathological cascades of chronic traumatic encephalopathy in football players, which may form the basis for prophylaxis and therapeutics.
Treatment for individuals suffering from migraines and pain due to an inflammation or impingement of a nerve range from noninvasive methods such as massage, physical therapy, and medications to invasive methods such as epidural steroid injections and surgery. Each method of treatment has an associated level of risk. While minor to moderate complications from such procedures do occur, deaths are very rare. We report the first cited case of a death associated with the pain management procedure called nerve root block, also referred to as a transforaminal epidural steroid injection. We present the medical history and autopsy findings of a 44-year-old white female who died of massive cerebral edema secondary to the dissection of the left vertebral artery and subsequent thrombosis due to the perforation of that artery by a 25-gauge spinal needle during a C-7 nerve root block.
Background: Bariatric surgery has emerged as the most effective treatment for class III obesity (body mass index, Ն40). The number of operations continues to increase. We measured case fatality and death rates by time since operation, sex, age, specific causes of death, and mortality rates. Design and Setting: Data on all bariatric operations performed on Pennsylvania residents between January 1, 1995, and December 31, 2004, were obtained from the Pennsylvania Health Care Cost and Containment Council. Matching mortality data were obtained from the Division of Vital Records, Pennsylvania State Department of Health. Outcome Measures: Age-and sex-specific death rates after bariatric surgery. Results: There were 440 deaths after 16 683 operations (2.6%). Age-specific death rates were much higher in men than in women and increased with age. Age-and sexspecific death rates after bariatric surgery were substantially higher than comparable rates for the age-and sexmatched Pennsylvania population. The 1-year case fatality rate was approximately 1% and nearly 6% at 5 years. Less than 1% of deaths occurred within the first 30 days. Fatality increased substantially with age (especially among those Ͼ65 years), with little evidence of change over time. Coronary heart disease was the leading cause of death overall, being cited as the cause of death in 76 patients (19.2%). Therapeutic complications accounted for 38 of 150 natural deaths within the first 30 days, including pulmonary embolism in 31 (20.7%), coronary heart disease in 26 (17.3%), and sepsis in 17 (11.3%). Conclusions: There was a substantial excess of deaths owing to suicide and coronary heart disease. Careful monitoring of bariatric surgical procedures and more intense follow-up could likely reduce the long-term case fatality rate in this patient population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
