A population-based study of geriatric trauma in a rural state.

BACKGROUND: Urban geriatric trauma patients are known to die more often than their younger counterparts. Little is known of the fate of geriatric trauma patients in a rural environment where delays to definitive treatment are frequent. We hypothesized that rural trauma patients would do worse than their urban counterparts because of prolonged delays to definitive care. METHODS: Five-year retrospective analysis of all trauma deaths occurring within a rural state and retrospective outcome analysis of trauma patients admitted to a tertiary care facility who were less than 55 years old (defined as young) and 55 or more years old (defined as old). Outcome analysis was performed comparing old and young rural hospitalized patients to the Major Trauma Outcome Study data set collected in major urban trauma centers. RESULTS: Of the total trauma deaths in the state, 32.5% were old. Old patients were less likely to die at the scene of the injury than were their younger counterparts (R2 = 0.84, p < 0.001). Hospitalized old patients had a significantly higher mean Revised Trauma Score and a significantly lower Injury Severity Score, a higher complication rate, and a higher mortality rate than did hospitalized young patients. The young group had a significantly better survival (W = 0.59, Z = -3.49, p = 0.0001) than the MTOS data set, but the old group had a significantly worse survival (W = -1.8, Z = -3.49, p = 0.001). CONCLUSION: In a rural environment, old trauma patients die more commonly in the hospital than their younger counterparts, who die more commonly at the scene. Old trauma patients who die in the hospital were less severely injured than their younger counterparts who died in the hospital. Old patients admitted to this rural trauma center have a significantly worse survival than their urban counterparts despite the fact that young rural trauma patients do significantly better than their urban counterparts. Understanding the demographics of rural geriatric trauma may be useful in allocating resources in rural trauma system design. It must be understood that despite relatively low injury severity and physiologic stability, there is a significant potential for rural geriatric trauma patients to do poorly.

Fatal hemorrhage caused by varicose veins.

Varicose veins are a common, worldwide medical problem, but are generally considered non-life-threatening. We report three cases of fatal hemorrhage resulting from varicose veins and review the literature. The pathology of acute perforations onto the skin surface in varicose venous disease is described.

Cerebral vasculitis associated with cocaine abuse.

A variety of central nervous system pathology has been associated with cocaine abuse, including cerebral vasculitis. We report a case of a 25-year-old woman who died of hypoxic encephalopathy following cardiac arrest due to cocaine abuse. Autopsy revealed a distinctive cerebral vasculitis with features characteristic of hypersensitivity drug included vasculitis. The significance of cerebral vasculitis associated with cocaine is reviewed.

Hypersensitivity myocarditis and hepatitis associated with imipramine and its metabolite, desipramine.

We present two cases of myocarditis and hepatitis with histologic characteristics of hypersensitivity-mediated drug reactions associated with imipramine and its metabolite, desipramine. In one case, death was directly attributed to myocarditis; in the second case, the patient died of an acute myocardial infarct, but myocarditis may have played a contributory role. One patient was taking imipramine, and therapeutic concentrations of imipramine and desipramine were documented in postmortem blood. The other patient was receiving desipramine documented by in-patient hospital medication records. Both cases had liver lesions associated in the medical literature with adverse drug reaction to imipramine. Although myocarditis has been previously associated with amitriptyline, these cases appear to be the first reported in association with imipramine/desipramine. The fact that one patient was taking only desipramine suggests that it may be the offending agent.

Downhill ski fatalities: the Vermont experience.

All ski-related accidental deaths in Vermont during the 1979-1980 through 1985-1986 ski seasons are reported. Sixteen deaths occurred in downhill skiers at major ski areas. During the same period 24.17 million skier-days were logged for an estimated rate of one death per 1.5 million skier-days. Of the skiers 81% were male, and 62% were between the ages of 15 and 26 years. Fourteen of 16 cases resulted from collisions with objects, most commonly trees. The predominance of head and upper body injuries was striking, and fractures of the lower extremities were uncommon. Lethal head/neck injuries accounted for all but two of the deaths. Only one skier was wearing a helmet. Speed and loss of control were the two major contributing factors identified in these accidents. The need for research and development in the prevention of this class of ski accidents is emphasized.

Caffeine toxicity: a case of child abuse by drug ingestion.

The case of a 14-month-old child who died of caffeine toxicity is presented. The evidence for prolonged toxicity associated with inappropriate delay in the seeking of medical care and the presence of various recent and healing injuries are diagnostic of child abuse. Fatal caffeine toxicity and child abuse by drug/substance administration are uncommonly reported. Relevant medical literature is reviewed.

Death associated with inadvertent hydrocodone overdose in a child with a respiratory tract infection.

A 3-year-old child died of the combined effects of a bacterial superinfection and a relative overdose of hydrocodone prescribed for a cough due to a presumed viral respiratory tract infection. This case illustrates the importance of evaluating the effects of prescribed medication in assessing the cause and mechanism of death in children dying suddenly of presumed natural disease.

Accidental firearm fatalities in North Carolina, 1976-80.

All accidental gunshot fatalities in North Carolina were reviewed for the years 1976-80. There were 210 cases, of which 94 were self-inflicted and 116 were inflicted by others. Young white males predominated as victims, 31 per cent under the age of 15. Sixty-five per cent of the accidents occurred in the home and 18 per cent occurred in rural, "hunting" locations. Forty-one per cent of the cases involved shotguns, 39 per cent involved handguns, and 16 per cent, rifles. Sixteen per cent of the accidents involved children playing with guns and 14 per cent involved dropped or mishandled weapons. During the same period, there were 2,553 suicides and 2,509 homicides by firearm. Gunshot fatalities are an important American public health problem.

Testosterone effect on experimental diabetes mellitus in encephalomyocarditis (EMC) virus infected mice.

A diabetes mellitus-like disease occurs in male DBA/2 mice infected with the M variant of the encephalomyocarditis virus. Female mice of this strain sustain systemic infection, but rarely exhibit hyperglycaemia. The diabetogenic effects of the virus were studied in 3 groups of adult DBA/2 males-castrates, castrates treated with testosterone, and sham-operated controls. After infection, pancreatic insulin concentrations decreased precipitously to approximately 10% of control values in intact males and castrates treated with testosterone; hyperglycaemia occurred concomitantly in both groups. In contrast, untreated castrates failed to develop hyperglycaemia and the effect on the insulin content of the pancreas was less striking.
