摘要:

Recent reports of declining trends in mortality rates from cerebrovascular disease are based on underlying cause of death as stated on the death certificate, and may contain inaccuracies because death certificates are often completed without reference to all information in medical records, and because of changes in coding conventions and diagnostic fashion. This is a report of trends in mortality rates from cerebrovascular disease in Baltimore, Md., during 1950–1970 using data validated by reference to individual medical records from 19 hospitals. Overall accuracy of death certificate diagnoses did not change markedly during the study period. Death rates from subarachnoid hemorrhage increased in white women, but decreased in white men and in nonwhites of both sexes. Death rates from other cerebrovascular diseases declined in most sex and color groups, a result which cannot be attributed to errors in death certificate diagnoses. The increasing rates of subarachnoid hemorrhage observed in white women deserve further attentio

摘要:

Potential risk factors for various types of stroke were studied using a case-control study design. All 1978 US death certificates for which the registered underlying cause of death was subarachnoid hemorrhage (SAH), cerebral hemorrhage (CH), or cerebral infarction (CI) were identified. The frequency with which other conditions appeared on the death certificates of cases with and without hypertension was compared with controls. These data provide new information, such as the occurrence of peripheral vascular disease in association with SAH, the risk of CH in epileptic and cirrhotic patients, and the association of benign neoplasms of the nervous system, motor neuron disease, and ''paralysis agitans'' with CI.

摘要:

An epidemiological study was performed with respect to Creutzfeldt-Jakob disease in a designated area in Japan. The subjects were observed in a small rural prefecture where the population generally remains within a limited radius throughout their lives. The patients'' life-styles in each area were investigated in detail. Nine cases appeared in 11 years; 6 were definitive and 3 probable. They were all of the subacute type; there were no noteworthy sexual differences, age of onset, course and/or past histories. Three of the nine cases came from two families; the relationship between familial and isolated cases was examined. Revealed facts and time-space clustering were investigated statistically, but no indication of natural transmission was observable.

摘要:

The pattern of industries, in terms of workers in any individual industry in relation to total population, was compared with multiple sclerosis (MS) risk, as reported in previous communications in Norway, Denmark, Sweden and Switzerland. A great number of correlations with MS was found but, when intercorrelations were considered, paper manufacturing appeared to be the most closely associated with MS. The possible relevance of these findings in view of the methodological limitations is discussed.

摘要:

A pilot study to demonstrate the feasibility of measuring prevalence and prevalence ratios of major neurological disorders was successfully carried out in an urban area of Madrid, Spain, in a population of 961 subjects. The most frequent disorders identified were migraine, epilepsy and peripheral neuropathy.

摘要:

A descriptive epidemiologic study of head injury cases that were discharged from army medical facilities during fiscal year 1983 was performed. For the diagnosis of concussion, the male and female rates were approximately equal between the ages 18–24 and 25–34 and for the total, ages 18–34. For the diagnosis of other- intracranial injury and the total of all head injuries, males between ages 18–24 and 18–34 had statistically significantly higher rates than females. Cases were reviewed from Walter Reed Army Medical Center to test the hypothesis that alcohol and drug abuse were underreported risk factors for military personnel sustaining head
