A series of three cases of isolated myocarditis, presenting as sudden death in infancy, occurred over a period of 3 months. This prompted a review of the autopsy records of the Children's Hospital of Winnipeg. Over a period of 40 years, 24 cases of isolated myocarditis were traced from 3196 autopsies. Most (21 of 24) cases of isolated myocarditis occurred in infants less than 12 months of age. In 16 of the infants there were either no antecedent clinical signs (sudden deaths), or a short clinical history of less than 24 h duration. Heart weights, however, were greater than the 99th percentile of published normals in three infants and above the 95th percentile in a further 16 infants. Areas of hypertrophied fibres were seen even in infants with a short history. These latter findings suggest that a latent phase of myocarditis may exist. The responsible pathogens were identified very rarely, due to a lack of suspicion of the existence of myocarditis, and it is suggested that samples of myocardium should be submitted for virologic examination in all cases of sudden death in the first year of life.  相似文献

Empirical studies that use reported crime data to evaluate policies for reducing crime will understate the true effectiveness of these policies if crime reporting/recording behavior is also affected by the policies. For instance, when the size of the police force increases, changes in the perceived likelihood that a crime will be solved may lead a higher fraction of victimizations to be reported to the police. In this paper, three data sets are employed to measure the magnitude of this reporting bias. While each of these analyses is subject to individual criticisms, all of the approaches yield similar estimates. Reporting bias appears to be present but relatively small in magnitude: each additional officer is associated with an increase of roughly five Index crimes that previously would have gone unreported. Taking reporting bias into account makes the hiring of additional police substantially more attractive from a cost–benefit perspective but cannot explain the frequent inability of past studies to uncover a systematic negative relationship between the size of the police force and crime rates.  相似文献

This paper describes the monitored outpatient treatment program for Psychiatry Security Review Board (PSRB) clients in the largest single community treatment agency in the Oregon system. We describe 161 persons referred to this agency for evaluation and treatment. Ninety-one PSRB clients received treatment and of this group 51% had their conditional release revoked by the PSRB. The most frequent cause of revocation was noncompliance with treatment. There were only 11 crimes committed during the study period, four of which were in the felony range. The majority of PSRB clients are chronically mentally ill persons. We discuss both the treatment approach and our results in light of a recently published research agenda for insanity acquittees.  相似文献
