The decline in the incidence of sudden infant death syndrome (SIDS) and recent recommendations regarding the differentiation of SIDS and child abuse has generated speculation that some cases of infanticide were misdiagnosed as SIDS. The aims of this study were to determine the change in incidences and proportions of postneonatal deaths from all causes, SIDS, and infanticide in California over an 18-year interval encompassing years before and after the Back to Sleep campaign. Selected postneonatal mortality data from 1981 through 1998 obtained from the California Department of Health Services were analyzed and graphically displayed. The total postneonatal mortality and incidence of SIDS deaths per 100,000 live births decreased 45% and 66%, respectively, during the study interval; the incidence of infanticide remained low. The ratio of infanticide to SIDS increased from 4.3 per 100 in 1981 to 10.2 per 100 in 1998. Infanticide deaths, as a percentage of the total number of postneonatal deaths, increased slightly from the first to the second half of the study interval but never rose above 3.2%. It is concluded that this increased percentage is due to a decrease in SIDS deaths and not to an actual increase in infanticide deaths.  相似文献

Age determination is a major field of interest in forensic anthropology. Among the different methods based on macroscopic skeletal study, the Suchey-Brooks method, which analyzes the pubic symphysis, is one of the most reliable. We applied the Suchey-Brooks method to three-dimensional computed tomographic reconstructions of the pubic symphysis. We demonstrated excellent agreement between the results of analysis of bone samples and those of the three-dimensional images, in particular regarding ridges of the articular surface and delimitation of the extremities. The accuracy of age estimation did not significantly differ (Wilcoxon test) between the Suchey-Brooks method applied to bones and the same method applied to CT images. Using high-quality images, this approach seems as reliable as the standard Suchey-Brooks method and offers several advantages: no bone preparation, no damage to bone material, and the possibility of application to living individuals.  相似文献

In recent years much research effort has been directed at assessing psychopathic personality disorder in juveniles and at devising structured assessment procedures for recidivism risk. Clinicians, however, are often reluctant to incorporate this recent research into their practice. While accepting the importance of a better understanding of the development of psychopathic personality disorder, we discuss three arguments against the uncritical application of current research findings concerning the disorder and its clinical value as a risk factor. We briefly review empirical evidence for the role of the disorder in risk assessment. A developmental psychopathology argument against current thinking about juvenile psychopathic personality disorder, and a criminological argument against risk assessment but in favor of a desistance approach to delinquency are discussed.  相似文献

This study examined the effectiveness of an abbreviated version of the Structured Interview of Reported Symptoms (SIRS-A) in identifying malingered mental illness. The SIRS-A is comprised of 69 items drawn from the SIRS (R. Rogers et al. 1992, SIRS: Structured Interview of Reported Symptoms: Professional Manual. Odessa, FL: Psychological Assessment Resources, Inc.), substantially reducing the administration time. A simulation design was used with three samples; 87 psychiatric outpatients who responded honestly were compared to 29 community-dwelling adults and 24 psychiatric patients instructed to malinger psychopathology. The SIRS-A generated sensitivity comparable to or exceeding that of the SIRS normative data, but specificity was poorer; many genuinely impaired patients were misclassified as malingering. Although these findings suggest the SIRS-A may be an effective means to assess malingering in psychiatric populations, further research assessing the reasons for the elevated false positive rates is necessary.  相似文献

This study examines peritraumatic (and posttrauma) responses in a sample of female crime victims who had been sexually or physically assaulted within the previous 2 months. Women were interviewed about their emotional and behavioral responses during the trauma and assessed for posttraumatic stress disorder and depression symptomatology. Results indicate that women experience a wide range of behavioral and emotional responses during a traumatic event and that these responses have implications for posttrauma adjustment. Women who experienced behaviors typical of a freeze response are more likely to have a greater degree of symptomatology after the assault. Peritraumatic emotions, other than fear, such as sadness, humiliation, and anger, also appear to be related to posttrauma depression symptoms. These findings highlight the necessity of exploring the full range of possible reactions during a trauma.  相似文献
