AIDS fatalities in Hamburg (status: February 1985)--legal medicine aspects

The registration of patients with acquired immune deficiency syndrome (AIDS) and AIDS deaths is centralized for medical research. A short review of the epidemiological state of AIDS in Hamburg is given (situation as of February 1985), and the autopsy results of seven postmortem examinations are referred to. Kaposi's sarcoma was seen in four patients and opportunistic infections in all cases, especially as a result of Pneumocystis carinii and cytomegalovirus. Due to the constellation of groups with an increased risk of acquiring AIDS--homosexual males, intravenous drug abusers and prostitutes--forensic implications have to be expected.     

First‐generation genetically modified organisms in agriculture

• The introduction of genetically modified (GM) crops has led to a plethora of policy issues based around consumer perceptions. In this paper, we present a general framework for analysing the economic impact of GM crops that incorporates supply benefits, market segmentation and the additional segregation costs imposed by market segmentation. We then give the results of five case studies of GM crops based on this general model. Consumers not sensitive to GM content and farmers in certain regions who can use GM seed to reduce costs benefit from the introduction of GM varieties, while consumers sensitive to GM content and producers in certain regions who cannot use GM seed to reduce costs are worse off.

Successful extraction of human genomic DNA from serum and its application to forensic identification

We report here on the successful extraction of human genomic DNA from a serum sample in a forensic case. The extracted DNA was successfully used for the identification of remains presumably immersed for more than three weeks for which the only comparison sample was a 250-microL serum aliquot kept frozen in a laboratory. The analysis made it possible to identify a second victim as the daughter of the first.     

Juveniles' Competence to Stand Trial: A Comparison of Adolescents' and Adults' Capacities as Trial Defendants

Abilities associated with adjudicative competence were assessed among 927 adolescents in juvenile detention facilities and community settings. Adolescents' abilities were compared to those of 466 young adults in jails and in the community. Participants at 4 locations across the United States completed a standardized measure of abilities relevant for competence to stand trial (the MacArthur Competence Assessment Tool—Criminal Adjudication) as well as a new procedure for assessing psychosocial influences on legal decisions often required of defendants (MacArthur Judgment Evaluation). Youths aged 15 and younger performed more poorly than young adults, with a greater proportion manifesting a level of impairment consistent with that of persons found incompetent to stand trial. Adolescents also tended more often than young adults to make choices (e.g., about plea agreements) that reflected compliance with authority, as well as influences of psychosocial immaturity. Implications of these results for policy and practice are discussed, with an emphasis on the development of legal standards that recognize immaturity as a potential predicate of incompetence to stand trial.     

Does It Take a Village? Policing Strategies and Fear of Crime in Latin America

How can policymakers reduce public fear of crime in Latin America? This study compares the effectiveness of “zero tolerance” and community‐based policing strategies in Argentina, Brazil, and Chile. At the micro level, it assesses the links between fear of crime and social identity characteristics, contextual factors, the media, community participation, and other insecurities. It finds that citizens' economic, political, and social insecurities are the main determinants of their fear of crime. At the macro level, the study compares levels of public insecurity and finds that cities that employ community‐based strategies to fight crime register lower levels of public fear of crime.     

Ethnic Differences in Trajectories of Family Cohesion for Mexican American and Non-Hispanic White Adolescents

This study examined gender, family structure, SES and language usage as predictors of cultural orientation and family cohesion. Ethnic differences in trajectories of family cohesion were tested within a hierarchical linear modeling framework. The sample consisted of 4156 adolescent respondents, measured at three time points during three consecutive years. The three study groups consisted of Mexican Americans oriented to Mexican culture (N = 738), Mexican Americans oriented to majority American culture (N = 867), and Non-Hispanic Whites (N = 2551). Family cohesion was assessed using the cohesion subscale of the Family Adaptability and Cohesion Scale (FACES III). Analyses consisted of hierarchical linear modeling (HLM) in which a linear trajectory of family cohesion for the three groups was computed followed by a test for the effects of ethnicity with the inclusion of control variables. Thus, ethnic differences in the trajectories of family cohesion over time were examined. Neither group of Mexican Americans was significantly different from Non-Hispanic Whites in initial status. However, Mexican Americans oriented to Mexican culture showed a significant increase in family cohesion at mid adolescence. Judith C. Baer is an Associate Professor at Rutgers University. She received her Ph.D. in Social Work from the University of Houston. Her major research interests include the study of adolescent development within the contexts of culture, and family, adolescent sexual risk taking, and the nosology of mental disorders. Mark F. Schmitz is Clinical Assistant Professor at Temple University. He received his Ph.D. in sociology at Iowa State University. His major research interest involves the use of several large epidemiologic datasets for an extensive examination of the empirical basis for the diagnostic criteria of various DSM-IV mental disorders. He also is involved in research on cultural issues in child development and family processes.     

Suicide of an adolescent girl with sodium nitrite ordered on the internet

Nitrites are commonly used in the chemical, pharmaceutical, and food industries. Recently, they have been identified in cases of voluntary intoxication. We report the case of a 13-year-old girl who was found lifeless on her bed next to a glass containing a white powder and a bottle containing a white powder with a moistened appearance. External examination and autopsy revealed a nonspecific asphyxia syndrome, which was confirmed by the pathological analysis. Analysis of the samples revealed metoclopramide in the peripheral blood at a concentration of 0.402 mg/L (LC–HRMS). An analysis of the gastric contents was carried out after sodium nitrite was detected in the powders found near the body (Raman spectrometry). Nitrites were found in the gastric fluid at a concentration of 30.9 mg/L. Death occurred secondary to anoxia, following ingestion of nitrites; suicide kits are available on the web and nitrites are relatively easy to source and inexpensive. Nitrites are delivered in powder form to be dissolved in liquid, which may then be consumed with metoclopramide (or an alternative anti-emetic drug) to maximize absorption and reduce emesis. The toxic effect of nitrites lies in their oxidizing power, causing the transformation of hemoglobin into methemoglobin, which, when it accumulates, induces tissue anoxia resulting in death. There has been an alarming increase in the number of cases linked to suicide using nitrites or a nitrite suicide kit. The fact that nitrites are readily available online underscores the importance of establishing effective preventive measures such as limiting the access and use of this chemical.
