Cerebral ischemia or post traumatic thrombosis of the A. carotis occuring to a car driver (author's transl)]

A short while after leaving a public-house a 71 year old man as the driver of his car was involved in a head-on collision with another car. On admission to a hospital he was unconscious with a distinct debility for the left side of his body and showed a changing anisocoria. Angiography of the right carotid artery revealed an occlusion. It was suspected that this was the terminal state of a generalized arteriosclerotic occlusion which was considered being the reason for the accident. The autopsy-findings showed, however, a posttraumatic thrombosis (whiplash-trauma of the cervical vertebral column) of the right arteria carotis and of the right arteria vertebralis with thromboembolia in a small pontine artery with an infarct-like ischemic softening. The differentiation from an apoplexia is of importance for the differential diagnosis.     

Actors at Large-Scale Accidents: Lessons from the Bravo and Three Mile Island Accidents

This paper explores organizational issues raised via a comparison of the Bravo oil blowout in the North Sea and the Three Mile Island nuclear accident in Pennsylvania. The organizations involved, their interconnections and interests in each accident are compared. Six actor types are used as a classification system for framing the comparison. The underlying issues bearing on allocation of effort to pre-accident planning are also noted. Finally, a framework from this effort is used for guiding the planning of operations for future accidents.     

Parent Relationships,Emotion Regulation,Psychosocial Maturity and College Student Alcohol Use Problems

This study tested associations between problems in parent-youth relationships and problems with alcohol use among college students (N = 1592) using structural equation modeling. Hypotheses were that relationships between both substance-specific parenting factors (parental drinking) and non-substance-specific parenting factors (parental intrusive control and lack of support) and college student drinking behaviors would be mediated by the developmental tasks of managing difficult emotions and establishing a mature psychosocial identity. Sex, ethnicity and age were entered as control variables in the analyses and were tested for moderating effects. Results showed that the unconstrained model for males and females differed significantly from a model in which the two groups were constrained to be similar. Among young women, emotion regulation and psychosocial maturity were partial mediators of the effects of parent problems on alcohol use problems. Among young men, parent problems were indirectly related to alcohol use problems through emotion regulation. Implications for alcohol use prevention activities on college campuses are discussed.

A study of various morphologic variables and troponin I in pericardial fluid as possible discriminators of sudden cardiac death

Pathologists frequently examine victims of sudden cardiac death. In some cases, a firm diagnosis of cardiac-related death can be made based on conclusive gross and histologic findings. In many other cases, we find evidence supportive of, but not diagnostic of, cardiac death (e.g., atherosclerotic coronary artery disease, cardiomegaly, myocardial scarring). A final cohort consists of cases of sudden death with minimal to mild cardiac disease, no other significant pathology, and negative toxicologic studies. This prospective study compared 38 cardiac-related deaths with 52 control cases with respect to concentrations of pericardial cardiac troponin I (cTnI), heart weight, evidence of old and/or recent myocardial injury, and presence of significant coronary artery disease. The influence of documented chest trauma and/or perimortem cardiopulmonary resuscitation (CPR) on levels of cTnI was also analyzed. Even though median cTnI levels were significantly higher in cardiac deaths than in controls (p = .003), cTnI was not found to be a significant predictor of cardiac deaths, as determined by discriminant analysis (p = .52). Heart weight >500 g, evidence of old and recent myocardial injury, and significant coronary artery disease were seen statistically more often in cardiac deaths than in controls (p < or = .005 in each case), and median age was significantly higher in cardiac deaths than in controls (p = .001). Based on a stepwise logistic regression model, significant coronary artery disease, old and recent myocardial injury, and heart weight >500 g were found to contribute significantly to the prediction of cardiac death. Finally, neither chest injury nor CPR significantly affected concentrations of cTnI in pericardial fluid. These data confirm that the presence of acute and remote myocardial injury, significant coronary artery disease, and cardiomegaly (heart weight >500 g) strongly supports the diagnosis of a cardiac-related death. In contrast to a recently published report, we do not find that elevated concentrations of cTnI in pericardial fluid are strong indicators of cardiac-related deaths using our methodology.     

The relationship of observed maternal behavior to questionnaire measures of parenting knowledge,attitudes, and emotional state in adolescent mothers

Although relationships have been found between maternal psychological characteristics and cognitive and emotional outcomes in children, the behaviors which may mediate these relationships are seldom examined. This is especially true for adolescent mothers, whose children are thought to be at high risk for adverse outcomes. In this study, adolescent mothers in two special programs completed questionnaires measuring perception of the newborn (Neonatal Perception Inventory), knowledge of influences on child development (Infant Caregiving Inventory), and emotional state (General Health Questionnaire); they were also systematically observed while interacting with their infants in a naturalistic situation. Specific maternal behaviors were found to vary with the age of the mother and of the baby. Mothers with neutral or negative perceptions of their infants touched them less than did mothers with positive perceptions. Degree of emotional disturbance was inversely related to the amount of time that the mother looked at her infant while in physical contact.This research was supported in part by NIH Biomedical Research Support Grant No. BRS 507 RR 05445-19 to Johns Hopkins University School of Hygiene and Public Health.Received her Sc.D. in mental hygiene (comparative behavior) from Johns Hopkins University.

Transitions in relationship style from adolescence to young adulthood

Literature on friendships of adolescents and young adults suggests important gender and age-related differences. In a study of transitions in relationship style from middle adolescence (high school) to late adolescence (college), 300 students described their relationship with the person who was closest to them, either same or other sex. Four relationship styles were characteristic: integrated (high friendly and high intimate), intimate (high intimate and low friendly), friendly (high friendly and low intimate), and uninvolved (low intimate and low friendly). Women's more intimate styles of relating, as compared to men's more uninvolved styles, suggested that women developed earlier competence at intimate relating than did men. Viewed as particularly important were the college women's close friendships with those of the same gender, an experience uncharacteristic of adolescent men in high school and college. Results were discussed in terms of Erikson's stages of development and Sullivan's concept of the chum.Received Ph.D. in social psychology from the University of Colorado. Major interests are relationship style, intimacy development, and transitions to adulthood.
