The psychological impact of stalking on female undergraduates.

This study examined the psychological impact of stalking upon female undergraduates, a population previously determined to experience a surprising stalking prevalence rate. Despite common understanding that stalking has deleterious effects, there have been no previous efforts to systematically assess them with standardized measures. Thirty-six female stalking victims were compared with 43 females who had been harassed and 48 controls. Psychological impact was assessed with the Posttraumatic Stress Disorder Scale, the Symptom Checklist-90-R, and the Self-Report Interpersonal Trust Scale. Stalked subjects endorsed significantly more PTSD symptoms and with greater severity than the harassed or control subjects. Stalked subjects also had significantly higher scores on several subscales of the SCL-90, and had significantly higher positive symptom totals and distress indices.     

Morphine perfused rabbits: a tool for experiments in forensic entomotoxicology

In order to establish an animal model for entomotoxicological studies, the kinetics of morphine elimination from blood after a single intravenous injection of morphine and the concentration of morphine in tissues following a continuous perfusion were studied. The aim of these experiments was to obtain controlled morphine tissue concentrations similar to those encountered in fatal human heroin overdoses. These tissues can be used as a food source for developing fly larvae in entomotoxicological studies. In the single injection experiment, seven rabbits were administered 1 or 2 mg/kg body weight of morphine chlorhydrate via the main ear artery. Blood samples of 200 microL were removed regularly via a catheter. Morphine concentration was determined using RIA techniques. Morphine was found to be first rapidly distributed and then slowly eliminated, following a two-exponential equation. Elimination of morphine from blood can be described as a two-compartment model. Constants of the equation were determined using the Kaleidagraph program. Using those constants, the main pharmacokinetics parameters were calculated. Results of these parameters showed the following: clearance from 13.3 to 16.2 L.h.1, half-life of the distribution phase from 0.6 to 0.9 min, and half-life of the elimination phase from 21 to 26 min. These results were used to calculate the rate of perfusion of morphine for rabbits to obtain desired, controlled, and constant concentrations of morphine in tissues. In the second experiment, three rabbits received a perfusion of morphine intravascularly at a rate of 2 mg/kg/h for a period of 3 h. These rabbits were sacrificed and analyses performed on several abdominal and thoracic organs. Results showed that the concentrations of morphine differed according to the organ analyzed, but were reproducible for organs between animals. These concentrations were similar to those normally encountered in cases of human death due to heroin overdoses.     

Methamphetamine-related deaths in San Francisco: demographic, pathologic, and toxicologic profiles

A study was undertaken to develop demographic, toxicologic, and pathological profiles of methamphetamine-related deaths. Anatomic and toxicologic findings in 413 deaths where methamphetamine was detected were compared with findings in a control group of 114 drug-free trauma victims. The number of cases per year did not change significantly over the course of the study. Mean age was 36.8 years, but 11% were over the age of 50. Decedents were overwhelmingly male (85.2%) and Caucasian (75%). Blood concentrations of methamphetamine and amphetamine were indistinguishable in cases where methamphetamine was related to the cause of death (MR) and cases where it was not (non-MR) (2.08 vs. 1.78 mg/L, p = 0.65, and 0.217 vs. 0.19 mg/L, p = 0.82). Coronary artery disease, ranging from minimal to severe multivessel, was identified in 79 of the 413 drug users, but in only six of the 114 drug-free controls (p = 0.0004), and MR decedents had enlarged hearts compared with controls. There were also ten cases of subarachnoid and intracranial hemorrhage in the MR group. Abnormalities of the liver (34%) and lungs (24.7%) were frequent. In 65% of these cases, death was due to accidental methamphetamine toxicity. In the remaining cases, methamphetamine was an incidental finding. We conclude that, in our jurisdiction, neither the rate of detection nor the number of methamphetamine deaths has increased significantly in the past 13 years. Decedents are almost all Caucasian males, and many were approaching middle-age. Methamphetamine use is strongly associated with coronary artery disease and with subarachnoid hemorrhage.     

Use of combined frequencies for RFLP and PCR based loci in determining match probability

Statistical analysis was performed on a subset of the Pennsylvania State Police Caucasian, African American and Hispanic database for the purpose of determining Hardy-Weinberg equilibrium and associations across the RFLP loci D1S7, D2S44, D4S139, D5S110, D10S28 and D17S79 and the PCR-based loci HLA-DQA1, LDLR, GYPA, HBGG, D7S8 and Gc. Overall, the statistical results are consistent with a population in equilibrium both within and between loci. The assumption for independence is valid.     

The law and the public's health: a study of infectious disease law in the United States

Law plays crucial roles in the field of public health, from defining the power and jurisdiction of health agencies, to influencing the social norms that shape individual behavior. Despite its importance, public health law has been neglected. Over a decade ago, the Institute of Medicine issued a report lamenting the state of public health administration, generally, and calling, in particular, for a revision of public health statutes. The Article examines the current state of public health law. To help create the conditions in which people can be healthy, public health law must reflect an understanding of how public health agencies work to promote health, as well as the political and social contexts in which these agencies operate. The authors first discuss three prevailing ways in which the determinants of health are conceptualized, and the political and social problems each model tends to create for public health efforts. The analysis then turns to the core functions of public health, emphasizing how law furthers public health work. The Article reports the results of a fifty-state survey of communicable disease control law, revealing that few states have systematically reformed their laws to reflect contemporary medical and legal developments. The Article concludes with specific guidelines for law reform.     

Fatal child abuse (caused by physical violence) in Germany during 1 January 1985 to 2 October 1990. Results of a multicenter study]

No reliable data are available on cases of lethal child abuse (by active force) in the area of Federal Republic of Germany prior to reunification (the former West Germany). In a multicenter study we therefore examined the police and court records for such cases occurring in the period 1 January 1985 to 2 October 1990 in nearly the entire area of Federal Republic of Germany. RESULTS: The study center received information on 58 cases of lethal child abuse. Extrapolated to all institutes of legal medicine, this corresponds to 62 cases in all of West Germany in the period studied. An approximately equal number of unreported cases should be added to this figure. Including unreported cases, at least 20 cases of lethal child abuse occurred per year; thus only one in every two cases ever came to light. Almost two thirds of the victims were younger than one year old. At autopsy 59% exhibited signs of repeated abuse at autopsy. By far the most common cause of death was direct impact from a blunt object, usually to the head. Mostly, the male person to whom the victim relates most closely (father, stepfather, partner of the mother) has killed the child. Twenty-one of the 74 persons charged saw the charges against them dropped or were acquitted due to lack of evidence; 51 received sentences ranging from one year probation to life. In the remaining two cases the outcome of the trial was unknown. Signs of abuse were readily apparent at autopsy in almost all cases. The high number of unreported cases underscores the need to educate medical students and practicing physicians to be on the look-out for signs of abuse and argues for an increase in the rate of autopsy.     

Alcohol content of beer and malt beverages: forensic consideration

Beer consumption is commonly an issue in a medico-legal setting, requiring estimates either of a likely blood alcohol concentration (BAC) for a given pattern of consumption or vice versa. Four hundred and four beers and malt beverages available for sale in the State of Washington were tested by gas chromatography for their alcohol content. Considerable variability in the alcoholic strength was found, even within the same class. Overall the range of concentrations was 2.92%v/v to 15.66%v/v. The mean alcohol concentration for ales was 5.51%v/v (SD 1.23%v/v), and for lagers, 5.32% (SD 1.43%v/v). Some specialty brews had characteristically higher or lower mean concentrations: ice beers 6.07%v/v, malt liquor 7.23%v/v, light beer 4.13%v/v, seasonal ales 6.30%v/v. Six brands of lager and four light beers account for the majority of all beer sales in the United States, and the mean alcohol concentration for these products was measured as 4.73%v/v and 4.10%v/v respectively. Few of the beers (17%) were labeled with respect to alcohol content, and in some cases, there was a significant disparity between the concentration listed on the label, and the measured alcohol concentration. Toxicologists need to exercise caution when performing Widmark type calculations, using all available information to select the most appropriate estimate for alcoholic strength of a beer or malt beverage.     

Wischnewski ulcers and acute pancreatitis in two hospitalized patients with cirrhosis, portal vein thrombosis, and hypothermia.

Accidental hypothermia has been described in the forensic literature but reports of occurrence in hospitalized patients are rare. Associated anatomic lesions include acute hemorrhagic pancreatitis and characteristic acute gastric ulcers termed Wischnewski ulcers. We report here two patients with cirrhosis and ascites; one also had hepatocellular carcinoma. Portal vein thrombosis, acute hemorrhagic pancreatitis and Wischnewski ulcers were present in both. The clinical records documented hypothermia that progressed over several days. Temperature nadirs of 31.0 degrees C (87.8 degrees F) and 32.2 degrees C (90.0 degrees F) were recorded in each patient, respectively, one day before death, although each transiently reached temperatures that did not register on standard monitoring devices. This is the first report that chronicles antemortem body temperatures in hypothermic patients with Wischnewski ulcers and pancreatitis at autopsy. Also, the association of these findings with portal vein thrombosis and cirrhosis has not been previously described. We discuss this constellation of findings with regard to possible mechanistic interrelations.
