Recovery and identification of the victims of the Ehime Maru/USS Greeneville collision at sea

This paper describes the recovery and identification of crew members lost during a collision at sea. On 9 February 2001, south of Honolulu, Hawaii, the Japanese fishing training boat, Ehime Maru was struck by the USS Greeneville (SSN 772), a Los Angeles-class fast attack submarine. Witnesses estimate that the vessel sank within 5-10 min after the collision. Nine of the 35 crew members remained unaccounted for after rescue procedures were completed. The U.S. Navy attempted the unprecedented procedure of moving the boat from a depth of 610 m (2000 ft) into shallower waters so that the missing could be located and recovered. Eight of the nine crew members were recovered and identified by their dental records.     

Recent developments in medicine and law

This article focuses on certain noteworthy legislation and cases affecting medicine and law during the period September 1, 2001, to August 31, 2002. It does not attempt to discuss every case or piece of legislation, but instead seeks to summarize some of the more significant developments in this area of law.     

A rapid test for heroin (3,6-diacetylmorphine) based on two chemiluminescence reactions

A rapid method for screening drug seizure samples for 3,6-diacetylmorphine (heroin), which consists of a simple hydrolysis procedure and flow-injection analysis with two chemiluminescence reagents, is described. Before hydrolysis, 3,6-diacetylmorphine evokes an intense response with a tris(2,2'-bipyridyl)ruthenium(III) reagent (prepared by dissolving the perchlorate salt in acetonitrile), and a relatively weak chemiluminescence response with a second reagent: potassium permanganate in an aqueous acidic polyphosphate solution. However, the permanganate reagent is extremely sensitive toward the hydrolysis products of 3,6-diacetylmorphine (i.e., 6-monoacetylmorphine and morphine). Some compounds commonly found in drug laboratories may cause false positives with tris(2,2'-bipyridyl)ruthenium(III), but do not produce the markedly increased response with the permanganate reagent after the hydrolysis procedure. The combination of these two tests therefore provides an effective presumptive test for the presence of 3,6-diacetylmorphine, which we have verified with 14 samples obtained from a forensic science laboratory.     

Quantitation of atenolol, metoprolol, and propranolol in postmortem human fluid and tissue specimens via LC/APCI-MS

Hypertension is a growing medical concern in the United States. With the number of Americans suffering from hypertension increasing, the use of antihypertensives such as beta-blockers is increasing as well. In fact, three beta-blockers - atenolol, metoprolol and propranolol - were among the 200 most prescribed medications in the United States in 2003. Pilots that successfully manage their hypertension can remain certified to fly. The Federal Aviation Administration currently designates approximately 8% of active pilots as "hypertensive with medication". The Civil Aerospace Medical Institute (CAMI) performs toxicological evaluation on victims of fatal aviation accidents. At CAMI beta-blockers are analyzed using gas chromatography with mass spectrometric detection. We have, however, recently developed a liquid chromatography with mass spectrometric detection (LC/MS) method for the simultaneous quantitation of three commonly prescribed beta-blockers, atenolol, metoprolol and propranolol. One advantage of our LC/MS method is the specificity provided by an ion trap MS. Utilizing an ion trap MS, we were able to conduct MS/MS and MS/MS/MS on each analyte. This method also eliminates the time-consuming and costly derivitization step necessary during GC/MS analysis. Additionally, by utilizing this novel method, any concerns about beta-blocker metabolite and/or sample matrix interference are eliminated. The limits of detection for this method ranged from 0.39 to 0.78 ng/mL and the linear dynamic range was generally 1.6-3200 ng/mL. The extraction efficiencies for each analyte ranged from 58% to 82%. This method was successfully applied to postmortem fluid and tissue specimens obtained from victims of three separate aviation accidents.     

Drug and alcohol use as determinants of New York City homicide trends from 1990 to 1998

In this population-level study, we analyzed how well changes in drug and alcohol use among homicide victims explained declining homicide rates in New York City between 1990 and 1998. Victim demographics, cause of death, and toxicology were obtained for all homicide (N = 12573) and accidental death victims (N = 6351) between 1990 and 1998 from the Office of the Chief Medical Examiner of New York (OCME). The proportion of homicide and accident decedents positive for cocaine fell between 1990 and 1998 (13% and 9% respectively); the proportion of homicide and accident decedents positive for opiates and/or alcohol did not change significantly. Changing patterns of drug and alcohol use by homicide victims were comparable to changing patterns of drug and alcohol use in accident victims, suggesting that changes in drug and alcohol use among homicide victims between 1990 and 1998 cannot solely explain the decline in NYC homicide rates.     

When Am I My Group? Self-Enhancement Versus Self-Justification Accounts of Perceived Prototypicality

The tendency to view the self as a prototypic member of a group is thought to be at the foundation of many social psychological phenomena. Two opposing accounts of perceived prototypicality have been suggested in the psychological literature. The self-justification account portrays this as a defensive tendency that occurs in response to threatened group status. The self-enhancement account portrays this as a strategic tendency to associate the self with positively viewed groups. These competing views were tested using both a minimal group (Study 1) and a naturalistic group (Study 2). Both studies showed that perceived prototypicality increased with increasing group status. Moreover, the effect of status was moderated by group importance (Study 1) and behavioral choice (Study 2). Both interaction patterns supported the self-enhancement view, suggesting that people view themselves as prototypic group members when doing so will promote a positive identity. These findings contradict common statements in the social identity literature.     

Reports of Intimate Partner Violence Made Against Police Officers

The purpose of this case control study was to compare police officers (n = 106) from a large urban police force, charged with committing intimate partner violence (IPV) with officers who were not charged (n = 105), in order to identify risk factors for IPV. We also compared the frequency, type, and final disposition of IPV reports filed against police officers before and after the enactment of the 1994 Violence against Women Act (VAWA). Officers accused of IPV were more likely to be members of a minority, on the force more than 7 years and assigned to a high crime district. No major differences on intake baseline MMPI scores were noted between cases and controls. A significant increase in reports of IPV was noted after the enactment of VAWA; the rate changed from 0.2/100 to 1.2/100 person years, although there were too few pre-1994 reports to compare further. Most of the final dispositions of the cases resulted in cases closed due to unsupported testimony from victims. An erratum to this article is available at .
