Autoerotic asphyxia: part I

Fatal autoerotic asphyxia refers to death during solitary sexual activity with self-induced asphyxiation meant to be brief and reversible. However, an unexpected fatality results from a failure of a release mechanism apparatus. The large majority of victims of autoerotic death are Caucasian males between the second and fourth decade. While autoerotic death may encompass a myriad of other means of achieving sexual gratification, which includes asphyxia by plastic bag or inhalation of noxious chemicals, the most common method is by ligature about the neck. This study presents a 9-year retrospective review of deaths due to autoerotic asphyxia, specifically ligature asphyxia, in Kentucky between 1993 and 2001. Of the sixteen victims, all were Caucasian males between the ages of 14 and 59 years, with a mean age of 38.3 years. Cross-dressing was a feature in 4 cases. A thorough review of the decedent's background, meticulous scene investigation, and complete postmortem examination may shed light on the mechanism and psychosocial predisposition associated with autoerotic asphyxia.     

Atypical autoerotic death: part II

Autoerotic fatalities encompass a wide array of means and mechanisms used to attain sexual gratification. The most commonly encountered autoerotic practice, specifically, autoerotic asphyxia, denotes death resulting from failure of a release mechanism of the apparatus designed to attain cerebral hypoxia for heightened arousal. Historically, the majority of victims of autoerotic death are Caucasian males under the age of 30. While autoerotic death is most often associated with a constrictive cervical ligature tied to either other parts of the victim's body or to an inanimate object such as a door, several other methods have been reported. These modalities include ligature around the thorax or abdomen, plastic bags covering the face, electrical current, inhalation of a toxic gas or chemicals, or partial or total submersion, known as aquaerotic asphyxiation. This study highlights 11 cases of atypical autoerotic death, including asphyxia with a plastic bag, electrocution, and inhalation of butane and nitrous oxide (N2O). Whereas the manner of death in the majority of autoerotic death cases is deemed accidental, we present and analyze unique and equivocal cases representing 4 different manners of death: accident, natural, suicide, and homicide. The 11 victims were all Caucasian and between the ages of 17 and 55. Ten decedents were males, 1 female. A comprehensive investigation incorporating a thorough scene analysis, gathering of the victim's history, and complete postmortem examination is necessary to elucidate both the cause and manner of death in these atypical cases.     

Evaluation of the Cozart RapiScan drug test system for opiates and cocaine in oral fluid

The purpose of this study was to evaluate the efficiency of the Cozart RapiScan (CRS) drug test system for detecting opiates and cocaine in oral fluid. Oral fluid samples were collected using the Cozart RapiScan collection system from 358 donors who were receiving treatment for their addiction and were monitored for drug misuse. A further 103 oral fluid samples were collected from volunteer donors who were not drug users. The samples were analyzed in the laboratory using the two-panel Cozart RapiScan cartridge for opiates and cocaine and confirmed using gas chromatography-mass spectrometry (GC-MS). The samples were stored frozen at -20 degrees C until analysis by GC-MS. The overall accuracy of the CRS for both opiates and cocaine was 100%. Samples spiked at 50% above and below the cut-off consistently gave negative and positive results respectively. A total of 88 samples were positive for various opiates and 111 samples were positive for cocaine and/or its metabolites. The CRS for opiates and cocaine in oral fluid, using a cut-off of 30 ng/mL morphine or benzoylecgonine equivalents in neat oral fluid, had overall efficiencies of 98% and 99%, respectively, versus GC-MS. A series of potential adulterants of oral fluid were evaluated and shown not to alter the outcome of the test result.     

Validation of the Cozart microplate EIA for analysis of opiates in oral fluid

The purpose of this study was to determine the performance characteristics of the Cozart microplate EIA for detecting opiates in oral fluid from patients in a drug misuse treatment program. Oral fluid samples were collected using the Cozart RapiScan Collection System from 216 donors who were receiving treatment for their addiction and were monitored for drug abuse. A further 40 oral fluid samples were collected from volunteer donors who were not drug users. The samples were analyzed in the laboratory by using the Cozart microplate EIA for opiates and confirmed using gas chromatography-mass spectrometry (GC-MS). The samples were stored frozen until analysis by GC-MS. The intra-assay precision for the Cozart microplate oral fluid EIA for opiates over 40 assays was 0.43% to 9.13% CV (within assay) and 2.9% to 9.1% CV (within day). A total of 109 samples were positive for various opiates. The Cozart microplate EIA for opiates in oral fluid, using a cut-off of 30 ng/ml morphine equivalents in neat oral fluid, had a sensitivity of 99.1 +/- 2.1% and a specificity of 94.4 +/- 2.2% versus GC-MS. A series of potential adulterants of oral fluid were evaluated and shown not to alter the outcome of the test result.     

Predictors of Child Abuse Potential Among Military Parents: Comparing Mothers and Fathers

The present study examines the predictors of child abuse potential for at-risk fathers and mothers serving as active duty Army members and their spouses. Although fathers are perpetrators of child physical abuse and neglect in a substantial portion of reported cases, what is known about factors associated with child maltreatment comes almost exclusively from studies of perpetrating mothers. Thus, the inclusion of a large sample of fathers in the present study makes a significant contribution to the extant literature. Participants were 175 fathers (93% active-duty) and 590 mothers (16% active duty) of young children enrolled in an Army-sponsored home visitation program. Regression analyses indicated that there were both common and unique predictors of child abuse potential for mothers and fathers. Common predictors included depression, parental distress, and family conflict. Low family expressiveness was predictive only for fathers, whereas marital dissatisfaction, low social support, and low family cohesion were predictive only for mothers. Possible reasons for these gender differences and the implications of these results for child maltreatment interventions are discussed.     

Home as a locus of work and career

In response to contemporary work environments and the increased availability of technologies, individuals and organizations are experimenting with alternate forms of work located in the home. This article examines the complex and creative intersection of "home" and "work." From 1990-1997, the number of individuals classified as home-based workers nearly tripled, reaching 9.3 million. Areas explored in the present study include emerging patterns in the work-at-home arena, the critical success factors that facilitate development of work and career in the home, and the opportunities afforded to individuals, families and communities when home is the locus of work. Directions for future research and debate in this area are presented.     

Longitudinal Outcomes for Youth Receiving Runaway/Homeless Shelter Services

This research examined outcomes and use of specific types of services 6 weeks, 3 and 6 months post-discharge for a large sample of runaway/homeless youth using crisis shelter services. Data were collected for 371 runaway/homeless youth using emergency shelter and crisis services at eleven agencies across a four-state midwestern region. Outcomes were assessed for runaway behavior, family relationships, substance use, school behavior, employment, sexual behavior, and self-esteem. Additionally, the impact of services on outcomes was assessed. Findings indicated that although youth achieved a wide variety of positive outcomes 6 weeks post-discharge, there were signs of attenuation of certain outcomes by the 6 month follow-up. Service use after discharge did not demonstrate a strong impact on maintaining outcomes. The substantive findings reported here present encouraging evidence for providers of services for runaway/homeless youth. Crisis shelter services appear to facilitate broad-based short-term gains, but do not appear sufficient to maintain these gains over an extended period.
