A soft-tissue calcification: differential diagnosis and pathogenesis

An autopsy of a 72-year-old white male revealed a 30.5 x 5.1 cm vertically aligned heterotopic ossification just deep to a 30.5 cm midline abdominal scar. The ossified mass was determined to be a heterotopic ossification or myostitis ossificans (MO) traumatica resulting from an abdominal surgical incision during life. While, MO traumatica is relatively common accounting for roughly 60-75% of patients with soft-tissue ossification, heterotopic ossification of abdominal incisions are relatively rare and thus infrequently reported. This article details the manifestation of this relatively large heterotopic bone and provides a comprehensive review of the literature and pathogenesis of this unusual ossification. A review of the English literature from 1920 to the present produced only a handful of articles for a total of 185 reported cases. All had bone formed within vertical incisions, usually within 1 year of surgery, and 89% were males. Knowledge of this phenomenon and the variable size at presentation is useful to both the autopsy pathologist and the anthropologist in generating a diagnosis for abnormal calcifications.     

Children’s Susceptibility to Misidentifying a Familiar Bystander From a Lineup: When Younger is Better

Children from 5 to 12 years of age (N=779) were shown a videotape where a preschool teacher has money stolen from her wallet. Children were shown a lineup, and for children in the bystander condition, the lineup contained a familiar bystander without the thief. Children in the control condition viewed the same lineup but they had not seen the bystander in the videotape. Among the 11–12-year olds, participants in the bystander condition were significantly more likely than control participants to misidentify the familiar bystander. This effect was not found in children from 5 to 10 years of age. When children in the control condition were shown a lineup that contained the thief without the bystander, the 11–12-year olds were significantly more likely than the younger children to correctly identify the thief. These findings demonstrate that age can both increase and decrease the accuracy of children’s lineup identification accuracy depending on the task at hand and the content of a lineup.     

A study of male veterans' beliefs toward domestic violence in a batterers intervention program

Domestic violence in intimate relationships is a ubiquitous social problem. This study addresses a gap in the research literature on batterers intervention programs with heterosexual male batterers by evaluating whether or not self-reported attitudes about partner abuse and sexist beliefs could be modified over time as a result of participation in a Batterers Intervention Program (BIP). Using the Inventory of Beliefs about Partner Abuse (IBAPA) to measure attitudes toward domestic violence and the Ambivalent Sexism Inventory (ASI) to measure sexist beliefs, results of the study provide empirical support for the notion that participation in BIPs affects the self-reported beliefs about their rights to physically and emotionally abuse their partner. These self-reported scores were adjusted for response bias by the long version of the Marlowe-Crowne Social Desirability Scale (MCD). Response bias and how it is treated in self-report measures with batterers is also discussed.     

Cross-validation of the risk matrix 2000 sexual and violent scales

The predictive accuracy of the newly developed actuarial risk measures Risk Matrix 2000 Sexual/Violence (RMS, RMV) were cross validated and compared with two risk assessment measures (SVR-20 and Static-99) in a sample of sexual (n= 85) and nonsex violent (n= 46) offenders. The sexual offense reconviction rate for the sex offender group was 18% at 10 years follow-up, compared with 2% for the violent offenders. Survival analyses revealed the violent offenders were reconvicted at twice the rate compared to sexual offenders. The RMV significantly predicted violent recidivism in the sex and combined sex/violent offender groups. Although the RMS obtained marginal accuracy in predicting sexual reconviction in the sex offender group, none of the scales significantly predicted sexual reconviction. An item analysis revealed four factors not included in the risk scales that were significantly correlated with sexual and violent reconviction. Combining these factors with Static-99, RMV, and RMS increased the accuracy in predicting sexual reconviction.     

Black soldier fly (Diptera: Stratiomyidae) colonization of pig carrion in south Georgia

The black soldier fly, Hermetia illucens (L.), is thought to colonize corpses 20-30 days postmortem. However, recent observations indicate this might not be true for all cases. Therefore, we conducted a study examining colonization by the black soldier fly and other Diptera on pig carrion in a plowed field in southern Georgia from 20 September through 21 February. Our data indicate black soldier flies could colonize a corpse within the first week after death. Knowing this information could prevent a serious mistake in estimating the time at which a corpse is colonized by this species. This study also represents the first record of Chrysomya rufifacies in Georgia.     

Cor triatriatum sinistrum: a rare congenital cardiac anomaly presenting in an adult with chronic atrial fibrillation

Cor triatriatum is a rare congenital cardiac anomaly in which the left atrium is divided into proximal (dorsal or upper) and distal (ventral or lower) chambers by a fibromuscular septum. The upper chamber receives the pulmonary veins and the lower chamber contains the atrial appendage and the mitral valve. The 2 chambers communicate through a defect in the membrane. Cor triatriatum is often associated with other congenital cardiac anomalies. Most frequently, the upper chamber communicates with the right atrium through a patent foramen ovale or atrial septal defect, and the clinical symptoms simulate anomalous pulmonary venous return. Less commonly, the foramen ovale communicates with the distal chamber and the clinical features mimic mitral stenosis. When cor triatriatum is the only abnormality, the clinical findings are also similar to mitral stenosis with development of pulmonary hypertension and subsequent right ventricular hypertrophy and atrial enlargement. The diagnosis is usually made in infancy or childhood, and the lack of treatment results in death in 75% of patients.We report the case of a woman who presented much later in life. The patient was a 57-year-old female with a clinical history of chronic atrial fibrillation who presented to the emergency department because of a "funny sensation" in her chest, though she denied chest pain, nausea, vomiting, or diaphoresis. EKG revealed atrial fibrillation with a rapid ventricular response and a tachycardic rate of 157. She had a therapeutic level of digoxin, and cardiac enzymes were normal. The patient was admitted and placed on Cardizem drip. Serial EKGs remained normal and heart rate control was achieved. On hospital day 2, the patient became dyspneic and cyanotic. She went into cardiac arrest and died.Autopsy revealed cardiomegaly (610 g) with 4-chamber dilatation. A septum divided the left atrium into 2 chambers. The defect in the dividing membrane measured 1 cm in diameter. No other congenital defects were noted. The large size of the defect in the membrane likely accounted for the late onset of symptoms that allowed this patient to survive into adulthood without previous diagnosis or surgical intervention (which is usually required in childhood).     

Peer Victimization,Social Support,and Psychosocial Adjustment of Sexual Minority Adolescents

The present study examined the link between sexual orientation and adjustment in a community sample of 97 sexual minority (gay male, lesbian, bisexual, and questioning) high school students, taking into account their experiences of peer victimization and social support within peer and family contexts. Adolescents were identified in a large-scale survey study conducted at 5 high schools. They were matched to a comparison sample of their heterosexual peers. Sexual minority adolescents reported more externalizing behaviors and depression symptoms than heterosexual youth. Compared to their heterosexual peers, sexual minority youth reported more sexual harassment, more bullying, less closeness with their mothers, and less companionship with their best friends. There were no significant differences between gay male, lesbian, bisexual, and questioning adolescents. Overall, both victimization and social support mediated the link between sexual orientation and psychosocial symptoms. Among sexual minority youth, the link between social support and externalizing was mediated by experiences of peer victimization. These findings highlight the contextual risk and protective factors associated with non-heterosexual sexual orientation in accounting for the emotional and behavioral problems in this population.

Political efficacy and trust: A report on the NES pilot study items

Political efficacy and trust—among the most frequently used survey measures of general political attitudes—are often maligned for their lack of reliability and validity. This paper reports results from the National Election Studies 1987 pilot study, which included more than thirty-five efficacy and trust items. Five attitudinal dimensions were hypothesized; four emerged clearly. One scale, internal efficacy, is especially robust; a four- to six-item scale represents a considerable improvement on existing NES measures. External efficacy is distinguished from political trust, at least when the former is measured in terms of the fairness of political procedures and outcomes rather than in terms of elite responsiveness to popular demands. Though less decisive, there also is support for dividing trust into incumbent- and regime-based components. The failure to find a similar incumbent- and regime-based distinction for external efficacy is in accord with theoretical perspectives.Revised version of a paper presented at the 1988 Annual Meeting of the Midwest Political Science Association.     

Sentencer and offender factors as sources of discrimination in magistrates' penalties for drinking drivers

This study examined the contributions of sentencer and case (legal and extralegal) factors to magistrates' sentences for 678 drink-drivers at 2 courts. Qualitative codings of magistrates' sentencing orientations were incorporated with case factors in a multivariate statistical model of differences in fines and disqualifications. Discriminations in penalties were related to offenders' legally relevant prior offenses and blood alcohol concentrations, and extralegal variables of offender age, gender and employment status. Men were treated more harshly than women, and young offenders more harshly than all other offenders except those over 56 years. Unemployed offenders were fined less, but disqualified for longer than offenders in the workforce. Magistrates' orientations and court interacted with offense categories to produce further differences related to blood alcohol concentration and recidivism. Sentencers responded to offender characteristics but also relied on their own mental images of stereotypic drink-drivers and their individualized sentencing orientations to exercise their discretionary powers. Results are discussed in relation to issues of warranted or justifiable discriminations and the just distribution of penalties.
