Detection of ketosis in vitreous at autopsy after embalming

Ketosis occurs in ketoacidosis or malnourishment. When either is suspected in relation to a death, it may be important to analyze for ketosis at autopsy. We encountered a case where starvation was suspected in a deceased nursing home resident, where the body had been embalmed prior to autopsy. Gas chromatography (GC) was unable to separate acetone from formaldehyde, a component of embalming fluid. The Acetest is a simple test that can detect acetone and acetoacetate in body fluids. We validated the Acetest with GC on vitreous. The Acetest and GC were consistent except at very low levels of acetone or acetoacetate. The sensitivity of the Acetest for acetoacetate in vitreous was 10 mg/dL, consistent with early starvation. Significant interference from embalming fluid did not occur. The Acetest was negative in the described case. The Acetest is a simple and useful test for the detection of ketosis in embalmed autopsies.     

A controlled,problem-solving,group-based intervention with vulnerable incarcerated young offenders

Recent research has indicated that vulnerable incarcerated young offenders--such as those at risk of suicidal behaviour, those on formal protection due to their inability to assimilate into mainstream, and those who are bullied but remain in normal circulation--display impoverished problem-solving abilities. Furthermore, deficits in their problem-solving skills are significantly correlated with levels of anxiety, depression, and hopelessness. This study evaluated the effectiveness of a time-limited, group-based problem-solving training intervention compared with a no-treatment control for vulnerable, incarcerated young offenders. A total of 46 young offenders were equally allocated to intervention or control groups. Intervention participants experienced significant reductions in their levels of anxiety, depression, and hopelessness and improvement in their self-assessed social problem-solving abilities. Gains in aspects of self-assessed problem-solving ability and mental health for the intervention group continued to be evident at 3-month follow-up. Methodological concerns in this study and directions for future research are discussed.     

An unusual case of driving under the influence of enflurane

An unusual case of driving under the influence of the volatile anaesthetic enflurane is reported. A markedly affected anaesthetist was sniffing at an enflurane-moistened handkerchief before he crashed into a lorry at a red traffic light. In the blood sample enflurane (2.92 mg/l) as well as diclofenac (0.28 mg/l) and 4-aminophenazone (24.4 mg/l) were found. The way of driving and the accident and the deficiency symptoms could be explained by the central suppressing effects of enflurane. The physician was considered as impaired and not suitable to drive at the time of the incidence.     

The talus: sex assessment of prehistoric New Zealand Polynesian skeletal remains

Prehistoric Polynesian skeletal remains are frequently being recovered in New Zealand due to the increasing pace of urbanisation. Since such material must often be reinterred quickly, it is important that the sex of individuals be determined from the remains in a relatively short time. For this purpose, discriminant function analysis was utilised for sex determination of prehistoric adult New Zealand Polynesian tali (24 males and 27 females). Five measurements were taken and subjected to Statistical Package for the Social Sciences (SPSS) discriminant function analysis. For the discriminant functions derived, accuracy of sex determination ranged from 85.1 to 93.3%. Reduction in error over random assignment by sex ranged from 70 to 87%.     

The Influence of Future Certainty and Contextual Factors on Delinquent Behavior and School Adjustment Among African American Adolescents

This study examined the ability of future certainty—an individual's perception of future stability, operationalized as the likelihood of certain life outcomes–to explain variance in delinquency and school adjustment, while controlling for economic, neighborhood, and family factors, among a cross-sectional sample of 1422 male and 1562 female African American adolescents drawn from the National Longitudinal Study of Adolescent Health (Add Health). Three kinds of future certainty were examined: future life certainty (e.g., life expectancy), marriage certainty, and college certainty. In hierarchical multiple regression analyses, future certainty and family functioning were stronger predictors than economic and neighborhood variables: neighborhood disorganization and family socioeconomic status. Future life certainty and expectations of attending college were stronger predictors of delinquency among males than females. Marriage certainty was the weakest predictor of the three certainty variables.     

Interpersonal Sensitivity, Romantic Stress, and the Prediction of Depression: A Study of Inner-City, Minority Adolescent Girls

The role of interpersonal sensitivity in the relation between romantic stress and depression was examined in 55 adolescent girls from an inner-city high school. Depression, interpersonal sensitivity, and chronic and episodic romantic stress were measured at two time points, 6 months apart. Interpersonal sensitivity was found to moderate the longitudinal relation between romantic stress (both chronic and episodic) and depression. In contrast, interpersonal sensitivity did not potentiate depressive responses to non-romantic interpersonal stress, suggesting particular importance of stress in the romantic domain for adolescent girls. Results indicate that girls' sensitivities to romantic relationship stress should be specifically addressed in depression prevention and intervention programs.Received her PhD from the University of Southern California. Research interests include the influence of romantic relationship factors, such as romantic stress and dating violence, on the development of depression during adolescence.Received her PhD from the University of California, Los Angeles. Research interests include the interplay between adolescent depression, personality disorder symptoms, and interpersonal variables including adjustment in friendships and romantic relationships.Research interests include cognitive and interpersonal factors in adolescent depression.     

Pubertal Maturation and African American Children’s Internalizing and Externalizing Symptoms

The association of pubertal maturation with internalizing and externalizing symptoms was examined with a sample of 867 African-American 10 – 12-year-old children. Children reported their pubertal development status and timing using a self-report questionnaire, and symptoms were assessed through diagnostic interviews with the children and their primary caregivers. Pubertal status and timing were significantly associated with children's reports of the internalizing symptoms of social anxiety disorder, generalized anxiety disorder, and major depression and with the externalizing symptoms of oppositional defiant disorder, attention deficit disorder, and conduct disorder. Pubertal development also was associated with caregivers’ reports of children's externalizing symptoms. The pubertal transition was associated with internalizing and externalizing symptoms in both boys and girls.Xiaojia Ge is Professor at the University of California, Davis.
