Comamonas testosteroni meningitis in a homeless man

We report a case of meningitis caused by Comamonas testosteroni in a 54-year-old, alcoholic, homeless man. He, as a pedestrian, was struck by a car and suffered multiple fractures of the facial bones including the left frontal sinus. Over the course of 2-week hospitalization, he was clinically diagnosed with multiple cerebral and cerebellar infarcts resulting in altered mental status. He was pronounced dead 15 days after the injury. At the time of autopsy, diffuse purulent meningitis was found on gross examination. A swab culture of the brain surface was positive for C. Testosteroni, a saprophytic organism commonly found in soil and water. This is the first reported case of fatal meningitis caused by this micro-organism.     

Sex determination from the radius and ulna in a modern South African sample

With a large number of unidentified skeletal remains found in South Africa, the development of population specific osteometric standards is imperative. Forensic anthropologists need to have access to a variety of techniques to establish accurate demographic profiles from complete, fragmentary and/or commingled remains. No research has been done on the forearm of African samples, even though these bones have been shown to exhibit sexual dimorphism. The purpose of this paper is to develop discriminant function formulae to determine sex from the radius and ulna in a South African population. The sample consisted of 200 male and 200 female skeletons from the Pretoria Bone (University of Pretoria) and Raymond A. Dart (Witwatersrand University) collections. Sixteen standard anthropometric measurements were taken from the radius (9) and ulna (7) and subjected to stepwise and direct discriminant function analysis. Distal breadth, minimum mid-shaft diameter and maximum head diameter were the best discriminators of sex for the radius, while minimum mid-shaft diameter and olecranon breadth were selected for the ulna. Classification accuracy for the forearm ranged from 76 to 86%. The radius and ulna can be considered moderate discriminators for determining sex in a South African group. However, it is advised that these formulae are used in conjunction with additional methods to determine sex.     

Anger disturbances among perpetrators of intimate partner violence: clinical characteristics and outcomes of court-mandated treatment

In the present study, the authors clustered a pretreatment sample of 190 perpetrators of intimate partner violence (IPV) mandated to attend group counseling based on State-Trait Anger Expression Inventory scores and examined whether these profiles were associated with differential outcomes 1 year postadjudication. Cluster analysis revealed 3 groups: (a) high anger-expressive (HA-E, n = 56), (b) moderate anger-inexpressive (MA-IE; n = 13), and (c) low anger (LA; n = 118). HA-E men perpetrated more IPV, reported experiencing and witnessing more abuse during childhood, scored higher on psychopathology measures, and reported more substance problems. HA-E and MA-IE males had higher program attrition and rearrest rates; MA-IE males were more likely to be arrested for assault-related offenses. Thus, although the majority of partner-abusive men do not present with anger-related disturbances, the presence of anger problems may be a marker for an array of traits that may complicate the treatment process.     

Aggression control therapy for violent forensic psychiatric patients: method and clinical practice

Aggression control therapy is based on Goldstein, Gibbs, and Glick's aggression replacement training and was developed for violent forensic psychiatric in- and outpatients (adolescents and adults) with a (oppositional-defiant) conduct disorder or an antisocial personality disorder. First, the conditions for promoting "treatment integrity" are examined. Then, target groups, framework, and procedure are described in detail, followed by the most important clinical findings during the period 2002 to 2006. Finally, new programme developments are mentioned, with aggression control therapy as a starting point.

Evaluation of principal components analysis with high-performance liquid chromatography and photodiode array detection for the forensic differentiation of ballpoint pen inks.

Inks from seven black and eight blue ballpoint pens were separated by a high-performance liquid chromatography (HPLC) method utilizing a photodiode array detection (PDA). A classifier flowchart was designed for the chromatographic data based on the presence or absence of certain peaks at different wavelengths to qualitatively discriminate between the inks. The same data were quantitatively classified by principal components analysis (PCA) to estimate the separation between a pair of classes of ink samples. It was found that the black ballpoint pen inks were discriminated satisfactorily utilizing two-dimensional data of the peak areas and retention times at the optimum wavelengths. The blue pens were discriminated by analyzing the chromatographic data at four different wavelengths simultaneously with a cross-validated PCA. The results of this study indicated that HPLC-PDA coupled with chemometrics could make a powerful discriminating tool for the forensic chemist, especially when analyzing extensive and/or complex data.

Relationships between Social Information Processing and Aggression among Adolescent Girls with and without ADHD

This study investigated the relationship between social information processing (SIP) and both relational and overt, physical aggression in a longitudinally-followed sample of 228 adolescent girls (ages 11–18; 140 with ADHD and 88 comparison girls). During childhood, girls participated in naturalistic summer camps where peer rejection, overt physical aggression, and relational aggression were assessed via multiple informants and methods. Approximately 4.5 years later, these girls participated in follow-up assessments during which they completed a commonly-used vignette procedure to assess SIP; overt and relational aggression were again assessed through multiple informants. Correlations between (a) overt and relational aggression and (b) maladaptive SIP were modest in this female adolescent sample. However, relationships between aggression and SIP were stronger for the comparison girls than for the girls with ADHD. The relevance of SIP models for adolescent girls and clinical implications of findings are discussed.
