Reconstruction of root morphology in skeletonized remains with postmortem dental loss.

A reversible technique is presented in which the root morphology of missing teeth in skeletonized human remains can be reconstructed for the purpose of radiographic comparison and postmortem identification. In this technique, which is based upon pilot studies with skeletonized mandibles of archival remains, the alveolar socket walls are sealed with a coat of cyanoacrylate cement and injected with a mixture of vinyl polysiloxane and barium sulfate. Radiographs are produced with the radiopaque mixture in place, which highlights the antemortem morphology of the roots. Subsequently, the impression material is removed, resulting in no gross alteration of the evidence. The radiographs made with this technique, as well as the impressions, can be stored for later use at a trial or pending the discovery of antemortem dental evidence.     

Drinking and driving in Singapore, 1987 to 1989.

Between 1987 and 1989 there were approximately 5,000 cases of fatal and injury-sustained road traffic accidents, of which 2.3-3.0% were alcohol related (blood alcohol levels greater than the legal limit of 80 mg% ethanol). The offenders of alcohol-related accidents are mostly Chinese (> 79%), male (> 98%), and more often 30-40 years old. The majority of the alcohol-related accidents (> 74%) took place between 8 P.M. and 4 A.M. in fine weather and light traffic. Rear-end, head-on, and side-on collisions comprised > 60% of all the alcohol-related accidents, and losing control of vehicles approximately 30%. Drunken driving cases for the same period that were not accidents showed a number of characteristics similar to those for accidents. In Singapore, motorcycle riders and pedestrians are more prone to road fatality than other road-user groups. International comparisons of road fatalities per 100,000 population gave Singapore one of the lowest accident rates (8.1-8.4) as compared with countries such as Australia, the United Kingdom, the United States, New Zealand, Canada, and Japan.     

Sudden death in a neonate as a result of herpes simplex infection

This paper describes a case of a neonate with disseminated herpes simplex born to a 14-year-old asymptomatic mother. The infant's physical examination was normal at birth, and subsequent abnormalities were so subtle that infection was not recognized during life. Postmortem cultures of liver and spleen grew herpes simplex virus, and immunofluorescent direct antibody typing revealed Type 2. A cervical culture of the mother obtained after the infant's death was negative.     

Assessing and predicting the competency of juvenile court volunteer probation officers

The volunteer movement in criminal justice settings is burgeoning. It has been estimated that by the end of 1982 there will be over one million volunteers working in criminal-justice-related functions. The volunteer role that appears to be increasing most rapidly is that of the one-to-one counseling relationship with delinquent and young adult offenders on formal or informal probation. While the demand for volunteer probation officers is increasing rapidly, few of our courts have attempted to develop and validate screening instruments capable of assessing and predicting the general competency of the volunteer. The need for such instruments has been emphasized recently by Judge Keith J. Leenhouts, Director of Volunteers in Probation, a division of the National Council on Crime and Delinquency. The present study attempts to assess the usefulness of one such potential screening device, the Critical Incident Response Test (CIRT) developed by Traitel (1972) and others at the Oakland County Juvenile Court in Pontiac, Michigan. It is hoped that this study will motivate other probation departments and court volunteer programs to develop and validate similar selection instruments.     

The evidential value of peptidase A as a semen typing system

Human erythrocyte peptidase A (Pep A) displays a genetic polymorphism in blacks. Its occurrence in human semen was examined for its possible use as a semen typing system. Studies by starch gel electrophoresis, in which the Pep A was located by an improved method, were carried out on semen, semen stains, and vaginal swabs taken at known times after intercourse. In addition, a large number of vaginal swabs, negative for semen, were taken from females throughout their menstrual cycles and examined for Pep A activity. The results indicated that Pep A typing could be carried out on semen and semen stains. However, it was possible to determine the Pep A type on vaginal swabs only when they had been taken within about 3 h after intercourse.
