    Notes: Abstract The effect of methylphenidate preceded by a moderate dose of haloperidol on reaction times over the duration of a continuous performance test (CPT) was investigated in ten male children, with a DSM-III diagnosis of attention deficit disorder with hyperactivity disorder (ADDH). Using a within-subject double-blind design, the effects of methylphenidate preceded by haloperidol on reaction time during the first and second blocks of CPT test were compared. Methylphenidate maintained a significantly improved reaction time in the second block of the CPT test. When methylphenidate, preceded by placebo, was preceded by haloperidol this effect was not observed, suggesting opposing effects on attentional systems by methylphenidate versus haloperidol. The study is the first to examine the “blocking” effect of haloperidol over the course of a CPT. The results suggest that dopamine systems are involved in the maintenance of the CPT response, and support an “incentive motivation” theory of sustained attention.

    Notes: Abstract The authors report on the contribution of odontological identification of the flight ALIT 5148 air disaster victims, which occurred on 20th January 1992. The identification procedure was difficult due to large numbers of bodies and mutilations and required the involvement of multidisciplinary teams composed of odontologists, forensic pathologists, radiologists and biologists. The authors set up a simple, discriminant classification which was easy to handle by a multidisciplinary team. Four groups were defined according to the matching characteristics between ante and post mortem data. Perfect matching characteristics between ante and post mortem data were achieved in only 44 cases (Group A). Partial matching characteristics between ante and post mortem data were achieved in 12 cases (Group B). In 29 cases, the insufficiency or absence of odontological data (Group C and D) did not enable the victim to be identified. The results of the investigations showed that the dental examination alone enabled 17 victims to be identified and by including a morphological examination the figure reached 33. By the end of the investigations, 85 of the 87 victims were positively identified. Odontological identification is an essential, accurate and rapid method with allows a body to be identified from its dental characteristics. This anthropometrical method of identification is included with the descriptive and the biological methods. The authors present their experience in performing a formal identification of 44 victims in less than 15 days.
