Maltreatment of the elderly is a common problem that affects more than 3% of the elderly. We report on two cases of fatal
neglect. Risk factors of victims and caregivers were analysed in the context of the social history. In both cases, the victims
had a dominant personality and the abusers (the sons) had been strictly controlled and formed by the parent. The victims showed
typical risk factors such as living together with the abuser, isolation, dependence on care, income and money administration.
Initially, the victims declined help from outside and self-neglect occurred. The unemployed perpetrators lived in social isolation
and depended financially and mentally on the victims. In both cases no mental illness was present but there was a decrease
of social competence. Legal medicine is predominantly involved in fatal cases in connection with external post-mortem examinations
and autopsies. Also in the living, the medico-legal expert can assist in the identification of findings in elderly persons
in cases of suspected abuse.

A series of hand and wrist radiographs was assessed manually by two individuals and by a fully automated computer system for determining bone age. Assessments were repeated after 1 month to determine variability between and within the methods of bone age assessment. There was slight intra-observer variation, but complete reproducibility when assessments were made by computer. The variation between the human assessors was less than that between human and computer assessments. The difference between overall maturity scores made by the human observer and the computer system was, however, acceptably small, and the majority of assessments were the same. It is concluded this computer system for assessing bone age in normal children is reliable and accurate, but that it needs to be validated against a much larger set of radiographs. 相似文献
