The theory of cardiac lesions from blunt chest injury

The main theories of myocardial lesions associated with a blunt chest injury proposed starting from the XIXth century till the present time are considered based on the overview of the literature data. It is shown that the theory of selective mechanical activation of ATP-dependent K+ channels is most promising for further investigations into the mechanisms of myocardial dysfunction resulting from blunt chest injuries. The authors emphasize the absence of the universally accepted theory explaining the mechanism behind traumatic cardiac troubles and its fatal outcome despite numerous studies of cardiac lesions in patients with a blunt chest injury. It dictates the necessity of further research, both clinical and experimental, for a deeper insight into the problem.     

The propriety of establishing the fact of neonatality based on the examination of the child's corpse

It is shown based on the historical and legal analysis that the designation of the child's status as a newborn infant throughout the period of its neonatal life till violent death "at or immediately after births" is the exclusive prerogative of the law-enforcement authorities. An original approach has been developed and recommended for the introduction into the expert practice. According to this proposal facts and arguments in the "Expert conclusions" should be formulated so as to avoid mentioning the child as newborn and to indicate only the duration of its extrauterine life. Such an approach leaves it to the law-enforcement authorities to decide in each concrete case whether the child should be designated as a newborn infant or not.
