  1. Estimation of stress in child neglect from thymic involution.

    Article - En anglais

    It is difficult to evaluate the extent of stress in cases of suspected child abuse/neglect in a medico-legal autopsy.

    We have previously reported that stress due to abuse/neglect was found to have led to thymic involution.

    To elucidate the influence upon thymocytes differentiation, we compared the proportion of the thymocyte subpopulation in the thymus of a neglected child with one in an age-matched control obtained from cardiac surgery.

    We found that the relative number of CD4+CD8+double positive (DP) thymocytes decreased in the neglected child.

    It was presumed that the selective decrease in the number of the immature DP thymocytes with CD3-to low bcl-2low caused the thymic involution in the neglected child.

    It was suggested that an alteration in the proportion of thymocytes subpopulation might be used as an index of stress in cases of child abuse/neglect.
