Weight of adrenal glands may be increased in persons who commit suicide.

In a previous study, increased weight of the adrenal glands was found in a small group of persons who committed violent suicides. This finding was confirmed in our study, which comprised a group of 42 suicide cases and 37 control cases. Further analysis with special consideration toward a "relative adrenal weight" (weight/body surface) revealed that a relative combined adrenal weight >6 g/m2 may be a morphologic sign of a depressive disorder prior to death if no other disease with a known effect on the adrenals is present. These results are consistent with clinical computed tomographic findings of enlarged adrenals in depressed patients. In all suicide cases the police records were reviewed and a postmortem psychiatric diagnosis conducted to investigate whether a correlation between adrenal weight and the "severity" of depression or type of psychiatric disorder exists. In thirteen cases, psychiatric treatment prior to death was known, and a postmortem severity score of depressive disease was formed. No influence of this score or the postmortem diagnosis on the adrenal weight, however, could be detected. Also, the increase in weight of adrenal glands could not be explained by a suspected or proven preceding drug therapy or use. The effect on the pituitary-adrenal-axis by depressive disorders and changes in serotonin metabolism have been investigated repeatedly; mainly reported are increased levels of corticotropin-releasing hormone (CRH) and adrenocorticotropic hormone (ACTH) in the depressive interval, which may lead to a growth of the adrenal glands.

Morphological changes in adrenals from victims of suicide in relation to altered apoptosis.

Endocrine dysfunction may cause psychiatric symptoms and, vice versa, psychiatric diseases may lead to endocrine alterations. The adrenal as the end organ of both the hypothalamic-pituitary-adrenocortical and sympatho-adrenal axes is subject to the functional changes of the stress system. Thus, increased adrenal gland weight was observed previously in victims of violent suicide. This study was designed to analyze the morphological and morphodynamic changes of adrenals from suicide victims. We investigated 30 adrenals obtained from 15 suicide victims using immunohistochemistry and a computerized video system. In addition, apoptosis and cell proliferation were analyzed. We found a significant enlargement of the adrenal cortex to 158.8% (SD = 29.8%, p < 0.01) that was restricted to the two inner zones only (zona reticularis, 161.6 +/- 35.3%; zona fasciculata, 186.4 +/- 34.4%). This increase in adrenocortical size correlated with a decrease in the number of apoptotic cells within the zona fasciculata. In conclusion, these results clearly demonstrate chronic structural adrenal changes in suicide victims. The adrenal gland mirrors the functional changes of the stress system which leaves an imprint on the morphology of the gland.

[A new examination program for forensic assessment: performance of computers in medicine]. / Ein neues Untersuchungsobjekt für die rechtsmedizinische Begutachtung: Computerleistungen in der Medizin.

Computerizing of medicine is expected to increase very rapidly in the next few years. This will bear new questions for forensic judgement. We report a case and our expert opinion concerning the use of a very simple computer program at a private hospital to obtain comments on laboratory findings. Furthermore we discuss questions we consider to be of importance for forensic judgement in this field.
