Abstract
The identification of hypothermia as the cause of death remains challenging in forensic pathology because of unspecific radiological, morphological, and biochemical results. Hyperemia, edema, and petechial hemorrhages within the cerebral parenchyma were described in cases of death by hypothermia. On the other hand, the effect of low temperatures in the brain has been speculated to cause local injuries on a cellular level with potential occurrences of necrosis and inflammation. In the study herein described, endocan, alkaline phosphatase, neuron-specific enolase, S100 protein subunit B, glial fibrillary acidic protein, and C-reactive protein were measured in postmortem serum from femoral blood and cerebrospinal fluid in a series of hypothermia fatalities and control cases. The combination of data collected failed to identify a specific biochemical profile for death by hypothermia in postmortem serum and/or the cerebrospinal fluid, thus suggesting that an alternative panel of brain damage biomarkers indicative of diffuse hypoxic brain injury needs to be defined in hypothermia fatalities.
