DIABETIC DEATH BED - POSTMORTEM DETERMINATION OF HYPOGLYCEMIA

The post-mortem biochemical determination of hypoglycaemia in the practice of forensic medicine is notoriously imprecise and attracts perennial criticisms, particularly from those who may be alien to the peculiarities of medical jurisprudence. There has been re-emphasis recently on the neuropathological pathoclisis ascribed to prolonged hypoglycaemia. Unfortunately the value perceived is limited by pathognomonic unreliability owing to agonal multifactorial influences and rapidly fatal nocturnal hypoglycaemia. The predicament is oppressive to a consideration of preponderant evidence and an unpopular diagnosis of perimortem hypoglycaemia, unless audacious, may be precluded simply because the proof is difficult. This is likely to contribute to diagnostic under-estimation of enigmatic diabetic deaths. A suspected case of lethal nocturnal hypoglycaemia in a young diabetic on 'animal' insulin is presented to restore some perspective to the clinico-pathological deference for an endangered post-mortem diagnosis of hypoglycaemia inferred from minimal evidence.
