[Haemorrhagic colitis after colonoscopy].

We report the case of a 43-year-old woman with an acute haemorrhagic colitis after colonoscopy with ambulatory anaesthesia. The diagnosis is likely to have been glutaraldehyde induced colitis (used for disinfection of the endoscope). The patient recovered spontaneously completely.

1H NMR spectroscopy and GC-MS analysis of alpha-chloralose. Application to two poisoning cases.

Alpha-chloralose, a compound widely used as a rodenticide and in the control of bird pests, is readily available. Two cases of intentional poisoning are reported. Both patients became comatose and presented hypersialorrhea and myoclonal crises in the legs.
