Between 1998 and 2007, 42 patients admitted to Choray hospital, Ho Chi Minh City, and to two hospitals in adjacent regions in southern Viet Nam brought the Malayan kraits (Bungarus candidus) that had been responsible for biting them. Half of the patients had been bitten while they were asleep. Fang marks and numbness were the only local features of the bites. ⋯ There were no fatalities. Hyponatraemia has been reported previously in victims of Chinese kraits (Bungarus multicinctus) in northern Viet Nam and rhabdomyolysis in patients envenomed by B. niger in Bangladesh. These features of envenoming pose new problems for the management of krait bite cases in South east Asia and should stimulate a search for the causative venom toxins.

We retrospectively analyzed 297 proven cases of Philodryas patagoniensis bites admitted to Hospital Vital Brazil (HVB), Butantan Institute, São Paulo, Brazil, between 1959 and 2008. Only cases in which the causative animal was brought and identified were included. Part of the snakes brought by the patients was still preserved in the collection maintained by the Laboratory of Herpetology. ⋯ Eight patients (2.7%) were mistreated with Bothrops antivenom before their admission to HVB. No sequels or relevant complications were observed in patients, and the prognostic was benign. Therefore, although P. patagoniensis accidents can cause mild local symptomatology, it is very important that health professionals know how to make the correct diagnosis to avoid unnecessary use of antivenom.
