A preliminary survey of Hong Kong snake shops and the potential snake bite risks for the healthcare system.

Consumption of snakes is a traditional part of Chinese life. Snake shops, which provide both the food products and live snakes to the public, are believed by the medical community to stock only local species. The medical risk posed by these live snakes is therefore regarded as manageable as they are indigenous and thus effective anti-snake venom (ASV) is believed to be available.

Two cases of methemoglobinemia following zopiclone ingestion.

Introduction: Most cases of methemoglobinemia result from exposure to certain medications and chemicals such as nitrates, nitrites, aniline, dapsone, phenazopyridine, benzocaine, and chlorates which oxidize the iron from the ferrous state. Intoxication with zopiclone is expected to produce drowsiness, confusion and coma but not methemoglobinemia. We report two cases of zopiclone overdose with methemoglobinemia.
