Aquatic dermatoses.

Despite the fascination of the aquatic world, it can be associated with some medical risks. Natural bodies of water, swimming pools and aquariums contain many living organisms. Some of these aquatic species may cause traumatic or toxic skin reactions after contact as well as life-threatening systemic reactions. Most frequently, the injuries include poisonous bites and stings by coelenter-ates, worms,stinging fish,mollusks and echinoderms or skin infections. A basic knowledge regarding the flora and fauna that populate the aquatic world can help to avoid contact with such organisms,or if it happens,to promptly initiate appropriate therapy.
