[Health damage after jellyfish stings].
BACKGROUND
Stinging jelly fish are found in most open waters and may vary in size from a few millimetres to many meters. Periodically they are found in large numbers and contact with people occurs frequently. Reactions may vary from mild skin rash to life-threatening symptoms.


METHODS
This article is based on the author's clinical experience and search of current literature on Medline and www.google.com using the following keywords; jellyfish sting, nematocyst, skin, allergy, health damage.


CONCLUSIONS
Contact with stinging jellyfish on the Norwegian coast lead to minor skin rashes that usually disappear within a few hours. Contact with species in tropical seawater or with jellyfish in general by children or allergic persons may result in serious systemic reactions and permanent skin lesions. It is important in such cases to rinse the affected area carefully with seawater or vinegar, which inactivates the toxins. Patients with systemic reactions must be observed or hospitalized. The skin rash may be covered with topical anaesthetics. Analgesics, antihistamines and steroids are options if vigorous local reactions occur. Infection and hypertrophic scarring is managed according to general guidelines. Hyperpigmentation may be removed with topical bleaching agents.
