White-tailed spider bites--arachnophobic fallout?
OBJECTIVE
To investigate if public concern regarding the toxic effects of the bites from white-tailed spiders, Lampona cylindrata and L. murina, is reflected in the case histories of patients admitted to Christchurch Hospital with a diagnosis of spider bite.


METHODS
The case histories of patients admitted to Christchurch Hospital with a diagnosis of 'contact with venomous spiders' were examined for evidence that the patients developed necrotising arachnidism.


RESULTS
Ten patients were admitted to Christchurch Hospital between January 2001 and January 2003 with a diagnosis of 'contact with venomous spiders'. We found no evidence that patients developed necrotising arachnidism. No patients admitted to Christchurch Hospital required re-admission to treat sequelae of the putative spider bite. Support for a spider bite as the causative agent was not robust and alternative agents could have been the cause.


CONCLUSIONS
The public's fear of bites from white-tailed spiders is likely misplaced and, if the spider was not caught in the act of biting the patient, alternative diagnoses should be considered before assuming a white-tailed spider was responsible for the patient's symptoms.
