BACKGROUND : Syphilis serology is analysed in all patients admitted as in-patients to the Department of Neurology in Tromsø. In this study we examined the utility of performing routine laboratory testing for syphilis in neurological patients.
MATERIAL AND METHODS : We registered all in-patients in the Department of Neurology with a confirmed diagnosis of syphilis during a ten-year period (1990-1999). Additionally, we calculated the cost of performing laboratory tests of all hospitalised patients in this period.
RESULTS : From a total of 8,637 patients, we identified five patients with syphilis, one of them with neurosyphilis. This patient had impaired cognitive functions at the time of admittance and a broad spectrum of neurological deficits suggesting a serious neurological disease. A positive syphilis serology confirmed the diagnosis and treatment was initiated. The mean cost for Treponema pallidum serological screening in neurological patients during 10 years was calculated to be about NOK 17,000 per year.
INTERPRETATION : Tertiary syphilis is a serious disease with symptoms often mimicking other diseases. Although the laboratory tests for syphilis have been performed in every in-patient admitted to the neurological ward, a speedier diagnosis of neurosyphilis could not be detected in any patient in a ten-year hospital material. Routine serological examination for syphilis in neurological patients is therefore not recommended in this geographical area.
