[Routine screening for syphilis in neurology is not useful].
In a retrospective study the results of the screening for syphilis in one of the neurological wards of the Academic Medical Centre in Amsterdam were analysed. The Venereal Disease Research Laboratory test (VDRL) and the Treponema Pallidum Haemagglutination Assay (TPHA) in serum were used for screening. The data for analysis were obtained via the hospital computer data base and via the medical files of the department of neurology. During the 5-year study period (1986-1990) 2378 adult patients were admitted and 1247 (52.4%) of them were screened. In seven (0.56%) patients both tests were positive. Three of them had been treated for syphilis in the past and showed no symptoms of active syphilis. Four (0.32%) patients suffered from active neurosyphilis. In three of these four patients syphilis was suspected on admission and confirmed by the tests. In one patient the diagnosis of syphilis was not considered. The positive test results became available shortly before she died of pneumonia and were without consequences. None of the 32 (2.6%) patients with a positive TPHA and a negative VDRL was diagnosed as having (neuro-)syphilis. Two (0.16%) patients had a false-positive VDRL. We conclude that routine serological examination for syphilis of every patient admitted to a neurological ward is not useful. We advise a limited screening of patients who belong to a group with high risk for syphilis and patients with symptoms and signs that can be caused by syphilis, such as dementia or ischaemic strokes at a relatively young age.
