[The danger of neurosyphilis is again a reality].

The contemporary epidemiological position as regards syphilis, worldwide and in the Czech Republic, is deteriorating in a dangerous way. New cases are not adequately detected, their treatment is frequently implemented by non-professionals and the symptoms of the 1st and 2nd stage remain unnoticed and may be even lacking. In the near future we must foresee an increasing incidence of late complications of syphilis. The authors present four catamnestically followed up cases of progressive paralysis which were detected during the past five years at the Psychiatric Clinic of ther First Medical Faculty, Charles University, Prague. The observation confirms the old view that patients who contracted neurosyphilis must remain throughout life on the records of VD clinics despite excellent remission of the clinical condition as in none of their patients complete normalization of the finding in the cerebrospinal fluid was found.
