About syphilitic diseases of internal organs
The very fact that I have the high honor to speak here, in the oldest center of medical science, in Utrecht, in your highly respected Society for Syphilitic Diseases of Internal Organs, testifies to the great interest and significant urgency of the problem of visceral syphilis. Three chronic infections are the cause of a large number of lesions of internal organs - tuberculosis, malaria and syphilis - and of them syphilis really deserves special attention, since it is about it that the doctor most often forgets, and meanwhile, at the time of recognizing a syphilitic disease of internal organs, it often means not only save the patient, but also experience the greatest pleasure of medical creativity and the joy of fulfilling the high duty of a doctor.
