Tabes dorsalis
Tabes dorsalis (pronounced: /ˈteɪbiːz dɔːrˈsælɪs/) is a late manifestation of untreated syphilis that affects the dorsal columns of the spinal cord and the peripheral nerves.
Etymology
The term "tabes dorsalis" is derived from the Latin "tabes" meaning "wasting" and "dorsalis" meaning "of the back". This refers to the characteristic wasting of the dorsal columns of the spinal cord in this condition.
Symptoms
The symptoms of tabes dorsalis include ataxia, loss of deep tendon reflexes, paresthesia, muscle weakness, and Argyll Robertson pupil, a condition where the pupils constrict when the patient focuses on a near object but do not react to direct light.
Diagnosis
Diagnosis of tabes dorsalis is typically made through a combination of clinical history, physical examination, and serologic testing for syphilis. A lumbar puncture may also be performed to examine the cerebrospinal fluid.
Treatment
Treatment for tabes dorsalis involves administration of penicillin, which can halt the progression of the disease, though it may not reverse the damage already done.
