By | January 2, 2022


  • Abnormal sensations (paresthesia), often called lightning pains
  • Problems walking such as with the legs far apart.
  • Loss of coordination and reflexes.
  • Joint damage, especially of the knees.
  • Muscle weakness.
  • Vision changes.
  • Bladder control problems.
  • Sexual function problems.

What is Tabe dorsalis?

Definition. Tabes dorsalis is a slow degeneration of the nerve cells and nerve fibers that carry sensory information to the brain. The degenerating nerves are in the dorsal columns of the spinal cord (the portion closest to the back of the body) and carry information that help maintain a person’s sense of position.

Why is it called tabes dorsalis?

Symptoms result from degeneration of the dorsal roots of the spinal cord, giving it its name, which means dorsal wasting. The first manifestation is usually lightning pain, transient, stabbing pains affecting the legs; this is followed by loss of tendon reflexes and by progressive loss of muscular coordination ( …

What is Tabetic delirium?

tabes dorsalis a slowly progressive nervous disorder, from degeneration of the dorsal columns of the spinal cord and sensory nerve trunks, resulting in disturbances of sensation and interference with reflexes and consequently with movements; called also locomotor ataxia.

How tabes dorsalis relates to the dorsal root?

Recent studies demonstrated the role of CXCL13 in the diagnosis of asymptomatic patients so as to differentiate between symptomatic patients with asymptomatic HIV-infected patients. The value of CXCL 13 increases in HIV-infected patients accompanied by tabes dorsalis.

Which tracts are affected in tabes dorsalis?

Tabes dorsalis is a late consequence of neurosyphilis, characterized by the slow degeneration (specifically, demyelination) of the neural tracts primarily in the dorsal root ganglia of the spinal cord (nerve root).

Is tabes dorsalis bilateral?

In 90% of patients, the pupils are bilaterally small and fail to constrict further in response to light, but they do respond normally to accommodation (i.e., Argyll Robertson pupils). The onset of tabes dorsalis is usually first noticed 20 to 30 years after the initial infection.

What are symptoms of neurosyphilis?

Depending on the form of neurosyphilis, symptoms may include any of the following:

  • Abnormal walk (gait), or unable to walk.
  • Numbness in the toes, feet, or legs.
  • Problems with thinking, such as confusion or poor concentration.
  • Mental problems, such as depression or irritability.
  • Headache, seizures, or stiff neck.

What is RPR?

RPR (rapid plasma reagin) is a screening test for syphilis. It measures substances (proteins) called antibodies that are present in the blood of people who may have the disease.

Where is the lesion in tabes dorsalis?

Tabes dorsalis is a slowly progressive parenchymatous degenerative disease involving the posterior columns (ie, demyelination) and posterior roots (ie, inflammatory change with fibrosis) of the spinal cord.

What is a Gumma in syphilis?

A gumma is a soft, tumor-like growth of the tissues (granuloma) that occurs in people with syphilis.

What is sensory gait?

Due to the loss of sensation in the feet and legs in sensory ataxia, sufferers develop an unsteady, possibly stomping gait, with the foot striking the ground hard on each step, which is sometimes described as ‘walking on pillows’. It may also be associated with pain in the feet and legs.

What is Tabo paresis?

Tabo-paresis is a form of tertiary syphilis which contains features of both tabes dorsalis and general paralysis of the insane. Taboparesis is one of the causes of a mixed picture of upper and lower motor neurone signs in the legs leading to the presence of absent ankle jerks and extensor planter responses.

What is general paresis of the insane?

General paresis, also known as general paralysis of the insane (GPI) or paralytic dementia, is a severe neuropsychiatric disorder, classified as an organic mental disorder and caused by the chronic meningoencephalitis that leads to cerebral atrophy in late-stage syphilis.

What changes in the CSF would indicate neurosyphilis?

The diagnosis of neurosyphilis is based on a CSF WBC count of 20 cells/L or greater, and/or a reactive CSF VDRL, and/or a positive CSF intrathecal T pallidum antibody index. CSF abnormalities include elevated protein levels and pleocytosis, which are found in up to 70% of patients.

What is cerebellar gait?

The clinical features of cerebellar ataxic gait usually include a widened base, unsteadiness and irregularity of steps, and lateral veering. Locomotion in individuals with cerebellar ataxia is characterized by a significantly reduced step frequency with a prolonged stance and double limb support duration.

What does the dorsal column control?

The dorsal column, also known as the dorsal column medial lemniscus pathway, deals with the conscious appreciation of fine touch, 2-point discrimination, conscious proprioception, and vibration sensations from the body; sparing the head.

What is Argyll Robertson pupil?

The Argyll Robertson (AR) pupil has been defined as a pupil that is small and constricts poorly to direct light but briskly when a target within reading distance is viewed (light-near dissociation).

What is posterior cord syndrome?

Posterior cord syndrome is a rare type of incomplete spinal cord injury that affects the dorsal or posterior columns of the spinal cord, which are responsible for the perception of vibration, fine-touch and body positioning (i.e. proprioception).

What caused syphilis?

The cause of syphilis is a bacterium called Treponema pallidum. The most common way syphilis is spread is through contact with an infected person’s sore during sexual activity. The bacteria enter the body through minor cuts or abrasions in the skin or mucous membranes.

What is Gummatous ulcer?

gummatous ulcer lesion of the skin occurring in late syphilis.

What is cervical myelitis?

Cervical myelopathy results from compression of the spinal cord in the neck (cervical area of the spine). Symptoms of cervical myelopathy may include problems with fine motor skills, pain or stiffness in the neck, loss of balance, and trouble walking.

What is Tabetic stamping?

tabetic gait an ataxic gait in which the feet slap the ground; in daylight the patient can avoid some unsteadiness by watching his feet. three-point gait that in which both crutches and the affected leg are advanced together and then the normal leg is moved forward. See illustration at crutches.

What is tertiary syphilis?

Tertiary syphilis refers to gummas, cardiovascular syphilis, psychiatric manifestations (e.g., memory loss or personality changes), or late neurosyphilis.

What is the difference between syphilis and neurosyphilis?

It can occur in people with syphilis, especially if they are left untreated. Neurosyphilis is different from syphilis because it affects the nervous system, while syphilis is a sexually transmitted disease with different signs and symptoms.

What part of the brain is affected by neurosyphilis?

The middle cerebral artery is most often affected. Parenchymal syphilis occurs years to decades after initial infection. It presents with the constellation of symptoms known as tabes dorsalis, because of a degenerative process of the posterior columns of the spinal cord.

How do you diagnose neurosyphilis?

The diagnosis of neurosyphilis is based on a CSF WBC count of 20 cells/L or greater, and/or a reactive CSF VDRL, and/or a positive CSF intrathecal T pallidum antibody index. CSF abnormalities include elevated protein levels and pleocytosis, which are found in up to 70% of patients.

What does a reactive RPR indicate?

A reactive RPR test result is considered abnormal because antibodies were detected. This could either indicate a current syphilis infection, or the presence of a past infection that has been successfully treated.

What does syphilis RPR mean?

Definition. RPR (rapid plasma reagin) is a screening test for syphilis . It measures substances (proteins) called antibodies that are present in the blood of people who may have the disease.

What is positive RPR titer?

A positive titer with a VDRL or RPR indicates active syphilis and follow-up serologic testing is performed to monitor treatment response. With this new testing algorithm that uses the treponemal test first, some patients may test positive for a treponemal test but test negative with a nontreponemal test.
