70. CSF opening pressure measurement

    1. Normal range: 6 – 25 cm H2O. (T/F?)
    2. Bacterial meningitis: elevated. (T/F?)
    3. Viral meningitis: normal or elevated. (T/F?)
    4. Subarachnoidal hemorrhage : normal. (T/F?)
    5. Multiple sclerosis: elevated. (T/F?)
    6. Dehydration: decreased. (T/F?)

8. CSF in MS:

  1. Opening pressure:  elevated. (T/F?)
  2. Cell count: increased (5–50 lymphocytes/mm 3 ) in two-thirds of patients during an acute attack. (T/F?)
  3. Protein: can be mildly elevated, up to 100 mg/dl. (T/F?)
  4. Oligoclonal IgG bands:  present in more then 90% patients. (T/F?)
  5. IgG index : elevated in about 90% of patients with clinically definite MS. (T/F?)
  6. Oligoclonal IgG bands are specific for this disease. (T/F?)

  1. Multiple sclerosis does not cause elevated cerebrospinal fluid (CSF) opening pressure.
  1. Oligoclonal IGg bands can be shown in cerebrospinal fluid of the majority of MS patients, but they are not specific for multiple sclerosis.
