1 "When tumor cells gain access to the cerebral spinal fluid and the subarachnoid space, current therapy is largely ineffective, " said Dr. Raffel.

2 Health workers routinely collect spinal fluid when examining someone who is suspected of having meningitis.

3 The team evaluated spinal fluid taken from 410 patients who were part of a large Alzheimer's study.

4 It's also present in spinal fluid and, in very small quantities, in the blood.

5 Cerebral spinal fluid (CSF) samples have been received for testing at the National Institute of Communicable Diseases (NICD), Delhi, 35 samples have tested positive so far for serogroup A.

6 And taking spinal fluid requires a lumbar puncture, an often painful procedure many people would rather avoid, O'Bryant said in a telephone interview.

7 Among 7 specimens of cerebral spinal fluid found positive for Neisseria meningitidis by culture, 4 belong to serogroup W135.

8 One specimen of cerebral spinal fluid has been found positive for Neisseria meningitidis serogroup A by latex test.

9 Other teams have shown spinal fluid tests, which require a spinal tap, can detect early changes that signal the onset of Alzheimer's, which affects at least 26 million people globally.

10 Spinal fluid from tube # 4 contained 113 WBC, 40 RBC, protein 97 and glucose 80.

11 Other companies are working on tests for substances in blood and spinal fluid.

12 When treatment is needed, a spinal tap (lumbar puncture) is done. Then spinal fluid is removed and chemotherapy is injected into the spinal canal.

13 Following laboratory confirmation of Neisseria meningitidis serogroup W135 in two specimens of cerebral spinal fluid, the ICG has provided 102 375 doses of trivalent ACW vaccine.

14 If treatment is started prior to the lumbar puncture it may be difficult to grow the bacteria from the spinal fluid and confirm the diagnosis.

15 Initial diagnosis of meningococcal meningitis can be made by clinical examination followed by a lumbar puncture showing a purulent spinal fluid.

16 Drugs such as methotrexate, cytarabine and hydrocortisone are injected into the spinal fluid to prevent CNS leukemia.

17 This avoids injury to the latter plate and the resulting cerebral spinal fluid rhinorrhea.

18 Another study, also published in Science, links the finding to humans, showing that amyloid beta levels in the spinal fluid of volunteers increased when they were awake and fell during sleep.

19 How were you to know? Same thing with the spinal fluid?

20 The bacteria can sometimes be seen in microscopic examinations of the spinal fluid.

21 Your doctor will have to decide if the cause is bacterial, viral or fungal and will have to analyze your spinal fluid so a spinal tap will be ordered.

22 These parts of the body are treated by injection into the spinal fluid.

23 The diagnosis is supported or confirmed by growing the bacteria from specimens of spinal fluid or blood, by agglutination tests or by polymerase chain reaction (PCR).

24 A spinal tap (also called a lumbar puncture) is used to check the spinal fluid for ALL-cells.

25 It could signal normal pressure hydrocephalus, in which pockets in the brain swell with too much spinal fluid.
