Jager H, Schimrigk K, Haas A.: factor of 10 reduction of PLPS confirmed in random double-blind study.

Ohman, Ernerudh, Forsberg, Roberg and Vrethem: In the determination of CSF IgM by Lumbar Puncture, the inner wall is shown to be contaminated by the action of a Quincke needle penetrating the tissue. Ohman et al determine that use of a Sprotte needle – whose conical tip displaces the tissue pressure from the lateral opening – eliminates such contamination, thereby increasing the meaningfulness of CPS diagnostics for MS and infections.
