PROBLEM: Question: Is cerebral acetylcholinesterase activity decreased in MS patients with cognitive impairment?
Answer: In the patient group regional AChE activities had inverse correlations with Word learning and MMSE (Mini-Mental State Examination) scores. In the group of cognitively deteriorated MS patients no change in cerebral AChE activity, compared with controls, was observed, but within the patient group more pronounced cognitive symptoms were associated with higher cerebral AChE activity.

SOLUTION: no

PROBLEM: Question: Does the extent of lymphadenectomy for pTXNO prostate cancer affect prostate cancer outcome in the prostate specific antigen era?
Answer: The extent of lymphadenectomy does not appear to affect prostate cancer outcome in lymph node negative cases. This includes patients with high preoperative PSA, high pathological grade and extracapsular disease. These results suggest that under staging is not present in apparently node negative cases with limited lymphadenectomy and, even if present, its impact on outcome is likely to be negligible.

SOLUTION: no
