PROBLEM: Question: Does metoclopramide influence the frequency of propofol-induced spontaneous movements?
Answer: Metoclopramide does not affect the frequency of propofol-induced movements, but propofol and fentanyl doses influence the frequency of movements during propofol induction.

SOLUTION: no

PROBLEM: Question: Does [ Histology accurately predict the clinical behaviour of bronchopulmonary carcinoids - results from an Icelandic population-based study ]?
Answer: BPCs usually behave as benign neoplasms, with excellent long-term survival after surgical removal. Metastases are more common in patients with atypical histology (40%), and their survival is worse. However patients with typical histology can metastasize (14.8%) and die from the disease. Therefore, histology (typical vs. atypical) can not be used with certainty to predict the clinical behaviour of these tumors.

SOLUTION: no

PROBLEM: Question: Does major surgery increase serum levels of vascular endothelial growth factor only temporarily?
Answer: Even major surgery is associated only with a slight and transient increase in S-VEGF levels, and, therefore, is unlikely to interfere markedly with the use of VEGF as a prognostic marker.

SOLUTION:
yes
