PROBLEM: Question: Does diabetes influence oral oncogenesis through fibroblast growth factor receptors?
Answer: It seems that diabetes does not affect the FGFR-2 and FGFR-3 pattern of expression throughout the various stages of oral oncogenesis.

SOLUTION: no

PROBLEM: Question: Does 18F-FDG-PET/CT better localize active spinal infection than MRI for successful minimally invasive surgery?
Answer: FDG-PET/CT demonstrated limited areas of abnormality allowing accurate delineation, and is thus useful to narrow the surgical fields. Since overall diagnostic accuracy of FDG-PET/CT was superior to that of MRI, FDG-PET/CT is a useful technique to narrow the surgical field for successful less invasive surgery.

SOLUTION: yes

PROBLEM: Question: Is autologous blood donation in total knee arthroplasties necessary?
