[Q]: Question: Does bacteriuria in patients with a continent ileal reservoir for urinary diversion regularly require antibiotic treatment?
Answer: The present results indicate that asymptomatic bacteriuria in patients with a continent ileal reservoir for urinary diversion is generally of no clinical importance and should not be treated with antibiotics. This conclusion is based on the observations that the bacterial strains growing in the reservoir changed spontaneously indicating colonization rather than infection. Raised titres of antibodies against E. coli correlated weakly with bacterial growth. The observed elevations in antibody titres were usually just above the normal upper limit.
[A]: no

[Q]: Question: Does spinal instrumentation in patients with primary spinal infections lead to greater recurrent infection rates : an analysis of 118 cases?
Answer: Patients who received just decompression for spinal infection had similar reoperation and continued infection rates as patients who additionally underwent instrumentation, irrespective of infection location within the spine. These findings suggest that instrumentation of the infected spine may be a safe treatment modality and should be considered when the spinal integrity is compromised.
[A]:
no
