question:
Question: Is repeated sputum microscopy essential for monitoring tuberculosis treatment response?
Answer: The yield of a second on-the-spot sputum specimen is negligible, provided that the first smear is from an overnight specimen. From the data available, it is evident that repeated follow-up smears are not essential for documenting treatment outcome.
answer:
no


question:
Question: Does classical swine fever virus induce oxidative stress in swine umbilical vein endothelial cells?
Answer: Our results indicated that CSFV infection induced oxidative stress in SUVECs. These findings provide novel information on the mechanism by which CSFV can alter intracellular events associated with the viral infection.
answer:
yes


question:
Question: Is contemporary revision penile prosthesis surgery associated with a high risk of implant colonization or infection : a single-surgeon series?
Answer: In our series, the infection risk associated with revision of malfunctioning devices was no greater than primary implant placement. Rerouting was associated with a higher infection risk, likely due to technical factors, and not implant colonization. Less than 10% of our revision implants were colonized, and this had no bearing on the development of a postoperative infection. S. epidermidis was not the most common organism implicated in device infections. Finally, our experience with an adjuvant, alcohol-based skin prep warrants further randomized prospective evaluation.
answer:

no
