PROBLEM: 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.

SOLUTION: no

PROBLEM: Question: Do an update on long-term outcome of curative hepatic resection for hepatocholangiocarcinoma?

SOLUTION: yes

PROBLEM: Question: Is mild hypercapnia after uncomplicated heart surgery associated with hemodynamic compromise?
Answer: The findings of this study suggest that unless there is a specific contraindication to mild hypercapnia, such as pulmonary hypertension or hemodynamic instability, concerns about mild respiratory acidosis should not prevent weaning of sedation and mechanical ventilation after uncomplicated heart surgery.

SOLUTION:
no
