Q: Question: Does vasopressin raise cardiac enzymes following cardiac surgery : a randomized double-blind clinical trial?
Answer: Vasopressin infusion has been used to treat catecholamine-unresponsive shock. In this study, intraoperative vasopressin was used safely as a possible first-line drug for treating hypotension; however, it did not increase the levels of cardiac enzymes after cardiac surgery.

A: no

Q: Question: Does tumor size predict risk of metastatic disease or prognosis of small renal cell carcinomas?
Answer: More than 85% of small solid renal tumors are renal cell carcinoma. The majority of localized small renal tumors can be cured with existing surgical approaches. However, there is a small but not insignificant risk of synchronous and metachronous metastatic disease and cancer associated death. Patients considering experimental therapies such as ablation and surveillance should be aware of this. Tumor size alone is not sufficient to distinguish renal cell carcinoma with benign behavior from aggressive small renal cell carcinoma. Survival of patients with small metastatic renal cell carcinoma is better then expected. The biology of these unique tumors should be further studied.

A:
no
