Randomized Controlled Trial Comparative Study Clinical TrialCoronary artery disease and upper abdominal surgery: impact of anesthesia on perioperative myocardial ischemia.
Some papers claim that epidural anesthesia and analgesia lowers the incidence of perioperative ischemic events and may have a favorable effect on perioperative cardiac morbidity and mortality. We studied the effect of epidural anesthesia and analgesia on perioperative myocardial ischemia, in a group of patients with known coronary artery disease, who underwent upper abdominal surgery. ⋯ Epidural anesthesia and analgesia reduces intraoperative and early postoperative ischemia in patients with known coronary artery disease undergoing upper abdominal surgery.

Randomized Controlled Trial Clinical TrialTranscatheter arterial chemoembolization for hepatocellular carcinoma in patients with cirrhosis: evaluation of two kinds of dosages of anticancer drugs and analysis of prognostic factors.
To evaluate the efficacy of TACE (transcatheter arterial chemoembolization) with use of low-dose versus conventional-dose anticancer drugs in hepatocellular carcinoma patients with cirrhosis and to analyze their prognostic factors. ⋯ TACE with use of large-dose anticancer drugs does not significantly enhance the anticancer effects and survival compared that with lowdose anticancer drugs. The therapeutic effect of TACE was mainly attributed to embolization of the artery rather than to anticancer drugs.

Comparative StudyInnovative chemotherapies for stage III colon cancer: a cost-effectiveness study.
The lower mortality rate associated with Oxaliplatin or Irinotecan added to Fluorouracil chemotherapy for stage III colon cancer should outweigh significantly higher costs of these therapies. While efficacy data currently are lacking, our aim was to generate cost-effectiveness data about a range of potential benefits to define the increase in mortality reduction required for the future acceptance of these new chemotherapies. ⋯ Even the most conservative scenario showed a discounted cost-effectiveness ratio of only 12,485 per life year gained, when compared to best supportive care and therefore met strict cost-effectiveness standards. Oxaliplatin chemotherapy should be accepted for all patients with stage III colon cancer if the required 20% increase in mortality reduction is achieved. Because of the high impact on cost-effectiveness each more expensive chemo-therapy schedule with higher overall dosage should first prove its superior clinical efficacy.

Prevalence of pulmonary hypertension in patients with hepatosplenic Mansonic schistosomiasis--prospective study.
Thirty-four patients with portal hypertension and previous history of esophageal varices hemorrhage due to hepatosplenic Mansonic schistosomiasis were prospectively studied. ⋯ In conclusion, pulmonary hypertension is a frequent complication in patients with portal hypertension due to hepatosplenic Mansonic schistosomiasis and, in 20.6% of the cases, it can be considered as moderate or severe. Our results suggest that shunt surgeries, which can aggravate pulmonary hypertension, should be employed very cautiously in the treatment of schistosomal portal hypertension.

Resection of localized recurrences after hepatectomy of colorectal cancer metastases.
Hepatectomy is generally considered the only mode of curative treatment available for patients with colorectal liver metastases, even though recurrence occurs in more than 60% of the patients. ⋯ In appropriately selected patients with colorectal cancer, surgical excision of localized recurrences after hepatectomy may be effective in prolonging survival.
