Randomized Controlled Trial Comparative Study
Early versus delayed laparoscopic cholecystectomy for acute cholecystitis: a prospective, randomized study.
We aimed to compare the clinical outcome and cost of early versus delayed laparoscopic cholecystectomy for acute cholecystitis. Sixty patients with acute cholecystitis were randomized into early (within 24 hours of admission) or delayed (after 6-8 weeks of conservative treatment) laparoscopic cholecystectomy groups. ⋯ Intraoperative and postoperative complications were recorded in 8 patients in the early laparoscopic cholecystectomy group, whereas no complications occurred in the delayed laparoscopic cholecystectomy group (P = 0.002). Despite intraoperative and postoperative complications being associated more with early laparoscopic cholecystectomy compared with delayed intervention, early laparoscopic cholecystectomy should be preferred for treatment of acute cholecystitis because of its advantages of shorter hospital stay and lower cost.

Review Case Reports
Gastric metastasis from renal cell carcinoma with gastrointestinal bleeding: a case report and review of the literature.
A 61-year-old man presented to our hospital with hypercalcemia and elevated C reactive protein (CRP). Evaluation revealed renal cell carcinoma (RCC) with metastasis to lung, bone, and brain. He underwent partial resection of the right kidney and a left nephrectomy. ⋯ His postoperative course was uneventful. However, 4 months after surgery, he died from brain metastasis. Metastatic RCC to the stomach, although rare, should be suspected in any patient with a history of RCC who presents with gastrointestinal symptoms.

Comparative Study
Comparing survival and recurrence in curative stage I to III colorectal cancer in transfused and nontransfused patients.
Evidence of the association between blood transfusions and its impact on prognostic outcomes in patients who undergo curative resection of colorectal cancer remains controversial. The aim of this study was to determine whether receiving peri-operative blood transfusions during curative colorectal cancer resection affected overall survival, cancer-related survival, and cancer recurrence. This retrospective study was undertaken at The Royal Brisbane and Women's Hospital, Australia, between 1984 and 2004. ⋯ Four hundred twenty three patients (30.9%) required transfusion and 947 patients (69.1%) did not. Peri-operative transfusion was associated with higher rates of cancer recurrence on multivariate analysis (P = 0.024, RR, 1.257, 95% CI, 1.03-1.53); however, it was not independently associated with poorer overall or cancer-related survival. Where the aim is curative resection, this study contributes to a body of evidence that blood transfusions may be associated with poorer outcomes.

The aim of this study was to compare the effects of four different topical antimicrobial dressings on a multi-drug resistant Pseudomonas aeruginosa contaminated full-thickness burn wound rat model. A total of 40 adult male Wistar albino rats were used. The control group (group 1), silver sulfadiazine (1%) group 2, chlorhexidine acetate (0.5%) group 3, citric acid (3%) group 4, and silver-coated dressing group 5 were compared to assess the antibacterial effects of a daily application to a 30% full-skin thickness burn wound seeded 10 minutes earlier with 10(8) CFU (colony forming unit)/0.5 mL of a multi-drug resistant Pseudomonas aeruginosa strain. ⋯ The tissue cultures from groups 2 and 5 exhibited significant differences compared to those of the other 3 groups, whereas no significant differences were observed between groups 1, 3, and 4. The effectiveness of the treatments was as follows: 1% silver sulfadiazine > silver-coated dressing > 3% citric acid > 0.5% chlorhexidine acetate > control group. Our results supported the efficacy of topical therapy by silver sulfadiazine and silver-coated dressing on infections caused by multi-drug resistant Pseudomonas spp.
