Randomized Controlled Trial
Alterations of hemostasis after laparoscopic and open surgery.
After tissue injury caused by trauma or surgery, alterations of hemostasis are observed and there is a risk for postoperative thromboembolic complications. Laparoscopic surgery, by causing limited tissue injury, appears to be associated with a lower risk for thromboembolism than open surgery. We conducted a prospective randomized study in order to detect potentially existing differences in activation of coagulation and fibrinolytic pathways between open and laparoscopic surgery. ⋯ Open surgery as compared to laparoscopic procedures leads to activation of the clotting system of a higher degree. Although of a lower degree, hypercoagulability is still observed in patients undergoing laparoscopic surgery and, therefore, routine thromboembolic prophylaxis should be considered.

Randomized Controlled Trial
Once weekly recombinant human erythropoietin treatment for cancer-induced anemia in children with acute lymphoblastic leukemia receiving maintenance chemotherapy: a randomized case-controlled study.
Patients receiving chemotherapy for cancer often develop anemia, which can contribute to increased morbidity and reduced quality of life (QOL). Chemotherapy-induced anemia can be successfully treated using recombinant human erythropoietin (rHuEPO). ⋯ Treatment with QW epoetin-alpha was found to increase Hb levels, decrease transfusion requirement, and improve functional status and QOL in anemic patients with ALL in maintenance receiving chemotherapy. The once-weekly schedule is convenient, safe, and may reduce the burden on patients, parents, and their caregivers by reducing the number of visits to the clinic.
