Case ReportsGiant mixed-type liposarcoma of the mesentery: case report.
Primary mesenteric liposarcomas are very rare, especially when they are of mixed histologic pattern. Patient prognosis is based upon the most aggressive histologic type of liposarcoma. A case is reported of a 77-year-old man with a history of slowly increasing abdominal volume over 3 years. ⋯ Although this type of tumor is rare, tumor tissue should be thoroughly collected and analyzed on histologic examination to reach definitive diagnosis. Recognition of the underappreciated subtype of liposarcoma is important for proper prognosis and treatment of the patient. According to our knowledge, this is the largest size of mixed-type mesenteric liposarcoma described in the English literature.

Analysis of blood pressure changes in patients undergoing total hip or knee replacement in spinal and general anesthesia.
The aim of this study was to analyze hemodynamic changes in hypertensive and normotensive patients undergoing total hip or knee replacement in spinal and general anesthesia. Eighty patients who underwent total hip or knee replacement surgery in the period between July 2010 and February 2011 at Sveti Duh University Hospital were retrospectively evaluated. Seventeen patients underwent the operation in general anesthesia and 63 patients in regional anesthesia. ⋯ The difference between the highest and the lowest intraoperative systolic blood pressure was significantly greater in hypertensive patients undergoing the operation in regional anesthesia compared to normotensive patients (46.41 mm Hg vs. 35.88 mm Hg, P<0.05). The results presented in this paper indicate that the fluctuations of intraoperative blood pressure were greater and the highest intraoperative systolic blood pressure was higher in hypertensive compared to normotensive patients undergoing the operation in regional anesthesia. In our study, there were no significant differences in intraoperative blood pressure between hypertensive and normotensive patients who underwent the operation in general anesthesia.
