Septic complications are an important factor for the morbidity and mortality of acute pancreatitis. The gut has been identified as a source of infection early in the course of the disease allowing intestinal bacteria to translocate into pancreatic necrosis and other organs. Bacterial translocation is promoted by an impaired intestinal mucosal barrier which can be attributed to the reduced oxygen and substrate supply of the intestine during the early systemic response to the pancreatic injury. ⋯ Experimental data are presented to underline the significance of these nutritive factors and subsequent randomized multicenter trials performed to verify the positive experimental results are introduced. The effect of other nutritive factors (e.g. omega-3-fatty acids) has not yet been systemically investigated. Thus, experimental and clinical studies need to be performed for evaluating their effect on bacterial translocation and the disease course in acute pancreatitis.

Periprosthetic femoral shaft fracture represents an uncommon but potentially devastating complication associated with total hip arthroplasty. The treatment should result in complete union of the fracture and at the same time guarantee stability of the implant. 15 patients treated between 1992 to 1998 were analysed. Clinical and radiographic follow-up averaged 30 months (6-79 months) in 13 cases. ⋯ The average Harris score was 70 (26-93). For fractures near the femoral stem or in case of implant loosening we recommend the shift to a long stem prosthesis. Also in fractures distally from the femoral stem tip we prefer now long stem implants rather than plate fixation to avoid large exposure of the femoral shaft and resultant complications.
