ABSTRACT
Penetration of levofloxacin and moxifloxacin into cancellous and cortical bone was studied using high-performance liquid chromatography (HPLC) in 16 patients who underwent routine total hip arthroplasty. Our results demonstrate a good degree of penetration into bone for both quinolones. The mean cancellous penetration was 53.86% for moxifloxacin and 54.13% for levofloxacin. The penetration into cortical bone was 41.59% and 34.26% respectively. The concentrations for both quinolones were above the minimum inhibitory concentration (MIC(90s)) for the most common pathogens, so they can be used for the treatment of osteomyelitis.

A comparison of the outcome of 66 patients with complicated colorectal cancer (CRC) who underwent an emergency operation and 217 electively operated patients in an 11-year period was retrospectively determined. The complications presented on admission were obstruction (13.4%), perforation with peritonitis (6.36%), obstruction and perforation (1.4%) and massive bleeding (2.1%). The majority of the patients electively treated were of stages II and III (45.5% and 29%) and those urgently operated on were stages III and IV (67.7% and 14.1%) respectively. Radical resections were performed in 45 patients and palliative in 21. Only ten patients from the urgently treated are still alive and free of the disease. In conclusion, the treatment of complicated CRC carries a considerable incidence of complications, morbidity and mortality, and the overall 5-year survival rate is disappointing compared to electively treated patients.
