RESUMEN
The objective of this study was to determine whether use of mupirocin nasal ointment for perioperative eradication of Staphylococcus aureus nasal carriage is effective in preventing the development of surgical site infections (SSIs). A randomized, double-blind, placebo-controlled design was used. Either mupirocin or placebo nasal ointment was applied twice daily to 614 assessable patients from the day of admission to the hospital until the day of surgery. A total of 315 and 299 patients were randomized to receive mupirocin and placebo, respectively. Eradication of nasal carriage was significantly more effective in the mupirocin group (eradication rate, 83.5% versus 27.8%). In the mupirocin group, the rate of endogenous S. aureus infections was 5 times lower than in the placebo group (0.3% and 1.7%, respectively; relative risk, 0.19; 95% confidence interval, 0.02-1.62). Mupirocin nasal ointment did not reduce the SSI rate (by S. aureus) or the duration of hospital stay.

There is still debate as to the preferred extracorporeal treatment modality for severe lithium intoxication. Because lithium is readily diffusable, intermittent hemodialysis is usually performed. However, this bares the risk of a post-dialysis rebound concentration and, in the case of severe lithium poisoning collapse, aggravation of hemodynamic instability. Because of the relatively slow but continuous solute removal, continuous renal replacement therapy (CRRT) may be advantageous. We report the first case in the literature of severe lithium intoxication treated effectively with high-volume continuous venovenous hemofiltration (HV-CVVH). Results compared favorably to other forms of CRRT in terms of lithium clearance. Ease of implementation, the excellent tolerability and the superior lithium clearance without rebound phenomenon may make HV-CVVH the preferred treatment modality for severe lithium poisoning.

OBJECTIVE: To determine the relative importance of different risk factors for the development of surgical-site infections (SSIs) in orthopedic surgery with prosthetic implants. DESIGN: In a cohort of 272 patients, the following possible risk factors were studied: age, gender, method of hair removal, duration of operation, surgeon, underlying illness, and nasal carriage of Staphylococcus aureus. Infections were recorded following the Centers for Disease Control criteria. The relation between risk factors and SSI was tested in univariate and multiple logistic regression analysis. SETTING: Community hospital in Breda, The Netherlands. RESULTS: 18 (6.6%) of 272 patients experienced SSI: 11 superficial and 7 deep SSI. These infections led in three cases to removal of the prosthesis and caused 286 extra days in hospital. The main causative pathogen was S aureus. In multiple logistic regression analysis, the following factors were independent risk factors for the development of SSI: high-level nasal carriage of S aureus (P=.04), male gender (P=.005), and surgeon 1 (P=.006). The only independent risk factor for SSI with S aureus was high-level nasal carriage of S aureus (P=.002). CONCLUSION: High-level nasal carriage of S aureus was the most important and only significant independent risk factor for developing SSI with S aureus.
