Fluoroscopy-Guided Percutaneous Transpedicular Biopsy Versus Posterolateral Endoscopy for Infective Spondylodiskitis Diagnosis: A Comparative Study.

OBJECTIVE: We sought to determine the concordance in frequency of microbiologic isolation and species identification in specimens obtained by 2 methods. METHODS: Intervertebral disk specimens were taken simultaneously from each patient using percutaneous needle and posterolateral endoscopic biopsies. The isolates were reported in frequencies and concordance using the chi square and Cohen kappa tests. RESULTS: Thirty patients were recruited. The average age was 58.1 years, and 15 patients were women. The clinical evolution time was 7 ± 4 months. The causative organism was identified in 12 (40%) specimens obtained by fluoroscopy-guided percutaneous transpedicular biopsy and in 14 (46.6%) obtained by posterolateral endoscopy. The most common organism isolated was Staphylococcus aureus in 3 patients with the percutaneous technique and in 5 with the endoscopic one; Escherichia coli was isolated in 3 patients with each method. The kappa test showed a high degree of agreement between both methods (kappa = 0.86); the agreement in bacterial species identification was 100%. CONCLUSIONS: Fluoroscopy-guided percutaneous biopsy and endoscopic sampling have a good degree of concordance for both, frequency of organism isolation and identification in patients with infectious spondylodiskitis.

Nonintensivist Training to Increase the Staff Capacity of Intensive Care Units During COVID-19 Pandemic Surge in Argentina.

OBJECTIVE: The aim of this study was to report the results of a nationwide critical-care course for non-intensivists to increase staff capacity of intensive care units (ICUs) during the coronavirus disease 2019 (COVID-19) pandemic in Argentina. METHODS: Three academic organizations, with special funding from 55 private companies, developed a short virtual course comprised of Web-based videos, virtual tutorials, and a forum chat. Each state assigned scholarships to non-ICU staff from public hospitals. Students received active follow-up for the completion of the course and took a survey upon course completion. RESULTS: After 4 m, there were 10,123 students registered from 661 hospitals in 328 cities. Of these, 67.8% passed the course, 29.1% were still ongoing, and 3.1% were inactive. Most students were female (74.2%) with a median of 37 y old (IQR 31-44). The group was composed of 56.5% nurses, 36.2% physicians, and 7.4% physiotherapists, of whom 48.3% did not have any experience in critical care. Mean overall satisfaction was 4.4/5 (standard deviation, 0.9), and 90.7% considered they were able to apply the contents to their practice. CONCLUSIONS: This course was effective for rapid training of non-ICU personnel. The assignment strategy, the educational techniques, and the close follow-up led to low dropout and high success rates and satisfaction.
