    Clinical Epidemiology and Outcomes of Pediatric Musculoskeletal Infections
    (Elsevier, 2021) Yi, Jumi; Wood, James B.; Creech, C. Buddy; Williams, Derek; Jimenez-Truque, Natalia; Yildirim, Inci; Sederdahl, Bethany; Daugherty, Michael; Hussaini, Laila; Munye, Mohamed; Tomashek, Kay M.; Focht, Christopher; Watson, Nora; Anderson, Evan J.; Thomsen, Isaac; Pediatrics, School of Medicine
    Objectives: To understand the epidemiology of acute hematogenous osteomyelitis and septic arthritis, including clinical and demographic features, microbiology, treatment approaches, treatment-associated complications, and outcomes. Study design: Retrospective cohort study of 453 children with acute hematogenous osteomyelitis and/or septic arthritis from 2009 to 2015. Results: Among the 453 patients, 218 (48%) had acute hematogenous osteomyelitis, 132 (29%) had septic arthritis, and 103 (23%) had concurrent acute hematogenous osteomyelitis/septic arthritis. Treatment failure/recurrent infection occurred in 41 patients (9%). Patients with concurrent acute hematogenous osteomyelitis/septic arthritis had longer hospital stays, longer duration of antibiotic therapy, and were more likely to have prolonged bacteremia and require intensive care. Staphylococcus aureus was identified in 228 (51%) patients, of which 114 (50%) were methicillin-resistant S aureus. Compared with septic arthritis, acute hematogenous osteomyelitis and concurrent acute hematogenous osteomyelitis/septic arthritis were associated with higher odds of treatment failure (OR, 8.19; 95% CI, 2.02-33.21 [P = .003]; and OR, 14.43; 95% CI, 3.39-61.37 [P < .001], respectively). The need for more than 1 surgical procedure was also associated with higher odds of treatment failure (OR, 2.98; 95% CI, 1.18-7.52; P = .021). Early change to oral antibiotic therapy was not associated with treatment failure (OR, 0.64; 95% CI, 0.24-1.74; P = .386). Most (73%) medically attended treatment complications occurred while on parenteral therapy. Conclusions: Musculoskeletal infections are challenging pediatric infections. S aureus remains the most common pathogen, with methicillin-resistant S aureus accounting for 25% of all cases. Concurrent acute hematogenous osteomyelitis/septic arthritis is associated with more severe disease and worse outcomes. Fewer treatment-related complications occurred while on oral therapy. Early transition to oral therapy was not associated with treatment failure.

    Performance of TEM-PCR vs Culture for Bacterial Identification in Pediatric Musculoskeletal Infections
    (Oxford Academic, 2018-05-22) Wood, James B.; Sesler, Cheryl; Stalons, Donald; Grigorenko, Elena; Schoenecker, Jonathan G.; Creech, C. Buddy; Thomsen, Isaac P.; Pediatrics, School of Medicine
    Improved diagnostics are needed for children with musculoskeletal infections (MSKIs). We assessed the performance of target-enriched multiplex polymerase chain reaction (TEM-PCR) in children with MSKI. TEM-PCR was concordant with culture in pathogen identification and antibiotic susceptibility testing, while increasing the overall yield of pathogen detection. This technology has the potential to inform judicious antimicrobial use early in the disease course.
