Labeled white blood cell/bone marrow single-photon emission computed tomography with computed tomography fails in diagnosing chronic periprosthetic shoulder joint infection.

J Shoulder Elbow Surg 2019 Jan 31. Epub 2019 Jan 31.

Department of Orthopedics, Horsens Regional Hospital, Horsens, Denmark.

Background: Shoulder periprosthetic joint infections (PJI) caused by low-virulent bacteria pose a diagnostic challenge. Combined labeled leukocyte (WBC) and technetium 99m sulfur colloid bone marrow imaging (WBC/BM) is considered the radionuclide imaging gold standard for diagnosing lower limb PJI. However, it is laborious and expensive to perform, and documentation on shoulder arthroplasties is lacking. Read More

Intervertebral disc penetration by antibiotics used prophylactically in spinal surgery: implications for the current standards and treatment of disc infections.

Eur Spine J 2018 Dec 1. Epub 2018 Dec 1.

Central European Institute of Technology (CEITEC), Masaryk University, Kamenice 753/5, 625 00, Brno, Czech Republic.

Purpose: The presence of Propionibacterium acnes in a substantial component of resected disc specimens obtained from patients undergoing discectomy or microdiscectomy has led to the suggestion that this prominent human skin and oral commensal may exacerbate the pathology of degenerative disc disease. This hypothesis, therefore, raises the exciting possibility that antibiotics could play an important role in treating this debilitating condition. To date, however, little information about antibiotic penetration into the intervertebral disc is available. Read More

PLoS One 2018 29;13(11):e0208144. Epub 2018 Nov 29.

Central European Institute of Technology (CEITEC), Masaryk University, Brno, Czech Republic.

Most patients with chronic lower back pain (CLBP) exhibit degenerative disc disease. Disc specimens obtained during initial therapeutic discectomies are often infected/colonized with Propionibacterium acnes, a Gram-positive commensal of the human skin. Although pain associated with infection is typically ascribed to the body's inflammatory response, the Gram-positive bacterium Staphylococcus aureus was recently observed to directly activate nociceptors by secreting pore-forming α-hemolysins that disrupt neuronal cell membranes.

High prevalence of bacteria in clinically aseptic non-unions of the tibia and the femur in tissue biopsies.

Eur J Trauma Emerg Surg 2018 Sep 25. Epub 2018 Sep 25.

Department of Traumatology and Orthopedic Surgery, Cologne-Merheim Medical Center (CMMC), University Witten-Herdecke (UWH), Ostmerheimerstr. 200, 51109, Cologne, Germany.

Purpose: There are several hints that bacterial colonization might be an often overseen cause of non-union. Modern procedures like PCR have been reported to diagnose bacterial colonization with a high degree of accuracy. While PCR is not ubiquitously available, we hypothesize that biopsies from the non-union site are comparable to PCR results reported in the literature. Read More

Is IL-1β Further Evidence for the Role of in Degenerative Disc Disease? Lessons From the Study of the Inflammatory Skin Condition Acne Vulgaris.

Front Cell Infect Microbiol 2018 14;8:272. Epub 2018 Aug 14.

Central European Institute of Technology, Masaryk University, Brno, Czechia.

The pathogenesis of degenerative disc disease is a complex and multifactorial process in which genetics, mechanical trauma, altered loading and nutrition present significant etiological factors. Infection of the intervertebral disc with the anaerobic bacterium is now also emerging as a potentially new etiological factor. This human commensal bacterium is well known for its long association with the inflammatory skin condition acne vulgaris. Read More

Sonication of heart valves detects more bacteria in infective endocarditis.

Sci Rep 2018 Aug 28;8(1):12967. Epub 2018 Aug 28.

Department of Medical Microbiology and Infection Prevention, University of Groningen, University Medical Center Groningen, Groningen, The Netherlands.

Optimal antimicrobial treatment of infective endocarditis requires identification and susceptibility patterns of pathogens. Sonication of explanted heart valves could increase the identification and culture of pathogens, as shown in prosthetic joint and pacemaker/ICD infections. We tested 26 explanted heart valves from 20 patients with active definite endocarditis for added diagnostic value of sonication to the standard microbiological workup in a prospective diagnostic proof of concept study.
