Clinical and ultrasound features of 46 children with suppurative osteoarthritis: experience from two centers.

OBJECTIVE: Diagnosing musculoskeletal infections in children is challenging. In recent years, with the advancement of ultrasound technology, high-resolution ultrasound has unique advantages for musculoskeletal children. The aim of this work is to summarize the ultrasonographic and clinical characteristics of children with pyogenic arthritis and osteomyelitis. This study provides a simpler and more effective diagnostic basis for clinical treatment. METHODS: Fifty children with osteomyelitis or arthritis were diagnosed via ultrasound, and the results of the ultrasound diagnosis were compared with those of magnetic resonance imaging and surgery. Clinical and ultrasound characteristics were also analyzed. RESULTS: Out of 50 patients, 46 were confirmed to have suppurative infection by surgical and microbiological examination. Among these 46 patients, 26 were diagnosed with osteomyelitis and 20 had arthritis. The manifestations of osteomyelitis were subperiosteal abscess (15 patients), bone destruction (17 patients), bone marrow abscess (9 patients), and adjacent joint abscess (13 patients). Osteomyelitis mostly affects the long bones of the limbs, femur and humerus (10 and 9 patients, respectively), followed by the ulna, radius, tibia and fibula (one patient each). The manifestations of arthritis were joint pus (20 patients) and joint capsule thickening (20 patients), and hip dislocation (8 patients). All the patients had arthritis involving the hip joint. CONCLUSION: Subperiosteal abscess, bone destruction, and joint abscess with dislocation are ultrasonographic features of pyogenic osteoarthritis. The findings of this work can improve the early diagnosis and differentiation of pyogenic osteoarthritis and provide a reliable basis for treatment.

Chronic Nonspinal Osteomyelitis in Adults: Consensus Recommendations on Percutaneous Bone Biopsies from the Society of Academic Bone Radiologists.

The diagnosis and management of chronic nonspinal osteomyelitis can be challenging, and guidelines regarding the appropriateness of performing percutaneous image-guided biopsies to acquire bone samples for microbiological analysis remain limited. An expert panel convened by the Society of Academic Bone Radiologists developed and endorsed consensus statements on the various indications for percutaneous image-guided biopsies to standardize care and eliminate inconsistencies across institutions. The issued statements pertain to several commonly encountered clinical presentations of chronic osteomyelitis and were supported by a literature review. For most patients, MRI can help guide management and effectively rule out osteomyelitis when performed soon after presentation. Additionally, in the appropriate clinical setting, open wounds such as sinus tracts and ulcers, as well as joint fluid aspirates, can be used for microbiological culture to determine the causative microorganism. If MRI findings are positive, surgery is not needed, and alternative sites for microbiological culture are not available, then percutaneous image-guided biopsies can be performed. The expert panel recommends that antibiotics be avoided or discontinued for an optimal period of 2 weeks prior to a biopsy whenever possible. Patients with extensive necrotic decubitus ulcers or other surgical emergencies should not undergo percutaneous image-guided biopsies but rather should be admitted for surgical debridement and intraoperative cultures. Multidisciplinary discussion and approach are crucial to ensure optimal diagnosis and care of patients diagnosed with chronic osteomyelitis.

Enhanced Chemoradiotherapy for MRSA-Infected Osteomyelitis Using Immunomodulatory Polymer-Reinforced Nanotherapeutics.

The eradication of osteomyelitis caused by methicillin-resistant Staphylococcus aureus (MRSA) poses a significant challenge due to its development of biofilm-induced antibiotic resistance and impaired innate immunity, which often leads to frequent surgical failure. Here, the design, synthesis, and performance of X-ray-activated polymer-reinforced nanotherapeutics that modulate the immunological properties of infectious microenvironments to enhance chemoradiotherapy against multidrug-resistant bacterial deep-tissue infections are reported. Upon X-ray radiation, the proposed polymer-reinforced nanotherapeutic generates reactive oxygen species and reactive nitrogen species. To robustly eradicate MRSA biofilms at deep infection sites, these species can specifically bind to MRSA and penetrate biofilms for enhanced chemoradiotherapy treatment. X-ray-activated nanotherapeutics modulate the innate immunity of macrophages to prevent the recurrence of osteomyelitis. The remarkable anti-infection effects of these nanotherapeutics are validated using a rat osteomyelitis model. This study demonstrates the significant potential of a synergistic chemoradiotherapy and immunotherapy method for treating MRSA biofilm-infected osteomyelitis.

A Smart Bacteria-Capture-Killing Vector for Effectively Treating Osteomyelitis Through Synergy Under Microwave Therapy.

Osteomyelitis caused by deep tissue infections is difficult to cure through phototherapy due to the poor penetration depth of the light. Herein, Cu/C/Fe3O4-COOH nanorod composites (Cu/C/Fe3O4-COOH) with nanoscale tip convex structures are successfully fabricated as a microwave-responsive smart bacteria-capture-killing vector. Cu/C/Fe3O4-COOH exhibited excellent magnetic targeting and bacteria-capturing ability due to its magnetism and high selectivity affinity to the amino groups on the surface of Staphylococcus aureus (S. aureus). Under microwave irradiation, Cu/C/Fe3O4-COOH efficiently treated S. aureus-infected osteomyelitis through the synergistic effects of microwave thermal therapy, microwave dynamic therapy, and copper ion therapy. It is calculated the electric field intensity in various regions of Cu/C/Fe3O4-COOH under microwave irradiation, demonstrating that it obtained the highest electric field intensity on the surface of copper nanoparticles of Cu/C/Fe3O4-COOH due to its high-curvature tips and metallic properties. This led to copper nanoparticles attracted more charged particles compared with other areas in Cu/C/Fe3O4-COOH. These charges are easier to escape from the high curvature surface of Cu/C/Fe3O4-COOH, and captured by adsorbed oxygen, resulting in the generation of reactive oxygen species. The Cu/C/Fe3O4-COOH designed in this study is expected to provide insight into the treatment of deep tissue infections under the irradiation of microwave.

Musculoskeletal Infection: Role of Molecular Imaging in Diagnosis and Monitoring Treatment Response.

Molecular imaging tests frequently are performed as part of the diagnostic workup of musculoskeletal infection. Three-phase bone scintigraphy reliably diagnoses osteomyelitis in bones not affected by underlying conditions. The test is less useful, because of decreased specificity, in patients with underlying bony abnormalities or alterations such as fractures, orthopaedic hardware, arthritic changes, and tumors. At one time gallium-67 scintigraphy was used as a complement to bone scintigraphy to improve the specificity of diagnosis. With the introduction of labeled leukocytes and, more recently, fluorine-18 fluorodeoxyglucose, gallium-67 is reserved primarily for spinal infections when fluorine-18 fluorodeoxyglucose is not available. Except for the spine, in vitro labeled leukocyte imaging is valuable for diagnosing osteomyelitis in the setting of underlying osseous abnormalities. Leukocytes accumulate in bone marrow as well as in the presence of infection. Performing complementary bone marrow imaging with technetium-99m sulfur colloid facilitates the differentiation between the two and improves test accuracy. Fluorine-18 fluorodeoxyglucose accurately diagnoses spondylodiskitis and diabetic foot osteomyelitis, but its value in periprosthetic joint infection has yet to be determined.

Absceso de Brodie en la clavícula: una forma poco frecuente de presentación / Brodie abscess in the clavicle: an uncommon presentation

La osteomielitis (OM) se define como la inflamación ósea de origen infeccioso. La forma aguda es frecuente en la edad pediátrica. El absceso de Brodie es un tipo de osteomielitis subaguda, históricamente con baja incidencia, pero que actualmente se presenta un aumento de la misma. De poca repercusión clínica, con pruebas de laboratorio inespecíficas y estudios radiológicos de difícil interpretación, es crucial la sospecha diagnóstica. Se asemeja a procesos neoplásicos, benignos o malignos. Recae en la experiencia del profesional realizar el diagnóstico adecuado. El tratamiento consiste en antibioticoterapia, tanto parenteral como por vía oral, y eventualmente drenaje quirúrgico. Presentamos una paciente sana que consultó por una tumoración en topografía de clavícula izquierda de 3 meses de evolución. Se realizó diagnóstico de absceso de Brodie, inició tratamiento y se obtuvo una buena respuesta. Resulta imprescindible tener un alto índice de sospecha de esta entidad para no someter al paciente a estudios, pruebas invasivas o tratamientos erróneos, y evitar secuelas a futuro.

Osteomyelitis is defined as an inflammation of the bone caused by infection. Acute osteomyelitis is common in pediatrics. A Brodie abscess is a type of subacute osteomyelitis, with a historically low incidence; however, its incidence is currently increasing. Given its little clinical impact, with non-specific laboratory tests and radiological studies of difficult interpretation, diagnostic suspicion is crucial. It resembles neoplasms, either benign or malignant. An adequate diagnosis falls on the health care provider's experience. Treatment consists of antibiotics, both parenteral and oral, with potential surgical drainage. Here we describe the case of a healthy female patient with a tumor found in the topography of the left clavicle 3 months before. She was diagnosed with Brodie abscess; treatment was started with a good response. A high index of suspicion of Brodie abscess is critical to avoid invasive tests and studies or inadequate treatments, and to prevent future sequelae.

Acute osteomyelitis, thrombophlebitis, and pulmonary embolism: a case report.

BACKGROUND: Septic pulmonary embolism (SPE), deep vein thrombophlebitis (DVT), and acute osteomyelitis (AOM) form a triad that is rarely seen in children and is usually associated with a history of trauma on long bones. Unfortunately, a delay in diagnosis is frequently observed in this syndrome, which places the patient at risk of life-threatening complications. This delay can largely be attributed to the failure to consider osteomyelitis as a potential underlying cause of DVT. CASE PRESENTATION: In this case report, we present the case of a 16-year-old Arabian male who presented with limb trauma and fever. The patient had a delayed diagnosis of osteomyelitis, which resulted in the formation of an abscess and subsequent joint destruction. Surgical drainage and joint replacement surgery were deemed necessary for treatment. CONCLUSIONS: persistent fever along with a history of trauma on a long bone with signs of DVT of the limb in a child should raise concern for osteomyelitis and an MRI evaluation of the limb should be obtained.

Emphysematous osteomyelitis: a rare and aggressive disease.

Emphysematous osteomyelitis is an extremely rare entity consisting of the presence of intraosseous gas that can extend to the joints and adjacent soft tissues. It is an aggressive infectious process associated with high mortality, especially in patients with risk factors such as tumors or diabetes mellitus. Because early diagnosis and immediate treatment are crucial to prevent the potentially devastating consequences of this condition, imaging tests such as computed tomography play a fundamental role in its diagnosis and management. Therefore, radiologists must be aware that intraosseous gas is a rare but alarming sign that is pathognomonic of emphysematous osteomyelitis, especially in the axial skeleton.

Evaluation of the osteoconductivity and the degradation of novel hydroxyapatite/polyurethane combined with mesoporous silica microspheres in a rabbit osteomyelitis model.

Bone defects caused by osteomyelitis can lead to severe disability. Surgeons still face significant challenges in treating bone defects. Nano-hydroxyapatite (n-HA) plays an important role in bone tissue engineering due to its excellent biocompatibility and osteoconductivity. Levofloxacin (Levo) was encapsulated in mesoporous silica nanoparticles (MSNs) via electrostatic attraction to serve as a drug delivery system. MSNs were incorporated with n-HA and polyurethane (PU). The degradation and osteoconductivity properties of these novel composite scaffolds and their effectiveness in treating chronic osteomyelitis in a rabbit model were assessed. Gross pathology, radiographic imaging, micro-computed tomography, Van Gieson staining, and hematoxylin and eosin staining were conducted at 6 and 12 weeks. The group of composite scaffolds combining n-HA/PU with MSNs containing 5 mg Levo (n-HA/PU + Nano +5 mg Levo) composite scaffolds showed superior antibacterial properties compared to the other groups. At 12 weeks, the n-HA/PU + Nano +5 mg Levo composite scaffolds group exhibited significantly greater volume of new trabecular bone formation compared to the other three groups. The surface of the novel composite scaffolds exhibited degradation after 6 weeks implantation. The internal structure of the scaffolds collapsed noticeably after 12 weeks of implantation. The rate of material degradation corresponded to the rate of new bone ingrowth. This novel composite scaffold, which is biodegradable and osteoconductive, has potential as a drug delivery system for treating chronic osteomyelitis accompanied by bone defects.

Interfacial and Defect Polarization Enhanced Microwave Noninvasive Therapy for Staphylococcus aureus-Infected Chronic Osteomyelitis.

Chronic osteomyelitis (COM), is a long-term, constant, and intractable disease mostly induced by infection from the invasion of Staphylococcus aureus (S. aureus) into bone cells. Here, we describe a highly effective microwave (MW) therapeutic strategy for S. aureus-induced COM based on the in situ growth of interfacial oxygen vacancy-rich molybdenum disulfide (MoS2)/titanium carbide (Ti3C2Tx) MXene with oxygen-deficient titanium dioxide (TiO2-x) on Ti3C2Tx (labeled as HU-MoS2/Ti3C2Tx) by producing reactive oxygen species (ROS) and heat. HU-MoS2/Ti3C2Tx produced heat and ROS, which could effectively treat S. aureus-induced COM under MW irradiation. The underlying mechanism determined by density functional theory (DFT) and MW vector network analysis was that HU-MoS2/Ti3C2Tx formed a high-energy local electric field under MW irradiation, consequently generating more high-energy free electrons to pass and move across the interface at a high speed and accelerate by the heterointerface, which enhanced the charge accumulation on both sides of the interface. Moreover, these charges were captured by the oxygen species adsorbed at the HU-MoS2/Ti3C2Tx interface to produce ROS. MoS2 facilitated multiple reflections and scattering of electromagnetic waves as well as enhanced impedance matching. Ti3C2Tx enhanced the conduction loss of electromagnetic waves, while functional groups induced dipole polarization to enhance attenuation of MW.

[Current diagnosis and treatment of skull base osteomyelitis].

Skull base osteomyelitis is a rare, refractory, and potentially fatal disease primarily caused by otogenic and sino rhinogenic infections. At times, it can mimic neoplasia complicating the diagnosis. With the use of antibiotics, advancements in diagnostic methods, and skull base surgical techniques, the mortality rate has significantly improved. However, the successful diagnosis and treatment of the disease is still challenging due to delayed diagnosis, lengthy treatment course, a tendency for relapse and lack of guidelines. Therefore, this article aims to review the progress in the diagnosis and treatment of skull base osteomyelitis.

Skull Base Osteomyelitis: Historical Perspective, Diagnosis and Management Update.

SBO is a life-threatening disease that requires a high index of suspicion based on these patients complex underlying medical co-morbidities and clinician's acumen. Once a diagnosis is made, is it critical to communicate and work closely with other multidisciplinary teams (neuroradiology for appropriate choice of imaging study and interpretation; infectious disease for appropriate medical treatment and duration; internist to properly manage their underlying medical co-morbidities). Despite advances in imaging, the diagnosis is first made based on clinical judgment, appropriate culture, and tissue biopsy.

Vertebral osteomyelitis after spine instrumentation surgery: risk factors and management.

BACKGROUND: Vertebral osteomyelitis after spine instrumentation surgery (pVOM) is a rare complication. Most cases of infection occur early after surgery that involve skin and soft tissue and can be managed with debridement, antibiotics, and implant retention (DAIR). AIM: To identify pVOM risk factors and evaluate management strategies. METHODS: From a multicentre cohort of deep infection after spine instrumentation (IASI) cases (2010-2016), pVOM cases were compared with those without vertebral involvement. Early and late infections were defined (<60 days and >60 days after surgery, respectively). Multivariate analysis was used to explore risk factors. FINDINGS: Among 410 IASI cases, 19 (4.6%) presented with pVOM, ranging from 2% (7/347) in early to 19.1% (12/63) in late IASIs. After multivariate analysis, age (adjusted odds ratio (aOR): 1.10; 95% confidence interval (CI): 1.03-1.18), interbody fusion (aOR: 6.96; 95% CI: 2-24.18) and coagulase-negative staphylococci (CoNS) infection (aOR: 3.83; 95% CI: 1.01-14.53) remained independent risk factors for pVOM. Cases with pVOM had worse prognoses than those without (failure rate; 26.3% vs 10.8%; P = 0.038). Material removal was the preferred strategy (57.9%), mainly in early cases, without better outcomes (failure rate; 33.3% vs 50% compared with DAIR). Late cases managed with removal had greater success compared with DAIR (failure rate; 0% vs 40%; P = 0.067). CONCLUSION: Risk factors for pVOM are old age, use of interbody fusion devices and CoNS aetiology. Although the diagnosis leads to a worse prognosis, material withdrawn should be reserved for late cases or when spinal fusion is achieved.

Charcot neuroarthropathy versus osteomyelitis: a case series.

INTRODUCTION: Patients with diabetes and peripheral neuropathy have a 25% risk of developing a foot ulcer, and these can lead to soft tissue infections that worsen and result in osteomyelitis. While Charcot neuroarthropathy is not as common as osteomyelitis, it is often misdiagnosed as osteomyelitis. CASE REPORTS: Three patients presented with diabetes, neuropathy, and foot ulcers. They underwent prophylactic surgery but later developed swelling at the surgical sites. Radiographs showed fragmentations that caused concern about osteomyelitis. The authors maintained diagnoses of Charcot neuroarthropathy and treated the patients with immobilization and offloading. All patients resolved the fragmentations without antibiotics or surgery. CONCLUSION: While Charcot neuroarthropathy and osteomyelitis have similar signs and symptoms, understanding the similarities and differences between the conditions can aid providers in appropriate wound management.

An Update on Pediatric Acute Hematogenous Osteomyelitis in New Zealand - A Decade on.

INTRODUCTION: New Zealand (NZ) has high rates of pediatric acute hematogenous osteomyelitis (AHO) with males and children of Pasifika and Maori ethnicity overrepresented. AIMS: To update the incidence of Pediatric AHO over 10 years, identifying trends in presentation, organisms, treatment, and outcomes. METHODS: A 10-year retrospective review of children aged 6 weeks to 15 years admitted with Pediatric AHO across two centers from 2008 to 2017. Demographic data, features of presentation, investigations, management, and complications were collected. Incidence was calculated from census data. Data were compared with our osteomyelitis database from the previous decade. (1). RESULTS: 796 cases were identified. The incidence was 18 per 100,000 per annum. The average age was 7.7 years. Pasifika and Maori children are overrepresented (57%). 370 children (51%) came from low socioeconomic areas. Methicillin-sensitive Staphylococcus aureus was the most common pathogen (87%). Methicillin-resistant Staphylococcus aureus (MRSA) rates are low (4.4%). Forty-four (5.5%) children were admitted to the Pediatric Intensive Care Unit (PICU) with 9% mortality. The mean duration of antibiotics was 40 days. 325 children (41%) had surgery. Chronic infection has increased from 1.7% to 5.7%. CONCLUSIONS: NZ has high rates of AHO, however, the incidence has decreased from the previous decade. Males, those in low socioeconomic areas, Pasifika and Maori have high disease burden. The use of MRI as a diagnostic modality has increased. Future studies should focus on improving treatment via prospective analysis and reporting long-term morbidity to improve outcomes for children with severe disease and reduce rates of chronic infection.

Vertebral osteomyelitis due to Mycobacterium abscessus subsp. massiliense with paravertebral abscess: A case report and review.

The incidence of vertebral osteomyelitis (VO) caused by non-tuberculosis mycobacteria (NTM) without immunocompetence is extremely rare. Herein, we reported on a case of VO caused by NTM. A 38-year-old man was admitted to our hospital with persisting low back and leg pain which had lasted for a year. Before coming to our hospital, the patient was treated with antibiotics and iliopsoas muscle drainage. The biopsy confirmed the presence of a NTM, Mycobacterium abscessus subsp. massiliense. Several tests were conducted which showed the infection had progressively increased, such as vertebral endplate destruction on plain radiography, computed tomography scan, and epidural and paraspinal muscle abscesses on magnetic resonance imaging. The patient underwent radical debridement, anterior intervertebral fusion with bone graft, and posterior instrumentation with antibiotic administration. A year later, the patient's low back and leg pain was relieved without any analgetic. VO due to NTM is rare but can be treated with multimodal therapy.

[A vertebral polymicrobial osteomyelitis with atypicial microorganisms: A case report]. / Spondylodiscite, une bactérie peut en cacher une autre. Actualisation de la stratégie diagnostique et de suivi.

Vertebral Osteomyelitis (VO) is a rare disease, which has seen a gradual increase in its incidence over the past years. Here, we report a case, showing how difficult it can be to diagnose and manage a therapy in case of atypical microorganism. A 68-year-old man was hospitalized for a VO documented by blood cultures at Bacteroides fragilis. He first progressed favorably, but an increase in lumbar pain prompted, after an IRM, a percutaneous needle biopsy (PNB) that documented a recurrent VO at Corynebacterium striatum. In the face of this multi-microbial VO with atypicals microorganisms, a first PNB could have been discussed despite the positive blood cultures. This case report illustrates the complexity of management of VO, and its evolution according to the latest recommendations (interest of RMI during the follow-up, place of the TEP-scan, terms and conditions of immobilization, antibiotic administration methods).

Central Skull Base Osteomyelitis: A Case Series from a Tertiary Care Center Over 5 Years.

OBJECTIVE: Skull base osteomyelitis may rarely present in the sphenoid bone or clivus without an otologic source. This is referred to as central skull base osteomyelitis (CSBO). Knowledge regarding CSBO is limited to case reports and small case series. Here we present a case series to further describe typical patient characteristics, clinical presentation, and clinical course associated with this rare infection. METHODS: All patients treated at a single academic tertiary care institution for CSBO from 2016 through 2020 were identified. Inclusion criteria included culture proven CSBO without an otologic or iatrogenic source. Data were extracted via patient chart review and qualitatively analyzed. RESULTS: Seven patients were identified with CSBO, 5 male and 2 female. Age ranged from 63 to 87 (average 76). Risk factors included advanced age, diabetes, and history of radiation. The most common presenting symptom was headache (6), followed by otalgia (4). Two patients presented with cranial neuropathies. Diagnosis was facilitated by history and exam (including flexible laryngoscope exam), imaging (MRI), and labs (ESR). All patients received endoscopic biopsy and culture (most commonly polymicrobial, with diverse species). Treatment involved IV antibiotics, with a limited role for surgery. All patients survived and achieved resolution of infection. CONCLUSIONS: CSBO remains a diagnostic challenge due to its rarity and vague presenting symptoms that overlap with presentation of sinonasal malignancies. A high index of suspicion is required by the evaluating provider to ensure a timely diagnosis with early treatment in order to limit the significant morbidity which can be associated with this infection. LEVEL OF EVIDENCE: 4.

Antibiotic-loaded bone substitutes therapy in the management of the moderate to severe diabetic foot infection: A meta-analysis.

In recent years, local antibiotic-loaded bone substitutes (ALBS) have been used increasingly in the treatment of diabetic foot infection (DFI). The meta-analysis aimed to analyse the efficacy of ALBS on patients with moderate to severe DFI (with or without osteomyelitis). With an appropriate search strategy, 7 studies were selected for analysis (2 RCTs and 5 cohort studies). The result showed that the application of ALBS effectively reduced the length of hospital stay (WMD -5.55; 95% CI: -9.85 to -1.26; P = 0.01), the recurrence rates (RR 0.33; 95% CI: 0.15 to 0.69; P = 0.003) and the mortality rates (RR 0.22; 95% CI: 0.06 to 0.82; P = 0.02). Compared to the control groups, however, there was no difference in healing rates (RR 1.06; 95% CI: 0.96 to 1.18; P = 0.26), healing time (WMD -1.44; 95% CI: -3.37 to -0.49; P = 0.14), the number of debridement (WMD -1.98; 95% CI: -4.08 to 0.12; P = 0.06) and major amputation rates (RR 0.76; 95% CI: 0.35 to 1.61; P = 0.47). The ALBS appears to have some beneficial effects as an adjunct to standard surgery in the treatment of DFI with or without osteomyelitis, as it reduces recurrence rates, mortality rates, and length of hospital stay, but there was no statistically significant difference in enhancing wound healing.
