Nontuberculous mycobacteria (NTM) are uncommon causes of cutaneous and musculoskeletal infections. Here, we present an immunocompromised patient with persistent swelling in the left hand, wrist, and distal forearm. MRI findings revealed flexor tenosynovitis with synovial hypertrophy of the left hand and wrist and loculated fluid containing rice bodies along the distal flexor digitorum muscles in the volar aspect of the left wrist. The patient underwent flexor tenosynovectomy, and histological examination of the excised tenosynovium and mass revealed noncaseating granulomas...

BACKGROUND: The most common organ affected due to tuberculosis (TB) is the lungs. Extrapulmonary TB is less common. Musculoskeletal organs are affected in around 8% of all tubercular patients, of which the spine is affected in almost half of the patients. The criteria for diagnosing spinal TB are quite difficult and we use an array of investigations for the same. METHODS: A retrospective study was carried out in the Neurosurgery and Microbiology Department at IMS and SUM Hospital between January 2021 and November 2023, and data were collected and tabulated in an Excel sheet...

BACKGROUND: Periprosthetic joint infection is a serious complication following joint replacement. The development of bacterial biofilms bestows antibiotic resistance and restricts treatment via implant retention surgery. Electromagnetic induction heating is a novel technique for antibacterial treatment of metallic surfaces that has demonstrated in-vitro efficacy. Previous studies have always employed stationary, non-portable devices. This study aims to assess the in-vitro efficacy of induction-heating disinfection of metallic surfaces using a new Portable Disinfection System based on Induction Heating...

BACKGROUND: Total humerus replacement (THR) is a reconstruction procedure performed after resection of massive humeral tumors. However, there is limited literature on the rates of failure and functional outcomes of this implant. Our study aimed to determine the main failure modes, implant survival, and postoperative functional outcomes of THR. METHODS: A comprehensive search of the PubMed and Embase databases was conducted. We registered our study on PROSPERO (448684) and used the Strengthening the Reporting of Observational Studies in Epidemiology checklist for quality assessment...

BACKGROUND: We aimed to test the hypothesis that development of metastatic infection represents a distinct clinical endpoint from death due to SAB. METHODS: We conducted a retrospective observational study of adults with SAB between 20/12/2019 and 23/08/2022 (n=464). Simple logistic regression, odds ratios, and z-scores were used to compare host, clinical and microbiologic features. RESULTS: Co-occurrence of attributable mortality and metastatic infection was infrequent...

BACKGROUND/OBJECTIVE: Post-COVID-19 subjects typically experience symptoms of fatigue, cognitive impairment, and sleep difficulty, which can be relieved by conventional aerobic exercise. Virtual Reality (VR) technology to support conventional exercise has recently gained much attention. Therefore, this study aimed to assess the effects of traditional treadmill exercise compared to virtual reality-simulated treadmill exercise on fatigue, cognitive function, sleep quality, and participant satisfaction with the exercise program in post-COVID-19 subjects...

BACKGROUND: X-linked hypophosphatemia (XLH) is a rare, progressive disorder characterized by excess fibroblast growth factor 23 (FGF23), causing renal phosphate-wasting and impaired active vitamin D synthesis. Burosumab is a recombinant human monoclonal antibody that inhibits FGF23, restoring patient serum phosphate levels. Safety data on long-term burosumab treatment are currently limited. OBJECTIVES: This post-authorization safety study (PASS) aims to monitor long-term safety outcomes in children and adolescents (1-17 years) treated with burosumab for XLH...

The use of routine ionizing imaging in identify and classify patients with dislocation or infection after surgery has some medical contraindication, in addition to risks associated with the ionizing load and elevated costs. A novel, less expensive and non-ionizing imaging technique, called infrared thermal imaging, can be proposed as a complementary method to routinely evaluate hip prosthesis patients and track their inflammation response following serious complications. Here we report a case of a total hip prosthesis which was dislocated during inpatient rehabilitation, and ultimately reduced without surgical procedure...

INTRODUCTION: Patients submitted to heart surgery are restricted to the bed of the Intensive Care Units (ICUs), due to this period of immobility the individual is likely to present clinical and functional alterations. These complications can be avoided by early mobilization; however, in some hospitals, this is not feasible due to the use of subxiphoid drain in the immediate postoperative period. OBJECTIVE: To verify the safety and feasibility of mobilizing patients after cardiac surgery using subxiphoid drain...

BACKGROUND: This study aimed to evaluate the application of metagenomic next-generation sequencing (mNGS) technology to identify pathogens in periprosthetic joint infection (PJI). METHODS: A retrospective analysis was conducted on 65 patients suspected of having PJI between April 2020 and July 2023. The patients were categorized into PJI (46 patients) and non-PJI (19 patients) groups based on the 2018 International Consensus Meeting criteria. Clinical data were collected, and both conventional bacterial culture and mNGS were performed...

OBJECTIVE: To investigate the associations of cumulative voriconazole dose, treatment duration, and alkaline phosphatase with voriconazole-induced periostitis. MATERIALS AND METHODS: One hundred and thirty-one patients with voriconazole use were identified using a clinical informatics tool. Health record data including age, sex, immune status, alkaline phosphatase, voriconazole levels, voriconazole dose, frequency, and treatment duration were collected. Imaging studies during the duration of treatment were reviewed by two radiology trainees and imaging features of voriconazole-induced periostitis were confirmed by a board-certified musculoskeletal radiologist...

BACKGROUND: In periprosthetic joint infections (PJIs), the surgeon's role becomes pivotal in addressing the infection locally, necessitating the surgical removal of infected and necrotic tissue. Opportunity to enhance the visualization of infected tissue during surgery could represent a game-changing innovation. OBJECTIVE: The aim of this narrative review is to delineate the application of intraoperative fluorescence imaging for targeting infected tissues in PJIs...

INTRODUCTION: Gout is a chronic disease characterized by deposition of monosodium urate crystals. Tophi develop in some individuals with untreated or uncontrolled gout, which leads to ulcerations, cosmetic problems, mechanical obstruction of joint movement, joint damage and musculoskeletal disability. Currently, the treatment of gouty tophi is controversial and challenging. Both surgical and internal medical treatments have limitations and require further exploration in clinical practice...

OBJECTIVE: To compare Frozen Section (FS) results during the reimplantation stage of revision knee arthroplasty, in patients without clinical signs of infection but with preoperative inconclusive serum inflammatory markers. METHODS: Sections were revisited the day after surgery. Intraoperative FS (iFS) was accepted as positive when the presence of >5 polymorphonuclear neutrophils (PMNLs) in 5 separate high-power fields was determined according to the consensus criteria of the International Consensus on Musculoskeletal Infection...

BACKGROUND: Customized 3D-printed pelvic implants with a porous structure have revolutionized periacetabular pelvic defect reconstruction after tumor resection, offering improved osteointegration, long-term stability, and anatomical fit. However, the lack of an established classification system hampers implementation and progress. METHODS: We formulated a novel classification system based on pelvic defect morphology and 3D-printed hemipelvis endoprostheses. It integrates surgical approach, osteotomy guide plate and prosthesis design, postoperative rehabilitation plans, and perioperative processes...

BACKGROUND: Pyomyositis, a bacterial muscle infection, is an important differential diagnosis in children and adolescents with musculoskeletal pain. In contrast to tropical regions, it is rarely recognized in temperate countries, but incidence is increasing and major studies are missing. METHODS: This retrospective multicenter study included patients <18 years of age hospitalized with pyomyositis in 11 Swiss children's hospitals between January 2010 and December 2022...

INTRODUCTION: Limb reconstruction surgery (LRS) has a wide range of clinical applications within orthopaedic and trauma surgery. We sought a consensus view from limb reconstruction healthcare practitioners across the United Kingdom to help guide research priorities within LRS. Our aim is to guide future clinical research in LRS, and assist healthcare practitioners, clinical academics, and funding bodies in identifying key research priorities to improve patient care. MATERIALS AND METHODS: A modified Delphi approach was used; it involved an initial scoping survey and a 2-round Delphi process to identify the consensus research priorities in both adult and paediatric LRS...

Staphylococcus aureus is found in the normal skin and mucosa of approximately 30% of healthy populations and is the most common pathogen in human disease associated with bacteria. They are divided into methicillin-sensitive S . aureus (MSSA) and methicillin-resistant S. aureus (MRSA). The S. aureus strains carrying the Panton-Valentine leukocidin genes (SA-PVL) were initially believed to belong to the MRSA group; however, recent reports showed they also belonged to the MSSA group (MSSA-PVL). SA-PVL is common in skin and soft-tissue infections but rare in musculoskeletal infections, especially in spondylodiscitis...

Non-steroidal anti-inflammatory drugs (NSAIDs) are most extensively used over-the-counter FDA-approved analgesic medicines for treating inflammation, musculoskeletal pain, arthritis, pyrexia and menstrual cramps. Moreover, aspirin is widely used against cardiovascular complications. Owing to their non-addictive nature, NSAIDs are also commissioned as safer opioid-sparing alternatives in acute trauma and post-surgical treatments. In fact, therapeutic spectrum of NSAIDs is expanding. These "wonder-drugs" are now repurposed against lung diseases, diabetes, neurodegenerative disorders, fungal infections and most notably cancer, due to their efficacy against chemoresistance, radio-resistance and cancer stem cells...
