Abstract
Introduction Septic arthritis (SA) constitutes a pressing orthopedic emergency characterized by acute, non-traumatic joint pain. Timely diagnosis and intervention are imperative to avert complications such as chondrolysis and systemic sepsis. The etiology is predominantly hematogenous, necessitating an integrated approach involving surgical and microbiological modalities. Shoulder aspiration and microbiological analysis play pivotal roles in guiding treatment, especially when positive findings prompt more aggressive therapeutic strategies. This study aims to elucidate the nuanced clinical and epidemiological characteristics of septic arthritis in both native and prosthetic joints within a singular institutional cohort over a decade. Methods This retrospective case series analysis spanned a 10-year period, focusing on non-prosthetic shoulder joints from January 2012 to July 2021. In this timeframe, only 183 aspirations were performed and sent to the microbiology department for analysis, including cultures, microscopy, and antibiotic sensitivity tests for positive cultures. The study delved into the microbiological profile of infections, encompassing gram stain, culture positivity rates, identification of microorganisms, and antibiotic susceptibility patterns. Additionally, the incidence of primary joint infections with resistant strains, particularly methicillin-resistant Staphylococcus aureus (MRSA), was scrutinized. Statistical analysis utilized the SPSS program version 20.0 (IBM Inc., Armonk, New York), with a significance level set at 5%. The project, registered with the trust's clinical audit department (Reg #5372), adhered to the Declaration of Helsinki and good clinical practice guidelines. Data collection involved extracting non-identifiable patient modifiers from the laboratory database bank into Excel spreadsheets. Results The study included 183 patients, with 108 (59%) females and 75 (41%) males. The average age was 76.2±16.5 years. Among them, 138 (75.4%) reported pain, and 15 (8.2%) had a body temperature over 37.8°C. Lab results showed a mean white blood cell count of 11.6±4.5 and an average C-reactive protein level of 121.7±102.1. Leucocytosis (>11,000 WBC) was seen in 82 (44.8%) cases. Elevated C-reactive protein (CRP; >10 mg/dl) was found in 136 (74.3%) patients. Synovial fluid analysis revealed no crystals in 91.3% of cases. Microbial resistance analysis showed 19 strains resistant to co-trimoxazole and 11 to erythromycin. Among co-trimoxazole-resistant strains, 73.7% were Staphylococcus aureus, a statistically significant association (p<0.001). Conclusion The evolving sensitivity patterns of microbes in septic arthritis underscore the necessity to reassess empirical antibiotic therapy. Subsequent joint damage resulting from infection can result in substantial disability.

Abstract
Introduction and importance Nontyphoidal Salmonella infection can lead to gastroenteritis, enteric fever, and bacteremia. However, joint infections due to this bacterium are rare, and usually associated with immunosuppressive disorders. Case presentation A 16-year-old girl, with a recent history of acute lymphocytic leukemia (ALL) presented with bacteremia, and bilateral hip pain after COVID-19 symptoms. Clinical presentation, laboratory features and imaging showed bilateral nontyphoidal Salmonella septic arthritis. We administered antibiotics, based on antibiotics susceptibility pattern of the isolated Salmonella. Clinical discussion The case is presented because reports of bilateral hip joint infection due to nontyphoidal Salmonella are rare especially after COVID-19. When the patient presents with joint discomfort, the clinician should think infection especially in immunocompromised hosts. Conclusion It illustrates successful management of septic arthritis requires prompt clinical diagnosis, microorganism identification, administration of appropriate systemic antibiotics and hip joint surgery. Nontyphoidal Salmonella is one of the most important organisms involved in septic shock and arthritis. Acute lymphocytic leukemia (ALL) is a type of cancer that affects white blood cells (WBC). COVID-19 is a contagious disease caused by severe acute respiratory syndrome coronavirus.

Abstract
Septic arthritis is important to consider in any patient who presents with joint pain because it is a medical emergency with an 11% fatality rate. Diagnosis and treatment may improve prognosis; however, many patients do not regain full joint function. In patients with end-stage renal disease (ESRD), immune dysfunction due to uremia and chronic vascular access leads to increased risk of infection. We examined the incidence, risk factors and sequelae of septic arthritis in a cohort of hemodialysis patients. The US Renal Data System was queried for diagnoses of septic arthritis and selected sequelae using International Statistical Classification of Diseases and Related Health Problems-9 and Current Procedural Terminology-4 codes in patients who initiated hemodialysis between 2005 and 2010. Multivariable logistic regression was used to determine potential risk factors for septic arthritis and its sequelae. 7009 cases of septic arthritis were identified, an incidence of 514.8 per 100,000 persons per year. Of these patients, 2179 were diagnosed with a documented organism within 30 days prior to or 14 days after the septic arthritis diagnosis, with methicillin-resistant Staphylococcus aureus infections (57.4%) being the most common. Significant risk factors for septic arthritis included history of joint disease, immune compromise (diabetes, HIV, cirrhosis), bacteremia and urinary tract infection. One of the four sequelae examined (joint replacement, amputation, osteomyelitis, Clostridioides difficile infection) occurred in 25% of septic arthritis cases. The high incidence of septic arthritis and the potential for serious sequelae in patients with ESRD suggest that physicians treating individuals with ESRD and joint pain/inflammation should maintain a high clinical suspicion for septic arthritis.

Abstract
Background: Peri-prosthetic joint infection (PJI) is a debilitating and costly complication of joint replacement. Synovial fluid cultures are negative in up to 25% of PJI cases. The purpose of this study was to compare the clinical characteristics and outcomes of culture negative and culture positive PJI. Patients and Methods: We conducted a retrospective study including all patients aged 18 and older admitted to a single tertiary-care hospital between 1998 and 2015 diagnosed with PJI and treated with antibiotic agents and surgery. Results: One hundred ninety-six patients with PJI were identified; 48 (24.5%) were culture-negative (CN) and 148 (75.5%) were culture-positive (CP). The groups were similar in age and presence of associated comorbidities. Fever was more common among the CP patients (CN, 23.8%; CP, 38.4%; p = 0.03) as was sepsis defined by Sepsis-2 criteria (CN, 12.8%; CP, 28.7%; p = 0.03). Patients who were CP had higher synovial white blood cell (WBC) count (CN, 30,500 per milliliter; CP, 95,400 per milliliter; p < 0.01), a longer length of stay (CN, 3.8%; CP,7.9%; p = 0.02), and fewer alternative diagnoses established within one year (CN, 25.0%; CP, 2.7%; p < 0.01). Our logistic regression models also found that CP patients had an adjusted odds ratio (OR) of 2.59 for rehabilitation placement with 95% confidence interval (CI) of 1.15-5.83 and adjusted OR of 0.04 for an alternative diagnosis within one year with 95% CI, 0.009-0.22 compared with their CN counterparts. Conclusions: This study suggests that patients with CN PJI have less severe disease, better outcomes, and higher rates of alternative diagnoses within one year.

BMC Musculoskelet Disord 2020; 21:780. [PMID: 33246444 PMCID: PMC7697366 DOI: 10.1186/s12891-020-03770-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Accepted: 11/04/2020] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Septic arthritis of digits needs urgent treatment. When treatments delayed or insufficient, patients may be referred to the upper-level hospital due to uncontrolled infection. We reviewed the treatment history of referred patients and compared the microorganisms and the clinical course of both primary and referred patients as relevant studies are rare. METHODS In this retrospective review of consecutive case series, 45 patients (primary, n = 11; referred, n = 34) were treated with multiple irrigation and debridement. Cefazolin was used as empiric antibiotics, then changed according to microbiologic study. Previously used antibiotics, treatment delay, surgical history of the referred patients were reviewed. Identified microorganisms, required surgical intervention, hospital stay, radiologic outcome, functional outcomes were compared between both groups. RESULTS In the referred patients, methicillin-resistant Staphylococcus aureus (MRSA) was commonly found and cefazolin was susceptible in only 15% of the cases. Longer hospital stay, prolonged antibiotic therapy, more surgical intervention including flap surgery was required to treat the referred patients. Postoperative pain was not severe in daily activities, but the final range of motion was significantly less in the referred patients compared to the primary patients. CONCLUSIONS This study suggests that in the treatment of uncontrolled septic arthritis of the digits, antibiotic agents covering MRSA may shorten the duration of antibiotic therapy in areas of high MRSA incidence. Besides, more number of I & D including flap surgery may be required for the referred patients compared with the primary patients. These findings can help the surgeon in setting up a treatment plan or in counseling of referred patients with uncontrolled septic arthritis of the digits.

Abstract
OBJECTIVE Microorganisms can cause acute infectious arthritis, chronic infectious arthritis, or reactive inflammatory arthritis. The aim of this study is to perform a narrative review of the pathophysiology, etiology, and diagnostic features of infectious arthritis and TMJ infectious arthritis. METHODS A search of the literature was performed using Medline, Scielo, Embase, and Google Scholar databases. The terms employed for the search were "Temporomandibular Joint Disorders" and "Infectious Arthritis"; or "Septic Arthritis"; or "Bacterial, Fungal, or Viral Arthritis." Over three hundred articles were screened for eligibility. RESULTS The selected articles were utilized to perform a narrative review of the general aspects of infectious arthritis and infectious arthritis affecting the TMJ. CONCLUSION Infectious arthritis is a rare, yet very morbid, form of arthritis. Understanding general aspects of joint infections and specific features of TMJ infectious arthritis is imperative for an adequate diagnosis.

Abstract
Background: Patients with culture-negative septic arthritis patients are often treated surgically but might be successfully managed medically. We compared clinical characteristics and outcomes in patients with culture negative and culture positive native joint monoarticular septic arthritis.Methods: This retrospective study included all patients age ≥18 years admitted to a single, tertiary-care hospital between 1998 and 2015 with native joint monoarticular SA and treated with antibiotics and surgery.Results: Of 306 patients, 85 had negative and 221 had positive cultures. Mean C-reactive protein (p < .01) and mean percentage of peripheral polymorphonuclear cells (p = .01) were higher in culture-positive patients who had higher intensive care unit admission rates (16.7% vs. 4.7%, respectively, [p < .01]), longer length of hospital stay (11.4 vs. 7.1 days, respectively, [p < .01]) and higher mortality rates within 30 days (0% vs. 5.5%, respectively,[p = .02]). Of culture-negative patients, 28.6% received an alternative diagnosis within one year. Logistic regression models showed that culture positive patients had an adjusted odds ratio for length of stay of 4.5 (2.69, 7.51), intensive care unit admission of 5.76 (1.31, 25.22), discharge to rehabilitation of 4.7 (2.28, 9.71) and an alternative diagnosis within one year of 0.05 (0.02, 0.15) compared to culture negative patients.Conclusion: Patients with culture-negative native joint septic arthritis had less severe disease, better outcomes and higher rates of alternative diagnosis within one year than patients with positive cultures.

Abstract
Background Patients with a history of degenerative joint disease secondary to an acute or remote episode of septic arthritis of the native knee or hip present a unique challenge for the orthopaedic surgeon. This study describes our experience with two-stage primary arthroplasty for such patients. Methods We reviewed 42 patients with a history of septic arthritis treated with two-stage primary arthroplasty between 2008 and 2018. Patients were evaluated using modified Harris Hip Score, Knee Society Score (KSS), and KSS functional component (KSSF). Paired t-tests were used to compare changes for continuous variables within cohorts. Multivariate linear and logistic regression models were constructed to determine predictors of outcomes and complications. Results At a mean of 3.3-year follow-up, there were 14 (33.3%) complications and the infection cure rate was 95.2%. On average, patients improved in the modified Harris Hip Score (42.9 ± 11.8 vs 83.3 ± 11.1, P < .001), KSS (35.9 ± 16.9 vs 80.1 ± 16.6, P < .001), KSSF (38.0 ± 15.1 vs 71.5 ± 24.0, P < .001), knee flexion (90.9 ± 14.9 vs 100.5 ± 17.1), and hip flexion (73.8 ± 21.2 vs 102.1 ± 11.8, P < .001). Age (β: -0.78, P = .004) was independently associated with lower Harris Hip Score in the hip cohort. There were no independent predictors of the KSS or KSSF. The erythrocyte sedimentation rate (odds ratio: 1.07, P = .043) and C-reactive protein (odds ratio: 1.43, P = .018) at stage 2 were independently associated with a higher likelihood of complications at the final follow-up. Conclusion Patients with a history of native septic arthritis of the hip and knee, and secondary end-stage degenerative joint disease, showed significant postoperative improvements and a high rate of complications after two-stage primary total joint arthroplasty. Despite improvements, some patients may necessitate a third operation because of the incidence of reinfection and spacer exchange. This information should be used to counsel patients who present with this challenging clinical scenario.

Abstract
Septic arthritis (SA) is commonly associated with Staphylococcal or Streptococcal infections. Overtime, there has been a global increase in the distribution of antimicrobial resistance within both Gram-positive bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) and Gram-negative bacteria such as extended-spectrum beta-lactamase (ESBL) positive Enterobacteriacea. The aim of this study was to determine whether this change in epidemiology similarly affected the distribution of resistant pathogens causing SA. The study was conducted at the Shaare Zedek Medical Center in Jerusalem, Israel. All adult patients diagnosed with SA during 2002-2016 were included in the cohort. Antimicrobial resistance trends were examined over three periods: 2002-2009, 2010-2013, and 2014-2016. Of 85 patients with SA, mean age of patients was 66.8 (± 20.3) years, with male predominance (n = 62, 66%). Most SA cases involved native knee joints and more than 85% (n = 80) were acquired in the community. The most common isolates were S. aureus (n = 38, 45%) and beta-hemolytic streptococci (n = 13, 15%). MRSA SA was diagnosed in 8% of all SA cases (n = 7). An increasing, although non-significant trend in MRSA SA was observed during the study period (p = 0.3). Gram-negative infections were uncommon (n = 14). No ESBL-positive or carbapenem-resistant Enterobacteriacea were detected. Over a 15-year study period, no significant increase in resistant pathogens causing SA was observed. In the era of antibiotic stewardship, these results strengthen our practice of administering narrow-spectrum antimicrobials empirically for SA. However, our findings cannot be generalized to regions with higher rates of MRSA in the community.

Abstract
BACKGROUND Pediatric osteoarticular infection can cause severe morbidity. Some infectious loci may be difficult to identify clinically, and there may be more than one. There is little agreement regarding the appropriate use of preoperative magnetic resonance imaging (MRI) in this setting. After noting an unacceptably high rate of unplanned returns to the operating room for recurrent infection, clinicians at a tertiary care children's hospital noticed many patients had adjacent foci of infection on postoperative MRI. As a result, patients experienced prolonged treatment courses and multiple surgeries. An interdisciplinary team instituted practice guidelines whereby all patients with suspected osteoarticular infection underwent MRI for planned debridement during a reserved morning slot with a surgical suite on hold to proceed directly to surgery if indicated. Images were reviewed in real time to form the surgical plan. Young patients that required sedation for MRI were taken to surgery under the same anesthetic used for MRI without being awakened. The purpose of our retrospective study is to determine if implementing the practice guidelines for acute management of osteoarticular infection reduced unplanned returns to the operating room. METHODS A total of 93 patients with osteoarticular infection were included in this study. A total of 40 cases, group A, were treated before implementing practice guidelines; 53 cases, group B, were treated after implementing practice guidelines. Our primary outcomes of interest were the identification of adjacent infections prior to surgery and need for repeat surgery, either planned or unplanned. RESULTS Implementation of these guidelines reduced repeat surgery from 50% of patients to <27% (P=0.0099). Of patients requiring repeat surgery, 85% (n=17) were unplanned in group A versus 60% (n=9) in group B (P=0.0099). Adjacent infections were identified in 47.5% (n=19) of patients in group A, versus 60% (n=32) in group B. Adjacent infections were known before surgery in 32% (n=6) of patients in group A versus 72% (n=23) in group B. There were no statistically significant differences in initial patient characteristics or sites of infection. CONCLUSIONS Implementing these guidelines reduced the need for repeat surgery in this population. It is difficult to predict with sufficient accuracy which patients need preoperative MRI. While resource intensive, preoperative MRI appears to offer substantial benefit in preoperative planning.

Predicting Periarticular Infection in Children With Septic Arthritis of the Hip: Regionally Derived Criteria May Not Apply to All Populations. J Pediatr Orthop 2019; 39:268-274.

Abstract
BACKGROUND The management of septic arthritis of the hip in children can be complicated by the presence of additional coexisting periarticular infections (PAIs). Criteria predicting the presence of PAI have recently been proposed by Rosenfeld and colleagues with the goal of using magnetic resonance imaging (MRI) efficiently in the workup of septic arthritis. The purpose of this study was to determine the applicability of recently published predictive criteria for PAI (developed in the Southwestern United States using a variety of joints) to septic arthritis of the hip treated at a large Northeastern tertiary care center. METHODS We studied patients treated for septic arthritis of the hip with irrigation and debridement in a large Northeastern tertiary care center over a 10-year period. Laboratory and clinical variables related to presentation, treatment, and outcome were collected. Subjects with and without a perioperative MRI were compared with published criteria by Rosenfeld and colleagues. RESULTS Fifty-one subjects (53 hips) were identified with a mean age of 7.0 years (range, 1.2 to 19.3 y) and mean follow-up was 16 months (range, 2 to 85 mo). MRIs were obtained in 20 subjects (43%). Coexisting osteomyelitis was revealed in 7/20 of these studies (35% of MRIs); 4 of which showed coexisting intramuscular abscesses. Within our MRI cohort, the Rosenfeld criteria were found to have a sensitivity of 86%, a specificity of 54%, and a false-positive rate of 50% for the hip (compared with originally reported sensitivity of 90%, specificity of 67%, and false-positive rate of 33%). Overall, advanced imaging changed management in 5/51 patients (9%) by influencing the need for further treatment, whereas the remainder underwent isolated treatment of the septic hip joint with no adverse outcomes. One patient in the MRI cohort (without PAI) developed osteonecrosis of the femoral head. CONCLUSIONS We found lower sensitivity and specificity and higher false-positive rates for the Rosenfeld criteria in the hip for our geographically distinct population. Using the Rosenfeld criteria, MRIs would have been ordered unnecessarily in half of our series. Because of potential differences in regional microbiology and anatomic-specific factors, general predictive criteria for coexisting PAI based a single geographic region may be less generalizable to cases of hip sepsis in other geographic areas such as the Northeastern United States. LEVEL OF EVIDENCE Level 4-retrospective cohort study.

Abstract
INTRODUCTION Streptococcus agalactiae (Group B Streptococcus, GBS) is an uncommon cause of septic arthritis in the adult population. In recent years, there has been an increase in the incidence of GBS septic arthritis. This study aims to compare the clinical presentation, investigations, microbiology and outcome of management in patients with GBS and non-GBS septic arthritis. METHODS Retrospective review of hospital surgical records was done to identify all patients treated surgically at our institution from January 2011 to January 2016 for primary septic arthritis. Patients were categorised into two groups: those with culture-proven GBS septic arthritis and those with causative pathogens that were not GBS. Patients who were medically unfit for surgical intervention as well as those who declined interventional procedures were excluded from the study. RESULTS A total of 83 patients were included in the study: 62 (74.7%) had non-GBS septic arthritis and 21 (25.3%) had GBS septic arthritis. Patients with GBS septic arthritis were more likely to have polyarticular involvement (p < 0.001) and involvement of less common sites such as the elbow joint. They were also more likely to have elevated inflammatory markers (C-reactive protein > 150 mg/L; p = 0.017) and positive blood cultures (p = 0.02), and were typically healthy adults with no medical comorbidities (p = 0.012). CONCLUSION Patients with GBS septic arthritis were more likely to present with polyarticular involvement, positive blood cultures and higher levels of C-reactive protein on admission, and tended to be healthier individuals with no medical comorbidities.

Gram-negative multi-drug resistant bacteria influence survival to discharge for horses with septic synovial structures: 206 Cases (2010-2015). Vet Microbiol 2018; 226:64-73. [PMID: 30389045 DOI: 10.1016/j.vetmic.2018.10.009] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2018] [Revised: 09/26/2018] [Accepted: 10/10/2018] [Indexed: 11/29/2022]
Abstract
Bacterial colonization of synovial structures can cause infections that are difficult to treat. Systemic and local antimicrobials and repeated joint lavages are the mainstays of therapy. However, despite aggressive treatments, infection may persist, leading to significant tissue damage or death of the patient. In order to investigate the impact of bacterial culture and antimicrobial resistance on survival to discharge, we reviewed medical records of horses admitted to the University of Pennsylvania's large animal teaching hospital from 2010-2015. Two-hundred and six cases with a definitive diagnosis of septic synovitis and a synovial fluid sample submitted for microbiological culture were included in the study. Of these horses, 48% were culture negative and 52% were positive for any bacterial growth, of which 66% were gram-positive and 28% were gram-negative aerobic organisms with 4% anaerobic and 2% fungal organisms. Overall survival to discharge from hospital was 86%. Horses that had negative growth on culture were more likely to survive until discharge (p < 0.02). Multivariable analyses revealed that the likelihood of euthanasia was significantly associated with identification of coagulase positive Staphylococcus spp. (OR 7.66, 5.46-10.74, p < 0.0001), β-hemolytic Streptococcus spp. (OR 5.18, 3.56-7.55, p < 0.0001), Enterococcus spp. (OR 18.38, 11.45-29.52, p = 0.002), Enterobacteriaceae (OR 31.37, 22.28-44.17, p < 0.0001), Pseudomonas aeruginosa (OR 9.31, 5.30-16.34, p = 0.0004) or other gram-negative species (OR 3.51, 2.07-5.94, p = 0.001). Multi-drug resistance and gram-negative bacteria species were associated with significantly decreased survival rates (OR 119.24, 70.57-201.46, p < 0.0001). In conclusion, prognosis for survival to discharge was poor for horses that were infected with gram-negative organisms, particularly those with MDR phenotypes.

Abstract
Acute septic arthritis (ASA) caused by Staphylococcus aureus can lead to fulminant arthritis and cause permanent joint destruction. In particular, infection caused by methicillin-resistant Staphylococcus aureus (MRSA) becomes intractable and severe owing to limitation of therapeutic drugs. Here, we report the case of a young patient with ASA without any record of overseas travel, who was infected by the Panton-Valentine leukocidin-positive Bengal-Bay clone, which is a predominant community-acquired MRSA in India.

Abstract
The purpose of this study was to determine the prognostic factors related to the outcome of lavage surgery in patients with septic arthritis of the knee. A total of 55 patients with acute septic arthritis who underwent arthroscopic lavage were enrolled in the study. Host factors, including age, medical comorbidities, and medication use, were evaluated according to the Musculoskeletal Infection Society staging system, and patients were then stratified into 3 types: type A, no compromising factors; type B, 1 to 2 compromising factors; and type C, more than 2 compromising factors. Routes of infection were classified. Causative organisms were classified as gram positive, gram negative, mixed, or culture negative. Multivariable analysis confirmed that type C hosts showed more than 16 times the risk for failure of a single arthroscopic lavage than type A hosts. Type B hosts showed no significant differences from either type A or type C hosts. Patients with gram-positive cultures had more than 13 times the risk for failure than patients who were culture negative. Patients with gram-negative and mixed cultures showed no significant differences from the other groups. The sex of the patient and the route of infection were not related to the success of a single arthroscopic lavage surgery. Patients in poor health (ie, very medically ill) and with gram-positive cultures should be counselled regarding potential failure after a single arthroscopic debridement procedure.

Abstract
Septic arthritis is a rheumatologic emergency that may lead to disability or death. Prompt evacuation of the joint, either by arthrocentesis at the bedside, open or arthroscopic drainage in the operating room, or imaging-guided drainage in the radiology suite, is mandatory. Methicillin-resistant Staphylococcus aureus (MRSA) has become a major cause of septic arthritis in the United States. MRSA joint infection seems to be associated with worse outcomes. Antibiotic courses of 3 to 4 weeks in duration are usually adequate for uncomplicated bacterial arthritis. Treatment duration should be extended to 6 weeks if there is imaging evidence of accompanying osteomyelitis.

Abstract
A 58-year-old male presented with native joint septic arthritis of the hip and osteomyelitis. After treatment with an articulating antibiotic spacer, he developed acute renal failure requiring dialysis. He continued to have elevated serum tobramycin levels exclusively from the antibiotic spacer elution as no intravenous tobramycin was used. Subsequent explantation was required to correct his renal failure. Although renal failure after antibiotic impregnated cement placement is rare, the risk of this potential complication should be considered preoperatively and in the postoperative management of these patients.

Abstract
Background: The objective of this study was to determine prognostic factors affecting the clinical outcome of septic arthritis of the shoulder. Methods: We retrospectively reviewed 34 shoulders from 32 patients, two of which had bilateral involvement. Arthroscopic (22 shoulders) or open surgery (12 shoulders) was performed by a single surgeon. The mean follow-up period was 32.4 ± 17.0 months. Clinical outcomes according to the University of California at Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and Subjective Shoulder Value (SSV) were assessed at the final follow-up period. Various factors were included for statistical analysis. Results: The mean UCLA, ASES scores, and SSV were 28.9 ± 7.2, 81.3 ± 21.0, 79.7 ± 2.5%, respectively. Positive culture was observed in only 13 shoulders (38.2%) and the most common organism was Staphylococcus aureus (seven shoulders). Five shoulders (14.7%) required two or three operations. Age and comorbidity were negatively correlated with the UCLA, ASES score, and/or SSV (p < 0.05). There was no correlation between clinical outcome and various parameters, including gender, location of lesion, history of previous steroid injection, interval between onset of symptoms and surgical intervention, bacterial organisms, operative method, and presence of rotator cuff tear and reoperation (p > 0.05). Conclusions: Both arthroscopic and open surgery for septic shoulders showed satisfactory clinical outcomes. Old age and comorbidity were poor prognostic factors of clinical outcomes after treatment.

Abstract
Is neutrophil-to-lymphocyte ratio high in patients with septic arthritis? Septic arthritis may lead to higher rates of morbidity or even mortality if not diagnosed on time. This study was planned to answer the question that “Could neutrophil-to-lymphocyte ratio be utilized to help to diagnose septic arthritis?” The cohort of the study consisted of 39 patients diagnosed with septic arthritis. After ruling out the patients who did not meet the research’s inclusion criteria, the data of 26 patients were evaluated. The control group was collected from healthy volunteers who were admitted to the internal medicine outpatient clinic for a routine medical checkup at the same period (n = 26). Complete blood count (CBC) parameters, C-reactive protein, erythrocyte sedimentation rate, and neutrophil-to-lymphocyte ratios of the septic arthritis and control groups were compared statistically. In comparison, neutrophil-to-lymphocyte ratios of the septic arthritis group were significantly higher than the control group. In conclusion, neutrophil-to-lymphocyte ratio can be utilized in the emergency department or in outpatient clinics to support the diagnosis of septic arthritis.

Abstract
Rheumatological conditions can sometimes present as emergencies. These can occur due to the disease process or infection; contrary to what many people think, rheumatologic emergencies like a pain, rheumatic crisis, or attack gout do not compromise the patient's life. This article mentioned only true emergencies: catastrophic antiphospholipid syndrome (cAPS), kidney-lung syndrome, central nervous system (CNS) vasculitis, anti-Ro syndrome (neonatal lupus), and macrophage activation syndrome (MAS). The management of above emergencies includes critical care, immunosuppression when indicated, and use of a diagnostic flowchart as well as fast laboratory profile for making decisions. Anticoagulants have to be used in the management of antiphospholipid syndrome. A good understanding of these conditions is of paramount importance for proper management.

Abstract
INTRODUCTION Septic arthritis and osteomyelitis can both independently cause substantial morbidity. With concomitant septic arthritis and osteomyelitis, the septic arthritis may be treated without knowledge of the adjacent osteomyelitis resulting in delayed treatment. This study aims to identify factors that may help to diagnosis concurrent infections (CI) earlier. METHODS A retrospective chart review of 200 patients with septic arthritis was performed. Patients with CI were compared with patients with septic arthritis alone using tests determined by the nature of the variable being analyzed (the χ test, the Fisher exact test, the Cochran-Armitage trend test, and the Kruskal-Wallis test.). RESULTS Two hundred patients were eligible and analyzed, of which 43 (21.5%) had CI. On the basis of age, CI were most common in newborns and adolescents (P<0.0001). On the basis of location, 72% of shoulder infections (P<0.0001) were concurrent, whereas <50% of elbows, hips, knees, and ankle were CI. The most common infective organism was methicillin-sensitive Staphylococcus aureus (P<0.0001). CI were significantly associated with increased median (6) days of clinical symptoms before presentation (P<0.0001), increased duration of median (6) days of hospital stay (P<0.0001), increased number of operative procedures (P=0.005), and increased need for ICU admission (P=0.024). CONCLUSIONS Utilizing advanced imaging (CT scan, bone scan, and/or MRI) in patients with septic arthritis who are younger than 4 months of age, between ages 13 and 20 years, with septic arthritis involving the shoulder, and with symptoms for more than 6 days may shorten hospital stays, decrease the number of operative procedures required, and possibly limit infection-related sequelae by identifying CI earlier.

Abstract
HYPOTHESIS Septic arthritis of the elbow is a serious orthopedic concern associated with high morbidity and mortality rates, traditionally treated with open exposure of the elbow joint. This study was performed to describe the outcome of arthroscopic treatment of septic elbow arthritis. METHODS From May 2000 through January 2008, 12 patients with septic elbow arthritis were treated arthroscopically at the Mayo Clinic, Rochester, Minnesota, a large medical center. We reviewed the patients' medical records concerning variables such as history and clinical findings, previous elbow history, surgical procedure, cultured organism, and follow-up. Using the Oxford Elbow Score and the Mayo Elbow Score, we examined current level of pain, function, and social-psychological aspects. Six patients died before initiation of this study and were therefore only studied retrospectively. RESULTS Septic elbow arthritis without pre-existing elbow problems shows excellent outcomes after arthroscopic treatment, with scores for absence of pain, function, social-psychological well-being, and range of motion of 97.9%, 100%, 95.8%, and 100%, respectively. When elbows were treated arthroscopically within 2 days after the onset of clinical symptoms suggesting bacterial elbow arthritis, maximum scores of 100% were noted for all aspects. Positive elbow history before infection and reoperation were associated with poor outcome scores, with 62.5%, 85.4%, and 50% for absence of pain, function, and social-psychological well-being, respectively. CONCLUSION Septic elbow arthritis occurs often in the debilitated, immunocompromised patient. Arthroscopic intervention is a reasonable alternative to open treatment. In this small series, the acutely septic elbow was successfully treated in the majority of patients, although the overall patient mortality rate remains high.

Abstract
The causes of knee pain in patients with cancer with are different from those without cancer, and the purpose of this study was to evaluate these differences. Thirty-six patients with cancer who had knee pain who had undergone 1 or more modalities of treatment, including chemotherapy, radiotherapy, and bone marrow transplant, for a primary diagnosis of cancer were compared with a cohort of 40 patients without cancer who had knee pain. All patients were evaluated clinically and underwent radiographic examination, and some underwent computed tomography or magnetic resonance imaging examination. Among patients with a primary diagnosis of cancer, the most common diagnosis was lymphoma (n=10), and the most common causes of knee pain were avascular necrosis of bone, osteoarthritis, insufficiency fractures, and septic arthritis. In 5 patients, the classical signs of a septic knee were not present. Other causes of knee pain included meniscus tear and anterior cruciate ligament rupture with instability. The most common diagnosis in patients without cancer was osteoarthritis of the knee. No patient without cancer was diagnosed with avascular necrosis, metastatic lesion, or insufficiency fracture. Two patients without cancer were diagnosed with septic arthritis of the knee. This study showed that the causes of knee pain in patients with cancer are different from those without cancer. Septic arthritis may present without the classical clinical signs in patients with cancer, and a high index of suspicion should be maintained for it.

Abstract
OBJECTIVES Silver carbenes may represent novel, broad-spectrum antimicrobial agents that have low toxicity while providing varying chemistry for targeted applications. Here, the bactericidal activity of four silver carbene complexes (SCCs) with different formulations, including nanoparticles (NPs) and micelles, was tested against a panel of clinical strains of bacteria and fungi that are the causative agents of many skin and soft tissue, respiratory, wound, blood, and nosocomial infections. METHODS MIC, MBC and multidose experiments were conducted against a broad range of bacteria and fungi. Time-release and cytotoxicity studies of the compounds were also carried out. Free SCCs and SCC NPs were tested against a panel of medically important pathogens, including methicillin-resistant Staphylococcus aureus (MRSA), multidrug-resistant Acinetobacter baumannii (MRAB), Pseudomonas aeruginosa, Burkholderia cepacia and Klebsiella pneumoniae. RESULTS All four SCCs demonstrated strong efficacy in concentration ranges of 0.5-90 mg/L. Clinical bacterial isolates with high inherent resistance to purified compounds were more effectively treated either with an NP formulation of these compounds or by repeated dosing. Overall, the compounds were active against highly resistant bacterial strains, such as MRSA and MRAB, and were active against the biodefence pathogens Bacillus anthracis and Yersinia pestis. All of the medically important bacterial strains tested play a role in many different infectious diseases. CONCLUSIONS The four SCCs described here, including their development as NP therapies, show great promise for treating a wide variety of bacterial and fungal pathogens that are not easily killed by routine antimicrobial agents.

Abstract
Hip pain is a common presenting complaint in the pediatric emergency department, which can be attributed to many possible causes. It may be due to a benign "growing pain" or a potentially serious illness requiring urgent evaluation. At times, hip pain can be a manifestation of an underlying appendicitis in a child; thus, it can be confused with many other conditions. Children can be at particular risk for misdiagnosis or delayed diagnosis of appendicitis as it often can have an uncommon presentation with atypical signs and symptoms. Early identification, however, is important to prevent potential complications of delaying the diagnosis. We present a case that illustrates an atypical presentation of acute appendicitis. This report also highlights the diagnostic dilemma encountered during the evaluation of hip pain in children.

Abstract
One of the main causes of neuropathic osteoarthropathy of the shoulder is cervical syringomyelia. Chronic pain and swelling of the shoulder are the most frequent manifestations, but it occasionally can develop rapid osteoarticular destructive lesions (in less than six weeks), which raise the diagnostic possibility of septic arthritis and some tumours We present the report of two men with septic arthritis of the shoulder associated with neuropathic arthropathy secondary to syringomyelia. Both patients presented with sudden shoulder pain exacerbated by either passive or active joint movements, malaise and fever. The first patient, a 39-year-old man, suffered left shoulder arthritis due to Staphylococcus aureus. The second patient, a 59-year-old man presented with right shoulder arthritis caused by to Staphylococcus epidermidis. The last microorganism also was isolated in three blood cultures. Infection should certainly be considered as a possible complication of the natural history of the neuropathic shoulder.

Abstract
Over recent years, the incidence of infection caused by antibiotic-resistant Acinetobacter baumannii (a conditional pathogenic bacterium) has showed an increasing trend in such hospital departments as ICUs. Infections caused by antibiotic-resistant A. baumannii have drawn much attention from the medical professionals because it is difficult to manage such infections, and because the mortality related to such infections is high. To date, no cure of gouty arthritis and septic arthritis meanwhile complicated by antibiotic-resistant A. baumannii infection has been reported. We cured such a patient of intractable knee infection caused by A. baumannii resistant to all conventional antibiotics including imipenem by taking comprehensive measures including surgery, and infection did not recur during the 14-month follow-up.

Abstract
Septic arthritis is an infection of the joint space that requires prompt recognition by physicians. In children, the diagnosis of septic arthritis can often be challenging and delayed diagnosis can produce long-term morbidity. Posttraumatic septic arthritis is rarely reported and can be an equally challenging diagnosis. We present a case of a fully immunized 20-month-old boy with Streptococcus pneumoniae posttraumatic septic arthritis without evidence of an open fracture.

Abstract
Septic arthritis is frequently observed especially in immune-compromised or chronically diseased patients and leads to functional impairment due to tissue destruction. Recently, production of antimicrobial peptides (AMP) was observed in articular cartilage after exposure to bacteria. This report examines the role of synoviocyte-derived AMPs in innate defense mechanisms of articular joints. Samples of healthy, low-grade synovialitis and septic synovial membranes were assessed for the expression of human beta-defensin-2 (HBD-2) and Toll-like receptor-2 and -4 (TLR) by immunohistochemistry and enzyme-linked immunosorbent assay (ELISA). A stable synoviocyte line (K4IM) was used for in vitro experiments and assayed for endogenous HBD-2 and TLR production after exposure to inflammatory cytokines or bacterial supernatants by reverse transcription polymerase chain reaction (RT-PCR), real-time RT-PCR, Western blot, ELISA, and dual luciferase assay. Healthy human synovial membranes and cultured synoviocytes are able to produce HBD-2 and TLR-1-5 at basal expression levels. Samples of bacteria-colonized synovial membranes produce higher levels of HBD-2 when compared with samples of healthy tissues. K4IM synoviocytes exposed to Staphylococcus aureus, Pseudomonas aeruginosa, or proinflammatory cytokines demonstrated a clear HBD-2 transcription and protein induction. TLR-2 and -4 are known to have a critical role in the recognition of gram-positive and gram-negative bacteria in epithelia and are induced in mesenchymal synoviocytes after bacterial exposure on transcription and on protein level. This report demonstrates an unappreciated role of synovial membranes: samples of septic synovial membranes and cultured synoviocytes exposed to bacteria produce increased amounts of the AMP HBD-2 and the bacteria recognition receptors TLR-2 and -4. The induction of anti-inflammatory pathways in infected synoviocytes suggests involvement in intra-articular defense mechanisms.

Abstract
Staphylococcus aureus is a common human pathogen. S aureus infections most commonly clinically manifest as skin infections. There has been much interest in S aureus infections in the community over the past decade because of the rise of community-associated methicillin-resistant S aureus (CA-MRSA) infections, which have emerged globally over a relatively short period of time. In contrast to health care-associated methicillin resistant S aureus (HA-MRSA), circulating strains of CA-MRSA have characteristic pathogenesis, strain characteristics, epidemiology, and clinical manifestations that are distinct from HA-MRSA. In fact, CA-MRSA probably behaves more like community-associated methicillin-sensitive S aureus (MSSA). This article reviews current knowledge of the epidemiology and clinical manifestations of community-associated S aureus and CA-MRSA infections.

Abstract
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has emerged over the last decade across the United States and the world, becoming a major pathogen in many types of community-acquired infections. Although most commonly associated with minor skin and soft tissue infections, such as furuncles, CA-MRSA also can cause necrotizing fasciitis, pyomyositis, osteoarticular infections, and community-acquired pneumonia. This article discusses the epidemiology, diagnosis, and management of these infections from the perspective of the emergency physician.

Abstract
Septic arthritis (SA) is a rheumatologic emergency associated with significant morbidity and mortality. Delayed or inadequate treatment of SA can lead to irreversible joint destruction and disability. Current methods of diagnosing SA rely on synovial fluid analysis and culture which are known to be imprecise and time-consuming. We report a novel adaptation of a probe-based real-time PCR assay targeting the 16S rRNA gene for early and accurate diagnosis of bacterial SA. The assay algorithm consists of initial broad-range eubacterial detection, followed by Gram typing and species characterization of the pathogen. The platform demonstrated a high analytical sensitivity with a limit of detection of 10(1) CFU/ml with a panel of SA-related organisms. Gram typing and pathogen-specific probes correctly identified their respective targets in a mock test panel of 36 common clinically relevant pathogens. One hundred twenty-one clinical synovial fluid samples from patients presenting with suspected acute SA were tested. The sensitivity and specificity of the assay were 95% and 97%, respectively, versus synovial fluid culture results. Gram-typing probes correctly identified 100% of eubacterial positive samples as to gram-positive or gram-negative status, and pathogen-specific probes correctly identified the etiologic agent in 16/20 eubacterial positive samples. The total assay time from sample collection to result is 3 h. We have demonstrated that a real-time broad-based PCR assay has high analytical and clinical performance with an improved time to detection versus culture for SA. This assay may be a useful diagnostic adjunct for clinicians, particularly those practicing in the acute care setting where rapid pathogen detection and identification would assist in disposition and treatment decisions.

Abstract
Background: Septic arthritis is considered a rheumatologic emergency that can lead lo joint destruction and tong-term impairment of joint function, Daptomycin is bactericidal in vitro against Staphylococcus aureus, the primary pathogen associated with septic arthritis. Objective: To describe the use of daptomycin in patients with septic arthritis, Methods: Data were collected as part of the Cubicin Outcomes Registry and Experience (CORE) program, a retrospective, observational, multicenter study, to describe the clinical use of daptomycin. Efficacy at the end of daptomycin therapy was determined by each center's investigator(s) as cure, improved, failure, or nonevaluable. Patients who had a diagnosis of septic arthritis, excluding concomitant osteomyelitis, as well as a positive culture by needle aspirate or deep tissue biopsy, were selected from the combined 2005 and 2006 CORE database. Results: Twenty-two patients were included in this analysis. S. aureus was the most common pathogen isolated, with the majority resistant lo methicillin. All patients received an antibiotic prior to daptomycin; in 7 patients, at least one of the prior antibiotics was continued with daptomycin. Almost two-thirds of patients received an antibiotic with daptomycin; rifampin was the most common. The median final dose and duration of daptomycin therapy were S mg/kg (range 3–6.3) and 22 days (range 3–52), respectively. Eighty-two percent of patients received daptomycin while admitted to a hospital; however, 68% received at least part ol their daptomycin therapy as an outpatient. The outcomes of cure or improved were reported in 41% and 50% of the patients, respectively. Two adverse events were reported; neither was considered to be related to daptomycin. Conclusions: Daptomycin appeared to be effective when used as part of a treatment regimen for septic arthritis. These results require verification via a prospective clinical trial.

Abstract
The innate immune system uses a wide variety of pattern recognition receptors including TLRs, scavenger receptors, and lectins to identify potential pathogens. A carefully regulated balance between activation and inhibition must be kept to avoid detrimental and inappropriate inflammatory responses. In this study, we identify murine-paired Ig-like receptor (PIR)-B, and its human orthologs Ig-like transcript 2 and Ig-like transcript 5 as novel receptors for Staphylococcus aureus. PIR-B contains four ITIM motifs and is thought to be an inhibitory receptor. Expression of these receptors enables NIH3T3 cells to bind S. aureus. In mouse bone marrow-derived macrophages, masking of PIR-B by anti-PIR mAb or genetic deletion of PIR-B shows significantly impaired recognition of S. aureus and enhanced TLR-mediated inflammatory responses to the bacteria. These data suggest a novel mechanism for innate immune regulation by paired Ig-like receptor family members.

Abstract
Septic arthritis of the shoulder, elbow, or wrist is not commonly described in the literature. We evaluated the micro- biology of these infections and the diagnostic role of joint aspirate findings. This retrospective study includes 52 patients, diagnosed from 1994 to 2004, with septic arthritis of the shoulder (n = 17), elbow (n = 23), or wrist (n = 12). The mean age was 44.3 years, and 54% of patients (28/52) had comorbidities. The prevalence of Staphylococcus aureus was 76%. Ninety-six percent of aspirates with positive cultures had a polymorphonuclear differential count greater than 85% of the total aspirate white blood cell count. Staphylococcus aureus is the most prevalent organism. A high index of suspicion for septic arthritis is necessary for all patients with upper extremity joint complaints, irrespective of age and medical status. The joint aspirate differential white blood cell count may be helpful in the diagnosis.

Abstract
We asked whether adjacent osteomyelitis with acute septic knee arthritis explained a lack of response to initial management, and whether patient comorbidities predisposed to the nonresponsiveness. From 147 adult patients (151 knees) with septic arthritis, we identified 29 patients (33 knees) who had persistence or recurrence of symptoms after surgical drainage. Adjacent osteomyelitis was present in 31 (94%) of the 33 knees (27 of 29 patients) with poor response to treatment. Patients with adjacent osteomyelitis had more comorbid conditions (23 of 27 patients, 85%) than patients without osteomyelitis (64 of 120, 53%). The most common comorbid conditions in patients with adjacent osteomyelitis were diabetes mellitus (10 patients, 37%) and intravenous drug use (eight patients, 30%). We identified Staphylococcus aureus in 19 of 31 knees (61%) with osteomyelitis, eight (26% of total cases) of which were methicillin-resistant. Persistence of clinical signs of infection after surgical management of septic knee arthritis in adults should raise the suspicion of adjacent osteomyelitis, especially in patients with comorbid conditions. Additional imaging studies may be necessary to evaluate the distal femur and proximal tibia.
