    Before 1983, septic arthritis was rare in patients with hemophilia. With the advent of human immunodeficiency virus infection in the hemophilia population, many centers noted an increasing incidence of patients with septic arthritis. Fifteen septic joints in 10 patients with severe hemophilia were documented. Eight patients were human immunodeficiency virus positive, 1 was human immunodeficiency virus negative, and 1 was not tested. The diagnosis was delayed in 5 patients because the symptoms are similar to an acute hemarthrosis. An elevated temperature was common. The white blood cell count was elevated in only 1/3 of the infections, being modified by human immunodeficiency virus infection. Associated risk factors included infected angioaccess catheters (2), pneumonia (2), and generalized sepsis (1). All but 1 joint responded to appropriate antibiotics and either repeated aspiration or arthrotomy. However, 6 patients died of acquired immunodeficiency syndrome from 2 to 109 months after infection. Three patients are alive 29, 86, and 96 months, respectively, after infection.

    Acute septic arthritis is rare. It is associated with poor prognosis in terms of mortality and morbidity. We report the case of a 61-year old patient with spontaneous Proteus mirabilis septic arthritis. He suffered from complicated diabetes associated with positive blood cultures and synovial fluid cultures. Patient's evolution was favorable thanks to early diagnosis and initiation of adequate antibiotic therapy. Proteus mirabilis septic arthritis is rare. On that basis we conducted a literature review of cases of Proteus mirabilis pyogenic arthritis to highlight the risk factors, pathogenesis, treatment and evolution of these diseases. Diagnosis is commonly based on microbiological analysis, early articular puncture biopsy is performed before the initiation of antibiotic treatment, direct examination, culture and antibiogram which are useful as guidance for antibiotic therapy. Septic arthritis is a diagnostic and therapeutic emergency; early management of this disease allows total healing without after-effects.

    Synovial fluid, ultrasound, and radiographic imaging are common diagnostic tools for septic arthritis. Mycoplasma septic arthritis is suspected in calves with clinical signs of otitis and pneumonia. Commonly affected joints are carpus, stifle, and tarsus. Treatment strategy must include long-term antibiotics, anti-inflammatories, and joint lavage. Knowledge of communication and boundaries for commonly affected joints is essential to perform joint lavage and arthrotomy.

  6. Acute septic arthritis.

    2002-10-01

    Acute septic arthritis may develop as a result of hematogenous seeding, direct introduction, or extension from a contiguous focus of infection. The pathogenesis of acute septic arthritis is multifactorial and depends on the interaction of the host immune response and the adherence factors, toxins, and immunoavoidance strategies of the invading pathogen. Neisseria gonorrhoeae and Staphylococcus aureus are used in discussing the host-pathogen interaction in the pathogenesis of acute septic arthritis. While diagnosis rests on isolation of the bacterial species from synovial fluid samples, patient history, clinical presentation, laboratory findings, and imaging studies are also important. Acute nongonococcal septic arthritis is a medical emergency that can lead to significant morbidity and mortality. Therefore, prompt recognition, rapid and aggressive antimicrobial therapy, and surgical treatment are critical to ensuring a good prognosis. Even with prompt diagnosis and treatment, high mortality and morbidity rates still occur. In contrast, gonococcal arthritis is often successfully treated with antimicrobial therapy alone and demonstrates a very low rate of complications and an excellent prognosis for full return of normal joint function. In the case of prosthetic joint infections, the hardware must be eventually removed by a two-stage revision in order to cure the infection.

  7. Septic arthritis after ureteroneocystostomy.

    1979-04-01

    Acute infectious arthritis is an uncommon disease that is most commonly caused by Neisseria gonorrhoeae or gram-positive cocci. Gram-negative bacteria are an infrequent and highly virulent cause of septic arthritis and most commonly enter the circulation through the urinary tract, as in this case after ureteroneocystostomy. The resulting arthritis carries a mortality of 25% and a morbidity of 80%. Early recognition and treatment with appropriate antibiotics and mechanical drainage is imperative. Needle drainage of the affected joint has been shown superior to open surgical drainage.

  8. Neonatal septic arthritis.

    PubMed

    1983-11-01

    To assess and correlate the microbiology of neonatal septic arthritis with the clinical presentation, we reviewed the records of nine infants with neonatal septic arthritis (NSA) diagnosed at Edmonton hospitals between 1964 and 1981, and evaluated 92 other cases reported in the English literature since 1960. Our analysis revealed that the microbiology of NSA seemed to be dependent on whether it was hospital or community acquired. In the hospital-acquired cases, staphylococci were the predominant isolates (62%), followed by Candida species (17%) and gram-negative enteric bacilli (15%). Community-acquired arthritis was caused most often by streptococci (52%), followed by staphylococci (26%) and gonococci (17%). Since 1970, the relative infrequency of staphylococcal (5%) in favor of streptococcal (75%) isolates in community-acquired NSA is even more pronounced.

    1996-09-01

    Neonatal septic arthritis has always been considered as separate from its counterpart in older children. The condition is uncommon but serious. Affected neonates usually survive, but with permanent skeletal deformities. Ten cases of neonatal septic arthritis were diagnosed between January 1989 and December 1993 in the neonatal intensive care units of two referral hospitals in the state of Kelantan, Malaysia. All except one neonate was born prematurely. The mean age of presentation was 15.6 days. Joint swelling (10/10), increased warmth (7/10) and erythema of the overlying skin (7/10) were the common presenting signs. Vague constitutional symptoms preceded the definitive signs of septic arthritis in all cases. The total white cell counts were raised with shift to the left. The knee (60%) was not commonly affected, followed by the hip (13%) and ankle (13%). Three neonates had multiple joint involvement. Coexistence of arthritis with osteomyelitis was observed in seven neonates. The commonest organism isolated was methicillin resistant Staphylococcus aureus (9/10). Needle aspiration was performed in nine neonates and one had incision with drainage. Follow up data was available for five neonates and two of these had skeletal morbidity. Early diagnosis by frequent examination of the joints, prompt treatment and control of nosocomial infection are important for management.

    2015-03-01

    Acromioclavicular (AC) and sternoclavicular (SC) septic arthritis with contiguous pyomyositis are rare, especially in immunocompetent individuals. We report a case of septic AC joint with pyomyositis of the deltoid and supraspinatus muscles and a separate case with septic SC joint with pyomysitis of the sternocleidomastoid muscle. Both patients had similar presentations of infections with Staphylococcus aureus and were successfully treated with surgical incision and drainage followed by prolonged antibiotic therapy.

    2015-11-20

    Bilateral septic arthritis of the shoulder is uncommon in the immunocompetent patient with no previous risk factors for joint infection, and is thus easily missed. Septic arthritis is associated with significant rates of morbidity and mortality. Early diagnosis and management is the key to a favourable outcome; septic arthritis should be considered as a differential diagnosis in the unwell patient presenting with shoulder pain and reduced range of joint movement. We present a case of a 47-year-old previously fit and well man with bilateral shoulder septic arthritis. We will also review the current literature on management and long-term outcomes of patients with septic arthritis of the glenohumeral joint.

  12. Septic Arthritis of Native Joints.

    PubMed

    Ross, John J

    2017-03-30

    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.

    We report on the first case of documented Helicobacter cinaedi septic arthritis in an immunocompetent heterosexual young man. The patient presented no identified risk factor except for contact with animals that have been incriminated as a possible source of infection, particularly for these patients. Despite prolonged bacteremia, the response to long-term therapy with ciprofloxacin and rifampin was excellent.

    2014-06-01

    Management of fungal osteomyelitis and fungal septic arthritis is challenging, especially in the setting of immunodeficiency and conditions that require immunosuppression. Because fungal osteomyelitis and fungal septic arthritis are rare conditions, study of their pathophysiology and treatment has been limited. In the literature, evidence-based treatment is lacking and, historically, outcomes have been poor. The most common offending organisms are Candida and Aspergillus, which are widely distributed in humans and soil. However, some fungal pathogens, such as Histoplasma, Blastomyces, Coccidioides, Cryptococcus, and Sporothrix, have more focal areas of endemicity. Fungal bone and joint infections result from direct inoculation, contiguous infection spread, or hematogenous seeding of organisms. These infections may be difficult to diagnose and eradicate, especially in the setting of total joint arthroplasty. Although there is no clear consensus on treatment, guidelines are available for management of many of these pathogens.

    Septic arthritis has long been considered an orthopedic emergency. Historically, Neisseria gonorrhoeae and Staphylococcus aureus have been the most common causes of septic arthritis worldwide but in the modern era of biological therapy and extensive use of prosthetic joint replacements, the spectrum of microbiological causes of septic arthritis has widened considerably. There are also new approaches to diagnosis but therapy remains a challenge, with a need for careful consideration of a combined medical and surgical approach in most cases.

    The cases are reported of two patients with chronic Lyme arthritis resistant to the recommended antibiotic regimens who were cured by long term treatment with benzathine penicillin. It is suggested that the sustained therapeutic levels of penicillin were effective either by the inhibition of germ replication or by lysis of the spirochaetes when they were leaving their sanctuaries.

    Clements, J; Dinneen, A; Heilpern, G

    2013-03-01

    Septic arthritis is an uncommon condition with an incidence of 2-3/100,000. It is clinically notable, however, as it is a rapidly destructive joint disease with significant associated morbidity and mortality. Polyarticular septic arthritis has an estimated incidence of 15% of all cases of infectious arthritis. We report a case of polyarticular septic arthritis with involvement of bilateral shoulders and wrist to highlight the importance of early diagnosis and treatment as well as the high mortality rates associated with this condition. Bilateral septic shoulder arthritis poses a challenge to treat, and its significance should not be underestimated as even with early surgical intervention and aggressive antibiotic and fluid resuscitation death is a sad but perhaps not uncommon outcome. It is therefore imperative that the diagnosis of polyarticular septic arthritis is kept prominent in the physician's mind when confronted with a patient with symptomatic polyarthralgia.

    Since the introduction of type b Haemophilus influenzae vaccination, noncapsulated H. influenzae has become responsible for most cases of invasive H. influenzae diseases. In our two cases of septic arthritis, we isolated strains with β-lactamase-positive amoxicillin-clavulanate resistance (BLPACR). Thus, the increasing prevalence of BLPACR should be taken into account when empirical therapy is chosen for septic arthritis. PMID:23515545

    A 6 yr old female spayed Labrador retriever was examined for severe pain and a nonweight-bearing right forelimb lameness due to swelling and wounds with direct communication into the elbow joint. The medical management of β hemolytic Streptococcus septic arthritis with needle lavage of the joint, systemic and local antibiotic therapy, and analgesic therapy is described. This case provides information on the need to address septic arthritis in the dog as an emergency situation and the treatment with intra-articular medication. Earlier medical management for septic joints could be considered in dogs to help decrease the long-term complications that can result from septic arthritis.

    Lameness related to synovial infection needs to be addressed promptly because rapid degradation of the synovial homeostasis results in permanent cartilage alterations detrimental to complete recovery. Diagnosis is based on clinical signs, synovial fluid analysis, and imaging. Commonly affected joints are the fetlock, carpus, tarsus, and stifle; shoulder, elbow, and hip may also be infected. Knowing the source of infection is essential in cases of remote septic arthritis. Antimicrobials should be administered; local delivery systems may be used. Therapy relies on the removal of inflammatory mediators. Pain management is critical throughout the surgical procedures and the recovery period.

    Objective: To evaluate whether a three month course of lymecycline has an effect on the long term prognosis of reactive arthritis (ReA). Methods: In 1987–88 a double-blind controlled study with three month course of lymecycline/placebo was conducted. 17 of 23 patients treated at the outpatient department of Helsinki University Central Hospital volunteered to take part in a follow up study, where a physical examination were performed, and erythrocyte sedimentation rate, C reactive protein, rheumatoid factor, and radiographs of the lumbosacral spine and sacroiliac joints and of symptomatic peripheral joints were examined. Results: 16/17 (94%) patients reported some kind of back pain and 10/17 (59%) peripheral joint symptoms during the follow up. Two patients had unilateral grade 1 sacroiliitis, one patient grade 4 sacroiliitis, and one patient bilateral grade 2 sacroiliitis. In one patient the disease had progressed to ankylosing spondylitis (AS), and in another to chronic spondyloarthropathy. In addition, two patients had small erosions in radiocarpal joints. No statistically significant differences were found between placebo and lymecycline groups in the development of chronic arthritis, sacroiliitis, or AS. Conclusion: The results of the initial study showed that long term treatment with lymecycline in patients with acute ReA decreased the duration of arthritis in those with Chlamydia trachomatis triggered ReA, but not in other patients with ReA. Ten years after the acute arthritis one patient had developed AS, and three had radiological sacroiliitis, three patients had radiological changes at peripheral joints. Long term lymecycline treatment did not change the natural history of the disease. PMID:12810429

  3. Treatment of acute septic arthritis.

    Pääkkönen, Markus; Peltola, Heikki

    2013-06-01

    Acute septic arthritis is a rare, but potentially devastating disease. The treatment is initiated intravenously, but can be safely switched to oral after 2-4 days providing large doses of a well-absorbing antibiotic and, for time-dependent antibiotics, 4 times-a-day administration are used. Empiric treatment should always cover Staphylococcus aureus and common respiratory pathogens, whereas Kingella kingae and Salmonella are important only regionally. Studies conducted by our group have shown that a total course of 10 days may suffice for previously healthy children in a Western setting. Treatment of neonates, patients with immunodeficiency or cases caused by methicillin-resistant S. aureus, may deserve a different approach.

    Little information is available about several important aspects of the treatment of melioidosis osteomyelitis and septic arthritis. We undertook a retrospective review of 50 patients with these conditions in an attempt to determine the effect of location of the disease, type of surgical intervention and duration of antibiotic treatment on outcome, particularly complications and relapse. We found that there was a 27.5% risk of osteomyelitis of the adjacent bone in patients with septic arthritis in the lower limb. Patients with septic arthritis and osteomyelitis of an adjacent bone were in hospital significantly longer (p = 0.001), needed more operations (p = 0.031) and had a significantly higher rate of complications and re-presentation (p = 0.048). More than half the patients (61%), most particularly those with multifocal bone and joint involvement, and those with septic arthritis and osteomyelitis of an adjacent bone who were treated operatively, needed more visits to theatre.

    Septic arthritis is a debilitating acute orthopedic emergency. Unfortunately, the diagnosis can be delayed or missed in immunocompromised patients with diabetes mellitus, and the result can be catastrophic. These patients are also at risk for atypical infections, including mycotic subtypes, which are more insidious than their more aggressive, more common Staphylococcus counterparts. The result is increased morbidity. In this article, we report a case of Candida albicans septic arthritis in a patient with diabetes mellitus and rheumatoid arthritis. Her case highlights the complexities of this specific disease entity. With early diagnosis, treatment is multimodal, involving surgical débridement and prolonged antifungal therapy.

    2014-01-01

    Osteoarthritis of knee is one of the common problems in elderly population. Intraarticular corticosteroid injection is a conservative management modality in osteoarthritis of knee. Septic arthritis is an infective complication of intraarticular corticosteroid injection. Septic arthritis in rheumatoid arthritis patients have worse prognosis because of delay in diagnosis. A higher rate of infectious complications following intraarticular injection is expected in immunocompromised and rheumatoid patients. We would like to report an extremely rare case of simultaneous bilateral knee septic arthritis after bilateral knee intraarticular steroid injection in a rheumatoid arthritis patient. Patient was treated successfully with multiple bilateral knee arthroscopic washouts and long-term intravenous antibiotics. This case report emphasizes the increased risk of infection in rheumatoid arthritis patients and a risk benefit assessment on individual basis before carrying out intraarticular steroid injection. Patient should be aware of this increased risk of infection. PMID:25097444

    Septic arthritis of the hand and wrist is relatively uncommon. The most common cause is penetrating trauma such as a human or animal bite. The most common causative organism is Staphylococcus aureus. Septic arthritis caused by Streptococcal species. Haemophilus influenzae, Pseudomonas aeruginosa, Serratia species, Neisseria gonorrhoeae, Pasteurella multocida, Eikenella corrodens, and Mycobacterium marinum also may occur in specific clinical settings. The best clinical results occur following an accurate diagnosis, prompt surgical drainage, and debridement in concert with appropriate antibiotics and early postoperative range of motion. A delay in diagnosis or treatment is associated with an unsatisfactory outcome.

    2009-01-01

    Septic arthritis of the hip is the commonest septic condition during growth, reaching a distinct peak in frequency during infancy. The aetiology is a haematogenous joint infection. Indicative signs are severe pain when moving the joint, septic appearance and a poor general condition of these small and young patients. The diagnosis often can be difficult in infants since septic temperatures are not always present. An ultrasound scan shows the hip joint effusion and the capsular distension. X-ray investigation helps to exclude defective situations. Therapeutic options are: in patients with short history without radiologically visible complications we recommend repeated arthroscopic irrigation and in patients with long history and a radiologically visible defect of the femoral head or dislocation we recommend arthrotomy and open revision or reduction of the hip joint.

    Clostridium species are anaerobic bacilli that are rarely reported as etiologic agents of infectious arthritis. Previous cases of arthritis caused by Clostridium ramosum have not been reported. We describe the first 2 cases of C. ramosum arthritis. We reviewed the etiology of arthritis in our hospital during the previous 15 years. Both patients had underlying immunocompromising conditions and their infections involved a joint with preexisting disease: patient 1 had rheumatic arthritis and a prosthetic joint; patient 2, chronic renal failure on dialysis and hip osteoarthritis. The infection was hematogenously acquired and the course was indolent but destructive in both the cases. Management included open arthrotomy and resection arthroplasty. The infection had a persisting and relapsing course, and prolonged antibiotic treatment was required. In the literature review, we found 55 previous cases of arthritis caused by Clostridium species between 1966 and 2014; Clostridium perfringens was the most common infecting species; the infection was traumatically acquired in most of the cases. A total of 15 patients have been described with infections caused by C. ramosum; none had septic arthritis. The majority were elderly or immunocompromised adults. Proper collection, transportation and processing of clinical specimens is essential for diagnosing clostridial infections. More information about the best management of clostridial arthritis are needed. We describe the first 2 cases of septic arthritis caused by C. ramosum. They shared several pathogenic and clinical features. The possibility of anaerobic arthritis should always be considered when collecting diagnostic specimens. An increasing number of clostridial arthritis cases are likely to be diagnosed in future years. Copyright © 2016 Elsevier Inc. All rights reserved.

    Septic polyarthritis is rarer than septic monoarthritis, but associated with higher mortality. Septic polyarthritis may be difficult to distinguish clinically from noninfectious inflammatory arthritis. We describe one of the largest samples of septic polyarthritis with the aim of distinguishing septic monoarthritis from polyarthritis. We conducted a retrospective study of adults admitted to tertiary care with septic monoarthritis and polyarthritis. Baseline characteristics, microbial profiles, joint involvement, length of stay, and 60-day readmission rates were determined. We identified 464 and 42 cases of septic monoarthritis and polyarthritis, respectively, including 7 cases of septic polyarthritis with comorbid rheumatoid arthritis. Compared to those with septic monoarthritis, patients with septic polyarthritis were more likely to have rheumatoid arthritis (p < 0.01), sepsis (p < 0.01), and higher peripheral (p < 0.001) and synovial (p < 0.001) white blood cell counts. Operative intervention rates were similar, but mean length of stay was longer in polyarticular septic arthritis (p < 0.001). Patients with septic polyarthritis with/without underlying rheumatoid arthritis were similar in terms of presenting features and outcomes, except for more frequent immunosuppressive therapy in rheumatoid arthritis (p < 0.01). In this sample of patients with septic arthritis, patients with septic polyarthritis were more likely to have systemic infection at presentation than those with septic monoarthritis. Despite this difference, patients with septic monoarthritis and polyarthritis tended to have similar outcomes. While rheumatoid arthritis was observed more frequently among patients with septic polyarthritis, those with/without underlying rheumatoid arthritis had similar presenting features and outcomes.Bottom of Form.

    Septic arthritis of the temporomandibular joint (TMJ) is a rare event that has only been reported a few dozen times worldwide. This case is remarkable for septic arthritis of the TMJ joint in an otherwise healthy male. Case Report: A 24-year-old male presented to the emergency department with periauricular swelling, erythema, fever, myalgia's and generalized joint pain. He had previously sought medical attention and was placed on ciprofloxacin. However, he developed facial swelling and a rash and had to discontinue the antibiotic. On physical exam the patient had a large swelling and tenderness in his left periauricular area, with erythema and deviation of the right mandible which limited his ability to open the mouth. A computed tomography showed mild asymmetric soft tissue swelling in the left pharyngeal region but did not show joint effusion. Subsequent magnetic resonance imaging did show effusion of the joint space. The effusion was drained, and the synovial fluid was submitted for gram stain, culture, and sensitivity. The cultures grew menthicillin sensitive Staphyloccocus Aureus. The patient was discharged to complete a two week course of intravenous (IV) Ceftriaxone and IV Vancomycin via home infusion. Conclusion: Septic Arthritis of the TMJ is a rare event with very specific clinical symptoms. Due to the low sensitivity of the computed tomography scan, magnetic resonance imaging should be considered when computed tomography scan is negative for TMJ effusion. PMID:26713295

    Background Acutely swollen or painful joints are common complaints in the emergency department (ED). Septic arthritis in adults is a challenging diagnosis, but prompt differentiation of a bacterial etiology is crucial to minimize morbidity and mortality. Objectives The objective was to perform a systematic review describing the diagnostic characteristics of history, physical examination, and bedside laboratory tests for nongonococcal septic arthritis. A secondary objective was to quantify test and treatment thresholds using derived estimates of sensitivity and specificity, as well as best-evidence diagnostic and treatment risks and anticipated benefits from appropriate therapy. Methods Two electronic search engines (PUBMED and EMBASE) were used in conjunction with a selected bibliography and scientific abstract hand search. Inclusion criteria included adult trials of patients presenting with monoarticular complaints if they reported sufficient detail to reconstruct partial or complete 2 × 2 contingency tables for experimental diagnostic test characteristics using an acceptable criterion standard. Evidence was rated by two investigators using the Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS). When more than one similarly designed trial existed for a diagnostic test, meta-analysis was conducted using a random effects model. Interval likelihood ratios (LRs) were computed when possible. To illustrate one method to quantify theoretical points in the probability of disease whereby clinicians might cease testing altogether and either withhold treatment (test threshold) or initiate definitive therapy in lieu of further diagnostics (treatment threshold), an interactive spreadsheet was designed and sample calculations were provided based on research estimates of diagnostic accuracy, diagnostic risk, and therapeutic risk/benefits. Results The prevalence of nongonococcal septic arthritis in ED patients with a single acutely painful joint is approximately 27

    Current diagnostic methods in differentiating septic from non-septic arthritis are time-consuming (culture) or have limited sensitivity (Gram stain). Microcalorimetry is a novel method that can rapidly detect microorganisms by their heat production. We investigated the accuracy and time to detection of septic arthritis by using microcalorimetry. Patients older than 18 years of age with acute arthritis of native joints were prospectively included. Synovial fluid was aspirated and investigated by Gram stain, culture and microcalorimetry. The diagnosis of septic arthritis and non-septic arthritis were made by experienced rheumatologists or orthopaedic surgeons. Septic arthritis was diagnosed by considering the finding of acute arthritis together with findings such as positive Gram stain or positive culture of synovial fluid or positive blood culture. The sensitivity and specificity for diagnosing septic arthritis and the time to positivity of microcalorimetry were determined. Of 90 patients (mean age 64 years), nine had septic arthritis, of whom four (44 %) had positive Gram stain, six (67 %) positive synovial fluid culture and four (44 %) had positive blood culture. The sensitivity of microcalorimetry was 89 %, the specificity was 99 % and the mean detection time was 5.0 h (range, 2.2-8.0 h). Microcalorimetry is an accurate and rapid method for the diagnosis of septic arthritis. It has potential to be used in clinical practice in diagnosing septic arthritis.

    The incidence of infection by Mycobacterium marinum is rising, mainly due to the increasing popularity of home aquariums. The infection typically manifests as skin lesions, with septic arthritis being a rare presentation form. The disease is difficult to diagnose even when there is a high clinical suspicion, as culture in specific media may not yield positive findings. Thus, establishment of appropriate treatment is often delayed. Synovectomy, capsular thinning, and joint drainage together with prolonged, combined antibiotic therapy may be needed to cure the infection.

    Cellulosimicrobium cellulans has been reported as a rare cause of human pathogenesis. Infections mainly occur in immunocompromised patients and very often are associated with a foreign body. We report the first case of septic arthritis caused by C. cellulans in an immunocompetent patient. Our patient suffered a penetrating palm tree thorn injury to his left knee 8 weeks before admission. Although no foreign objects were found, they were suspected because previous reports suggest a frequent association with this microorganism, and open debridament was performed. Removal of foreign bodies related to this organism must be considered a high-priority treatment in these patients to achieve a complete recovery. PMID:21998421

  2. Bone and Joint Infections in Children: Septic Arthritis.

    PubMed

    2016-08-01

    The pathological invasion of a joint and subsequent inflammation is known as septic arthritis. The knee and hip are the most frequently involved joints. Staphylococcus aureus is the most common cause of septic arthritis in children. An acute onset of illness with an inflamed painful joint and restricted movements and inability to use joint (pseudoparalysis) clinically indicates septic arthritis. The diagnosis is difficult in a neonate or young child where refusal to feed, crying, discomfort during change of diaper (if hip is involved) or attempted joint movement may be the only findings. Fever and other systemic signs may also be absent in neonates. Septic arthritis is diagnosed clinically, supported by appropriate radiological and laboratory investigations. The peripheral blood white cell count is frequently raised with a predominance of polymorphonuclear cells. The acute phase reactants such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are often markedly raised. Ultrasonography and MRI are preferred investigations in pediatric septic arthritis. Determination of infecting organism in septic arthritis is the key to the correct antibiotic choice, treatment duration and overall management. Joint aspirate and/or blood culture should be obtained before starting antibiotic treatment. Several effective antibiotic regimes are available for managing septic arthritis in children. Presence of large collections, thick pus, joint loculations and pus evacuating into surrounding soft tissues are main indications for surgical drainage. Joint aspiration can be a practical alternative in case the lesion is diagnosed early, with uncomplicated presentations and superficial joints.

    Septic pyogenic arthritis of the acromioclavicular joint is a rare entity that occurs in immunosuppressed patients or those with discontinuity of defense barriers. There are only 15 cases described in the literature. The diagnosis is based on clinical features and the isolation of a microorganism in synovial fluid or blood cultures. The evidence of arthritis by imaging (MRI, ultrasound or scintigraphy) may be useful. Antibiotic treatment is the same as in septic arthritis in other locations. Staphylococcus aureus is the microorganism most frequently isolated. Our objective was to describe the clinical features, treatment and outcome of patients diagnosed with septic arthritis of the acromioclavicular joint at a Rheumatology Department. We developed a study with a retrospective design (1989-2012). The medical records of patients with septic arthritis were reviewed (101 patients). Those involving the acromioclavicular joint were selected (6 patients; 6%).

    Soil absorption systems (SAS) are used commonly to treat and disperse septic tank effluent (STE). SAS can hydraulically fail as a result of the low permeable biomat zone that develops on the infiltrative surface. The objectives of this experiment were to compare the hydraulic properties of biomats grown in soils of different textures, to investigate the long-term acceptance rates (LTAR) from prolonged application of STE, and to assess if soils were of major importance in determining LTAR. The STE was applied to repacked sand, Oxisol and Vertisol soil columns over a period of 16 months, at equivalent hydraulic loading rates of 50, 35 and 8L/m(2)/d, respectively. Infiltration rates, soil matric potentials, and biomat hydraulic properties were measured either directly from the soil columns or calculated using established soil physics theory. Biomats 1 to 2 cm thick developed in all soils columns with hydraulic resistances of 27 to 39 d. These biomats reduced a 4 order of magnitude variation in saturated hydraulic conductivity (K(s)) between the soils to a one order of magnitude variation in LTAR. A relationship between biomat resistance and organic loading rate was observed in all soils. Saturated hydraulic conductivity influenced the rate and extent of biomat development. However, once the biomat was established, the LTAR was governed by the resistance of the biomat and the sub-biomat soil unsaturated flow regime induced by the biomat. Results show that whilst initial soil K(s) is likely to be important in the establishment of the biomat zone in a trench, LTAR is determined by the biomat resistance and the unsaturated soil hydraulic conductivity, not the K(s) of a soil. The results call into question the commonly used approach of basing the LTAR, and ultimately trench length in SAS, on the initial K(s) of soils.

    Septic arthritis is a rapidly destructive form of joint disease. The most common causative agents in children are Staphylococcus aureus and Kingella kingae, followed by group A Streptococcus and Streptococcus pneumoniae, and in neonates, enterobacteracea and group B Streptococcus. In this paper, we describe a previously healthy toddler with septic arthritis of the shoulder joint caused by Brevundimonas vesicularis. Prompt treatment with cefuroxime resulted in a full recovery. This is the first report of septic arthritis in humans caused by this microorganism, and the first description of B. vesicularis infection in an immunocompetent child.

    Kingella kingae is a slow-growing, fastidious gram-negative coccobacillus that is a normal inhabitant of the oropharynx of man, but it has rarely been implicated as a human pathogen. Two cases of septic arthritis caused by this organism are reported along with a review of seven previously reported cases of infections caused by this organism. Bone and joint infections predominate. Gram's-stained smears of pus from bone or joint fluid aspirate have been negative for organisms, and a delay of growth in cultures with initial difficulty in classification of the isolate is characteristic. Kingella kingae organisms have been uniformly sensitive to the penicillins and all other commonly used antibiotics that were tested. Response to treatment was good in all nine patients found to have infections caused by this organism.

    Non-typhoidal Salmonella, particularly Salmonella enterica serovar typhimurium is food borne pathogen causing mild self-limiting diarrhoea in healthy adults. It can occasionally cause extraintestinal focal infection in susceptible patients. Salmonella, as the aetiological agent of osteomyelitis and septic arthritis is rare and has been mostly reported in patients with sickle cell disease or thalassaemia. We report a case of septic arthritis by Salmonellatyphimurium in an immunocompromised patient who was successfully treated following timely isolation and identification of the aetiological agent.

    The technetium phosphate bone scans of 106 children with suspected septic arthritis were reviewed to determine whether the bone scan can accurately differentiate septic from nonseptic arthropathy. Only 13% of children with proved septic arthritis had correct blind scan interpretation. The clinically adjusted interpretation did not identify septic arthritis in 30%. Septic arthritis was incorrectly identified in 32% of children with no evidence of septic arthritis. No statistically significant differences were noted between the scan findings in the septic and nonseptic groups and no scan findings correlated specifically with the presence or absence of joint sepsis.

    1981-01-01

    Synovial fluid lactic acid estimations were carried out on 50 samples by gas liquid chromatography. Specimens from 4 patients with bacteria arthritis, other than gonococcal, had a mean lactic acid concentration of 215 mg/dl. One patient with gonococcal arthritis had a synovial fluid lactic acid of 30 mg/dl. Forty-one patients with inflammatory arthritis and 4 patients with degenerative arthritis had mean synovial fluid lactic acid levels of 27 and 23 mg/dl respectively. The estimation of synovial fluid lactic acid is reliable in differentiating septic arthritis from inflammatory and degenerative arthritis except when the infecting organism is NEisseria gonorrhoeae.

    Septic arthritis is a devastating condition; well-established criteria for diagnosis exist in the pediatric population, but not for adults. This study evaluated patient factors and laboratory parameters that may be associated with the diagnosis of septic arthritis in adults. A total of 458 knee aspirates for suspected septic arthritis were evaluated with serum and synovial leukocyte counts and differentials as well as Kocher criteria for pediatric septic arthritis. Twenty-two patients (4.8%) had septic arthritis confirmed by a positive synovial fluid culture. Erythrocyte sedimentation rate (ESR) and serum white blood cell (WBC) counts were not statistically different between the 2 groups, with 64% of septic arthritis patients having a normal serum WBC count and 77% being afebrile. Mean synovial fluid WBC count was 26,758 cells/µL and 70,581 cells/µL in the nonseptic and septic groups, respectively. The likelihood ratio for a synovial fluid WBC count greater than 65,000 cells/µL was 2.8 (95% confidence interval, 1.2-6.7). Evaluation receiver operating characteristic curves using synovial WBC counts resulted in a significant area under the curve of 0.66 (P=.02). To achieve 90% specificity, a WBC cutoff of 64,000 cells/µL was required with a corresponding sensitivity of 40%. There was no significant difference in the synovial cell differential of 80% vs 90% in diagnosing infection. Synovial fluid WBC count greater than 64,000 cells/µL yielded the optimal combination of sensitivity and specificity. Polymorphonuclear leukocytes, ESR, serum WBC count, fever, and weight-bearing status were not significant predictors of septic arthritis. This study demonstrates the limited utility of Kocher criteria in the adult population and the importance of synovial leukocyte counts. [Orthopedics. 2016; 39(4):e657-e663.].

    In the randomized autopsy material of 161 patients with rheumatoid arthritis (RA), a letal, generalized septic infection (GSI) was observed in 22 cases (13.66%). The GSI was accompanied by a pyarthros in 12 (7.45%) and no pyarthros in 10 (6.21%) cases. The clinical parameters of 22 septic RA patients were compared with 139 age and sex matched RA patients without GSI. The average age of septic patients decreased (p < 0.02), with low serum electrophoretic b-globulin level (p < 0.04), and high Waaler-Rose (p < 0.02) and Latex level (p < 0.004). The clinical parameters of 22 septic patients were compared with 76 age and sex matched RA patients without sepsis, vasculitis, or generalized secondary amyloidosis (GSA), and/or miliary epitheloid granulomas of tuberculous type (mT). The differences between the two groups of patients were the same, with a statistically more pronounced age difference (p < 0.005). 29 out of 161 patients (18.01 %) suffered from a clinically manifest diabetes mellitus (in 6 patients accompanied by sepsis), and 11 (6.83 %) from a clinically latent diabetes mellitus (in 2 patients accompanied by sepsis). There was no significant relationship between sepsis and manifest diabetes mellitus. The controlled and treated diabetes mellitus does not influence the frequency of lethal sepsis. Significant correlations were found between sepsis and latent diabetes mellitus (based on the histological detection of amyloid deposition localized to the islets of Langerhans (p < 0.02). 34 out of 161 patients (21.12%) suffered from a generalized secondary amyloidosis (in 3 patients accompanied by sepsis). There was no significant relationship between sepsis and generalized secondary amyloidosis. The thickness of adrenal cortex represents the effect of steroid therapy. Critical random check, using the Mann-Whitney tests, supports significance relationship between the adrenal cortex atrophy and fatal sepsis (p < 0.010).

    To analyse the association between alcohol intake and incidence of rheumatoid arthritis in women. Prospective cohort study with repeated measurements. The Swedish Mammography Cohort, a population based cohort from central Sweden. 34,141 women born between 1914 and 1948, followed up from 1 January 2003 to 31 December 2009. Newly diagnosed cases of rheumatoid arthritis identified by linkage with two Swedish national registers. Data on alcohol consumption were collected in 1987 and 1997. During the follow-up period (226,032 person years), 197 incident cases of rheumatoid arthritis were identified. There was a statistically significant 37% decrease in risk of rheumatoid arthritis among women who drank >4 glasses of alcohol (1 glass = 15 g of ethanol) per week compared with women who drank <1 glass per week or who never drank alcohol (relative risk 0.63 (95% confidence interval 0.42 to 0.96), P = 0.04). Drinking of all types of alcohol (beer, wine, and liquor) was non-significantly inversely associated with the risk of rheumatoid arthritis. Analysis of long term alcohol consumption showed that women who reported drinking >3 glasses of alcohol per week in both 1987 and 1997 had a 52% decreased risk of rheumatoid arthritis compared with those who never drank (relative risk 0.48 (0.24 to 0.98)). Moderate consumption of alcohol is associated with reduced risk of rheumatoid arthritis.

    This study aimed at determining the sensitivity and specificity of Gram staining of synovial fluid as a diagnostic tool in acute septic arthritis. A retrospective study was made of 22 patients who had arthroscopic lavage following a provisional diagnosis of acute septic arthritis of the knee joint. Gram stains and cultures of the knee aspirates were compared with the clinical and laboratory parameters, to evaluate their usefulness in diagnosing acute arthritis. All patients who had septic arthritis had pain, swelling and limitation of movement. CRP was elevated in 90% of patients. The incidence of elevated white blood cell count was higher in the group of patients with a positive Gram stain study (60%) as compared to patients with a negative Gram stain study (33%). Gram staining sensitivity was 45%. Its specificity was however 100%. Gram staining is an unreliable tool in early decision making in patients requiring urgent surgical drainage and washout.

    A 23-year-old collegiate football player reported to the training room the day after a game, complaining of severe pain in his right shoulder. He recalled no significant injury during the game. Physical examination revealed pain, tenderness, and apprehension with all attempts to palpate or move the joint. There was no obvious effusion, redness, or warmth about the shoulder joint. The neurovascular examination was negative, and x-rays revealed no fracture. The patient's temperature was 102 degrees F. The team orthopedist aspirated 10cc of purulent fluid from the joint. Subsequent analysis revealed a white cell count greater than 50,000 mm(3), but no organisms were seen. The diagnosis of septic arthritis was made on the basis of the elevated cell count of the joint aspirate, in conjunction with fever (102 degrees F) and the clinical findings of an excessively painful joint. The patient was admitted for arthroscopic irrigation and debridement of the joint. Cultures subsequently showed a light growth of a Gram-negative organism. The patient was treated initially with intravenous broad-spectrum antibiotics and was ultimately discharged and put on oral antibiotics at the time of discharge. Rehabilitation followed the usual protocol for diagnostic arthroscopy, and the patient made an excellent recovery. He has had no residual sequelae or recurrence of infection.

    Objective To test whether elevated concentration of rheumatoid factor is associated with long term development of rheumatoid arthritis. Design A prospective cohort study, the Copenhagen City Heart Study. Blood was drawn in 1981-83, and participants were followed until 10 August 2010. Setting Copenhagen general population. Participants 9712 white Danish individuals from the general population aged 20-100 years without rheumatoid arthritis at study entry. Main outcome measures Rheumatoid arthritis according to baseline plasma IgM rheumatoid factor level categories of 25-50, 50.1-100, and >100, versus <25 IU/mL. Results Rheumatoid factor levels were similar from age 20 to 100 years. During 187 659 person years, 183 individuals developed rheumatoid arthritis. In healthy individuals, a doubling in levels of rheumatoid factor was associated with a 3.3-fold (95% confidence interval 2.7 to 4.0) increased risk of developing rheumatoid arthritis, with a similar trend for most other autoimmune rheumatic diseases. The cumulative incidence of rheumatoid arthritis increased with increasing rheumatoid factor category (Ptrend<0.0001). Multivariable adjusted hazard ratios for rheumatoid arthritis were 3.6 (95% confidence interval 1.7 to 7.3) for rheumatoid factor levels of 25-50 IU/mL, 6.0 (3.4 to 10) for 50.1-100 IU/mL, and 26 (15 to 46) for >100 IU/mL, compared with <25 IU/mL (Ptrend<0.0001). The highest absolute 10 year risk of rheumatoid arthritis of 32% was observed in 50-69 years old women who smoked with rheumatoid factor levels >100 IU/mL. Conclusion Individuals in the general population with elevated rheumatoid factor have up to 26-fold greater long term risk of rheumatoid arthritis, and up to 32% 10 year absolute risk of rheumatoid arthritis. These novel findings may lead to revision of guidelines for early referral to a rheumatologist and early arthritis clinics based on rheumatoid factor testing. PMID:22956589

    Septic arthritis are serious infections rarely observed for the temporomandibular joint. They are mainly hematogenous or transmitted by contiguity. Our patient presents the case of an infection of the temporomandibular joint by maxillary sinusitis of dental origin further complicated by cerebral abscess and empyema. Initial treatment consisted of an endonasal and intraoral drainage, intravenous empirical antibiotic therapy, a close clinicoradiological monitoring, and rehabilitation following a long-term active physiotherapy. Furthermore, the patient reported the onset of a dental articulation disorder with a left side premature contact and right lateral open bite, corresponding to a significant left condylar resorption. This infectious disease is very rare for temporomandibular location; however, its general and functional outcome is determined by the precocity of the treatment. It is important to know the diagnosis and the associated symptoms even if they are not very specifically described. It is essential to consider the diagnosis when facing atypical pain of the temporomandibular joint associated with trismus. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    The clinical presentation of a monoarticular, red, hot, and swollen joint has many possible diagnoses, including septic arthritis, which is 1 of the most devastating. The morbidity associated with this pathologic process involves permanent joint damage and the potential for progression to systemic illness and, even, mortality. The common risk factors for joint sepsis include a history of rheumatoid arthritis, previous joint surgery, joint prosthesis, intravenous drug abuse, alcoholism, diabetes, previous intra-articular steroid use, and cutaneous ulceration. The diagnosis is primarily determined from the culture results after arthrocentesis and correlation with direct visualization, imaging, and various serologies, including synovial analysis. In the present report, a case of an insidious presentation of subtalar joint septic arthritis and its association with a unique patient presentation concomitant with primary immunodeficiency and culture-proven Myocplasma hominis infection is discussed. Septic arthritis has a predilection for the lower extremities and typically is isolated to the hip or knee, with less common involvement of the ankle or metatarsophalangeal joints. Owing to the uncommon nature of primary immunodeficiency disorders and the paucity of studies discussing their association with septic arthridites, we aimed to raise awareness of subtalar joint septic arthritis and to provide a brief overview of the pathogenesis as it presented in a 33-year-old male with X-linked hypogammaglobulinemia/agammaglobulinema.

    Septic arthritis of the knee is encountered on a regular basis by orthopedists and nonorthopedists. No established therapeutic algorithm exists for septic arthritis of the knee, and there is much variability in management. This study assessed the number of surgical procedures, arthroscopic or open, required to eradicate infection. The study was a retrospective analysis of 79 patients who were treated for septic knee arthritis from 1995 to 2011. Patients who were included in the study had native septic knee arthritis that had resolved with treatment consisting of irrigation and debridement, either open or arthroscopic. Logistic regression analysis was used to explore the relation between the interval between onset of symptoms and index surgery and the use of arthroscopy and the need for multiple procedures. Fifty-two patients met the inclusion criteria, and 53% were male, with average follow-up of 7.2 years (range, 1-16.2 years). Arthroscopic irrigation and debridement was performed in 70% of cases. On average, successful treatment required 1.3 procedures (SD, 0.6; range, 1-4 procedures). A significant relation (P=.012) was found between time from presentation to surgery and the need for multiple procedures. With arthroscopic irrigation and debridement, most patients with septic knee arthritis require only 1 surgical procedure to eradicate infection. The need for multiple procedures increases with time from onset of symptoms to surgery.

    We describe a case of septic arthritis in a native knee due to Corynebacterium striatum, gram-positive bacilli that are usually commensal organisms of skin and mucosal membranes, but are seldom implicated in native septic arthritis. An 84-year-old man with Corynebacterium striatum septic arthritis of his native left knee and no response to conventional antibiotic therapy. Thus, the patient was allowed to take dalbavancin for compassionate use, with an excellent clinical outcome. This case emphasizes de role of Corynebacterium striatum in native joint infections and highlights the importance of early detection and appropriate treatment in improving the clinical outcome.

    Objective Remission is rapidly becoming a key endpoint in rheumatoid arthritis clinical trials, but its definition is not satisfactory. Although it is generally believed that achieving a state of remission will lead to better structural outcome, this has not been studied systematically. As a part of an undertaking to redefine remission, the current review describes the relationship between remission and long term structural outcome. Methods A systematic literature search of PubMed, Embase.com, and the Cochrane Library intersected three groups of terms: rheumatoid arthritis, remission and long term outcome. The search identified 1138 records, of which 14 were relevant to the research question. Results All the studies included in this review showed a relationship between remission and long term structural damage or disability. Patients that achieved a state remission, defined in various ways, showed less deterioration of function and radiographic progression compared to patients who did not reach a state of remission. Conclusion Patients who achieve a state of remission are less likely to show deterioration of function and radiographic progression compared to patients that do not reach a state of remission.

    Non-typhoidal Salmonella, particularly Salmonella enterica serovar typhimurium is food borne pathogen causing mild self-limiting diarrhoea in healthy adults. It can occasionally cause extraintestinal focal infection in susceptible patients. Salmonella, as the aetiological agent of osteomyelitis and septic arthritis is rare and has been mostly reported in patients with sickle cell disease or thalassaemia. We report a case of septic arthritis by Salmonella typhimurium in an immunocompromised patient who was successfully treated following timely isolation and identification of the aetiological agent.

    Vibrio vulnificus is a rare but potential fatal bacterium that can cause severe infections. Wound infections, primary sepsis and gastroenteritis are the most common clinical features. Septic arthritis caused by V. vulnificus is an atypical presentation that has been reported in only two case reports; however, it has not been previously noted in Denmark. The authors report a case of septic arthritis caused by V. vulnificus in an immunocompromised patient. The disease progressed to severe sepsis and subsequent death within 10 h of admission.

    X-linked agammaglobulinemia (XLA) is a primary immunodeficiency disease caused by mutations in the Bruton's tyrosine kinase (BTK) gene. XLA can also present in combination with juvenile idiopathic arthritis (JIA), the major chronic rheumatologic disease in children. We report herein the first known case of a juvenile patient diagnosed with XLA combined with JIA that later developed into invasive Klebsiella pneumoniae polyarticular septic polyarthritis. An additional comprehensive review of XLA combined with JIA and invasive K. pneumoniae septic arthritis is also presented. XLA was identified by the detection of BTK mutations while the diagnosis of JIA was established by clinical and laboratory assessments. Septic arthritis caused by invasive K. pneumoniae was confirmed by culturing of the synovia and gene detection of the isolates. Invasive K. pneumoniae infections can not only result in liver abscesses but also septic arthritis, although this is rare. XLA combined with JIA may contribute to invasive K. pneumoniae infection.

    We sought to determine the antiinflammatory properties of lymecycline in the long-term treatment of reactive arthritis (ReA). Quantitative assay of collagenase activity by densitometry after sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Therapeutic levels of lymecycline do not directly inhibit the activity of human neutrophil interstitial collagenase, but can prevent the oxidative activation of latent human neutrophil collagenase. This non-antimicrobial, anticollagenolytic property of lymecycline may contribute to its therapeutic efficacy in the treatment of patients with ReA.

    Brucellosis is one of the commonest zoonotic infections worldwide. The disease is endemic in Saudi Arabia, the Middle East, and the Mediterranean area. Osteoarticular involvement is a frequent manifestation of brucellosis. It tends to involve the sacroiliac joints more commonly; however, spondylitis and peripheral arthritis are increasingly reported. Brucellosis can be overlooked especially in the presence of companion bacteria. Hence, it should be suspected in all patients with septic arthritis in endemic areas or in patients visiting such areas. PMID:27200196

    We report a case of septic arthritis caused by a Bacillus species, B. pumilus, occurring in a healthy child. This organism rarely causes serious infections and has only been described in newborns and immunocompromised individuals or as a skin infection. This child developed an indolent joint swelling after a minor skin injury, and symptoms were initially thought most consistent with chronic arthritis. The case demonstrates that clinicians should consider joint infection in children presenting with acute monoarticular swelling, even without prominent systemic features.

  10. Septic Arthritis of the Pediatric Shoulder: From Infancy to Adolescence

    PubMed Central

    2016-01-01

    Background. Septic arthritis of the glenohumeral joint in the pediatric population (<18 yo) is not commonly described in the literature. There is a corresponding paucity of information regarding its presentation and treatment. Methods. An IRB approved review of patients treated with irrigation and debridement by the Orthopaedic Department was completed. This retrospective study includes four patients, presenting from 2005 to 2015, with septic arthritis of the shoulder. Results. The mean age (Mage) at presentation was 5 years, with a range of 1 month to 15 years. Patients presented on average after 7 days with pain and a mean temperature of 39°C, erythrocyte sedimentation rate of 66 mm/hr, a C-reactive protein level of 11.17 g/dL, and a white blood cell count of 20.2 × 103/mcL. Staphylococcus aureus, Candida albicans, and Pseudomonas aeruginosa were cultured from the wounds. All cases were treated operatively with irrigation and debridement and with antimicrobial therapy. Patients received antibiotics for an average of 6 weeks. Conclusion. Septic arthritis of the shoulder occurs in all pediatric ages. Successful treatment of septic arthritis of the shoulder was accomplished in four cases without division of the biceps sheath, with an average follow-up of 8 months. PMID:27635147

    Rheumatoid arthritis (RA) is associated with high morbidity and mortality predominately due to increased cardiovascular risk. Few reports are available regarding the management of coronary artery disease (CAD) in RA patients and the long-term clinical outcomes after coronary revascularization. All consecutive patients with RA were identified by retrospective review at a rheumatology tertiary center in Milan, Italy between 2001 and 2013. RA patients affected by significant CAD (RA-CAD+) were prospectively followed for major adverse cardiovascular and cerebrovascular events (MACCE) after percutaneous coronary revascularization (RA-PCI), coronary artery bypass grafting (RA-CABG) or medical therapy (RA-MT). Among 936 patients with RA, the presence of clinically significant CAD was found in 5.6% (53 patients, RA-CAD+). Of these, 32 patients (60%) underwent PCI (RA-PCI), 10 patients (19%) underwent CABG (RA-CABG) and 11 patients (21%) treated with MT (RA-MT). After a mean follow-up of 9±7 years, the rate of MACCE was 56% in RA-PCI patients, 50% in RA-CABG and 27% in RA-MT patients (P=0.184). The high MACCE rate was mainly driven by repeat coronary revascularization (47%) in the RA-PCI group and high rate of strokes (30%) in RA-CABG patients. In patients with rheumatoid arthritis and concomitant coronary artery disease (RA-CAD+), we observed at long-term follow-up a high MACCE rate, predominantly in those who underwent coronary revascularization.

    2015-10-01

    Septic arthritis of the sternoclavicular joint (SCJ) is a relatively rare disease. Due to serious complications including mediastinitis and generalised sepsis early diagnosis and rapid onset of treatment are mandatory. The disease often affects immunocompromised patients, diabetics, or patients with other infectious diseases. The therapeutic options range from administration of antibiotics to extended surgery including reconstructive procedures. Apart from rare situations where conservative treatment with antibiotics is sufficient, joint resection followed by plastic surgical procedures are required. We present a retrospective analysis with data from two hospitals. From January 2008 to December 2012 23 patients with radiographically confirmed septic arthritis of various aetiology were included. Fourteen (60.8 %) male, nine (39.2 %) female patients with an average age of 60.3 ± 14.2 years (range: 23-88 years) with septic arthritis of the SCJ were treated. Seven (30.4 %) patients suffered from Diabetes mellitus, nine (39.1 %) had underlying diseases with a compromised immune system. In 14 (60.8 %) out of 23 patients a bacterial focus was detected. Only six (26 %) patients suffered from confined septic arthritis of the SCG, in 17 (73,9 %) patients osteomyelitis of the adjacent sternum, and the clavicle was present. In addition, 15 (65.2 %) patients already suffered from mediastinitis at the time of diagnosis, eight (35 %) patients even from septicaemia. In conclusion, septic arthritis requires an active surgical treatment. Limited incision of the joint and debridement alone is only successful at early stages of the disease. The treatment concept has to include the local joint and bone resection as well as complications like mediastinitis. After successful treatment of the infection, the defect of the chest wall requires secondary reconstructive surgery using a pedicled pectoralis muscle flap.

    Septic arthritis/tenosynovitis in the horse can have life-threatening consequences. The purpose of this cross-sectional retrospective study was to describe ultrasound characteristics of septic arthritis/tenosynovitis in a group of horses. Diagnosis of septic arthritis/tenosynovitis was based on historical and clinical findings as well as the results of the synovial fluid analysis and/or positive synovial culture. Ultrasonographic findings recorded were degree of joint/sheath effusion, degree of synovial membrane thickening, echogenicity of the synovial fluid, and presence of hyperechogenic spots and fibrinous loculations. Ultrasonographic findings were tested for dependence on the cause of sepsis, time between admission and beginning of clinical signs, and the white blood cell counts in the synovial fluid. Thirty-eight horses with confirmed septic arthritis/tenosynovitis of 43 joints/sheaths were included. Degree of effusion was marked in 81.4% of cases, mild in 16.3%, and absent in 2.3%. Synovial thickening was mild in 30.9% of cases and moderate/severe in 69.1%. Synovial fluid was anechogenic in 45.2% of cases and echogenic in 54.8%. Hyperechogenic spots were identified in 32.5% of structures and fibrinous loculations in 64.3%. Relationships between the degree of synovial effusion, degree of the synovial thickening, presence of fibrinous loculations, and the time between admission and beginning of clinical signs were identified, as well as between the presence of fibrinous loculations and the cause of sepsis (P ≤ 0.05). Findings indicated that ultrasonographic findings of septic arthritis/tenosynovitis may vary in horses, and may be influenced by time between admission and beginning of clinical signs.

    2016-01-01

    Septic arthritis of the pubic symphysis is a potentially severe disease. Athletes are at risk of this form of spontaneous arthritis, as inflammation of the pubic bone due to muscular stress is relatively common. Oedema due to inflammation might predispose to infection through bacteraemia or local bacterial translocation. Suspicion should be raised when an athlete complains of groin pain and has signs of infection (i.e., fever, elevated white blood cell count, and elevated C-reactive protein). Diagnosis is made by imaging showing signs of inflammation combined with positive (blood) cultures. Broad spectrum antibiotics should be started upon suspicion and adjusted according to cultures. An abscess causing clinical deterioration under antibiotic treatment is an indication for invasive intervention (i.e., surgical or image-guided drainage). This is the first case of spontaneous septic arthritis of the pubic symphysis in an athlete requiring surgical and additional image-guided drainage. PMID:27703831

    The prodrug leflunomide is an immunomodulatory agent whose M1 metabolite inhibits the proliferation of T- and B-lymphocytes. The efficacy of leflunomide in rheumatoid arthritis suggests it may be useful psoriasis arthritis. Two patients with psoriasis arthritis in whom NSAIDs, glucocorticosteroids, sulfasalazine, cyclosporine and methotrexate were not as effective as expected were treated with leflunomide for 18 and 27 months. At regular visits examination of the joints (according to the ACR criteria) and the skin (PASI), the visual analogue scale for pain, and the quality of life (HAQ) were assessed. In both patients progression of the joint disease was arrested, pain reduced and quality of life improved. The cutaneous findings did not change, even though topical therapy was continued. Leflunomide is a long-term treatment option for patients with predominantly joint disease. In case of insufficient response, combination with other anti-inflammatory drugs, e.g. methotrexate, is possible. As leflunomide has little effect on psoriatic skin lesions, additional topical therapy is necessary.

    Sepsis-associated encephalopathy is a major complication during sepsis, and an effective treatment remains unknown. Although minocycline (MINO) has neuroprotective effects and is an attractive candidate for treating sepsis-associated encephalopathy, the effect of MINO on synaptic plasticity during sepsis is still unclear. In the present study, we investigated the effects of MINO on long-term potentiation (LTP) in the hippocampus in a cecal ligation and puncture (CLP) mouse model. We divided mice into 4 groups; (1) sham + vehicle, (2) sham + MINO (60 mg/kg, i.p. for 3 consecutive days before slice preparation), (3) CLP + vehicle, and (4) CLP + MINO. We tested LTP in the CA1 region of the hippocampus, using slices taken 24 h after surgery. Because MINO is also anti-inflammatory, LTP was analyzed following 30 min of IL-1 receptor antagonist (IL-1ra) perfusion. The endotoxin level in the blood was increased at 24 h after CLP operations regardless of MINO administrations, and LTP in the CLP + vehicle group mice was severely impaired (P < 0.05). High doses of MINO prevented the LTP impairment during sepsis in the CLP + MINO group. Interleukin (IL) -1ra administration ameliorated LTP impairment only in the CLP + vehicle group (P < 0.05); it had no additional effects on LTP in the CLP + MINO group. In conclusion, we have provided the first evidence that MINO prevents impaired LTP related to sepsis-induced encephalopathy in the mouse hippocampus, and that mechanisms associated with IL-1 receptor activity may be involved.

    Early diagnosis of septic arthritis is very important. Few studies showed diagnostic accuracy of serum inflammatory markers in septic arthritis. The aim of our study was to compare the serum and synovial fluid markers [procalcitonin, serum IL-6, TNF-α, C-reactive protein, erythrocyte sedimentation rate, synovial fluid white blood cell counts and PMN percentage] in septic and inflammatory arthritis. Seventy-five patients, including 25 and 50 septic and non-septic arthritis, were enrolled in the study. The serum and synovial fluid markers [procalcitonin, serum IL-6, TNF-α, C-reactive protein, erythrocyte sedimentation rate, synovial fluid white blood cell counts, and PMN percentage] were compared in septic and inflammatory arthritis. Patients with septic arthritis had significantly elevated levels of procalcitonin, serum TNF-α, C-reactive protein, erythrocyte sedimentation rate, synovial fluid white blood cell counts, and PMN percentage in comparison with the inflammatory arthritis group (P < 0.00). Serum IL-6 level does not differ among the two groups. In a receiver operating characteristic curve analysis, synovial fluid WBC counts, PMN percentage, TNF-α, ESR, and serum PCT preformed best in distinguishing between septic and non-septic arthritis. Our study suggests that PCT can be used to diagnose the septic arthritis, but more studies warranted in order to determine the specificity and sensitivity of the test.

    Clinical signs of acute arthritis are non-specific. An acute painfull joint with effusion of unknown origin needs to be evaluated by puncture. The analysis of the synovial fluid will enable to divide an arthritis into three categories: crystal induced, rheumatological or septic arthritis. A bacterial infection should always be suspected. Cultures from blood, synovia and Gram stain do not reliably exclude a bacterial infection. If gonococcal, mycobacterial, borrelial and non-gonococcal-infective arthritis under antibiotic therapy is suspected, direct DNA-amplification can be helpful. A disseminated gonococcal infection (DGI) must be suspected on appearance of tenosynovitis, polyarthralgia and skin lesions. The clinical picture, diagnosis and therapy of a case with DGI is discussed.

    We report three cases of septic arthritis in patients who presented with a painful, swollen and supurative knee joint following a recent arthroscopic procedure, 8–15 days prior to attendance. In all three cases, patients presented with pain and swelling of the affected knee joint with discharge from the port sites. All were sent for washout of the affected joint and received intravenous antibiotic cover. Any patient presenting within 1 month of a recent arthroscopic procedure with pain and swelling of that joint should be presumed to have septic arthritis until proven otherwise. They must have urgent treatment in the form of joint washout and intravenous antibiotics, and receive 6 weeks oral antibiotics on discharge. PMID:23345477

    2002-12-01

    Infection of the hip joint can cause severe articular damage. Standard treatment of septic arthritis includes surgical débridement and intravenous antibiotics. Options for definitive management in the presence of joint destruction include excision arthroplasty, arthrodesis, and total hip arthroplasty. Two cases of septic arthritis of the hip as a complication of femoral artery cannulation are presented. These cases highlight a potential complication that may not be readily appreciated by clinicians who routinely perform femoral vascular cannulation. After all evidence of ongoing infection had disappeared, both cases ultimately were treated with total hip arthroplasty. Both patients have improved function and pain at 2.5 and 5 years of follow-up. Given the frequency with which femoral intravascular catheters are used in numerous procedures, methods of avoiding infection of the hip joint must be implemented. These 2 cases emphasize the potential risks of these procedures and show management with total hip arthroplasty. Copyright 2002, Elsevier Science (USA). All rights reserved.

    Kingella kingae is part of the nonpathogenic flora normally found in the oral cavity and pharynx. Recent reports have established that K. kingae can cause invasive infections in pediatric patients. Few cases have been described in adults, however. We report a case of K. kingae arthritis of the knee followed by endocarditis in a 59-year-old woman. Physicians and microbiologists should be alert to the possibility of K. kingae infection. K. kingae is easy to detect provided its specific culture requirements are taken into account. Synovial fluid inoculation into blood culture vials considerably increases the likelihood of K. kingae recovery in patients with septic arthritis.

This organism rarely causes serious infections and has only been described in newborns and immunocompromised individuals or as a skin infection. This child developed an indolent joint swelling after a minor skin injury, and symptoms were initially thought most consistent with chronic arthritis. The case demonstrates that clinicians should consider joint infection in children presenting with acute monoarticular swelling, even without prominent systemic features. PMID:27366165

    To review the records of 50 children who underwent open joint washout for septic arthritis with (n=25) or without (n=25) preoperative antibiotics. Records of 50 children who underwent open joint washout for presumed septic arthritis with (n=25) or without (n=25) preoperative antibiotics were reviewed. 17 boys and 8 girls aged 3 weeks to 16 years (median, 1.5 years) who were prescribed preoperative antibiotics before joint washout were compared with 12 boys and 13 girls aged one month to 14 years (median, 2 years) who were not. Following arthrotomy and washout, all patients were commenced on high-dose intravenous antibiotics. Patients were followed up for 6 to 18 months until asymptomatic. Patients who were referred from places other than our emergency department were twice as likely to have been prescribed preoperative antibiotics (p=0.0032). Patients prescribed preoperative antibiotics had a longer median (range) time from symptom onset to joint washout (8 [2-23] vs. 4 [1-29] days, p=0.05) and a higher mean erythrocyte sedimentation rate (93.1 vs. 54.3 mm/h, p=0.023) at presentation. Nonetheless, the 2 groups were comparable for weight bearing status, fever, and positive culture, as well as the mean (range) duration of antibiotic treatment (4.9 [4-7] vs. 4.7 [1-8] weeks, p=0.586). Preoperative antibiotics should be avoided in the management of septic arthritis in children. Their prescription delays diagnosis and definitive surgery, and leads to additional washouts and complications. A high index of suspicion and expedite referral to a specialist paediatric orthopaedic unit is needed if septic arthritis is suspected.

    The aim of this study is to determine the epidemiological features, clinical presentation, and treatment of children with septic arthritis. A retrospective review was conducted on a total of 141 children with septic arthritis treated in Hospital Universitario La Paz (Madrid) between the years 2000 to 2013. The patient data collected included, the joint affected, the clinical presentation, the laboratory results, the appearance, Gram stain result, and the joint fluid culture, as well as the imaging tests and the treatment. Most (94%) of the patients were less than 2 years-old. The most common location was the knee (52%), followed by the hip (21%). The septic arthritis was confirmed in 53%. No type of fever was initially observed in 49% of them, and 18% had an ESR (mm/h) or CRP (mg/l) less than 30 in the initial laboratory analysis. The joint fluid was purulent in 45% and turbid in 12%. The Gram stain showed bacteria in 4%. The fluid culture was positive in 17%. Staphylococcus aureus was the most common pathogen found, followed by Streptococcus agalactiae, Streptococcus pneumoniae, and Kingella kingae. Antibiotic treatment was intravenous administration for 7 days, followed by 21 days orally. Surgery was performed in 18% of cases. The diagnosis was only confirmed in 53% of the patients. Some of the confirmed septic arthritis did not present with the classical clinical/analytical signs, demonstrating that the traumatologist or paediatrician requires a high initial level of clinical suspicion of the disease.

    Acute leukemia in children presents with various clinical manifestations that mimic orthopaedic conditions. The association of septic arthritis of the elbow with acute leukemia is very rare, and the correct diagnosis of acute leukemia is often established only after treatment of the septic arthritis. In this article, we present a three-year-old child patient with elbow septic arthritis related to acute leukemia, diagnosed promptly by bone marrow aspiration on the same day as emergency surgical debridement of the septic elbow joint due to the maintenance of a high index of suspicion, and treated with chemotherapy as soon as possible. The emergency physician and orthopaedist must recognize unusual patterns of presentation like this. Since delay in initiating treatment of septic arthritis may result in growth disturbance, elbow septic arthritis associated with pediatric acute leukemia must be treated promptly and appropriately. Early diagnosis is a good prognostic feature of childhood acute leukemia.

    Primary degenerative arthritis of the elbow is an uncommon disorder that recently has been more clearly recognized. The purpose of this study was to analyze the long-term results and complications of ulnohumeral arthroplasty as treatment of primary osteoarthritis of the elbow and to document any tendency for recurrence of the arthritis after the procedure. The results of ulnohumeral arthroplasties performed at our institution, between 1986 and 1996, in forty-six elbows (forty-five patients) with primary osteoarthritis were reviewed at an average of eighty months (range, twenty-four to 164 months) after the operation. There were forty-four men and one woman with a mean age of forty-eight years. All patients complained of pain with terminal elbow extension. The pain was associated with locking in fourteen elbows and with ulnar nerve symptoms in twelve. The surgical procedure involved fenestration of the olecranon fossa and excision of olecranon and coronoid osteophytes in all patients, with removal of loose bodies in thirty-six elbows. A capsular release was performed in nineteen elbows, and an ulnar nerve transposition or neurolysis was done in eight. Preoperative and follow-up assessment included evaluation of elbow pain and range of motion with the Mayo Elbow Performance Score. The mean arc of flexion-extension improved from 79 degrees (range, 10 degrees to 135 degrees) preoperatively to 101 degrees (range, 45 degrees to 135 degrees) at the time of follow-up (p < 0.05). At the last follow-up examination, thirty-five elbows (76%) were not painful or were only mildly painful and eleven were moderately or severely painful. According to the Mayo Elbow Performance Score, the result was excellent for twenty-six elbows, good for eight, fair for four, and poor for eight. Thirteen of the forty-five patients reported some degree of ulnar nerve symptoms postoperatively, and six of them required another operation to decompress or translocate the nerve.

    The aim of the present study was to investigate the effect of long-term infliximab treatment on various autoantibodies in patients with rheumatoid arthritis. Serum samples from 30 consecutive patients, who were prospectively followed during infliximab and methotrexate therapy for refractory rheumatoid arthritis, were tested at baseline and after 30, 54 and 78 weeks. At these points, median values of the Disease Activity Score were 6.38 (interquartile range 5.30–6.75), 3.69 (2.67–4.62), 2.9 (2.39–4.65) and 3.71 (2.62–5.06), respectively. Various autoantibodies were assessed by standard indirect immunofluorescence and/or ELISA. Initially, 50% of patients were positive for antinuclear antibodies, and this figure increased to 80% after 78 weeks (P = 0.029). A less marked, similar increase was found for IgG and IgM anticardiolipin antibody titre, whereas the frequency of anti-double-stranded DNA antibodies (by ELISA) exhibited a transient rise (up to 16.7%) at 54 weeks and dropped to 0% at 78 weeks. Antibodies to proteinase-3 and myeloperoxidase were not detected. The proportion of patients who were positive for rheumatoid factor (RF) was similar at baseline and at 78 weeks (87% and 80%, respectively). However, the median RF titre exhibited a progressive reduction from 128 IU/ml (interquartile range 47–290 IU/ml) to 53 IU/ml (18–106 IU/ml). Anti-cyclic citrullinated peptide (CCP) antibodies were found in 83% of patients before therapy; anti-CCP antibody titre significantly decreased at 30 weeks but returned to baseline thereafter. In conclusion, the presence of anti-double-stranded DNA antibodies is a transient phenomenon, despite a stable increase in antinuclear and anticardiolipin antibodies. Also, the evolution of RF titres and that of anti-CCP antibody titres differed during long-term infliximab therapy. PMID:15142273

    To investigate the effects of arthroscopic wrist synovectomy on the clinical course of rheumatoid arthritis in a large series with long-term follow-up. We performed arthroscopic synovectomy on 56 wrists in 49 patients with rheumatoid arthritis. At a mean follow-up of 7.9 years (range, 5-12 y), we evaluated pain and patient satisfaction using a visual analog scale and assessed overall function using the Mayo wrist score. Radiographic stage was graded according to Larsen stage. We determined clinical outcomes on the recurrence of wrist synovitis, which we evaluated by symptoms of pain and swelling and physical examination. Preoperative variables were statistically analyzed to find factors that could influence the results. The mean visual analog scale score for wrist pain decreased from 6.3 to 1.7, and the mean Mayo wrist score (evaluated in 39 wrists) improved from 48 (range, 5-70) to 76 (range, 55-100). The mean visual analog scale score for patient satisfaction was 7.9. At final follow-up, synovitis was controlled in 42 wrists (75%) and recurred in the others. The mean Larsen stage progressed from 2.2 to 3.3. Analysis of preoperative variables revealed no factors that significantly affected clinical outcomes in terms of sex, age, duration of wrist symptom, preoperative serologic inflammatory markers, or Larsen stage. Arthroscopic synovectomy of the wrist can provide pain relief and functional improvement with control of synovitis in 75% of rheumatoid wrists that have not responded to medication. Therapeutic IV.

    Rice body formation in a joint or bursa is a rare condition, and is usually associated with rheumatoid arthritis or tuberculous arthritis. Here we describe a case of multiple rice body formation in a shoulder joint and in adjacent bursae, which was confirmed to be due to septic arthritis by Candida species. To the best of our knowledge, rice body formation in Candida septic arthritis in an immune-competent patient has not been previously reported.

    Septic arthritis of the sternoclavicular joint (SCJ) is an atypical and rarely seen clinical condition. The prognosis for patients with SCJ septic arthritis is often poor. The objective of this study was to compare clinical characteristics between SCJ and non-sternoclavicular joint (NSCJ) septic arthritis and to identify independent risk factors for SCJ septic arthritis. A total of 450 adult patients diagnosed with septic arthritis during the January 2002 to December 2013 study period were included in this retrospective cohort study. Patient characteristics, clinical manifestations, and treatment outcomes were examined. Univariate and multivariate analysis was performed to identify potential risk factors for SCJ septic arthritis. Thirty-three (7.3%) of 450 patients had SCJ septic arthritis and the remaining 417 patients had NSCJ. Oligoarthritis or polyarthritis were seen more often in SCJ patients than in NSCJ patients (55 vs. 19%; p < 0.05). Abscess formation and bacteremia were more commonly found at presentation in the SCJ group than in the NSCJ group (18 vs. 8%; p < 0.05 for abscess formation; and, 53.1 vs. 26.6%; p < 0.05 for bacteremia). In multivariate analysis, extra-articular infection (OR 2.7, 95% CI 1.2-6.4; p = 0.02), cirrhosis (OR 1.9, 95% CI 1.1-3.3; p = 0.02), and malignancy (OR 3, 95% CI 1.1-7.8; p = 0.03) were independent risk factors for SCJ septic arthritis. SCJ septic arthritis is an uncommon septic arthritis that frequently presents with local and systemic complications. Factors found to be significantly associated with SCJ septic arthritis were extra-articular infection and immunocompromised host. A high index of suspicion in high-risk patients is the key to achieving improved outcomes.

    Forty-one patients with 42 joint infections were admitted to the hospital between June 1989 and June 1994. An overview on the behaviour of septic arthritis in both children and adults, at presentation and after various types of treatment was done. There were 32 knees, 7 hips, 2 elbows and 1 shoulder. Duration of symptoms, type of organism, type of joint drainage, presence of preexisting joint problems and presence of osteomyelitis are among the important factors with prognostic significance. Seventy three percent of patients with less than 7 days duration of symptoms had satisfactory results. Whereas when the duration of symptoms exceeded 7 days, 75% of the patients had unsatisfactory outcome. All cases with poor outcome had positive cultures. Staphylococcus aureus was responsible for 77% of the culture-positive cases. All Staphylococcus aureus in this study were penicillin-resistant but sensitive to cloxacillin. There were 3 instances where Staphylococcus became resistant to cloxacillin following recurrence of septic arthritis. However, they were still sensitive to third generation cephalosporin. Staphylococcus aureus was capable of producing poor results even when the case was treated early. Other organisms were gram-negative bacilli which infect patients with suppressed immune system, that is, intravenous drug abuser, systemic steroid therapy and diabetes mellitus. Open arthrotomy was the method of drainage used in all hip sepsis. This method was also the most reliable method of joint drainage in other joints compared to aspiration method when frank pus was already present. Most immuno-compromised patients recovered badly from septic arthritis. Associated adjacent osteomyelitis, preexisting chronic arthritis and recent intra-articular fractures were also noted to adversely affect the functional outcome.

    To determine the forms and characteristics of rheumatic diseases whose initial presentation mimics septic arthritis. Retrospective study of 398 patients hospitalized between 1979 and 2005 for arthritis diagnosed and treated as septic. In 10 cases, initial presentation of a rheumatic disease was highly suggestive of septic arthritis, and the patient was treated as such. Three had rheumatoid arthritis, 3 spondyloarthropathies, 2 unclassified rheumatic diseases, 1 Wegener granulomatosis and 1 cytosteatonecrosis. Mean time to diagnosis of rheumatic arthritis was 6 months. There were 7 males and 3 females aged from 15 to 77 years. Six had fever, and 3 had leucocytosis. Average ESR was 68 mm/1 h, and C-reactive protein was above 100 mg/l in 6 patients. Five patients had radiological signs suggestive of septic arthritis. Joint fluid count was above 100,000 WBCs/mm(3) in 2/5. Synovial biopsy suggested septic arthritis in 5 out of 6. These cases of pseudoseptic arthritis were indistinguishable from true septic arthritis. Follow-up is required in septic arthritis with negative culture findings to exclude rheumatic disease.

    The aims of this study are to analyse the characteristics of septic arthritis stratified by age and to identify the predictors of treatment failure and mortality in septic arthritis. A retrospective single-centre study was conducted in patients with native septic arthritis between 1994 and 2012. The primary outcome was treatment failure. Secondary outcomes included mortality, complications, endocarditis, bacteraemia, hospital readmission and the duration of the hospital stay. Logistic regression analyses with a propensity score were performed to identify the predictors of response and mortality. Additional analyses were performed according to age and the initial treatment (surgery or conservative). A total of 186 patients were studied. The median (interquartile range) age was 64 (46, 74) years, and the percentage of male patients was 68.9%. A logistic regression analysis showed that Staphylococcus aureus infection [OR 2.39 (1.20-4.77), p = 0.013], endocarditis [OR 4.74 (1.16-19.24), p = 0.029] and the involvement of joints difficult to access with needle drainage [OR 2.33 (1.06-5.11), p = 0.034] predict treatment failure and that age [OR 1.27 (1.07 = 1.50), p = 0.005], the leucocyte count at baseline [OR 1.01 (1.00-1.02), p = 0.023], bacteraemia [OR 27.66 (1.39-551.20), p = 0.030], diabetes mellitus [OR 15.33 (1.36-172.67), p = 0.027] and chronic renal failure [OR 81.27 (3.32-1990.20), p = 0.007] predict mortality. No significant differences in treatment failure by age were found. In septic arthritis, the predictors of mortality and the predictors of treatment failure differ. The predictors of treatment failure concern local factors and systemic complications, whereas conditions related to the host's immune competence, such as age and comorbidities that hamper the host's response, predict mortality.

    A 76-year-old man with a history of osteoarthritis presents with right leg erythema and inability to weight-bear and pain in his right shoulder. Synovial fluid cell count of the knee and shoulder showed abundant neutrophils, and cultures of the knee showed growth of Pasteurella multocida. The patient owned four cats with which he had frequent contact, but history and physical examination elicited no evidence of scratches or bites. This case highlights the invasive potential of Pasteurella multocida in an immunocompetent individual and its capacity to cause septic arthritis in the setting of frequent animal contact.

    Abstract There is still controversy on the management of septic arthritis in neonates. This study aims to investigate the treatment of septic arthritis in neonates. We reviewed 52 neonates (37 males and 15 females) with septic arthritis in our hospital during 2004 to 2015. The mean age at onset of infection was 17.5 ± 7.6 days, mean age at admission was 32.6 ± 10.7 days. A total of 56 joints were involved (22 knees, 18 shoulders, 13 hips, and 3 other joints). Thiryt-six patients underwent surgical drainage, 14 patients were treated nonoperatively, 2 families refused treatment. Forty-four patients (48 joints) were followed for 4.5 ± 1.2 years. Based on treatment, these 48 joints were divided into an operative group and a nonoperative group. Clinical presentations, imaging examination results, treatments, and outcomes were analyzed. Among the patients who were followed-up, the time from onset to treatment in the operatively managed group (12.7 ± 8.1 days) was significantly shorter than that in the conservatively managed group (20.0 ± 8.2 days). There were no significant differences between both groups on the age at onset, age at admission, imaging score, length of hospital stay, WBC counts, and intravenous medication time. Thirty-five sites (72.9%) recovered completely. There was no significant difference on recovery rate between operative and nonoperative group. Only 33.3% of the hips recovered, this was significantly lower than that of knee/ankle (85.0%) and shoulder/elbow (78.9%). Sequels were found in 13 joints. Logistic regression indicated that sex, imaging score, and hip joint involvement were predictors of sequel. One point of imaging score increased the risk of sequels by a factor of 2.960, and hip joint involvement increased the risk of sequels by a factor of 12.712. Females were more likely to have sequels than males. Surgical drainage is recommended for early diagnosed neonatal septic arthritis and hip infections. A conservative

    The iliacus muscle is closely associated with the psoas muscle, femoral nerve, hip joint, pelvic and intraabdominal structures; thus, its disorders may present as lower abdominal pain, hip pain, or femoral neuropathy. Iliacus pyomyositis, a primary bacterial infection of the skeletal muscle not secondary to a contiguous skin, bone, or soft-tissue infection, presenting as hip pain, femoral neuropathy, and sympathetic effusion of the hip joint in an 8-year-old boy mimicked septic arthritis of the hip joint. Computed tomography was helpful in delineating the accurate location of the lesion. Surgical drainage and appropriate antibiotic therapy led to complete resolution and full functional recovery.

    Patients with rheumatoid arthritis (RA) are at increased risk of acute coronary syndrome (ACS) and suffer from poorer short-term outcomes after ACS. The aims of this study were to assess long-term outcomes in patients with RA with ACS compared with non-RA patients with ACS, and to investigate whether the use of secondary preventive drugs could explain any differences in ACS outcome. We performed a cohort study based on 1135 patients with RA and 3184 non-RA patients who all developed an incident ACS between 2007 and 2010. We assessed 1-year and overall relative risks for ACS recurrence and mortality, as well as prescriptions of standard of care secondary preventive drugs. The risk of ACS recurrence, and of mortality, was increased in RA, both at 1 year after adjusting for baseline comorbidities (HR=1.30(95% CI 1.04 to 1.62) and 1.38(95% CI 1.20 to 1.59), respectively) and throughout the complete (mean 2 years) follow-up (HR=1.27(95% CI 1.06 to 1.52) and 1.50(95% CI 1.34 to 1.68), respectively). Among certain subgroups of ACS, there was a tendency of lower usage of statins, whereas there were no apparent differences in others. The increased rates of ACS recurrence and mortality remained in subgroup analyses of individuals whose prescription pattern indicated both adequate initiation and persistence to secondary preventive treatments. Patients with RA suffer from an increased risk of ACS recurrence and of death following ACS compared with general population, which in the present study could not readily be explained by differences in usage of secondary preventive drugs. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To assess the ability of mid infrared deported spectroscopy to discriminate synovial fluids samples of septic arthritis patients from other causes of joint effusion. Synovial fluids obtained from patients with clinically suspected arthritis were collected, analysed and classified according to standard diagnostic procedures as septic or non-septic. A spectroscopic analysis on synovial fluid samples was then performed using a coiled optical fiber made with chalcogenide glass. After a factorial analysis of the normalized spectra and the computation of a Fisher test used to select the most relevant components, a logistic regression model was fitted, allowing to attribute a score between 0 - non-septic -, and 1 - septic. In a first phase, we analysed the synovial fluids from 122 different synovial fluids including 6 septic arthritis among arthritis of various origins. Septic synovial fluids were identified with a sensitivity of 95.8% and a specificity of 93.9% and an AUROC of 0.977. The analysis of an independent set of samples (n=42, including two septic arthritis) gave similar values. Our data strongly supports the interest of mid infrared deported spectroscopy, which could be used potentially at point of care, for a rapid and easy diagnosis of septic arthritis. Now, the precision of the diagnosis must be evaluated through a multicentric study on a larger panel of patients. Copyright © 2015 Société française de rhumatologie. Published by Elsevier SAS.

    1991-01-01

    In order to describe the features of septic arthritis (SA) in patients with connective tissue diseases (CTDs), a series of 17 CTD cases with SA episodes were studied retrospectively. The most common CTDs were systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Involvement was oligoarticular in 64% of cases and mono-articular in the remainder. Clinical, radiological and laboratory findings proved insufficient to allow differential diagnosis between SA and an underlying arthritic flare-up, which could only be carried out by bacterial isolation from synovial fluid. The most frequent etiological agent was Staphylococcus aureus (Table 1). Throughout, patients were treated by needle drainage together with antibiotics, first by parenteral (average 17 days) and later by oral route (average 46 days). Cases with greater diagnostic delay and initiation of therapy were those requiring arthrotomy and those who presented more complications mainly osteomyelitis and permanent disability (Table 2).

    Background As long-term treatment with antitumour necrosis factor (TNF) drugs becomes accepted practice, the risk assessment requires an understanding of anti-TNF long-term safety. Registry safety data in rheumatoid arthritis (RA) are available, but these patients may not be monitored as closely as patients in a clinical trial. Cross-indication safety reviews of available anti-TNF agents are limited. Objective To analyse the long-term safety of adalimumab treatment. Methods This analysis included 23 458 patients exposed to adalimumab in 71 global clinical trials in RA, juvenile idiopathic arthritis, ankylosing spondylitis (AS), psoriatic arthritis, psoriasis (Ps) and Crohn's disease (CD). Events per 100 patient-years were calculated using events reported after the first dose through 70 days after the last dose. Standardised incidence rates for malignancies were calculated using a National Cancer Institute database. Standardised death rates were calculated using WHO data. Results The most frequently reported serious adverse events across indications were infections with greatest incidence in RA and CD trials. Overall malignancy rates for adalimumab-treated patients were as expected for the general population; the incidence of lymphoma was increased in patients with RA, but within the range expected in RA without anti-TNF therapy; non-melanoma skin cancer incidence was raised in RA, Ps and CD. In all indications, death rates were lower than, or equivalent to, those expected in the general population. Conclusions Analysis of adverse events of interest through nearly 12 years of adalimumab exposure in clinical trials across indications demonstrated individual differences in rates by disease populations, no new safety signals and a safety profile consistent with known information about the anti-TNF class.

    The purpose of this study was to identify factors influencing long-term adherence to aquatic exercise in older women with arthritis. Participants (n = 72) completed an educational program on aquatic exercise and underwent follow up for 6 months. At follow-up, women who continued aquatic exercise (adherence group, n = 25) had significantly higher scores than women in the nonadherence group (n = 47) in exercise self-efficacy (p < 0.0001) and group cohesion based on social aspects (p = 0.009). Both groups reported experiencing similar barriers to exercise (rho = 0.78). The findings provide insights for the development of strategies to promote long-term adherence to this type of aquatic exercise. Specifically, the findings encourage the fostering of exercise self-efficacy and social group cohesion during participation in educational programs to increase long-term exercise adherence.

    The aim of the study was to assess the role of the complement system in Staphylococcus aureus arthritis and septicaemia. The murine model of haematogenously acquired septic arthritis was used, injecting intravenously toxic shock syndrome toxin-1 (TSST-1), producing S. aureus LS-1. Complement was depleted using cobra venom factor (CVF). Evaluation of arthritis was performed clinically and histopathologically. In addition, the effect of complement depletion on the phagocytic activity of leucocytes was assessed in vivo and in vitro. Six days after inoculation of S. aureus the prevalence of arthritis in decomplemented mice was three-fold higher than that in controls (91% versus 25%). The clinical severity of arthritis at the end of the experiment, expressed as arthritic index, was 7.3 and 1.9, respectively. These findings were confirmed by histological index of synovitis as well as of cartilage and/or bone destruction being significantly higher in decomplemented mice than in controls (9.8 ± 1.7 versus 4.9 ± 1.2, P < 0.05; and 7.9 ± 1.7 versus 3.0 ± 0.9, P < 0.05, respectively). Also, the septicaemia-induced mortality was clearly higher in decomplemented mice compared with the controls. CVF treatment significantly reduced in vivo polymorphonuclear cell-dependent inflammation induced by subcutaneous injection of olive oil and mirroring the capacity of polymorphonuclear cells (PMNC) to migrate and/or extravasate. Besides, the decomplementation procedure significantly impaired phagocytic activity of peripheral blood leucocytes in vitro, since the number of phagocytes being able to ingest bacteria decreased by 50% when the cells were maintained in decomplemented serum compared with those in intact serum. The conclusion is that complement depletion aggravates the clinical course of S. aureus arthritis and septicaemia, possibly by a combination of decreased migration/extravasation of PMNC and an impairment of phagocytosis.

    Identification and interpretation of pathologies in the fossil record allows for unique insights into the life histories of extinct organisms. However, the rarity of such finds limits not only the sample size for palaeopathologic studies, but also the types of analyses that may be performed. In this study, we present the first occurrence of a palaeopathology in a vertebrate from the Mesozoic of the East Coast of North America (Appalachia), a pathologic ulna and radius of an indeterminate hadrosaur from the Navesink Formation (New Jersey). X-ray microtomography allowed for both detailed and more accurate diagnosis of the pathologic condition as well as virtual conservation of the specimen. Based on extant archosaurian comparisons, the hadrosaur was diagnosed with severe septic arthritis affecting the proximal ulna and radius. Diagnosis was based on erosion of the joint and highly reactive periosteal bone growth and fusion of the elements. To the best of our knowledge, this is the first recorded account of septic arthritis in dinosaurs. The severity of the pathology suggests the animal suffered with this condition for some time before death. Unfortunately, only the ulna and radius were found. Thus, the extent to which the condition spread to other parts of the body is unknown.

    Parvimonas micra is a fastidious, anaerobic, gram positive coccus, which is found in normal human oral and gastrointestinal flora. It has also been known as Peptostreptococcus micros and Micromonas micros with its most recent re-classification in 2006. It has been described in association with hematogenous seeding of prosthetic joints [1,2]. Several cases of discitis and osteomyelitis have been described in association with dental procedures and periodontal disease often with a subacute presentation. However, cases of native joint septic arthritis are limited [3-5]. Per our literature review, there is one case of native knee septic arthritis described in 1999, with a prolonged time to diagnosis and treatment due to difficulty culturing P. micra. The previously reported patient experienced significant joint destruction and morbidity [6]. Advances in culture techniques and new methods of organism identification including MALDI-TOF and 16s rRNA sequencing have lead to increased identification of this organism, which may be a more frequent bone and joint pathogen than previously realized.

    An improved method of lactic acid estimation by gas liquid chromatography (GLC) is described. Synovial fluid lactic acid estimation was performed on 52 patients (15 with septic arthritis and 37 with non-septic arthropathies) and compared to routine microbiological methods and white cell counts. Lactic acid was found to be a useful and rapid test for differentiating between septic and non-septic arthritis being markedly raised (greater than 12 mmol/l) in all the septic joints. Raised lactic acid concentrations were of particular diagnostic value in patients in whom antibiotic therapy had commenced before joint aspiration. The results of lactic acid estimation on sequential samples were helpful in assessing the response of septic arthritis to treatment. PMID:7076866

    Septic arthritis has to be suspected in children with joint effusion and fever so as to perform joint aspiration, which will confirm the diagnosis by bacteriological methods, and to perform surgical treatment by joint lavage. Since development of current molecular methods, such as real-time PCR, Kingella kingae has become the first microbial agent of osteoarticular infections in young children, whereas Staphylococcus aureus is second. C-reactive protein (CRP) is an aid used to diagnose septic arthritis, but its elevation could be moderate. In a previous study, conducted at our hospital, 10% of children hospitalized for S. aureus or K. kingae septic arthritis had a CRP level<10 mg/L. To determine if diagnosis of septic arthritis could be made by other parameters, we analyzed the clinical and biologic features of these patients and compared them to those of children hospitalized for septic arthritis with initial CRP ≥10 mg/L. Among the 89 children with septic arthritis, 10% (n=9) had initial CRP<10 mg/L (K. kingae, n=5/63 ; S. aureus, n=4/26). Initial temperature and fibrinogen were significantly lower in the CRP<10 mg/L group than in the other (37.3°C vs. 37.9°C, P=0.039 and 4.19 vs. 5.72 g/L, P=0.003, respectively). Age, symptom duration before diagnosis, as well as leukocyte and platelet counts were similar in both groups. Two children (2/89=2.2%) with S. aureus septic arthritis had no fever, CRP elevation, or fibrinogen elevation. In the CRP-negative group, three of four children with S. aureus arthritis and one of five with K. kingae arthritis had a high CRP level (34, 40, 61, and 13 mg/L, respectively) 3 days after surgery and antibiotic treatment. One child with K. kingae septic arthritis and initial CRP<10 mg/L needed a second surgical drainage because of relapse of arthritis. In the S. aureus arthritis group, none of the children with initial CRP<10 mg/L experienced complications, while six of those with initial CRP≥10 mg/L needed a second surgical act

    Background Permanent joint dysfunction due to bone destruction occurs in up to 50% of patients with septic arthritis. Recently, imaging technologies such as micro computed tomography (μCT) scan have been widely used for preclinical models of autoimmune joint disorders. However, the radiological features of septic arthritis in mice are still largely unknown. Methods NMRI mice were intravenously or intra-articularly inoculated with S. aureus Newman or LS-1 strain. The radiological and clinical signs of septic arthritis were followed for 10 days using μCT. We assessed the correlations between joint radiological changes and clinical signs, histological changes, and serum levels of cytokines. Results On days 5–7 after intravenous infection, bone destruction verified by μCT became evident in most of the infected joints. Radiological signs of bone destruction were dependent on the bacterial dose. The site most commonly affected by septic arthritis was the distal femur in knees. The bone destruction detected by μCT was positively correlated with histological changes in both local and hematogenous septic arthritis. The serum levels of IL-6 were significantly correlated with the severity of joint destruction. Conclusion μCT is a sensitive method for monitoring disease progression and determining the severity of bone destruction in a mouse model of septic arthritis. IL-6 may be used as a biomarker for bone destruction in septic arthritis. PMID:28152087

    Kingella kingae is a Gram-negative rod most often recognized as 1 of the organisms causing septic arthritis and osteomyelitis in children. Infection caused by K. kingae had not been diagnosed in Iceland until 5 cases were diagnosed at the Paediatric Department at the University Hospital of Iceland over a 1 year period. In this report we describe these 5 children with invasive infection caused by K. kingae (2 with septic arthritis, 1 with osteomyelitis, 1 with septic arthritis and osteomyelitis, and 1 with bacteraemia) and review the literature. All bacterial isolates were identified by the Bactec culture system.

    We herein report the first case of septic arthritis caused by rmpA-positive hypermucoviscous community-acquired K. pneumoniae that followed urosepsis in a 65-year-old Japanese woman. The patient responded well to drainage of the abscesses and treatment with cefazolin. Although this virulent phenotype of K. pneumoniae has been primarily reported in Hong Kong, we confirmed that 18/50 isolates obtained in our hospital over the past five years displayed the hypermucoviscous phenotype. Therefore, clinicians should consider the possibility of an increasing prevalence of rmpA-positive hypermucoviscous K. pneumoniae infection in Japan and be particularly vigilant for invasive clinical manifestations, even in patients with urinary tract infections.

    Aspergillus septic arthritis is a rare and serious medical and surgical problem. It occurs mainly in immunocompromised patients. Aspergillus fumigatus is the most common causative organism followed by Aspergillus flavus. The most common site affected is knee followed by shoulder, ankle, wrist, hip and sacroiliac joint. Debridement and voriconazole are primary treatment of articular aspergilosis. To the best of our knowledge, there are no reported cases of co-infection of tuberculosis (TB) and Aspergillus infecting joints. We report a case of co-infection of TB and A. flavus of hip and knee of a 60-year-old male, with type 2 diabetes mellitus. He was treated with debridement, intravenous voriconazole, and antitubercular drugs. PMID:27293296

    Despite controversy over its exact role, radionuclide imaging plays an important role in the evaluation of patients suspected of having osteomyelitis. The differentiation between osteomyelitis and cellulitis is best accomplished by using a three-phase technique using Tc-99m methylene diphosphonate (MDP). Frequently, it is necessary to obtain multiple projections and magnification views to adequately assess suspected areas. It is recommended that a Ga-67 or In-111 leukocyte scan be performed in those cases where osteomyelitis is strongly suspected clinically and the routine bone scan is equivocal or normal. Repeated bone scan after 48 to 72 h may demonstrate increased radioactivity in the case of early osteomyelitis with the initial photon-deficient lesion. In-111 leukocyte imaging is useful for the evaluation of suspected osteomyelitis complicating recent fracture or operation, but must be used in conjunction with clinical and radiographic correlation. The recognition of certain imaging patterns appears helpful to separate osteomyelitis from septic arthritis or cellulitis. 83 references.

    Mycoplasmas, including Ureaplasma and Mycoplasma species, are uncommon but important causes of septic arthritis, especially affecting immunosuppressed patients. Many of the reported cases have been associated with congenital immunodeficiency disorders, especially hypogammaglobulinemia. Mycoplasmas are difficult to grow in the laboratory, and these infections may be underdiagnosed using culture techniques. We report a case of a 21-year-old woman with juvenile idiopathic arthritis and hip arthroplasties treated with rituximab and adalimumab who developed urogenital infections and soft tissue abscesses followed by knee arthritis with negative routine cultures. Ureaplasma species was identified from synovial fluid on 2 separate occasions using a broad-range 16S ribosomal RNA gene polymerase chain reaction. Azithromycin led to rapid improvement in symptoms, but after completion of therapy, involvement of the hip prosthesis became apparent, and again, 16S rRNA gene polymerase chain reaction was positive for Ureaplasma species. The literature is reviewed with a discussion of risk factors for Mycoplasma septic arthritis, clinical presentation, methods of diagnosis, and treatment.

Patient was using tacrolimus 1mg q.12hours. This patient started to have pain in left foot and ankle and had one episode of fever 3 days before hospital admission. Physical Examination showed weight 17kg, height 109cm, temperature 36,4°C, with pain, swelling and heat in the left ankle, without other clinical signs. Initial tests: hemoglobin 11,7g/dL hematocrit 36.4%, leukocyte count 17600/uL (7% banded neutrophils, 70% segmented neutrophils, 2% eosinophils, basophils 1%, 13% lymphocytes, 7% monocytes) C-reactive protein 170,88mg/L. Joint ultrasound showed moderate effusion in the site. Patient was submitted to surgical procedure and S. multivorum was isolated from the effusion. The germ was susceptible to broad spectrum cephalosporins (ceftriaxone and cefepime) and fluoroquinolones (ciprofloxacin and levofloxacin), and it was resistant to carbapenemic antibiotics and aminoglycosides. He was treated intravenously with oxacillin for 15 days and ceftriaxone for 13 days, and orally with ciprofloxacin for 15 days, with good outcome. The Sphingobacterium multivorum is a gram negative bacillus that belongs to Flavobacteriaceae family and it is considered non-pathogenic. It has rarely been described as a cause of infections in humans, especially in hospital environment and in immunosuppressed patients.

    Septic arthritis of the acromioclavicular (AC) joint is a rare entity with symptoms that include erythema, swelling, and tenderness over the AC joint, fever, and limitation of shoulder motion with pain. In previous reports, Staphylococcus and Streptococcus species have been mentioned as common causative organisms. Haemophilus parainfluenzae is a normal inhabitant of the oral cavity, respiratory tract, gastrointestinal tract, and urogenital tract. However, it sometimes causes opportunistic infections leading to septic arthritis and osteomyelitis. AC joint infection associated with H.parainfluenzae is very rare, and only one case has been reported in the literature. Moreover, septic arthritis in immunocompetent patients is also very rare. Here, we report the case of a healthy patient with H. parainfluenzae-related septic arthritis of the AC joint.

    Septic arthritis and gout are major diseases that should be suspected in patients with acute monoarthritis. These two diseases are clinically similar and often indistinguishable without the help of synovial fluid analysis. Recently, a novel diagnostic rule for gout without synovial fluid analysis was developed and showed relevant performances. This study aimed to determine whether this diagnostic rule could perform well in distinguishing gout from septic arthritis. The diagnostic rule comprises 7 clinical and laboratory variables, each of which is given a specified score. The probability of gout is classified into 3 groups according to the sum of the scores: high (≥ 8), intermediate (> 4 to < 8) and low probability (≤ 4). In this retrospective study, we applied this diagnostic rule to 136 patients who presented as acute monoarthritis and were subsequently diagnosed as acute gout (n = 82) and septic arthritis (n = 54) based on synovial fluid analysis. The mean sum of scores of acute gout patients was significantly higher than that of those with septic arthritis (8.6 ± 0.2 vs. 3.6 ± 0.32, P < 0.001). Patients with acute gout had significantly more 'high', and less 'low' probabilities compared to those with septic arthritis (Eta[η]: 0.776). The prevalence of acute gouty arthritis, as confirmed by the presence of monosodium crystal, was 95.5% (61/64), 57.5% (19/33), and 5.1% (2/39) in high, intermediate and low probability group, respectively. The recently introduced diagnostic rule properly discriminates acute gout from septic arthritis. It may help physicians diagnose gout in cases difficult to be differentiated from septic arthritis.

    Introduction Magnetic resonance (MR) arthrogram is a commonly used investigation tool to detect various pathologies in the shoulder. The complications following this procedure is minor and rare. Septic arthritis is one of the rare complications which can develop after MR arthrogram. We report a case of secondary frozen shoulder after MR arthrogram induced septic arthritis. Presentation of case A young, fit and well female patient underwent MR arthrogram to detect any labral tears. Two days following the procedure, she developed signs and symptoms suggestive of septic arthritis of the shoulder. The patient underwent repeated arthroscopic debridement and washout. The organisms isolated was Staphylococcus epidermidis. She was treated with six weeks of intravenous antibiotics. The patient developed stiffness of the shoulder due to secondary frozen shoulder which was treated with arthroscopic capsular release with good functional outcomes at three months. Discussion MR arthrogram is a rare cause of septic arthritis of the shoulder. The common method introducing the organisms is from the skin flora or contaminated arthrogram trays. The treatment is repeated arthroscopic washouts and six weeks of appropriate intravenous antibiotics. Residual pain, stiffness and chondrolysis are common sequelae of septic arthritis. Conclusion Septic arthritis is a recognised and rare complication of MR arthrogram. Early and prompt diagnosis with arthroscopic washout and debridement combined with intravenous antibiotics helps to eradicate the infection. Secondary frozen shoulder is a late complication of sepsis in the joint. PMID:25884758

    Rapid diagnosis of septic arthritis from Gram-stain microscopy is limited by an inherent false-negative rate of 25-78%. The presence of concomitant crystal arthritis in 5% of cases represents a particular diagnostic challenge. This study aims to investigate the effects that a concomitant crystal arthropathy have on the ability of Gram-stain microscopy of synovial fluid to diagnose a septic arthritis. This is a 12-year retrospective cohort study. Inclusion criteria were a positive synovial fluid culture result with a positive clinical diagnosis of septic arthritis. Results were correlated with presence or absence of urate and calcium pyrophosphate crystals, and Gram-stain result. During this time our collection and analysis methods remained unchanged. All samples were collected in Lithium Heparin containers. Chi-squared test with a p value < 0.05 was considered significant. 602 synovial fluid samples were included. 162 cases of concomitant crystal arthritis were identified (27%). Of these, 16 (10%) had an initial negative Gram-stain. Of the 440 samples with no crystals detected, 18 (4%) had an initial negative Gram-stain microscopy result (p < 0.05). The incidence of concurrent septic and crystal arthritis may be higher than previously thought. Synovial fluid samples in concomitant septic and crystal arthritis are significantly less likely to have a positive Gram-stain at microscopy than in cases of an isolated septic arthritis. We would advise the clinician to maintain a high index of suspicion for septic arthritis in these patients.

    Differentiating between septic arthritis and Lyme disease of the knee in endemic areas can be challenging and has major implications for patient management. The purpose of this study was to identify a prediction rule to differentiate septic arthritis from Lyme disease in children presenting with knee pain and effusion. We retrospectively reviewed the records of patients younger than 18 years of age with knee effusions who underwent arthrocentesis at our institution from 2005 to 2013. Patients with either septic arthritis (positive joint fluid culture or synovial white blood-cell count of >60,000 white blood cells/mm(3) with negative Lyme titer) or Lyme disease (positive Lyme immunoglobulin G on Western blot analysis) were included. To avoid misclassification bias, undiagnosed knee effusions and joints with both a positive culture and positive Lyme titers were excluded. Historical, clinical, and laboratory data were compared between groups to identify variables for comparison. Binary logistic regression analysis was used to identify independent predictive variables. One hundred and eighty-nine patients were studied: 23 with culture-positive septic arthritis, 26 with culture-negative septic arthritis, and 140 with Lyme disease. Multivariate binary logistic regression identified pain with short arc motion, history of fever reported by the patient or a family member, C-reactive protein of >4 mg/L, and age younger than 2 years as independent predictive factors for septic arthritis. A simpler model was developed that showed that the risk of septic arthritis with none of these factors was 2%, with 1 of these factors was 18%, with 2 of these factors was 45%, with 3 of these factors was 84%, or with all 4 of these factors was 100%. Although septic arthritis of the knee and Lyme monoarthritis share common features that can make them difficult to distinguish clinically, the presence of pain with short arc motion, C-reactive protein of >4.0 mg/L, patient-reported history of

    We describe a 53-year-old alcoholic man who presented with hip septic arthritis due to Bacteroides fragilis. This arthritis involved a severe destruction of the femoral head, which was completely devitalized. Recovery was achieved after 4 months of antimicrobial therapy with imipenem/cilastatin plus metronidazole, surgical debridement of the necrotic tissues and four sessions of hyperbaric oxygen.

    Background Interleukin-1 receptor antagonist (IL-1Ra) is the primary therapy against autoinflammatory syndromes with robust efficacy in reducing systemic inflammation and associated organ injury. However, patients receiving IL-1Ra might be at increased risk of acquiring serious infections. Aims To study whether IL-1Ra treatment deteriorates Staphylococcus aureus (S. aureus) septic arthritis and sepsis in mice. Method NMRI mice were treated with anakinra (IL-1Ra) daily for 7 days before intravenous inoculation with S. aureus strain Newman in both arthritogenic and lethal doses. The clinical course of septic arthritis, histopathological and radiological changes of the joints, as well as the mortality were compared between IL-1Ra treated and control groups. Results IL-1Ra treated mice developed more frequent and severe clinical septic arthritis. Also, the frequency of polyarthritis was significantly higher in the mice receiving IL-1Ra therapy. In line with the data from clinical arthritis, both histological and radiological signs of septic arthritis were more pronounced in IL-1Ra treated group compared to controls. Importantly, the mortality of IL-1Ra treated mice was significantly higher than PBS treated controls. Conclusion IL-1Ra treatment significantly aggravated S. aureus induced septic arthritis and increased the mortality in these mice. PMID:26135738

  16. Post-arthroscopy septic arthritis: Current data and practical recommendations.

    Septic arthritis develops after less than 1% of all arthroscopy procedures. The clinical symptoms may resemble those seen after uncomplicated arthroscopy, raising diagnostic challenges. The diagnosis rests on emergent joint aspiration with microscopic smear examination and prolonged culturing on specific media. Urgent therapeutic measures must be taken, including abundant arthroscopic lavage, synovectomy, and the concomitant administration of two effective antibiotics for at least 6 weeks. Preservation of implants or transplants is increasingly accepted, and repeated joint lavage is a component of the treatment strategy. After knee arthroscopy, infection is the most common complication; most cases occur after cruciate ligament reconstruction, and staphylococci are the predominant causative organisms. Emergent synovectomy with transplant preservation and appropriate antibiotic therapy ensures eradication of the infection in 85% of cases, with no adverse effect on final functional outcomes. After shoulder arthroscopy, infection is 10 times less common than neurological complications and occurs mainly after rotator cuff repair procedures; the diagnosis may be difficult and delayed if Propionibacterium acnes is the causative organism. The update presented here is based on both a literature review and a practice survey. The findings have been used to develop practical recommendations aimed at improving the management of post-arthroscopy infections, which are exceedingly rare but can induce devastating functional impairments.

    To describe the history, clinical features and microorganisms involved in a group of adult subjects with and without septic arthritis (SA) at a tertiary care in Mexico. A cross-sectional descriptive study was conducted on 96 adults with clinical suspicion of AS in one or more joints. In all cases synovial fluid arthrocentesis and culture was performed. The comparison group subjects were culture negative. A descriptive statistical analysis and binary logistic regression model was performed between the variables associated with the development of AS. A value of P≤.05 was significant. A total of 49 out of 96 subjects had a positive culture, mostly of the monoarticular type (96%; P=.02). The knee was the most common site (61%; P=.06) and pain was the main clinical manifestation (59%; P=.001). Staphylococcus was the most common etiological agent (65%; P<.001). The risk factors revealed in the final regression model were SA the history of joint disease (OR=25; P=.03) and volume increase (OR=13.16; P=.06). Functional limitation (OR=8.54; P=.04) showed a significant risk among borderline for SA. Our results are consistent with previous studies, and can be generalized to geographical areas with similar clinical features to those observed in this study.

  18. Septic arthritis: a unique complication of nasal septal abscess.

    Olsen, Steven M; Koch, Cody A; Ekbom, Dale C

    2015-03-01

    Nasal septal abscesses (NSAs) occur between the mucoperichondrium and the nasal septum. They most often arise when an untreated septal hematoma becomes infected. The most commonly reported sequela is a loss of septal cartilage support, which can result in a nasal deformity. Other sequelae include potentially life-threatening conditions such as meningitis, cavernous sinus thrombosis, brain abscess, and subarachnoid empyema. We report the case of a 17-year-old boy who developed an NSA after he had been struck in the face with a basketball. He presented to his primary care physician 5 days after the injury and again the next day, but his condition was not correctly diagnosed. Finally, 7 days after his injury, he presented to an emergency department with more serious symptoms, and he was correctly diagnosed with NSA. He was admitted to the intensive care unit, and he remained hospitalized for 6 days. Among the abscess sequelae he experienced was septic arthritis, which has heretofore not been reported as a complication of NSA. He responded well to appropriate treatment, although he lost a considerable amount of septal cartilage. He was discharged home on intravenous antibiotic therapy, and his condition improved. Reconstruction of the nasal septum will likely need to be pursued in the future.

    Total lymphoid irradiation was administered to 32 patients with intractable rheumatoid arthritis. Twenty-four patients showed at least a 25% improvement in 3 of 4 disease activity parameters, which persisted during the followup period of up to 48 months. Eight of the 32 patients required adjunctive immunosuppressive drug therapy to maintain improvement. Four patients died after total lymphoid irradiation; the causes of death were acute myocardial infarction (1 patient), pulmonary embolism (1 patient), and rheumatoid lung disease complicated by respiratory infection (2 patients). After therapy, patients exhibited a prolonged reduction in the number and function of circulating T helper cells.

    Agranulocytosis is a rare and little-known side effect of hydroxychloroquine use. This report describes the case of a 71-year-old woman with poorly controlled rheumatoid arthritis who developed agranulocytosis after several months of hydroxychloroquine therapy. She had been on several different disease-modifying antirheumatic drugs, including methotrexate and leflunomide, for her rheumatoid arthritis. Treatment became complicated following a diagnosis of leflunomide-induced pulmonary fibrosis that was discovered after an intensive care unit (ICU) admission for severe Pseudomonas pneumonia. All treatment was stopped apart from steroids and hydroxychloroquine. Because of persistent disabling symptoms, rituximab infusions were given, which improved the disease control. A second admission occurred after a routine blood test revealed agranulocytosis. Hydroxychloroquine was stopped, and after 24 h, she was discharged home. Blood counts returned to normal within 2 weeks of hydroxychloroquine cessation; hence, after the review of investigations, a diagnosis of hydroxychloroquine-induced agranulocytosis was made. This report considers current literature on hydroxychloroquine-induced agranulocytosis and explores the potential causes for this occurrence.

    Legionella spp. are an important cause of pulmonary and rarely extrapulmonary infections. L. cincinnatiensis has only been implicated in five cases to date. We herein report the first case of L. cincinnatiensis septic arthritis in a 90-year old lady with a past medical history of chronic kidney disease. She developed septic arthritis of her left wrist after having received intraarticular corticosteroid injections and oral corticosteroids administered for presumed chondrocalcinosis. Appropriate antimicrobial treatment of L. cincinnatiensis septic arthritis was delayed until identification of this organism in joint biopsies by broad-range bacterial PCR targeting the 16S rRNA gene with subsequent rDNA sequence analysis and by culture on special media. Reviewing all reported cases of septic arthritis caused by Legionella spp. other than L. cincinnatiensis it is notable that diagnosis was established by PCR in the majority of cases and only subsequently confirmed by special culture. Although most patients were immunosuppressed, outcome was favourable. Treatment consisted of a fluoroquinolone alone or in combination with rifampicin or a macrolide. Our case highlights the need for a high index of suspicion for infections with unusual/fastidious organisms when symptoms are suggestive of septic arthritis but conventional methods fail to identify a causative organism.

    The most common microorganisms isolated from septic arthritis are Staphylococcus aureus and streptoccocci. Septic arthritis due to Salmonella spp. are rare and the most commonly isolated species are S.Choleraesuis and S.Typhimurium. However the number of septic arthritis cases due to S.Typhi is low in literature. In this report, septic arthritis of hip due to S.Typhi in a multiple sclerosis patient who was under steroid therapy, was presented. A 25-year-old female patient was admitted to our clinic with the complaints of fever, left hip pain, standing and walking disability for 10 days. Her anamnesis revealed that she had had a multiple sclerosis attack and underwent triple pulse steroid therapy. Laboratory findings were as follows; WBC count: 16.300/mm3 (70% polymorphonuclear leukocyte), hemoglobin: 10.6 g/dl, erythrocyte sedimentation rate: 140 mm/hour, CRP: 28.7 g/L, AST: 86 U/L and ALT: 77 U/L. In lumbosacral magnetic resonance imaging, trochanteric bursitis and generalized myositis were detected in left hip joint compatible with septic arthritis. S.Typhi was isolated from patient's blood and operational tissue samples. Serum Salmonella TO and TH titers were found as 1/400 and 1/200, respectively. Antibiotic susceptibility test was performed by disk diffusion method, and the isolate was found susceptible to ampicillin, chloramphenicol, ceftriaxone, ciprofloxacin and trimethoprim-sulphametoxazole. The patient was treated by surgery and also by two weeks parenteral (2 x 400 mg) and 6 weeks oral (2 x 500 mg) ciprofloxacin treatment. Six months follow-up of the patient revealed that clinical, radiological and laboratory findings were normal. As far as the national literature was considered, this was the first S.Typhi septic arthritis case involving the hip joint and demonstrating bacterial growth both in blood and operational tissue. The presentation of the infection as arthritis plus diffuse myositis and bursitis, is also noteworthy.

    We assessed the predefined long-term outcomes in patients randomised in the Transfusion Requirements in Septic Shock (TRISS) trial. In 32 Scandinavian ICUs, we randomised 1005 patients with septic shock and haemoglobin of 9 g/dl or less to receive single units of leuko-reduced red cells when haemoglobin level was 7 g/dl or less (lower threshold) or 9 g/dl or less (higher threshold) during ICU stay. We assessed mortality rates 1 year after randomisation and again in all patients at time of longest follow-up in the intention-to-treat population (n = 998) and health-related quality of life (HRQoL) 1 year after randomisation in the Danish patients only (n = 777). Mortality rates in the lower- versus higher-threshold group at 1 year were 53.5 % (268/501 patients) versus 54.6 % (271/496) [relative risk 0.97; 95 % confidence interval (CI) 0.85-1.09; P = 0.62]; at longest follow-up (median 21 months), they were 56.7 % (284/501) versus 61.0 % (302/495) (hazard ratio 0.88; 95 % CI 0.75-1.03; P = 0.12). We obtained HRQoL data at 1 year in 629 of the 777 (81 %) Danish patients, and mean differences between the lower- and higher-threshold group in scores of physical HRQoL were 0.4 (95 % CI -2.4 to 3.1; P = 0.79) and in mental HRQoL 0.5 (95 % CI -3.1 to 4.0; P = 0.79). Long-term mortality rates and HRQoL did not differ in patients with septic shock and anaemia who were transfused at a haemoglobin threshold of 7 g/dl versus a threshold of 9 g/dl. We may reject a more than 3 % increased hazard of death in the lower- versus higher-threshold group at the time of longest follow-up.

    The authors present the case of a 43-year-old male who presented at the emergency department, with a mean arterial pressure of 48 mm of Hg, a sinus tachycardia of 142/min and shallow breathing at 30/min. Two days previously, he started a high-grade fever with a concomitant reddish and painful left knee and right elbow, without any treatment. Septic shock was diagnosed and the patient was started on empiric antibiotics combining ceftriaxone and vancomycin and vasopressors (norepinephrine). The painful knee and elbow joints were aspirated and cultures grew Streptococcus pneumoniae. The patient’s clinical condition improved progressively and after investigation, the diagnosis of multiple myeloma was concluded. Pneumococcal septic arthritis, an extraordinary cause of septic arthritis, is a manifestation of an underlying disease and can be responsible for septic shock. Its diagnosis should direct further investigations. It can occur in patients with joint disease but should emphasise the search of systemic immunosuppression. PMID:22694889

  7. Dose refinements in long-term therapy of rheumatoid arthritis with antimalarials.

    No eye disease was detected in over 900 rheumatoid arthritis patients treated with less than 4.0 mg/kg per day of chloroquine or less than 6.5 mg/kg per day of hydroxychloroquine for a mean of about seven years. I therefore consider these dosage rates safe, since they are below the threshold of retinal toxicity. This is based on more than 6,000 patient-years of drug exposure. That dosage threshold for retinopathy appears to be 5.1 mg/kg per day for chloroquine and 7.8 mg/kg per day for hydroxychloroquine according to my studies with these compounds. The daily dosage rate, rather than total drug accumulation, seems to determine the development of eye disease. To prevent overdosage, dosing should be calculated not on the actual weight of the patient but on ideal (lean) body weight. Furthermore, the patient's renal and liver function should also be taken into account to avoid overdosage. Since exposure to light amplifies the risk of retinopathy in patients treated with antimalarials, dark sunglasses are recommended for patients spending much time in sunlight.

    2016-01-01

    Introduction: Incidence rates of invasive Haemophilus influenzae serotype b disease have decreased significantly since the introduction of the Hib vaccine; however, the rates in indigenous populations remain disproportionately high, specifically in the paediatric population. Additionally, with the decline of type b invasive infections, there has been a rebound in the incidence of invasive infections caused by other strains of H. influenzae, particularly serotype a. Case presentation: We present a paediatric case of septic arthritis caused by H. influenzae type a in a toddler that was fully resolved following antibiotic therapy. This report adds to other reports of septic arthritis in indigenous populations as shown through a review of recently documented H. influenzae type a septic arthritis cases. Conclusion: Socio-economic risk factors for invasive H. influenzae type a disease, such as poverty, poor housing conditions, overcrowding, smoking and substance abuse during pregnancy, as well as the need for H. influenzae type a immunization of vulnerable populations, are discussed.

    2016-01-01

    Acute osteomyelitis and septic arthritis are two infections whose frequencies are increasing in pediatric patients. Acute osteomyelitis and septic arthritis need to be carefully assessed, diagnosed, and treated to avoid devastating sequelae. Traditionally, the treatment of acute osteoarticular infection in pediatrics was based on prolonged intravenous anti-infective therapy. However, results from clinical trials have suggested that in uncomplicated cases, a short course of a few days of parenteral antibiotics followed by oral therapy is safe and effective. The aim of this review is to provide clinicians an update on recent controversies and advances regarding the management of acute osteomyelitis and septic arthritis in children. In recent years, the emergence of bacterial species resistant to commonly used antibiotics that are particularly aggressive highlights the necessity for further research to optimize treatment approaches and to develop new molecules able to fight the war against acute osteoarticular infection in pediatric patients.

    2013-10-01

    Septic arthritis of the hip in neonates is rare but can have devastating consequences. Presenting signs and symptoms may differ from those encountered in older children, which may result in diagnostic challenge or delay. Many risk factors predispose neonates to septic arthritis, including the presence of transphyseal vessels and invasive procedures. Bacterial infection of the joint occurs via hematogenous invasion, extension from an adjacent site, or direct inoculation. A strong correlation exists between younger age at presentation and severity of residual hip deformity. Diagnosis is based on clinical examination, laboratory markers, and ultrasound evaluation. Early management includes parenteral antibiotics and surgical drainage. Late-stage management options include femoral and pelvic osteotomies, trochanteric arthroplasty, arthrodesis, pelvic support procedures, and nonsurgical measures. Early diagnosis and management continues to be the most important prognostic factor for a favorable outcome in the neonate with septic arthritis.

    The incidence of uveitis associated with juvenile idiopathic arthritis (JIA) varies around the world. Our aim was to investigate the incidence and predictors of uveitis in a Nordic population-based cohort. Consecutive JIA cases from defined geographical areas in Denmark, Finland, Sweden and Norway with disease onset between January 1997 to June 2000 were followed for median 98 months in this prospective longitudinal cohort study. Potential clinical and immunological predictors of uveitis were identified with logistic regression analysis. Uveitis occurred in 89 (20.5%) of the 435 children with regular ophtalmologic follow-up among the 500 included. Chronic asymptomatic uveitis developed in 80 and acute symptomatic uveitis in 9 children. Uveitis developed at a median interval of 0.8 (range - 4.7 to 9.4) years after onset of arthritis. Predictors of uveitis were age < 7 years at JIA onset (Odds ratio (OR) 2.1, 95% confidence interval (CI) 1.3 to 3.5), presence of antihistone antibodies (AHA) > 15 U/ml (OR 4.8 (1.8 to 13.4)) and antinuclear antibodies (ANA) (OR 2.4 (1.5 to 4.0)). Mean combined IgM/IgG AHA was significantly higher in the uveitis group (19.2 U/ml) than in the non-uveitis group (10.2 U/ml) (p = 0.002). Young age at JIA onset predicted uveitis in girls (p < 0.001), but not in boys (p = 0.390). Early-onset arthritis and presence of AHA in girls, as well as presence of ANA in both genders, were significant predictors of chronic uveitis. The high incidence of uveitis in this long-term Nordic JIA cohort may have severe implications in a lifelong perspective.

    The purpose of our study was to identify the clinical and radiologic factors associated with a positive culture during image-guided hip joint aspiration. We performed a retrospective analysis of 167 consecutive hip aspirations for septic arthritis at a large tertiary medical center. Chart review was performed on the following clinical factors: serum WBC count≥11×10(3)/μL, serum erythrocyte sedimentation rate (ESR)≥20 mm/h, C-reactive protein (CRP)≥100 mg/L, synovial fluid WBC count, synovial fluid polymorphonuclear (PMN) leukocytes≥90%, fever, immunosuppression, antibiotic use, diabetes, presence of a prosthesis, and IV drug use (IVDU). Radiologic studies were reviewed for the following imaging and technical factors: presence of a sinus tract, fluid turbidity, volume of fluid (mL) aspirated, and whether the fluid analyzed was primarily aspirated or reaspirated after lavage. Logistic regression was used to calculate odds ratio (OR) and 95% CI. Of the 167 aspirations, 29 (17.4%) had positive cultures; 6 of 29 (20.7%) positive cultures occurred in reaspirated lavage fluid. On multivariate analysis using logistic regression with stepwise backward elimination, the significant clinical and radiologic predictors were elevated WBC (OR, 4.4; 95% CI, 1.1-17.3), high percentage of synovial fluid PMN leukocytes (OR, 10.6; 95% CI, 2.9-39.8), IVDU (OR, 9.0; 95% CI, 1.3-64.7), and fluid turbidity (OR, 20.5; 95% CI, 6.9-61.4). Positive hip cultures are associated with elevated serum WBC, IVDU, high percentage of synovial fluid PMN leukocytes, and fluid aspirate turbidity. Reaspiration of lavage fluid with either nonbacteriostatic saline or contrast material can yield positive cultures.

    Septic arthritis of the temporomandibular (TM) joint is rare, but it is associated with high risk for significant morbidity. We reviewed the available literature regarding the presentation, evaluation, treatment, and clinical course of TM joint septic arthritis, focusing on elements relevant to emergency physicians. In the first case, a healthy 6-year-old boy presented with fever and trismus; computed tomography with contrast revealed a TM joint effusion. After empiric intravenous antibiotics, intraoperative arthrocentesis of the TM joint returned 1 mL of flocculent fluid, which was cultured and grew pan-sensitive Streptococcus pyogenes. He was discharged home with amoxicillin/clavulanate and experienced complete resolution of his symptoms. In the second case, more than 3 weeks after extraction of her third molars, an 18-year-old woman presented with facial pain, swelling, and trismus and was found to have a loculated abscess involving the left masseteric and pterygomandibular spaces with extension to the left deep temporal region and the skull base. She experienced a complicated postoperative course and required multiple procedures and intravenous antibiotics for growth of multiple bacteria. More than a month later she underwent TM joint arthrotomy for TM joint septic arthritis, and she was found to have acute osteomyelitis. She continued to require multiple treatment modalities; 20 months after her initial presentation, she underwent left total TM joint arthroplasty for fibrous ankylosis of the TM joint. Septic arthritis of the TM joint may be caused by hematogenous spread of distant infection or local spread of deep masticator space infections. Patients may present with TM joint septic arthritis acutely or sub-acutely. Septic arthritis of the TM joint should be considered in the differential diagnosis of patients who present with trismus and pain or fever. Copyright © 2013. Published by Elsevier Inc.

    Background Adalimumab has been used in patients with moderately to severely active rheumatoid arthritis (RA) for over 10 years and has a well-established safety profile across multiple indications. Objective To update adverse events (AEs) of special interest from global adalimumab clinical trials in patients with RA. Methods This analysis includes 15 132 patients exposed to adalimumab in global RA clinical trials. AEs of interest included overall infections, laboratory abnormalities and AEs associated with influenza vaccination. Pregnancy outcome data were collected from the Adalimumab Pregnancy Registry. Results Serious infections and tuberculosis occurred at a rate of 4.7 and 0.3 events/100 patient-years, respectively. Two patients experienced hepatitis B reactivation. No significant laboratory abnormalities were reported with adalimumab-plus-methotrexate compared with placebo-plus-methotrexate. Influenza-related AEs occurred in 5% of vaccinated patients compared with 14% of patients not vaccinated during the study. Relative risk of major birth defects and spontaneous abortions in adalimumab-exposed women were similar between that of unexposed women with RA and healthy women. Conclusions This analysis confirms and expands the known safety profile of adalimumab and reports no additional safety risk of laboratory abnormalities, hepatitis B reactivation and pregnancy outcomes, including spontaneous abortions and birth defects. The benefits of influenza vaccination are reinforced.

Influenza-related AEs occurred in 5% of vaccinated patients compared with 14% of patients not vaccinated during the study. Relative risk of major birth defects and spontaneous abortions in adalimumab-exposed women were similar between that of unexposed women with RA and healthy women. This analysis confirms and expands the known safety profile of adalimumab and reports no additional safety risk of laboratory abnormalities, hepatitis B reactivation and pregnancy outcomes, including spontaneous abortions and birth defects. The benefits of influenza vaccination are reinforced.

  16. Rare coexistence of gouty and septic arthritis after arthroscopic rotator cuff repair: a case report.

    PubMed

    Coexistence of septic arthritis and gouty arthritis is rare. In particular, no reports have described the development of both gouty and septic arthritis after arthroscopic shoulder surgery. The patient was an 83-year-old man who underwent arthroscopic rotator cuff repair. He had a history of diabetes mellitus (HbA1c: 7.4%), but not of gout, and the GFR was decreased (GFR=46). During the postoperative course fever suddenly developed and joint fluid retention was found. Uric acid crystals were detected when the joint fluid was aspirated, after which when the culture results became available sepsis due to methicillin sensitive Staphylococcus aureus (MSSA) was diagnosed. On the 2(nd) day after fever onset, lavage and debridement were performed under arthroscopy, with the subsequent course uneventful with no recurrence of the infection or gouty arthritis and no joint destruction. When uric acid crystals are found in aspirated joint fluid, gouty arthritis tends to be diagnosed, but like in the present case if infection also supervenes, joint destruction and a poor general state may result if appropriate intervention is not initiated swiftly. Accordingly, even if uric acid crystals are found, the possibility of coexistence of septic arthritis and gouty arthritis should be kept in mind.

    Septic arthritis due to Streptococcus Pneumoniae appears to be relatively uncommon. Single- or clustered-case histories constitute the majority of reports on pneumococcal septic arthritis. A 70-year-old man presented with a 7-day history of pain, erythema and swelling of the left shoulder. Physical examination of the left shoulder revealed a warm, swollen, erythematous, and markedly tender to light palpation. The patient was unable to elevate his arm more than 30 degrees without pain. Arthrocentesis performed on admission produced 30 cc of grossly purulent fluid whose culture demonstrated S. Pneumoniae. The septic arthritis was treated with intravenous vancomycin and imipenem. The antibiotics were substituted when the sensitivities were known with oral ciprofloxacin and rifampycin to complete 8 weeks' total treatment. On follow-up examination 1 year later, the patient has remained afebrile and asymptomatic without evidence of increasing joint effusion or acute joint inflammation. Pneumococcal arthritis is classically described as a painful monoarticular arthritis complicating an active pneumococcal infection, generally a primary pulmonary infection. Pneumococcal arthritis appears to be predominantly a disease affecting the elderly. Clinical presentation ranges from septicemia to indolent infection with few systemic symptoms. With adequate antibiotic therapy and aspiration or drainage of the joint, the prognosis for return of normal joint function appears to be excellent. Although pneumococcal organisms are not likely causes, this bacteria should certainly be considered as a possible cause of arthritis or prosthetic infection.

    A case of rarely encountered nontyphoidal Salmonella septic arthritis of the elbow in an infant with no preexisting disease is reported. Salmonella etiology was not suspected in this case, and the diagnosis was made only after bacterial isolation. Aspiration of the infected joint with radiological guidance initially failed to give a good clinical response. Arthrotomy was done with intravenous cefotaxime for 4 weeks followed by 2 weeks oral ciprofloxacin therapy to which the child responded favorably. Up to our knowledge this is the first case of nontyphoidal salmonella elbow septic arthritis in an infant in Saudi Arabia to be reported in the English literature.

    Septic arthritis caused by Streptococcus pneumoniae is uncommon. Most of the patients who have invasive pneumococcal infection have underlying diseases associated with impaired immune function. We report a case of polyarticular pneumococcal septic arthritis in a previously healthy adult as the first manifestation of selective immunoglobulin (Ig)M deficiency. The patient had no evidence of autoimmune disease or malignancy. Serum IgG, IgA, and complement levels were normal. Numbers of lymphocyte subsets were in normal range except that of CD4+ cells, which was slightly low. Invasive pneumococcal disease in a healthy adult should lead to further investigation for underlying diseases including primary immunodeficiencies.

    Septic arthritis is encountered very rarely during the neonatal period and its diagnosis can delay because of atypical symptoms, thus it may lead to serious sequelae. The sequale can be prevented by early diagnosis and concomitant treatment. In neonates, pain can be experienced as a result of pseudoparalysis and of movement of the effected joints. A 17-day-old neonatal patient was brought to our hospital with complaint of unrest and then diagnosed with septic arthritis due to propagation of Klebsiella pneumoniae in joint fluid culture was represented because of the rarity of such a case.

In 9 patients with 10 episodes of septic arthritis concentrations of synovial fluid lactic acid were significantly higher (mean 10.8 mmol/l) than in 33 patients with nonseptic effusions (mean 3.1 mmol/l). With this method concentrations of synovial fluid lactic acid provide a rapid diagnostic guide in the separation of septic from nonseptic arthritis. PMID:7305472

    2007-01-01

    Background Streptobacillus moniliformis is a zoonotic agent associated with rodent contacts. Although it is more commonly reported to cause rat-bite fever with reactive arthritides, it can also lead to pyogenic infection of the joints. Case presentation We present a lady with past history of osteoarthritis developing streptobacillary septic arthritides of the right knee and left wrist, and required antibiotic and arthrotomy for treatment. We also review 11 previously reported cases of streptobacillary septic arthritis to discuss the characteristics, treatment, prognosis of the infection, and illustrates the differences between streptobacillary rat-bite fever and septic arthritis. Among this patient population, most patients had potential contact with rats (91.6%). The knee is the most commonly affected joint (58.3%), and 83.3% patients having polyarticular involvement. As opposed to rat-bite fever, fever and rash was only present in 58.3% and 16.7% of patients respectively. S. moniliformis bacteremia is uncommon (8.4%) and the prognosis is good. Conclusion Arthrocentesis is useful in distinguishing streptobacillary septic arthritis from reactive arthritis of rat-bite fever. The sole use of commercial media containing sodium polyanethol sulfonate may render the bacterial culture negative. A detailed history of possible exposure to rodents should be elicited from patients with arthritis in order to facilitate microbiologic diagnosis. PMID:17561996

    Rheumatoid arthritis (RA)--a widespread chronic inflammatory disease in industrialized countries--is characterized by a persistent and progressive joint destruction. The chronic pro-inflammatory state results from a mutual activation of the innate and the adaptive immune system, while the exact pathogenesis mechanism is still under discussion. New data suggest a role of the innate immune system and especially polymorphonuclear granulocytes (PMNs, neutrophils) not only during onset and the destructive phase of RA but also at the chronification of the disease. Thereby the enzymatic activity of myeloperoxidase (MPO), a peroxidase strongly abundant in neutrophils, may be important: While its peroxidase activity is known to contribute to cartilage destruction at later stages of RA the almost MPO-specific oxidant hypochlorous acid (HOCl) is also discussed for certain anti-inflammatory effects. In this study we used pristane-induced arthritis (PIA) in Dark Agouti rats as a model for the chronic course of RA in man. We were able to shown that a specific detection of the HOCl-producing MPO activity provides a sensitive new marker to evaluate the actual systemic inflammatory status which is only partially detectable by the evaluation of clinical symptoms (joint swelling and redness measurements). Moreover, we evaluated the long-term pharmacological effect of the well-known anti-inflammatory flavonoid epigallocatechin gallate (EGCG). Thereby only upon early and continuous oral application of this polyphenol the arthritic symptoms were considerably diminished both in the acute and in the chronic phase of the disease. The obtained results were comparable to the treatment control (application of methotrexate, MTX). As revealed by stopped-flow kinetic measurements, EGCG may regenerate the HOCl-production of MPO which is known to be impaired at chronic inflammatory diseases like RA. It can be speculated that this MPO activity-promoting effect of EGCG may contribute to the

  5. Rutin has therapeutic effect on septic arthritis caused by Candida albicans.

    As of late, numerous reports have demonstrated the multiple biological activities of polyphenolic flavonoids. Amongst these reports, some indicate that the flavonoids play an important role in inflammation therapy. In this present study, we investigated the effect of rutin, a polyphenolic flavonoid, on septic arthritis due to Candida albicans, a major etiological agent that causes fungal arthritis. To induce septic arthritis, an emulsified mixture of C. albicans cell wall and Complete Freund's Adjuvant (CACW/CFA) was injected into BALB/c mice via hind footpad route once a day, everyday, for three days. In order to determine the effect of rutin, twenty-four hours after the final injection, mice having the swollen footpad were given the flavonoid (1 mg/dose/mouse) intraperitoneally every other day for three times. The footpad-edema was measured for a period of 17 days. Results showed that the rutin treatment reduced app. 45% of the edema at the peak day (day 11) of septic arthritis (P<0.05). In addition, 6 days after the peak, there was an app. 35% additional reduction of the edema (P<0.05). We found that this anti-arthritic activity was mediated by rutin's ability to inhibit nitric oxide production from macrophages and T-cells proliferation. Furthermore, this flavonoid also inhibited the growth of C. albicans yeast cells (P<0.01) and resulted in no hemolysis. These data indicate that rutin, which has both anti-arthritic and antifungal effects, can safely be administered into the blood circulation for treatment of septic arthritis caused by C. albicans. Ultimately, it can be suggested that the dual effects of rutin, anti-arthritic and anti-candidal may be helpful as an all-in-one treatment for septic arthritis.

    Objective. A long-term follow-up of patients with rheumatoid arthritis (RA) to evaluate factors related to coronary artery calcification (CAC). Methods. All 22 eligible patients (4 males/18 females, mean age 65 years, and RA-duration 30–36 years) from the original (baseline; n = 39) study of atherosclerosis were included. Inflammation, cardiovascular risk factors, and biomarkers were measured at baseline. At follow-up 13 years later, CAC was assessed by computed tomography (CT) and the grade of inflammation was measured. Multivariate analysis of differences between patients with low (0–10) and high CAC (>10) was done by orthogonal projection to latent structures (OPLS). Results. Ten patients had CAC 0–10 and 12 had >10 (range 18–1700). Patients with high CAC had significantly higher ESR (24.3 versus 9.9 mm/h) and swollen joint count (2 versus 0). The OPLS models discriminated between patients having high or low CAC. With only baseline variables, the sensitivity was 73% and the specificity 82%. The model that also included inflammatory variables from follow-up had a sensitivity of 89% and a specificity of 85%. Exclusion of baseline intima media thickness and plaque from the latter model modestly reduced the accuracy (sensitivity 80% and specificity 83%). Conclusions. CAC is related to inflammation in patients with RA. PMID:27648442

    The aim of this article was to assess the efficacy and safety of apremilast in treatment of psoriatic arthritis (PsA) with meta-analysis method. We included four randomized clinical trials identified from MEDLINE, EMBASE, Cochrane Library, "ISRCTN Register" and "ClinicalTrials.gov" which compared apremilast with placebo. The meta-analysis was performed by the software of Review Manager, version 5.2. Apremilast was associated with significantly higher proportion of patients who achieved ACR20 at week 16 (in apremilast 20 mg subgroup, odds ratio [OR]= 2.04, 95% confidence interval [Cl] 1.58-2.63, P<0.00001; in apremilast 30 mg subgroup, OR=2.53, 95%Cl 1.96-3.25, P<0.00001) and significantly higher scores of Health Assessment Questionnaire-Disability Index (in apremilast 20 mg subgroup, WMD=-0.11, 95%Cl -0.16~-0.06, P<0.0001; in apremilast 30 mg subgroup, WMD=-0.16, 95%Cl -0.21~-0.11, P<0.00001). Apremilast was as safe as placebo in terms of serious adverse events (AEs). The AEs occurred in participants with apremilast were mild and well tolerated during treatment. Apremilast can be used in treatment of PsA with lower costs, oral availability and well tolerated. But the long-term benefit and safety of apremilast should be further investigated.

    We carried out a survival analysis of elbow synovectomy (ES) and excision of the radial head (RHE) performed on 171 rheumatoid elbows. The failure criteria were revision surgery (performed or desired) and/or the presence of significant or severe pain. The cumulative survival was 81% at one year which thereafter decreased by an average of 2.6% per year. The strongest predictor for success was a low preoperative range of supination-pronation when corresponding survival curves were compared. A low range of flexion-extension also predicted failure. Combining both factors gave better prediction (failure: 6.3% v 67%), but a long duration of elbow symptoms before surgery predicted failure (72%, p = 0.04). At review, there was a mean gain of 50 degrees in supination-pronation and 11 degrees in flexion-extension; both correlated with success. Failure correlated with recurrence of synovitis, elbow instability, ulnar neuropathy, poor general mobility and poor upper-limb function. The last was independently affected by the severity of RA in the ipsilateral shoulder. Our findings show that although the short-term result of ES and RHE in rheumatoid arthritis is good, the long-term outcome is poor except in a subgroup with more than 50% limitation of forearm rotation.

    Septic arthritis is a severe and rapidly debilitating disease associated with severe joint pain, inflammation and oxidative stress. Nitroxyl (HNO) has become a nitrogen oxide of significant interest due to its pharmacological endpoints that are potentially favorable for treating varied diseases. However, whether HNO also serves as a treatment to septic arthritis is currently unknown. The aim of this study was to investigate the effect of the HNO donor, Angeli's salt (AS), in the outcome of chronic Staphylococcus aureus (S. aureus)-induced septic arthritis in mice. Daily treatment with AS inhibited mechanical hyperalgesia and inflammation (edema, leukocyte migration, cytokines release and NF-κB activation, and oxidative stress) resulting in reduced disease severity (clinical course, histopathological changes, proteoglycan levels in the joints, and osteoclastogenesis). In addition, AS decreased the number of S. aureus colony forming unities in synovial tissue, enhanced the bactericidal effect of macrophages and inhibited the worsening of systemic inflammatory response (leukocyte counts in the lung and systemic proinflammatory cytokine concentration). Our results suggest for the first time the therapeutic potential of AS in a model of septic arthritis by mechanisms involving microbicidal effects, anti-inflammatory actions and reduction of disease severity.

    Understanding the nature and function of fungal exoantigens might lead to novel approaches in the treatment and prophylaxis of some infectious diseases. Septic arthritis represents a serious problem for medicine due to the high incidence rate and severe complications. The present study aimed at assessing the immunomodulatory effects of Trichophyton rubrum culture filtrate as a novel compound in experimental septic arthritis. The septic arthritis was haematogenously induced in Sprague-Dawley rats by a single intravenous injection of 10(9) colony forming units of the human clinical isolate Staphylococcus aureus producing toxic shock syndrome toxin-1. Trichophyton rubrum culture filtrate at two different doses 20 and 40 mg/kg was administered intraperituneally two days after bacterial inoculation in the treatment groups and concurrently with the appearance of clinical signs in the patient groups. The administration of Trichophyton rubrum solution was continued every other day for 10 injections. The clinical evaluation showed that Trichophyton rubrum-treated rats were significantly protected from disease development compared with untreated controls. This finding was correlated with results of radiological evaluation of the involved joints. Although, the inflammatory cell infiltration, cartilage/bone destruction and synovial hypertrophy had been decreased in the treatment groups in comparison with arthritic controls however, the histological changes were not significant in these two groups. It is possible that Trichophyton rubrum antigens may play a role in modulating the immune responses and would be efficient in septic arthritis treatment.

    2016-01-01

    Introduction: Mucormycosis is a rare fungal infection, but can cause substantial morbidity and mortality in both immunocompromised and immunocompetent patients. Apophysomyces is a mucormycetes species ubiquitous in nature, particularly in soil, decaying wood and other organic matter. Apophysomyces is known to cause cutaneous fungal infections, particularly after penetrating trauma. Septic arthritis is a rare clinical manifestation. Case presentation: We describe a case of Apophysomyces trapeziformis causing septic arthritis of the knee of a patient with multiple myeloma. He was treated multiple times for bacterial septic arthritis with minimal improvement. Surgical tissue specimens finally grew mucoraceous mould, and DNA sequencing and morphological assessment of spores identified the mould as A. trapeziformis. The patient was treated with amphotericin B and posaconazole, but ultimately required an above-the-knee amputation for definitive treatment. Conclusion: This case illustrates the need to evaluate for fungal infection in a persistent septic arthritis that is culture negative and refractory to empiric antibiotics, particularly in an immunocompromised individual. It also shows the importance of a thorough social history and adequate tissue specimens for culture. PMID:28348796

    A combination of surgical and medical treatment is normally required for patients with septic arthritis. Antibiotics selected for use on these patients are normally based on tissue culture results. However, in sub-acute and chronic septic arthritis cases, the results of the culture are usually negative as a result of prior treatment. The present study will investigate the incidence of culture-negative septic arthritis and the outcomes based on the use of first-line drug antibiotics for the treatment of sub-acute and chronic septic arthritis. For the present study, the authors retrospectively reviewed medical records of surgically treated septic arthritis cases over the past 10 years at Siriraj Hospital. The patient culture results, the antibiotics used, and the results of treatment were all recorded and analyzed. One hundredfifty-three septic arthritis patients were reviewed. Sixty-two patients were classified as having been diagnosed with either sub-acute or chronic septic arthritis. Thirty-six of 62 patients (58.1%) had a negative culture result. In the culture-positive patients, 42.3% had Streptococcus, 26.9% had Staphylococcus aureus, 11.5% had other gram positive bacteria, 15.4% had gram-negative bacteria, and 3.8% had tuberculus infection. In the culture-negative sub-acute and chronic group (36 of 62), 23 patients received Cefazolin, nine patients received Cloxacillin, and four patients received Clindamycin. Successful results were 69.9%, 66.7% and 75%, respectively. The present study reflects that the incidence ofculture-negative, sub-acute and chronic septic arthritis is approximately 58.1%. The first-line class of antibiotics remains the appropriate antibiotic choice for these patients because they are still effective for treatment of septic arthritis in up to 70% of all cases.

    To investigate the serum and synovial fluid serum amyloid A (SAA) response in equine models of synovitis and septic arthritis and to compare handheld and validated immunoturbidometric assays for SAA quantification. Controlled, experimental study. Healthy adult horses (n = 9). Synovitis (n = 4) and septic arthritis (n = 5) were induced using lipopolysaccharide and Staphylococcus aureus, respectively, and serial serum and synovial fluid samples were collected. Serial synovial fluid cytology was performed for both models and synovial fluid from the septic arthritis model was submitted for bacterial culture. Serum and synovial fluid SAA were quantified by handheld test and immunoturbidometric assay. Cytologic and SAA data were compared within and between models (mixed model ANOVA) and results of SAA assays were compared using category-by-category analysis (weighted kappa coefficient). Synovial fluid total nucleated cell counts and total protein increased significantly following induction of both models. Serum and synovial fluid SAA remained normal in synovitis horses and increased significantly in septic arthritis horses. Serum SAA increased more rapidly than synovial fluid SAA. Agreement was 98% when SAA concentrations were low (<50 μg/mL) but the assays diverged when concentrations were greater than ∼100 μg/mL. Overall, there was good category-by-category agreement between SAA assays (weighted kappa = 0.824). Serum and synovial fluid SAA may be useful adjuncts in diagnosing septic arthritis in horses. SAA concentrations for the assays diverged and examination using a larger sample size is needed before direct numeric comparisons between the assays can be made. © Copyright 2016 by The American College of Veterinary Surgeons.

    With the ameliorating prognosis of rheumatoid arthritis (RA), the role of comorbidities as causes of work disability (WD) may increase. The aim of this study was to determine the contribution of psychiatric and cardiovascular (CV) comorbidities as the leading causes of long-term WD among patients with recent-onset RA. Between 2000 and 2007, all incident, working-age and non-retired RA patients were identified from a Finnish nationwide register. From other registers, we identified the RA patients who were granted a permanent or temporary disability pension by 31 December 2008. The incidences of disability pensions with CV diseases (ICD-10 codes I00-I99) or psychiatric disorders (F20-F69) as the leading causes were assessed and compared with the general population. We identified a cohort of 7831 patients with RA. During follow-up, 1095 patients were granted a disability pension. After adjusting for competing risks, the 9-year cumulative incidence of WD caused by RA, a psychiatric comorbidity, or a CV disease was 11.9, 1.3, and 0.5%, respectively. Compared to the general population, the age- and sex-specific standardized incidence ratio (SIR) of WD due to psychiatric comorbidities was 0.99 [95% confidence interval (CI) 0.80-1.23] and due to CV disease 1.75 (95% CI 1.23-2.51). In the study cohort with recent-onset RA, the 9-year cumulative incidence of disability pensions caused by psychiatric or CV comorbidities was only 11% or 4%, respectively, of that caused by RA itself. Compared to the general population, the risk of WD due to CV disease was increased.

    Background Septic arthritis is a serious joint disease often caused by Staphylococcus aureus (S. aureus). Receptor for Advanced Glycation End products (RAGE) has an important role in several infections. We sought to investigate the role of RAGE in staphylococcal septic arthritis and sepsis in mice. Methods Wild-type (WT) and RAGE deficient (RAGE-/-) mice were intra-articularly or intravenously inoculated with an arthritic or septic dose of S. aureus LS-1 strain. Clinical arthritis, weight development and mortality were monitored for 14 days. Serum levels of cytokines, kidney bacterial loads as well as micro-CT and histopathology of the joints were assessed. Results RAGE-/- mice with septic arthritis had significantly lower IL-17A and higher bone mineral density (BMD) compared to the control group. However, no significant differences between the groups were observed regarding the weight loss, the severity and frequency of arthritis, and bacterial loads in the kidneys. In mice with sepsis, the overall mortality rate was similar in RAGE-/- (39%) and in WT mice (45%). However, RAGE-/- mice with sepsis had significantly higher bacterial load in their kidneys compared to the WT controls. In line with data from hematogenous S. aureus arthritis, RAGE deficiency had no impact on arthritis severity in local joint infection. Conclusions Our results indicate that lack of RAGE has no significant impact on septic arthritis. However, RAGE-/- mice had significantly higher BMD compared to WT mice, which coincided with lower IL-17A in RAGE-/- mice. In sepsis, RAGE deficiency impairs bacterial kidney clearance.

    Septic arthritis of the temporomandibular joint (TMJ) is a very rare complication of otitis externa that can lead to ankylosis and destruction of the joint. We report the case of a 74-year-old man who developed aspergillosis of the TMJ following otitis externa. To the best of our knowledge, this is the first reported case of TMJ septic arthritis secondary to otitis externa caused by Aspergillus flavus. The patient was successfully managed with condylectomy, debridement, and drug treatment with voriconazole.

    The complement system plays an essential role in the innate immune response and protection against bacterial infections. However, detailed knowledge regarding the role of complement in Staphylococcus aureus septic arthritis is still largely missing. In this study, we elucidated the roles of selected complement proteins in S. aureus septic arthritis. Mice lacking the complement component 3 (C3(-/-)), complement factor B (fB(-/-)), and receptor for C3-derived anaphylatoxin C3a (C3aR(-/-)) and wild-type (WT) control mice were intravenously or intra-articularly inoculated with S. aureus strain Newman. The clinical course of septic arthritis, as well as histopathological and radiological changes in joints, was assessed. After intravenous inoculation, arthritis severity and frequency were significantly higher in C3(-/-)mice than in WT controls, whereas fB(-/-)mice displayed intermediate arthritis severity and frequency. This was in accordance with both histopathological and radiological findings. C3, but not fB, deficiency was associated with greater weight loss, more frequent kidney abscesses, and higher bacterial burden in kidneys. S. aureus opsonized with C3(-/-)sera displayed decreased uptake by mouse peritoneal macrophages compared with bacteria opsonized with WT or fB(-/-)sera. C3aR deficiency had no effect on the course of hematogenous S. aureus septic arthritis. We conclude that C3 deficiency increases susceptibility to hematogenous S. aureus septic arthritis and impairs host bacterial clearance, conceivably due to diminished opsonization and phagocytosis of S. aureus.

    We present a 51-year-old male patient with Brucella abortus septic arthritis in the right knee following arthroscopic meniscus surgery. He had eaten a traditional dish of raw minced cattle conceptus (bovine fetus) that was prepared after the cow was slaughtered. Despite treatment with empirical antibiotics and debridement of the postoperative surgical wound, the infection persisted without improvement. Polymerase chain reaction sequencing identified Brucella abortus from tissue samples obtained from the patient. After confirmation of the diagnosis of brucellar infection, antibiotics were replaced with doxycycline and rifampin, which were used for 4 months. In patients with a non-specific arthralgia who eat raw meat or live close to animals, it is important to consider the possibility of septic arthritis due to infection with Brucella spp.

    Septic arthritis is not a frequent, but quite classical pathology in children. It can be followed by a severe outcome in case of delayed and/or inadequate treatment. The drainage of the infected joint associated with a prompt and adapted antibiotherapy are together the cornerstones of this treatment. The isolation and identification of the causative microorganism is also of the highest importance. Up to now, unfortunately, a large proportion of septic arthritis are treated by antibiotics although all culture remain negative. This paper has two objectives: one is to present the different steps to optimize the assessment and diagnosis; the second, to increase the sensitivity of the pathogen identification. At last, we present our proposal for empirical antibiotherapy.

    Two children, a girl aged 2 years and a boy aged 10 months, were moderately ill with signs of inflammation of the left and the right knee, respectively. Both had had pharyngitis, and the boy also had paronychia of the right foot. The Gram preparation of synovial fluid showed Gram-positive cocci in the girl, while Kingella kingae was cultured. In the boy, a Moraxella was cultured from the synovial fluid using an aerobic blood culture system. Both recovered without sequelae after adequate antibiotic treatment. The micro-organisms cultured were Gram-negative bacteria, which are rarely seen in septic arthritis and are difficult to demonstrate. In young children, septic arthritis often presents with mild symptoms and inconclusive laboratory findings. Even if the Gram preparation of the synovial fluid shows no micro-organisms, unusual pathogens may be isolated by means of an aerobic blood culture system.

    A 32-month-old boy presented with febrile limping that had developed over 6days, associated with right lumbosacral inflammatory swelling. Magnetic resonance imaging (MRI) showed joint effusion of the right L5-S1 zygapophyseal joint, complicated by destructive osteomyelitis of the L5 articular process and paraspinal abscess. Surgery was decided to evacuate the fluid accumulation and rule out differential diagnoses. The diagnosis of septic arthritis of the facet joint was confirmed intraoperatively; real-time quantitative PCR analysis identified Kingella kingae. This is the first substantiated paediatric case of zygapophyseal joint septic arthritis due to K. kingae. K. kingae is the most common pathogen responsible for invasive osteoarticular infection in children under 4years of age. Since empiric antibiotics are effective in early stages, physicians should consider the possibility of spinal infections due to K. kingae when a limping child under 4years of age presents with a fever.

    Rupture of cruciate ligaments of the knee is a common injury that is repaired by arthroscopic reconstruction, which can give rise to septic arthritis. The objective of this article is to describe the clinical and microbiological aspects of this entity. Retrospective review of cases of septic arthritis following arthroscopic reconstruction of cruciate ligaments of the knee that occurred at a single institution from 2000-2015. According to time elapsed from surgery, infections were classified as acute (< 14 days), subacute (> 14 days and<30 days), and late (> 30 days). A descriptive and comparative analysis stratified by type of infection and causative microorganism was performed. 3,219 patients underwent arthroscopic reconstruction of cruciate ligaments of the knee and 30 (0.9%) developed septic arthritis. Seventeen (57%) were acute infections and 12 (40%) subacute; there was one late infection. The causative microorganisms were coagulase-negative Staphylococci (n=13; 43%), Staphylococcus aureus (n=12; 40%), other grampositive cocci (n=3; 10%), and gramnegative bacilli (n=2; 7%). All patients underwent arthroscopic debridement; no grafts were removed. All patients received antibiotic therapy for a median of 23.5 days (range: 14 - 78 days); all infections were cured. No significant differences were found in any of the variables analysed among the infection type or the causative microorganism. Septic arthritis after arthroscopic reconstruction of cruciate ligaments of the knee is uncommon. It generally presents within 4 weeks of surgery and is caused by Staphylococci. Its treatment consists of arthroscopic debridement (without necessarily removing the graft) and antibiotic therapy.

    Objectives Procalcitonin (PCT) is an accurate marker for differentiating bacterial infection from non-infective causes of inflammation or viral infection. However, there is only one study in children which tested procalcitonin as a diagnostic aid in skeletal infections. With this study we sought to evaluate the sensitivity, specificity and predictive values of procalcitonin for identifying bone and joint infection in children evaluated in the emergency department for non traumatic decreased active motion of a skeletal segment. Methods Patients aged 1 month to 14 years were prospectively included in the emergency department when suspected for osteomyelitis or septic arthritis. Procalcitonin levels, C reactiv protein, white blood cell count were measured and bacteriological samples were collected before initiation of antibiotic treatment. Patients were assigned to 3 groups according to the degree of suspected infection: group 1 confirmed infection, group 2 presumed infection and group 3 non infected patients. Results Three hundred thirty nine patients were included (118 girls and 221 boys). Group 1 comprised 8 patients (2 had PCT levels > 0.5 ng/ml). Two had osteomyelitis and 6 septic arthritis. Forty children were incuded in group 2 (4 had PCT levels > 0.5 ng/ml). Eighteen had presumed osteomyelitis and 22 presumed septic arthritis. Group 3 comprised 291 children (9 PCT levels > 0.5 ng/ml) who recovered without antibiotic treatment. The specificity of the PCT as a marker of bacterial infection (comparing Group 1 and Group 3) was 96.9% [95% CI, 94.2-98.6], the sensitivity 25% [95% CI, 3.2-65.1], the positive predictive value (PPV) 18.2% [95% CI, 2.3-51.8] and the negative predictive value (NPV) 97.9% [95% CI, 95.5-99.2]. Conclusion PCT is not a good screening test for identifying skeletal infection in children. Larger studies are needed to evaluate still more the place of PCT measurements in the diagnosis of osteomyelitis and septic arthritis. PMID:19889215

    We present a case of chronic posterior hip dislocation after severe joint destruction following septic arthritis. In the absence of trauma, infection must be considered in the differential diagnosis of a dislocated joint particularly in patients with risk factors such as intravenous drug abuse and immune compromise. Excision arthroplasty of the hip was performed with good pain relief and functional outcomes. This is an excellent temporary or permanent solution in managing such complex cases although alternative management options are discussed.

    Pseudogout is a crystal-induced arthropathy characterized by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in synovial fluid, menisci, or articular cartilage. Although not very common, this entity can be seen in patients with chronic kidney disease (CKD). Septic arthritis due to Mycobacterium avium-intracellulare (MAI) is a rare entity that can affect immunocompromised patients such as those with acquired immunodeficiency syndrome (AIDS) or those who are on immunosuppressive drugs. Here, we describe a 51-year-old female who presented with fever, right knee pain, swelling, warmth, and decreased range of motion for several days. The initial assessment was consistent with pseudogout, with negative bacterial and fungal cultures. However, due to high white blood cell (WBC) count in the synovial fluid analysis, she was empirically started on intravenous (IV) vancomycin and piperacillin-tazobactam and discharged on IV vancomycin and cefepime, while acid-fast bacilli (AFB) culture was still in process. Seventeen days later, AFB culture grew Mycobacterium avium-intracellulare (MAI), and she was readmitted for relevant management. This case illustrates that septic arthritis due to MAI should be considered in the differential diagnosis of septic arthritis in immunocompromised patients. PMID:27803833

    Purpose. Primary septic arthritis is a rare differential diagnosis of acute hip pain in adults. Inspired by the success of all-arthroscopic treatment in pediatric patients, we developed a diagnostic and surgical pathway for our adult patients. Methods. Seven patients, average age 44 ± 13.7 years with acute hip pain since 4.4 ± 2.9 days in the average, were included. Septic arthritis was confirmed by joint aspiration and dissemination was excluded by MRI and standard radiographs. Surgical treatment consisted of immediate arthroscopic lavage using 4 portals for debridement, high-volume irrigation, partial synovectomy, and drainage. Results. Patients were treated in hospital for 12.4 ± 3.1 days (range 7–16 days). WBC and CRP returned to physiological levels. During the mean follow-up of 26.4 ± 19.4 months (range 13–66 months) no patient showed recurrence of infection. The 5 patients with an unimpaired hip joint prior to the infection had a mean modified Harris Hip Score of 94 ± 5.6 points (range 91–100) at final follow-up. Conclusions. Arthroscopic therapy using a minimally invasive approach with low perioperative morbidity for the treatment of primary septic arthritis of the adult hip is able to restore normal hip function in acute cases without dissemination of the infection.

    Septic arthritis of the knee is a potentially life-threatening condition and can be associated with many late complications. The key of success of management of septic arthritis of the knee joint is early aggressive treatment of surgical debridement and decompression and antibiotic therapy. In adults, arthroscopic drainage with synovectomy is the treatment of choice in septic arthritis of the knee, with lower rates of infectious recurrence than needle aspiration and better functional results than open surgery. Repeated arthroscopic debridement and drainage is needed in case of delayed treatment with an advanced arthroscopic stage of the infection, early unfavorable course, or multiresistant germ. In these situations, synovectomy should be as complete as possible to maximize the reduction of the bacterial burden and avoid the need of further debridement. The purpose of this Technical Note is to describe the details of complete arthroscopic synovectomy of the knee joint. This includes 2 circles of circumferential synovectomy. One circle is in the axial plane and includes the intercondylar notch, anterior, posterior, medial, and lateral compartments. The other circle is in the coronal plane and includes the supra-patellar pouch, medial and lateral recesses, and the anterior compartment.

    To describe bacteriologic epidemiology of bone and joint infections, a total of 52 osteomyelitis, 52 arthritis and 20 osteoarthritis of children aged one month to 15 years during a one-year period (2001) were included in a retrospective unicentric review. The mean age was 3,9 +/-3,6 years. Fever and pain were the most common clinical symptoms. The site of infection was single in 95%, involving lower extremities in 80%. Bone scintigraphy was abnormal in 71% of osteomyelitis. Positive cultures was obtained in 29% of all cases (blood cultures: 20%, aspiration cultures: 29%), but in 42% of cases which have both blood and aspiration cultures. Thirty-six bacteria were identified: 19 Staphylococcus (14 aureus), ten Streptococcus (four pneumoniae), three Salmonella, three Kingella kingae, one Moraxella. All the isolates were susceptible to the empiric antibiotic therapy. Outcome was good in 100% of osteomyelitis and in 96% of arthritis.

    Group C streptococci are flora members of skin, nasopharynx, gastrointestinal and genitourinary systems. They are rare causes of human pharyngitis, arthritis, pneumonia, meningitis and bacteremia. In this report, a 71-years old male patient with Streptococcus equisimilis arthritis/prosthetic joint infection has been presented. The patient was admitted to the emergency service with the complaints of erythema, swelling and tenderness on right knee which had total knee prosthesis. Examination of synovial fluid punction sample yielded abundant amount of leukocytes (> 1000 cells/mm3). Empirical ampicillin-sulbactam (1 g q6h, parenterally) therapy was initiated. Bacteria which have been cultivated from synovial fluid specimen were identified as S. equisimilis. The isolate was found to be susceptible to penicilin, erythromycin and teicoplanin, and resistant to chloramphenicol and tetracycline. Although clinical presentation improved during the first ten days, symptoms recurred after the 10th day and the therapy was switched to teicoplanin. The recurrence was thought to be the result of antibiotic tolerence. The patient was treated successfully with teicoplanin, and no relapse or reinfection was observed during one year of follow-up. To our knowledge this is the first case of S. equisimilis arthritis reported from Turkey and first case of S. equisimilis associated prosthetic joint infection.

    Septic arthritis due to methylcyllin resistant Staphylococcus aureus (MRSA) is a serious infection that has increased in incidence in the past 10years. We conducted a retrospective study (1984-2011) in which a description of the clinical and epidemiological characteristics of MRSA arthritis in adults was performed and then compared to native joint infections caused by MRSA vs. methylcyllin sensitive Staphylococcus aureus (MSSA). Fourteen MRSA infections were included (7 native joint, 5 prosthetic and 2 bursae). No case was polyarticular. There was significant comorbidity, although none was associated to rheumatoid arthritis. Seven patients had bacteremia. Four required surgical treatment. Six died. When comparing the 7 patients with native joint MRSA infection with the 17 cases caused by MSSA, no significant differences in risk factors were seen, except more malignancies in the MRSA group. The infection was polyarticular in 7 cases (41%) of the MSSA group. Bacteremia was more frequent in the MRSA group (71.4 vs 58.8%). Empirical antibiotic was useful in 28.6% of MRSA cases versus 100% of MSSA cases. There was a greater tendency to associated mortality in MRSA arthritis (57.1% vs 17.6%, P=.07). MRSA septic arthritis is a serious condition that occurs in the elderly and patients with high comorbidity. It is usually monoarticular, with positive blood cultures and higher mortality than MSSA arthritis. In patients at risk, vancomycin empiric antibiotic therapy is indicated.

    The sensitivity of Gram staining is known to be suboptimal for the diagnosis of native joint septic arthritis. We lack information about the accuracy of Gram compared to other microscopic staining techniques for predicting infection in different patient populations. This was a cohort study with cost evaluations at the Orthopaedic Service of Geneva University Hospitals (January 1996-October 2012). Among 500 episodes of arthritis (196 with immunosuppression, 227 with underlying arthroplasties and 69 with gout or other crystals in synovial fluid), Gram staining revealed pathogens in 146 episodes (146/500, 29 %) or in 146 of the 400 culture-positive episodes (37 %). Correlation between the Gram and acridine staining of the same sample was good (Spearman 0.85). Overall, the sensitivity, specificity, positive predictive value and negative predictive value of Gram stain for rapid diagnosis of septic arthritis was 0.37, 0.99, 0.99 and 0.28, respectively, compared to microbiological cultures. Quite similar values were recorded across the different patient subpopulations, in particular for sensitivity values that were 0.33 for patients with prosthetic joint infections, 0.40 for immunosuppressed patients, 0.36 for patients under antibiotic administration and 0.52 for patients with concomitant crystalline disease. The sensitivity of Gram or acridine orange staining for a rapid diagnosis of episodes of septic arthritis is suboptimal compared to microbiological culture, regardless of underlying conditions, immunosuppression or antibiotic therapy. The sensitivity in the presence of synovial fluid crystals is moderate. Acridine orange and Gram stains are equivalent.

    Septic arthritis is an important concern for rheumatologists in the evaluation of joint disease. Very few studies have addressed the microbiologic epidemiology and outcomes of septic arthritis in the USA since the year 2000. We performed a retrospective study of septic arthritis in a tertiary hospital in West Texas from the year 2000 to 2013. We recorded data on patient demographics, microbiologic etiology, treatment patterns, and outcomes. The most common causative organisms were Staphylococcus aureus and Streptococcus spp. Methicillin-resistant Staphylococcus aureus (MRSA) caused septic arthritis in 22.6 % of the cases. MRSA septic arthritis was associated with low rates of adequate empiric antimicrobial therapy. The mortality due to sepsis in our study was 5.5 %. Patients with septic arthritis had a mean length of stay of 13.5 ± 12.1 days and required 2.1 ± 1.4 joint operations. Many patients (29.2 %) had readmissions due to complications, and these patients had high rates of home health utilization and transfers to other facilities post hospital discharge. In our logistic regression analysis model, factors associated with poor outcomes in septic arthritis were MRSA, older age, and prosthetic joint infection. Septic arthritis is associated with significant mortality, morbidity, and health care costs, and more studies are needed to improve outcomes, especially considering the increasing rates of MRSA as the pathogen.

    This article presents a case of primary septic arthritis of the knee due to serogroup C Neisseria meningitidis. A 19-year-old female presented to the emergency department with a painless but swollen knee joint which had started 2 days previously and fever (38 °C). The patient reported that she suddenly felt unwell 3 days ago and developed a rush at the same time which had almost disappeared when arrived at the emergency department. The patient was admitted to hospital and an antibiotic therapy was started with sulbactam and ampicillin. Initially, incubation of synovial fluid over the next 3 days did not result in detection of any pathogens; therefore, a reactive arthritis was assumed until Neisseria meningitidis was detected in cultures of the synovial fluid. Therapy was then switched to antibiotic therapy with ceftriaxon and arthroscopic irrigation was performed. The patient quickly recovered and was discharged from hospital after 14 days. This case example shows the difficulties of the clinical and microbiological diagnostics of a primary septic meningococcal arthritis; however, the treatment is relatively easy and mostly successful compared to other forms of bacterial joint infection.

    A 52-year-old woman with Crohn’s disease presented with septic arthrtis of the knee. This condition coincided with a symptomatic flare of her Crohn’s disease due to an ileal inflammatory stenosis, manifested as a phlegmonous mass palpable in the right lower quadrant and a small bowel obstruction. Results of synovial fluid cultures showed the presence of Gram-negative bacillus, Klebsiella pneumoniae and the CT scan images were highly suggestive of abdominal abscess within Crohn’s disease. The patient’s condition improved after following an antibiotic treatment and after the initiation of Anti-TNF-alpha agent Adalimumab, with no further exacerbation. Septic arthritis in Crohn’s disease should be considered to have a communicating source of sepsis consisting of an abdominal abscess or fistula.

    Staphylococcus aureus arthritis is a highly erosive disease in which both host and bacterial factors are of importance for its induction and progression. At the transcriptional level, three known loci act in regulating production of exoproteins and expression of cell wall structures. The aim of our study was to assess the role of the sar locus as a virulence determinant in the pathogenesis of septic arthritis. A recently established murine model of hematogenously spread S. aureus arthritis was employed. S. aureus strains, isogenic for the sar locus, were inoculated intravenously into NMRI mice, and the clinical, bacteriological, serological, and histopathological progression of the disease was studied. Within 1 week after inoculation of bacteria, the frequency of arthritis was 79% in the group of mice inoculated with the sar+ strain, whereas the corresponding frequency in sar mutants was 21% (P < 0.01). Mice inoculated with the sar+ staphylococcal strain exhibited a more pronounced T- and B-lymphocyte activation than those inoculated with the sar mutant, evidenced by splenomegaly, polyclonal B-cell activation, and high serum levels of interleukin 6 and gamma interferon. Also, infection with sar+ staphylococci induced a pronounced weight loss. To assess the relationship between clinical signs and spread of bacteria, we analyzed the homing pattern and persistence of S. aureus in host tissues. Kidneys and joints from sar+-inoculated subjects displayed a higher degree of bacterial persistence than other organs. Our results suggest that molecules controlled by the sar locus are important virulence determinants in the induction and progression of septic arthritis. PMID:8890189

    A 75-year-old man presented in shock secondary to septic arthritis of the knee. The patient, with a known history of knee osteoarthritis, was treated elsewhere for mechanical locking symptoms and effusion with arthroscopic debridement, and developed septic arthritis, which disseminated to the leg and foot after a tear in the capsule, and a ruptured pyogenic popliteal cyst. Open debridement of the knee joint, and drainage of the abscesses of the leg and foot, were performed. Antibiotic-loaded cement beads were left in the residual space. Debridement was repeated and cement beads removed after 4 days, and finally the infection was eradicated without any serious consequences for the patient. There is debate over arthroscopic intervention for osteoarthritic knees. The presence of a popliteal cyst, which is a rather common finding in the latter, could be related to a significant number of complications, such as septic arthritis.

    2016-04-01

    Septic arthritis of the temporomandibular joint (TMJ) has been infrequently reported in the literature. Some investigators believe that this condition is under-reported because it is underdiagnosed. Misdiagnosis or late diagnosis of this condition can lead to serious morbidity, including fistula formation, intracranial abscess, fibrous or bony ankylosis, temporal bone or condylar osteomyelitis, growth alteration, and several others. This report describes a case of septic TMJ arthritis arising from direct spread of an odontogenic infection with subsequent development of mandibular osteomyelitis. The purpose of this case report is to 1) increase awareness of an underdiagnosed condition, 2) establish the seriousness of this infection, 3) for the first time report on a case of TMJ septic arthritis caused by Bacteroides infection, and 4) provide a review of the relevant literature.

    There exist very few long-term follow-up studies, on total ankle replacement (TAR). In the present study a cohort of rheumatoid arthritic (RA) were followed for up to 23 years. Thirty-three TAR were performed in 26 RA patients from 1980 to 1993. Removal of the prostheses and radiolucency was considered endpoints. All patients were followed to prosthesis failure or until death of the patients or until January 2008. Two patients with 3 prostheses were still alive with their prosthesis in place. Eighteen patients with 23 prostheses had died with their prosthesis in place. Two patients had their ipsilateral leg amputated 12 and 14 years after operation of unrelated causes. Five prostheses in 4 patients had been removed. The 10 years prosthesis survival was 85%, when removal is the endpoint. The long-term survival of this first generation type of TAR adds some optimism to the development of TAR.

    Septic arthritis of the wrist is a diagnostic and therapeutic emergency. Synovectomy and lavage by arthrotomy is often followed by stiffness. The purpose of this study was to evaluate the diagnostic and therapeutic contribution of emergency arthroscopic synovectomy with intraarticular lavage. Nine patients were operated on for wrist pathology with septic appearance. All had signs of local inflammation, three showed locoregional inflammation, three were febrile. In one patient several joints were involved. Seven patients presented with inflammatory or degenerative arthritis. All patients underwent emergency surgery using radiocarpal joint puncture, arthroscopic exploration, intraarticular lavage and synovectomy at both the radiocarpal and midcarpal joints. The results were evaluated by pain, Quick DASH, grip strength, and wrist range of motion. In three cases, joint fluid appeared clear, in three it was turbid, and in three purulent. Gram stain and culture revealed bacteria in four cases. Synovitis was radiocarpal four times, radiocarpal and midcarpal once. In one case, there was radiocarpal and midcarpal chondritis. Average pain was 5.3/10 preoperatively and 2/10 at the last clinical follow-up visit. Mean grip strength was 23.3 kg on the involved side vs. 33.5 kg on the opposite one. Mean flexion was 55° for the involved wrist vs. 68°; mean extension was 52° for the affected wrist vs. 59°. No patient was reoperated on. In all cases, there was no sign of local inflammation, regional lymphadenopathy or systemic infection at the last follow-up. One patient died of colon metastatic cancer. Another patient developed a severe Complex Regional Pain Syndrome type I (CRPS1). Our results suggest three principles of management of wrist arthritis with septic appearance: extended surgical indication, emergency operation and arthroscopic procedure.

    The management of hip instability as a consequence of septic arthritis in childhood is difficult. Ilizarov hip reconstruction is a double-level femoral osteotomy with the objective of eliminating hip instability, through a proximal valgus-extension-derotation osteotomy and a distal varization-lengthening osteotomy for mechanical axis correction and equalization limb length. Ilizarov hip reconstruction was performed for 16 adult patients with complaints of hip pain, leg-length discrepancy, limping, reduced activity and limited abduction of the hip as a result of childhood septic arthritis. Their ages ranged from 19 to 32 years (mean 23.2 ± 4.2). Ilizarov external fixator was used in all cases. At the time of last follow-up that ranged from 60 to 132 months (mean 85.6 ± 23.5), the Harris hip score (HHS) showed excellent functional outcome in two cases (12.50 %), good in 13 cases (81.25 %) and fair in one case (6.25 %). There was no poor functional outcome in any case. Preoperatively, the mean HHS was 56.18 points, and at the time of last follow-up, it improved to a mean of 84.62 points. Pain subsided in all patients, the Trendelenburg sign became negative in all but three (19 %) patients, no patient had limb-length discrepancy, and the alignment of the extremity was reestablished in all cases. No additional operations were required. Ilizarov hip reconstruction is a valuable and durable solution for the late sequelae of childhood septic arthritis of the hip presenting in adult patients.

    OBJECTIVES: To clinically and epidemiologically characterize a population diagnosed with and treated for septic arthritis of the knee, to evaluate the treatment results and to analyze the differences between patients with positive and negative culture results, patients with Gram-positive and Gram-negative bacterial isolates and patients with S. aureus- and non-S. aureus-related infections. METHODS: One hundred and five patients with septic knee arthritis were included in this study. The clinical and epidemiological data were evaluated. Statistical analysis was performed to compare patients with and without an isolated causative agent, patients with Gram-positive and Gram-negative pathogens and patients with S. aureus-related and non S. aureus-related infections. RESULTS: Causative agents were isolated in 81 patients. Gram-positive bacteria were isolated in 65 patients and Gram-negative bacteria were isolated in 16 patients. The most commonly isolated bacterium was S. aureus. Comparing cases with an isolated pathogen to cases without an isolated pathogen, no differences between the studied variables were found except for the longer hospital stays of patients in whom an etiological agent was identified. When comparing Gram-positive bacteria with Gram-negative bacteria, patients with Gram-positive-related infections exhibited higher leukocyte counts. Patients with S. aureus-related infections were more frequently associated with healthcare-related environmental encounters. CONCLUSION: S. aureus is the most common pathogen of septic knee arthritis. Major differences were not observed between infections with isolated and non-isolated pathogens and between infections with Gram-positive and Gram-negative bacteria. S. aureus infections were more likely to be associated with a prior healthcare environment exposure. PMID:28076516

    Septic arthritis of the shoulder is very rarely caused by Aeromonas hydrophila. We present the case of a 45-year-old woman who presented with symptoms of painful shoulder for 2 weeks and dropped head for 1 week prior to admission. A. hydrophila was isolated from a culture of purulent synovial fluid. Magnetic resonance imaging revealed profuse abscess collection between the right infraspinatus muscle and trapezius muscle and swelling of the right and left paraspinatus muscles, which suggested myositis-related dropped head syndrome. After surgery with arthrotomy, function of the shoulder and neck extensors was significantly improved.

    There are aetiological, clinical, radiological and therapeutic differences between musculoskeletal infection in the neonate (and infant) and in older children and adults. Due to the anatomy and blood supply in neonates, osteomyelitis often co-exists with septic arthritis. Discitis is more common in infants whereas vertebral body infection is more common in adults. This review article discusses the important clinical and radiological differences that in the past have led many authors to consider neonatal osteomyelitis a separate entity from osteomyelitis in the older child.

    There is still controversy on the management of septic arthritis in neonates. This study aims to investigate the treatment of septic arthritis in neonates.We reviewed 52 neonates (37 males and 15 females) with septic arthritis in our hospital during 2004 to 2015. The mean age at onset of infection was 17.5 ± 7.6 days, mean age at admission was 32.6 ± 10.7 days. A total of 56 joints were involved (22 knees, 18 shoulders, 13 hips, and 3 other joints). Thiryt-six patients underwent surgical drainage, 14 patients were treated nonoperatively, 2 families refused treatment. Forty-four patients (48 joints) were followed for 4.5 ± 1.2 years. Based on treatment, these 48 joints were divided into an operative group and a nonoperative group. Clinical presentations, imaging examination results, treatments, and outcomes were analyzed.Among the patients who were followed-up, the time from onset to treatment in the operatively managed group (12.7 ± 8.1 days) was significantly shorter than that in the conservatively managed group (20.0 ± 8.2 days). There were no significant differences between both groups on the age at onset, age at admission, imaging score, length of hospital stay, WBC counts, and intravenous medication time. Thirty-five sites (72.9%) recovered completely. There was no significant difference on recovery rate between operative and nonoperative group. Only 33.3% of the hips recovered, this was significantly lower than that of knee/ankle (85.0%) and shoulder/elbow (78.9%). Sequels were found in 13 joints. Logistic regression indicated that sex, imaging score, and hip joint involvement were predictors of sequel. One point of imaging score increased the risk of sequels by a factor of 2.960, and hip joint involvement increased the risk of sequels by a factor of 12.712. Females were more likely to have sequels than males.Surgical drainage is recommended for early diagnosed neonatal septic arthritis and hip infections. A conservative approach may

    Ankylosis of the temporomandibular joint (TMJ) can be a result of several causes such as trauma, degenerative changes, infection, and space-occupying lesion. When occurring during early childhood, it can result in severe functional disability and facial deformity. Septic arthritis is an uncommon disease associated with systemic and local factors being most commonly caused by Staphylococcus aureus, Neisseria gonorrhoeae, and Haemophilus influenzae. This paper presents two unusual cases of TMJ ankylosis following neonatal infections treated surgically and does a literature review about the topic.

    This review describes the indications for surgical treatment of distal interphalangeal joint (DIJ) infection in cattle and presents an overview of former surgical methods that have been modified for current use, including arthrotomy, resection of the distal sesamoid bone, resection of the DIJ and digital amputation. The post-operative life span, reasons for culling, pros and cons of claw-preserving techniques versus digital amputation, and pain management in general are also discussed. It would appear that severe claw diseases that result in septic arthritis of the DIJ do not necessarily lead to a reduced life span if cows are adequately treated and thorough aftercare is provided.

    To evaluate the effect of arthroscopic lavage and repeated intra-articular administration of antibiotic in adult horses and foals with septic arthritis. Retrospective clinical study. Adult horses and foals with septic arthritis (n = 62). Age, sex, cause of septic synovitis, joint involved, hospitalization time, and outcome were recorded. Arthroscopic lavage was performed at day 0 (D 0). Synovial fluid was collected every 48 hours prior to intra-articular administration of antibiotic, and until hospital discharge. Synovial nucleated cell count, total protein, and percentage of neutrophils were compared across time and between subjects with a favorable or unfavorable outcome. Synovial nucleated cell counts decreased progressively and were lower at all times compared to D 0. Percentages of neutrophils were lower than baseline at D 8 and 10, only. Total protein contents decreased progressively and were lower than baseline at D 2, 4, 6, 8, 10, and 14. When adult horses and foals with a favorable outcome were compared to those with an unfavorable outcome, the nucleated cell count was lower at D 10, 12, and 14 and the percentage of neutrophils was lower at D 4 only, but total protein content did not differ between groups at any time. Synovial nucleated cell counts and total protein concentrations decreased after arthroscopic lavage and repeated intra-articular administration of antibiotic in horses and foals with septic arthritis. Synovial nucleated cell count is limited as a monitoring tool during treatment of septic arthritis. © 2017 The American College of Veterinary Surgeons.

    The Monotest Lactate Kit (MLT) was compared with gas-liquid chromatography (GLC) for the rapid detection of septic arthritis. A total of 36 joint fluids were tested. Specimens were obtained from patients with septic arthritis (17 cases), inflammatory arthritis (18 cases), and degenerative arthritis (1 case). Specimens from 15 patients with bacterial arthritis had lactate levels above 65 mg/dl (mean, 318 mg/dl with the GLC method and 378 mg/dl with the MLT method). Three specimens from patients with gonococcal arthritis had levels that were not above 30 mg/dl (mean, 21 mg/dl with either the GLC or the MLT methods). Patients with inflammatory or degenerative disease yielded levels lower than 65 mg/dl (mean, 48 mg/dl with the GLC method and 46 mg/dl with the MLT method). Both methods proved to be equallly reliable in detecting septic arthritis, except for the gonococcal cases. Both methods are fast and easily adaptable to clinical laboratories; however, MLT was more definitive when quantitation was needed, required less fluid per speciment, and could be readily done at the bedside.

    Matrix metalloproteinases (MMPs) are crucial players in Staphylococcus aureus mediated synovial tissue destruction in the pathogenesis of septic arthritis. Bacterial insult increases proteolytic matrix fragments by activated chondrocytes and synovial fibroblasts leading to induction of matrix metalloproteinases. Tissue destruction via MMPs induced by bacterial products, necrotic tissues and proinflammatory cytokines have been reported. Cytokines like TNF-α, IL-1β released from host cells in response to S. aureus infection promote cartilage degradation by stimulating the production of MMPs. Antibiotic treatment can eradicate invading bacteria but elevated levels of cytokines and cytokines induced MMPs activation lead to progressive and devastating bone and cartilage destruction even after bacterial clearance. Like other MMPs, MMP-2 also contributes to extracellular matrix degradation in different types of arthritis. Release of certain pro inflammatory cytokines can also be regulated by MMP-2 activation leading to further tissue destruction. The role of MMP-2 in the pathogenesis of S. aureus infection induced septic arthritis and its influence on cytokines regulation needs further investigation. Whether neutralization of MMP-2 provides protection against Staphylococcus aureus infection induced septic arthritis in mice is an obvious question. Here we reported that neutralization of MMP-2 during S. aureus infection induced septic arthritis might be beneficial for preventing infection induced extracellular matrix destruction thereby decreasing bacterial burden in synovial tissues and regulating inflammatory cytokines in arthritic mice.

    Objective Rheumatoid arthritis often results in deformities at the metacarpophalangeal (MCP) joint. Patients with severe deformities can be treated by silicone metacarpophalangeal joint arthroplasty (SMPA). The objective of the study is to prospectively compare long-term outcomes for a SMPA surgical and a non-surgical cohort of rheumatoid arthritis patients. Methods A total of 67 surgical and 95 nonsurgical patients with severe subluxation and/or ulnar drift of the fingers at the MCP joints were recruited from 2004-2008 in this multi-center prospective cohort study. Patients could elect to undergo SMPA or not. Outcomes included the Michigan Hand Outcomes Questionnaire (MHQ), Arthritis Impact Measurement Scales (AIMS2), grip/pinch strength, Jebson-Taylor test and ulnar deviation, extensor lag and arc of motion measurements at the MCP joints. Results There was no significant difference in the mean age, race, education, and income at baseline between the two groups. Surgical subjects had worse MHQ function and functional measurements at baseline. At 3 years, the mean overall MHQ score and the MHQ function, activities of daily living, aesthetics and satisfaction scores showed significant improvement in the surgical group compared to the non-surgical group. Ulnar deviation, extensor lag and arc of motion in the MCP and PIP joints also improved significantly in the surgical group. No improvement was seen in the mean AIMS2 scores and grip/pinch strength. Complications were minimal with a fracture rate of 9.5%. Conclusion RA patients with poor baseline functioning showed long term improvement in hand function and appearance following treatment with SMPA compared to non-surgical controls. PMID:22511483

    To evaluate the efficacy and safety of the biosimilar infliximab in adult patients with inflammatory arthritis switched from reference product in our center. In April 2014, patients attending our rheumatology service for infliximab infusions were switched from reference product to the biosimilar infliximab following consent and hospital approval. Around 34 patients with inflammatory arthritis were switched from reference product to biosimilar infliximab in 2014: 50% female, mean age 55 years (standard deviation=12.9), mean disease duration 14.79 years (9.7), median duration on infliximab 57 months, and two-thirds on oral disease-modifying antirheumatic drugs. There was no difference in efficacy or safety in the first 6 months of therapy. By the end of 2015, the mean follow-up on biosimilar infliximab was 15.8 (standard deviation=6.3) months. Our results showed no significant difference in Health Assessment Questionnaire score, patient global assessment of disease activity, number of disease flares, or the medication dose between the originator and the biosimilar infliximab. However, reported pain and C-reactive protein values were significantly higher during the longer follow-up period (p=0.043, 0.001 respectively). There was no significant difference in the number of adverse events or infusion reactions during follow-up periods. Only five (14.7%) patients discontinued the biosimilar infliximab. Our patients experienced similar efficacy and safety for managing their arthritis with the biosimilar infliximab as the reference product infliximab, but at a much lower cost.

    Septic arthritis is a clinical emergency requiring prompt diagnosis and treatment to avoid significant morbidity and mortality. Polyarticular septic arthritis (PASA) accounts for 15% of all infectious arthritides and rarely occurs in immunocompetent adults. Staphylococcus aureus is the most commonly isolated organism, with infection primarily affecting knees, shoulders, elbows, and hips. The morbidity associated with PASA is very high, and mortality in treated cases of PASA may be as high as 50% of cases. We report a case of PASA with associated epidural abscess in a healthy adult male, who presented with complaints of arthralgia and limited range of motion of his left shoulder, wrist, and ankle. He also presented with low back pain and motor weakness associated with an epidural abscess spanning L2-S1, with multilevel vertebral osteomyelitis. Surgical washout of the affected joints as well as decompressive laminectomies was performed, and he received a standard course of intravenous antibiotics. Staphylococcus aureus was isolated from joint aspirations and from blood cultures. The patient had a full neurological and functional recovery postoperatively with no sequelae. To the best of our knowledge this is the only case report of Staphylococcus aureus PASA with concomitant epidural abscess in an immunocompetent adult. PMID:26146580

    A 5.5-y-old Chinese-origin female rhesus macaque (Macaca mulatta) presented for bilateral hindlimb lameness. The primate had been group-reared in an SPF breeding colony and was seronegative for Macacine herpesvirus 1, SIV, simian retrovirus type D, and simian T-lymphotropic virus. The macaque's previous medical history included multiple occasions of swelling in the left tarsus, and trauma to the right arm and bilateral hands. In addition, the macaque had experienced osteomyelitis of the left distal tibia and rupture of the right cranial cruciate ligament that had been surgically repaired. Abnormal physical examination findings on presentation included a thin body condition, mild dehydration, and bilaterally swollen stifles that were warm to the touch, with the right stifle more severely affected. Mild instability in the left stifle was noted, and decreased range of motion and muscle atrophy were present bilaterally. Hematologic findings included marked neutrophilia and lymphopenia and moderate anemia. Arthrocentesis and culture of joint fluid revealed Moraxella-like organisms. Treatment with enrofloxacin was initiated empirically and subsequently switched to cephalexin, which over time alleviated the joint swelling and inflammation. Definitive diagnosis of Moraxella osloensis septic arthritis was made through isolation of the organism and sequencing of the 16S rDNA region. To our knowledge, this report is the first description of Moraxella osloensis septic arthritis in a rhesus macaque.

    Arthrodesis was performed to treat septic arthritis of the proximal interphalangeal joint of 8 horses. Records of the horses were reviewed to determine outcome and possible factors that influenced success or failure. All horses were female. Seven horses had 1 joint treated and 1 horse was treated for bilateral pelvic limb involvement. The duration of sepsis before surgery ranged from 1 to 66 days. Bone lysis and production was radiographically apparent in 7 horses before surgery. Six horses had multiple bacterial organisms cultured from bone or synovial tissues; 2 horses had single isolates identified. After aggressive curettage, arthrodesis was accomplished with 3 parallel screws in 1 horse, 2 divergent narrow dynamic compression plates in 3 horses, and a single broad dynamic compression plate in 4 horses. Casts were applied to all horses for 1 to 6 weeks. Four horses survived to successful brood mare status. Four horses were euthanized during hospitalization because of continued discomfort or complications of sepsis. Arthrodesis of the proximal interphalangeal joint affected with septic arthritis appears to be an acceptable alternative to euthanasia for some horses. Images Figure 1. Figure 2. Figure 3. Figure 4.

  11. Osteomyelitis/septic arthritis caused by Kingella kingae among day care attendees--Minnesota, 2003.

    PubMed

    2004-03-26

    Kingella kingae is a fastidious gram-negative coccobacillus that colonizes the respiratory and oropharyngeal tract in children. K. kingae occasionally causes invasive disease, primarily osteomyelitis/septic arthritis in young children, bacteremia in infants, and endocarditis in school-aged children and adults. Although diagnosis of this organism frequently is missed, invasive disease is uncommon. Only sporadic, non-epidemiologically linked cases have been reported previously. In October 2003, the Minnesota Department of Health (MDH) investigated a cluster of two confirmed cases and one probable case of osteomyelitis/septic arthritis caused by K. kingae among children aged 17-21 months attending the same toddler classroom in a day care center. All reported within the same week with onset of fever, preceding or concurrent upper respiratory illness (URI), and refusal to bear weight on the affected limb. This report summarizes these cases and describes the epidemiologic investigation of the day care center. The findings underscore the need for clinicians and laboratorians to consider K. kingae infection in young children with Gram stain--negative or culture-negative skeletal infections.

    Purpose To evaluate the efficacy and safety of the biosimilar infliximab in adult patients with inflammatory arthritis switched from reference product in our center. Patients and methods In April 2014, patients attending our rheumatology service for infliximab infusions were switched from reference product to the biosimilar infliximab following consent and hospital approval. Results Around 34 patients with inflammatory arthritis were switched from reference product to biosimilar infliximab in 2014: 50% female, mean age 55 years (standard deviation=12.9), mean disease duration 14.79 years (9.7), median duration on infliximab 57 months, and two-thirds on oral disease-modifying antirheumatic drugs. There was no difference in efficacy or safety in the first 6 months of therapy. By the end of 2015, the mean follow-up on biosimilar infliximab was 15.8 (standard deviation=6.3) months. Our results showed no significant difference in Health Assessment Questionnaire score, patient global assessment of disease activity, number of disease flares, or the medication dose between the originator and the biosimilar infliximab. However, reported pain and C-reactive protein values were significantly higher during the longer follow-up period (p=0.043, 0.001 respectively). There was no significant difference in the number of adverse events or infusion reactions during follow-up periods. Only five (14.7%) patients discontinued the biosimilar infliximab. Conclusion Our patients experienced similar efficacy and safety for managing their arthritis with the biosimilar infliximab as the reference product infliximab, but at a much lower cost.

    To analyze the changes in health-related quality of life (HRQoL) of patients with rheumatoid arthritis (RA) treated with biological therapies. Observational prospective study performed from October 2006 to May 2011. The inclusion criteria were adult patients, diagnosed with RA, treated for at least one year with anti-tumor necrosis factor therapy (infliximab or etanercept), who had not received other biological treatments previously. A total of 41 patients who completed the study undertook the specific and validated questionnaire QoL-RA Scale 3 times: E1 (September 2006-February 2007), E2 (April 2008-January 2009) and E3 (July 2010- May 2011). Data analysis was conducted using Epi-Info version 3.3 2004 for Windows® and Excel 2007; mean comparisons were evaluated by Student's t-test and the relationship between the 3 outcomes for each patient by lineal regression. Overall results show a downward trend which was not statistically significant: 7.09 (standard deviation [SD]=1.15) in E1; 6.90 (SD=1.60) in E2; and 6.52 (SD=1.59) in E3. Items with higher scores were those related to psychosocial aspects (help from family, interaction with family and friends), whereas the physical dimension was valued more poorly (physical ability, arthritis pain, arthritis). Between E2 and E3 there was a significant increase in help from family (P=.0008), whereas level of tension (P=.0119) and mood (P=.0451) decreased significantly. In all, HRQoL reported by patients is good and has remained unchanged after approximately 6 years of study. The stability of HRQoL is probably partly attributable to treatment.

    Large epidemiologic studies have associated gouty arthritis with the risk of coronary heart disease. However, there has been a lack of information regarding the outcomes for patients who have gout attacks during hospitalization for acute myocardial infarction. We reviewed the data of 444 consecutive patients who were admitted to our hospital between 2005 and 2008 due to acute ST elevation myocardial infarction (STEMI). The clinical outcomes were compared between patients with gout attack and those without. Of the 444, 48 patients with acute STEMI developed acute gouty arthritis during hospitalization. The multivariate analysis identified prior history of gout and estimated glomerular filtration rate as independent risk factors of gout attack for patients with acute STEMI (odds ratio (OR) 21.02, 95 % CI 2.96-149.26, p = 0.002; OR 0.92, 95 % CI 0.86-0.99, p = 0.035, respectively). The in-hospital mortality and duration of hospital stay did not differ significantly between the gouty group and the non-gouty group (controls). During a mean follow-up of 49 ± 28 months, all-cause mortality and stroke were similar for both groups. Multivariate Cox regression showed that gout attack was independently associated with short- and long-term adverse non-fatal cardiac events (hazard ratio (HR) 1.88, 95 % CI 1.09-3.24, p = 0.024; HR 1.82, 95 % CI 1.09-3.03, p = 0.022, respectively). Gout attack among patients hospitalized due to acute STEMI was independently associated with short-term and long-term rates of adverse non-fatal cardiac events.

    We previously reported that administration of an adeno-associated virus 2 (AAV2) vector encoding a rat tumor necrosis factor (TNF) receptor-immunoglobulin Fc (TNFR:Fc) fusion gene to rats with streptococcal cell wall-induced arthritis resulted in suppression of joint inflammation and cartilage and bone destruction, as well as expression of joint proinflammatory cytokines. In this study, we used an alternate rat model of arthritis to compare the serum levels and duration of TNFR:Fc protein expression following intramuscular administration of pseudotyped AAV-TNFR:Fc vectors based on serotypes 1, 2, and 5. All three pseudotyped AAV-TNFR:Fc vectors led to sustained expression of serum TNFR:Fc protein for at least one year. Serum TNFR:Fc protein levels in rats administered intramuscularly with AAV2/1-TNFR:Fc vector were up to 100- and 10-fold higher than in rats administered the AAV2-TNFR:Fc or AAV2/5-TNFR:Fc vectors, respectively. A single intramuscular administration of AAV2/1-TNFR:Fc vector at vector doses ranging from 10(10) to 10(12) DNase-resistant particles (DRP) per animal, resulted in complete and long-term suppression of recurrent joint inflammation for at least 150 days. Our results establish a proof of concept for administration of an AAV2/1-TNFR:Fc vector to the muscle to achieve long-term, sustained and therapeutically relevant levels of TNFR:Fc protein to treat chronic systemic inflammatory joint diseases.

    We report the first case of both endocarditis and bilateral septic arthritis in a patient caused by Moraxella lacunata and successful management of the infection with antimicrobial therapy. The route of entry leading to bacteremia may have been the oral cavity given the poor oral hygiene of the patient as evidenced by bleeding gums. We hypothesize that the bacteremia led to septic arthritis and mitral valve infective endocarditis. In this case report, we also review the literature on M. lacunata infections and conclude that this organism should be considered in bilateral septic arthritis in a patient with underlying heart abnormalities and/or with renal failure.

    Effects of ampicillin (Amp) in combination with riboflavin on septic arthritis in mice infected with Staphylococcus aureus have been reported. Ampicillin was given at 100 mg/kg after 24 h of infection, followed by riboflavin (Ribo) at 20 mg/kg body wt, after 2 h of Amp treatment. Mice were sacrificed at 3, 9, 15 days post infection (dpi). Combined treatment of infected mice with ampicillin and riboflavin eradicated the bacteria from blood, spleen and synovial tissue and showed a significant gross reduction in arthritis, reduced serum levels of TNF-alpha and IFN-gamma. S. aureus infected mice exhibited higher synovial TNF-alpha and IL-6, which was also reduced by ampicillin and riboflavin treatment. S. aureus infected mice showed a disturbed antioxidant status measured in terms of cellular anti-oxidants like reduced glutathione and anti-oxidant enzymes such as superoxide dismutase and catalase and were ameliorated when the animals were co-treated with ampicillin along with riboflavin. Results of the study showed that combined treatment with anti-oxidant and antibiotic may protect from staphylococcal arthritis and may ameliorate oxidative stress caused by S. aureus infection.

  18. Surgical Management of Multijoint Septic Arthritis due to Rat-Bite Fever in a Pediatric Patient: A Case Study

    In the United States, rat-bite fever is a rare systemic illness principally caused by Streptobacillus moniliformis, an organism found in the nasopharyngeal flora of rodents. Infection through direct exposure to rat excreta such as saliva, urine, or feces can lead to fever, rash, and an asymmetric migratory polyarthritis. As rodents are becoming more popular as pets, more pediatric cases are being documented. We report a pediatric case of delayed onset septic arthritis in the left wrist and right knee due to S. moniliformis from a rat bite. Previously reported pediatric case studies of suppurative arthritis due to S. moniliformis have only involved the hip. This case study demonstrates the importance of a thorough exposure history and consideration of zoonotic infections as a cause of septic arthritis in a pediatric patient that requires antibiotics and surgical intervention.

    Life-table analysis was applied to the records of 317 patients with rheumatoid arthritis (RA) treated with sulphasalazine (SAS), 201 treated with sodium aurothiomalate (gold), and 163 with penicillamine. They comprised all those treated in our department with these drugs between January 1973 and July 1984. Risks of treatment termination for all reasons were similar for each drug at five years (gold 92%, penicillamine 83%, SAS 81%). The risk of treatment termination due to inefficacy was less for gold (29.5%) than for penicillamine (38.1%) or sulphasalazine (41.2%). Adverse effects, however, led to withdrawal of gold in 57%, penicillamine in 41.2%, and SAS in 37%; the most effective drugs appeared most toxic. Serious adverse effects were much more common in association with gold (17.4%) and penicillamine (12.3%) than with SAS (1.6%). Sulphasalazine appears as well tolerated over long periods in RA as gold or penicillamine and is associated with fewer serious adverse effects; of these drugs, it might therefore be considered the agent of first choice.

    An osteosclerosis opacifying the axial skeleton and affecting in particular all of the spine, was observed in two women aged 75 and 42 years who had been suffering from a rheumatoid arthritis developing between 15 and 26 years. It was traced to a chronic fluorine intoxication, stemming from the regular taking, for 10 years and 8 1/2 years, of a non cortisone, anti-inflammatory niflumic acid. This fluorine product has 3 atoms of fluor in its molecule (50.0 mg for a tablet of 250 mg). Its administration to control subjects proved the production of ionized fluor by way of the metabolism, and the accumulation of fluor in the organism. Rheumatoid polyarthritis and the prolonged corticotherapy (10 mg of prednisone per day for 21 years) cannot be dismissed as the origin of the severe demineralization of the limbs observed in the second patient, but the role of fluorine seems marked in the occurrence of this peripheral involvement with problems of mineralization and secondary hyperparathyroidisms. On the other hand, the absence of an intervertebral narrowing in the 2 patients, despite the very prolonged taking of cortisone (5 mg of prednisone per day for 15 years, for the 75-year-old patient) is perhaps a result of the fluorine.

    Lancefield group G streptococci (GGS) are a relatively less common cause of streptococcal infections but the incidence of which has been reported to increase in the recent years. Similar to group A streptococci, GGS produce localised and invasive infections. Streptococcal myositis is a very rare but highly fatal infection of muscles generally caused by group A streptococci. We report a case of sepsis, migrating septic arthritis and diffuse myositis caused by β-haemolytic GGS. It is an unusual case of diffuse β-haemolytic GGS myositis involving multiple muscle groups in a patient who demonstrated no skin lesions or sign of streptococcal toxic shock syndrome. The patient responded well to intravenous antibiotics without surgical intervention and experienced full recovery. PMID:24469838

    We report a case of a prosthetic joint infection occurring secondary to group C Streptococcus following dental treatment in a 66-year-old woman. This patient presented 11 years following a right hip resurfacing procedure with increasing pain and difficulty mobilising the right hip. An ultrasound and MRI scan identified a collection in the right hip joint, which was subsequently aspirated. Cultures revealed a group C Streptococcus. Extensive washout and surgical debridement of the hip joint was undertaken and the patient was treated with a protracted course of antibiotics. At 1 year follow-up, the patient demonstrated no evidence of recurrent infection. We discuss the evidence underlying prophylactic antibiotic usage regarding dental procedures in the prevention of septic arthritis in patients with prosthetic joints. We also review the spectrum of diseases caused by this organism.

    Macrophages are key-cells in the initiation, the development and the regulation of the inflammatory response to bacterial infection. Macrophages are intensively and increasingly recruited in septic joints from the early phases of infection and the infiltration is supposed to regress once efficient removal of the pathogens is obtained. The ability to identify in vivo macrophage activity in an infected joint can therefore provide two main applications: early detection of acute synovitis and monitoring of therapy. In vivo noninvasive detection of macrophages can be performed with magnetic resonance imaging using iron nanoparticles such as ultrasmall superparamagnetic iron oxide (USPIO). After intravascular or intraarticular administration, USPIO are specifically phagocytized by activated macrophages, and, due to their magnetic properties, induce signal changes in tissues presenting macrophage infiltration. A quantitative evaluation of the infiltrate is feasible, as the area with signal loss (number of dark pixels) observed on gradient echo MR images after particles injection is correlated with the amount of iron within the tissue and therefore reflects the number of USPIO-loaded cells. We present here a protocol to perform macrophage imaging using USPIO-enhanced MR imaging in an animal model of septic arthritis, allowing an initial and longitudinal in vivo noninvasive evaluation of macrophages infiltration and an assessment of therapy action.

    Septic arthritis in infants is rare and can be difficult to diagnose. This study reviewed a series of patients younger than 3 months to identify factors that may assist in early diagnosis and treatment. A query of records at a large Midwestern pediatric hospital (1994-2010) was performed to identify all patients younger than 3 months at the time of diagnosis. Analysis included birth history, joint involvement, physical examination findings, laboratory results, imaging results, method of treatment, and outcome. In 14 cases (11 boys, 3 girls; mean age at diagnosis, 42.2 days), complete records were available for review. Involved joints included the knee, hip, and shoulder. The most common findings on physical examination were decreased range of motion (100%), tenderness (100%), and swelling (71.4%). Mean temperature was 38.5°C. Mean white blood cell count was 18.5 K/µL, mean erythrocyte sedimentation rate was 48.9 mm/h, and mean C-reactive protein level was 6.1 mg/dL. More than half (57.1%) of joint aspirates grew positive cultures, and 41.7% of blood cultures had positive results. Causative organisms were group B streptococcus, methicillin-sensitive Staphylococcus aureus, Haemophilus influenzae, Streptococcus pneumoniae, Salmonella enterica, and Candida albicans. The most common physical examination findings in infants younger than 3 months with septic arthritis include tenderness, decreased range of motion, and swelling. White blood cell count, C-reactive protein level, and erythrocyte sedimentation rate are likely to be elevated, but these findings should be used in combination with findings on physical examination and radiographic studies to aid in diagnosis.

    Septic arthritis of the atlantoaxial facet joint is extremely rare. Contiguous spread to the median atlantoaxial joints with subsequent dens erosion can lead to atlantoaxial instability. Misleading normal inflammatory markers can result in delayed diagnosis and catastrophic consequences. A 56-year-old man presented with right-sided neck pain that had lasted for 2 days. He did not have fever or chills, and his serum C-reactive protein and erythrocyte sedimentation rate were normal. The patient was diagnosed with acute neck strain and treated conservatively. The pain continued for the next 3 weeks; cervical spine radiographs demonstrated normal findings with the exception of degenerative changes. The patient was treated with physical rehabilitation for the presumed neck strain and degenerative changes of the cervical vertebrae. Worsening neck pain and stiffness prompted a magnetic resonance imaging study obtained 5 weeks after the initial presentation, which showed an epidural collection with septic arthritis of the right facet and median atlantoaxial joints. Computed tomography demonstrated severe dens erosion. Surgical evacuation of the abscess and occipitocervical fusion were performed. Pathologic evaluation of tissue obtained during surgery demonstrated the presence of an infection, and Streptococcus anginosus grew from cultures. Infection must be considered in the differential diagnosis for neck pain when imaging findings are suggestive of an infectious process, even in an afebrile patient with normal C-reactive protein and erythrocyte sedimentation rate levels. Magnetic resonance imaging and computed tomography can play a critical role in such cases, potentially leading to a more timely diagnosis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Objectives: To assess the impact of increased number of diagnostic and therapeutic joint procedures on the incidence and type of septic arthritis (SA). Methods: All cases of SA in Iceland from 1990–2002 were identified by thorough review of the available medical information. The results of synovial fluid cultures from every microbiology department in Iceland were checked and positive culture results reviewed, as well as patient charts with a discharge diagnosis of septic arthritis (International Statistical Classification of Diseases and Related Health Problems (ICD) code M009). Results: A total of 253 cases of SA (69 children and 184 adults) were diagnosed in Iceland in 1990–2002, giving an average incidence of 7.1 cases/100 000 inhabitants. The incidence of SA increased from 4.2 cases/100 000 in 1990 to 11.0 cases/100 000 in 2002. This rise in SA was primarily observed in adults where the incidence rose by 0.61 cases/100 000 per year (p<0.001). SA was iatrogenic in 41.8% of adults and the number of iatrogenic infections increased from 2.8 cases/year in 1990–1994 to 9.0 cases/year in 1998–2002 (p<0.01). The annual number of arthroscopies increased from 430 in 1990–1994 to 2303 in 1998–2002 (p<0.001) and there was a correlation between the total usage of intra-articular drugs in Iceland and the incidence of SA (p<0.01). The frequency of post-arthroscopy SA was 0.14% and post-arthrocentesis SA 0.037%. Conclusions: The incidence of SA has increased in recent years due to an increased number of arthroscopies and joint injections. Although the frequency of SA per procedure has not changed, these results emphasise the importance of sterile technique and firm indications for joint procedures. PMID:17901088

    The Combinatietherapie Bij Reumatoide Artritis (COBRA) trial demonstrated that step-down combination therapy with prednisolone, methotrexate, and sulfasalazine (SSZ) was superior to SSZ monotherapy for suppressing disease activity and radiologic progression of rheumatoid arthritis (RA). The current study was conducted to investigate whether the benefits of COBRA therapy were sustained over time, and to determine which baseline factors could predict outcome. All patients had participated in the 56-week COBRA trial. During followup, they were seen by their own rheumatologists and were also assessed regularly by study nurses; no treatment protocol was specified. Disease activity, radiologic damage, and functional ability were the primary outcome domains. Two independent assessors scored radiographs in sequence according to the Sharp/van der Heijde method. Outcomes were analyzed by generalized estimating equations on the basis of intent-to-treat, starting with data obtained at the last visit of the COBRA trial (56 weeks after baseline). At the beginning of followup, patients in the COBRA group had a significantly lower mean time-averaged 28-joint disease activity score (DAS28) and a significantly lower median radiologic damage (Sharp) score compared with those in the SSZ monotherapy group. The functional ability score (Health Assessment Questionnaire [HAQ]) was similar in both groups. During the 4-5 year followup period, the time-averaged DAS28 decreased 0.17 points per year in the SSZ group and 0.07 in the COBRA group. The Sharp progression rate was 8.6 points per year in the SSZ group and 5.6 in the COBRA group. After adjustment for differences in treatment and disease activity during followup, the between-group difference in the rate of radiologic progression was 3.7 points per year. The HAQ score did not change significantly over time. Independent baseline predictors of radiologic progression over time (apart from treatment allocation) were rheumatoid factor

    Background Epstein-Barr Virus (EBV) is a widely disseminated lymphotropic herpes virus implicated in benign and malignant disorders. In transplant patients, immunosuppressive drugs (cyclosporine) diminish control of EBV replication, potentially leading to lymphoproliferative disorders (LPD). Rheumatoid arthritis (RA) patients have impaired control of EBV infection and have EBV load ten times higher than controls. As post transplant patients, patients with RA have increased risk of developing lymphomas. Immunosuppressive drugs used to treat RA (conventional disease modifying drugs cDMARDs or biologics bDMARDs) could enhance the risk of developing LPD in RA patients. We have previously shown that long term treatment with Methotrexate and/or TNF alpha antagonists does not increase EBV load in RA. Our objective was to monitor the Epstein-Barr Virus load in RA patients treated with Abatacept (CTLA4 Ig), a T cell coactivation inhibitor, and Tocilizumab, an anti IL6 receptor antibody. Methods EBV load in the peripheral blood mononuclear cells (PBMCs) of 55 patients under Abatacept (in 34% associated with Methotrexate) and 35 patients under Tocilizumab (in 37% associated with Methotrexate) was monitored for durations ranging from 6 months to 3 years by real time PCR. The influences of treatment duration and disease activity score 28 (DAS28) index on EBV load were analyzed. Results Abatacept did not significantly modify EBV load over time. Tocilizumab significantly diminished EBV load over time. No patient (of 90) developed EBV associated lymphoma. Conclusion Long term treatment with Abatacept or Tocilizumab does not increase EBV load in the PBMNCs of patients with RA. PMID:28199343

    Objective To describe changes in immune parameters observed during long-term methotrexate (MTX) therapy in patients with active rheumatoid arthritis (RA) and explore correlations with simultaneously measured MTX pharmacokinetic (PKC) parameters. Design Prospective, open-label, long-term mechanism of action study. Setting University clinic. Methods MTX was initiated at a single weekly oral dose of 7.5 mg and dose adjusted for efficacy and toxicity for the duration of the study. Standard measures of disease activity were performed at baseline and every 6–36 months. Serum cytokine measurements in blood together with lymphocyte surface immunophenotypes and stimulated peripheral blood mononuclear cell (PBMC) cytokine production were assessed at each clinical evaluation. Results Cytokine concentrations exhibited multiple significant correlations with disease activity measures over time. The strongest correlations observed were for interleukin (IL)-6 (r=0.45, p<0.0001 for swollen joints and r=0.32, p=0.002 for tender joints) and IL-8 (r=0.25, p=0.01 for swollen joints). Significant decreases from baseline were observed in serum IL-1B, IL-6 and IL-8 concentrations. The most significant changes were observed for IL-6 (p<0.001). Significant increases from baseline were observed in IL-2 release from PBMCs ex vivo (p<0.01). In parallel, multiple statistically significant correlations were observed between MTX PKC measures and immune parameters. The change in swollen joint count correlated inversely with the change in area under the curve (AUC) for MTX (r=−0.63, p=0.007). Conclusions MTX therapy of patients with RA is accompanied by a variety of changes in serum cytokine expression, which in turn correlate strongly with clinical disease activity and MTX pharmacokinetics (PKCs). These data strongly support the notion that MTX mediates profound and functionally relevant effects on the immunological hierarchy in the RA lesion. PMID:27335660

    To analyse the association between dietary long-chain n-3 polyunsaturated fatty acids (PUFAs) and incidence of rheumatoid arthritis (RA) in middle-aged and older women from the Swedish Mammography Cohort, a population-based prospective study. Data on diet were collected in 1987 and 1997 via a self-administered food-frequency questionnaire (FFQ). The risk of RA associated with dietary long-chain n-3 PUFAs and fish intake was estimated using Cox proportional hazard regression models, adjusted for age, cigarette smoking, alcohol intake, use of aspirin and energy intake. Among 32 232 women born 1914-1948, 205 RA cases were identified during a mean follow-up of 7.5 years (1 January 2003 to 31 December 2010; 2 41 120 person-years). An intake of dietary long-chain n-3 PUFAs (FFQ1997) of more than 0.21 g/day (lowest quintile) was associated with a 35% decreased risk of developing RA (multivariable adjusted relative risk (RR) 0.65; 95% CI 0.48 to 0.90) compared with a lower intake. Long-term intake consistently higher than 0.21 g/day (according to both FFQ1987 and FFQ1997) was associated with a 52% (95% CI 29% to 67%) decreased risk. Consistent long-term consumption (FFQ1987 and FFQ1997) of fish ≥1 serving per week compared with<1 was associated with a 29% decrease in risk (RR 0.71; 95% CI 0.48 to 1.04). This prospective study of women supports the hypothesis that dietary intake of long-chain n-3 PUFAs may play a role in aetiology of RA. Published by the BMJ Publishing Group Limited.

    A 6-week-old, parent-reared peregrine falcon ( Falco peregrinus ) was presented with spastic hypertonus of its hind limbs of unknown origin and duration. Radiologic examination revealed smooth periosteal reactions ventrally at thoracic vertebrae 5 to 7. Contrast-enhanced computed tomography identified the swelling as inflammation; antibiotic, antimycotic, anti-inflammatory, and analgesic treatments were initiated, and vitamins and minerals were supplemented. Because the bird's condition did not improve after 10 days, it was euthanatized and submitted for postmortem examination. On histopathologic examination, chronic, active osteomyelitis was diagnosed in thoracic vertebrae 5 to 7, and chronic, active arthritis was present in both the right shoulder and left elbow joints. Staphylococcus hyicus was isolated from these 3 locations, as well as from lungs and liver, indicating a chronic septic staphylococcosis. Although infections with Staphylococcus species are occasional causes of vertebral osteomyelitis in juvenile poultry with active growth plates, it is only sporadically reported in raptors and companion birds. This case report is the first description of the clinical features and diagnostic and pathologic findings in a juvenile peregrine falcon with hematogenous osteomyelitis and arthritis associated with septicemia caused by S hyicus.

    To investigate in a randomized clinical trial setting with an aggressive combination-therapy arm and a mild-monotherapy arm, whether therapy-induced changes in urinary C-terminal crosslinking telopeptide of type I collagen (CTX-I) and type II collagen (CTX-II) predict 5-year radiographic progression in patients with rheumatoid arthritis (RA). Patients had participated in the COBRA (Combinatietherapie Bij Reumatoïde Artritis) trial comparing aggressive step-down combination therapy (the COBRA regimen, including temporary high-dose prednisolone, temporary low-dose methotrexate, and sulfasalazine [SSZ]) and mild monotherapy (SSZ). Urinary CTX-I and CTX-II levels were measured at baseline and 3, 6, 9, and 12 months after initiation of treatment. Radiographs were scored according to the modified Sharp/van der Heijde method (mean of 2 independent readers who were aware of the sequence). Individual long-term radiographic progression was estimated, using baseline radiographs and all radiographs obtained during the followup period, by simple linear regression analysis (curve fitting). Both COBRA therapy and SSZ monotherapy produced a significant decrease in urinary CTX-I and CTX-II levels at 3 months, and this decrease was amplified at 6 months. COBRA therapy suppressed CTX-II (change from baseline levels -36% and -43% at 3 and 6 months, respectively), but not CTX-I, significantly better than did SSZ (-17% and -21% at 3 and 6 months, respectively) at 3 and 6 months. The magnitude of the decrease in urinary CTX-II levels at 3 months significantly predicted long-term (5-year) radiographic progression (beta = 0.48 [95% confidence interval (95% CI) 0.13, 0.83]). This effect was independent of the change in disease activity and inflammation indices at 3 months. Patients whose CTX-II levels were normalized (<150 ng/mmoles of urinary creatinine) at 3 months had a significantly higher chance of radiographic stability (no progression over 5 years) than did patients whose CTX

    Introduction: Immune system is involved in the etiology and pathophysiology of inflammation and vitamins are important sources of substances inducing nonspecific immunomodulatory effects. Given the proinflammatory role of cytokines in the inflammation and pain induction, this study aimed to assess the effects of long-term administration of vitamin B1 on the proinflammatory cytokines, edema, and hyperalgesia during the acute and chronic phases of adjuvant-induced arthritis. Methods: On the first day of study, inflammation was induced by intraplantar injection of complete Freund's adjuvant (CFA) in the hindpaws of rats. Vitamin B1 at doses of 100, 150, and 200 mg/kg was administrated intraperitoneally during 21 days of the study. Antinociceptive and anti-inflammatory effects of vitamin B1 were also compared to indomethacin (5 mg/kg). Inflammatory symptoms such as thermal hyperalgesia and paw edema were measured by radiant heat and plethysmometer, respectively. Serum TNF-α and IL-1β levels were checked by rat standard enzyme-linked immune sorbent assay (ELISA) specific kits. Results: The results indicated that vitamin B1(150 and 200 mg/kg) attenuated the paw edema, thermal hyperalgesia, and serum levels of TNF-α and IL-1β during both phases of CFA-induced inflammation in a dose-dependent manner. Effective dose of vitamin B1(150 mg/kg) reduced inflammatory symptoms and serum levels of TNF-α and IL-1β compare to indomethacin during the chronic phase of inflammation. Conclusion: Anti-inflammatory and antihyperalgesic effects of vitamin B1 during CFA-induced arthritis, more specifically after chronic vitamin B1 administration, suggest its therapeutic property for inflammation.

    We describe a 21-year-old man with a large osteochondral defect of the knee after septic arthritis, successfully treated by transplant of mesenchymal stem cells (MSC) from bone marrow and a new type of interconnected porous hydroxyapatite ceramic (IP-CHA). We confirmed successful cartilage-like tissue regeneration by a second arthroscopy. Biopsy of the repaired tissue revealed cartilage-like regeneration and bone formation. We were able to regenerate new bone and cartilage-like tissue in a one-stage operation, without sacrificing autologous bone or other tissue. This cultured MSC and IP-CHA hybrid material transplant represents a novel treatment for a severe osteochondral defect after septic arthritis.

    In an effort to improve detection of fastidious organisms, joint fluid aspirates of pediatric patients were inoculated into BACTEC 460 aerobic blood culture bottles, in addition to cultures on solid media. Culture records for the 1988 to 1991 period were reviewed to compare the performance of both methods for the recovery of pathogens. Overall, 216 children underwent a diagnostic joint tap, and 63 specimens grew significant organisms, including Kingella kingae in 14. While both methods were comparable for recovery of usual pathogens, with a single exception, K. kingae isolates were detected by the BACTEC system only. K. kingae appears to be a more common cause of septic arthritis in children than has been previously recognized. The BACTEC blood culture system enhances the recovery of K. kingae from joint fluid and improves bacteriologic diagnosis of pediatric septic arthritis.

    We reviewed the long-term clinical and radiological results of 63 uncemented Low Contact Stress (LCS) total knee replacements (TKRs) in 47 patients with rheumatoid arthritis. The mean age of the patients at the time of surgery was 69 years (53 to 81). At a mean follow-up of 22 years (20 to 25), 12 patients were alive (17 TKRs), 27 had died (36 TKRs), and eight (ten TKRs) were lost to follow-up. Revision was necessary in seven patients (seven TKRs, 11.1%) at a mean of 12.1 years (0 to 19) after surgery. In the surviving ten patients who had not undergone revision (15 TKRs), the mean Oxford knee score was 30.2 (16 to 41) at a mean follow-up of 19.5 years (15 to 24.7) and mean active flexion was 105° (90° to 150°). The survival rate was 88.9% at 20 years (56 of 63) and the Kaplan-Meier survival estimate, without revision, was 80.2% (95% confidence interval 37 to 100) at 25 years.

    Septic arthritis is the most rapidly destructive joint disease, but its early diagnosis remains challenging; delayed or inadequate treatment, even by expert physicians, can lead to irreversible joint destruction. Between 25% and 50% of patients develop irreversible loss of joint function, which is especially concerning in elderly patients. To understand the factors influencing the outcome of septic arthritis, the authors reviewed patients aged older than 50 years who had undergone debridement surgery for primary septic arthritis at their institution between 1998 and 2008. Ninety-two patients (92 knees) were enrolled in the study; 14 did not meet inclusion criteria and were excluded from the final analysis. Of the 78 included patients, 7 underwent arthrodesis, 22 underwent total knee arthroplasty, 19 were indicated for total knee arthroplasty for severe knee joint osteoarthritis but did not undergo surgery by the end of this study, and the remaining 30 had no or mild symptoms of osteoarthrosis and did not receive any surgical procedure. Staphylococcus aureus was the most common pathogenic agent (38%), followed by mixed bacterial infection (10%). Several factors negatively influenced the final clinical outcome, including delayed treatment, advanced macroscopic staging made during debridement surgery, performing multiple debridement surgeries, and a larger Lysholm score difference pre- and posttreatment. More antibiotics administered, longer duration of antibiotic treatment, and more pathogenic agents present were also significantly correlated with poor outcome. These findings shed new light on the management of septic arthritis. Accurate diagnoses and effective treatments are important for the clinical outcome of knee joint bacterial infection in elderly patients.

    We quantify the false-negative diagnostic rate of septic arthritis using Gram-stain microscopy of synovial fluid and compare this to values reported in the peer-reviewed literature. We propose a method of improving the diagnostic value of Gram-stain microscopy using Lithium Heparin containers that prevent synovial fluid coagulation. Retrospective study of the Manchester Royal Infirmary microbiology database of patients undergoing synovial fluid Gram-stain and culture between December 2003 and March 2012 was undertaken. The initial cohort of 1896 synovial fluid analyses for suspected septic arthritis was reduced to 143 after exclusion criteria were applied. Analysis of our Gram-stain microscopy yielded 111 false-negative results from a cohort size of 143 positive synovial fluid cultures, giving a false-negative rate of 78%. We report a false-negative rate of Gram-stain microscopy for septic arthritis of 78%. Clinicians should therefore avoid the investigation until a statistically significant data set confirms its efficacy. The investigation's value could be improved by using Lithium Heparin containers to collect homogenous synovial fluid samples. Ongoing research aims to establish how much this could reduce the false-negative rate.

    Mycoplasma salivarium is a rare agent of septic arthritis in immunocompromised patients. We report a case of septic arthritis due to Mycoplasma salivarium in a patient with B-cell chronic lymphocytic leukemia who underwent chemotherapy with rituximab and bendamustin. Therapy of arthritis due to Mycoplasma salivarium is difficult because there are almost no susceptibility data available. The present case illustrates that antimicrobial susceptibility of Mycoplasma strains is not necessarily predictable and that antibiotic therapy should therefore be guided by in vitro susceptibility testing.

    New insights into the role of tumor necrosis factor (TNF) in the pathogenesis of rheumatoid arthritis (RA) have expanded our understanding about the possible mechanisms by which anti-TNF antibody therapy reduces local synovial inflammation. Beyond local effects, anti-TNF treatment may modulate systemic antiinflammatory pathways such as the hypothalamic-pituitary-adrenal (HPA) axis. This longitudinal anti-TNF therapy study was designed to assess these effects in RA patients. RA patients were given 5 infusions of anti-TNF at weeks 0, 2, 6, 10, and 14, with followup observation until week 16. We measured serum levels of interleukin-6 (IL-6), adrenocorticotropic hormone (ACTH), 17-hydroxyprogesterone (17[OH]progesterone), cortisol, cortisone, androstenedione (ASD), dehydroepiandrosterone (DHEA), and DHEA sulfate in 19 RA patients. Upon treatment with anti-TNF, we observed a fast decrease in the levels of serum IL-6, particularly in RA patients who did not receive parallel prednisolone treatment (P = 0.043). In these RA patients who had not received prednisolone, the mean serum ACTH levels sharply increased after every injection of anti-TNF, which indicates a sensitization of the pituitary gland (not observed for the adrenal gland). During treatment, the ratio of serum cortisol to serum ACTH decreased, which also indicates a sensitization of the pituitary gland (P < 0.001), and which was paralleled by constant cortisol secretion. The adrenal androgen ASD significantly increased relative to its precursor 17(OH)progesterone (P = 0.013) and relative to cortisol (P = 0.009), which indicates a normalization of adrenal androgen production. The comparison of patients previously treated with prednisolone and those without previous prednisolone revealed marked differences in the central and adrenal level of this endocrine axis during long-term anti-TNF therapy. Long-term therapy with anti-TNF sensitizes the pituitary gland and improves adrenal androgen secretion in patients who

    Background: Preliminary studies have identified known bacterial pathogens in the knees of patients with osteoarthritis (OA) before arthroplasty. Aims: The current study was designed to determine the incidence and types of bacteria present in the synovial fluid of native knee joints from adult patients with diagnoses of septic arthritis and OA. Patients and Methods: Patients were enrolled between October 2010 and January 2013. Synovial fluid samples from the affected knee were collected and evaluated with both traditional microbial culture and polymerase chain reaction–electrospray ionization–time-of-flight mass spectrometry (molecular diagnostics [MDx]) to prospectively characterize the microbial content. Patients were grouped by diagnosis into one of two cohorts, those with clinical suspicion of septic arthritis (n = 44) and those undergoing primary arthroplasty of the knee for OA (n = 21). In all cases where discrepant culture and MDx results were obtained, we performed species-specific 16S rRNA fluorescence in situ hybridization (FISH) as a confirmatory test. Results: MDx testing identified bacteria in 50% of the suspected septic arthritis cases and 29% of the arthroplasty cases, whereas culture detected bacteria in only 16% of the former and 0% of the latter group. The overall difference in detection rates for culture and MDx was very highly significant, p-value = 2.384 × 10−7. All of the culture-positive cases were typed as Staphylococcus aureus. Two of the septic arthritis cases were polymicrobial as was one of the OA cases by MDx. FISH testing of the specimens with discordant results supported the MDx findings in 91% (19/21) of the cases, including one case where culture detected S. aureus and MDx detected Streptococcus agalactiae. Conclusions: MDx were more sensitive than culture, as confirmed by FISH. FISH only identifies bacteria that are embedded or infiltrated within the tissue and is thus not susceptible to contamination.

    Amphotericin B (AMB) was often used in intra-articular injection administration for fungal arthritis, because it could often bring a satisfactory therapeutic efficacy and a minimum systemic toxic side effect. However, because of the multiple operations and the frequent injections, the compliance of the patients was bad. Therefore, to develop a long-term sustained-released preparation of AMB for mycotic arthritis intra-articular administration is of great significance. The purpose of present study was to develop a long-term sustained-released in situ gel of a water-insoluble drug AMB for mycotic arthritis intra-articular administration. Based on the evaluations of the in vitro properties of the formulations, the formulation containing 10% (w/w) ethanol, 15% (w/w) PG, 0.75% (w/w) HA, 5% (w/w) purified soybean oil, 0.03% (w/w) α-tocopherol, 15% (w/w) water and 55% (w/w) glyceryl monooleate was selected as a suitable intra-articular injectable in situ gel drug delivery system for water-insoluble drug AMB. Furthermore, the results of the in vivo study on rabbits showed that the selected formulation was a safe and effective long-term sustained-released intra-articular injectable AMB preparation. Therefore, the presented in situ AMB gel could reduce the frequency of the administration in the AMB treatment of fungal arthritis, and then would get a good patient compliance.

    To assess the safety and efficacy of intravenous (IV) abatacept plus methotrexate (MTX) over 7 years, the longest observational period to date, in patients with established rheumatoid arthritis (RA) and an inadequate response to MTX. Patients randomised to IV abatacept (10 or 2 mg/kg) or placebo, plus MTX, during the 1-year double-blind (DB) period of a Phase 2b study could enter the long-term extension (LTE) and receive IV abatacept 10 mg/kg monthly. Safety was assessed in patients who received ≥1 dose of abatacept; efficacy was assessed in patients originally randomised to 10 mg/kg abatacept (as-observed data). A total of 219 patients entered the LTE; 114 (52.1%) completed 7 years of treatment with abatacept plus MTX. Cumulative (DB + LTE) incidence rates of serious adverse events, serious infections, malignancies, and autoimmune events were 17.6, 3.2, 1.8, and 1.2/100 patient-years, respectively. Safety was consistent between the DB (n=220) and cumulative (n=287) periods. Improvements in American College of Rheumatology responses, disease activity, and normalisation of physical function and health-related quality of life were maintained over time. Approximately 80% of patients who achieved low disease activity or normalised modified Health Assessment Questionnaire scores at Year 1, and who remained in the study, sustained these responses in each subsequent year. IV abatacept in combination with MTX demonstrated consistent safety and sustained efficacy over 7 years in MTX inadequate responders with established RA. Furthermore, some patients demonstrated a normalisation of physical function and health-related quality of life that was sustained over time.

    A retrospective study of 191 cases of septic arthritis was undertaken at Royal Darwin Hospital in the tropical north of Australia. Incidence was 9.2 per 100,000 overall and 29.1 per 100,000 in Aboriginal Australians (RR 6.6; 95% CI 5.0-8.9). Males were affected more than females (RR 1.6; 95% CI 1.2-2.1). There was no previous joint disease or medical illness in 54%. The commonest joints involved were the knee (54%) and hip (13%). Significant age associations were infected hips in those under 15 years and infected knees in those over 45 years. Seventy two percent of infections were haematogenous. Causative organisms included Staphylococcus aureus (37%), Streptococcus pyogenes (16%) and Neisseria gonorrhoeae (12%). Unusual infections included three melioidosis cases. Polyarthritis occurred in 17%, with N. gonorrhoeae (11/23) more likely to present as polyarthritis than other organisms (22/168) (OR 6.0; 95% CI 2.1-16.7). Univariate and multivariate analysis showed the hip to be at greater risk for S. aureus than other joints. Open arthrotomy was a more successful treatment procedure than arthroscopic washout or needle aspiration.

    The effectiveness of low-level laser therapy (LLLT) in the presence of an infectious process has not been well elucidated. The aim of the study was to evaluate the effects of LLLT in an experimental model of septic arthritis. Methods. Twenty-one Wistar rats were divided as follows: control group, no bacteria; placebo group, bacteria were inoculated; Treated group, bacteria were injected and treatment with LLLTwas performed. To assess nociception, a von Frey digital analgesimeter was applied. Synovial fluid was streaked to analyze bacterial growth. The standard strain of S. aureus was inoculated in the right knee. LLLT was performed with 660 nm, 2 J/cm2, over 10 days. After treatment, the knees were fixed and processed for morphological analysis by light microscopy. Results. It was found that nociception increases in the right knee. There was a lack of results for the seeding of the synovial fluid. The morphological analysis showed slight recovery areas in the articular cartilage and synovia; however, there was the maintenance of the inflammatory infiltrate. Conclusion. The parameters used were not effective in the nociception reduction, even with the slight tissue recovery due to the maintenance of inflammatory infiltrate, but produced no change in the natural history of resolution of the infectious process.

    Serum procalcitonin (PCT) is an established diagnostic marker for severe or systemic bacterial infections such as pneumonia, sepsis and septic shock. Data regarding the role of PCT in localized infections without systemic inflammatory response syndrome are scarce. The aim of this review is to assess the value of PCT measurements in localized infections such as skin and skin structure infections, diabetic foot infections, septic arthritis (SA) and osteomyelitis. It appears that serum PCT is unlikely to change the clinical practice in skin and skin structure infection. However, serum PCT could have a role in diagnosis and monitoring of diabetic foot infections in hospitalized settings. There are conflicting reports regarding the ability of serum PCT to distinguish SA from non-SA; synovial PCT may be more appropriate in these settings, including in implant-related infections. Better designed studies are needed to evaluate the usefulness of PCT with or without other biomarkers in localized infections.

    Bacterial arthritis is a rapidly progressive and highly destructive joint disease in humans, with Staphylococcus aureus and Neisseria gonorrhoeae the major causative agents, although beta-hemolytic streptococci as well often induce the disease. We demonstrate here that intravenous inoculation of CD-1 mice with the group A streptococcus (GAS) species Streptococcus pyogenes resulted in a high incidence of septic arthritis. Signs of arthritis emerged within the first few days after injection, and bacterial examinations revealed that colonization of the inoculated GAS in the arthritic joints persisted for 21 days. Induction of persistent septic arthritis was dependent on the number of microorganisms inoculated. Immunohistochemical staining of GAS with anti-GAS antibodies revealed colonization in the joints of infected mice. Cytokine levels were quantified in the joints and sera of infected mice by using an enzyme-linked immunosorbent assay. High levels of interleukin-1beta (IL-1beta) and IL-6 were detected in the joints from 3 to 20 days after infection. We noted that an increase in the amount of receptor activator of NF-kappaB ligand (RANKL), which is a key cytokine in osteoclastogenesis, was also evident in the joints of the infected mice. RANKL was not detected in sera, indicating local production of RANKL in the infected joints. Blocking of RANKL by osteoprotegerin, a decoy receptor of RANKL, prevented bone destruction in the infected joints. These results suggest that GAS can colonize in the joints and induce bacterial arthritis. Local RANKL production in the infected joints may be involved in bone destruction.

    The known risk factors for radiologic progression in rheumatoid arthritis (RA) are not optimally discriminative in patients with early disease who do not have evidence of radiologic damage. We sought to determine whether urinary C-terminal crosslinking telopeptide of type I (CTX-I) and type II (CTX-II) collagen (markers of bone and cartilage destruction, respectively) are associated with long-term radiologic progression in patients with early RA. This was a prospective study of 110 patients with early RA who were participating in the COBRA (Combinatietherapie Bij Reumatoïde Artritis) clinical trial and followup study, a randomized controlled trial comparing the efficacy of oral pulse prednisolone, methotrexate, plus sulfasalazine with sulfasalazine alone. We investigated the relationship between baseline levels of urinary CTX-I and CTX-II and the mean annual progression of joint destruction over a median of 4 years, as measured by changes in the modified Sharp score (average of 2 independent readers). In multivariate logistic regression analysis, baseline urinary CTX-I and CTX-II levels in the highest tertile were the strongest predictors of radiologic progression (Sharp score increase >2 units/year; odds ratio 7.9 and 11.2, respectively), independently of treatment group, erythrocyte sedimentation rate (ESR), Disease Activity Score in 28 joints, rheumatoid factor (RF), and baseline joint damage (Sharp score). The likelihood ratios for a positive test were 3.8 and 8.0 for CTX-I and CTX-II, respectively, which compared favorably with the likelihood ratios for the ESR (3.0), baseline joint damage (1.6), and RF (1.8). When patients were grouped according to the presence (Sharp score >/=4, n = 49) and absence (Sharp score <4, n = 61) of joint damage at baseline, CTX-I and CTX-II levels were predictive only in those without baseline joint damage (odds ratio 14.9 and 25.7, respectively). High baseline levels of urinary CTX-I and CTX-II independently predict an increased

    This study aimed to critically investigate all-cause and major-cause mortality of incident rheumatoid arthritis (RA) cases versus matched non-RA comparison (CN) subjects in a long-term prospective cohort. Baseline 1974 cohort entry demographic and serum biomarker data on 54 incident RA patients and 216 matched CN subjects were related to their mortality from 1995 through 2015. Mortality of RA patients was also analysed by 3 categories of course responses to therapy assigned by the sole community rheumatologist in 1995 (19 good, 23 fair, and 12 limited). Cox proportional hazards regression models including baseline covariates were used to determine survival from all-causes, cardiovascular disease (CVD), respiratory-related, malignancies, and other causes of death (CODs). Total deaths occurred in 38 (70.4 percent) of 54 RA and 102 (47.7 percent) of 216 CN (p=0.003). Total mortality remained greater (p=0.011) in RA versus CN subjects after adjustment for baseline demographic covariates (HR= 1.66, 95% CI 1.12-2.46). Respiratory-related CODs were also greater (p=0.047) in RA versus CN (HR= 2.69, 95% CI 1.02-7.14) subjects. The RA patients' responses to therapy in 1995 significantly (p=0.004) predicted total mortality. Baseline serum immunological and steroid biomarkers independently predicted total, CVD, and other and unknown CODs. Pre-clinical (1974) ranked biomarker z-score values (1 = lowest, 5 = highest) within matched sets of 1 RA and 4 CN study subjects independently associated with mortality from 1995 through 2015, for both total (CRP, p=0.028 and sIL-2Rα, p=0.030) and CVD (CRP, p=0.005 and sTNF-R1, p=0.003) deaths. Total mortality and respiratory-related CODs were greater in incident RA versus CN subjects. The 35 RA cases who had fair or limited course responses to rheumatologist's therapy had greater mortality than their matched CN, whereas the 19 good RA responders had equivalent survival to CN subjects.

    Scedosporium prolificans, also known as Scedosporium inflatum, is a fungus widespread in soil, sewage, and manure. This species is highly virulent and is an emerging opportunistic pathogen found in penetrating injuries in immunocompromised patients. Here we report on an immunocompetent patient with bilateral hip S. prolificans-associated osteomyelitis and septic arthritis caused by intentional penetrating trauma. The condition was refractory to initial antimicrobial suppression and surgical irrigation and debridement. Successful outcome was achieved after incorporating a bilateral two-stage total-hip-arthroplasty with Voriconazole-loaded cement and spacer. PMID:28163947

    Staphylococcus aureus is the major cause of human septic arthritis and osteomyelitis, which deserve special attention due to their rapid evolution and resistance to treatment. The progression of the disease depends on both bacterial presence in situ and uncontrolled disruptive immune response, which is responsible for chronic disease. Articular and bone infections are often the result of blood bacteremia, with the knees and hips being the most frequently infected joints showing the worst clinical outcome. We report the development of a hematogenous model of septic arthritis in murine knees, which progresses from an acute to a chronic phase, similarly to what occurs in humans. Characterization of the local and systemic inflammatory and immune responses following bacterial infection brought to light specific signatures of disease. Immunization of mice with the vaccine formulation we have recently described (4C-Staph), induced a strong antibody response and specific CD4+ effector memory T cells, and resulted in reduced bacterial load in the knee joints, a milder general inflammatory state and protection against bacterial-mediated cellular toxicity. Possible correlates of protection are finally proposed, which might contribute to the development of an effective vaccine for human use.

    Background. The standard use of vaccinations against pathogens has resulted in a decreased incidence of musculoskeletal infections caused by these previously common bacterial pathogens. Consequently, the incidence of infections caused by atypical bacteria is rising. This report presents a case of septic arthritis caused by non-type b H. influenzae in a pediatric patient. Methods. We report a case of an infant with polyarticular septic arthritis caused by H. influenzae serotype f. A literature review was conducted with the inclusion criteria of case reports and studies published between 2004 and 2013 addressing musculoskeletal H. influenzae infections. Results. An 8-month-old female presented with pain and swelling in her right ankle and left elbow. The patient was diagnosed with septic arthritis and underwent incision and drainage. Wound and blood cultures were positive for Haemophilus influenzae serotype f. In addition to treatment with IV antibiotics, the patient underwent immunocompetency studies, which were normal. Subsequent follow-up revealed eradication of the infection. Conclusions. Haemophilus influenzae non-type b may cause serious invasive infections such as sepsis or septic arthritis in children with or without predisposing factors such as immunodeficiency or asplenia. Optimal treatment includes surgical management, culture driven IV antibiotics, and an immunologic workup. PMID:26064739

    We have evaluated the efficacy and safety of tocilizumab (TCZ) re-administration in patients with active rheumatoid arthritis (RA) who had previously received TCZ treatment for about 31 months. Four patients whose RA had been well-controlled with 8 mg/kg TCZ treatment every 4 weeks and had withdrawn from the treatment were enrolled. They resumed TCZ treatment after TCZ was authorized for RA treatment in Japan. Disease activity was assessed by the Disease Activity Score 28 using erythrocyte sedimentation rate (DAS28-ESR), and synovitis in the wrists and elbows was measured by ultrasonography at baseline and during follow-up. The mean DAS28-ESR was 6.32 before the first TCZ infusion. After fewer than 20 months of initial TCZ treatment, the mean DAS28-ESR decreased to 1.87. However, after withdrawal of TCZ treatment, the disease activity could not be sufficiently controlled with conventional disease-modifying antirheumatic drugs or biologic agents. The maximum interval between TCZ treatments was approximately 34 months. Following reinstatement of the TCZ treatment, within 12 months the mean DAS28-ESR improved from 5.21 to 2.87, with the synovitis in the wrists and elbow joints also showing great improvement. These findings demonstrate that TCZ retreatment in active RA patients who had relapsed after long-term discontinuation of TCZ treatment led to an improvement in the signs and symptoms of RA and in synovitis without any severe adverse events.

    Objectives To determine how adult juvenile idiopathic arthritis (JIA) patients fulfil classification criteria for adult rheumatic diseases, evaluate their outcomes and determine clinical predictors of inactive disease, functional status and damage. Methods Patients with JIA registered on the Rheumatic Diseases Portuguese Register (Reuma.pt) older than 18 years and with more than 5 years of disease duration were included. Data regarding sociodemographic features, fulfilment of adult classification criteria, Health Assessment Questionnaire, Juvenile Arthritis Damage Index—articular (JADI-A) and Juvenile Arthritis Damage Index—extra-articular (JADI-E) damage index and disease activity were analysed. Results 426 patients were included. Most of patients with systemic JIA fulfilled criteria for Adult Still's disease. 95.6% of the patients with rheumatoid factor (RF)-positive polyarthritis and 57.1% of the patients with RF-negative polyarthritis matched criteria for rheumatoid arthritis (RA). 38.9% of the patients with extended oligoarthritis were classified as RA while 34.8% of the patients with persistent oligoarthritis were classified as spondyloarthritis. Patients with enthesitis-related arthritis fulfilled criteria for spondyloarthritis in 94.7%. Patients with psoriatic arthritis maintained this classification. Patients with inactive disease had lower disease duration, lower diagnosis delay and corticosteroids exposure. Longer disease duration was associated with higher HAQ, JADI-A and JADI-E. Higher JADI-A was also associated with biological treatment and retirement due to JIA disability and higher JADI-E with corticosteroids exposure. Younger age at disease onset was predictive of higher HAQ, JADI-A and JADI-E and decreased the chance of inactive disease. Conclusions Most of the included patients fulfilled classification criteria for adult rheumatic diseases, maintain active disease and have functional impairment. Younger age at disease onset was predictive

    Abstract Objectives. To evaluate the long-term efficacy and safety of certolizumab pegol (CZP) plus methotrexate treatment and to assess the efficacy of two CZP maintenance dosing schedules in Japanese rheumatoid arthritis (RA) patients with an inadequate response to methotrexate. Methods. J-RAPID double-blind patients were entered into an open-label extension (OLE) study. Patients withdrawn due to lack of efficacy at 16 weeks and double-blind completers without a week-24 American College of Rheumatology (ACR) 20 response received CZP 200 mg every other week (Q2W) plus methotrexate. Double-blind completers with week-24 ACR20 responses were randomized to CZP 200 mg Q2W plus methotrexate or CZP 400 mg every 4 weeks plus methotrexate. Results. The ACR20/ACR50/ACR70 response rates of double-blind completers (n = 204) were 89.7%/67.2%/36.3% at OLE entry and 95.6%/84.8%/58.3% at 52 weeks, respectively. Other clinical, functional and radiographic outcomes were sustained with long-term CZP plus methotrexate. Long-term treatment with CZP was well-tolerated with no new unexpected adverse events observed. The efficacy and safety of CZP treatment were similar between the two dosing schedules. Conclusions. Continued CZP administration with methotrexate maintained efficacy over 52 weeks and was well-tolerated for Japanese RA patients. No obvious differences in clinical efficacy and safety were observed between the two dosing schedules, giving flexibility in maintenance administration schedules. PMID:24593170

    We studied the in vivo effect of long-term doxycycline treatment combined with NSAID on human interstitial collagenases, other matrix metalloproteinases, serine proteinases, tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) and lactoferrin from saliva and serum during the course of acute reactive arthritis (ReA). Collagenase activity and serine proteases (elastase-like, cathepsin G-like and trypsin-like activities) of saliva (n = 10) and gelatinase, lactoferrin and TIMP-1 of saliva (n = 10) and serum (n = 10) samples before and after 2 months doxycycline treatment, combined with NSAID, were studied by quantitative SDS-PAGE assay, ELISA assay and by spectrophotometric assay. The cellular source and molecular forms of salivary collagenase were characterized by immunoblotting using specific antisera. We found that activities of total and endogenously active interstitial collagenase reduced significantly. The salivary collagenase was found to originate from neutrophils. No fragmentation of either pro 75-kD and active 65-kD MMP-8 was detected after 2 months doxycycline treatment. However, during 2 months doxycycline and NSAID treatment no reduction of salivary and serum gelatinase, lactoferrin and TIMP-1-levels and salivary serine protease activities were detected. The in vivo inhibition of collagenase (MMP-8) activity during long-term doxycycline therapy in human saliva containing inflammatory exudate of ReA patients may contribute to the reduced tissue destruction observed in recent clinical and animal model studies in arthritides during long-term doxycycline/tetracycline treatment.

    Corynebacterium diphtheriae is a well-known cause of localized respiratory tract infections. However, this micro-organism can also be associated with invasive infections, such as endocarditis, septic arthritis and osteomyelitis. Invasive infections are often caused by non-toxigenic strains. To set up an in vivo experimental model of C. diphtheriae infection, mice were infected intravenously with different doses (ranging from 1 x 10(7) to 5 x 10(8) bacteria per mouse) of three non-toxigenic strains, namely ISS-4749, ISS-4746 and ISS-3319. Similar mortality rates were observed with the three strains, with an LD50 ranging from 9 x 10(7) to 1.2 x 10(8). All strains were arthritogenic, although to different extents. ISS-4749 and ISS-4746 infection resulted in a maximum of 60 and 50 %, respectively, of animals with articular lesions, while in the ISS-3319-infected group only 25 % were positive. There were differences in systemic and joint cytokine production in the three experimental groups. ISS-4749- and ISS-4746-infected mice exhibited higher local levels of interleukin (IL)-6 and IL-1beta than ISS-3319-infected animals. At systemic levels, ISS-3319 was able to induce early and sustained production of interferon-gamma (IFN-gamma), but not IL-6. Conversely, infection with the other strains resulted in high IL-6, but not IFN-gamma, production. In conclusion, an experimental model of C. diphtheriae infection was set up, with development of septic arthritis. This model could be useful in studies on the pathogenicity and characterization of virulence factors other than toxin production.

    BACKGROUND: The bacterium Kingella kingae may be an under-recognized cause of septic arthritis in Canadian children because it is difficult to grow in culture and best detected using molecular methods. OBJECTIVES: To determine whether K kingae is present in culture-negative joint fluid specimens from children in eastern Ontario using polymerase chain reaction (PCR) detection methods. METHODS: K kingae PCR testing was performed using residual bacterial culture-negative joint fluid collected from 2010 to 2013 at a children’s hospital in Ottawa, Ontario. The clinical features of children with infections caused by K kingae were compared with those of children with infections caused by the ‘typical’ septic arthritis bacteria, Staphylococcus aureus and Streptococcus pyogenes. RESULTS: A total of 50 joint fluid specimens were submitted over the study period. Ten were culture-positive, eight for S aureus and two for S pyogenes. Residual joint fluid was available for 27 of the 40 culture-negative specimens and K kingae was detected using PCR in seven (25.93%) of these samples. Children with K kingae were significantly younger (median age 1.7 versus 11.3 years; P=0.01) and had lower C-reactive protein levels (median 23.8 mg/L versus 117.6. mg/L; P=0.01) than those infected with other bacteria. CONCLUSIONS: K kingae was frequently detected using PCR in culture-negative joint fluid specimens from children in eastern Ontario. K kingae PCR testing of culture-negative joint samples in children appears to be warranted. PMID:27095882

    Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease occasionally associated with severe extra-articular manifestations, mostly in cases of longstanding highly active disease. We report the case of a 56 year-old woman diagnosed with active RA at the age of 40. After 5 years of high activity, her arthritis subsides spontaneously during pregnancy despite the lack of treatment with disease-modifying anti-rheumatic drugs. She remains without articular symptoms for 7 years, and then she develops a Felty's syndrome requiring steroid treatment and splenectomy. Following steroid withdrawal she develops pericarditis with massive serohematic pericardial effusion, still in absence of articular activity, and responds to immunosuppressive therapy and colchicine. We emphasize the unusual spontaneous and sustained joint remission without specific treatment, and the development of severe extra-articular manifestations of RA in absence of concomitant articular activity, as well as the importance of controlling inflammation.

    In juvenile idiopathic arthritis (JIA), temporomandibular joint involvement is a frequent complication leading to deficient mandibular growth. Occurring unilaterally this will give rise to mandibular and maxillary asymmetry that will affect the soft tissue and the muscles and result in complex dentofacial anomaly. In the case of severe dentofacial malformation, orthognathic surgery is the only treatment option. Vertical osseodistraction of the mandibular ramus has been suggested as a means of rectifying the mandibular growth deviation and soft-tissue problems. Whether such treatment introduces dysfunctional side effects of the temporomandibular joint and muscles has been debated and concern has been raised that treatment impairs the patient's mouth opening capacity and mandibular movement. The present study prospectively evaluated 23 patients with JIA and mandibular asymmetry caused by unilateral temporomandibular joint arthritis. The authors found a clinical effect on the asymmetry with only minor subjective complaints and limited objective changes in functional parameters.

    Synovial fluid specimens obtained from patients with arthritis were plated onto solid media (conventional cultures) or inoculated into an Isolator 1.5 microbial tube (Isolator cultures), and the yield and time to detection of organisms were compared. Overall, 144 specimens obtained from 137 patients were processed, and 31 (21.5%) cultures obtained from 29 patients were positive by at least one method. Staphylococcus aureus was isolated from 12 patients, Streptococcus pneumoniae and Kingella kingae were isolated from 4 patients each, group G streptococci were isolated from 3 patients, Staphylococcus epidermidis and members of the family Enterobacteriaceae were isolated from 2 patients each, and Streptococcus mitis and Peptostreptococcus prevotii were isolated from 1 patient each. Overall, the causative organism was detected in 31 of 31 (100.0%) Isolator cultures and 24 of 31 (77.4%) conventional cultures (P < 0.02). Twenty-nine of 31 (93.5%) positive Isolator cultures and 20 of 24 (83.3%) conventional cultures were positive by the second day of incubation. Among the 24 cultures positive by both methods, higher numbers of CFU per milliliter were detected with the Isolator system in 13 cultures and with conventional cultures in 2 cultures (P < 0.002). Inoculation of synovial fluid into an Isolator 1.5 microbial tube improves the recovery of organisms causing septic arthritis.

    To determine common methods for intra-articular injections and variables associated with the risk of septic arthritis following intra-articular injection in the horse. Cross-sectional survey. Equine veterinarians. A link to an online survey was distributed to equine practitioners in 2014. Responses for descriptive data were tabulated. Data on infection rates obtained from medical records were analyzed. Variables associated with the risk of septic arthritis were determined using χ(2) or Fisher's exact tests and logistic regression. Common current methods for intra-articular injections were determined from 241 surveys. Sixty-four of 241 surveys (26.6%) contained data with numbers of joints injected and number of infections obtained from review of medical records. Eight different injection methods were used by more than 2/3 of responding veterinarians. A total of 67 out of 319,760 injected joints reported became septic following injection, giving an incidence of 2.10 septic joints per 10,000 intra-articular injections. Based on multivariate analysis, infection rates were significantly lower when veterinarians prepared their own injection sites (OR=0.10) and had <20 years of practice experience (OR=0.025), whereas infection rates were significantly higher when hair was removed at the injection site (OR=19.70). There is a low incidence of septic arthritis following intra-articular injection and a large number of injection methods reported by responding veterinarians. The low reported incidence of infection may be related to the large number of practitioners frequently using common methods. © Copyright 2016 by The American College of Veterinary Surgeons.

  15. Septic arthritis and osteomyelitis in a 10-year-old boy, caused by Fusobacterium nucleatum, diagnosed with PCR/16S ribosomal bacterial DNA amplification

    A 10-year-old boy presented with an atypical non-febrile septic arthritis/osteomyelitis. He was unresponsive to routine antibiotic treatment with flucloxacillin/gentamicin as the pain and fluid collection increased. Synovial fluid cultures are negative and gram stain remained negative. Only after PCR/16S ribosomal bacterial DNA amplification a Fusobacterium nucleatum could be detected, and antibiotic therapy switched to clindamycin with rapid response. Septic osteomyelitis and arthritis are relatively rare but important infections in children needing prompt treatment, and should be considered when a child complaints about joint or bone pain without prior recent trauma. Skin bacteria are the most prevalent causative organisms, whereas Fusobacteria or other anaerobic, Gram-negative microorganisms are very seldom encountered. If cultures remain negative and the patients responds insufficiently to empiric treatment, PCR/16S ribosomal bacterial DNA amplification can be useful to detect the causative microorganisms.

    Despite advancement in the field of antibiotics septic arthritis remains a serious concern till date. Staphylococcus aureus is the most common bacterium that causes septic arthritis. Severity of this disease is directly correlated with chronic inflammation induced by proinflammatory cytokines like TNF-α, interleukin (IL)-1β, IL-6, and induction of matrix metalloproteinases (MMPs) including MMP-2. The objective of our study was to evaluate the role of MMP-2 and tumor necrosis factor receptor 1 (TNFR1) in the pathogenesis of S. aureus infection-induced septic arthritis. Mice were infected with live S. aureus (5 × 10(6) cells/ml) followed by administration of MMP-2 inhibitor and TNFR1 antibody. Arthritis index showed highest reduction in severity of arthritis in mice treated with both MMP-2 inhibitor and TNFR1 antibody after infection. Combined neutralization of MMP-2 and TNFR1 led to marked diminution in bacterial count in the combined group. Lowest levels of pro inflammatory cytokines like TNF-α, IL-1β, IL-6, and IFN-γ were observed in both serum and synovial tissues indicating maximum protection in S. aureus arthritis during combination treatment. Increment in the level of IL-10 in the combination group could be positively correlated with the recovery of arthritis. Similarly, expressions of COX-2 and iNOS, markers of acute inflammation were also significantly reduced in the combination group due to resolution of inflammation. Levels of O2(.-) and NO also showed a significant fall in case of the group treated with MMP-2 inhibitor and TNFR1 antibody both. Neutralization of both MMP-2 and TNFR1 caused rapid decline in recruitment of neutrophil and macrophages in the synovial tissues as evident from reduced MPO and MCP-1 levels, respectively, compared to other groups. Overall, it can be suggested that administration of MMP-2 inhibitor and TNFR1 antibody in combination is protective against the severity of inflammation and cartilage destruction associated with S

    Twenty patients with intractable rheumatoid arthritis were randomized to receive 750 or 2,000 rads of lymphoid irradiation (LI) in a double-blind comparative study, and were followed for a maximum of 48 months (mean 40 months) after treatment. During followup, sustained immunomodulation (including lymphopenia, particularly of the T helper cell subset; reduced ratio of helper cells to suppressor cells; and impaired in vitro lymphocyte proliferation in response to phytohemagglutinin and pokeweed mitogen) was observed. Significant improvements in early morning stiffness, Ritchie articular index, pain score, grip strength, and 15-meter walk time were observed in both treatment groups, but these were not sustained through the followup period. Progressive joint damage was observed radiologically in both groups during followup. Thus, LI induced sustained immunosuppression, but resulted in only short-lived clinical improvement and was associated with progressive joint erosion in these patients.

    To examine the long-term outcomes (minimum of 4,5 years) of endoscopic endonasal odontoidectomy (EEO) with preservation of anterior C1 ring to treat irreducible ventral bulbo-medullary compressions in rheumatoid arthritis (RA) and to illustrate a novel technique of anterior pure endoscopic craniovertebral junction (CVJ) reconstruction and fusion. In fact, long-term clinical studies are still lacking to elucidate the effective role of EEO and whether it can obviate the need for posterior fixation. From November 2008 to January 2012, clinical and radiological data of 7 patients presenting with RA and associated irreducible bulbo-medullary compression treated with EEO were retrospectively analyzed. In all patients decompression was achieved by EEO with anterior C1 arch preservation. In the last two patients, after EEO, we used the spared anterior C1 arch for reconstruction of anterior column of CVJ by positioning, under pure endoscopic guidance, autologous bone and two tricortical screws between the anterior arch of C1 and the residual odontoid. All patients were examined clinically with Ranawat classification and radiographically with CT scan, MRI and dynamic x-ray immediately after surgery and during follow-up. Adequate bulbo-medullary decompression with anterior C1 arch preservation was obtained in all cases. At follow up (average 66,2 months; range 91-54 months) all patients experienced an improvement at least of one Ranawat classification level and presented no clinical and/or radiological signs of instability. EEO with anterior C1 arch sparing provides satisfying long term results for irreducible ventral CVJ lesions in RA. The preservation of anterior C1 arch and, when possible, the reconstruction of anterior CVJ can prevent the need for posterior fusion. Copyright © 2017 Elsevier Inc. All rights reserved.

    The objective of this study was to evaluate the long-term effects of anti-TNF-alpha treatment on temporomandibular joints (TMJs), oral mucosa, and salivary flow in RA. Seventeen patients received infusions of TNF-alpha blocking agents after 0, 2, and 6 weeks, and then every 8 weeks until week 54 (follow-up). Clinical dysfunction index (Di) for the TMJ system, salivary flow, disease activity score (DAS28), and other medical assessments were calculated at weeks 0 and 54. Median Di was 5.0 (range 0-21) at baseline and 1.0 (range 0-6) (P = .001) at follow-up. Mean salivary flow was 3.2 mL/15 minutes at baseline and 4.6 at follow-up (P = .055). Two (11.7%) of the patients developed oral candidiasis during the period of treatment. The median DAS28 was 6.2 (range, 4.7-7.7) at baseline and 4.1 (range, 1.6-6.8) at follow-up (P = .001). We conclude that anti-TNF-alpha blocking treatments have beneficial effects on oral as well as general manifestations of RA.

    The aim of this analysis is to examine the longitudinal impact of symptoms of depression/anxiety on treatment response, long-term disease activity and physical disability in RA. Secondary analysis of clinical trial data was performed. Data were collected at baseline and at 6-monthly intervals for 2 years. The EuroQoL (EQ-5D(TM)) indicated depression/anxiety symptom severity. Our primary outcomes of interest were (i) DAS-28 and (ii) physical disability measured via the HAQ. Secondary outcomes were: tender and swollen joint counts, patient global assessment, ESR and odds of reaching clinical remission. Multilevel models were used to assess the impact of baseline and persistent depression/anxiety on outcomes over 2 years. Data from 379 patients were included. After adjusting for covariates, baseline depression/anxiety symptoms were associated with increased DAS-28 outcomes and increased tender joint counts. Persistent depression/anxiety symptoms were associated with increased DAS-28 scores, HAQ scores, tender joint counts and patient global assessment of disease activity, and reduced odds of reaching clinical remission. Patients with symptoms of depression/anxiety at baseline also showed a 50% reduction in prednisolone treatment effect, in comparison with patients with no symptoms of depression/anxiety at baseline. Baseline and persistent symptoms of depression/anxiety are associated with poorer health outcomes over time, as well as reduced treatment response. Mental health should be routinely measured both in clinical practice and in research, and managed alongside rheumatological disease to optimize health outcomes. Further research is required to examine whether treatment of mental disorders can improve rheumatological outcomes. © The Author 2015.

    To compare the survival of subcutaneous anti-tumor necrosis factor (TNF) drugs used between 2008 and 2012 prescribed in accordance with clinical practice. Retrospective, observational study of the patients in our center diagnosed with rheumatoid arthritis (RA). We included patients who had received a subcutaneous anti-TNF agent for at least 6 months. The data were analyzed using the SPSS V17.0 statistical package. Forty-nine RA patients started subcutaneous biological treatment with an anti-TNF agent (32 with etanercept and 17 with adalimumab). The mean age was 45.94 years (75.5% female). The mean disease duration prior to starting anti-TNF administration was 2.67 years. The mean age at the start of treatment was 51.84 years, and the average Disease Activity Score 28 was 4.93. The median survival of the anti-TNF treatment was 8.40 years; the survival of etanercept was the longer of the two. The main reason for discontinuation was secondary failure (90.9%). In routine clinical practice, the survival of subcutaneous anti-TNF treatment was extensive and was independent of whether or not the patients received concomitant immunosuppressive therapy.

    Objectives To examine the association between disease activity in early rheumatoid arthritis (RA), functional limitation and long-term orthopaedic episodes. Methods Health Assessment Questionnaire (HAQ) disability scores were collected from two longitudinal early RA inception cohorts in routine care; Early Rheumatoid Arthritis Study and Early Rheumatoid Arthritis Network from 1986 to 2012. The incidence of major and intermediate orthopaedic surgical episodes over 25 years was collected from national data sets. Disease activity was categorised by mean disease activity score (DAS28) annually between years 1 and 5; remission (RDAS≤2.6), low (LDAS>2.6–3.2), low-moderate (LMDAS≥3.2–4.19), high-moderate (HMDAS 4.2–5.1) and high (HDAS>5.1). Results Data from 2045 patients were analysed. Patients in RDAS showed no HAQ progression over 5 years, whereas there was a significant relationship between rising DAS28 category and HAQ at 1 year, and the rate of HAQ progression between years 1 and 5. During 27 986 person-years follow-up, 392 intermediate and 591 major surgeries were observed. Compared with the RDAS category, there was a significantly increased cumulative incidence of intermediate surgery in HDAS (OR 2.59 CI 1.49 to 4.52) and HMDAS (OR 1.8 CI 1.05 to 3.11) categories, and for major surgery in HDAS (OR 2.48 CI 1.5 to 4.11), HMDAS (OR 2.16 CI 1.32 to 3.52) and LMDAS (OR 2.07 CI 1.28 to 3.33) categories. There was no significant difference in HAQ progression or orthopaedic episodes between RDAS and LDAS categories. Conclusions There is an association between disease activity and both poor function and long-term orthopaedic episodes. This illustrates the far from benign consequences of persistent moderate disease activity, and supports European League Against Rheumatism treat to target recommendations to secure low disease activity or remission in all patients.

    Objective Aims of the study were to investigate health-related quality of life (HRQOL) in adult patients with former diagnosis of Juvenile Idiopathic Arthritis (JIA), to compare their HRQOL with the general population and to identify factors related to a poor outcome. Methods In 2012, a cross-sectional survey was performed by mailing a questionnaire to a large cohort of former and current patients of the German Centre for Rheumatology in Children and Adolescents. Only adult patients (≥18 years) with a diagnosis compatible with JIA were included (n = 2592; response 66%). The questionnaire included information about HRQOL (EQ5D), disease-related questions and socio-demographics. Prevalence and 95% confidence intervals (CI) of problems with mobility, self-care, usual activities, pain and anxiety/depression were standardized to the German general population. Factors associated with low HRQOL in JIA patients were identified using logistic regression models. Results Sixty-two percent of the study population was female; age range was 18–73 years. In all dimensions, JIA patients reported statistically significantly more problems than the general population with largest differences in the pain dimension (JIA patients 56%; 95%CI 55–58%; general population 28%; 26–29%) and the anxiety/depression dimension (28%; 27–29% vs. 4%; 4–5%). Lower HRQOL in JIA patients was associated with female sex, older age, lower level of education, still being under rheumatic treatment and disability. Conclusions HRQOL in adult JIA patients is considerably lower than in the general population. As this cohort includes historic patients the new therapeutic schemes available today are expected to improve HRQOL in future. PMID:27115139

    In an epidemic of septic arthritis due to Serratia marcescens, the intra-articular injection of contaminated methylprednisolone may have played a key role. The epidemic strain was found in used multiple-dose vials of methylprednisolone and in a canister of cotton balls soaked in benzalkonium chloride. The cotton balls had been used for antisepsis and disinfection. Growth characteristics of the epidemic strain of S. marcescens were compared with those of control strains of S. marcescens which had been obtained from unrelated nosocomial outbreaks. The epidemic strain was able to survive in 1:100 dilutions of benzalkonium chloride and was able to grow to greater than 10(5) CFU/ml in multiple-dose vials of methylprednisoline; control strains could not be recovered after 24 h in the same solutions. The preservative in methylprednisolone is gamma-myristyl picolinium chloride, a compound chemically related to benzalkonium chloride. We speculate that the epidemic strain of S. marcescens, which was resistant to benzalkonium chloride, had cross-resistance to gamma-myristyl picolinium chloride. If the cotton balls were used to disinfect the tops of the multiple-dose vials of methylprednisolone, small numbers of organisms subsequently introduced into the solution could have grown to high concentrations.

    Among the causes of limping gait in children, septic arthritis (SA) and transient synovitis (TS) are the 2 most likely etiologies. The aim of this study was to determine the medical histories, physical examinations, and other studies to use to create a clinical guideline for differential diagnosis between SA and TS in children in the emergency department (ED). The pediatric orthopedic emergency committee of our institution addressed the issue of developing a guideline for differential diagnosis. Two rounds of the modified Delphi survey were conducted, and a face-to-face committee meeting was held after each survey round. Delphi survey panelists included 10 pediatric orthopedic surgeons and 8 emergency physicians including 3 pediatric emergency physicians. Response rates were 100% in each round. The panelists used a 6-point Likert scale to rate the clinical diagnostic guideline contents as having high (5 or 6), moderate (3 or 4), or low importance (1 or 2). Twenty-eight questionnaire items were included in the first round; and 18 items, in the second round. Factors for concern were selected, and a flowchart of the diagnostic guideline development process was based on the results of the survey. A diagnostic guideline for evaluating SA and TS in children in the ED was achieved using combined empirical evidence together with expert opinion, potentially resulting in a diagnostic strategy to be incorporated into existing guidelines or used on its own.

    2011-01-01

    Introduction The aim of this study was to investigate whether serum biomarker levels of C2C, C1,2C, CS846, and CPII can predict the long-term course of disease activity and radiographic progression early in the disease course of rheumatoid arthritis (RA). Methods In patients in the CAMERA trial, levels of biomarkers were evaluated at baseline and after 1 year of treatment. Relations of (changes in) biomarker values with the mean yearly radiographic progression rate and mean disease activity over a 5-year period were evaluated by using regression analysis. The added predictive value of biomarkers over established predictors for long-term outcome was analyzed by multiple linear regression analysis. Results Of 133 patients, serum samples were available at baseline and after 1 year of treatment. In the regression analysis C1,2C at baseline, the change in C2C, C1,2C, and the sum of the standardized changes in C2C + C1,2C scores were statistically significantly associated with the mean yearly radiographic progression rate; the change in CPII was associated with the mean disease activity over 5 years of treatment. In the multiple linear regression analysis, only the change in C1,2C was of added predictive value (P = 0.004) for radiographic progression. Explained variances of models for radiographic progression and disease activity were low (0.28 and 0.34, respectively), and the biomarkers only marginally improved the explained variance. Conclusions The change in C1,2C in the first year after onset of RA has a small added predictive value for disease severity over a 5-year period, but the predictive value of this biomarker combined with current predictive factors is too small to be of use for individual patients.

The change in C1,2C in the first year after onset of RA has a small added predictive value for disease severity over a 5-year period, but the predictive value of this biomarker combined with current predictive factors is too small to be of use for individual patients.

    To assess if there is a correlation between the degree of response to treatment with methotrexate (MTX) and long-term mortality in a cohort of patients with rheumatoid arthritis (RA) established in Germany in the early eighties. RA patients who had started MTX treatment between 1980 and 1987 were included. One year after baseline, the treatment response was evaluated. Responders were defined as patients with at least 20% decline in the swollen joint count (out of 32 joints) and the ESR with a prednisone dosage <5 mg/day. Thereafter, assessments were performed at 10, 18, and 30 years after baseline. Standardised mortality ratios (SMR) were calculated, Cox regression and logistic regression were performed. The cohort comprised 271 patients. In 2015, about 30 years after the initiation of MTX therapy, 185 patients (68%) were deceased, 52 (19%) lost to follow-up and 34 alive. The response after the first year of MTX treatment was the strongest predictor of survival with a hazard ratio of 0.44 (95% confidence interval [CI]: 0.30-0.65). However, even responders still had an SMR of 1.37 (95% CI 1.31-1.65), but this was much worse for non-responders who had an SMR of 4.22 (95% CI 3.13-5.56). Using Cox regression analysis no difference was detected between responders with more than 50% improvement (38% of all patients) and those with 20-50% improvement (28%). The predictive value of a response to one year of MTX therapy for long-term mortality of RA patients is independent of the degree of response.

    We have previously described a murine model of hematogenously induced Staphylococcus aureus sepsis and arthritis. In this model, large numbers of granulocytes can be observed both in the circulation and locally in the inflamed synovium within 24 h after bacterial inoculation. To assess the role of neutrophils in this severe infection, mice were given granulocyte-depleting monoclonal antibody RB6-8C5 before being inoculated with S. aureus. All the control mice survived their intravenous injection with 3 x 10(7) CFU of S. aureus, whereas all the mice given RB6-8C5 antibody died of sepsis within 2 to 3 days. Even when the inoculum size was reduced sixfold (i.e., 6 x 10(6) CFU/mouse), 50% of the RB6-8C5-treated animals died within 6 days. The RB6-8C5-treated mice had a significantly higher burden of bacteria in their blood and kidneys 24 and 48 h after bacterial inoculation. In addition, when a suboptimal dose of bacteria was administered, the neutrophil-depleted animals displayed a higher frequency of arthritis than did the controls. The granulocyte-depleted animals exhibited increased levels of the proinflammatory cytokines tumor necrosis factor alpha, interleukin-6, and gamma interferon, reflecting the severity of their disease. This is the first direct demonstration of neutrophils playing a crucial protective role in the early phase of S. aureus infection. PMID:9199413

    The broad-range PCR has been successfully developed to search for fastidious, slow-growing or uncultured bacteria, and is mostly used when an empirical antibiotic treatment has already been initiated. The technique generally involves standard PCR targeting the gene coding for 16S ribosomal RNA, and includes a post-PCR visualisation step on agarose gel which is a potential source of cross-over contamination. In addition, interpretation of the presence of amplified products on gels can be difficult. We then developed a new SYBR Green-based, universal real-time PCR assay targeting the gene coding for 16S ribosomal RNA, coupled with sequencing of amplified products. The real-time PCR assay was evaluated on 94 articular fluid samples collected from children hospitalised for suspicion of septic arthritis, as compared to the results obtained with bacterial cultures and conventional broad-range PCR. DNA extraction was performed with the automated MagNa Pure system. We could detect DNA from various bacterial pathogens including fastidious bacteria (Kingella kingae, Streptococcus pneumoniae, Streptococcus pyogenes, Salmonella spp, Staphylococcus aureus) from 23% of cases of septic arthritis giving negative culture results. The real-time technique was easier to interpret and allowed to detect four more cases than conventional PCR. PCR based molecular techniques appear to be essential to perform in case of suspicion of septic arthritis, provided the increase of the diagnosed bacterial etiologies. Real-time PCR technique is a sensitive and reliable technique, which can replace conventional PCR for clinical specimens with negative bacterial culture.

    Isolation of bacteria from synovial fluid (SF) is the gold standard for diagnosis of septic arthritis (SA). Contamination results in misdiagnosis and mismanagement. This study identifies clinical characteristics, microbiology, and outcomes of patients with contaminated SF and compares them with patients with true SA. We conducted a retrospective study including all patients aged 18 and older admitted to a single, tertiary-care hospital between 1998 and 2015 with suspected SA and positive SF cultures. Contamination cases were determined by infectious disease specialists involved in the patients' care and a clinical course inconsistent with SA. 398 patients with true SA and 22 with contaminated SF were identified. The SA group was younger (60.9 vs. 75.6 years; p < 0.01), had higher peripheral polymorphonuclear lymphocytes (78.0 vs. 69.4%; p < 0.01) and SF white blood cell count (91.7 vs. 25.6K/mL; p = 0.02), and longer mean length of stay (10.9 vs. 6.7 days; p = 0.02). The average time to positive culture was longer in the contaminated group (3.62 vs. 1.4 days; p < 0.01). The SA group was less likely to receive a new rheumatologic diagnosis within 1 year (3.0 vs. 36.4%; p < 0.01). This is the first study of its kind looking at clinical features and outcomes of patients with contaminated SF. These patients present with less severe disease, have better outcomes, and receive new rheumatologic diagnoses in more than a third of cases within 1 year. We recommend a conservative approach for patients with suspected contaminated SF, mild symptoms, and no bacterial growth within the first 48 h.

    The incidence and severity of methicillin resistant Staphylococcus aureus (MRSA) infections are increasing and cause high mortality and morbidity. We describe the first pediatric case in Scandinavia with Panton-Valentine leucocidin (PVL) positive MRSA septicemia who developed bilateral pneumonia, arthritis of the knee, and osteomyelitis of the tibia. Radiological investigation and interpretation directed the treatment, especially the surgical debridement, and combined with clinical and biochemical findings lead to close interdisciplinary treatment with frequent surgical interventions and antimicrobial combination therapy. The outcome was a healthy patient without sequelae, a favorable course unlike those previously described in the literature. This case underlines the necessity of a close interdisciplinary cooperation in children with severe MRSA infection encompassing pneumonia, septic arthritis, and osteomyelitis, using different imaging modalities to guide the surgical and antibiotic treatment.

    Objective The aim of this study was to assess long-term golimumab therapy in patients with rheumatoid arthritis (RA) who discontinued previous tumour necrosis factor alpha (TNFα) inhibitor(s) for any reason. Methods Results through week 24 of this multicentre, randomised, double-blind, placebo-controlled study of active RA (≥4 tender, ≥4 swollen joints) were previously reported. Patients received placebo (Group 1), 50 mg golimumab (Group 2) or 100 mg golimumab (Group 3) subcutaneous injections every 4 weeks. Patients from Groups 1 and 2 with <20% improvement in tender/swollen joints at week 16 early escaped to golimumab 50 mg and 100 mg, respectively. At week 24, Group 1 patients crossed over to golimumab 50 mg, Group 2 continued golimumab 50/100 mg per escape status and Group 3 maintained dosing. Data through week 160 are reported. Results 459 of the 461 randomised patients were treated; 236/459 (51%) continued treatment through week 160. From week 24 to week 100, ACR20 (≥20% improvement in American College of Rheumatology criteria) response and ≥0.25 unit HAQ (Health Assessment Questionnaire) improvement were sustained in 70–73% and 75–81% of responding patients, respectively. Overall at week 160, 63%, 67% and 57% of patients achieved ACR20 response and 59%, 65% and 64% had HAQ improvement ≥0.25 unit in Groups 1, 2 and 3, respectively. Adjusted for follow-up duration, adverse event incidences (95% CI) per 100 patient-years among patients treated with golimumab 50 mg and 100 mg were 4.70 (2.63 to 7.75) and 8.07 (6.02 to 10.58) for serious infection, 0.95 (0.20 to 2.77) and 2.04 (1.09 to 3.49) for malignancy and 0.00 (0.00 to 0.94) and 0.62 (0.17 to 1.59) for death, respectively. Conclusion In patients with active RA who discontinued previous TNF-antagonist treatment, golimumab 50 and 100 mg injections every 4 weeks yielded sustained improvements in signs/symptoms and physical function in ∼57–67% of patients who continued treatment.

    Objectives Evaluation of long-term safety of rituximab in rheumatoid arthritis (RA). Methods Pooled observed case analysis of data from patients with moderate-to-severe, active RA treated with rituximab in a global clinical trial programme. Results As of September 2010, 3194 patients had received up to 17 rituximab courses over 9.5 years (11 962 patient-years). Of these, 627 had >5 years’ follow-up (4418 patient-years). A pooled placebo population (n=818) (placebo+methotrexate (MTX)) was also analysed. Serious adverse event and infection rates generally remained stable over time and multiple courses. The overall serious infection event (SIE) rate was 3.94/100 patient-years (3.26/100 patient-years in patients observed for >5 years) and was comparable with placebo+MTX (3.79/100 patient-years). Serious opportunistic infections were rare. Overall, 22.4% (n=717) of rituximab-treated patients developed low immunoglobulin (Ig)M and 3.5% (n=112) low IgG levels for ≥4 months after ≥1 course. SIE rates were similar before and during/after development of low Ig levels; however, in patients with low IgG, rates were higher than in patients who never developed low IgG. Rates of myocardial infarction and stroke were consistent with rates in the general RA population. No increased risk of malignancy over time was observed. Conclusions This analysis demonstrates that rituximab remains generally well tolerated over time and multiple courses, with a safety profile consistent with published data and clinical trial experience. Overall, the findings indicate that there was no evidence of an increased safety risk or increased reporting rates of any types of adverse events with prolonged exposure to rituximab during the 9.5 years of observation.

    Land-based gas turbines are significantly different from automotive gas turbines in that they are designed to operate for 50,000 h or greater (compared to 5,000--10,000 h). The primary goal of this research is to determine the long-term survivability of ceramic materials for industrial gas turbine applications. Research activities in this program focus on the evaluation of the static tensile creep and stress rupture (SR) behavior of three commercially available structural ceramics which have been identified by the gas turbine manufacturers as leading candidates for use in industrial gas turbines. For each material investigated, a minimum of three temperatures and four stresses will be used to establish the stress and temperature sensitivities of the creep and SR behavior. Because existing data for many candidate structural ceramics are limited to testing times less than 2,000 h, this program will focus on extending these data to times on the order of 10,000 h, which represents the lower limit of operating time anticipated for ceramic blades and vanes in gas turbine engines. A secondary goal of the program will be to investigate the possibility of enhancing life prediction estimates by combining interrupted tensile SR tests and tensile dynamic fatigue tests in which tensile strength is measured as a function of stressing rate. The third goal of this program will be to investigate the effects of water vapor upon the SR behavior of the three structural ceramics chosen for the static tensile studies by measuring the flexural strength as a function of stressing rate at three temperatures.

    Foodborne infections with Campylobacter, E. coli O157:H7, Listeria monocytogenes, Salmonella, Shigella, Toxoplasma gondii, and other pathogens can result in long-term sequelae to numerous organ systems. These include irritable bowel syndrome, inflammatory bowel disease, reactive arthritis, hemolytic uremic syndrome, chronic kidney disease, Guillain-Barré Syndrome, neurological disorders from acquired and congenital listeriosis and toxoplasmosis, and cognitive and developmental deficits due to diarrheal malnutrition or severe acute illness. A full understanding of the long-term sequelae of foodborne infection is important both for individual patient management by clinicians, as well as to inform food safety and public health decision making.

    To review outcome measures and treatment costs in children with juvenile idiopathic arthritis (JIA) and low bone mineral density (BMD) and/or fragility fractures. To review evidence for effectiveness and safety of bisphosphonates and calcium and/or vitamin D in these children. To assess long-term bone health in adults with JIA. Major databases were searched up to July 2005 for effectiveness studies and up to January 2005 for costs. A structured search strategy was conducted. For the evaluation of long-term bone health, outcome data were derived from two cohorts of adult patients with JIA. As there were few published cost data, an ongoing UK longitudinal study (CAPS) provided background data on the cost of managing JIA. Sixteen studies (78 children with JIA) were included. At baseline, the children had BMD below the expected values for age- and sex-matched children; treatment with bisphosphonates increased BMD with mean percentage increases in spine BMD varying from 4.5 to 19.1%. None of the studies with control groups compared results between the intervention and control groups, they only compared each group with its own baseline. Overall, studies were heterogeneous in design, of variable quality and with no consistency in methods of assessing and reporting outcomes. Hence, data could not be combined or an effect size calculated. A further 43 papers were included in the safety review; side-effects were generally transient. Two studies assessed treatment with calcium and/or vitamin D; BMD was increased from 0.75 to 0.830 g/cm2 after 6 months and BMD Z-score from -2.8 to -2.3 after 6 months and -2.4 after 1 year. There are relatively few long-term studies on the occurrence of low BMD and fragility fractures in children with JIA, with most studies only following children for 1 or 2 years. However, the long- and short-term data indicate that children with JIA have a lower BMD and more fractures than children without JIA. There are very few data on long-term bone health

    Objectives To examine long-term visit-to-visit blood pressure (BP) variability in rheumatoid arthritis (RA) vs non-RA subjects and to assess its impact on cardiovascular events and mortality in RA. Methods Clinic BP measures were collected in a population-based incident cohort of RA patients (1987 ACR criteria met between 1/1/1995 and 1/1/2008) and non-RA subjects. BP variability was defined as within-subject standard deviation (SD) in systolic and diastolic BP. Results Study included 442 RA patients (mean age 55.5 years, 70% females) and 424 non-RA subjects (mean age 55.7 years, 69% females). RA patients had higher visit-to-visit variability in systolic BP (13.8±4.7 mm Hg), than non-RA subjects (13.0±5.2 mm Hg, p=0.004). Systolic BP variability declined after the index date in RA (p<0.001), but not in the non-RA cohort (p=0.73), adjusting for age, sex and calendar year of RA. During the mean follow-up of 7.1 years, 33 cardiovascular events and 57 deaths occurred in RA cohort. Visit-to-visit systolic BP variability was associated with increased risk of cardiovascular events (hazard ratio [HR] per 1 mm Hg increase in BP variability 1.12, 95% confidence interval [CI] 1.01-1.25); diastolic BP variability was associated with all-cause mortality in RA (HR 1.14, 95%CI 1.03-1.27), adjusting for systolic and diastolic BP, body mass index, smoking, diabetes, dyslipidemia, use of antihypertensives. Conclusion Patients with RA had higher visit-to-visit systolic BP variability vs non-RA subjects. There was a significant decline in systolic BP variability after RA incidence. Higher visit-to-visit BP variability was associated with adverse cardiovascular outcomes and all-cause mortality in RA. PMID:24986852

    To investigate if patients with early RA with persistent moderate disease activity during the first year after diagnosis have a worse 3-5 year outcome than those who achieve sustained clinical remission within the first year, in a daily life setting. The ESPOIR cohort included patients with early arthritis of <6 months' duration. Treatment was the standard of care. We had 5-year follow-up data for 573 patients. This study compared patients who had persistent moderate disease activity (Disease Activity Score in 28 joints (DAS28)>3.2 and ≤5.1) at both the 6- and 12-month visits, with those who were in sustained DAS28 remission. The primary outcome was radiographic progression at the 36-month visit. Secondary endpoints were clinical remission (DAS28 score, Simplified Disease Activity Index, ACR/EULAR criteria), Health Assessment Questionnaire-Disability Index (HAQ-DI) and number of missed workdays at months 36 and 60. A Fisher exact test was used to compare categorical variables, and the Kruskal-Wallis test for quantitative variables. Logistic regression analysis was used to determine predictors of outcome. Patients were aged 48.1±12.5 years and their duration of symptoms was 103.2±52.1 days. Mean baseline DAS28 was 5.1±1.3. Persistent moderate disease activity (107 patients) rather than sustained remission (155 patients) during the first year was associated with increased radiographic disease progression at 3 years (OR=1.99 (95% CI 1.01 to 3.79)), increased HAQ-DI at 3 and 5 years (5.23 (2.81 to 9.73) and 4.10 (2.16 to 7.80), respectively), a 7-11 times smaller chance of achieving clinical remission and a five times greater number of missed workdays. Patients with early RA with persistent moderate disease activity during the first year had a worse outcome than patients who achieved sustained clinical remission. Persistent moderate disease activity affects long-term structure, remission rate and functional and work disability. Such patients may

    Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We assessed tofacitinib efficacy and safety in the Latin American (LA) subpopulation of global Phase 3 and long-term extension (LTE) studies. Data from LA patients with RA and inadequate response to disease-modifying antirheumatic drugs (DMARDs) were pooled across five Phase 3 studies. Phase 3 patients received tofacitinib 5 or 10mg twice daily (BID), adalimumab or placebo; patients in the single LTE study received tofacitinib 5 or 10mg BID; treatments were administered alone or with conventional synthetic DMARDs. Efficacy was reported up to 12 months (Phase 3) and 36 months (LTE) by American College of Rheumatology (ACR) 20/50/70 response rates, Disease Activity Score (DAS)28-4(erythrocyte sedimentation rate [ESR]) and Health Assessment Questionnaire-Disability Index (HAQ-DI). Incidence rates (IRs; patients with event/100 patient-years) of adverse events (AEs) of special interest were reported. The Phase 3 studies randomized 496 LA patients; the LTE study enrolled 756 LA patients from Phase 2 and Phase 3. In the Phase 3 studies, patients who received tofacitinib 5 and 10mg BID showed improvements vs placebo at Month 3 in ACR20 (68.9% and 75.7% vs 35.6%), ACR50 (45.8% and 49.7% vs 20.7%) and ACR70 (17.5% and 23.1% vs 6.9%) responses, mean change from baseline in HAQ-DI (-0.6 and -0.8 vs -0.3) and DAS28-4(ESR) score (-2.3 and -2.4 vs -1.4). The improvements were sustained up to Month 36 in the LTE study. In the Phase 3 studies, IRs with tofacitinib 5 and 10mg BID and placebo were 7.99, 6.57 and 9.84, respectively, for SAEs, and 3.87, 5.28 and 3.26 for discontinuation due to AEs. IRs of AEs of special interest in tofacitinib-treated LA patients were similar to the global population. In Phase 3 and LTE studies in LA patients with RA, tofacitinib demonstrated efficacy up to 36 months with a manageable safety profile up to 60 months, consistent with the overall tofacitinib

    Long-term synaptic plasticity is a major cellular substrate for learning, memory, and behavioral adaptation. Although early examples of long-term synaptic plasticity described a mechanism by which postsynaptic signal transduction was potentiated, it is now apparent that there is a vast array of mechanisms for long-term synaptic plasticity that involve modifications to either or both the presynaptic terminal and postsynaptic site. In this article, we discuss current and evolving approaches to identify presynaptic mechanisms as well as discuss their limitations. We next provide examples of the diverse circuits in which presynaptic forms of long-term synaptic plasticity have been described and discuss the potential contribution this form of plasticity might add to circuit function. Finally, we examine the present evidence for the molecular pathways and cellular events underlying presynaptic long-term synaptic plasticity. PMID:24146648

    2011-01-01

    Background Outcome data on two-stage revision surgery for deep infection after septic hip arthritis are limited and inconsistent. This study presents the medium-term results of a new, standardized two-stage arthroplasty with preformed hip spacers and cementless implants in a consecutive series of adult patients with septic arthritis of the hip treated according to a same protocol. Methods Nineteen patients (20 hips) were enrolled in this prospective, non-randomized cohort study between 2000 and 2008. The first stage comprised femoral head resection, debridement, and insertion of a preformed, commercially available, antibiotic-loaded cement hip spacer. After eradication of infection, a cementless total hip arthroplasty was implanted in the second stage. Patients were assessed for infection recurrence, pain (visual analog scale [VAS]) and hip joint function (Harris Hip score). Results The mean time between first diagnosis of infection and revision surgery was 5.8 ± 9.0 months; the average duration of follow up was 56.6 (range, 24 - 104) months; all 20 hips were successfully converted to prosthesis an average 22 ± 5.1 weeks after spacer implantation. Reinfection after total hip joint replacement occurred in 1 patient. The mean VAS pain score improved from 48 (range, 35 - 84) pre-operatively to 18 (range, 0 - 38) prior to spacer removal and to 8 (range, 0 - 15) at the last follow-up assessment after prosthesis implantation. The average Harris Hip score improved from 27.5 before surgery to 61.8 between the two stages to 92.3 at the final follow-up assessment. Conclusions Satisfactory outcomes can be obtained with two-stage revision hip arthroplasty using preformed spacers and cementless implants for prosthetic hip joint infections of various etiologies.

    Nineteen patients (11 women and eight men) aged 20-68 received long-term parenteral nutrition, mostly at home, for six to 63 months (mean 19 months). Indications for LTPN were extensive, active Crohn's disease in three patients, intestinocutaneous fistulas in three, and short-bowel syndrome in the remaining 13 patients. Subclavian or intra-atrial (Broviac) catheters were most commonly used, for which the average life was four and seven months respectively. Complications of long-term parenteral nutrition included pneumothorax in four out of 48 subclavian vein punctures. Catheter-induced thrombosis of central veins was shown by phlebography 17 times in nine patients, and eight episodes of total occlusion occurred. Two of these patients had pulmonary infarction. Nineteen episodes of catheter sepsis occurred in 11 patients, but only one was fatal. Complications related to intestinal disease included intra-abdominal abscesses and intestinal fistulas, and disturbances of liver function. Five patients died, though in only two was death related to long-term parenteral nutrition. One of these patients died from catheter sepsis, the other had subdural haematoma possibly caused by anticoagulant treatment. Eight of the 14 surviving patients still needed parenteral nutrition. All received a disability pension, but six had an acceptable quality of life with almost normal social activities. Despite problems such as difficulties in maintaining standardised infusion programmes, it was concluded that long-term parenteral nutrition at home is practicable and consistent with an acceptable quality of life.

  13. Long-term data archiving

    Long term data archiving has much value for chemists, not only to retain access to research and product development records, but also to enable new developments and new discoveries. There are some recent regulatory requirements (e.g., FDA 21 CFR Part 11), but good science and good business both benefit regardless. A particular example of the benefits of and need for long term data archiving is the management of data from spectroscopic laboratory instruments. The sheer amount of spectroscopic data is increasing at a scary rate, and the pressures to archive come from the expense to create the data (or recreate it if it is lost) as well as its high information content. The goal of long-term data archiving is to save and organize instrument data files as well as any needed meta data (such as sample ID, LIMS information, operator, date, time, instrument conditions, sample type, excitation details, environmental parameters, etc.). This editorial explores the issues involved in long-term data archiving using the example of Raman spectral databases. There are at present several such databases, including common data format libraries and proprietary libraries. However, such databases and libraries should ultimately satisfy stringent criteria for long term data archiving, including readability for long times into the future, robustness to changes in computer hardware and operating systems, and use of public domain data formats. The latter criterion implies the data format should be platform independent and the tools to create the data format should be easily and publicly obtainable or developable. Several examples of attempts at spectral libraries exist, such as the ASTM ANDI format, and the JCAMP-DX format. On the other hand, proprietary library spectra can be exchanged and manipulated using proprietary tools. As the above examples have deficiencies according to the three long term data archiving criteria, Extensible Markup Language (XML; a product of the World Wide Web

    Direct plating of synovial fluid (SF) on agar-based media often fails to identify pathogens in septic arthritis (SA). We developed a PCR assay for the simultaneous detection of Kingella kingae and Staphylococcus aureus from SF to evaluate molecular detection in SF and to estimate the incidence of K. kingae in SA in North America. The assay was based on detection of the cpn60 gene of K. kingae and the spa gene of S. aureus in multiplex real-time PCR. K. kingae was identified in 50% of patients between 0 and 5 yr of age (n=6) but not in any patients >18 yr old (n=105). Direct plating of SF on agar-based media failed to detect K. kingae in all samples. The PCR assay was inferior to the culture-based method for S. aureus, detecting only 50% of culture-positive cases. Our findings suggest that K. kingae is a common pathogen in pediatric SA in North America, in agreement with previous reports from Europe. PCR-based assays for the detection of K. kingae may be considered in children with SA, especially in those with a high degree of clinical suspicion. PMID:24982837

    Due to impairment of immunity and metabolism, cirrhotic patients are prone to infection, osteoporosis, and osteonecrosis. However, it is unknown if cirrhotic patients are prone to native septic arthritis (NSA). To assess the occurrence of NSA between cirrhotic and non-cirrhotic patients. We used the Taiwan National Health Insurance Database to enrol 35,106 cirrhotic patients and 33,457 non-cirrhotic patients from January 1, 2004 to December 31, 2004. The medical record of each patient was individually followed for a 3-year period. There were 341 (0.5%) patients having NSA in a follow-up period of 3 years: 214 cirrhotic and 127 non-cirrhotic patients. The incidence density of hospitalisation for NSA was 2.03 episodes/1000 person-years in cirrhotic patients, and 1.27 episodes/1000 person-years in non-cirrhotic patients. After adjustment for age, gender, and other comorbid disorders, Cox's regression analysis showed that cirrhotic patients had a higher occurrence of NSA than non-cirrhotic patients(hazard ratio (HR) = 1.51, 95% confidence interval (CI) = 1.19-1.90; p = 0.001). The patients with complicated cirrhosis were more prone to have NSA than those with non-complicated cirrhosis (HR = 1.46, 95% CI = 1.09-1.96, p = 0.011). This analysis demonstrates that cirrhotic patients have a higher risk of NSA, particularly those with complicated cirrhosis.

  17. Septic arthritis of the knee: Presentation of a novel irrigation-suction system tested in a cadaver study

    PubMed Central

    2011-01-01

    Background The established treatment for bacterial arthritis of the knee joint is arthroscopic surgery with irrigation and debridement. The aim of this article is to summarize the relevant data in treating bacterial arthritis of the knee joint, and based on these findings to present a novel irrigation suction system, tested in a cadaver study, as an additional tool in the postoperative treatment phase of arthroscopic surgery for knee joint infections. Method The novel automated irrigation-suction system presented here was compared to conventional continuous suction irrigation in a total of six knee joints. All knee joints were filled with 80 ml methylene blue stain and rinsed by two different methods. Fluid specimens were taken after ten and twenty minutes to be compared by photometric extinction measurement at a wave length of 500 nm. Results After ten minutes, the average extinction was e1C = 0.8 for the continuous suction irrigation and e1N = 0.4 for the novel irrigation-suction system. After twenty minutes, we recorded an average extinction of e2C = 0.3 for continuous suction irrigation and e2N = 0.001 for the novel irrigation-suction system. The students t-test revealed superior results after ten and twenty minutes of washing out the knee joints with a p < 0.001 for the novel irrigation-suction system. Conclusion A novel irrigation-suction system may be an effective tool for postoperative knee joint irrigation in arthroscopic therapy for bacterial arthritis of the knee. Further animal studies are needed to verify the effects in vivo. PMID:21819619

    Monoarticular arthritis is inflammation characterized by joint pain, swelling, and sometimes periarticular erythema. Although chronic causes are seen, the onset is often acute. An infected joint can quickly lead to permanent damage, making it a medical emergency. However, acute gout presenting as monoarticular arthritis is often so uncomfortable it requires urgent attention. Monoarticular crystalline arthritis is common and a septic joint is a medical emergency so it is no surprise that these diagnoses come to mind with complaint of inflammation in 1 joint. However, there are many causes of monoarticular arthritis that clinicians must consider. Copyright © 2016 Elsevier Inc. All rights reserved.

    We document the case of a 7-year-old boy who presented with pain in his left ear and trismus after a diagnosis of acute otitis media one week previously. His blood inflammatory markers were raised and magnetic resonance imaging (MRI) showed significant left temporomandibular joint effusion and partial attenuation of the left mastoid. A clinical diagnosis of septic arthritis of the TMJ was made and the patient was commenced on broad-spectrum antibiotics. Analysis using real time PCR enabled identification of the offending organism, confirmation of the diagnosis and antibiotic treatment to be specifically tailored for treatment.

    This article provides an overview of the status of long-term oxygen therapy (LTOT). In the United States, payment cutbacks are occurring as a result of congressionally mandated competitive bidding and capped rental programs. These Medicare programs are discussed. These legislative and regulatory changes may result in reduced patient access to appropriate oxygen-delivery systems that meet medical needs, including optimal ambulation. Prescribing LTOT is addressed in this article, as is the need for adequate patient education. The importance of appropriate monitoring and reassessment is presented. The use of an LTOT collaborative care model is discussed. Although the new intermittent flow oxygen-delivery systems have potential benefits, there is consensus that each patient should be tested on the specific device because of variability in delivery and patient response. Feasible locations for patient education and monitoring are identified.

    To study the effects of infrared (IR) Sauna, a form of total-body hyperthermia in patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS) patients were treated for a 4-week period with a series of eight IR treatments. Seventeen RA patients and 17 AS patients were studied. IR was well tolerated, and no adverse effects were reported, no exacerbation of disease. Pain and stiffness decreased clinically, and improvements were statistically significant (p < 0.05 and p < 0.001 in RA and AS patients, respectively) during an IR session. Fatigue also decreased. Both RA and AS patients felt comfortable on average during and especially after treatment. In the RA and AS patients, pain, stiffness, and fatigue also showed clinical improvements during the 4-week treatment period, but these did not reach statistical significance. No relevant changes in disease activity scores were found, indicating no exacerbation of disease activity. In conclusion, infrared treatment has statistically significant short-term beneficial effects and clinically relevant period effects during treatment in RA and AS patients without enhancing disease activity. IR has good tolerability and no adverse effects.

    2005-01-01

    Our long-term goal is to establish a reliable system for monitoring surface salinity around the global ocean. Salinity is a strong indicator of the freshwater cycle and has a great influence on upper ocean stratification. Global salinity measurements have potential to improve climate forecasts if an observation system can be developed. This project is developing a new internal field conductivity cell that can be protected from biological fouling for two years. Combined with a temperature sensor, this foul-proof cell can be deployed widely on surface drifters. A reliable in-situ network of surface salinity sensors will be an important adjunct to the salinity sensing satellite AQUARIUS to be deployed by NASA in 2009. A new internal-field conductivity cell has been developed by N Brown, along with new electronics. This sensor system has been combined with a temperature sensor to make a conductivity - temperature (UT) sensor suitable for deployment on drifters. The basic sensor concepts have been proven on a high resolution CTD. A simpler (lower cost) circuit has been built for this application. A protection mechanism for the conductivity cell that includes antifouling protection has also been designed and built. Mr. A.Walsh of our commercial partner E-Paint has designed and delivered time-release formulations of antifoulants for our application. Mr. G. Williams of partner Clearwater Instrumentation advised on power and communication issues and supplied surface drifters for testing.

    During the last decades, non-invasive mechanical ventilation has evolved into one of the most evidence-based areas of respiratory medicine, with many indications in acute or chronic respiratory failure. From the first application of negative pressure models during poliomyelitis epidemics to the new sophisticated positive pressure models, and the development of the “intelligent ventilators”, there has been a long time course. Undoubtedly the spur was given by better understanding of respiratory physiology during sleep and the shift of healthcare towards a chronic base. Novel randomized controlled trials (RCTs) established the use of NIV in acute respiratory failure due to exacerbations of COPD, as well as acute pulmonary edema and weaning from invasive mechanical ventilation. Long-term NIV has been used in neuromuscular diseases for many decades, first in Duchenne muscular dystrophy, and then spreading to other disorders of this category, increasing survival in inherited neuromuscular diseases. NIV should be initiated early in the course of the disease, when symptomatic nocturnal hypoventilation is detected. Combined with cough augmentation (physiotherapy, insufflation-exsufflation devices) and percutaneous gastrostomy feeding, it can delay tracheostomy and invasive ventilation. In ALS patients NIV improves the quality of life and increases survival, especially when there is no bulbar involvement. The right time to initiate ventilation in this group of patients is not well established since it is difficult to detect signs and symptom of respiratory impairment. Patients seem to benefit from an early application of NIV, and their personal decisions should always be considered before any intervention. In patients with chest wall disorders NIV—despite the fact that RCTs are lacking—has proved its value in many uncontrolled trials and numerous reports. It seems to improve the work of breathing, sleep architecture, nocturnal and daytime arterial blood gases. The

    The long-term results with large fenestra stapedectomy with vein graft and Teflon piston are compared with results with the small fenestra stapedectomy with teflon piston directly into the vestibule. There were 1,943 operations in the former group and 2,155 in the latter when compared in 1970. One hundred consecutive patients from the beginning of each group with follow-up to present were compared. Results were generally the same with no great change in 15 and 20 years as compared to those at 5 years. The complication of perilymph fistula was caused by creating an opening in the footplate much larger than the prosthesis and was eliminated by interposing a living oval window seal if the opening was much larger than the prosthesis and a flap of lining membrane from the promontory when it was not. Other factors that influence a good result are discussed, including the type and the diameter of the piston used, the type of living oval window seal and the method of attachment to the incus. The small fenestra operation was found to be superior to the large, not only for the hearing gain achieved, but the case of performance and the freedom from complications due to migration of the prosthesis and/or the oval window seal. At present we have done about all that can be done for the conductive components. What remains is the sensorineural component which our studies indicate may be due to an autoimmune response.

    The scope of this activity is to assess the long-term corrosion properties of metallic materials under consideration for fabricating waste package containers. Three classes of metals are to be assessed: corrosion resistant, intermediate corrosion resistant, and corrosion allowance. Corrosion properties to be evaluated are general, pitting and crevice corrosion, stress-corrosion cracking, and galvanic corrosion. The performance of these materials will be investigated under conditions that are considered relevant to the potential emplacement site. Testing in four aqueous solutions, and vapor phases above them, and at two temperatures are planned for this activity. (The environmental conditions, test metals, and matrix are described in detail in Section 3.0.) The purpose and objective of this activity is to obtain the kinetic and mechanistic information on degradation of metallic alloys currently being considered for waste package containers. This information will be used to provide assistance to (1) waste package design (metal barrier selection) (E-20-90 to E-20-92), (2) waste package performance assessment activities (SIP-PA-2), (3) model development (E-20-75 to E-20-89). and (4) repository license application.

    1997-12-31

    Beginning in 1991 a series of laboratory tests and small scale field trials were initiated to test the performance of an innovative permeable reactive barrier for treatment of nitrate from septic systems. The barrier promotes denitrification by providing an energy source in the form of solid organic carbon mixed into the porous media material. Advantages of the system for nitrate treatment are that the reaction is passive and in situ and it is possible to incorporate sufficient carbon mass in conveniently sized barriers to potentially provide treatment for long periods (decades) without the necessity for maintenance. However, longevity can only be demonstrated by careful long term monitoring of field installations. This paper documents four years of operating history at three small scale field trials; two where the denitrification barrier is installed as a horizontal layer positioned in the unsaturated zone below conventional septic system infiltration beds and one where the barrier is installed as a vertical wall intercepting a septic system plume at a downgradient location. The barriers have successfully attenuated 50-100% of NO{sup -}{sub 3}-N levels of up to 170 mg/L and treatment has remained consistent over the four year period in each case, thus considerable longevity is indicated. Other field trials have demonstrated this technology to be equally effective in treating nitrogen contamination from other sources such as landfill leachate and farm field runoff.

    Our objectives were to assess the clinical and microbiological aspects of septic osteoarthritis in children admitted to our center from 1987 until July 1997 and to determine the sensitivity of ultrasound in this age group. The medical records of 36 children diagnosed as having septic osteoarthritis of the hip were reviewed retrospectively. The diagnosis had been based on clinical criteria, along with synovectomy and drainage of purulent material from the affected joint. An X-ray and/or ultrasound had been performed when the diagnosis was suspected. Nineteen children were diagnosed during the neonatal period, 8 between the ages of 1 and 12 months and 9 older than one year of age. Mean age at diagnosis was 16.8 +/- 6.2 months (median 29 days, range 6 days to 13 years). The hip was involved in 32 children, the ankle in 3 and the elbow in 1. A microbiological diagnosis was achieved in 22 cases (61%) by culture from blood, CSF, and/or synovial fluid. The most common isolates were Gram positive cocci (S. aureus in 9 cases and coagulase negative Staphylococcus in 3). The diagnostic value of the X-rays was very low (18%). The ultrasound was initially considered abnormal in 64.5% of the patients, with a lower sensitivity in the neonatal period. After a mean follow-up period of 36 months, the outcome was good in 86% of the cases, although three children continue with sequelae. Two preterm infants died due to sepsis associated with the osteoarthritis. At the time of diagnosis of septic arthritis of the hip, the ultrasound is frequently normal. Due to the poor outcome when there is a delay in surgery, we suggest immediate synovectomy and drainage when there is clinical suspicion of septic arthritis despite an apparently normal ultrasound.

    Abstract The recent large decrease in splenectomy use for chronic immune thrombocytopenia (ITP) is partly due to still-unsolved questions about long-term safety. We performed the first single-center exposed/unexposed cohort study evaluating the long-term incidence of splenectomy complications in patients with primary ITP. Overall, 83 patients who underwent splenectomy more than 10 years ago (exposed) were matched with 83 nonsplenectomized patients (unexposed) on the date of ITP diagnosis ±5 years, age and gender. After a median follow-up of 192 months (range 0.5–528), 43 patients (52%) achieved overall response after splenectomy. Splenectomized patients experienced more venous thromboembolism (VTE) than controls (n = 13 vs n = 2, P = 0.005). On multivariate analysis, splenectomy was an independent risk factor of VTE (hazard ratio = 4.006, P = 0.032 [95% confidence interval: 1.13–14.21]). Splenectomized patients presented more severe infections on long-term follow-up: all required hospitalization, and 5/26 (19%) infections led to severe sepsis or septic shock and to death for 3 cases (none in controls). However, the incidence of malignancy was similar in both groups, as was cardiovascular risk, which appeared to be related more to ITP than splenectomy. Finally, splenectomy did not significantly decrease overall survival. Despite the risk of thrombosis and severe sepsis, splenectomy remains an effective and curative treatment for ITP. PMID:27902585

    Twelve years after its introduction, long-term care insurance is back on the agenda and up for political reform. This paper shows why long-term care insurance needs to be reformed. The two central aspects on which reform projects focus are addressed: firstly, the structural improvement of nursing care and long-term care insurance and, secondly, the creation of a sustained financing. The principal conclusion is that, while there is a broad consensus about the structural improvement of long-term care insurance, opinions differ widely in the matter of its sustained financing. As a consequence, a coherent financing concept has yet to emerge.

    The purpose of this investigation was to assess the clinical characteristics, therapeutic aspects, and outcome of arthritis related to invasive meningococcal disease (IMD). All episodes of bacterial meningitis and IMD are recorded systematically. We selected all episodes of IMD, with or without meningitis, that presented arthritis. From 1977 to 2010, 522 episodes of IMD were treated. Thirty-nine of these (7.5 %, 26 women, mean age 33 years) presented arthritis. Of these 39, 37 (95 %) presented skin lesions and 31 (79 %) had meningitis. Twenty (51 %) had positive blood cultures and six (15 %) had shock. No differences were found in skin lesions, shock, or bacteremia compared to cases without arthritis. In contrast to other septic forms, arthritis related to IMD was cured with short antibiotic therapy and without surgical drainage. There was no mortality. All patients recovered and none presented joint sequelae; however, 13 adult patients (33 %) required long-term treatment with steroids due to persistent symptoms. Arthritis related to IMD most frequently affects the knees and ankles, and may be a cause of fever relapse. Short antibiotic therapy is enough in all cases and surgical drainage is not needed. In some adult patients, especially those over 50 years of age, evolution is torpid and steroid therapy may be required in order to achieve recovery.

    Purpose to evaluate the differences in clinical outcome and survivorship of three different mobile bearings for total knee arthroplasty. Methods a retrospective study was conducted in 60 patients (53 females, 7 males, mean age: 68 years and 5 months) each submitted to total knee replacement using one of the three different mobile bearings of the LCS system (Depuy Johnson & Johnson, Warsaw, IN). The diagnosis was knee osteoarthritis in 57 cases and rheumatoid arthritis in three cases. Three different groups of 20 cases each were identified: total knee arthroplasties with mobile menisci (group 1); total knee arthroplasties with the rotating platform (group 2); and total knee arthroplasties with the anteroposterior glide platform (group 3). As regards the component fixation, 33 implants were cementless, three were cemented, and in 24 only the tibial component was cemented. The patella was not replaced. Results although the duration of follow-up differed between the three groups, the clinical and radiological results at final follow-up showed no revision of femoral and/or tibial components for mechanical or septic reasons, and no signs of impending failure. One meniscal bearing, showing polyethylene wear after 17 years, was successfully replaced. Conclusions the present retrospective study confirmed the long-term effectiveness of knee implants with mobile bearings, in which the congruity of the surfaces makes it possible to overcome the problem of high contact stresses that may result in polyethylene wear and osteolysis; at the same time, these implants eliminate constraint forces thereby reducing the risk of mechanical loosening.

    Kingella kingae is a bacterium that colonizes the upper respiratory tract. Despite its low pathogenicity in this location, previous respiratory pathological processes may favor its systemic spread causing bone and joint infections, mainly in children under five years. It can be considered an emerging pathogen in osteoarticular infection in pediatric patients. We report the case of a two-year-old girl with hips pain and limitation of both abduction and extension, and fever.

    The Latarjet procedure is effective in managing anterior glenohumeral instability in the short term, but there is concern for postoperative arthritis. The purpose of this study was to evaluate the long-term functional outcome after the Latarjet procedure and to assess the prevalence of and risk factors for glenohumeral arthritis after this procedure. A retrospective review was conducted of 68 Latarjet procedures at a mean of 20 years postoperatively. The mean age at surgery was 29.4 years. Functional outcome was determined by the Rowe score, subjective shoulder value, and recurrence of instability. Preoperative arthritis and postoperative radiographs were reviewed to evaluate the development or progression of arthritis. The mean Rowe score increased from 37.9 preoperatively to 89.6 at final follow-up (P < .001). The mean subjective shoulder value was 90.9% at final follow-up. The postoperative rate of recurrence was 5.9%. Of the 60 shoulders without arthritis preoperatively, 12 (20%) had developed arthritis at final follow-up. Among the 8 shoulders with preoperative arthritis (all stage 1), 4 (50%) demonstrated progression of arthritis at final follow-up. Overall, postoperative arthritis was stage 1 in 14.7%, stage 2 in 5.9%, and stage 3 in 8.8% of cases; no stage 4 arthritis was observed. Risk factors for postoperative arthritis were older age, high-demand sports activity, and lateral overhang of coracoid bone graft. The Latarjet procedure provides excellent long-term outcomes in the treatment of recurrent anterior glenohumeral instability. Twenty years after the Latarjet procedure, arthritis may develop or progress in 23.5% of cases, but the majority of arthritis is mild.

    Everyone agrees that insurance for long-term care is inadequate in the United States. Disagreement exists, however, on whether such insurance should be provided through the private or public sector. Private insurance generally uses the experience-rating principle that persons with higher risk of illness are charged higher premiums. For private insurance for long-term care, this principle creates a dilemma. Most policies will be purchased by the elderly; yet, because the elderly have a high risk of needing long-term care, only about 20% of them can afford the cost of premiums. A public-private partnership by which the government partially subsidizes private long-term-care insurance is unlikely to resolve this dilemma. Only a social insurance program for long-term care can provide universal, affordable, and equitable coverage. PMID:8128712

    To evaluate the long-term results of unicompartmental knee joint alloplasty (UKA) in a group of 21 patients. On the basis of their own results and literature data, the authors discuss effective strategies for treatment of unicompartmental osteoarthritis of the knee joint. A group of 21 patients, who were implanted a total of 22 unicompartmental knee replacements, type St. Georg, Waldemar Link, between 1986 and 1992, were followed-up till 2002. Since two patients living permanently abroad were excluded, the group at the final evaluation consisted of 19 patients with a total of 20 knee replacements. In 2002, all patients were clinically and radiologically examined. They were interviewed about their subjective evaluation of the knee joint after alloplasty, and clinical and functional findings were assessed. The evaluation of long-term results was based on The Knee Society Clinical Rating System. The average Knee Score value was 84 points and average Function Score value was 78 points. Out of the 20 knee replacements evaluated, only one failure of UKA was recorded at 9 years after the primary implantation. The authors discuss the current state of treatment in unicompartmental knee arthritis and present several different views based on literature sources. Opinions on indications for specific surgical methods are still controversial. The authors draw attention to comparisons of long-term results between patients with UKA and patients who underwent high tibial valgus osteotomy or total knee replacement. They discuss the advantages and disadvantages of UKA in comparison with the other therapies. They also pay some attention to repeat surgery in failed UKA. UKA implantation is a surgical method of managing unicompartmental arthritis of the knee joint. The results presented by the authors and corroborated by many literature data provide evidence that UKA is of great importance in the treatment of unicompartmental knee arthritis.

    In the 1990s, acute care hospitals in the United States encountered an unstable operating environment created by a series of transformations in the health care delivery system and long-term-care market. Confronted with an array of economic pressures and demographic changes, hospitals were motivated to engage in long-term-care diversification, such as establishing a long-term-care unit or providing home health services, as a means of entering new markets and ensuring financial stability. This article examines the organizational, market, and community factors associated with this strategic activity among a national sample of urban and rural hospitals.

    Abortion-related deaths, which account for 47% of total maternal mortality in the world, result primarily from sepsis and are widespread in developing countries where abortion is illegal or inaccessible. Septic abortion offers opportunities for prevention on the primary, secondary, and tertiary level of medial care. Primary prevention of septic abortion encompasses the provision of effective contraception, provision of safe and legal abortion in cases of contraceptive failure, and appropriate medical management of abortion. Secondary prevention involves the prompt diagnosis of endometriosis and effective treatment to avert more serious infection. The diagnosis of septic abortion should be considered when women of reproductive age present to health facilities with vaginal bleeding, lower abdominal pain, and fever. Tertiary prevention is aimed at avoiding the serious complications of postabortal infection, including hysterectomy and death. Women with high fever, pelvic peritonitis, and tachycardia should undergo uterine evacuation and parental antibiotic therapy. Supportive care for cardiovascular system and other organs may be essential. The medical technology needed to avert serious complications and deaths from septic abortion is available. Lacking is a political commitment on the part of many governments and health care agencies to address this avoidable contributor to maternal morbidity and mortality.

  11. Septic Shock

    2015-01-01

    IMPORTANCE Septic shock is a clinical emergency that occurs in more than 230 000 US patients each year. OBSERVATIONS AND ADVANCES In the setting of suspected or documented infection, septic shock is typically defined in a clinical setting by low systolic (≤90 mm Hg) or mean arterial blood pressure (≤65 mm Hg) accompanied by signs of hypoperfusion (eg, oliguria, hyperlactemia, poor peripheral perfusion, or altered mental status). Focused ultrasonography is recommended for the prompt recognition of complicating physiology (eg, hypovolemia or cardiogenic shock), while invasive hemodynamic monitoring is recommended only for select patients. In septic shock, 3 randomized clinical trials demonstrate that protocolized care offers little advantage compared with management without a protocol. Hydroxyethyl starch is no longer recommended, and debate continues about the role of various crystalloid solutions and albumin. CONCLUSIONS AND RELEVANCE The prompt diagnosis of septic shock begins with obtainment of medical history and performance of a physical examination for signs and symptoms of infection and may require focused ultrasonography to recognize more complex physiologic manifestations of shock. Clinicians should understand the importance of prompt administration of intravenous fluids and vasoactive medications aimed at restoring adequate circulation, and the limitations of protocol-based therapy, as guided by recent evidence.

  13. Long Term Outcomes after Pediatric Liver Transplantation

    PubMed Central

    2013-01-01

    Long term outcomes after liver transplantation are major determinants of quality of life and of the value of this heroic treatment. As short term outcomes are excellent, our community is turning to take a harder look at long term outcomes. The purpose of this paper is to review these outcomes, and highlight proposed treatments, as well as pressing topics needing to be studied. A systemic review of the English literature was carried in PubMed, covering all papers addressing long term outcomes in pediatric liver transplant from 2000-2013. Late outcomes after pediatric liver transplant affect the liver graft in the form of chronic liver dysfunction. The causes include rejection particularly humoral rejection, but also de novo autoimmune hepatitis, and recurrent disease. The metabolic syndrome is a major factor in long term cardiovascular complication risk. Secondary infections, kidney dysfunction and malignancy remain a reality of those patients. There is growing evidence of late cognitive and executive function delays affecting daily life productivity as well as likely adherence. Finally, despite a good health status, quality of life measures are comparable to those of children with chronic diseases. Long term outcomes are the new frontier in pediatric liver transplantation. Much is needed to improve graft survival, but also to avoid systemic morbidities from long term immunosuppression. Quality of life is a new inclusive measure that will require interventions and innovative approaches respectful not only on the patients but also of their social circle. PMID:24511516

    For more than two decades, sepsis was defined as a microbial infection that produces fever (or hypothermia), tachycardia, tachypnoea and blood leukocyte changes. Sepsis is now increasingly being considered a dysregulated systemic inflammatory and immune response to microbial invasion that produces organ injury for which mortality rates are declining to 15–25%. Septic shock remains defined as sepsis with hyperlactataemia and concurrent hypotension requiring vasopressor therapy, with in-hospital mortality rates approaching 30–50%. With earlier recognition and more compliance to best practices, sepsis has become less of an immediate life-threatening disorder and more of a long-term chronic critical illness, often associated with prolonged inflammation, immune suppression, organ injury and lean tissue wasting. Furthermore, patients who survive sepsis have continuing risk of mortality after discharge, as well as long-term cognitive and functional deficits. Earlier recognition and improved implementation of best practices have reduced in-hospital mortality, but results from the use of immunomodulatory agents to date have been disappointing. Similarly, no biomarker can definitely diagnose sepsis or predict its clinical outcome. Because of its complexity, improvements in sepsis outcomes are likely to continue to be slow and incremental.

    The results for long-term symptom relief after septoplasty are contradictory in reviewed publications but the findings suggest that results are unsatisfactory. In this study, we analyzed and compared short- and long-term symptom relief after septoplasty and factors possibly associated with symptom relief. 111 patients that underwent septoplasty between 2008 and 2010 were included in the study. Medical charts were reviewed for preoperative characteristics and assessments. Data on short-term symptom relief (6 months) were retrieved from the Swedish National Quality Registry for Septoplasty; data on long-term symptom relief (34-70 months) were collected through a questionnaire. Upon the 34-70 month follow-up, 53% of the patients reported that symptoms either remained or had worsened and 83% reported nasal obstruction. Degree of symptom relief was significantly higher among patients not reporting nasal obstruction than among patients reporting nasal obstruction at long-term follow-up. The proportion of patients that reported "my symptoms are gone" declined from 53% after 6 months to 18% after 34-70 months. None of the factors taken into consideration, age at surgery, gender, follow-up time, primary operation/reoperation, history of nasal trauma, self-reported allergy, rhinometric obstruction, or same sided rhinometric, clinical and subjective nasal obstruction were associated with symptom relief. The long-term results after septoplasty are unsatisfactory. A majority of patients report that their symptoms remain after septoplasty.

  16. Septic Shock

    Lansing, Allan M.

    Septic shock may be defined as hypotension caused by bacteremia and accompanied by decreased peripheral blood flow, evidenced by oliguria. Clinically, a shaking chill is the warning signal. The immediate cause of hypotension is pooling of blood in the periphery, leading to decreased venous return: later, peripheral resistance falls and cardiac failure may occur. Irreversible shock is comparable to massive reactive hyperemia. Reticuloendothelial failure, histamine release, and toxic hypersensitivity may be factors in the pathogenesis of septic shock. Adrenal failure does not usually occur, but large doses of corticosteroid are employed therapeutically to counteract the effect of histamine release or hypersensitivity to endotoxin. The keys to successful therapy are time, antibiotics, vasopressors, cortisone and correction of acidosis. PMID:14063936

    Autoimmune pancreatitis (AIP) has been considered a favorable-prognosis disease; however, currently, there is limited information on natural course of AIP during long-term follow-up. Recently published studies regarding the long-term outcomes of AIP has demonstrated the developments of pancreatic stone formation, exocrine insufficiency, and endocrine insufficiency are observed in 5%-41%, 34%-82%, and 38%-57% of patients having the disease. Furthermore, the incidence rate of developing pancreatic cancer ranges from 0% to 4.8% during the long-term follow-up. The event of death from AIP-related complications other than accompanying cancer is likely to be rare. During follow-up of AIP patients, careful surveillance for not only relapse of the disease but also development of complications at regular intervals is needed. PMID:27678359

    The overall incidence in gonorrhoea of septic gonococcal dermatitis was found to be 1.9% (3% for the females and 0.7% for the males). In 23 patients the common presenting symptoms were arthritis or arthralgia and bouts of fever, but the characteristic skin lesions served as an early clue to the diagnosis, and Neisseria gonorrhoeae was isolated from the genitourinary tract or from the blood. With the use of immunofluorescent techniques gonococci were also found in smears prepared from the skin lesions. An immune response to gonococci was found with the complement fixation technique in 90% of the patients. The response to treatment with penicillin was prompt, with complete relief from joint pains and fever, usually within two to seven days. The skin lesions faded within a few days, but scars could be observed for up to four weeks.

    The business valuation industry generally uses at least one of three basic approaches to value a long-term care facility: the cost approach, sales comparison approach, or income approach. The approach that is chosen and the resulting weight that is applied to it depend largely on the circumstances involved. Because a long-term care facility is a business enterprise, more weight usually is given to the income approach which factors into the estimate of value both the tangible and intangible assets of the facility.

    Background Severe shock is a life-threatening condition with very high short-term mortality. Whether the long-term outcomes among survivors of severe shock are similar to long-term outcomes of other critical illness survivors is unknown. We therefore sought to assess long-term survival and functional outcomes among 90-day survivors of severe shock and determine whether clinical predictors were associated with outcomes. Methods Seventy-six patients who were alive 90 days after severe shock (received ≥1 mcg/kg/min of norepinephrine equivalent) were eligible for the study. We measured three-year survival and long-term functional outcomes using the Medical Outcomes Study 36-Item Short-Form Health Survey, the EuroQOL 5-D-3L, the Hospital Anxiety and Depression Scale, the Impact of Event Scale-Revised and an employment instrument. We also assessed the relationship between in-hospital predictors and long-term outcomes. Results The mean long-term survival was 5.1 years: 82% (62/76) of patients survived, of whom 49 were eligible for follow-up. Patients who died were older than patients who survived. Thirty-six patients completed a telephone interview a mean of five years after hospital admission. The patients’ Physical Functioning scores were below US population norms (p<0.001), whereas mental health scores were similar to population norms. Nineteen percent of the patients had symptoms of depression, 39% had symptoms of anxiety and 8% had symptoms of posttraumatic stress disorder. Thirty-six percent were disabled, and 17% were working full time. Conclusions Early survivors of severe shock had a high three-year survival rate. Patients’ long term physical and psychological outcomes were similar to those reported for cohorts of less severely ill ICU survivors. Anxiety and depression were relatively common, but only a few patients had symptoms of posttraumatic stress disorder.

    Several situations are potentially painful for fetuses, such as malformations and invasive procedures. Nociceptive pathways are known to be functional at 26 weeks. Even if it is not possible to evaluate the fetal experience of pain, it is essential to examine its immediate and long-term consequences. As early as the beginning of the second trimester, hemodynamic and hormonal responses are observed following fetal nociceptive stimulation, In experimental studies, long-term changes have been noted in the corticotrop axis, subsequent responses to pain, and behavior after perinatal nociceptive stimulation.

  8. Long-term studies of dopamine agonists.

    PubMed

    Hubble, Jean P

    2002-02-26

    Dopamine agonists have long been used as adjunctive therapy for the treatment of Parkinson's disease (PD). In more recent years these drugs have also been proved safe and effective as initial therapy in lieu of levodopa in the treatment of PD. Long-term levodopa therapy is associated with motor complications, including fluctuating response patterns and dyskinesia. By initially introducing a dopamine agonist as symptomatic drug therapy, it may be possible to postpone the use of levodopa and delay or prevent the development of motor complications. Recently, four clinical trials have explored this hypothesis by comparing the long-term response and side effects of levodopa with dopamine agonist therapy. The drugs studied have included ropinirole, pramipexole, cabergoline, and pergolide. In each of these projects, the occurrence of motor complications, such as wearing off and dyskinesia, was significantly less in the subjects assigned to initiation of therapy with a dopamine agonist. The addition of levodopa could be postponed by many months or even several years. Therefore, these long-term studies of dopamine agonists support the initiation of a dopamine agonist instead of levodopa in an effort to postpone levodopa-related motor complications. This therapeutic approach may be particularly appropriate in PD patients with a long treatment horizon on the basis of age and general good health. The extension phase of the long-term study comparing pramipexole with levodopa is ongoing, and follow-up information may help to establish the value of this treatment strategy.

    In the past 20 years, primary care physicians have greatly increased prescribing of long-term opioid therapy. However, the rise in opioid prescribing has outpaced the evidence regarding this practice. Increased opioid availability has been accompanied by an epidemic of opioid abuse and overdose. The rate of opioid addiction among patients receiving long-term opioid therapy remains unclear, but research suggests that opioid misuse is not rare. Recent studies report increased risks for serious adverse events, including fractures, cardiovascular events, and bowel obstruction, although further research on medical risks is needed. New data indicate that opioid-related risks may increase with dose. From a societal perspective, higher-dose regimens account for the majority of opioids dispensed, so cautious dosing may reduce both diversion potential and patient risks for adverse effects. Limiting long-term opioid therapy to patients for whom it provides decisive benefits could also reduce risks. Given the warning signs and knowledge gaps, greater caution and selectivity are needed in prescribing long-term opioid therapy. Until stronger evidence becomes available, clinicians should err on the side of caution when considering this treatment.

    Early functional outcome after restorative proctocolectomy and formation of an ileoanal pouch is known to be good, but there are minimal data on the long-term function of the pouch. The aim of this study was to look at the long-term functional outcome in patients who had undergone restorative proctocolectomy and formation of an ileoanal pouch. A total of 151 consecutive patients (96 males, 55 females) who underwent ileoanal pouch surgery between April 1983 and May 1993 were identified. Functional outcomes from the previous 12 months were appraised by a standardized questionnaire. The median age at surgery was 31 years (range, 6-63 years), with a median follow-up of 142 months (range, 100-221 months). Eighteen patients have had their pouches excised, with another patient being defunctioned. Therefore 19 patients (13 percent) had suffered pouch failure. Altogether, 115 patients were available for follow-up, and 98 patients (85 percent) returned questionnaires. The median pouch-emptying frequency was five times (range, 1-17) during the day and one time (range, 0-6) at night. A total of 74 percent of patients had perfect continence during the day. Most of the patients had no life-style restrictions related to the pouch, and 98 percent of patients would recommend a pouch to others. Long-term functional outcome after ileoanal pouch surgery is good in most patients. For patients requiring proctocolectomy, ileoanal pouch surgery can now be recommended as an excellent long-term option.

    This longitudinal study aims to investigate differences in long-term disability between social anxiety disorder (SAD), panic disorder with agoraphobia (PDA), panic disorder without agoraphobia (PD), generalized anxiety disorder (GAD) and multiple anxiety disorders (multiple AD), focusing on the effects of different course trajectories (remission, recurrence and chronic course) and specific symptom dimensions (anxiety arousal and avoidance behaviour). Data were used from participants with no psychiatric diagnosis (healthy controls, n = 647) or with a current anxiety disorder (SAD, n = 191; PDA, n = 90; PD, n = 84; GAD, n = 110; multiple AD, n = 480). Severity of anxiety arousal and avoidance behaviour symptoms was measured using the Beck Anxiety Inventory and the Fear Questionnaire. The World Health Organization Disability Assessment Schedule II was used to measure disability. Long-term disability was most prevalent in participants with SAD and multiple AD, and lowest in PDA and PD. GAD had an intermediate position. Anxiety arousal and avoidance behaviour were associated with more long-term disability in anxiety disorders than course trajectories. Various anxiety disorders have different disability levels over 4 years of time, therefore diagnostic distinction is important for treatment focus. Anxiety arousal and avoidance behaviour are major predictors for long-term disability in anxiety disorders.

    2016-04-01

    The greenschist in the Jinping II Hydropower Station in southwest China exhibits continuous creep behaviour because of the geological conditions in the region. This phenomenon illustrates the time-dependent deformation and progressive damage that occurs after excavation. In this study, the responses of greenschist to stress over time were determined in a series of laboratory tests on samples collected from the access tunnel walls at the construction site. The results showed that the greenschist presented time-dependent behaviour under long-term loading. The samples generally experienced two stages: transient creep and steady creep, but no accelerating creep. The periods of transient creep and steady creep increased with increasing stress levels. The long-term strength of the greenschist was identified based on the variation of creep strain and creep rate. The ratio of long-term strength to conventional strength was around 80% and did not vary much with confining pressures. A quantitative method for predicting the failure period of greenschist, based on analysis of the stress-strain curve, is presented and implemented. At a confining pressure of 40 MPa, greenschist was predicted to fail in 5000 days under a stress of 290 MPa and to fail in 85 days under the stress of 320 MPa, indicating that the long-term strength identified by the creep rate and creep strain is a reliable estimate.

  9. Workshop on long-term contraceptives.

    PubMed

    1996-01-01

    The National Population Council Secretariat (NPCS) of Ghana held a three-day workshop on long-term contraceptives in 1996 in collaboration with the Ministry of Health, the Association of Voluntary Surgical Contraception, and the Johns Hopkins Population Communication Services. The session was funded by USAID. The executive director of NPCS, Dr. Richard Turkson, said that the slow rate of contraceptive acceptance was an obstacle to population control despite political concern that rapid population growth exerted an adverse impact on the economy. Only 10% of married women were using long-term or permanent methods of contraception. The hope was voiced that the participants would devise practical and cost-effective education, information, and communication (IEC) strategies to boost the demand for long-term contraceptive methods among sexually active people in Ghana. It was essential that these strategies and activities were based on a realist assessment of the demographic and social situation of the country. The examination of case studies in cultures similar to Ghana would also offer valuable lessons. The factors that hinder the acceptance of long-term methods include misconceptions, myths, and false rumors rooted in a general lack of knowledge among the people. Participants were urged to come up with strategies to counter these problems, and service providers were encouraged to improve their knowledge about contraceptive methods and counseling skills. Male involvement in contraception was also advocated. Statistics show that most Ghanians practicing contraception were using short-term methods such as foaming tablets, pills, and condoms. However, it is necessary to shift to long-term methods such as injectables, implants, and sterilization in order to achieve significant reductions in fertility.

    Missions in space within the next two decades will be of longer duration than those carried out up to the present time, and the effects of such long-term flights on biological organisms are unknown. Results of biological experiments that have been performed to date cannot be extrapolated to results in future flights because of the unknown influence of adaptation over a long period of time. Prior experiments with Axolotl, fishes, and vertebrates by our research team (in part with sounding rockets) showed that these specimens did not appear to be suitable for long-term missions on which minimization of expense, technique, and energy is required. Subsequent investigations have shown the suitability of the leech (Hirudo medicinalis), which consumes blood of mammals up to ten times its own weight (1 g) and can live more than 2 years without further food supply. Emphasis in the experiments with Hirudo medicinalis is placed on metabolic rhythm and motility. Resorption and diffusion in tissue, development, and growth under long-term effects of cosmic proton radiation and zero-gravity are other focal points. The constancy of cellular life in the mature animals is a point in favor of these specimens. We have also taken into account the synergistic effects of the space environment on the problems just mentioned. The life-support system constructed for the leech has been tested successfully in four sounding rocket flights and, on that basis, has been prepared for a long-term mission. Long-term investigations out of the terrestrial biosphere will provide us with information concerning the degree of adaptation of certain physiological and biochemical functions and as to what extent biological readjustment or repair processes can occur under the specific stress conditions of space flight.

    2017-04-01

    To determine if the OOPS index is predictive of long-term hearing results after ossiculoplasty. Case series with retrospective chart review. Tertiary care otology practice. Adult and pediatric patients (3-88 years of age). Ossiculoplasty with cartilage tympanoplasty, with or without mastoidectomy. Primary outcome measures included short-term hearing results (pure-tone average air-bone gap [PTA-ABG] measured between 60 days and 1 year after surgery), long-term hearing results (PTA-ABG measured ≥5 years after surgery), and the rate of successful ABG closure to ≤20 dB. Secondary measures included the need for revision surgery, delayed tympanic membrane graft failure, worsening conductive hearing loss (after an initially satisfactory hearing result), and recurrence of cholesteatoma. There was no significant difference between adults and children for short-term hearing results (average post-op PTA-ABG was 18.9 dB vs. 19.8 dB, respectively; p = 0.544), long-term hearing results (average final PTA-ABG was 19.3 dB vs. 19.4 dB, respectively; p = 0.922), or rate of ABG closure to less than 20 dB (63.1% vs. 58.0%, p = 0.282). Spearman's rank-order correlation (ρ) identified a strong positive correlation between OOPS index score and average post-operative PTA-ABG (ρ = 0.983; p < 0.001; 2-tailed), as well as average long-term PTA-ABG (ρ = 0.950, p < 0.001; 2-tailed). The OOPS index makes it possible to accurately prognosticate hearing outcomes in adult and pediatric patients undergoing ossiculoplasty in both the short term and the long term.

    Purpose Proximal row carpectomy is a well-established technique for the management of wrist arthritis; however, patient selection and long-term durability of proximal row carpectomy is still a matter of controversy. Hence, we conducted a systematic review of the English literature to determine the best evidence on long-term outcomes following proximal row carpectomy. Methods A MEDLINE search using the term “proximal row carpectomy” was performed. A total of 192 studies were identified. All studies with 10 or more years of follow-up were included in the review. Data extracted included patient demographics, indications for surgery, previous surgery, outcome assessment, and information on complications and failures. Results A total of 147 patients from six studies met the inclusion criteria and were included in the study. The majority of patients were male and involved in manual labor. There was no significant difference between the preoperative and long-term postoperative motion. The weighted mean for postoperative grip strength was 68.4% compared with the contralateral side. Disabilities of the arm, shoulder, and hand; patient-rated wrist examination; and Mayo wrist scores were comparable to those reported for four-corner arthrodesis. There were 21 failures (14.3%) requiring re-operation. Failures were not associated with a specific preoperative diagnosis but distributed among patients with Kienböck disease, scaphoid nonunion advanced collapse, and scapholunate advanced collapse arthritis. Conclusions This systematic review confirms the long-term durability of proximal row carpectomy when used for the treatment of wrist arthritis. Although radiocapitate arthritis develops over time in most patients, the clinical significance of this finding is undetermined and does not necessarily correlate with failure of proximal row carpectomy. Poorer long-term outcomes are likely to result in patients engaged in heavy manual labor, whereas better outcomes may be

    The introduction of TNFα blockers has revolutionized the treatment of ankylosing spondylitis (AS). The objectives of this review are to summarize the most up-to-date data on long-term efficacy and safety of infliximab in AS, with special emphasis on axial and extra-articular disease, predictors of response, and radiological response. The general consensus of this literature search was that infliximab is highly efficacious in the treatment of AS. Most studies have demonstrated good clinical outcomes after 3 years of treatment, as measured by Spondyloarthritis International Society response in 75%–85% of treated AS patients. Reports on the long-term effects of infliximab as documented by radiological findings, however, are controversial. While some studies reported a similar progression rate as that of the historical OASIS cohort, others have suggested that infliximab may halt new bone formation. The long-term safety of infliximab is well known, mainly from data stored in national registries. While it has been suggested that side effects of infliximab may be fewer in AS compared to rheumatoid arthritis, data on this issue are sparse, with most of the information on long-term safety pertaining to rheumatoid arthritis. It can however be concluded that the long-term efficacy of infliximab is apparently maintained in AS and with an acceptable safety profile. PMID:26640380

    Glucksman, Myron L

    The long-term (14 years) psychodynamic psychotherapy and pharmacotherapy of a depressed, suicidal, self-mutilating female patient is described. Her diagnoses included Chronic Posttraumatic Stress Disorder, Borderline Personality Disorder, and Recurrent Major Depression. Treatment was punctuated with repeated hospitalizations for self-mutilation (cutting) and suicidal ideation. A major determinant for her psychopathology was sexual abuse by her father from ages 6 to 14. This resulted in feelings of guilt and rage that she repressed and acted out through self-mutilating and suicidal behavior. A prolonged negative transference gradually became ambivalent, then positive. This was associated with her internalization of the healing qualities of the therapeutic relationship. She also gained insight into the reasons for her need to punish herself. Her initial self-representation as unworthy and bad was transformed into perceiving herself as a worthwhile, loving person. This case illustrates the role of long-term treatment for a complex, life-threatening, psychiatric disorder.

    A model for the SSC arcs is described with multipole lattice field errors agglomerated into 32 lattice points, and with first order lattice errors and modulation provided by discrete transfer elements. Numerical solutions for long term dynamic aperture studies are obtained by multipole kick-drift tracking. The CPU time required to track through one turn is minimal, and comparable to that required to implement a one-turn fifth-order Taylor series map. Comparisons with tracking results using a fine grained representation of the lattice are made, and found to be satisfactory. The effects of tune modulation are studied and can substantially degrade long-term dynamic aperture. The effects of small relativistic momentum corrections, usually neglected for the large momenta at the SSC, are shown to have negligible influence on tracking results. 5 refs., 7 figs.

    The various forms of arthritis associated with a gonococcus infection are pathogenetically and clinically differentiated. Whereas an infectious systemic process with different clinical symptoms is said to be underlying the arthritis-dermatitis syndrome as well as the septic GO-arthritis, the third form is para-infectious reactive arthritis. It is often difficult to diagnose an infectious GO-arthritis, as direct evidence of the virus found in joint and blood is rarely positive, so that the diagnosis can be affirmed or negated on the basis of clinical facts of the reaction of arthritis after an appropriate antibiotic therapy. Differential diagnostic considerations may help to find the correct diagnosis in view of an acute urethritis arthritis.

    2013-01-01

    Abstract Objective To summarize the current evidence-based knowledge about the long-term sequelae of injuries from electrical current. Quality of evidence MEDLINE was searched for English-language articles published in the past 20 years using the following search terms: electrical, injuries, wound, trauma, accident, sequelae, long-term, follow-up, and aftereffects. For obvious reasons, it is unethical to randomly study electrical injury in controlled clinical trials. By necessity, this topic is addressed in less-rigorous observational and retrospective work and case studies. Therefore, the strength of the literature pertaining to the long-term sequelae of electrical injury is impaired by the necessity of retrospective methods and case studies that typically describe small cohorts. Main message There are 2 possible consequences of electrical injury: the person either survives or dies. For those who survive electrical injury, the immediate consequences are usually obvious and often require extensive medical intervention. The long-term sequelae of the electrical injury might be more subtle, pervasive, and less well defined, but can include neurologic, psychological, and physical symptoms. In the field of compensation medicine, determining causation and attributing outcome to an injury that might not result in objective clinical findings becomes a considerable challenge. Conclusion The appearance of these consequences of electrical injury might be substantially delayed, with onset 1 to 5 or more years after the electrical injury. This poses a problem for patients and health care workers, making it hard to ascribe symptoms to a remote injury when they might not arise until well after the incident event. PMID:24029506

    2015-01-01

    Opioid addiction is associated with excess mortality, morbidities, and other adverse conditions. Guided by a life-course framework, we review the literature on the long-term course of opioid addiction in terms of use trajectories, transitions, and turning points, as well as other factors that facilitate recovery from addiction. Most long-term follow-up studies are based on heroin addicts recruited from treatment settings (mostly methadone maintenance treatment), many of whom are referred by the criminal justice system. Cumulative evidence indicates that opioid addiction is a chronic disorder with frequent relapses. Longer treatment retention is associated with a greater likelihood of abstinence, whereas incarceration is negatively related to subsequent abstinence. Over the long term, the mortality rate of opioid addicts (overdose being the most common cause) is about 6 to 20 times greater than that of the general population; among those who remain alive, the prevalence of stable abstinence from opioid use is low (less than 30% after 10-30 years of observation), and many continue to use alcohol and other drugs after ceasing to use opioids. Histories of sexual or physical abuse and comorbid mental disorders are associated with the persistence of opioid use, whereas family and social support, as well as employment, facilitates recovery. Maintaining opioid abstinence for at least five years substantially increases the likelihood of future stable abstinence. Recent advances in pharmacological treatment options (buprenorphine and naltrexone) include depot formulations offering longer duration of medication; their impact on the long-term course of opioid addiction remains to be assessed.

    Objective: To evaluate predictors of long term prognosis in infective endocarditis. Design: Retrospective cohort study. Setting: Tertiary care centre. Patients: 212 consecutive patients with infective endocarditis between 1980 and 1995 Main outcome measures: Overall and cardiac mortality; event-free survival; and the following events: recurrence, need for late valve surgery, bleeding and embolic complications, cerebral dysfunction, congestive heart failure. Results: During a mean follow up period of 89 months (range 1–244 months), 56% of patients died. In 180 hospital survivors, overall and cardiac mortality amounted to 45% and 24%, respectively. By multivariate analysis, early surgical treatment, infection by streptococci, age < 55 years, absence of congestive heart failure, and > 6 symptoms or signs of endocarditis during active infection were predictive of improved overall long term survival. Independent determinants of event-free survival were infection by streptococci and age < 55 years. Event-free survival was 17% at the end of follow up both in medically–surgically treated patients and in medically treated patients. Conclusions: Long term survival following infective endocarditis is 50% after 10 years and is predicted by early surgical treatment, age < 55 years, lack of congestive heart failure, and the initial presence of more symptoms of endocarditis.

    2000-10-01

    We present here the results and interpretation of a long-term OH variability program conducted with the French {Nançay} Radiotelescope from 1980 to 1995. It concerns seven Mira stars: R Aql, RS Vir, S CrB, R LMi, RR Aql, U Her and UX Cyg. This study deals with the three OH maser lines observed in the Miras at 1612, 1665 and 1667 MHz. These OH variable stars have periods ranging from 290 to 580 days. The study presents the first insight of the long-term temporal behaviour of OH integrated flux variations as well as spectral component variations. The main aims are to determine the temporal behaviour of the OH maser emission and the longevity and variability of the spectral components. We find that the shapes of the OH curve are closer to the IR than the optical shapes and that the emissions at 1665 and 1667 MHz have a very similar behaviour while the emission at 1612 MHz behaves differently. The 1612 MHz emission shows smoother temporal variations and greater component longevity than the main line emission, leading to the conclusion that the 1612 MHz emission is coming from an outer part of the circumstellar shell and is more saturated than the main line emission. The study also shows the existence of inhomogeneities, especially differences between the front and back parts of the shell can be seen, and that OH variability curves undergo long term variations over several cycles.

    The emerging application of long-term and high-quality ECG recording requires alternative electrodes to improve the signal quality and recording capability of surface skin electrodes. The esophageal ECG has the potential to overcome these limitations but necessitates novel recorder and lead designs. The electrode material is of particular interest, since the material has to ensure conflicting requirements like excellent biopotential recording properties and inertness. To this end, novel electrode materials like PEDOT and silver-PDMS as well as established electrode materials such as stainless steel, platinum, gold, iridium oxide, titanium nitride, and glassy carbon were investigated by long-term electrochemical impedance spectroscopy and model-based signal analysis using the derived in vitro interfacial properties in conjunction with a dedicated ECG amplifier. The results of this novel approach show that titanium nitride and iridium oxide featuring microstructured surfaces did not degrade when exposed to artificial acidic saliva. These materials provide low electrode potential drifts and insignificant signal distortion superior to surface skin electrodes making them compatible with accepted standards for ambulatory ECG. They are superior to the noble and polarizable metals such as platinum, silver, and gold that induced more signal distortions and are superior to esophageal stainless steel electrodes that corrode in artificial saliva. The study provides rigorous criteria for the selection of electrode materials for prolonged ECG recording by combining long-term in vitro electrode material properties with ECG signal quality assessment.

    Bipolar disorder is a major cause of disability, and the prevention of relapse is a key management goal. Pharmacological interventions, effectively delivered through enhanced clinical care, are central to long-term management. This article summarises the available evidence for a range of pharmacological options, and provides guidance on common issues in clinical management in line with current practice guidelines. The use of medications for long-term prophylaxis should be considered in all patients meeting criteria for bipolar I disorder. Increasing high-quality evidence from randomised trials informs management decisions relating to both novel agents, such as lamotrigine and olanzapine, and longer-established therapies, such as lithium and valproate, in monotherapy. Medications taken long-term in bipolar disorder differ in the extent to which they protect against manic and depressive relapse. Consequently, the emerging challenge is to understand how combination treatments can enhance efficacy and effectiveness based on data from controlled trials rather than random polypharmacy. Clinical care can be enhanced with effective education about the illness, and the use of strategies to improve treatment adherence and the recognition and management of stressors or prodromal symptoms. Where available, a range of specific psychological interventions can be effective as an adjunct to medication. When discontinuation of prophylaxis is necessary, gradual tapering of dose over weeks or months is recommended.

  7. Long term therapy of generalized anxiety disorder.

    Rouillon, Frédéric

    2004-04-01

    Generalized anxiety disorder (GAD) is a common (lifetime prevalence: 5.1%), recurrent condition, which often heralds other psychiatric disorders, notably depression. As by definition it is a disorder progressing over months, treatment should be designed on a long term basis. And yet, few studies have been conducted beyond the classical 6-8 weeks characterizing the acute treatment phase. This is especially true of anxiolytics, but also of antidepressants, with the exception of paroxetine and venlafaxine, which are the only drugs approved in this indication in Western countries. The efficacy of psychotherapy, notably relaxation and cognitive-behavioral therapy, is established in the treatment of GAD, but its preferred indications and possible combination with antidepressants are still to be specified. Long term, not to say very long term studies of GAD, as well as depression, will still be required in the future to improve its management and specify therapeutic modalities (combination treatment, optimal duration, continuous or intermittent therapy, choice of psychotherapeutic techniques or agents, em leader ). Early and adequately prolonged treatment should not only result in more numerous remission periods, but also in decreased frequency of co-morbidities whether depressive, addictive, or of another nature, and should also reduce the social impact of GAD.

  8. Titanium for long-term tritium storage

    Due to the reduction of nuclear weapon stockpile, there will be an excess of tritium returned from the field. The excess tritium needs to be stored for future use, which might be several years away. A safe and cost effective means for long term storage of tritium is needed. Storing tritium in a solid metal tritide is preferred to storing tritium as a gas, because a metal tritide can store tritium in a compact form and the stored tritium will not be released until heat is applied to increase its temperature to several hundred degrees centigrade. Storing tritium as a tritide is safer and more cost effective than as a gas. Several candidate metal hydride materials have been evaluated for long term tritium storage. They include uranium, La-Ni-Al alloys, zirconium and titanium. The criteria used include material cost, radioactivity, stability to air, storage capacity, storage pressure, loading and unloading conditions, and helium retention. Titanium has the best combination of properties and is recommended for long term tritium storage.

    Fifty-six patients with rheumatoid arthritis were treated continuously with cortisone for periods ranging between 4 and 38 months, in daily doses of 15 to 100 mg. Concomitant therapy included periods of rest, physical therapy, and salicylates. The incidence of subjective improvement exceeded that of objective improvement. The incidence of objective improvement was higher in females; also, in those patients whose disease was in an early stage and of short duration at the time therapy was begun, and who required relatively smaller maintenance doses of cortisone. Therapeutic results were not affected by the age of the patient or by the presence of spondylitis. Despite precautions, the long-term administration of cortisone was, in some patients, productive of serious undesirable side-effects. Although cortisone usually suppressed the symptoms and signs of rheumatoid arthritis, progression of the disease was frequently noted during its long-term administration.

    To determine alternate therapeutic measures to combat Staphylococcus aureus induced arthritis. Thus, azithromycin was combined with riboflavin, which may combat the ROS production and inflammation. An in vivo model of S. aureus infection-induced arthritis was set up by infecting mice with 5 × 10⁶ bacterial cell/mouse. S. aureus was administered intravenously. Azithromycin and riboflavin was injected intraperitoneally at a single dose of 100 and 20 mg/kg body, respectively. The mice were sacrificed at 3, 9, 15 days post infection (dpi). TNF-α, IFN-γ, IL-6 and IL-10 from serum and SOD, catalase and reduced glutathione concentration were observed in hepatic, cardiac, renal and splenic tissue. CFU was found very prominent in spleen and joints and reduced in blood at 3 and 9 dpi. However, treatment with azithromycin and riboflavin completely eradicated the bacteria from blood and spleen. TNF-α, IFN-γ, IL-6, and MCP-1 were induced due to infection which were downregulated by treatment with azithromycin and riboflavin. Infected mice were also found to have altered antioxidant status, measured in terms of reduced glutathione and anti-oxidant enzymes such as SOD and catalase. These changes were found to be ameliorated when the animals were co-treated with azithromycin and riboflavin.

  11. Timber beams subjected to long - term loading

    Wood is a significant structural material, which is often used for timber bearing structures. Elements of timber structures must especially satisfy safety requirements, which are expressed by the ultimate limit states in the established standards. The structure must also satisfy the serviceability limit states. Local and global deformations make it impossible for the structure to serve the purpose it was designed for. It is important to take the deflections and their possible increase into account in the design to provide a structure which can be used during the whole period of service. Based on earlier examinations, it is known that a timber element over the course of long-term loading shows creep behavior. The structure of wood is able to adapt to the conditions of the surrounding environment. The properties of wood are especially affected by the relative humidity of the air and then by the type, intensity and duration of the loading. The most important factors affecting the serviceability of timber structures are volume changes caused by humidity and additional deflections caused by the effects of long-term loading. These phenomena emphasize the importance of serviceability limit states for timber structures. The paper deals with a long-term experimental investigation of timber girders that are currently often used. The aim was to obtain the deflection curves and mark the time dependence and the final deflections. The paper will also define the approximations for simulating the time-dependent deflections and obtain the creep coefficients for calculating the final deflections of the girders investigated.

    Amnesia is usually described as an impairment of a long-term memory (LTM) despite an intact short-term memory (STM). The intact recency effect in amnesia had supported this view. Although dual-store models of memory have been challenged by single-store models based on interference theory, this had relatively little influence on our understanding and treatment of amnesia, perhaps because the debate has centred on experiments in the neurologically intact population. Here we tested a key prediction of single-store models for free recall in amnesia: that people with amnesia will exhibit a memory advantage for the most recent items even when all items are stored in and retrieved from LTM, an effect called long-term recency. People with amnesia and matched controls studied, and then free-recalled, word lists with a distractor task following each word, including the last (continual distractor task, CDFR). This condition was compared to an Immediate Free Recall (IFR, no distractors) and a Delayed Free Recall (DFR, end-of-list distractor only) condition. People with amnesia demonstrated the full long-term recency pattern: the recency effect was attenuated in DFR and returned in CDFR. The advantage of recency over midlist items in CDFR was comparable to that of controls, confirming a key prediction of single-store models. Memory deficits appeared only after the first word recalled in each list, suggesting the impairment in amnesia may emerge only as the participant’s recall sequence develops, perhaps due to increased susceptibility to output interference. Our findings suggest that interference mechanisms are preserved in amnesia despite the overall impairment to LTM, and challenge strict dual-store models of memory and their dominance in explaining amnesia. We discuss the implication of our findings for rehabilitation. PMID:26046770

    Prolactinomas are a frequent cause of gonadal dysfunction and infertility, especially in young women. The regulation of prolactin secretion and the efficacy of dopamine agonists in the therapy of prolactinomas are well established. The current challenges in management of prolactinomas are related to follow-up after successful therapy. Issues and questions to be addressed in this approach to long-term management of prolactinomas include the frequency of radiographic monitoring, effect of pregnancy and menopause, safety of estrogen in women taking oral contraceptives, and the potential for discontinuation of dopamine agonist therapy.

    The National Renewable Energy Laboratory started collecting wind power data from large commercial wind power plants (WPPs) in southwest Minnesota with dedicated dataloggers and communication links in the spring of 2000. Over the years, additional WPPs in other areas were added to and removed from the data collection effort. The longest data stream of actual wind plant output is more than 10 years. The resulting data have been used to analyze wind power fluctuations, frequency distribution of changes, the effects of spatial diversity, and wind power ancillary services. This report uses the multi-year wind power data to examine long-term wind power variability.

    This article emphasizes the critical importance of the skeletal differential between the width of the maxilla and the width of the mandible. Undiagnosed transverse discrepancy leads to adverse periodontal response, unstable dental camouflage, and less than optimal dentofacial esthetics. Hundreds of adult retreatment patients corrected for significant maxillary transverse deficiency using surgically assisted maxillary expansion (similar to osseous distraction) has produced excellent stability. Eliciting tooth movement for children (orthopedics, lip bumper, Cetlin plate) in all three planes of space by muscles, eruption, and growth, develops the broader arch form (without the mechanical forces of fixed or removable appliances) and has also demonstrated impressive long term stability.

    Long-term trials often include more than one active treatment group. These may be discontinued independently if found ineffective or possibly harmful. Certain subgroups of patients may be discovered, in the course of a clinical trial, who do not respond satisfactorily and are, therefore, excluded during the course of a trial. Yet anouther kind of termination comes when we have a therapeutic breakthrough or when hope has to be abandoned for demonstrating beneficial effects for one, several, or all treatments included in a trial. Examples from the authors' experience are presented, as are successful and unsuccessful techniques in managing terminations of various types.

    Medicanes, intense and destructive mesoscale cyclones exhibiting several similarities with tropical hurricanes, are known to struck occasionally the Mediterranean Sea. Thanks to a high-resolution dynamical downscaling effort, we are able to study for the first time the long-term climatology of those rare storms in a systematic way. The distribution of medicanes frequency in space and time is discussed, and the environmental factors responsible for their formation are investigated. We find that medicanes develop in those areas of the Mediterranean region where intrusions of cold air in the upper troposphere can produce configurations of thermodynamical disequilibrium of the atmosphere similar to those associated with the formation of tropical cyclones.

    OBJECTIVE—The purpose of this study was to compare the long term effectiveness between chloroquine (CQ) and hydroxychloroquine (HCQ).
METHODS—Medical charts of all patients seen by eight rheumatologists practising in two tertiary care centres and starting antimalarial treatment between January 1985 and December 1993 were reviewed. Patient characteristics, disease, and treatment information were collected. The main outcome measures were the cause of and the time to the discontinuation of antimalarial drugs resulting from all causes, principally toxicity or inefficacy, or both. Bivariate analysis including t tests and χ2 tests were used to assess differences between means and proportions respectively. Survival curves were evaluated using the Kaplan-Meier method. Multivariate analysis (Cox regression) was used to adjust for potential confounders.
RESULTS—After all medical records were reviewed, 1042 eligible cases were identified. From these, 940 (90%) had usable information and they represent the cohort. Five hundred and fifty eight had rheumatoid arthritis, 178 had systemic lupus erythematosus, 127 had palindromic arthritis, and 77 had other diagnoses. Fifty seven per cent of the patients received CQ and 43% HCQ. The proportion of patients with side effects taking HCQ and CQ was 15% and 28% respectively (p=0.001). Using Cox regression model to adjust for age at the onset of antimalarial treatment, physician differences, sex, disease type, disease duration before treatment, and rank selection, there were no differences in the hazard ratio (HR) for overall discontinuations between CQ and HCQ. While the HR for discontinuations because of toxicity was lower for HCQ (HR= 0.6, 95% CI 0.4, 0.9), the HR for discontinuations because of inefficacy was significantly higher for HCQ (HR= 1.4, 95% CI 1.1, 1.9).
CONCLUSIONS—After adjusting for time and several confounders HCQ was less toxic but less effective than CQ. Only one case of probable

  3. Septic and non-septic olecranon bursitis in the accident and emergency department--an approach to management.

    Olecranon bursitis is relatively common. One third of episodes are septic. Most of the remainder are non-septic, with occasional rheumatological causes. Trauma can cause both septic and non-septic olecranon bursitis. Clinical features are helpful in separating septic from non-septic olecranon bursitis, but there may be local erythema in both. Aspiration should be carried out in all cases, and if the presence of infection is still in doubt, microscopy, Gram staining, and culture of the aspirate will resolve the issue. Septic olecranon bursitis should be treated by aspiration, which may need to be repeated, and a long course of antibiotics. Some cases will need admission, and a few will need surgical treatment. Non-septic olecranon bursitis can be managed with aspiration alone. Non-steroidal anti-inflammatory drugs probably hasten symptomatic improvement. Intrabursal corticosteroids produce a rapid resolution but concern remains over their long term local effects. Recovery from septic olecranon bursitis can take months. PMID:8894865

    The acute phase of chikungunya is well documented; less so are its long-term effects. This systematic literature review provides an overview of the currently available data. We performed an electronic search in PubMed/Medline and checked reference lists. We included studies in English on long-term sequelae of chikungunya in adults and on long-term sequelae of congenital infection from 2000 to 2016. Case reports, reviews and studies with a follow-up shorter than 6 weeks were excluded. In total, 37 studies were included; with follow-up periods ranging from 1.5 to 72 months. Most studies were questionnaire-based studies only, in which clinical diagnoses such as arthritis, alopecia and depression were mostly recorded without professional verification. Persisting arthralgia/arthritis (arthralgia/joint stiffness plus joint swelling) was the most frequent problem encountered. Further frequently mentioned sequelae were alopecia and depression. Quality of life was reduced in many for months to years after the acute phase of chikungunya. Female gender, older age, some co-morbidities and the severity of the acute phase were associated with persistent arthralgia. Congenital infection was associated with neurocognitive dysfunctioning in early childhood. Chikungunya leads to (self-perceived) long-term sequelae in a considerable proportion of patients, impacting significantly on quality of life. Long-term chikungunya sequelae must be taken into account when dealing with this disease because of its important effect on public and individual health. Prospective large-scale, long-term studies with objective assessment of signs and symptoms attributed to the disease are needed to optimally quantify and qualify these problems.

    Singapore, like many developed countries, is facing the challenge of a rapidly aging population and the increasing need to provide long-term care (LTC) services for elderly in the community. The Singapore government's philosophy on care for the elderly is that the family should be the first line of support, and it has relied on voluntary welfare organizations (VWOs) or charities for the bulk of LTC service provision. For LTC financing, it has emphasized the principles of co-payment and targeting of state support to the low-income population through means-tested government subsidies. It has also instituted ElderShield, a national severe disability insurance scheme. This paper discusses some of the challenges facing LTC policy in Singapore, particularly the presence of perverse financial incentives for hospitalization, the pitfalls of over-reliance on VWOs, and the challenges facing informal family caregivers. It discusses the role of private LTC insurance in LTC financing, bearing in mind demand- and supply-side failures that have plagued the private LTC insurance market. It suggests the need for more standardized needs assessment and portable LTC benefits, with reference to the Japanese Long-Term Care Insurance program, and also discusses the need to provide more support to informal family caregivers.

    Adaptation is an automatic neural mechanism supporting the optimization of visual processing on the basis of previous experiences. While the short-term effects of adaptation on behaviour and physiology have been studied extensively, perceptual long-term changes associated with adaptation are still poorly understood. Here, we show that the integration of adaptation-dependent long-term shifts in neural function is facilitated by sleep. Perceptual shifts induced by adaptation to a distorted image of a famous person were larger in a group of participants who had slept (experiment 1) or merely napped for 90 min (experiment 2) during the interval between adaptation and test compared with controls who stayed awake. Participants' individual rapid eye movement sleep duration predicted the size of post-sleep behavioural adaptation effects. Our data suggest that sleep prevented decay of adaptation in a way that is qualitatively different from the effects of reduced visual interference known as ‘storage’. In the light of the well-established link between sleep and memory consolidation, our findings link the perceptual mechanisms of sensory adaptation—which are usually not considered to play a relevant role in mnemonic processes—with learning and memory, and at the same time reveal a new function of sleep in cognition.

    The survival rate for childhood craniopharyngioma has been improving, with more long-term survivors. Unfortunately it is rare for the patient to be normal, either from the disease itself or from the effects of treatment. Long-term survivors of childhood craniopharyngioma suffer a number of impairments, which include visual loss, endocrinopathy, hypothalamic dysfunction, cerebrovascular problems, neurologic and neurocognitive dysfunction. Pituitary insufficiency is present in almost 100%. Visual and hypothalamic dysfunction is common. There is a high risk of metabolic syndrome and increased risk of cerebrovascular disease, including stroke and Moyamoya syndrome. Cognitive, psychosocial, and emotional problems are prevalent. Finally, there is a higher risk of premature death among survivors of craniopharyngioma, and often this is not from tumor recurrence. It is important to consider craniopharyngioma as a chronic disease. There is no perfect treatment. The treatment has to be tailored to the individual patient to minimize dysfunction caused by tumor and treatments. So “cure” of the tumor does not mean a normal patient. The management of the patient and family needs multidisciplinary evaluation and should involve ophthalmology, endocrinology, neurosurgery, oncology, and psychology. Furthermore, it is also important to address emotional issues and social integration. PMID:26345668

    Using the Hilbert-Huang Transform method, we investigate the long-term trend of yearly mean total sunspot numbers in the time interval of 1700-2015, which come from the World Data Center—the sunspot Index and long-term solar observations. The main findings of this study are summarized below. (1) From the adaptive trend, which is extracted from the yearly mean total sunspot numbers, we can find that the value gradually increases during the time period 1700-1975, then decreases gradually from 1975 to 2015. (2) The Centennial Gleissberg Cycle is extracted from the yearly mean total sunspot numbers and confirms that a new grand minimum is in progress; the Dalton Minimum, the Gleissberg Minimum, and low level of solar activity during solar cycle 24 (the part of the new grand minimum) all can be understood as minima of the Centennial Gleissberg Cycle. (3) Based on the adaptive (overall) trend, and the 100-year and longer timescale trend of yearly mean total sunspot numbers, we can infer that the level of solar activity during the new grand minimum may be close to that during the Gleissberg Minimum, slightly higher than that during the Dalton Minimum, and significantly higher than that during the Maunder Minimum. Our results do not support the suggestion that a new grand minimum, somewhat resembling the Maunder Minimum, is in progress.

  10. Clinical review: Long-term noninvasive ventilation

    2007-01-01

    Noninvasive positive ventilation has undergone a remarkable evolution over the past decades and is assuming an important role in the management of both acute and chronic respiratory failure. Long-term ventilatory support should be considered a standard of care to treat selected patients following an intensive care unit (ICU) stay. In this setting, appropriate use of noninvasive ventilation can be expected to improve patient outcomes, reduce ICU admission, enhance patient comfort, and increase the efficiency of health care resource utilization. Current literature indicates that noninvasive ventilation improves and stabilizes the clinical course of many patients with chronic ventilatory failure. Noninvasive ventilation also permits long-term mechanical ventilation to be an acceptable option for patients who otherwise would not have been treated if tracheostomy were the only alternative. Nevertheless, these results appear to be better in patients with neuromuscular/-parietal disorders than in chronic obstructive pulmonary disease. This clinical review will address the use of noninvasive ventilation (not including continuous positive airway pressure) mainly in diseases responsible for chronic hypoventilation (that is, restrictive disorders, including neuromuscular disease and lung disease) and incidentally in others such as obstructive sleep apnea or problems of central drive.

    As the amount of halogens in the stratosphere is slowly declining and the ozone layer slowly recovers it is of interest to see how the meteorological conditions in the vortex develop over the long term since such changes might alter the foreseen ozone recovery. In conjunction with the publication of the WMO Antarctic and Arctic Ozone Bulletins, WMO has acquired the ERA Interim global reanalysis data set for several meteorological parameters. This data set goes from 1979 - present. These long time series of data can be used for several useful studies of the long term development of the polar vortices. Several "environmental indicators" for vortex change have been calculated, and a climatology, as well as trends, for these parameters will be presented. These indicators can act as yardsticks and will be useful for understanding past and future changes in the polar vortices and how these changes affect polar ozone depletion. Examples of indicators are: vortex mean temperature, vortex minimum temperature, vortex mean PV, vortex "importance" (PV*area), vortex break-up time, mean and maximum wind speed. Data for both the north and south polar vortices have been analysed at several isentropic levels from 350 to 850 K. A possible link between changes in PV and sudden stratospheric warmings will be investigated, and the results presented.

    Caspian Sea level (CSL) has undergone substantial fluctuations during the past several hundred years. The causes over the entire historical period are uncertain, but we investigate here large changes seen in the past several decades. We use climate model-predicted precipitation (P), evaporation (E), and observed river runoff (R) to reconstruct long-term CSL changes for 1979-2015 and show that PER (P-E + R) flux predictions agree very well with observed CSL changes. The observed rapid CSL increase (about 12.74 cm/yr) and significant drop ( -6.72 cm/yr) during the periods 1979-1995 and 1996-2015 are well accounted for by integrated PER flux predictions of +12.38 and -6.79 cm/yr, respectively. We show that increased evaporation rates over the Caspian Sea play a dominant role in reversing the increasing trend in CSL during the past 37 years. The current long-term decline in CSL is expected to continue into the foreseeable future, under global warming scenarios.

    We assessed the long term efficacy of Novopen as a form of insulin administration. Records were obtained on 48 patients who were treated with Novopen between January '86 and October '88. Six patients were excluded due to insufficient data. The study group of 42 patients comprised 22 females and 20 males of average age 33 years (range 17-66). Mean Hb.A1 rose from 10.6% to 12.1% after Novopen therapy, a rise of 14.1%. This rise is both clinically and statistically significant (p less than 0.001; 99% confidence limits 0.59-2.78). Increases in weight and insulin dose were also noted, but did not reach statistical significance. The majority of patients felt Novopen was superior to twice daily insulin in terms of ease of administration (81%) and flexibility of lifestyle (95%), and all who were using Novopen wished to continue with it. More than 50% of patients admitted to altering their dietary habits while using Novopen. Despite continuing patient satisfaction with this form of insulin administration, its long-term use may be associated with sub-optimal metabolic control.

    The benefit of climate Long Term Memory (LTM) for long term prediction is assessed using data from a millennium control simulation with the atmosphere ocean general circulation model ECHAM5/MPIOM. The forecast skills are evaluated for surface temperature time series at individual grid points. LTM is characterised by the Hurst exponent in the power-law scaling of the fluctuation function which is determined by detrended fluctuation analysis (DFA). LTM with a Hurst exponent close to 0.9 occurs mainly in high latitude oceans, which are also characterized by high potential predictability. Climate predictability is diagnosed in terms of potentially predictable variance fractions. Explicit prediction experiments for various time steps are conducted on a grid point basis using an auto-correlation (AR1) predictor: in regions with LTM, prediction skills are beyond that expected from red noise persistence; exceptions occur in some areas in the southern oceans and over the northern hemisphere continents. Extending the predictability analysis to the fully forced simulation shows large improvement in prediction skills.

    For many decades comparative analyses of protein sequences and structures have been used to investigate fundamental principles of molecular evolution. In contrast, relatively little is known about the long-term evolution of species' phenotypic and genetic properties. This represents an important gap in our understanding of evolution, as exactly these proprieties play key roles in natural selection and adaptation to diverse environments. Here we perform a comparative analysis of bacterial growth and gene deletion phenotypes using hundreds of genome-scale metabolic models. Overall, bacterial phenotypic evolution can be described by a two-stage process with a rapid initial phenotypic diversification followed by a slow long-term exponential divergence. The observed average divergence trend, with approximately similar fractions of phenotypic properties changing per unit time, continues for billions of years. We experimentally confirm the predicted divergence trend using the phenotypic profiles of 40 diverse bacterial species across more than 60 growth conditions. Our analysis suggests that, at long evolutionary distances, gene essentiality is significantly more conserved than the ability to utilize different nutrients, while synthetic lethality is significantly less conserved. We also find that although a rapid phenotypic evolution is sometimes observed within the same species, a transition from high to low phenotypic similarity occurs primarily at the genus level.

    Adipose tissue engineered models are needed to enhance our understanding of disease mechanisms and for soft tissue regenerative strategies. Perfusion systems generate more physiologically relevant and sustainable adipose tissue models, however adipocytes have unique properties that make culturing them in a perfusion environment challenging. In this paper we describe the methods involved in the development of two perfusion culture systems (2D and 3D) to test their applicability for long term in vitro adipogenic cultures. It was hypothesized that a silk protein biomaterial scaffold would provide a 3D framework, in combination with perfusion flow, to generate a more physiologically relevant sustainable adipose tissue engineered model than 2D cell culture. Consistent with other studies evaluating 2D and 3D culture systems for adipogenesis we found that both systems successfully model adipogensis, however 3D culture systems were more robust, providing the mechanical structure required to contain the large, fragile adipocytes that were lost in 2D perfused culture systems. 3D perfusion also stimulated greater lipogenesis and lipolysis and resulted in decreased secretion of LDH compared to 2D perfusion. Regardless of culture configuration (2D or 3D) greater glycerol was secreted with the increased nutritional supply provided by perfusion of fresh media. These results are promising for adipose tissue engineering applications including long term cultures for studying disease mechanisms and regenerative approaches, where both acute (days to weeks) and chronic (weeks to months) cultivation are critical for useful insight.

    Indapamide, 2.5 mg administered once daily for periods up to 36 months, was found to be safe and effective for the long-term control of mild to moderate hypertension. The effects of hydrochlorothiazide, 50 mg, and indapamide, 2.5 mg, were studied in two randomized, double-blind, multicenter trials. Data from the two multicenter trials (20 study sites) were pooled for purposes of comparison. Significant reductions in systolic and diastolic blood pressure, with patients in both supine and standing positions, occurred in both groups within the first 8 weeks of treatment. This effect was maintained throughout the active treatment period. Success, as determined by the therapeutic success rate (percentage of patients with decreases of standing phase V diastolic blood pressure of at least 10 mm Hg or to below 90 mm Hg), occurred in 53% of the patients given hydrochlorothiazide and in 56% of the indapamide-treated patients. During the study period, the nature, frequency, and severity of adverse reactions were similar for both groups. There was no clinically significant difference between the treatment groups for the laboratory assessments. Patients who completed the multicenter trials were eligible for participation in an ongoing long-term extension study of the safety of indapamide. Data are available for periods up to 36 months and demonstrate neither augmentation of clinical or laboratory adverse effects nor any potentially harmful indicators that could be attributed to prolonged treatment.

    As the amount of halogens in the stratosphere is slowly declining and the ozone layer slowly recovers it is of interest to see how the meteorological conditions in the vortex develop over the long term since such changes might alter the foreseen ozone recovery. In conjunction with the publication of the WMO Antarctic and Arctic Ozone Bulletins, WMO has acquired the ERA Interim global reanalysis data set for several meteorological parameters. This data set goes from 1979 - present. These long time series of data can be used for several useful studies of the long term development of the polar vortices. Several "environmental indicators" for vortex change have been calculated, and a climatology, as well as trends, for these parameters will be presented. These indicators can act as yardsticks and will be useful for understanding past and future changes in the polar vortices and how these changes affect polar ozone depletion. Examples of indicators are: vortex mean temperature, vortex minimum temperature, vortex mean PV, vortex "importance" (PV*area), vortex break-up time, mean and maximum wind speed. Data for both the north and south polar vortices have been analysed at several isentropic levels from 350 to 850 K. A possible link between changes in PV and sudden stratospheric warmings will be investigated, and the results presented. The unusual meteorological conditions of the 2015 south polar vortex and the 2010/11 and 2015/16 north polar vortices will be compared to other recent years.

    Escherichia coli is one of the most frequently diagnosed causes of bovine mastitis, and is typically associated with acute, clinical mastitis. The objective of the present study was to evaluate the long term effects of intramammary infections by E. coli on milk yield and quality, especially milk coagulation. Twenty-four Israeli Holstein cows diagnosed with clinical mastitis due to intramammary infection by E. coli were used in this study. Mean lactation number, days in milk (DIM) and daily milk yield (DMY) at the time of infection was 3.3 ± 1.3, 131.7 days ± 78.6 and 45.7 L ± 8.4, respectively. DMY, milk constituents, somatic cells count (SCC), differential leukocytes count and coagulation parameters were subsequently assessed. Two patterns of inflammation were identified: 'short inflammation', characterized by <15% decrease in DMY and <30 days until return to normal (n = 5), and 'long inflammation', characterized by >15% decrease in DMY and >30 days to reach a new maximum DMY (n = 19). The estimated mean loss of marketable milk during the study was 200 L/cow for 'short inflammation' cases, and 1,500 L/cow for 'long inflammation' ones. Significant differences between 'short' and 'long inflammation' effects were found in almost all parameters studied. Long-term detrimental effects on milk quality were found regardless of clinical or bacteriological cure of affected glands.

    We conducted a retrospective study comparing the presenting clinical and biologic features of 64 children who had septic arthritis caused by Kingella kingae with 26 children who had septic arthritis caused by Staphylococcus aureus. Children with K. kingae septic arthritis were significantly younger than those with S. aureus septic arthritis. Otherwise, there were no significant differences between the 2 groups with respect to fever, location, white blood cell count, synovial fluid cell count, C-reactive protein, or serum fibrinogen. However, the clinical course was significantly better for children with septic arthritis caused by K. kingae as evidenced by shorter hospitalization and fewer adverse events. Presumptive antibiotic therapy for septic arthritis in young infants should take into account both of these pathogens, even in case of mild presentation.

    Bacteria, viruses, fungi, and parasites can all cause arthritis of either acute or chronic nature, which can be divided into infective/septic, reactive, or inflammatory. Considerable advances have occurred in diagnostic techniques in the recent decades resulting in better treatment outcomes in patients with infective arthritis. Detection of emerging arthritogenic viruses has changed the epidemiology of infection-related arthritis. The role of viruses in the pathogenesis of chronic inflammatory arthritides such as rheumatoid arthritis is increasingly being recognized. We discuss the various causative agents of infective arthritis and emphasize on the approach to each type of arthritis, highlighting the diagnostic tests, along with their statistical accuracy. Various investigations including newer methods such as nucleic acid amplification using polymerase chain reaction are discussed along with the pitfalls in interpreting the tests.

    Sepsis occurs when an infection exceeds local tissue containment and induces a series of dysregulated physiologic responses that result in organ dysfunction. A subset of patients with sepsis progress to septic shock, defined by profound circulatory, cellular, and metabolic abnormalities, and associated with a greater mortality. Historically, sepsis-induced organ dysfunction and lethality were attributed to the complex interplay between the initial inflammatory and later anti-inflammatory responses. With advances in intensive care medicine and goal-directed interventions, early 30-day sepsis mortality has diminished, only to steadily escalate long after "recovery" from acute events. As so many sepsis survivors succumb later to persistent, recurrent, nosocomial, and secondary infections, many investigators have turned their attention to the long-term sepsis-induced alterations in cellular immune function. Sepsis clearly alters the innate and adaptive immune responses for sustained periods of time after clinical recovery, with immune suppression, chronic inflammation, and persistence of bacterial representing such alterations. Understanding that sepsis-associated immune cell defects correlate with long-term mortality, more investigations have centered on the potential for immune modulatory therapy to improve long-term patient outcomes. These efforts are focused on more clearly defining and effectively reversing the persistent immune cell dysfunction associated with long-term sepsis mortality.

    Disseminated gonococcal infection is the most common systemic complication of acute gonorrhea and occurs in 0.5% to 3.0% of patients with untreated mucosal infection. It is also the most common cause of septic arthritis in patients less than 30 years of age. Fortunately, the incidence of gonorrhea is decreasing dramatically in the United States and Western Europe, although it is still high in developing countries. Increasing resistance to antibiotics requires continuous surveillance of antimicrobial susceptibilities to determine the efficacy of current therapeutic measures.

  4. Managing soils for long-term productivity

    PubMed Central

    1997-01-01

    Meeting the goal of long-term agricultural productivity requires that soil degradation be halted and reversed. Soil fertility decline is a key factor in soil degradation and is probably the major cause of declining crop yields. There is evidence that the contribution of declining soil fertility to soil degradation has been underestimated.
    Sensitivity to soil degradation is implicit in the assessment of the sustainability of land management practices, with wide recognition of the fact that soils vary in their ability to resist change and recover subsequent to stress. The concept of resilience in relation to sustainability requires further elaboration and evaluation.
    In the context of soil degradation, a decline in soil fertility is primarily interpreted as the depletion of organic matter and plant nutrients. Despite a higher turnover rate of organic matter in the tropics there is no intrinsic difference between the organic matter content of soils from tropical and temperate regions. The level of organic matter in a soil is closely related to the above and below ground inputs. In the absence of adequate organic material inputs and where cultivation is continuous, soil organic matter declines progressively. Maintaining the quantity and quality of soil organic matter should be a guiding principle in developing management practices.
    Soil microbial biomass serves as an important reservoir of nitrogen (N), phosphorus (P) and sulphur (S), and regulates the cycling of organic matter and nutrients. Because of its high turnover rate, microbial biomass reacts quickly to changes in management and is a sensitive indicator for monitoring and predicting changes in soil organic matter. Modelling techniques have been reasonably successful in predicting changes in soil organic matter with different organic material inputs, but there is little information from the tropics.

    Tuberculous arthritis of the elbow joint is rare. A 57-year-old male patient presented with swelling, pain, and redness of the elbow. The symptoms first appeared one month ago; he was given antibiotic treatment after the diagnosis of septic arthritis at another center. The patient who did not improve with treatment was diagnosed with tuberculous arthritis according to the culture and was started on antituberculosis treatment. Tuberculous arthritis usually presents with chronic arthritis. However, it can also present in patients with septic arthritis.

    Several tests and methods for the investigation of neurotoxicity were performed with female Wistar rats for up to 187 days. The methods were validated by testing 10 rats treated with beta,beta'-iminodipropionitrile (IDPN) and 10 control rats. Cage side observation of the animals revealed signs of altered behavior and motor dysfunction of the IDPN-treated rats. Results of a neuromuscular screen indicated changes in gait, righting reflex, grip strength and performance of the negative geotropism test. Investigation of the animals in activity monitors and on the accelerating rotarod showed changes of several parameters. The motor nerve conduction velocity, measured 6 months after the first treatment, was reduced by 6.7 meters per second in the IDPN group compared to controls. From the results of the tests it can be concluded that the methods chosen can be used during long-term studies but may be most useful for animals not older than 12 months.

    Reservoir performance is one of the key issues that have to be addressed before going ahead with the development of a geothermal field. In order to select the type and size of the power plant and design other surface installations, it is necessary to know the characteristics of the production wells and of the produced fluids, and to predict the changes over a 10--30 year period. This is not a straightforward task, as in most cases the calculations have to be made on the basis of data collected before significant fluid volumes have been extracted from the reservoir. The paper describes the methodology used in predicting the long-term performance of hydrothermal systems, as well as DOE/GTD-sponsored research aimed at reducing the uncertainties associated with these predictions. 27 refs., 1 fig.

    A procedure is presented for planning and implementing a long-term environmental monitoring program for closed low-level radioactive waste disposal sites. The initial task in this procedure is to collect the available information on the legal/regulatory requirements, site and area characteristics, source term, pathway analysis, and prior monitoring results. This information is coupled with parameters such as half-life and retardation factors to develop a monitoring program. As examples, programs are presented for a site that has had little or no waste migration, and for sites where waste has been moved by suface water, by ground water, and by air. Sampling techniques and practices are discussed relative to how a current program would be structured and projections are made on techniques and practices expected to be available in the future. 8 refs., 2 figs.

    In exploring the emotional climate of long-term marriages, this study used an observational coding system to identify specific emotional behaviors expressed by middle-aged and older spouses during discussions of a marital problem. One hundred and fifty-six couples differing in age and marital satisfaction were studied. Emotional behaviors expressed by couples differed as a function of age, gender, and marital satisfaction. In older couples, the resolution of conflict was less emotionally negative and more affectionate than in middle-aged marriages. Differences between husbands and wives and between happy and unhappy marriages were also found. Wives were more affectively negative than husbands, whereas husbands were more defensive than wives, and unhappy marriages involved greater exchange of negative affect than happy marriages.

Particular emphasis is placed on Scenario B, which is the mid-range reference case. As the introduction to the supplement emphasizes, the NEPP projections should not be considered a statement of the policy goals of the Reagan Administration. They represent an analysis of the possible evolution of U.S. energy markets, given current information and existing policies. The purpose of providing Scenario B as a reference case as well as Scenarios A and C as alternate cases is to show the sensitivity of oil price projections to small swings in energy demand.

    Long term, cryogenic fluid storage facilities will be required to support future space programs such as the space-based Orbital Transfer Vehicle (OTV), Telescopes, and Laser Systems. An orbital liquid oxygen/liquid hydrogen storage system with an initial capacity of approximately 200,000 lb will be required. The storage facility tank design must have the capability of fluid acquisition in microgravity and limit cryogen boiloff due to environmental heating. Cryogenic boiloff management features, minimizing Earth-to-orbit transportation costs, will include advanced thick multilayer insulation/integrated vapor cooled shield concepts, low conductance support structures, and refrigeration/reliquefaction systems.

    Researchers installed radon mitigation systems in 12 houses in Spokane, Washington and Coeur d'Alene, Idaho during the heating season 1985--1986 and continued to monitor indoor radon quarterly and annually for ten years. The mitigation systems included active sub-slab ventilation, basement over-pressurization, and crawlspace isolation and ventilation. The occupants reported various operational problems with these early mitigation systems. The long-term radon measurements were essential to track the effectiveness of the mitigation systems over time. All 12 homes were visited during the second year of the study, while a second set 5 homes was visited during the fifth year to determine the cause(s) of increased radon in the homes. During these visits, the mitigation systems were inspected and measurements of system performance were made. Maintenance and modifications were performed to improve system performance in these homes.

    Long-term, normal-dose benzodiazepine treatment was discontinued in 16 patients who were suspected of being dependent on their medication. The withdrawal was gradual, placebo-controlled, and double-blind. All the patients experienced some form of withdrawal reaction, which ranged from anxiety and dysphoria to moderate affective and perceptual changes. Symptom ratings rose as the drugs were discontinued, but usually subsided to prewithdrawal levels over the next two to four weeks. Other features of the withdrawal included disturbance of sleep and appetite and noticeable weight loss. Electroencephalography showed appreciable reduction in fast-wave activity as the drugs were withdrawn, and an improvement in psychological performance was recorded by the Digit Symbol Substitution Test. Because of the risk of dependence on benzodiazepines these agents should probably not be given as regular daily treatment for chronic anxiety. PMID:6114776

    Liver transplantation allows long-term survival (10 years or more) in 75% of children receiving transplants before 2000. The risk of mortality after the first year is 4-10% in the next 10-20 years. Chronic rejection affects 6%. The need for late retransplantation is 3-5%. However, the follow-up of these patients involves the management of diverse problems in the graft (immunological, biliary, vascular) and others related to the use of immunosuppressants (renal dysfunction, lymphoproliferative syndrome). The transition from pediatric to adult care generates special needs. Adolescence and young adulthood are associated with a lack of compliance. Adult specialists should be aware of the special features of the original diagnosis and the surgical techniques used in childhood transplantation. Final quality of life is good overall but is lower than that in healthy young persons.

    Some photovoltaic module technologies use toxic materials. We report long-term leaching on photovoltaic module pieces of 5 × 5 cm2 size. The pieces are cut out from modules of the four major commercial photovoltaic technologies: crystalline and amorphous silicon, cadmium telluride as well as from copper indium gallium diselenide. To simulate different environmental conditions, leaching occurs at room temperature in three different water-based solutions with pH 3, 7, and 11. No agitation is performed to simulate more representative field conditions. After 360 days, about 1.4% of lead from crystalline silicon module pieces and 62% of cadmium from cadmium telluride module pieces are leached out in acidic solutions. The leaching depends heavily on the pH and the redox potential of the aqueous solutions and it increases with time. The leaching behavior is predictable by thermodynamic stability considerations. These predictions are in good agreement with the experimental results.

    Severe staff shortages in long-term care (LTC) make it difficult to meet the demands of the growing aging population. Further, technology-savvy Baby Boomers are expected to reshape the current institutional environments toward gaining more freedom and control in their care and lives. Voices from business, academia, research, advocacy organizations, and government bodies suggest that innovative technological approaches are the linchpin that may prepare society to cope with these projected demands. In this article, we review the current state of aging-related technology, identify potential areas for efficacy testing on improving the quality of life of LTC residents in future research, and discuss barriers to implementation of LTC technology. Finally, we present a vision of future technology use that could transform current care practices.

    Cosmonauts' exposure to cosmic rays during long-term spaceflight can cause unfavorable effects in health and risk for the crew members' lives. All unfavorable effects induced by exposure should be taken into consideration for the risk estimation. They should include both the acute deterministic effects and delayed effects called stochastic. On the ground the limitation of unfavorable consequences of acute exposure is achieved by means of establishing dose limits. But in space applications this approach can't be acceptable. Establishing a fixed dose limit is adequate to introducing indefinite reserve coefficient and therefore ineffective usage of spacecraft resource. The method of radiation risk calculation caused by acute and delayed effects of cosmonauts' exposure is discussed and substantiated in the report. Peculiarities of the impact of permanent radiation sources (galactic cosmic rays and trapped radiation) and the variable one (solar cosmic rays) are taken into consideration. c2002 COSPAR.

    A method and system for long-term control of root growth without killing the plants bearing those roots involves incorporating a 2,6-dinitroaniline in a polymer and disposing the polymer in an area in which root control is desired. This results in controlled release of the substituted aniline herbicide over a period of many years. Herbicides of this class have the property of preventing root elongation without translocating into other parts of the plant. The herbicide may be encapsulated in the polymer or mixed with it. The polymer-herbicide mixture may be formed into pellets, sheets, pipe gaskets, pipes for carrying water, or various other forms. The invention may be applied to other protection of buried hazardous wastes, protection of underground pipes, prevention of root intrusion beneath slabs, the dwarfing of trees or shrubs and other applications. The preferred herbicide is 4-difluoromethyl-N,N-dipropyl-2,6-dinitro-aniline, commonly known as trifluralin. 7 figs.

    A method and system for long-term control of root growth without killing the plants bearing those roots involves incorporating a 2,6-dinitroaniline in a polymer and disposing the polymer in an area in which root control is desired. This results in controlled release of the substituted aniline herbicide over a period of many years. Herbicides of this class have the property of preventing root elongation without translocating into other parts of the plant. The herbicide may be encapsulated in the polymer or mixed with it. The polymer-herbicide mixture may be formed into pellets, sheets, pipe gaskets, pipes for carrying water, or various other forms. The invention may be applied to other protection of buried hazardous wastes, protection of underground pipes, prevention of root intrusion beneath slabs, the dwarfing of trees or shrubs and other applications. The preferred herbicide is 4-difluoromethyl-N,N-dipropyl-2,6-dinitro-aniline, commonly known as trifluralin.

    The zonation of Typha populations in an experimental pond in Michigan was re-examined 15 years after the original sampling to gain insight into the long-term dynamics. Current distributions of Typha populations were also examined in additional experimental ponds at the site that have been maintained for 23 years. The zonation between T. latifolia and T. angustifolia in the previously studied pond 15 years after the initial sampling revealed that the density and distribution of shoots had not changed significantly. Thus, it appears that previously reported results (based on 7- year old populations) have remained consistent over time. Additional insight into the interaction between these two taxa was sought by comparing mixed and monoculture stands in five experimental ponds that have remained undisturbed for their 23-year history. The maximum depth of T. latifolia, the shallow- water species, was not significantly reduced when growing in the presence of the more flood tolerant T. angustifolia. In contrast, the minimum depth of T. angustifolia was reduced from 0 to 37 cm when in the presence of T. latifolia. When total populations were compared between monoculture and mixed stands, the average density of T. angustifolia shoots was 59.4 percent lower in mixed stands while the density of T. latifolia was 32 percent lower, with T. angustifolia most affected at shallow depths (reduced by 92 percent) and T. latifolia most affected at the deepest depths (reduced by 60 percent). These long-term observations indicate that competitive displacement between Typha taxa has remained stable over time.

    The robustness of the aa geomagnetic index is of critical importance to the debate about the previously reported doubling of the solar coronal magnetic field in the last 100 years, inferred from an increasing trend in this index. To test the trend in aa, we have reconstructed the aa index using two long-running European stations (Sodankylä from 1914 and Niemegk from 1890) to provide data for the northern component of the index that are independent of data from the UK observatories used in the "official" aa index. Both the fully "reconstructed" aa series, based on Sodankylä (67°N, L = 5.2 RE) and Niemegk (52°N, L = 2.3 RE) data in combination with the official aa Southern Hemisphere data, confirm the increasing trend in the index. The Niemegk-based index shows little solar cycle variation in its deviation from the official index, probably because of the midlatitude location of the station. The high-latitude station, Sodankylä, is more affected by active geomagnetic conditions during solar maximum because of the proximity of the auroral oval to the station. Nevertheless, its index also clearly confirms the increasing trend in the aa index and hence supports the idea of a long-term increase in solar coronal magnetic field strength. As an added test, we reconstructed the aa index from a single site using data from two long-running UK stations, Eskdalemuir and Lerwick, applying a technique known as interhourly variation (IHV) proposed by Svalgaard et al. (2004). The resulting series is designed to be primarily sensitive to solar wind conditions. Both the reconstructed aaIHV also showed an increasing trend with time and high consistency with the official aa index. Overall, we conclude that the robustness of the trend in the aa index supports the idea of a long-term increase in solar coronal magnetic field strength.

    Posterior urethral valves represent the most common cause of bladder outlet obstruction in infancy that impairs renal and bladder function. Long-term outcome of patients with previous PUV is evaluated. Patients over 18 years of age, treated from 1982 to 1995 before the age of 3 years were considered. Previous surgery, renal function, bladder activity, urinary incontinence, and fertility/sexual activity were evaluated. Clinical interview, creatinine clearance, uroflowmetry with ultrasound post-void urine residue, and self-administered questionnaire were recorded. Out of 45 identified records, 24 patients (53.3%) accepted to be enrolled (age 18-34 years, mean 23 years). The mean follow-up was 19.5 years (16-30 years). Out of the 21 excluded patients, 20 did not reply to the clinical interview and 1 died at age of 6 years. All the 24 patients had early endoscopic section of PUV; nine also received transient ureterocutaneostomy or vesicostomy. Ureteroneocystostomy was performed in five patients and ureterocystoplasty with unilateral nephrectomy in two. At follow-up chronic renal failure was detected in 13 patients (54.1%) and 9 (37.5%) had arterial hypertension. End-stage renal disease developed in five patients (20.8%): three had successful renal transplantation and two were in dialysis. Lower urinary tract symptoms were present in seven patients (29.1%). No significant fertility deficit and sexual dysfunction were observed in 23 patients, while 1 patient was azoospermic. No paternity was reported so far. Long-term outcome of patients with previously treated PUV is mandatory. Kidney, bladder, and sexual functions should be monitored till adulthood to verify any modified behaviour.

    Background Rhegmatogenous retinal detachment is a commonly encountered retinal problem where rapid treatment can prevent irreversible vision loss. Pneumatic retinopexy (PR) is a simple, minimally invasive procedure for retinal reattachment. Purpose This study aimed to assess the long-term anatomical and functional outcome of pneumatic retinopexy in primary rhegmatogenous retinal detachment. Patients and methods A prospective interventional study was performed. Subjects with rhegmatogenous retinal detachment who underwent pneumatic retinopexy from May 2006 to May 2007 at Menoufiya University Hospital were included in this study with at least 3 years follow-up. Results A total of 40 cases were included in the study. The mean age of patients was 44.25 ± 10.85 years. Reattachment of the retina was achieved in 100% of cases. In 75% of cases, the primary intervention was successful. However, the retina redetached in 20% of these during the first 6 months, requiring reinjection or another procedure. Three years after the first intervention, follow-up measurement of the mean visual acuity of the eyes without reoperation was 0.40 ± 0.21 while the mean visual acuity of the eyes which needed additional operations was 0.22 ± 0.13. Conclusion Sixty percent of the cases obtained long-term retinal reattachment with a single operation success (SOS), with good visual recovery and less morbidity than other more invasive procedures like scleral buckling or pars plana vitrectomy, translating to higher productivity for the patient. This procedure, being quicker than the alternatives, also saves the surgeon’s time, making PR a good choice for managing primary rhegmatogenous retinal detachment in developing countries.

    The U.S. Department of Energy (DOE) is responsible for managing vast amounts of information documenting historical and current operations. This information is critical to the operations of the DOE Office of Legacy Management. Managing legacy records and information is challenging in terms of accessibility and changing technology. The Office of Legacy Management is meeting these challenges by making records and information management an organizational priority. The Office of Legacy Management mission is to manage DOE post-closure responsibilities at former Cold War weapons sites to ensure the future protection of human health and the environment. These responsibilities include environmental stewardship and long-term preservation and management of operational and environmental cleanup records associated with each site. A primary organizational goal for the Office of Legacy Management is to 'Preserve, Protect, and Share Records and Information'. Managing records for long-term preservation is an important responsibility. Adequate and dedicated resources and management support are required to perform this responsibility successfully. Records tell the story of an organization and may be required to defend an organization in court, provide historical information, identify lessons learned, or provide valuable information for researchers. Loss of records or the inability to retrieve records because of poor records management processes can have serious consequences and even lead to an organisation's downfall. Organizations must invest time and resources to establish a good records management program because of its significance to the organization as a whole. The Office of Legacy Management will continue to research and apply innovative ways of doing business to ensure that the organization stays at the forefront of effective records and information management. DOE is committed to preserving records that document our nation's Cold War legacy, and the Office of Legacy

  8. Dynamics of long-term genomic selection

    PubMed Central

    2010-01-01

    Background Simulation and empirical studies of genomic selection (GS) show accuracies sufficient to generate rapid gains in early selection cycles. Beyond those cycles, allele frequency changes, recombination, and inbreeding make analytical prediction of gain impossible. The impacts of GS on long-term gain should be studied prior to its implementation. Methods A simulation case-study of this issue was done for barley, an inbred crop. On the basis of marker data on 192 breeding lines from an elite six-row spring barley program, stochastic simulation was used to explore the effects of large or small initial training populations with heritabilities of 0.2 or 0.5, applying GS before or after phenotyping, and applying additional weight on low-frequency favorable marker alleles. Genomic predictions were from ridge regression or a Bayesian analysis. Results Assuming that applying GS prior to phenotyping shortened breeding cycle time by 50%, this practice strongly increased early selection gains but also caused the loss of many favorable QTL alleles, leading to loss of genetic variance, loss of GS accuracy, and a low selection plateau. Placing additional weight on low-frequency favorable marker alleles, however, allowed GS to increase their frequency earlier on, causing an initial increase in genetic variance. This dynamic led to higher long-term gain while mitigating losses in short-term gain. Weighted GS also increased the maintenance of marker polymorphism, ensuring that QTL-marker linkage disequilibrium was higher than in unweighted GS. Conclusions Losing favorable alleles that are in weak linkage disequilibrium with markers is perhaps inevitable when using GS. Placing additional weight on low-frequency favorable alleles, however, may reduce the rate of loss of such alleles to below that of phenotypic selection. Applying such weights at the beginning of GS implementation is important. PMID:20712894

    Gonococcal arthritis is the most common acute septic arthritis in sexually active young adults. It is caused by the gram-negative diplococcus Neisseria gonorrhoeae. In 0.5-3% an untreated mucosal infection disseminates throughout the system and affects mostly big joints like the knee, elbows, and ankles. N. gonorrhoeae is a fragile microorganism which is difficult to culture. Penicillin resistance has developed worldwide in recent years, therefore, patients should be treated by a third generation Cephalosporin. In this article, we describe the unexpected finding of septic arthritis in the proximal interphalangeal joint of a 50-year-old patient. The septic arthritis was caused by N. gonorrhoeae.

    Chronic dermatologic diseases affect millions of people. The long-term nature of these diseases creates psychological and financial burden as well as substantially impacts patients' quality of life. Biologics, including adalimumab, etanercept, alefacept, efalizumab, and infliximab, are the newest therapeutic agents in the treatment of moderate-to-severe psoriasis and psoriatic arthritis and have been used in a variety of other dermatologic diseases. These agents act relatively quickly and effectively in 12-week clinical trials. Because these agents are used to treat patients for longer than 12 weeks, there is a need to review the safety and efficacy of these agents over longer periods of time. Many levels of evidence are available for biologics including high level of evidence from large, randomized, double-blind, placebo-controlled clinical studies. This review focuses on the available data for efficacy and safety for greater than 24 weeks of therapy. The studies supporting the use of rituximab and intravenous immunoglobulin in autoimmune blistering diseases are also presented in this review. PMID:19222514

    Rheumatoid arthritis is characterised by persistent synovitis, systemic inflammation, and autoantibodies (particularly to rheumatoid factor and citrullinated peptide). 50% of the risk for development of rheumatoid arthritis is attributable to genetic factors. Smoking is the main environmental risk. In industrialised countries, rheumatoid arthritis affects 0·5-1·0% of adults, with 5-50 per 100 000 new cases annually. The disorder is most typical in women and elderly people. Uncontrolled active rheumatoid arthritis causes joint damage, disability, decreased quality of life, and cardiovascular and other comorbidities. Disease-modifying antirheumatic drugs (DMARDs), the key therapeutic agents, reduce synovitis and systemic inflammation and improve function. The leading DMARD is methotrexate, which can be combined with other drugs of this type. Biological agents are used when arthritis is uncontrolled or toxic effects arise with DMARDs. Tumour necrosis factor inhibitors were the first biological agents, followed by abatacept, rituximab, and tocilizumab. Infections and high costs restrict prescription of biological agents. Long-term remission induced by intensive, short-term treatment selected by biomarker profiles is the ultimate goal.
