1/11. Acute metastatic infection of a revision total hip arthroplasty with oral bacteria after noninvasive dental treatment.The risk of hematogenous bacterial infection of a total joint prosthesis is currently considered to be greatest in the 2 years after arthroplasty or when the patient is chronically ill or immunocompromised, for dental treatments that are considered invasive, with a higher incidence of bacteremia. We report the case of a healthy man who had undergone revision hip arthroplasty 11 months previously and who developed acute signs of infection of the hip prosthesis with an oral organism 30 hours after supragingival dental cleaning, performed with the specific intention to be noninvasive, without antibiotic prophylaxis.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
2/11. Primary arthroplasty of infected hips and knees in special cases using antibiotic-loaded bone-cement for fixation.As a consequence of successful 1-stage exchange of infected joint prostheses, we decided to treat bacterial infection of the hip or knee by joint resection, synovectomy, and primary implantation of a hip or stabilized knee prosthesis. Since 1984, we have performed this procedure on 51 hips and 32 knees. All operations were preceded by identification of the causative organism and choice of appropriate antibiotics for addition to the bone-cement. The long-term rate of success corresponds to that of 1-stage exchange of infected prostheses. The different anatomic conditions at the hip and knee have to be taken into consideration. This treatment is restricted to special cases and should be performed only in specialized clinics with competent assistance from a bacteriologist.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
3/11. Mucoraceae infections of antibiotic-loaded cement spacers in the treatment of bacterial infections caused by knee arthroplasty.Two clinical cases of mycotic infections secondary to knee spacers medicated with antibiotics against bacterial infections are presented. Care must be taken between the first and second stage (when the spacer is in place), and attention must be paid to the management of the surgical wound to avoid secondary contamination.- - - - - - - - - - ranking = 5keywords = bacterial infection (Clic here for more details about this article) |
4/11. Posterior dislocation of a cruciate-retaining total knee arthroplasty following an acute bacterial infection.BACKGROUND: We report a rare complication of posterior dislocation of a cruciate-retaining total knee arthroplasty following an acute bacterial infection. The mechanism of dislocation proved to be septic loosening of the femoral component and a tear of the posterior cruciate ligament near to the femoral insertion site. The tear arose during the treatment of acute septic arthritis following total knee arthroplasty when the patient attempted full weight-bearing with the affected limb in a semiflexion position and twisted the knee. methods AND RESULTS: Successful treatment was provided with subsequent surgical debridement, removal of the loosened prosthesis, the application of systemic antibiotics, and a revision total knee arthroplasty utilizing a posteriorly stabilized prosthesis after adequate control of the infection. CONCLUSION: Soft-tissue protection from full weight-bearing of the knee during the treatment of an acute infection following total knee arthroplasty and timely removal of the loosened total knee prosthesis are recommended in order to prevent such a complication.- - - - - - - - - - ranking = 5keywords = bacterial infection (Clic here for more details about this article) |
5/11. Sterile inflammation associated with transradial catheterization and hydrophilic sheaths.In 1999, we noted the development of inflammation and/or abscesses at the site of radial access in a group of patients. Over a 3-year period, we noted this inflammation in 33 patients out of 2,038 (1.6%) who had catheterization via the radial approach. The radial abscesses occurred in 30 patients out of 1,063 (2.8%) in whom we could confirm the use of a hydrophilic-coated sheath, but in no patient for whom we can document that an uncoated sheath was used. No infectious agent could be implicated, and the time course for the development of the abscess, typically 2 to 3 weeks, seemed long for a bacterial infection. Later patients had biopsies, and granulomatous reactions were seen in most. Additionally, a few of the biopsies showed an amorphous extravascular substance consistent with the catheter coating. All patients had good long-term outcomes.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
6/11. A patient with MRSA infection to prosthesis of femoral head diagnosed non-invasively using bi-digital O-ring test: a clinical case report.Prosthesis of femoral head is a common surgical procedure, but the diagnosis of infection associated with the prosthesis remains difficult. We diagnosed non-invasively methicillin resistant staphylococcus aureus (MRSA) infection of prosthesis of femoral head with Bi-Digital O-Ring Test (BDORT). BDORT uses the resonance phenomenon between 2 identical substances, and electromagnetic field principle. The method can non-invasively detect viral & bacterial infection. Accuracy of the BDORT findings was confirmed through bacterial culture & sensitivity test to antibiotics. Patient was successfully treated with operation of evulsion of the prosthesis of femoral head and administration of antibiotics and Cilantro. The drug compatibility was tested with BDORT. BDORT was an effective technique for non-invasively detecting infection of prosthesis and selecting the most effective antibiotics.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
7/11. Six cases of bacterial infection in porous orbital implants.BACKGROUND: We present 6 cases of bacterial infection that developed after porous orbital implant surgery. CASES: Five patients with hydroxyapatite implants showed lid swelling, discharge, and suppurative granuloma 14 days to 3 years after surgery. The hydroxyapatite implants were removed 14 days to 41 months postoperatively, and synthetic porous polyethylene orbital implants were inserted. Thick discharge and conjunctival melting was noted 14 months after primary Medpor implant surgery in the sixth patient, and the infection was controlled by medical therapy. OBSERVATIONS: The culture of specimens removed with swabs from the conjunctiva of patients and from the hydroxyapatite implants showed growth of staphylococcus aureus, staphylococcus epidermidis, alpha-hemolytic streptococcus and peptostreptococcus in 4 patients, whereas streptococcus pyogenes were cultured from the conjunctiva in the Medpor implant patient. culture for the remaining patient was negative .CONCLUSIONS: If there is continuous pain, injection, and discharge after porous implant insertion, bacterial infection in the implant should be considered immediately. Systemic antibiotics and topical eye drops should be administered without delay. If no improvement is observed, the implant should be removed and a different approach must be considered.- - - - - - - - - - ranking = 6keywords = bacterial infection (Clic here for more details about this article) |
8/11. Immediate autogenous cartilage grafts in rhinoplasty after alloplastic implant rejection.BACKGROUND: It is accepted in rhinoplasty that complications are more common with alloplastic implants than with autografts. There is little guidance in the literature on how to deal with the cosmetic and/or functional problems that follow alloplastic implant rejection. The conventional advice has been to remove the allograft and not place any graft at the same time. The present article presents our experience treating allograft rejection and immediately repairing any structural defect with autografts. OBJECTIVE: To demonstrate that immediate nasal reconstruction using autogenous cartilage is a good technique when an alloplastic material has to be removed because of rejection, inflammation, or infection. DESIGN: A retrospective analysis of outcome for a case series. methods: A retrospective review of the management of 8 patients who presented to 2 tertiary referral centers with alloplastic implant rejection following rhinoplasty. In 7 cases, the alloplastic implant had to be removed because it had migrated and caused a foreign body reaction; in 1 case, the implant had caused a bacterial infection. RESULTS: In all 8 cases, the nasal deformity that followed the removal of the allograft was so marked that the nose was immediately reconstructed with autogenous cartilage. The patients all made a good recovery after immediate reconstruction, although skin changes associated with the alloplastic implant remained after a mean follow-up of 3 years 3 months. CONCLUSION: The use of autogenous cartilage is a good option for nasal augmentation immediately after the removal of an alloplastic implant.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
9/11. Periprosthetic mycobacterial infection. CT and mammographic findings.Organisms of the mycobacterium fortuitum complex are an uncommon but important cause of periprosthetic infection following augmentation mammoplasty or other breast surgery. This etiological agent must be considered in the particular case of periprosthetic infection, because special handling of the fluid is crucial to enhance recovery of the organism. We describe the computed tomography (CT) and mammographic findings in such an abscess with respect to the clinical context and subsequent management. To our knowledge, CT findings associated with any periprosthetic breast infection have not been described.- - - - - - - - - - ranking = 4keywords = bacterial infection (Clic here for more details about this article) |
10/11. ciprofloxacin treatment of bacterial endocarditis involving prosthetic material after cardiac surgery.Two children with cyanotic congenital heart disease and Gram negative bacterial infection of prosthetic material after cardiac surgery were treated successfully with oral ciprofloxacin, initially in combination with netilmicin. The use of oral ciprofloxacin allowed prolonged outpatient treatment to be given, avoiding the need for intravenous access and early repeat surgery.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
