An 80-Year-Old Man With Persistent Enterococcus faecalis Bacteremia.

CASE PRESENTATION: An 80-year old man presented to the ED after being found down in his home. He had gone to the restroom to perform straight catheterization, as he normally does for his enlarged prostate, and was found slumped over and confused. On arrival to the ED, he was found to be in atrial fibrillation with rapid ventricular response, febrile, and hypotensive. CT imaging of his head, chest, and abdomen-pelvis was obtained. He was started on broad-spectrum antibiotics and norepinephrine infusion for presumed urinary septic shock and admitted to the medical critical care unit for further management.

What Are the Long-term Outcomes of Mortality, Quality of Life, and Hip Function after Prosthetic Joint Infection of the Hip? A 10-year Follow-up from Sweden.

BACKGROUND: Prosthetic joint infection (PJI) is a complication after arthroplasty that negatively affects patient health. However, prior reports have not addressed the long-term consequences of hip PJI in terms of patient mortality, quality of life, and hip function. QUESTIONS/PURPOSES: At a minimum of 10 years after PJI in patients undergoing primary THA, in the context of several large, national databases in Sweden, we asked: (1) Is mortality increased for patients with PJI after THA compared with patients with a noninfected THA? (2) Does PJI of the hip have a negative influence on quality of life as measured by the Euro-QoL-5D-5L (EQ-5D-5L), ambulatory aids, residential status, and hip function as measured by the Oxford Hip Score (OHS)? (3) Which factors are associated with poor patient-reported outcome measures (PROMs) for patients with PJI after primary THA? METHODS: This study included 442 patients with a PJI after primary THA, from a previously published national study, including all patients with a THA performed from 2005 to 2008 in Sweden (n = 45,570) recruited from the Swedish Hip Arthroplasty Registry (SHAR). Possible deep PJIs were identified in the Swedish Dispensed Drug Registry and verified by review of medical records. Mortality in patients with PJI was compared with the remaining cohort of 45,128 patients undergoing primary THA who did not have PJI. Mortality data were retrieved from the SHAR, which in turn is updated daily from the population registry. A subgroup analysis of patients who underwent primary THA in 2008 was performed to adjust for the effect of comorbidities on mortality, as American Society of Anesthesiologists (ASA) scores became available in the SHAR at that time. For the PROM analysis, we identified three controls matched by age, gender, indication for surgery, and year of operation to each living PJI patient. A questionnaire including EQ-5D-5L, ambulatory aids, residential status, and OHS was collected from patients with PJI and controls at a mean of 11 years from the primary procedure. Apart from age and gender, we analyzed reoperation data (such as number of reoperations and surgical approach) and final prosthesis in situ to explore possible factors associated with poor PROM results. RESULTS: After controlling for differences in sex, age, and indication for surgery, we found the all-cause 10-year mortality higher for patients with PJI (45%) compared with patients undergoing THA without PJI (29%) (odds ratio 1.4 [95% CI 1.2 to 1.6]; p < 0.001). The questionnaire, with a minimum of 10 years of follow-up, revealed a lower EQ-5D-5L index score (0.83 versus 0.94, -0.13 [95% CI -0.18 to -0.08; p < 0.001]), greater proportion of assisted living (21% versus 12%, OR 2.0 [95% CI 1.2 to 3.3]; p = 0.01), greater need of ambulatory aids (65% versus 42%, OR 3.1 [95% 2.1 to 4.8]; p < 0.001), and a lower OHS score (36 versus 44, -5.9 [-7.7 to -4.0]; p < 0.001) for patients with PJI than for matched controls. Factors associated with lower OHS score for patients with PJI were three or more reoperations (-8.0 [95% CI -13.0 to -3.2]; p = 0.01) and a direct lateral approach used at revision surgery compared with a posterior approach (-4.3 [95% CI -7.7 to -0.9]; p = 0.01). CONCLUSION: In this study, we found that PJI after THA has a negative impact on mortality, long-term health-related quality of life, and hip function. Furthermore, the subgroup analysis showed that modifiable factors such as the number of reoperations and surgical approach are associated with poorer hip function. This emphasizes the importance of prompt, proper initial treatment to reduce repeated surgery to minimize the negative long-term effects of hip PJI. LEVEL OF EVIDENCE: Level III, therapeutic study.

Results of Obturator Foramen Bypass in Patients with Groin Infection and Arterial Involvement.

BACKGROUND: Arterial bypass tunneling via the obturator foramen (OFB) can be performed to circumvent groin infections during lower extremity revascularization. The objective of this study is to report safety and efficacy outcomes of OFB in the setting of infected femoral pseudoaneurysms and infected prosthetic femoral bypass grafts. METHODS: A multihospital, single-entity healthcare system retrospective review was conducted for all patients who underwent OFB between January 2014 through June 2020. Any patient >18 years of age who underwent OFB in the setting of groin infection with a minimum of 30 days follow-up was included in the trial. Demographic, operative, and clinical characteristics of patients were gathered during chart review. Statistical analysis was performed using Microsoft Excel and R studio. RESULTS: Seventeen patients underwent OFB during the defined time-period. Demographic data are presented in the first table (Demographic Characteristics). Mean American Society of Anesthesiologists score was 3.25. Mean estimated blood loss was 500 mL. Mean operative time was 307 min. Mean follow-up time was 8.5 months (range 0-35 months). In total, 41.2% patients underwent fluoroscopic-guided tunneling, and, when compared to blind tunneling, showed no difference in intraoperative complications or operative time (P value 0.3). In total, 52.9% of patients required ICU admission resulting in a mean number of 0.8 ICU days. The overall mean length of stay was 16.8 days. Two major amputations were reported during follow-up. Patient mortality within 30 days was 0%. Primary patency within 30 days was 100%. Intravenous drug use was not associated with an increased number of subsequent groin wound procedures (P value 0.3). Intravenous drug use was not associated with concomitant methicillin-resistant Staphylococcus aureus infection (P value 0.3). CONCLUSION: OFB is a safe and effective surgical option in patients who are unable to undergo anatomic tunneling during lower extremity bypass. OFB is associated with favorable rates of primary patency and amputation-free survival at midterm follow-up.

Pantaloon Vein Grafts - An Alternative Fix for an Old Problem.

BACKGROUND: Pantaloon vein grafts (PVG) were first used to replace infrarenal aortic grafts. However, they may have other applications, such as femoral aortic bifurcation reconstruction. METHODS: We herein present 2 different cases, the first with a prosthetic graft infection at the recipient femoral bifurcation, the second for a late occlusion of the femoral bifurcation following endarterectomy and prosthetic patch closure, who were treated with PVG fashioned from the ipsilateral great saphenous vein. CONCLUSION: The use of PVG to reconstruct the femoral bifurcation allowed for concurrent axial and profunda femoris artery revascularization, while correcting diameter mismatch with the inflow source and seem particularly suitable for infected operative fields.

Novel prefabricated bovine pericardial grafts as alternate conduit for septic aortoiliac reconstruction.

OBJECTIVE: Infection of prosthetic aortic grafts represents a serious complication with high morbidity and mortality. Replacement with autologous material is recommended; however, in its absence, biological material should be favored. In the present retrospective cohort study, we evaluated the short- and midterm results with the use of commercially available prefabricated bovine pericardium grafts (BPGs) used for the management of aortic graft infection or aortic reconstructive surgery in the presence of systemic infection. METHODS: We performed a retrospective analysis of patients in whom BPGs had been used for aortic reconstruction at two vascular centers. Prefabricated vascular pericardium grafts were preferred over other biological reconstruction techniques for selected cases. Comorbidities, procedure-related details, perioperative morbidity, clinical outcomes, and mortality were analyzed. RESULTS: From 2014 to 2019, 21 patients had received BPGs at two Austrian vascular centers. Their median age was 63 years (interquartile range [IQR], 55-71 years), the patients were predominantly male (76%), and the median body mass index was 25.3 kg/m2 (IQR, 21.7-27.3 kg/m2). The major comorbidities included arterial hypertension, peripheral artery disease, smoking, and chronic pulmonary disease. The indications for surgery were vascular graft or endograft infection in 62% and aortic reconstruction in the presence of systemic infection in 38%. Three patients (14%) had aortoenteric fistulas. Surgery was technically successful in all cases. The median follow-up was 21.6 months (IQR, 6.0-34.6 months). The 30-day mortality was 9.5%. The 1- and 2-year overall survival was 84% and 75%, respectively. Of the 21 patients, 89% had remained free of recurrent infection. One of the two reinfections had resolved after treatment of the underlying focus. At 2 years, the primary and assisted primary patency rates were 86% and 94%, respectively. No limbs were lost during follow-up. CONCLUSIONS: Prefabricated BPGs represent a promising alternative for the management of aortic graft infections and aortoiliac reconstruction in the presence of systemic infection.

Fluorodeoxyglucose Applications in Cardiac PET: Viability, Inflammation, Infection, and Beyond.

With its high temporal and spatial resolution and relatively low radiation exposure, positron emission tomography (PET) is increasingly being used in the management of cardiac patients, particularly those with inflammatory cardiomyopathies such as sarcoidosis. This review discusses the role of PET imaging in assessing myocardial viability, inflammatory cardiomyopathies, and endocarditis; describes the different protocols needed to acquire images for specific imaging tests; and examines imaging interpretation for each image dataset-including identification of the mismatch defect in viability imaging, which is associated with significant improvement in LV function after revascularization. We also review the role of fluorodeoxyglucose PET in cardiac sarcoidosis diagnosis, the complementary role of magnetic resonance imaging in inflammatory cardiomyopathy, and the emerging use of cardiac PET in prosthetic valve endocarditis.

Biofilm and Chronic Nonhealing Wound Infections.

In this review, the author summarizes the role of biofilm formation in chronic nonhealing wound infections along with characteristics of biofilm formation, diagnosis, detection, and treatment. Because biofilms are still not clearly understood, treatment and diagnosis are currently difficult.

Cardiovascular Imaging in Infective Endocarditis: A Multimodality Approach.

Multimodality imaging plays a pivotal role in the evaluation and management of infective endocarditis (IE)-a condition with high morbidity and mortality. The diagnosis of IE is primarily based on the modified Duke criteria with echocardiography as the first-line imaging modality. Both transthoracic and transesophageal echocardiography delineate vegetation location and size, assess for paravalvular extension of infection, and have the added advantage of defining the hemodynamic effects of valvular or device infection. Native and prosthetic valve IE, infections relating to cardiac implantable electronic devices, and indwelling catheters are effectively evaluated with echocardiography. However, complementary imaging is occasionally required when there remains diagnostic uncertainty following transesophageal echocardiography. Multidetector computed tomography and nuclear imaging techniques such as positron emission tomography and white blood cell scintigraphy have been shown to reduce the rate of misdiagnosed IE particularly in the setting of prosthetic valve endocarditis, paravalvular extension of infection, and cardiac implantable electronic devices. In this review, we describe a modern approach to cardiac imaging in native and prosthetic valve endocarditis, as well as cardiac implantable electronic devices including pacing devices and left ventricular assist devices. Current guidelines addressing the role of multimodality imaging in IE are discussed. The utility of imaging in the assessment of local and distant endocarditis complications such as pericardial sequelae, myocarditis, and embolic events is also addressed.

Arteriovenous Grafts' Types of Indications and Their Infection Rate.

BACKGROUND: Arteriovenous graft infection is a well-known and frequent complication. The objective of this study was to compare infection rates of primary and secondary indicated arteriovenous grafts (AVGs). SUBJECTS AND METHODS: Retrospectively, we evaluated the indications for AVGs created at our institution which became infected. One hundred forty AVGs were evaluated. Of these AVGs, 33 (23.6%) were primary and 107 (76.4%) secondary indicated. RESULTS: Infection of a primary AVG was detected in 5 patients (15.2 %). Infection of a secondary AVG was detected in 30 patients (28.0%). Primary and secondary patency were significantly lower in patients with infected AVG (P = 0.006; P = 0.0001). The effect of diabetes mellitus and age on development of infection was not confirmed. CONCLUSIONS: Indications for AVG creation clearly influence the future risk of infection. If the indication to use the AVG is to correct a complicated arteriovenous fistula, the risk of infection is 2 times higher.

Periprosthetic joint infection with streptococcus dysgalactiae subspecies equisimilis: Case report.

Streptococcus dysgalactiae (SD) is a common pathogen among elderly population. However, to our knowledge, there is no periprosthetic joint infection case reported that is infected with Streptococcus dysgalactiae subspecies equisimilis (SDSE) in the English literature. In this article, we report a 77-year-old male patient who had undergone total knee arthroplasty three years ago and had the diagnosis of cellulitis at his leg followed by swelling, pain and hyperemia localized at his knee. Three knee aspirations were performed and the SDSE was identified. There was no direct contact of patient to animals.

Rabbit model of Staphylococcus aureus implant-associated spinal infection.

Post-surgical implant-associated spinal infection is a devastating complication commonly caused by Staphylococcus aureus Biofilm formation is thought to reduce penetration of antibiotics and immune cells, contributing to chronic and difficult-to-treat infections. A rabbit model of a posterior-approach spinal surgery was created, in which bilateral titanium pedicle screws were interconnected by a plate at the level of lumbar vertebra L6 and inoculated with a methicillin-resistant S.aureus (MRSA) bioluminescent strain. In vivo whole-animal bioluminescence imaging (BLI) and ex vivo bacterial cultures demonstrated a peak in bacterial burden by day 14, when wound dehiscence occurred. Structures suggestive of biofilm, visualized by scanning electron microscopy, were evident up to 56 days following infection. Infection-induced inflammation and bone remodeling were also monitored using 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) and computed tomography (CT). PET imaging signals were noted in the soft tissue and bone surrounding the implanted materials. CT imaging demonstrated marked bone remodeling and a decrease in dense bone at the infection sites. This rabbit model of implant-associated spinal infection provides a valuable preclinical in vivo approach to investigate the pathogenesis of implant-associated spinal infections and to evaluate novel therapeutics.

CONCLUSIONS: Risk factors for prosthetic knee infection identified in this study are preventable. The main risk factors were obesity, diabetes mellitus type 2, superficial wound infection and persistent drainage, which were considered together or separately to be risk factors in the population studied

Coronary Drug-Eluting Stent Infection Complicated by Coronary Artery Aneurysm and Purulent Pericarditis: Complete Resolution Without Surgery.

Coronary stent infection is considered to be a rare but catastrophic complication of percutaneous coronary intervention. In this report, we present a 72-year-old man who developed a coronary stent infection complicated by coronary aneurysm and purulent pericarditis. Coronary artery aneurysm resolved over a period of 8 months following the successful management of infection with intensive antibiotic therapy alone. This case suggests that conservative therapy can be a therapeutic option in patients with high operative risks.

Economic impact of cardiac implantable electronic device infections: cost analysis at one year in a large U.S. health insurer.

Aims: Cardiac device infections (CDIs) are serious adverse events associated with morbidity and mortality, significant costs and increased healthcare utilization. The objective of the current study was to characterize the CDI rate by device type, risk factors for infection and healthcare costs from a large U.S. health insurer perspective.Materials and Methods: A retrospective analysis of a large U.S. health insurer database identified commercial and Medicare Advantage with Part D (MAPD) members ≥18 years with ≥1 claim for a cardiac implantable electronic device (CIED) procedure between 01 October 2011 and 31 October 2015. CIEDs included pacemakers (IPG), implantable cardioverter defibrillators (ICDs), and cardiac resynchronization therapy - pacemakers without (CRT-P) and with defibrillation (CRT-D). Probabilities of CDI through one-year post implant were estimated using the Kaplan-Meier method. A regression model with stepwise variable selection was used to select risk factors associated with CDIs.Results: A total of 63,406 patients were included with an overall CDI rate of 1.28% (1.0% de novo and 1.74% replacement devices), varying by device type: IPG = 0.91%; ICD = 1.63%; CRT-p = 1.50%; CRT-D = 2.22%. The average adjusted annual medical costs were 2.4 times greater [95% confidence interval (CI) = 2.1-2.7] for those with an infection compared to those without, and the incremental cost difference was estimated to be $57,322 [95% CI $46,572-$70,484]. Observed risk factors of CDIs included prior device infection [Odds ratio (OR) = 11.356; 95% CI = 7.923-16.276], undergoing a CIED replacement procedure (OR = 1.644; 95% CI = 1.361-1.987), implantation of a high-power device (OR = 1.354; 95% CI = 1.115-1.643), and younger age (age < 65) (OR = 1.607; 95% CI = 1.307-1.976).Conclusions: The CDI rate at one year ranged from 0.91%-2.22% depending on device type. Management of CDIs among commercial and MAPD members is associated with high healthcare expenditures.

Clinically available reinforcing materials for soft tissue reconstruction.

Navigating the rapidly evolving field of materials for soft tissue reinforcement is challenging given the volume of clinically available options. Additionally, the current generally accepted classifications of these mesh materials confound the understanding of their utility by grouping disparate materials that have attributes overlapping category boundaries and that do not fully consider their clinically functionality. This review article highlights, from a materials science perspective, the most important attributes of these materials to improve the clinical decision-making process in the selection of the most appropriate features and design for the patient, surgery and clinical need. These characteristics include the physical attributes that directly impact the surgical procedure and immediate postoperative mechanical requirements as well as the post-implantation properties such as an adequate reinforcement time, strength of the resulting tissue and infection risk profile.

Iliac Remote Endarterectomy to Restore Circulation in a Patient with Infected Aorto-Femoral and Axillo-Bifemoral Bypasses.

We report a case of a patient who underwent a 2-stage operation that included a right obturator bypass with left iliac remote endarterectomy followed by removal of an infected, previously failed aorto-right-femoral and right axillo-bifemoral bypass reconstructions.

Delayed total hip arthroplasty infection with Mycobacterium Tuberculosis complex.

Total Hip Arthroplasty (THA) joint infection is an uncommon (0,3-1,7%) (20) but devastating complication after THA. While mostly caused by Gram-positive bacteria, with staphylococci and streptococci accounting for up to 76% of cases (21), orthopaedic surgeons are sometimes faced with atypical germs such as fungi or mycobacteria. We present a case of THA joint infection caused by Mycobacterium tuberculosis (MT) in a patient without a previous history of MT infection. A literature review was performed, and the treatment is discussed.

Prosthetic joint infection due to Mycobacterium bovis 5-years after BCG-instillations.

The Bacillus Calmette-Guerin (BCG) has been used as intravesical immunotherapy for superficial urothelial bladder carcinoma in preventing its recurrence. Prosthetic joint infections due to those instillations are very rare and few practitioners know this side effect. We report the case of a 77-year old male with a medical history of right hip replacement and super- ficial urothelial bladder carcinoma treated with BCG-instillations. He presented with a painful hip joint and extreme difficulty at walking. Because of high suspicion of prosthetic joint infection, a 2-stage arthroplasty was performed. Microbiological culture revealed Mycobacterium bovis so he was kept on antituberculous therapy for twelve months. Remarkable is the delay between the instillations and the acquisition of the prosthetic joint infection. A medical history of BCG instillations should warrant the practitioner for a possible joint infection. There are no current guidelines concerning the therapy.

Complete versus partial excision of infected arteriovenous grafts: Does remnant graft material impact outcomes?

OBJECTIVE: Infected arteriovenous grafts necessitate intervention to obtain source control. However, excising the graft material can be challenging and can lead to complications. Leaving a cuff of graft at the sites of anastomosis allows for the avoidance of potential risks. However, it is unclear whether doing so places patients at risk of recurrent graft infection. The purpose of the present study was to investigate the effect of complete vs partial excision of infected arteriovenous prosthetic dialysis access grafts. METHODS: The data from all patients who had undergone surgical intervention for infected arteriovenous grafts at a single institution were retrospectively reviewed. The patients were grouped according to intervention type: complete excision and partial excision of arteriovenous prosthetic grafts. Partial excisions were further substratified based on whether flow had been restored through the arteriovenous access. The primary outcome was freedom from subsequent intervention for infection, defined as the number of days from excision to subsequent reoperation for reinfection. Freedom from infection was analyzed using the Kaplan-Meier method. RESULTS: A total of 117 patients had undergone surgical intervention for 122 infected arteriovenous grafts from 2003 to 2016. Of these 117 patients, 79 (64.8%) had undergone partial excision of infected arteriovenous grafts, and 43 (35.2%) had undergone complete excision with vascular repair. Within the partial excision cohort, 71 infected arteriovenous grafts (58.2%) were not flow restored and 8 (6.6%) were flow restored using either prosthetic or autogenous interpositions. The median follow-up time was 2.4 years (interquartile range, 0.6-4.5 years). The most common causative organisms included methicillin-resistant Staphylococcus aureus (n = 34; 27.9%), methicillin-sensitive S. aureus (n = 17; 13.9%), and S. epidermidis (n = 15; 12.3%). The recurrent infection rate in the partial excision group was 16.5% (n = 13) compared with 2.3% (n = 1) in the complete excision group. In the flow-restored subcohorts, those with restoration using prosthetic interposition grafts had the greatest reinfection rate at 57.1% (n = 4), and those with restoration using autogenous conduits did not experience reinfection (P = .033). CONCLUSIONS: Incomplete excision of infected arteriovenous prosthetic grafts was associated with a higher rate of reinfection compared with complete graft excision. Complete excision presents technical challenges but could provide superior source control in managing infected dialysis access. Complete excision with vascular reconstruction should be performed when possible to avoid leaving remnant prosthetic material.
