17 Clinical Trials for Various Conditions
Propionibacterium acnes is the most common pathogen identified from a surgical site infection in the shoulder. Standard skin preps do not prevent this type of infection. Patients will undergo either a chlorhexidine or benzoyl peroxide prep in days leading up to surgery. Bacterial burden will be determined at the time of surgery.
Bacteria is occasionally present in the shoulder during shoulder arthroplasty surgery and is hypothesized to increase the risk of failure of the prosthesis. Surgiphor (sterile Povidone-Iodine) wound irrigation, is a solution used in orthopaedic surgery and other surgical fields to kill bacteria intraoperatively. The Iodine dissociates from complex and has antimicrobial properties, causing cell death of bacteria, fungi, and viruses through interactions with proteins, nucleotides, and fatty acids in the cytoplasm and cytoplasmic membrane. This study examines the use of Povidone-Iodine during primary shoulder arthroplasty.
Despite the use of a standard preoperative skin disinfectant prior to shoulder surgery propionibacterium acne remains a leading cause of post-operative infections. The purpose of this study is to evaluate effectiveness of topical benzoyl peroxide as an adjuvant to chlorhexidine-impregnated skin preparation in attempting to lower the colonization propionibacterium acne prior to surgery. This study will take cultures from patients who are randomly assigned into groups that receive and do not receive benzoyl peroxide as additional skin prep prior to elective shoulder surgery and compare quantified culture results.
Differentiating between septic arthritis and other causes of joint inflammation in pediatric patients is challenging and of the utmost importance because septic arthritis requires surgical debridement as part of the treatment regimen. The current gold standard to diagnose septic arthritis in children is a positive synovial fluid culture; however, joint cultures may take several days to return. If a bacterial infection is present, it requires immediate surgical intervention in order to prevent lasting articular cartilage damage. Frequently surgeons must decide whether to surgically debride a joint before culture results are available. There is no single lab test or clinical feature that reliably indicates bacterial infection over other causes of joint inflammation. The alpha-defensin assay has shown high sensitivity and specificity for joint infection in other studies.The purpose of this study is to determine the sensitivity and specificity of several synovial biomarkers for diagnosing pediatric septic arthritis.
The goal of this interventional study is to determine the amount of skin C. acnes reduction with increased pressure during the chlorhexidine gluconate, brand name ChloraPrep, application. The main question it aims to answer is: Does changing the pressure applied during the ChloraPrep application impact the amount of C. acnes bacteria on the skin after one hour? Researchers will compare ChloraPrep applied at a pressure similar to a gentle wipe to ChloraPrep applied at a pressure similar to a massage to see if wash the amount of C. acnes on the skin after one hour is different. Participants will have one shoulder washed with ChloraPrep using pressure meant to impact the dermal layer, similar to a gentle wipe, and the other shoulder washed with ChloraPrep using pressure meant to impact the subdermal layer, similar to a massage. Participants will have swabs taken of their skin before the ChloraPrep application and again one hour after application to look for the amount of C. acnes on the skin.
Comparing the growth of intra-operative tissue cultures of Cutibacterium Acnes after primary shoulder replacement when using a no-prep control group versus antimicrobial wound gel versus betadine applied to the skin layer after the skin incision has been made. Reducing the bacteria present in the deep tissues at the end of the surgery may prevent infections from developing in the future.
The objective of this study is to collect and evaluate long-term clinical and radiographic outcomes data in order to better understand the safety and performance of the shoulder arthroplasty over time. This study will follow subjects long-term for a minimum of 10-years, without an early-term restriction on the amount of time they will be followed.
This is a prospective, randomized controlled trial to evaluation the ability of 5-aminolevulinic acid HCL topical solution photodynamic therapy to decrease the colonization of Cutibacterium acnes (C. acnes- a bacteria commonly found in the dermis of the skin surrounding the shoulder) in order to decrease postoperative joint infections. -Aminolevulinic acid (ALA) is a naturally occurring metabolite in the synthesis of pathway of cellular heme production. Adding ALA to bacteria encourages porphyrin production which serve as the immediate precursors to heme production. When these porphyrins are illuminated with blue light at an emission peak of 407-420nm, these metabolites become exothermic and cause internal destruction of the bacterial cells. This therapy does not cause any damage to the mammalian cells, which makes PDT safe for human skin treatment.
Cutibacterium acnes (C. acnes) is an anaerobic aerotolerant bacteria commonly isolated during revision shoulder surgery. It is increasingly recognized as a pathogen, mainly in implant-related infections. As an anaerobe, it usually needs a prolonged culture incubation time of up to 14 days for growth and the association between implant surgery and C. acnes infection is not always obvious. Unfortunately, prolonged incubation also increases the risk of false positive cultures in isolating organisms that may exist as a result of contamination. Given high rates of positive C. acnes cultures in cases of both primary and revision shoulder surgery, the ramifications of positive C. acnes cultures for clinical decision making remains uncertain. The purpose of this study is to prospectively study the efficacy and side-effect profile of surgical treatment plus an oral antibiotic regiment for shoulder PJI with indolent organisms (C. acnes and CNS).
Periprosthetic infection following shoulder arthroplasty is a devastating complication. Diagnosing and treating periprosthetic shoulder infection poses a significant challenge. At the forefront of this issue is Cutibacterium acnes because the current prophylactic regimens are insufficient to eradicate C acnes from the surgical field. It is believed that C acnes infections occur during surgery when the sebaceous glands in the skin are cut and exposed, leading to C acnes contaminating the surgeon's instruments and gloves and, thus, the surgical wound. The purpose of this study is to examine if making skin incisions using electrocautery will result in decreased C acnes contamination during shoulder arthroplasty. To this end, we propose a randomized clinical trial where patients undergoing shoulder arthroplasty are randomized into two groups - Electrocautery incision group (Electro) vs. Scalpel incision group (Scalpel) - and swab cultures are obtained from the skin incision and operating surgeon's gloves and forceps
This is a prospective, randomized controlled trial to evaluate the ability of hydrogen peroxide preparation in addition to chlorhexidine to decrease the colonization of Propionibacterium acnes(a bacteria commonly found in the dermis of the skin surrounding the shoulder in order to decrease postoperative joint infection.
Deep periprosthetic infection following total joint arthroplasty is a major complication. Although it only occurs in a small percentage of patients (\~1%), it results in substantial morbidity and a decline in functional outcome. A two stage revision and exchange is commonly required in order to clear the infection and provide the best opportunity for prosthetic replantation. Following removal of the infected components, a minimum course of six weeks of parenteral antibiotics is given and resolution of the infection confirmed through the ESR, CRP, and repeated aspiration of the joint. In most instances a temporary spacer of antibiotic-loaded cement is inserted at the first stage and removed at the second operation. Propionibacterium Acnes is a gram-positive, non-spore-forming, anaerobic bacillus found in lipid-rich areas, including hair follicles, sebaceous glands, and moist areas of the shoulder and axilla. Because of its low virulence, infections caused by P. acnes typically have a low-grade, indolent course, with shoulder pain often the only presenting symptoms after prosthetic replacement. P. acnes is particularly challenging to both diagnose and to eradicate, and is a substantial source of morbidity with shoulder arthroplasty. JumpStart™ is a wireless, advanced microcurrent generating, dressing used for the management of surgical incision sites. Microcell batteries made of silver and zinc, generate an electrical current when activated by conductive fluids, such as saline, hydrogel or wound exudate. These microcells create low voltage electrical fields to stimulate the surrounding area and to provide antimicrobial protection to assist with wound healing. JumpStart has demonstrated superior broad spectrum bactericidal activity of a wound dressing against antibiotic-resistant strains of wound isolates within 24 hours. The use of JumpStart as a prophylactic preoperative dressing to alter the skin flora and thereby decrease the risk of prosthetic infection has not been investigated to-date. Given the morbidity of a prosthetic infection, this would be a remarkably valuable intervention for any joint replacement procedure.
This study will evaluate the safety and effectiveness of daptomycin, an antibiotic compared to another one which is vancomycin when given around the time of joint replacement surgery. Vancomycin is recommended for perioperative prophylaxis in methicillin resistant Staphylococcus aureus (MRSA) colonized patients undergoing primary total joint arthroplasty. Daptomycin has not been recommended for this indication but it is FDA approved for treatment of MRSA blood stream and skin and soft tissue infections. Data collected during this study may support the use of daptomycin for this indication and may also be used for other research purposes that have not yet been specified.
We intend to determine how effective the use of a 2% Chlorhexidine Cloth is in terms of eliminating the bacterial load on patients undergoing shoulder surgery. We will be comparing the Chlorhexidine Cloths with a control group which will be performing an ordinary shower prior to surgery. At this time, it is standard of care to only take an ordinary shower the evening prior, and the morning of surgery.
The goal of this prospective randomized clinical trial is to investigate the potential synergistic effect of combination of topical benzoyl peroxide and making skin incision with electrocautery on preventing surgical wound contamination from Cutibacterium acnes (C. acnes) in patients undergoing shoulder replacement. The main question it aims to answer is: • Will the combined use of topical application of benzoyl peroxide and making skin incision using electrocautery decrease the positive culture rates of C. acnes in the surgical field? Participants will be asked to apply topical benzoyl peroxide to the shoulder skin prior to their shoulder replacement surgery if they are randomized in the treatment group. The skin incision will be made using electrocautery in both the control and treatment groups. Microbiology swab cultures will be taken during shoulder replacement surgery to compare the positive culture rates for C. acnes between the groups.
This study is about preventing surgical site infections of the shoulder. We hope to learn if clindamycin alone, benzoyl peroxide alone, or clindamycin and benzoyl peroxide together can affect growth of Propionibacterium acnes in the dermal layer.
