Cathodic voltage-controlled electrical stimulation and betadine decontaminate nosocomial pathogens from implant surfaces.

Periprosthetic joint infection (PJI) after total joint arthroplasty is a major concern requiring multiple surgeries and antibiotic interventions. , , and are the predominant causes of these infections. Due to biofilm formation, antibiotic treatment for patients with PJI can prolong resistance, further complicating the use of current treatments.

Neutralization of high pH and alkalinity effluent from recycled concrete aggregate by common subgrade soil.

Use of recycled concrete aggregate (RCA) as highway basecourse material conserves virgin aggregate, reduces energy consumption and CO emissions, and may also decrease costs during construction. However, concerns remain over possible negative environmental impacts associated with high pH (>11) effluent from RCA in contact with water. This study examines the reactive transport of high-pH and high-alkalinity water, modeled on RCA leachate, through model subgrade soils.

Continuous femoral nerve analgesia after unilateral total knee arthroplasty: stimulating versus nonstimulating catheters.

Background: Continuous femoral analgesia provides extended pain relief and improved functional recovery for total knee arthroplasty (TKA). Stimulating catheters may allow more accurate placement of catheters.

Methods: We performed a randomized prospective study to investigate the use of stimulating catheters versus nonstimulating catheters in 41 patients undergoing TKA.

Optimizing postoperative pain management.

The quality of postoperative pain management can be improved. Although many safe and effective therapies exist, their utilization varies considerably between and within institutions. Major challenges include the appropriate prescribing of analgesic therapies and the timely response to suboptimal pain control.

Hetastarch allergy and positive latex radioallergosorbent test in a patient suffering cardiovascular decompensation during multiple perioperative periods.

The cause of sudden cardiovascular collapse in the perioperative period can be elusive. Allergy may be overlooked as a cause. When allergy is considered, latex is often suspected.
