Sensors able to record large bowel physiology and biochemistry in situ in awake rodents are lacking. Microdialysis is a mini-invasive technique that may be utilized to continuously deliver or recover low-molecular substances from various tissues. In this experiment we evaluated the feasibility of in vivo microdialysis to monitor extracellular fluid chemistry in the descending colon submucosa of conscious, freely moving rodents. Following surgical implantation of a microdialysis probe, male Wistar rats were housed in metabolic cages where they were analgized and clinically followed for four days with free access to standard diet and water...

This review is based on the author's Donald Munro Lecture given at the annual conference of the Academy of Spinal Cord Injury Professionals in New Orleans, LA. Indwelling catheters play an important role in bladder management following SCI for many individuals with neurogenic bladders. There is an increased risk of UTI compared to other types of bladder management with indwelling urethral catheters but not SP catheters. To minimize the risk of symptomatic UTI, the following steps are essential: prevent bladder wall distention and resulting ischemia, maintain colonization with "good" bacteria, and prevent bladder stones...

BACKGROUND: Intraluminal electrical impedance is a well-known diagnostic tool used to study bolus movement in the human esophagus. However, it is use in the human colon it is hindered by the fact that the content cannot be controlled and may include liquid, gas, solid, or a mixture of these at any one time. This article investigates the use of complex impedance spectroscopy to study different luminal content (liquid and gas). METHODS: An excised section of guinea pig proximal colon was placed in an organ bath with Krebs solution at 37°C and a custom built bioimpedance catheter was placed in the lumen...

Gram-positive bacteria, particularly Staphylococcus aureus is a significant pathogen, not only in the hospital setting but the community also. S. aureus is a major cause of serious hospital and community-acquired infections, particularly in the colonized individuals. The emergence of vancomycin-resistant S. aureus (VRSA) strains has led to global concerns about treatments for staphylococcal infections. Until now, few strains of VRSA have been reported worldwide. The conventional disk diffusion method for determination of vancomycin sensitivity often misclassifies intermediately susceptible isolates to fully sensitive...

Delayed bowel erosion by peritoneal dialysis catheter is rare with fewer than thirty cases having been reported in the literature. This complication is usually encountered when the catheter is kept dormant. Two cases have also been reported with catheters in active use. The risk factors for bowel erosion include immunosuppression, diverticulosis, and amyloidosis. An 80-year-old male with chronic kidney disease Stage 5 due to hypertensive nephrosclerosis underwent chronic ambulatory peritoneal dialysis catheter insertion...

Duodenal graft complications are poorly reported complications of pancreas transplantation that can result in graft loss. Excluding patients with early graft failure, after a median follow-up period of 126 months (range 23-198) duodenectomy was required in 14 of 312 pancreas transplants (4.5%). All patients were insulin-independent at the time of diagnosis. Reasons for duodenectomy included delayed duodenal graft perforation (n=10, 71.5%) and refractory duodenal graft bleeding (n=4, 28.5%). In patients with duodenal graft bleeding, a total duodenectomy was performed...

Candida parapsilosis is a major cause of hospital-acquired infection, often related to parenteral nutrition administered via catheters and hand colonization of health care workers, and its peculiar biofilm formation ability on plastic surfaces. The mortality rate of 30% points to the pressing need for new antifungal drugs. The present study aimed at analyzing the inhibitory activity of the N-terminal lactoferrin-derived peptide, further referred to as hLF 1-11, against biofilms produced by clinical isolates of C...

OBJECTIVES: Buccal mucosa grafts and fascio-cutaneous flaps are frequently used in long anterior urethral strictures (1). The inlay and onlay buccal mucosa grafts are easier to perform, do not need urethral mobilization and generally have good long-term results (2-4). In the present video, we present a case where we used a double buccal mucosa graft technique in a simultaneous penile and bulbar urethral stricture. MATERIALS AND METHODS: A 54 year-old male patient was submitted to appendectomy where a urethral catheter was used for two days in May 2015...

Central venous access devices play an important role in patients with prolonged intravenous administration requirements. In the last years, the coating of these devices with bactericidal compounds has emerged as a potential tool to prevent bacterial colonization. Our study describes the modification of 3D-printed reservoirs and silicone-based catheters, mimicking central venous access devices, through different approaches including their coating with the well known biocompatible and bactericidal polymer chitosan, with the anionic polysaccharide alginate; also, plasma treated surfaces were included in the study to promote polymer adhesion...

The use of Central Venous Catheters (CVCs) commonly results in complications. Coatings with silver or metal alloys can reduce the risk associated with the use of CVC. We have evaluated the durability of a noble metal coated CVC (the Bactiguard Infectious Protection, BIP CVC) and compared with an uncoated CVC for clinical tolerability (Adverse Events, AEs) and performance, in order to create a baseline for a large future study. Patients undergoing major surgery, randomised at a 2:1 ratio to BIP CVC (n = 22) or standard CVC (n = 12), were catheterized 9 - 12 days, respectively...
