Two-component systems (TCS) are modular signal transduction pathways that allow cells to adapt to prevailing environmental conditions by modifying cellular physiology. Staphylococcus aureus has 16 TCSs to adapt to the diverse microenvironments encountered during its life cycle, including host tissues and implanted medical devices. S. aureus is particularly prone to cause infections associated to medical devices, whose surfaces coated by serum proteins constitute a particular environment. Identification of the TCSs involved in the adaptation of S...

RATIONALE: Currently, the use of double-lumen irrigation-suction tube for drainage has become increasingly more common. However, the insertion process is complex, and the position of the double cannula placed in this manner is not accurate. We developed a method for placing the drainage tube and use it in the treatment of an abdominal infection. PATIENT CONCERNS: A 51-year-old man with an abdominal infection due to colonic anastomotic fistula was admitted. Routine laboratory tests revealed an elevated white blood cell count (17 × 10/L) and C-reactive protein level (78 mg/L)...

A lymphocele is one of the complications of systematic pelvic or para-aortic lymphadenectomy. Although most patients are entirely asymptomatic, our patient exhibited an obstructive ileus at the jejunum compressed by a lymphocele. We report here a case of a subsequent para-aortic lymphocele treated with autologous peripheral blood injection. A 68-year-old woman with sigmoid colon cancer (T3N2bM1a) underwent laparoscopic sigmoidectomy. After 4 courses of chemotherapy (CapeOX + Bmab), para-aortic lymphadenectomy was additionally performed...

OBJECTIVES: Although routine catheter tip cultures are not recommended, previous reports have indicated that some cases of colonization, such as with S. aureus, can lead to subsequent bacteremia. To evaluate the safety of colonized cases without antimicrobial treatment, as well as the effectiveness of routine catheter tip cultures in the neonatal intensive care unit (NICU), we performed a retrospective data analysis in a Japanese community hospital. METHODS: We reviewed all peripherally inserted central venous catheter tip culture results from the NICU ward between April 2012 and June 2017 to determine whether they had antimicrobial treatments or subsequent infections...

Mesenteric ischemia is a rare disorder, with considerably high morbidity and mortality rates. It can manifest in several ways, including acute mesenteric ischemia, chronic mesenteric ischemia, nonocclusive mesenteric ischemia, mesenteric venous thrombosis, and colonic ischemia. Of these, acute mesenteric ischemia is the most severe form of intestinal ischemia, with a high mortality rate. The mainstay of therapy for mesenteric ischemia is surgical exploration and resection of infarcted bowel; however, medical therapy can play an important adjunctive role...

Background: The experience with uretero-arterial fistulas has been limited. However, the aggressive treatment of pelvic tumors with surgical resection and radiotherapy, along with liberal use of ureteral catheters, has been attributed to an increase in their incidence. Unless they are promptly diagnosed and treated, uretero-arterial fistulas are associated with considerably high rates of morbidity and mortality. Urologists need maintain a high degree of suspicion for uretero-arterial fistula in high-risk patients...

Fungal catheter-related bloodstream infections (CRBSIs)-primarily due to Candida species-account for over 12% of all CRBSIs, and have been progressively increasing in prevalence. They present significant health and economic burdens, and high mortality rates. Antimicrobial catheter lock solutions are an important prophylactic option for preventing fungal CRBSIs. In this study, we compared the effectiveness of two FDA-approved catheter lock solutions (heparin and saline) and three experimental antimicrobial catheter lock solutions-30% citrate, taurolidine-citrate-heparin (TCH), and nitroglycerin-citrate-ethanol (NiCE)-in an in vitro model of catheters colonized by fungi...

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...
