Ying M Tang, Christian D Stone
The problem of Clostridium difficile infection (CDI) has reached epidemic proportions, particularly in industrialized nations. The pathophysiology, disease course and the potential complications are well appreciated in the general hospitalized patient. However, when CDI occurs in the setting of inflammatory bowel disease (IBD), a number of distinct differences in the diagnosis and clinical management of the infection in this population should be appreciated by gastroenterologists, hospitalists and other care providers...

BACKGROUND: Senecavirus A (SVA), a member of the family Picornaviridae, genus Senecavirus, is a recently identified single-stranded RNA virus closely related to members of the Cardiovirus genus. SVA was originally identified as a cell culture contaminant and was not associated with disease until 2007 when it was first observed in pigs with Idiopathic Vesicular Disease (IVD). Vesicular disease is sporadically observed in swine, is not debilitating, but is significant due to its resemblance to foreign animal diseases, such as foot-and-mouth disease (FMD), whose presence would be economically devastating to the United States...

The interactions of chemokines with their G protein-coupled receptors promote the migration of leukocytes during normal immune function and as a key aspect of the inflammatory response to tissue injury or infection. This review summarizes the major cellular and biochemical mechanisms by which the interactions of chemokines with chemokine receptors are regulated, including: selective and competitive binding interactions; genetic polymorphisms; mRNA splice variation; variation of expression, degradation and localization; down-regulation by atypical (decoy) receptors; interactions with cell-surface glycosaminoglycans; post-translational modifications; oligomerization; alternative signaling responses; and binding to natural or pharmacological inhibitors...

Cyprinid herpesvirus 1 (CyHV1) infects all scaled and color varieties of common carp Cyprinus carpio, including koi. While it is most often associated with unsightly growths known as 'carp pox,' the underlying lesion (epidermal hyperplasia) can arise from a variety of disease processes. CyHV1-induced epidermal hyperplasia may occur transiently in response to water temperature, and thus histopathology cannot be used in isolation to assess CyHV1 infection status. To address this problem, here we describe a PCR assay targeted to the putative thymidine kinase gene of CyHV1...

INTRODUCTION AND OBJECTIVE: Percutaneous nephrolithotomy (PCNL) is the gold standard treatment for kidney stones regardless of age. Elderly patients (EP)≥65years old, in growing numbers, have more comorbidities than the general population, may alter results of PCNL. The aim of this meta-analysis was to compare efficacy and complications of this procedure between EP and young patients (YP). METHODS: Original studies of prospective and historical cohorts, in English or French, presenting PCNL series published on PubMed until 2015 were identified using the keywords percutaneous nephrolithotomy, elderly patients, kidney stones and staghorn calculi...

Uveitic (or inflammatory) macular edema (UME) is one of the most common cause of visual impairment in patients with uveitis and the most frequent structural complication of uveitis. The use of antiangiogenic agents in the management of macular edema due to inflammation is a fairly new approach. It is not entirely clear if these agents should be used as an adjunct to anti-inflammatory therapy or if they can be used as stand-alone agents in edema due to infections where immunosuppressive therapy could be detrimental to the resolution of infection...

Background: A number of occupations and professions may be associated with unique hazards relevant to urologic care. Case Presentation: We relate the presentation, care, and the occupational hazard of urinary tract infection (UTI), presenting as cystitis and pyelonephritis, with stone formation in a scuba diver. The patient voiced concern that his diving suit malfunction was related to his UTI and stone disease. We review the risk of UTI in the diving environment. We also report the development of infection-related stone in this case...

REVIEW

Intrahepatic stone is prevalent in Asian countries; though the incidence declines in recent years, the number of patients is still in a large quantity. Because of multiple complications, high recurrence rates, serious systemic damage, and a lack of extremely effective procedure for the management, it is more important to find out the etiology and pathogenesis of intrahepatic stones to prevent the disease from happening and developing rather than curing. A number of factors contribute to the development of the disease, such as cholestasis, infection, and anatomic abnormity of bile duct and bile metabolic defect...

BACKGROUND: The treatment of periprosthetic joint infection is a difficult challenge in shoulder arthroplasty. This study investigated 1-stage modular component exchange vs. 1-stage complete removal and reimplantation (CRR) vs. 2-stage revision arthroplasty for periprosthetic joint infection. METHODS: Between January 1, 2004, and December 31, 2012, 79 patients received a component exchange (n = 15), CRR (n = 45), or a 2-stage (n = 19) revision for infection. A binary logistic regression analysis was performed to determine factors presenting the greatest risk of reinfection...

BACKGROUND: The recent Ebola outbreak in West Africa led to the use of a variety of different platform technologies for assaying antibodies because of the difficulties of handling the live virus. The same types of method could be applied rapidly to other infections when they emerge. There is a need to compare quantitative results of different assays, which means that the assays must measure similar parameters and give comparable results. METHODS: A collaborative study was carried out to establish an International Reference Reagent through WHO...

The importance of assessing perioperative urine/stone cultures and providing appropriate antibiotic prophylaxis prior to shock wave lithotripsy (SWL) or endoscopic intervention cannot be minimized. Urinary tract infection (UTI) is the most common complication relating to stone intervention. Adequate assessment of culture data and adherence to appropriate guidelines may prevent the development of UTI and the potential for post-intervention urosepsis. This review outlines the current evidence for prophylaxis in the prevention of UTI and urosepsis, as well as the interpretation of stone culture data to provide an evidence-based approach for the judicious use of antibiotics in urologic stone practice...

BACKGROUND: Infection is a common problem in Emergency Departments (ED) and is associated with high mortality, morbidity and costs. Identifying infection in ED patients can be challenging. Biomarkers can facilitate its diagnosis, enabling an early management and improving outcomes. In the critical care setting, two emerging biomarkers, pancreatic stone protein (PSP) and soluble CD25 (sCD25), have demonstrated to be useful for diagnosis of sepsis. We aimed to assess the diagnostic value of these biomarkers, in comparison to procalcitonin (PCT), for infection and sepsis in an ED population with suspected infection...

REVIEW
Brandee L Stone, Catherine A Brissette
The emerging pathogen, Borrelia miyamotoi, is a relapsing fever spirochete vectored by the same species of Ixodes ticks that carry the causative agents of Lyme disease in the US, Europe, and Asia. Symptoms caused by infection with B. miyamotoi are similar to a relapsing fever infection. However, B. miyamotoi has adapted to different vectors and reservoirs, which could result in unique physiology, including immune evasion mechanisms. Lyme Borrelia utilize a combination of Ixodes-produced inhibitors and native proteins [i...

Humans and chimpanzees are more sensitive to endotoxin than are mice or monkeys, but any underlying differences in inflammatory physiology have not been fully described or understood. We studied innate immune responses in Cmah(-/-) mice, emulating human loss of the gene encoding production of Neu5Gc, a major cell surface sialic acid. CMP-N-acetylneuraminic acid hydroxylase (CMAH) loss occurred ∼2-3 million years ago, after the common ancestor of humans and chimpanzees, perhaps contributing to speciation of the genus HomoCmah(-/-) mice manifested a decreased survival in endotoxemia following bacterial LPS injection...
