OBJECTIVE: An abdominal pseudocyst (APC) is a distal catheter site specific failure in patients treated with ventriculoperitoneal shunts and few studies with more than ten patients have been reported. The aim of this study was to analyze causes of peritoneal catheter revisions with special emphasis on revisions due to an APC. METHODS: Pediatric patients with first shunt operation between 1982 and 1992 were included and time, cause and modality of peritoneal catheter revision were retrospectively determined...

Anti-microbial host defence is dependent on the rapid recruitment of inflammatory cells to the site of infection, the elimination of invading pathogens, and the efficient resolution of inflammation so as to minimise damage to the host. The peritoneal cavity provides an easily accessible and physiologically relevant system where the delicate balance of these processes may be studied. Here, we describe murine models of peritoneal inflammation that enable studies of both competent anti-microbial immunity and inflammation associated tissue damage as a consequence of recurrent bacterial challenge...

Pneumococcal flavin reductase (FlaR) is known to be cell-wall associated and possess age dependent antigenicity in children. This study aimed at characterizing FlaR and elucidating its involvement in pneumococcal physiology and virulence. Bioinformatic analysis of FlaR sequence identified three-conserved cysteine residues, suggesting a transition metal-binding capacity. Recombinant FlaR (rFlaR) bound Fe2+ and exhibited FAD-dependent NADP-reductase activity, which increased in the presence of cysteine or excess Fe2+ and inhibited by divalent-chelating agents...

BACKGROUND: Gut dysbiosis associated with the use of proton-pump inhibitors (PPIs) has been found to lead to the occurrence of infectious and inflammatory adverse events. A longitudinal observational cohort study has demonstrated the heightened risk of death associated with PPI use. SUMMARY: We evaluated meta-analyses to determine the association between PPI use and infectious and inflammatory diseases. Meta-analyses showed that PPI use is a potential risk for the development of enteric infections caused by Clostridium difficile, as well as small intestinal bacterial overgrowth, spontaneous bacterial peritonitis, community-acquired pneumonia, hepatic encephalopathy, and adverse outcomes in inflammatory bowel disease...

Yong Lv, Guohong Han, Daiming Fan
Hepatic hydrothorax (HH) is a pleural effusion that develops in a patient with cirrhosis and portal hypertension in the absence of cardiopulmonary disease. Although the development of HH remains incompletely understood, the most acceptable explanation is that the pleural effusion is a result of a direct passage of ascitic fluid into the pleural cavity through a defect in the diaphragm due to the raised abdominal pressure and the negative pressure within the pleural space. Patients with HH can be asymptomatic or present with pulmonary symptoms such as shortness of breath, cough, hypoxemia, or respiratory failure associated with large pleural effusions...

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is a common complication among cirrhotic patients. Guidelines recommend third-generation cephalosporins (3GCs) as empiric antibiotic therapy (EAT) of SBP. Recently, a broad-spectrum EAT was shown to be more effective than cephalosporins in the treatment of nosocomial spontaneous bacterial peritonitis (N-SBP); however, the prevalence of 3GCs-resistant bacteria is high in the nosocomial setting and broad-spectrum EAT cannot be used in all cases of SBP...

BACKGROUND: Surgical site infection (SSI) is a frequent complication in dirty surgery, reaching rates of up to 40%. The incidence of SSI might be influenced by the suture used for closure of the abdominal fascia. Sutures coated with antibacterial substances may reduce the bacterial load in the incision. PATIENTS AND METHODS: A retrospective study of patients with intra-operative diagnosis of fecal peritonitis undergoing a laparotomy in three Spanish hospitals was performed...

BACKGROUND & AIMS: The innate immune system responds not only to bacterial signals, but also to non-infectious danger-associated molecular patterns that activate the NLRP3 inflammasome complex after tissue injury. Immune functions vary over the course of the day, but it is not clear whether these changes affect the activity of the NLRP3 inflammasome. We investigated whether the core clock component nuclear receptor subfamily 1 group D member 1 (NR1D1, also called Rev-erbα) regulates expression, activity of the NLRP3 inflammasome, and its signaling pathway...

Alarming increase of death due to S. aureus sepsis demands newer treatment strategies. Enhancement of antibiotic resistant S. aureus strains caused increased mortality. Only antibiotic treatment for Staphylococcal sepsis has been found insufficient to improve outcomes. In the innate immune response, phagocytosis mediated killing of pathogen and further triggering of intracellular signaling cascades by the PRRs culminates in the release of a variety of pro inflammatory cytokines, which orchestrate together in the early host response to infection...

BACKGROUND: Mesenterial and peritoneal inflammation represents a major clinical challenge regarding differential diagnosis. In this review article, a systematic overview of the most common causes such as autoimmune reaction, infarction with consecutive necrosis and infection caused by protozoa or bacteria is provided. RESULTS: The common clinical features of all inflammatory peritoneal and mesenterial diseases are the nonspecific abdominal symptoms. Even in radiological imaging an overlap of imaging features such as lymphadenopathy and nodular mesenteric structures is typical...

BACKGROUND&AIMS: Pattern recognition receptors (PRRs) have a key role in the innate host defense. Functional polymorphisms of various PRRs have been established to contribute to an increased susceptibility to spontaneous bacterial peritonitis (SBP). Their role in the development of cirrhosis-associated bacterial infections (BI), beyond SBP or progressive disease course related to pathological bacterial translocation (BT) remains unknown. METHODS: 349 patients with cirrhosis were genotyped for common NOD2 (R702W, G908R and L1007PfsinsC), TLR2 (-16934T>A), and TLR4 (D299G) variants...

Background: Patients with cirrhosis who develop Spontaneous Bacterial Peritonitis (SBP) suffer from cirrhotic cardiomyopathy which is characterized by impaired contractility in response to stress despite a relatively normal resting cardiac output. We hypothesized that electrocardiographic and echocardiographic information would help prognosticate patients developing SBP in addition to existing scoring systems. Methods: Cirrhotic patients admitted to Einstein Medical Center from 01/01/2005 to 6/30/2012 for SBP, and did not receive a transplant within one year, were included...
