BACKGROUND: Complicated diverticulitis (CD) is a common problem for surgeons. In treating it, as a general principle, every verified source of infection should be controlled. Supplementary antimicrobial management involves a delicate balance of optimizing empirical therapy while reducing unnecessary antibiotic use. The necessity to know the most frequent infecting pathogens and their spectra of resistance is becoming pivotal. The aim of this study was to determine the microbiologic profile of complicated intra-abdominal infections (IAIs) secondary to CD, to analyze the role of empirical antimicrobial therapy, and to describe the clinical aspects of CD worldwide...

BACKGROUND/PURPOSE: Multidrug-resistant strains of Citrobacter have emerged, which carry Amp-C β-lactamase (Amp-C), broad-spectrum β-lactamase, extended-spectrum β-lactamase (ESBL), and other resistance mechanisms. These strains are associated with a higher rate of in-hospital mortality. The object of this study is to determine the mortality risk factors, susceptibility pattern to antibiotics, and prevalence of resistance genes in patients with Citrobacter freundii bacteremia. METHODS: From January 2009 to December 2014, blood isolates of C...

BACKGROUND: Appendectomy intra-abdominal is the most frequently performed emergency surgery. This study was conducted to determine the role of postoperative antibiotics in reducing surgical site infections (SSIs) and abscess formation after open appendectomy. METHODS: In the Department of Surgery, Shahid Beheshti Hospital, Babol, Iran, from October 2013 to October 2014 one hundred and fifty two patients, who underwent appendectomy for nonperforated appendicitis (NPA) and fulfilled the selection criteria, were randomized into two groups...

Bacteroides fragilis, a human pathogen, helps in the formation of intra-abdominal abscesses and is involved in 90% of anaerobic peritoneal infections. Phosphonopyruvate decarboxylase (PnPDC), a thiamin diphosphate (ThDP)-dependent enzyme, plays a key role in the formation of 2-aminoethylphosphonate, a component of the cell wall of B. fragilis. As such PnPDC is a possible target for therapeutic intervention in this, and other phosphonate producing organisms. However, the enzyme is of more general interest as it appears to be an evolutionary forerunner to the decarboxylase family of ThDP-dependent enzymes...

INTRODUCTION: Desmoid tumors are locally destructive but histologically benign. Their management involves close observation and surgical, medical, or hormonal treatment. PRESENTATION OF THE CASE: A 36-year-old male was admitted for abdominal pain and fever. A CT scan showed fluid collections and air within a mesenteric mass. Diagnostic laparotomy was performed with drainage of the abscess and biopsy of the mass. The pathology suggested a desmoid tumor. His fever and abdominal pain persisted...

BACKGROUND: Recent studies have suggested the length of treatment of intra-abdominal infections (IAIs) can be shortened without detrimental effects on patient outcomes. However, data from high-risk patient populations are lacking. We hypothesized that patients at high risk for treatment failure will benefit from a longer course of antimicrobial therapy. METHODS: Patients enrolled in the Study to Optimize Peritoneal Infection Therapy (STOP-IT) trial were evaluated retrospectively to identify risk factors associated with treatment failure, which was defined as the composite outcome of recurrent IAI, surgical site infection, or death...

BACKGROUND: Prolonging post-operative antibiotic treatment beyond 3 days does not seem to reduce the incidence of post-operative abscess formation or wound infection after surgery for complicated appendicitis. The route of administration seems to be based on an empirical basis. Using enteral antibiotics could reduce length of stay and reduce overall costs. We aimed to examine whether treatment with enteral antibiotics during the first three post-operative days is non-inferior to intravenous antibiotics regarding intra-abdominal abscess formation or wound infection after surgery for complicated appendicitis...

The genus Kluyvera comprises potential pathogens that can cause many infections. This study reports a Kluyvera intermedia strain (FOSA7093) from a pancreatic cyst specimen from a long-term hospitalised patient. Whole-genome sequencing (WGS) of the K. intermedia isolate was performed and the strain was reported as sensitive to Danish-registered antibiotics although it had a fosA-like gene in the genome. There were nine contigs that aligned to a plasmid, and these contigs contained several heavy metal resistance gene homologues...

INTRODUCTION: Intra-abdominal infections are the second most frequent cause of sepsis. In a recent cohort, fungal specimens were found in 51.9% of all patients with sepsis and peritonitis. Current systematic reviews comparing untargeted antifungal treatment with placebo or no treatment in patients who are critically ill have provided conflicting results, and clinical equipoise exists. Accordingly, we aim to assess patient-important benefits and harms of untargeted antifungal therapy versus placebo or no treatment in adult patients with complicated intra-abdominal infection...

AIMS: An increase in the prevalence of antimicrobial resistance among gram-negative pathogens has been noted recently. A challenge in empiric treatment of complicated intra-abdominal infection (cIAI) is identifying initial appropriate antibiotic therapy, which is associated with reduced length of stay and mortality compared with inappropriate therapy. The objective of this study was to assess the cost-effectiveness of ceftolozane/tazobactam + metronidazole compared with piperacillin/tazobactam (commonly used in this indication) in the treatment of patients with cIAI in UK hospitals...

Left ventricular assist device (LVAD) is one of the modern management therapies in patients with advanced heart failure, and it serves as a bridge to heart transplantation or even as destination therapy. However, it is burdened with a high risk of thromboembolic, hemorrhagic, and infectious complications despite prophylactic management. Splenic abscesses, as septic complications following implantation of mechanical ventricular support, have not yet been described in the literature. We report of a patient with severe left ventricular insufficiency (NYHA II/III), pulmonary hypertension, and arrhythmia who underwent implantation of the Heart Ware® pump for left ventricular support with simultaneous tricuspidvalvoplasty, as a bridge therapy to heart transplantation...

INTRODUCTION: Urinary tract infections (UTI) are a major public health problem among spinal cord injury (SCI) patients. They frequently involve multidrug-resistant (MDR) bacteria. Ceftolozane/tazobactam (C/T) is a novel antibiotic combination approved for complicated intra-abdominal and UTI caused by Gram-positive and Gram-negative organisms, including some MDR strains. Little is known about the use of this agent for complicated febrile UTI occurring among SCI patients with neurogenic bladder due to MDR Pseudomonas aeruginosa (PSA)...

INTRODUCTION: Surgical site infections (SSIs) and especially organ/space infection (O/SI) after resection or ablation of liver tumors are associated with increased morbidity and mortality. A secondary blood stream infection (BSI) is considered an O/SI but the exact prevalence is unknown. We aimed to investigate the incidence of O/SI and BSIs in a cohort of consecutive patients after liver resection or ablation, to seek for a possible connection between them and to search for potential risk factors...

INTRODUCTION: A 71 year old Peruvian woman presented with blurry vision and bilateral eye pain and had evidence of bilateral endophthalmitis on eye examination. Her past medical history was notable for multiple abdominal surgeries within the preceding months, including an incarcerated inguinal hernia repair which required an ileostomy placement, and cholecystitis requiring cholecystostomy tube placement. Over her multiple long hospitalizations, she developed bacteremia and fungemia on several occasions, with organisms including Enterobacter cloacae, Klebsiella pneumoniae, Bacteroides fragilis, Pseudomonas aeruginosa, Enterococcus faecium, and Candida albicans...

In Denmark, the incidence of carbapenemase-producing organisms (CPO) is increasing, and a coordinated national strategy is needed. We describe a case story of a 40-year-old woman transferred to a Danish hospital with severe complications after cosmetic surgery in the Middle East. She had an intra-abdominal infection with three different CPO, one of them co-resistant to colistin, one of the few remaining antibiotics for CPO treatment. Because of good clinical response to surgical treatment, antibiotics covering these multiresistant bacteria were not given...

BACKGROUND: Intra-abdominal infections represent a subgroup of septic syndromes with high death rates and the need for prompt and appropriate antimicrobial therapy. Conventional culture-based microbial identification has notable shortcomings in the diagnostics of polymicrobial infections. Modern culture-independent molecular methods may represent a new diagnostic approach. The current study aimed to compare the results obtained from the denaturing high-performance liquid chromatography WAVE(®) system as a culture-independent diagnostic tool with those obtained from standard culture-based microbiologic testing in the clinical setting of severe intra-abdominal sepsis...
