Raoultella ornithinolytica and Raoultella planticola are histamine-producing bacteria that are usually found in fish and water. They are associated with scombroid syndrome that presents with vomiting and flushing. A wide range of infections with these germs is reported, but mainly in fragile hospitalized patients with multiple comorbidities. We report the case of a 54-year-old healthy patient who presented with 24-hours abdominal pain, vomiting, flushing and shock. The abdominal examination showed guarding in the right lower quadrant (RLQ), and the abdominal CT scan images showed a thickened terminal ileum and a distended appendix...

In this study differences in the placental microbiota of term and preterm deliveries from a large UK pregnancy cohort were studied using 16S targeted amplicon sequencing. The impact of contamination from DNA extraction, PCR reagents, as well as those from delivery itself were also examined. A total of 400 placental samples from 256 singleton pregnancies were analysed and differences investigated between spontaneous preterm, non-spontaneous preterm, and term delivered placenta. DNA from recently delivered placenta was extracted, and screening for bacterial DNA was carried out using targeted sequencing of the 16S rRNA gene on the Illumina MiSeq platform...

OBJECTIVE: Peritoneal carcinomatosis (PC) is common in advanced tumor stages or disease recurrence arising from gastrointestinal cancers, gynecologic malignancies, or primary peritoneal carcinoma. Since current therapies are mostly ineffective, new thera-peutic approaches are needed. Here, we report on a phase I study designed to assess safety, MTD, and anti-tumor activity of intra-peri-toneal (i.p.) administration of oncolytic vaccinia virus GL-ONC1 in advanced stage PC patients. DESIGN: GL-ONC1 was administered i...

Antimicrobial resistance among Enterobacteriaceae has been increasing globally especially due to extended-spectrum-β-lactamases (ESBLs), which typically necessitate the use of carbapenems for treatment of serious infections. Emerging carbapenem-resistant Enterobacteriaceae further complicate therapy. As part of the Study for Monitoring Antimicrobial Resistance Trends (SMART), this analysis examined the recent activity of a key carbapenem (ertapenem) and other important therapeutic options against Enterobacteriaceae...

BACKGROUND: Appendectomy, the surgical removal of the appendix, is performed primarily for acute appendicitis. Patients who undergo appendectomy for complicated appendicitis, defined as gangrenous or perforated appendicitis, are more likely to suffer from postoperative complications. The routine use of abdominal drainage to reduce postoperative complications after appendectomy for complicated appendicitis is controversial.This is an update of the review first published in 2015. OBJECTIVES: To assess the safety and efficacy of abdominal drainage to prevent intra-peritoneal abscess after open appendectomy for complicated appendicitis...

Background: The emergence of antibiotic resistance among bacterial pathogens in the hospital and community has increased the concern to the health-care providers due to the limited treatment options. Surveillance of antimicrobial resistance (AMR) in frequently isolated bacterial pathogens causing severe infections is of great importance. The data generated will be useful for the clinicians to decide empiric therapy on the local epidemiological resistance profile of the antimicrobial agents...

Polymicrobial intra-abdominal infections (IAI) are a significant cause of morbidity and mortality, particularly when fungal pathogens are involved. Our experimental murine model of IAI involving intra-peritoneal inoculation of Candida albicans and Staphylococcus aureus results in synergistic lethality (∼80%) due to exacerbated inflammation. Monomicrobial infection results in no mortality despite similar microbial burden and dissemination as a co-infection. In the co-infection model, the immunomodulatory eicosanoid, prostaglandin E2 (PGE2 ) was determined to be necessary and sufficient to induce mortality implicating PGE2 as the central mediator of the amplified inflammatory response...

BACKGROUND: Acute appendicitis is one of the most common indications for emergency surgery. In patients with a complex appendicitis, prolonged antibiotic prophylaxis is recommended after appendectomy. There is no consensus regarding the optimum duration of antibiotics. Guidelines propose 3 to 7 days of treatment, but shorter courses may be as effective in the prevention of infectious complications. At the same time, the global issue of increasing antimicrobial resistance urges for optimization of antibiotic strategies...

BACKGROUND: Clinical practice guidelines recommend a 2-g dose of cefotetan and cefoxitin for surgical prophylaxis. Pharmacokinetic data suggest benefit from higher cefotetan and cefoxitin dosing in obese patients. However, clinical studies examining higher dosing strategies in this at-risk population are lacking. The purpose of this study was to determine whether 3 g of cefotetan or cefoxitin administered pre-operatively for patients who weigh 120 kg or more is associated with a lower proportion of surgical site infection (SSI) compared with 2 g...

BACKGROUND: In a previous study, we have shown that intermittent Pringle maneuver (IPM) might increase postoperative complications after hepatectomy for various indications. Complications which thought to be related to IPM were ascites, pleural effusion, wound infection and intra-abdominal collection. The aim of this study was to test the hypothesis that applying IPM during hepatectomy for hepatocellular carcinoma (HCC) could increase postoperative complications. METHODS: Between January 2013 and October 2016, eligible patients who received elective open hepatectomy for HCC were randomized to have IPM or no Pringle maneuver (NPM)...

Lactobacillus species colonize the human gastrointestinal tract and are rarely pathogenic. We present a case involving a cirrhotic patient who presented with sepsis and was found to have peritoneal cultures demonstrating Lactobacillus as the sole pathogen concerning for spontaneous bacterial peritonitis. Treatment was achieved with high-dose penicillin and clindamycin but the patient developed hepatorenal syndrome and died from acute renal failure. Intra-abdominal Lactobacillus infections are typically seen in patients undergoing peritoneal dialysis or who have recently had bowel perforation...
