PURPOSE: After cleft lip and palate surgical procedures, patients often need nostril supports to help the reconstructed nostrils retain their shape during healing. Many postoperative nasal stents use a one-size-fits-all approach, in which a standard rubber tube retainer is trimmed and used to support the healing nares. The purpose of this study was to examine photogrammetry and 3-dimensional (3D) printing as a fabrication tool for postoperative patient-specific nasal supports that can be loaded with bioactive agents for localized delivery...

Irreversible electroporation (IRE) damages cell membranes and is used in medicine for non-thermal ablation of malignant tumors. Our aim was to evaluate the antimicrobial effect of IRE. The pathogenic microorganisms, S. aureus, S. pyogenes, E. coli, P. aeruginosa and C. albicans were subjected to IRE. Survival was measured as a function of voltage and the number of pulses applied. Combined use of IRE and oxacillin for eradication of S. aureus was also tested. Log10 reduction of microorganisms positively correlated with the number of applied pulses...

BACKGROUND: Commonly prescribed durations of therapy for many, if not most, bacterial infections are not evidence-based. Misunderstandings by clinicians and patients alike influence perspectives on antibiotic use, including duration of therapy and its role in antibiotic resistance. OBJECTIVE: To demonstrate that shorter durations of antibiotic therapy are as efficacious as longer durations for many infections. DATA SOURCES: A systematic review of English language articles using PubMed were identified for inclusion...

BACKGROUND: Penicillin allergy is commonly reported in the pediatric emergency department. We previously performed 3-tier penicillin allergy testing on children with low-risk symptoms, and 100% tolerated a penicillin challenge without an allergic reaction. We hypothesized that no serious allergic reactions would occur after re-exposure to penicillin and that prescription practices would change after testing. METHODS: We performed a follow-up case series of 100 children whose test results were negative for penicillin allergy...

Acute appendicitis in children requires early surgery, and a short course of antibiotics active on Enterobacteriaceae and anaerobes. Although aminoglycoside-containing 3-drug regimen have been used successfully for decades, simpler regimens with similar efficacy are increasingly used. We aimed to evaluate the impact of a switch from the combination of cefotaxime, metronidazole, and gentamicin (regimen 1), to piperacillin-tazobactam (regimen 2), as first-line regimen for complicated acute appendicitis in children...

Gram negative anaerobic organisms are important pathogens in a range of clinical infections, and susceptibility testing is not commonly performed in the microbiology laboratory. We performed anaerobic susceptibility testing on 70 clinically relevant Gram negative anaerobes isolated from routine cultures in a busy diagnostic laboratory which were identified by MALDI-TOF mass spectrometry (MALDI-TOF MS). The susceptibility testing was performed by two methods: Sensititre trays (ThermoFisher Scientific) against 15 different antibiotics, and Etests (bioMérieux) against five clinically relevant antibiotics (metronidazole, piperacillin-tazobactam, amoxicillin-clavulanate, meropenem and clindamycin)...

BACKGROUND: The incidence of Clostridium difficile-associated diarrhoea (CDAD) in hospitalized children and adolescents has been increasing year-on-year. Paediatric CDAD represents a significant economic burden on healthcare systems. Probiotics are live organisms thought to improve the microbial balance of the host, counteract disturbances in intestinal flora, and reduce the risk of colonization by pathogenic bacteria. AIM: We conducted a cost-effectiveness analysis to assess the economy of probiotics for the prevention of CDAD in children and adolescents receiving antibiotics...

BACKGROUND: The dietary methylamines choline, carnitine, and phosphatidylcholine are used by the gut microbiota to produce a range of metabolites, including trimethylamine (TMA). However, little is known about the use of trimethylamine N-oxide (TMAO) by this consortium of microbes. RESULTS: A feeding study using deuterated TMAO in C57BL6/J mice demonstrated microbial conversion of TMAO to TMA, with uptake of TMA into the bloodstream and its conversion to TMAO. Microbial activity necessary to convert TMAO to TMA was suppressed in antibiotic-treated mice, with deuterated TMAO being taken up directly into the bloodstream...
