Evaluation of internet derived patient information for Acute Pancreatitis.

INTRODUCTION: Possibly In the UK there are currently over 26,000 patients admitted to hospital for acute pancreatitis per annum and the incidence is rising. 55% of patients consult the internet for information regarding their medical condition. As the number of people using the internet has increased 57% since 2006, it is increasingly important for medical professionals to direct patients to accurate online sources of information. This paper aims to evaluate the quality of information available online for acute pancreatitis. METHODS: The term 'acute pancreatitis' was searched using http://www.google.com, http://www.bing.com, and http://www.yahoo.com. The top 10 results of each of these websites were assessed using the University of Michigan consumer health website evaluation checklist. RESULTS: Of the 30 websites found, 4 were excluded from the evaluation. Within the 26 evaluated websites there was high variability in website quality. However, the authors would have used 18 of the websites again for the purpose of finding out information on acute pancreatitis. 15 websites had a named author of which 11 displayed their credentials. 8 of the websites had been updated within the last year. 10 websites displayed a bias or conflict of interest. Generally, the layout and design of websites was good, however 7 of the websites contained distracting graphics and 9 of the websites had no search facility. DISCUSSION: Doctors should give patients the information they want and need. With a high percentage of patients using the internet, medical professionals should recommend good quality websites to their patients. Engaging in this process could improve the consenting process as patients would be better informed. Good quality websites allows patients to explore conditions by themselves, with a re-consultation facilitating further discussion. Failure to engage in internet-based information risks patients making misinformed decisions due to bias and conflict of interest.

Removal of Dental Biofilms with an Ultrasonically Activated Water Stream.

Acidogenic bacteria within dental plaque biofilms are the causative agents of caries. Consequently, maintenance of a healthy oral environment with efficient biofilm removal strategies is important to limit caries, as well as halt progression to gingivitis and periodontitis. Recently, a novel cleaning device has been described using an ultrasonically activated stream (UAS) to generate a cavitation cloud of bubbles in a freely flowing water stream that has demonstrated the capacity to be effective at biofilm removal. In this study, UAS was evaluated for its ability to remove biofilms of the cariogenic pathogen Streptococcus mutans UA159, as well as Actinomyces naeslundii ATCC 12104 and Streptococcus oralis ATCC 9811, grown on machine-etched glass slides to generate a reproducible complex surface and artificial teeth from a typodont training model. Biofilm removal was assessed both visually and microscopically using high-speed videography, confocal scanning laser microscopy (CSLM), and scanning electron microscopy (SEM). Analysis by CSLM demonstrated a statistically significant 99.9% removal of S. mutans biofilms exposed to the UAS for 10 s, relative to both untreated control biofilms and biofilms exposed to the water stream alone without ultrasonic activation (P < 0.05). The water stream alone showed no statistically significant difference in removal compared with the untreated control (P = 0.24). High-speed videography demonstrated a rapid rate (151 mm(2) in 1 s) of biofilm removal. The UAS was also highly effective at S. mutans, A. naeslundii, and S. oralis biofilm removal from machine-etched glass and S. mutans from typodont surfaces with complex topography. Consequently, UAS technology represents a potentially effective method for biofilm removal and improved oral hygiene.
