Introduction

Objectives

Welcome! This tutorial is designed to help you improve your PubMed searching skills.

It covers:

  • entering basic searches;
  • revising searches to find more of the relevant literature;
  • focusing search results using Limits;
  • selecting and downloading PubMed article references
  • finding the complete article online or in print

What is PubMed?

PubMed is a free web based interface for searching MEDLINE
  • Created by the National Library of Medicine
  • Covering medicine, nursing, dentistry, veterinary medicine, the health care system, and preclinical sciences
  • Containing information about articles, many with detailed abstracts, from 4,600 journals in 30 languages (does not include information about meeting abstracts, conference proceedings, dissertations, patents, or websites)
  • Using Medical Subject Headings (MeSH) index terms
  • Dating back to 1950 with the inclusion of OLDMEDLINE
  • Linking to some electronic full-text at publishers's websites

Connect to PubMed

UNC-CH Students, faculty and staff should connect through a UNC-CH website in order see links to UNC Full Text Online.

Detailed abstract

BACKGROUND: Aphthous ulcers are common and painful. Current treatments are palliative and focused on pain reduction. This article reports on the clinical trials of a novel, bioadhesive treatment modality. METHODS: Formulations of 2-octyl cyanoacrylate, or 2-OCA, tissue adhesive were tested in two blinded, sham-controlled studies. A total of 200 patients with a single, painful aphthous ulcer were entered. In the first study, the investigators applied the tissue adhesive to the aphthous ulcers; in the second trial, the subjects themselves applied the tissue adhesive to their ulcers. The authors evaluated the safety, pain reduction and healing times associated with the bioadhesive. RESULTS: The bioadhesives were found to be safe with no significant adverse events. The short- and long-term pain reduction achieved with an investigator-applied adhesive was significant compared with that achieved with a sham device (P = .024 and P = .036, respectively). The investigator-applied adhesive also demonstrated a significant reduction in healing time over the sham device (P = .021). In the definitive trial, in which the subjects themselves applied the tissue adhesive, pain reduction with a predicate device approved by the U.S. Food and Drug Administration and with the bioadhesive was significantly better than with a sham application (P < .05). The active devices were not statistically different from each other (P = .37). No difference in healing time was evident between devices and the sham. CONCLUSIONS: The formulations of 2-OCA tissue adhesives tested were safe and demonstrated statistically significant pain reduction when applied by either the investigators or the subjects. CLINICAL IMPLICATIONS: Our clinical trials indicate that these novel tissue adhesives could be used as nonprescription, over-the-counter devices to provide significant pain relief for patients suffering from aphthous ulcers.
