Web 2.0 and Medicine

Interesting article by Dean Giustini in BMJ
How Web 2.0 is changing medicine, BMJ 2006; 333: 1283-1284
[Full text]

"Few concepts in information technology create more confusion than Web 2.0. The truth is that Web 2.0 is a difficult term to define, even for web experts. Nebulous phrases like "the web as platform" and "architecture of participation" are often used to describe Web 2.0. Medical librarians suggest that rather than intrinsic benefits of the platform itself, it's the spirit of open sharing and collaboration that is paramount. The more we use, share, and exchange information on the web in a continual loop of analysis and refinement, the more open and creative the platform becomes; hence, the more useful it is in our work."

DICOM email

Standardization of teleradiology using Dicom e-mail: recommendations of the German Radiology Society.

Saw this article in "European Radiology" Dicom email looks like a revolutionary idea..

Reference-Eur Radiol 2006 Mar;16(3):753-8. Epub 2005 Oct 15.

"Until recently there has been no standard for an interoperable and manufacturer-independent protocol for secure teleradiology connections. This was one of the main reasons for the limited use of teleradiology in Germany. Various teleradiology solutions have been developed in the past, but the vast majority have not been interoperable. Therefore an ad hoc teleradiology connection was impossible even between partners who were already equipped with teleradiology workstations. Based on the evaluation of vendor-independent protocols in recent years the IT Working Group (AGIT) of the German Radiology Society set up an initiative to standardize basic teleradiology. An e-mail based solution using the Dicom standard for e-mail attachments with additional encryption according to the OpenPGP standard was found to be the common denominator. This protocol is easy to implement and safe for personalized patient data and fulfills the legal requirements for teleradiology in Germany and other countries. The first version of the recommendation was presented at the 85th German Radiology Convention in 2004. Eight commercial and three open-source implementations of the protocol are currently available; the protocol is in daily use in over 50 hospitals and institutions."

Bias in Medical Research

Why Most Published Research Findings Are False
John P. A. Ioannidis
Full Article at-Citation: Ioannidis JPA (2005) Why Most Published Research Findings Are False. PLoS Med 2(8): e124 DOI: 10.1371/journal.pmed.0020124
"There is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance. Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias."

"One Image Says it all contest" has announced a very interesting contest on his site. It goes like-

"Welcome to the first radiologic image contest. We are looking for the best single-image radiologic case. This contest is open to all visitors, and is completely free to enter" and Guess what the winner will get??-

Radiology Image search-Geat link to find Peer Reviewed Images

"Gold Miner speeds your search for radiology images by quickly matching search criteria with peer-reviewed content available on the Web. By limiting results to images from respected, peer-reviewed journals, you won’t waste time sifting through thousands of unrelated images or images from unknown sources. You can save more time by filtering for imaging modality, patient age and gender. GoldMiner is a service of the American Roentgen Ray Society"

Radiology Search Engine is a search engine for searching radiology peer-reviewed information from AJNR, AJR, Anatomy Atlases, BJR, eMedicine, EURORAD, Gray's Anatomy, Medcyclopaedia, Radiographics, and Radiology.Specifically, radiologists seeking answers to questions at the point- of-care may use as a decision support tool for searching radiology peer-reviewed information to improve patients' care, outcomes and is powered by the Google Custom Search Engine. A commendable effort by-Michael P. D'Alessandro, M.D.Professor of Radiology,University of Iowa College of Medicine.

CT for Gallstones

"An anthropomorphic phantom was scanned with or without gallstones at CT by using 80, 100, 120, and 140 kVp. The sensitivity for gallstone detection was significantly higher at 140 kVp than at lower voltage settings, regardless of gallstone size. CT attenuation measurements were not useful for determination of gallstone composition. Abdominal CT performed at 140 kVp may be useful when gallstone disease is of clinical concern. "

Wal-Mart, Intel, Others To Create Massive Health Records Database

"As the cost of providing health care continues to rise, Applied Materials, BP America, Inc., Intel Corporation, Pitney Bowes, Inc. and Wal-Mart are funding an independent nonprofit institute to develop “Dossia,” a Web-based framework through which U.S. employees, dependents and retirees can maintain lifelong personal health records. “Dossia will empower individuals to manage their own health care, improve communications with their doctors, and ensure more complete and accurate information for health care providers than the current fragmented, paper-based system,” said JD Kleinke, chairman and CEO of the Omnimedix Institute, the non-profit organization with headquarters in Portland, Ore. that is developing Dossia. “With Dossia’s personal, private and portable personal health records, individuals will be able to maintain comprehensive, up-to-date histories for themselves and their families.” The unique Dossia framework gathers health information on behalf of the individual from various sources and stores it within secured databases. Dossia’s open architecture will support multiple personal health applications, allowing users to organize and summarize their information in ways that are most useful to them. Health records will be secure and private, accessible only by the individual or by others to whom they have granted permission. Records also will be portable, enabling individuals to continue using the records even if they change employers, health plans or doctors."

256 Slice CT-Whole Heart Imaging In One Beat

256-slice CT shows promise in one-beat, whole-heart imaging.
"The patient cohort was small, but results were nonetheless described as "promising" in a study that assessed the feasibility of using a 256-slice CT scanner for the simultaneous assessment of coronary artery and cardiac function in one-beat, whole-heart studies.Because a 256-detector-row CT scanner covers 12.8 cm along the z-axis, one scan covers the whole heart with one 0.5-second rotation. Acquisition time was 1.5 seconds at 0.5-mm slice thickness, with radiation exposure of 14.2 mSv."

Milk as an Oral Contrast in CT

"Undergoing a scan of one's intestines isn't a pleasant experience for patients with conditions like Crohn's disease, especially since it means downing a concoction made with barium. But a new study suggests there may be a more palatable alternative: milk. Researchers found that milk coats the intestines well enough so that radiologists can properly view the organ in a CT scan. However, milk may not be ideal for all patients, especially since it seems to produce images that are less precise."

Milk May Be Pleasant Alternative for CT Scans It offers slightly poorer images but is more palatable than standard contrast agents, study finds.
