Frequently Asked Questions

Why is there a charge for this material when so much information on the internet is free?

If you have carefully examined most sites that have some similarities to this one you will find one or more of the following major deficiences: 1) the quality of the images is poor or image file size is so large that it takes too long to download 2) while a number of cases are shown, the discussion section is markedly limited 3) the number of cases is limited and rarely updated. This site was developed by the Editor over a year and the plans are to continually update all aspects of the site. The subscription price is nominal compared to most medical journal subscriptions. The fee covers computer, design and administrative costs.

Is this Website nothing more than selected sections of Dr. Callen's textbook?

No! All of the teaching file cases and discussions are new material based upon summaries of the literature written and edited by the Editor.

Why not put the material on CD-ROM instead of the internet?

While CD-ROMs have their advantages, they also have disadvantages. Two major disadvantages are: the CD-ROM must be carried with the user from computer to computer and be accessible and the information can not be quickly and readily updated on a CD-ROM.

How often will the site be updated?

In-depth teaching file cases will be added throughout the year based upon new clinical material and images. New journal articles will be added on a weekly basis as appropriate (Likely, between 5-10 articles each month)

My work has access to Melvyl, Medline or Healthline - why do I need to have this duplicated here?

The selected articles that are reviewed come from approximately 10 journals which often publish papers related to obstetrical and gynecological ultrasound. Medline etc just publishes the abstracts of some articles without commentary and often only after a delay of as much as 4 - 6 weeks. The articles which are reviewed by the Editor are not all articles published, but selected articles which are likely to have high reader interest. Most importantly it is difficult to ask Medline, etc to return all articles of importance relating to OB-Gyn ultrasound (when neither fetal, obstetrics, sonography, etc may have been indexed by them in the article).

Can I send in the images of an interesting or puzzling clinical case to the Bulletin Board section?

At the moment this capability is not available. Presently one can describe the findings and other readers of the bulletin board can answer with their own experience.

Are there plans to have CME credit?

Not at the present time.

Can I download the material to my computer for review offline?

There are numerous methods and programs available to allow you to do this. In some instances this may be quite helpful. As long as the material is utilized by the subscriber for his or her benefit only, there is no problem in doing this. Images of material may not be displayed or shared without consent of the publisher. Limited security methods will be used ito ensure that the site is not being inappropriately utilized. If you find this site useful and allow others to share passwords etc then it will ultimately be self-defeating. If there are not enough paying subscribers the journal cannot continue to exist.

Which hardware or software do I need to optimize my viewing of this site.

If you are reading this you already have what you will need to view the site. Basically, a Macintosh or Windows PC computer with the ability to make an internet connection will be fine. You can use whichever internet browser you are most familiar with. The faster the modem or internet connection, the faster the images will load. On a Macintosh computer, the display monitor control panel can be set to 16 bit (thousands of colors) and the images should appear fine. On a Windows PC computer, because the windows system and browser set aside colors only for their use, one needs to increase the settings in the display monitor control panel to optimize image quality. Viewing the images in either 16 bit (thousands of colors) or 24 bit "true color" (millions of colors) will improve the image quality.
