1 April 2022: Weekly Roundup #84


This is what’s new on PathologyOutlines.com:

1. New Editorial Board Member for Hematopathology

Dr. Anamarija Perry was recently appointed to our Editorial Board for Hematopathology. She is an Associate Professor of Pathology at the University of Michigan in Ann Arbor. She obtained her M.D. at the University of Zagreb School of Medicine in Zagreb, Croatia and then completed her Anatomic and Clinical Pathology residency at the University of Cincinnati, followed by a fellowship in Hematopathology at the University of Nebraska.

2. Whole Slide Images

We are planning to add the capability of hosting whole slide images (WSI), perhaps 50 – 100 per year, which would be under our control so we no longer have to rely on links that often break. For visitors, this means they could view the images with a standard browser without add-ons. For authors, this means they would upload the images directly or give us access so we could do it ourselves. It also means our staff, many with IT backgrounds, would handle the IT issues. Because of a limited budget, we cannot go with the standard solutions, which cost $25K – $100K.

Please contact Nat@PathologyOutlines.com if you work with WSI and are willing to share some of your server and IT capabilities with us – we can discuss the terms. We are also open to other possible solutions.

The website is not actually down – this is some complicated internal struggle in the network.
