Patient freed from choke hold of mysterious disease

Kristen Green and daughter Abby

Kristen Green was pregnant with her daughter Abby when she was diagnosed with a rare, life-threatening disease.

Physicians in Vail, Colorado, told Kristen Green that her shortness of breath was most likely caused by asthma or acid reflux. In fact, it was caused by a rare disease that was slowly closing off her airway.

After a frustrating three-year quest for relief, she ended up in the Intensive Care Unit at University of Colorado Hospital, where she was diagnosed with a condition known as ISS.

Her best chance for a cure was a complex and delicate surgery, but she was an expectant mother at the time, and her surgeons (our own Drs. Mitchell, Weyant, and Meguid) believed it was too dangerous for her to undergo the procedure while pregnant. This placed Kristen and her medical team in a quandary.

Dr. Robert Meguid and colleagues publish second edition of “The Johns Hopkins ABSITE Review Manual”

Book cover: The Johns Hopkins ABSITE Review ManualThe Johns Hopkins ABSITE Review Manual is a comprehensive general-surgery exam preparation book for surgical residents preparing for the annual American Board of Surgery In-Training Examination (ABSITE), as well as for practicing surgeons preparing for certification and re-certification. This project began while Dr. Meguid was a surgical resident at The Johns Hopkins Hospital. He and his colleagues recognized the need for a well-written and comprehensive set of practice questions.

The first edition, published in 2009, comprised a single full-length 225-question practice exam with detailed and illustrated explanations. It was written by 20 Johns Hopkins surgical residents and edited by the surgical faculty over the course of two years. It was well-received, and the authors were rapidly invited by the publisher, Lippincott Williams & Wilkins, to prepare a second edition.

This new edition includes a completely revised version of the first edition's exam plus an additional 225-question practice exam with detailed and illustrated explanations. The second edition took about four years to prepare, with a very satisfying end result. Dr. Meguid adds, “Most of the contributing authors and editors are from The Johns Hopkins Hospital, but we have begun to branch out to experts in their fields at other institutions, including the University of Colorado. We are looking forward to continuing this project in upcoming years.”

Patient goes a month without breathing, then trains for marathon

Victor Carlos, patient of Dr. Babu, during and after his medical crisis

One of our Division's newest surgeons, Dr. Ashok Babu, recently made national news on CNN for his work with Victor Carlos, a 42-year-old patient whose life was threatened by Acute Respiratory Distress Syndrome. Near the point of death, Carlos did not breathe for a full month but was kept alive via ECMO (extracorporeal membrane oxygenation). Almost miraculously, his lungs were able to heal during the weeks of inactivity and finally began functioning again. After not breathing for four weeks, Carlos made a full recovery and is now training for a marathon. Watch the video on the CNN website.
