Cate Dolan’s excellent adventure

December 13th, 2010

Cate Dolan, class of 2012, spent eight weeks last summer at the National Zoological Gardens in Pretoria, South Africa, evaluating the histopathology of a group of wild-captured reptiles from Magagascar. The project was part of the Biomedical Sciences Research Program, and was also sponsored by an International Veterinary Students Association (IVSA) travel scholarship. She wanted to travel outside of the United States in the summer, both to explore veterinary medicine abroad, and just to have an adventure and see a new part of the world.

She found the project through Dr. Löhr, who advised her as part of the Biomed Research Program. Dr. Löhr oversees the summer research programs, and had a few different potential opportunities for international projects. This one in particular appealed to Cate because it was in a culture that was different than anywhere she had previously traveled.

In South Africa, she was supervised by Dr. Emily Lane, the pathologist at the veterinary research center at the zoo in Pretoria. Dr. Löhr had met Dr. Lane while traveling in South Africa. “One of the ladies I worked with this summer put it nicely, ‘you are here to learn and to enjoy’ — I learned and enjoyed in many ways this summer, both while working on my research project and while out exploring South Africa.”

During her time in Pretoria, she made cross-sectional microscope slides of the chameleons, geckos, and iguanas she was analyzing, and then recorded all of the normal and abnormal histologic findings that were present on the slides. She is currently collating her data and evaluating the implications of her findings. While she was there, she also got to take part in daily activities of the veterinary pathology lab at the zoo, including post mortem examinations of a number of exotic animals (a cheetah, an antelope, a ground hornbill— an endangered bird, a boomslang — a very poisonous snake, a porcupine, etc.).

When she wasn’t working on her project, she kept quite busy playing underwater hockey with the local team and rock climbing with friends in the Mountain Club. On weekends she took trips, often to go climbing, to various parts of South Africa, including Cape Town, the Drakensburg Mountains, the Magaliesburg Mountains, Waterval Boven and Kruger National Park. Cate says, “Overall, it was a wonderful experience, and I gained a lot of knowledge both about histopathology and about the South African culture.”

One health, one world, in action

December 13th, 2010

Sonja LapinskiFourth-year student Sonja Lapinski brought the veterinary perspective to the School of Medicine at Oregon Health Sciences University with her presentation entitled “One health, one world, in action: The evolution of a student-led veterinary service trip to Nicaragua.” The presentation was given as part of Conversations in Global Medicine, an elective course for medical students. At her presentation on December 8th, there were about 45 people in attendance, including faculty and staff.

Sonja began by describing the goals of the International Veterinary Student Association, both in terms of the positive impact on the animal and human populations of underdeveloped areas, and in terms of the benefits derived by veterinary students who participate in the planning and implementation of a service trip. She presented statistics showing how the numbers of those participating and the numbers and types of animals seen have increased over the last five years. She described the clinic and field service set-up and presented some typical cases.

The enthusiastic audience had questions that ranged from medical, to public health-related, to “how many years is vet school and what is your curriculum like?” In discussions following the presentation, faculty and students expressed interest in collaborating on investigations of zoonotic diseases and other issues of public health.

Welcome new house officers and staff

Staff

Jessica (Jo) Okhuysen, certified veterinary techician

Jo takes care of large animals during the graveyard shift and “dabbles in medicine, surgery and emergency — that’s the excitement of overnights as anything can happen.” She really enjoys interacting and learning from the animals, including the clinicians and students. She has three dogs and three cats. As a workaholic, she works at an emergency clinic for small animals on her days off. She’s also an outdoor enthusiast who enjoys nature, running in the rain with her dogs, playing soccer (go Scraps!).

Originally from Madrid, Spain, Dr. del Alamo performs anesthesia and supervises students in anesthesia for small and large animals (occasionally on exotic and wild species). Dr. del Alamo wrote, “Coming from Spain, I had never heard a word about Oregon and had never been on the west coast. When I came here I found out how amazing Corvallis is and I’m so glad I applied for this residency and got it!” Her dog, Sasha, stayed with her parents in Spain.

A young horse facing a fatal disease is treated successfully with state-of-the-art techniques

November 30th, 2010

A two-year-old Arabian gelding was referred to OSU Lois Bates Acheson Veterinary Teaching Hospital for possible guttural pouch infection. He presented for blood coming from his right nostril. The diagnosis of guttural pouch mycosis was confirmed with an upper airway endoscopic evaluation. (See Figure 1).

Figure 1. Endoscopic picture of right guttural pouch mycosis

Guttural pouch mycosis is a serious and potentially fatal fungal infection. It is unknown why or how the fungal infection begins. The guttural pouch is an outpouching of the ear canals whose function is not completely understood. The infection causes inflammation and damage to blood vessels and nerves in the guttural pouch leading to the clinical signs. These include a bloody nasal discharge, swallowing difficulties, unusual head posture, head shaking and head shyness. If left untreated the fungus can erode into the carotid artery leading to a fatal hemorrhage.

The gelding returned to OSU Veterinary Teaching Hospital for treatment. Multiple methods of treatment have been used to treat guttural pouch mycosis from antifungal therapy to surgical procedures intended on depriving blood supply from the fungal organism. Computed tomography (CT scan) was done with intravenous contrast media in order to highlight and define the affected blood vessels. A two-centimeter aneurysm was identified in the right internal carotid artery. The following day he was placed under general anesthesia a second time for the placement of the vascular occlusion plugs in the internal carotid artery. Dr. Michael Huber exteriorized the common carotid artery so the aneurysm could be occluded using nitinol vascular occlusion plugs. These were placed by cardiologist Dr. David Sisson on either side of the aneurysm using fluoroscopy thus stopping blood flow past the aneurysm.

He went home three days following the procedure and is doing well at home. He will return to the hospital for a recheck in two months.

Finally, a special thanks to all the clinicians and technicians that contributed to his treatment for without the enormous effort by the cardiology service, radiology department, large animal surgery service, anesthesia department, and large animal internal medicine service it would not have been successful.

Special thanks to John Schlipf, Jr., DVM, DACVIM-Large Animal Internal Medicine; David Sisson, DVM, DACVIM-Cardiology; Tom Riebold, DVM, DACVA-Anesthesia; Mike Huber, DVM, MS, DACVS-Large Animal Surgery; Susanne Stieger-Vanegas, Mag. vet. med., Dr. med. vet., DECVDI-Radiology, PhD; Jason Weist, Computed Tomography Technician.

Students in Vet Med and Pharmacy collaborate on presentation

November 30th, 2010

Meg Black and Sonja Lapinski

A couple months ago, Meg Black, a 2011 PharmD candidate sent out a plea for a veterinary student who would be willing to collaborate on a presentation at the College of Pharmacy on pet prescription and over-the-counter drugs. Sonja Lapinski, class of 2011,  emailed her a couple weeks later to see if anyone had taken the bait. No one had, so Sonja ended up volunteering to help her out.

“We held a talk, which was open to both colleges, on October 28 in the pharmacy building,” commented Sonja. ” It was well attended, and people asked great questions. A handful of vet students even made it over, in spite of a competing talk about internships and residencies. Dr. Terry Crowder, the veterinary teaching hospital’s veterinary pharmacist, was in attendance as well. He helped answer questions and provided much needed moral support. Both Meg and I look forward to hearing about further collaborations between our professional programs—we believe there is so much we can learn from each other!”
