Abstract

OBJECTIVE:To compare clinical outcomes of dogs with congenital intrahepatic portosystemic shunts (CIHPSS) treated with cellophane banding (CB) or percutaneous transvenous coil embolization (PTCE).

STUDY DESIGN:Dual-institutional retrospective study.

ANIMALS:Fifty-eight dogs with CIHPSS (2001-2016).

METHODS:Medical records of dogs undergoing CB or PTCE for CIHPSS were reviewed for signalment, body weight, hematologic values, shunt location, attenuation technique, procedure time, duration of hospitalization, complications, date of follow-up, and cause of death if applicable.

RESULTS:Thirty-one dogs underwent CB, and 27 dogs underwent PTCE. No differences were detected between groups for gender, preoperative packed cell volume, albumin, cholesterol, or bile acids. Body weight was greater in dogs treated via PTCE. Shunts differed in location because dogs undergoing CB were diagnosed with more left divisional shunts compared with PTCE dogs. Procedural duration of CB and PTCE did not differ. Dogs treated with CB sustained more minor postoperative complications and were hospitalized longer than dogs treated with PTCE. The 1-year and 2-year survival rates were 89% for the CB group and 87% and 80% for the PTCE group, respectively. The proportion surviving at 5 years was 75% and 80% for CB dogs and PTCE dogs, respectively.

CONCLUSION:CB and PTCE are associated with similar short-term and intermediate-term survival. PTCE is a minimally invasive alternative to CB via celiotomy. However, CB allows concurrent abdominal procedures requiring the same approach.

Head and dental injuries among farriers and hoof care practitioners: A nationwide survey in Switzerland.
Head/face injuries were more frequently reported by farriers than hoof care practitioners (60.6% and 20.7%, respectively). The rate of dental injuries, mainly related to a horse kick, was 11.1% and 1.9% among farriers and hoof care practitioners, respectively. Negligence in wearing mandatory eye protection was reported by 37.5% of respondents.

Simple, Practical, and Inexpensive Diagnostics: They Tell Us More Than We May Think
Despite the ever-expanding assortment of diagnostic tests becoming available, do not overlook simple, practical, and affordable diagnostic tests. When performed correctly, these economical tests provide a wealth of information to facilitate diagnosis and treatment of patients.

Understanding the Role of Therapy Dogs in Human Health Promotion.
Therapy dog programmes are delivered across a variety of settings including hospitals, aged care facilities and mental health services, highlighting the important role they play in human health outcomes. Research has shown that that there are biomarkers for stress in humans and other animals engaged in human-animal interactions. This review aims to assess the impact of human-animal interactions on therapy dogs engaged in providing support to human health.

High-pressure injection of paint into the hand: A small injury with serious consequences.
High-pressure injection injury to the hand is a serious lesion threatening the limb. Several injected materials are involved, and paint is known to have the most serious consequences, with a high amputation rate. Early diagnosis and prompt treatment are two important prognostic factors for a better outcome.

Immunosuppressant Therapy in Small Animal Medicine: What, When, and Why
Immunosuppressant drugs are categorized into steroid medications (e.g., prednisone, prednisolone, dexamethasone, budesonide), calcineurin inhibitors (e.g., cyclosporine), antiproliferative medications (e.g., azathioprine, mycophenolate, leflunomide), and mechanistic target of rapamycin inhibitors (not currently used routinely in veterinary medicine). This article focuses on the first 3 categories.
