Feline chronic gingivostomatitis (FCGS) is a disease characterized by protracted and potentially debilitating oral inflammation in cats, the etiology of which is currently unknown. The purpose of this review is to apply an evidence-based medicine approach to systematically review and critically evaluate the scientific literature reporting the outcome of medical and surgical management of FCGS. Those articles meeting inclusion criteria were reviewed and assigned an “Experimental Design Grade” (EDG) and an “Evidence Grade” (EG) in order to score relative strength of study design and produced data. Studies were evaluated and compared, especially highlighting the treatments, the outcomes, and the therapeutic success rates. This review found a lack of consistency between articles’ data, rendering direct comparison of results unreliable. The field of FCGS research, and ultimately patient care, would benefit from standardizing studies by adopting use of a consistent semi-quantitative scoring system and extending follow-up duration. Future researchers should commit to large prospective studies that compare existing treatments and demonstrate the promise of new treatments.

Objective: To describe the application of 3-dimensional (3D) printing in advanced oral and maxillofacial surgery (OMFS) and to discuss the benefits of this modality in surgical planning, student and resident training, and client education.Study design: Retrospective case series.Animals: Client-owned dogs (n 5 28) and cats (n 5 4) with 3D printing models of the skulls. Methods:The medical records of 32 cases with 3D printing prior to major OMFS were reviewed.Results: Indications for 3D printing included preoperative planning for mandibular reconstruction after mandibulectomy (n 5 12 dogs) or defect nonunion fracture (n 5 6 dogs, 2 cats), mapping of ostectomy location for temporomandibular joint ankylosis or pseudoankylosis (n 5 4 dogs), assessment of palatal defects (n 5 2 dogs, 1 cat), improved understanding of complex anatomy in cases of neoplasia located in challenging locations (n 5 2 dogs, 1 cat), and in cases of altered anatomy secondary to trauma (n 5 2 dogs). Conclusion:In the authors' experience, 3D printed models serve as excellent tools for OMFS planning and resident training. Furthermore, 3D printed models are a valuable resource to improve clients' understanding of the pet's disorder and the recommended treatment.Clinical relevance: Three-dimensional printed models should be considered viable tools for surgical planning, resident training, and client education in candidates for complex OMFS.

The objective of this study is to describe the clinical features and computed tomography (CT) findings of dogs with retrobulbar disease. There are two facets to this study: a retrospective case series in which findings of dogs with primary vs. secondary retrobulbar disease are described, and a retrospective cross-sectional study in which computed tomography findings of dogs with retrobulbar neoplasia vs. infection/inflammation are described and compared. The medical records of 66 client-owned dogs diagnosed with retrobulbar disease between 2006 and 2016 were reviewed. Clinical information including signalment, the specialty service to which the dog was presented, clinical signs, physical examination findings, diagnostic results, treatment, and outcome were documented. Diagnostic imaging and histopathology were reviewed. Forty-one dogs (62.1%) were diagnosed with primary disease of the retrobulbar space; 25 dogs (37.9%) were considered to have secondary retrobulbar disease. Of the 41 dogs with primary retrobulbar disease, 19 were diagnosed with neoplasia, 19 with infectious/inflammatory disease, and 3 suffered traumatic insult to the retrobulbar space. Of the 25 dogs with secondary retrobulbar disease, 21 were diagnosed with neoplasia, 3 with infectious/inflammatory disease, and 1 with a cyst. Dogs had a combination of ocular, oral, and/or nasal clinical signs. CT findings of orbital osteolysis, orbital periosteal reaction, and presence of a retrobulbar mass were significantly associated with neoplasia, while zygomatic salivary gland enlargement, retrobulbar mass effect, and mandibular lymphadenopathy were more often associated with infectious/inflammatory disease. CT findings overlap among different retrobulbar diseases, but new bone formation and lysis are more often associated with neoplasia. Disease originating from the retrobulbar space was equally likely to be infectious/inflammatory (n = 19) or neoplastic (n = 19), based on definitive diagnostic results of dogs with primary retrobulbar disease. Due to the clinical ramifications of these disorders, the diagnosis and treatment of these cases should be managed with a multi-specialty approach.

Physicians and veterinarians are increasingly expected to collaborate across disciplines; however, in most cases their education and training remain isolated within their respective professions. Medical and veterinary students are rarely provided with opportunities for inter-professional learning during their coursework and clinical training. One Health serves as an ideal framework for developing problem-focused curricula that promote inter-professional teamwork. One Health issues (e.g., zoonotic diseases, water pollution, toxic waste, impact of climate change, and food safety and security) not only engage students across disciplines, but require faculty and senior leadership across various health-related fields to share knowledge and balance perspectives throughout curriculum development and implementation. In this article, we report on one of several interactive, small-group, case-based One Health curricular exercises developed collaboratively by students and faculty in our Schools of Medicine and Veterinary Medicine to ensure that all students, regardless of background or intended specialty, would receive a basic introduction to inter-professional collaboration in the context of a One Health clinical problem of the sort they might encounter in their future practice. Toxoplasmosis ( Toxoplasma gondii infection) was selected as the first case because of the potentially different perspectives that medical and veterinary practitioners may have on advising a pregnant woman with regard to risk factors, prevention, testing, and treatment. Our goal was to develop an evidence-based approach to this clinical case that could be used by both professions to assess environmental and zoonotic risk factors for T. gondii in human pregnancies.

This study evaluates whether medical and veterinary students' attitudes toward "One Health" and interprofessional education changed after participating in a joint small group learning exercise focused on risk factors associated with zoonotic disease. A survey was distributed to third-year medical students (n = 98) and second-year veterinary students (n = 140), each with a 95% response rate. Overall, 92% of veterinary students and 73% of medical students agreed or strongly agreed that "One Health" was relevant to their desired specialty. Students from both schools largely agreed that interprofessional education should be a goal of the curriculum for their school, and that interprofessional approaches strengthen their overall education. Students reported increased confidence in their communication skills and improved ability to contribute to One Health collaborative teams. This educational intervention, built around a patient case, focused on a variety of learning objectives including skills (such as communication), knowledge (of zoonotic toxoplasmosis) and attitudes (toward collaborative learning and practice). By sparking an interest in One Health during their early professional education, we sought to encourage a new generation of physicians and veterinarians to adopt a more collaborative spirit to their clinical practice, which will ultimately benefit human, animal and environmental health.

SummaryMaxillae and/or mandibles from 76 walruses (Odobenus rosmarus) were examined macroscopically according to predefined criteria. The museum specimens were acquired between 1932 and 2014. Forty-five specimens (59.2%) were from male animals, 29 (38.2%) from female animals and two (2.6%) from animals of unknown sex, with 58 adults (76.3%) and 18 young adults (23.7%) included in this study. The number of teeth available for examination was 830 (33.6%); 18.5% of teeth were absent artefactually, 3.3% were deemed to be absent due to acquired tooth loss and 44.5% were absent congenitally. The theoretical complete dental formula was confirmed to be I 3/3, C 1/1, P 4/3, M 2/2, while the most probable dental formula is I 1/0, C 1/1, P 3/3, M 0/0; none of the specimens in this study possessed a full complement of theoretically possible teeth. The majority of teeth were normal in morphology; only five teeth (0.6% of available teeth) were malformed. Only one tooth had an aberrant number of roots and only one supernumerary tooth was encountered. No persistent deciduous teeth were found in any of the young adult or adult specimens, nor were any specimens affected by enamel hypoplasia. The majority of teeth (85.5%) displayed attrition/abrasion. Of the adult and young adult specimens, 90.8% showed some degree of attrition/abrasion on at least one tooth. Tooth fractures were noted in eight walruses, affecting 10.5% of specimens and 1.3% of the total number of teeth, nearly three-quarters of which were maxillary canine teeth (tusks). Three specimens (3.9%), all adult males, displayed overt periapical disease. The majority (99.2%) of dental alveoli did not have bony changes indicative of periodontitis, with only five specimens (6.6%) affected by periodontitis. Lesions consistent with temporomandibular joint osteoarthritis (TMJ-OA) were found in 46 specimens (60.5%) and TMJ-OA was significantly more common in adults than young adults and males than females. Although the clinical significance of dental and TMJ pathology in the walrus remains unknown, the occurrence and severity of these lesions may play an important role in the morbidity and mortality of this species.
