Objectives: To investigate the development of surgical skills of veterinary undergraduates and determine the number of canine ovariohysterectomies required to achieve competency and reduce levels of student concern. This was compared to student expectations and that of employers regarding surgical ability and provision of support to new graduates. Methods: A questionnaire regarding surgical concerns was sent to final year veterinary students enrolled within the University of Bristol, UK. A questionnaire was also sent to 200 UK veterinary practices regarding their impressions of surgical competence of new graduates and their provision of supervision. The responses were compared. Eleven additional final year students performed five canine ovariohysterectomies and graded their concerns. The number of supervised canine ovariohysterectomies required until competency was determined. Results: 80·4% of final year veterinary undergraduates replied that the surgical procedure which they were most concerned about their ability to perform was canine ovariohysterectomy. Students and veterinary practitioners differed in their opinions regarding whether they considered canine ovariohysterectomy to be a “day one skill” and what were desirable levels of supervision. Completing a minimum of four canine ovariohysterectomies led to 81·8% of students being assessed as competent. Clinical Significance: An unrealistically high expectation of competency by students may be a source of stress and concern. Employers should aim to provide hands‐on support whilst new graduates complete at least four canine ovariohysterectomies. Postoperative haemorrhage is uncommon but is the main concern for students.

A standard angle cannot be recommended for screw placement in lag fashion within the canine sacrum in the dorsal plane. Because of the narrow width of the safe corridor, preoperative measurements on radiographs are recommended and a range of angled drill guides may be useful to decrease surgeon margin of error.

Vitamin D insufficiency is regularly observed in human patients with tuberculosis but it is unknown if spontaneous mycobacteria infections in other species are associated with suboptimal vitamin D status. Serum 25 hydroxyvitamin D (25(OH)D) concentrations were significantly lower in cats with mycobacteriosis than in healthy cats (P < 0.001).

This article describes the MRI features of a middle ear cholesteatoma in an 8 yr old flat-coated retriever. Physical examination revealed pain on opening the jaw, and otoscopic examination showed tympanic membrane rupture associated with hyperplastic tissue at the entrance of the middle ear. Standard MRI sequences allowed for the identification of a severely expanded bulla containing material that was isointense to brain tissue on T1-weighted images and of mixed intensity on T2-weighted and fluid-attenuated inversion recovery sequences. No postcontrast enhancement of the content was present, but the lining of the bulla was partially enhanced. The images allowed evaluation of the surgical margins and the secondary changes due to the expansion of the mass. Surgery was performed and histopathology confirmed the presumptive diagnosis of cholesteatoma. In the present case, MRI appeared to serve as a good alternative to computed tomography for the diagnosis of cholesteatoma.
