Decompressive craniectomy surgery in a dog with intracranial extradural hematoma following blunt force trauma.

A young miniature poodle was presented following blunt force trauma to the head. The dog initially responded well to medical management before developing clinical signs associated with increased intracranial pressure 48 h post-injury that became refractory to hyperosmolar therapy. A computed tomography scan obtained 76 h post-injury showed a short, oblique, non-displaced, complete fissure in the right temporal bone and a second short, oblique, non-displaced, complete fissure in the ventral aspect of the temporal bone.

Surgical treatment of a persistent right aortic arch with concurrent patent ductus arteriosus in a 4-month-old German shepherd dog.

A 4-month-old intact female German shepherd dog was presented with a history of postprandial regurgitation, a palpably distended cervical oesophagus after eating, and poor weight gain despite a ravenous appetite. Computed tomography angiography, esophagoscopy and echocardiography identified a persistent right aortic arch with a concurrent patent ductus arteriosus (PDA) causing extraluminal oesophageal compression leading to marked segmental megaoesophagus. A heart murmur was not detectable.

Objective: To describe the perioperative findings and outcomes in dogs that underwent exploratory thoracotomy following porcupine quill migration and report (1) the use of traction alone for the removal of superficial quills in the pulmonary parenchyma, and (2) the use of exploratory pericardiotomy for the incidental identification of cardiac quills.

Animals: Five client-owned dogs.

Study Design: Short case series.

Surgical management and outcome of dogs with primary spontaneous pneumothorax: 110 cases (2009-2019).

Objective: To describe surgical management and associated outcomes for dogs with primary spontaneous pneumothorax.

Animals: 110 client-owned dogs with primary spontaneous pneumothorax that underwent surgical management.

Procedures: Medical records at 7 veterinary teaching hospitals were reviewed.

Presence of Qac genes in clinical isolates of methicillin-resistant and methicillin-susceptible Staphylococcus pseudintermedius and their impact on chlorhexidine digluconate susceptibility.

Objective: To evaluate the presence of quaternary ammonium compound (QAC) (resistance genes, qac A/B, smr, qacG, and qacJ, in clinical isolates of methicillin-susceptible Staphylococcus pseudintermedius (MSSP) and methicillin-resistant S pseudintermedius (MRSP) from dogs and the impact on in vitro chlorhexidine susceptibility.

Study Design: Experimental in vitro study.

Sample Population: Seventy isolates from dogs colonized or infected with MRSP (n = 50) or MSSP (n = 20).

Visuospatial skills are better predictors than dexterity for basic ultrasonographic and fluoroscopic skills in veterinary students.

Radiological skills including ultrasonography and fluoroscopy, require a combination of manual dexterity and visuospatial skill to develop competency. The ability to detect veterinary students with an interest in radiology but who are deficient in these skills, may permit more individual adaptations to training programs, allowing for students training in radiology to achieve maximal potential. The objective of this cohort study was to investigate whether innate dexterity and visuospatial skill could be used to predict performance of basic ultrasound and fluoroscopic skills in veterinary students.

Struvite urolithiasis with eosinophilic polypoid cystitis in a shih tzu dog.

A 7-year-old female spayed shih tzu dog was presented with hematuria of 4 weeks' duration. Radiographs revealed 1 cystic calculus. A polypoid mass was found incidentally during cystotomy and was removed by partial cystectomy.

Investigating the impact of innate dexterity skills and visuospatial aptitude on the performance of baseline laparoscopic skills in veterinary students.

Objective: To determine if manual dexterity and visuospatial skills can be used to predict baseline laparoscopic surgery skills in veterinary students.

Study Design: Pilot study.

Methods: Veterinary students (n = 45) from years 1-4 volunteered for this study.

Single incision laparoscopic-assisted ovariohysterectomy for an ovarian tumor in a dog.

This report describes a single-incision, laparoscopic-assisted ovariohysterectomy in a 6-year-old, intact female Keeshond dog for the staging and treatment of a left-sided ovarian tumor. Abdominal access was obtained using a modified-Hasson technique allowing for placement of a multi-channel, single incision laparoscopic surgery port. Following carbon dioxide insufflation, superficial laparoscopic exploration of the abdominal cavity was performed and then both ovarian pedicles were sealed and divided using a vessel-sealing device.

Investigating laparoscopic psychomotor skills in veterinarians and veterinary technicians.

Objectives: To determine the influence of age, year of graduation, and video game experience on baseline laparoscopic psychomotor skills.

Study Design: Cross-sectional.

Sample Population: Licensed veterinarians (n = 38) and registered veterinary technicians (VTs) (n = 49).

Evaluation of the Impact of Methicillin-Resistant Staphylococcus pseudintermedius Biofilm Formation on Antimicrobial Susceptibility.

Objective: To compare the minimum inhibitory concentration (MIC) of four antimicrobials in planktonic vs. biofilm-associated Staphylococcus pseudintermedius.

Study Design: In vitro study.

Impact of polymethylmethacrylate additives on methicillin-resistant Staphylococcus pseudintermedius biofilm formation in vitro.

Objective: To evaluate the impact of gentamicin, silver, or both additives in polymethylmethacrylate (PMMA) beads on methicillin-resistant Staphylococcus pseudintermedius (MRSP) biofilm formation in vitro.

Sample: 4 preparations of PMMA beads (formed with no additive [control], gentamicin, silver, and gentamicin and silver).

Procedures: Beads from each group were exposed to 10 MRSP isolates known to be strong biofilm formers.

Bacterial contamination of gloves worn by small animal surgeons in a veterinary teaching hospital.

This prospective study investigated bacterial contamination of surgical gloves during small animal surgical procedures and factors associated with glove contamination. The outer surface of surgical gloves was sampled and cultured after completion of surgical procedures. Bacterial presence and numbers were recorded.

Methicillin-resistant staphylococcal contamination of clothing worn by personnel in a veterinary teaching hospital.

Objective: To determine the methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant Staphylococcus pseudintermedius (MRSP) contamination rate of white coats (WC) and surgical scrubs (SS) worn by personnel at the Ontario Veterinary College Health Sciences Centre (OVCHSC) and to identify risk factors associated with clothing contamination.

Study Design: Cross-sectional study.

Sample Population: Personnel including clinical faculty, house officers, technicians, and veterinary students working at the OVCHSC.

Characterization of the biofilm forming ability of Staphylococcus pseudintermedius from dogs.

Background: Staphylococcus pseudintermedius is an opportunistic pathogen of dogs and has emerged as a leading cause of skin, wound and surgical site infections worldwide. Methicillin resistance is common and clinical infections as a result of methicillin-resistant S. pseudintermedius (MRSP) pose a clinical challenge.

In vitro miconazole susceptibility of meticillin-resistant Staphylococcus pseudintermedius and Staphylococcus aureus.

Background: The emergence and dissemination of meticillin-resistant staphylococci has created significant treatment challenges in veterinary medicine and increased interest in topical therapy for superficial infections. Concern has been expressed regarding the use of some topical antimicrobials in animals because of the potential for emergence of resistance, and additional options are required. Miconazole has limited antibacterial properties that include antistaphylococcal activity.
