Spinal Fracture in a Foxsnake: Case Report
A foxsnake was presented to the ISU Small Animal Clinic with a spinal fracture. The fracture was immobilized using a tubular splint. Healing was complete at 12 weeks, and except for slight neurological deficits the snake recovered completely
Identification by whole genome sequencing of genes associated with delayed postoperative hemorrhage in Scottish deerhounds
Abstract Background Delayed postoperative hemorrhage (DEPOH) is an important health concern for Scottish deerhounds. Hypothesis/Objectives Identify genes associated with DEPOH in Scottish deerhounds. Animals Two hundred sixty‐nine privately owned Scottish deerhounds. Methods Retrospective case‐control study. DEPOH cases and controls were identified through an owner health survey. Genome‐wide association analysis was performed using whole genome sequences from 8 cases and 17 controls. All cases and controls were genotyped for selected variants. Results Of 269 dogs, 10 met inclusion and exclusion criteria for DEPOH, while 62 controls had undergone similar surgical procedures without DEPOH. Genome‐wide association analysis identified a single locus on chromosome 9 spanning 40 genes. One of these genes (SERPINF2 encoding alpha‐2 antiplasmin) was directly linked to the pathophysiology of DEPOH. The entire cohort was genotyped for a missense SERPINF2 variant (c.605 C>T; p.A202V). Compared to dogs with the reference C/C genotype, the likelihood of DEPOH was significantly higher for dogs with the T/T genotype (odds ratio [OR] = 1235; 95% confidence interval [CI] = 23‐6752; P = 0.0005) and with the C/T genotype (OR = 28; 95% CI = 1.4‐542; P = 0.03). Conclusions and Clinical Importance SERPINF2 is associated with DEPOH in Scottish deerhounds. Genetic testing might be able to identify dogs that are susceptible to DEPOH

Topical Fluorouracil: II. Postoperative Administration in an Animal Model of Glaucoma Filtering Surgery
• Unilateral posterior lip sclerectomies were performed in ten owl monkeys. Five milligrams of fluorouracil was injected subconjunctivally in each operated eye immediately after surgery. Three drops (approximately 2.4 mg/drop) of fluorouracil were instilled ten minutes apart in each operated eye twice daily on postoperative days 1 through 7 and once daily on postoperative days 8 through 15, 17, 19, and 21. One monkey died on the seventh postoperative day; its death could not be attributed to systemic fluorouracil toxicity. All of the operated eyes had filtering blebs after the full course of fluorouracil, but seven also had corneal epithelial defects. By the seventh postoperative week, two of the operated eyes manifested moderately severe corneal opacification. Ten weeks postoperatively, the electroretinographic a- and b-wave amplitudes averaged 17% and 12% less, respectively, in the seven operated eyes without clinically significant corneal opacification than in the unoperated fellow eyes. Only two eyes had blebs after the 12th postoperative week. Histopathologic examination was performed on five eyes, of which only two revealed patent sclerostomies. Although topical fluorouracil appears to delay bleb scarring, the corneal findings suggest that it may be more toxic than subconjunctival fluorouracil
