{"title":"Clinical progression of a case of toe-tip necrosis syndrome in a feedlot steer.","authors":"Désirée Gellatly, Karen S Schwartzkopf-Genswein, Wiolene M Nordi, Tawni Silver, Murray Jelinski","doi":"","DOIUrl":"","url":null,"abstract":"A fractious feedlot steer was diagnosed with hind-limb lameness at 19 d on-feed. Clinical examination (Week 0) revealed white line separation of both lateral digits of both hind feet. Debridement confirmed toe-tip necrosis syndrome and the steer was treated with oxytetracycline (20 mg/kg, SC) and meloxicam (0.10 mg/kg, SC). Radiographs revealed osteolysis of P3 bones of both lateral digits, and by Week 4 the medial claw of the right hind foot was similarly affected. Clinical and radiographic examinations were conducted over a 25-week period. Rectal temperature, body weight (BW), cortisol (salivary and hair), haptoglobin, and complete blood (cell) counts were obtained over a 22-week period. New horn growth covered the debrided sole defects by Week 7, and radiographs confirmed remodelling of the P3 bones. At slaughter (Week 25), both hind feet appeared normal except for the lateral digits being longer than the medial digits. Radiographs indicated permanent changes in the P3 bones. Although this animal had osteolysis in 3 of 4 hind-limb digits, it was successfully treated with antimicrobial therapy and debridement on Week 0 followed by a second debridement in Week 2. Early intervention and debriding are central to preventing other sequelae such as deep digital sepsis. Key clinical message: A feedlot steer diagnosed with toe-tip necrosis syndrome, including osteolysis of 3 of 4 hind-limb digits, was successfully treated with debridement and antimicrobial therapy. Radiographic examinations confirmed remodeling of the distal phalanges (P3) and absence of active infection 25 wk after treatment. This case underscores that feedlot animals with osteolysis of multiple P3 bones can be treated successfully using debridement and antimicrobials.","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 5","pages":"514-522"},"PeriodicalIF":0.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12044963/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143966154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dog had undergone elective ovariohysterectomy, received nonsteroidal anti-inflammatory medication, and undergone an intestinal biopsy 1 d before presentation. On physical examination, the dog was in shock and had abdominal pain. There were an increased hematocrit, band neutrophilia with toxic change, and elevated urea concentration and liver enzyme values. Abdominal ultrasound revealed gas foci within the gastric wall, hepatic parenchyma, and colonic wall, consistent with emphysematous infection. Fecal analysis revealed low levels of Clostridium perfringens alpha toxin gene. The dog was treated medically with intravenous fluids, antimicrobial therapy, gastric decompression, and supportive treatments. Rapid clinical improvement was noted, accompanied by improvements on repeat abdominal ultrasonography examinations and blood work. A positive outcome was observed in this dog. The etiology for emphysematous infection was unclear, with multiple risk factors reported in human literature. In this case, administration of nonsteroidal anti-inflammatory medication, preexisting enteropathy, and recent abdominal surgery may have contributed to disease development. This is the first report of concurrent emphysematous gastritis, pneumatosis coli, and emphysematous hepatitis in a dog. This case report could aid practitioners in recognizing, diagnosing, and treating emphysematous infections in dogs with acute abdominal symptoms. Key clinical message: This is the first report of concurrent emphysematous gastritis, pneumatosis coli, and emphysematous hepatitis in a dog. The report provides information regarding the pathogenesis of, risk factors for, and diagnosis and treatment of emphysematous infections.","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 5","pages":"497-504"},"PeriodicalIF":0.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12044629/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143966413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eleven rams from 1 flock underwent 2 breeding soundness evaluations and necropsies. Brucella ovis was isolated from all semen ejaculates and confirmed via whole-genome sequencing. Despite above-threshold scrotal circumferences, all rams were categorized as unsatisfactory due to poor semen quality and leukocytes in semen. Semen motility values in 9 of 11 infected rams and morphologically normal sperm in all infected rams were below the recommended threshold values. Necropsies revealed gross lesions in 7 of 11 rams, with histopathology revealing inflammatory lesions in the epididymides, ductus deferens, ampullae, and seminal vesicles in all rams and in the testes in 9 of 11 rams. Inflammatory infiltrates were primarily lymphoplasmacytic and neutrophilic, with fibrosis, vasculitis, mineralization, and spermatic granulomas also observed. Key clinical message: Gross and histopathological lesions as well as semen characteristics were described in rams naturally infected with B. ovis. Most were subclinical cases. Veterinary practitioners can utilize changes in semen quality and the presence of leukocytes as potential indicators of B. ovis infection in rams, which may prompt further confirmatory testing.","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 5","pages":"523-532"},"PeriodicalIF":0.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12044969/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143977030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following physical and ultrasonic examination, pyometra secondary to vaginal obstruction caused by a persistent hymen was diagnosed. The hymen is composed of tissue remnants at the site of the junction of the caudal portion of the paramesonephric ducts (which form the vagina) and the urogenital sinus (which forms the vestibule). Failure of the normal canalization of the hymen may completely obstruct normal vaginal drainage of fluids produced by the female reproductive tract. Persistent hymen with retention of reproductive secretions in the vaginal vault has been described as a developmental defect in several domestic animal species. Hymenotomy and repeated luteolytic doses of prostaglandin F2α resulted in establishment of normal vaginal drainage and resolution of the pyometra. Diagnosis in an 18-year-old pygmy goat doe as described in this case report is unusual because the defect is most often diagnosed when a female is presented for attempted breeding following puberty. Key clinical message: We report a case of an 18-year-old pygmy goat doe diagnosed with pyometra secondary to vaginal obstruction caused by a persistent hymen. This case serves as an alert for clinicians to consider uncommon reproductive etiologies in older goats kept as pets.","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 5","pages":"533-536"},"PeriodicalIF":0.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12044627/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143960605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
