Intervertebral disk disease is common in humans and dogs but is rarely reported in horses. In this case report, we describe an 11-year-old American Saddlebred gelding with a 2-month history of pain and progressive neurological abnormalities (ataxia, conscious proprioceptive deficits involving all four limbs, toe dragging, and restricted neck flexion) while being worked as a Saddleseat show horse. Radiographs of the cervical spine showed a loss of the intervertebral disk space at C6–C7. At necropsy, nearly complete loss of the intervertebral disk at C6–C7 was seen, with marked eburnation and subchondral sclerosis of the adjacent vertebral endplates that were confirmed by histopathology. Many of the marrow spaces of the affected vertebral bodies were filled with cartilage and others contained variable amounts of fibrous connective tissue (myelofibrosis). To our knowledge, these pathological lesions are rarely reported in the literature and appear to represent a chronic, end-stage phase of cervical vertebral stenosis. 相似文献

Objective – To determine: (1) changes in blood ammonia, bile acid (BA), bilirubin, triglyceride, and glucose concentrations and liver enzyme activities in perioperative colic patients and (2) the association between these laboratory findings and short‐term survival. Design – Prospective observational clinical study. Animals – Thirty‐two adult horses undergoing exploratory celiotomy for colic. Interventions – None. Measurements and Main Results – Blood samples were collected preoperatively and at 24–36 and 72–84 hours postoperatively and analyzed for blood ammonia, BA, bilirubin, triglyceride, and glucose concentrations and sorbitol dehydrogenase (SDH) and gamma glutamyl transferase (GGT) activities. Short‐term survival was defined as survival to hospital discharge. Data were analyzed using a Fisher's exact test and analysis of variance. Mildly increased blood ammonia concentrations were present in 2 horses at admission. Postoperative blood ammonia concentrations were within reference intervals in all horses. There were increases in liver enzyme activities as well as in BA, triglyceride, and total bilirubin concentrations. Horses with markedly increased admission BA concentrations and SDH activities did not survive. BA concentrations and SDH activities decreased postoperatively. There was no association between GGT activity and survival; GGT activity remained increased postoperatively. Blood triglyceride concentration was increased in almost all horses postoperatively; horses that did not survive had higher triglyceride concentrations at 24–36 hours postoperatively than horses that survived. Conclusion – Alterations in metabolism and hepatobiliary function are common in colic patients. The results of this study provide further prognostic indices for colic patients and highlight areas for improvement in patient management. 相似文献
