Objective: The objective of this Case Report was to describe the clinical manifestation and postmortem findings of a horse evaluated for recurrent colic diagnosed with pyloric aplasia and an ectopic duodenal papilla.

Animal: 13-year-old Quarter Horse gelding.

Clinical presentation, progression, and procedures: The horse was presented to a referral center for signs of colic that were unresponsive to management on the farm. No abnormalities were noted on rectal palpation; however, upon passage of a nasogastric tube, 31 L of net gastric reflux was obtained. Gastroscopy noted grade IV squamous ulceration and moderate glandular ulceration, severe gastric dilatation, an abnormally positioned gastric outflow tract, and an ectopic duodenal papilla leaking bile-like fluid directly into the stomach.

Treatment and outcome: The horse was initially treated with gastroprotectants, promotility agents, and dietary modifications. Following treatment failure and repeated episodes of colic with increasing severity, the horse was euthanized and a necropsy performed. At necropsy, it was confirmed that the aboral aspect of the stomach formed a dilated pouch and continued directly into the proximal duodenum with no discernible pyloric sphincter. The area of the pylorus was delineated by a faint indentation. The ectopic duodenal papilla was traced to the liver.

Clinical relevance: Congenital gastric abnormalities, even in adult horses, should be considered as differential diagnoses when investigating horses presenting with a history of chronic colic. Neither pyloric aplasia nor an ectopic duodenal papilla have been described in the equine literature, and this Case Report raises awareness of the presence of such malformations and their manifestations.

目的:本病例报告的目的是描述一匹马的临床表现和尸检结果,这匹马因反复绞痛被诊断为幽门增生和十二指肠乳头异位:这匹马因肠绞痛症状而被送往转诊中心,但对农场的治疗无效。直肠触诊未发现异常,但在插入鼻胃管后,发现胃净反流 31 升。胃镜检查发现了 IV 级鳞状溃疡和中度腺状溃疡、严重胃扩张、胃流出道位置异常以及十二指肠乳头异位,胆汁样液体直接渗入胃中:这匹马最初接受了胃保护剂、促进剂和饮食调整治疗。治疗失败后,马匹反复腹绞痛,且越来越严重,于是马匹被安乐死,并进行了尸体解剖。尸体解剖证实,胃的口部形成一个扩张的小囊,并直接延伸到十二指肠近端,没有明显的幽门括约肌。幽门部位有一个微弱的凹痕。异位十二指肠乳头一直延伸到肝脏:临床意义:在对有慢性腹绞痛病史的马匹进行调查时,即使是成年马的先天性胃畸形也应作为鉴别诊断考虑。本病例报告提高了人们对此类畸形及其表现的认识。

Tranexamic acid stops hyperfibrinolysis in dogs with hemorrhagic shock: a randomized, controlled clinical trial. 氨甲环酸能阻止失血性休克犬体内的高纤维蛋白溶解:一项随机对照临床试验。
IF 1.6 2区 农林科学 Q2 VETERINARY SCIENCES Pub Date : 2024-09-20 Print Date: 2025-01-01 DOI: 10.2460/javma.24.03.0216

Objective: To determine the effect of tranexamic acid (TXA) on clot hyperfibrinolysis (HF), defined as excessive clot lysis at 30 minutes (LY30%), with rapid thromboelastography (rTEG) or rTEG samples spiked with tissue plasminogen activator (tPA-stressed rTEG), in dogs with hemorrhagic shock.

Methods: Prospective blinded clinical trial at 2 teaching hospitals, March 16, 2018, to May 20, 2022. Twenty-five dogs with hemorrhagic shock and HF were treated with standard care plus either TXA (20 mg/kg; TXA group) or saline (SAL group) over 20 minutes followed by an infusion of the same dose over 8 hours. Rapid TEG and tPA-stressed rTEG assays were performed immediately before study drug administration and at 8, 12, and 24 hours afterwards (T0, T8, T12, and T24, respectively).

Results: 4 dogs died or were euthanized before the end of the study period due to disease/injury severity. All survivors had normal rTEG LY30% values after T0; the value for 1 nonsurvivor increased at T8. The tPA-stressed LY30% normalized in all TXA (n = 14) and 8 of 11 SAL dogs at T8; TXA dogs had lower median tPA-stressed rTEG LY30% values at T8 and T12 than SAL dogs (P = .001 and .02, respectively). There was no treatment effect on blood product administration or survival, and no adverse effects were attributed to TXA administration.

Conclusions: Resuscitation with or without TXA reduced HF identified by tPA-stressed rTEG. Hyperfibrinolysis was completely suppressed at the conclusion of the 8-hour TXA infusion.

Clinical relevance: Although TXA treatment stopped HF, there was no effect on survival or transfusion requirements.

目的确定氨甲环酸(TXA)对失血性休克犬血栓纤溶亢进(HF)的影响,HF定义为30分钟时血栓过度溶解(LY30%),使用快速血栓弹力图(rTEG)或添加组织纤溶酶原激活剂的rTEG样本(tPA-stressed rTEG):2018年3月16日至2022年5月20日,在2家教学医院进行前瞻性盲法临床试验。25只患有失血性休克和高血压的狗接受了标准护理加20分钟TXA(20毫克/千克;TXA组)或生理盐水(SAL组)治疗,然后在8小时内输注相同剂量。在给药前和给药后 8、12 和 24 小时(分别为 T0、T8、T12 和 T24)进行快速 TEG 和 tPA 压力 rTEG 检测:结果:4 只狗在研究结束前因疾病/损伤严重而死亡或安乐死。所有幸存者在 T0 后的 rTEG LY30% 值均正常;1 只非幸存者的值在 T8 时升高。T8时,所有TXA犬(n = 14)和11只SAL犬中的8只的tPA压力LY30%值恢复正常;T8和T12时,TXA犬的tPA压力rTEG LY30%中位值低于SAL犬(P = 0.001和0.02)。治疗对血液制品用量或存活率没有影响,TXA 给药也没有导致不良反应:结论:使用或不使用TXA进行复苏都能降低通过tPA应激rTEG确定的高频率。结论:无论使用或不使用TXA复苏,都能减轻tPA-Stressed rTEG确定的HF,8小时TXA输注结束时,高纤维蛋白溶解完全被抑制:临床相关性:虽然TXA治疗阻止了心房颤动,但对存活率或输血需求没有影响。

Objective: To describe clinical and radiographic outcomes in dogs with uncomplicated pneumonia receiving a shorter (2-week) versus longer (4-week) duration of antimicrobial therapy.

Animals: 30 client-owned dogs with radiographic evidence of pneumonia.

Methods: Dogs were randomly assigned to either a 2-week course of antimicrobials followed by a 2-week course of placebo medication (2-week group) or a 4-week course of antimicrobials (4-week group). All study investigators and owners were masked to the treatment group. Dogs were reevaluated at 12 ± 2 days and again at 28 ± 2 days for a physical examination and thoracic radiography. Standard documentation at visits included owner-reported clinical signs, nurse-acquired history, the clinician's physical examination, the number of affected lung lobe segments, and the global radiographic severity scores assigned. Outcomes investigated included the persistence of clinical and radiographic signs of pneumonia.

Results: 28 dogs (93.3%) experienced complete resolution of clinical signs by the first visit, and no dogs in either group experienced relapse of clinical signs during the study period. Eighteen of 30 dogs (60%) and 25 of 30 dogs (83%) experienced complete resolution of radiographic lesions at the first and second study visits, respectively. The remaining 5 dogs (17%) had either stable (4 dogs) or continued (1 dog) improvement in radiographic lesions.

Clinical relevance: Resolution of clinical and radiographic signs followed similar courses in dogs with uncomplicated pneumonia receiving a 2-week course of antimicrobials compared to a 4-week course. Clinical signs may be more useful for guiding discontinuation of antimicrobial therapy for pneumonia than radiographic signs.

目的:描述接受较短(2 周)和较长(4 周)抗菌治疗的无并发症肺炎犬的临床和影像学结果:描述接受较短(2 周)和较长(4 周)抗菌药治疗的无并发症肺炎患犬的临床和影像学结果:方法:将狗随机分配到先服用 2 周抗菌药再服用 2 周安慰剂药物的疗程组(2 周组)或服用 4 周抗菌药的疗程组(4 周组)。所有研究人员和狗主人都被蒙在治疗组之外。在 12 ± 2 天和 28 ± 2 天时分别对狗狗进行复查,以进行体格检查和胸部 X 射线检查。就诊时的标准记录包括犬主报告的临床症状、护士获得的病史、临床医生的体格检查、受影响肺叶节段的数量以及总体放射学严重程度评分。结果:28 只狗(93.3%)的临床症状在第一次就诊时已完全消失,在研究期间,两组中都没有狗的临床症状复发。30 只狗中有 18 只(60%)和 25 只(83%)分别在第一次和第二次就诊时完全消除了影像学病变。其余 5 只狗(17%)的影像学病变要么稳定(4 只狗),要么继续改善(1 只狗):临床临床相关性:与 4 周抗菌药疗程相比,接受 2 周抗菌药疗程的无并发症肺炎患犬的临床症状和影像学症状的缓解过程相似。在指导停止肺炎抗菌治疗时,临床症状可能比影像学症状更有用。

Objective: To describe CT findings and epidemiologic features of nasal and paranasal disease of rabbits (Oryctolagus cuniculus).

Methods: An electronic search was performed for rabbits that underwent skull CT from 2004 to 2024 and had findings consistent with nasal/paranasal or maxillary dental disease. History, signalment, and physical examination findings were recorded and reevaluated retrospectively for evidence of changes to the nasal passages, paranasal sinuses, and nearby associated anatomy. Data were analyzed with descriptive statistics, ordinal mixed logistic regression, and correlation analysis.

Results: 100 studies from 69 rabbits were reviewed. Lop-eared rabbits represented 30 of 69 cases. Upper respiratory signs (48 of 69 [69.6%]) and dental-related disorders (21 of 69 [31.9%]) were primary complaints. Rhinitis (49 of 69 [71.0%]), sinusitis (50 of 69 [72.5%]), and both (40 of 69 [60.0%]) were most diagnosed, with turbinate destruction (48 of 69 [69.6%]) and alveolar bone loss of adjacent teeth (51 of 69 [73.9%]) being common findings. Sinusitis was most common in the ventral (48 of 50 [96.0%]) and dorsal (33 of 50 [66.0%]) recesses of the maxillary sinus. Multiple CT variables were significantly correlated (P < .05); of those, maxillary alveolar bone loss of the incisor teeth and the second premolar tooth were, respectively, correlated with rhinitis grade and with sinusitis and sinusitis grade within the ventral recess of the maxillary sinus (P < .001).

Conclusions: Computed tomographic evaluation allowed characterization of nasal and paranasal disease in rabbits and the association of rhinitis, sinusitis, and dental disease.

Clinical relevance: The correlation between the maxillary dentition, rhinitis, and sinusitis highlights the need for thorough evaluation in CT of the teeth in rabbits with upper respiratory signs.

目的:描述家兔鼻腔和副鼻腔疾病的 CT 发现和流行病学特征:描述兔子(Oryctolagus cuniculus)鼻腔和副鼻腔疾病的 CT 结果和流行病学特征:方法:对 2004 年至 2024 年期间接受头颅 CT 检查并发现与鼻腔/副鼻腔或上颌牙齿疾病一致的兔子进行电子检索。记录病史、信号和体格检查结果,并重新回顾评估鼻腔、副鼻窦和附近相关解剖结构的变化证据。数据分析采用描述性统计、顺序混合逻辑回归和相关分析:结果:共审查了来自 69 只兔子的 100 项研究。69 只病例中有 30 只为兔耳病兔。上呼吸道症状(69 只中的 48 只 [69.6%])和牙齿相关疾病(69 只中的 21 只 [31.9%])是主要病症。鼻炎(69 只中有 49 只 [71.0%])、鼻窦炎(69 只中有 50 只 [72.5%])和鼻窦炎(69 只中有 40 只 [60.0%])是最常见的诊断结果,鼻甲破坏(69 只中有 48 只 [69.6%])和邻近牙齿的牙槽骨脱落(69 只中有 51 只 [73.9%])是常见的检查结果。上颌窦炎最常见于上颌窦的腹侧凹陷(50 例中有 48 例 [96.0%])和背侧凹陷(50 例中有 33 例 [66.0%])。多个 CT 变量存在明显相关性(P < .05);其中,上颌切牙和第二前磨牙的牙槽骨缺损分别与鼻炎等级和上颌窦腹侧凹的鼻窦炎和鼻窦炎等级相关(P < .001):计算机断层扫描评估可确定兔子鼻腔和副鼻腔疾病的特征,以及鼻炎、鼻窦炎和牙齿疾病之间的关联:临床相关性:上颌牙齿、鼻炎和鼻窦炎之间的相关性强调了对有上呼吸道症状的兔子进行牙齿 CT 全面评估的必要性。

Objective: Evaluate the incidence of Borrelia burgdorferi in cases of equine nuchal bursitis (NB) and investigate the relationship between elevated serum outer surface protein A (OspA) antibodies and the molecular identification of B burgdorferi in bursal tissue or synovial fluid. Additionally, describe clinical cases and compare the histologic changes in NB with and without detection of B burgdorferi.

Methods: This was a retrospective multicenter cohort study (2013 to 2022). Medical records from horses with a diagnosis of NB and B burgdorferi PCR testing on NB tissue or synovial fluid were reviewed. The study population included 11 horses with a postmortem diagnosis of NB, 19 horses from the northeastern US with an antemortem diagnosis of B burgdorferi PCR-positive NB, and 15 healthy controls without evidence of NB and unvaccinated for B burgdorferi. Where serum was available, Lyme multiplex assay results were compared with controls and ELISAs targeting individual B burgdorferi antigens were performed. Histologic findings in nuchal bursa tissue were compared between NB cases with and without B burgdorferi PCR detection.

Results: Serum OspA antibody values in B burgdorferi-positive NB cases (n = 13) were significantly elevated (P < .001) compared to controls (15), and OspA was the predominant antigen detected by ELISA (8). Histopathology did not vary between NB cases with (n = 9) and without (6) B burgdorferi PCR detection.

Conclusions: The presence of B burgdorferi in the nuchal bursa of horses is associated with increased serum OspA antibodies.

Clinical relevance: The role of B burgdorferi in equine NB may be underestimated, and targeted therapy requires investigation.

Objective: To evaluate field-applicable cooling methods for treatment of exercise-induced hyperthermia in dogs.

Methods: In this randomized, crossover study from June 27, 2023, to July 24, 2023, 12 working dogs exercised for 10 minutes until core body temperature reached 40.6 °C or above or ≥ 2 signs of heat stress were observed. Four different cooling protocols were evaluated: (1) neck chemical ice packs (2), (2) a wet (22 °C) neck towel, (3) wet (22 °C) axillae towels, or (4) voluntary head immersion ("dunking") into (22 °C) water. After intervention, dogs rested and were monitored for 40 minutes.

Results: The dunking protocol, which included limited water ingestion, produced the lowest mean core temperature in the initial 5 minutes after exercise, in the subsequent 35 minutes during which dogs cooled to baseline temperature and was the only protocol to prevent the initial postexercise temperature rise. All methods resulted in return to baseline temperature.

Conclusions: Trained voluntary head dunk with limited water ingestion results in rapid cooling in field situations of exercise-induced hyperthermia in dogs with normal mental status and ability to pause panting.

Clinical relevance: "Cool first, transport second" reduces morbidity and mortality of acute heat injury. When whole-body water immersion is not an option, the trained voluntary head dunk in mentally appropriate dogs prevents postexercise rise and rapidly reduces core body temperature within the first 5 minutes. Alternatively, allowing the dog to drink controlled amounts of cool water and pouring water on the dog's head may provide some benefit but warrants further study.

目的评估用于治疗犬运动性高热的现场适用降温方法:在 2023 年 6 月 27 日至 2023 年 7 月 24 日进行的这项随机交叉研究中,12 只工作犬运动了 10 分钟,直到核心体温达到或超过 40.6 °C,或观察到≥ 2 个热应激迹象。对四种不同的降温方案进行了评估:(1) 颈部化学冰袋(2);(2) 湿(22 °C)颈部毛巾;(3) 湿(22 °C)腋下毛巾;或 (4) 自愿将头部浸入(22 °C)水中("浸泡")。干预结束后,狗休息并接受 40 分钟的监测:结果:"浸水 "方案包括有限的进水,在运动后最初 5 分钟内产生的平均核心温度最低,在随后的 35 分钟内,狗的体温降至基线温度,并且是唯一一种防止运动后体温上升的方案。所有方法都会导致体温恢复到基线温度:结论:在运动诱发高热的现场情况下,对于精神状态正常且能暂停喘气的狗,训练有素的自愿头部灌水和有限的进水可使其迅速降温:临床意义:"先降温,后运输 "可降低急性热损伤的发病率和死亡率。当无法选择全身浸水时,可对精神正常的犬进行训练,让其自愿头部浸水,以防止运动后体温升高,并在最初 5 分钟内迅速降低核心体温。另外,让狗饮用一定量的凉水并将水倒在狗的头部也可能会带来一些好处,但还需要进一步研究。
