Objectives: To evaluate evidence of Malassezia overgrowth following successful topical antibacterial monotherapy of refractory canine bacterial otitis using semi-quantitative cultures.

Materials and methods: Twenty-nine dogs with bacterial otitis were treated topically with either fluoro-quinolone [0.5% enrofloxacin (18 dogs, 19 treatment events, 25 ears) or 0.1% marbofloxacin (1 ear), with 0.1% dexamethasone] ("FQ") SID, or 143 mg/mL piperacillin/18 mg/mL tazobactam ("PT") BID (11 dogs, 14 treatment events, 19 ears) for 8 to 36 days (mean 20 days). At visits 1 (V1) and 2 (V2), ear swab tips were washed in PBS + Triton X-100 and serial dilutions spread-plated onto blood, MacConkey (37°C, 48 hours) and modified Dixon's agar (32°C, 14 days) to generate semiquantitative counts. Microbes were identified by phenotype and MALDI-TOF.

Results: Prior to treatment, Pseudomonas aeruginosa was isolated alone or in combination with other bacteria in 14 FQ-treated ears and 18 PT-treated ears; the next most frequent bacteria were Streptococcus canis (8 FQ, 2 PT) and Staphylococcus pseudintermedius (8 FQ, 1 PT). The proportions of dogs' ears (excluding cross-over treatments and contra-lateral affected ears) from which bacteria were isolated were significantly reduced by treatment with both FQ (V1, 13/15; V2, 5/15) and PT (V1, 14/14; V2, 2/14). The proportions of dogs' ears from which yeasts (Malassezia pachydermatis, Candida spp.) were isolated were significantly increased by treatment in dogs treated with PT (V1, 1/14; V2, 14/14) but not FQ (V1, 3/15; V2, 6/15).

Clinical significance: Otitis cases that receive potent antibacterial monotherapy must be monitored for yeast overgrowth.

摘要使用半定量培养法评估犬细菌性中耳炎局部抗菌单药治疗成功后马拉色菌过度生长的证据:29 只患有细菌性中耳炎的狗接受了氟喹诺酮[0.5% 恩诺沙星(18 只狗,19 次治疗,25 耳)或 0.1% 马勃沙星(1 耳),加 0.1% 地塞米松]("FQ")SID 或 143 毫克/毫升哌拉西林/18 毫克/毫升他唑巴坦("PT")BID(11 只狗,14 次治疗,19 耳)局部治疗,疗程为 8 到 36 天(平均 20 天)。在第 1 次(V1)和第 2 次(V2)检查时,用 PBS + Triton X-100 冲洗耳拭子头,并将连续稀释液涂布在血液、麦康凯琼脂(37°C,48 小时)和改良狄克逊琼脂(32°C,14 天)上,以生成半定量计数。微生物通过表型和 MALDI-TOF 进行鉴定:治疗前,在 14 只经 FQ 处理的耳朵和 18 只经 PT 处理的耳朵中单独或与其他细菌混合分离出铜绿假单胞菌;其次最常见的细菌是犬链球菌(8 只经 FQ 处理,2 只经 PT 处理)和假中间葡萄球菌(8 只经 FQ 处理,1 只经 PT 处理)。使用 FQ(V1,13/15;V2,5/15)和 PT(V1,14/14;V2,2/14)治疗后,狗耳(不包括交叉治疗和对侧患耳)中分离出细菌的比例显著降低。在使用 PT(V1,1/14;V2,14/14)而非 FQ(V1,3/15;V2,6/15)治疗的狗耳中,分离出酵母菌(马拉色菌、念珠菌属)的比例明显增加:临床意义:接受强效抗菌单药治疗的耳炎病例必须监测酵母菌的过度生长。

Objectives: To evaluate haemodynamic parameters and ultrasonographic measurements of the caudal vena-cava-to-aorta ratio at the splenorenal view in canine cardiac tamponade before and 30 minutes after pericardiocentesis.

Materials and methods: Dogs presenting with cardiac tamponade at two veterinary hospitals were included. Triage examination, noninvasive systolic arterial blood pressure, shock index, venous lactatemia and POCUS results were recorded at admission and 30 minutes after pericardiocentesis.

Results: This prospective observational study included 22 dogs, and all had an increased caudal vena-cava-to-aorta ratio. After pericardiocentesis, there were significant changes in vital signs, including a decrease in the median heart rate by 42.1%, a decrease in the median respiratory rate by 40.1%, and an increase in the median rectal temperature from 37.8°C (range: 35.6 to 39.2) to 38.1°C ( 36.1 to 38.7). In regards of hemodynamic parameters, the median systolic arterial pressure increased significantly by 23.2%, the shock index decreased significantly by 52.8%, the median lactate level decreased significantly from 6.1 mmol/L (1.4 to 14.7) to 3.6 mmol/L (1.1 to 13.6), and the median caudal vena-cava-to-aorta ratio decreased significantly by 37.5%, from 1.76 (1.35 to 2.13) to 1.12 (0.91 to 1.51).

Clinical significance: This study demonstrated an increased caudal vena-cava-to-aorta ratio in dogs with cardiac tamponade and a rapid haemodynamic improvement in dogs with cardiac tamponade within 30 minutes  of the pericardiocentesis, resulting in excellent short-term prognosis.

目的评估犬心脏填塞在心包穿刺术前和穿刺术后 30 分钟内的血流动力学参数以及脾脏视角下尾腔静脉与主动脉比率的超声测量结果:纳入在两家兽医院就诊的心脏填塞的犬只。记录入院时和心包穿刺术后 30 分钟的分诊检查、无创收缩期动脉血压、休克指数、静脉乳酸血症和 POCUS 结果:这项前瞻性观察研究共纳入了 22 只犬,所有犬的尾静脉-腔-主动脉比值都有所增加。心包穿刺术后,生命体征发生了显著变化,包括心率中位数下降了42.1%,呼吸频率中位数下降了40.1%,直肠温度中位数从37.8°C(范围:35.6-39.2)升至38.1°C(36.1-38.7)。在血液动力学参数方面,中位收缩动脉压显著上升了 23.2%,休克指数显著下降了 52.8%,中位乳酸水平从 6.1毫摩尔/升(1.4至14.7)显著降至3.6毫摩尔/升(1.1至13.6),尾静脉-腔-主动脉比值中位数从1.76(1.35至2.13)显著降至1.12(0.91至1.51),下降了37.5%:这项研究表明,心脏填塞犬的尾静脉-腔-主动脉比值增加,心脏填塞犬的血流动力学在心包穿刺后30分钟内迅速改善,因此短期预后良好。

Objectives: This study aims to report on the clinical magnetic resonance imaging, histological features, treatment options and outcomes of spinal ependymomas in dogs.

Materials and methods: Retrospective evaluation of medical records from dogs histologically confirmed spinal ependymomas with clinical presentations, magnetic resonance imaging findings, histological aspects, treatment options and outcomes.

Results: Eight dogs presented with acute to subacute onset of para- or tetraparesis. Magnetic resonance imaging findings included intramedullary oval-shaped space-occupying lesions that appeared hyperintense on T2-weighted images isointense on T1-weighted images and exhibited marked homogeneous or ring contrast enhancement. A peculiar feature, previously described only in human ependymomas, was observed in three patients - a T2-weighted hypointense rim, termed hemosiderin cap sign. Haematomyelia with necrotic foci was observed in one dog. Surgery, when performed, enabling a definitive intra-vitam diagnosis. Histological examination revealed that rosettes and pseudo-rosettes as disposition of neoplastic cells were the most common features reported. Furthermore, cerebrospinal fluid metastases were identified in one case.

Clinical significance: Clinical and histopathological findings in our case series were consistent with those previously reported in the literature. Magnetic resonance imaging features were fairly typical and highly suggestive of spinal ependymomas. The hemosiderin cap sign may aid in the presumptive intra-vitam diagnosis of these rare spinal tumours. Additionally, we described cerebrospinal fluid spread of neoplastic cells and subsequent multifocal or metastasis presentations. Surgery offered a dual benefit by facilitating intra-vitam diagnosis and, in some cases, extending survival time.

研究目的本研究旨在报告犬脊柱上皮瘤的临床磁共振成像、组织学特征、治疗方案和结果:回顾性评估经组织学证实为脊柱外胚瘤犬只的病历,包括临床表现、磁共振成像结果、组织学方面、治疗方案和结果:八只狗出现急性或亚急性副瘫痪或四肢瘫痪。磁共振成像结果显示,髓内椭圆形占位性病变在T2加权图像上呈高密度,在T1加权图像上呈等密度,并表现出明显的均质或环状对比度增强。在三名患者身上还观察到一个以前仅在人类脑外胚瘤中描述过的特殊特征--T2 加权低密度边缘,即血色素帽征。在一只狗身上观察到了带有坏死灶的血肌瘤。在进行手术时,可以明确病灶内的诊断。组织学检查显示,报告的最常见特征是瘤细胞呈莲座状和假性莲座状分布。此外,在一个病例中还发现了脑脊液转移:临床意义:我们的病例系列中的临床和组织病理学结果与之前文献报道的一致。磁共振成像特征相当典型,高度提示脊髓上皮瘤。血色素帽征可帮助推测这些罕见脊柱肿瘤的椎管内诊断。此外,我们还描述了肿瘤细胞的脑脊液扩散以及随后的多灶或转移表现。手术具有双重益处,不仅有助于病灶内诊断,在某些情况下还能延长生存时间。

Objectives: To determine the difference in complication rate, gastrointestinal grade and requirement for ongoing medical and/or surgical management following hiatal hernia repair in dogs with and without gastropexy.

Materials and methods: Clinical records were reviewed retrospectively for dogs that had undergone surgical hiatal hernia repair at two veterinary referral centres between April 2012 and March 2022. Pre-operative grading of gastrointestinal signs and brachycephalic obstructive airway syndrome was performed. All dogs had an oesophagopexy and phrenoplasty. Referring primary veterinary practices and clients were contacted to obtain follow-up information. Fisher's exact tests and Mann Whitney tests were used to assess pre- and intra-operative similarities between groups. Wilcoxon signed rank tests were used to determine the changes in gastrointestinal grade at short- (<6 months) and long-term (>6 months) follow-up.

Results: Forty-one dogs which underwent oesophagopexy and phrenoplasty were included. Fifteen dogs had no gastropexy performed and 26 dogs had left-sided gastropexy performed. Dogs that underwent gastropexy (n=8, 29%, 95% CI: 13 to 51%) were significantly more likely to require further surgery related to the initial surgery or persistence of gastrointestinal signs compared to dogs that had no gastropexy (n=0, 0%, 95% CI: 0 to 18%) . This difference was not significant when dogs which had further surgery to address brachycephalic obstructive airway syndrome were excluded. Gastrointestinal grade significantly improved for both groups at both short- and long-term follow-up. There was no significant difference in overall complication rate, gastrointestinal grade or requirement for further medical treatment between groups.

Clinical significance: A left-sided gastropexy is not required for successful surgical repair of hiatal hernia in dogs provided oesophagopexy and phrenoplasty are performed.

目的:确定犬食管裂孔疝修补术后并发症发生率、胃肠道等级以及持续药物和/或手术治疗的要求:确定有胃镜和没有胃镜的犬食道裂孔疝修补术后并发症发生率、胃肠道等级和持续药物和/或手术治疗要求的差异:回顾性审查了 2012 年 4 月至 2022 年 3 月期间在两家兽医转诊中心接受食管裂孔疝修补手术的犬只的临床记录。术前对胃肠道体征和手足阻塞性气道综合征进行了分级。所有犬只都进行了食道和膈成形术。我们联系了转诊的初级兽医诊所和客户,以获得后续信息。费雪精确检验和曼-惠特尼检验用于评估各组之间术前和术中的相似性。Wilcoxon 符号秩检验用于确定短期(6 个月)随访时胃肠道等级的变化:结果:纳入了 41 只接受食道和膈肌成形术的狗。其中 15 只狗没有进行胃镜手术,26 只狗进行了左侧胃镜手术。与没有进行胃切除术的狗(n=0,0%,95% CI:0 至 18%)相比,进行了胃切除术的狗(n=8,29%,95% CI:13 至 51%)更有可能因初次手术或胃肠道症状持续存在而需要进一步手术。如果不包括为治疗肱鼻阻塞性气道综合征而接受进一步手术的犬只,这一差异并不显著。在短期和长期随访中,两组犬的胃肠道等级均有明显改善。两组之间在总并发症发生率、胃肠道等级或进一步治疗要求方面没有明显差异:临床意义:如果进行了食道成形术和膈成形术,狗的食道裂孔疝手术修复不需要进行左侧胃切除术。

Objectives: Recently, tissue motion annular displacement by speckle tracking has been shown to be a reliable method for evaluating deformation of the left atrium in healthy dogs. The aim of this study was to investigate whether tissue motion annular displacement is a feasible alternative method for studying left atrial function.

Materials and methods: One hundred healthy dogs were included. Left atrial function was assessed by tissue motion annular displacement, which was correlated to the left atrial strain and biplane area-length method-derived volumes. Left atrial reservoir function was evaluated by left atrial global tissue motion annular displacement, global left atrial strain and left atrial emptying fraction, while left atrial systolic tissue motion annular displacement and left atrial ejection fraction were used to assess left atrial systolic function.

Results: A statistically significant association between body weight and the dependent variables others than age was found. Indexed global and systolic tissue motion annular displacement decreased as body weight increased. Global iTMAD_AIIometric (mm/∛kg) showed a moderate, positive correlation with left atrial emptying fraction and with global left atrial strain. Systolic iTMAD_AIIometric (mm/∛kg) showed a moderate correlation with left atrial ejection fraction. Coefficients of variation for the intraobserver and interobserver analyses were 8.3% and 20.3% for global and 10.5% and 18.9% for systolic tissue motion annular displacement, respectively.

Clinical significance: Tissue motion annular displacement is a feasible and simple method for the evaluation of left atrial function. Our study documented the effects of body weight on left atrial tissue motion annular displacement, indicating that tissue motion annular displacement must be indexed to body weight. No influence of age or heart rate was observed on tissue motion annular displacement.

目的:最近,通过斑点追踪进行组织运动环位移已被证明是评估健康犬左心房变形的一种可靠方法。本研究旨在探讨组织运动环位移是否是研究左心房功能的另一种可行方法:研究对象包括 100 只健康犬。通过组织运动环位移评估左心房功能,该位移与左心房应变和双平面面积-长度法得出的体积相关。左心房储库功能通过左心房整体组织运动环位移、左心房整体应变和左心房排空分数进行评估,而左心房收缩组织运动环位移和左心房射血分数则用于评估左心房收缩功能:结果:体重与除年龄以外的其他因变量之间存在统计学意义上的明显联系。随着体重的增加,指数化的整体和收缩期组织运动环位移量减少。总体 iTMAD_AIIometric(毫米/∛千克)与左心房排空分数和总体左心房应变呈中度正相关。收缩期 iTMAD_AIIometric(mm/∛kg)与左心房射血分数呈中度相关。观察者内和观察者间分析的变异系数分别为:整体变异系数为 8.3% 和 20.3%,收缩期组织运动环位移变异系数为 10.5% 和 18.9%:组织运动环位移是评估左心房功能的一种简单可行的方法。我们的研究记录了体重对左心房组织运动环位移的影响,表明组织运动环位移必须与体重挂钩。年龄和心率对组织运动环位移没有影响。

Type III von Willebrand disease is a rare coagulopathy, with published reports only existing for four canine breeds - Dutch Kooiker Hounds, Shetland Sheepdogs, Chesapeake Bay Retrievers and Scottish Terriers. A 2-year and 9-month-old male neutered standard dachshund was presented for hypovolaemic shock and a ventral neck mass. One previous bleeding episode following routine castration was reported. The patient's packed cell volume fell from 27% to 15% during hospitalisation, and computed tomography identified changes to the ventral neck consistent with fluid accumulation, assumed to represent haemorrhage. A further, similar lesion was identified within the cranial mediastinum. The patient was managed with a combination of isotonic crystalloids (Hartmann's solution), synthetic colloid (Geloplasma), alongside administration of blood products (packed red blood cells and fresh frozen plasma). A Von Willebrand factor antigen assay confirmed Type III von Willebrand disease. The patient made a full recovery. This report is the first to describe Type III von Willebrand disease in a standard dachshund.

III 型 von Willebrand 病是一种罕见的凝血病,目前仅有关于荷兰库伊克猎犬、设德兰牧羊犬、切萨皮克湾寻回犬和苏格兰梗犬这四个犬种的公开报道。一只 2 岁零 9 个月大的雄性阉割标准腊肠犬因低血容量休克和颈部腹侧肿块就诊。据报告,该犬曾在例行阉割后发生过一次出血。住院期间,患者的充盈细胞容积从 27% 降至 15%,计算机断层扫描发现腹侧颈部有积液变化,推测为出血。在颅纵隔内还发现了一个类似的病灶。患者接受了等渗晶体液(哈特曼溶液)、合成胶体(凝胶体)以及血液制品(红细胞和新鲜冰冻血浆)的综合治疗。冯-维勒布兰德因子抗原检测证实了 III 型冯-维勒布兰德病。患者完全康复。该报告首次描述了标准腊肠犬的 III 型 von Willebrand 病。

Patient 1 was seen for severe pelvic limb lameness and evaluated radiographically and via computed tomography. A diagnosis of femoral head osteochondritis dissecans was obtained. The diagnosis was confirmed arthroscopically and treated with flap removal and abrasion arthroplasty. A micro-total hip arthroplasty was performed 4 weeks later. Patient 2 was also seen for severe pelvic limb lameness and evaluated radiographically. A suspected large osteochondritis dissecans lesion was present. This was confirmed grossly during a total hip arthroplasty procedure and the femoral head submitted for histopathology. In patient 1, the lameness improved from non-weight-bearing to mild lameness at re-evaluation 4 weeks post-operatively. Due to the extent of the lesion, which was confirmed as osteochondritis dissecans by a team of pathologists, revision to micro-total hip arthroplasty was performed. Surgery was uneventful and at 12 weeks post-operatively the patient was fully weight-bearing with no lameness and normal limb function. In patient 2, the lameness immediately resolved after successful management via uncomplicated total hip arthroplasty. Follow-up for both patients at the time of publication exceeds 3 years.

患者 1 因骨盆肢体严重跛行就诊,并接受了放射学和计算机断层扫描评估。诊断结果为股骨头骨软骨炎。经关节镜确诊后,患者接受了皮瓣切除和磨损关节成形术。4 周后进行了显微全髋关节置换术。患者 2 也因骨盆肢体严重跛行就诊,并进行了放射学评估。疑似大骨软骨炎(osteochondritis dissecans)病变。在进行全髋关节置换术时,大体上证实了这一点,并将股骨头送去进行组织病理学检查。患者1的跛行情况在术后4周再次评估时从不能负重改善为轻度跛行。由于病变范围较大,病理学家小组确认其为骨软骨炎,因此对其进行了翻修,改为微全髋关节置换术。手术很顺利,术后12周,患者完全负重,没有跛行,肢体功能正常。患者2的跛行症状在通过无并发症的全髋关节置换术成功治疗后立即得到缓解。截至本报告发表时,两名患者的随访时间均已超过 3 年。
