普通骨板内固定治疗玩具犬桡尺骨骨折的回顾性分析

本试验旨在评估普通骨板内固定治疗玩具犬桡尺骨骨折的临床效果及并发症。回顾了中国农业大学动物医院使用普通骨板（圆洞骨板或兽医可剪裁骨板）开放式复位和内固定治疗桡尺骨骨折的玩具犬的病历记录,并对这些病例进行回访。入选病例满足以下条件：体重不超过7 kg;回访时间大于12个月;病例信息记录完整。结果显示：共纳入63只犬的64例桡尺骨骨折,49例（76.6%）术后无跛行,7例（10.9%）术后勉强可见到跛行,6例（9.3%）存在轻度跛行,2例（3.1%）存在中度跛行。严重并发症的发生率是6.3%,轻微并发症的发生率是27%。试验表明,普通骨板内固定能有效治疗玩具犬桡尺骨骨折,该方法临床效果良好,且严重并发症发生率低。     

阿莫西林在兽医临床的应用研究进展

阿莫西林（amoxicillin,AMO）是一种半合成青霉素类抗生素,具有耐酸性强、杀菌效果好、抗菌谱广、易溶于水、剂型多样等优点,被广泛应用于兽医临床。为进一步明确阿莫西林在兽医临床的应用效果,结合国内外研究现状,从理化特性、抗菌机理、安全性以及在治疗动物细菌感染性疾病中的应用等方面进行综述,以期为阿莫西林在兽医临床的科学合理使用提供参考。     

猫下泌尿道综合征

猫下泌尿道综合征（FLUTD）是猫最常见的疾病之一,因其发病率高、病因复杂、确诊困难、治疗后易复发等特点,逐渐成为猫科疾病的研究热点。FLUTD包括多种疾病类型,精准治疗、合理预防已成为科学防控该疾病的关键。本文从FLUTD的分类、流行病学及风险因子、发病机制、临床症状、诊断和防治对该综合征进行综述,以推动猫下泌尿道综合征的深入研究及临床诊疗的发展。

Clinical assessment and grading of back pain in horses

BackgroundThe clinical presentation of horses with back pain (BP) vary considerably with most horse''s willingness to take part in athletic or riding purpose becoming impossible. However, there are some clinical features that are directly responsible for the loss or failure of performance.ObjectivesTo investigate the clinical features of the thoracolumbar region associated with BP in horses and to use some of the clinical features to classify equine BP.MethodsTwenty-four horses comprised of 14 with BP and 10 apparently healthy horses were assessed for clinical abnormality that best differentiate BP from normal horses. The horses were then graded (0–5) using the degree of pain response, muscular hypertonicity, thoracolumbar joint stiffness and overall physical dysfunction of the horse.ResultsThe common clinical features that significantly differentiate horses with BP from non-BP were longissimus dorsi spasm at palpation (78.6%), paravertebral muscle stiffness (64.3%), resist lateral bending (64.3%), and poor hindlimb impulsion (85.7%). There were significantly (p < 0.05) higher scores for pain response to palpation, muscular hypertonicity, thoracolumbar joint stiffness and physical dysfunction among horses with BP in relation to non-BP. A significant relationship exists between all the graded abnormalities. Based on the cumulative score, horses with BP were categorized into mild, mild-moderate, moderate and severe cases.ConclusionsBP in horse can be differentiated by severity of pain response to back palpation, back muscle hypertonicity, thoracolumbar joint stiffness, physical dysfunctions and their cumulative grading score is useful in the assessment and categorization of BP in horses.     

A Bayesian approach to the accuracy of clinical observations

The accuracy of clinical observations was estimated using Bayesian latent-class models with two or more independent tests. Four veterinarians carried out systematic independent clinical examinations on 155 pigs in three herds. Based on the results of binary recordings of clinical observations on dullness, poor body condition (PBC), skin lesions, lameness, respiratory disease, and diarrhea, a latent disease state for each clinical disease was estimated using Gibbs sampling.

The accuracy of the clinical observations differed for the four observers and for different clinical signs. Population parameters were estimated from a Bayesian hierarchical model, and the accuracy of a random observer was calculated. We concluded that the accuracy of the veterinarians in this study substantiated the need to pursue more-precise definitions of the clinical findings and that larger sample sizes would be needed to provide reasonable variance estimates. Finally, we concluded that the uncertainty in the clinical decision-making process (starting with the clinical examination) needs to be represented fully.     

猫传染性腹膜炎研究进展

猫传染性腹膜炎是一种全身性、致死性的病毒性疾病,为幼猫和青年猫死亡的主要原因之一。近年来,该病在世界各地广泛流行,并呈一定的上升趋势。越来越多的学者对其进行了研究与探索,但其致病与免疫机制仍未完全清楚。本文从病原学、发病机制、流行病学、临床症状、诊断与治疗以及免疫与预防等方面对猫传染性腹膜炎进行全面的阐述,为该病的科学诊治与防控提供参考和指导。
