Ischemic neuromyopathy due to peripheral arterial embolization of an adenocarcinoma in a cat

A case of peripheral arterial tumor embolization in a cat is described. The cat presented with signs of aortic thromboembolism, including decreased peripheral pulse quality, pallor, and coolness of the distal limbs, as well as proprioceptive deficits. Thoracic radiographs revealed a cavitary lung mass; echocardiography was unremarkable. Cytologic evaluation of aspirates of the mass suggested malignancy. The left hindlimb was amputated, and histopathology confirmed embolization of an adenocarcinoma. Although rare, peripheral arterial tumor embolization should be considered as a differential in cats presenting with signs of thromboembolic disease.     

Effect of Repeated Arthrocentesis on Cytologic Analysis of Synovial Fluid in Dogs

Background: Serial arthrocentesis and synovial fluid examination can be used to monitor treatment efficacy in immune-mediated polyarthritis (IMPA), but whether this procedure induces inflammation that interferes with test result interpretation is unknown.
Objectives: The aim of this study was to determine the effect of repeated arthrocentesis on synovial fluid cytology in healthy dogs.
Animals: Nine healthy client-owned dogs.
Methods: Prospective study. Arthrocentesis was performed under sedation on 4 joints (both carpi, 1 tarsus, 1 stifle) on each dog every 3 weeks, a total of 4 times. Automated cell counts were done on stifle fluid, smears were made, and differential cell counts done on smears from all joints. Slides were evaluated microscopically for erythrocyte numbers, total nucleated cell count, differential cell count, and cell morphology. Data were analyzed by 2-way analysis of variance.
Results: A total of 144 synovial fluid samples were examined. Repeated arthrocentesis was not associated with increases in synovial fluid neutrophil numbers. Mild mononuclear inflammation was detected in 13 samples from 6 dogs.
Conclusions and Clinical Importance: Serial arthrocentesis at 3-week intervals can rarely be associated with mild mononuclear joint inflammation, but does not appear to induce neutrophilic inflammation, at least in healthy dogs, and can be useful to monitor treatment response in canine IMPA.     

重新评估母猪妊娠期日粮的纤维营养

养猪生产者有机会通过给妊娠母猪饲喂富含纤维的日粮来维持和改善其繁殖性能。 概述：笔者查阅了1975～2007年发表的24篇报告,以确定给妊娠母猪饲喂高水平纤维型日粮所产生的总体影响。母猪及其产仔性状通过每个试验内各个处理的母猪窝数来权衡。总体而言,母猪妊娠阶段可以安全地采食高纤维日粮,而几乎不会带来的有害影响。母猪采食高水平纤维型日粮后产生的积极影响可明显地反映在窝产仔数（提高0.2～0.6头/窝）和哺乳期的采食量（提高0.5～0.8lb/d）上,但在母猪持续采食高水平纤维型日粮后的第2个繁殖周期前,这些影响并不是非常显著。通过饲喂高水平纤维型日粮,可能有助于确保母猪及其所产仔猪的生产性能得到改善,但纤维类饲料必须在母猪配种之前加入所喂的日粮中。
