Use of ultrasound-guided autologous bone marrow transfer for treatment of suspensory ligament desmitis in 30 race horses (2003–2010)
Use of ultrasound-guided autologous bone marrow transfer for treatment of suspensory ligament desmitis in 30 race horses (2003–2010):
Objective
To evaluate the racing performance of horses that underwent ultrasound-guided intralesional injection of autologous bone marrow aspirate for treatment of selected forelimb suspensory ligament (body or branch) core lesions.
Design
Retrospective cohort study of 13 Standardbred and 17 Thoroughbred race horses.
Methods
Autologous bone marrow aspirated from the sternebrae was injected, under ultrasound guidance, into suspensory ligament core lesions (body or branch). Racing records were reviewed for a comparison of performance before and after surgery.
Results
Of the 13 Standardbreds, 9 (69%) had one or more starts within the follow-up period and 9 (69%) had five or more starts. Of the 17 Thoroughbreds, 15 (88%) had one or more starts within the follow-up period and 12 (71%) had five or more starts. Eight Standardbred horses had at least one start both before and after surgery. Earnings per start did not differ significantly between the three starts immediately after surgery compared with the three starts immediately prior to surgery. Thirteen Thoroughbred horses had at least one start both before and after surgery. Earnings per start were less for the three starts immediately after surgery compared with the three starts immediately prior to surgery.
Conclusions and clinical relevance
A horse with a core lesion in the branch or body of the suspensory ligament has a good prognosis for return to racing after treatment with intralesional injection of bone marrow aspirate.

Case–Control Study of a Multistate Equine Herpesvirus Myeloencephalopathy Outbreak
Case–Control Study of a Multistate Equine Herpesvirus Myeloencephalopathy Outbreak:
Background
A large multistate outbreak of equine herpesvirus myeloencephalopathy (EHM) occurred in May 2011 among horses that participated in a competitive event.
Objective
To identify EHM risk factors among horses with a common exposure venue.
Animals
A total of 123 horses: 19 horses with EHM, 14 equine herpesvirus-1 cases with no reported neurologic signs, and 90 control horses.
Methods
EHM case survey data were compared with data from EHV-1 cases with no neurologic signs and healthy controls using univariable and multivariable methods.
Results
Significant factors associated with higher risk for EHM compared with EHV-1 cases with no neurologic signs were (1) greater number of biosecurity risks at the event, (2) female sex, (3) increasing number of classes competed in at the event, and (4) an interaction between sex and number of classes competed in. In the EHM versus controls comparison, in addition to sex and biosecurity risks, factors associated with higher EHM risk included EHV-1 vaccination in the 5 weeks before the event and increasing number of events attended in April 2011; zinc dietary supplementation was associated with decreased risk. An interaction between sex and the number of events attended in April 2011 also was significant.
Conclusions and Clinical Importance
Findings from this study suggest that dietary zinc supplementation may be associated with decreased risk of EHM. Several factors were associated with increased risk of EHM. Additional investigations of factors associated with risk of EHM are warranted to evaluate the importance of these factors in this complex disease of horses.
Management of Chronic Diarrhea in an Adult Horse
Management of Chronic Diarrhea in an Adult Horse: Abstract: Chronic diarrhea could be a challenge from both the diagnostic and therapeutic point of view. This case report will discuss the clinical approach to the evaluation of chronic diarrhea with the production of free fecal water in an adult horse. The discussion of this case report may provide further information and describe a possible therapeutic option with sulfasalzine, focusing on the nutritional management of chronic diarrhea in adult horses. Nutritional management could be of higher importance for horses that suffer from this problem because it improves the well-being of the hindgut environment. In the present case report, motility abnormalities were identified without other physiological disturbances of colonic function or a decrease in body weight, and the priority was the following: (1) rebalancing of the diet to the real nutritional requirements of the patient, (2) avoiding excess carbohydrate from both forage and concentrate, (3) selecting the right proportion between good quality first-cut meadow hay and grounded and pelleted meadow hay that helps to reduce mechanical and physical load of the colon and could help in the formation of more homogeneous digesta, (4) reducing the stress with adequate feed consumption time, meal size, and time spent in a overgrazed paddock, and (5) increasing the proportion of omega-3 fatty acids in the diet. With the nutritional plan and management and the initial use of sulfasalazine, the horse maintained a good quality of the feces with a reduced or absent production of the free fecal water.
Determining Treatment to Control Two Multidrug-Resistant Parasites on a Texas Horse Farm
Determining Treatment to Control Two Multidrug-Resistant Parasites on a Texas Horse Farm: Abstract: A study was undertaken at the Texas A&M Horse Center to evaluate and compare the effectiveness of three anthelmintics—ivermectin, fenbendazole, and a combination of ivermectin and pyrantel pamoate—on fecal egg count reductions of cyathostomes and Parascaris equorum in 30 naturally infected foals. The foals were randomized into three treatment groups, with individuals being rerandomized after each 8-week observation period. The treatments of ivermectin and fenbendazole were given at the manufacturer's recommended doses, and the pyrantel treatment was given at two times the manufacturer's recommended dose. Fecal egg counts were performed at the time of treatment and at 2-week intervals after treatment for a total of 8 weeks. Each foal received a total of three treatments during the course of the study. Fecal egg counts were performed by a modified McMaster's test, with a sensitivity of 25 eggs per gram of feces, and by the modified Wisconsin double centrifugal flotation technique, with a sensitivity of 0.2 eggs per gram of feces. Fecal egg reduction percentages were calculated. Analysis of the results showed that ivermectin, either used alone or with pyrantel, was a more effective anthelmintic for cyathostome (small strongyle) control than fenbendazole. Fenbendazole and pyrantel showed a higher initial reduction in Parascaris egg counts when compared with the ivermectin-only-treated group, but this difference lessened over time. The use of the combination treatment showed the best results for controlling both parasites, indicating that a combination of anthelmintics may be necessary to control parasites on some equine farms.
