Herd-Level Monitoring and Prevention of Displaced Abomasum in Dairy Cattle.

Displaced abomasum (DA) is a postpartum disease that causes significant economic losses in the dairy industry. Abomasal atony and excessive production of gas have been reported as prerequisites for the development of DA. The exact cause of DA is unknown, yet infectious and metabolic disease, diet composition and physical form, cow comfort, and management of dairy cows during the transition period have been associated with the occurrence of this disorder. This review article discusses different factors that lead to the development of DA and strategies for monitoring DA and its comorbidities at the herd level.

Treatment of lateral epicondylitis.

Lateral epicondylitis is a common overuse syndrome of the extensor tendons of the forearm. It is sometimes called tennis elbow, although it can occur with many activities. The condition affects men and women equally and is more common in persons 40 years or older. Despite the prevalence of lateral epicondylitis and the numerous treatment strategies available, relatively few high-quality clinical trials support many of these treatment options; watchful waiting is a reasonable option. Topical nonsteroidal anti-inflammatory drugs, corticosteroid injections, ultrasonography, and iontophoresis with nonsteroidal anti-inflammatory drugs appear to provide short-term benefits. Use of an inelastic, nonarticular, proximal forearm strap (tennis elbow brace) may improve function during daily activities. Progressive resistance exercises may confer modest intermediate-term results. Evidence is mixed on oral nonsteroidal antiinflammatory drugs, mobilization, and acupuncture. Patients with refractory symptoms may benefit from surgical intervention. Extracorporeal shock wave therapy, laser treatment, and electromagnetic field therapy do not appear to be effective.
