Abstract

Objective—To determine effects of management, feeding, and treatment on clinical and biochemical variables in cows with displaced abomasum (DA).

Animals—374 cows that received 470 treatments for DA.

Procedure—Blood and milk samples were obtained from 139 affected cows for analysis; for all cows, clinical data, management, feeding, and treatments were evaluated.

Results—Multiparous cows were more predisposed to DA than primiparous cows were, and Swedish Friesians were more predisposed than Swedish Red and Whites were. Eighty percent of cows had leftsided DA, and 20% had right-sided DA. In > 50% of affected cows, clinical signs appeared just before calving to 2 weeks after calving. Incidence of twin calves and periparturient diseases was significantly higher in affected cows than in the overall Swedish cow population. Content of neutral detergent fiber in the silage was low in herds with DA. Feeding a total mixed ration was a risk factor for DA. Treatment by surgical methods gave a significantly higher recovery rate than nonsurgical methods.

Conclusion and Clinical Relevance—Displaced abomasum is a periparturient nutritional disease. Feeding roughage with low neutral detergent content is a more important causative factor than the amount of concentrates fed at the time of calving. The basic principle for prevention of DA is to maintain good ruminal filling before and at calving. The amount of high-quality roughage fed before and at calving should be kept to a minimum. By changing routines for periparturient feeding, it should be possible to reduce the incidence of DA. (Am J Vet Res 2002;63:137–142)

Abstract

OBJECTIVE

To describe the effect of a mesotherapy protocol in dogs with osteoarthritis.

ANIMALS

30 dogs.

PROCEDURES

Dogs were randomly assigned to a control (CG; n = 10) or a mesotherapy group (MG; 20). CG received meloxicam for 70 days. MG was treated with a combination of lidocaine, piroxicam, and thiocolchicoside, injected in intradermal points. Seven treatment sessions were conducted. Response to treatment was measured with different instruments: the Canine Brief Pain Inventory (divided into Pain Interference Score [PIS] and Pain Severity Score [PSS]), Liverpool Osteoarthritis in Dogs (LOAD), and Canine Orthopedic Index (COI; divided into function, gait, stiffness, and quality of life), at time 0 (T0), +15 days, +30 days, +60 days, and +90 days after T0. At each time point, the results of the 2 groups with each instrument were analyzed with the Wilcoxon signed ranks test, P < .05. Kaplan-Meier estimators were compared with the Breslow test.

RESULTS

Dogs had a mean age of 6.9 ± 2.7 years and a body weight of 31.0 ± 6.4 kg. Hip osteoarthritis was classified as mild (n = 9), moderate (17), or severe (4). No differences were found at T0. Better results were observed in MG at +15 days (P < .01 for PSS and PIS, P = .03 for function), +30 days (P = .01 for PIS and LOAD, P = .03 for PSS, and P = .04 for function, gait, and COI), +60 days (P < .01 for PSS and PIS, P = .01 for LOAD, and P = .02 for function), and +90 days (P = .01 for PSS and PIS, P = .03 for LOAD, and P = .04 for function). Kaplan-Meier estimators showed MG had longer periods with better results than CG in various scores.

CLINICAL RELEVANCE

This mesotherapy protocol reduced pain scores and other clinical metrology instrument scores lasting for longer periods.

Abstract

OBJECTIVE

To perform the initial psychometric evaluation of the Portuguese version of the Canine Brief Pain Inventory (CBPI).

ANIMALS

A total of 100 dogs, 50 with bilateral hip osteoarthritis and 50 unaffected dogs.

PROCEDURES

The 2 groups of dogs were assessed using the CBPI. The English version of the CBPI (divided into a pain severity score and a pain interference score) was translated into Portuguese, and a copy of the translated version was completed by native Portuguese speakers’ canine handlers. The results from the 2 groups were compared, and psychometric properties were evaluated. Construct validity was evaluated by assessing differences between animals with osteoarthritis and unaffected animals with the Mann-Whitney test. Further evaluation was performed with the Kaiser-Meyer-Olin measure of sampling adequacy, Eigenvalue, and scree-plot analysis. Internal consistency was tested with Cronbach α.

RESULTS

A significant difference was observed between dogs with osteoarthritis and unaffected dogs in pain severity and pain interference scores (P < .01 for both), one indication of construct validity. Cronbach α was 0.99, and a high interitem correlation was observed, showing strong internal consistency. One factor accounted for 92.3% of the total variance.

CLINICAL RELEVANCE

We presented the initial validation of the Portuguese version of the CBPI and its validity in the Portuguese language. It is an essential step in providing a valid tool for clinicians to assess pain in dogs with osteoarthritis. Further studies are required to determine if the present results can be replicated across samples with different characteristics and evaluate response to treatment.
