Background: Cold atmospheric plasma (CAP) is a new therapeutic tool used to treat various skin diseases in humans and animals., Objective: To evaluate the effect of CAP in the treatment of canine acute otitis externa (AOE)., Animals: Four client-owned golden retriever dogs with bilateral AOE., Methods and Materials: After cleaning with a commercial ear cleanser, right ears (STANDARD group) were treated with an antibiotic/antifungal/corticosteroid combination and left ears (CAP group) were treated with CAP every three days for a total of four treatments. Cytological score and otitis index score (OTIS)3 were recorded for each ear on Day (D)0, D10 and D15. At D10 and D15, owners and investigators recorded an overall assessment., Results: In both groups, OTIS3 and cytological score decreased over the study period. The overall assessment scale ranged from moderate to excellent in both groups., Conclusions and Clinical Relevance: Cold atmospheric plasma treatment showed equal therapeutic effect compared with a commercial topical anti-inflammatory and antimicrobial ear treatment., (© 2024 ESVD and ACVD.)

Background: Information on acute-phase protein (APP) concentrations in dogs with sarcoptic mange (SM) is scarce., Objective: To determine the effects of the clinical severity of disease and concomitant pyoderma on serum C-reactive protein (CRP), serum amyloid-A (SAA), haptoglobin (Hp) and ceruloplasmin (Cp) concentrations in dogs with SM., Animals: Forty client-owned dogs with SM (INF group) and 10 healthy control dogs (CON group)., Materials and Methods: The INF group was divided into three subgroups; Group 1 (mild/moderate), Group 2 (severe) and Group 3 (severe+pyoderma) according to the extent of skin lesions and the presence of concomitant pyoderma. Serum CRP, SAA, Hp and Cp concentrations of all study groups were measured., Results: Serum CRP (P < 0.001), SAA (P < 0.001) and Hp (P = 0.016) concentrations of the INF group were higher than the CON group, with no difference in terms of Cp. A statistical difference was measured between groups 2 and 1 in SAA only. C-reactive protein was found to be significantly higher in dogs with severe SM accompanied by pyoderma (Group 3) when compared with dogs with severe SM (Group 2). The area under the receiver-operating characteristic curves differentiating pyoderma among dogs with severe SM was 0.850 for CRP (P = 0.0001, cut-off value >61.3 mg/L with sensitivity 69.29% and specificity 90.91%)., Conclusions: The unique findings in this were that the SAA serum concentrations are related to the severity of SM and that serum CRP concentrations are effective in detecting the presence of pyoderma in dogs with severe SM., (© 2022 ESVD and ACVD.)

Six rabbits naturally infested with Psoroptes cuniculi were treated topically on the skin at the base of the neck with 0.5 mg kg(-1) of 0.5% pour-on eprinomectin for cattle, twice at 14-day intervals. Efficacy of the drug was based on the disappearance of clinical signs and the absence of live mites for a period of 6 weeks. Clinical improvement was seen within 3 days of the first application; however, complete recovery of clinical signs and elimination of mites in 5/6 rabbits did not occur until the end of the study. No adverse reactions attributable to eprinomectin treatment were observed during the observation period. Results of this trial indicated that eprinomectin was partially effective in the treatment of psoroptic mange in rabbits.

The efficacy of administering doramectin after moxidectin treatment, which has previously proved only partially effective, was evaluated in five Angora rabbits naturally infested with Sarcoptes scabiei mange. Evaluations included physical examination for clinical signs of sarcoptic mange and collection of skin scrapings for determination of mites. The rabbits first received two subcutaneous injections, 10 days apart, of moxidectin 1% injectable solution at a dosage of 0.2 mg kg(-1) of bodyweight. Although moxidectin treatment resulted in clinical improvement within 10 days post initial injection, on days 10 and 35 post initial treatment live mites were present in skin scrapings. Administration of doramectin 1% injectable solution using the same route and dosage and at similar intervals to moxidectin led to complete disappearance of signs of scabies and parasitological cure in all rabbits.
