This study evaluated PYM00217, a proprietary blend of plant extracts, in the management of canine atopic dermatitis (AD). One hundred and twenty dogs were diagnosed with perennial AD on the basis of history, clinical signs, a positive test for perennial allergens and elimination of other dermatoses. Exclusion criteria included antimicrobials within 7 days, antihistamines within 14 days, oral/topical glucocorticoids or ciclosporin within 28 days, and parenteral glucocorticoids, essential fatty acids or immunotherapy within 56 days. Flea control, shampoos and ear cleaners were permitted. Dogs with a minimum canine atopic dermatitis extent and severity index (CADESI) of 25 were randomly allocated to receive PYM00217 (100, 200 or 400 mg kg-1 day-1) or placebo for 12 weeks. The mean reductions in CADESI (intention-to-treat population) were 3.9% (placebo; n=29), 4.4% (100 mg kg-1 day-1; n=30), 23.4% (200 mg kg-1 day-1; n=29) and 8.5% (400 mg kg-1 day-1; n=29). The reduction in the 200 mg kg-1 day-1 group was significant (P<0.01). For dogs with a baseline CADESI>or=50, the mean changes were +10.6% (placebo; n=12), +0.6% (100 mg kg-1 day-1; n=14), -29.3% (200 mg kg-1 day-1; n=14) and -3.4% (400 mg kg-1 day-1; n=15). The 200 mg kg-1 day-1 dose was significantly more effective than placebo (P=0.038). No serious adverse effects were reported. Minor adverse effects seen in 10% (placebo and 100 mg kg-1 day-1), 24% (200 mg kg-1 day-1) and 42% (400 mg kg-1 day-1) of cases were mainly minor gastrointestinal disorders and only five cases required cessation of dosing. Two dogs (one in each of the 100 mg kg-1 day-1 and 200 mg kg-1 day-1 groups) refused to eat the medicated food. In conclusion, PYM00217 at 200 mg kg-1 appears to be an effective, palatable and well-tolerated treatment for canine AD. 相似文献

The authors report 10 cases of localised sarcoptic mange in dogs. In each case, lesions were localised to one precise area of the skin. Pruritus was present in nine cases and absent in one. Affected areas were the feet (one case), the face and/or the pinnae (six cases), the abdominal skin (one case), the flank (one case) and the lumbar area (one case). The types of lesions were erythema, papules, lichenification, scales, crusts and alopecia. Parasites were found in all cases except one, in which anti-immunoglobulin G Sarcoptes serology was positive. The acaricidal treatments given were lindane, ivermectin or selamectin and were all successful. 相似文献

Scleroderma is a rare chronic disease of connective tissues, involving the skin and/or internal organs in humans, and rarely described in the dog. A case is reported of localised scleroderma in a cat which presented with two well delineated alopecic, sclerotic, raised and shiny lesions localised on the trunk. Diagnosis was made by histopathological examination of skin biopsies which showed the replacement of all dermal components by dense thick collagen bundles. No therapy was instituted and a spontaneous recovery occurred three months later. Clinical and histopathological aspects of this feline dermatosis are compared with human and canine morphea. 相似文献

The authors make recommendations for the optimal use of topical glucocorticoids in routine practice based on their experience in canine dermatology and evidence from the literature. The rationale behind the use of topical glucocorticoids is reminded, as are the main factors to consider in the selection of the appropriate product from current therapeutic armamentarium, taking into account notably the anti-inflammatory power and side effects of glucocorticoid compounds, their percutenous penetration and absorption, as well as available veterinary presentations. The specific circumstances and instructions for use of topical glucocorticoids are developed in each of their main indications (atopic dermatitis, flea allergy dermatitis, pyotraumatic dermatitis, contact dermatitis, auto-immune dermatitis, perianal fistulas), as are reminded the limits to their use and potential side effects, underlining the need for proper education of the owner and good therapeutic monitoring of the patient.Download : Download Acrobat PDF file (17MB)English Version.

Histological lesions and the presence of Leishmania spp. amastigotes in claw tissues were investigated in 40 dogs with leishmaniosis, with (16/40--group A) or without (24/40--group B) generalized onychogryphosis. Following euthanasia, the entire third phalanx with intact claw was amputated, formalin fixed, decalcified in a formic acid solution, embedded in paraffin, sectioned longitudinally and stained with haematoxylin and eosin, and acid orcein-Giemsa. Nested polymerase chain reaction (PCR) was used for the detection of Leishmania amastigotes. Lichenoid mononuclear infiltration (all dogs in group A, 21 of 24 dogs in group B), basal keratinocyte vacuolation (nine of 16 dogs in group A, 15 of 24 dogs in group B) and dermoepidermal clefting (13 of 16 dogs in group A, 18 of 24 dogs in group B) were the most prominent histopathological findings. There was no difference in the frequency and severity of these lesions between the two groups. Leishmania amastigotes could not be visualized in the dermis of any of the H&E sections, but their presence was demonstrated by nested PCR in three of 16 dogs in group A and two of 24 dogs in group B. However, the frequency of positive nested PCRs was not significantly different between the two groups. In conclusion, claw histopathology in symptomatic dogs with leishmaniosis, either with or without onychogryphosis is mainly characterized by mononuclear lichenoid dermatitis with or without interface dermatitis and dermoepidermal clefting, and is not accompanied by substantial local parasitism. 相似文献

Enzootic dermatophytosis in a shelter with approximately 140 cats was treated according to a protocol combining identification, isolation and treatment of subclinical carrier and affected animals in accordance with a three‐area system: healthy animals (no lesions and negative cultures), subclinical carrier animals (no lesions but with positive cultures) and clinically affected animals (lesions and positive cultures). The cats were examined and inspected under a Wood’s lamp and had samples taken for fungal culture every 2 weeks. Thirty‐three per cent of the cats had a positive fungal culture at the start of the study. Clinically affected animals and carriers were treated with a 0.2% enilconazole lotion (Imaverol®) twice a week and given itraconazole (Itrafungol®) 5 mg/kg SID orally every other week. The environment was treated once a day with a 1% bleach solution and once a week with a 0.6% enilconazole (Clinafarm®) solution. Treated animals were considered cured after two consecutive negative fungal cultures. All cats were cured within 56 days. Prophylactic measures against dermatophytosis were implemented for new arrivals consisting of individual quarantine and the systematic taking of fungal cultures. No relapses were observed based on the fungal cultures taken from the animals and the environment over the first 10 months. 相似文献
