Mohs paste is used for the management of malignant skin tumors, with bleeding, exudate and malodor. Mohs paste is usually directly applied to skin lesions but is difficult to use because of its high viscosity and tackiness. For use with humans, Mohs gauze method, which is modified Mohs paste method that spread past on gauze, was invented for ease of use on skin lesions. In this study, we used Mohs gauze method to treat an unresectable ruptured mammary gland tumor in a miniature dachshund. We succeeded in drastically reducing the tumor volume. Thus, this method can be used for many shapes of tumor in various animal cases.
Lichenoid keratosis was found in three toy poodles. All cases were juvenile onset and no apparent sex predisposition was found. Skin lesions were characterized by demarcated keratinizing plaques and papules at mainly the medial pinnae. Histopathology revealed acanthosis with hyperkeratosis, as well as lymphocytes and plasma cells infiltration. Topical glucocorticoids were relatively effective at managing the skin lesions. Further cases will be necessary to gain an understanding of canine inflammatory keratosis, and comparative studies with human inflammatory keratosis are warranted.
The present study determined the prevalence of dermatophytes in 101 young cats with and without skin lesions, in eight pet shops using a culture method. Dermatophytes were detected in four cats (4.0%), suggesting that the prevalence of dermatophytes is not high among pet shop young cats in Japan. Only one of the four cats with dermatophytes showed a cutaneous lesion. All of the isolated dermatophytes were identified as Microsporum canis by direct sequencing of amplicons obtained from PCR targeting the region including ITS-1 of the rRNA gene.
The aim of this study was to re-evaluate the breakpoint of the cefovecin (CFV) disk diffusion test for predicting oxacillin (MPIPC)-resistance in Staphylococcus pseudintermedius isolated from dogs with pyoderma or healthy dogs. There was a significant positive correlation between CFV and the MPIPC disk diffusion zone diameters. The receiver operating characteristic curve revealed that the best CFV breakpoint for predicting MPIPC resistance was ≤25 mm. The concordance rate of the susceptibility and resistance to CFV and MPIPC in S. pseudintermedius was 96.9%. In summary, the CFV disk diffusion test with the newly estimated breakpoint is valid for the prediction of MPIPC-resistance in S. pseudintermedius.
