        Vitamin K1 (VK1) has been widely used as a coumarin antagonist and for the treatment of hemorrhagic disease in veterinary practice. However, the potential mechanism of adverse reaction after VK1 injection has been not fully elucidated. In this study, two cases of anaphylactic reactions after subcutaneous VK1 injection were presented, and then an experimental study was performed to further characterize the anaphylactic reactions. Two dogs developed anaphylactic reactions after subcutaneous VK1 injections and were promptly treated with antihistamines and glucocorticoids, after which abnormal signs related to anaphylaxis disappeared. Subsequently, a study was undertaken to ascertain the nature of the adverse reactions to subcutaneous VK1 injection. Six healthy laboratory beagle dogs received subcutaneous VK1 administrations once daily for eight days. They were monitored for clinical signs after each injection, and blood samples were collected for the measurement of plasma histamine and immunoglobulin E concentrations using enzyme-linked immunosorbent assay. All six dogs showed mild angioedema after the VK1 injections. The dogs also displayed clinical signs including sneezing, coughing, skin reddening, excess salivation, pawing the ground, and somnolence on days 4, 6, and 8. Plasma histamine and immunoglobulin E concentrations were significantly increased by the repeated injections. In summary, this study describes anaphylactic reactions resulting from subcutaneous VK1 administration in dogs. Clinicians should be aware that the repeated subcutaneous injection of VK1 can trigger an anaphylactic reaction in dogs.

        A one-year-old, intact female, Maltese dog was presented with a history of anorexia and regurgitation. Thoracic radiographs and ultrasonography scans suggested an abnormal mass in the cranial mediastinal region, and computed tomography confirmed the origin of this mass. Ultrasound-guided fine needle aspiration cytology showed the presence of intermediate to large lymphoid cells showing mitotic figures. B-cell lymphoma was confirmed by the result of a polymerase chain reaction assay for antigen receptor rearrangement, therefore the patient was diagnosed with primary mediastinal large B-cell lymphoma (PMBL). The patient underwent L-CHOP (L-asparaginase, cyclophosphamide, doxorubicin, vincristine, prednisolone)-based chemotherapy, and showed complete tumoral remission from the beginning of chemotherapy. Seventytwo weeks after the completion of chemotherapy, the patient is still alive without any evidence of metastasis or relapse. A standardized treatment protocol has yet to be established for primary mediastinal lymphoma in dogs. This case report describes the complete remission of PMBL by an L-CHOP-based chemotherapy protocol in a young Maltese. Clinicians should consider that L-CHOP based chemotherapy may be useful against PMBL in dogs.

        Skin barrier function can be assessed non-invasively, including by transepidermal water loss (TEWL), skin hydration, and sebum level. The aim of this study was to evaluate day-to-day variation in measurements of TEWL, skin hydration, and sebum level at various anatomic sites and the relationship between these parameters in normal dogs. Measurements were repeated five times on two separate days in five clinically normal Beagle dogs at seven anatomic sites, i.e., the left and right pinnae, left and right axillae, left and right groin areas, and ventrum. Coefficient of variation was used to show the variation in measurements. Correlations between each of the measurements were analyzed to determine the contribution of skin hydration and sebum level to TEWL. There was no variation in the measurements obtained according to time or anatomic site (P>.0.05). The coefficient of variation was highest for sebum level (209.0 ± 81.8%) followed in descending order by skin hydration (62.7 ± 34.5%) and TEWL (41.1 ± 6.9%). Of the seven anatomic sites sampled, the left and right pinnae showed the lowest variation in repeated measurements for TEWL (39.2%), skin hydration (29.6%), and sebum level (75.5%). There was no significant relationship between the results for each measurement (P>.0.05). Because of its relatively low variation on repeated measurement, TEWL might be the most useful way of evaluating skin condition in dogs.

        This report describes the different responses to dapsone treatment in two cases of sterile nodular panniculitis (SNP). Two dogs were presented with ulcerative skin lesions, painful and erythematous papules, and nodules. History and physical examination revealed systemic signs such as pyrexia, lethargy, depression, and anorexia, in addition to ulcerated and ruptured nodules on the skin. The dermatological diagnostics included clear taping, trichogram, skin scraping, impression smears, fungal and bacterial cultures, and histopathology and special stainings of multiple punch biopsies obtained from the skin lesions. Based on the clinical and histopathologic findings, the absence of microbiological infection, and the positive response to immunosuppressive therapy, both the dogs were diagnosed with SNP. Although both dogs had been treated with various immunosuppressive drugs including prednisolone, cyclosporine, azathioprine, and triamcinolone, therapy was switched to dapsone due to recurrent dermatological signs and presumed steroidinduced hepatotoxicity. The clinical responses to dapsone were opposite in the two cases. In the first case, combination therapy with prednisolone and cyclosporine was effective in attenuating ulcerative lesions, while dapsone alone did not control the clinical signs. In contrast, in the second case, the therapeutic response to the common immunomodulatory drugs such as prednisolone, triamcinolone, and azathioprine was inadequate. Interestingly, dapsone alone was effective in controlling the clinical signs without causing undue side effects. Although the usefulness of dapsone for the treatment of canine SNP is unknown, it may be considered in mild to moderate cases of SNP when the use of steroids is not recommended due to its low efficacy or side effects.

        The intradermal test (IDT) has been developed for confirming diagnosis of canine atopic dermatitis (CAD). Prior to performing IDT, rapid immunoassay (Allercept E-screen 2nd generation; ES2G) can detect allergen-specific immunoglobulin E (IgE) antibodies in canine serum. The objective of this study was to evaluate agreement between IDT and immunoassay in diagnosis of CAD in domestic atopic dogs. Forty dogs were diagnosed with CAD in accordance with Favrot’s criteria. Intradermal testing was performed using 39 selected allergens. ES2G detected IgE antibodies specific for three allergen groups, including indoor allergens, grasses and weeds, and trees. Among 19 dogs diagnosed by IDT, the highest positivity was observed in house dust mites, followed by molds, epidermis and inhalants, house dust, and weeds. A total of 28 atopic dogs were evaluated by rapid ES2G immunoassay. Indoor allergens showed the strongest positive reaction, followed by grasses/weeds and trees. IDT and ES2G were performed concurrently in 17 dogs. The results of ES2G showed slight agreement with those of IDT. Level of agreement was highest for indoor allergens, which showed a predictive positive value of 100% in ES2G. These results indicate that a rapid immunoassay may be valuable for predicting the results of IDT in atopic dogs sensitized to indoor allergens.

        Pruritus is one of the most important symptoms of allergic inflammatory skin disease. Conjugated linoleic acid (CLA) has been reported to have preventive effects against allergic inflammation. The objective of this study was to determine whether or not oral administration of CLA suppresses pruritus induced by compound 48/80 (composed of N-methyl-p-methoxy phenethylamine with formaldehyde) in mice, and if so, whether or not this effect is associated with serum histamine and prostaglandin (PG) E2 levels. Liquid CLA mixture (36.25% 9c-11t CLA, 36.95% 10t-12c CLA, 1.12% 9c-11c, and 1.94% t9-t11 CLA) was emulsified in 0.5% carboxymethyl cellulose (CMC) sodium salt and orally administered to mice at doses of 200 mg/kg once per day for 3 days. Similarly, disodium chromoglycate (DSCG), an antipruritic substance, was administered orally at the same concentrations as the negative control. Compound 48/80, a pruritus-inducing reagent, was subcutaneously injected 30 minutes after final administration of CLA. Scratching behavior of mice was counted just after compound 48/80 injection. Serum histamine and PGE2 concentrations were evaluated individually. Mice administered with CLA showed reduced frequency of scratching behavior compared to those without CLA. Antipruritic activities in CLA-treated and DSCG-treated groups were 48.5% and 26.8%, respectively. CLA and DSCG also diminished serum concentrations of histamine and PGE2 compared to compound 48/80 alone, respectively. This result suggests that dietary CLA has an antipruritic effect by down-regulating serum histamine and PGE2 levels for relief of compound 48/80-induced scratching behavior in mice, which will be useful in allergic pruritus as a preventive medicine.

        A-7-month-old, intact male Shih-Tzu dog was referred with facial dermatitis and stifle pain with 7 days duration. Erythema, hemorrhage, and crusted nodular lesions of the face, swollen eyelids, and otitis externa were observed. A painful response was noted on palpation of the right stifle joint. Impression smears and skin biopsies revealed pyogranulomatous inflammation consistent with canine juvenile cellulitis (CJC). Skin lesions and pain were greatly improved following immunosuppressive corticosteroid therapy. This report firstly describes clinical and histopatho- logical findings as well as treatment responses of CJC in a 7-month-old, domestic dog.

        A 10-year-old intact female Cocker Spaniel weighing 15.3 kg presented with dysbasia. The dog had hyperglycemia and glucosuria at presentation. Neurological examination and magnetic resonance imaging on the following day indicated the onset of cervical disk disease. Four days later, the patient returned due to sudden vomiting and anorexia with severe dehydration. Abnormal laboratory findings included severe hyperglycemia with ketonuria. Plasma progesterone concentration was very high at presentation. She was hospitalized for critical care, and insulin administration with fluid therapy was initiated. Mean blood glucose concentration showed a gradual decline, and hyperglycemia with glucosuria disappeared four days after initiation of insulin therapy. This case demonstrated that high plasma progesterone concentration during diestrus can contribute to development of diabetes mellitus in intact female dogs.
