Canine Vogt-Koyanagi-Harada-like Syndrome in Two Siberian Husky Dogs

Abstract— A syndrome of uveitis, associated with depigmentation and erosion of areas of skin and mucous membrane on the head and, in one dog, on the scrotum, was observed by the authors in two male Siberian Huskies. These clinical signs are similar to the Vogt-Koyanagi-Harada syndrome in man. Histological examination of the affected skin revealed a lichenoid dermatitis of the upper dermis. Intensive topical therapy with mydriatic and cycloplegic drugs and corticosteroids coupled with systemic prednisolone and azathioprine were used to control the disease. Both subjects were monitored for 10 months and retained useful vision. The skin and oral lesions resolved. Résumé— Un syndrome d'uvéite idiopathique, non traumatique, associée à une dépigmentation et une érosion de zones cutanée et muqueuse sur la tête et, chez un chien, sur le scrotum, a été observé par les auteurs sur deux mâles Siberian Huskies. Ces signes cliniques évoquent le syndrome de Vogt—Koyanagi—Harada de l'homme. Un examen histologique de la peau atteinte a montré l'existence d'une dermatite lichénoide du derme superficiel. Un traitement topique intensif par des médicaments mydriatiques et cyclopégiques, ausociéà l'administration systémique de prednisolone et d'azathioprine a été utilisé pour controler la maladie. Les 2 sujets ont été observés pendant 10 mois et ont retrouvé une vision utile. Les lésions cutanées et orales ont guéri. Zusammenfassung— Bei zwei Husky-Rüden wurden von dem Autoren ein Krankheitssyndrom aus idiopathischer, nicht-traumatisch bedingter Uveitis, Depigmentierung einzelner Haut- und Schleimhautbezirke am Kopf und—bei einem Hund—am Skrotum festgestellt. Diese Symptome ähneln dem Vogt-Koyanagi-Harada-Syndrom beim Menschen. Bei der histologischen Untersuchung von Biopsien der erkrankten Hautbezirke wurde eine lichénoide Dermatitis der oberen Dermisschichten diagnostiziert. Durch eine intensive örtliche Behandlung mit Mydriatica, Cycloplegica und Corticosteroiden in Kombination mit systemischer Prednisolon- und Azathioptringabe konnte die Erkrankung unter Kontrolle gehalten werden. Beide Patienten wurden 10 Monate überwacht und sahen zufriedenstellend aus. Die Veränderungen an Haut und Mundhöhle bildeten sich zurück. Resumen Los autores describen un síndrome de uveitis no traúmatica idiopática asociada a una despigmentación y erosión de áreas de la piel y de las membranas cutáneas de la cabeza, en un perro y del escroto en otro perro. Ambos animales pertenecían a la raza Siberian Husky. Estos signos clínicos se asemejan en los descritos en la síndrome de Vogt-Koyanagi-Harada de las personas. El examen histológico mostró la presencia de un infiltrado inflamatorio liquenoide en la dermis superficial. Para el tratamiento a la enfermedad se aplicaron corticosteroides y fármacos midriáticos y ciclopéjicos de forma tópica y prednisona de forma sistémica. Ambos animales fueron controlados durante diez meses y mantuvieron la visión. Las lesiones orales y cutáneas se resolvieron por completo.     

A RETROSPECTIVE ANALYSIS OF 140 DOGS WITH ORAL MELANOMA TREATED WITH EXTERNAL BEAM RADIATION

Despite the early notion that canine oral malignant melanoma is radioresistant, recent data suggest that external beam radiotherapy is effective in local tumor control. However, optimal fractionation schedules have not been established. The high rate of regional and distant metastasis is another problem that has hindered long-term control. The role of chemotherapy in the management of canine oral melanoma has also not been determined. In this study, data from 140 dogs irradiated at North Carolina State University were evaluated with the following objectives: (1) to compare the efficacy of three radiation therapy protocols (36 Gy, 9 Gy x 4 fractions; 30 Gy, 10 Gy x 3 fractions; or >45 Gy, 2-4 Gy x 12-19 fractions) for the treatment of dogs with oral malignant melanoma, (2) to identify any host or tumor factors influencing prognosis, and (3) to determine the impact of systemic chemotherapy on treatment outcome. Information regarding response to therapy, disease progression, and survival were determined from the medical records or from information obtained by telephone or mail survey. Relationships between host, tumor, and treatment variables and outcome measures (response, time to first event, and survival) were evaluated using Fisher's exact test (response) and the Cox regression model (time to first event and survival). The median time to first event for the 140 dogs was 5.0 months (95% C.I., 4-6 months) and the median survival was 7.0 months (95% C.I., 6-9 months). In the univariate analysis, the following variables were associated with increased time to first event and survival: (1) rostral tumor sublocation; (2) lack of bone lysis observed on skull imaging, and (3) microscopic tumor burden. In a multivariate analysis of 111 dogs with complete data for these variables, tumor sublocation, bone lysis, and tumor volume were identified as joint predictors of time to first event (p < .001, p < .001, and p = .04, respectively) and survival (p < .001, p < .001, and p = .05, respectively). There were no differences in response, time to first event and survival between the three radiation therapy protocols used. Systemic chemotherapy had no impact on the development of metastatic disease, time to first event, or survival, although the dosages used in this study were suboptimal. External beam radiation therapy is effective in local disease control of canine oral malignant melanoma; however, the optimal fractionation scheme has yet to be determined. The high metastatic rate observed with this disease and the inefficacy of systemic chemotherapy indicate that further investigation into novel therapies is warranted.

Effect of Weather and Soil Conditions on Yield Components and Bread-Making Quality of Winter Wheat (Triticum aestivum L.) and Winter Triticale (Triticosecale Wittm.) Varieties in North-East Germany

The reduced nutrient and water availability of the sorption‐weak silty sand soil in Thyrow when compared with the loamy sand soil in Berge enhanced the negative effects of unfavourable weather conditions. Winter wheat reacted to weather conditions and soil quality substantially more sensitively than winter triticale, so that the cultivation of wheat on very light sandy soil is combined with a higher risk. Reduced yields resulting from site differences are, for both cereals, mainly a result of reduced ear densities. Low grain yields as in the dry year 2003 led to high crude protein contents, this being more pronounced for winter wheat than for triticale and on the poor silty sand soil in Thyrow to a greater degree than on the loamy sand soil in Berge. For the starch content the contrary holds true. Grain yields were, to a greater extent, decisive for the protein and starch yields than the content values. For both cereals, the sedimentation value, the wet gluten value, the gluten index and the falling number resulted in principally higher values in the dry year 2003 and on the loamy sand soil when compared with the wet year 2004 and the silty sand soil. Only the wet gluten content was not clearly influenced by soil quality. All parameters describing bread‐making quality are clearly lower for winter triticale than for winter wheat. Especially, the falling number was not satisfactory, so that the tested triticale varieties seem only to be suitable for bread‐making by mixing with wheat flour. The internal grain quality of winter wheat varieties is extensively genetically determined. Weather and soil‐induced variations in the quality parameters were, with only few exceptions, greater for winter wheat than for triticale.     

Vascular-targeted photodynamic therapy (VTP) of a canine-transmissible venereal tumour in a murine model with Pd-bacteriopheophorbide (WST09)

Treatment of canine‐transmissible venereal tumour (CTVT) with local vascular‐targeted photodynamic therapy (VTP) using Pd‐bacteriopheophorbide (WST09) as a drug is suggested as an alternative to conventional chemotherapy. Male CD1 nude mice were subcutaneously grafted with the xenograft‐transmissible canine venereal tumour (XTVT). The VTP protocol delivered once consisted of intravenous administration of WST09 (10 mg kg^?1) followed by immediate local illumination with a diode laser (763 nm). Controls included animals treated with light or WST09 alone. Macroscopic and microscopic evaluations of tumour response were conducted 10, 24 and 48 h after treatment. Upon VTP, tumours underwent necrosis that lasted 8–10 days and exhibited complete healing by 25–35 days, reaching an overall long‐term cure rate (83%) by 90 days after treatment. This study suggests that VTP with WST09 can efficiently treat CTVT in a single session, as compared with 4–6 sessions of chemotherapy and thus may be feasible for common veterinary practice, particularly under ambulatory conditions.
