Investigations of the symptomatology and the significance of immediate skin test reactivity in canine atopic dermatitis.

Immediate skin test reactivity was determined with skin threshold concentrations of different allergen solutions in 208 dogs suspected of atopic dermatitis. Thirty-eight of the dogs (18.3 per cent) exhibited no reaction. Multisensitivity occurred in 59.1 per cent. House dust (39.4 per cent), human dandruff (39.9 per cent), dog dandruff (25.0 per cent), cat dandruff (29.8 per cent) and grasses (21.2 per cent) caused most of the positive reactions. The number of immediate skin reactions per dog was increased in those dogs that had had clinical signs for two to three years, as compared to dogs having had clinical signs for five or more years. Involvement of the extensor aspect of the carpal joint (41.2 per cent) and the flexor surface of the tarsal joint (30.6 per cent) was noticed only in dogs with positive immediate skin test reactivity. Together with the frequent occurrence of lichenification (84.1 per cent) this distribution pattern in dogs seems to mimic the signs of atopic dermatitis in man more closely than has been described previously.

Evaluation of the intradermal allergy test in normal dogs.

In 45 normal dogs, serial dilutions of different allergens were injected intradermally to determine the skin threshold concentrations. For housedust, housedust mite (Dermatophagoides pteronyssinus) and human dandruff extracts these were found to be the same in the dog as in man, while those for animal dandruffs, pollens and fungi were 10 times higher in the dog. The term 'histamine reactive value' (RH) is introduced for the dog. The mean (+/-SD) was found to be 49.0 +/- 2.5 in normal dogs, using histamine diphosphate solutions of 0.01, 0.1 and 1 per cent.

[Bacterial skin infections in the dog (author's transl)].

The most common bacterial skin conditions in dogs are reviewed in the present paper. An introductory part on the pathogenesis of pyoderma and some universal morphological dermatological concepts is followed by a systematic study of superficial and deep forms of pyoderma. In addition to the bacterial diagnosis, the results of bacteriological examination of fifty-three dogs with pyoderma submitted to the University Clinic of small animal medicine are reported. Moreover, a guide to the institution of adequate therapy is suggested.

Cryosurgery of eosinophilic ulcers in cats.

The use of cryosurgery in treatment of eosinophilic granuloma in cats is described. Satisfactory results were obtained in 14 of 19 cats and 4 of the 5 cats which did not respond favorably, had multiple lesions. The simplicity of the technique and the rapidity of healing make cryosurgery a useful alternative to previous methods of treatment.

[An atypical form of Aujezky's disease after vaccination (author's transl].

Four atypical case of Aujezky's disease in dogs are described. Two weeks before the outbreak of the disease, the dogs had been vaccinated with a live tissue culture vaccin, based on the Bartha strain. By culturevirus (cytopathogenic effect) the Bartha vaccin was identified and a vaccination reaction was proved. Vaccination with this must be discouraged.

The Hamilton Depression Rating Scale (HDRS); changes in scores as a function of training and version used.

The co-existence of different versions of the Hamilton Depression Rating Scale (HDRS) may introduce a source of error in depression research. In a training procedure, based on 16 videotapes, over 900 scores were used to investigate differences between two prominent versions. The HDRS published by Bech et al. in 1986 produced significantly lower total scores than the original HDRS presented by Hamilton in 1960. Previous experience of the raters, both in psychiatry and in the use of the scale, increased the scores in a nonsignificant way. During the training raters' scores increased significantly. These effects were small, one point each in the total scores, but they were consistent throughout our material. In depression research, training procedures and the exact version of the scales used should be specified.
