Intra- and Inter-observer Variability of Computed Tomographic Measurements of the Prostate Gland in Neutered Dogs.

The purpose of this study was to evaluate the intra- and inter-observer variability of computed tomographic measurements of linear prostate dimensions in neutered dogs without signs of prostatic disease, to determine potential associations between prostatic parameters and body weight or age and to provide reference ranges. Length, width and height of the prostate gland were measured in 62 neutered dogs with no signs of prostatic disease by three observers with different levels of training. Statistically significant positive associations were found between all prostatic parameters and body weight and between all prostatic parameters and age at castration, but not with age.

Canine leptospirosis in Switzerland-A prospective cross-sectional study examining seroprevalence, risk factors and urinary shedding of pathogenic leptospires.

Leptospirosis is an important worldwide zoonosis. While human leptospirosis remains rare in Switzerland, the incidence of canine leptospirosis is unusually high compared to other European countries. The aims of this cross-sectional study were to determine the exposure of asymtomatic dogs to pathogenic Leptospira in Switzerland, to characterise risk factors associated with seropositivity and to determine the prevalence of urinary shedding.

Prognostic significance of Ki67 evaluated by flow cytometry in dogs with high-grade B-cell lymphoma.

Ki67 can discriminate between high- and low-grade canine lymphomas, but its prognostic role in specific subtypes of the neoplasm is unknown. We assessed the prognostic significance of Ki67% (percentage of Ki67-positive cells), evaluated by flow cytometry, in 40 dogs with high-grade B-cell lymphoma, treated with a modified Wisconsin-Madison protocol (UW-25). The following variables were investigated for association with lymphoma specific survival (LSS) and relapse free interval (RFI): Ki67%, breed, sex, age, stage, substage, complete remission (CR).

[Circulating immune complexes and bronchopulmonary cancers].

This study of circulating immune complexes was carried out using a C1q radio-labelled complement fixation test in 162 patients suffering from broncho-pulmonary disease. There were a similar number of positive results in primary cancer (44%) or secondary (53%) in tuberculosis (37%) or other pathologies (64%). With primary causes neither the histological type nor the stage of extension were associated with any particular frequency of positive tests.

[Epidemiology of Legionnaires' disease].

The authors discuss the epidemiological problems of legionnaire's disease. Although Legionella is known to proliferate in watery environments, the origin and extension of sporadic cases and the factors responsible for bacterial spread remain unclear. The problem of prevention has also to be resolved.

[Pulmonary silicosis (not including asbestosis and berylliosis].

The pleuro-pulmonary pathology of asbestos, top most of silicates, is today well known. Other silicates, talcum powder, clays, micas essentially, are exploited and commercialized. Their pathology is less well known and often contradictory because of the heterogeneity of the inhaled minerals.

[Posttraumatic real and false Mendelson's syndromes].

Six observations of post-traumatic acute respiratory insufficiency of alveolar origin are reported briefly. Three of them have been attributed to a Mendelson's syndrome. This authors showed that diagnosing these lung diseases by acid inhalation is particularly difficult in casualties.
