RESUMEN
Chronic Superficial Keratitis (CSK) is an autoimmune mediated inflammation of the cornea, that is usually bilateral but often with nonsymmetrical manifestation. The aim of this study was to determine the occurrence and appearance of clinical symptoms of CSK in German Shepherd dogs in Poland and Slovakia. CSK was diagnosed in 308 German Shepherds for a period of 11 years (from 1999 to 2010). The highest incidence of the CSK (p < 0.001) in Slovakia and in Poland was in dogs between the ages of 5-8 years. This study found similarity in gender ratio of affected patients with CSK in two neighboring countries. This disease occurs most often in males, with almost identical frequency in both countries, Slovakia 65.63% and Poland 61.32%, respectively. The incidence of depigmentation and thickening of the external surface of the third eyelid together with CSK was observed in 69.19% of dogs in Poland and in 63.15% of dogs in Slovakia. CSK is often recognized in advanced stage-affected areas with inflammatory process by CSK, obtained frequently from 2 to 3 quadrants.

Canine hip dysplasia (CHD) is a locomotive-system disease in dogs, which in many countries is the target of screening programs aimed at reducing the prevalence of CHD among descendants of predisposed dog breeds. Despite the efforts to apply genetic testing or ultrasound diagnostics in diagnosing CHD (as is common in human medicine), the main diagnostic process in veterinary medicine is by radiographic examination. The main two parameters which are used in diagnosing HD are the Norberg angle (NA) and the position of femoral head centre to the dorsal acetabular edge (FHC/DAE). We examined the relationship between these two parameters in the process of the determination of CHD degree by evaluating 225 randomly selected radiographs which were made during the period from 1993 to 2008. The aim of our study was to examine the validity of these two parameters in CHD classification as used in three different classification programs. Using Pearson's correlation coefficient, the value of which was 0.85 (p <0.05), we observed a positive correlation. Comparing the three scoring systems for CHD evaluation, we found that the final degree of CHD was similar for 78% to 85% of cases using Flückiger's scoring system versus a modified scoring system of 5 parameters without FHC/DAE. Results were significant.
