[Paratuberculosis in cattle. Reflections on the interactions with Crohn disease in humans. A literature review]. / Paratuberkulose beim Rind, Heutiger Stand der Dinge. Uberlegungen zu einer Interaktion mit Morbus Crohn beim Menschen, Eine Literaturstudie.

Based on more than 30 literature references, the author tries to explain the phenomena of paratuberculosis in cattle. He gives a short description of the origin of the infection, the disease categories, the diagnostic problems and eradication. Also the human infection with the Mycobacterium known as Mycobacterium avium supspecies paratuberculosis (MAP)--a recognized pathogen in animals causing some or possibly all cases of Crohn's disease will be discussed. The conclusion is that until now no study gives evidence that MAP may be transmitted to humans through foods derived from cattle with MAP infection.

[Jaw bone orthodontics in dogs]. / Kieferorthopadie bei Hunden.

Orthodontics is the branch of dentistry that is concerned with the diagnosis and treatment of malocclusion and related skeletal disorders. The different breeds of dogs show marked variations in occlusion based on the skeletal morphology of the breed. Any malocclusion that is considered genetic, or is suspected of being genetic, should be treated orthodontically, unless the malocclusion is causing, or may cause, an oral problem. If breeding pets have a genetic malocclusion, orthodontic corrective procedures are considered unethical and should only be performed if the pet is neutered, or if you are convinced that the owner does not plan on breeding or showing. Any malocclusion that is considered acquired can be corrected orthodontically. The author described three clinical cases of acquired malocclusion. These cases treat of caudally inclined teeth (retrusion), rostrally inclined teeth (protrusion) and lingually displaced teeth (oral). The treatments were done with expansion screws, elastic power chains, buttons, hooks and brackets.
