[Squamous cell carcinoma of the esophagus in a free-living rook]. / Plattenepithelkarzinom des Osophagus bei einer wildlebenden Saatkrähe.

In a free living rook (Corvus frugilegus) a well differentiated squamous cell carcinoma without keratinization arising from the oesophageal mucosa was found. This tumour had grown around the right main bronchus and so caused marked respiratory distress.

[Trombiculid mite--Neotrombicula autumnalis (Shaw 1790)--in veterinary medicine. Nervous systems in dogs following massive infestation]. / Zur Bedeutung der Herbstgrasmilbe--Neotrombicula autumnalis (Shaw 1790)--in der Veterinärmedizin: Nervale Symptome bei Hunden nach massiver Infestation.

Initially the biology of chigger mites and the clinical course of Trombiculosis is reviewed. This is followed by a case study dealing for the first time with nervous symptoms associated with this disease. Twenty-four hours after a massive infestation of at least 2000 larvae of N. a. autumnalis two male Yorkshire terriers of approximately three years of age showed initial stages of paresis of the rear extremities in a few hours. The lameness worsened to such an extent that the front extremities were also affected and the dogs could no longer stand. After repeated acaricide treatments and symptomatic therapy these nervous symptoms disappeared within three days.
