Evaluation of relationship between plasma fibrinogen concentration and tuberculin testing in red deer.

After intradermal injection of bovine purified derivative (PPD), increases in plasma fibrinogen concentration and plasma viscosity developed in red deer (Cervus elaphus) with a history of tuberculosis caused by Mycobacterium bovis. Serum haptoglobin concentrations were also found to increase under similar circumstances. The increases were reproducible and did not appear to be related to mustering, stress, or the handling associated with injection of PPD. A significant (P less than 0.05) direct relationship was found between the increase in plasma fibrinogen concentration and various markers of bovine tuberculosis infection, such as stimulation of lymphocyte transformation in response to bovine PPD and the diameter of intradermal tuberculin skin test reactions. A stronger correlation (P less than 0.01) was found with the volume of intradermal tuberculin skin test reactivity, and the strongest correlation (P less than 0.001) was with the presence of circulating antibovine PPD antibody.

Effect of physical restraint and xylazine sedation on haematological values in red deer (Cervus elaphus).

Blood samples were taken from healthy red deer (Cervus elaphus) using physical restraint or xylazine sedation. Red and white cell and platelet parameters were measured using a Technicon H6000/C analyser. Lower circulating red cell mass, lymphocyte and platelet counts were found in sedated deer. Mean red cell volume was significantly lower, probably due to the preferential sequestration of young red cells in the spleen. While the main cause of the observed differences is likely to be splenic contraction during physical restraint, the lower plasma viscosity and fibrinogen are suggestive of a haemodynamic component.

Peripheral synovial sarcoma metastatic to the temporal bone.

Peripheral synovial sarcoma rarely metastasizes to the head and neck. A case report of such an occurrence involving the ear is presented, along with a review of the subject. The case report is unique, as it is the only reported instance of synovial sarcoma involving the ear.
