A Case of Auricular Ossification

Ectopic ossification refers to the process of new bone formation in sites that normally do not ossify. The auricle is composed of elastic cartilage, and hence is a pliable structure. Auricular ossification is a rare condition that might be caused by injurious processes, including frostbite, physical trauma, and inflammation as well as processes related to metabolic or endocrine disorders. Here, we report a case of unilateral auricular ossification in a 53-year-old Korean man who had previously rubbed his ear repeatedly with his hand

Forteen cats were used for the experiments, including 6 infected intraperitoneally, 4-perorally, 2-intraconjunctivally, 1-intratracheally, with one animal serving as a control. An acute course of the disease was found in two cats, subacute in three, and chronic in the remaining animals. One cat, infected perorally was found to be free of toxoplasmosis. Clinical picture of the disease, hematologic, electrophoretic, serologic studies and anatomo-pathologic findings are presented. The results obtained prompt the following conclusions: (1) The course of experimental toxoplasmosis in cats is likely to depend on the age, invasion route, and the material used for infecting purposes. (2) The observed clinical symptoms and anatomo-pathologic alterations do not seem to be typical of this disease. (3) Hematologic and electrophoretic studies are not contributory to the diagnosis. (4) The Sabin-Feldman's dye test apparently reflects the course of the disease, whereas the complement fixation test, for unknown reasons, fails, being negative in majority of cases with toxoplasmosis confirmed by other methods

Two series of examinations were concerned with clinical symptoms, the behaviour of allergic reaction, hematologic changes, electrophoretic and serologic reactions (complement fixation and hemagglutination tests ), as well as post-mortem findings and passages of various organ cultures through mice. The disease was observed in its acute, subacute and chronic form. It is noteworthy that the intravital material from diseased dogs (purulent discharge from the eye, nose, saliva and the content of ulcerations at the site of injection) yielded Toxoplasma gondii. Further experiments are being led
