Canine diffuse idiopathic skeletal hyperostosis.

The radiographic and necropsy findings in a case of canine diffuse idiopathic skeletal hyperostosis are reported. Radiographically, the disease was characterized by progressive development of para-articular mineral densities along joint surfaces of the appendicular skeleton; progressive osseous fusion of the ilium, pubis, femur, and ischium; and progressive flowing ossification of the dorsal spinous processes of cervical and thoracic vertebrae. The para-articular lesions were considered to develop as a consequence of fibrocartilaginous proliferation followed by endochondral ossification. Progression of the ossification process led to para-articular joint fusion and almost complete ossification of the metaplastic cartilage. A distinguishing feature was the sparing of intra-articular structures.

Well-differentiated lymphocytic leukemia in a dog: long-term survival without therapy.

Well-differentiated lymphocytic leukemia was found during routine hematologic examination of a 12-year-old female poodle with signs of anxiousness, panting and pica. The total white blood cell count was 106,900/microliters and at least 90% of the leukocytes were small, normal-appearing lymphocytes. The dog was examined several times during a 23-month period before it was killed at the owner's request for conditions unrelated to the leukemia. The hematologic picture of the leukemia was essentially unchanged during this time. A deep nuclear cleft was seen in most lymphocytes examined by electron microscopy. Cell surface markers showed most blood lymphocytes to be B-cells. These cells responded poorly to mitogen stimulation.

An analysis of skiing injuries in West Virginia.

This study analyzes the injuries of 124 skiers who presented to the emergency department of a hospital near four major ski resorts in West Virginia, and identifies possible prevention strategies. Data was gathered about demographics, nature of injury, causal factors, prevention strategies, and ultimate outcome as measured by disposition. Haddon's method of injury analysis was then applied, dividing cause of injury into host, vehicle, and environmental factors. Most skiers identified host error as cause of injury. Of the 60% of skiers who reported that their injury could have been prevented, most named some form of behavior modification as the most likely prevention strategy. The remaining skiers did not realize that their injury could have been prevented. This finding highlights the need for prevention education to decrease the number of skiing injuries.
