Neoplasms of the nasal and paranasal sinuses make up approximately 1% of canine tumors. These tumors are malignant in 80 % of the cases, and 60 - 75 % are carcinomas. According to most authors, adenocarcinomas are the most common nasal tumor, followed by squamous cell carcinoma. Large and medium sized dogs in the 8-10 year age group are most commonly affected. Some authors find the dolicocephalic breeds to be the most prone to develop adenocarcinoma, while others find the number of cases higher in the mesocephalic breeds. Some reports show a higher incidence of nasal adenocarcinoma in male dogs, but when correction is made for sex distribution of the number of cases seen, there is no difference in nasal tumor incidence between males and females. There is no known etiological agent for nasal adenocarcinoma, and there is no difference between urban and rural dogs with respect to nasal and sinus neoplasia.

Often we have a misconception of the relationship between ourselves as students and our instructors. Frequently we feel it's "us versus them", and too often it seems the instructors view things the same way. This is detrimental to the learning process. It also leads to a rift in communication between students and instructors. The function of an instructor, however, is not to become a thorn in our flesh. The instructor, rather, is to fulfill the role of a trusted servant who leads his or her charges (that's us) down the pathway of knowledge to the place where we intelligent and hard-working students can become competent veterinarians. The fact that few of us stray from this path is testimony to the abilities of instructors to keep our goal in mind. It may even be that the success of these "institutions of higher learning" which we attend may be due to the instructors spending many long hours in their ivory towers gazing out over the pathway of knowledge looking for potholes to fix and detours to avoid so we can work unhindered (unhindered, at least, by the teacher).

A two-month-old Quarterhorse was presented for evaluation of a severe val gal ('knock-kneed') angulation of the carpi and diarrhea of two to three days' duration. The angular deformity had been present since birth. At one month of age, the foal had experienced pneumonia and a draining tract on the left carpus, but these were not evident on presentation.

Perhaps the greatest tests of a horse's athletic ability and "heart" are the long distance trail ride competitions and combined training events. In no other equestrian competition is a horse's endurance and stamina so challenged. Long distance trail rides are generally grouped into two classifications: competitive and endurance rides. In competitive trail rides, horse and rider cover from 25 to 100 miles in one to three days, depending on the specifications of each ride.
