In this retrospective study of 42 cases of lingual tumors in dogs, 27 (64%) were malignant, and 15 (36%) were benign. Median survival time for dogs with benign tumors was >1607 days, compared to 286 days for malignant tumors. Prognostic factors significantly associated with increased survival included complete histological margins (P=0.036), smaller tumor size (P=0.003), and benign tumor type (P=0.011). Smaller tumors were more likely to be completely resected (P=0.008) and were less likely to recur (P=0.001). Partial or subtotal glossectomies were performed in 13 cases. Short-term morbidity associated with glossectomy included ptyalism and dehiscence. Long-term morbidity included minor changes in eating and drinking habits.
A 4 yr old castrated male Jack Russell terrier was presented with a 2 mo history of vomiting, anorexia, and weight loss. Abdominal radiographs and ultrasound supported the diagnosis of gastric outflow obstruction. Celiotomy and gastrotomy revealed a large, narrowly based mass originating from the mucosa of the dorsal gastric body, occupying the lumen of the stomach and protruding through the pylorus into the duodenum. A partial gastrectomy was performed to excise the mass along with a 1 cm margin of grossly normal tissue. Giant hypertrophic gastritis was diagnosed via histopathology of the excised tissue. Giant hypertrophic gastritis is a rarely diagnosed disease of canines, characterized by giant gastric folds, hypoalbuminemia, and mucosal hypertrophy. Long-term treatment success has not been previously reported. In the case described herein, surgical excision of the affected gastric tissue provided complete resolution of clinical signs. Twelve mo following surgery, no recurrence of either vomiting or weight loss had been noted and the dog was clinically normal.
Pyloric stenosis should be considered a differential diagnosis for young cats with pyloric outflow obstruction. The cat of this report was treated successfully with a Billroth I procedure. Histologic examination and immunohistochemical analysis of the excised tissue showed the stenosis to be associated with hypertrophy of the tunica muscularis.
Cortical thickness and bone density measurements were obtained from multiple regions of the canine humerus using QCT. Use of short monocortical screws may contribute to failure of locking plate fixation of humeral fractures, especially when placed in the condyle. When bicortical screw placement is not possible, maximizing monocortical screw length may optimize fixation stability for distal humeral fractures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
