RESUMO

Linguoverted mandibular canine teeth (LMC) are a common cause of class 1 malocclusion, which may result in a traumatic occlusion. When deciduous LMC are diagnosed, extraction is commonly performed to alleviate traumatic occlusion. This retrospective study was designed to observe the outcome of the permanent dentition in dogs with a class 1 malocclusion receiving treatment for deciduous LMC. Medical records from a veterinary dental referral hospital were used to identify patients that underwent extraction of deciduous LMC's prior to the eruption of the permanent mandibular canine teeth. The permanent occlusion was then evaluated once the permanent mandibular canine teeth were erupting. Of the 28 dogs identified and treated for deciduous LMC's, 78.6% (22/28) had a normal permanent occlusion. The 6 patients identified with permanent LMC's were all diagnosed when the patients were between 20 and 29 weeks of age. Of these 6 patients, 5 received gingivectomy and gingivoplasty treatment to correct the permanent LMC. Treatment was declined by the pet owner of the sixth patient. Overall, the majority of dogs in this study with a class 1 malocclusion and deciduous LMC's treated with extractions prior to the eruption of the permanent mandibular canine teeth had a normal permanent occlusion.

RESUMO

A 1-year-old female Boer goat was presented with a 1-day history of pigmenturia, anorexia, and shivering. Anemia was not present initially, but progressive hemolytic anemia developed subsequently and was characterized by the finding of Heinz bodies in both intact RBCs and in ghost cells and the presence of atypical fusiform RBCs. Plasma biochemical analysis revealed increased activities of aspartate aminotransferase and gamma-glutamyltransferase, hyperbilirubinemia, and azotemia. Histopathologic examination of a liver biopsy revealed necrosis of individual hepatocytes and intracytoplasmic rhodamine-positive granules, consistent with copper. Copper concentration in ante-mortem hepatic tissue was increased, and a diagnosis of copper toxicosis was made. Despite supportive therapy, the goat continued to decline and was euthanized. Necropsy findings included hepatic necrosis and hemoglobinuric nephrosis. Freshly collected specimens of liver and kidney had markedly increased copper concentrations. The mineral composition of the water, grass hay, and goat chow was evaluated, and toxins and significant mineral imbalances were not found. The underlying cause of the hepatic accumulation and subsequent release of copper remains unclear in this goat. Recently, Boer goats have been recognized as being prone to copper toxicosis and may be more susceptible than other breeds; similar to sheep, Boer goats may experience a hemolytic crisis secondary to copper toxicosis.

RESUMO

CASE DESCRIPTION: A 5-year-old castrated male Vietnamese pot-bellied pig (Sus scrofa) was evaluated because of anorexia, vomiting, diarrhea, and weight loss. CLINICAL FINDINGS: Hypermotile gastrointestinal sounds were noted on abdominal auscultation. An inflammatory leukogram, dehydration, prerenal azotemia, hyponatremia, hypochloremia, hyperproteinemia, hyperglobulinemia, hypomagnesemia, and high γ-glutamyl transpeptidase activity were identified. Transabdominal ultrasonography revealed distended loops of small intestine. TREATMENT: IV fluid therapy and analgesic treatment were unsuccessful in the resolution of clinical signs. Exploratory laparotomy revealed an ileocecal intussusception involving the distal portion of the ileum. Distal ileal and cecal bypass were achieved via side-to-side anastomosis of the proximal portion of the ileum and spiral colon with a gastrointestinal anastomosis stapler. Ileal transection or occlusion was not performed. Postoperative complications were minimal, and the pig was clinically normal 15 months after surgery and required no special care or diet. CLINICAL RELEVANCE: Distal ileal and cecal bypass without ileal transection have not been described previously in Vietnamese pot-bellied pigs. Anastomosis of the proximal portion of the ileum to the spiral colon without major complications represents a novel, technically simple approach to bypass of the distal portion of the ileum and cecum.

RESUMO

OBJECTIVE: To describe the successful management of an alpaca with severe hypoventilation and hypercapnia, suspected to be secondary to an anesthesia-related event. CASE SUMMARY: A 3-year-old, female alpaca underwent a routine eye enucleation under general anesthesia after traumatic globe perforation. Severe hypoventilation and associated hypercapnia developed postoperatively resulting in a severe primary respiratory acidosis. The awake alpaca was supported with positive-pressure ventilation for approximately 20 hours before successful weaning. Recovery to hospital discharge occurred over the subsequent 5 days with the alpaca regaining apparently normal respiratory function. NEW OR UNIQUE INFORMATION PROVIDED: To the knowledge of the authors, this is the first report describing positive-pressure ventilation of an alpaca in the veterinary literature. In this case of severe hypoventilation, ventilatory support was essential to the positive outcome. As South American camelids continue to increase in popularity there may be an increased demand for high-quality and sophisticated veterinary care for these animals. Mechanical ventilation can be used to help restore and maintain normal PO2, PCO2, and respiratory acid-base status in alpacas with ventilatory dysfunction.
