ABSTRACT
OBJECTIVE: To describe the clinical signs and outcome following ivermectin overdose in a bearded dragon. This case also describes the novel use of intravenous lipid emulsion (ILE) as a rescue therapy in reptiles, as well as the use of aggressive gastrointestinal decontamination. CASE SUMMARY: A 4-year-old female intact bearded dragon (Pogona vitticeps) (0.6 kg) was admitted to the ICU at a specialty hospital following accidental overdose of 40 mg (66.7 mg/kg) of ivermectin enterally. The patient was physically inverted to allow passive reflux of the medication, then sedated for gastric lavage. A 20% ILE was administered intravenously due to the high risk for fatality. Additional treatments included 2 doses of activated charcoal, as well as SC fluids, enteral nutrition, and sucralfate. The patient was profoundly sedate until day 4 when mild improvements in mentation were noted. The patient started ambulating on its own on day 6 and was discharged from the hospital on day 13. The patient was alive 720 days postdischarge. NEW OR UNIQUE INFORMATION PROVIDED: This is the first case report describing the events following ivermectin overdose and the use of ILE therapy and activated charcoal in a bearded dragon. These therapies were tolerated with no adverse effects noted in this patient. This report provides evidence that complete recovery from ivermectin overdose is possible.

A 7 yr old female spayed Canaan dog was presented for evaluation of a subclinical intrathoracic mass noted during meta-static staging for a digit and lingual mass. Thoracic ultrasound and computed tomography revealed a 6.0 × 5.5 cm mass within the cranial mediastinum. The mass was septated with mixed fluid and soft-tissue structures and no evidence of vascular invasion. Narrow excision of the mass via a sternal thoracotomy was performed. Histopathology of the mass was consistent with a thyroglossal duct cyst adenocarcinoma. This is the first reported case of a thyroglossal duct cyst adenocarcinoma arising in the cranial mediastinum of a dog. There was no evidence of metastasis or recurrence 25 mo after surgery and adjunctive therapy.
ABSTRACT
OBJECTIVE: To describe 4 cases of tracheal narrowing attributed to tracheal mucosal hemorrhage caused by anticoagulant rodenticide toxicity in breeds predisposed to tracheal collapse. CASE SUMMARY: Over the years 2005-2014, 4 dogs were presented for respiratory distress secondary to diffuse tracheal narrowing. All dogs had possible anticoagulant rodenticide ingestion and prolonged prothrombin time. All dogs received fresh-frozen plasma transfusions, vitamin K1 supplementation, and supportive care. Tracheal narrowing improved on follow-up radiographs in 3 of 4 patients. One of 4 did not have follow-up radiographs performed. All dogs survived. NEW OR UNIQUE INFORMATION PROVIDED: Anticoagulant rodenticide toxicity causing clinical signs consistent with tracheal collapse is a rare but recognized phenomenon that has not been previously reported in breeds prone to tracheal collapse.
