CPA has been described as a cause of ischemic injury to the pituitary gland resulting in CDI in people. To the authors' knowledge, this is the first report of a dog developing transient partial CDI following CPA and successful resuscitation.

Key Clinical MessageLamotrigine is a sodium and calcium channel blocker, used to treat seizures in people. Dogs metabolize Lamotrigine to a cardiotoxic metabolite that causes severe, often fatal ventricular arrhythmias. This report documents the successful treatment of refractory Lamotrigine cardiotoxicity in a dog, using intralipid emulsion therapy.

Key Clinical MessageXylitol and serotonergic compounds are included in the manufacture of numerous over‐the‐counter products. Both compounds have been documented to cause toxicosis in dogs. This report details the first case of simultaneous xylitol toxicosis and serotonin‐like syndrome in a dog, secondary to ingestion of a single over‐the‐counter product.

Calcium‐channel blockers (CCBs) are widely used in people and animals. Overdose can result in cardiovascular collapse and death. Hyperinsulinemia/euglycemia therapy (HIET) and intralipid therapy (ILT) are reported treatment options in people. This is the first report describing HIET and ILT as treatments for amlodipine toxicosis in a cat.

Objective To evaluate criteria used for diagnosis of ventilator‐associated pneumonia (VAP) in dogs and to determine whether appropriate empiric antimicrobial therapy affects outcome. Design Retrospective observational study from 2012 to 2016. Setting Private small animal emergency and specialty center. Animals Thirteen client‐owned dogs requiring positive‐pressure ventilation for over 48 hours. Measurements and main results Medical records of dogs requiring mechanical ventilation (MV) were reviewed. Dogs receiving MV for over 48 hours that had endotracheal lavages (ETL) and thoracic radiographs performed both at initiation of MV and at 48 hours were included. Signalment, body weight, temperature, reason for MV, WBC count, cytology, and semiquantitative aerobic cultures obtained via ETL were recorded. Outcome was defined as survival to discharge or nonsurvival (euthanasia). Six patients (46.2%) were diagnosed with VAP based on the presence of a new bacterial isolate identified on ETL culture at 48 hours. All patients with VAP had new pulmonary infiltrates present on radiographs. The majority of patients with VAP had a leukocytosis (4/6; 66.7%). Six patients (46.2%) survived to discharge. Of the survivors, 3 of 6 (50%) had VAP. Conclusions Bacterial cultures should be obtained at initiation of MV and at 48 hours. A diagnosis of VAP should be suspected in patients that have a new bacterial isolate identified by ETL culture at 48 hours. Radiographic changes and an increase in WBC count may help support a diagnosis of VAP, while culture results are pending. Further studies are needed to evaluate the effect of appropriate antimicrobial therapy on patient outcome.
