This is the first report of generalized hypothalamic-pituitary dysfunction or panhypopituitarism following traumatic brain injury in a dog.

Objective To describe the clinical features, clinicopathological features, treatment, and outcome of dogs presented for albuterol exposure. Design Retrospective case series from January 2007 to December 2017. Setting Tertiary veterinary facility. Animals Thirty‐six client‐owned dogs presenting for known or suspected albuterol exposure secondary to chewing on albuterol metered‐dose inhalers (MDIs). Interventions None. Measurements and main results All dogs presented with clinical signs attributable to albuterol exposure. The most common physical examination abnormality was sinus tachycardia, noted in 34 of 36 (94%) dogs. Twenty‐seven patients (75%) were admitted to the hospital for therapy, with a median length of hospitalization of 20.5 hours (16.75–24.5). Thirty‐two of 36 dogs had serum electrolytes evaluated at admission, with 22 of 32 (69%) presenting with hypokalemia ([K+] < 3.62 mmol/L]). Hyperlactatemia ([lactate] > 2.80 mmol/L) was noted in 23 of 28 (82%) dogs. A negative correlation was found between serum lactate and potassium (r = –0.64, r2 = 0.40, P = 0.0003). Hyperglycemia ([glucose] > 6.44 mmol/L) was noted in 20 of 30 (67%) dogs. Beta antagonist therapy was utilized in 20 of 36 (56%) of dogs. Conclusions Although uncommon, albuterol intoxication can lead to significant clinical and electrolyte abnormalities. Albuterol‐induced hypokalemia and associated tachyarrhythmias can be successfully managed, and albuterol intoxication has an excellent prognosis for survival to discharge. A minimum database should be evaluated in all dogs presenting for suspected albuterol exposure, with lactate and glucose monitored carefully in dogs with moderate or severe hypokalemia given the correlation found.

In this study of patients with AKI, fenoldopam administration at 0.8 μg/kg/min in dogs and 0.5 μg/kg/min in cats appeared relatively safe but was not associated with improvement in survival to discharge, length of hospital stay, or improvement in renal biochemical parameters when compared to patients with AKI not receiving fenoldopam.

Antifibrinolytic drugs are used to promote hemostasis and decrease the need for red blood cell transfusion. Medical records of 122 dogs that were prescribed either oral or intravenous aminocaproic acid between 2010 and 2012 were evaluated retrospectively. Of the 122 dogs, three experienced possible drug-related adverse effects. No significant differences were identified between dogs that experienced adverse effects and those that did not and the possible adverse effects noted were all minor. All dogs that received packed red blood cell transfusions were evaluated for correlations between baseline packed cell volume or dose of red blood cells and aminocaproic acid dose and no correlation was identified. Dogs that received aminocaproic acid as a treatment for active bleeding were divided by cause of hemorrhage into the following groups: neoplastic, non-neoplastic, and unknown. No significant differences in aminocaproic acid dose or the percentage of patients requiring a blood transfusion were identified between groups.

Objective: To evaluate bacterial isolates, antimicrobial drug susceptibility, and change in resistance among pre-and post-lavage culture samples in dogs with septic peritonitis. Design: Prospective observational study.Setting: Private practice referral hospital.Animals: Forty client-owned dogs with confirmed septic peritonitis requiring surgical intervention.Interventions: All dogs had perioperative abdominal lavage following source control with 200 to 300 mL/kg 0.9% sterile saline. Pre-and post-lavage aerobic and anaerobic culture samples were evaluated. Measurements and Main Results:Thirty-five of 40 dogs (87.5%) survived to hospital discharge.The likelihood of an aerobic organism to have multidrug resistance (resistance to 3 or more antimicrobial classes) post-lavage was a third of that pre-lavage (odds ratio [OR] 0.34, 95% CI [0.17-0.68], P = 0.01). Thirty-nine of 40 dogs (97.5%) received appropriate empiric antimicrobial therapy based on pre-and post-lavage culture results, of which 5 (12.8%) did not survive to discharge. The single dog with inappropriate antimicrobial therapy survived to discharge. The most frequent isolates detected included Escherichia coli, Clostridium perfringens, and Enterococcus faecalis. The same organism based on species was isolated in pre-and post-lavage cultures in 32 dogs, accounting for 59 anaerobic and aerobic isolates. There was a new bacterial isolate detected in 20 dogs, accounting for 46 isolates and an overall total decrease of 14 isolates between pre-and post-lavage culture (P = 0.09). Conclusions:This study suggests that there is a significant decrease in the likelihood of isolating a multidrug resistant organism following peritoneal lavage, and aerobic and anaerobic culture results have the potential to change following peritoneal lavage, although this cannot be confirmed without further studies. Overall survival rates were higher than previously reported in the literature for septic peritonitis.
