Findings and prognostic indicators of outcomes for bitches with pyometra treated surgically in a nonspecialized setting.

OBJECTIVE: To determine the rate of survival to hospital discharge and identify indicators associated with poor outcomes among female dogs (bitches) with pyometra treated with ovariohysterectomy (OHE) in a nonspecialized setting. ANIMALS: 405 bitches diagnosed with pyometra at the American Society for the Prevention of Cruelty to Animals Animal Hospital from January 1, 2017, to February 8, 2019. PROCEDURES: For this retrospective study, medical records were searched and data collected including patient history, clinical signs, serum biochemical analyses results, and outcome (survival to hospital discharge, length of hospital stay, and uterine rupture). Logistic regression models were used to assess multivariable associations and identify potential predictive variables. RESULTS: The rate of survival to hospital discharge for bitches with pyometra treated with OHE was 97% (394/405); 44% (174/394) stayed in the hospital ≥ 2 nights, and 3% (11/390) had a ruptured uterus. Bitches with a high BUN concentration or heart murmur had greater odds of death after OHE; however, the model had low predictive power. Those with uterine rupture, inappetence, high concentrations of BUN or serum creatinine, low PCV, or dehydration had greater odds of hospitalization ≥ 2 nights. There were no significant predictors of uterine rupture. CLINICAL RELEVANCE: The rate of survival to hospital discharge was high for bitches with pyometra treated with OHE in a nonspecialized setting; therefore, general practitioners could expect similar outcomes. With this important procedure widely available in general practices, more pets can receive treatment for this life-threatening disease.

Owner-reported long-term outcomes, quality of life, and longevity after hospital discharge following surgical treatment of pyometra in bitches and queens.

OBJECTIVE: Investigate long-term complications, survival times, general health and quality of life (QoL) outcomes, and longevity in female dogs and cats (bitches and queens, respectively) following hospital discharge after ovariohysterectomy (OHE) for pyometra. ANIMALS: 306 pet-owner-completed surveys and corresponding medical records for 234 bitches and 72 queens treated with OHE for pyometra at the American Society for the Prevention of Cruelty to Animals Animal Hospital between January 1, 2017, and December 31, 2019. PROCEDURES: A telephone and online survey was conducted to gather data about pet owners' perception of pet health and QoL following OHE for pyometra, and potential associations between survey results and medical record data were evaluated. Median survival time at a given age at OHE for pyometra was calculated with the use of maximum likelihood estimation of a survival-time regression model. RESULTS: 72 of the 121 (60%) eligible owners of queens and 234 of the 390 (60%) eligible owners of bitches completed the survey. Most owners reported that at the time of the survey, their pet's health and QoL were better or the same as before pyometra. Reported health and QoL outcomes were similar for pets > 8 versus ≤ 8 years of age. CLINICAL RELEVANCE: Our findings indicated that bitches and queens undergoing OHE for pyometra at older ages and without other severe health issues can expect to live their full life span. Veterinarians in private practice could expect similar outcomes.

Findings and prognostic indicators of outcomes for queens with pyometra treated surgically in a nonspecialized hospital setting.

OBJECTIVE: To describe findings, determine the rate of survival to hospital discharge, and identify prognostic indicators of poor outcomes for female cats (queens) with pyometra treated with ovariohysterectomy (OHE) in a nonspecialized setting. ANIMALS: 134 queens with pyometra diagnosed between January 1, 2017, and December 31, 2019. PROCEDURES: The medical records were retrospectively searched and data including patient history, clinical signs, blood work results, and outcome (survival to hospital discharge, length of hospitalization, and uterine rupture) were collected from medical records. Logistic regression models were used to assess potential predictors of outcomes. RESULTS: Dehydration (69% [83/121]) and absolute neutrophilia (83% [52/63]) were commonly reported. The rate of survival to hospital discharge was 100% (126/126; 95% CI, 97% to 100%) for queens treated with OHE; 33% (41/126) were hospitalized ≥ 2 nights, and 4% (5/120) had uterine rupture. Queens with abnormal serum ionized calcium concentration or signs of depressed mentation had greater odds (OR of 4.64 and 2.26, respectively) of ≥ 2 nights' hospitalization. Queens with high rectal temperature, closed pyometra, or heart murmur had greater odds (OR of 35.66, 17.37, or 16.06, respectively) of uterine rupture. CLINICAL RELEVANCE: Our findings indicated that OHE for pyometra in queens was highly successful even when performed in a nonspecialty hospital with high-quality basic supportive care, and we believe most general practitioners who offer OHE could expect to see similar outcomes. With more general-practice veterinarians comfortable treating pyometra in their clinics, OHE for pyometra will be available to more pets, ultimately saving more lives.

Welfare of cats 5-29 months after perineal urethrostomy: 74 cases (2015-2017).

OBJECTIVES: The objective of this study was to evaluate the long-term quality of life in cats following perineal urethrostomy. METHODS: This study comprised a retrospective case series of 74 cats with urinary obstructions that received perineal urethrostomies at the American Society for the Prevention of Cruelty to Animals (ASPCA) Animal Hospital between September 2015 and July 2017. Medical records were reviewed for information on the number of obstructions prior to surgery, urinary tract problems at the time of surgery and other potential factors influencing long-term welfare. Owners were surveyed by telephone and text 5-29 months after their cat's surgery. Responses were compiled and analyzed to determine owner perception of welfare postsurgery, and to identify patterns in medical history and welfare outcomes. RESULTS: In total, 105 cat owners were eligible for the survey; 74 responded. Altogether, 100% of responding individuals reported at least the same quality of life postsurgery compared with the cat's quality of life before demonstrating urinary problems (48% reported better). On a quality-of-life scale of 1-10 (10 = excellent), 100% of responding cat owners reported at least 7; 75% reported 10. CONCLUSIONS AND RELEVANCE: Quality-of-life outcomes for cats 5-29 months after receiving perineal urethrostomy surgery were reported to be very good. Given this finding, and that perineal urethrostomy surgery should mitigate future blockages, we suggest considering perineal urethrostomy surgery as a standard tool to manage urinary obstructions in cats. The needs of the specific client and patient, including risks, costs and welfare of the cats, should drive the options for management of urinary obstructions in male cats.

Common Rodenticide Toxicoses in Small Animals.

This article focuses on the 3 most commonly used rodenticide types: anticoagulants, bromethalin, and cholecalciferol. It is important to verify the active ingredient in any rodenticide exposure. Many owners use the term D-con to refer to any rodenticide regardless of the brand or type of rodenticide. The Environmental Protection Agency released their final ruling on rodenticide risk mitigation measures in 2008 and all products sold had to be compliant by June 2011, changing to consumer products containing either first-generation anticoagulants or nonanticoagulants, including bromethalin and cholecalciferol. These regulations have caused an increase in the number of bromethalin and cholecalciferol cases.

Second-generation Anticoagulant Rodenticide Poisoning in a Captive Andean Condor (Vultur gryphus).

A 28-year-old female Andean condor (Vultur gryphus) housed in an outside exhibit at the National Aviary in Pittsburgh, PA, began showing signs of weakness. Toxicosis with an anticoagulant rodenticide was suspected because its mate had died 1 day earlier from possible brodifacoum poisoning. A rapid decline in the packed cell volume, despite vitamin K1 treatment, necessitated a blood transfusion with blood from bald eagles (Haliaeetus leucocephalus) and Steller's sea eagles (Haliaeetus pelagicus). Supportive therapy after transfusion included vitamin K1 (5 mg/kg IM q12h) as well as enrofloxacin, vitamin B complex, selenium and vitamin E, and subcutaneous fluids as needed. After a 39-day treatment period, a tapering dosage of vitamin K1 was initiated, and treatment ended after 17 weeks. However, 2 weeks later, the bird suffered from a potential relapse. It was successfully treated with a repeat tapering vitamin K1 regimen lasting a total of 4 months.

Successful use of digoxin-specific immune Fab in the treatment of severe Nerium oleander toxicosis in a dog.

OBJECTIVE: To describe a case in which digoxin-specific immune Fab was used successfully in a dog with severe oleander toxicosis secondary to ingesting plant material. CASE SUMMARY: A 6-year-old intact female Rhodesian Ridgeback mixed breed dog was presented for severe oleander toxicosis and was refractory to all antiarrhythmic therapies and supportive care. Digoxin-specific immune Fab was successful in treating this dog. The dog recovered but suffered ischemic injuries, the long-term effects of which are unknown. NEW OR UNIQUE INFORMATION PROVIDED: This report describes the successful use of digoxin-specific immune Fab in the treatment of oleander toxicosis in a dog, which has not previously been published in veterinary literature. Oleander poisoning can be associated with permanent cardiac arrhythmias due to the ischemic damage.

Mountain laurel toxicosis in a dog.

OBJECTIVE: To describe a case of mountain laurel (Kalmia latifolia) toxicosis in a dog, including case management and successful outcome. CASE SUMMARY: A dog presented for vomiting, hematochezia, bradycardia, weakness, and ataxia, which did not improve with supportive treatment. Mountain laurel ingestion was identified as cause of clinical signs after gastrotomy was performed to remove stomach contents. Supportive treatment was continued and the dog made a full recovery. NEW OR UNIQUE INFORMATION PROVIDED: This report details a case of mountain laurel toxicosis in a dog, including management strategies and outcome, which has not been previously published in the veterinary literature.

This article focuses on the 3 most commonly used rodenticide types: anticoagulants, bromethalin, and cholecalciferol. It is important to verify the active ingredient in any rodenticide exposure. Many animal owners may use the term "D-con" to refer to any rodenticide regardless of the actual brand name or type of rodenticide. The EPA released their final ruling on rodenticide risk mitigation measures in 2008 and all the products on the market had to be compliant by June 2011, changing to consumer products containing either first-generation anticoagulants or nonanticoagulants including bromethalin and cholecalciferol. These regulations are likely to cause an increase in the number of bromethalin and cholecalciferol cases.
