Methicillin-resistant Staphylococcus aureus (MRSA) has become a pathogen of animals. To compare types of infections, clinical outcomes, and risk factors associated with MRSA in dogs with those associated with methicillin-susceptible Staphylococcus aureus (MSSA) infections, we conducted a case - control study at 3 veterinary referral hospitals in the United States and Canada during 2001-2007. Risk factors analyzed were signalment, medical and surgical history, and infection site. Among 40 dogs with MRSA and 80 with MSSA infections, highest prevalence of both infections was found in skin and ears. Although most (92.3%) dogs with MRSA infections were discharged from the hospital, we found that significant risk factors for MRSA infection were receipt of antimicrobial drugs (odds ratio [OR] 3.84, p = 0.02), β-lactams (OR 3.58, p = 0.04), or fluoroquinolones (OR 5.34, p = 0.01), and intravenous catheterization (OR 3.72, p = 0.02). Prudent use of antimicrobial drugs in veterinary hospitals is advised.

This report describes a case of feline dystrophin-deficient muscular dystrophy (DDMD) with an atypical clinical presentation. A novel gene mutation is reported to be responsible for dystrophin-deficient hypertrophic muscular dystrophy. In an emergency setting, clinicians should be aware of muscular dystrophy in young cats and the importance of elevated creatine kinase (CK) activity. Muscular dystrophy is rare but can present both a diagnostic and therapeutic challenge in an emergency setting. Patients with muscular dystrophy have a progressive disease with no specific treatment and have an increased risk for death during their hospital stay. © 2014 by American Animal Hospital Association.

Purpose Imaging biomarkers of resistance to radiation therapy can inform and guide treatment management. Most studies have so far focused on assessing a single imaging biomarker. The goal of this study was to explore a number of different molecular imaging biomarkers as surrogates of resistance to radiation therapy. Methods and Materials Twenty-two canine patients with spontaneous sinonasal tumors were treated with accelerated hypofractionated radiation therapy, receiving either 10 fractions of 4.2 Gy each or 10 fractions of 5.0 Gy each to the gross tumor volume. Patients underwent fluorodeoxyglucose (FDG)-, fluorothymidine (FLT)-, and Cu(II)-diacetyl-bis(N4-methylthiosemicarbazone) (Cu-ATSM)-labeled positron emission tomography/computed tomography (PET/CT) imaging before therapy and FLT and Cu-ATSM PET/CT imaging during therapy. In addition to conventional maximum and mean standardized uptake values (SUVmax; SUVmean) measurements, imaging metrics providing response and spatiotemporal information were extracted for each patient. Progression-free survival was assessed according to response evaluation criteria in solid tumor. The prognostic value of each imaging biomarker was evaluated using univariable Cox proportional hazards regression. Multivariable analysis was also performed but was restricted to 2 predictor variables due to the limited number of patients. The best bivariable model was selected according to pseudo-R2. Results The following variables were significantly associated with poor clinical outcome following radiation therapy according to univariable analysis: tumor volume (P=.011), midtreatment FLT SUVmean (P=.018), and midtreatment FLT SUVmax (P=.006). Large decreases in FLT SUVmean from pretreatment to midtreatment were associated with worse clinical outcome (P=.013). In the bivariable model, the best 2-variable combination for predicting poor outcome was high midtreatment FLT SUVmax (P=.022) in combination with large FLT response from pretreatment to midtreatment (P=.041). Conclusions In addition to tumor volume, pronounced tumor proliferative response quantified using FLT PET, especially when associated with high residual FLT PET at midtreatment, is a negative prognostic biomarker of outcome in canine tumors following radiation therapy. Neither FDG PET nor Cu-ATSM PET were predictive of outcome. © 2015 Elsevier Inc. All rights reserved.

Case Description—5 dogs (a Newfoundland, Golden Retriever, Shiba Inu, Staffordshire Terrier, and Vizsla) were referred for evaluation and treatment of unilateral aural hematomas within a week after their formation.Clinical Findings—Aural hematomas involved the left (3) or right (2) ears.Treatment and Outcome—With patients under anesthesia, the aural hematomas were approached surgically from the convex, or lateral, pinnal surface. Two small incisions were used to position a vacuum drain into the incised hematoma cavity. The drain exited at the base of the pinna and adjacent cervical skin. The free end of the drain was attached to a vacuum reservoir for 18 to 21 days. Drains and skin sutures were removed at this time along with the protective Elizabethan collar. All hematomas resolved and surgical sites healed during the minimum 6-month follow-up period. Cosmetic results were considered excellent in 4 of 5 patients. Slight wrinkling of the pinna in 1 patient resulted from asymmetric enlargement of the cartilaginous walls of the hematoma, where vacuum application resulted in a slight folding of the redundant lateral cartilage wall.Clinical Relevance—The described treatment was efficient, economical, and minimally invasive and required no bandaging or wound care. Placement of the drain tubing on the convex (lateral) aspect sheltered the system from displacement by patients with an Elizabethan collar in place. Overall cosmetic results were excellent; asymmetric enlargement of the cartilaginous walls of the hematoma with slight folding of the pinna was seen in 1 patient. © 2015, American Veterinary Medical Association.

Early recognition of failure of oxygen delivery and knowledge of how medications can alter oxygen delivery allow clinicians to institute appropriate therapies in a timely manner and can result in improved patient outcomes. Oxygen delivery can be estimated and evaluated using a variety of methods, including arterial blood gas sampling, blood lactate quantification, echocardiography, and direct cardiac output measurement. Delivery can be enhanced by manipulating the components of the oxygen delivery formula. Cardiac output, hemoglobin concentration, oxygen saturation, and oxygen tension can all be improved through therapeutic or pharmacologic intervention.

This study evaluated four over the counter venison dry dog foods available from one on-line retail vendor for potential contamination with common known food allergens: soy, poultry or beef. An amplified, double sandwich type enzyme linked immunosorbent assay (ELISA) test of soy, poultry and beef proteins were performed by an independent accredited food laboratory. The ELISA test for poultry protein was found to be unreliable when testing in dry dog foods because false negatives occurred. ELISA testing of control diets for both soy and beef proteins performed as expected and could be useful in antigen testing in dry dog foods. Three of the four over the counter (OTC) venison canine dry foods with no soy products named in the ingredient list were ELISA positive for soy; additionally one OTC diet tested positive for beef protein with no beef products listed as an ingredient list. One OTC venison diet was not found to be positive for soy, poultry or beef proteins. However, none of the four OTC venison diets could be considered suitable for a diagnostic elimination trial as they all contained common pet food proteins, some of which were readily identifiable on the label and some that were only detected by ELISA. Therefore, if the four OTC venison products selected in this study are representative of OTC products in general, then the use of OTC venison dry dog foods should not be used during elimination trials in suspected food allergy patients. © 2010 Blackwell Verlag GmbH.

Objective: To describe the medical management of pneumoperitoneum without surgical intervention in a dog that sustained blunt force trauma to the thorax. To review the mechanisms of how a thoracic injury (ie, extra-abdominal source) can lead to pneumoperitoneum. Case Summary: A 4-month-old Shih Tzu puppy was attacked by a larger dog and sustained various injuries including a pneumothorax, pneumomediastinum, and a pneumoperitoneum. The dog presented minimally responsive and in respiratory distress secondary to pulmonary contusions and noncardiogenic pulmonary edema. No penetrating wounds to the abdomen or thorax were identified. As no immediate surgical lesion was identified the dog was treated conservatively without the need for surgical intervention. The dog was successfully managed and discharged after a few days of supportive care with oxygen therapy. Before discharge, repeat radiographs revealed complete resolution of the pneumothorax, pneumomediastinum, and pneumoperitoneum. New or unique information provided: Cases of nonsurgical pneumoperitoneum have rarely been reported in the veterinary literature. A thoracic source of pneumoperitoneum should be considered when the suspicion of a ruptured viscus is low based on diagnostic procedures (eg, ultrasound, computed tomography, and diagnostic peritoneal lavage), in addition to physical examination (eg, lack of fever and absence of abdominal pain) and laboratory findings (eg, absence of inflammatory leukogram). © Veterinary Emergency and Critical Care Society 2011.

Environmental enrichment is of great import to the emotional, intellectual, and physical development of the juvenile psittacine and their success in the human home environment. Five major types of enrichment include social, occupational, physical, sensory, and nutritional. Occupational enrichment includes exercise and psychological enrichment. Physical enrichment includes the cage and accessories and the external home environment. Sensory enrichment may be visual, auditory, tactile, olfactory, or taste oriented. Nutritional enrichment includes variations in appearance, type, and frequency of diet, and treats, novelty, and foraging. Two phases of the preadult period deserve special enrichment considerations: the development of autonomy and puberty. © 2015 Elsevier Inc.

A 1-year-old castrated male St. Bernard dog presented to Angell Animal Medical Center with bilateral elbow hygromas which had been present for several weeks. The largest hygroma involving the left elbow was managed with a closed suction (active) drain system to continuously collapse the hygroma pocket over a 3-week period. Soft bedding was used to protect the elbows from further impact trauma to the olecranon areas. Following drain removal, there was no evidence of hygroma recurrence based on periodic examinations over an 18-month period. The smaller non-operated right elbow hygroma had slightly enlarged during this period. Closed suction drain management of the hygroma proved to be a simple and economical method of collapsing the left elbow hygroma. This closed drainage system eliminated the need for the postoperative bandage care required with the use of the Penrose (passive) drain method of managing elbow hygromas. The external drain tube should be adequately secured in order to minimise the risk of its inadvertent displacement. © 2015 British Small Animal Veterinary Association.
