Objective: To evaluate the effects of intravenous (IV) infusion of fish oil (FO) emulsion following ovariohysterectomy (OVH) on inflammatory mediators and plasma omega-3 nonesterified fatty acids (NEFA) concentrations in dogs.

Design: Prospective clinical study.

Setting: University teaching hospital.

Core curriculum illustration: pneumothorax.

This is the fourth installment of a series that will highlight one case per publication issue from the bank of cases available online as part of the American Society of Emergency Radiology (ASER) educational resources. Our goal is to generate more interest in and use of our online materials. To view more cases online, please visit the ASER Core Curriculum and Recommendations for Study online at http://www.

Comparison of two portable lactate meters in dogs.

The objective of this study was to compare two portable lactate analyzers for testing canine patients in a clinical setting with a previously accepted methodology for measuring plasma lactate. Between Jan 1, 2005 and Jun 1, 2006, all samples were analyzed using two different portable analyzers (devices A and B), and 86 of those samples were also analyzed by a reference laboratory (REF). The concordance correlation coefficient (CCC) for device A and the REF was 0.

Radiology-Pathology Conference: 18F FDG PET-CT imaging of solitary fibrous tumor of the pleura.

Solitary fibrous tumors of the pleura (SFTPs) are mesenchymal neoplasms that arise from the pleura. SFTPs can grow slowly and may become big masses with malignant behaviors and metastases. The ratio of benign to malignant is 7:1, and pathology is necessary to differentiate between benign and malignant.

Development of a rapid sanitization solution for silica-based protein A affinity adsorbents.

Protein A chromatography media require sanitization between batches as well as prior to long-term storage. While sodium hydroxide (NaOH) is probably one of the most widely used sanitants within the bioprocess industry, it cannot be used with silica- or controlled pore glass (CPG)-based adsorbents due to the instability of the base matrix at high pH. Benzyl alcohol is commonly used for sanitizing such adsorbents, though extended contact times may be required to meet desired microbial log reduction values, especially for fungal and bacterial spore formers.

Chest radiographic evolution in fat embolism syndrome.

Objective: To characterize the temporal chest radiographic findings of fat embolism syndrome.

Material And Method: Twenty-nine patients with clinically diagnosed fat embolism syndrome between 1988-1999 were retrospectively identified from the Trauma Registry of Haborview Medical Center, University of Washington. In twenty-two patients, complete medical records and serial chest radiographs were available.

The misdiagnosis of acute cervical spine injuries and fractures in infants and children: the 12-year experience of a level I pediatric and adult trauma center.

Objective: The objective was to determine the frequency of acute cervical spine injuries and fractures that were misdiagnosed in infants and children (< or =14 years) initially evaluated at a pediatric and adult urban level I trauma center.

Methods And Results: This was a retrospective, single-institution, case series of pediatric cervical spine injuries and fractures that were misdiagnosed during initial emergency room imaging evaluation. "Misdiagnosed" cases were those cases whose imaging studies initially obtained in the emergency room were misinterpreted based on reevaluation by a senior trauma radiologist blinded to the initial results.

Major glossectomy in dogs: a case series and proposed classification system.

Major resections of the tongue have not been commonly performed in animals because of concerns about the unfavorable postoperative effects of diminished lingual function. Five dogs were retrospectively reviewed to determine prehensile function and quality of life after glossectomies. Examinations were performed 1 week to 8 years after glossectomy, and owner interviews were conducted 10 months to 8 years after the surgery.

Use of helical computed tomography for imaging the pediatric cervical spine.

Objective: To determine the differences in resource utilization and radiation exposure between conventional radiography (ConvRad) and helical computed tomography (HCT) when used to survey the pediatric cervical spine (CSp).

Methods: Patients aged 0-14 years who required CSp radiographic evaluation in addition to cranial CT were prospectively enrolled and assigned to undergo either HCT or ConvRad with adjunctive linear tomography. Outcomes of medication usage, emergency department (ED) length of stay (LOS), cervical spine radiation exposure, and imaging resource use (relative value unit [RVU]) were compared between the two groups.

Soft tissue application of lasers.

Despite increasing numbers of veterinarians incorporating lasers into their clinical practices, little information has been published about laser clinical applications in soft tissue surgery. This article reviews soft tissue interaction, describes laser equipment and accessories commonly marketed to veterinarians, and discusses clinical applications of the carbon dioxide laser in a systems-based approach. A table of recommended laser tips and settings based on the authors' experiences using a carbon dioxide laser (AccuVet Novapulse LX-20SP, Bothell, WA) is provided.

Femur fractures in relatively low speed frontal crashes: the possible role of muscle forces.

In a sample of relatively low speed frontal collisions (mean collision speed change of 40.7 kph) the only major injury suffered by the partly or fully restrained occupant was a femur fracture. However, femur load measurements from standardized barrier crash tests for similar vehicles at a greater speed change (mean of 56.

Subchronic Centrifugal Mechanical Assist in an Unheparinized Calf Model.

The purpose of this study was to determine whether the major centrifugal pumps currently in use in the United States (Medtronic, BioMedicus BioPump and Carmeda-coated BioPump, Sams 3M centrifugal pump, and St. Jude Medical Lifestream) could function as left mechanical assist devices in the subchronic (72 h) unheparinized calf model. Calves were instrumented for left atrial to aorta ex vivo assist, and the pump flow was set at 3.

Subchronic Use of the St. Jude Centrifugal Pump as a Mechanical Assist Device in Calves.

The purpose of this experiment was to study the effects of the St. Jude Lifestream centrifugal pump on hemodynamic and hematologic parameters and the incidence of postmortem findings in a subchronic ex vivo left ventricular assist animal model. Five calves were implanted with the pump as a left ventricular assist device (left atrial to thoracic aorta bypass) and studied for 96 h of continuous pumping under identical conditions.

A Calf Model for Left Ventricular Centrifugal Mechanical Assist.

The increased use of centrifugal mechanical assist (CMA) for treatment of refractory postcardiotomy cardiogenic shock highlights the need for experimental testing to improve clinical results. This report describes the preoperative conditioning, anesthetic and surgical technique, and postoperative management of a reliable calf model refined in this laboratory for in vivo sub-chronic (96 h) testing of CMA. Holstein bull calves (2 to 3 months old; mean body weight, 78 kg; n = 35) were instrumented for left ventricular CMA; 4 of these calves were sham-operated controls.
