Objectives The aim of the study was to evaluate ultrasonographic changes in the small intestine of cats with clinical signs of gastrointestinal disease and low or low–normal serum cobalamin concentrations. Methods Records for client-owned cats presenting to the small animal hospital with signs of gastrointestinal disease and in which serum cobalamin concentrations were measured from 2000–2013 were reviewed. Inclusion criteria were cobalamin concentrations <500 ng/l, abdominal ultrasound within 1 month of cobalamin testing and definitive diagnosis. Results Of 751 serum cobalamin measurements, hypocobalaminemia or low–normal cobalamin was identified in 270 cats, abdominal ultrasound was performed in 207 of those cats and a diagnosis was available for 75 of them. Small intestinal ultrasound changes were detected in 49/75 (65%) cats. Abnormalities included thickening, loss of wall layer definition, echogenicity alterations and discrete masses. Serum cobalamin concentrations <500 ng/l were observed with diagnoses of inflammatory disease, neoplasia, infectious disease and normal histopathology. Cobalamin concentration was significantly lower in cats with lymphoma or inflammatory bowel disease compared with other gastrointestinal neoplasia ( P = 0.031). No difference was found between cobalamin concentration and the presence of ultrasound abnormalities, specific ultrasound changes or albumin concentration. Conclusions and relevance One-third of symptomatic cats with hypocobalaminemia or low–normal cobalamin concentrations may have an ultrasonographically normal small intestine. For the majority of cats in this study, histopathologic abnormalities were observed in the small intestine, regardless of ultrasound changes. These findings suggest gastrointestinal disease should not be excluded based on low–normal cobalamin concentrations, even with a concurrent normal ultrasound examination. Additional studies are needed in cats with low–normal serum cobalamin concentrations, as a definitive diagnosis was not pursued consistently in those cats. However, data from this study suggest that careful monitoring, histopathologic evaluation and future cobalamin supplementation may be warranted.

AbstractBackgroundThe Focused Assessment with Sonography in Trauma (FAST) exam is a rapid ultrasound test to identify evidence of hemorrhage within the abdomen. Few studies examine the accuracy of paramedic performed FAST examinations. The duration of an ultrasound training program remains controversial. This study's purpose was to assess the accuracy of paramedic FAST exam interpretation following a one hour didactic training session.MethodsThe interpretation of paramedic performed FAST exams was compared to the interpretation of physician performed FAST examinations on a mannequin model containing 300ml of free fluid following a one hour didactic training course. Results were compared using the Chi-square test. Differences in accuracy rate were deemed significant if p < 0.05.ResultsFourteen critical care flight paramedics and four emergency physicians were voluntarily recruited. The critical care paramedics were mostly ultrasound-naive whereas the emergency physicians all had ultrasound training. The correct interpretation of FAST scans was comparable between the two groups with accuracy of 85.6% and 87.5% (∆1.79 95%CI -33.85 to 21.82, p = 0.90) for paramedics and emergency physicians respectively.ConclusionsThis study determined that critical care paramedics were able to use ultrasound to detect free fluid on a simulated mannequin model and interpret the FAST exam with a similar accuracy as experienced emergency physicians following a one hour training course. This suggests the potential use of prehospital ultrasound to aid in the triage and transport decisions of trauma patients while limiting the financial and logistical burden of ultrasound training.
