ABSTRACT

CASE DESCRIPTION: An 8-month-old spayed female domestic ferret (Mustela putorius furo) was referred for examination to determine the cause of lethargy and severe anemia. CLINICAL FINDINGS: Initial examination revealed that the ferret was lethargic but with appropriate mentation. The only other abnormal findings were severe pallor of the mucous membranes, nasal planum, and skin and a PCV of 8%. Pure red cell aplasia (PRCA) was diagnosed on the basis of cytologic evaluation of a bone marrow biopsy specimen. TREATMENT AND OUTCOME: Medical treatment included blood transfusions, IM administration of iron dextran, oral administration of antimicrobials and gastrointestinal tract protectants, and SC administration of erythropoietin. Once PRCA was diagnosed, the ferret was orally administered prednisone, cyclosporine, and azathioprine. Nine months after onset of treatment, the PRCA was in remission and the ferret was doing well. Immunosuppressive treatment was discontinued at 14 months after onset of treatment, and 36 months after initial examination, the ferret appeared to be healthy. CLINICAL RELEVANCE: It is important that PRCA be considered as a differential diagnosis for a ferret with severe anemia. Prolonged immunosuppressive treatment was successful in the ferret described here.

ABSTRACT

BACKGROUND: Myelin-like material in canine cerebrospinal fluid (CSF) specimens has been attributed to demyelinating or myelomalacic conditions. In our experience, myelin-like material is observed frequently, especially in lumbar samples, and in a variety of disease conditions. OBJECTIVES: The objective of this study was to determine if there are associations between the presence of myelin-like material and CSF collection site, body weight, underlying disease, and patient outcome. METHODS: Wright-Giemsa-stained cytocentrifuged specimens of CSF from the cerebellomedullary cistern (n=51) and lumbar cistern (n=47) of 98 dogs with neurologic disease were evaluated retrospectively for the presence and amount of extracellular myelin-like material. Results were compared based on collection site, body weight, type of neurologic disease, and outcome. RESULTS: Myelin-like material was observed in 20/98 (20%) samples and was more frequently observed in lumbar (17/47, 36%) than cerebellomedullary samples (3/51, 6%) (P=.0028). Samples from dogs <10 kg were more likely to contain myelin (14/36, 39%) compared with dogs > or =10 kg (5/60, 8%) (P=.0052). Larger amounts of myelin-like material were observed in CSF from dogs with intervertebral disk disease compared with other diseases (P=.045). No association was found between myelin-like material and outcome. CONCLUSION: The association of extracellular myelin-like material in canine CSF samples with sampling site and body weight suggests it is more often an artifact of collection technique and anatomy rather than the result of neurologic disease. Myelin-like material in CSF is not associated with a poorer prognosis.
