A 7-year-old neutered male Shih Tzu presented with acute onset of progressive tetraparesis and generalized muscle atrophy. Neurological examination, electromyography (EMG), and muscle biopsy revealed findings consistent with denervation-induced muscular atrophy. Based on these results, a tentative diagnosis of immune-mediated neurogenic myopathy was established. Immunosuppressive therapy with cyclosporine and mycophenolate mofetil led to a marked clinical improvement. However, relapse following discontinuation of therapy indicated the chronic relapsing nature of the disease. This case demonstrates the diagnostic value of EMG and muscle biopsy in identifying neuromuscular disorders and underscores the importance of a multimodal diagnostic approach for the accurate diagnosis and management of suspected neurogenic myopathies.

Canine T-zone lymphoma (TZL) is a mature T-cell lymphoma in dogs. The diagnosis and sub-classification are impossible without biopsy or immunophenotyping by flow cytometry. An 11-year-old, spayed, female Golden Retriever presented with lymph node enlargement. Clinical examination was consistent with canine multicentric lymphoma. However, immunophenotyping revealed positive for CD3, CD4, CD5, CD8, CD21, TCRαβ, and MHCII but negative for CD34, CD45, CD79a, and TCRγδ. Histopathology revealed lymphocytes expanding to the cortex-preserving architecture and thinning of the nodal capsule, and CD3 positive but PAX-5 negative. Owing to the indolent nature of TZL, careful monitoring approach without clinical intervention was utilized.

This report describes the first clinical case of a transfusion-associated Mycoplasma haemocanis infection in a dog in Korea. A 6-year-old male Maltese underwent a red blood cell transfusion for idiopathic immune-mediated hemolytic anemia. Eighteen days after the blood transfusion, the recipient’s packed cell volume decreased and basophilic organisms were found on erythrocytes. A polymerase chain reaction and sequential analysis showed that both the donor dog and recipient dog had M. haemocanis. Six weeks after doxycycline administration, no organisms were detected and the recipient’s anemia had improved.

Routine preoperative tests such as BT/CT, PT/PTT and CBC, could not test abnormal hemostasis that take drugs and health functional food. We used platelet function analyzer (PFA(R))-100, to evaluate preoperative bleeding tendencies. From November 2008 to February 2010, 306 surgical patients were tested preoperative PFA in our hospital. There are 2 tests in PFA(R)-100. The Pre Operative EPI (collagen/epinephrine) assay tests extrinsic platelet function, whereas the Pre Operative ADP (collagen/adenosine diphosphate) assay tests intrinsic platelet function. We divided normal and abnormal groups by the PFA(R)-100 assay tests. If either of results were abnormal in the two tests, the patient was divided to the abnormal group. 306 surgical patients were observed with hemorrhagic complications. All of the patients were divided normal and abnormal groups by the PFA(R)-100 test result. The normal group was made up of 286 (93.5%) patients, the abnormal group was made up of 20 (6.5%) patients. We observed each group hemorrhage complication including sever echymosis and hematoma, and analyzed each group complication rate. There were 9 (3.1%) cases of complication in the normal group. There were 3 (15.0%) cases of complication in the abnormal group. To evaluate preoperative bleeding tendency, PFA(R)-100 can be complementary examination with previous routine blood coagulation tests.
