    Medical records of 16 Japanese Black calves with respiratory signs associated with perinatal rib fracture were analyzed, retrospectively, to speculate criteria of surgical intervention for the disease. For this analysis, the severity of respiratory condition was classified into three grades: Grade 1, with no wheezing, Grade 2, with wheezing after excitement but not at rest and Grade 3, with wheezing at rest. Grade 1 (n=3) received only conservative management. Seven of Grade 2 (n=8) and all of Grade 3 (n=5) had surgical management. Clinical outcome was good in all of Grade 1, and the surgical success rate was 83% in other groups. Our result suggests that surgical intervention should be considered for cases with more the severity of Grade 2.

    Of intracranial tumors, primary central nervous system lymphoma (PCNSL) is rare in dogs. Herein, we describe our experience with two dogs (a 3-year-old intact female toy poodle and a 5-year-old spayed female toy poodle) that developed neurological symptoms. Magnetic resonance imaging (MRI) revealed intracranial disseminated lesions. Cerebrospinal fluid (CSF) examination revealed pleocytosis and B-cell monoclonal proliferation in both cases. PCNSL or secondary central nervous system lymphoma (SCNSL) was diagnosed on the basis of MRI findings and CSF examinations. Nimustine (ACNU) is a nitrosourea alkylating agent, a class of drugs that includes lomustine. Nimustine is mainly used to treat human intracranial neoplasia because of its high permeability across the blood-brain barrier. The dogs in this study were treated with combined chemotherapy comprising nimustine and prednisolone, which achieved complete or nearly complete remission of neurological symptoms and long-term survival (>2583 days and 1218 days), but with problematic adverse effects. We determined that the dose of nimustine for canine PCNSL or SCNSL with intravenous infusion was 25–30 mg/m2 every 3–4 weeks for a total of four times; however, the data were insufficient to determine the optimal regimen.

    An eight-month-old, female Japanese Black calf weighing 213 kg showed bilateral hindlimb edema of unknown origin. The animal had no abnormalities in general condition and gait. As a result of a blood check, the presence of underlying diseases developing edema were not suspected. Clinical examinations and diagnostic treatments in this case eliminated systemic diseases including cardiac and nutritional disorders or regional inflammation and peripheral vascular disease as causes for the bilateral edema, but it was speculated to be due to a partial lymph flow disturbance. Lymphangiography was performed using an iodine based oily contrast medium, and the contrast medium was injected subcutaneously in the carpus and tarsus regions in both forelimbs and both hindlimbs. Sequential radiographs showed an inflow of the contrast medium into the lymphatics of both forelimbs, but not of both hindlimbs. Based on these findings, this calf was clinically diagnosed with lymphedema, and pathological examination confirmed the disease.

  • Usefulness of Computed Tomography for cryptorchidism in bulls Reviewed

    Cryptorchidism is defined as the failure of the testis to descend into the scrotal position. Bulls with cryptorchidism have problems in both meat quality and husbandry management; thus, it is greatly important to accurately identify the retained testis and remove it during the early stage. Abdominal computed tomography (CT) was performed under general anesthesia in 34 bulls aged 3–9 months with cryptorchidism. All bulls underwent laparoscopic or incision approach for cryptorchidectomy, and 40 testes were dissected. The detection rates of retained testes were 64.5% in the abdominal cavity and 100% in the subcutaneous inguinal region, and the total detection rate was 72.5%. Furthermore, all cases in this study were suspected to have intra-abdominal cryptorchidism in primary care, but CT revealed that 22.5% of cases had cryptorchidism in the subcutaneous inguinal region. The CT value (mean ± standard deviation) of the retained testes was 20.96 ± 7.54 Hounsfield Unit, and the CT value and size of the retained testes showed a positive weak correlation with bovine age. Therefore, there is the demerit that general anesthesia and a huge device are necessary; nevertheless, CT is suggested to be useful in identifying the location of retained testes and selecting an appropriate surgical approach in bulls with cryptorchidism. Moreover, CT findings suggested that the maturation of the retained testes might depend not on the descending process but on age.

    Introduction/objectives: In humans with impaired right-sided cardiac function, the caudal vena cava (CVC) diameter serves as a marker of venous congestion. This study aimed to investigate whether ultrasonographic CVC variables could identify the presence of right-sided congestive heart failure (R-CHF) in dogs with right-sided heart disease (RHD). Animals: Fifty client-owned control dogs and 67 dogs with RHD were enrolled. The dogs with RHD were subdivided into the non-R-CHF (n = 43) and R-CHF (n = 24) groups. Materials and methods: We measured and compared the ultrasonographic CVC variables and echocardiographic variables among the groups. Receiver operating characteristic (ROC) curve analysis was performed to calculate the sensitivity and specificity of the variables at optimal cutoff values. Results: We obtained the highest accuracies of the ratio of the shortest diameter (SD) of the minimal CVC area to the aorta diameter (Ao) during inspiration [SD(min)/Ao] and of the ratio of SD(min) to the longest diameter of the minimal CVC area during inspiration [LD(min),SD/LD(min)], with high sensitivities, specificities, and an area under the ROC curve greater than 0.925. Conclusions: In addition to the echocardiographic assessment of right-sided cardiac function, the CVC variables in this study, especially SD(min)/Ao and SD/LD(min), would be useful diagnostic indices for identifying R-CHF in dogs with RHD.

  • Repair of a calcaneal fracture with a combination of internal and external fixation in a calf

    A 6-day-old male Japanese Black calf presented with a transverse fracture of the left calcaneus. In calcaneal fractures, traction of the gastrocnemius muscle causes substantial displacement of the proximal fracture fragment; therefore, external fixation alone is prone to failure of fusion or deformed fusion. Furthermore, internal fixation alone may result in refracture due to the high load on the implant. Therefore, internal and external fixation were used to treat the fracture. Bone fusion was observed on postoperative day 50; the wire was removed on postoperative day 90. Radiographic examination at 4 months postoperatively revealed that the bone had fused in normal alignment. Therefore, a good prognosis can be expected for calcaneal fractures treated with combined internal and external fixation.
