A 13-year-old, 4.2 kg female poodle was referred for failure of first bilateral mandibular surgery at a local animal hospital after pathologic fracture. Surgery was performed with 2.0-mm miniplates/screws and porcine cancellous bone grafts. In addition, because of the large size of the right segmental defect, a barrier absorbable membrane was employed for guide bone regeneration on right mandible. After surgery, follow-ups performed at 1 day, 1, 4, 8, and 12 weeks; there were no signs of dental malocclusion, nonunion or soft tissue infection. However, a 1-year long-term follow-up showed nonunion in the left mandibular fracture site for which a collagen membrane had not been used. It is considered that use of porcine bone graft with barrier absorbable membrane may be effective for the repair of mandibular nonunion in a geriatric dog.

A 12-year-old female mixed Chihuahua dog was referred because of acute blindness and progressive tetraparesis. Mutifocal lesions in the cerebrum were noted on brain magnetic resonance images and cerebrospinal fluid analysis showed monocytic pleocytosis. Based on these results, granulomatous meningoencephalitis (GME) was strongly suspected. Cerebral lesions were definitely diagnosed as GME based on histopathological findings and positive results of immunohistological stains of brain with T-cell marker (CD3). This report describes the clinical findings, diagnostic imaging characteristics, and immunohistopathologic features of GME in an old dog. In addition, this case demonstrates that clinical signs of GME were mediated by perivascular infiltration of T lymphocytes and identification of causes in T cell-mediated inflammation should be further studied.

A 10-year-old intact female, mixed breed dog presented with abdominal distention of 2 months duration and three days of decreased appetite. The patient was conscious and no other gross abnormalities were noted. A tentative diagnosis of idiopathic massive hematoma or hemangiosarcoma was made on evaluating all clinical findings. Splenectomy was performed for treatment of abdominal distention and histopathological investigation was initiated to confirm the diagnosis. The hematoma was extremely massive on gross morphology, with the size of $20.2{\times}12.4cm$ and the splenic mass was diagnosed as hematoma formation, with moderate to marked lymphoid hyperplasia and adjacent moderate extramedullary hematopoiesis, based on microscopic description of spleen histology. This is the first case report in veterinary literature of a dog with extremely rare splenomegaly, an unusually large hematoma, with no malignancy or remarkable clinical signs.

관절와 병변은 급성 외상으로 인한 골절뿐 아니라 불안정성으로 인한 골 침윤으로 정의할 수 있으며, 이는 통상의 방사선학적 검사를 통하여 진단을 하지 못하는 경우도 있다. 전방 탈구와 동반된 전방 관절와 골절의 빈도는 5.4%에서 32%까지 보고되었다. Hovelius 등이 226명의 탈구환자를 대상으로한 연구에서 8%의 관절와 골절이 있었다고 보고하였고, 노령의 환자에서 약간의 빈도가 증가한다고 하였다. 또한 Rowe는 전방 관절와 골절이 있는 27명의 환자에서 기계적 안정성의 결함으로 62%의 재발성 탈구가 있었다고 보고하였다. 보다 최근의 방카르트 술기에 대한 보고에서 수술적 처치를 한 환자중 44%가 관절와 골절을 동반하였다고 보고하였다. Rowe 와 Zarins는 다발성 전방탈구 환자에서 관절와 병변이 잘 치료되었는지 여부에 따라 다른 결과를 낸다고 보고하였다. 전자에 따르면, 관절와 병변을 진단하는 것은 중요하며 환자의 최종적 예후는 이를 어떻게 치료했는지 여부에 따라 결정된다고 하였다. 관절와 상완관절의 불안정성에서 동반된 관절와 병변의 진단은 보존적 치료시나 수술적 치료 시 모두 중요한 인자라고 하겠다.

A 12-year-old spayed female, Golden Retriever presented with dyspnea and lethargy of 3 months duration. Pericardial effusion and cardiac mass were identified on echocardiography. Pericardiectomy and mass resection were performed for treatment of pericardial effusion and histopathological analysis was conducted for the definitive diagnosis. The mass was diagnosed as hematoma with mainly erythrocyte, fibrin and many of neutrophils based on microscopic description. Severe purulent pericarditis thickened by inflammatory cells and reactive fibrous tissue were identified, but not diagnosed as neoplasm. This is the first case report in veterinary literature of a dog with pericardial effusion caused by cardiac hematoma.

Purpose: The purpose of this study was to evaluate the tendon healing of arthroscopic repair in full-thickness supraspinatus tears. We evaluate the effectiveness of the arthroscopic repair of full-thickness supraspinatus tears by assessing functional improvement. Materials and Methods: Thirty consecutive full-thickness supraspinatus tears were repaired arthroscopically in 19 patients with a one row of anchor and 11 patients with two rows of anchors. Patients ranged in age from 51 to 79 years (average 63 years). Average follow-up was 16 month (range, 12 to 28 months). To evaluate the effectiveness of the arthroscopic repair of full-thickness supraspinatus tears by assessing functional improvement, we calculate the Constant, ASES, UCLA scores. The 30 patients had either an MR Arthrogram (25 cases) or an MRI (5 cases), performed between 5 months and 20 months (mean 10 months) after surgery. Results: The cuff was healed in 21/30 cases (70%) and partially torn in 3 cases (10%) after the arthroscopic repair of full-thickness supraspinatus tear. Although the supraspinatus tendon was totally torn to the tuberosity in 6 cases(20%) after the arthroscopic repair, the size of the tear was smaller than the initial in 5 cases. The Constant score improved from an average of $55.7{\pm}7.1$ points preoperatively to $77.7{\pm}9.7$ points at the last follow-up (p<0.001), and the average ASES score improved from $39.2{\pm}7.4\;to\;72.4{\pm}12.6$ (p<0.001), and the average UCLA score improved from $17.9{\pm}2.2\;to\;26.8{\pm}5.0$ (p<0.001). Strength of elevation was significantly better $(7.1kgs{\pm}2.4)$ in the shoulders with a healed tendon that in those with an total or partial re-tear tendon $(4.5kgs{\pm}1.0)$ (p<0.05). Factors adversely affecting tendon healing were increasing age, Only 41.7% of the repairs completely healed in patients over 65 years (p<0.05). Conclusion: Arthroscopic repair of isolated full-thickness tear of the supraspinatus leads to completely healing in 70% of the cases. Total or partial re-tear of the repaired rotator cuff is associated with a decreased strength. Older patients had significantly lower healing rates.
