This study was performed to investigate the wound healing effects of Allium cepa L. on Staphylococcus intermedius contaminated wound. 4 full-thickness skin wounds ($2\;cm{\times}2\;cm$) were made in the back and Staphylococcus intermedius was inoculated in seven dogs. In each dog, the wounds were treated with onion extract (experimental group) and normal saline (control group), respectively. The wound contraction rate of the experimental group was higher than that of the control group during the experimental period. The occupation rate showed that the wounds of the experimental groups contracted more vigorously than that of the control group in the early period of wound healing. The mean value of tensile strength on the 22 day after wounding was $4,741{\pm}848\;g/cm^2$ in the experimental group and $2,400{\pm}397\;g/cm^2$ in the control group. The number of S. intermedius in the experimental groups was decreased more rapidly than that of the control group. These results suggest that application of activated onion extract in like full-thickness skin wounds promote wound healing.

A 13-year-old spayed female American cocker spaniel dog was submitted to an animal hospital with a mass from left ear canal and enlarged left parotid lymph node. Given one-year history of odorous exudates and chronic otitis externa, total ear canal ablation was performed. Grossly, because of the neoplastic mass in both inner and outside of annular cartilage in external ear, vertical ear canal was severely narrowed. Histologically, there were numerous proliferated glands in the ear canal mass. Many neoplastic glands contained secretory vesicles on the free margin and necrotic cellular debris. Severe multifocal necrosis and strong invasion were also observed throughout the mass. Massive metastatic foci of glandular structures originated from ceruminous gland were presented in the enlarged parotid lymph node. Neoplastic glandular epithelia contained PAS-positive diastase-resistant eosinophilic cytoplasmic granules. Immunohistochemically, the neoplastic cells showed positive reactions for cytokeratin (CK) 7 and negative for CK 5/6. Based on the clinical implication and gross findings, histopathology and immunohistochemistry, this case was diagnosed as metastatic ceruminous gland adenocarcinoma in the American cocker spaniel.

Three 8-12-year-old male cocker spaniels presented with an appendicular mass accompanied by pain, inflammation, lameness, and loss of nail in the digits of the forelimb or hindlimb. A histological examination revealed dermal masses of the digit composed of numerous neoplastic cells with marked pleomorphism and high mitosis. The neoplastic cells showed a strong invasive tendency into the epidermis and adjacent bony tissues, such as distal phalanx. Immunohistochemistry of the neoplastic cells in three masses revealed positive reactions for Melan-A. These three dogs were diagnosed as nailbed malignant melanoma in the digit based on the history, clinical signs, and histopathologic features.

This retrospective study is designed to compare the clinical results of tibial tuberosity transposition (TTT) and anti-rotation suture (ARS) treatments for medial patellar luxation (MPL). Medical records of 133 dogs were reviewed that had undergone surgical correction of MPL between January 2013 and May 2017. MPL correction was performed on 182 stifles, with TTT and ARS being performed on 101 stifles and 81 stifles. The common dog breeds receiving surgical treatment for MPL were Maltese, Pomeranian, Chihuahua and Poodle. Mean age of dogs with MPL was 32.6 months, and their mean body weight was 4.26 kg. Seventy dogs (52.6%) were male and 63 (47.4%) were female. Of the 182 stifles with MPL, grade II, III and IV were 18.7%, 72.0% and 9.3%. Total complications after TTT and ARS were recorded in 16.8% and 29.6%. Major complications after TTT and ARS were recorded in 5.9% and 12.3%, minor complications after TTT and ARS were recorded in 10.9% and 17.3%. The risk of complication and reluxation rate after TTT were significantly lower than that for ARS (p < 0.05). However, the rate of reluxation among dogs treated by ARS (1.2%) for grade II MPL was significantly lower than that for dogs treated by ARS (8.6%) for grade III MPL (p < 0.05). The TTT group had a shorter recovery period after surgical intervention than that in the ARS group (p < 0.001). In conclusion, TTT had a significantly lower incidence of complication and a shorter recovery period than ARS. However, ARS for grade II MPL appears to be a good surgical option for reducing the rate of reluxation after surgery. These results of this study could be used to provide therapeutic guidelines for surgical MPL correction in small-breed dogs.

체중 2.7 kg의 5세령 암컷 말티즈 견이 양측 슬개골 탈구와 후지 파행으로 지역동물병원에 내원하였다. 도르레절제술과 슬개골의 외측 보강 봉합법을 이용하여 슬개골 탈구 정복술을 실시하였으나, 수술 3주 후 등을 굽힌 자세의 보행과 후지의 운동실조, 흉요추부의 압통, 간헐적인 경련증상으로 재 내원하였다. 자기공명영상 촬영 결과, 우측 전두엽의 종괴와 경수에서부터 3번 요수까지의 공동성 변화가 확인되었다. 병리조직학적 소견으로 뇌종양은 느슨한 망상구조 또는 레이스 모양의 수막세포들로 구성되었으며, 세포 외부에 다양한 크기와 형태의 많은 낭포성 공간이 관찰되었다. 면역조직화학염색 결과 종양세포들은 vimentin 양성, 신경원 특이 에놀라제 및 신경교 섬유질 산성 단백질에는 음성을 나타내었다. 경수와 흉수 부위에는 부정형의 확장된 중심관 유사 동공이 관찰되었다. 이 증례는 개에서 특이적인 두개강 내 소낭성 뇌수막종과 연관되어 2차적으로 발생한 척수공동증의 임상소견과 영상학적 및 병리조직학적 특징을 보여주고 있다.

Wii^® balance board (WBB, Nintendo, Japan) is a device that can measure and record the center of pressure path length (CPPL) and 95% confidence ellipse area (Area 95) in relation to body sway. For evaluating measure of improvement after reconstruction of medial patellar luxation (MPL) in small sized dogs, A total of 6 dogs with limping and lameness gait attributed to Grade II, III or IV MPL were evaluated. Dogs were measured for difference of extension and flexion range of motion in the stifle (dROM), muscle mass, lameness, willingness to bear weight on the affected limb while standing, and willingness to lift the contralateral limb scores, CPPL and Area 95 of WBB on pre-surgery, post-surgery 4, 8 weeks. CPPL was significantly different on pre-surgery compared with post-surgery 8 weeks (p < 0.05). Except for CPPL, measured variables were significantly different on pre-surgery compared with post-surgery 4 and post-surgery 8 weeks (p < 0.01).

A 6-year-old female Boston terrier dog was presented with seizure episode, forelimb paraparesis, excessive panting, and ataxia. On physical and neurological examination, episcleral vessel engorgement, delayed postural reaction, delayed pupillary light reflex (both direct and consensual), and crossed forelimb were noted. Serum biochemical profiles were not remarkable other than mildly elevated hepatic enzymes. On cerebrospinal fluid analysis, elevated protein concentration was observed. In magnetic resonance imaging scans, the left frontal brain lesion with ring enhancement strongly suggested the presence of intracranial tumor. Concurrently, secondary hydrocephalus and syringomyelia were also observed. The dog was euthanized at 4 months after initial presentation because of aggravated neurological signs. This case was definitely diagnosed as an intracranial anaplastic oligodendroglioma based on postmortem histopathologic examination.

An adult female dog was presented for evaluation of mammary gland masses. Complete blood count and serum chemistry data were within normal limits. Fine-needle aspiration cytology of the mammary masses revealed clusters of malignant epithelial cells with clear cytoplasmic vacuoles. Based on histopathological findings, a diagnosis of lipid-rich mammary carcinoma was made. Approximately 5 weeks after surgical removal, the tumor recurred at the surgery site and metastasis to the tibia was detected. Due to the poor prognosis and deterioration of the condition, the dog was euthanized.

A 10-year-old spayed female Cocker spaniel weighing 6.64 kg was presented with a sign of syncope. Electrocardiographic findings revealed pathologic atrioventricular (AV) block alternating 3rd degree AV block, non-responsive to atropine. Before pacemaker implantation, several anti-hypertensive medications were administered, but there was no improvement. After pacemaker implantation, the heart rate and systemic arterial systolic blood pressure were immediately improved. This is the first report on the resolution of an AV block and malignant systemic hypertension after a pacemaker implant in veterinary medicine.

9세령의 수컷 도베르만견이 5개월간 간헐적인 혈뇨, 구토 및 당뇨증상을 보여 동물병원에 내원하였다. 초음파상에서 종대된 좌측 신장의 수질부위에 종괴가 발견되었다. 육안적으로 좌측 신장의 피질 및 수질부는 현저하게 위축되어 있었으며 신우 부위는 종괴로 인하여 확장된 수신증을 나타내었다. 크기 4~5.5 cm의 유두상으로 돌출된 꽃자루와 같은 단일종괴가 신우 부위에 있으며, 요관으로 뻗어 있었다. 병리조직학적으로 종괴는 나뭇가지 모양으로 무수히 돌출된 유두상의 돌기들로 구성되어 있었다. 이 돌기들은 섬유혈관성 중심부와 뚜렷한 이형태성을 가지는 여러 층의 종양화된 이행상피들로 피복되어 있었다. 면역조직화학염색을 실시한 결과 종양세포들은 사이토케라틴(cytokeratin: CK) 7, 19, CK clone MNF116 및 CK HMW에 대해서 양성을 보였으나 CK 8 LMW에서는 음성 반응을 나타내었다. 육안적인 특징, 병리조직학적 소견 및 면역조직화학염색에 의한 사이토케라틴의 반응성을 토대로 이 종괴는 개의 신우에서 발생한 이행상피암종으로 진단되었다.
