We present a case of an intact 14-year-old male dog with a prostate B-cell lymphoma recognized in the contents of an irreducible perineal hernia. The enlarged prostate was replaced after reducing its size by partial excision, and the perineal hernia was repaired using the tunica vaginalis communis. However, the pelvic cavity was largely occupied by the replaced prostate, and urinary retention developed. The prostate was resected on the next day via abdominal median incision, and a bladder-urethra anastomosis was performed. Lymphoma has rarely been demonstrated to develop in the prostate, with the lesion comprising the hernia contents. The present study suggests the necessity of early treatment for perineal hernias and the possibility that lymphoma may be present in the hernia contents.

Appropriate dosages of cilostazol have not been studied in veterinary patients, and the degrees of heart rate (HR) increase have not been studied in dogs administered cilostazol. Therefore, this study aimed to investigate the degrees of HR increase in healthy dogs administered cilostazol. Thirty healthy beagle dogs (15 males and 15 females; age, 5–8 years) were divided into 3 groups of 10 dogs each and orally administered 2.5, 5, or 10 mg/kg cilostazol (twice a day at 8:00 AM and 8:00 PM for 10 days). Higher HR increases were seen in the 5 mg/kg group than in the 2.5 mg/kg group at all time points except 7:00 AM, 9:00 AM, 1:00 PM, and 4:00 PM (P<0.01). Higher HR increases were also observed in the 10 mg/kg group than in the 2.5 mg/kg group at all time points except 4:00 PM (P<0.01). The 10 mg/kg group showed higher HR increases than the 5 mg/kg group at all time points except 6:00 AM, 7:00 AM, 6:00 PM, and 7:00 PM (P<0.05 for 4:00 PM and 5:00 PM; P<0.01 for the other time points). These results together show that the HR of healthy dogs increased in a dose-dependent manner after cilostazol administration twice a day at doses of 5 to 10 mg/kg. These results provide a useful basis for choosing cilostazol in the treatment of bradyarrhythmia in dogs.

A 7-year-old Miniature Schnauzer presented with exercise intolerance and easy fatigability. Echocardiography revealed the presence of supravalvular pulmonary stenosis. The peak velocity through the stenosis was 6.4 m/sec, and the interventricular septum was flattened. Cutting balloon angioplasty was designed for the treatment of coronary artery stenosis, which was resistant to conventional balloon angioplasty. Accordingly, the dog underwent cutting balloon angioplasty and conventional balloon dilation. One month after treatment, it showed neither exercise intolerance nor easy fatigability. The ventricular septum flattening disappeared. Five months later, the dog showed an increase in activity. Two years later, the peak velocity through the stenosis decreased to 4.4 m/sec. Neither clinical symptoms nor restenosis was observed. Thus, supravalvular pulmonary stenosis was successfully treated using this combination method. The present case showed that combined cutting balloon and conventional balloon angioplasty is a useful and minimally invasive treatment for supravalvular pulmonary stenosis.

Laparoscopic cholecystectomy (LC) is widely accepted as the standard treatment for benign gall bladder diseases in humans because it has proven to be less invasive and safer than are traditional methods. However, the efficacy of LC in dogs remains unclear. The present study aimed to examine the short-term outcome of LC for benign gall bladder diseases in dogs. We enrolled 76 consecutive dogs that underwent LC for benign gall bladder diseases at our hospital between April 2008 and October 2016. Dogs with jaundice, gall bladder ruptures, abdominal effusion, or extrahepatic biliary obstruction were not excluded from the indication. Factors including age, body weight, sex, clinical sign, disease, operative time, conversion to open surgery, perioperative complications, and postoperative hospital stay were investigated. The median age of the dogs was 11 years, and the median body weight was 5.4 kg. Fifty percent of the dogs exhibited no symptoms at the initial visit. Preoperative elevation of total bilirubin levels was observed in 16 dogs (21%). LC was successfully completed in 71 dogs (93%); the median operative time was 124 min. Although gall bladder ruptures were observed in 2 (2.6%) dogs, the operations were completed successfully. Three dogs (4.1%) had to be converted to open cholecystectomy and 2 (2.6%) underwent reoperation. Two dogs (2.6%) died intraoperatively and 2 (2.6%) died postoperatively. LC was a feasible, safe, and appropriate procedure considering the current operative indications for benign gall bladder diseases in dogs.

The neoplastic mass developed in the left flank of a Border Collie dog. The tumor was resected surgically and evaluated histologically and immunohistochemically. Histologically a moderate number of spindle cells were proliferated with staghorn, placentoid, and myxoid growth patterns and a lack of perivascular whirling. Immunohistochemically, the tumor cells were positive to vimentin, laminin, S-100 protein, CD34 and CD117 antibodies. They were negative to cytokeratin AE1/3, desmin, α-SMA and calponin antibodies. Endothelial cells of the staghorn channels were positive for vWF antibody. The present case was diagnosed as spindle cell tumor, but it was similar to human classical hemangiopericytoma (HEP) and canine HEP classified by Avallon and others.

The right third eyelid of an adult female brown bear (Ursus arctos) was swollen and removed. Histopathology revealed a tumor exhibiting proliferation with mild infiltration, consisting of multi-stratified glandular structures of the innermost laminal neoplastic cells and the basaloid neoplastic cells, and with eosinophilic thick basal lamina material around the glandular structures. Both types of neoplastic cells exhibited moderate anisokaryosis, and mitotic figures were observed in the basaloid neoplastic cells. The laminal neoplastic cells were cytokeratin (CK) 8/18-positive. In contrast, the basaloid neoplastic cells were CK14- and p63-positive, but α-smooth muscle actin- and calponin-negative. The case described herein is the first report of basal cell adenocarcinoma in the gland of the third eyelid of a bear.

A one-year-old male Golden Retriever presented with acute onset of vomiting and hemorrhagic diarrhea since 2 days. The dog was depressed, showing abdominal pain, 12% dehydration, tachycardia, and a bounding pulse. Diagnostic imaging showed severe dilatation and fluid retention of the entire gastrointestinal tract with decreased motility. A foreign body was found in the gastroduodenal region, but there was no obstruction or plication. The dog was tentatively diagnosed with acute hemorrhagic diarrhea syndrome and rapidly recovered after supportive treatment. However, on the morning of day 4, anorexia and vomiting recurred, and diagnostic imaging revealed intestinal plication with free peritoneal fluid, not found on the previous image. An emergency laparotomy revealed the foreign body to be two used feminine hygiene products. These contaminated products were suspected to induce acute hemorrhagic diarrhea syndrome, and led to subsequent complication in this large dog.

This study reports on two Hanwoo (a native Korean breed of cattle) calves, a 3- and 6-month-old presenting with diarrhea, anorexia and blindness. Ophthalmoscopic examination revealed bilateral papilledema in both calves. Reverse-transcription polymerase chain reaction tests for bovine viral diarrhea virus, rotavirus and coronavirus were all negative. The levels of serum vitamin A in the two affected calves were 0.317 µg/dl and 0.481 µg/dl, respectively. These values are much lower than the normal vitamin A levels; therefore, the calves were diagnosed with hypovitaminosis A.

A 14-month-old Japanese black beef steer presented with severe chronic diarrhea and emaciation and was euthanized. Postmortem examination showed thickened and corrugated intestinal mucosa and enlarged granulomatous mesenteric lymph nodes with caseating necrosis. Numerous epithelioid cells and multinucleated giant cells infiltrated in the lamina propria and the submucosal tissue of the intestines. These cells were also observed in the systemic organs. Many acid-fast bacilli were detected in the cytoplasm of these cells and were identified as ‘Mycobacterium avium subsp. hominissuis’ (Mah) on the basis of the results of molecular examinations and immunohistochemistry. These findings indicate that Mah can cause systemic mycobacteriosis, and this unique infection needs to be distinguished from Johne’s disease and tuberculosis in cattle.

A 16-year-old castrated male mongrel cat presented with swelling under the left pinna and a 3 -month history of voice change. Laryngeal endoscopy revealed circumferential oedema around the arytenoid cartilages and hypersecretion of saliva. Histopathological examination of the mass around the left ear canal was considered the primary lesion that originated from cutaneous apocrine adenocarcinoma or parotid gland adenocarcinoma, and it metastasized to the larynx, lung and medial retropharyngeal lymph nodes. This report provides new insights into feline laryngeal diseases which could result in laryngeal metastasis with slight mucosal irregularity alone and without obvious radiographic abnormalities. Therefore, histopathological examination should be performed when a cat presents clinical signs such as stridor, dysphonia or voice change without any mass-forming laryngeal lesion.

In cases of food poisoning, it is important for food sanitation inspectors to determine the causative pathogen as early as possible and take necessary measures to minimize outbreaks. Interviews are usually conducted to obtain epidemiological information to aid in the rapid determination of the cause. However, the current method of determining the causative pathogen has the disadvantage of being reliant upon the experience and knowledge of food sanitation inspectors. Here, we analyzed 529 infectious food poisoning incidents reported in five municipalities in the Kinki region to develop a tool for evaluation using a multinomial logistic regression model, which can predict the causative pathogen based on the patients’ epidemiological information. This tool predicts the most probable cause of the incident by generating a list of pathogens with the highest probability. As a result of leave-one-out cross validation, the agreement ratio with the actual pathogen was 86.4%, and this ratio increased to 97.5% when the agreement was judged by including the true pathogen within the top three pathogens with the highest probability. In cases where the difference of probability between the first and second candidate pathogen was ≥50%, the agreement ratio increased to 94.2%. Using this tool, it is possible to accurately estimate the causative pathogen at an early stage based on patient information, and this will further help narrow the target of investigations to identify causative agent, thereby leading to a prompt identification, which can prevent the spread of food poisoning.

The purpose of this study was to determine the relationships among body condition score (BCS), radiography, and computed tomography (CT), and to establish a method for body fat assessment on CT in dogs. 38 Beagles with 2 to 7 BCS were examined. Subcutaneous fat thickness on radiograph (ST) and body area (BA), total fat area (TA), subcutaneous fat area (SA), and visceral fat area (VA) on CT were measured at the level of L3 and L6 vertebra. Ratios of each value to the L6 length were obtained (rST, rTA, rSA, rVA) and the correlations with BCS were estimated. The value of VA/SA, VA/TA, TA/BA, VA/BA, and SA/BA were selected for measuring fat and the correlations with BCS were estimated. The rST, rTA, rSA, and rVA were significantly correlated with BCS, and the rTA and rSA were significantly correlated with rST. At the level of L3, rTA and rVA had stronger relationships with BCS than at L6 while rSA had a higher correlation with BCS at L6. TheTA/BA, VA/BA, and SA/BA were significantly correlated with BCS, and the upper limits were 15.11%, 6.31%, and 8.92%, respectively. Our results showed that CT could be useful to assess body fat and TA/BA, VA/BA, and SA/BA are suitable criteria for measuring fat on CT. In addition, L3 was a more suitable location for evaluating total and visceral fat, and L6 was more suitable for evaluating subcutaneous fat.

Robenacoxib is a novel nonsteroidal anti-inflammatory drug approved for dogs. The present study aimed to evaluate influences of sevoflurane anesthesia on the distribution of robenacoxib in dogs. Ten healthy beagle dogs (1 to 11 years old, 9.3 to 14.3 kg body weight, 6 males and 4 females) were subcutaneously administered robenacoxib (2 mg/kg) under conscious condition or sevoflurane anesthesia inhaled a 1.3-fold predetermined individual minimum alveolar concentration of sevoflurane at a 28-day interval. The dogs under sevoflurane anesthesia were also mechanically ventilated and received fluid-therapy. On each occasion, serum samples were collected from the dogs before and at 5, 15, 30, 60, 120, 180 and 240 min after the robenacoxib administration. Serum robenacoxib concentration was measured by a liquid chromatography-tandem mass spectrometry. Maximum serum concentration of robenacoxib (Cmax) was 2.2 μg/ml [range: 1.2–4.6] (median [range: minimum–maximum]) and time of Cmax (Tmax) was 90 min [range: 60–120] in the conscious dogs. In the sevoflurane-anesthetized dogs, the Cmax significantly declined (1.3 μg/ml [range: 0.8–1.4], P=0.008) and Tmax was delayed (120 min [range: 120–240], P=0.018) compared with those in the conscious dogs. The serum robenacoxib concentration at 240 min (C240) decreased to 0.5 μg/ml [range: 0.2–0.9] in the conscious dogs, while it remained higher in the sevoflurane-anesthetized dogs (1.0 μg/ml [range: 0.3–1.4], P=0.011). In conclusion, the anesthetic procedure with sevoflurane, mechanically ventilated, and received fluid-therapy might affect the pharmacokinetics of subcutaneously administered robenacoxib in dogs.

We surveyed the kidneys of dogs with immune-complex mediated glomerulonephritis (ICGN) by lectin histochemistry using seven lectins—namely WGA, RCA-I, ConA, PNA, SBA, DBA, and UEA-I. Their binding patterns were compared with those from normal dogs. RCA-I signals became weak in the brush borders of the proximal tubules, whereas DBA signals became positive in Bowman’s capsules. Also, varying intensity of the UEA-I signal was noted in the distal tubules, especially in the macula densa. The binding pattern profiles varied among the cases; this diversity in the lectin-binding patterns might be induced as a result of the diverse pathologies seen in canine ICGN.

Pneumatosis coli is a rare intestinal disorder in dogs that is characterized by submucosal or subserosal emphysema of the colon. An 8-year-old castrated male Shih Tzu developed anorexia and hematochezia after undergoing surgery for a congenital splenophrenic shunt. Abdominal radiographic examination revealed linear radiolucency throughout the wall of the large intestine. Results of abdominal computed tomography revealed intramural gas tracking along the colon and rectum. Based on these findings, a diagnosis of pneumatosis coli was made. The dog was treated with antibiotics, but the general condition gradually deteriorated, and the dog died 6 days after the day of diagnosis. It was suspected that portal hypertension following partial ligation of congenital portosystemic shunt may have been associated with pneumatosis coli in this case.

Although chondroinductive growth factors are considered necessary for chondrogenesis of bone marrow-derived mesenchymal stem cells (BMSC), independent and spontaneous chondrogenesis has been previously demonstrated in adult horses, bovine calves and adult human BMSC. Surprisingly, adult canine BMSC under similar culture conditions previously failed to demonstrate chondrogenesis. The present study evaluated independent chondrogenic potential of BMSC sourced from three young dogs in the absence of known chondroinductive factors. BMSC were culture expanded in 10% DMEM up to third passage (P3). At each passage, the phenotype of BMSC was evaluated by RT-PCR gel electrophoresis and qPCR. BMSC exhibited a chondrogenic phenotype in the absence of dexamethasone and TGF-β1 as verified by the expression of Sox-9, type II collagen and aggrecan. Sox-9 was significantly downregulated (P<0.05) from P1–P3 compared to P0 while type II and X collagen, and aggrecan were significantly downregulated at P3 compared to P0. There was a significant (P<0.01) negative correlation between passaging and Sox-9, type II collagen and aggrecan gene expression. These results indicate that independent chondrogenic potential and phenotype retention of BMSC decreases in a passage-dependent pattern. Therefore, caution should be exercised for future experiments evaluating the chondrogenic potential of BMSC after extensive expansion cultures in 10% DMEM.

Canine distemper virus (CDV) is an infectious agent that can cause canine distemper (CD), a lethal disease. Immunization is an effective method to control the infection; however, some cases of failed immunization are observed in animal hospitals every year. Therefore, in this study, we conducted phylogenetic analysis of the H gene of isolated CDVs. We first constructed a modified MDCK cell line, which constitutively expressed signaling lymphocyte activation molecule (SLAM), a specific receptor for CDV. The modified cell line was more suitable for propagation of CDV than the original MDCK cell line. Next, 9 CDVs were successfully isolated from 20 dogs with suspected CD-associated diseases. Of these CDV isolates, three were from vaccinated dogs. The analysis indicated that the H gene sequences of these 9 viruses were highly similar. The present study further supported the finding that the majority of CDV in China belonged to the genotype Asia-1, which was different from vaccine strains (America-1 and America-2). Although the clinical application of the vaccine suggested that it is effective against CDV infection, it remains an open question whether a novel vaccine based on the genotype of the Asia-1 strain would be more suitable for protection of dogs against Asia-1 CDVs infection.

A large abdominal mass was found in a dog. Histopathologically, the surface of the mass was covered with compressed adrenal gland tissue. The neoplastic cells showed typical features of malignant peripheral nerve sheath tumor (MPNST), including Antoni type A and type B pattern, and nuclear palisading. Immunohistochemically, these cells were positive for S100 protein, nerve growth factor receptor, nestin and claudin-1. The dog was euthanized because of the developing multiple metastatic lesions. The metastatic cells showed quite similar histopathological and immunohistochemical features as those in the original tumor. Although MPNST can develop at many body sites, this is the first report of MPNST originating from the adrenal gland in a dog.
