Abstract : A 2-year-old intact female Maltese dog was presented with generalized involuntary tremors and nystagmus without regular direction. The dog was conscious the whole time while it was trembling. Its involuntary tremors were alleviated at rest or during sleep. Magnetic resonance imaging (MRI) revealed asymmetric hydrocephalus and caudal occipital malformation. In cerebrospinal fluid (CSF) analysis, a trace of protein was found and total nucleated cell count (TNCC) was slightly increased. However, infectious pathogens were not found. In complete blood count, there was a mild leukocytosis. After the patient received anticonvulsants (midazolam, phenobarbital, KBr), diuretics (furosemide) with an anti-inflammatory drug (prednisolone, 0.5 mg/kg PO bid), and a proton-pump inhibitor (omeprazole), it showed no improvement. The patient was tentatively diagnosed with corticosteroid responsive tremor syndrome. So the anticonvulsants and diuretics were discontinued and the dose of prednisolone was increased to an immunosuppressive dose (1 mg/kg PO bid). After administering the immunosuppressive dose of prednisolone, the patient did not show nystagmus. Its tremors were much alleviated. However, they did not disappear. Five weeks later, the patient showed gradual improvement but still was trembling when moving around. Nine weeks later, its tremors were similar to before. So diazepam (0.3 mg/kg PO sid) was added to the treatment. After that, its tremors were alleviated more. Prednisolone and diazepam were maintained for about five months, with tapering of the dose of prednisolone (until 0.5 mg/kg PO sid). About 7 months later after the treatment was started, the dog was trembling rarely except when it was excited. Therefore, diazepam was discontinued. This case describes a refractory white dog shaker syndrome successfully managed with long-term administration of a steroid and diazepam.

Abstract : Canine atopic dermatitis (CAD) is a genetically predisposed inflammatory and pruritic skin disease presenting characteristic clinical features in dogs. Despite oclacitinib and lokivetmab being commonly used, no study has compared their efficacies in CAD. This study aimed to compare the efficacy, safety, and control of CAD-associated pruritus and skin lesions between oclacitinib and lokivetmab. It also investigated whether switching to lokivetmab from oclacitinib or prednisolone had any benefits. Twenty-five client-owned dogs, newly diagnosed with CAD, were allocated to the oclacitinib (n = 20) and lokivetmab (n = 5) groups and administered oclacitinib (0.4-0.6 mg/kg orally, twice daily for 14 days, then once daily) and lokivetmab (2 mg/kg subcutaneously, every month) for 8 weeks, respectively. The switching group included five dogs previously administered with oclacitinib (n = 4) or prednisolone (n = 1) who were switched to lokivetmab directly at the start of the study. The pruritus visual analog scale (PVAS) and Canine Atopic Dermatitis Extent and Severity Index (CADESI-04) values were surveyed at weeks 0, 4, and 8. Oclacitinib and lokivetmab significantly reduced the PVAS and CADESI- 04 scores. Switching from oclacitinib or prednisolone to lokivetmab maintained the severity of pruritus (4 weeks: p = 0.068; 8 weeks: p = 0.068) and dermatitis (4 weeks: p = 0.144; 8 weeks: p = 0.068) at the levels measured at baseline. Thus, both oclacitinib and lokivetmab reduced CAD-associated pruritus by a similar degree. Switching to lokivetmab maintained the severity of pruritus and dermatitis at the same level as the previous treatment.

Abstract : A dog was presented with a cough, dyspnea, nasal discharge, gagging, and exercise intolerance. The dog showed leukocytosis, peripheral eosinophilia, and an increase C-reactive protein. The radiographic findings noted bronchointerstitial infiltration, intrathoracic lymphadenopathy, and soft tissue opacity mass. Computed tomography findings showed thickening of the bronchus and bronchiole. Also, peri-bronchial consolidation and generalized intrathoracic lymphadenopathy was present. On blind bronchoalveolar lavage and pulmonary cytology, there were significantly increased eosinophils. Canine pulmonary respiratory pathogens from a real-time polymerase chain reaction analysis was negative. Consequently, the dog was diagnosed with eosinophilic bronchopneumopathy. Clinical signs improved significantly within a few days after treatment with an oral corticosteroid.

Abstract : A seven-month-old castrated male Chihuahua weighing 1.6 kg presented with generalized tonic-clonic seizure following ingestion of isoniazid. Emergency treatment with three doses of diazepam (total 1.5 mg/kg, intravenous [IV]) and phenobarbital (15 mg/kg IV) was administered. The seizure stopped after administration of propofol (constant rate infusion [CRI]; 0.2 mg/kg/min). Blood analyses showed mildly increased serum blood glucose concentration, hyperkalemia, and hyperphosphatemia. On suspicion of isoniazid toxicity, activated charcoal (1 g/kg, orally), lipid emulsion (CRI; 9 mL/hr), and pyridoxine hydrochloride (70 mg/kg IV) were added to the treatment regimen. Twelve hours after presentation, the dog showed increased serum liver enzyme activities, serum blood urea nitrogen, and creatinine concentrations indicating hepatic and renal failure. Twenty-two hours after presentation, blood analysis still revealed increased liver enzyme activities, blood urea nitrogen, and creatinine concentrations with low blood glucose concentration. Twenty-six hours after presentation, the dog’s vital signs deteriorated and the owner elected for the dog to be euthanized. This is the first report of the clinical course of isoniazid toxicosis in a dog in South Korea. Furthermore, to our best knowledge, this is the first report where secondary multiple organ failure was observed due to isoniazid toxicosis. Clinicians should be aware of the possibility of isoniazid toxicosis in dogs. Rapid initiation of treatment after clinical recognition is warranted in such cases.

Abstract : This study was designed to investigate the characteristics of corneal ulcers in dogs with chronic kidney disease (CKD). Medical records of dogs that had been diagnosed with corneal ulcers and chronic kidney disease at Haemaru Referral Animal Hospital between April 1, 2011 and March 31, 2016 were investigated. A control group was randomly selected during the same time period. This group included patients with corneal ulcers but no evidence of systemic disease. The mean healing time of superficial corneal ulcers in the CKD group was 21.0 ± 15.0 days. This was a significantly longer healing time than was observed in the control group (11.0 ± 6.6 days, p = 0.019). The incidence rates of uveitis and keratoconjunctivitis sicca in the CKD group were significantly higher than in the control group (p = 0.000 and p = 0.026, respectively). Additionally, non-healing ulcers had significantly elevated white blood cell counts, while those with healing ulcers had WBC counts within the normal range in CKD group (p = 0.000). This study revealed that corneal ulcers in CKD patients would be delayed epithelial healing process and accompanied by ocular disease which affected to corneal healing compared to non-CKD patients.

Abstract : A 2-month-old intact female domestic short hair presented with physical abnormalities, including discharge of watery feces from the vagina, depression, and dehydration. The rectovaginal fistula and atresia ani type 3 were diagnosed on the vaginogram. During the anoplasty, the fistula could not be identified because the patient was too small. Instead of colotomy, feces were flushed out using a feeding tube. To prevent complications, a 1-cc syringe tip was sutured at the surgical site after the anoplasty. At the 3-month telephone follow-up after surgery, the cat was reported to have no further clinical signs.

Abstract : A 7-year-old intact male Maltese dog was presented with firm, raised, erythematous, alopecic, and pruritic skin lesions on the right dorsal distal metatarsal region and the tail. The skin lesion started a year ago with a crust-like lesion on the right dorsal distal metatarsal region which gradually swelled as the patient continued to lick and chew without healing. Recently, similar lesions occurred on the tail. Based on the licking history and ruling out other diseases through skin examination, acral lick dermatitis (ALD) was diagnosed. Treatment included antidepressants, preventive antibiotics, topical corticosteroid, and wearing Elizabethan collar as a physical barrier. After three weeks, the lesion on the hind limb healed entirely. However, the tail lesion recurred as it was able to lick the tail again with a type of an E-collar. This case shows that it is essential to block the contact lesion and provide medical treatment until the lesion has been completely resolved for successful management of ALD.

Abstract : A 10-year-old castrated male Shih-tzu dog presented with a history of generalized demodicosis, refractory to conventional therapy with ivermectin and amitraz for a year. The patient was also diagnosed with concurrent deep pyoderma, Malassezia dermatitis, and otitis externa. Treatment with amoxicillin-clavulanate, antifungal drugs (itraconazole, miconazole), and milbemycin oxime resulted in a good response for 90 days. Approximately 4 months later, the first relapse of demodicosis occurred and the miticidal therapy was changed to ivermectin. Additional diagnostic tests were performed to investigate an underlying cause for the recurrence of demodicosis, and endocrinopathies and allergic dermatitis were excluded based on the results. Although ivermectin therapy was sustained for 440 days, a second relapse occurred and amitraz baths were added to the therapy. Despite this therapy, the demodicosis persisted, and the miticidal therapy was changed to oral fluralaner, which led to rapid resolution. Demodicosis did not recur again before death approximately 920 days after administration of oral fluralaner. This case report describes the complete resolution of refractory demodicosis using oral fluralaner in a dog.

Abstract : 3-year-old spayed female beagle dog was presented with epiphora, severe hemorrhagic and purulent ocular discharge in the right eye (OD). A reflux of the discharge through the other canaliculi, associated with signs of chronic inflammation, was observed on cytology. Dacryocystorhinography revealed retention of contrast media ventral to the lower punctum, indicating complete obstruction and the potential presence of radiolucent foreign body. Ocular discharge subsided after the first treatment, including flushing of the nasolacrimal duct and application of topical antibiotics and corticosteroids, but clinical symptoms of the dacryocystitis waxed and waned thereafter. Surgical treatment was delayed for 8 months due to Dirofilaria immitis infection, and topical treatment and monthly flushing were maintained. On the day of operation, a foreign body was released through the fistula, while flushing for disinfection under general anesthesia, just before the surgery. Dacryocystectomy was performed to remove necrotic tissue and residual foreign body around the nasolacrimal cyst. Upon histopathologic findings, the removed foreign body was considered to be a plant, and the nasolacrimal cyst was comprised of chronic active ulcerative inflammation and necrotic tissues. At the 1-week recheck, improvement of epiphora and ocular discharge and healing of the surgical site was noted. In conclusion, nasolacrimal duct foreign body can be considered in recurrent dacryocystitis, despite nasolacrimal flushing and topical medication. In this study, dacryocystectomy was curative without recurrence of dacryocystitis or epiphora.

Abstract : A 14-month-old, intact female Maltese (case 1) and a 26-month-old, spayed female Dachshund (case 2) had persistent regurgitation over 1 year and 2 years, respectively. In both cases, there were not specific findings in blood examination. Diagnostic imaging and fluoroscopy revealed that gastroesophageal reflux (GER) occurred when the patients ate a barium meal without abdominal contraction. They were treated with proton-pump inhibitor (esomeprazole), sucralfate and prokinetics (cisapride) while in a standing position for an hour after every meal, according to the gastroesophageal disease (GERD) suggested treatment. The case 1 dog was discharged with improved clinical signs, and the case 2 dog also had been improved clinical signs; however, aspiration pneumonia occurred in case 2, which was thought to be a complication from GERD. After receiving treatment for aspiration pneumonia, the case 2 dog was discharged from the hospital. Since there was no further improvement in symptoms after discharge, the case 1 dog was euthanized by owner’s request, and the case 2 is alive, having only mild clinical signs upon the writing of this paper.
