  • Kyungokgo-gamibang, Kyungokgo with Iksuyongjingo and Sparassis crispa, is a traditional Korean medicine used for restorative effects. This study aimed to evaluate the safety of Kyungokgo-gamibang in healthy beagle dogs. In the single-dose oral toxicity study, three beagle dogs were orally administered 2,000, 1,000, and 500 mg/kg of Kyungokgo-gamibang and were observed for 14 days. In the repeated-dose oral toxicity study, nine healthy dogs were orally administered 0.2g/kg of Kyungokgo-gamibang (n = 3, low-dose group), 1 g/kg of Kyungokgo-gamibang (n = 3, high-dose group), or normal saline (n = 3, control group) twice a day for 8 weeks. The hematological, serum biochemical, urine, protein, and lipid profiles were evaluated to investigate the adverse effects of the Kyungokgo-gamibang. During the study period, the dogs demonstrated no clinical signs and the hematological, serum biochemical, urine, protein, and lipid analyses revealed unremarkable findings. The study results suggest that Kyungokgo-gamibang can be safely administered to dogs without any adverse effects.

  • Madecassoside, an active ingredient extracted from Centella asiatica, is used for treatment of various skin disorders in humans. However, the effect of madecassoside on the skin of dogs and cats has not been studied yet. The purpose of this study was to evaluate clinical efficacy of topical madecassoside cream in dogs and cats with skin diseases. A total of twenty-one dogs and ten cats with various skin diseases were included in the study. The 1% topical madecassoside cream was applied to the animal's skin lesion at least once a day for 7 days, and the skin condition was evaluated before the application of madecassoside cream (day 0) and 7 days after the application (day 7). The skin condition was scored by five clinical indices: canine atopic dermatitis extent and severity index-4 (CADESI-4), coat condition, pruritus, scale, and general condition. In dogs, all five clinical indices (CADESI-4, coat condition, pruritus, scale, and general condition) were significantly decreased on day 7 compared to those on day 0 (p < 0.0001, p < 0.05, p < 0.001, p < 0.01, and p < 0.05, respectively). In cats, the CADESI-4 and scale were significantly decreased on day 7 compared to those on day 0 (p < 0.01 and p < 0.05, respectively). No adverse effects were observed during the trial period in the dogs and cats included in this study. The results of this study demonstrate that the topical madecassoside cream is applicable to skin lesions in dogs and cats.

  • We describe the case of a Jindo dog that presented with a 2-month history of an abscess-like mass on the skin of the left hip. The patient was initially diagnosed with a suspected insect bite and was treated with a topical dressing. After observing no improvements, surgical debridement was done to remove the abscess. Nine days after surgery, the patient started showing severe anorexia, vomiting, lethargy, and oliguria. Azotemia was detected, and the patient was diagnosed with acute kidney injury. Ultrasonography depicted an abdominal mass (4.6 × 7.5 cm) in the right ureter, and severe hydronephrosis in the right kidney. The patient was euthanatized. Results of the necropsy, histopathologic examination, and immunohistochemistry for tumor cells, confirmed that the patient had developed hydronephrosis and disseminated histiocytic sarcoma which had metastasized to the lungs. To the best of our knowledge, this is the first report of acute renal failure produced by ureter invasion and urinary tract obstruction resulting from the abdominal mass of disseminated histiocytic sarcoma in dogs.

  • Avian haemosporidia, including malarial parasites, are geologically and biologically widespread. The protozoal pathogen has been a subject of intensive research in the past, which has resulted in major medical progress. Haemosporidia infection in avian species in South Korea has been studied in wild birds and layer flocks, but not in pet birds. At the Veterinary Teaching Hospital of Chungbuk National University, 75 birds that presented for health check-up were tested to evaluate the infection rate of Haemoproteus, Plasmodium and Leucocytozoon in birds without clinical symptoms. Haemoproteus spp. and Leucocytozoon spp. were simultaneously detected in a Major Mitchell's cockatoo (Lophochroa leadbeateri) by polymerase chain reaction, representing 1.33% of the tested birds. Phylogenetic analysis suggested that the infective Haemoproteus and Leucocytozoon strains were similar to those detected in foreign countries rather than those detected in the wild birds of Korea. Although the infection rate may not be indicative of a substantial infection in healthy pet parrots, the import of infected birds can pose a threat by allowing foreign pathogens to infect the local wild flocks or livestock. This is the first surveillance study of avian haemosporidia in pet parrots in South Korea.

  • Pet rabbits are affected by the highly contagious ectoparasite Psoroptes (P.) ovis, which carries significant economic implications for the global rabbit industry. Accurate identification of the mite species remains essential to implement effective treatment and control strategies. Two approximately one-year-old female pet rabbits were admitted to the Veterinary Teaching Hospital of Chungbuk National University due to excessive scratching of the ears and the presence of waxy debris within the ear canals. Mites were isolated from the waxy debris extracted from the ear canals and subsequently identified as Psoroptes spp. through microscopic examination. Species confirmation was achieved through mitochondrial cytochrome c oxidase subunit 1 (cox1) gene analysis. The analysis revealed the mites to be P. ovis based on cox1 gene sequences. The deposited GenBank accession numbers for these sequences are OR985022 and OR985023. This represents the first report of mitochondrial cox1 gene sequences of P. ovis isolated from pet rabbits in South Korea.

  • Context: There are no recent authoritative data about incidence and prevalence of various types of cancers in Pakistan. Aim: To determine the frequency of malignant tumors seen in our practice and provide a foundation for building a comprehensive cancer care strategy. Materials and Methods: 10,000 successive cases of solid malignant tumors reported in 2014 were included. All cases had formalin fixed, paraffin embedded specimens available and diagnosis was based on histological examination of H&E stained slides plus ancillary studies at the Section of Histopathology, Department of Pathology and Laboratory Medicine, Aga Khan University Hospital, Karachi. The latest WHO classifications were used along with the latest CAP protocols for reporting and the most updated TNM staging. Results: There were 9,492 (94.9%) primary tumors while 508 (5.1%) were metastatic. Some 5,153 (51.5%) were diagnosed in females and 4,847 (48.5%) in males. The commonest malignant tumors in females were breast (32%), esophagus (7%), lymphomas (6.8%), oral cavity (6.7%) and ovary (4.8%), while in males they were oral cavity (13.9%), lymphomas (12.8%), colorectum (7.9%), stomach (6.9%) and esophagus (6.6%). Malignant tumors were most common in the 5th, 6th and 7th decades. About 8% were seen under 20 years of age. Conclusions: Oral cavity and gastrointestinal cancers continue to be extremely common in both genders. Breast and esophageal cancers are prevalent in females. Lung and prostate cancer are less common than in the west. Ovarian cancer was very common but cervix cancer was less so.

  • Background: To evaluate the diagnostic utility of conventional ultrasonography and real time ultrasound elastography in differentiating degenerating cystic thyroid nodules mimicking malignancy from papillary thyroid carcinoma. Methods: We retrospectively analyzed conventional ultrasonographic and elastographic characteristics of 19 degenerating cystic thyroid nodules mimicking malignancy in 19 patients, with 30 surgically confirmed PTCs as controls. Based on size, the nodules had been grouped into less than 10mm (group A) and greater than 10 mm (group B). We evaluated conventional parameters and elasticity pattern. Color-scaled elastograms were graded as to stiffness of nodules using an elasticity pattern from I (soft) to IV (stiff). Results: Degenerating cystic thyroid nodules were similar to PTCs in conventional ultrasonographic findings, but the former frequently showed oval to round in shape (group A, 69.2% vs 18.8%, P=0.017; group B, 66.7% vs 7.14%, P=0.017) and punctuate hyperechoic foci (group A, 61.5% vs 0, P<0.001; group B, 50% vs 0, P<0.001). On real time ultrasound elastography, 7 of 13 degenerating cystic thyroid nodules in group A were pattern I, 5 were pattern II, 1 was pattern III. One degenerating cystic thyroid nodule in group B was pattern II, 5 were pattern III. The area under the curve for elastography was 0.98 in group A (sensitivity 92.3%, specificity 100%, P = 0.002), and 0.88 in group B (sensitivity 16.7%, specificity 100%, P = 0.014). Conclusions: As a dependable imaging technique, elastography helps increase the performance in differential diagnosis of degenerating cystic thyroid nodule and malignancy.
