OBJECTIVE: To determine the prevalence of each risk category for diabetic foot ulcer by foot screening test with Semmes-Weinstein monofilament and to evaluate the correlation of the risk category with clinical data in diabetic inpatients. METHOD: Foot screening tests with Semmes-Weinstein monofilament was performed in 90 diabetic inpatients to determined the risk category for diabetic foot ulcer. An average age of patients was 55 years, and an average duration of the disease was 11 years. The correlation of risk category was evaluated with age, duration of the disease, FBS (fasting blood glucose) level, HbA1c value, and complications of diabetes including retinopathy, peripheral polyneuropathy, and renal failure. RESULTS: Patients with risk category 0 had no loss of protective sensation in 34.4% of cases. Patients with risk category 1, 2, and 3 had loss of protective sensation in 16.7%, 28.9% and 20% of cases, respectively. The older a patient was and the longer the duration of the disease was, the higher the risk category was significantly (p<0.05). There was no significant correlation of risk category with FBS level and HbA1c value. Among the complications associated with diabetes, retinopathy and peripheral polyneuropathy significantly correlated with risk category (p<0.05), but renal failure was not significantly associated. CONCLUSION: The foot screening test with Semmes-Weinstein monofilament should be helpful for proper management of diabetic foot in inpatient.

Canine parvovirus type-2 (CPV-2) is one of the major diarrhea-causing agents, inducing acute hemorrhagic gastroenteritis in puppies. In this study, we conducted a seroepidemiological survey of CPV-2a in stray dogs in South Korea. In total, 405 canine sera, collected between 2006 and 2007, were screened for the presence of antibodies against CPV-2a using a hemagglutination inhibition (HI) assay. The positive rate in stray dogs tested for CPV-2a was 93.8%. The regional CPV-2a prevalence was 100% (8/8) in Jeju, 95.1% (232/244) in Gyeonggi, 94.7% (36/38) in Jeonra, 92.9% (13/14) in Gangwon, 92.7% (38/41) in Chungcheong, and 88.3% (53/60) in Gyeungsang province. No significant difference in the seropositive rate was found between male (93.6%) and female (94.0%) dogs. Analysis of the distribution of HI titer against CPV-2a according to the age of the stray dogs showed a linear increase in seroprevalence with age, although the association with age was not statistically significant. The incidence of stray dogs showing an HI antibody titer above 1:5120 was estimated to be 26.2%. Thus, the presence of high HI antibody against CPV-2a may indicate circulation of CPV-2a in stray dogs.

OBJECTIVES: The aim of this study was to retrospectively evaluate the clinical survival rate of Astra Tech implants in the maxillary molar region performed with sinus lift and bone graft. MATERIALS AND METHODS: Ninety-nine Astra Tech implants (Osseospeed) placed in the maxillary molar region using sinus lift from September 2009 to February 2012 were selected with a minimum follow-up period of 1 year. The height of alveolar bone, sinus approach technique, bone material and implant survival rate were evaluated. RESULTS: Of the 99 implants, the survival rate was 90.9%; 8 implants failed within 1 year after implant placement, and 1 implant failed 1 year after implant loading. All failed implants were placed with sinus lift simultaneously. The average height of alveolar bone before implant placement was 6.9 mm, while the height of alveolar bone of failed implants was 2.1 mm, on average. CONCLUSION: Astra Tech implants placed in the maxillary molar region had generally good survival rates, but the relationship between reduced pre-implant alveolar bone height and implant failure requires further attention.

Damage to adjacent teeth is one of the various complications that may occur during implant placement and is often the result of improper direction during fixture placement or excessive depth of placement. In general, if detrimental symptoms, such as reaction to percussion in damaged teeth, mobility, and pulp necrosis, are not present, osseointegration should be observed at follow-up. In three cases, the possibility of root damage due to an implant fixture placed too close to each adjacent tooth was perceived on radiographs. However, in all of these cases, there were no clinical symptoms or radiographic changes present in the tooth, and the implants did not exhibit decreased stability or peri-implantitis. Therefore, we can carefully predict that the implant fixture close to the adjacent tooth did not invade the cementum of the root, and therefore did not produce the suspected pulpal damage or periradicular symptoms. In this study, we considered both the implant status as well as the adjacent tooth.

Canine adenovirus type 2 (CAV-2) is the cause of a major respiratory illness in dogs. In this study, we analyzed adenovirus infections in dogs using 2000–2017 data from the Animal and Plant Quarantine Agency (APQA) and conducted a serological survey of CAV-2 infection in six animal species in Korea. In total, 38 of the 3,179 dog samples were confirmed as canine adenovirus infections. In serological survey, 1,028 dog sera, 160 raccoon dog sera, 100 cattle sera, 257 sow sera, 206 horse sera, and 106 cat sera, collected from January 2016 to July 2018, were screened for the presence of anti-CAV-2 antibodies by virus neutralization test. The seropositivity rates for dogs, raccoon dogs, cattle, sows, horses, and cats were 88.5% (910/1,028), 51.3% (82/160), 85.0% (85/100), 48.6% (125/257), 35.0% (72/206), and 2.8% (3/106), respectively. Among dogs and raccoon dogs, 1.9% (20/1,028) and 8.8% (14/160), respectively, had a virus-neutralizing antibody (VNA) titer of over 1:256. A high CAV-2 VNA titer indicates a repeated vaccination or natural infection in Korean dogs and circulation of CAV-2 in raccoon dog populations.

This study describes pathological, immunohistochemical, and bacteriological findings in adult dogs and fetuses naturally infected with Brucella (B) canis. A total of 42 dogs including 40 dogs and 2 aborted fetuses were examined. The most common gross lesions in infected dogs were swelling of lymph nodes and spleen. The testes showed marked swelling with multifocal to diffuse reddish discoloration. The most significant histopathological lesions were observed in the placenta. Placental trophoblasts were markedly hypertrophied due to the accumulation of intra-cellular gram-negative bacteria. Lymphocytic inflammation of varying severity was observed in the reproductive organs such as male testis, epididymis, and prostate gland and female uterus. Strong immunolabelling was observed in the cytoplasm of most trophoblasts in the placental tissues using immunohistochemistry. However, immunohistochemical staining did not demonstrate any organisms in other organs of dogs and fetuses. B. canis isolates were most frequently obtained from the whole blood (82.5%) and superficial inguinal lymph node (77.5%) in both sexes. In addition, the isolation rate was higher in male genital organs than in those of females. Hence, management of male dogs is most important because infected dogs can play a role as carriers.

A survey was performed in Korea to monitor the prevalence of five bovine arboviruses [Akabane virus, Aino virus, Chuzan virus, bovine ephemeral fever (BEF) virus, and Ibaraki virus] in arthropod vectors, such as Culicoides species. To determine the possible applications of survey data in annual monitoring and warning systems in Korea, we examined the prevalence of bovine arboviruses in arthropod vectors using RT-PCR. To compare the sensitivity and specificity of virus detection, nested PCR was also performed in parallel for all five viruses. Using the RT-PCR, the detection limits were at least up to 10(1.5), 10(2.8), 10(2.0), 10(1.8), and 10(4.0) TCID50/ml for Akabane virus, Aino virus, Chuzan virus, BEF virus, and Ibaraki virus, respectively. When nested PCR was performed using 1 micronl of PCR product, the detection limits were increased, to 10(0.05), 10(1.8), 10(1.0), 10(0.008), and 10(2.0) TCID50/ml for Akabane virus, Aino virus, Chuzan virus, BEF virus, and Ibaraki virus, respectively. Thus, nested PCR increased the sensitivity of the virus detection limit by 1~2 log. We pooled 30~40 mosquitoes in one sample. We collected 113 samples in 2006, 135 samples in 2007, and 100 samples in 2008. Among these samples, Chuzan virus and BEF virus genes were detected at a range between 0.82% and 1.19%, and Akabane virus, Aino virus, and Ibaraki virus genes were detected at less than 0.20%. These data may provide some insight into future epidemiological studies of bovine arboviral diseases in Korea.

Aino virus infection is characterized by abortion, stillbirth, and congenital abnormalities such as arthropgryposis-hydranencephaly syndrome in calves. In Korea, Aino virus infection was first reported in 1997 by researchers who were investigating the cause of newborn calf deformities. Given the incidence of Aino-related deformities, the need for a study of the Aino virus infection status in Korea was recognized. In this study, we investigated the nationwide seroepidemiological status of Aino virus infection. A total of 9,921 serum samples collected between 1993 and 2001, and 23,760 serum samples between 2002 and 2007 were tested using a virus neutralization assay. The seroprevalence of Aino virus was 73.1, 63.8, 44.9, 56.0, 38.5, 28.4 18.3, 19.6, and 23.2%, respectively, between 1993 and 2001, and 43.8, 42.9, 50.7, 55.3, 31.4, and 25.4%, respectively, between 2002 and 2007. Aino virus infection does not pose a major threat to the bovine industry in Korea till now. The future prospects for Aino virus infection in cattle, however, may change with the global warming phenomena. The results of this study may serve as a basis for future epidemiological studies on Aino virus infection.
