A case of congenital orbital teratoma with marked unilateral proptosis was noted at birth. Patients with congenital orbital teratoma had a uniform clinical picture and were very similar in their morphologia1 pattern, often polycystic and with varied amounts of solid tissue. Six months after birth the tumor and eyeball were totally extirpated through combined efforts of the services of ophthalmology and plastic and reconstructive surgery, and a skin graft was performed. Histological examination revealed components from all three germinal layers and no sign of malignancy. The present case is of particular interest because of the rarity and the typification of congenital orbital teratoma.

Osteoma is a benign tumor arising from cancellous or compact bone. Frontal sinus is the most common site, followed by the ethmoidal sinus, maxillary sinus, sphenoidal sinus, maxilla and mandible. Very few cases involving the mandible have been described. A 26-year-old woman who had a limited range of mouth opening was reffered to our clinic. The limited opening had been gradually increasing in severity after first operation(reduction malarplasty and angle resection). Computed tomography images showed a radiopaque mass between left mandibular notch and zygomatic arch. After surgical removal of mass, diagnosis of mass was osteoma from clinical pathology. The postoperative course was uneventful, the patient could open the mouth about 40 mm, 5 months after the operation.

Larvae of Bradysia agrestis, an insect vector that transports plant pathogens, were sampled from geographically isolated regions in Korea to identify their cutaneous fungal and bacterial flora. Sampled areas were chosen within the distribution range of B. agrestis; each site was more than 91 km apart to ensure geographical segregation. We isolated 76 microbial (fungi and bacteria) strains (site 1, 29; site 2, 29; site 3, 18 strains) that were identified on the basis of morphological differences. Species identification was molecularly confirmed by determination of universal fungal internal transcribed spacer and bacterial 16S rRNA gene sequences in comparison to sequences in the EzTaxon database and the NCBI GenBank database, and their phylogenetic relationships were determined. The fungal isolates belonged to 2 phyla, 5 classes, and 7 genera; bacterial species belonged to 23 genera and 32 species. Microbial diversity differed significantly among the geographical groups with respect to Margalef's richness (3.9, 3.6, and 4.5), Menhinick's index (2.65, 2.46, and 3.30), Simpson's index (0.06, 0.12, and 0.01), and Shannon's index (2.50, 2.17, and 2.58). Although the microbial genera distribution or diversity values clearly varied among geographical groups, common genera were identified in all groups, including the fungal genus Cladosporium, and the bacterial genera Bacillus and Rhodococcus. According to classic principles of co-evolutionary relationship, these genera might have a closer association with their host insect vector B. agrestis than other genera identified. Some cutaneous bacterial genera (e.g., Pseudomonas) displaying weak interdependency with insect vectors may be hazardous to agricultural environments via mechanical transmission via B. agrestis. This study provides comprehensive information regarding the cutaneous microflora of B. agrestis, which can help in the control of such pests for crop management.

OBJECTIVES: The aim of this study was to describe subjective physical and mental health assessed by the single item self-rated physical health (SRPH), and self-rated mental health (SRMH) had influence on the cognitive decline in community-dwelling elderly. METHODS: This study was based on the Suwon Project, a cohort comprising of non-random convenience samples of ethnic Koreans aged 60 years and above. 1,356 individuals were assessed at 2 time points 2 years apart for questionnaire which included demographic characteristics, medical history, Korean Mini-Mental State Examination (K-MMSE), Korean version of Geriatric Depression Scale (SGDS-K), SRPH, and SRMH. Multiple logistic regression was used to assess K-MMSE score change from the SRPH, and SRMH. RESULTS: At baseline, both SRPH (beta=0.18, p<0.01) and SRMH (beta=0.19, p<0.01) score positively associated with the K-MMSE score. At follow-up, subjects with baseline lower SRMH score had significantly greater decline in K-MMSE score (beta=0.09, p=0.007). However, baseline SRPH score showed no effect to follow up K-MMSE score before and after adjusting age, sex, education, number of chronic disease, SGDS-K, and baseline K-MMSE score (p=0.89). CONCLUSION: Brief and easily collected subjective mental health may predict the risk of cognitive decline, but subjective physical health may not.

Onion (Allium cepa L.) is an economically important vegetable crop worldwide. However, various fungal diseases, including Fusarium basal rot (FBR), neck rot, and white rot, reduce onion production or bulb storage life. FBR caused by Fusarium species is among the most destructive onion diseases. In this study, we identified Fusarium species associated with FBR in Jeolla and Gyeongsang Provinces in South Korea and evaluated fungicides against the pathogens. Our morphological and molecular analyses showed that FBR in onions is associated with Fusarium commune,Fusarium oxysporum , and Fusarium proliferatum. We selected seven fungicides (fludioxonil, hexaconazole, mandestrobin, penthiopyrad, prochlorazmanganese, pydiflumetofen, and tebuconazole) and evaluated their inhibitory effects on mycelial growth of the pathogens at three different concentrations (0.01, 0.1, and 1 mg/mL). We found that prochloraz-manganese was highly effective, inhibiting 100% of the mycelial growth of the pathogens at all concentrations, followed by tebuconazole. Fludioxonil showed < 50% inhibition at 1 mg/mL for the tested isolates.cc

OBJECTIVE: Head circumference (HC) has been reported to be an index of cognitive functioning in the elderly and in Alzheimer's patients. The object of the study is to find the relationship between HC and cognition. METHODS: A total of 7,603 subjects over 60 years of age were analyzed from preliminary data of Gwangju Dementia and Mild Cognitive Impairment Study. HC was manually measured and cognitive functioning was assessed by the Korean version of the Mini Mental State Examination (K-MMSE). RESULTS: Correlational analysis showed that HC was associated with age (r=-0.14, p<0.01), education (r=0.33, p<0.01), height (r=0.26, p<0.01), and K-MMSE (r=0.28, p<0.01). Also, even after adjusting for confounding variables (age, education, height, gender) the positive association between HC and K-MMSE score remained significant (beta=0.18, p<0.001). CONCLUSION: The results suggest that HC may play an important role in predicting cognitive impairment in the elderly.
