BACKGROUND: Truck driving is known as one of the occupations with the highest accident rate. This study investigates the characteristics of traffic collisions according to road types (expressway and rural road). METHODS: Classifying 267 accidents into expressway and rural road, we analyzed them based on driver characteristics (age, working experience, size of employment), time characteristics (day of accident, time, weather), and accident characteristics (accident causes, accident locations, accident types, driving conditions). RESULTS: When we compared the accidents by road conditions, no differences were found between the driver characteristics. However, from the accident characteristics, the injured person distributions were different by the road conditions. In particular, driving while drowsy is shown to be highly related with the accident characteristics. CONCLUSION: This study can be used as a guideline and a base line to develop a plan of action to prevent traffic accidents. It can also help to prepare formal regulations about a truck driver's vehicle maintenance and driving attitude for a precaution on road accidents.

5.Genetic Studies in Human Prion Diseases.

Journal of Korean Medical Science 2014;29(5):623-632
Human prion diseases are fatal neurodegenerative disorders that are characterized by spongiform changes, astrogliosis, and the accumulation of an abnormal prion protein (PrP(Sc)). Approximately 10%-15% of human prion diseases are familial variants that are caused by pathogenic mutations in the prion protein gene (PRNP). Point mutations or the insertions of one or more copies of a 24 bp repeat are associated with familial human prion diseases including familial Creutzfeldt-Jakob disease (CJD), Gerstmann-Straussler-Scheinker syndrome, and fatal familial insomnia. These mutations vary significantly in frequency between countries. Here, we compare the frequency of PRNP mutations between European countries and East Asians. Associations between single nucleotide polymorphisms (SNPs) of several candidate genes including PRNP and CJD have been reported. The SNP of PRNP at codon 129 has been shown to be associated with sporadic, iatrogenic, and variant CJD. The SNPs of several genes other than PRNP have been showed contradictory results. Case-control studies and genome-wide association studies have also been performed to identify candidate genes correlated with variant and/or sporadic CJD. This review provides a general overview of the genetic mutations and polymorphisms that have been analyzed in association with human prion diseases to date.

BACKGROUND/AIMS: The endoscopic mucosal resection has now been adopted for a useful modality in both curative therapy and accurate diagnosis of early gastric cancer. A retrospective study was done to evaluate the indication and the limitation of endoscopic mucosal resection of early gastric cancer. METHODS: We studied 20 cases of early gastric cancer treated by endoscopic mucosal resection in Chungnam National University Hospital from November, 1995 to July, 1997. RESULTS: 1) The size affected the curability: 83. 3% of lesions less than 2 cm and 50. 0% of those larger than 2 cm were resected completely. 2) The depth of cancer invasion affected the curability: 87. 5% of lesion confined to mucosa were resected completely, while all of submucosal cancers were resected incompletely. 3) Among fourteen cases resected completely, three cases of lesions larger than 2 cm were residual cancer and two of those less than 2 cm were recurred locally. CONCLUSIONS: To be a curative therapy by endoscopic mucosal resection of early gastric cancer, we think that careful selection of the lesion, that is lesion less than 2cm and confined to mucosa, is necessary

The Ankle joint is a modified complex hinge joint which plays an importnat role in weight bearing, walking and standing. Injuries about the ankle joint cause destruction of not only bony architecture but also the ligament and soft tissue components. We performed arthrography in 52 cases of ankle fracture. The Result obtained from this study was as follow; The ligament & interosseous membrane injuries were more severe, when fracture of lateral malleolus was occured higher level than ankle joint.

Acute pyogenic arthritis in renal transplant patient is one of the serious problem resulting in significant morbidity and mortality. The purpose of this paper is to analyze seven patients in whom acute pyogenic arthritis developed following renal transplantation. Pyogenic arthritis developed in seven (0.7%) out of 958 renal transplant patients whose transplanted kidney functioned well for more than two years. The age of the patients ranged from 37 to 65 years with a mean of 48 years. All patients were male. Pyogenic arthritis developed between the period of one and 12 years (mean: 4.5+/-4.2 years) following transplantation. Causative organisms were Staphylococcus aureus (three), E. coli (two), Salmonella (one) and Acinetobacter bananii (one). Involved joints were four knees, one hip, one elbow and one finger. Two patients improved on a conservative regimen of bed rest and antibiotics and five patients required open drainage. However, pyogenic arthritis recurred in three years, four years and seven years after renal transplant in one patient. Looking at the probable risk factors of age, sex, immunosuppresants, diabetics and acute graft rejection, diabetics and older age (over 40 years old) are highly associated with post renal transplant pyogenic arthritis.

PURPOSE: This study was designed to investigate the significance of preoperative serum CA 19-9 level as a prognostic factor and postoperative serum CA 19-9 level as an indicator for recurrence in gastric adenocarcinoma patients. MATERIALS AND METHODS: 328 patients, who received curative resection of stomach for gastric cancer from 1989 to 1996 and followed up successfully, were analyzed retrospec- tively. Median follow-up period was 24 months (range: 11-38 months). The cut off level of serum CA 19-9 was 37 U/ml. The relationships between preoperative serum CA 19-9 status and prognostic parameters, recurrence and survival rate were analyzed. Multivariate analysis using Cox proportional hazards regression analysis was performed to evaluate as an independent prognostic factor. The relationship between postoperative serum CA 19-9 level and recurrence was investigated. RESULTS: Out of 328 cases, 29 cases (8.8%) showed elevated preoperative serum CA 19-9 level. The preoperative serum CA 19-9 level was correlated with the degree of depth of invasion and the status of lymph node metastasis (p<0.05). Patients with positive pre- operative serum CA 19-9 status showed higher incidence of recurrence (p<0.05) and poorer survival rate (p=0.00003) than patients with negative status. Preoperative serum CA 19-9 status (risk ratio: 3.4464, p=0.0039) revealed as an independent prognostic factor in multivariate analysis. Postoperative serum CA 19-9 status revealed as a useful predictor for recurrence in patients with positive preoperative serum CA 19-9 status. CONCLUSION: Preoperative serum CA 19-9 determination in patients with gastric cancer was valuable for predicting tumor progression and prognosis. Preoperative serum CA 19-9 status may be helpful to predict recurrence earlier than other diagnostic tools, especially in the patients with positive preoperative serum CA 19-9 status.
