This study was carried out on 178 bus drivers in the Masan area to investigate their health and nutritional status. THe nutritional status of the subjects was surveyed using a self-administered questionnaire, and blood analyses were conducted through annual health examinations in June, 1999. The results were as follows: About 51% were classified as normal, 33% as health-concerned, and 17% as disease-suspected. The levels of total serum cholesterol were significantly higher in the over 20 year group (194.64 +/- 41.42 mg/dl) than in the under 10 year group (175.00 +/- 31.33 mg/dl) with respect to the length of their driving careers. Systolic blood pressure (SBP) was significantly higher in the 51 to 60 age group than in the other groups (p < 0.05). The total serum cholesterol increased with increasing age (p < 0.001), and SBP increased with increasing Body Mass Index (BMI)(p < 0.001). Diastolic blood pressure (DBP), total cholesterol (p < 0.01), hemoglobin (p < 0.05)and glutamate-pyruvate-aminotransferase (GPT)(p < 0.05) were significantly higher in the BMI of over 20, than in the BMI under 20. The GPT was significantly higher in the BMI over 25 than in the BMI under 25. In The mean daily energy intake was 1912.7 kcal (76.5% of the RDA) and the protein intake was 74.3 g (106.2% of the RDA). Compared with the recommended allowance, the energy, calcium, thiamin, and riboflavin intakes were below, and the Fe, vitamin A, vitamin C intakes were above the Korean RDA. The average carbohydrate, protein, fat ratio of energy intake was 66 : 15 : 19, respectively. The length of their driving careers had a positive correlation with their ages and total serum cholesterol levels, and their ages had a positive correlation with their blood pressures, total serum cholesterol and hemoglobin levels and BMI. Their BMI had a positive correlation with their ages, blood pressures, total serum cholesterol, hemoglobin, GPT and GOT levels. The results of this study indicate that bus drivers needed regular exercise, and control of their body weights to prevent chronic diseases, and that their health status should be monitored as the length of their driving careers and ages increase.

This study investigated the correlation between health-related habits and the biochemical characteristics of the blood of Korean bus drivers. A total of 178 bus drivers working in the Masan area participated in this study. The general characteristics and health-related habits of the subjects were surveyed using a serf-administered questionnaire. The biochemical date were collected from regular health check-ups done through their workshop health insurance company in lune, 1999. The results were as follows : The average age of the subjects was 38 years, and 44.2% had a driving career of between 10 and 19 years. About 90% of the subjects ate irregularly, and 36% ate. health floods. Their rates of drinking, smoking and exercise were 74.6%, 83.6% and 70.8%, respectively. Their frequency of drinking was significantly increased as the length of their driving career increased (p<0.001). Their levels of total serum cholesterol, in relation to the length of their driving career was significantly higher in the over 20 year group than in the below 10 year group (p<0.05). Their systolic blood pressures, according to age, were significantly higher in the 51 to 60 age group than in the other groups (p<0.05). Their total um cholesterol levels signiscantly increased with increasing age (p<0.001). Their diastolic blood pressures (p<0.001) and blood glucose levels (p<0.05) were significantly higher among the subjects who drinking alcohol almost everyday, than among other subjects. Their systolic blood pressures who significantly increased with increasing frequency of their drinking (p<0.001). The systolic blood pressure and diastolic blood pressure were positively related to age, the amount of drinking, the frequency of drinking and the obesity index, and negatively related to exercise and the duration of exercise. The hemoglobin was positively related to age, preference for a meat diet and the obesity index. The blood glucose was positively related to the amount of drinking, and the total serum cholesterol was positively related to age, length of driving career, period of smoking and the obesity index. The results of this study indicated that bus drivers need regular exercise, moderation of their drinking and smoking, and control of their body weights so as to prevent chronic diseases.

PURPOSE: To give a help in the interpretation of cardiac cine-MR examination, the extent, shape, and timing of appearance of signal void regions near atrioventricular(A-V) valve prospectively evaluated in the healthy population. MATERIALS AND METHODS: Using an axial gradient-echo technique with small flip angle, repetition time(TR) of 36 msec and echo time(TE) of 22 msec, 20 volunteers without known valvular abnormalities undertook cardiac cine-MR imaging including atrioventricualr valve areas. RESULTS: Transient signal void was observed within the atrium near the tricuspid(13/20 = 65%) and mitral valves(9/20 = 45%), respectively, which is so called "physiologic atrioventricular valvular insufficiency". Eight subjects revealed the signal void areas near both tricuspid and mitral valves but, 5 subjects didnot show any evidences of physiologic insufficiency. This physiologic condition does not extend more than lcm proximal to A-V valve plane and is generally observed only during early systole. Its morphology is semilunar or triangular configuration with the base to the valve plane in most cases of normal tricuspid insufficiency and small globular appearance in most cases of normal mitral insufficiency. CONCLUSION: Awareness of normal signal void areas near the A-V valve and their characteristics is critical in the interpretation of cardiac cine MR examinations and maybe helpfal in the study of the normal cardiac physiology.

Breast conserving surgery (BCS) with radiation therapy (RT) has been considered an alternative to a radical mastectomy in the surgical treatment of early breast cancer. Breast-conserving therapy (BCT) can achieve a more favorable cosmetic outcome than a mastectomy in patients with early breast cancer. However, it is widely recognized that RT following BCS is an impediment to improve the cosmetic outcome of a BCT-treated breast. If the local recurrence (LR) rate is acceptable and LR can be controlled with salvage surgery, an appropriate conservative surgical procedure without RT will be a reasonable option for some patients with early breast cancer. Between 1990 and 1996, 60 patients were enrolled in a retrospective study to examine whether or not RT could be avoided following conservative surgery in patients with early breast cancer. There was no significant difference in local recurrence rate between the RT and the non-RT groups (6.3% vs 10.7%). The characteristics of suitable BCS without RT would be negative axillary lymph-node metastasis, low nuclear grade, a 1 cm negative resection margin and no lymphatic vessel involvement. In conclusion, breast-conserving surgery without RT is a reasonable option for some patients with early breast cancer.

Emergency surgical repair for acute traumatic aortic ruptures has been associated with a high peri-procedural mortality rate. Endovascular stent-grafting, as a less invasive procedure, has shown encouraging results. This report describes a patient with a short landing zone, who was treated by transposing the supra-aortic branch without sternotomy, followed by covered stent-grafting with an extended proximal bare portion to enhance fixation.

PURPOSE: To report a case of corneal ulcer due to Alcaligenes xylosoxidans in a soft contact lens wearer. CASE SUMMARY: A 20-year-old female patient presented with a corneal ulcer. The patient had been wearing soft contact lenses over 6 months. The ulcer had a typical appearance, similar to that of immune infiltration due to contact lenses. However, the corneal scraping and culture yielded Alcaligenes xylosoxidans, which is susceptible to ceftazidime and levofloxacine in the antibiotic susceptibility test. After treatment with topical antibiotics, her eye improved, with only a mild corneal scar remaining. CONCLUSIONS: Alcaligenes xylosoxidans should be considered as a potential causal pathogen of keratitis upon wearing soft contact lenses. Additionally, any lesion should be suspected as a bacterial corneal ulcer, even if appearing as an immune infiltration due to contact lenses.

Bony lesions of the glenoid and Hill-Sachs lesions are the most common injuries after a first-time traumatic shoulder dislocation. However, fracture of the coracoid process after traumatic shoulder dislocation is rare. A single, open surgical procedure could be performed by a Latarjet procedure using a fractured fragment of the coracoid process. If a fracture of the coracoid process is associated with a traumatic anterior shoulder dislocation, the Latarjet procedure may be the most appropriate surgical option.

Background: A previous study reported that hyperlipidemia increases the incidence of tears in the rotator cuff tendon and affects healing after repair. The aim of our study was to compare the gene and protein expression of torn rotator cuff tendons in patients both with and without hypercholesterolemia. Methods: Thirty patients who provided rotator cuff tendon samples were classified into either a non-hypercholesterolemia group (n=19, serum total cholesterol [TC] <200 mg/dL) and hypercholesterolemia group (n=11, serum TC ≥240 mg/dL) based on their concentrations of serum TC. The expression of various genes of interest, including COL1A1, IGF1, IL-6, MMP2, MMP3, MMP9, MMP13, TNMD, and TP53, was analyzed by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). In addition, Western blot analysis was performed on the proteins encoded by interleukin (IL)-6 and TP53 that showed significantly different expression levels in real-time qRT-PCR. Results: Except for IGF1, the gene expression levels of IL-6, MMP2, MMP9, and TP53 were significantly higher in the hypercholesterolemic group than in the non-hypercholesterolemia group. Western blot analysis confirmed significantly higher protein levels of IL-6 and TP53 in the hypercholesterolemic group (p<0.05). Conclusions We observed an increase in inflammatory cytokine and matrix metalloproteinase (MMP) levels in hypercholesterolemic patients with rotator cuff tears. Increased levels of IL-6 and TP53 were observed at both the mRNA and protein levels. We suggest that the overexpression of IL-6 and TP53 may be a specific feature in rotator cuff disease patients with hypercholesterolemia.
