Fracture of acetabular are relatively uncommon, but when they occur they seem to pose management difficulties for attending surgeon. They are, however, important injuries because they may give rise to disabling symptoms. Furthermore, they are increasing in frequency due to the increasing number of traffic accidents. Forty cases of acetabular fracture were treated in the National Medical Center during the period 1980 to 1987. The short summary of observation were as follows : 1) There was a preponderance of young patients, the majority being in the 31–40 age group(68%). The ratio between males and females was 2.6:1. 2) The most common cause of injury was traffic accident(68%). 3) The most common associated fracture was pelvic bone fracture(48%), and most common associated other injury was abdominal visceral injury(30%). 4) The most common fracture was posterior wall fracture(28%) following to Judet & Letournel's anatomocal clsssification. 5) Twenty-five fracture(63%) were treated by conservative measures, and 15 fractures (37%) were treated by open reduction and internal fixation. 6) The results were as follows : excellent in 13(33%), good in 19(47%), fair in 5(13%), and poor in 3(7%). 7) The complication of acetabular fracture were traumatic arthritis in 6 cases, sciatic nerve injury in 2 cases, avascular necrosis of femoral head in 2 cases. 8) Not only choice of treatment but also determination of surgical approch require accurate assessment of the fracture pattern in this region of complex bony architecture by careful radiologic analysis.

High tibial osteotomy is now an accepted procedure in the treatment of osteoarthritis of the knee. Since the effect of this procedure is to shift the line of weight bearing from one compartment of the other, the procedure is of value in knees with osteoarthritis only when there is predominant involvement of one compartment. The osteoarthritis of knee developed bilaterally in many case, so simultaneous bilateral high tibial osteotomy under one anesthetic was considered. Eight cases of osteoarthritis with genu varum deformity were treated by simultaneous bilateral high tibial osteotomy at the Department of Orthopaedic Surgery of NMC during the,period from January, 1984 to December, 1987. The results were as follows: l. All case were female, and the mean age was 56 years old. 2. Preoperative mean varus angle were 4° in right, 3.4° in left, and postoperative mean valgus angle were 8° in right, 6° in left at final follow-up. 3. The results after average 2.2 years of follow-up were as follows: good in 5 cases(63%), fair in 1 cases(12%), poor in 2 cases(25%) 4. The complications were one proximal tibial fracture, one displacement of distal fragment, and one transient peroneal nerve palsy. 5. Mean immobilization period was 7 wks and mean hospitalization period was 48 days. 6. More rigid internal fixation was recommended in simultaneous procedure to reduce the period of hospitalization and early ambulation.

OBJECTIVE: Teeth discoloration is a rare orthodontic complication. The aim of this study was to report the clinical progression of discoloration during orthodontic treatment. METHODS: Discolored teeth, detected during orthodontic treatment between January 2003 and December 2012 by a single dentist using similar techniques and appliances, were analyzed. RESULTS: The total number of teeth that showed discoloration was 28. Progression of discoloration was evaluated in only 24 teeth that were observed without any treatment. During the observation period, the discoloration “improved” in 8 of the 24 teeth (33.3%) and was “maintained” in 16 (66.6%). The electric pulp test performed at the time of initial detection of discoloration showed 14.3% positivity, which improved to 21.4% at the final follow-up. None of the initial and final follow-up radiographic findings showed any abnormalities. CONCLUSIONS: When teeth discoloration is detected during orthodontic treatment, observation as an initial management is recommended over immediate treatments.

Microsatellite mutator phenotype (MMP) tumors were reported in a subset of gastrointestinal carcinomas. The molecular pathogenesis of MMP tumors shows defects in the DNA mismatch repair genes, and also many germline and somatic mutations were reported in the MMP tumors. However, the detection of genetic defects in the MMP tumors is very difficult, mainly because many genes are included in the DNA mismatch repair genes. This study was undertaken to determine the best strategy for detecting defects in the DNA mismatch repair genes in gastrointestinal carcinomas. One of the effective ways for detecting defects in DNA mismatch repair genes is to screen the MMP tumors and evaluate the products of DNA mismatch repair genes by performing the multiplex RT-PCR method. We have screened the MMP tumors by using 5 microsatellite markers in the 12 cancer cell lines, 120 colon carcinomas and 99 gastric carcinomas and found 6 MMP cell lines, 10 MMP colon cancers, and 9 MMP gastric carcinomas. In addition, we evaluated 6 DNA mismatch repair gene products (hMSH2, hMSH3, hMSH6, hMLH1, hPMS1 and hPMS2) by multiplex RT-PCR analysis and found decreased expression of the DNA mismatch repair genes in 5 (hMSH6 in DLD-1 and HCT-15; hMSH2 in LoVo; hMLH1 and hMSH3 in HCT-116; hMLH1 in SNU-638) out of 6 MMP cell lines. We also found a decreased expression of hMLH1 in 3 out of 10 MMP colon carcinomas, and in 6 out of 9 MMP gastric carcinomas. Our results indicate that the expression analysis of the DNA mismatch repair genes by multiplex RT-PCR method can reduce the number of genes subjected to mutational analysis and is convenient for screening the responsible DNA mismatch repair genes.

We observed 285 cases of culture proved shigellosis from Jan. 1978 to July 1981 at W.M.B.H. in Busan. We specially observed the clinical and bacteriological response to Oxolinic acid in 59 cases from Jan. to July 1981. The following results were obtained. 1. The most commonly isolated shigella strains was Sh. flexneri (85.3%) followed by Sh. sonnei (7.4%), Sh. boydii (4.2%) and Sh. dysenteriae(3.2%). 2. Antibiotic sensitivity test revealed that more than 90% of strains were resistant to Tetracycline, Chloramphenicol and Ampicillin. Resistance strains to Gentamycin and Oxocid were found in less than 12.2% and 14.3% respectively. 3. The multiple antibiotic resistant strains were observed in about 80% of 59 strains, which were resistant to 3~5 antibiotics. The most of these strains were resistant to Ampicillin, Chloramphenicol and Tetracycline. In 3 cases it was resistant to all kinds of antibiotics but oxolinic acid. 4. Oxolinic acid showed growth-inhibitory zone of more than 11 mm with the concentration of 2mcg/ml in 95% and M.I.C. value of less than 0.76mcg/ml in 90%. 5. After administration of Oxolinic acid, there was clinical response within 2 days in 76.5% and conversion to negative stool culture within 2days in 68.8%. 6. Compared with placebo group, there was parallel clinical and bacteriologic effectiveness between Oxolinic acid and Rifampin.

BACKGROUND/OBJECTIVES: This study was conducted to examine relationships between dietary habits and intakes of antioxidants and B vitamins and the risk of ischemic stroke, and to compare dietary factors according to the presence of cerebral artery atherosclerosis and stroke subtypes. SUBJECTS/METHODS: A total of 147 patients and 144 control subjects were recruited consecutively in the metropolitan area of Seoul, Korea. Sixty participants each in the case and control groups were included in analyses after 1:1 frequency matching. In addition, 117 acute ischemic stroke patients were classified into subtypes according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) guidelines. Dietary intake was measured using a semi-quantitative food frequency questionnaire composed of 111 food items and plasma lipid and homocysteine levels were analyzed. RESULTS: When compared with control subjects, stroke patients had unfavorable dietary behaviors and lower intakes of fruits (73.1 ± 83.2 g vs. 230.9 ± 202.1 g, P < 0.001), vegetables (221.1 ± 209.0 g vs. 561.7 ± 306.6 g, P < 0.001), and antioxidants, including vitamins C, E, B₆, β-carotene, and folate. The intakes of fruits, vegetables, vitamin C, and folate were inversely associated with the risk of ischemic stroke after adjusting for confounding factors. Intakes of vegetables, vitamins C, B₆, B₁₂, and folate per 1,000 kcal were lower in ischemic stroke with cerebral atherosclerosis than in those without. Overall vitamin B₁₂ intake per 1,000 kcal differed according to the TOAST classification (P = 0.004), but no differences among groups existed based on the post-hoc test. CONCLUSIONS: When compared with control subjects, ischemic stroke patients, particularly those with cerebral atherosclerosis, had unfavorable dietary intake, which may have contributed to the development of ischemic stroke. These results indicate that proper dietary recommendations are important for the prevention of ischemic stroke.

Toxic epidermal necrolysis(TEN) is a severe drug induced life-threatening disease and an acute illness. This disease is characterized by rapid onset of widespread necrosis resulting in sloughing of epidermis. The incidence of TEN is very rare, with approximately 0.5 to 1.4 cases per million per year. but TEN has a high mortality rate of 25-40 percent. Therapy for TEN is primarily aimed at supportive care. Treatment with systemic corticosteroid, immunosuppresive agent such as cyclosporine, cyclophosphamide, pentoxifyllin or plasmapheresis have not been shown to improve outcome. Recently, administration of high dose intravenous immunoglobulin(IVIG) has been shown to result in rapid improvement in patients with TEN. There have been several reports of the benefit of IVIG in adult patients with TEN. However we could not find using IVIG in pediatric patient with TEN in Korea. We have experienced improvement in a 2 years old boy with TEN after using high dose IVIG.
