A case of chondromyxoid fibroma, which was experienced at Seoul National University Hospital, is presented with a brief review of the literature, because of its relative rarity in incidence, its unusual location and its huze size in demension which seems to be largest in reported series in literatures.

Catatracts are an infrequent but well-known complication of electrical injury, remains poorly understood. We report two cases of electric cataract with maculopathy experienced recently. The first case was a 58-year-old man who had exposed to 22000 voltage current and sustained third degree, 15% burn. 54th day after burn, the lenticular changes showed total opacity of both eyes and the intraocular pressure of left eye was 28 mmHg. 65th day after burn, extracapsular cataract extraction with posterior chamber lens implantation on left eye was performed. After the operation, naked vision was 1.0, but hard exudates were showed in macular area. The second case was a 23-year-old man who had exposed to 54000 voltage current and sustained third degree, 20% burn. 82th day after burn, the lenticular changes showed moderate opacities in the anterior and posterior subcapsular area of both eyes. 137th day after burn, extracapsular cataract extraction with posterior chamber lens implantation on right eye was performed. The final corrected visual acuity was 0.5 on 7th week after the operation due to lamellar macular hole.

Recently there has been remarkable improvement in the treatment of chondrosarcoma, accompanied with the development of diagnostic tools, operative technique, replacement materials and designs, anticancer-chemotherapy and radiotherapy. In well-deferentiated chondrosarcom, wide excision is the only treatment required. Nevertheless, in dedifferentiated chondrosarcoma, anticancerchemotherapy or radiotherapy is usually recommended after the wide excision. From 1984 to 1994, 22 patients diagnosed as chondrosarcoma had been treated at Seoul National University Hospital. We analysed anatomic distributions, size, methods of treatment and their results. The avereage age was 38 years and 10 months(15 years 73 years) and the average follow-up period was 3 years and 10 months(1 year and 6 months

PURPOSE: To compare the incidence between author's first and current report on urinary tract stone in patient with spinal cord injury and to evaluate the effectiveness of recent developed in medical technology and care on in treating the patients. MATERIALS AND METHODS: We reviewed urinary tract stone in 257 patients with paraplegia or quadriplegia after spinal cord injury. These patients were diagnosed retrospectively by KUB and intravenous urography at the Korea Veterans Hospital during 10years from January, 1984 to December, 1993. We evaluated and compared the overall incidence, incidence of specific location of urinary tract, recurrent rate, incidence according to the level of spinal cord injury, and the duration of development in urinary tract stone. RESULTS: Total patients were 257 with 186(72.4%) paraplegia and 71(27.6%)quadriplegia. Overall incidence of the stone was 16.0% in this study and 38.1% in the first study. Incidence of the stone in individual organ ;5.5% in kidney, 1.2% in ureter, and 13.6% in urinary bladder. The recurrent rate was 29.3% in this study and 40.6% in the first study. Incidence of the stone according to the level of spinal cord injury was as follows;15.6% in cervix, 17.1% in upper thorax, 17.9% in lower thorax and 13.9% in lumbar. The stone developed during the first 4 years and between 12 to 16 years following spinal cord injury was 28.3% each. CONCLUSION: Overall incidence and recurrent rate of urinary tract stone was obviously decreased since the first study. Highest incidence of the stone occurred in urinary bladder and in patient with lower thoracic spinal cord injury, which is similar to first report. Peak incidence of the stone was in the first 4years, and another peak was in 12-16years after spinal cord injury. The decreased overall incidence of urinary tract stone maybe attributable to the development in medical technology and care, and active rehabilitation.

Authors measured the degree of posterior instability of the knee in 21 patitients who had posterior cruciate ligament(PCL) injury or have been reconstructed the PCL by using the manual maximal displacement test and quadriceps active test with KT-1000 arthrometer. To compare the reliability between the manual maximal displacement test and the quadriceps active test, two testers participated in the experiment. One tester was a novice and the other tester had substantial clinical experiences with the KT-1000 arthrometer. The quadriceps neutra! Angle was measured in the uninjured knee, and then quadriceps active test was done. Manual maximal displacement test and Quadriceps active test were done by each tester. In manual maximal displacement test, the Pearson correlation coefficient of the uninjured knee between two testers was 0.852 and that of PCL injured knee between two testers was 0.802. In quadriceps achive test, the Pearson correlation coefficient between two testers was 0.173. As a result, the manual maximal displacement test was more reliable for th measurement of the degree of the posterior instability in patients with posterior cruciate ligament tear or reccnstruction.

The alert regarding the emergence of novel influenza was issued by the WHO on April 24th, and the government has taken immediate actions to respond to the situation since then. Based on the presumption that a pandemic was imminent, countermeasures for the H1N1 influenza pandemic have been prepared by establishing and implementing effective public health crisis strategies over the past few years. Our main strategy during the pandemic influenza crisis has shifted in accord with the corresponding National Disaster Phases. In the Caution (Containment) Phase, our main goal was to contain the influx of disease from overseas. We focused on measures such as entry screening and quarantine inspection while monitoring travelers arriving from affected countries. In the Alert Phase I, our aim was deceleration and prevention of secondary community outbreaks through enhanced early detection. We intensified our surveillance and response system for possible mass outbreaks. During Alert Phase II, as the influenza had spread widely, our tactics switched to minimizing social and economic impact and preventing severe cases with early administration of antiviral agents, especially among high-risk patients. In the current Severe Phase, we are trying to reduce mortality cases with intensive care. Since we have implemented mass vaccination, we predict an early termination of the pandemic.

The cytologic examination of voided urine and bladder washings was done in 220 patients with bladder tumors from January, 1986 to June, 1989. Sixty hundred and thirty six specimens including 415 voided urine specimens and 221 bladder washings were examined. Among those, 160 paired specimens of both voided urine and bladder washings were taken from one patient on the same day. Specimens were stained by the Papanicolaou method, and they were interpreted as being negative when the cytologic examination was normal or showed benign atypia and positive when malignant cells were suspected or clearly evident. Sensitivity and specificity of the cytologic examination were 41.8%, 91.9% as a whole, and 34,6%, 96.6% in voided urine and 54.4%, 82.4% in bladder washings. The sensitivity of voided urine and bladder washings was increased as the tumor size, number, grade and stage were increased. A positive urine cytology without a visible tumor in voided urine was seen in 5 cases and the tumor recurred in all 3 patients who were followed up for more than 3 months. Among fifteen cases of a positive cytology without a visible tumor in bladder washings, 9 cases were followed up for more than 3 months, and the tumor recurred in 2 of 9 cases. In conclusion, the voided urine and bladder washings were complementary for the diagnostic accuracy of cytologic examination, and careful follow-up is necessary for a patient with a positive cytology without a visible tumor.
