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.

BACKGROUND: There has been a change in the causes of aortic stenosis when comparence of rheumatioc aortic stenosis in recent year. Therefore, we studied the etiology factor of pure aortic stenosis. METHODS: The gross surgical pathologic features of the aortic valves were reviewed in 92 patients with pure aotic stenosis whom underwent aortic valve replacement at Yonsei University, Cardiovascular center between July 1989 and June 1994. RESULTS: The three most frequent causes were 1) calcification of congenital bicuspid valve in 30%, 2) degenerative calcification of aortic valve in 22%, 3) rheumatioc valvular change in 48%. The mean age at the time of aortic valve replacement for the entire series of patients was 54.4 years. The range of age was from 18 years to 77 years. Males predominated for degenerative disease and congenital bicuspid valves, but there were reversed rheumatic origin. One or more complications occured in 17% of patients undergoing operation. The surgical mortality was 3.3%. CONCLUSION: Our data suggest that more common cause of aortic stenosis is non-rheumatic disease rather than rheumatinc origin.

BACKGROUND: High-frequency jet ventilaion is considered a reliable technique for anesthesia and critical care including respiratory failure but there are adverse reactions such as carbon dioxide retension and dry of respiratory mucosa. The purpose of this study was to confirm the effects of combined high- frequency jet ventilation (HFJV) and converntional mechanical ventilation (CMV) on the cardiovascular system, arterial blood gases tension and mean airway pressure in 9 Korea mongrel dogs with pulmonary edema induced by oleic acid. METHODS: During CMV with 20 breaths/minute, 10 ml/kg of tidal volume and F1O2 1.0, parameers were evaluated (base line value). When pulmonary edema was developed, HFJV was applied initially with 120 breaths/minute, inspiratory time 30% and driving pressure 40 psi F1O2 1.0 for 60 minutes (control value) and thereafter simultaneous use of CMV was applied with the tidal volume of 10 ml/kg and each respiratory rate 8, 4, 2, 1, 0.5 per minute for 30 minutes. RESULTS: Combined application of HFJV and CMV (above repiratory rate 1 per minute) achieved the improvement of oxygenation and carbon dioxide elimination, and Paw was decreased without undesirable effects on cardiovascular system in case of the induced pulmonary edema. CONCUSIONS: From above results we recommanded that HFJV combined with CMV may be a useful method of treatment for respiratory failure.

Cystic lymphangioma are rare benign tumors that originate as a congenital anomaly of the lymphatic system. Their common presentation is in neck and axillary area at the birth, during infancy or early pediatric age group. Author reports an unusual case of cystic lymphangioma of breast which was diagnosed in a 32-year-old woman. The findings were very dense, sharply defined, and multilobulated masses on mammography, and mu-Itiloculated echo free lesions on ultrasonogram.

The purpose of this study was to findout the characteristics of helminthic infection, especially. those of Ascaris lumbricoides infection in the slum, population residing in suburban Seoul. This study was conducted on 301 slum residents in Machun-Dong, Kangnam-Ku, Seoul on August, 1977. The results of this study could be summarized, as follows: 1) The prevalence rate of Ascaris lumbricoides among 194 subjected residents was 59.8 percent. The highest prevalence was observed in the age group of 0~9 years (prevalence rate: 65 per cent). 2) The average. E.P.G. of A. lumbricoides were found to be 3,100 in 111 infected cases and this fingure was also the highest in the age group, 0~9 years. 3) After chemotherapy with pyrantal pamoate in dose of 10mg/kg disregarding the results of stool examination, satisfactory follow-up stool collection for worm detection could be performed in I54 cases, among 301 subjected cases. Out of the 154 cases, 97 (63per cent) passed out Ascaris worm(s) and the average worm burden was 4.7 per infected cases. The analysis of collected data revealed that the prevalence rate was higher in female, although, the worm burden per infected case was higher in male residents. The children aged 0-9 years harbored the worms as much as adults. 4) By observing the collected worms an4 discriminating the reinfected young Ascaris aged less than 2-months, it was found that the reinfection occurred in 14 per cent of residents in a month and average amount of reinfection was 0.205 per month per person. These two reinfection, indices were also the highest in children. From the above results, it was concluded that the reinfection of Ascaris lumbricoides was . actively occurred in the residents of the slum area and the children in this area were the most seriously affected by the infection.

Pulmonary vein stenosis is a rare condition which is usually congenital in origin and is almost invariably fatal in its bilateral and severe forms. It is often overlooked, however, during clinical examination, routine echocardiography, and even at cardiac catheterization. This report describes pulsed Doppler, color flow echocardiography, and hemodynamic findings of bilateral pulmonary vein stenosis accompanying ventricular septal and atrial septal defects successfully corrected by surgery.

PURPOSE: To evaluate the pattern of colonic diverticulosis according to age and sex, and recent trend. MATERIALS AND METHODS: The authors retrospectively reviewed 120 cases of colonic diverticulosis in 1,020 patients who had undergone a double contrast barium enema examination between January 1st, 1993, and December 31st, 1995, and analyzed the frequency, size, multiplicity and anatomical site, according to age and sex. Diverticulum size was classified into one of three groups : less than 5mm, 5-10mm, over 10mm in diameter. RESULTS: The overall incidence of colonic diverticulosis was 120 cases among 1,020 patients(11.8%) with an incidence 5.3 times higher in males than in females. Peak incidence was in the fifth decade, with 19 cases (15.8%) among males, and after the sixth decade, with four cases(3.3%) among females. Mean age was 57.7 years. Diverticulum size of 5-10mm in diameter was predominant 2% of cases) ; average diameter was 5-6mm. The incidence of colonic diverticulosis was 5.1 times more frequent in the right colon(101 cases) than in the left (20 cases). CONCLUSION: The overal overall incidence of colonic diverticulosis has continually increased; in addition it has also recently increased slightly in left-sided colon. This is thought to be due to various factors, both congenital and acquired, including longer life with good health care, constipation, irritable bowel syndrome, stress and the tendency of eating patterns to more closely resemble those of the west.
