A renal infarct is too rare a disease for early diagnosis and treatment. Furthermore, it presents nonspecific symptoms in many patients. Cardiac diseases such as valvular heart disease and arterial fibrillation are the most common causes of renal infarct. Vascular disease such as renal artery dissection or aortic dissection, trauma, inflammation, vasculitis, malignancy and antiphospholipid syndrome have been also known as possible causes of renal infarct. In acute pancreatitis, adjacent vessels can be involved, and were reported to induce splenic infarction, portal vein thrombosis and superior mesenteric vein thrombosis etc. However, the renal infarct from renal artery involvement in acute pancreatitis has not yet been reported. In our case, a 46 year old male patient had an abdominal trauma due to an in-car accident to develop a rupture of pancreatic tail. The progression of acute pancreatitis caused the inflammation of left renal artery, leading to renal artery obstruction. We report a case of renal infarct developed in acute pancreatitis.

OBJECTIVE: Graft survival rate has been improved due to newly developed immunosuppressive agents, care of recipient and operative method. However, since many risk factors are still threatening the graft survival, many studies have been underway to identify such factors, one of which has been on delayed graft function(DGF). Extending the definition of DGF to oliguria within 2 months postoperative period(POP), we began this study in order to evaluate what effects oliguria within 2 months POP have on graft survival and what are the risk factors involved. METHODS: 103 patients who have had renal transplantation performed were divided into two groups (oliguric group and non-oliguric group), based on the presence or absence of oliguria within 2 months POP. Risk factors such as the recipient factors(age, gender), donor factors(age, gender), operative factors(warm ischemia time, intraoperative urine volume), HLA typing, postoperative hypotension, postoperative hypovolemia were compared between the two groups and the impact of oliguria on graft outcome was also analysed. RESULTS: 1) 14 were Oliguric patients and 89 were nonoliguric patients. 2) One-year graft survival rate was 40% in the oliguric group and 98% in the non-oliguric group(P<0.05). 3) As the result of analyzing the risk factors, non living related donor(living non-related donor and cadaver donor) were 7(50%) in the oliguric group and 16(18%) in the non-oliguric group(P<0.05). The mean intraoperative urine volume was 442m1 in the oliguric group and 774m1 in the non-oliguric group(P<0.05). The occurrence of postoperative hypotension were 5(36%) in the oliguric group and 1(1%) in the non-oliguric group(P<0.05). Other risk factors such as the recipient fractors, donor factors, warm ischemia time, HLA typing and postoperative hypovolemia were not significantly different between the two groups. CONCLUSION: Graft survival rate in the oliguric group was lower than in the non-oliguric group. The risk factors for oliguria were non living related donor, intraoperative urine volume lower than 500m1 and postoperative hypotension. In conclusion, renal transplantation from non living related donor needs to be proceeded with caution; the maintenance of intraoperative urine volume and the prevention of postoperative hypotension are essential for better graft outcome.

Duodenal diverticulum is commonly found at 2nd portion of duodenum undergoing duodenal procedure. It is generally asymptomatic and not harmful. But occasionally it causes massive upper gastrointestinal bleeding. Bleeding from duodenal diverticulum is very difficult to diagnose and manage since vision of the lesion by conventional direct endoscope is limited. Recently, emphasis has been placed on aggressive and careful endos- copic diagnosis and hemostasis with hemoclip or local injection. We report a case of massive duodenal diverti- cular bleeding on a senile patient which was treated successfully by endoscopic hemoclip therapy.

Hyperhomocyst(e)inemia is an established risk factor for atherosclerosis. We performed this study to identify the correlating variables and risk factors for atherosclerosis, as measured by the atherosclerotic score (AS), and to determine the relative risk for cardiovascular disease in relation to plasma homocyst(e)ine levels in patients on chronic hemodialysis. We evaluated and measured 61 patients on chronic hemodialysis for clinical and biochemical parameters including atherosclerotic score (AS) and plasma homocyst(e)ine. We divided patients into high and low groups, first, by the mean AS, and second, by the median value of plasma total homocyst(e)ine levels. Then we compared the variables between the two groups. Out of the 61 patients, the median plasma total homocyst(e)ine level was 24.4 micromol/L (mean+/-SD, 27.7+/-17.4; range, 9.8-127.4 micromol/L), and the median AS was 5 (mean+/-SD, 6.2+/-2.8; range, 3-13) out of a possible 20 points. AS was significantly correlated with plasma total homocyst(e)ine levels (r=0.37) and age (r=0.67). Through multivariate analysis, plasma total homocyst(e)ine level and age were determined as significant risk factors for the high-AS group (p<0.05). However, plasma total homocyst(e)ine level did not correlate with age (p>0.05). Eighteen of the 61 patients, presented with cardiovascular disease until the present study, had an AS>6. Cardiovascular disease was found more often in the high-homocyst(e)ine group (>24.4 micromol/L) than in the low-homocyst(e)ine group (odds ratio, 9.3; 95% confidence interval, 2.3-37.4). Regardless of age, hyperhomocyst(e)inemia (especially homocyst(e)ine levels >24.4 micromol/L) is a risk factor that can be modified for the development of cardiovascular disease in patients on chronic hemodialysis.

STUDY DESIGN: A molecular biological study of intercostal muscles and intervertebral disc cells of Korean scoliosis patients. OBJECTIVES: To study the pathological results of intercostal muscles and molecular biological activity of intervertebral disc cells of the scoliotic major curve in Korean patients. SUMMARY OF LITERATURE REVIEW : The cause of idiopathic scoliosis has been investigated in terms of many parameters. Although, molecular biological studies of intercostal muscles and intervertebral disc cells have been performed in foreign countries, few studies have been conducted in Korea. MATERIALS AND METHODS: Ten patients, one male and nine female, who underwent thoracoscopic surgery were reviewed. The age range was 13 to 23 years old. Intercostal muscles were taken from the portal site of the major curve (1x1 cm sized). Ten tissues were stained with H/E and ATPase immunohistochemical staining. An appropriate amount of intervertebral disc was taken from the major curve of three scoliotic patients and each concentration of collagen type I, II, GAG gene and proteoglycan synthesis activity was measured. The results were compared with those of grade 0 and grade II degenerative change on each MRI. RESULTS: The intercostal muscle of scoliotic patients showed 60.4+/-8.4% in type I muscle fiber and 39.6+/-8.8% in type II-A. These results were not different from those of previous studies. The size of muscle fiber was 48-65 microns, which was slightly smaller than the absolute value, but the difference was not statistically significant. The amount of produced proteoglycans was slightly higher in the intervertebral disc cells of scoliotic patients, the total amount of collagen was significantly lower and there was a difference in the production of type II collagen. CONCLUSIONS: The intercostal muscles were not affected by the muscle of scoliotic patients and there was no molecular biological significant difference between control and scoliotic patients. We can assume that scoliosis was not caused by problems of intervertebral disc or intercostal muscles.

In cases of symptomatic AOVM of the brainstem, there is a great risk of progressive morbidity caused by repetitive hemorrhage, and the condition can even be fatal. To establish the optimum method of management of this condition, we investigated 15 patients treated between January 1991 and January 1996. Seven lesions were located in the pons, three in the medulla, three in the midbrain, and one each at the pontomedullary and pontomesencephalic junction. Surgery was performed in six cases in which the lesions were close to the dorsal pial surface of the brainstem ; the histological diagnosis was five cases of cavernous angioma and one of arteriovenous malformation. Nine patients with surgically inaccessible lesions, deep seated or located in the midbrain, were treated by gamma knife radiosurgery. All patients who underwent surgery showed neurologic improvement, and among those who underwent radiosurgery, the outcome was favorable. For symptomatic lesions located in the dorsal pial surface of the pons or medulla, surgical resection is the treatment of choice, and prevents further neurological disability and rehemorrhage. For the best possible outcome, intraoperative sonography and electrophysiologic monitoring are mandatory. Gamma knife radiosurgery can be employed in selected cases in which lesions are deep-seated and inaccessible and associated with repeated hemorrhage and progressive neurologic deficit.

Longitudinal standards for height and height velocity are essential to monitor for appropriate linear growth. We aimed to construct standards in Korean children and adolescents through the population-based longitudinal Kangwha study. Our study was a part of a community-based prospective cohort study from 1986 to 1999 with 800 school children. Height and height velocity were recorded annually from age 6 until final height. Results were compared with cross-sectional data from the 2007 Korean National Growth Charts. Final height was 173.5 cm in boys and 160.5 cm in girls. Although final height was similar between longitudinal and cross-sectional standards, the mean height for age was higher in the longitudinal standard by 1-4 cm from age 6 until the completion of puberty. Using the longitudinal standard, age at peak height velocity (PHV) was 12 in boys and 10 in girls; height velocity at PHV was 8.62 cm/yr in boys and 7.07 cm/yr in girls. The mean height velocity was less than 1 cm/yr at age 17 in boys and 15 in girls. Thus, we have presented the first report of longitudinal standards for height and height velocity in Korean children and adolescents by analyzing longitudinal data from the Kangwha cohort.
