Purpose : When the mature kidney fails to reach its norml location in the renal fossa, the condition is known as ectopic kidney. Presenting symtoms can be various and it generally depend on the associated anomaly. Beside urologic anomalies such as hydronephrosis and vesicoureteral reflux, various anomalous vascular net work, skeletal anomaly or genital anomaly can be observed in this condition. Methods : Sixteen children with ectopic kidney was studied retrospectively to analyse initial presentation, accompanied anomaly and prognosis. Results : 56% of the children were accompanied with other urologic anomalies such as true incontinence and vesicoureteral reflux that required surgical treatment. 31% of children were either diagnosed incidentally during evaluation of other non-urologic disease or during follow-up evaluation of abnormal antenatal renal sonogram. Conclusion : Ectopic kidney can be often misdiagnosed as tumorous condition or as a surgical condition depend on the abnormal location of the kidney. Careful evaluation using abdominal sonogram, DMSA, VCUG and abdominal CT scan should be performed in order to search for associated anomalous condition and for proper management.
Purpose: This study was performed to evaluate the role of colonoscopy in children with hematochezia. Methods: We retrospectively reviewed the medical records of 277 children who underwent colonoscopy because of hematochezia between January, 2003 and July, 2010. Results: The mean age of the patients was $6.0{\pm}4.4$ (7 days~17.8 years) years. The male to female ratio was 2.2:1. The duration between the 1st episode of hematochezia and colonoscopy was $4.9{\pm}12.1$ months. Characteristics of hematochezia included red stool (65.1%), blood on wipe (12.8%), bloody toilet (11.9%), and blood dripping (10.2%). The most proximal region of colonoscopic approach was terminal ileum (84.5%), cecum (9.5%), hepatic flexure (2.8%), and splenic flexure (3.2%). Eighty five patients (30.6%) had no specific abnormal findings. Major causes of hematochezia were polyp (26.4%), food protein induced proctocolitis (6.9%), infectious colitis (5.4%), lymphofolliculitis (5.7%), non specific colitis (5.7%), and vascular ectasia (5.1%). The hemorrhagic sites included the rectum (24.0%), rectosigmoid junction (18.1%), sigmoid colon (13.5%), ascending colon (14.2%), transverse colon (11.3%), descending colon (7.8%), cecum (8.1%), and terminal ileum (3.1%). The recurrence rate of hematochezia after colonoscopy was 19.1%. Colonoscopy was performed in 262 patients (94.6%) with conscious sedation. Endoscopic hemostasis was performed in 5 patients. Complications of colonoscopy or sedation were not found. Conclusion: The causes and lesional localization of pediatric hematochezia were diverse. Colonoscopy has an important role in the diagnosis and treatment of hematochezia in children. Total colonoscopy is recommended to detect the cause of hematochezia.

This study was conducted to survey vegetation changes and soil characteristics in Saemangeum new reclaimed tidal land. Soil salinity in border area to tidal land was 22.3 dS $m^{-1}$ but showed 1.1~3.44 dS $m^{-1}$ over the distance of 2 km from border line. The vascular plants in survey sites were recorded as total 26 taxa in 6 families. The frequency of species appearance of Aster tripolium, A. subulatus var. sandwicensis were highest by 61.5 and that of Phragmites communis, Puccinellia nipponica were 53.8. The almost vegetations occurred in the patch which range of soil salinity 14 dS $m^{-1}$ were halophytes as Salicornia europaea, Suaeda asparagoides, S. japonica. As lowed soil salinity as 6.7 dS $m^{-1}$, mixed vegetation of halophytes with P. communis, P. nipponica, Carex pumila were occurred. Dominant species in the range of 3.0 dS $m^{-1}$ area were A. subulatus var. sandwicensis, P. communis, Echinochloa spp., Zoysia sinica and Conyza canadensis. Biomass production was the highest in the area of dominant vegetation with P. communis, and mixed zone with P. communis and Aeschynomene indica are followed. The correlation between vegetation biomass and soil salinity, soil pH and dominance index of vegetation were negative. But that of vegetation biomass and soil organic content were positive.
To know the feasibility of the coronary artery bypass graft (CABG) for multivessel coronary artery disease with purely bilateral internal thoracic arteries (ITAs), we analyzed the short-term clinical results and the coronary angiography of the patients. Material and Method: From March 2001 to June 2002, four hundred and five patients underwent CABG. Purely bilateral ITAs were used in 159 patients (39.3%). We analyzed these patients retrospectively The mean age of these patients was $61.2{\pm}8.5$ (range: 30 ~80) years and there were 123 male patients. The preoperative risk factors were as follows: diabetes in 54 patients (34.0%), history of acute myocardiac infarction within 4 weeks in 29 (18.2%), and emergency operation in 6 (3.8%). Off-pump CABG was carried out in 128 patients (80.5%). Associated procedures were mitral valvuloplasty (5), aortic valve replacement (3), Dor procedure (1), and so on. Result: The mean number of distal anastomoses was $3.1{\pm}0.9$ (range: 2~6), the mean duration of hospital stay was $8.4{\pm}4.5$ days. There was one (0.6%) operative death. Except for one early death, no other patients suffered from low cardiac output. The other postoperative complications were occurred as follows: reoperation due to bleeding in 3 patients, perioperative myocardiac infarction in 1, transient cardiac arrest in 2, transient cognitive dysfunction in 7, and transient ischemic attack in 1, and deep sternal wound infection in 1 patient. Recently, early postoperative angiography was performed in 19 patients who had triple vessel disease. The total number of distal anastomosis was 78 (mean $4.1{\pm}0.8$/patient). All distal anastomosis sites were patent, but competition flow was observed at the bypass sites where the native coronary artery stenosis was not significant. Conclusion: The CABG with purely bilateral ITAs for triple vessel disease was performed safely. The early patency rate was relatively good in small number of patients. However the long-term patency rate and the functional study to evaluate the sites where competition flow was observed should be followed.
Even though there well developments in various treatment techniques for acute limb ischemia, this disease is both life threatening and limb threatening. We investigated early and mid-term results of operation for acute limb ischemia with symptoms, the combined diseases, location of occlusion, complication in our patients. Material and Method: A retrospective review was conducted in 54 patients (43 men, 11 women, mean age 67.2 years) presenting with acute limb ischemia due to arterial thrombosis or embolism between Jan. 1996 and Dec. 2003, initially underwent thromboembolectomy. Result: In 33 patients (61.1%) the timeinterval from the onset of symptom to admission was within 24 hours. Causes of acute limb ischemia were embolic occlusion (27.8%), native arterial thrombosis (66.7%), and bypass graft thrombosis (5.6%). The distribution of arterial occlusion location was at 8 aortoiliac (14.8%) and 43 distal to femoral (79.6%) and brachial (5.6%). Clinical categories were grade I in 64.8%, IIa in 24.1%, IIb in 7.4%, and III in 3.7%, All the patients were received embolectomy. Underlying diseases were heart disease (72.2%), hypertension (33.3%), cerebrovascular accident (16.7%) and diabetes (18.5%). History of smoking was noted in 96,3% of the cases. Mortality rate was 5.6% and overall amputation rate was 9.3% (5/54). The 1-year limb salvage rate was 93.62%. Postoperative complications were 1 wound infection, 1 G1 bleeding, 3 acute renal failure, and 1 compartment syndromes. The functional outcomes of the salvaged limb according to the recommended scale for gauging changes in clinical status, revised version in 1997 were +3 in 68.5%, +2 in 9.3%, +1 in 7.4%, -1 in 5.6%, -2 in 3.7%, and -3 in 5.6%. Conclusion: This study revealed 5.6% mortality and the amputation rate was 9.3%. We have retrospectively shown good results from early diagnosis & early operation. To improve outcome, early diagnosis and understand the underlying diseases, prompt treatment and operation would be appreciated.
Background: Ischemia reperfusion injury is known to contribute to the major causes of the early graft failure in lung transplantation. Triiodothyronine (T3) has been suggested to ameliorate ischemia reperfusion injury from both in vivo and in vitro experiments of various organs. Prospecting its beneficial effect for pulmonary allograft preservation, we made a new solution by adding T3 into the extracellular type dextran solution. Material and Method: Twelve adult mongrel dogs underwent left lung allotransplantation. Six donor dogs were flushed with the new solution(Group 1, n=6), and the remaining six were flushed with Euro-Collins solution to serve as controls(Group 2, n=6). Allografts were stored in each preservation solution for 20 hours at 4$^{\circ}C$. Left single lung transplantations were performed. The right pulmonary artery and the right main bronchus were clamped at 15 minutes after the reperfusion and maintained throughout the experiment to evaluate the transplanted left lung function. Result: Arterial carbon dioxide tension was better in group 1 than in group 2 throughout the experiment period and the difference was statistically significant at 2 hours after reperfusion(28.0${\pm}$3.0 mmHg and 53.1${\pm}$17.4 mmHg, p<0.05). The differences of arterial oxygen partial pressure, peak airway pressure and pulmonary vascular resistance showed no statistical significance. The malondialdehyde(MDA) level, measured from tissue obtained at 120 minutes after reperfusion showed no statistically significant difference. The tissue wet/dry ratio of group 1(649${\pm}$27 %) was significantly lower than that of group 2(686${\pm}$71 %, p<0.05). The microscopic examination revealed varying degrees of injury represented mainly by findings such as perivascular neutrophil infiltration, capillary hemorrhage and interstitial congestion. These findings were less severe in group 1 than those in group 2. Conclusion: The new solution demonstrated superior allograft preservation after 20 hour ischemia compared to Euro-Collins solution in canine single left lung transplantation model, these results suggest that T3 might be a promising agent for pulmonary allograft preservation.
Background: Calcific degeneration limits durabilities of the bioprosthetic tissues implanted in the human body. The direct coupling sulphonated polyethyleneoxide(PEO-SO3) to the bioprosthetic tissues after glutaraldehyde(GA) fixation and the removal of residual aldehyde groups from the tissues can augment the effect of calcification-resistance. Materials and methods: To study the anti-calcification effect by PEO-SO3 modification and the removal of the residual aldehyde groups of tissues, surface modified bovine pericardia(BP-PEO-SO3) were preserved in aseptic saline to wash out GA(saline group) and 0.65% GA solution(GA group). And then above two groups and PERIGUARD (Bio-vascular. Co.) (product group) were evaluated with respects to calcium contents and microscopic findings using in vivo implantation models at carotid and femoral artery and peritoneum of 8 adult dogs. Results: In the tissues retrieved from carotid artery, calcium content was significantly decreased in saline group than in other two groups(saline; 2.89±0.31 vs. GA; 6.14±1.08 vs. product; 22.82±5.00 mg/g of dried tissue; p<0.05). In the tissues retrieved from femoral artery and peritoneum, calcium amount was also decreased in saline group than in other two groups, but not reached the significant difference between groups. On the other hand, the pathologic findings of pericardial tissues showed marked destructuction in GA group compared to the other two groups. Conclusions: In this study, covalently PEO-SO3 bound to bovine pericardium decreased calcifications and the anti-calcification effect of BP-PEO-SO3 could be augmented by the washing out the residual aldehyde groups using saline after GA fixation. Conclusively, the PEO-SO3 modified bovine pericardium is highly resistant to calcification and can be useful for the development of calcification-resistant cardiovascular patches and valves.
It is to be growing up the interest of community health affairs through visiting nursing care. The health medical treatment of Korea has been changed largely on the period. The juvenile population has decreased. This means that is has took the population consensus of advanced national organization to be increased by the old age. The transition of disease has changed from the contagious disease importance to the chronicity disease omportance because the domestic district population has experienced the sudden urbanization circumstance district population has experienced the sudden urbanization circumstance to be growing up $70\%$ of the whole population. When the nursing service has common function to be delivering from all direction to home, this study is getting the great important phase velocity in order to manage the kernel questional adult chronicity disease of health medical institution at the present age. (1) community over system or with people particularity (2) the first of third step medical treatments. The variety of medical treatments organization has quantity of the delivery manpower and specially between consumers and rdlated person. A qualitative difference is showed at the purpose to be seizing. That research related person is use at district health center in Seoul, by foundation on nurse registration book of H collage hospital and public health registration book. According the chronicity disease. age. and sex. nature agree-able standard 54 people took the content analysis on nurse registration book of total 108 people. The results of the study were as follows: 1. General background factors are houses or kind of medical facilities and number of patients in family. The first medical treatment is more patients than third medical treatment organization. The first medical treatment of economic environment os appering to be worse. 2. The chronicity disease frequency have been different speciality according to medical treatment organization. On case of the first medical treatment. Diabetes and High Blood Pressure were good but Cerebrum Vascular Accident(CVA) showed many for bed case. In addition. the number of family is comparative large exception of CVA on according for moving condition and health more than the first medical treatment. However. family condition. whole family percentage is decreasing preferably through the potential resource is increasing by the number of and the construction of family. The ability of real resource is considered to be low. 3. The average percentage of nurse service has appered to be differed two groups by the first step medical treatment(33.72 times) and third step medical treatment(45.70 times). However, the difference (the first step medical treatment and third step medical treatment) is to be limited to issue the medicine at the service. The condition of nurse care was the indirect nursing care. Supportiong area was to be related to volunteer service and administration support. 4. The various nursing care average percentage of the chronicity disease was increased by orders of Diabetes. High Blood Pressure. and CVA in examination result and the medical treatment. The indirect nursing care was also same. At third step medical treatment, orders of chronicity disease were same. The case of other area on service conditions were increased by order of Diabetes. High Blood Pressure, and CVA. However. it is never appearing the difference at bottleneck affairs nursing care. 5. When the visiting nursing care demand particularly. the average percentage of nursing care from the first step medical treatment that the time under a person is many more than the time over two people. However, there was no difference in statistic. Third step medical treatment is $49.81\%$ at the time under a person. The average nursing care service is appeared by more many when the visiting nursing care demand is a few by 12.83 at the time over two people. 6. By visiting nursing care percentage to be frequency that nursing care averaghe percentage and inter-relation are large. The related factor of the first medical treatment is 0.96. However, the related factor of third medical treatment has shown the decreased 0.49 for the condition of relation more than that. Therefore. the nursing care average percentage is related to the visiting times of a nurse. This result is be showing the obvious fact that the first step medical treatment is few more than third step medical treatment.
Purpose : Forward pulmonary blood flow may be absent in some neonates with Ebstein's anomaly by anatomical or functional pulmonary atresia in association with the elevated pulmonary vascular resistance, patent ductus arteriosus and tricuspid regurgitation. We reviewed the presentation and outcomes of symptomatic neonates with Ebstein's anomaly focusing on the pulmonary atresia. Methods : Clinical presentation and outcome of 15 symptomatic neonates with Ebstein's anomaly seen at Asan medical center from 1998 to 2004 were reviewed. Results : Ten(67%) of 15 patients showed no forward pulmonary blood flow and 6 of them had functional pulmonary atresia. $O_2$ saturation and pH were lower and cardiothoracic(CT) ratio in chest radiography was more increased in the patients with pulmonary atresia than in the patients without pulmonary atresia(P<0.05). pH and CT ratio were not different between the anatomical and functional pulmonary atresia group, but $O_2$ saturation was lower in functional atresia group(P<0.05). 13 patients(87%) were managed with $PGE_1$. 4 of 6 patients with functional pulmonary atresia were treated with inhaled nitric oxide. Surgery was performed in 1 of 5 patients without pulmonary atresia and in 8 of 10 patients with pulmonary atresia during follow-up period(mean 37 months). 3 patients(20%) died and none of patients without pulmonary atresia died. Conclusion : We found that most symptomatic neonates with Ebstein's anomaly had functional or anatomical pulmonary atresia. The neonates with Ebstein's anomaly who had no forward pulmonary blood flow were more symptomatic and needed surgery earlier. Further studies will be needed to distinguish effectively functional and anatomical pulmonary atresia and to manage appropriately neonates with functional atresia.
Purpose : High-Sensitivity C-reactive protein(hs-CRP) has been recognized as a very useful and sensitive predictor of the future risk of myocardial infarction. But the clinical significance of hs-CRP in children remains uncertain. To confirm the existence of obesity-induced vascular inflammation and the association between metabolic syndromes and elevation of CRP in children, we investigated the relationship among CRP, obesity, blood pressure(BP), and serum lipids in schoolboys. Methods : Twenty-eight obese(BMI $29.61{\pm}3.29kg/m^2$) and 93 non-obese(BMI $18.99{\pm}2.21kg/m^2$) boys aged 14 years were examined. Serum CRP levels was measured by the high sensitive latex turbidimetric immunoassay and subjects with CRP levels below 0.3 mg/dL were adopted to avoid the influence of acute infection. Results : Obese children had significantly higher hs-CRP levels than their non-obese group($0.104{\pm}0.075$ vs. $0.054{\pm}0.005mg/dL$). In the obese group, BMI, systolic blood pressure, diastolic blood pressure, apolipoprotein B, atherogenic index, and triglyceride were significantly higher than in nonobese. The BMI, diastolic blood pressure, apolipoprotein E, atherognic index, and triglyceride showed positive correlation with log CRP by simple regression. Multiple regression analysis indicated that BMI and apolipoprotein E were strongly related to CRP. Conclusion : This study revealed that obese children tended to have higher levels of serum hsCRP, BP elevation and dyslipidemia than the control group and that BMI and apolipoprotein E were strongly related to CRP. These results indicate that obesity related metabolic syndrome can be developed in children.
