Aneurysm of the sinus of Valsalva is fairly rare. Between 1987 and 1994, we operated on a total of 12 cases of aneurysm of the sinus of Valsalva at the Inje University Seoul Paik Hospital. This represents 0.7% of all cardiac operation under cardiopulmonary bypass. There were eight male and four female patients aged from 8 to 38 years(mean, 19.2 years). 8 of 12 patients had ruptured aneurysms. The origin of aneurysm of the sinus of Valsalva was the right coronary sinus in 10(83. 3%), and the noncoronary sinus in 2(16.6%). In ruptured aneurysm, the origin was the right oronary sinus in 6, and the noncoronary sinus in 2. The aneurysms originating from the right coronary sinus ruptured into the right ventricle in 5, and into both the right atrium and right ventricle in 1. The aneurysms originating from the noncoronary sinus ruptured into the right ventricle in 1, and into the right atrium in 1. Associated congenital cardiac defects included ventricular septal defect in 10(83.3%) patients 39 cases of these were associated with the aneurysms of the right coronary sinus), aortic regurgi- tation in 3 (all of these had an additional ventricular septal defect), mitral regurgitation in 1, and double chambered right ventricle in 1. No hospital deaths occurred, although one late death occurred as a result of endocarditis 15 months after the first operation. The mean follow-up period was 29 months, range from 4 to 60 months. Eleven patients except one late death were in New York Heart Association class 1. Due to the low mortality risk o( an operation for aneur sm of the sinus of Valsalva, a ruptured aneurysm of the sinus of Valsalva should be corrected surgically when the diagnosis is mane, and unruptured aneurysm of the sinus of Valsava with complication should also be operated. In most cases the aorta was opened to examine the morphology of the aneurysm and the aortic cusps, and an associated aortic valve defect should be corrected simultaneously.

Purpose : The cause and pathogenesis of Henoch-Sch$\ddot{o}$nlein purpura (HSP) are unknown, but recently the hypothesis that immunoglobulin A may have an important role in the pathogenesis of HSP is being published and HSP associated with mycoplasma infection has been also reported. The aim of this study is to discover relation between HSP and mycoplsma infection. Methods : From Jan. 2002 to Dec. 2005, we retrospectively evaluated 98 children who were diagnosed as HSP at Ilsan Paik Hospital. 84 patients were not associated with mycoplasma infection (group A) and 14 patients were associated with mycoplasma infection (group B). We compared both groups about clinical features. Results : The ratio of male to female patients in group A and B were 1.21:1 and 1.80:1. The number of patients in group A was most in November and December, and in group B was most in November. All patients had non-thrombocytopenic purpura concentrated on the buttocks and lower extremities and joint involvement was most common on the feet and ankle in both groups. 57 (67.9%) cases in group A and 9 (64.3%) cases in group B complained of abdominal pain. And 21 (25.0%) cases in group A and 5 (35.7%) cases in group B had nephritis. Elevated mycoplasma antibody titer (${\geq}1:320$) or 4 fold-rise were noted in 14 of 98 patients (14.3%). In this study, there was one child with HSP preceded by typical mycoplasma pneumonia (mycoplasma antibody titer 1:1280). Conclusion : In this study, elevated mycoplasma antibody titer (${\geq}1:320$) or 4 fold-rise were noted in 14 of 98 patients and the difference of clinical features between group A and B was not specific. The role of mycoplasma infection in the etiology of HSP may have been implicated, so the association with mycoplasma infection should have to be proved by further controlled studies.

Purpose : Human coronanviruses (hCovs) including hCoV-229E and hCoV-OC43 have been known as etiologic agents of the common colds and were regarded as clinically insignificant agents. However, recent identification of hCoV-NL63 and hCoV-HKU1 in children with lower respiratory tract infections has evoked the clinical concerns about their prevalence and the clinical significance of these hCoVs in children. This study was performed to investigate the prevalence of hCoVs in children with community-acquired pneumonia. Methods : From March 2006 to January 2007, nasopharyngeal specimens collected from children hospitalized with pneumonia, were tested for the presence of common respiratory viruses (respiratory syncytial virus, influenza A, influenza B, parainfluenza viruses, and adenovirus) using multiplex reverse transcriptase polymerase chain reaction (RT-PCR). Human metapneumovirus (hMPV) infection was excluded by nested RT-PCR using primers for the F-gene. To detect the different strains of hCoVs, nested RT-PCR assays specific for hCoVNL63, hCoV-OC43, hCoV-229E, and hCoV-HKU1 were performed. Results : Out of the 217 nasopharyngeal aspirate from children aged under 15 years, respiratory syncytial virus (RSV) was detected in 32 patients, hMPV in 18, human parainfluenza virus in 10, influenza virus A in 2, and adenovirus in 6. HCoVs were detected by RT-PCR in 8 (3.7%) of the 217 patients, hCoV-229E in 1, hCoV-NL63 in 3, and hCoVOC43 in 4 patients. HCoV-HKU1 was not detected in this study population. Conclusion : Recently identified hCoV-NL63 and hCoV-HKU1 seemed to have a little clinical significance in Korean children with severe or hospitalized community-acquired pneumonia.

Purpose : Henoch-Schonlein purpura(HSP) nephritis has been reported to vary from 25 to 50% among HSP patients and is a common cause of chronic glomerulonephritis in children. In our study, we evaluated the distribution and the association of the Insertion/Deletion(I/D) polymorphism of angiotensin converting enzyme(ACE) gene with clinical manifestations, particularly proteinuria in children with HSP nephritis, compared with that in HSP. Methods : ACE gene polymorphism was determined in children with HSP nephritis(n=33) and HSP(n=28) who were diagnosed in Busan Paik hospital from January 1996 to June 2001. The I/D polymorphism of ACE gene was determined by PCR amplication of genomic DNA. Results : The ACE I/D genotype frequency was DD : 25%, ID : 50%, II : 25% in HSP and DD : 24 %, ID : 46%, II : 30% in HSP nephritis, there was no significant difference in the genotype and allele frequencies between two groups. When statistical analysis was done according to the presence of D allele, the amount of 24-hour urinary protein excretion and the incidence of moderate to heavy proteinuria(>$500mg/m^2/day$) at onset and last follow-up were higher in DD/ID genotype than in those in II genotype, but these differences were not statistically significant. Conclusion : We suggest a lack of association between I/D polymorphism of ACE gene and clinical manifestations in children with HSP nephritis. However, further follow-up studies based on a sufficient number of patients and long term follow up periods are necessary to confirm the role of I/D polymorphism of ACE gene in children with HSP nephritis.
Purpose : Recently, different results about factors affecting accurate quantitation of 24-hr urinary protein(24UP) amount using spot urine protein/creatinine ratio(PCR) have been reported. The current study was designed to evaluate correlation between 24UP amounts and PCR in children, and the effect of 24UP amounts, age, sex, and glomerular filtration rate(GFR) on this correlation. Methods : Among 94 patients who visited the department of pediatrics in Busan Paik Hospital from March 2002 to August 2002, 68 patients whose urinary creatinine excretion was ${\geq}15mg/kg/day$ were included in this study. All the patients were divided into I, II/A, B group(I : 24UP<500 mg/day, II : $24UP{\geq}500mg/day$, A : <10 years of age, B : ${\geq}10years$ of age). Pearson correlation analysis was performed between 24UP and PCR to evaluate the relationship. We defined fractional difference between 24UP and PCR, and then performed multiple regression analysis with 24UP amount, age, GFR and fractional difference. Results : There was a strong positive linear correlation between 24UP and PCR(R=0.936, P<0.0001) in all patients, and the correlation was also good in each group. Using PCR cutoff values of 0.5, the PCR provided high sensitivity, specificity, positive and negative predictive value in predicting 24UP amount ${\geq}500mg$. The factors affecting accurate quantitation of proteinuria using spot urine PCR was age, not 24UP amount, GFR or sex. Conclusion : Spot urine PCR is a useful test but has limitations in predicting 24UP amount. Therefore, it should be used only as screening method. Age-adjusted PCR cutoff values may be necessary to predict 24UP amount in children with proteinuria.
Purpose : Hepatitis B virus (HBV) infection has been involved in several forms of immune-related glomerulopathy but the pathogenic role of HBV infection is not clear. To evaluate the clinicopathological features of HBV-associated glomerulopathy, a clinicopathological analysis and immunohistochemical stain for HBs Ag and HBe Ag were done. Methods : Clinicopathological features of HBV-associated glomerulopathy were analyzed with renal biopsies in 28 HBsAg seropositive patients from April 1990 to February 1997 at Pusan Paik Hospital, and immunohistochemical evaluation for HBsAg and HBeAg was done in renal tissues. Light microscopic, immunofluorescent and electron microscopic examination and immunohistochemical staining for HBsAg (DAKO) and HBeAg (BIONIKE) of renal tissue were performed. Result ; 1. The age distribution was 6 to 73 years old, and eight were children and 20 were adults. Male : female ratio was 3:1. Nineteen (67.9%) and 21 (75.0%) of 28 cases showed hematuria and proteinuria, respectively at the time of biopsy. Sixteen (57.2%) of them had nephrotic syndrome. 2. Liver function test was performed in 11 patients and seven (63.6%) of them showed increased AST and ALT levels. Liver biopsy was done in three patients and revealed findings of chronic active hepatitis. 3. HBV-associated glomerulopathy was membranous glomerulonephritis (MGN) in 10 (35.7%), mesangiopathy in 8 (28.6%), membranoproliferative glomerulonephritis (MPGN) in 7 (25.0%) and minimal change disease in 3 (10.7%) out of 28 cases. 4. Ultrastructurally HBV-associated MGN showed conspicuous subepithelial deposits with intramembranous, mesangial and subendothelial deposits and proliferation of mesangial cells and matrix, which were suggestive of MPGN. In HBV-associated MPGN, intramembranous and subepithelial deposits were scattered. 5. Immunohistochemical staining revealed no expression for HBsAg, but positive reaction for HBeAg along capillary wall in 8 cases (28.6%), of which 3 cases were checked for serum HBeAg, all showed positivity. Conclusion : HBV-associated glomerulopathy showed a wide morphologic spectrum and overlapping ultrastructural features in MGN and MPGN, and the activity of hepatitis B virus may be related to the development of HBV-associated glomerulopathy but further studies are recommended to confirm this relationship.
Locally advanced cervical carcinoma has shown high rate of local failure and poor survival rate despite the advances in modern radiation therapy techniques. Combination of chemotherapy and radiation therapy demonstrated benefit in improving local control and possibly the overall survival. Twelve patients with advanced stages (Figo stage III, IV) or 11b with bulky tumors (>5 cm in diameter) were treated with combination of radiation therapy and concurrent weekly cisplatin between May of 1988 and September of 1991 at Inje University Paik Hospital. Cisplatin was administered in bolus injections of 50 mg at weekly intervals during the courses of radiation therapy. Median follow-up period was 34 months with ranges from 3 to 53 months. Eleven patients were evaluable for the estimation of response. Response was noted in all the 11 patients: complete response (CR) in 7 ($64\%$), partial response (PR) in 4 ($36\%$). Of the 7 patients with CR, all maintained local control, whereas only 1 of 4 with PR showed local control. Six of 7 with CR are alive disease free on the completion of follow-up. Eight of 11 patients ($73\%$) maintained local control in the pelvis. The median survival for CR patient is 27 months and 9 months for the PR patients. Analysis of survival by stage shows 11 b 4/5, III 2/3 and IV 1/3. Overall survival rate was $61\%$. Three patients recurred: 1 at local, 1 in distant site and 1 with local and distant site. Toxicity for the combination therapy was not excessive. These results are preliminary, but definitely encouraging in view of markedly improved response rate compared with the results of historical control group.
We present a etrospective analysis of arterial embolectomies performed at the Inje University Seoul Paik Hospital. During the period of March 1987 Feburary 1996 twenty-six patients underwent embolectomies, eighteen patients were male and eight patients were female, mean age of patients was 56.8 years. Rest pain was the chief complaint in 24 patients, the remaining two patients complained of long term history of claudication after recovery of acute symtoms. But only 10 patients had sensBrylmotor symtoms. Heart was the most common source of embolization and frequent predisposing factor of embolism was ischemic heart disease in 8 cases and valvular heart disease in 11 cases. The sites of embolization were upper extremities artery in 6 cases, saddle embolism in 2 cases, lower extremities artery in 18 cases and the most common site of embolism was femoral artery in 1 1 cases. Preoperative angiography was taken in the diagnosis and planning of the embolectomy in 1) patients while in the other patient p eoperative angiography was not taken. Only two cases were operated within the golden period of 6 hours and other cases were operated in more than 6 hours after embolization. In all patients, the Fogarty embolectomy catheter was used without bypass surgery via bachial ateriotomy in the embolism of upper extremities artery, bilateral groin approaches in the saddle embolism and transfemoral approach in the embolism of lower extremities artery. However 3 patients were re-operated via transpopliteal approach in the distal poplitiotibial embolism. Eighteen patients received perioperative anticoagulation therapy by heparin or fraxiparine and wafarin was used in 17 patients at the time of discharge and the indication of anticogulation was patients of valvular heat disease andfor atrial fibrillation, peripheral artery atherosclerosis and recurrent embolism. Postoperative results of the embolectomy were as follows: fouteen pateints had excellent results, five cases had symtom improvement after re-operation, B. K. amputation in 1 case who had severe atherosclerosis of lower extremities, recurrent embolism in 1 case and death in 2 cases the cause of death were acute renal failure and cerebral artery embolism, respectively. The complications of the embolectomy were reperfusion syndrome, pseudoaneurysm and intimal dissection in one case each. Conclusively the problems of embolism is delayed diagnosis and increasing number of old aged patient who had suffered from ischemic heart diease. Preoperative angiography was not always needed for embol ectomy. Selective anticoagulation therapy can decrease incidence of re-embolism. In the distal poplitiotibial embolism, embolectomy of tibial artery was difficult.
Purpose : This study was performed to identify factors related to the resolution of primary vesicoureteral reflux (VUR) in infants. Methods : We reviewed 183 infants (M : F=149 : 34) diagnosed as urinary tract infection (UTI) between February 2002 and July 2007 at Sanggye Paik Hospital. The diagnosis of UTI was made by culture from a urine specimen obtained by suprapubic puncture (n=97), catheterization (n=83), or collection bag method (n=3, twice positive culture of same organism). All of the infants were performed renal ultrasonography, DMSA scan and voiding cystourethrography (VCUG) study. Follow-up imaging consisted of contrast VCUG or direct isotope VCUG at interval of 1 year. We evaluated the relationship of clinical and laboratory finding, radiologic finding in infants with VUR. Results : Among 51 VUR patients, 18 infants had grade I-II, 12 infants had grade III and the other 21 patients had grade IV-V. Abnormal findings including hydronephrosis on renal ultrasonography were not correlated with severity of VUR. However, the incidence of renal defect in the first DMSA scan showed a tendency of direct correlation with severity of VUR in female patients only (P<0.001). There was significant difference of resolution rate in three VUR groups (grade I-II, III, IV-V) in male patients only (P=0.025). Resolution rate was higher for male patients with unilateral VUR than bilateral (P<0.001). But unilaterality had not any affect on VUR resolution in female VUR patients (P=0.786). Resolution rate was higher for VUR patients without renal scar than VUR patients with renal scar (P<0.001). Conclusion : According to our findings, grade of VUR, laterality and renal scar are the factors that contribute to resolution of primary VUR in male and female infants differently.

Transpulmonary sequestration of leukocyte following cardiopulmonary bypass(CPB) has been recognized as one of main causes of postoperative pulmonary dysfunction. The purpose of this study is to investigate the effect of a single dose of prebypass corticosteroid on pulmonary leukostasis and postoperative pulmonary dysfunction. The study was performed prospectively in randomized-blind fas ion for 50 patients from January 1995 to June 1995. All patients were divided into two groups; In the steroid group(n=25), corticosteroid(Solu-Medrol 30mg1kg) was injected prior to CPB and in the placebo group (n=25), normal saline was injected before CPB. The results were summarized as follows. 1. Total peripheral leukocyte counts decreased significantly at 5 minutes of CPB in all patients(P<0.01), and began to increase progressively at later periods of CPB with neutrophilia. The significant rise remained at postoperative 7th day. 2. During partial CPB, transpulmonary leukostasis occurred in placebo group(P< 0.001), whereas it was prevented in steroid group. 3. In both groups, peripheral Lymphocyte counts were stable during CPB, but began to reduce at time of intensive care unit(ICV) and the Iymphocytopenia remained until postoperative )rd day. The Iympho- cyte counts recovered on postoperative 7th day. 4. In both groups, peripheral counts of monocyte were relatively stable in the e rly peroid of CPB, and increased gradually in the later periods of CPB. This significant monocytosis remained throughout postoperative periods(P< 0.05). 5. The mean value of postoperative PaOa was lower than that of pre-CPB In placebo group(P=0.01), but in steroid group, there was no significant difference(P=0. 90) and fever was higher in placebo group compared to steroid group(P=0.001).
