Background: This retrospective review examines the preoperative condition, postoperative course, mortality and cause of death for the patients who underwent modified Blalock-Taussig shunt for complex congenital heart defects in early infancy. Material and Method: Fifty eight patients underwent modified Blalock-Taussig shunts from January 2000 to November 2003. The mean age at operation was $23.1\pm16.2$ days ($5\~81\;days$), and the mean body weight was $3.4\pm0.7\;kg\;(2.1\~4.3\;kg)$. Indications for surgery were pulmonary atresia with ventricular septal defect in 12 cases, pulmonary atresia with intact ventricular septum in 17, single ventricle (SV) in 18, and hypoplastic left heart syndrome (HLHS) in 11. Total anomalous pulmonary venous return (TAPVR) was associated with SV in 4 cases. Result: There were 11 ($19.0\%$) early, and 5 ($10.6\%$) late deaths. Causes of early death included low cardiac output in 9, arrhythmia in 1, and multiorgan failure in 1. Late deaths resulted from pneumonia in 2, hypoxia in 1, and sepsis in 1. Risk factors influencing mortality were preoperative pulmonary hypertension, metabolic acidosis, use of cardiopulmonary bypass, HLHS and TAPVR. Twenty four patients ($41.4\%$) had hemodynamic instability during the 48 postoperative-hours. Six patients underwent shunt revision for occlusion, and 1 shunt division for pulmonary overflow. Conclusion: Modified Blalock-Taussig shunt for complex congenital heart defects in early infancy had satisfactory results except in high risk groups. Many patients had early postoperative hemodynamic instability, which means that continuous close observation and management are mandatory in this period. Aggressive management may appear warranted based on understanding of hemodynamic changes for high risk groups.

Background: Minimally invasive technique for various cardiac surgeries has become widely accepted since it has been proven to have distinct advantages for the patients. We describe here the results of our experiences of minimal incision in cardiac surgery. Material and Method: From February 1997 to November 1998, we successfully performed 31 cases of minimally invasive cardiac surgery. Male and female ratio was 17:14, and the patients age ranged from 1 to 75 years. A left parasternal incision was used in 9 patients with single vessel coronary heart disease. A direct coronary bypass grafting was done under the condition of the beating heart without cardiopulmonary bypass support(MIDCAB). Among these, one was a case of a reoperation 1 week after the first operation due to a kinked mammary artery graft. A right parasternal incision was used in one case of a redo mitral valve replacement. Mini-sternotomy was used in the remaining 21 patients. The procedures were mitral valve replacement and tricuspid annuloplasty in 6 patients, mitral valve replacement 5, double valve replacement 2, aortic valve replacement 1, removal of left atrial myxoma 1, closure of atrial septal defect 2, repair of ventricular septal defect 2, and primary closure of r ght ventricular stab wound 1. The initial 5 cases underwent a T-shaped mini-sternotomy, however, we adopted an arrow-shaped ministernotomy in the remaining cases because it provided better exposure of the aortic root and stability of the sternum after a sternal wiring. Result: The operation time, the cardiopulmonary bypass time, the aorta cross-clamping time, the mechanical ventilation time, the amount of chest tube drainage until POD#1, the chest tube indwelling time, and the duration of intensive care unit staying were in an acceptable range. There were two surgical mortalities. One was due to a rupture of the aorta cannulation site after double valve replacement on POD#1 in the mini-sternotomy case, and the other was due to a sudden ventricular arrhythmia after MIDCAB on POD#2 in the parasternal incision case. Postoperative complications were observed in 2 cases in which a cerebral embolism developed on POD#2 after a mini-sternotomy in mitral valve replacement and wound hematoma developed after a right parasternal incision in a single coronary bypass grafting. Neither mortality nor complication was directly related to the incision technique itself. Conclusion: Minimally invasive surgery using parasternal or mini-sternotomy incision can be used in cardiac surgeries since it is as safe as the standard full sternotomy incisions.

The purpose of this study was to explore the care needs of family-caregivers caring for patients with a CVA and the level of self care of the patients. The subjects for the study were 112 patients with a CVA and their caregivers. These patients were seen in a hospital or out-patient-department(OPD) at two oriental medical hospital in Jeonbuk province. The survey instruments used in this study were Kang's ADL checklist for self care of patients and Kim's Likert-style checklist for care needs of family-caregivers to patient with CVA. The survey was conducted from July 4 to August 30, 1999. Internal validity by calculation of Cronbach's alpha was 0.95, which was regarded as high. The survey results were analyzed using the SPSS program, with percentages, means, t-test, ANOVA and Pearson's correlation coefficients. The results of this study are as follows : 1. The level of self care for patients with a CVA was : 1) complete dependence(M=14.9, 13.1%), 2) complete independence(M=23.6, 20.9%), 3) incomplete independence(M=23.9, 21.0%), 4) incomplete dependence(M=26.6, 25.0%), 5) dependence and independence(M=23.0, 20.0%). The items for which there was a high level of self care were : 1) drinking(M=3.62), 2) eating (M=3.25), 3) position returning(M=3.18) : and the items for which there was a low level of self care were : 1) ascending and descending stairs(M=2.08), 2) walking(M=2.47). 3) putting on and taking off trousers(M=2.55). 2. The mean score of the sum of the care needs of the family-caregivers was : 1) need for immediate care and help: 2) need of the way to communicate with patient: 3) need for education and assistance related to physical functional level: 4) need to be informed about the disease, treatment and care: 5) need for social support and consultation: 6) need for appreciation: 7) need for management of nursing problems related to immobility. The highest meed factor was the need for immediate care and help(M=3.47): and lowest need factor was the need for management of nursing problems related to immobility(M=2.80). 3. There were significant differences between the level of care need and general characteristic of the caregivers, there were family-caregivers age(P=0.001), marital status (P=0.276), occupation (P=0.006), monthly income(P=0.000), Patient's relationship to caregivers(P=0.004) and health(P=0.000). 4. There were significant differences between the level of self care and general characteristic of the patients, there were patient paralytic condition(P=0.01), blood pressure(P=0.01), and length of suffering(P=0.03). 5 There were significant differences between the level of care need and the general characteristic factors, which were CVA patient's blood pressure (P=0.05), problem of medical fee (P=0.05). 6. There was significantly correlation with the family-caregivers care need and the level of self care in the CVA patient(r=0.300, P=0.000). As a result, need to promote the level of self care in patients and to meet the care need of family-caregivers for more efficient nursing of CVA patients, is emphasized. Therefore more study is needed on an efficient way to provide rehabilitation and quality nursing interventions for family-caregivers and patients with CVA.

Purpose : Pseudomembranous colitis (PMC) occurs rarely in children, but its incidences are increasing due to frequent antibiotic use. We investigated the incidence and clinical characteristics of PMC accompanied by bacterial enteritis-like symptoms in children. Methods : Between November 2003 and July 2007 at the Department of Pediatrics, Dongsan Medical Center, we analyzed the medical records of consecutive patients who received antibiotics in the past 1 month, developed bacterial enteritis-like symptoms, and were diagnosed with PMC based on sigmoidoscopy examination and histological findings. Results : Among 22 patients who underwent sigmoidoscopy and biopsy examinations, 11 (50%) were diagnosed with PMC. These 11 patients were aged 2 months-12 years, among whom 5 patients (45.5%) were less than 1 year old. The clinical symptoms were bloody diarrhea (28.6%), abdominal pain or colic (28.6%), watery or mucoid diarrhea (23.8%), vomiting (9.5%), and fever (9.5%). The antibiotics used were penicillins (55.6%), macrolides (27.8%), cephalosporins (11.1%), and aminoglycosides (5.6%). The period of antibiotic use was 3-14 days. The interval between the initial antibiotic exposure and the onset of symptoms was 5-21 days. The results of stool examination of all patients were negative for Clostridium difficile toxin A. Patient distribution according to the degree of PMC was as follows: grade I, 18.2% (2 cases); grade II, 27.3% (3); grade III, 36.4% (4); and grade IV, 18.2% (2). PMC did not recur in any case.Conclusion : PMC is not a rare disease in children. If pediatric patients receiving antibiotics manifest symptoms like bacterial enteritis, PMC should be suspected. Endoscopy and biopsy should be applied as aggressive diagnostic approaches to detect this condition.

1. In order to increase our physical power through raising the amount of Hb to normal level and thus enrich our national power, it is earnestly required to improve the general eating habits in the direction of taking enough animal protein (nutrition food) that is required to form Hb and adequate administrative procedures of the nursery school are to be taken at the same time. 2. The genetic amentia's development of skeleton is generally under the normal level. And so their physical condition should be inferior to the standard growth rate of the same age. But the fact is that their physical growth is almost the same as the same age with only few exceptions. Besides, considering the fact that their amount of Hb is less than that of the normal level, I think we can conclude that the majority of the amentia in the nursery school were malnutrition during their prenatal period or during their infancy. We need continuous statistical study concerning many amentia that is scattered all part of our country, to make our amentia's hereditary transmission and the expression clear. And so the Intelligence Quotient of the amentia are from 26 to 80, we consider to need nourishing meal in ordinary times to make more efficient development of intellectual faculties. 3. As to the relation between blood type and disease, there are much debates going on in many countries. To get more apodictic results, however, continuous study is desired to be made in the future.

Occlusal stabilization appliance is one of the most common treatment option for management of temporomandibular disorders. It acts in oral cavity for several hours per day, and usually it will take at least 6 months to 2 years of total wearing periods to take a treatment goal. In the oral cavity, occlusal stabilization appliance, unintentional manner, is able to acts as a reservoir of bacteria and protect bacteria from saliva and oxygen. This condition is so favorable to many bacteria such as S. mutans and other anaerobes, usually have been reported as causative factors of dental caries, periodontal disease and oral malodor. In this study, we investigated anaerobic bacteria and S. mutans count before and after occlusal stabilization appliance use to evaluate the possible role of occlusal stabilization appliance as protector of these bacteria. Four men(average 27.5 years) wore maxillary occlusal stabilization appliance at each night(average 9 hours) for 5 days. we swabbed saliva-plaque mixed sample at 3 different site(maxillary left 2nd molar, maxillary left central incisor, mandibular left 2nd molar) before and after occlusal stabilization appliance use. Each samples were plated in (1) anaerobic blood agar medium, (2) selective S. mutans medium(MS-MUTV) and incubated in anaerobic chamber($CO^2$ 10%, $37^{\circ}C$) for 72 hours. Each bacterial colony forming unit(CFU) were counted with naked eyes. From obtained data, we can conclude as follows: 1. There was some changes about anaerobic bacteria and S. mutans count in oral cavity after occlusal stabilization appliance use. 2. The number of anaerobic bacteria was significantly increased at maxillary 2nd molar(P=0.003), maxillary central incisor(P=0.020) after occlusal stabilization appliance use compared with before. 3. Occlusal stabilization appliance use itself had indirect effect to increase the number of anaerobic bacteria at other uncovered opponent tooth site. 4. The number of S. mutans was significantly increased at maxillary 2nd molar(P=0.043), maxillary central incisor (P=0.049) after occlusal stabilization appliance use compared with before. 5. Occlusal stabilization appliance use itself had not any effect on the number of S. mutans at other uncovered opponent tooth site.

Purpose : Panax ginseng(PG) is considered to have salutary effects and stimulant actions on physical capacity. However, the effects of PG on the inflammatory cytokine secretion and hypoxia condition are still not understood. This study wasto elucidate the effect of PG on inflammatory cytokine secretion such as interleukin (IL)-1, IL-6, granulocyte macrophage colony stimulating factor (GM-CSF), and tumor necrosis factor $(TNF)-{\alpha}$. Also, the effects on the expression of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1 (HIF-1) were measured. Methods : The water extract of PG was administrated to HMC-1 cells before phorbol myristate acetate (PMA)+A23187 treatment. $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, GM-CSF, and VEGF secretion were measured by a modified enzyme-linked immunosorbent assay (ELISA). HIF-1 activation was measured by transcription factor enzyme-linked immunoassay (TF-EIA) Results : PG significantly decreased secretion of $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, and GM-CSF in PMA+A23187-induced HMC-1 cells. VEGF secretion was not changed but HIF-1 activation was decreased by the treatment of PG. Conclusions : PG inhibited the secretion of inflammatory cytokines, which impliesPG might contribute to treatment of mast cell-mediated inflammatory disease. Also, PG inhibited PMA+A23187-induced $HIF -1{\alpha}activation}$ and DNA-binding activity for HIF-1. Therefore, these data demonstrate that PG modulates inflammatory cytokines through inhibition of $HIF-1{\alpha}activation}$ activation.

Purpose: Since there are few studies involving acute pancreatitis in children, we reviewed our experience with this medical condition to describe the clinical features. Methods: A retrospective analysis was conducted by reviewing the medical records of 41 patients with AP who were admitted to the Department of Pediatrics of Pusan National University Hospital between January 1996 and June 2007. Results: Twenty males and 21 females (mean age, 8.7${\pm}$4.5 years) were included. In 22 patients (53.7%), no definitive causes were found. The most common etiologies were choledochal cysts (22.0%). Necrotizing pancreatitis was diagnosed in 5 patients (12.2%), and recurrent acute pancreatitis in 4 patients (9.8%). CT findings included pancreatic swelling (43.9%), peripancreatic fluid collection (29.3%), ascites (24.4%), and peripancreatic fat necrosis (12.2%). Serum amylase and lipase levels at diagnosis were 535.3${\pm}$553.2 and 766.2${\pm}$723.6 U/L, respectively, and were normalized within 1 week in 22 and 14 patients, respectively. On the basis of the Balthazar scale, 2 patients were diagnosed with severe AP. In 4 patients (9.8%), a surgical procedure was indicated. Major complications included ascites (32.3%), sepsis (16.1%), and pseudocyst and renal impairments (12.9%). Two patients died from multi-organ failure. Conclusion: The etiologies of AP in children are varied. Most children have a single episode and a self-limited course. However, AP of childhood still carries significant morbidity and mortality. Early diagnosis, appropriate treatment according to disease severity, and management of complications are important.

Introduction In order to improve medical education through the introduction of a concept of comprehensive health care of a community, an area surrounding the University Campus was chosen for the Community Health Service Project. It has been on operation for last 4 years with its major emphasis on family planning services, and maternal and child health care. The major objectives of this survey at the area are to obtain: 1) The demographic data, 2) The health need and trend of medical care, 3) The attitude and practice in maternity care to be used for further improvement of the planning and the services of the project. Population and Survey Method Out of three Dongs of the Community Health Service Area, only two Dongs namely Changchun and Yonhee were selected for the survey. Total number of households and population in the area studied was 3,683 and 21,857 respectively. An interview was performed with questionnaire schedule which was recorded by interviewers. This includes the degree of utilization of health services provided by the Community Health Service Program such as family planning, prenatal care during their last pregnancy, delivery history and complications of the delivery as well as the incidence of illnesses in general. Prior to the interview, all interviewers were trained for interviewing technique for two days. The survey was carried out during the period from October December 1967. Results 1) Demographic Data : 41.3% of the population studied were children under age 15 and only 3.5% were over 60 years of age. Crude birth rate and crude death rate of this area studied during the period of November 1966-October 1967 were 20.5 and 7.7 respectively. Infant mortality rate during the same period was 35.9. 50.4% of the 2,832 households fell into the category of middle class, 39.8% to the lower class and 9.5% to the upper class in economic condition. 19.8% of 2,832 householders had no formal education, 22.7% primary school, and 57.5% middle or higher school education. 2) Health Status and Utilization of the Community Health Service: Those who suffered from many illnesses during the month of October, 1967 were 690(4.6% of 14,891 persons). Classification of these patients into the type of disease shown respiratory diseases 27.4%, gastrointestinal diseases 18.1%, tuberculosis 10.9%, skin and genitourethral diseases 4.5% and gynecologic patients 4.5%. Only 55.9% of the patients received medical care at hospital or doctor's clinic. But among TB and gynecologic patients, 70.7% and 72.4% were treated at medical facilities. 10.6% of 2,832 householders interviewed has ever utilized the Community Health Service Program provided by the Yonsei Medical School, Classifying these clients into the type of service, 35.9% utilized the wellbaby clinic, 31.0% the family planning clinic, 14.7% the home delivery care, and the rest utilized other services such as the premarital guidance cinlic and the sanitary inspection service. 3) Maternity Care: 23.6% of 2,151 deliveries were done at medical facilities such as hospital, private clinic, while 76.4% were done at home. Acceptance rate of prenatal care was 32.6% as whole, but 49.6 of 774 women who had the prenatal care service had their deliveries at medical facility. 45.1% of total deliveries were attended by medical and or paramedical personnel. 75.8% of the deliveries of those received prenatal care were attended by medical and or paramedical personnel while only 27.8% of the deliveries of those who did not have prenatal care attended by medical and or paramedical personnel. 49.8% of deliveries of the upper class, 29.8% of the middle class and 9.9% of the lower class were attended by medical and or paramedical personnel. 6.2, 3.3% and 24.8% of mothers reported about their xeperience of edema, coma and fever during the period of trimester of pregnancy and puerperium. 4) Family Planning: The rate of practice of family planning was 27.9%. 31.7% of them were by IUD, 2.9% by oral pill, 15.2% by sterilization and the rest by traditional methods. Those women who had 3 to 4 children had highest(30.2%). Practice rate among the various methods of family planning, oral pill was the most popular method to whom had 2 or less children. In relation between the practicing rate of family planning and living standard, the upper, middle and lower class practiced 37.5, 29.4 and 19.9% respectively.

An explorative and descriptive study in order to determine the effect of family structure and other socio-demographic variables on health behavior, belief, locus, and value and utilization of public health service was carried out. Data were collected from 1,653 subjects randomly sampled in three areas, Seoul, Kyunggi province, and Cheju province. From Seoul 849 subjects were selected, 397 subjects Kyunggi, and 407 subjects from Cheju, respectively. Self-reporting questionaires were administered during the period from March to June, 1992. The major findings were as follows: 1) The subjects visited herb-doctor's at irregular intervals mainly to have tonic medicine prepared. They preferred herb-doctor's rather than with doctors at clinics and hospitals. Statistically significant difference was found among the regions studied (p<0.05). 2) The reason for visiting hospitals was primarily for treatment of diseases. They preferred hospital because they felt that the hospitals offer much highly reliable treatment services as well as medical accessibility. For the purpose of hospital utilization, statistically significant differences existed among sex, educational level, family type and region. However, no significance was found among sex, educational level, and region (p<0.05). 3) The subjects utilized general hospitals mainly for diagnosis and treatment of diseases. They preferred general hospitals because of their much better facilities and reliability. Statistical significance was found among sex, educational level, and region (p<0.05). 4) The subjects visited dentist at irregular intervals basis. They visited once half a year or three to four months. their purpose of visit was mainly for diagnosis and treatment of diseases. Statistical significance differences were found among educational level, region and economic standard (p<0.05). 5) Whenever their illnesses were mild and the pharmacies was located in nearby they visited to pharmacies. They visited once a month and patient medicines. Statistically significant differences were found among sex, educational level and region (p<0.05). 6) The subjects believed that herb medicine was quite efficacious for treatment of some diseases, particularly by information handed down through time-honored tradition and experience. However, they recognized that the efficacy of folk medicine can vary with type and severity of diseases. Statistical significance was among sex, educational level, region and economic standard (p<0.05). 7) The reason why subjects believed that pray and superstition are effective for treatment of certain type of diseases, particularly in neuropathy, was the belief in God's almighty. Statistically significant differences were found among sex, educational level, regions and economic standard (p<0.05). 8) Most of subjects under same condition preferred western medicine because they believed that it is more scientific and prompts in showing therapeutic effect. Statistical significance was not found in the choice of type of public health service among, regions. But significant differences were found among sex, educational level and region (p<0.05). 9) The subjects looked for pharmacy if they thought the symptom was mild. However, they visited hospitals for chronic disease and general hospitals for emergency treatment. Statistical significances were found among educational level, region and economic standard (p<0.05). 10) Although most of students wanted to have a healthy life as for the component of health standard and value, they think that they are not healthy (p<0.05). As for the health behavior, significant difference was found in the proportion of smoking and drinking between educational level and region (p<0.05). The health locus was affected by educational level, and health behavior was influenced by region, sex and educational level. The utilization of type of public health service was influenced by family type and region, and health belief by region and educational level, and the health values by region and economic standard respectively, most of correlation showed statistical significance. Among them, the highest correlation was seen between locus of control and external/internal locus of control, which is quite obvious. The correlation between health belief and behavior was the next highest, but still low (0.343). All the other variables are low but significant except only a few of those. These findings indicate that health education should be incorporated into the curriculum so as to develop desirable health habit, and ability of self-control in accordance with their growth stages. A systematic and scientific understanding on the herb/folk medicine is needed, and greater reliability of the utilization of public health services are is still required. Health policy for equal distribution of health service throughout the country along the hierarchical health service system and complementary mutual assistance and cooperation among various health organizations are also required.
