Paroxysmal nocturnal hemoglobinuria(PNH) is a rare, acquired disease involving multiple hematopoietic lines. Characteristics of PNH are intrinsic hemolytic anemia, iron deficiency anemia and venous thrombosis. report a case of PNH with characterostoc MR and CT findings. The signal intensity of renal cortex was lower than that of medulla on both T1- and T2- weighted MR imaging. On T2 weighted MR images, the liver showed very low signal intensity but the signal intensity of the spleen was normal. On precontrast CT the attenuation of renal cortex was higher than that of renal medulla and the attenuation of liver was higher than that of the spleen. These findings of MR imaging and CT were the result from the deposition of hemosiderin in the cells of proximal convoluted tubules and transfusional hemosiderosis of liver.

We examined the variations in the limbus-insertion distance, the width and the insertion shape of 260 horizontal recti muscles in 137 strabismic patients, and evaluated the relationship between insertion shape and postoperative results. The average limbus-insertion distance of medial rectus muscle was 4.72 +/- 0.49mm and that of lateral rectus muscle was 6.29 +/- 0.58mm. The width of medial rectus and lateral rectus mascle was 9.84 +/- 0.83mm and 9.57 +/- 0.84mm. The insertion shapes of horizontal rectus muscle were divided into 5 groups, straight, oblique type I and II, concave and convex patterns. According to insertion shape, insertion shape of the medial rectus muscle had no statistic difference in esotropia and exotropia(P=0.179), but in case of the lateral rectus muscle, it was staistically significant in both exotropia and esotropia(P=0.036). When the deviation angle was larger than 40 delta, the length of limbus width was statistically significant in lateral rectus muscle(P=0.018). The insertion shape divided into straight and non-straight pattern was statistically insignificant on postoperative success rate.

From December 1987 to September 1988, clinical evaluation were performed at the Yeungnam University Hospital on 138 patients with exudative pleural effusion comparing with biochemical, bacteriologic, cytologic and pathologic studies. The results were as follows 1. Among these 138 cases, Incidence of tuberculosis was 57.3%, neoplasm 26.8%. High tendency in malignant pleural effusion occurred in elder age. 2. In tuberculosis pleural effusion, the rate of positive smear and culture for acid-fast bacilli in the pleural fluid was 3.7% and positive biopsy for granuloma 75%. 3. In malignant pleural effusion, the rate of positive cytology for cancer cell in the fluid was 42% and positive biopsy 60%. 4. Analysis in tuberculosis and malignancy showed the tendency of high pH, WBC, protein and of low glucose, but there were clinically not significant in differentiating malignant pleural effusion from tuberculous pleural effusion. 5. Among 23 cases in which the pleural tissue findings were chronic nonspecific reaction pathologically, tuberculosis (52.2%), malignancy (26%), and idiopathic (21.8%) eventually in follow up studies.

The purpose of this study is to develop social medicine curriculum model and to propose its management device. The study developed the curriculum model and its management plan as follows; First, the social medicine curriculum can be implemented starting from the first semester of first year through the first semester of fourth year, and is splitted up into two semesters for each year of medical school. Second, a semester consists of sixteen weeks, giving two hours course per week. Third, the sixteen weeks curriculum should be composed of sub courses which lasts at least four weeks each. Forth, the elective course of social medicine is of four blocks in total, and runs from second semester of the second year through first semester of the fourth year. This means the elective courses in the first semester are opened to third and fourth year students. And the elective courses in the second semester are opened to second and third year medical students. Fifth, the minimum number of elective courses should be more than four courses per semester. Sixth, the credits for core and elective social medicine courses are one point each for any lectures or laboratories carried out in the following way; one hour course provided for sixteen weeks or two hours course provided for eight weeks. The social medicine education stands firm as one of the core subjects in twenty-first century medical education. Thus, the effectiveness and systematic development of the program as well as running it will be the most important criterion for determining the competency of a medical school.

Spontaneous gastric perforation is an important but rare cause of gastrointestinal perforation in neonates. Just over 200 cases have been reported in the literatures. In spite of recent surgical advances in its managements, mortality rate has been reported as high as 25~50%. Because of physiologic differences, immature immune mechanisms, variations in gastrointestinal flora and poor localization of perforation, a neonate with gastric perforation is at high risk. The pathogenesis is greatly debated. Five patients with spontaneous neonatal gastric perforation who were operated upon at the Department of Pediatric Surgery, Seoul National University Hospital from 1980 to 1993 were reviewed. Four patients were male and one female. The first indication of perforation was 1 day to 6 days of life. All of 5 perforations were located along the greater curvature of the stomach. The size of perforation ranged from 2 cm to 10 cm. Debridement and primary closure were performed in all patients. The operative mortality was 40%(2 of 5). The cause of perforation was not identified in all cases. Prematurity and necrotizing enterocolitis, synchronous or metachrotlous, were thought to be crucial prognostic factors. Earlier recognition and surgical intervention are necessary to reduce morbidity and mortality.

OBJECTIVE: The purpose of this study was to assess clinical characteristics of induction of labor group in nulliparous women at term with a single fetus in cephalic presentation. METHODS: we reviewed retrospectively the medical records of 73 nulliparous women delivered between August 2004 and July 2006. The patients were classified as induction of labor group and spontaneous onset of labor group to compare of obstetrical data. Student t-test, Chi-square, and Fisher's exact test were performed. RESULTS: Induction of labor group than spontaneous onset of labor group had higher < or =4 of Bishop score cervical status and time from admission to delivery was longer (p<0.05). The rate of cesarean delivery and meconium stained amniotic fluid were higher in induction of labor group (p<0.05). In case of Bishop score is higher than 4, normal vaginal delivery is higher than cesarean delivery (p=0.100). CONCLUSION: Induction of labor in nulliparous women is associated with low Bishop score and an increased risk of cesarean delivery. Success of vaginal delivery is tightly associated with favorable cervical status.

OBJECTIVE: To assess causative factors that may induce the leakage of the PMMA after the vertebroplasty performed on osteoporotic compression fracture patients. METHODS: Percutaneous vertebroplasty was done on 80 vertebral compression fractures in 54 patients from June.2001 to Nov.2002. Leakage of PMMA was divided into paravertebral, venous, epidural, and intradiscal leakage. The relationship between leakage of PMMA and various factors were analyzed such as clinical features, bone mineral density, existence of bone sclerosis, interval from injury to operation, amount of PMMA, tip location, operation method, compression pattern, compression ratio etc. RESULTS: Leakage was found in 39 vertebral bodies out of a total of 80 operated vertebral bodies. A large amount of PMMA, which was injected into compressed vertebra, induced a high incidence of leakage(P=0.042). Preoperative high bone mineral density in Compressed Vertebra induced a high incidence of leakage(P=0.014). The existence of sclerosis caused a high incidence of leakage.(P=0.014). Other factors, which were examined, did not induce the leakage of PMMA. CONCLUSION: Percutaneous vertebroplasty must be done carefully after a detailed examination of factors that might cause leakage of PMMA.

PURPOSE: The purposes of this study were to determine the abnormal high-resolution computed tomography(HRCT) findings of the lung in uncomplicated asthmatic children, to compare the clinical characteristics between normal and abnormal HRCT finding groups and to correlate abnormal HRCT findings with clinical characteristics, especially FEV1 and PC20. METHODS: Forty asthmatic children were studied. Inspiratory and expiratory HRCT scans were performed on all patients. Pulmonary function tests and methacholine challenge tests were done and total eosinophil counts and total IgE level were checked during the symptom-free period. According to the presence of abnormality in HRCT findings, the subjects were divided into two groups : Normal and abnormal HRCT finding group. Clinical characteristics, severity of asthma, FEV1 and PC20 were compared between the two groups. RESULTS: Abnormal HRCT findings were air trapping, fibrosis, bronchial dilatation, and bronchial wall thickening. Air trapping was the most prevalent finding(50%). Significant differences in total IgE level(P< 0.05), severity of asthma(P< 0.05), FEV1(P< 0.05) and PC20(P< 0.05) were found between patients with abnormal HRCT findings and those with normal HRCT findings. Air trapping scores were significantly correlated with FEV1(r=-0.469, P< 0.05) and PC20(r=-0.315, P< 0.05). CONCLUSION: Air trapping was detected in 50% of uncomplicated asthmatic children and air trapping scores were correlated well with the extent of airflow obstruction and the degree of airway hyperresponsiveness. Our data suggest that the extent of air trapping found on HRCT scans reflects the severity of asthma and airway hyperresponsiveness in asthmatic patients.
