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.

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.

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.

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.

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.

PURPOSE: A life-threatening hemorrhage resulting from a severe facial fracture is rare, but it needs a prompt and aggressive treatment. Especially, a massive oronasal bleeding combined with midfacial fracture which may result from the rupture of the internal maxillary artery. With the recent advances in the radiologic intervention, its use has increased for managing these life threatening case. We reviewed its usefulness with our experiences and literatures. METHODS: A retrospective review was performed to determine the usefulness of the transcatheter arterial embolization in patients with panfacial trauma. If the vital signs were unstable, cardiopulmonary resuscitation was performed. Oronasal bleeding was controlled with nasal packing and electrocautery. All injured regions were studied by radiologic study including CT. Even after primary management, if the oronasal bleeding was persistent, radiologic intervention was performed 10 patients were treated with transcatheter arterial embolization and the bleeding focus controlled by embolization with polyvinyl alcohol and gelfoam. RESULTS: After the intervention, the vital signs became stable and there were no complications from embolization in the follow-up for 6 months. Also patients could recover through appropriate operations. CONCLUSION: Transcatheter arterial embolization for maxillofacial injury has many advantages for both, the doctor and the patient. First, less pain is induced than a compression device or an operation, which is another way to treat oronasal bleeding. Second, it does not need general anesthesia. And through a single procedure not only we can know the accurate bleeding point, but we can also bleeding by embolization.

BACKGROUND: Lipoprotein(a) [Lp(a)] is an atherogenic lipoprotein that is assembled from a low density lipoprotein(LDL) and apolipoprotein(a) [apo(a)]. The variations in Lp(a) concentration tend to be inversely related to the number of kringle IV in apo(a) gene, but other polymorphisms [pentanucleotide(TTTTA) repeats, +93 C/T polymorphism, and Met/Thr polymorphism] of the apo(a) gene are also seems to be related to Lp(a) concentrations. The purpose of this study was to investigate the association of the pentanucleotide repeat polymorphism(PNRP) and Met/Thr polymorphism with the Lp(a) concentrations. METHODS: We studied 197 healthy adults. For genotype analysis of the PNRP and the Met/Thr polymorphism, PCR was performed. Apo(a) phenotyping was performed by SDS-PAGE and immunoblotting. The Lp(a) concentrations were measured by ELISA method. More than two groups were compared using the Kruskal Wallis one-way analysis test. To establish a relationship between gene polymorphisms and Lp(a) concentrations, The linear regression test was performed. RESULTS: Mean Lp(a) concentration was 25.3+/-21.5 mg/dL. Allele frequencies for PNRP, subjects with 8/8 genotype were 114(57.9%) and most frequently observed. The Lp(a) concentrations showed the tendency to decrease as the sum of alleles of PNR increased. Subjects with Met/Thr genotype were 119(60.4%), Met/Met genotype were 71(36.0%) and Thr/Thr genotype were 7(3.6%). CONCLUSIONS: For PNRP, subjects with 8/8 genotype were 114(57.9%) and 8/8 genotype was the most frequently observed. Met/Thr genotype was most frequently observed.
