BACKGROUND: The pediatric CPR is rather uncommon practice than adult CPR in emergency room. Therefore, few interest and studies were focused in pediatric CPR. The object of this study is to make an analysis about pediatric CPR performed within hospital setting. METHOD: From January 1. 1990 to December 31. 1996, a total of 59 patients, less than 15-year-old, who received cardiopulmonary resuscitation were subject of this study. The study was done retrospective chart analysis for sex, age, weight, the place of cardiac arrest, initial EKG rhythms, endotracheal tube size, the causes of arrest, CPR time, ROSC, the amount and types of CPR drugs used during resuscitation. Wilcoxon rank sum test and chi2 test were used to compare the dose of drugs during CPR in each group. RESULTS: There were no statistical difference between ROSC and non-ROSC group in place of arrest, initial EKG rhythms, CPR time, dosage of CPR drugs. CONCLUSION: The uniform reporting guideline of pediatric advanced life support should be used for future pediatric CPR study, such as Utstein style guideline in pediatric CPR.

Cerebral CT findings were described in twenty-six cases with the late sequelae of acute carbon monoxidepoisoning and were compared with the neurological symptoms and signs. The CT findins include symmetricalperiventricular white matter low density in five cases, globus pallidus low denstiy in six cases, ventriculardilatation in seven cases, ventircular dilatation and sulci widening in three cases, and normal findings in tencases. Only one case showed low densities in both periventricular white matter and globus pallidus, Late sequelaeof the interval form of carbon monoxide poisoning were clinically categorized as cortical dysfunction,parkinsonian feature, and cerebellar dysfunction. The severity of the clinical symptoms and sings of neurologialsequelae is generally correlated with presence and multiplicity of abnormal brain CT findings. But CT. Anothercase showing small unilateral low density of globus pallidus had no parkinsonian feature but showed mild corticaldysfunction.

The metal ceramic crown is currently the most popular complete veneer restoration in dentistry, but in many cases, the metal cervical collar at the facial margin is unesthetic and unacceptable. Facial porcelain margin has been used in place of it. But this dose not solve the problems, such as dark gingival discoloration and cervical opaque reflection of porcelain veneer. Recently, metal copings which were designed to terminate its labio-cervical end on the axial walls coronal to the shoulder have been clinically used to solve the esthetic problem of metal ceramic crown. But in this design, porcelain veneer of labio-cervical area which is not supported by metal may not be able to resist the stress during cementation and mastication. The purpose of this study was to evaluate fracture strength and fractured appearance of crowns according to different coping designs. A resin maxillary left central incisor analogue was prepared for a metal ceramic crown, and metal dies were made with duplication mold. Metal copings were made and assigned to one of four groups based on facial framework designs: group 1, coping with 0.5mm metal collar; group 2, metal extended to the shoulder; group 3, metal extended to 1 mm coronal to the shoulder; group 4, metal extended to 2mm coronal to the shoulder. Copings and crowns were adjusted to be same size and thickness, and cemented to metal dies with zinc phosphate cement by finger pressure. Fracture strength was measured with Instron Universal Testing Machine. Metaldies were anchored in Three-way-vice at 3mm below finish line and at 130degree inclined to the lone axis of the crown. Load was directed lingually at 2mm below midincisal edge. Load value at initial crack and at catastrophic fracture was recorded. The results obtained were as follows: 1. Fracture strength values at initial crack were higher in groups 1, 2 than in groups 3, 4 but this difference was not statistically significant(P<0.05). 2. Conventional metal collared crown had greater catastrophic fracture strength than any other collarless crowns. 3. The greater the labial metal coping reduction, the lower the catastrophic fracture strength of crowns but when more than 1mm of labial metal reduction was done, the difference in strengths was not statistically significant(p<0.05). 4. The strongest collarless coping design was group 2.

Congenital melanocytic nevus(CMN) constitute a well-known risk factor in the development of malignant melanoma, but melanoma developing in newborn and infants are extremely rare. We describe a case of proliferating nodules within CMN at the age of 13 months. Like our case it is difficult to manage the proliferating lesions within CMN in infants. So we carefully suggest the indications of preventive excision when proliferating lesions occur within CMN as follows; 1) preventive excision is postponed until the age of two when the proliferating lesions are slowly growing, 2) surgical excision is needed when the lesions are rapidly growing exceeding 1 cm in size even though it is before the age of two.

Multiple endocrine neoplasi~a type 3 is a rare, heritable or sporadic, multiple neoplastic disorder that is charracterized by thyroid medullary careinoma, pheochromocytoma, multiple mucosal neuroma, and marfanoid habitus. The most important disorder of the syndrome is mucosal neuroma that is an early diagnostic sign of multiple endocrine neoplasia type 3. Early diagnosis of MEN type 3 determines prognosis of the disease. We present a case of multiple endocrine neoplasia type 3 of the sporadic pattern in a 27-year-old man who had typical medullary thyroid carcinoma, mucosal neuroma, marfanoid habitus, and megacolon.

19 cases of non-pineal intracranial germ cell tumors were reviewed retrospectively with both radiologic andclinical featurses. The results were as follows: 1. The age distribution was 8 to 32 year old (16 year old of meanage) and the sex distribution shows male predominence(15:4). 2. The histopathologic diagnosis included 11 cases ofgeminoma, 2 cases of mixed germ cell tumor, 1 case of embryonal cell carcinoma and 5 cases of unknown. 3. Thelocation of tumors was the suprasellar region in 8 cases, the left basal ganglia and thalamus in 5 cases, and theright frontal lobe in 1 case. Among 11 cases of geminoma, 6 cases involve the suprasellar region and 3 cases theleft basal ganglia and thalamus. 4. In clinical features, there were visual disturbance, diabetes insipidus,increased ICP signs, motor weakness, hormonal disorders, and personal changes in order. 5. In tumor marker studyof 6 cases of geminoma, 5 cases show increase in HCG, titie, but all 6 cases were normal in AFP titer. 6. In brainCT, most of all revealed well-defined homogeneous high density with or without small central low density andhomogenous enhancement at solid portion,and there was calcification in only case with mixed germ cell tumor.

Open fractures of the shaft of the tibia occur frequently because of the progression of industrialization, Different methods of treatment have been advocated as regards the care of the open wound and the method of stabilization of the fracture fragments. The reports, published until recently, have differed with respect to rates of morbidity and end results. With this in mind, we reviewed a consecutive series of 30 open fractures of the tibia at the Department of Orthopedic Surgery of the Eulji General Hospital between 1981 and 1983 by a variety of methods. The following results were obtained. 1. The highest incidence of fractures was encountered in 3rd decades(43.3%) and male to female ratio was 4: 1. 2. The most common cause of fractures was traffic accident(66.6%). 3. The most common anatomical level of fractures was middle third of the shaft(46.7%). 4. The severity of injury was classified according to the Ellis classification as follows. Minor group, 8 cases(40%), Moderate group, 8 cases(26.7%,), Major group, 10 cases(33.3%). 5. The most common associated injury was ipsilateral fibular fracture. 6. Of 30 cases, 11 patients(36.6%) had an open wound more than 5cm in length, 10(33.3%.) between 2.5 and Scm and 4(13.4%) below 2.5cm, and primary closure after thorough debridement and copious irrigation was done in 17 cases(56.7%). 7. Pin and plaster method was applied in 3 cases of minor group and 3 of moderate group, intramedullary nailing was applied in 9 of minor group and 5 of moderate group, and Hoffmann device was applied in 10 of major group. 8. The majority of cases(66.7%) were operated on within 1 week after injury, 9(30%) between 1 and 2 weeks and 1(3.3%) between 2 and 3 weeks. 9. The fractures in middle third of the shaft of the tibia treated with intramedullary nailing revea.ed the shortest healing time(average 13 weeks). 10. Complications such as delayed union, infection and disabled joint shiffness were encountered mainly in cases with severe soft tissue injuries.

The authors analyzed 30 patients whose celiac artery or its branches were dissected during the procedure of transcatheter arterial embolization (TAE) for hepatocellular carcinoma (HCC) and were followed up angiographically. The incidence of arterial dissection was 1.25%. The dissection occurred most frequently in the celiac artery (40% 12/30) and the proper hepatic artery(28% 7/30). The frequency of arterial dissection was affected by the status of the vessel and the experience of the operator. The follow-up angiography revealed complete recanalization in 40% (12/30), irregularity and narrowing of the lumen in 23% (7/30), pseudoaneurysm formation in 23%(7/30), and complete obstruction in 13% (4/30) of the cases. The rate of recanalization in the celiac artery was lower than that of any other arteries in our series. Recamalization to a certain degree without therapeutic intervention was observed in 72% of the dissected arteries enabling and contributing to subsequent successful TAE within 2 months in 78% of the patients with the dissection.

Extracorporeal life support (ECLS) has well demonstrated its efficacy in treating in-hospital cardiac arrest and is being used for broader indications. However, ECLS after prolonged cardiopulmonary resuscitation (CPR) has been traditionally contraindicated and is now challenging. Here, we introduce two cases of successful ECLS after prolonged CPR, resulting in a immediate and full recovery. Both these acute ST elevation myocardial infarction patients waiting for primary percutaneous coronary intervention (PCI) suddenly collapsed due to ventricular fibrillation (VF), which was refractory to conventional treatment. After 2 hours of conventional CPR, the ECLS had been implemented and primary PCI could be performed. Subsequent to successful revascularization, the VF was stopped with a single electric shock. In our second case, normal sinus rhythm was spontaneously restored after ECLS implementation, which was completed after 45 minutes of conventional resuscitation. Both patients made a full neurological recovery on the day of the event and were discharged with only minor complications.
