PURPOSE: To cmpare the clinical results of complex tibial plateau fractures treated by hybrid external fixation and dual plate fixation. MATERIALS AND METHODS: We studied forty patients with Schatzker type V and VI fractures respectively and selected twenty seven patients who were followed at least one year between January 2000 and December 2005. We evaluated the clinical results in which fourteen fractures with hybrid external fixation were compared with thirteen fractures with dual plate fixation. The clinical results were evaluated according to Knee Society Clinical Rating System and the statistical analysis was performed by Student t-test. RESULTS: There were no significant differences in terms of bone union time (average union time: dual plate fixation 13.8 weeks, hybrid external fixation 14.2 weeks). The quality of osseous reduction was superior in the fractures with dual plate fixation than those with hybrid external fixation. There were significant differences in functional score (average functional score: dual plate fixation 73, hybrid external fixation 62), but not in average knee score. CONCLUSION: The hybrid external fixation can be a useful modality for treatment of complex proximal tibial plateau fractures. But the good quality of the fracture reduction by dual plate fixation may be a indicator for favorable prognosis for satisfactory knee function.

Submacular hemorrhage from various causes induces the irreversible damage to the retina, leading to poor visual outcome. Surgery for removal of submacular hemorrhage was performed but the general results were not satisfactory in spite of better surgical technique. We took this study to identify the effectiveness and safety of intravitreal injection of tissue plasminogen activator(tPA) and SF6 for displacement of submacular hemorrahge. Thirteen patients who have submacular hemorrhage had undergone intravitreal injection of tPA and SF6 and positioned face down for about 1 week. Postoperative complication, best corrected visual acuity, final visual acuity, amount of displacement related to the duration of submacular hemorrhage and causal diseases were checked retrospectively. The average age of the patients was 64. Six eyes(46.2%) improved visual acuity by 2 lines or more, and 2 eyes(15.4%) lost visual acuity 2 lines or more. Complications included vitreous hemorrhage in 2 eyes, increased intraocular pressure in 2 eyes. Causes were trauma in 3 eyes and age-related macular degeneration in 10 eyes. The final visual results after 5 months or longer were related with macular lesion. Complete displacement was achieved in 10 eyes, partial displacement in 4 eyes at 1 month. The authors concluded that brief prone position after intravitreal injection of tPA and SF6 is rapid and effective method for displacement of submacular hemorrhage.

The endemic status of clonorchiasis and metagonimiasis along the Geum-gang (River) in Okcheon-gun (County) in Korea was examined. From February to December 2000, stools of total 1,081 inhabitants living in 5 villages were examined. Each stool specimen was examined by both the cellophane thick smear method and the formalin-ether sedimentation technique. Egg-positive cases were further analyzed by Stoll's egg-counting technique, and praziquantel was administered to positive cases. The egg-positive rates for Clonorchis sinensis and Metagonimus species were 9.3% and 5.5%, respectively, and the double infection rate was 3.5%. The numbers of eggs per gram (EPG) of feces of C. sinensis and Metagonimus sp. were 918 +/-1.463 and 711+/-947, respectively. The egg-positive rates for C. sinensis and Metagonimus sp. in the riverside area were 14.2% and 8.4%, respectively, which were significantly higher than those of the inland area (3.2% and 1.7%, respectively). The egg-positive rates of C. sinensis and Metagonimus sp. in males (16.7% and 10.0%) were significantly higher than those of females (3.5% and 1.8%). However, there were no significant differences of EPG values between localities and sexes. The prevalence of clonorchiasis and metagonimiasis in this survey was significantly lower than that in the previous reports. However, there is still a high prevalence of infection with C. sinensis and Metagonimus sp. in this region, especially in the riverside area.

Aneurysms of the coronary arteries are rare. They may be due to atheroselerosis, mucocutaneous lymph node syndrome, mycotic emboli, syphilis or trauma and occasionally they are congenital. The prognosis appears to be poor and death can occur suddenly from rupture of the aneurysm, peripheral coronary embolism or bacterial endocarditis. Recently surgical treatment has been successful. In a 5 year old patient with ventricular septal defect, two aneurysmal sacs located at the cardiac crux and just posterior to it was proved by coronary angiography and MRI, and successfully excised at operation.

Steatocystoma multiplex is a relatively rare condition characterized by multiple, small, yellowish, cystic nodules 2 to 4mm in diameter locatcd princioally on the upper arms and the thighs. This has a high familial tendency and probably has an autosomal dominant mode of transmission. These tumors of steatocystoma multiplex characteristically contain hair follicles and sebaceous glands, and are to be the dermoid cyst. There was a familial and congenital inferiority in the ectoderm in both patient and family, ie, ichthyosis, hypohidrosis, koilonychia, milia and comedones. A 26 year-old Korean soldier was seen in February of 1970. His condition started 10 years previously. The widespread cystic nodules were 0. 2 to 1 cm in size and yellowish in color, and located on chest, back, scrotum and behind both ear lobes. There was thickening and daky brownish discolorations of all finger and toe nails. His father and two brothers had similar disorders, HistoIogieally clusters of hairs, mainly of lanugo size but some of intermediate character, were found in the lumen.

We experienced a case of congenital goiter with congenital hypothyroidism in 45 day-old male, who complained of respiratory difficulty and anterior neck mass. After admission, he was diagnosed congenital hypothyroidism by the clinical manifestations and laboratory tests including biochemistry, radioimmunoassay, radioisotope study, perchlorate discharge test, and bone radiography. We obtained positive finding at the perchlorate discharge test and found that his congenital goiter with congenital hypothyroidism was manifested by organification defect. We started treatment with L-thyroxine orally at 6th hospital day. The case was presented with brief review of literatures.

Splenic anomalies are commonly associated with anomalies of cardiovascular system and of other organ systems. "Polysplenia" refers to the state in which the bulk of splenic tissue is divided into two and others more equal-sized splenic masses. We experienced a case of Polysplenia associated with complicated cardiovascular anomalies(Situs ambiguus, D-loop, normally related great arteries, interrupted inferior vena cave, bilateral superior vena cava, single atrium, common A-V canal, infundibular stenosis). We have presented this rare case and reviewed brief literatures.

To analyse the age of onset, etiologic microorganisms, clinical manifestations, managements and genetic variation of chromic granulomatous disease, the authors reviewed four patients who were diagnosed as CGD at Department of Pediatrics, Seoul National Univesity Children's Hospital. They were siblings in relationship-two of them were brothers, the others were brother-sister. @ES The results were as follows; 1) Initial manifestations developed within 1 year old, and lymphadenopathy associated with BCG vaccination was the most common. 2) In culture study of micro-organism, catalase positive microorganisms such as Staphylococcus aureus, Serratia marcescens, Coagulase (-) Staphylococcus, Enterococcus, Proleus vulgaris, Klebsiella pneumoniae, E. coli and fungus such as Candida albicans were isolated. In 2 cases, culture study revealed no growth. 3) Fever, lymphadenopathy, hepatomegaly, suppurative dermatitis and pneumonia were the most common manifestations. In most of cases, antituberculous medications were administered under the impression of tuberculosis without response. 4) Immunologic screening tests including B-cell system, T-cell system, and complement system were within normal limit except NBT test. 5) In spite of severe infections, NBT scores of all the cases were less than those of controls. Liver biopsies of 3 cases showed granuloma formation with characteristic yellow brown pigment-laden macrophages.
