It is notoriously difficult to obtain a sound bony union of congenital paeudarthrosis of tbe tibia with conventional methods. This paper is the results of using the free vascularized fibular graft for congenital pseudarthorsis of the tibia in 7 patients since 1978 in this hospital, which is the first attempt in Korea. During the follow-up periods from 9 months to 32 months, 5/7 patients(71%) had good or excellent bony union, 2 patients had bone resorption at tbe distal site of grafted bone and required a second supplementary cancellous bone graft with electrode insertion. So it is thought that the free vascularized fibular graft is one of good methods of treatment for congenital pseudarthrosis of the tibia.

An arteriovenous fistula may be defined as a vascular abnormality in which there are one or more direct or indirect communication between an artery and a vein without any intervening capillary bed. Largely, such fistulas are divided into two groups-acquired (traumatic) or congenital in origin. There is a general agreement that congenital A-V fistula results from a failure in differentiation of the common embryonic anlage into true artery and vein. The authors have experienced a case of congenital A-V fistula formed in the 4th finger of the left hand. Such fistula is very difficult to excise completely with the conventional method. But we have obtained the excellent result by utilizing advanced meticulous microsurgical technique in excision.

In view of the problems with infection, traditional orthopedic teaching has held that the use of metalic fixation in open fractures is contraindicated. But the bone shortening and internal fixation of amputated limb is a principle for replantation. The authors experienced 23 patients of replanted limbs including femur, tibia, humerus, radius and ulnar among total 142 replantations and also analysed them in the respect of the relationship among soft tissue injury, fixatives, bone union and infection rate from February, 1975 to July, 1981 in this department. The rate of delayed union, nonunion and infection were 22.6%, 6.5% and 25.8% respectively. It seems that the union process of bone in replanted limbs is similar to that of the open fracture and also rigid internal fixation is the most useful for bony union.

We present a case of meningeal and brain metastasis of multiple myeloma. A 60-year-old woman who had been diagnosed as multiple myeloma two years ago, was referred to neurosurgery department because of headache and nausea. The magnetic resonance image of the brain showed a large epidural mass and the parenchymal enhancement. The patient received an operation of tumor removal and cranioplasty. A histological diagnosis of metastatic multiple myeloma was made.

BACKGROUND: We could establish a streptonigrin-resistant strain called SR-1 strain from Staphylococcus aureus ATCC 6538 as a parental strain and characterize SR-1 strain as defective in the iron-uptake mechanisms including production of siderophores and expression of transferrin-binding protein on the cell wall. We performed this study to elucidate effect of the iron-uptake mechanisms on the growth in human body fluids. METHODS: Growth kinetics of SR-1 strain were compared with those of the parental strain and the increase of unsaturated iron-binding capacity (UIBC) was measured. Siderophore production and expression of transferrin-binding protein were detected by CAS diffusion assay and ligand-blot method probed with human transferrin conjugated horseradish peroxidase, respectively, as the strains were cultivated in normal pooled sera, ascitic fluid and pleural effusion. RESULTS: Siderophores activity in the body fluids could not be detected by the CAS diffusion assay. The parental strain expressed the transferrin-binding protein on the cell wall during the growth in ascites and pleural effusion except the sera whereas SR-1 strain did not. Growth kinetics showed that SR-1 strain grew sluggish compared to the parental strain. The peak of increase of UIBC of the parental strain was observed at the mid-exponential growth phase and the increase of UIBC of SR-1 strain was either lower than that of the parental strain or not changed. CONCLUSION: The iron-uptake mechanisms of S. aureus, especially expression of transferrin-binding protein, play a significant role in growing in the body fluids.

OBJECTIVES: To test the neurodevelopmental hypothesis of the schizophrenia, we compared MR brain scans of schizophrenic patients with headache patients. METHOD: We conducted 7mm-slice magnetic resonance imaging study to evaluate the prevalence of CSF in a sample of 28 headache patients and 23 schizophrenic patients. All subjects are right-handed person by Annett's questionaires. RESULTS: Any size CSF was fecund 13/23(56.5%)schizophrenics and 16/28(57.1%) of headache patients. But larger CSF was found 26.1% of schizophrenics and 10.7% of headache patients. No statistically significant difference in gender and clinical subtype. CONCLUSIONS: Higher incidence of CSF in schizophrenic patients supports the hypothesis that anomalous development of the brain is an important aspect of the schizophrenia.
