Three cases of congenital coxa vara were treated by subtroch-anterie abduction osteotomy with percutaneous pin fixation of both fragments. The indications of the corrective subtrochanteric osteotomy for coxa vara deformity were the neck-shaft angle of 100 degress or less, the presence of marked gluteus medius limp and the vertical neck defect with progression of the varus deformity. Through a lateral approach, the lateral aspect of the proximal end to the femoral shaft was exposed and 2 Steinmann pins were inserted through the upper and lower levels to the proposed osteotomy. The distal pin was inserted perpendicular to the long axis of the femur and the proximal pin at an algle of desired correction to the distal pin and a subtrochanteric transverse osteotomy was completed. Two Steinmann pins were paralell to each other by adducting the proximal fragment and abducting the distal fragment. and the lateral cortex of the proximal fragment was impacted into the marrow cavity of the distal fragment. The Steinmann pins were then incorporated in the hip spica cast. The object of the operation was to correct the coxa vara, to change the stress on the vertical fissure in the neck from shear to compression and to overcome shortening of leg. With this technically simple method, the authors achieved adequate correction of the deformity. The ostetomies healed rapidly and the medullary canal was re-established in all cases, The gait of each patient was markedly improved and the Trendelenburg test become negative in all of them. One of these patients showed a mild recurrence of varus deformity and limp 2 years following surgery.

BACKGROUND: "Rebuild-up" phenomenon, induced by hyperventilation, is a characteristic finding on EEG in children with Moyamoya disease. Its mechanism, however, remains obscure. In this study, we examined the relationship between cerebral lesions on MRI, stenosis or occlusion of cerebral vessel on cerebral angiography, and EEG findings in children with Moyamoya disease. METHODS: We have reviewed medical records of 33 patients, who were confirmed as Moyamoya disease by cerebral angiography at Asan Medical Center. EEG and brain MRI were carried out in all subjects. RESULTS: 1) Epidemiologic data were : the male to female ratio was 1:1.1; highest rate(90.7%) of onset in age group below 10 years; mean age at clinical onset was 7.4 years; average diagnostic interval from clinical onset to diagnosis was 1.9 years. 2) The most common initial and recurrent or residual symptoms were motor deficit. 3) The most common site of occlusion or stenosis of cerebral vessel on cerebral angiography was anterior cerebral area(>97%) and the most common cerebral infarction area on brain MRI was anterior cerebral area, too. 4) The hyperventilation(for 3 minutes) on EEG were carried out in 25 patients and the prolonged build-up or rebuild-up phenomenon was observed in 13 patients(52%). 5) The prolonged build-up or rebuild-up phenomenon on EEG was observed in 6 of 15 patients who were occlusion of cerebral vessel, and in 7 of 10 patients who were stenosis of cerebral vessel on angiography. CONCLUSION: 1) The background slowings on EEG maybe suggestive of the infarction stage of Moyamoya disease in children. 2) The prolonged build-up or rebuild-up phenomenon might indicate the preinfarction stage of Moyamoya disease in children.

Epidemiological studies are important in both the prevention and treatment of mycobacterial infections. This study was initiated to establish the pulsed-field gel electrophoresis (PFGE) method, which are not yet extensively studied. The most apprpriate restriction endonucleases included Dral, AsnI, and XbaI. The optimal PFGE condition was different according to the enzymes used. Two stage PFGE was performed, in case of DraI first stage was performed with 10 seconds of initial pulse and 15 seconds of findA pulse, while the second stage was performed with 60 seconds of initial pulse and 70 seconds of final pu',se. The electrophoresis time for DraI-PFGE was 14 hours for each stage. Electrophoresis was performed for 22 hours, in case of XbaI, with 3 seconds of initial pulse and 12 seconds of final pulse. Electrophoresis was performed for 22 hours, in case of AsnI, with 5 seconds of initial pulse and 25 seconds of final pulse. In all cases the voltage of the electrophoresis was maintained constantly at 200 voltage. Standard mycobacterial strains, which included Mycobacterium bovis BCG, M. tuberculosis, and M. fortuitum, could not be differentiated by PFGE analysis. PFGE analysis was performed to differentiate 9 clinically isolated M. fortuitum strains using AsnI. All M. fortuitum strains showed different genotypes except 2 strains. Cluster analysis divided M. fortuitum strains into 2 large groups. PFGE analysis was performed to further differentiate M. fortuitum isolates using XbaI. The undifferentiated 2 M. fortuitum strains showed different PFGE patterns with Xba I. Cluster analysis of the XbaI-PFGE patterns showed more complex grouping than AsnI-PFGE patterns, which showed that XbaI-PFGE analysis was better than AsnI-PFGE in M. fortuitum genotyping. The top dissimilarity values of AsnI-PFGE and XbaI-PFGE were 0.74 and 0.75, respectively. This value was higher than that of arbitrarily primed polymerase chain reaction (AP-PCR) analysis and lower than that of restriction fragment length polymorphism (RFLP) analysis. This suggested that PFGE can be used as a supportive or alternative genotyping method to RFLP analysis.

The DNA fragment containing the phoA of Klebsiella pneumoniae was cloned into pACYC184. The size of the insert. was 4.0 kb and the restriction map showed it contained 3 Pstl sites and 4 PvuLI sites. The nucleotide sequence of the phoA region was determined, which showed strong (80%) sequence similarity with that of Escherichia coli. This suggested that these two species are phylogenetically very close to each other.
