The increasing use of intravenous polyethylene catheters has led to a growing incidence of accidental catheter breakage and migration of fragments into the central vascular system usually in the inferior vena cave, the right atrium, of the pulmonary artery. The most common complications were formation of a thrombus in the area of the foreign body, infection with endocarditis, and perforation of the heart. And so obviously the polyethylene catheter must be removed. In 1967, Massumi and Ross et al have been successful in removing a catheter fragment from the right atrum percutaneously with a snare device. With some modification as suggested by Curry, method of retrieving fragments of polyethylene catheters from the heart without chest surgery utilize wire snares or endoscopic forceps. This report describe the technique and its use in successfully managing these complications in four consecutive cases.

PURPOSE: Although the standard treatment of diaphyseal forearm fractures in children is conservative treatment with closed reduction and cast immobilization, unstable or irreducible fractures are usually needed by surgical intervention. The aim of this article is to determine the efficacy of the percutaneous transphyseal intramedullary K-wires fixation for the forearm diaphyseal fractures in children. MATERIALS AND METHODS: In this retrospective study, we reviewed 18 cases of forearm diaphyseal fractures in children, which were treated with percutaneous transphyseal intramedullary nailing using K-wires from January 2001 to December 2004. We analyzed the period for radiologic bone union and the complications until the last follow-up. RESULTS: The average period of follow-up was 15 months with mean age of 7.8 years. The average time to bone union was 6.2 weeks and nonunion, malunion, radio-ulnar synostosis and refracture were not found, just 2 local pin site infections were seen but healed by conservative treatment. Postoperative scar was small and the complications until the last follow-up were not found. CONCLUSION: In the operative treatment of the forearm diaphyseal fractures in children, we think percutaneous transphyseal intramedullary K-wire fixation is one of the effective methods because of the minimal invasiveness, simplicity and easiness in removal.

OBJECTIVES: The purpose of this study was to find the differences of temperamental characteristics of Korean children according to family environment and developmental history. METHODS: 1) The mothers whose children had been educated at twenty-five Samsung Child Care Centers nationwide participated in the survey using Parent Temperament Questionnaire for Children (PTQ) and the Child Development Questionnaire (CDQ). 2) The temperament of 1,175 children whose mothers completed PTQ were classified into 5 diagnostic clusters (Easy, Intermediate Low, Intermediate High, Difficult, Slow-To-Warm-Up) according to the method proposed by Fullard et al. 3) The results of classification were compared and analysed statistically according to each CDQ parameters. RESULTS: Statistically meaningful difference in the distribution of temperamental clusters were found in the CDQ parameters such as birth order of children, number of intimate friends, children's relationship with their peers, children's relationship with their siblings, children's relationship with their parents, type of milk feeding, motor development of children during 2 years after birth, motor development during from age 2 to 5, stranger anxiety, present health state of children, and relationship between parents. After all, the proportion of Easy type was greater in the children who were first-born, or who had good relationship with their peers or family, fast motor development, mild stranger anxiety, good health condition, or good relationship between each parent. CONCLUSION: This study shows that the distribution of temperamental cluster was significantly different in several parameters of family environment and developmental history of Korean children. The children with fast development, good interpersonal relationship or favorable family environment are more likely to be the Easy type.

OBJECTIVE: The study of 467 cases of amniocentesis have been done at the department of Genetics, Taegu Cheil Hospital from Oct. 1997 to May 1999 for the purpose of analysis of abnormal karyotype according to the indication and age distribution, METHODS: We collected amniotic fluid using 22G spinal needle and measured amniotic alphafetoprotein and acetylcholine esterase in supematant and performed cytogenetic analysis. RESULTS: Positive Down screeing(positive triple test) was the most common indication of amniocentesis (61.5%) and abnormal karyotypes were 24 cases(5.1%) in 467 cases. Among 24 abnormal cases, 10 cases(2.1%) of 21 trisomy were observed. Abnormal karyotypes were most common in the group of abnormal ultrasonogram finding and the gmup of maternal age between 31 to 35 years old, which consists of 25% and 7.7% respectively. CONCLUSION: More attention for the abnormal karyotype should be paid to the group of abnormal ultrasonogram finding and the group of maternal age between 31 to 35 years old as well as above 35 years old.

PURPOSE: To verify the changes of segmental motion after posterolateral lumbar fusion. MATERIALS AND METHODS: Thirty-eight cases of lumbar posterolateral fusion with good postoperative results and full range of motion, followed up for at least one year were reviewed. We measured the translation and angulation by the Dupuis method on flexion extension radiographs. RESULTS: 1) The motion at adjacent segments was 0.75 mm translation and 6.5 degree angulation at L1-2, 0.75 mm and 8.62 degree at L2-3, 0.95 mm and 9.67 degree at L3-4, 1.17 mm and 10.67 degree at L4-5 and 0.41 mm and 7.41 degree at L5-S1. The motion at L5-S1 was less than that in the control group, but at other levels it was not different. 2) The total range of motion of lumbar spine in the control group was 47.8 degree. In one-segment fusion the range of motion was 31.1 degree(64.9%), in two-segment fusion was 26.8 degree(56.1%) and in three-segment fusion was 14.3 degree(29.8%). The longer the fusion level was, the smaller the total range of motion of lumbar spine was. 3) The percentage of motion at adjacent mobile segments in the fusion group increased more significantly than that in the control group. CONCLUSIONS: Segmental motion at adjacent segment in the fusion group was similar to the motion in the control group. The compensatory increased motion at adjacent mobile segment was not definite, however, the percentage of motion at adjacent segment increased after spinal fusion.

OBJECTIVE: The purpose of this study was to evaluate the results obtained in patients who underwent staged 360-degree fusion with posterior fusion following anterolateral fusion for unstable thoracolumbar burst fractures. METHODS: The authors performed 360-degree fusion for thoracolumbar burst fractures in 21 patients between 2006 and 2010. We reviewed the medical records and follow-up data including pre- and postoperative neurological status, spinal canal compromise, segmental kyphotic angulations, complications, visual analogue scale (VAS) pain scores, and revision surgery rates. RESULTS: The mean computed tomography-measured preoperative spinal canal compromise was 55.9+/-20.7%. The segmental kyphotic deformity measured 20.2+/-4.4degrees preoperatively and had been corrected to 4.5+/-2.8degrees postoperatively. The mean vertebral body height loss of 57.4+/-6.9% improved significantly to 1.2+/-0.7% at the final follow-up examination. The mean preoperative VAS pain score of 8.2+/-0.8 improved to 1.5+/-0.6 at discharge. There were no cases of vascular complication, neurological deterioration, or revision surgery. CONCLUSION: Unstable burst fracture of thoracolumbar spine managed by staged posterior fusion and anterolateral interbody fusionis effective for kyphosis correction, significant canal decompression, pain reduction, maintaining stabilization and neurological improvement.
