BACKGROUND: Peripheral blood stem cell transplantation in children has some difficulties compared with adult cases. Despite the children's total blood volume is small, they have a relatively higher volume of blood per weight than adults. Also, it is hard for the children to maintain 2 central vein during leukapheresis to shorten the time consumed. We compared the artery-harvest and central vein-harvested group for possible risk and stem cell yield in pediatric patients with malignancies. METHODS: From August, 1995 to January, 1997, 21 leukapheresis was performed by 7 patients. The patients who could have 2 central veins for leukapheresis were included in vein-harvested group and the patients who could have only 1 central vein were included in artery-harvested group. The peripheral vein was not used for leukapheresis. COBE Spectra(COBEBCT, Lakewood, CO) was used and priming was done by packed RBCs in patients weighing less than 20kg. Stem cell yield was assessed by MNC, CD34+, CFU-GM, respectively. During leukapheresis, the patients were closely monitored for change in vital sign, evidence for thrombosis, bleeding, hypocalcemia, etc. RESULTS: There was no serious complication in each group of patients. After the leukapheresis, WBC and platelet count decreased but Hb level was increased due to reinfusion of primed packed RBCs. Average flow rate was higher in vein-harvested group but there was no difference in time consumed and results in stem cell assay. CONCLUSION: Peripheral stem cell harvest in children by radial artery can be performed safely and easily without an increased risk or complication. In younger children, it is possible to achieve even more higher stem cell yield. If the patient is unable to maintain 2 central vein for leukapheresis, transient radial arterial catheterization is a safe and convenient method.

Fracture of the metal base of tihial components of total knee arthroplasty has heen occasionally reportecl. The most common cause of the failure of the metal hase plate was known to be a fatigue fracture around the screw hole where the strength of the metal hase plate was the weakest. We experienced a case of the fracture of the metal hase plate secondary to the t'racture of the posteromedial corner of the metal tihial condyle which was weakened due to the shoil peg hole for the base plate of MG II implant. Since the proximal portion of the posterior tihial condyle was normally thin, cutting the hone for the base plate made it thinner and wcaker than normal. Therefore stress fracture of the bone occurred and the overlying metal plate was subsequently hroken. From this experience. we concluded that the posterior peg hole may cause unwanted failure of the posteromedial corner of the tibial base plate.

The authors did clinical analysis for 37 cases, ranging from 5 to 13 year old of age and following result obtained. 1. In group I partial involved type had brightful prognosis even in the neglected the cases. 2. Ischeal brace did not give any help to group II & III but in group I, it gave some help to the prognosis. 3. In untreated cases of old age group developed early arthritic changes. 4. The inital radiological bony changes in early L-C-P. cases was the demineralization of the subchondral area and subsequently subohondral vaccum phenomena followed.

Three cases of Dupuytrens contracture which developed in hands were reported along with review of literatures. Partial fasciectomy was done as the choice of treatment for them to improve impairment of function of the hands. No attributable causes for the developement of the disease were found.

The authors did a clincal analysis of 95 cases of the osteomyelitis. Among them 72 were hematogenous in origin: 12 were secondary to open fracture: 6 were direct extension from adjascent soft tissue infection: 5 were complicated after open reduction of fracture, who were treated at Dept. of Orthopedics of Catholic Medical College for past 3 years from 1968 to 1971. Through this study following result were obtained: 1. Most of the patient were under age of 16 Years, In acute hematogenous osteomyelitis, over 80% of patient were under age of 12 years. Males were more frequently affected than females. 2. Generally, femur, tibia and humerus were most frequently affected than the others. In acute osteomyelitis, distal femur and proximal tibia were the most frequent site of involvement. 3. In acute osteomyelitis, early decompression, like drilling or fenestration operation gave more satisfactory result than the simple soft tissue drainage. Immediate surgical intervention with massive antibiotics administration is stressed without hesitation when diagnosis is made. The group treated within a week after onset gave relatively good result in this series. 4. Primary closure of the wound in acute osteomoelitis were considered not to be the good method which is usually adopted as procedure in the chronic type. 5. In the chronic osteomyelitis, continuous tube irrigation after saucerization was adopted when the bony defect is large. Primary closure of the wound were adopted in the case when surgical defect is small in size less than 4cm in diameter. 6. Treatment of the osteomyelitis complicated after open reduction of the fracture were generally treated with focal curettage and removal of fixative device when clinical union is evident, also fixative devices were out even in the group which were not united clinically but redisplacement is expected not to take place. In this group external support was given until fracture healing. Bony window was also made for drainage when cavitary change develped around the tip of nail.

Six cases of lunate dislocation were treated in the departments of orthopaedic surgery, Hangang Sacred Heart Hospital and Kangnam Sacred Heart Hospital, Hallym College during the period from March 1, 1978 to August 31, 1982. The results were as follows; l. Among the total 6 cases, two cases had lunate dislocation only and the other four had associated injuries of the same wrist joints. 2. Marupulative reduction was successful in only one case. Five cases were treated by open reduction, and for four of them internal fixation was tried. 3. Postoperative roentgenograms showed acceptable reductions in all cases except one which redislocation occurred. This case showed lunate dorsiflexion instability and was treated with extensor carpi radialis longus tenodesis. 4. The cases with pure lunate dislocation yielded better functional recovery than those with associated carpal injuries.

Supracondylar fracture is the most frequent injury of the elbow and frequently accompanies complications in children. Seventy two cases of supracondylar fractures have been treated and managed at Department of Orthopaedic Surgery, Catholic Medical College during the period from Jan. 1969 to Dec. 1972. The evaluation of fracture was done according to the classification of Holmberg and Hoyer. Among 72 cases of the supracondylar fracture, the most common type is 29 cases of Grade 2: (40.2%). Most cases were treated conservatively, and various method of treatment were adopted according to the condition of fracture. Residual angular deformities after successful manipulative reductiion can be accurately evaluated roentgenographically by the Baumanns method. Good results were obtained in 62.6%, fair results in 33.3%, and poor results in 4.1%. The incidence of cubitus varus deformity is 37.5%. There were no instance of ischemic contracture and no permanent neurological deficit in fracture cases.

A case of generalized primary amyloidosis with a reveiw of the literatures is reported. The 38 year old patient suffered from malabsorption syndrome for a year and was presented chronic renal failure with renal enlargment, myxedema and hemorrhagic gastritis. Biopsy of kidney and stomach revealed characteristic findings of amyloidosis by congo red stain and electronmicroscopy.
