Primary pyogenic psoas abscess is rare lesion, and often is not suspected. Reasons for delayed diagnosis are unfamility with the lesion and the fact that symptoms often resemble those of primary disease of the hip. We present a case of primary pyogenic psoas abscess in child, which was diagnosed by MRI, and completely recovered after surgical treatment.

Fracture healing in the hand is not an isolated goal. The functional end result is of paramount importance. When the correct techniques are used, miniplate fixation for metacarpal and phalangeal fractures of the hand provides rigid internal fixation, stabilizes the skeleton, preserves the gliding tissue, and therefore allowing immediate active range of motion exercise as well as minimizing joint and tendon complications. The authors have reviewed 39 patients, 52 cases of metacarpal and phalangeal fractures of the hand which were treated with miniplate in the department of orthopaedic surgery, Chang Ang Gil hospital from Sep. 1989 to Feb. 1993. The following results were obtained. 1. Miniplate fixation, in terms of fracture reduction and maintenance, allows on accurate anatomic reduction with rigid fixation which in turn affords on early mobilization without loss of reduction alignment. 2. The roentgenographic union was obtained within 15.1 weeks in average. The mean total acitve motion at the fractured finger was 230°. The complication rate was 11.5%. 3. In the treatment of metacarpal and phalangeal fractures of the hand, especially fractures of metacarpal bones, fixation with miniplate is considered to be an useful method in terms of getting fracture union and good range of motion with relative low complication rates.

OBJECTIVE: This study was performed to evaluate the effect of cervical cerclage and the clinical characteristics in incompetent internal os of the cervix (IIOC). METHODS: A study was conducted on 170 patients with IIOC, 199 cases of IIOC were admitted and treated with McDonald operation or modified Shirodkar operation at department of Obstetrics and Gynecology Il Sin Christian Hospital from January 1. 1994 to December 31. 1998, of this 14 cases were follow up lost, so 185 cases were analyzed. RESULTS: 1) The incidence of IIOC was 0.43%, 1 in 233 deliveries. 2) The mean age of IIOC patients was 30.54yrs old and the most frequent age group was in 30-34yrs old group (43.78%). 3) The average number of gravida and parity before operation were 4.71 and 1.62. & the success rate of operation was low at high gravida & parity. 4) The predisposing factor was previous history of dilation & curettage (43.75%), Cx. laceration after delivery (6.49%), midtrimester termination (4.32%) etc. 5) The operation methods were McDonald operation (91.35%) and modified Shirodkar operation (8.65%) & the success rate of McDonald operation and modified Shirodkar operation were 85.80% and 87.50%. 6) The successful fetal salvage rate was 85.95% and the highest success rate was 87.50% in 14-16 weeks of gestation group. 7) The more cervix dilate, the more failure occurred. 8) The causes of operation failure were premature rupture of membrane (50.00%), preterm labor (34.62%), FDIU, anomaly, APH etc. 9) The delivery methods after operation were vaginal delivery (65.54%), cesarean delivery (34.46%). CONCLUSION: The 14-16th weeks of gestation group & no cervical dilatation have higher success rate indicating that early diagnosis and appropriate timing of operation is associated with a greater operation success rate.

To observe the anesthetic characteristics of two different speeds of injection using 0.5% plain bupivacaine during spinal anesthesia, 40 patients undergoing lower extremity surgery were allocated randomly into two groups. In one group, 3 ml of 0.596 plain bupivacaine was administered into the subarachnoid space using 25 gauge Quincke spinal needle to the patients with a lateral horizontal position at duration of 10 seconds. In the other group, the duration was 180 seconds. There were no statistically significant differences between two groups in maximal level and its onset time of sensory blockade, hemodynamic changes, onset time to grade 3 Bromage motor blockade. We concluded that the speed of injection does not affect the anesthetic characteristics of spinal anesthesia using 0.5% plain bupivacaine.

Bone graft using growth factors and guided tissue regeneration have been used for the regeneration of infrabony defects which caused by periodontal disease. Calcium sulfate which is one of the resorbable barrier materials used for guided tissue regeneration. Platelet rich plasma which is a easy method to obtain the growth factors had many common points but, platelet rich plasma was still studying. This study was the comparative study between bone graft using platelet rich plasma and guided tissue regeneration using calcium sulfate barrier material in clinical view. For the study, 28 sites(2 or 3 wall infrabony defects) were treated. 14 infrabony defects were received surgical implantation of BBP-calcium sulfate composite with a calcium sulfate barrier and the others received BBP mixed with platelet rich plasma. Clinical outcome was accessed 3 and 6 months of postsurgery. 1. There was no statistical difference between CS group and PRP group in pocket depth, gingival recession, clinical attachment level, and probing bone level at baseline. 2. was statistically significant reduction in probing depth, clinical attachment level, and probing bone level at 3 and 6 months postsurgery(p<0.05). 3. In the probing depth and clincial attachment level PPR group had less improvement than CS group, but there was no statistically difference at 3 and 6 months postsurgery. 4. In the recession PPR group had less recession than CS group, but there was no statistically difference at 3 and 6 months postsurgery. 5. In the probing bone level PPR group had less improvement than CS group, but there was no statistically difference at 6 months postsurgery. In conclusion bone graft using platelet rich plasma and guided tissue regeneration using calcium sulfate barrier showed similar clinical improvement for the treatment of 2 or 3 wall infrabony defects.

PURPOSE: The purpose of the present study is to determine the relation between in vitro resistance to 9 drugs, measured with colorimetric methylthiazol tetrazolium(MTT) assay and prognostic factors. METHODS: Thirty children with leukemia were evaluated at the pediatric department of Dongsan Medical Center. All samples tested with the MTT assay contained 80% or more leukemic cells, which were isolated by Ficoll density gradient centrifugation, and were incubated with 9 drugs for 4 days. The optical density(OD) of the wells was measured with microplate spectrophotometer. Leukemic cell survival(LCS) was calculated by OD treated well/OD control wellsx100(%). LD50 was calculated from the dose-response curve and used as a measure of resistance. RESULTS: Among the 30 children with leukemia, 16 were ALL, 14 were AML. Seventeen boys and thirteen girls ranged in age from 9 months to 16 years. Comparing LD50 values according to leukemic type, AML revealed relatively high LD50 values for all drugs, except VCR. But there were no significant differences between ALL and AML(P>0.05). Male showed high LD50 values for ASP, DET, ARA-C, VP16, ADR and 6TG. Age<2 and >10 years children showed high LD50 values for all drugs, except 6TG. Patients with a leukocyte count>100,000/mm3 at diagnosis showed high LD50 values for VCR, ASP, DET, MTX, ARA-C, ADR, and 6TG. Patients with normal chromosome showed higher LD50 values. CONCLUSION: Our study showed higher LD50 values at AML, male, age<2 and 10>years old, leukocyte count>100,000/mm3, and normal karyotype. The MTT test may contribute to the selection of effective chemotherapeutic agent for children with acute leukemia.
