BACKGROUND: The combination of Philadelphia chromosome (Ph) and monosomy 7(-7) was rarely observed in acute lymphoblastic leukemia (ALL). With the results from immunophenotyplc and molecular analysis, Philadelphia chromosome positive ALL with monosomy 7[Ph(+)/-7] has been considered that it may be derived from neoplastic transformation at the pluripotent stem cell level. We compared the clini-cal, laboratory, and hematological findings between 5 cases of Ph(+)/-7 and 5 cases of Ph(+) without monosomy 7 [Ph (+) /N7]. METHODS: During the period from January, 1995 to December, 1996, total 72 cases of ALL were confirmed among 259 cases of hematologic malignancy with bone marrow cytogenetic analysis. Among 72 ALL cases, 5 cases of Ph(+)/-7(monosomy 7 or 7q abnormalities) were compared with Ph only or Ph without monosomy 7(ph(+)/N7] on the hematological, immunophenotypic, other laboratory, clinical findings and event ree survival (EFS) The karyotyping of the bone marrow specimens was analysed byshort-term unsynchronized culture methods such as overnight colcemid treatment and 24 hours incubation following ethidium bromide treatment. RESULTS: The mean age of Ph(+)/-7 was 30.6+/-12.8 years, and it was significantly different from that of Ph(+)/N7 (p=0.009), Four cases of Ph(+)/-7 were classified as ALL L2 subtype, and 2 cases revealed CNS involvements. Immunophenotyping was positive in CD10, CDl9, CD2O, CD22 and HLA-DR. But one case revealed e-B-lymphoid lineage with positivity in CD34, CDl3, and CD33. The response to chemotherapy and EFS was very poor in Ph(+)/-7 group, and the mean EFS was 3.2+/-1.9 months(p=0.014). All of cases showed induction on failure in chemotherapy, relapsed with bone marrow, CNS and extramedullary involvements, and expired due to sepsis. CONCLUSIONS: Ph(+)/-7 ALL had very Poor clinical course with being resistant to chemotherapy and unfavorable prognosis, revealed L2 subtype by FAB classification, and was slightly older in ages compared with Ph(+)/N7 ALL.

PURPOSE: We evaluated the ability of endo-rectal coil MRI (ER-MRI) to predict the local pathological stage of prostate cancer prior to radical prostatectomy and compared the results with those of transrectal ultrasonography (TRUS). MATERIALS AND METHODS: ER-MRI using high field magnets (1.5 Tesla) were performed in 22 patients (mean age 62.8 years, range 51-73) with clinically localized prostate cancer before radical prostatectomy. Of the 22 patients, 17 patients were also assessed by TRUS. The results of the imaging techniques were compared with the post-operative histopathological findings. As one patient with pelvic lymph node metastasis, which was detected on frozen-section examination during surgery, was spared radical prostatectomy, the final evaluation included 21 patients. RESULTS: DSeven of the 21 patients (33%) were found to have extraprostatic extension (EPE), and 5 had seminal vesicle invasion (SVI). The sensitivity and specificity for diagnosing EPE using ER-MRI were 62.5% and 84.6%, respectively, and 16.7% and 100% with TRUS. The sensitivity and specificity for diagnosing SVI were 80.0% and 93.8%, respectively with ER-MRI, and 0% and 92.3% with TRUS. The accuracy of predicting SVI was 90.5% with ER-MRI compared to 70.6% with TRUS. CONCLUSIONS: ER-MRI was significantly better than TRUS for determining the local extent of prostatic cancer and for prediction of SVI in the preoperative staging of clinically localized prostate cancer.

Many methods of correcting secondary cleft lip nose deformity have been introduced, but a single best method that can be uniformly adjusted for all cases does not exist. Since it is difficult to make the nostril of the cleft side symmetric with that of normal side, the authors tried to formulate the basis for correction of unilateral secondary cleft lip nose deformity according to the varying amounts of deformed nostril. We then adopted 4 different methods of correcting the soft tissue and nostril deformity in 63 patients from 1996 to 1998 and surveyed the results. Our principles were as follows: 1) Alar rim incision was done in cases of different-shaped cleft-side nostrils with nearly the same measured area in comparison to the normal side. 2) When deformity of the alar-columellar web was severe, we performed modified Z-plasty. 3) When the nostril of the cleft-side nostril was smaller than the normal side with slight asymmetry, reverse W-plasty was done. 4) We adopted a reverse-U incision when there was a discrepancy in height with moderate asymmetry compared with the normal nostril. After dissection, repositioning of alar cartilage was done by same method in each case. A nasal stent was kept in position for at least 6 months postoperatively in almost all cases. After follow-up of 6 to 24 months, we concluded that our choice was correct in selecting the optimal operative method, considering the characteristics of deformity of the cleft side nostril in an effort to make it symmetric with that of the normal side.

Simple bone cyst is a benign bone tumor occurring most frequently in the long bone. The pathogenesis is not yet fully known and there is no established mode of optimal treatment. In 1979, Scaglietti reported favorable results in the treatment of simple bone cyst with steroid injection. We have studied 23 cases of curettage with bone graft and 13 cases of steroid injection in 39 cases of histologically proven simple bone cyst in the department Orthopedic Surgery at College of Medicine Yousei University dating from Jan, 1970 to Jan. 1989. In 1 case out of 23 cases, there was no improvement in curettage with bone graft, and this cases was treated with steroid injection. There were 4 cases which did not receive any treatment except cast immobilization. In this case, the patient refused further treatment. The mean follow up period was 20.1 months and the results and conclusions were as follows:1. The average age of patients was 17.9 years, and incidence under 20 years was 74.4% The male to female ratio was 1.6 to l. 2. Twenty three cases were treated with curettage with bone graft. The average age of patients was 16.1 years, and there were 4 cases of recurrence of simple bone cyst (17.3% ). 3. Thirteen cases were treated with steriod injection. The average age of patient was 12.1 years, and there was 1 case of recurrence of simple bone cyst(7.6%). There were 6 cases who were completely healed after one steroid injection, 3 cases after 3 injections, 1 case after 4 injection, and 3 cases who had a maximun of 5 injections. 4. The difference was statistically significant from equality (p<0.05). The steroid injection method is a more simple and a more safe procedure than curettage with bone graft, and can be done at the Out-Patient Department. Steroid injection may be repeated in persisting and recurrent simple bone cyst.

PURPOSE: To establish the incidence of deep vein thrombosis among Koreans after primary total hip arthroplasty and the usefulness of color doppler ultrasonography for routine noninvasive screening for deep vein thrombosis. MATERIALS AND METHODS: We performed prospective, randomized routine venography and color doppler ultrasonography before and after operation in a consecutive series of 89 primary total hip arthroplasty in which no form of prophylaxis was used. RESULTS: Of the 89 cases, eleven (12.4%) were found to have deep vein thrombosis (three proximal veins and eight distal veins) by bilateral venography. Most of the thromboses except two were asymptomatic. No patient had a symptomatic pulmonary embolism. Statistical analysis of risk factors, age, gender, weight, height, fixation method, and duration of operation time, were performed and there was no statistical difference (P>0.05). The reliability of color doppler ultrasonography for detection of deep vein thrombosis was demonstrated. CONCLUSIONS: We found insufficient evidence to recommend routine thromboprophylaxis in primary total hip arthroplasty among Koreans. The authors recommend that routine bilateral color doppler ultrasonography screening be considered after primary total hip arthroplasty for detection of deep vein thrombosis
