Adult Wilms' tumor unlike that of childhood, is a rare disease and there is controversy as to whether all these are indeed truly Wilms` tumor or in actually represent sarcomatoid renal carcinoma. The pathologic hallmarks of this neoplasm are distinctive and it is histologically similiar to the childhood tumor. The therapeutic guidelines that govern childhood Wilms` tumor should be applied to adult Wilms` tumor and prognosis is worse than that of childhood. A case of Wilms' tumor in 24 year-old female was presented.

PURPOSE: To establish the basis for a non-invasive and non-destructive assessment of the mechanical properties during natural fracture healing by analyzing the vibrational property of the fracture healing and comparing the vibrational property, the bone healing status (as determined by X-ray) and the mechanical strength parameters. MATERIALS AND METHODS: The tibial shafts of rabbits were broken under general anesthesia. The rabbits were sacrificed at 2, 4, 6 weeks after the fracture, then X-rays of the fractured tibias were sequentially taken to detect the fracture healing. The vibration mode and the biomechanical strength were measured. RESULTS: According to the results of a multiple regression analysis, the standardized coefficients of callus, apposition, lateral angulation, DAMP1, FREQ1 in the fractured tibias, were -0.80, -0.23, -0.21, -0.25, -0.25. In normal contralateral tibias, the standardized coefficients of the area, FREQ1, DAMP1, FREQ2, DAMP3 were -0.73, 0.28, 0.41, 0.39, -0.25. CONCLUSION: A monitoring of the fracture healing process that utilizes the frequency response function is thought to be useful in detecting the early phase of healing within 4 weeks. Additional studies on the vibrational characteristics of the healing bones after a clinical union or after simillar pathologies should be pursued so that future diagnostic applications ca be made.

Intramuscular lipomas are benign adipose tumors of the soft tissues that may resemble liposarcomas because of their size, deep location, and occasionally infiltrative growth. An awareness of their existence is fundamental to treating them correctly, and their differential diagnosis from liposarcoma is essential. Magnetic resonance imaging (MRI) is a useful diagnostic tool to differentiate benign adipose tumors from liposarcoma. Marginal excision and biopsy are required for the definite diagnosis and the treatment of symptomatic intramuscular lipomas. To the best of the authors’ knowledge, this is the first report in South Korea regarding the treatment of an intramuscular giant lipoma of the ankle.

While simultaneous bilateral partial nephrectomy with a conventional multiport robot has been consistently reported since the 2010s, the introduction of the DaVinci SP system (Intuitive Surgical, Sunnyvale, CA, USA) could provide a novel way to perform surgery on bilateral kidneys while innovatively reducing the number of incisions. In our first report worldwide, the patient with bilateral small renal mass (2.0 cm for the left and 1.5 cm for the right side) and preoperative normal renal function was placed in the lateral decubitus position on an inverted bed. After tilting the bed to be as horizontal as possible, a 4-cm incision was made in the lower part of the umbilicus for the floating trocar technique. The partial nephrectomy was performed reliably as with the conventional transperitoneal approach, and then the patient could be repositioned to the contralateral side for the same procedure, maintaining all trocars. Total operation time (skin to skin), total console time, and the left- and right-side warm ischemic times were 260, 164, 27, and 23 minutes, respectively, without applying the early declamping technique. The estimated blood loss was 200 mL. The serum creatinine right after the operation, on the first day, 3 days, and 90 days after surgery were 0.92, 0.77, 0.79, and 0.81 mg/dL, respectively. For 90 days after the procedure, no complications or radiologic recurrence were observed. Further clinical studies will reveal the advantages of using the DaVinci SP device for this procedure over traditional multiport surgery, maximizing the benefit of a single port-based approach.

We report very rare case of concurrent bronchial atresia and bronchogenic cyst. Morphologic apical segment of right upper lobe directly stemmed from right main bronchus. Bronchogenic cyst was communicating with atretic segmental bronchus and both were filled with mucus. The etiology is not well known, however it is likely that a single insult arround the 5th~6th week causes both malformations.

Cytogenetic techniques were used to detect specific chromosomal losses and / or stuctural changes in 6 meningioma cell population of 11meningioma patients. Polymorphic DNA markers were uti.lized to investigate the loss of constitutional heterozygosity on chromosomes 8. 17 and 22 in 9 meningioma cell population of 1l meningioma patients. As a result, 5 cases(M-2.4,5.9, and 10) represented 45. XX. -22 or 45, XY.-22 as stem line. In addition to chromosome 22, other chromosomes were lost randomly. In one case(M-3) normal karyotypic pattern was oberved. The 9q+ structural change was also noted in case M-2. This structural change was thought to be the chromosomal involvement secondary to the loss of chromosome 22 in meningioma. Retentions of constitutional heterozygosity on chromosomes 8 and 17 were found in all cases. Loss of constitutional hererozygosity on chromosome 22 were found at Hind m RFLP of v-sis in cases M-1 and M-7. EcoRI RFLP of v-sis in case M-1. Bgl II RFLP of v-sis case M-1. Xba I RFLP of v-sis in cases M-6. M-9 and M-11. And EcoRI RFLP of bcr in all cases. Rearrangement of chromosome 22 in case M-1 was detected on the Xba I RFLP of v-sis as extra band(3.14kb). The reduction to hemizygosity on chromosome 22 was one important step in tumorigenesis of meningioma. Monosomy 22 might operate at the primary level of tumor initiation. Random losses of other chromosomes or structural changes as 9q+ were postula!ed to be related to tumor development.

OBJECTIVE: To evaluate the efficacy of direct current electrical fields and peripheral external electrical stimulation to promote regeneration of the transected rat sciatic nerve. METHOD: Four groups were studied: three experimental groups and one control group. Cathod distal (CD) group; nerves were treated with 1.0 microampere direct current with the cathode oriented distally to the lesion, anode distal (AD) group; nerves were treated with the anode oriented distally to the lesion, external stimulation (ES) group; nerves were treated with 3 mA, 60 Hz, galvanic current, using a ring electrode at ankle joint 3 times per day. No current was delivered in control group. Electrophysiologic and functional assessments were conducted at 3 weeks postoperatively. RESULTS: All experimental groups showed significantly higher electrophysiologic and functional improvement than the control group. However, there is no significant differece in improvement among experimental groups. CONCLUSION: Both direct current electrical field and peripheral external electrical stimulation can effectively promote peripheral nerve regeneration.

PURPOSE: To evaluate the stability, activity level and clinical results of an autologous hamstring and Bone-patellar tendon-bone (BPTB) graft in an Anterior cruciate ligament (ACL) reconstruction. MATERIALS AND METHODS: Between September 1997 and January 2003, 22 patients with an ACL reconstruction with an autologous four strand hamstring tendon, and 30 patients with a BPTB autograft were enrolled in this study. At the time of the final follow-up, the patients were evaluated by stress radiographs using a Telos instrument, the Lysholm score, Tegner activity score, IKDC activity grades, and anterior kneeling pain. RESULTS: An evaluation of the anterior laxity using the Telos instrument revealed no significant difference in the hamstring and BPTB groups: side to side difference 2.6 mm in the hamstring group vs 2.3 mm in the BPTB groups (p>0.05). The Lysholm score improved from a preoperative score of 58 to a postoperative score of 88 in the hamstring groups and from 56 to 91 in the BPTB groups. The Tegner score for the hamstring groups was 2.4 preoperatively and 5.8 at the final follow up, and the Tegner score for the BPTB groups were 2.3 and 6.2 preoperatively and after the last follow-up, respectively. The Tegner score was similar in the two treatment groups (p>0.05). According to the IKDC rating system, 9% were normal and 64% were almost normal in the hamstring group. In the BPTB group, 10% were normal and 67% were almost normal. Anterior kneeling pain after a reconstruction with the hamstring tendon autograft (13%) was significantly less common than with the patellar tendon autograft (37%)(p<0.05). CONCLUSION: The hamstring autograft for an ACL reconstruction decreased the incidence of anterior kneeling pain and produced equivalent clinical results to the BPTB autograft.

PURPOSE: This study was performed to evaluate the clinical usefulness of femoral double tunnel PCL reconstruction using the tibial inlay technique. MATERIALS AND METHODS: From January 2001 to August 2002, 21 patients underwent femoral double tunnel PCL reconstruction using the tibial inlay technique and were followed for more than 21 months. The mean age was 37 years old (range 16 to 60 years old). The clinical results were evaluated with the Lysholm score and the Tegner activity score. Radiologic analysis was performed using the posterior stress and Telos stress views. RESULTS: The average preoperative Lysholm and Tegner activity scores were 46.0 and 2.3, respectively, and improved to 94.5 and 5.3, respectively, at the final follow-up. The average preoperative scores of the combined posterolateral ligament injury group was 40.6 and 1.5, which improved to 77.1 and 3.5 at the final follow-up. Preoperatively, two cases were grade II, 13 cases were grade III, 6 cases were grade IV, and posterior translation was an average of 14.6 mm. Postoperatively, 18 cases were grade I, 3 cases were grade II, and posterior translation was an average 2.9 mm. In a push view using the Telos device (15 kg) at 30o and 90o of knee flexion, there were no differences in posterior translation. Complications were limitation of flexion (3 cases), limitation of extension (1 case) and quadriceps atrophy (mean, 2.6 cm). CONCLUSION: It is suggested that femoral double tunnel PCL reconstruction with the tibial inlay technique using anterolateral and posteromedial bundles is an effective technique for the restoration of knee function, stability, and activity. However long-term evaluation of patients and comparisons with femoral single tunnel reconstruction are required to confirm the effectiveness of this procedure.
