Radical cystectomy is the most common and effective treatment modality for invasive bladder cancer. However, in case of the elderly patient its application accompanies anxieties over the possible mortality and complications. We purposed to analyze the postoperative mortality and early complication of the elderly patients compared to those of non-elderly patients. We reviewed retrospectively the medical records of 27 elderly patients, over 70 years of age and 61 non-elderly patients, under 69 years of age who were not at high risk anesthesiologically and underwent radical cystectomies with ileal conduits for invasive bladder cancers during last 11 years. We compared mortality, early complications, and postoperative hospital days between two groups. There was no death related to operation in elderly group, but one of the non-elderly group died of sepsis and DIC(disseminated intravascular coagulation) postoperatively Overall early complications were significantly higher in elderly group(P=0.013). But the major complications that were life threatening or required reoperation revealed no significant difference between two groups. There was no significant difference in postoperative hospital days(16.8 days in elderly group, 16.1 days in non-elderly group) between two groups. In conclusion, radical cystectomy can be performed as an effective and safe modality for the treatment of invasive bladder cancer even in elderly patients if only they are not at high risk anesthesiologically.

Morphometry of nuclei of the benign and malignant prostatic lesions was performed to study the relationship between nuclear size and shape and the prognosis of prostatic adenocarcinoma. Fifty one cases of prostatic adenocarcinoma and 13 cases of benign prostatic hyperplasia were included to evaluate area, perimeter, Dmax, Dmin, and 5 form factors of the nuclei by image analyzer (Zeiss Ibas 2000) using hematoxylin-eosin stained slides. All analytic factors of nuclear size and shape were significantly different between benign lesions and adenocarcinomas. Increased nuclear size was associated with nu- clear irregularity, presence of metastasis, advanced clinical stage, and high Gleason's grade and score of prostatic adenocarcinoma. On Kaplan-Meier method, survival was decreased with older age, no hormonal treatment, stage D, high Gleason's grade and stage as well as with larger size and irregular shape of the nuclei. In conclusion, morphometry of nuclei of the prostate can be a helpful tool to differentiate between benign and malignant lesions. Nuclear morphology is thought to be associated with prognosis of prostatic adenocarcinoma.

The current clinical technique for occlusal vertical dimension recording is based on marking the skin reference points on the patient's face and measuring between these pints using caliper-like device. And it is difficult to achieve reliable measurements by this technique because of movable soft tissue. The purpose of this study is to reveal the stability of skin reference points by comparing the relative movement between extra-oral skin reference points and intra-oral reference points using X-ray fluoroscope. 10 test subjects were divided into 2 groups : Group I (natural dentition) and Group II (denture-wearer whose vertical dimension was lost) and Group III consists of identical test subjects to Group II with their upper denture removed and record base inserted. Attaching the 3mm diameter steel ball to nose tip, chin and to existing denture (or record base), fluoroscopic examination and recording were taken during 2 jaw opening and closing movements. After subsequent digitization using personal compute, 1219 still pictures with 0.1 second interval were made. Using the 2 dimensional graphic software, measurements between reference points were executed. Dividing the entire jaw movement into 3 ranges (total, 1st half opening, 2nd half opening), rate of movement and relative movement between extra-oral and intra-oral reference points were calculated and statistically analyzed. The results of this study are as follows. 1. Within the same experimental group, no statistical difference was found in the stability of skin reference between lower lip point and chin point during total range of jaw opening and closing movement (p>.05). 2. In the first half range of jaw opening, statistical difference was found between Group I (natural dentition) and Group II (denture wearer) (p<.05). Group I has greater skin reference stability than Group II. 3. In the first half range of jaw opening, statistical difference was found between Group I and Group III (record base wearer) (p<.05). Group I has greater skin reference stability than Group III. 4. In the first half range of jaw opening, no statistical difference was found in the stability of skin reference between Group II and Group III (p>.05). 5. In the second half range of jaw opening, no statistical difference was found in the stability of skin reference between any experimental groups (p>.05). 6. In patients with their occlusal vertical dimension lost, employing other measuring references rather than skin is recommended because of low stability.

The Congenital Ulnar Drift of the fingers is a relatively uncommon and has symmetrical malformations of hand, face and foot characterized by MP joint flexion contracture and ulnarward deviation of the fingers and microstomia, In tarsal deformity, there are clubfoot and congenital vertical talus with rocker bottom deformity. In treatment, the report of the surgical treatment was rare. We experienced congenital ulnar drift of fingers in 2 patients in one family, which were treated by dome resection corrective osteotomy of the metacarpals. Therefore remarkable symptomatic improvement was obtained.

A 25 year old patient who had low back pain and sciatica was diagnosed as having a lumbar intraspinal extradural synovial cyst adjacent to a facet joint between the third and fourth lumbar vertebrae. The extradural defects defined with positive contrast myelography and postmyelographic computed tomographic scanning were posterolateral to the dural sac. Biopsy revealed the findings compatible with synovial cyst. Treatment consisted of laminectomy and surgical excision of the cyst.

Accurate anatomical reduction of the displaced acetabular fractures has a great clinical importance because acetabulum is related to weight-bearing and their fractures can lead to serious major sequelae. There are controversies and a lot of problems with regard to the management of the displaced acetabular fractures. The purpose of our study is to analyze the clinical results of operative treatment of the displaced acetabular fractures and to establish guidelines for treatment of their fractures. A clinical analysis was performed on 19 patients with displaced unstable acetabular fractures who had been operated on and followed for minimum 1 year period at Asan Medical Center from September 1989 to August 1992. The results were as follows: 1. The most common type was posterior wall fracture according to Letournel's classification. 2. Excellent or good results were obtained in 84% according to Goodwin's assessment method. All of the elementary fracture.s presented excellent or good results, while fair or poor results were observed in some T-shaped fractures or transverse and posterior wall fracture. 3. Complications were observed in 5 cases, including ectopic ossification(2 cases), traumatic arthritis(1 case), avascular necrosis of femoral head(1 case) and deep wound infection(1 case). Those seemed to be related with severe acetabular injury and extensive approach. 4. Kocher-Langenbeck approach was satisfactory for reduction and fixation of posterior column in transverse fracture, while extended iliofemoral approach was necessary for fixation of both column in T-shaped fracture. 5. Reduction of fracture of ilium was prerequisite for reduction of acetabular articular surface. 6. In displaced unstable acetabular fractures, early surgical intervention shich includes accurate anatomical reduction, and rigid internal fixation should be undertaken, and early joint motion should be followed to restore the joint function and to decrease the complication rate.
