Distal radioulnar is a part which has a rotational movement through the function of distal radioulnar joint and extensor carpi ulnaris. The injury mechanism in this area is usually a trauma largely due to traffic accidents. In general these injuries to the distal radioulnar joint are treated by a closed reduction. However, the isolated distal ulnar fracture without radial fracture, which is often called the night stick fracture, is difficult to treat by a closed reduction and a cast immobilization alone, especially if there is a displacement or fracture segment impinging soft tissue or severe comminution. Nonunion has been the frequent outcome with this method of treatment and limitation of rotation of forearm and distal radioulnar joint have occurred due to long period of immobilization or malunion. Thus, a different treatment modality such as open reduction and internal fixation and early active joint motion has arisen as a better treatment modality. In this study, 8 cases of isolated distal ulnar fracture without radial fracture have recieved the operation and the early active joint movement, if a displacement was present either at the time of injury or after the initial closed reduction. As a result, this method has enabled the patients to reduce the rate of complication of nonunion and to recover limitation of joint motion in a shorter time period.

BACKGROUND: Hydration, the water content of the stratum corneum, is an important factor in both the appearance and the barrier function of the skin. Many non-invasive methods have been developed in order to assesa the hydration state of the skin and the effect of various moisturizers. The hydrometer and carneometer are commercially available instruments which are widely used in dermatologic research. OBJECTIVE: Our purpose was to compare the measuring usefulnes of both instruments on normal subjects with a wide range of hydration states of the hornylayer. METHODS: We measured the conductance with the hydrometer and the capacitance with the corneometer in various hydrating eonditions and compared both insruments. RESULTS: Conductance had a non linear correlation with capacita ice. Capacitance measured with the corneometer had a high sensitivity to moisture in a wide range of hydration levels. On the other hand, conductance guaged with the hydrometer showed a few sensitivity to moisture at a low level. When the hydretion level was measured after a moiturizer was added, 10 % urea cream showed a sharp increase by 256% in terms of conductanae, and H-base by 97.8%. Mineral oil decreased by 41.5% and petrolatum by 62% respectively. On the other hand, when measured in terms of capacitance under the same conditions as above, 38.9 increase in 10% urea cream, 19.3% increase in H-base, 20% decrease in mineral oil, and 43.5 % decrease in petrolatum were reported. Conductance showed a higher hygroscopicity and a lower water holding capacity than capacitance did. When the measurement of the moisture level iri virious parts of the human body is performed, the corneometer provided us with more stable alies than the hydrometer. While the hydrometer can not the available and appropriate under the condition of insulation, the corneometer can measure moisture levels even down at the depth of 250mm. When measured after the oily surface of the forehead was cleansed with soft tissue, conductance and capacitance revealed higher values of moisture levels than before the eleanin. However, there is no statistical significance in these values. CONCLUSION: The hydrometer is a more appropriate tool for the measurement of moisture at a high level, and the corneometer at a low moisture level. The hydrcmeter is a more sensitive method of measuring the increase and the decrease in the moisture level.

PURPOSE: To investigate the levels of radiation exposure of an operator which may be influenced by the wearing an apron, type of procedure, duration of fluoroscopy and operator's skill during various interventional procedures MATERIALS AND METHODS: Radiation doses were measured both inside and outside the apron(0.5mm lead equivalent) of the operator by a film badge monitoring method and the duration of fluoroscopy was measured in 96 procedures prospectively. The procedures were 30 transcatheter arterial embolizations (TAE), 25 percutaneous transhepatic biliary drainages (PTBD), 16 stone removals (SR), 15 percutaneous needle aspirations (PCNA) and 10 percutaneous nephrostomies(PCN). To assess the difference of exposure by the operator's skill, the procedures of TAE and PTBD were done separately by groups of staffs and residents. RESULTS: Average protective effect of the apron was 72.8%. Average radiation exposure(unit:micro Sv/procedure) was 23.3 in PTBD by residents, 10.0 in PTBD by staffs, 10.0 in SR, 8.7 in TAE by residents, 7.3 in TAE by staffs, 9.0 in PCN and 6.0 in PCNA. Average radiation exposure of residents were 1.9 times greater than those of staffs. CONCLUSION: Radiation exposure was not proportionally related to the duration of fiuoroscopy, but influenced by wearing an apron, various types o[procedure and operator's skills.

Wegener's granulomatosis is a disease of unknown etiology that is characterized by the clinicopathologic complex of necrotixing granulomatous vasculitis of the upper and lower respiratory tract, glomerulonephritis, and variable degrees of small vessel vasculitis. Recently Antineutrophil Cytoplasmic Antibody (ANCA) has been reported to be a highly specific test for the diagnosis of Wegener's granulomatosis. We have experienced a patient of Wegener's granulomatosis in a 11 year old girl who was admitted with complaints f arthralgia, hematuria, convulsion and associated with otitis media and sinusitis. Serologic test of C-ANCA was positive and histologic findings of the kidney showed crescentic glomerulonephritis with sclerosis and surrounding infiltration of multinucleated giant cells. Patient was treated with pulse methylprednisolone without improvement. The clinical course progressed rapidly and expired due to the renal failure, gastrointestinal bleeding and status epilepticus. A brief review of literatures was made.

The authors report two cases of recurrent transitional cell carcinoma at the anastomotic site of the ileal conduit and ureter after total cystectomy. In one patient, a recurrent tumor was also found in the distal ureter which had not been removed during previous nephrectomy. At follow up, the patients presented with gross hematuria or hydronephrosis, and the presence of mass lesions was demonstrated by intravenous urography,antegrade pyelography, and/or loopography. Transitional cell carcinoma was diagnosed by surgery and pathologic examination.

There have long been a lot of controversies on the treatment of unstable thoracolumbar spine fracture, and the role of decompression is also controversial. Compression of the neural elements by retropulsed bone fragments can be relieved indirectly by the reduction with posterior instrumentation or directly by the exploration of the spinal canal through a posterolateral or anterior approach. There is no universal agreement about the indications for each of these method. Authors analyzed the result of 24 cases of thoracolumbar spine fracture which had been operated by anterior decompression and Kaneda instrumentation from the February 1990 to May 1993 at Inha general hospital. The results were as follows: 1. The most common cause of injury was falling from a height, 20 cases (83.3%). And the 12 cases were in the 4th decade, with an average age of 37.7 years. 2. According to McAfee classification, there were 7 stable(29.2%) and 15 unstable bursting fractures(62.5%). And the most common level of injury was L1(11 cases, 45.8%). 3. Neurologic status was improved one or more grade(Frankel grade) in 21 cases except one case of complete paraplegia. 4. The average correctional angle of kyphotic deformity was 13.1° immediate postoperatively, and the loss of correction(average, 6.7°) was observed during the follow-up period. 5. The segmental instability was found at the level below the fusion in three cases during the follow-up period. 6. There was neither failure of instrument, dislodgement of graft bone nor lateral wedging during the follow-up period.

The spinal fusion is used for correcting malformations, stabilizing unstable segments, and suppressing the progression of disease, but it causes more load on the adjacent segment and as a result, the degenerative changes accelerate. Furthermore, the accelerated changes case spinal stenosis, degradation of nucleus pulposus, degenerative spondylolisthesis, acquired isthmus defect, and arthritis of articular facet, it rarely needs surgical treatment. The purpose of this study is to know the effect of the fusion level and range on the adjacent segment, to be a standard for determining the fusion range prior to operation, and to help to find the complication like degenerative changes by measuring the range of motion on the adjacent segment after the spinal fusion. Authors analyzed the result of 29 cases of posterolateral lumbar spinal fusion which were operated from February 1989 and January 1994. The intervertebral angle was measured on the flexion and extension lateral radiographs, and the calculated angular motion and sagittal plane rotation at follow-up periods were compared with those of preoperative values. The results were as follows; 1. Among the adjacent segm0ent, the increment of angular motion of superior adjacent segment was 2.6°(-5°~15°) which was higher than that of inferior one with 1.5°(-3°~7°) 2. The increment of angular motion of superior adjacent segment for 1 segment rather than 2 or 3 segments was more than two times with 3.9°(-2°~15°) 3. Regardless of level and range of fusion, the increment of angular motion was 3.0°(-2°~8°) on 4.5th lumbar segment which was increased mostly and 1.5°(-3°~7°) on 5th lumbar and 1st sacral segment which was increased leastly. 4. There were 3 cases showed instability at the superior adjacent segment and no cases showed instability at the inferior adjacent segment among all the cases showing stability prior to operations. In conclusion, the sagittal plane rotation was increased in adjacent segment after posterolateral spine fusion. So, we would recommend that the adjacent segment is very important to the decision of fusion extent and level.

BACKGROUND: For the diagnosis of varicella-zoster virus (VZV) infection, virus culture has been considered the reference method, but it gives delayed results and needs cell culture facilities. Shell vial culture is more rapid, but it also takes 2 days or more and needs cell culture. Immunofluorescent (IF) method has known to be rapid and sensitive. We compared the tube culture, shell vial culture, and direct IF method to find the most efficient diagnostic method. In addition, the MRC-5 cells were compared with A549 cells for the recovery of VZV in culture. METHODS: A total of 48 specimens were obtained from skin vesicles of patients with clinical herpes zoster. The vesicle smears were stained with FITC-conjugated monoclonal antibody. The vesicle aspirates obtained in 2 mL of viral transport media were inoculated into shell vials and tubes containing MRC-5 and A549 cell monolayers. After 48 h of incubation at 36degrees C the shell vials were stained with VZV-specific monoclonal antibody. The tubes were stained with the same antibody after 3 weeks or when the monolayer showed cytopathic effect. RESULTS: The positive rates of direct IF, shell vial culture, and tube culture were 67.5%, 87.5%, and 72.5% respectively. The positive rate of direct IF was increased to 96.4% when inadequate specimens for the direct IF were excluded. The MRC-5 and A549 cells showed no significant difference in the isolation rates of VZV in both shell vial and tube culture. CONCLUSIONS: Direct IF is the most rapid and practical method for the laboratory confirmation of VZV infection when the swab specimen is adequately obtained. The MRC-5 cells are recommended for the tube culture and A549 cells for the shell vial culture.
