PURPOSE: This study evaluated the treatment effectiveness and proper radiation dose of helical tomotherapy (HT) in spine oligometastases from gastrointestinal cancers. MATERIALS AND METHODS: From 2006 to 2010, 20 gastrointestinal cancer patients were treated with HT for spine oligometastases (31 spine lesions). The gross tumor volume (GTV) was the tumor evident from magnetic resonance imaging images fused with simulation computed tomography images. Clinical target volume (CTV) encompassed involved vertebral bodies or dorsal elements. We assumed that the planning target volume was equal to the CTV. We assessed local control rate after HT for 31 spine metastases. Pain response was scored by using a numeric pain intensity scale (NPIS, from 0 to 10). RESULTS: Spine metastatic lesions were treated with median dose of 40 Gy (range, 24 to 51 Gy) and median 5 Gy per fraction (range, 2.5 to 8 Gy) to GTV with median 8 fractions (range, 3 to 20 fraction). Median biologically equivalent dose (BED, alpha/beta = 10 Gy) was 52 Gy10 (range, 37.5 to 76.8 Gy10) to GTV. Six month local control rate for spine metastasis was 90.3%. Overall infield failure rate was 15% and outfield failure rate was 75%. Most patients showed pain relief after HT (93.8%). Median local recurrence free survival was 3 months. BED over 57 Gy10 and oligometastases were identified as prognostic factors associated with improved local progression free survival (p = 0.012, p = 0.041). CONCLUSION: HT was capable of delivering higher BED to metastatic lesions in close proximity of the spinal cord. Spine metastases from gastrointestinal tumors were sensitive to high dose radiation, and BED (alpha/beta = 10 Gy) higher than 57 Gy10 could improve local control.

The purpose of the present study was to seek bracket-adhesive combinations which have adequate bond strength with no enamel and bracket fracture. The shear bond strengths were measured, the sites of failure and the enamel damage were investigated and the peripheral sealing and adaptation between enamel surface, bonding adhesive and bracket were evaluated 240 noncarious human premolars were divided into twenty four groups of ten teeth. Shear bond strengths of each group were determined in an universal testing machine after two days passed and the debonded specimens were inspected to determine the predominant bond failure sites. To evaluate peripheral sealing and adaption between enamel surface, adhesive and bracket, each specimen was cut longitudinally into two halves which included the midsection of the bracket, adhesive and enamel and exmined in scanning electron microscope. Six different types of brackets were bonded to the tooth with four different type of adhesives. Six different types of brackets were Image, Plastic, Crystaiine, Fascination, Transcend 2000 and metal bracket and four different adhesives were No-mix, Light-Bond, OrthoLC and Superbond C&B. From this study, it may be concluded that (1) The mean shear bond strength varied from a high of 36.58Kg (410.07 Kg/cm2) with the Fascination-Light Bond combination group to a low of 8.93 Kg (75.51 Kg/cm2) with the Image-OrthoLC combination group. When using OrthoLC as adhesive, the mean shear bond strength was significantly lower than that of other combination groups, (2) Regardless of adhesives, the mean shear bond strength of Fascination brackets was relatively high whereas Plastic and Image brackets had low shear bonding strength The shear bond strength of Crystaline bracket and Transcend 2000 was relatively equal to or lower than that-of metal bracket, (3) There was a correlation between bond strength, enamel damage and bracket fracture. As the shear bond strength was increased, the rate of enamel damage and bracket fracture were increased, (4) The combination groups that use OrthoLC as adhesive were debonded in shear stress without enamel fracture and bracket fracture, whereas the combination groups that use Superbond C&B as adhesive experienced a relative high enamel fracture rate and bracket fracture rate, (5) Peripheral sealing and adaptation between enamel-adhesive-bracket were relatively good when using Light-Bond or No-mix as adhesive. Regardless of adhesives, adaptation between bracket-adhesive were relatively good in Ceramic brackets, (6) The combination groups which had adequate bonding strength with no enamel and bracket fracture were Crystaline No mix, Crystaline-Light Bond, Crystaline-OrthoLC, metal-No mix, metal-Light Bond and metal-OrthoLC combination groups.

If the bond strength is sufficient to resist orthodontic force, orthodontic brackets can be bonded to restorations. Orthodontic brackets were bonded to composite resin and glass ionomer cement restorations wtih no-mix adhesive or glass ionomer cement. The shear bond strength of adhesives bonded to restorations was studied in vitro. Orthodontic brackets were bonded to 10 extracted natural teeth, 40 composite resin restorations and 40 glass ionomer restorations. The surfaces of composite resin restorations were roughened or applied with bonding agent (Scothbond) after surface roughening. The surfaces of glass ionomer cement restorations were conditioned with acid etching or applied with Scotchbond to etched surface. The adhesive was no-mix resin or glass ionomer cement. The shear bond strength was measured. The results were as follows: 1. Orthodontic brackets could be bonded to composite resin restorations effectively as they could be bonded to acid etched enamel with no-mix adhesive. The shear bond strength was sufficient to resist orthodontic force and was not affected by bonding agent greatly. 2. The shear bond strength of no-mix adhesive bonded to acid etched glass ionomer cement restorations was sufficient to resist orthodontic force. However, the fracture risk of glass ionomer cement restorations was increased during debonding. The bonding agent couldn't increase the shear bond strength greatly. 3. The shear bond strength of glass ionomer cement bonded to glass ionomer cement restorations was lower than that of no-mix adhesive. The shear bond strength was sufficient to resist orthodontic force and was greatly decreased by bonding agent. 4. The shear bond strength of glass ionomer cement bonded to composite resin restorations was too low to resist orthodontic force.

CT provides a valuable new perspective in assessing abnormalities of the thorax. In patients with amediastinal mass or widening detected by plain chest radiography, a definite diagnosis is sometimes possible whichwould not obtainable by conventional radiological technique. Clinical staging of bronchogenic carcinoma can beachieved by CT better than any other radiologic method. In fifty patients with histologically or angiographically confirmed disease of the thorax,an analysis of chest radiography and chest CT manifestations was made, and theresults were as follows; 1. 27 patients with mediastinal mass detected by chest radiography, a definite diagnosiswas possible in 10 patients (36%), who were 6 with teratodermoid, 1 with thymic cyst, 3 with aneurysm. In allpatients, the extent and localization of mediastinal mass could be established more precisely than by the chestradiography. 2. In 15 patients wtih bronchogenic carcinoma, 9 patients (60%) showed hilar adenopathy ormediastinal adenopathy which could not be noted on the chest radiography. 3. Main CT findings of braonchogeniccarcinoma were peripheral lung mass, spiculated or lobulated margin, adhesion to pleura or chest wall, andatelectasis or chronic pneumonia. 4. Commonly observed CT findings of teratodermoid were well capsulated mass,calcification, fat density , and multi-loculation. 5. Commonly observed CT findings of thymoma were homogenousmass, round contour, partially preserved mediastinal fat. CT was superior in evaluation of mediastinum and in the detemination of the extent of known bronchogenic carcinoma.

62 cases of the fracture of the pelvis admitted to the orthpedic department of Wonju Christian Hospital during past 5 years from 1975 to 1979 were reviewed and clinical results were obtained as follows: 1. Males were frequent than females and almost 3rd to 4th decades of life. 2. The causes of injury were traffic accident, coal minor accident, and falling. 3. Stable type is the most common in this series and among the unstable types, lateral compression type is the most common and then straddle type and vertical shear type. 4. The most common complication is uro-genital injury. 5. The residual complications at the end of treatment remained in some cases, Arthritis of sacroiliac joint, Impotence, Urethral stricture, Low back pain, etc. 6. All of the cases were treated conservatively and their results were somewhat good except 4 cases. 7. Surgical treatment would be considered, if necessory, to decrease the complications and reduce hospital days.

A coronary artery aneurysm was first reported by Bougon in 1812, and was able to be diagnosed during life with advance of selective coronary arteriography. We have recently seen a 62-year-old woman who had intermittent anterior chest pain and dyspnea on exertion(NYHA functional class II) and diagnosed a coronary artery aneurysm by coronary arteriography. A saccular formed coronary artery aneurysm was located at left main coronary artery at the juction of the bifurcation of LAD and left circumflex artery and it's was 2cmx2cm and it's thickness of wall was 0.5cm. After the patency and consistency of coronary arteries were confirmed,resection of aneurysm with aneurysmorrhaphy was performed.

The mortality and morbidity of peritrochanteric fractures in the elderly are great due to preexisting diseases, the osteoporosis, and poor general conditions. Since the complications sometimes lead to death, it is utmost important to reduce the complications and to prevent them. Authors had experienced 42 peritrochanteric fractures over 65 years old from January, 1988 to December, 1992. Age incidence was distributed from 65 to 93 years. The sites of fractures were 17 femoral neck, 24 intertrochanteric, 1 subtrochanteric. The mortality at postoperative 6 months was 10.2%. The postoperative complications were 6 cardiovascular diseases, 3 pneunonia, 3 pressure sore etc. The results according to interval between injury and operation were not significant, but reducing risk factors following check-up of general conditions was significant. It was necessary in treatment of elderly peritrochanteric fractures to check the general conditions, to reduce risk factors, to choose appropriate method of operation and anesthesia, and to operate as soon as possible by experienced surgeon. Postoperative early ambulation was also significant at good results. The percutaneous pinning under local anesthesia was an recommendable method in patients with severely poor general conditions.

Hidroacanthoma simplex (HS) is a rare benign intraepidermal tumor thought to originate from the intraepidermal eccrine duct. Many authors regard it as an intraepidermal form of eccrine poroma but there is still a discussion as to the histogenesis of HS. Clinically, it is more common in older adults and affects both sexes equally. It is found more often on the lower extremities and trunk. The clinical appearance is not characteristic, but the lesions are usually flat or slightly elevated verrucous brown plaques. Histopathologically, the tumor shows characteristic intraepidermal nests and is one of a number of cutaneous lesions showing Borst-Jadasshon phenomenon, that is, tendency to form nests within the epidermis. The tumor cells composing nests show a uniform cuboidal appearance and a round, deeply basophilic nucleus typically. The cytoplasm of tumor cell gives a positive PAS reaction that is diastase-labile. We report herein three cases of HS with the results of immunohistochemical studies.
