Neurolytic splanchnic nerve block is effective for treatment of intractable upper abdominal cancer pain. Conventional approach for splanchnic nerve block is conducted in the prone position to ensure proper orientation and to allow insertion of needles on each side of the vertebral body. However, the prone position has some technical disadvantages as this position is frequently poorly tolerated by a majority of patients with advanced cancer due to severe abdominal pain, ascites and so on. Male patient, 53-year old with transverse colon cancer, carcinomatosis peritonei and $L_1,\;L_2$ vertebral body metastasis, was admitted for treatment of severe right upper quadrant and right iliac crest pain. We performed neurolytic splanchnic nerve block with transdiscal technique in the lateral decubitus position under fluoroscopic guidance, and well noted the usefulness and the advantage of this technique. The benefits of this technique are safe, simple and effective because the lateral position is better tolerated by patients and makes bony landmarks more accessible during fluoroscopy.

Purpose: This study examined the effects of e position change upon reported discomfort and bleeding complications during bed rest following a liver biopsy. Methods: The research design for this study was a non-equivalent control group quasi-experimental design. Twenty-nine participants were assigned to the treatment group and twenty seven participants were in the comparison group. Following the biopsy, the treatment group participants had a position change from the supine without compression for two hours followed by compressive right lateral position for two hours. The comparison group maintained continuously the compressive right lateral position with sandbag for four hours. Results: There were statistically significant differences in reported discomfort between the treatment and comparison groups following the intervention. No significant differences were found in bleeding complications between the two groups. Conclusion: The results of the study suggest that the positional change is an effective nursing intervention in reducing discomfort without risk of bleeding following a liver biopsy.

Purpose: This study attempted to test whether there are differences in the level and hemodynamic side effects (blood pressure, heart rate, $O_2$ saturation), and nausea & vomiting of spinal anesthesia using hyperbaric bupivacaine according to position (supine, lateral, and prone positions) in orthopedic surgery patients who received podiatric surgery under spinal anesthesia. Methods: This study was conducted with 53 patients who had received orthopedic surgery under spinal anesthesia at I General Hospital. Data were analyzed using SPSS 20.0 through repeated-measures ANOVA, post-hoc test, Chi-test, and Fisher's exact test. Results: The change of position after spinal anesthesia with hyperbaric bupivacaine caused a change in the level of spinal anesthesia (F=12.768, p<.001). However, no difference of blood pressure, heart rate, $O_2$ saturation and nausea and vomiting caused by the change in anesthesia level was observed, and in prone position, drug was administered for the correction of side effects. Conclusion: As expected, recognizing that there can be a change in the level of spinal anesthesia after the change of position in surgical patients, nurse anesthetists should monitor their conditions carefully and continuously.

In cases with maxillary lateral incisor missing, the problems were usually treated by the choice between space opening for prosthetic lateral incisor replacement and space closure with cuspid sub stitution for the alteral insicors. The decision of the choice could be perplexing in evaluation of the individual case. Therefore, various diagnostic criteria, such as occlusion, dental esthetics, canine position and inclination, tooth size relationship, maxillary lip length, and skeletal relation had to be evaluated. On the basis of this diagnostic information, the treatment planning could be established. A case was shown to illustrate the treatment of patient with congenitally maxillary lateral incisor missing.

Electromyographic studies were performed on the action of the masseter muscles. Among the children aged from 6 to 8 years, ten children with normal occlusion and another ten with space maintainer were selected. The children were divided into 3 groups. They were: 1) A group: Children who removed space maintainer 2) B group: Children who inserted space maintainer 3) C group: Children with normal occlusion. The electromyogram was recorded with 4 channel polygraph. (Grass model VII) Electrodes which were cup-typed gold disks, 9 millimeters in the diameter, were located on the superficial layer of masseter muscles. The electromyogram was recorded in the physiologic rest position, molar occlusion, chewing movement, protraction, left lateral movement, and right lateral movement. The conclusions were as follows. 1. In the physiologic rest position, lateral movement, the electrical potentials of the masseter muscles were not changed clearly in each groups. 2. In molar occlusion, chewing movement, The electrical potentials of the masseter muscles of the B group were almost 10% higher than those of A group, and were almost 60-70% in comparision with C group. 3. In protraction, the electrical potentials of the masseter muscles of the B group were almost 40% higher than those of A group, and were almost equal to C group. 4. The electrical activities of the masseter muscles in the mandibular movements were in the following order: (1) Molar occlusion (2) Chewing movement (3) Protraction (4) Lateral movement.

Purpose : To evaluate the reliability and clinical usefulness of ultrasonography in the temporomandibular joint (TMJ). Materials and Methods : Parasagittal and paracoronal 1.5 T MR images and 7.5 MHz ultrasonographs of 40 TMJs in 20 asymptomatic volunteers were obtained. Disc position using MR imaging was evaluated and the distance between the lateral surface of mandibular condyle and the articular capsule using MR image and ultrasonograph of 27 TMJs with normal disc position was measured and compared. Intraobserver and interobserver measurements reliability was evaluated by using interclass correlation coefficients (ICC) and measurement error. Also, the distance measured on ultrasonographs was compared, according to mouth position and disc postion. Results : The normal disc position was found in 27 of 40 asymptomatic joints. At the intraobserver reliability of measurement, ICC at the closed and open mouth position were 0.89 and 0.91. The measurement error was 0.4% and 0.5%. At the interobserver reliability, ICC at the closed and open mouth position were 0.92 and 0.81. The measurement error was 0.4% and 0.7%. At the TMJ with normal disc position, the distances between the lateral surface of mandibular condyle and the articular capsule measured on MR images and ultrasonographs were $2.0{\pm}0.7mm,\;1.8{\pm}0.5mm$, respectively (p<0.05). On the ultrasonographs, the distances at open mouth position were $1.2{\pm}0.5mm$ (p<0.05). At the TMJ with medially displaced disc, the distances at the closed and open mouth position were $1.3{\pm}0.3\;mm\;and\;0.9{\pm}0.2\;mm$ (p<0.05). Conclusion : The results suggest ultrasonography of TMJ is a reliable imaging technique for assessment of normal disc position.
