The bronchogenic cyst, one of rare congenital cystic disease, was reported occasionally since the first description of Bartholinus in 1678. The increased use of roentgenograms of the thorax and the widening scope of thoracic surgery was made, and much more cases of bronchogenic cysts has been observed. The most common location of a mediastinal bronchogenic cyst was the hilum. The treatment for bronchogenic cyst is surgical resection. Forty eight cases of bronchogenic cysts which were pathologically confirmed, are reported and the related literatures are reviewed.

A tracheo-esophageal fistula following from blunt chest trauma is one of less common lesion and few guidelines are available to direct its optimal management. Herein, we report a 24-year-old man injured in a motor vehicular accident sustained a nonpenetrating double blowout injury of the thorax and large tracheoesophageal fistula occurred. Tracheal defect required resection and reconstruction, of which the membranous portion underwent closure with borrowed adjacent esophageal wall primarily and substernal left colon interposition was performed 4 weeks later.

In the diagnostic evaluation of thoracic lesions, the image-guided transthoracic needle biopsy was developed, and its role was expanded with the development of cross-sectional detection and characterization of thoracic lesions and advances in biopsy needle design and techniques. Particularly for diagnostic evaluation of solitary pulmonary nodules, transthoracic needle biopsy has emerged as the invasive procedure of choice. This article covers the indication, the pre-procedure preparation, various guidance-modalities and techniques, and complications.

Recently we experienced one, case of epiphrenic esophageal diverticulum of a 50 - year - old female patient who had complained heaviness in her chest after meals and occasional dysphagia for one year. Preoperative barium study showed a large epiphrenic esophageal diverticulum at about 7cm above the diaphragm which protruded to the right side of the mid thorax. On the operation field, epiphrenic esophageal diverticulum, measuring 5x 6x3cm in size, was noted. Diverticulectomy and extended myotomy was performed and the postoperative course was uneventful.

Thoracic outlet syndrome refers to compression of the subclavian vessels and brachial plexus at the superior aperture of the thorax. A 35-year old female was evaluated for right hand numbness. This patient had a history of headache, right shoulder pain, and right hand numbness during 10 months.Preoperative angiography, EMG, and NCV was performed. First rib and cervical rib resection was done with transaxillary approach. After operation, right hand numbness and right shoulder pain were disappeared. Postoperative course was uneventful.

Traumatic rupture of the right hemidiaphragm occurred following a high-velocity motor vehicle collision in the case presented herein. The resulting herniation of small bowel loops into the thorax resulted in hemodynamic and respiratory compromise due to pressure effects on the right heart and major vessels. The patient's hemodynamic status improved with reduction of enterothorax, and the diaphragmatic defect was repaired. We discuss the available literature and learning points from this rare case.

When the golf club hits the ground prior to making contact with the golf ball, we define it as 'fat shot'. The aim of this research was to investigate the difference between normal shot and fat shot in golf. Five candidates playing as recreational golfer participated in this research and they were all right-handed people. Time phase between each event, wrist cocking angle, elbow extension-flexion angle, backswing height, pelvis angle, thorax angle, L-GRF, R-GRF, pelvis linear velocity, pelvis angular velocity and COG path were calculated. For statistical analysis the paired T-test was used. An early un-cocking, an early right elbow extension and impact with leaving their weight behind foot were not reasons of fat shot. Backswing height, X-Factor, pelvis angle and thorax rotation angle were not different between normal shot and fat shot. But we could find a pattern of abrupt pelvic movement and weight shift to target direction just before impact in case of fat shot. In addition fat shot showed time-delayed and small value of pelvis linear velocity pattern to upward during downswing phase as against normal shot.

A Study on the distribution and types of the total 40 CT units, as of 1st October 1990, in Pusan area(29 for whole body CT units, 11 for brain CT units) were carried out during the period from January 1989 to December 1989 to find out the status of operation and utilization of whole body CT units. The results were as following ; 1. As of 1st October 1990 in Pusan area, a total of 40 CT units(29 for whole body CT units, 11 for brain CT units) were set up and operated. The number of cases of CT examination performed per day per unit were appeared to be less than 5 cases among 59.5% of CT units, and 2.7% of the total units has peformed more than 16 examinations. 2. The CT units under operation occupied 93.5% of the total and 2.6% of the total units was not properly been operated due to mechanical breakdown. This results is appeared to be better than other reports. 3. The average number of scanning per week for each CT were 35 cases and the average days under operation of the unit per week were 6.7 days. Consequently, the average days under operation of units was higher than that of the other reports, but the average number of scanning was lower. 4. The cases referred from other institutes to hospitals were 6.4% of total cases. 5. As a site of scanning, the brain appeared most frequently with 71.2% of the total cases and followed by spine 12.4%, abdomen 8.5%, and thorax 3.6%, respectively. 6. Positive rate by scanning was 70.8% of total cases, and it was 98.9% with thorax, abdomen 96.3%, spine 93.1%, and brain 38.4%, respectively. According to the results of this study, it is highly recommended that the regulations and the guidelines for setting-up of such high cost medical equipments as CT units be provided in order to ensure the cost-effectiveness of the system.

The purpose of this study was to analyze the joint torque of triple segmental system in golf driver swing. For this purpose, joint torque were calculated. In order to determine the load on the lumbar region, a triple segmental system was set for wrist, left shoulder and lumbar, torque working on the lumbar region were estimated. For this study, a total of 7 professional golfers were sampled, and then, their driver swings were recorded with two high-speed digital video cameras (180 frames/sec.) to be synthesized into 3-dimensional images and coordinated. Then, Eular's equation was used to produce some kinematic data, which were used to calculate joint torque with Newton's function. All data were calculated using LabVIEW 6.1 graphic program. The results of this study can be summarized as follows; It was found that the joint torque was generated in the direction opposite the target on wrist and shoulder during down swing, while in the direction towards the target on the lumbar region. During impact and release, the torque on the wrist joint was converted from the direction opposite the target to the direction towards the target, while the torque on the lumbar region was generated vice versa. The joints on the club-arm-shoulder were generated in the opposite direction at the beginning of down swing when the torque on the thorax-pelvis began to be generated, and then, the torque on the thorax-pelvis began to lower, while that on the club-arm-shoulder began to increase. Thus, a rapid decrease of the torque on the lumbar region linked to the low trunk acted to increase moment and joint torque on the arm-club region.
