To evaluate the impact of open lung biopsy on diagnosis and treatment of diffuse infiltrative lung disease, we conducted a retrospective review of 28 patients who underwent this procedure at the Kyoungpook National University Hospital from 1986 to 1993. There were 19 men and 9 women; average age was 50.9 years. During open lung biopsy, The region of the lobe was radiographically and grossly identified and was examined by a biopsy. The biopsy yielded a specific diagnosis in 27 [96.4 % patients and changes in therapy in 24[85.7% patients. Complications developed in three[10.8% patients, directly related to the biopsy procedure in 2. One patient died[3.6% due to underlying disease. We conclude that open lung biopsy can be accomplished safely in the patient with diffuse infiltrative lung disease and it is an important tool in decision-making process and therapy.

The purpose of this study is to verify the relations with the fatigue life and stress distribution on the screw thread for thoracic and lumbar spine. These screws are now developed for Korean in this research group. The fatigue life of single screw was found longer than that of up-left-screw, but shorter than that of up-right-screw. The fatigue life of screw used was associated with the angie between bending and thread direction. In the case of upper left and right screw were fractured in the region of one pitch and two pitch of the thread valley from the shank of pedicle screw, respectively.

A 23-year-old male patient complained dyspnea on exertion and orthopnea since December 1977. On examination, he was tall and slender. There was grade IV/VI to-and-fro murmur on the left sternal border especially on Erb`s point. The liver was descended 2 fingers breadth below right costal margin. There were no signs of Marfan`s syndrome. Echocardiography demonstrated partial closure of aortic valve and dilated aortic root with enlargement of ascending aorta. Left heart cardiac catheterization revealed moderately elevated pulmonary wedge pressure and right ventricular pressure. The left ventricular end diastolic pressure was markedly elevated to 26 mmHg. On aortography, the aortic regurgitation was severe and it was belonged to angiographically Grade IV. The aortic valve was replaced with Carpentier-Edwards valve without excision and replacement of ascending aorta, under the impression of rheumatic valvular heart disease. After closure of aortotomy, blood pressure was transiently elevated and bleeding from the site of inserting air vent needle of ascending aorta was developed. The bleeding was not controlled by any means. On postmortem microscopic study, the histologic changes were strikingly limited to the ascending aorta from the region of the aortic valve ring.

Two species of mysid, Nipponomysis fusca (Ii, 1936) and N. tenuiculus (Ii, 1940), are newly recorded in Korean fauna. These two species were collected using a light or a bait trap from all coasts of the Korean peninsula. The genus Nipponomysis can be distinguished from allied genus by the following morphological characteristics: third to eighth thoracic endopods with carpopropodus divided into five to six subsegments compared to three subsegments, and anterior four pairs of pleopod in female subequal in length and fifth pair elongated. Nipponomysis fusca is characterized by its acute rostral plate and armature of telson, and N. tenuiculus differs from other species by the number of spine in ventral statocyst region and the shape of the fourth pleopod in male. Herein, we present detailed descriptions of two species from Korean waters with illustrations of morphology. In addition, an identification key to the Korean species of the genus is provided.

In the treatment of the acute respiratory failure, ventilatory support with endotracheal intubation or tracheostomy is a life saving procedure in many cases but the development of postintubation tracheal stenosis is a very serious complication. Recently we have experienced one case of postintubation tracheal stenosis which occurred in the region of cuff site. Preoperative tracheogram showed a concentric stricture 3.0 cm in length located 4.0 cm proximal to the carina. Under the general anesthesia, the stenotic segment was resected and end-to-end anastomosis was performed successfully through the right posterolateral thoractomy. Her postoperative course was uneventful and the patient has remained well till now.

Laryngotracheoesophageal clefts are rare congenital anmalies of the upper aerodigestive tract. They range in severity from small soft tissue defects in the interarytenoid region to complete clefts of the larynx, trachea, and esophagus. Minor clefts with mild symptoms can be managed conservatively. But, major clefts requires prompt surgical managemet fur the best result. We report a case of a 1 month old male with laryngotracheoesophageal cleft. This cleft was corrected by thoracotomy and anterior laryngofissure approach.

Cardiac myxomas are most common benign tumor and comprise approximately 50% of all primary cardiac neoplasms. They are intracavitary tumors occurring within any of the cardiac chambers, but they have a predilection for the atria and particularly the left atrium. Its are usually arise from the region of the limbus of the fossa ovalis. Clinically, they present with various manifestations due to obstruction to blood flow, embolization, and constitutional changes. Excision with the aid of cardiopulmonary bypass has been established as the treatment of choice for these histologically benign, but potentially malignant tumors and has generally produced good results [17]. We have experienced two cases atrial myxomas, one is left, the other is right and resected under established cardiopulmonary bypass, so we report these cases with the review of the literature.

Chondroblastoma is a rare benign bone tumor most frequently found in the epiphyseal region of long bones. The most common locations are the knee and proximal humerus,but the rib is an unusual site. Second decade is the most common age group. The ossification centers for the rib appear in the second fetal month and ossify in a caudal-to-cranial direction. There are also epiphyseal centers at the head and tubercle of the rib that appear at puberty and ossify in the third decade. The epiphyseal plates of the head and tubercle may be the site of origin of the posterior chondroblastomas; the anterior lesions may arise from the costochondral junction. The histologic features consist of polygonal chodroblast, small foci of chondroid production, osteoclast-like giant cell, and are diagnostic of chondroblastoma.We experienced a case of the chondroblastoma arising from the rib, and its clinical and histologic features are discussed.

Polymelia is an extremely rare congenital anomaly where an individual is born with an abnormally developed extra or supernumerary limb which is generally shrunken and functionless. A case of thoracomelia (a type of polymelia) was observed macroscopically and confirmed radiologically in 1.5 years old boy born in Nepal with an abnormal supernumerary upper limb attached to his back in the thoracic region. The limb was successfully amputated, and the boy had a favorable outcome after surgical treatment, without any adverse effects or impairment. Understanding the embryogenesis of thoracomelia is essential for unraveling the complex mechanisms underlying this condition and potentially aiding in early diagnosis and intervention. This case report and review aims to shed light on the intricate processes governing forelimb formation and their perturbations leading to thoracomelia.

Objectives : The purpose of this study was to investigate effects of long-term taxi driving posture on the balance of musculoskelectal system. Methods : The author practiced Moire topography by using IBS-2000 for 30 male taxi drivers and general people. Then we measured difference of contour lines, difference of shoulder joint height, interval between vertical baseline of pelvis and vertical baseline of neck, ratio of thoracic curve and lumbar curve, difference of width between right and left through Moire topography. After we statistically analyzed difference of Moire topography's data between long-term employed male taxi drivers and general people. Results : 1. Taxi drivers, difference of contour lines in scapular, lumbar, gluteal region was bigger than general people and significant difference(p<0.05) was observed between subject group. 2. Taxi drivers, diference of shoulder joint height was more large than general people and significant difference(p<0.01) was observed between subject group. 3. Taxi drivers, diference of interval between vertical baseline of pelvis and vertical baseline of neck was more large than general people and significant difference((p<0.05) was observed between subject group. 4. Taxi drivers, ratio of thoracic curve was more large than general people and ratio of lumbar curve was more less than general people and significant difference(p<0.05) was observed between subject group. Conclusions : According to above results long-term taxi driving posture might cause musculoskelectal system unbalance.
