A clinical evaluation was performed on 56 patients[ 60 cases ] of open thoracotomy in spontaneous pneumothorax who were admitted and treated at department of Thoracic and Cardiovascular Surgery, Chung Ang University, Yong San Hospital during the past 3 years from March 1990 to February 1993. The results were as follows. 1. The sex ratio was male predominence [ M:F = 7:1 ]. 2. The most common age group were 2nd, 3rd decades. 3. The most common chief complaints were dyspnea and chest pain [46.3% ]. 4. The etiologic factors of spontaneous pneumothorax were primary spontaneous pneumothorax [ 78.3%], secondary tuberculosis [ 18.3%], and others [ 3.4% ]. 5. The site of spontaneous pneumothorax was 50% in right, 40% in left, and 10% in both. 6. The state of activity on attack was almost in the usual life [ 98.3% ]. 7. Average height was 172.5 $\pm$ 5.39 cm in male and 164.0 $\pm$ 3.51 cm in female, average weight was 59.1 $\pm$ 7.06 kg in male and 52.0 $\pm$ 4.97 kg in female. 8. The common indications of open thoracotomy were recurrence [ 34.4% ] and persistent air leakage [ 17.8% ]. 9. The operative procedures were bullectomy [ 73.3% ], partial resection [ 11.7% ], lobectomy [ 11.7% ], and others [ 3.3% ]. 10. The most frequent location of bulla or bleb were apical segment of RUL [ 43.3 % ] and apicoposterior segment of LUL [ 40.0% ]. 11. The number of visible bulla or bleb were mainly 1 to 5, and size was about 1 to 3 cm.

We have reviewed 330 cases of spontaneous pneumothorax from Jan. 1980 to Jul. 1987 at the department of Thoracic and Cardiovascular Surgery, College of Medicine, Korea University. The ratio of male to female was 8.4:1, predominant in male. The incidence according to the age group was highest as 32% in the adolescence between 21 and 30 years old. The site of pneumothorax was right in 48%, left in 45% and bilateral in 7%. The initial symptoms were frequently dyspnea in 85%, chest pain in 63%. The etiologic factors were as follows; bleb origin in 31%, tuberculous origin in 30%, COPD in 3.3%, lung cancer in 1.5%, unknown in 29%. There was no significant difference in seasonal incidence irrespective of tuberculous or sex. The employed managements were as follows; bed rest with oxygen inhalation in 4 cases, closed thoracostomy in 326 cases, open thoracotomy in 122 cases, median sternotomy in 23 cases. The operative procedures at thoracotomy were as follows; simple pleurodesis in 5 cases, bleb excision or wedge resection in 113 cases, segmentectomy or lobectomy in 17 cases, decortication in 42 cases. Recurrence rate of each treatment was as follow; 50% in conservative treatment, 19% in closed thoracostomy, 2% in open thoracotomy, 4% in median sternotomy. Therefore overall recurrence rate was 12%. Open thoracotomy was the most effective procedure in recurrent pneumothorax, previous contralateral pneumothorax, bilateral simultaneous pneumothorax, visible bleb or bullae on the chest x-ray and persistent air leakage. 23 cases of unilateral spontaneous pneumothorax was examined whether or not underlying pathology of pneumothorax at opposite lung. 18 cases[78%] were positive findings. Therefore, bilateral thoracotomy by median sternotomy was a good operative method preventing contralateral pneumothorax.

Introduction: Microsurgical replantation of amputated digit have become common procedure in recent years. However replantation of fingertip amputation, Zone I by Yamano classification, is still difficult because digital arteries branch into small arteries and also digital veins are hard to separate from the immobile soft tissue. So, fingertip amputation was covered by volar V-Y flap, composite graft, cross finger flap and groin flap. But patients who have been treated by these methods experience shortening of digit, nail deformity, excessive tenderness and persistent pain. Replantation could solve most of these problems. Material & Methods: In our department, from March 2004 to August 2007, 36 digits in 32 patients with complete amputation at distal to nail base were replanted using a microsurgical technique. Results: The overall survival rate of the replanted finger was 75%. Venous anastomosis was possible in 8 cases and impossible in 28 cases. In latter cases external bleeding technique was applied with medical leech. Conclusion: After replantation, a few patient complained decreased sensibility, nail deformity and cold intolerance. But most of patients were satisfied with the functional and cosmetic appearance of the viable replanted digits. We believe the replantation should be the first choice in fingertip amputation.

Primary hyperparathyroidism is still uncommomn disease in Korea. However the frequency of this disease has been slowly increased with routine measurement of serum calcium and increasing awareness of hyperparathyroidism in recent years. The diagnosis is established by a persistent elevation of serum calcium and parathyroid hormone and by clinical evaluation. This is a report of eleven patients with primary hyperparathyroidism treated with surgical operation during a period from 1983 to 1997 at Department of Hospital. Authors analyzed the cases to evaluate clinical characteristics and outcome of surgical treatment retrospectively. The result was as follows. 1) In sex distribution, female patients were eight and three were male, the age distribution ranged from 18 to 67 years. 2) The presenting clinical manifestations were renal and urinary stone in eight, bone pain or fracture in six, muscle weakness in four, neurologic symptoms in four, neck mass in three, hypertension in two, and G-I symptoms in one. 3) All patients showed hypercalcemia and elevated serum parathyroid hormone level. 4) Preoperative localization study was performed with computerized tomography, ultrasonography, MRI, arteriography and thyroid scaning. 5) The tumor locations were left lower in eight, left upper in one, right lower in one, and right upper location was one case. 6) Histopathologic findings disclosed adenoma in all cases. 7) All patients were treated by surgical excision and postoperatively transient hypocalcemia occurred in six patients, but no other complication was developed.

Three cases of hyperparathyroidism are presented from our experience at Presbyterian Medical Center in Chonju in the hope that this will alert us all to the variegated patterns of clinical presentation. In the first case the principal symptom was muscular weakness. In the second a bone cyst (which was part of the syndrome of osteitis fibrosa cystica); and in the third case rib cage tenderness, backache, and persistent epigastric pain. All three had adenomas, but in Case 2 the adenomas were multiple. All three responded to surgical resection and remain well.

Background: Left ventricular rupture after acute myocardial infarction is a serious complication with high mortality. Emergency operation is usually the only available treatment. A 76-year-old female with persistent chest pain and syncopal attacks was admitted. Transthoracic echocardiography showed the pericardial effusion and generalized hypokinesia of the inferolateral wall of left ventricle. Coronary angiography revealed a total occlusion of the first diagonal branch. After percutaneous transluminal coronary angioplasty with coronary stent and insertion of intraaortic balloon pump, emergency operation was performed. Under cardiopulmonary bypass and cardiac arrest with cold blood cardioplegia, coronary artery bypass graft with saphenous vein, pericardial patch covering on the rupture area with 6-0 polypropylene running sutures, and fibrin glue compression under the patch were performed. We present a case of left ventricular (free wall) rupture after acute myocardial infarction.

Vinegar is a very popular ingredient used in many cuisines. It is also known for its beneficial health, beauty and possible weight-loss properties. The authors report on a patient who presented to the emergency department with unstable vital signs complaining of generalized abdominal pain after ingestion of 450 ml of apple cider vinegar. We documented a case of corrosive gastrointestinal injury with persistent metabolic acidosis occurring after ingesting apple cider vinegar with an acetic acid concentration of 12~14%. Toxic damage to the liver and kidney were also observed, peaking on post-ingestion day 3. The patient received supportive care and hemoperfusion for three days without much clinical improvement and died in the seventh day of intensive care due to disseminated intravascular coagulation and multi organ failure. Edible vinegar, when taken in large amounts, is capable of inducing corrosive injuries of the GI tract as well as severe systemic toxicities, such as metabolic acidosis. Safety precautions regarding vinegar deserve more public attention and clinicians also should be astute enough to recognize the potential damage accompanying vinegar ingestion.

The purpose of this study is to evaluate histologically the tissue response and resorption of various nonresorbable and resorbable suture materials used for periodontal surgery, using a subcutaneous model on the dorsal surface of the rat. In this study, 10 Sprague-Dawley male rats (mean BW 150gm) were used and the commercially available materials included polyglactin 910, pain gut, nylon, e-PTFE. Animals were sacrificed at 3 days, 1, 2 and 4 weeks after implantation of various nonresorbable and resorbable suture materials. Specimens were prepared with Hematoxylin-Eosin stain for light microscopic evaluation. The results of this study were as follows: 1. Resorption : The resorption of plain gut was showed at 1 week after implantation, was lost their structure and almost resorbed at 4 weeks. The resorption of polyglactin 910 was started at 2 weeks and slowly absorbed untill 4 weeks. 2. Tissue response : Plain gut showed persistent and severe inflammatory reactions from 3 days to 4 weeks. Polyglactin 910, e-PTFE and nylon showed mild inflammatory reactions. Suture material should be biocompatible and be able to be functioned until tissue tensile strength reaches maximum level. In this study, polyglactin 910, nylon and e-PTFE are considered to be proper suture materials for periodontal surgery.

Primary anaplastic large cell lymphoma (ALCL) of the lung is highly aggressive and quite rare. We report here a case of anaplastic lymphoma kinase-positive endobronchial ALCL, that was initially thought to be primary lung cancer. A 68-year-old woman presented with hemoptysis, dyspnea, and upper respiratory symptoms persisting since 1 month. The hemoptysis and and bronchial obstruction lead to respiratory failure, prompting emergency radiotherapy and steroid treatment based on the probable diagnosis of lung cancer, although a biopsy did not confirm malignancy. Following treatment, her symptoms resolved completely. Chest computed tomography scan performed 8 months later showed increased and enlarged intra-abdominal lymph nodes, suggesting lymphoma. At that time, a lymph node biopsy was recommended, but the patient refused and was lost to follow up. Sixteen months later, the patient revisited the emergency department, complaining of persistent abdominal pain since several months. A laparoscopic intra-abdominal lymph node biopsy confirmed a diagnosis of ALCL.
