ABSTRACT
Sternal fracture is relatively common after blunt chest trauma, and this usually resolves without complication. But acute extrapericardial tamponade caused by sternal fracture and injury to the internal mammary artery secondary to blunt chest trauma is very rare. We report here on two cases of acute extrapericardial tamponade that were caused by blunt chest trauma.

Salicornia herbacea L. is one of the halophytes that can grow in salt marshes, or salt fields along the seashores in Korea. The objective of this study is to investigate the mechanism by which Salicornia Polysaccharide, (SPS) activates macrophages. To analyze macrophage activation and iNOS gene expression, we performed nitrite generation assay, immunohistochemistry, and reverse transcriptase-polymerase chain reaction. A polysaccharide isolated from the Salicornia herbacea L. significantly induces nitric oxide (NO). Immunohistochemical staining of inducible NO synthase (iNOS) showed that the increase of NO was due to the induction of iNOS production. RT-PCR analysis showed that SPS produced significant induction of iNOS gene expression. Immunohistochemical staining of p65 showed that SPS produced strong induction of NF-kappa B/Rel nuclear translocation. Electrophoretic mobility shift assay further confirmed the activation of NF-kappaB/Rel by SPS. In conclusion, we demonstrate that SPS stimulates the macrophages to express iNOS gene via the activation of NF-kappa B/Rel.

BACKGROUND: Malignant pleural effusion is a common clinical problem in neoplastic patients. With the diagnosis of a malignant pleural effusion, palliative therapy was done. One of the treatments was a chemical pleurodesis. Talc was the most commonly used a sclerosing agent, but the quality of patient's life was not improved. We was evaluated by other agents such as Viscum album for relief of malignant pleural effusion. MATERIAL AND METHOD: From November 2001 to October 2003, 17 patients who underwent to chemical pleurodesis for the malignant pleural effusion. We compared the talc (group I: 10 patients) and Viscum album (group II: 7 patients). We analysed them retrospectively in term of various factors and results. RESULT: There were no significant differences between group I and group II in the sex ratio, mean age, origin of primary cancer and site, but, group I had higher successful rate (80%:71%) than group II. Group II had better length of chest tube stay after procedure, Karnofsky performance and recurrence than group I. The failed treatement group was related to the pleural fluid pH and interval of initial chemical pleurodesis after thoracostomy. CONCLUSION: Although the chemical pleurodesis with Viscum album was slightly lower than talc in the successful rate, there was an alternative method instead of the chemical pleurodesis with talc to improve the patient's quality of life in malignant pleural effusion.

BACKGROUND: Inadequate drainage of traumatic hemothoraces may result in prolonged hospitalization and complication such as empyema, fibrothorax and pleural calcification. This needs to be the placement of a tube thorascostomy which is efficacious in more than 80% of cases. Other cases require surgical treatment. MATERIAL AND METHOD: From March 2002 to February 2003, there were 123 patients who was done closed thorascostomy in traumatic hemothorax. 10 patients (group I) were undergone early retained clot evacuation with video assisted thoracoscopic surgery, but 5 patients (group II) who developed a localized hematoma or empyema were operated. Male were more than female and mean average was similar in both group. The most common cause of injury was traffic accidents and frequently combined lesions were a abdomen. RESULT: Interval from injury and operation, mean operation time, duration of tube drainage and hospital stay in group I were shorter than group II (p<0.05). Operation-related complication and recurrence of fluid collection within follow up period (17.8+/-3.8 months) in group I were none, but in group II (21.5+/-5.3 months) were 2 cases. CONCLUSION: Video assisted thoracoscopic surgery can be utilized as an effective and safe method for the removal of retained clotted hemothorax within 7 days.

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) for decortication or debridement in the management of empyema thoracis has increased the available treatment options but requires validation. We present and evaluate our technique and experience with thoracoscopic management of pleural empyema, irrespective of chronicity. MATERIAL AND METHOD: VATS debridement or decortication was performed with endoscopic shaver system in 40 consecutive patients presented with pleural space infections. A retrospective review was performed and the effect of this technique on perioperative outcome was assessed. RESULT: VATS evacuation of infected pleural fluid and decortication was successfully performed in 35 of 40 patients. The mean duration of preoperative symptoms before referral was 23 +/- 1.8 days. The mean duration of hospitalization before transfer was 13.5 +/- 1.5 days. Blood loss was 250 to 200 mL. Intercostal drainage was required for 5 +/- 3 days. The postoperative hospital stay was 5 +/- 0.7 days. There were no operative mortalities. CONCLUSION: Video-assisted evacuation of infected pleural fluid and decortication is an effective modality in the management of the fibropurulent stage of empyema. An organized empyema should be approached thoracoscopically, but may require open decortication.

We developed an animal model to recreate the condition of an open fracture in communication with the maxillary sinus. We then studied wound healing of the sinus wall structures following fracture in the presence of autogenous bone and alloplastic implant. This model is designed to simulate the repair of an orbital floor fracture in humans. The New Zealand White rabbit was used as the animal model. Standardized 8mm defects were made bilaterally in the maxillary sinuses to include bone and mucosa in 36 rabbits. Two different implants and autogenous calvarial bone graft were placed in the soft-tissue pockets to obturate the defects, exposing one surface of the implant to the open sinus. Medpor porous polyethylene, silicone and calvarial bone implant were compared. Animals were killed at 1, 2 and 8 weeks after implantation. Gross examination of the specimens for the amount of mucosal closure and implant tissue fixation was performed. Histological sections were evaluated for bone and soft-tissue morphology juxtaposed to the implant. Complete closure of the mucosal defect was demonstrated with each type of implant. Medpor implants showed both vascular and soft-tissue ingrowth into pores by week 1. Bone ingrowth was seen by week 2. Closure of the Medpor obturated defects occurred more rapidly than in the silicone group. The Medpor implants and calvarial bone demonstrated bone and soft-tissue fixation, callus formation and maturation, while mature overlying mucosa was reconstituted over the defects. Silicone implants demonstrated a fibrous tissue reaction within 1 week of implantation and they never became fixed to bone or soft tissue. Maxillary sinus wall regeneration occurred in all defects. This study supports clinical observations of maxillary sinus wall regeneration in humans.

A clinical analysis was performed on 326 cases of the non-penetrating rib fractures experienced in the department of thoracic and cardiovascular surgery, Chosun University Hospital and 102 cases of the non-penetrating rib fractures those has been admitted and treated in the department of thoracic and cardiovascular surgery, Jeonnam Hwasoon Jung-ang Hospital during a period from Jan. 1994 to Dec. 1995. 1. Sex ratio was 3.4:1 in urban and 3.6:1 in rural communities with male predominance. 2. Most common cause were traffic accident in both communities. 3. Hemothorax, pneumothorax and hemopneumothorax which needed thoracostomy were observed in 146 cases(44.7%) in the urban and 12 cases(11.7%) in the rural communities. 4. Left thorax was the spell site of rib fractures in both communities. 5. Rib fracture was prevalent from 3rd to 6th rib in both communities. 6. Open thoracotomy was performed in 37 cases(11.3%) in urban and 3 cases(2.9%) in rural communities. 7. Overall mortality was 4.29%(14 cases) in urban area and, 1.96%(2 cases) in rural communities, and cause of death were hypovolemic shock, brain edema, sepsis, respiratory failure, asphyxia, and cardiogenic shock.
