Penetrating gallbladder injuries are uncommon in the pediatric population. The treatment varies according to the severity of the injury and the patient's hemodynamics. We present the case of an 11-year-old male with an accidental pellet gunshot wound to the right upper abdomen that resulted in a grade III liver laceration and damage to the anterior gallbladder wall. The patient underwent laparoscopic cholecystectomy with drain placement. Postoperative radiography of the surgical specimen confirmed the presence of the pellet in the gallbladder. The patient recovered uneventfully and was discharged home on postoperative day 3. Laparoscopic cholecystectomy is a feasible treatment option for penetrating gallbladder injuries in hemodynamically stable patients.

A clinical analysis of 82 cases who were sustained the penetrating gun-shot wound in the chest by 8 bullets was done during 4~ year-period from January 1978 to August 1982 in the department of thoracic surgery, CA FGH. Among 82 cases, 61 cases [74.4%] of them were brought to the Hospital by ambulance, 21 cases [25.6%] were by Helicopter and 76 cases [92.7%] of them were admitted within 4 hours after wounding. Thirty eight [46.3%] patients were treated by closed thoracotomy only, 19 cases [23.2%]by open thoracotomy, 18 cases [22.0%] by primary closure with debridement, and 7 cases [8.5%] by vascular surgery. Causes of open thoracotomy were due to massive intrapleural bleeding in 16 cases, rupture of diaphragm in 2 Gases, and heart injury in one case. Among 25 cases of surgical complications, wound infection was most common in 16 cases [53.5%] and recurrent pneumothorax in 3 cases [10%], empyema in 3 cases [10%], and BPF in one case [3.3%]. Hospital mortality was seen in 6 cases due to hypovolemic shock and respiratory insufficiency in 4 cases, spinal shock in 2 cases due to spinal injury.

The following research was initiated in order to compare the relationship between the amount of gunfire shot and its resulting heavy metal pollution rate. The research was conducted at two firing ranges located inside a military unit stationed in the rear strategical area, where one full distance firing range is used by soldiers in active service, and the other is used by recruits and reserves. The heavy metal pollution rate was measured also on water sample collected from the target zone while raining. Based on values such as the real amount of gunshot fired, amount of heavy metal in the soil of the target zone, and the degree of heavy metal pollution for each firing range, the research showed that although pollution rate was higher when more gunshots were fired, there was no close correlation between the two. The water samples showed that this might result from the soils containing heavy metals eroded and transported by rain due to the target zone having no vegetation.

The usual cause of penetrating thoracoabdominal injuries with evisceration are stab wounds with knives and other sharp weapons used during fights and conflicts. Evisceration of the abdominal viscera as a result of trauma, with its attendant morbidity and mortality, requires early intervention. Gunshot wounds can also cause penetrating thoracoabdominal injuries. We report the case of a 52-year-old male patient, a worker at a timber-processing factory, who was assaulted with a chainsaw by his colleague following a disagreement. He was seen at the accident and emergency department of Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria with a thoracoabdominal injury about 1.5 hours after the attack. He had a left thoracoabdominal laceration with abdominal evisceration and an open left pneumothorax. He was managed operatively, made a full recovery, and was discharged 16 days after admission. He was readmitted 4 months after the initial surgery with acute intestinal obstruction secondary to adhesions. He underwent exploratory laparotomy and adhesiolysis. He made an uneventful recovery and was discharged on the 9th postoperative day for subsequent follow-up.

This paper presents the analysis of tactile effects on different body parts according to the various vibration patterns. The experiments use a vibration pad made of 16 vibration elements in the form of $4{\times}4$ array. The vibration elements are controlled by a 8-bit microprocessor. The sound of gunshot initiates a vibration pattern on different body parts and its sensitivity is measured. The analysis of the experiments lead us to conclude that the vibration pad is the most realistic interface for shooting games and the shoulder part is the most sensitive part in the body. In addition, the most effective vibration pattern is the for the pattern which gives the sensation of spreading out from the center to the outside. This study analyzes the relationship between the human body parts and the tactile sensations by the various vibration patterns. The result of this study will be a good reference for user studies in the field of haptics based on the vibration.

Trauma to the thorax represents a significant portion of injuries seen in an inner-city emergency room. Although most of these patients may be sucessfully managed without thoracotomy, a certain percentage requires operative intervention either immediately or within several hours. 126 records of patients who had early thoracotomy for chest trauma from March 1986, to June 1997, in the Department of Thoracic and Cardiovascular Surgery in Masan Samsung General Hospital were reviewed. There were 96 males and 30 females whose ages ranged from 4 to 72 years, with a mean age of 32.8 years. The modes of injury were as follows : stab wounds, 55 cases(44%), blunt trauma, 70 cases(55%), and gunshot wound, 1 case(1%). Immediate operation was performed in 105 cases(84%) and delayed operation in 21 cases(16%). Indications that operation was necessary were hemorraging and shock in 66 cases(52%), cardiac tamponade in 27 cases(21%), and rupture of the diaphragm in 33 cases(27%). Most of these patients were sucessfully treated but 21 cases were resulted in death. The mortality rate was 16.6% and common causes of death were irreversible shock and hypoxia.

A chinical analysis was performed on 383 ases of hest injurjes eperienced at Department of thoraci Surgery, Seoul National University Hospital during 21 year period From 1957 to 1977. Of 383 patients o hest injuries, 209 cases were result from nonpenetrating injuries whereas 175 were from penetrating injuries, and there were 258 cases of hemothorax or/and pneumothorax, 162 of rib fracture, 33 of foreign body, 26 of clavicle frcture, 26 of lung contusion, 17 of diaphragmati laceration, 14 of hemoperiardium, 14 of flail chest and others. Stab wound was the most common in penetrating injuries and followed by gunshot and shell fragments. The majority of nonpenetrating chest injury paiens were traffi accident vitims and falls accounted for the next largest group of accidents. Chest injuries were frequently encountered in the age group between 16 and 50 years, and 321 patients were male comparing to 62 of female. In blunt hest injuries the patients with five or more rib fractures had a 85 per ent incidence of intrathoracic injury and 19 per cent had an intraabdominal organ damage, whereas those with four or less rib fractures had a 69 per cent and a 6 per cent incidence respectively. The principal associated injuries were cerebral contusion on 19 cases, renal contusion on 10, liver laceration on 7, peripheral vessel laceration on 5, spleen laceration on 3 and extremity fracture on 18 patients. The principles of therapy for early complications of chest trauma were rapid reexpansion of the lungs by thoracentesis (46 cases) and closed thoracotomy (125 cases) but open thoracotomy had to be done on 90 cases (23.5%) because of massive bleeding or intrapleural hematoma, foreign body, cardiac injury, diaphragmatic laceration and bronhial rupture. The over all mortality was 2.87 per cent (11 among 383 cases), 8 cases were from penetrating injuries and 3 from nonpenetrating injuries.

The fibula free flap has now become the most reliable and frequently used option for mandible reconstruction. Recently, three dimensional images and printing technologies are applied to mandibular reconstruction. We introduce our recent experience of mandibular reconstruction using three dimensionally planned fibula free flap in a patient with gunshot injury. The defect was virtually reconstructed with three-dimensional image. Because bone fragments are dislocated from original position, relocation was necessary. Fragments are virtually relocated to original position using mirror image of unaffected right side of the mandible. A medical rapid prototyping (MRP) model and cutting guide was made with 3D printer. Titanium reconstruction plate was adapted to the MRP model manually. 7 cm-sized fibula bone flap was designed on left lower leg. After dissection, proximal and distal margin of fibula flap was osteotomized by using three dimensional cutting guide. Segmentation was also done as planned. The fibula bone flap was attached to the inner side of the prebent reconstruction plate and fixed with screws. Postoperative evaluation was done by comparison between preoperative planning and surgical outcome. Although dislocated condyle is still not in ideal position, we can see that reconstruction was done as planned.
