Pseudoaneurysm arising from the superficial temporal artery (STA) is a rare and potentially critical cause of palpable mass. Most pseudoaneurysms form as a result of blunt trauma and present as painless, pulsatile mass that may be associated with pathologic finding and enlarged size. We report a rare case of pseudoaneurysm arising from STA caused by blunt injury and diagnosed by 3-dimensional computed tomography (CT) angiography.

Priapism is a pathologic state of persistent penile erection in the absence of sexual stimulation. Low flow priapism is more common, which is caused by a venous outflow obstruction. However, high flow priapism is rare, and is caused by uncontrolled arterial flow into penis following perineal or penile blunt injuries. We report a case of high flow priapism secondary to the treatment of low flow priapism.

Acute abdominal wall rupture with viceral herniation from blunt trauma is uncommon. In general, the shear forces generated by blunt trauma cause injury to the intra-abdominal organs or bony structures more frequently than they do to the abdominal wall itself, probably because of the elastic nature of the abdominal wall. Traumatic hernias have been divided into separate groups on the basis of the type of muscle defect, the size, the injury mechanism, the location, and the severity of injury. We present a rare case in which a herniated abdominal wall rupture following blunt trauma was caused by a hydraulic press brake. We present computed tomography findings and a pertinent review of the literature.

BACKGROUND: Although palmoplantar epidermal cysts have long been associated with develop ment following implantation of an epidermal fragment as a result of a penetrating or blunt injury, the pathogenic mechanism is still not fully understood. Since 1987, many cases have been reported in which human papillomavirus(HPV) could be associated with palmoplantar epidermal cysts. OBJECTIVE: In this study, we evaluated the clinicopathological findings of palmoplantar epidermal cysts and investigated them for the presence of HPV in order to examine the role of HPV in the pathogenesis of this disorder in Korea. METHODS: The clinical, histological, immunohistochemical studies were performed on seven cases of plantar cysts, and two cases of palmar cysts. RESULTS: No previous trauma history was seen. Histopathologically, parakeratotic nuclei, or vacuolar strutures within the keratinous mass in the cyst cavity were found. However, we could not find intracytoplasirnic eosinophilic bodies in the wall, the cyst content, or the overlying epidermis. The dyskeratotic keratinocytes were observed in 3 cases. Papillomavirus common antigens were not detected by immunohissochemical staining. CONCLUSIONS: Palmoplantar epidermal cysts in Korea have some different histological features compared to those of HPV 60-associated cases in Japan and we could not detect the immunohistochemical evidence of HPV infection in our cases.

We reviewed 49 patients(50 eyes) who had undergone pars plana vitrectomy for the traumatized eyes during the last 4 years. We divided patients into 4 groups according to the characteristics of ocular injuries-anterior segment Injury, posterior penetrating injury, intraocular foreign body and blunt injury. We analyzed surgical results and compared surgical outcomes according to timing of vitrectomy performed(within 2 weeks VS more than 2 weeks after trauma). Anatomical success was achieved in 36 eyes(72.0%) and functional success was achieved in 23 eyes(46.0%). The main causes of functional and anatomical failure were macular pucker and phthisis bulbi respectively. The anatomical and functional success rates were higher when vitrectomy was performed within 2 weeks after trauma. In posterior penetrating injury group, however, anatomical success rate was lower when vitrectomy was performed more than 2 weeks after trauma. The frequency of retinal detachment was higher when vitrectomy was performed more than 2 weeks after trauma. In cases of intraocular foreign body, retinal detachments were developed in all patients after vitrectomy performed more than 2 weeks after trauma. If vitrectomy is required for patients with ocular injury, we suggest vitrectomy within 2 weeks after frauma for better chance to perserve the globe and for salvaging vision.

Subclavian artery occlusion after blunt trauma is an extremely rare injury. This has been attributed to its wellprotected location deep in the scalene triangle, bounded by the first rib and clavicle. A case of post-traumatic occlusion of the subclavian artery with clavicle fracture was reported by Sodhi et al in 2006 and in Korea was reported by Han et al in 2001. We believe that is the first report of post-traumatic occlusion of the subclavian artery without clavicle and first rib fracture in Korea.

According to literature data, there are no distinct guidelines regarding the proper diagnostic and therapeutic management of traumatic carotid artery dissection (TCAD). Although most of cases evaluated in research studies refer to spontaneous carotid artery dissection, traumatic cases demand special considerations as far as diagnosis and treatment are concerned. Although both types of dissection share some common characteristics, a patient with TCAD usually presents with several concomitant injuries as well as a higher bleeding risk, thus complicating decision making in such patients. Therefore, aim of this review is to present available data regarding epidemiology, clinical presentation, diagnostics and treatment strategy in cases with TCAD in order to produce useful conclusions for everyday clinical practice.

OBJECTIVE: To study the deduction of injury-causing instruments and its value as judicial evidence. METHODS: To collect 146 cases involved in injury-causing instruments deduction, which accepted by Judicial Appraisal Center of Wannan Medical College during the period from 1998 to 2007, then to deduce the instrument by analyzing the characters of injuries in body surface. The accuracy of those deductions was evaluated by comparing the deduced instruments with the actual instruments. RESULTS: The deduction from sharp injuries was more accurate than that from blunt injuries. CONCLUSION Sometimes the result of deduction about injury-causing instruments are uncertain, it may be accepted as judicial evidence when supported by other evidences.

Three cases who were successfully treated for cardiac injuries by open thoracotomy were reported. The range of the ages of the patients was 3rd decade. Two of the 3 were males with blunt injuries by motor vehicle accident and one was male with stab wound by knife. In the case of blunt injuries, the right atrium was involved in one case and the right and left atrium were involved in the other. The site of stab wound was the right atrium. There were two cases with the pre-operative diagnosis of cardiac injuries and they were blunt injuries. The case of stab wound was not diagnosed pre-operatively. All cases were treated with open thoracotomy-one posterolateral thoracotomy, one median sternotomy and one Clam shell incision. All of them had an uneventfull post-operative course.

We reviewed retrospectively the medical records of 80 consecutive patients with renal injuries, managed at Seoul National University Hospital during a 22 year period from 1965 to 1987. All patients but one who had stab wound presented with a history of blunt injury and the most common cause of injury was fall-down(48%). Renal contusion was most common type of injury(45%) and there were 3 patients(4%) with pedicle injury. All patients presented with hematuria and in 67 patients of 80 the hematuria was gross. Initial diagnostic procedure was excretory urography in 71 patients. Representative cases were illustrated in details. After reviewing and analyzing indications and efficiency of various diagnostic studies in these patients, several conclusions can be made for adequate radiologic plan. In cases of microscopic hematuria without shock, further diagnostic work-up may not be necessary. Computed tomography may be performed initially without excretory urography when multiple or major injuries are suspected. Ultrasonography may be complementary after excretory urography in minor injuries. If findings of excretory urography or ultrasonography were suggestive of major injury or not conclusive, computed tomography is indicated. Angiography may be indicated only when renal pedicle injury is suspected.
