Spontaneous rupture of the pulmonary alveoli after a sudden increase intra-alveolar pressure is a common cause of pneumomediastinum, which is usually seen in healthy young men. Other common causes are traumatic and iatrogenic rupture of the airway and esophagus; however, pneumomediastinum following cervicofacial emphysema is much rarer and is occasionally found after dental surgical procedures, head and neck surgery, or accidental trauma. We present two cases of pneumomediastinum following cervicofacial subcutaneous emphysema after oral trauma. They constitute an uncommon clinical entity, So its radiologic appearance, clinical presentation, and diagnosis are described.

Aortic dissection is a challenging disease and the causes of that are well-known. Blunt chest trauma is one of the causes of aortic dissection. In such cases, nearly all cases involves the isthmic portion of descending aorta, but ascending aorta is involved in about 10. We experienced a patient who had ascending aortic dissection due to automobile accident and who showed spontaneous rupture of the aorta during operation. In this case, after installation of aortic line via left femoral artery, ascending aorta ruptured and a large amount of blood gushed out, which was suckered by cardiotomy sucker. A little delay of cardiopulmonary bypass may cause the fatal outcome in such a case because the bleeding from aorta is too much to be controlled. Fortunately, we controlled the bleeding with cardiopulmonary bypass and got the good outcome of this patient by interpositioning the vascular graft. One should suspect the possibility of aortic dissection in blunt chest trauma, and prepare all the facilities against bleeding due to rupture.

Surgical correction of patent ductus arteriosus is,under most circumstances,highly successful and carries a low mortality. But infected PDA is yet potentially dangerous due to its frequent recurrence and resistant organisms to antibiotics. And,in surgical correction,surgeon may face the possibility of tearing of ductus arteriosus arterial end due to friability and adhesion of its surrounding tissue.This report demonstrats another problem in treatment of infected patent ductus arteriosus.This thirteen years old female patient received susceptible combined antibiotics intravenously from the day of admission and remitted from 4th.week of therapy.This remission state continued for 12days without relapse.But the pulmonary artery ruptured in this remission period.In autopsy,bacteria was not found in ductal vegetation.Also,there was no pulmonary artery aneurysm,Our experience show that in infected PDA,pulmonary artery can rupture spontaneously during remission period without aneurysmal formation.

Occasionally, extensor hallucis longus tendon (EHL) ruptures becames open by laceration and spontaneous rupture of EHL that has previous story of diabetes mellitus, steroid injection, systemic steroid administration, operation and rheumatoid arthritis. But, closed traumatic EHL ruptures are reported rarely. Especially, we diagnosed the closed EHL ruptures in TaeKwonDo players. We reported the 2 patients, differently treated end to end anastomosis and EHL transfer, had the course and treatment methods. Be care the prognosis can be altered according to the treatment time and method.

저자들은 전에 증상이 없던 환자에서 돌발적인 흉통과 호흡곤란이 발생하고, 단순흉부사진상 종격동 종괴와 좌흉막유출을 보여 종격동 기형종의 흉막강내 파열의 기능성을 고려했다. 진단이 쉽지 않은 급성증상에 대해 다른 흔한 흉곽내 질환들과의 감별진단이 필요했으며, 흉막강천자상 편평상피세포와 모발을, 흉부 단층촬영사진상 지방밀도를 포함한 다양한 밀도를 가진 종격동 낭성종괴를, 초음파유도 경피적 세침흡인술상 무핵의 편평상피를 포함한 무균성의 양성 낭성병변을 확인했다. 이러한 임상적, 세포학적, 방사선학적 검사소견으로 수술 전에 종격동 기형종의 흉막강내 파열을 진단할 수 있었으며, 본 증례에서는 측정되지 못했지만, 낭종액와 흉막유출액의 amylase 측정은 이러한 진단을 지지할 수 있을 것으로 생각된다.

A bronchial artery aneurysm (BAA) is uncommon and usually associated with chronic inflammatory lung disease or a systemic vascular condition, which is rarely the etiology of mediastinal hemorrhage. A middle-aged person presented with spontaneous hemothorax and hemomediastinum. A diagnostic evaluation identified a bronchial artery aneurysm as the source. To prevent further rupture, we performed a bronchial artery embolization. In the absence of trauma or other causes for hemothorax and mediastinal hemorrhage, the possibility of a BAA should be considered. A bronchial artery aneurysm can be managed by interventional techniques as well as surgery.

Numerical simulations are conducted to investigate the mechanism of spontaneous ignition of hydrogen within a certain length of downstream pipe released by the failure of pressure boundaries of various geometric assumption. The results show that local ignition is developed in limited area such as boundary layer and the mixing of hydrogen and air is weak at the planar pressure boundary conditions, whereas the flame fronts at the contact region are developed at the pressure boundaries of the spherical shape.

Herpes zoster is a viral infection caused by the reactivation of the varicella zoster virus, an infection most commonly affecting the thoracolumbar trunk. Herpes Zoster Infection (HZI) may affect the cranial nerves, most frequently the trigeminal. HZI of the trigeminal nerve distribution network manifests as multiple, painful vesicular eruptions of the skin and mucosa which are innervated by the infected nerves. Oral vesicles usually appear after the skin manifestations. The vesicles rupture and coalesce, leaving mucosal erosions without subsequent scarring in most cases. The worst complication of HZI is post-herpetic neuralgia; other complications include facial scarring, motor nerve palsy and optic neuropathy. Osteonecrosis with spontaneous exfoliation of the teeth is an uncommon complication associated with HZI of the trigeminal nerve. We report several cases of osteomyelitis appearing on the mandible, caused by HZI, and triggering osteonecrosis or spontaneous tooth exfoliation.

All 10 cases of spontaneous rupture of esophagus had violent vomiting as precursor. 9 patients were male, 1 case was female. Chief complaints were chest pain and dyspnea. Chest P \ulcornerA and esophagogram were mainly used as confirm diagnostic tool. Perforation sites of all cases were at distal esophagus near the G-E junction. 6 cases were received primary repair within 24 hrs, other cases were managed with surgical drainage after exclusion and diversion of esophagus. Empyema was the most frequent complication. Other complications were sepsis, pneumonia, leaking etc. Overall mortality rate was about 70.0%.
