Blunt traumatic cardiac rupture is rare and associated with high mortality. The most popular theory of cardiac rupture after blunt thoracic trauma is rapid deceleration with disruption of the atria from their connections to the vena cava and pulmonary veins. In cases with both massive hemothorax and hemopericardium, injury can usually originate from the heart and/or major vessels. Surgical appr...

Hemothorax is defined as a bleeding into pleural cavity. Hemothorax is a frequent manifestation of blunt chest trauma. Some authors suggested a hematocrit value more than 50% for differentiation of a hemothorax from a sanguineous pleural effusion. Hemothorax is also often associated with penetrating chest injury or chest wall blunt chest wall trauma with skeletal injury. Much less common, it ma...

INTRODUCTION Incubation of a blunt-end ligation reaction in the presence of an excess amount of an appropriate restriction enzyme can dramatically increase the yield of recombinant plasmids. The role of the restriction enzyme is to cleave circular and linear concatemers at restriction sites that are re-formed when linear, blunt-ended plasmid molecules ligate to themselves. In almost all cases, ...

Blunt thoracic trauma can result in significant morbidity in injured patients. Both chest wall and the intrathoracic visceral injuries can lead to life-threatening complications if not anticipated and treated. Pain control, aggressive pulmonary toilet, and mechanical ventilation when necessary are the mainstays of supportive treatment. The elderly with blunt chest trauma are especially at risk ...

H l i u a solated blunt abdominal trauma (BAT) represents about 5% of annual trauma mortality from blunt trauma. As part f multiple-site injury (polytrauma), BAT contributes anther 15% of trauma mortality.1 Exsanguination accounts for 0 to 90% of acute deaths from abdominal injury. More than 5% of such cases are amenable to surgery, and recent years ave seen safe extension of nonoperative, imag...

Blunt traumatic diaphragmatic rupture is an uncommon but severe problem that is usually seen in polytraumatized patients including blunt abdomino-thoracic trauma due to road traffic accidents, fall from height and penetrating injuries. Regardless of the mechanism, diagnosis is often missed and high index of suspicion is vital. Late presentations are associated with increased morbidity. We repor...

Abstract—Hypersonic flows around spatial vehicles during their reentry phase in planetary atmospheres are characterized by intense aerothermodynamics phenomena. The aim of this work is to analyze high temperature flows around an axisymmetric blunt body taking into account chemical and vibrational non-equilibrium for air mixture species and the no slip condition at the wall. For this purpose, th...

OBJECTIVES Blunt SBI is infrequent and its diagnosis may be difficult, especially in the face of confounding variables. The purpose of this study was to evaluate methods for making the diagnosis of blunt SBI. METHODS Patients with blunt small bowel injury (SBI) were identified from the registries of 95 trauma centers for a 2-year period (1998-1999). Patients with SBI (cases) were matched by a...

BACKGROUND AND OBJECTIVES Blunt trauma to the gallbladder is a rare entity, particularly when no other organ is injured. In isolated blunt traumatic injury to the gallbladder, treatment options vary depending on the specific injury. The types of blunt trauma injuries to the gallbladder and their appropriate management are discussed. In addition, a case successfully managed with minimally invasi...

INTRODUCTION Heart valve injury following blunt chest trauma of car accidents is increasing. Although aortic valve involvement is rare, however, in survivors of blunt cardiac trauma it is the most commonly involved valve and the most frequent valve lesion is isolated injury of the noncoronary cusp of aortic valve. CASE PRESENTATION A 31-year-old man with a history of car accident (five months...
