BACKGROUND During the last century, the management of blunt force trauma to the spleen has changed from observation and expectant management in the early part of the 1900s to mainly operative intervention, to the current practice of selective operative and nonoperative management. These issues were first addressed by the Eastern Association for the Surgery of Trauma (EAST) in the Practice Manag...

purpose: to report a case of hypotonous maculopathy after blunt trauma and its treatment. patient and findings: a 34-year-old woman presented with decreased visual acuity in her left eye following blunt trauma. right eye examination was unremarkable, but visual acuity of left eye was counting fingers. slit lamp biomicroscopy of the left eye was within normal limits, but on funduscopy, papilloma...

introduction lung herniation following blunt chest trauma is extremely rare and only a few hundred cases of this pathology have been reported in the english language medical literature. this type of lung hernia is divided into intercostal, parasternal, or supraclavicular subtypes based on the exact location of the chest wall defect. traumatic intercostal lung hernia is even more uncommon. delay...

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...
