Review Case ReportsIntussusception in an adult secondary to an inverted Meckel's diverticulum.
Intussusception secondary to an inverted Meckel's diverticulum is considered to be a rare occurrence. The pathophysiology of the disease process results in a complicated clinical picture of chronic abdominal pain, lower gastrointestinal bleeding, and recurrent obstructive symptoms that may lead to an unnecessary delay in diagnosis. ⋯ The methods of diagnosis and the salient concepts in the surgical management of intussusception are discussed. Special features regarding the pathophysiology and treatment of an inverted Meckel's diverticulum acting as an intussusception are also reviewed.

Pulmonary contusion is the most common injury identified in blunt chest trauma. Despite improvements in diagnostic imaging and critical care, the associated mortality has not appreciably changed over the last three decades. Parenchymal injury ultimately manifests as alveolar collapse and lung consolidation. ⋯ Avoiding fluid overload, oxygen therapy, and a low threshold for mechanical ventilation are useful therapeutic guidelines. Complications include pneumonia and adult respiratory distress syndrome, which may occur in up to one half of all cases. Pulmonary contusion is a serious injury that may complicate patient management as well as pose a vital threat.
