A motor vehicle passenger sustained an acute traumatic lumbar hernia caused by an improperly positioned seat belt. Diagnosis was confirmed on computed tomographic scan, and the defect repaired primarily.

Three weeks after a shotgun wound to the chest and abdomen, a patient developed acute ureteral colic caused by a migrating shotgun pellet. The pellet passed spontaneously. A search of the literature revealed 25 similar cases of this unusual complication of missile injuries to the abdomen. ⋯ Cases involving bullets and shrapnel fragments usually have had long latent periods after the initial injury and required surgery to remove the obstructing projectile. In contrast, cases of "buckshot colic" from shotgun pellets present earlier and often resolve with spontaneous passage of the pellet. The following report illustrates how conservative management can be successful in cases of "buckshot colic."

Traditional practice of mechanical ventilation includes tactics to reduce lung injury, such as avoidance of excessive airway pressure, patient distress, and tidal volume. Gas exchange objectives have received priority, however, and a degree of lung injury has been accepted as inevitable. The current trend toward increasing use of permissive hypercapnia is based on the recognition that lung injury induced by mechanical ventilation may be reduced by compensated hypercapnia with few serious adverse effects and contraindications.

Review Case Reports
Carotid artery pseudoaneurysm and pellet embolism to the middle cerebral artery following a shotgun wound of the neck.
Arterial missile embolism is a rare complication of penetrating vascular trauma. We report a case of middle cerebral artery pellet embolism and delayed appearance of a carotid artery pseudoaneurysm following a shotgun wound of the neck. The pseudoaneurysm was repaired. ⋯ He remains well 4 years after injury. A selective approach to the management of a pellet embolus to the middle cerebral artery based on clinical signs or symptoms and status of arterial patency is recommended. In addition, several principles are suggested to improve the reliability of arteriography for shotgun wounds of the neck.
