Abstract: Surgical management of major venous injuries remains controversial. The medical records of 184 patients with major venous injury were reviewed. Forty-three patients had isolated venous injury; 31 of 43 patients (72%) underwent ligation to treat their vein injury. Another 141 patients had combined arterial and venous injury; 117 of these patients (83%) had ligation. Injured were the inferior vena cava, iliac, femoral, popliteal, distal leg, and arm veins; all patients underwent surgical exploration. Arterial injuries were repaired by standard techniques and venous injuries were either ligated or repaired by end-to-end or lateral phleborrhaphy. Adjunctive fasciotomy was used when clinically indicated. The patients were followed up for 1 month to 9 years. No permanent sequelae of venous ligation were identified. Transient extremity edema developed in up to 32% of patients, regardless of whether vein ligation or repair was performed. This edema resolved completely within 12 weeks of the injury. No extremity was lost after ligation of a venous injury. Although it may be ideal to repair all venous vascular injuries, selective management reflecting mechanism of injury, blood loss, anesthesia requirements, associated organ injury, and other concerns may mitigate against extensive venous repair.

Abstract: The New Mexico State Legislature passed a child restraint law applicable to children less than 5 years of age that became effective in June 1983. To evaluate the effectiveness of this law, we analyzed traffic accident data for New Mexico from January 1981 through September 1984. During this period, there were 20,972 children younger than 5 years of age in motor vehicle accidents. Restraint usage increased for this age group from a low of about 10% in 1981 to more than 40% in 1984 (P less than 10(-6)). Unrestrained children younger than 5 years of age were five times more likely to be killed and two times more likely to be injured than restrained children. Analysis of motor vehicle accident fatality and injury rates pre- and post-law revealed a 33% reduction in motor vehicle accident fatality rates and a 12.6% reduction in nonfatal injury rates for children younger than 5 years. We conclude that child restraint devices are effective in reducing motor vehicle accident fatalities and injuries in young children and the child restraint law has been effective in increasing child restraint usage and in reducing childhood death and injury in New Mexico.

Abstract: We have induced a basophil hypersensitivity reaction in the upper tarsal conjunctiva of the guinea pig by methods that induce a comparable basophil hypersensitivity reaction in the flank. The inflammatory cell infiltrate in this reaction contained large numbers of basophils and eosinophils with accompanying neutrophils and monocytes. Ocular tissue can serve as a priming site for systemic immunization and also for elicitation of a secondary flare after challenge with antigen. Very few inflammatory cells were observed in the cutaneous epithelium of either primary or secondary flares. In contrast, the mucosal stroma and epithelium contained large numbers of inflammatory cells (basophils, eosinophils, and neutrophils), suggesting directed cellular movement onto the ocular surface. The lesion of ocular basophil hypersensitivity in the guinea pig has features in common with two human eye diseases, vernal conjunctivitis and contact lens-associated giant papillary conjunctivitis. We hypothesize that the acute basophil hypersensitivity reactions of the conjunctiva are transformed into chronic inflammatory and proliferative states in vernal conjunctivitis and giant papillary conjunctivitis.
