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: Information obtained for all persons with the acquired immunodeficiency syndrome (AIDS) reported to the Centers for Disease Control, Atlanta, includes a question about employment in a health care or clinical laboratory setting. As of May 1, 1986, a total of 922 (5.5%) of 16,748 adults with AIDS reported employment in such settings. Ninety-five percent of these health care workers belonged to recognized high-risk groups for AIDS; the proportion with "no identified risk" has not increased with time. All AIDS patients (including health care workers) who do not belong to high-risk groups are referred for further investigation. Of 88 health care workers initially reported with no identified risk, ten were from countries where heterosexual transmission is believed to play a major role; additional information was unobtainable or incomplete for 17 individuals. Of 61 persons on whom interviews or other follow-up information was obtained, 44 (73%) were reclassified. Specific occupational exposures that could be implicated as the source of human immunodeficiency virus infection were not identified for any health care workers with AIDS. A review of surveillance data supports other studies indicating that the risk of human immunodeficiency virus transmission in the occupational setting is low.

Abstract: Thrombospondin with fibrinogen, fibronectin, and von Willebrand factor binds to platelets stimulated with agonists and support platelet adhesive functions. The receptors for the latter three proteins are associated with membrane glycoprotein GPIIb-IIIa. Thrombasthenic platelets deficient in GPIIb-IIIa have been utilized to examine the role of this membrane protein in the interactions of thrombospondin with platelets. Radioiodinated thrombospondin bound to thrombin-stimulated platelets from normal and thrombasthenic donors with a similar affinity and capacity. As monitored with a monoclonal antibody to thrombospondin, the divalent ion-dependent and -independent pathways for the expression of the endogenous pool of thrombospondin on the surface of thrombin-stimulated platelets from normal and thrombasthenic donors were also qualitatively and quantitatively similar. GPIIb-IIIa or ligands associated with GPIIb-IIIa thus are not essential for the binding of thrombospondin to platelets. Therefore, thrombospondin interacts with unique receptors on platelets.
