Randomized Controlled Trial Comparative Study Clinical Trial
Prospective randomized trial of carotid endarterectomy with polytetrafluoroethylene versus collagen-impregnated dacron (Hemashield) patching: late follow-up.
To compare the late clinical outcome and incidence of recurrent stenosis after carotid endarterectomy (CEA) with polytetrafluoroethylene (PTFE) versus Hemashield patching. ⋯ PTFE patching was superior to Hemashield in lowering the incidence of postoperative ipsilateral strokes and late recurrent stenosis.

The evolution of nonoperative management of certain solid visceral injuries has stimulated speculation that management of the severely injured child is no longer a surgical exercise. The authors hypothesized that the incidence of injuries that require surgical evaluation is disproportionately high in children at risk of death or disability from significant injury. ⋯ These data clearly demonstrate the primacy of surgical pathology as the major determinant of outcome in pediatric injury. Operative intervention and the option of timely operative care remain major components of clinical management of children with injuries that pose a significant risk of morbidity or mortality.

Comparative Study
The LEGS score: a proposed grading system to direct treatment of chronic lower extremity ischemia.
To prospectively compare the Lower Extremity Grading System (LEGS)-derived "recommended treatment" to the actual treatment performed and to analyze LEGS intergrader scoring consistency by comparing blinded scoring results between physician graders. ⋯ A reproducible scoring system to guide the treatment of patients with chronic lower extremity ischemia is possible. While systems like the LEGS score may have potential clinical application, their use as a treatment standardization tool for future prospective outcomes comparisons between open and endovascular surgery will be essential.

To describe a novel in vitro human tissue-based angiogenic model that can predict an individual tumor's response to antiangiogenic drugs. ⋯ Epothilone B may be an effective antiangiogenic agent in a variety of tumor types. The authors speculate that this in vitro model might provide useful information to the clinician on the effect of specific antiangiogenic agents on individual tumors. This may be particularly useful in patients with tumors that, as a group, are unresponsive to treatment with antineoplastic agents.

To restore islet function in patients whose labile diabetes subjected them to frequent dangerous episodes of hypoglycemic unawareness, and to determine whether multiple transplants are always required to achieve insulin independence. ⋯ This report confirms the efficacy of the Edmonton immunosuppressive regimen and indicates that insulin independence can often be achieved by a single transplant of sufficient islet mass.
