[EX Q]: Abstract: Pain thresholds to a pinch stimulus were measured at eight sites on the dorsum of both feet from 17 diabetic patients. Sixteen feet had neuropathic ulcers and seven had Charcot arthropathy. Vibration perception thresholds, radial nerve action potentials, muscle action potentials of flexor digitorum brevis, autonomic cardiovascular reflexes and reflex sweat output were also measured. Pinch pain threshold was abnormal in 15 diabetic feet, 11 having one or more insensitive sites. There was a greater variability in threshold between sites tested in diabetic than control subjects.

[EX Q]: Abstract: This study explores the relationship between exposure to a comprehensive worksite health promotion program and health care costs and utilization. The experience of two groups of Johnson & Johnson employees (N = 5192 and N = 3259) exposed to Live for Life, a comprehensive program of health screens, life-style improvement programs, and worksite changes to support healthier life-styles, was compared with that of a control group (N = 2955) over a five-year period. To account for baseline differences, analyses of covariance produced adjusted means for inpatient hospital costs, admissions, hospital days, outpatient costs, and other health costs. Mean annual inpatient cost increases were $43 and $42 for two Live for Life groups vs $76 for the non-Live for Life group. Live for Life groups also had lower rates of increase in hospital days and admissions. No significant differences were found for outpatient or other health care costs.

[EX Q]: Abstract: Ex vivo renal artery surgery has been reported by several investigators and has extended the role of revascularization in the treatment of lesions previously managed by nephrectomy alone. Several techniques are available for use, and selection of the most appropriate method can be tailored to the specific anatomy being managed. Our total experience included 27 kidneys that have been managed by ex vivo renal artery reconstruction. Lesions managed in this manner include two kidneys with renal artery stenosis and renal tumors, one kidney with a congenital branch arteriovenous malformation, and 24 kidneys with branch occlusive or aneurysmal disease from fibromuscular dysplasia. Postoperative angiography was performed in 22 cases and defined successful revascularization without technical error in 20 cases. One operative death occurred as a result of myocardial infarction. One patient required reoperation to control bleeding, and two patients had temporary acute tubular necrosis during the postoperative period. Techniques employed included ex vivo repair with autotransplantation to the iliac system (six kidneys), mobilization and perfusion without transection of the renal vein (10 kidneys), and ex vivo perfusion and repair with replacement into the original renal fossa (11 kidneys). The authors believe this latter technique of reconstruction to be preferable to autotransplantation for the usual patient undergoing ex vivo repair of complex renovascular lesions.
