The prevalence of carotid and lower extremity arterial disease was assessed in a healthy population of 56 elderly adults with isolated systolic hypertension. Duplex scans were performed to determine the extent of carotid disease, and postexercise ratios of ankle to arm systolic blood pressure were measured to assess lower extremity arterial disease. Internal carotid stenosis was found in 38% (2...

It has been hypothesized that cutaneous melanoma at different anatomic sites develops through divergent pathways. We examined this hypothesis prospectively. We followed 152,949 women and 25,204 men free of cancer at baseline for up to 14 years in three large prospective studies. We examined risk factors for melanoma by anatomic location (head or neck, trunk, upper extremity, and lower extremity...

PURPOSE To determine the frequency of pelvic varicose veins with transvaginal ultrasound and associated lower extremity venous insufficiency with Doppler ultrasound in women with chronic pelvic pain of undetermined origin. MATERIALS AND METHODS A total of 100 women with chronic pelvic pain of undetermined origin lasting more than 6 months were included in the study. The presence of anechogeni...

PURPOSE The lower extremity has received its fair share of attention as a vascular access site in patients who have exhausted their upper arm vessels. However, experiences with lower extremity arteriovenous grafts (AVGs) have so far been disappointing because of high infection rates and severe limb ischemia. We report our experience with hemodialysis access from the lower extremity. MATERIALS...

OBJECTIVE To evaluate in a preliminary manner the feasibility, safety, and efficacy of Constraint-Induced Movement therapy (CIMT) of persons with impaired lower extremity use from multiple sclerosis (MS). DESIGN Clinical trial with periodic follow-up for up to 4 years. SETTING University-based rehabilitation research laboratory. PARTICIPANTS A referred sample of ambulatory adults with chr...

The lower-extremity vascular injuries and neuropathy are the most salient complications of diabetes which could lead to the poor prognosis, especially for the type II diabetes. The lower extremity vascular injuries and neuropathy usually coexist, yet their correlation in the pathogenesis of lower extremity lesions has received little attention in previous studies. To investigate the correlation...

BACKGROUND We sought to identify risk factors associated with mortality following surgery for peripheral arterial disease (PAD). METHODS We evaluated the association between levels of control of atherosclerotic risk factors and time to mortality following either lower extremity bypass surgery or lower extremity amputation using Cox proportional hazards regression. RESULTS Among 796 patients...

BACKGROUND AND PURPOSE Complex regional pain syndrome (CRPS) is a challenging complication after surgery or trauma. This study sought to determine the incidence of CRPS after a second inciting event in a previously unaffected extremity in patients with a history of an ongoing CRPS diagnosis in another extremity. METHODS A retrospective review identified patients with CRPS seen in clinic over ...

CONTEXT A discrepancy in anterior cruciate ligament (ACL) injury rates exists between men and women. Structural differences between the sexes often are implicated as a factor in this discrepancy. Researchers anecdotally assume that men and women tend to display different normative values for certain lower extremity alignments, but published information about these values is limited. OBJECTIVE...

BACKGROUND Chemoprophylaxis for venous thromboembolism (VTE) is considered standard of care after lower but not after upper extremity arthroplasty. Medicare claims data were analyzed to determine the national incidence of symptomatic VTE after shoulder arthroplasty during the index surgical admission and after discharge. METHODS Incidence of VTE was compared between shoulder arthroplasty and ...
