X-ray Follow-up after Open Reduction Internal Fixation of Distal Forearm Fracture.

 Following surgery, the standard regimen for fractures of the distal forearm includes radiographs taken 2-weeks postoperatively. However, it is unclear whether these radiographs have any therapeutic risks or benefits for patients.  The purpose of this study is to determine the importance of radiographs taken 2-weeks after surgery on distal forearm fractures, especially if it leads to further operations, and to establish whether this practice should be continued.

Low Recurrence Rate and Risk of Distant Metastases following Marginal Surgery of Intramuscular Lipoma and Atypical Lipomatous Tumors of the Extremities and Trunk Wall.

Objective: The purpose of the present study was to determine the local recurrence rate, risk of dedifferentiation, and distant metastasis after surgical excision of intramuscular lipomas (IML) and atypical lipomatous tumors (ALT).

Subjects And Methods: We retrospectively assessed all IML and ALT surgically removed from the extremities or trunk wall in our clinic between 1997 and 2006. Data from 141 patients with IML and 35 patients with ALT were extracted from the National Pathology Registry and patient files.

Effect of hyperglycemia and hyperinsulinemia on the response of IL-6, TNF-alpha, and FFAs to low-dose endotoxemia in humans.

Insulin therapy to maintain euglycemia increases survival in critically ill patients. To explore possible mechanisms of action, we investigated the effect of endotoxin on circulating cytokines, free fatty acids (FFA), and leukocytes during manipulated plasma glucose and insulin concentrations. Ten volunteers underwent three trials each, receiving an intravenous bolus of endotoxin (0.

Interleukin-6 production by contracting human skeletal muscle: autocrine regulation by IL-6.

Interleukin-6 (IL-6) is a cytokine with immuno-regulatory functions. However, contracting skeletal muscle expresses and subsequently releases IL-6 in high amounts, and recent evidence in IL-6 deficient mice suggests a role of IL-6 in metabolism. Since IL-6 mRNA levels also increase in abdominal adipose tissue in response to exercise, we wanted to examine the possible existence of a positive feedback mechanism between muscle and adipose tissue.

Immunohistochemical detection of interleukin-6 in human skeletal muscle fibers following exercise.

Interleukin-6 (IL-6) is produced by many different cell types. Human skeletal muscles produce and release high amounts of IL-6 during exercise; however, the cell source of origin in the muscle is not known. Therefore, we studied the protein expression of IL-6 by immunohistochemistry in human muscle tissue from biopsies obtained at time points 0, 3, 4.

Exercise and IL-6 infusion inhibit endotoxin-induced TNF-alpha production in humans.

During "nondamaging" exercise, skeletal muscle markedly releases interleukin (IL)-6, and it has been suggested that one biological role of this phenomenon is to inhibit the production of tumor necrosis factor (TNF)- alpha, which is known to cause pathogenesis such as insulin resistance and atherosclerosis. To test this hypothesis, we performed three experiments in which eight healthy males either rested (CON), rode a bicycle for 3 h (EX), or were infused with recombinant human IL-6 (rhIL-6) for 3 h while they rested. After 2.
