A new once-a-day fentanyl citrate patch (Fentos Tape) could be a new treatment option in patients with end-of-dose failure using a 72-h transdermal fentanyl matrix patch.

Purpose: The recommended dosing interval for transdermal fentanyl is every 72 h. However, some patients will have "end-of-dose failure," which may be seen as an increase of episodes of severe pain flares at the third day after application of the patch. A new once-a-day fentanyl patch was developed in Japan since 2010.

Autocrine production of epithelial cell-derived neutrophil attractant-78 induced by granulocyte colony-stimulating factor in neutrophils.

Whereas mobilization to inflammatory sites is an important function of neutrophils, it remains to be determined whether granulocyte colony-stimulating factor (G-CSF) stimulates the mobilization of neutrophils to the inflammatory sites. This study compared the expression of more than 9000 genes in neutrophils treated with and without G-CSF with the use of a DNA microarray system to determine the effects of G-CSF on the function of neutrophils. It was found that messenger RNA expression of epithelial cell-derived neutrophil attractant-78 (ENA-78), which has been reported to be a chemotactic factor for neutrophils, was induced by G-CSF in neutrophils.
