Endoscopic tattooing of the colon: clinical experience.

Abstract: Nonpalpable lesions of the colon can be difficult to locate intraoperatively. We have demonstrated in an experimental study in dogs that the colon can be endoscopically "tattooed" by injecting dye through a flexible needle into the wall of the colon. At laparotomy, the resulting "tattoo" is then visible on the serosal surface of the bowel. This technique allows precise surgical localization of endoscopically identified lesions simply by visualizing the dye. Our initial clinical experience tattooing 15 colonic lesions in 12 patients is presented. In all patients, the endoscopically injected dye (1 per cent indocyanine green) was easily visualized on the serosal surface of the colon at surgery. The dye remained at the site of injection for at least 36 hours allowing tattooing to be performed the day before surgery. No significant complications were encountered with only one patient developing an inflammatory reaction at the site of injection. This experience demonstrates the clinical utility of endoscopic tattooing of the colon to permit accurate intraoperative localization of small or nonpalpable lesions.

Mammographic distance as a predictor of nipple-areola complex involvement in breast cancer

Abstract: Background Although involvement of the nipple-areola complex (NAC) occurs in a minority of patients with breast cancer, standard skin-sparing mastectomy requires its removal. To assist in patient selection for NAC preservation we evaluated NAC involvement and correlated this with preoperatively available clinical data. Methods Patients with invasive breast cancer or ductal carcinoma in situ undergoing mastectomy from 1998 to 2005 were reviewed retrospectively. The NAC had been evaluated with multiple thin sections. Pathologic data including NAC involvement were analyzed. The mammographic tumor distance from the nipple was measured in 2 standard views. Results There were 302 patients enrolled, of which 10% were noted to have NAC involvement. This correlated negatively with tumor distance from the nipple ( P Conclusions A majority of patients are candidates for NAC preservation. The mammographic distance between the tumor and the nipple is independently predictive of NAC involvement and is useful as an equation variable.

Factors affecting the performance of entrepreneurial service firms

Abstract: In the current climate, the importance of the role played by entrepreneurship as a palpable reality that enables economic growth at a macroeconomic level, and as a factor that favours the progress of companies at a microeconomic level, has made it the subject of continual analyses from many different perspectives and in a variety of contexts by researchers from around the world. In this study, Spanish entrepreneurial firms in the service sector are analysed in order to determine the factors that influence their performance.
