Trans-axillary retro-mammary gland route approach of video-assisted breast surgery can perform breast conserving surgery for cancers even in inner side of the breast / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The endoscopic surgery for inner-side cancer of the breast is usually performed by periareolar approach, but it often makes deformation or malposition of nipple and areola. The trans-axillary approach is favorable without making any injuries on breast skin. Furthermore, we devised a new approach of retro-mammary route without subcutaneous exfoliation, from axillary skin incision, to preserve skin touch sensation.</p><p><b>METHODS</b>We have performed video-assisted breast surgery (VABS) on 200 patients since December 2001. The newly devised trans-axillary retromammary-route approach (TARM) was performed on 12 patients of early breast cancer. After endoscopic sentinel lymph node biopsy, we lengthened the axillary skin incision to 2.5 cm, and dissected retromammary tissue from superficial pectoral fascia onto major pectoral muscle below the tumor. The working space was made by lifting traction sutures through the gland. We cut the gland vertically at free margin 2 cm apart from the tumor edge, and dissect skin flap over the tumor. The breast reconstruction was done by filling absorbable fiber cotton.</p><p><b>RESULTS</b>Traction sutures made it easier to cut the mammary gland vertically. We did not experience any skin damages like burn. All surgical margins were negative. The operation time was needed longer but the blood loss was not different. The postoperative esthetic results were good. The sensory disturbance was minimal. All patients were satisfied with this operation.</p><p><b>CONCLUSION</b>This newly devised TARM approach need no injury on whole breast, and can become a single standard method for breast conserving surgery wherever the cancer situated.</p>

Comparison of Fourth-year Comprehensive Examinations and Computer-based Testing in the Nationwide Medical and Dental Student Evaluation System / 医学教育

To demonstrate the quality assurance of comprehensive examinations for fourth-year students at Nippon Medical School, scores on comprehensive examinations were compared with those on a trial of computer-based testing (CBT) of a nationwide medical and dental student evaluation system in 2003. Pearson's correlation coefficients between scores of two comprehensive examinations and the CBT score were 0.45 and 0.67, and the correlation coefficient between the average score of the two comprehensive examinations and the CBT score was 0.55. Fourth-year comprehensive examinations are useful tools for summative evaluation and prediction of CBT performance.

A Comparative Study of Undergraduate Examinations to Evaluate Medical Students' Performance and the National Examination for Medical Practitioners / 医学教育

To demonstrate the quality assurance of the comprehensive examination of sixth-year students at Nippon Medical School, 4 undergraduate examinations were compared with the national examination for medical practitioners (NEMP) using scatter graphs and Pearson's correlation coefficient. Of the 93 sixth-year students at Nippon Medical School, 57%(n=53) reported their scores on the NEMP in response to a request from the Academic Quality and Development Office. Correlation coefficients of the grade point average (years 1 to 5), average scores on graduation examinations of 24 subjects, scores on the trial examination of NEMP, and scores on the sixth-year comprehensive examination with overall scores on the NEMP were 0.62, 0.46, 0.68, and 0.63, respectively. These results suggest that the sixth-year comprehensive examination is more suitable than are graduation examinations for predicting the NEMP score.
