Expression of the P450arom mRNA in the glandular tissue of the pubertal mammary hypertrophy / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the expression status of the P450arom mRNA in breast tissue of pubertal mammary hypertrophy and then explore the possible etiology of pubertal mammary hypertrophy.</p><p><b>METHODS</b>15 patients were selected for pubertal mammary hypertrophy group. Breast hypertrophy tissue specimens were collected from the gland excised during reduction mammaplasty. 15 patients with pathologically simple fibroadenoma were used as another control group. Patient approval of participation in this study was obtained preoperatively. The expression of P450arom mRNA was detected by RT-PCR in all the cases above.</p><p><b>RESULTS</b>There was no significant difference between the pubertal mammary hypertrophy groups and normal groups on the expression rates of P450arom mRNA. But among the positive cases, the expression of P450arom mRNA within breast tissue were 0.202 +/- 0.048 in pubertal mammary hypertrophy group; and 0.159 +/- 0.068 in normal group. There was significant difference between the pubertal mammary hypertrophy and normal groups (P < 0.05).</p><p><b>CONCLUSION</b>The expression of P450arom mRNA in pubertal mammary hypertrophy are significantly higher than in normal mammary glandular tissue. The pubertal mammary hypertrophy may be related to the expression status of P450arom mRNA within breast tissue.</p>

Reduction mammaplasty with the superomedial glandular pedicle / 中华整形外科杂志

<p><b>OBJECTIVE</b>To explore a new technique that keep function and good aesthetic shape after reduction mammaplasty.</p><p><b>METHODS</b>The superomedial glandular pedicle technique was applied with differing patterns of skin incision according to the degree of the mammary hypertrophy. The extra glandular tissue was removed from the lateral and inferior segment of the breast. The remaining superomedial glandular tissue was remodeled a conical shape. The skin incision was sutured after excision of excess skin.</p><p><b>RESULTS</b>36 cases (72 breasts) were treated with this technique. The results were satisfactory and there were no complications. The breasts maintained a lasting and aesthetically pleasing shape and the nipple-areola preserved good sensation.</p><p><b>CONCLUSIONS</b>The superomedial glandular pedicle is a safe and effective technique that can provide long-lasting outcome. The design of the procedure can be adapted to a variety of skin incision patterns and breast morphologies.</p>
