Friction, capacitance and transepidermal water loss (TEWL) in dry atopic and normal skin 总被引:2,自引:0,他引:2

The biophysical properties of non-eczematous skin at three locations in atopics and non-atopics were characterized using non-invasive physical methods. Skin friction was measured with a newly developed sliding friction instrument, the degree of hydration with a capacitance meter (Corneometer CM 820), and the transepidermal water loss (TEWL) was determined using an Evaporimeter EP1. The areas examined (dorsum of the hand, volar forearm and lower back) showed lower values of friction and capacitance in the atopic patients than did corresponding sites in the normal controls. In most areas a significant correlation between friction and capacitance was found. The TEWL was increased in atopic skin, but TEWL seems to correlate neither to friction nor to capacitance. 相似文献

Intracorporeal suturing is essential to advanced laparoscopy and is a rate-limiting step in many procedures. We have outlined an improved method of intracorporeal knot tying which is easier to learn, faster, and more consistently performed than current methods. Conventional intracorporeal knot-tying technique was compared to the knit-stitch method by ten volunteer surgeons. Each participant tied ten conventional-style knots in a video trainer. Surgeons were then taught the knit-stitch method and tied an additional ten knots. Knot-tying times were recorded and compared. Participants were asked to choose the method they preferred. The knit-stitch method was demonstrated to be faster than the conventional method for all participants, regardless of level of training or laparoscopic expertise (mean 63±19 vs 97±48 s; P<0.001). The difference was most marked in participants with the least laparoscopic suturing experience. The knit-stitch was preferred by 90% of the surgeons. Reasons cited for this preference were ease of learning, conservation of instrument motion, better utilization of the nondominant hand, and ability to work with shorter suture.Knit stitching is a faster, more consistent method of intracorporeal suturing. It is preferred because of its simplicity, efficiency, and potential to further reduce tissue trauma during the course of laparoscopic suturing. 相似文献

Background: Laparoscopic adrenalectomy has recently been shown to be a safe and effective means of treating adrenal pathology with much
lower morbidity than the traditional approach. The majority of reports in the literature involve removal of adrenal tumors.
Although open bilateral adrenalectomy has been utilized for persistent Cushing's syndrome following attempted hypophysectomy,
there is little data available describing the application of laparoscopic adrenal surgery to this problem.
Methods: Four patients with persistent Cushing's syndrome after attempted treatment with hypophysectomy underwent laparoscopic bilateral
adrenalectomy at our institution. One procedure was done transabdominally in the supine position. Three procedures were done
transabdominally using sequential lateral decubitus positions.
Results: All procedures were completed laparoscopically. The mean operative time was 4.6 h (range 3.9–5.25). Repositioning and reprepping
the patients resulted in a slight increase in operative time, but visualization was improved using the lateral decubitus position.
Average blood loss: 156 cc (range 50–300). One patient required early reoperation for bleeding from the left adrenal bed,
which was controlled laparoscopically. Three patients were eating the following day and were discharged on postoperative days
1, 2, and 5. The fourth patient remained hospitalized for 18 days due to problems unrelated to surgery. After a mean follow-up
of 10 months, all patients have done well and have no clinical or biochemical evidence of recurrent disease.
Conclusion: Our clinical experience indicates that laparoscopic bilateral adrenalectomy is a viable treatment option for Cushing's syndrome
following failed hypophysectomy.
