Nonablative resurfacing.

Abstract

Nonablative, or subsurface remodeling, is the newest approach to improving photodamaged skin. Because the degree of collagen remodeling is not as great as that of other, more destructive ablative approaches, the process can be ideal for individuals with limited time, wishing to improve (with lasers) the quality of their sun-damaged skin. In addition, nonablative laser systems may be used to maintain the rejuvenating effect of ablative laser systems.

Primary giant cell tumor of soft tissue.

BACKGROUND: Primary giant cell tumor of soft tissue, also known as soft tissue giant cell tumor of low malignant potential, is a rare soft tissue tumor located in both superficial and deep soft tissue. Histologically, these lesions bear a close resemblance to their bony counterparts, giant cell tumor of bone, with round to spindle-shaped cells intimately admixed with uniformly scattered osteoclast-like multinucleated giant cells. In 1989 in the dermatology literature, two malignant giant cell tumors of soft parts were described that filled the dermis and extended into the subcutaneous tissue. METHODS: The authors report the rare occurrence of a giant cell tumor of soft tissue occurring primarily in the dermis that lacks overtly malignant features and clinically was thought to be an epidermal inclusion cyst. RESULTS: Light microscopy revealed a non-encapsulated cellular dermal tumor containing numerous osteoclast-like giant cells. Cytologic atypia was minimal and the mitotic count averaged 2-3/10 HPF. The histologic differential diagnosis is also discussed. CONCLUSION: Giant cell tumor of soft tissue is a rare neoplasm of the skin, however, recognition of this tumor is important due to its behavior as a low-grade malignancy.

Iron concentrations in human dermis assessed by microdialysis associated with atomic absorption spectrometry.

Until recently, the determination of metallic elements concentrations in normal skin, in vivo, was rare due to the lack of non-invasive techniques. Microdialysis has the advantage of being slightly invasive when applied to the collection in vivo of endogenous or exogenous substances from the skin. Iron is an active element in different cutaneous disorders. The aim of this work was to assess iron by atomic absorption spectrometry (AAS) after the collection of samples by microdialysis from human dermis. A first essential step, before determining the in vivo iron concentration in human dermis, was to establish an experimental protocol applicable to ex vivo as well as in vivo conditions. For this reason, this work deals only with the assessment of iron in ex vivo human dermis. A skin microdialysis technique and a calibration method, the No Net Flux, were used to quantify basal iron concentrations in human dermis and the same method was also used to determine in vitro and ex vivo iron recoveries. No differences were detected between in vitro and ex vivo recoveries. Ex vivo basal iron dermis concentrations ranged from 3.6 to 7.7 microg/l. This study shows that non-invasive microdialysis is an efficient method for sampling iron from human skin. A sensitive and accurate AAS technique was able to assess low iron concentrations in human dermis. The strategy adopted for this work was efficient and appropriate for the determination of iron in human skin and experiments will be carried out in vivo.

Male slings for postprostatectomy incontinence.

PURPOSE: Over the past few years, there has been increasing interest in using male slings for postprostatectomy incontinence (PPI). Currently, three different forms of the male sling has been described: one using synthetic materials and two using human fascia or dermis. This article will give a historical perspective on the male sling and describe the surgical techniques and early results using two different types of male slings using fascia or dermis. MATERIALS AND METHODS: From 1997 to 1999, nine patients with PPI underwent a bladder neck sling procedure using a combined perineal and abdominal approach. All patients had a suprapubic incision to expose the rectus muscle and to place a suprapubic tube. Since 1999, we have used a wide cadaveric fascial or dermal sling placed at the proximal bulbar urethra. Using an entirely perineal approach, the sling ends are fixated to the inferior pubic rami using bone anchors. RESULTS: Of 9 patients with bladder neck slings, 6 are dry, 1 is significantly improved, and 2 have failed, at a mean follow-up of 13 months. For the perineal male sling, 26 (45%) of 58 patients were completely dry, and overall 47 (81%) of 58 were significantly improved or were dry at a mean 6 months postoperatively. Neither group had significant complications. CONCLUSIONS: Both male slings appear to be safe and effective procedures for treating PPI; however, longer follow-up and additional experience are needed to determine their true role in the treatment of PPI.
