Use of rhomboid flap and double Z-plasty technique in the treatment of chronic postburn contractures.

BACKGROUND: Multiple reconstructive methods have been used for the treatment of postburn scar contractures including skin grafting, geometric relaxation techniques, local flaps and free flaps. PURPOSE: In the present study, the authors evaluated efficiency of the use of rhomboid flap and double Z-plasty technique in the treatment of chronic postburn contractures. METHODS: Twelve white male with postburn scar contracture were treated using rhomboid and double Z-plasty technique. The cause of burn, duration of contracture, postoperative follow-up period, preoperative and postoperative motion lag of joints and improvement in motion were recorded. CONCLUSIONS: All operations were successful. Severe contracture lines crossing flexion folds can be released effectively by using rhomboid flap and double Z-plasty technique without distorting the specialized flexion areas and with broken scar lines which is essential to avoid from recurrence.

Use of free dorsoulnar perforator flap in the treatment of postburn contractures of the fingers.

BACKGROUND: Burns of the hand cause not only the impairment of hand function but also cosmetic deformity. Cases with dysfunctional hands with severe contractures increase if rehabilitation of the acutely burned hand is not done properly. PURPOSE: We present the use of free dorsoulnar perforator flap in the treatment of postburn contractures as an alternative when local flaps cannot be used. METHODS: Free dorsoulnar perforator flap was used in the treatment of seven hands with postburn contracture. Five of them had multiple digital postburn flexion contractures. Combined use of cross-finger and side finger transposition flaps was preferred when the adjacent finger was suitable for being cross-finger flap donor. When the adjacent finger was not suitable for being cross-finger flap donor, the free dorsoulnar perforator flap was preferred. Two of the patients had postburn web contractures. Free dorsoulnar perforator flap was used to release the web and to form a new web commissure. CONCLUSION: The free dorsoulnar perforator flap could be a good alternative to cover the defects created with the hand contracture release.

Camouflage of self-inflicted razor blade incision scars with carbon dioxide laser resurfacing and thin skin grafting.

BACKGROUND: Self-cutting using a razor blade is a type of self-mutilating behavior that leaves permanent and socially unacceptable scars with unique patterns, particularly on the upper extremities and anterior chest wall. These scars are easily recognized in the community and become a source of lifelong guilt, shame, and regret for the self-mutilators. In the presented clinical study, we aimed to investigate the effectiveness of carbon dioxide laser resurfacing and thin skin grafting in camouflaging self-inflicted razor blade incision scars. METHODS: A total of 26 anatomical sites (11 upper arm, 11 forearm, and four anterior chest) of 16 white male patients, whose ages ranged from 20 to 41 years (mean, 23.8 years), were treated between February of 2001 and August of 2003. Detailed psychiatric evaluation preoperatively; informing the patient that the procedure is a "camouflage" operation; trimming hypertrophic scars down to intact skin level; intralesional corticosteroid injection to hypertrophic scars; carbon dioxide laser resurfacing as a single unit; thin (0.2 to 0.3 mm) skin grafting; compressive dressing for 15 days; use of tubular bandage; and protection from sunlight for at least 6 months constituted the key points of the procedure. RESULTS: The scars were successfully camouflaged and converted to a socially acceptable appearance similar to a burn scar. Partial graft loss in one case and hyperpigmentation in another case were the complications. No new hypertrophic scar developed. CONCLUSIONS: The carbon dioxide laser resurfacing and thin skin grafting method is effective in camouflaging self-inflicted razor blade incision scars.

Nerve regeneration through a healthy nerve trunk: a new and hopeful conduit for bridging nerve defects.

BACKGROUND: Considering a healthy nerve trunk as the hypothetically ideal conduit, a new experimental model using an intact nerve for bridging a nerve defect was contemplated. METHODS: Thirty rats were used. In group I (double coaptation), a segment was removed from the peroneal nerve. Both the proximal and distal stumps were repaired end-to-side to the tibial nerve. In group II (only distal coaptation), only the distal nerve stump was repaired. In group III (control), the transected segment was immediately repaired primarily in its original orientation as a nerve graft. A walking track analysis was conducted periodically for 28 months. The horseradish peroxidase retrograde labeling technique was used for tracking the origin of the axons presented in the distal stump of the peroneal nerve in group I, and morphologic studies were also carried out for all the groups. RESULTS: Functional assessment revealed that the difference between group I and group II was significant. The horseradish peroxidase labeling test suggested that the nerve fibers in the distal stump of the peroneal nerve were mostly from its original proximal stump passed by the way of the tibial nerve bridge. CONCLUSION: This study suggested that the axons of the proximal stump of a sectioned nerve can sprout into another intact nerve trunk by the way of an end-to-side repair site, regenerate, and advance in its epineurium distally for a distance and pass into its original distal stump if it was repaired end-to-side. It was thought that the technique could be used in clinical cases with short nerve defects as an alternative method to grafts and conduits.

Carbon dioxide laser therapy for an inflammatory linear verrucous epidermal nevus: a case report.

The treatment of an inflammatory linear verrucous epidermal nevus (ILVEN), an uncommon type of epidermal nevus, is still controversial. The use of laser therapy is a recently reported method. Although various results have been reported with the use of the laser in the treatment epidermal nevis, the authors have not seen any report on the use of the carbon dioxide laser in ILVEN treatment. They present case of ILVEN treated with the carbon dioxide laser. All symptoms (erythema, excoriation, granulation, and pruritus) disappeared. Instead, a pale pigmentation was seen.

Carbon dioxide laser resurfacing and thin skin grafting in the treatment of "stable and recalcitrant" vitiligo.

Various surgical methods have been used in the treatment of small stable vitiliginous areas, but there is no established surgical approach for larger vitiligo areas and therapy-resistant anatomic sites, such as the hands. Two years ago, we successfully treated large burn scar depigmentation areas at different anatomic sites using carbon dioxide laser resurfacing and thin (0.2 to 0.3 mm) skin grafting. The purpose of this study was to investigate the effectiveness of our method in treating large, stable, and recalcitrant vitiligo areas. Thirteen anatomic sites of seven male patients, whose ages ranged from 20 to 22 years, were treated. The locations of the treated areas were as follows: seven areas on the dorsum of the hands, two areas on the forearms, two areas in the pretibial region, one area on the lateral thigh, and one area in the presternal region. The surface area of treated vitiligo sites ranged from 0.5 to 6 percent of total body surface area (mean, 2.5 percent). Skin graft take was excellent in all patients except for one. The follow-up period for these patients ranged from 6 to 18 months, with an average follow-up period of 14 months. Early and complete repigmentation was achieved and the color match was good or excellent in all patients. No depigmentation occurred again in the treated areas or graft donor sites. In conclusion, with careful patient selection and delicate surgical technique, our method was effective in treating large areas of vitiligo over the extremities and dorsum of hands, which were refractory to other therapies and could not be hidden.

Bilateral side finger transposition flaps in the treatment of chronic postburn flexion contractures of the fingers.

The authors present a surgical method of releasing postburn flexion contracture of the finger by two separate transverse incisions and covering the skin defects by transposing two random-pattern flaps from both sides of the finger. One of the proximally based flaps was transposed from one side of the proximal phalanx and the other flap was transposed from the opposite side of the middle phalanx. Because the flaps were raised from different sides of different phalanxes, the donor sites were closed primarily. A total of 37 fingers (14 hands, 11 patients) were treated with this method. The patients were all men aged 20 to 24 years old. The mean follow-up period was 9 months. The lack of extension of the proximal interphalangeal joints of the fingers was improved by approximately 45 deg using the described method. The authors conclude that this method can be used effectively in the treatment of mild to moderate postburn flexion contractures of the fingers.

Comparison of silver sulfadiazine 1%, mupirocin 2%, and fusidic acid 2% for topical antibacterial effect in methicillin-resistant staphylococci-infected, full-skin thickness rat burn wounds.

Silver sulfadiazine 1%, mupirocin 2%, and fusidic acid 2% were compared to assess the antibacterial effect of a once-daily application on experimental rat 15% full-skin thickness burn wounds seeded 24 hours earlier with a 10 standard strain of methicillin-resistant staphylococci. The quantitative counts of seeded organism in burn eschar and subjacent muscle were determined at postburn day 7, beside the cultures of blood and lung biopsies. All tested topical agents were equally effective against methicillin-resistant in reducing local burn wound bacterial count and preventing systemic infection.
