Extracorporeal Shock Wave Therapy for Hypertrophic Scars.

Background Hypertrophic scars cause aesthetic concerns and negatively affect the quality of life. A gold standard treatment for hypertrophic scars has not been established due to various responses of modalities. Extracorporeal shock wave therapy (ESWT) is a noninvasive and affects scar remodeling by fibroblast regulation. This study investigated the effectiveness of ESWT for hypertrophic scars. Methods Twenty-nine patients were enrolled. All patients underwent ESWT once a week for 6 consecutive weeks. Their scars were assessed using the Patient and Observer Scar Assessment Scale (POSAS), erythema index, melanin index, and scar pliability before treatment and again 4 weeks after treatment completion. Results Thirty-four hypertrophic scars in this study had persisted for between 6 months and 30 years. Most scars developed after surgical incision (55.88%). The chest and upper extremities were the predominant areas of occurrence (35.29% each). Most of the POSAS subscales and total scores were significantly improved 4 weeks after treatment ( p < 0.05). Furthermore, the pain, itching, and pigmentation subscale were improved. The pliability, melanin index, and erythema index were also improved, but without significance. The patients were satisfied with the results and symptoms alleviation, although subjective score changes were insignificant. No serious adverse events were found. The patients reported pruritus in 62.5% and good pain tolerance in 37.5%. Subgroup analyses found no differences in scar etiologies or properties at different parts of the body. Conclusion The ESWT is a modality for hypertrophic scar treatment with promising results. Most of POSAS subscales were significantly improved.

Autologous tissue reconstruction sternal cleft: a rare congenital malformation.

Sternal clefts are rare congenital chest-wall deformities, which can be complete or incomplete; therefore, reconstruction with autologous tissue is essential to protect the heart and prevent respiratory infection. In this report, we present the case of a 16-month-old baby girl from a preterm, twin pregnancy with a partial superior sternal cleft. A moist dressing for promoting wound healing was used until cutaneous layer complete epithelialization at which time we performed reconstruction with autologous tissue. After surgery the patient recovered with close-to-natural chest wall contour and adequate heart and lung function.

Prospective study of Q-switched Nd:YAG laser treatment of hyperpigmented split-thickness skin grafts.

Hyperpigmentation of split-thickness skin grafts (STSGs) is commonly found among Asians, and it is also challenging to treat. Although the 1064-nm Q-switched Nd:YAG laser has been used as a standard treatment for skin hyperpigmented lesions, there are limited number of reports focusing on the treatment of hyperpigmentation of STSGs. We aimed to evaluate the efficacy of 1064-nm Q-switched Nd:YAG laser for treatment of hyperpigmented STSGs. Half of each STSGs was treated with the 1064-nm Q-switched Nd:YAG laser, while the remaining was left untreated as comparison. The laser was applied for 4 times with 2-4-week interval. The treatment outcomes were compared by measurement of melanin index, erythema index, and photographs of STSGs at prior to enrollment, before each treatment session, and after 1 month of treatment completion. Five patients with 11 skin graft lesions were enrolled. The melanin index was significantly improved after the 2nd session and after treatment completion in laser-treated area (p = 0.006 and p = 0.001, respectively). There was non-significant difference in erythema index. The photographic comparison showed brightened of laser-treated area after treatment completion and improved skin texture. The 1064-nm Q-switched Nd:YAG laser can significantly reduce melanin index of STSGs and can be an alternative treatment for hyperpigmentation of STSGs.

Efficacy of Low-temperature Plasma for Treatment of Facial Rejuvenation in Asian Population.

BACKGROUND: Plasma, the fourth state of matter, has been widely proposed in antiaging medicine. The usage of low-temperature plasma (LTP), which converts nitrogen gas into plasma, demonstrates releasing of several growth factors and promotion of tissue regeneration. The nonchromophore-dependent property and preservation of skin architecture after treatment make LTP an interesting tool for facial rejuvenation. This study aimed to investigate the efficacy of LTP for facial rejuvenation. METHODS: A prospective cohort study involving 40 women who received full face LTP treatment once a week for 5 consecutive sessions. The melanin index, erythema index, and elasticity index were measured by Mexameter and Cutometer, respectively. The Fitzpatrick wrinkle scale and quartile grading scale were assessed by two plastic surgeons. RESULTS: All patients were between 26 and 55 years old and had mild-to-moderate Fitzpatrick wrinkle scale scores. The Fitzpatrick wrinkle scale scores showed a mean improvement of 0.47 and 0.89 at 4 and 12 weeks posttreatment (P < 0.001). Statistically significant improvements in melanin index, erythema index, and elasticity index at periorbital and perioral areas were found at 4 and 12 weeks after treatment (P < 0.001). Most subjects had quartile grading scale improvement of 51%-75% at 4 and 12 weeks after treatment. Patients reported a greater than 75% improvement in dyspigmentation, wrinkles, and elasticity in 60%, 50%, and 57.5% of subjects, respectively. CONCLUSION: LTP is another choice for facial rejuvenation, wrinkles reduction, and dyspigmentation with significantly improved results.

The Healing Effect of Low-Temperature Atmospheric-Pressure Plasma in Pressure Ulcer: A Randomized Controlled Trial.

Pressure ulcers are difficult to treat. Recent reports of low-temperature atmospheric-pressure plasma (LTAPP) indicated its safe and effectiveness in chronic wound care management. It has been shown both in vitro and vivo studies that LTAPP not only helps facilitate wound healing but also has antimicrobial efficacy due to its composition of ion and electron, free radicals, and ultraviolet ray. We studied the beneficial effect of LTAPP specifically on pressure ulcers. In a prospective randomized study, 50 patients with pressure ulcers were divided into 2 groups: Control group received standard wound care and the study group was treated with LTAPP once every week for 8 consecutive weeks in addition to standard wound care. We found that the group treated with LTAPP had significantly better PUSH (Pressure Ulcer Scale for Healing) scores and exudate amount after 1 week of treatment. There was also a reduction in bacterial load after 1 treatment regardless of the species of bacteria identified.

The efficacy of combined herbal extracts gel preparation in the prevention of postsurgical hypertrophic scar formation.

INTRODUCTION: The objective of preventing surgical scar formation is to improve the quality of life for patients. Many medical products have been used in preventing hypertrophic scarring but an optimal treatment method has not been established yet. At the present, there are several studies demonstrating the potential of herbs in scar prevention. The purpose of this study was to evaluate the efficacy of combined herbal extracts gel (CHG) in the prevention of surgical scar formation. METHODS: All the patients who underwent bilaterally symmetric surgical procedures were selected using inclusion and exclusion criteria and were then treated with both the CHG (CHG group) and placebo gel. Each gel was applied on separate scars twice daily for 12 weeks. The scars were photographed and evaluated using Patient and Observer Scar Assessment Scale (PSAS and OSAS, respectively). RESULTS: The CHG-treated scars showed lower median PSAS scores than the placebo group in color, stiffness, thickness, irregularity, and overall scores, with statistically significant difference at 12 weeks. For OSAS, the scars in the CHG group showed lower median scores than the placebo group in pigmentation, thickness, and overall scores at 12 weeks. The median OSAS scores in vascularity, relief, and pliability differed from placebo group and were statistically significant at 8 weeks. No side effects were observed in either group. CONCLUSION: The CHG might be effective in the prevention of surgical scarring.

Clinical Effectiveness of Hyperbaric Oxygen Therapy in Complex Wounds.

Hyperbaric Oxygen (HBO, HBO2) Therapy is a non-invasive therapy. It has been applied as adjuvant treatment in many medical conditions over the past 50 years. Different treatment protocols have been proven effective for specifically indicated conditions. To evaluate the clinical effectiveness of Hyperbaric Oxygen (HBO) Therapy as an adjunctive treatment for patients with complex wounds. In this prospective cohort study, 40 patients with complex wounds were included. All patients received HBO. HBO was delivered with 100% oxygen for 90 min at 2.0-2.4 ATA. Wound sizes were assessed by one wound surgeon before, during, and every 2 weeks for a total of 12 months after HBO. An analysis of demographic data, wound size and wound photography was performed. Over the 22-month period ending October 31, 2013, 40 patients (21 men and 19 women) with a mean age of 59.73 (range, 29-88) with complex wounds were included. All complex wounds studied were at least 6 months old. The mean wound size was 16.72 cm(2) in diameter. Thirty-one patients with complex wounds healed after the completion of a series of HBO treatments (77.5%). Two orocutaneous fistulas were completely closed without further surgery. After 5 HBO treatments, the wound size reduced by 29.7% on average (p = 1.24 × 10(-6)). After 10 HBO treatments, the wound size statistically significantly reduced by an additional 16.9% (p = 0.0002). There were no complications in this study. Wound healing process was accelerated by HBO. Significant wound size reduction was noted after 5 HBO treatments. Because the biggest reduction in wound size occurred within the first 10 HBO treatments, it is important to conduct these first treatments without interruption. HBO is an effective and safe treatment modality for complex wounds.

Cost-effectiveness analysis in comparing alginate silver dressing with silver zinc sulfadiazine cream in the treatment of pressure ulcers.

BACKGROUND: The treatment of pressure ulcers is complicated, given the various wound dressing products available. The cost of different treatments varies and the cost-effectiveness of each product has not been thoroughly evaluated. We compare two wound dressing protocols-alginate silver dressing (AlSD) and silver zinc sulfadiazine cream (AgZnSD) with regard to wound healing and cost-effectiveness. METHODS: Patients with grade III or IV sacral or trochanteric pressure ulcers were eligible for this prospective, randomized controlled trial. The patients were randomized to receive one of the two dressings for an eight-week period. The criteria of efficacy were based on the Pressure Ulcer Scale for Healing (PUSH) scoring tool. The cost of treatment was also assessed. RESULTS: Twenty patients (12 women and 8 men) were randomly assigned to receive either AlSD (n=10) or AgZnSD cream (n=10). The demographic data and wound characteristics were comparable in the two groups. The two groups showed no significant difference in the reduction of PUSH score, wound size, or volume of exudate. The tissue type score was significantly lower in the AlSD group (3.15±0.68-1.85±0.68 vs. 2.73±0.79-2.2±0.41; P=0.015). The cost of treatment was significantly lower in the AlSD group (377.17 vs. 467.74 USD, respectively; P<0.0001). CONCLUSIONS: Alginate silver dressing could be effectively used in the treatment of grade III and IV pressure ulcers. It can improve wound tissue characteristics and is cost-effective.

The efficacy of combined herbal extracts gel in reducing scar development at a split-thickness skin graft donor site.

BACKGROUND: The aim of this study was to evaluate the efficacy of combined herbal extracts in a gel preparation (Cybele(®) Scagel) in reducing scar development at a split-thickness skin graft donor site. METHODS: A prospective, randomized, double-blind control study was performed to evaluate the efficacy of Scagel in 15 patients who underwent a split-thickness skin graft operation. Both Scagel and placebo were applied equally to the donor site within 1 month after complete epithelialization. Scar assessments using the Vancouver Scar Scale (VSS) and patient self-evaluation were taken at 2, 4, 8, and 12 weeks. RESULTS: Of the 15 patients, 10 were enrolled and evaluated in this study. There was no significant difference in each parameter of the VSS. The total VSS was significantly lower in the Scagel group compared to the placebo group after 4 weeks (p = 0.003, 0.003, and <0.001 at 4, 8, and 12 weeks, respectively). The patient satisfaction score in the Cybele(®) Scagel group was significantly higher (p = 0.002) at the 12-week evaluation. CONCLUSION: Application of combined herbal extracts in gel preparation might reduce scar development at split-thickness skin graft donor sites. There was a positive trend in the reduction of postinflammatory hyperpigmentation. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Siliconoma of the breasts.

Despite prohibiting of the foreign material injection for aesthetic breast augmentation in many countries. Its late complications still bring patients back for corrective and reconstructive surgery. There is no clinical management consensus or international guideline. Most of the literatures recommend surgical removal with immediate reconstruction with autologous tissue. We report a case of bilateral breast siliconoma which was treated by total mastectomy with two stage tissue expander-prosthesis reconstruction.

Augmentation rhinoplasty with custom-made S-shape silicone implant in Asians: A 15-year experience.

BACKGROUND: Asians have low nasal dorsum, thick skin envelope, low defined alar cartilage, low projection of nasal tip and broad alar base. Augmentation rhinoplasty with silicone prosthesis has been performed with predictable results, but unfavourable results and complications still present. This series show techniques and results from single surgeon experience. MATERIALS AND METHODS: We retrospectively reviewed 548 patients chart during January 1995 to December 2009. All patients underwent custom-made S-shape implant silicone augmentation rhinoplasty operated by a single surgeon. There were three major operative steps: (1) Intra-operative S-shape implant carving; (2) pocket dissection through bilateral rim incision and (3) tension adjustment before closure. All the patients were recorded for early surgical complications and satisfaction. RESULTS: There were 519 women and 29 men. The mean age is 25.5 years (18-56 years). Mean follow-up period was 6 months (1-60 months). The majority of patient were appointed for esthetic augmentation (86.8%). 515 cases (94.9%) showed well satisfaction following the operation. The total complication rate was 6.5% (4.9% deviation, 0.7% extrusion, 0.5% hematoma and 0.3% infection). All the complications were corrected with uneventful sequelae. CONCLUSION: Augmentation rhinoplasty with custom-made S-shape silicone implant by closed approach provides high satisfaction with acceptable early complication rate.

The efficacy of silver mesh dressing compared with silver sulfadiazine cream for the treatment of pressure ulcers.

BACKGROUND: Controlling infection and promoting healing should be aims of pressure ulcer treatment along with improving a patient's general condition and relieving pressure. Many pressure ulcers present with cavities, tracks or a combination of these. A new silver mesh dressing (Tegaderm Ag Mesh dressing) has the ability to contour around and conform to irregular surfaces of a wound bed. OBJECTIVE: To evaluate the efficacy of a silver mesh dressing compared with silver sulfadiazine cream for pressure ulcer treatment. MATERIAL AND METHOD: A prospective, randomized, clinical trial was conducted in patients with pressure ulcers grade III or IV. The patients were divided randomly by computer into two 20 patient-groups. The study period was eight weeks for each patient. Demographic data, wound size, wound photography, and bacterial wound culture were recorded at the beginning of the study and every two weeks thereafter. Wound beds were covered with silver sulfadiazine cream in the control group and silver mesh dressing in the experimental group. Dressings were changed twice a day in the control group and every three days in the experimental group. RESULTS: Forty-five patients enrolled in the present study but only 40 patients finished the study. Twenty patients in each group finished the eight-week study. The mean healing rates and the percentage of reduction in PUSH score at eight-week were better in the study group than in the control group but they were not statistically significant. Better changing in bacteriological study after the treatment was shown in both groups. The estimated average cost of the treatment in the mesh group was 263 USD per patient while it was 1812 USD in the cream one (p = 0.0001). Silver mesh dressing can be adapted very well on the bed, can control infection, and promote wound healing. Wound reduction was greater in the experimental group than the control group. The cost of treatment, using silver mesh was cheaper than using silver sulfadiazine cream significantly. CONCLUSION: Silver mesh dressings is one of the choices for pressure ulcer treatment with good healing rate, minimal care and lower overall cost.

Comparison of the ionic silver-containing hydrofiber and paraffin gauze dressing on split-thickness skin graft donor sites.

The split-thickness skin graft (STSG) donor site dressing has been an inconclusive topic. Each of the Hydrofiber (Aquacel, ConvaTec A Bristol-Myers Squibb Company, Deeside, UK) and silver dressings have applied in many types of wound care with favorable outcomes. Our study compared the ionic silver-containing Hydrofiber dressing and paraffin gauze dressing. The subjects were randomized into group A: ionic silver-containing Hydrofiber and group B: paraffin gauze. From February 2006 to 2007, 20 donor sites were recorded. The mean donor site surface area was 145.5 cm2 (group A) and 135.8 cm2 (group B). The completed re-epithelization day was 7.90 and 11.20 days, respectively (P = 0.031). The average pain score at rest were 0.74 and 0.80, respectively (P = 0.894). The average pain score on dressing removal were 3.12 and 4.70, respectively (P = 0.027). There was no infection or seroma in both groups. In conclusion, ionic silver-containing Hydrofiber dressing can reduce STSG donor site pain and promote re-epithelization compared to paraffin gauze dressing.

The efficacy of 5% imiquimod cream in the prevention of recurrence of excised keloids.

OBJECTIVE: To evaluate the efficacy of 5% imiquimod cream in the prevention of recurrence of excised keloids. MATERIAL AND METHOD: The patients with keloids that had occurred over 1 year and could be excised and primary sutured were enrolled in the study. Imiquimod 5% cream was applied to the scar 7 days after stitches removal. The patients were follow-up for recurrence and drug side effect at 4, 6, 8, 16, and 24 weeks. RESULTS: Forty-five patients enrolled to the study but only 35 patients finished the study. The keloids were at the pinnas in 22 patients, at the backs or shoulders in 7 patients, and at chest walls or necks in 6 patients. Imiquimod 5% cream was applied on the wound area 2 weeks after the operation, at alternate night for 8 weeks. The follow-up period ranged from 6 to 9 months. Ten of the treated keloids recurred (28.6% recurrent rate). The lesion at the pinna had the lowest recurrent rate (2.9% recurrent of the total patients). The highest recurrent rate occurred at the chest wall or neck (83.3% recurrent of the chest wall or neck or 14.3% of the total patients). Side effects were found in thirteen patients (37.1%). These were abrasions of the skin around the wound areas in ten patients and hyperpigmentation of the skin around the wounds in three patients. CONCLUSION: Imiquimod 5% cream could effectively prevent recurrence of the excised keloids, especially in the area that had less tension such as pinna.

Short incisional double-eyelid blepharoplasty for Asian patients.

BACKGROUND: The author found that nonexcisional techniques commonly used to create a double eyelid in Asian patients did not create a natural-looking fold, while most transcutaneous double-lid procedures involved unnecessary excision of eyelid skin and orbicularis muscle, which could increase tension on the scar and make it more noticeable. OBJECTIVE: The author describes a technique for creation of a double eyelid, based in part on new anatomic findings, that uses a short incision to minimize the scar. METHODS: The thick orbital septum was opened, the supratarsal tendon was divided, the central fat compartment was removed, and the dermis was fixed to the tarsal plate. RESULTS: Between January 2000 and December 2004, 652 patients were operated using this technique. The mean age of the patients was 24 years. There were no serious complications. Four hundred twenty patients (64.4%) were followed up to 2 months, and 162 patients (24.8%) had 1-year follow-up. All had satisfactory results, except for 8 patients who underwent a second procedure to correct unequal folds 2 months postoperatively. Ten patients lost their supratarsal folds within 1 year postoperatively; all had satisfactory results after reoperation. CONCLUSIONS: The short incisional technique for creation of a double eyelid described here provides excellent results with no visible scar and no serious complications.
