Comparing between the effect of Fractional Microneedling Radiofrequency Versus Intralesional Steroid Injection with and without Microneedling on Tissue levels of PDGF & CTGF in Hypertrophic Scars
This study will evaluate the efficacy of pulsed dye laser (PDL) and carbon dioxide (CO2) laser in conjunction with usual care (MED) for the treatment of hypertrophic burn scars and will determine the optimal sequence and timing of lasers and usual care.
Skin injuries due to trauma are relatively common, and patients are very concerned about scars caused by trauma and primary repair. Recently, the use of ablative and non-ablative lasers based on the fractional approach has become a novel strategy for the treatment of scars. The objective of this study is to compare the efficacy of dual-mode Er:YAG laser delivering pulses either with and without heat/coagulation in a cohort of patients with long keloid/hypertrophic scars. The main hypothesis is that ablative fractional laser without heat/coagulation is equivalent to laser with heat/coagulation in terms of scars volume reduction, while the secondary hypothesis is that ablative fractional laser without heat/coagulation is superior in terms of post-operative erythema and hypopigmentation reduction.
The objective of this study is to evaluate the efficacy and safety of using ablative fractional laser- assisted topical corticosteroid delivery for the treatment of hypertrophic scar.
This project aims to understand the molecular biology underlying the improvement of surgical scars treated by ablative fractional photothermolysis (FP). Previous human studies at MGH have shown that FP significantly improves the appearance and functionality of surgical and burn scars. At the Wellman Center, we have conducted a randomized, controlled study on linear surgical scars demonstrating the efficacy of FP to decrease the volume of hypertrophic scars, and to improve the appearance and texture of scars. However, the underlying mechanism of this therapeutic effect is unknown. It is clear that FP induces wound healing and remodeling of the normal skin surrounding microthermal zones (MTZs). Furthermore, other researchers have employed animal models using transgenic zebrafish and the mouse eye, and found that laser treatments induce changes in gene expression in specific cells. We propose to determine whether the effect of FP on scar improvement occurs via changes in patterns of local gene expression within the skin, specifically dermal fibroblasts. By characterizing these changes, we may be able to identify molecular mechanisms that both explain and contribute to the beneficial effects of FP in the surgical and traumatic scar. The molecular insights into the therapeutic effects of fractional laser photothermolysis may provide a basis for future therapeutic strategies to improve scar remodeling.
Most children with cancer need a central venous catheter. These catheters are typically placed on the anterior thorax, where the risk of hypertrophic scarring and keloid development is greatly enhanced. A significant part of the children who have survived childhood cancer are troubled by their scars. Topical glucocorticoid treatment is known to induce a reduction of the collagen in the connective tissue. The investigators hypothesize that treatment with topical glucocorticoids for one week before and three weeks after removal of a central venous catheter, will reduce the formation of hypertrophic scarring and keloid development in children.
Keloids and hypertrophic scars are a common subject of dermatologic consultations. Therapeutic management of such conditions remains challenging because of their high rate of recurrence and lack of curative treatment.
The purpose of the study is to assess the efficacy of CICATRIX (Asian Gotu Kola or Pennywort) usage in the treatment of Hypertrophic scars and keloids. The duration of this double-blind placebo controlled phase 3 clinical trial will be 12 weeks. The estimated number of persons to be recruited and randomized for the study is 90.
Keloids and hypertrophic scars are not major illness. However, their effects can be from causing pain and itch which substantially interfere daily activity to as severe as causing deformity and other functional impairment. For standard surgical wounds, taking median sternotomy wounds from open heart surgery and lower abdominal wounds from gynecological wounds for example, the incidence of these problems can be from 10% to 60%. To prevent or treat these problems, physicians have used many modalities. One of the most convenient, most cost-effective and most non-invasive methods for patients is using dressings like silicone sheets, silicone gels or paper tapes, which is on the list of 1st line choices of an international recommendation. According to a literature review, most of the previous studies on similar topics are either of small sample size, on non-standard wounds or comparisons between wounds on different patient groups. The methodologies of previous studies are thus not vigorous enough. To get the highest level of evidence on selecting the best dressings for preventing and treating keloids and hypertrophic scars, we will recruit about 75 patients and apply two selected dressings on each halves of their standard surgical wounds to compare their differences. The investigators hope the result of this study can help us find the best modality to use and can contribute to the welfare of our future patients.
