Filter by:Purpose of the study: The purpose of the study is to evaluate the therapeutic effect of cryotherpy in treating hypertrophic scar. It will be hypothesized that: Cryotherapy may not have an effect on hypertrophic scar.
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
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 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.
