RESUMO
BACKGROUND: In 2010, this Journal published my comprehensive review of the literature on hypertrophic scars and keloids. In that article, I presented evidence-based algorithms for the prevention and treatment of these refractory pathologic scars. In the ensuing decade, substantial progress has been made in the field, including many new randomized controlled trials. To reflect this, I have updated my review. METHODS: All studies were evaluated for methodologic quality. Baseline characteristics of patients were extracted along with the interventions and their outcomes. Systematic reviews, meta-analyses, and comprehensive reviews were included if available. RESULTS: Risk factors that promote hypertrophic scar and keloid growth include local factors (tension on the wound/scar), systemic factors (e.g., hypertension), genetic factors (e.g., single-nucleotide polymorphisms), and lifestyle factors. Treatment of hypertrophic scars depends on scar contracture severity: if severe, surgery is the first choice. If not, conservative therapies are indicated. Keloid treatment depends on whether they are small and single or large and multiple. Small and single keloids can be treated radically by surgery with adjuvant therapy (e.g., radiotherapy) or multimodal conservative therapy. For large and multiple keloids, volume- and number-reducing surgery is a choice. Regardless of the treatment(s), patients should be followed up over the long term. Conservative therapies, including gel sheets, tape fixation, topical and injected external agents, oral agents, and makeup therapy, should be administered on a case-by-case basis. CONCLUSIONS: Randomized controlled trials on pathologic scar management have increased markedly over the past decade. Although these studies suffer from various limitations, they have greatly improved hypertrophic scar and keloid management. Future high-quality trials are likely to improve the current hypertrophic scar and keloid treatment algorithms further.

Topical corticosteroid delivery following fractional laser treatment is an effective means of treating hypertrophic scars. However, the relative efficacy of adjuvant corticosteroid treatment vs fractional laser mono-therapy alone is unclear. The aim of this study was to compare the efficacy and safety of fractional laser-assisted topical corticosteroid delivery with fractional laser monotherapy in the treatment of hyper-trophic scars. In this randomized, comparative, split-scar trial of 19 subjects, a borderline significant reduction in scar thickness was observed at 3-month follow-up in the laser+steroid group compared with laser+petrolatum (p = 0.049). However, no significant long-term difference in scar flattening was observed between the 2 groups. Patient and Observer Scar Assessment Scale scores showed significant improvement in scar appearance from baseline without significant differences between treatment groups. In conclusion, fractional laser monotherapy is an effective treatment for hypertrophic scars, and the application of topical corticosteroid provides no long-term synergistic effect to fractional laser monotherapy.

INTRODUCTION: Hypertrophic scars are a common disease in plastic surgery, which is the reaction of skin connective tissue to trauma beyond the normal range. Although scholars around the world have explored the tissue structure and formation mechanism of HS for decades, they are not satisfactory the result of. No effective treatment has been found. Therefore, the search for safe and effective treatments for HS has always been the focus of medical attention and research. Acupuncture therapy has a definite effect on HS and has unique advantages. METHODS/DESIGN: In this study, we will use our own front-to-back clinical research method. We plan to include 120 young and middle-aged female patients who meet the diagnostic criteria for HS. The untreated HS of the enrolled patients will be used as blank controls. The intervention group will be given acupuncture treatment. The assessment of scar area, color, hardness, thickness, itching and pain will be recorded for 30 days of treatment. DISCUSSION: This trial may provide evidence regarding the clinical effectiveness, safety, and cost-effectiveness of Acupuncture for patients with HS. TRIAL REGISTRATION: ClinicalTrials.gov, ChiCTR2000032624, Registered on 04 May 2020.

The aim of the study was to evaluate the effectiveness of compression therapy with a prolonged plaster of Contractubex in the formation of skin scarring in children after surgery. MATERIAL AND METHODS: In a prospective open-label randomized trial, 109 patients aged 5.3±2.1 years after surgery: boys - 73, girls - 36. Patients were divided into 2 groups: in the main group (54 children) the application of the prolonged plaster Contractubex was performed; in the control group (55 patients) - dynamic observation. The scar deformation was assessed according to the Vancouver scale for 10, 30 and 90 postoperative days. RESULTS: 94.4% patients had good compliance; in 2 (3.7%) - satisfactory; in 1 (1.9%) - unsatisfactory compliance. In our study, the formation of hypertrophic scars in the main group was significantly less frequent than in the control group (1 and 8 patients, respectively, χ2=4.241, p=0.042). CONCLUSION: Thus, the use of the prolonged plaster Contractubex in the near and distant period a good cosmetic and functional result in the formation of a postoperative scar was provided.

Scars with flexion contracture of various origins are challenging problems which may cause not only cosmetic concerns, but also severe functional restriction. In this report, we describe a case presenting scars with flexion contracture: a 23-year-old Korean female with surgical scars on both axillae, which were treated by laser-cision (incision using carbon dioxide laser) with second intention wound healing followed by a non-ablative fractional photothermolysis system.

Many techniques for management of hypertrophic scars and keloids have been proven through extensive use, but few have been supported by prospective studies with adequate control groups. Several new therapies showed good results in small-scale trials, but these have not been repeated in larger trials with long-term follow-up. This article reports a qualitative overview of the available clinical literature by an international panel of experts using standard methods of appraisal. The article provides evidence- based recommendations on prevention and treatment of abnormal scarring and, where studies are insufficient, consensus on best practice. The recommendations focus on the management of hypertrophic scars and keloids, and are internationally applicable in a range of clinical situations. These recommendations support a move to a more evidence-based approach in scar management. This approach highlights a primary role for silicon gel sheeting and intralesional corticosteroids in the management of a wide variety of abnormal scars. The authors concluded that these are the only treatments for which sufficient evidence exists to make evidence-based recommendations. A number of other therapies that are in common use have achieved acceptance by the authors as standard practice. However, it is highly desirable that many standard practice and new emerging therapies undergo large-scale studies with long-term follow-up before being recommended conclusively as alternative therapies for scar management.
