Evaluating outcomes of pulsed dye laser therapy combined with intralesional triamcinolone injection after surgical removal of hypertrophic cesarean section scars.

BACKGROUND: Recently, pulsed dye laser (PDL) combined with triamcinolone intralesional injection (TAILI) has been introduced for surgical scar prevention. However, little is known about this procedure's effectiveness in preventing hypertrophic scar following surgical scar removal. OBJECTIVES: This study aimed to evaluate the outcome of early intervention using PDL combined with TAILI after surgical removal of hypertrophic cesarean section (CS) scars. METHODS: The medical records of 35 patients who underwent early intervention using PDL and TAILI after removal of hypertrophic CS scars were retrospectively reviewed. The scars' average Vancouver Scar Scale (VSS) scores before scar removal and 3 months after the final treatment were compared. RESULTS: The patients received 4.23 treatments on average and were followed up for a mean period of 7.74 months. The mean final VSS was 3.11 ± 1.52 and was significantly lower than that of the previous VSS (9.29 ± 1.74, p = 0.000). VSS of the previous CS scar, and the presence or absence of keloid formation in other areas, was associated with treatment outcome (p = 0.003 and 0.008, respectively). CONCLUSIONS: Early intervention using PDL combined with TAILI could prevent the recurrence or progression of hypertrophic CS scarring after surgical scar removal.

The Most Current Algorithms for the Treatment and Prevention of Hypertrophic Scars and Keloids: A 2020 Update of the Algorithms Published 10 Years Ago.

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.

Common Dermatologic Procedures and the Associated Complications Unique to Skin of Color.

BACKGROUND: The skin of color (SOC) population in the United States continues to grow, and these patients are undergoing various cosmetic and surgical procedures at increasing rates. There is a paucity of data on the potential complications associated with surgical and cosmetic procedures in this patient population. OBJECTIVE: We aim to educate dermatologic surgeons and clinicians on surgical and cosmetic procedures in patients of color and increase awareness of the potential complications unique to this patient population. MATERIALS AND METHODS: A thorough PubMed literature search was performed to conduct this review. RESULTS: There are a number of complications in SOC that require special attention, including keloids, postoperative infections, postinflammatory hyperpigmentation, and hypopigmentation. There are also various precautions to consider when performing cosmetic procedures, such as neurotoxin and filler injections, laser therapy, microneedling, and chemical peels. CONCLUSION: Dermatologists should be aware of the potential cosmetic and surgical complications of this growing patient population to provide optimal evidence-based medical care.

Are Prophylactic Measures Necessary to Prevent Recurrence of Penile Keloids?

Keloid scars result from excess collagen deposition in the dermis or subcutaneous tissue in response to surgery or tissue trauma. The penis is a rare site for keloid formation, even in predisposed individuals. Only few cases of penile keloids have been reported so far. In this report, we present penile keloids complicating neonatal circumcision in twin brothers. Risk of recurrence in previous reports and measures to guard against its occurrence are also discussed.

Centella asiatica (Centellicum®) facilitates the regular healing of surgical scars in subjects at high risk of keloids.

BACKGROUND: Formation of scars after surgical incisions requires the proper appositions of elements contributing to the scarring process. The structural rebuilding of damaged tissues is essential in producing a linear scar. The excess of blood, foreign particles, exuberant sutures, necrotic tissue, possible infective agents, as well as the ongoing inflammatory process may produce a non-linear, sometimes painful keloidal scar. Centella asiatica (CA) extracts have been used topically since ancient times for preventing keloids (i.e. after extensive burns) and for other applications including ulcer healing. The aim of this registry study was to evaluate the effect of supplementation with Centellicum® (Horphag Research Ltd.) on the healing of surgical wounds in subjects with previous hypertrophic or keloid scars, and to identify with ultrasound the collagen components of the scar in order to assess the quality (or linearity) of surgical wounds. METHODS: Subjects with history of hypertrophic scars or keloid following previous surgery were included in this registry. Short term antibiotic prophylaxis was used as per surgical standards with cephalosporins for three days maximum after surgery. Only patients receiving abdominal or knee surgery were included. A total of 129 patients were included: 64 in the control group treated only with standard management, and 65 in the active treatment group where CA supplementation with Centellicum® was used at the dose of two 225 mg capsules/day from the 2nd to 6th week after surgery. RESULTS: A total of 64 scars were analyzed within the control group and 65 in the supplement group. The tolerability to Centellicum® was overall good, and no side effects were reported. Compliance to treatment was optimal, with >98% of the CA capsules correctly used. The ultrasound-assessed scar tissue regularity was on average lower in controls than in supplemented subjects (P<0.05). Scars also appeared to be significantly more homogeneous in CA patients than in controls. CONCLUSIONS: Supplementation with Centellicum® is safe and does not interfere with other concomitant treatments. It is well tolerated and compliance to treatment is optimal.

Perception of Community and Hospital Personnel on Burn Treatment and Outcome in Nepal.

INTRODUCTION: Globally, eleven million people sustain burn injuries every year enough to require medical attention. WHO has estimated Disability associated limited years of 84,000 per year just due to deformities and 2100 people die every year due to burn injuries in Nepal. The overall objective of the study is to explore the effectiveness of burn injuries treatment and management approach of hospitals. METHODS: This qualitative study approached to 40 Health Personnel for Key Informants Interviews and 18 Focus Group Discussions with community people at the ten referral hospitals of eight district from May-June 2016. Qualitative data were analyzed using AtLas.ti software. RESULTS: Female burn victims are brought late to the hospital compared to male patients and false reporting about incident is usually done by her attendants. More than three-fourth (80%) of the hospitals and about one-third male and female from FGD reported that the community people seek home remedy first rather than medical treatment. Majority of the medical doctors and nursing chiefs reported that first degree cases accounts for 50% of the total burn cases with a success rate of 80%. Medical and Nursing staff reported that deformities like hypertrophic scar, keloids, joint stiffness and compartment syndrome are mostly observed during the treatment. Hypothermia and sepsis were the major causes of death in most of the burn patients. CONCLUSIONS: Usually, people who engaged in house and agriculture works, have visited public health posts/hospitals more frequently due to financial constraints and transportation issues where quality of burn care services are unavailable.

Keloids and Hypertrophic Scars: A Spectrum of Clinical Challenges.

Since their earliest description, keloids and hypertrophic scars have beleaguered patients and clinicians alike. These scars can be aesthetically disfiguring, functionally debilitating, emotionally distressing, and psychologically damaging, culminating in a significant burden for patients. Our current understanding of keloid pathophysiology has grown and continues to advance while molecular biology, genetics, and technology provide ever-deepening insight into the nature of wound healing and the pathologic perturbations thereof. Greater understanding will lead to the development and application of refined therapeutic modalities. This article provides an overview of our current understanding of keloids, highlighting clinical characteristics and diagnostic criteria while providing a comprehensive summary of the many therapeutic modalities available. The proposed mechanism, application, adverse events, and reported efficacy of each modality is evaluated, and current recommendations are summarized.

Flash-lamp pulsed-dye laser treatment of keloids: results of an observational study.

OBJECTIVE: Flash lamp pulsed dye laser (FPDL) was used in a selected group of patients with hypertrophic scars and keloids. Objective of the study was to assess the efficacy on a large number of cases. BACKGROUND DATA: FPDL is a nonablative technology, typically used in vascular malformation therapy because of its specificity for hemoglobin. METHODS: A total of 59 patients (33 males and 26 females, mean age 37.5 years) affected by hypertrophic postsurgical scars and keloids, underwent from four to six treatment sessions with a flash lamp pumped pulsed dye laser. Clinical follow-up was performed 6 months after the last treatment. Results were judged by blind observers. RESULTS: A total of 29 patients out of 59 (49.1%) achieved excellent clearance, 15 patients (25.4%) achieved good to moderate clearance, and 12 patients (20.4%) obtained slight improvement. Only three subjects (5%) had little or no removal of their lesion. Treatment was well tolerated with minor and transient side effects. CONCLUSIONS: FPDL is known as a safe and effective treatment for different dermatological lesions in which skin microvessels play a key role in pathogenesis or development. This laser was effective when applied to hypertrophic scars and keloids. Further studies in a larger set of patients, however, are required to assess a standardized and reproducible method for treating these lesions.

Are there any good treatments for keloid scarring after sternotomy?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: in patients with hypertrophic and keloid scarring of the sternotomy wound, is surgical excision with or without adjuvant treatment of any benefit in reducing the size of the scar? Altogether, more than 15 papers were found using the reported search, of which nine represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. One of the studies showed no difference between surgery and adjunctive triamcinolone or colchicine. One study showed that incomplete excision resulted in higher recurrence rates. Postoperative radiation was found to be useful in two of the studies, although one study showed that it was not useful. One randomized control trial showed improvement after laser compared to no treatment. Two other trials showed no difference between laser, silicone gel, intralesional steroid or 5-fluorouracil. One trial showed that perioperative systemic steroid application gave rise to no improvement but in fact worsened scar formation. We conclude that small keloids can be treated radically by surgery with adjuvant therapy (radiation or corticosteroid injections) or by non-surgical therapy (corticosteroid injections, laser and anti-tumour/immunosuppressive agents, such as 5-fluorouracil). Large and multiple keloids are difficult to treat radically and are currently only treatable by multimodal therapies that aim to relieve symptoms.

Cosmetic procedures in skin of color.

An increasing proportion of patients undergoing aesthetic procedures are individuals with skin of color (Fitzpatrick skin types IV-VI). Racial or ethnic differences exist in perceptions of beauty, the prevalence of specific cosmetic concerns, as well as optimal approaches to treatment. Most important, is the need to avoid treatment-associated pigmentary alterations and keloid scarring, of which there is a greater risk in patients with skin of color. Here we review leading esthetic concerns in the darker skinned patient and discuss approaches to treatment.

[Pseudofolliculitis barbae]. / Pseudofoliculitis de la barba.

Pseudofolliculitis barbae is a chronic, irritating, and potentially disfiguring condition that develops as a result of attempts to eliminate hair from the beard area, usually by shaving. It is difficult to determine the incidence of the disorder, but some studies report that it affects up to 1 of every 5 caucasian individuals and that it is much more common in black persons. Clinically it is characterized by the appearance of inflammatory papules and pustules. Once pseudofolliculitis has become established, treatment consists of avoiding shaving and the use of medical treatment similar to that used in acne. However, the long-term result is much more dependent on prevention through a correct shaving technique. In severe cases or when a definitive solution is sought, the treatment of choice is photodepilation.

Dermatitis artefacta: keloids and foreign body granuloma due to overvalued ideation of acupuncture.

Skin is well recognized as an important somatic mirror of one's emotion and a site for the discharge of one's anxieties. We present a case of a 42-year-old female patient presenting with a vague history of generalized body pain and skin lesions in the form of cotton threads buried under the skin, crusted plaque, multiple keloids and rusted pin buried through the skin mostly in the easily accessible areas of the body. Histopathology from the crusted plaque revealed foreign body granuloma. To satisfy her psychological or emotional need, it is the deliberate and conscious production of self-inflicted skin lesions through overvalued ideation of acupuncture on her part.

Do postsurgical interventions optimize ultimate scar cosmesis.

Keloids and other scars are different manifestations of the normal wound healing process. If located in visible areas, scars may have a psychological impact that could affect the quality of life of the scar-bearing population. Good preoperatory planning including hiding incisions in natural anatomical landmarks or placing them parallel to relaxed skin tension lines are among the techniques used to improve the cosmesis of scars. Once a prominent or noticeable scar has developed, multiple therapeutic modalities can be applied including surgical excision, although high recurrence rates precludes its use as monotherapy. Several advanced surgical correction techniques including Z-plasty and W-plasty may be useful in repositioning scars. Other modalities that have been reported to improve scar cosmesis include cryosurgery, radiotherapy, lasers, and skin substitute grafts. Adjuvant postsurgical treatment modalities have reduced dramatically the recurrence rates associated with the removal of the scar. In this review of the literature the authors discuss evidence based data related to the abovementioned modalities and other topical and intralesional therapies including occlusion, compression, silicone, corticosteroids, interferons, imiquimod, resiquimod, tacrolimus, 5-fluorouracil, retinoids, as well as the role of several over-the-counter agents such as onion extract, vitamin E and the combination of hydrocortisone, vitamin E and silicone. Finally, they address newer modalities including vascular endothelial growth factor inhibitor, transforming growth factor-3, interleukin-10, mannose-6-phosphate, UVA-1, narrowband UVB, intense pulsed light and photodynamic therapy. Ultimately, the decision of choosing the most appropriate postexcisional management treatment should be taken by physicians on a case-by-case basis in order to obtain the best cosmetically acceptable results.

Cepan Cream has been applied in therapeutics for 20 years. This drug is used for topical treatment of burn scars and keloids as well as post-operative scars and contractures. Cepan produces a multidirectional effect. Cepan is well tolerated. Pharmacological property analysis of active ingredients, results of physical, biochemical studies and clinical estimation indicate that the evaluated preparation is both effective and safe. Lately, new information on Cepan effectiveness in eyelids inflammation caused by parasite Demodex folliculorum has been particulary interesting.

Prevention and management of hypertrophic scars and keloids after burns in children.

Hypertrophic scars and keloids are challenging to manage, particularly as sequelae of burns in children in whom the psychologic burden and skin characteristics differ substantially from adults. Prevention of hypertrophic scars and keloids after burns is currently the best strategy in their management to avoid permanent functional and aesthetical alterations. Several actions can be taken to prevent their occurrence, including parental and children education regarding handling sources of fire and flammable materials, among others. Combination of therapies is the mainstay of current burn scar management, including surgical reconstruction, pressure therapy, silicon gels and sheets, and temporary garments. Other adjuvant therapies such as topical imiquimod, tacrolimus, and retinoids, as well as intralesional corticosteroids, 5-fluorouracil, interferons, and bleomycin, have been used with relative success. Cryosurgery and lasers have also been reported as alternatives. Newer treatments aimed at molecular targets such as cytokines, growth factors, and gene therapy, currently in developing stages, are considered the future of the treatment of postburn hypertrophic scars and keloids in children.
