Effect of the combination of photobiomodulation therapy and the intralesional administration of corticoid in the preoperative and postoperative periods of keloid surgery: A randomized, controlled, double-blind trial protocol study.

Keloid scars are characterized by the excessive proliferation of fibroblasts and an imbalance between the production and degradation of collagen, leading to its buildup in the dermis. There is no "gold standard" treatment for this condition, and the recurrence is frequent after surgical procedures removal. In vitro studies have demonstrated that photobiomodulation (PBM) using the blue wavelength reduces the proliferation speed and the number of fibroblasts as well as the expression of TGF-ß. There are no protocols studied and established for the treatment of keloids with blue LED. Therefore, the purpose of this study is to determine the effects of the combination of PBM with blue light and the intralesional administration of the corticoid triamcinolone hexacetonide on the quality of the remaining scar by Vancouver Scar Scale in the postoperative period of keloid surgery. A randomized, controlled, double-blind, clinical trial will be conducted involving two groups: 1) Sham (n = 29): intralesional administration of corticoid (IAC) and sham PBM in the preoperative and postoperative periods of keloid removal surgery; and 2) active PBM combined with IAC (n = 29) in the preoperative and postoperative periods of keloid removal surgery. Transcutaneous PBM will be performed on the keloid region in the preoperative period and on the remaining scar in the postoperative period using blue LED (470 nm, 400 mW, 4J per point on 10 linear points). The patients will answer two questionnaires: one for the assessment of quality of life (Qualifibro-UNIFESP) and one for the assessment of satisfaction with the scar (PSAQ). The team of five plastic surgeons will answer the Vancouver Scar Scale (VSS). All questionnaires will be administered one, three, six, and twelve months postoperatively. The keloids will be molded in silicone prior to the onset of treatment and prior to excision to assess pre-treatment and post-treatment size. The same will be performed for the remaining scar at one, three, six, and twelve months postoperatively. The removed keloid will be submitted to histopathological analysis for the determination of the quantity of fibroblasts, the organization and distribution of collagen (picrosirius staining), and the genic expression of TGF-ß (qPCR). All data will be submitted to statistical analysis. Trial registration: This study is registered in ClinicalTrials.gov (ID: NCT04824612).

Novel targets and therapies for keloid.

Keloids are the result of aberrant tissue scarring typically occurring in injured skin, and are caused by the overgrowth of granulation tissue or collagen type III during the healing process. There is a genetic component, thus a predisposition can be genetically transmitted. Keloids are difficult to treat because of their postexcisional recurrence, and they have an impact on patient quality of life due to psychological distress caused by cosmetic concerns and functional disability. Treatment ranges from classic corticosteroid therapy to multimodal approaches such as injections, cryotherapy, laser, radiation, radiofrequency ablation and extracorporeal shockwave therapy. Recent discoveries into the pathogenesis of keloid have enabled clinicians to expand the therapeutic options for treatment. The aim of this paper was to review the literature, clarify the general concept of keloid development, and assess emerging treatment options such as stem cell therapy, mitomycin C, bleomycin, interferon, botulinum toxin type A, calcium channel blockers, angiotensin-converting enzyme inhibitors and fat grafting, and the evolutionary advancement towards epigenetic modifications and gene therapy.

Keloid negatively affects body image.

BACKGROUND/OBJECTIVES: Keloid is a healing disorder that occurs exclusively in humans. This pathology is considered a benign cicatricial neoplasm, whose physiopathogenesis has not yet completely clarified. Its disfiguring appearance often could potentially cause a disturbance in the patient regarding his/her body image. The objective is to evaluate the impact of keloid on body image. METHODS: 61 patients with keloid in socially exposed regions of the body were included. The participants were submitted to clinical evaluation, composed of anamnesis and physical examination, and answered two questionnaires: the Body Dysmorphic Symptoms Scale (BDSS) questionnaire and the Rosenberg Self-Esteem Scale - Unifesp/EPM. RESULTS: Forty percent of the patients had negative aspects of body image (BDSS score≥6). The scores of these patients on the Rosenberg Scale reached an average of 10.5 (p<0.03). CONCLUSIONS: The presence of a keloid negatively affects body image.

The lived experience and quality of life with burn scarring-The results from a large-scale online survey.

A large-scale online survey was designed to both inform and direct the development of an online community healthcare hub for people living with scarring. Focussed areas of questioning were generated to gather information on psychological symptoms, scar support and knowledge of wounds and healing. Simple statistical data was produced on the severity, aetiology and location of scarring. A secondary data analysis of the survey responses was conducted on more focussed themes. This survey was completed by 1034 people living with scars, 119 of which had burn scarring. The results highlight that patients with burn scars have higher levels of pre-existing psychological difficulties, carry a greater number of scars and experience more symptoms. A lack of support is identified for patients with scars once they have been discharged by their healthcare provider. The most popular forms of support were chosen as face-to-face interaction or online support. Key areas of support were found to be psychology particularly for help with acceptance or coping methods, wound care advice and meeting with other patients with scars. For these patients, key themes in the psychological impact of scarring include appearance-related concerns, social anxiety, acceptance and coping, experience of symptoms, skin viability and survivorship.

Burden of Keloid Disease: A Cross-sectional Health-related Quality of Life Assessment.

Keloid scars may be painful, itch severely and be cosmetically disturbing. The burden of keloid disease, however, has not yet been determined. This study evaluated the association of keloid disease with health-related quality of life (HRQL) and identified indicators of burden using a cross-sectional survey study, with one disease-specific HRQL measure (Skindex-29) and 2 generic HRQL measures (SF-36 and EQ-5D-5L). A total of 106 keloid patients with no other skin diseases participated in the study. Having keloid disease was associated with a considerable impairment of emotional wellbeing, with most impairment on the emotional and mental HRQL. Pain and itch were the strongest indicators of HRQL impairment in keloid patients. Having painful or itchy keloids was related to low mental and emotional HRQL, implying that patients with keloids require access to effective treatment aimed at alleviating physical symptoms.

Creation of a head and neck Keloid quality of life questionnaire.

OBJECTIVES: Create a head-and-neck keloid quality of life (QOL) questionnaire. Demonstrate the reliability of the keloid-specific QOL scale according to test-retest and internal consistency standards. STUDY DESIGN: Prospective cohort study. METHODS: Patients presenting to a keloid clinic in a tertiary referral institution between April 2012 and February 2013 were enrolled on their first visit. They were administered a questionnaire assessing demographics and a 21-item Likert keloid-specific survey assessing symptomatology, self-esteem, social functioning, and therapeutic motivation during their first three visits. Reliability of the keloid questionnaire was assessed for internal consistency (Cronbach's alpha) and test-retest correlations. Patients were treated with Kenalog steroid injections at each visit. The 126-point total score from the questionnaire was then compared to each subscale (physical symptoms, self-esteem, social function, and medical motivation) using a Pearson coefficient. RESULTS: The keloid QOL questionnaire showed a Cronbach's alpha of 0.87 for the overall questionnaire and ranged from 0.66 to 0.86 for individual questions. The test-retest Pearson's R was 0.70 between visits 1 and 2 and 0.77 between visits 2 and 3. The Pearson correlation between symptoms, self-esteem, social functioning, and medical motivation subscales and the overall scale were 0.77, 0.73, 0.72, and 0.57, respectively. CONCLUSION: This head and neck keloid-specific QOL questionnaire proved to be a reproducible method of reliably assessing QOL burden on patients with head and neck keloids. LEVEL OF EVIDENCE: N/A.

The dermatology life quality index as a means to assess life quality in patients with different scar types.

BACKGROUND: Measuring quality of life through questionnaires is a common method to evaluate the impact of different afflictions on the patient's well-being, especially in the field of dermatology where appearance changing afflictions are common. OBJECTIVES: A variety of questionnaires has been used to distinguish different skin conditions like psoriasis, atopic dermatitis and scars. Using the Dermatology Life Quality Index (DLQI), we investigated different scar types regarding their impact on quality of life. METHODS: We assessed the quality of life in 130 patients presenting to our outpatient scar clinic for the first time using the DLQI. Scars were analysed according to their clinical appearance (physiological scars, keloids, hypertrophic scars, atrophic scars, self-harm scars). Physiological scars were established as a baseline for further comparison between groups. RESULTS: Patients in the physiological scar group scored a mean DLQI score of 2.07 ± 3.56, patients in the keloid-, hypertrophic scar-, atrophic scar- and self-harm scar group scored values of 6.06 ± 4.00, 2.53 ± 2.48, 7.26 ± 6.72 and 12.00 ± 3.85 respectively. When compared to the baseline group the difference in the overall score for keloids was +3.99 (P < 0.001), hypertrophic scars scored +0.45 (ns), atrophic scars +5.19 (P < 0.01) and self-harm scars +9.93 (P < 0.001). CONCLUSION: Using the DLQI, we could demonstrate that different subsets of pathological scars do affect patients in a different magnitude. The DLQI provides a promising adjunct for quantifying the quality of life in patients suffering from keloids, atrophic- and self-harm scars and may constitute an interesting additional tool for monitoring the progress of scar treatments.

Scars can be functionally or socially disabling. Many patients affected therefore request corrective surgery. The list of surgical techniques is long and the most frequently-used solutions are well-known.

Psychological stress as a risk factor for postoperative keloid recurrence.

OBJECTIVE: To investigate psychological stress on the prognosis of the postoperative recurrence of keloids. METHODS: Patients with keloids (n=25), candidates for surgical resection and postoperative radiotherapy, had their psychological stress evaluated on the day before the surgical procedure. The parameters evaluated were pain and itching (Visual Numerical Scale), quality of life (Questionnaire QualiFibro/Cirurgia Plástica-UNIFESP), perceived stress (Perceived Stress Scale), depression and anxiety (Hospital Depression and Anxiety Scale), salivary cortisol and minimum and maximum galvanic skin responses (GSR) at rest and under stress (i.e., while the questionnaires were being filled out). Patients were evaluated during the 3rd, 6th, 9th and 12th months of postoperative care. During each return visit, two experts classified the lesions as non-recurrent and recurrent. RESULTS: The recurrence group presented the greatest values in GSR during a stressful situation. The chance of recurrence increased by 34% at each increase of 1000 arbitrary units in maximum GSR during stress. CONCLUSION: Psychological stress influenced the recurrence of keloids.

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.

Keloids: assessment of effects and psychosocial-impacts on subjects in a black African population.

BACKGROUND: Keloids are vexatious swelling on the skin or the conjuctiva. The effects and impacts of these lesions have not been assessed in a keloid endemic environment like Nigeria. AIMS: The purpose of this study is to assess the psychosocial impact as well as effects of keloids on the subjects in a black African population where lesions are commonly seen. METHODS: This is a prospective study which assesses the impacts of keloid on keloid patients. Consented patients who presented to the Plastic Surgery Clinic of the Lautech Teaching Hospital, Osogbo, Nigeria were recruited into the study. A set of questionnaires were administered to all consented patients. The administered questionnaires were analyzed using SPSS version 10. RESULTS: One hundred and thirty one patients were involved in this study. They comprised of 61 males and 70 females. Most (96.8%) of them had the keloid lesion for more than one year. Sixteen (12.2%) of the patients felt that keloids negatively affect their works, 64 (48.9%) of the patients felt stigmatized by keloids, 28 (56.0%) of them who had lesions in conspicuous parts while 24 (46.2%) had lesions in non-conspicuous parts. Females (59.1%) felt stigmatized than males. Only 47 (35.8%) of the patients believed that keloid swelling limit their social interaction. CONCLUSION: Keloids do not appear to have significant negative impacts on keloid patients in a keloid-endemic community like a black African population.

What factors affect the quality of life of patients with keloids?

OBJECTIVE: To evaluate factors that affect the quality of life (QoL) of patients with keloids. METHODS: A study was conducted on 102 patients of both genders between 15 and 70 years old. During initial evaluation, clinical factors, such as keloid visibility, duration and evolution of the disease, previous treatments, types of treatments and recurrence were recorded. Later, patients responded to the QualiFibro questionnaire, which is specific for evaluation of the QoL of patients with keloids and comprises the physical and psychological domains, and six visual numeric scales (VNS), of which three are related to psychological factors (satisfaction with appearance, shame of the disease, and suffering experienced), and the other three are related to physical factors (pruritus, pain and movement restriction). RESULTS: Patients with keloids on non-visible areas of the body (p<0.01) and more than 10 years of disease (p<0.049) reported higher scores on the physical domain of the QualiFibro questionnaire, indicating increased severity compared with patients with keloids on visible areas of the body and disease duration of less than 10 years. There was a positive correlation between psychological (satisfaction with appearance, feelings of embarrassment about the disease and suffering experienced) and physical factors (pruritus, pain and movement restriction) evaluated using the VNSs, and both domains of the QualiFibro questionnaire. CONCLUSION: Results indicate that the physical domain of the QualiFibro questionnaire was the most affected in patients with keloids on non-visible areas and in those with keloids for more than 10 years. Psychological and physical factors associated with keloids as assessed with the VNS affected both psychological and physical domains of QoL.

OBJETIVO: Avaliar quais fatores influenciam a qualidade da vida (QV) dos portadores de quelóide. MÉTODOS: Estudo envolvendo 102 pacientes, de ambos os gêneros, com idade entre 15 e 70 anos. Na avaliação inicial, os fatores clínicos referentes à visibilidade do queloide, tempo de evolução da doença, tratamento prévio, tipos de tratamento e recidiva foram catalogados. Posteriormente, os pacientes responderam ao questionário QualiFibro, composto pelos domínios físico e psicológico, específico para avaliar a QV dos portadores de quelóide, e a seis escalas visuais numéricas (EVN), sendo três escalas em relação a fatores psicológico (satisfação com a aparência, vergonha da doença e sofrimento vivenciado), e três escalas em relação a fatores físicos (prurido, dor e restrição de movimentos). RESULTADOS: A pontuação do domínio físico do questionário QualiFibro foi maior para os portadores de queloide em região não-visível (p<0,01) e com tempo de evolução maior que 10 anos (p<0,049), refletindo piora em relação aos portadores com queloide em região visível e com tempo de evolução de doença menor que 10 anos. Houve correlação positiva entre os fatores psicológico (satisfação com a aparência, vergonha da doença e sofrimento vivenciado) e físicos (prurido, dor e restrição de movimentos) avaliados pelas EVN's e ambos os domínios do questionário QualiFibro (p<0,01). CONCLUSÃO: O domínio físico do questionário QualiFibro foi pior nos portadores de quelóide não-visível e naqueles com duração maior que 10 anos. Os fatores psicológicos e físicos das EVN's, implicados ao queloide, afetaram tanto o domínio físico quanto o domínio psicológico da QV.

Combination of surgery and intralesional verapamil injection in the treatment of the keloid.

Keloid scars are one of the most challenging problems for physicians and surgeons. These scars have been treated in many ways, with varying success. Verapamil is a widely used calcium channel antagonist, and it has been shown that calcium channel blockers inhibit the synthesis/secretion of extracellular matrix molecules, including collagen, glycosaminoglycans, and fibronectin, and increase collagenase. In this study, we performed total keloid excision in combination with reconstruction with W-plasty or skin grafting and injection of verapamil hydrochloride into the lesions of 21 patients with keloids. Patients were followed for minimum of 2 years, and the treatment outcome was evaluated based on the cosmetic appearances, symptomatic improvements, and the results of microscopic examinations. Also, patient satisfaction was scored with a visual analog scale. Two years after the operations, two patients had keloid in lesser diameter than the original lesions, two patients had lesions that were hypertrophic scars in appearance, and four patients had pruritus. One patient had keloid on the donor site. The rate of patient satisfaction was 6.4 on a scale of 1 to 10. We reviewed the treatment of keloid in this study and obtained one of the lower rates of complication in the literature. We believe that surgical excision with W-plasty or skin grafting and intralesional verapamil injection may be a good alternative in the treatment of keloid.
