Which Moisturizer to Use in Scar Therapy after Burn Injuries? A Subjective and Objective Skin and Scar Evaluation after Topical Treatment with Dexpanthenol, Aloe Vera, and Plant Oil.

Background and Objectives: Good scar management in burn care is essential. Nevertheless, there are no consistent recommendations regarding moisturizers for scar management. Our aim was to investigate and compare the effects of commonly used products on normal skin and burn scars. Materials and Methods: A total of 30 skin-healthy (control group) and 12 patients with burn scars were included in this study. For an intraindividual comparison, each participant received creams consisting of dexpanthenol (P), aloe vera (A), and a natural plant oil (O) with instructions to apply them daily to a previously defined area for at least 28 days. Objective scar evaluation was performed with Visioscan®; Tewameter®; Cutometer®, and the Oxygen To See® device. Subjective evaluation was performed with an "application" questionnaire, the Patient and Observer Scar Assessment Scale (POSAS), and with the "best of three" questionnaire. Results: After (A) a high trend of amelioration of +30%, TEWL was detected on the scar area. Blood flow increased slightly on healthy skin areas after (A) application to +104%. The application of (A) on healthy skin demonstrated a positive effect on the parameters of scaliness (+22%, p < 0.001), softness (+14%, p = 0.046), roughness R1 (+16%, p < 0.001) and R2 (+17%, p = 0.000), volume (+22%, p < 0.001), and surface area (+7%, p < 0.001) within the control group. After (P), a significant improvement of the baseline firmness parameter of +14.7% was detected (p = 0.007). (P) also showed a beneficial effect on the parameters of R1 (+7%, p = 0.003), R2 (+6%, p = 0.001), and volume (+17%, p = 0.001). (O) lead to a statistically significant improvement of volume (+15%, p = 0.009). Overall, most study participants stated (A) to be the "best of three". Conclusions: (A) performed statistically best, and is a well-tolerated moisturizing product. However, further quantitative studies are needed to provide statistically significant clarification for uniform recommendations for scar therapy.

Case Report in Equine: Highlighting the Benefits of Medisca CopaSil in Burn Scar Management.

In this case report, we highlight the benefits of Medisca CopaSil application for scar healing in a horse having sustained second-degree burn injuries covering most of its back. The application of CopaSil started three months after sustaining the burn injury when silver sulfadiazine topical cream treatment showed no significant improvement. CopaSil is formulated with ingredients that may help in reducing inflammation and accelerate healing by modulating the immune response. After using CopaSil for six months, the horse's back was healed, and the hair began to regrow. The complete healing was achieved within six months, and full recovery was reported and confirmed by the horse's owner and pharmacist. This case report highlights the outcomes and benefits of CopaSil in improving the appearance of scars.

Advantage effect of Dalbergia pinnata on wound healing and scar formation of burns.

ETHNOPHARMACOLOGICAL RELEVANCE: Dalbergia pinnata, as a natural and ethnic medicine in China, has been used for burns and wounds with a long history, which has the effect of invigorating blood and astringent sores. However, there were no reports on the advantage activity of burns. AIM OF STUDY: The purpose of this study was to screen out the best active extract part of Dalbergia pinnata and investigate its therapeutic effect on wound healing and scar resolution. MATERIALS AND METHODS: Rat burn model was established and the healing effects of extracts from Dalbergia pinnata on burn wounds were evaluated by the percentage of wound contraction and period of epithelialization. Histological observation, immunohistochemistry, immunofluorescence and ELISA were used for the examination of inflammatory factors, TGF-ß1, neovascularization and collagen fibers through the period of epithelialization. In addition, the effect of the optimal extraction site on fibroblast cells was evaluated by cell proliferation and cell migration assays. The extracts of Dalbergia pinnata were analyzed by UPLC-Q/TOF-MS or GC-MS technique. RESULTS: Compared to the model group, there were better wound healing, suppressed inflammatory factors, more neovascularization as well as newly formed collagen in the ethyl acetate extract (EAE) and petroleum ether extract (PEE) treatment groups. The ratio of Collagen I and Collagen III was lower in the EAE and PEE treatment groups, suggesting a potential for reduced scarring. Furthermore, EAE and PEE could repair wounds by up-regulating TGF-ß1 in the early stage of wound repair and down-regulating TGF-ß1 in the late stage. In vitro studies showed that both EAE and PEE were able to promote NIH/3T3 cells proliferation and migration compared with the control group. CONCLUSIONS: In this study, EAE and PEE were found to significantly accelerate wound repair and might have an inhibitory effect on the generation of scars. It was also hypothesized that the mechanism might be related to the regulation of TGF-ß1 secretion. This study provided an experimental basis for the development of topical drugs for the treatment of burns with Dalbergia pinnata.

Clinical application of traditional Chinese medicine moisture exposed burn ointment in the treatment of facial soft tissue defect.

OBJECTIVE: To introduce a new method of treating facial soft tissue defect by observing the clinical curative effects of traditional Chinese medicine moisture exposed burn ointment in treating facial soft tissue defect. METHODS: A total of 85 patients with facial soft tissue defects were treated with traditional Chinese medicine moisture exposed burn ointment, and the clinical therapeutic effects were analyzed by observing the wound healing time, scar formation and changes of facial appearance and functions. RESULTS: Of the 85 patients, the shortest wound healing time was 12 days and the longest was 72 days; the facial appearance and functions restored to be normal in 74 patients, with good skin elasticity and mild scar formation in the wound area; 11 patients were lost to the follow-up; two patients suffered from the longest wound healing time due to their skin defect of nasal tip and nasal columella and the cartilage defect of nasal wings, and V-shaped defects were left at the edge of the left nostrils after the wound healing, which may be attributed to the ineffectiveness of MEBT/MEBO on cartilage. CONCLUSION: Traditional Chinese medicine moisture exposed burn ointment can realize more satisfying healing effects when applied in the treatment of facial soft tissue defects, including user-friendly operation, no special requirements for medical devices, obviously lower treatment cost, etc., and thus it is an easy-to-operate and effective way for such patients, especially for elderly patients, patients with poor body conditions and patients unbearable to undergo complicated operations.

Evaluating efficacy and safety of the topical silicone gel containing onion extract in the treatment of post-cesarean surgical scars.

BACKGROUND: Cesarean section scars are post-surgical problems in women. Many active ingredients have been found to diminish scar formation. Clinical investigations on the onion extract have gained more attention due to its properties, such as improvement of scar appearance and texture. However, published studies evaluating the usefulness of the onion extract in the treatment of scars are controversial. METHODS: The three-month study period followed a prospective, randomized, and double-blinded design. Each enrolled subject's post-cesarean completely sealed wounds were divided into two halves along the closure axis. Each half was randomly assigned to the treatment with either silicone gel containing 5% onion extract or the silicone gel containing vitamin C. All subjects were respectively evaluated at the one, two, and three months of the treatment. RESULTS: After the three-month follow-up, there was a statistically significant difference in scar improvement between before and after treatment. None of statistically significant difference in the Patient and Observer Scar Assessment Scale (POSAS) and Vancouver Scar Scale (VSS) scores and melanin value was found between silicone gel containing 5% onion extract and the control silicone gel. However, the improvement of scar erythema by treatment with the silicone gel containing 5% onion extract was significantly greater than in the control group. No adverse effects were reported in either group.

[Advance in mechanisms of glial scarring after stroke and intervention of traditional Chinese medicine].

When ischemia or hemorrhagic stroke occurs, astrocytes are activated by a variety of endogenous regulatory factors to become reactive astrocytes. Subsequently, reactive astrocytes proliferate, differentiate, and migrate around the lesion to form glial scar with the participation of microglia, neuron-glial antigen 2(NG2) glial cells, and extracellular matrix. The role of glial scars at different stages of stroke injury is different. At the middle and late stages of the injury, the secreted chondroitin sulfate proteoglycan and chondroitin sulfate are the main blockers of axon regeneration and nerve function recovery. Targeted regulation of glial scars is an important pathway for neurological rehabilitation after stroke. Chinese medicine has been verified to be effective in stroke rehabilitation in clinical practice, possibly because it has the functions of promoting blood resupply, anti-inflammation, anti-oxidative stress, inhibiting cell proliferation and differentiation, and benign intervention in glial scars. This study reviewed the pathological process and signaling mechanisms of glial scarring after stroke, as well as the intervention of traditional Chinese medicine upon glial scar, aiming to provide theoretical reference and research evidence for developing Chinese medicine against stroke in view of targeting glial scarring.

N-Acetylcysteine Added to Local Anesthesia Reduces Scar Area and Width in Early Wound Healing-An Animal Model Study.

The aim of the study was to evaluate if a pre-incisional N-acetylcysteine (NAC) treatment altered the process of wound healing in a rat model. The dorsal skin of 24 Sprague-Dawley rats was incised in six locations. Before the incisions were made, skin was injected either with lidocaine and epinephrine (one side) or with these agents supplemented with 0.015%, 0.03%, or 0.045% NAC (contralaterally). Photographic documentation of the wound healing process was made at 11 time points. Rats were sacrificed 3, 7, 14, or 60 days after incision to excise scars for histological analysis. They included: Abramov scale scoring, histomorphometry analysis, and collagen fiber arrangement assessment. Skin pretreated with 0.03% NAC produced the shortest scars at all analyzed time points, though this result was statistically insignificant. At this NAC concentration the scars had smaller areas on the third day and were narrower on the day 4 compared with all the other groups (p < 0.05). On day 7, at the same concentration of NAC, the scars had a higher superficial concentration index (p = 0.03) and larger dermal proliferation area (p = 0.04). NAC addition to pre-incisional anesthetic solution decreased wound size and width at an early stage of scar formation at all concentrations; however, with optimal results at 0.03% concentration.

Use of hyaluronidase in plastic surgery: A review.

Hyaluronidase is a family of enzymes that degrade hyaluronic acid (HA). It is found to increase vascular permeability and temporarily disrupt the extracellular matrix, promoting diffusion of substances through tissues. Alongside its applications in ophthalmology, obstetrics and gynaecology, musculoskeletal medicine, radiology and drug and fluid administration, hyaluronidase has a number of roles in the field of plastic surgery. The popularity of HA fillers in recent years has led to an increase in the usage of hyaluronidase in the treatment of filler-related complications. The purpose of this article is to review the current and future uses of hyaluronidase within the field of plastic surgery. Hyaluronidase is used as an adjunct to local anaesthetics in skin infiltration, skin graft harvesting, tumescent analgesia, managing complications of dermal fillers, treatment of extravasation injury, prevention and management of oedema, treatment of ganglion and management of scars. However, it has some limitations. Hyaluronidase is known to interact with a number of common medications. Several case reports also highlight the risk of allergic reaction to the substance. Although rare and usually mild, hyaluronidase has the potential to cause anaphylaxis. Other adverse effects include bruising and swelling. Overall, hyaluronidase appears to be a very safe, cheap and effective medication for a variety of uses in the field of plastic surgery and beyond.

Tagitinin F has anti-inflammatory, anti-nociceptive and anti-matrix metalloproteinase properties: An in silico, in vitro and in vivo study.

Sesquiterpene lactones (SL) are natural bioactive molecules indicated as potential scaffolds for anti-inflammatory and analgesic drug design. However, their anti-inflammatory applicability remains underestimated since the impact of SL on inflammatory nociception and tissue repair are overlooked. Thus, we used an integrated in silico, in vitro and in vivo framework to investigate the impact of tagitinin F (TAG-F) on lipopolysaccharide (LPS)-challenged macrophages, excisional skin wounds, and carrageenan-induced paw edema and mechanical hyperalgesia in mice. RAW 264.7 macrophages in culture were challenged with LPS and treated with TAG-F (5, 10, 50 and 100 µM). The paw of BALB/c mice was injected with carrageenan and treated with 0.5% and 1% TAG-F. Excisional wounds were also produced in BALB/c mice and treated with 0.5% and 1% TAG-F. Our results indicated a consistent concentration-dependent downregulation in 5-lipoxygenase, cyclooxygenase 1 and 2 (COX-1 and COX-2), matrix metalloproteinase 1 and 2 (MMP-1 and MMP-2) activities; as well as attenuation in prostaglandin E2 (PGE2), leukotriene B4 (LTB4) and tumor necrosis factor-α (TNF-α) production in both in vitro and in vivo models. In vivo, TAG-F also attenuated carrageenan-induced paw edema and mechanical hyperalgesia in mice. From the excisional skin wound, TAG-F was still effective in reducing neutrophils and macrophages infiltration and stimulating collagen deposition in the scar tissue, accelerating tissue maturation. Together, our findings indicate that the anti-inflammatory effect of TAG-F is more comprehensive than previously suggested, exerting a significant impact on the control of edema, inflammatory pain and modulating central metabolic processes linked to skin wound healing.

To evaluate the aesthetic improvement of skin imperfections, a gelcream containing 10% of acetyl hexapeptide-8 (registered trademark Argireline®) was selected, that can be applied directly upon the lesion, followed by a light massage in the treated area for a few minutes RESULTS: The skin quality parameters (hydration, elasticity, sebum), photographs and investigators clinical assessment have been performed before and after the treatment and demonstrated that this cream significantly improved the skin values and the self-image expectation of each patient. No allergic reactions were documented during the period treatment CONCLUSIONS: The topical administration of this cosmeceutical cream is a safe and effective alternative to the invasive procedures, to improve the quality of life in patients with some skin disorders such as cancer, surgical scars, hidradenitis, aging wrinkles

Curcuma longa aqueous extract: A potential solution for the prevention of corneal scarring as a result of pterygium surgical excision (Review).

Curcumin has been used since ancient times as a treatment for a wide range of pathologies. For centuries, it has been considered to be an effective aid for common human diseases. Curcuma longa has been reported to possess various beneficial properties and actions, including anti­inflammatory, proapoptotic, antiangiogenic and cortisone­like actions. Pterygium is a degenerative disorder of the conjunctiva indicative of a strong inflammatory condition that requires surgical treatment, which often results in disfiguring sclerocorneal scars. The delay in the healing of superficial corneal wounds caused by topical administration of light­cortisone results in improved restoration of corneal functions and anatomy compared with physiological healing processes. The present review is focused on the medicinal properties of curcumin, the main component of Curcuma longa extract, in particular its strong cortisone­like effect, and its potential use for the prevention and treatment of sclerocorneal scars resulting from pterygium surgical excision.

The efficacy of onion extract in the management of subsequent abdominal hypertrophic scar formation.

OBJECTIVE: Development of postoperative scars is often a problem. This study aimed to evaluate the efficacy of gel containing Allium cepa extract, allantoin and heparin (Contractubex, Merz Pharmaceuticals GmbH, Frankfurt, Germany) in reducing scarring after a caesarean section by comparing it with a control group, and also intra-individually, using the Vancouver Scar Scale (VSS). METHOD: A total of 120 patients who underwent a second elective caesarean delivery and who presented with hypertrophic scar development after their first caesarean section were included in the study. A scar revision was performed for all patients during the second caesarean operation. Patients in the study group (n=60) were advised to apply the topical scar gel postoperatively for a period of 6 months. The control group (n=60) received no treatment. RESULTS: Significant reductions were observed in the vascularity, pigmentation and height subgroups of the VSS for those in the group who continued the treatment to 24 weeks. An intra-individual analysis showed that the gel effectively reduced scarring after the second caesarean section. CONCLUSION: The prophylactic use of the gel to reduce scar development offers better results for vascularity, pigmentation and height subscales of the VSS after surgical removal of the primary caesarean scar during the second caesarean section. The results were better both intra-individually, and also in comparison with the control group and support the use of a gel containing Allium cepa extract, allantoin and heparin to reduce scarring after a caesarean section.

Topical Scar Treatment Products for Wounds: A Systematic Review.

BACKGROUND: There is an increasing number of over-the-counter topical products that are said to prevent pathologic scar formation and improve scar cosmesis. However, robust clinical data are lacking to substantiate these claims and to guide selection of topical products. OBJECTIVE: To determine the effectiveness of topical scar management products, including silicone gel, Allium cepa onion extract, vitamin E, trolamine, and microporous tape. METHODS AND MATERIALS: A PubMed search (2005-2019) was performed to identify studies of topical scar management products. Randomized controlled trials (RCTs), quasi-RCTs, meta-analyses, and controlled clinical trials were included for analysis. RESULTS: A total of 34 trials were included in this study. Of the 16 trials investigating silicone gel sheets, numerous high-quality RCTs found that silicone gel sheets and silicone gels significantly improved scar outcomes. Only a limited number of studies supported the effectiveness of onion extract, vitamin E, trolamine, and microporous tape products. CONCLUSION: Silicone gel products are an effective noninvasive treatment to prevent formation of pathologic scars and improve mature scars. Further high-quality studies are needed to elucidate the long-term effectiveness of these therapies.

Prolonged Scar-in-a-Jar: an in vitro screening tool for anti-fibrotic therapies using biomarkers of extracellular matrix synthesis.

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a rapidly progressing disease with challenging management. To find novel effective therapies, better preclinical models are needed for the screening of anti-fibrotic compounds. Activated fibroblasts drive fibrogenesis and are the main cells responsible for the accumulation of extracellular matrix (ECM). Here, a prolonged Scar-in-a-Jar assay was combined with clinically validated biochemical markers of ECM synthesis to evaluate ECM synthesis over time. To validate the model as a drug screening tool for novel anti-fibrotic compounds, two approved compounds for IPF, nintedanib and pirfenidone, and a compound in development, omipalisib, were tested. METHODS: Primary human lung fibroblasts from healthy donors were cultured for 12 days in the presence of ficoll and were stimulated with TGF-ß1 with or without treatment with an ALK5/TGF-ß1 receptor kinase inhibitor (ALK5i), nintedanib, pirfenidone or the mTOR/PI3K inhibitor omipalisib (GSK2126458). Biomarkers of ECM synthesis were evaluated over time in cell supernatants using ELISAs to assess type I, III, IV, V and VI collagen formation (PRO-C1, PRO-C3, PRO-C4, PRO-C5, PRO-C6), fibronectin (FBN-C) deposition and α-smooth muscle actin (α-SMA) expression. RESULTS: TGF-ß1 induced synthesis of PRO-C1, PRO-C6 and FBN-C as compared with unstimulated fibroblasts at all timepoints, while PRO-C3 and α-SMA levels were not elevated until day 8. Elevated biomarkers were reduced by suppressing TGF-ß1 signalling with ALK5i. Nintedanib and omipalisib were able to reduce all biomarkers induced by TGF-ß1 in a concentration dependent manner, while pirfenidone had no effect on α-SMA. CONCLUSIONS: TGF-ß1 stimulated synthesis of type I, III and VI collagen, fibronectin and α-SMA but not type IV or V collagen. Synthesis was increased over time, although temporal profiles differed, and was modulated pharmacologically by ALK5i, nintedanib, pirfenidone and omipalisib. This prolonged 12-day Scar-in-a-Jar assay utilising biochemical markers of ECM synthesis provides a useful screening tool for novel anti-fibrotic compounds.

[Evaluation of advantages of Contractubex gel usage for postsurgical scars treatment in comparison with absence of systematized topical scars treatment of kids with congenital cleft lip and palate]. / Otsenka preimushchestv primeneniya gelya Kontraktubeks pri posleoperatsionnykh rubtsakh v sravnenii s otsutstviem sistematizirovannogo mestnogo lecheniya u detei s vrozhdennymi rasshchelinami verkhnei guby i neba.

OBJECTIVE: Is to evaluate the advantage of Contractubex gel with regards to influence on vascularisation, pigmentation, thickness, surface size, configuration, and elisticity of postsurgical scars of children (after cheilorinoplasty) in comparison to absence of systematized topical treatment. MATERIAL AND METHODS: Into the prospective, non-interventional, observational, multi-centered, in parallel groups, open, controlled study were included 60 patients aged 2,5 months and older with postsurgical scars after first cheilorinoplasty after 7-14 day after operation. Patients were randomized into 2 groups of 30 patients in each. I group - patients get applications of Contractubex gel 3 times a day (in the morning, in the afternoon, in the evening) in accordance with patient information leaflet. II group - control group with no regular therapy of of postsurgical scars (without treatment or without application of oils and gels with anticsarring action). The period of medicine usage - 9 months and more for each patient, the each patient observation duration is 18 months. RESULTS: After analysis of the primary as well as secondary efficacy criteria (total grade based on POSAS scale, reported by investigator/parent) after 3, 6, 12, 18 months of observation in both groups a positive statistically significant dynamics was registered. At the same time in the Contractubex group results were statistically significantly better than in the control group. Positive dynamics was achieved quickier in the main group than in the contol group and was to observe already after 3 months of therapy, during the whole treatment and observation phase, and after 18 months of therapy. Additionally conducted photodocumentation of postsurgical scar development dynamics in terms of the study confirms positive effect of surgery and absence of visual data regarding keloids or hyperthrophic scars formation in patients in both groups. Adverse events, i. a. pain, itch, burning, long-run hyperemia were not registered during the whole period os study. CONCLUSION: The conducted study has shown high efficacy and safety of Contractubex usage for the treatment of postsurgical scars of children with with congenital cleft lip and palate (from 2,5 months old). The statistically significant advantage of the therapy with Contractubex was demonstrated in comparison with the control group (with no regular topical treatment). The obtained results allow to recommend Contractubex gel as an effective and safe medicine for the treatment of scarring after surgeries for kids directly after sutures removal.

Light-Emitting Diode-Based Photodynamic Therapy for Photoaging, Scars, and Dyspigmentation: A Systematic Review.

BACKGROUND: Light-emitting diodes (LEDs) may be used as an activating light source for photosensitizers in photodynamic therapy (PDT), a form of noninvasive phototherapy. Photodynamic therapy for aesthetic dermatologic conditions has demonstrated skin rejuvenating effects. OBJECTIVE: To evaluate the safety and efficacy of PDT using LEDs to treat aesthetic dermatologic conditions including photoaged skin, scarring, and dyspigmentation. MATERIALS AND METHODS: A search of PubMed and EMBASE databases was conducted through May 31, 2019, to identify studies that used LEDs as a light source for PDT and evaluated cosmetic improvements as the primary outcome measure. RESULTS: A total of 24 original articles were included in the authors' systematic review. The available evidence supports methyl aminolevulinate or 5-aminolevulinic acid incubation followed by LED treatment for global improvement of skin quality, including smoother texture, reduction of rhytides, and improvement of scars. Histologic analysis for global skin improvement demonstrated increased collagen fibers and decreased elastin fibers after LED-mediated PDT. CONCLUSION: Light-emitting diode-based PDT seems to have beneficial effects for photoaging, scars and dyspigmentation. A paucity of high-quality studies using LED-based PDT for aesthetic outcomes was found, highlighting the need for well-designed randomized control trials on this topic.

[Recalcitrant cicatrizing conjunctivitis. Treatment of nine patients with rituximab]. / Conjuntivitis cicatrizal recalcitrante. Tratamiento de nueve pacientes con rituximab.

Cicatrizing conjunctivitis is the final consequence of several diseases. The most severe among them are cicatricial pemphigoid and chronic Stevens-Johnson syndrome. Systemic immunosuppressive drugs and steroids are usually an effective approach to these diseases. However, a few patients follow a recalcitrant course unremitting to usual therapy. We describe the treatment with rituximab of seven patients with cicatricial pemphigoid and two with chronic Stevens-Johnson syndrome. Eight of them also received gammaglobulin and all achieved clinical remission. Three relapsed and required two or three new courses of rituximab with good control of disease activity. Rituximab proved to be an efficacious drug for chronic recalcitrant cicatrizing conjunctivitis.

La conjuntivitis cicatrizal es la consecuencia de distintas enfermedades oculares. Entre ellas, las más graves son el penfigoide cicatrizal y el síndrome de Stevens-Johnson crónico. El tratamiento de estas enfermedades con corticoides e inmunosupresores es habitualmente exitoso, pero unos pocos pacientes siguen un curso recalcitrante. En los últimos años se introdujo el uso de rituximab, asociado o no a gammaglobulina endovenosa, en forma abierta, para el control de la inflamación conjuntival. Describimos aquí el tratamiento de siete pacientes con penfigoide y dos con Stevens-Johnson recalcitrante, con rituximab. Ocho recibieron también gammaglobulina y todos alcanzaron la remisión de la actividad. Tres recayeron y recibieron dos o tres nuevos cursos de la medicación con mejoría sintomática. El rituximab probó ser una droga efectiva para el tratamiento de la conjuntivitis cicatrizal crónica recalcitrante.
