RESUMO

Background: Lyme borreliosis is a multisystemic infection caused by the spirochete Borrelia burgdorferi. Erythema migras is the main clinical marker of the disease. Objective: This study aimed was to investigate the frequency and clinical manifestations of European borreliosis on the skin, and to determine the significance of these findings for diagnosis and therapy. Methods: A retrospective-prospective clinical study of outpatients treated and monitored in a private clinic of an infectologist was conducted over nine years from to 2013-2021. The study was clinical, descriptive and analytical in nature. Results: In the investigated period, 509 (30.8%) patients with borreliosis symptoms were treated. EM in our patients occurred under the following conditions: a) ringed redness, b) redness of target cels and d) continuous round or oval redness of different sizes of individual redness, or multiple occurrences with primary dissemination. Skin changes with multiorgan chronic symptoms of borreliosis occurred in 67.7% of cases the including: walking redness of different shapes and sizes, pink borreliosis stretch marks, white borreliosis stretch marks, borreliosis palms and soles, psoriatic changes, Acrodermatitis chronica atrophicans, Scleroderma circumscripta-morphae, Erythema nodosum, Granuloma anulare and Lichen striatus et atrophicans. Of the 509 patients treated for borreliosis, 32.3% with multi-organ symptomatology had no skin changes. Conclusion: The skin manifestations of European borreliosis are multi-layered and Erythema migrans are basic, but not the only markers of the disease. 'Pink borreliose stretch marks, "white borreliosis striae", "borreliosis palms or soles", and intermittent redness accompanied by itching are unique markers for the diagnosis of chronic borreliosis, if they are manifested.

RESUMO

INTRODUCTION: Striae distensae (SD), linear scars of derma, caused by disproportionate skin stretching, which indicates a cosmetic problem and even endangers individuals' psychosocial health. Microneedling, representing a relatively new procedural therapy, has shown brightening but diverse results in the remedy of SD. Our study systematically investigates and further evaluates the efficacy of microneedling for SD. METHOD: This study was conducted following the PRISMA guidelines. According to the preplanned search strategy, four electronic databases were comprehensively searched for eligible clinical controlled studies. Standardized mean difference (SMD) and odd ratio (OR) with 95% confidence intervals were calculated for continuous data and dichotomous data, respectively. RESULTS: According to the predetermined criteria, eleven eligible articles of six RCTs and five non-RCTs were included. Concerning clinical improvement, a significant difference was observed in the microneedle radiofrequency treatment subgroup (SMD: 0.57, 95% CI 0.20-0.94, P = 0.003). The pooled result of the second subgroup revealed that microneedling and lasers producing almost comparable effectiveness for treating SD with no significant difference (P = 0.35). The analysis result of the third subgroup of microneedling versus non-laser therapy indicated significant difference at the 5% significance level (SMD:1.01, 95% CI 0.51-1.51, P < 0.0001). With regard to patient satisfaction, the pooled estimate concluded that participants' satisfaction with therapeutic effect between MRF and laser group was comparable (P = 0.26), whereas microneedling exhibited significant superiority than both laser (P = 0.04) and non-laser treatments (SMD: 0.95, 95% CI 0.52-1.38, P < 0.0001). Occurrence of post-inflammatory hyperpigmentation (PIH) was not obvious in microneedling therapy compared to other treatments, and a statistically difference was observed (P = 0.0003). Microneedling treatment caused significant pain compared with laser therapy (P < 0.00001). CONCLUSION: This systematic review and meta-analysis has provided initial evidence of the efficacy and safety of microneedling technology for SD.

RESUMO

INTRODUCTION: Striae distensae (SD), or stretch marks, are a common skin problem having a psychological impact and cosmetic concern, especially for women, in whom the prevalence is higher than in men. This study assessed the efficacy and safety of a single autologous micrografting treatment (AMT®) using Rigenera® technology for the management of SD. METHODS: This single-centre study included 10 healthy women between 24 and 65 years of age, with Fitzpatrick-Goldman skin types I-IV, who had visible SD in glutes/thighs. Each subject acted as their own control. The treatment procedure (microneedling + AMT) and the control procedure (no treatment) were performed on contralateral sides of the glutes/thighs, targeting matched and paired SD. Microneedling was carried out using Dermapen®, equipped with 32 needle heads set at 1.5 mm needle length. The AMT procedure involved extracting biopsies from the mastoid hair zone with a 2.5-mm dermal punch, followed by disaggregation of the biopsies in a physiological saline solution using the Rigeneracons. The disaggregated micrografts were then intradermally injected using 30G 4-mm needles, maintaining a distance of 1 cm between injection points, covering the entire marked treatment region. RESULTS: In the treated area, at 3 months post-procedure compared to pre-procedure, the following changes were observed, all with statistical significance (P ≤ 0.05): (a) significant reductions in skin roughness (Ra, - 15.9%; Rz, - 22.6%), skin luminance (- 2.0%), and blue-green color distribution (- 10.6%); (b) significant increases in skin microcirculation maximum value (+ 240.1%), skin hydration (+ 71.2%), skin elasticity (+ 216.5%), skin density (+ 34.3%), skin thickness (+ 26.0%), and hypodermis thickness (+ 29.9%). Furthermore, for each of the aforementioned parameters, there was a significantly greater improvement observed with the AMT procedure compared with microneedling at 3 months (all P ≤ 0.05). CONCLUSION: The AMT procedure using Rigenera technology resulted in an noticeable improvement in the SD appearance after 3 months in healthy women.


This was a study of the Autologous Micrografting Technology (AMT) procedure for management of SD. Striae distensae (SD) commonly known as stretch marks are visible linear scars on the skin arising from excessive stretching of the skin. They are a very common condition, especially in women, causing cosmetic concern and psychological discomfort. Ten healthy women with SD were included in the study and each subject acted as their own control. Matched and paired SD on contralateral sides of the glutes/thighs were identified for treatment and control. In the area identified for treatment, the skin was initially damaged by microneedling to enhance regeneration, followed by intradermal injection of disaggregated autologous micrografts. The micrografts for the AMT procedure were extracted from the mastoid hair zone and disaggregated in physiological saline solution using the Rigeneracons. In the control area, no treatment was performed. The efficacy of the AMT procedure was assessed at 1 and 3 months post-procedure using several validated methodologies. Three months after the AMT procedure, a significant increase was observed in skin hydration, elasticity, density, and thickness, as well as in hypodermis thickness and microcirculation maximum value compared with pre-procedure in the treated area. There also was a significant reduction in skin roughness, skin luminance, and blue-green color distribution at 3 months in the treated area. For each of these parameters, the improvement observed at 3 months was significantly higher with the AMT procedure compared with only microneedling. We showed that a single AMT procedure using Rigenera technology is useful in the management of SD.

RESUMO

BACKGROUND: Striae Distensae (SD) is a common dermatological lesion. The mechanism of formation is unclear, the prevailing theory is mechanical pulling of the skin and hormonal changes. Traditional SD treatment methods include topical drugs, photoelectric therapy, stripping and others, but each has limitations. Stromal vascular fraction gel (SVF-gel) is a filler physically prepared from granular fat, enriched with adipose-derived stem cells (ADSCs) and extracellular matrix (ECM). A good effect in the treatment of neck lines, wounds, acne, and other aspects. SD formation and treatment goals are comparable to those of neck lines. In this study, SVF-gel filling will be used to treat mature SD, and its effectiveness and safety will be discussed in detail. METHODS: From December 2019 to June 2022, recruit patients who want to treat SD caused by obesity or pregnancy among those who have "autologous fat aspiration" to change their body shape. Preoperatively, the area to be treated for SD was marked, autologous fat aspiration was performed, and the aspirated fat was prepared as SVF-gel and filled into the preoperatively marked SD. All patients had preoperative and postoperative follow-up with planar photographs and VISIA skin analyzer photographs to assess surgical results and safety from subjective and objective perspectives. RESULTS: A total of 36 patients were enrolled, with 31 of them successfully followed up on. The mean Global Aesthetic Improvement Scale (GAIS) score six months after surgery was 1.87 ± 0.03. At six months postoperatively, the overall patient satisfaction rate was 90%. The depth, area, and color of SD improved six months after surgery, and no serious complications occurred in any of the patients. CONCLUSIONS: SVF-gel is a safe and effective method of improving mature SD and can be used as a clinical treatment option.

RESUMO

In autism spectrum disorders (ASDs) in the pediatric population, skin manifestations are generally attributable to the concomitance of allergic forms or to accidental, self-inflicted or abusive lesions. However, clinical evidence has highlighted the presence of an increasing number of abdominal stretch marks, probably caused by the increase in the number of obesity cases in the pediatric population, in general, and therefore also among children with ASD. Stretch marks are often attributed to obesity, as they have an incidence of more than 50% in obese individuals. In the first part of this article we hypothesized that in addition to obesity there are other factors, such as a structural alteration on the skin in people with ASD, which can contribute/aggravate the phenomenon of stretch marks. Despite the high frequency with which stretch marks are found in children with ASD, this aspect has never been studied, the structure of the skin of children with ASD is not known. Furthermore, it is not known whether this structure is different from that of subjects without ASD. In the second part of the article, we hypothesized the mechanisms of the negative impact of simple abdominal stretch marks on the symptomatic picture of children with ASD. The presence of stretch marks, altered tactile perception, altered sensitivity to clothing fabrics can be a combination that influences development and determines negative consequences in the neurological picture of a child with ASD, as it is already known that the altered sensory perception in children with ASD contributes to the deterioration of social behavior. Furthermore, the presence of stretch marks may play a role in the postural and motor defects of children with ASD.

RESUMO

The aims of this study were to characterize and to compare the structural alterations of collagen and elastic fibers in the abdominal stretch marks of patients submitted to intralesional and per quadrant (region close to stretch marks) Platelet-Rich Plasma (PRP) treatment, as well as, to establish the possible mechanisms of action of this treatment involving toll-like receptors (TLRs) signaling pathways and growth factors. Incisional biopsies were collected from abdominal stretch marks with a 2 mm diameter punch in female patients, at the beginning of treatment, after 6 and 12 weeks of treatment, and submitted to morphological analyzes of elastic and collagen fibers, and immunohistochemistry for TLRs signaling pathways and growth factors. Our results demonstrated PRP per quadrant treatment was most effective in reducing the area of the abdominal stretch marks, with consequent stimulation of the synthesis and remodeling of collagen and elastic fibers. Also, PRP per quadrant treatment promoted an increase in TLR2 and TLR4 immunoreactivities, with consequent increase in TNF-α, VEGF and IGF-1. Based on the current findings, PRP constitutes a promising therapeutic approach in patients with stretch marks, since it promoted modulation of inflammatory cytokines and growth factors, with consequent remodeling of extracellular matrix, culminating with tissue improvement.

RESUMO

INTRODUCTION: Stretch marks are common atrophic dermal scars with significant physical and psychological effects. Therefore, there is a need for effective cosmetics and procedures for stretch mark treatment. This study aimed to evaluate the efficacy and safety of a novel treatment for stretch marks that is made up of topical formulations containing beta-glucan combined with nanofractional radiofrequency. METHODS: This randomized, blinded control trial enrolled 64 Chinese women aged 20-45 years at > 6 months after delivery with obvious white or silver abdominal stretch marks. Participants were randomly allocated to group A (blank group), group B (topical product group), group C (product combined with nanofractional radiofrequency), and group D (vehicle combined with nanofractional radiofrequency). The stretch mark width, skin elasticity, skin color, skin thickness, and collagen density were noninvasively measured. Two trained assessors evaluated the severity, color, outline, and relaxation of the striae. RESULTS: Group C showed the best treatment efficacy, with no adverse effects observed during the study period. CONCLUSION: Our findings indicate that stretch mark treatment using topical formulations containing beta-glucan, combined with nanofractional radiofrequency plus magnetic nanofractional radiofrequency, is tolerable and effective. TRIAL REGISTRATION: ChiCTR2200056725.

RESUMO

Striae distensae (SD), also known as stretch marks, are observable linear scars that appear where dermal damage has occurred as a result of prolonged stretching of the skin. The actual pathophysiology of SD is still up for debate because its origins are multifaceted. Generally, striae are benign lesions, but larger lesions may get traumatized and become ulcerated or rupture. In patients with edema and receiving systemic steroids, bullous SD could develop secondary to fluid buildup preferentially in striae. We report a case of a young patient with cardiomyopathy who received systemic steroids and developed bullous striae distensae.

RESUMO

Striae (striae cutis distensae) are a common disfiguring skin condition, characterised by the appearance of linear bands on the skin, with an atrophic look. The striae development is still unknown, being more common in women than in men. The prevalence of this condition ranges from 50% to 90%. Regarding treatment, there are various treatment strategies currently available for stretch marks, including topical preparations such as tretinoin and glycolic acid, and also laser. The goal of this work is to discover the main treatments available for striae management. For that, a search was performed based on the definition of specific scientific keywords, by exploring PubMed, ScienceDirect and Biblioteca Virtual em Saúde (BVS). MeSH thesaurus (Medical Subject Headings) descriptors were used. The results indicate that, to date, no treatment is fully effective. More clinical trials are needed to validate the efficacy of these therapies and their long-term use in this type of skin lesion.

RESUMO

Striae distensae (stretch marks/striae gravidarum) is one of the common cosmetic problems that can cause psychological distress and anxiety to patients due to its disfiguring damage, especially for women. The etiology of striae distensae is currently unknown, and risk factors include low maternal age, family history of stretch marks, excessive weight gain during pregnancy, and high neonatal weight. This article reviews the latest literature on the most commonly used, most popular, and novel treatment modalities and analyzes the hot spots and difficulties in striae distensae treatment in recent years. Topical treatment modalities are mainly used as an adjunctive treatment. Ablative lasers and non-ablative lasers are the most popular, among which picosecond has been tried in striae distensae treatment in the last two years. Combined treatment modalities are currently a hot spot for SD treatment, and microneedle radiofrequency and fractional CO2 laser combined with other treatments are the most common. Microneedle radiofrequency is the most commonly used and achieved therapeutic effect among the combined treatment modalities.

RESUMO

A large part of the world's population suffers from Striae distensae (SD) or stretch marks, which create physical and psychological discomfort in people. We evaluate the SD clinical improvement by using a non-ablative fractional Nd:YAP 1340 nm laser. The research was performed on 25 patients of both sexes, with a mean age of 31 ± 13.09 years. Each patient underwent from a minimum of 3 to a maximum of 4 treatments, with an Nd:YAP (1340 nm) medical device, every four weeks, with 3- and 6-month follow-up, in these areas: back, abdomen, breast, flanks, lower limbs, buttocks, and thighs. Manchester Scar Scale assessed stretch marks improvement. Side effects, patient pain, and SD overall appearance improvement were also recorded for all patients. Digital photographs measured the aesthetic results. Treatment was well-tolerated (pain score 1.08 ± 0.76) by all patients. There were no long-term side effects, and 88% of patients revealed an SD excellent improvement showing good aesthetic results achieved by the treatment. The total mean pretreatment Manchester Scar Scale score decreased from 13.80 (±1.58) to 10.36 (±1.70) after 3 months (p < 0.01) and to 8.36 (±1.07) after 6 months (p < 0.01). An Nd:YAP (1340 nm) laser seems to be a safe and effective treatment, showing a higher security profile with no side effects.

RESUMO

Striae distensae (SD) or stretch marks are common linear scars of atrophic skin with disintegrating extracellular matrix (ECM) structures. Although fibroblasts contribute to the construction of ECM structure in SD, some studies have reported that mast cell degranulation causes the disruption of ECM in early SD lesions. Lagerstroemia indica flower (LIF) has traditionally been used in India as a diuretic. However, little is known about the effect and molecular action of Lagerstroemia indica flower extract (LIFE) on alleviating SD. This study evaluated the effects of LIFE on mast cell degranulation and the synthesis of ECM components in fibroblasts. LIFE inhibits the adhesion of rat basophilic leukemia (RBL) cells, RBL-2H3 on fibronectin (FN) and the expression of integrin, a receptor for FN, thereby reducing focal adhesion kinase (FAK) phosphorylation. In addition, LIFE attenuated the allergen-induced granules and cytokine interleukin 3 (IL-3) through the adhesion with FN. Moreover, the conditioned medium (CM) of activated mast cells decreases the synthesis of ECM components, and LIFE restores the abnormal expressions induced by activated mast cells. These results demonstrate that LIFE suppresses FN-induced mast cell activation and promotes the synthesis of ECM components in fibroblast, which indicates that LIFE may be a useful cosmetic agent for SD treatment.

RESUMO

Striae distensae (SD) are disfiguring skin condition causing cosmetic troubles and psychological distress. The aim was to compare the efficacy and safety of platelet-rich plasma (PRP) versus its combination with subcision or medium-depth peeling (glycolic acid 70% followed by trichloroacetic acid [TCA] 35%) for SD treatment. Seventy-five female patients with SD were divided into three equal groups with the contralateral side in each patients represented the control group. Group A treated with PRP, group B received PRP + subcision while group C received PRP + combined peeling (GA 70% + TCA 35%). Primary outcome included clinical improvement, patients' satisfaction, and Dermatology Life Quality Index (DLQI). Striae measurement, skin biopsies were also assessed. Very much improvement was achieved in 28%, 44%, and 36% in groups A, B, and C respectively. The combined groups (B and C) showed significantly higher patients' satisfaction and DLQI than group A (p = 0.03), (p < 0.0001). A significant decrease in all striae measurements was achieved with all groups (p < 0.001); however, groups B and C showed more decrease (p = 0.2 and 0.4). A highly significant decrease in the mean number of sessions was found in group B (p < 0.0001). All groups demonstrated improvement in dermal collagen deposition, which was higher in the combined groups. Side effects were mild and well tolerated. The combination of PRP with subcision or peeling was more effective and offered a higher therapeutic response than PRP alone. Moreover, the subcision has superior efficacy in striae albae and safer in darker skin types.

RESUMO

Striae distensae (SD) are common skin conditions that have posed a significant challenge regarding their assessment and treatment. The present study aimed to evaluate the efficacy of microneedling in comparison to fractional CO2 laser therapy. Similar striae were selected and photographed. Each side was randomly assigned to be treated with CO2 fractional laser or microneedling four times at monthly intervals and followed up for 10 months. Outcome measures including the length and width of the largest striae, dermatologist assessed improvement, patients' satisfaction, and visual analog scale (VAS) were assessed. Wilcoxon signed-rank test and Mann-Whitney U test were used to assess the efficacy of treatments. Forty patients with a mean age of 28.1 years were included. The median cross-section of the largest striae decreased significantly in both groups (P-value <0.001), without statistically significant differences between the two groups before and 6 months after treatment. VAS also improved significantly in both groups, and there were no statistically significant differences between the two treatments in all visits. No clinically significant adverse effects were observed. Fractional CO2 laser and microneedling are both efficient treatments to resolve SD. A new light should be shed on the microneedling modality as it is more economical than the other treatment options.

RESUMO

BACKGROUND: Striae distensae are atrophic dermal scars that can cause psychosocial distress among affected patients. Despite numerous available therapeutic modalities, no gold standard treatment has been established. OBJECTIVE: To evaluate the long-term efficacy and safety of a fractional 1064-nm picosecond laser for the treatment of striae alba in individuals with dark skin types. MATERIALS AND METHODS: Twenty volunteers with Fitzpatrick skin types IV-V who presented with striae alba were enrolled. Subjects were treated with a fractional 1064-nm picosecond laser for four sessions at 4-week intervals. The skin texture, average melanin index (MI), and melanin variation score were assessed using Antera 3D® before treatment, at 1 month after the second treatment, and at 1, 3, and 6 months after the last treatment. Two independent investigators evaluated clinical improvement by comparing pretreatment and posttreatment photographs. The patient satisfaction rates were likewise assessed. Adverse effects were recorded during the entire study period. RESULTS: Significant improvement of skin texture was seen at 1 month after the final treatment (p < 0.001) and continuously improved until the 6-month follow-up visit (p = 0.003). The average MI significantly increased at 1 month after the final treatment (p < 0.001), whereas the melanin variation score decreased throughout the follow-up period. Investigator assessment at the 6-month follow-up revealed that 90% of subjects had moderate to marked improvement of striae appearance. Only two of 20 subjects (10%) developed transient postinflammatory hyperpigmentation (PIH) after laser treatment. CONCLUSION: Fractional picosecond 1064-nm laser is effective and well-tolerated for the treatment of striae alba in dark-skinned individuals with a low incidence of PIH.

RESUMO

Authors present a study about the contraction forces observed in striae distensae fibroblasts (SMF) in a collagen scaffold. Collagen lattices were used to study the mechanical behavior of SDF within the collagen matrix compared to the lattices produced using the healthy skin derived fibroblasts (NSF). A Forcebox device was used to measure the contractile forces. Striae Rubrae fibroblast's contractile force was by 28% greater than that generated by the NSF and striae albae fibroblasts (P<0.05). Anomalies and especially differences in forces generated by SMF were observed through all our experiments. These findings complete and corroborate the results and information published in our previous studies. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

RESUMO

Background Striae distensae (SD) or stretch marks are a common dermatological condition where the dermis becomes scarred. This phenomenon is associated with many risk factors. This study aimed to evaluate the clinical variables and risk factors in patients with SD in Riyadh, Kingdom of Saudi Arabia (KSA). Methods A cross-sectional study was conducted to assess the clinical variables and risk factors for stretch marks among adults in Riyadh, KSA. An electronic questionnaire with an informed consent section was distributed randomly to a sample of adult patients in Riyadh city, KSA, from April to June 2021. A sample size of 512 participants was calculated using the Cochran formula (n = Z2pq/e2), considering 95% confidence and precision of at least ±5%. A 95% confidence level yielded Z values of 1.96, per the normal tables. Results A total of 512 participants were included in this study. This study found that 41.4% of the participants were aged 15 to 25 years of which, 70.4% of the participants were females, and 38.2% had a body mass index (BMI) of 24 or more. More than half of the participants (54.0%) indicated white skin color. The most prevalent area of striae, as reported by the participants, was the abdomen (57%). Around 19.1% of the participants with stretch marks stated that they were smokers, and 23.9% stated that they were obese o, had a chronic condition such as hypertension or diabetes mellitus. The majority of the participants (70.5%) had a family history of stretch marks. Conclusions This study showed that the prevalence of stretch marks was higher in females, younger participants, smokers, participants with a family history of stretch marks, and participants with a higher BMI and multiparity. More studies should be conducted to assess the correlations between these factors and the presence of stretch marks, and their influence on the quality of life of individuals.

RESUMO

BACKGROUND: Stretch marks (SM) are nowadays the most common aesthetic pathology of the body; in the XX century, it mainly affected pregnant women, while today it also affects teenagers during puberty, boys and girls without distinction. The aim of this study was to evaluate possible variations in the histological structure of the skin-in terms of quality/quantity of the extracellular matrix and of the collagen and elastic fibers-following the electromagnetic fields and negative pressure (V-EMF) treatment as regards hypotonia and SMs. MATERIALS AND METHODS: For the current study, 60 women, aged between 25 and 45, were examined. All of them presented deep, white or pearly white colored SMs having had them for between 12 and 25 years. These were documented, asking patients their level of satisfaction, through pictures and biopsies. All patients underwent a cycle of 6 or 8 weekly sessions; everyone was highly satisfied with the results obtained. RESULTS: Biopsies proved that the tissue was reorganized and restored to the original volume, characterized by the production of new, high-quality collagen and elastin molecules, by the reorganization of the basement membrane and by the correct positioning of the melanocytes. No side effects were observed during the treatments. This synergy stands as the most suitable treatment of striae rubra and alba. CONCLUSION: V-EMF enhances the keratinocyte migration base, melanocytes, and promotes neoangiogenesis with the result of improvement in the SM.
