Introduction and Hypothesis: The high prevalence of pelvic organ prolapse (POP) and related complications shows the necessity of early identification of risk factors. It is considered that striae and POP share a similar physiopathology. However, the link between the two is still inconclusive and requires further investigation. We conducted this study to evaluate the association between striae and POP. Methods: Databases such as PubMed, Embase, Cochrane Library, Scopus, Web of Science, and Google Scholar were searched to find relevant literature from inception up to May 2023. Full-text articles published in English or other languages and observational studies were included. The statistical analysis was performed using STATA 14.2. The random effects model was performed and heterogeneity was ≥ 50%. Statistical tools such as the Chi-squared test and the I2 index were used to calculate the level of heterogeneity among studies. Additionally, we utilized Funnel plots and Egger tests to assess the presence of publication bias. Results: Seven studies were selected for meta-analysis, yielding a total of 605 patients and 660 control subjects, to assess the link between striae and POP. The overall pooled odds ratio (OR) was 2.08 (95% confidence interval 1.04–4.19, I2 = 80.40%). Our analysis revealed a strong relationship between POP and striae (p < 0.001). Conclusions: This study recommends that stretch marks may be used as a helpful indicator of the risk for POP. Evaluation of striae as a risk factor and screening tool for detecting women at risk for the development of POP should be addressed in future well-designed studies. However, there is a need for high-quality studies in this field owing to the low quality of evidence. [ABSTRACT FROM AUTHOR]

Striae distensae (SD) present in women undergoing further breast surgery such as augmentation or mastopexy, can impact dramatically on outcomes both aesthetically and functionally. No technique has been described to address these. We describe our novel technique for management including intra-dermal nano-fat graft at the time of breast augmentation or mastopexy, followed by post-operative CO2 laser. Twenty patients have been treated with this technique in order to improve aesthetic outcomes and reduce complications such as SD worsening, poor scarring and ptosis. Level of evidence: Level IV, Therapeutic [ABSTRACT FROM AUTHOR]

Introduction: Striae distensae are a permanent skin defect that can affect 50%–90% of the population. The appearance of the changes resembles spindle‐shaped skin bands. The skin in this area is wrinkled, thin and looks like a scar. Most often, the changes are found on the skin of the abdomen, buttocks, breasts, thighs, and back. The appearance of striae means that the skin in this area has no hair follicles, sebaceous, and sweat glands. This skin is flabby, not very elastic and, what is very characteristic, the pigmentation of the skin affected by striae is much lower than in healthy skin. Cosmetology in the 21st century is developing very dynamically, new technologies are being developed, new cosmetological devices are being created and combined with treatments that have been known for a long time. Today's science offers hope for people who have struggled with reducing striae for many years and nowadays, nothing is impossible. Aims: The objective of this article is to provide information about cosmetological treatment used to reduce striae. Methods: In this article, we reviewed the published literature, article published in peer‐reviewed journals. Results: Today's cosmetology offers a wide range of numerous treatments, but the best results are achieved through a synergy of two or more treatments. But we should not forget that we should respond to each customer individually. Conclusion: The striae are not a problem that should be ignored. The beauty therapist is able to reduce them and help the client to improve the appearance of their skin. [ABSTRACT FROM AUTHOR]

Abstract Background Striae distensae is a disfiguring atrophic skin condition that impairs the body’s aesthetic image. Despite the variety of conducted studies, there is controversy regarding the best modalities. Human mesenchymal stem cells are considered a rich source for scar treatment. Skin needling is among the most efficient and safe aesthetic and therapeutic devices. This study aimed to evaluate the efficacy of the combination of needling and intradermal injection of mesenchymal stem cells compared to skin needling alone for treating striae distensae. Method This study was a randomized, double-blind clinical trial involving 10 women aged 18–60. Each striae lesion was divided into two parts, with one side receiving needling and intradermal injection of conditioned medium, while the other side received needling and intradermal injection of normal saline. This treatment was administered in three sessions with three-week intervals. Patients were evaluated before the first intervention and three months after the final session. Three months after the completion of the intervention, patients’ lesions were evaluated using biometric criteria, physician evaluation, and patient self-assessment. Results The results demonstrated a significant improvement in dermal and complete thickness and skin density in patients treated with microneedling. All skin ultrasound parameters improved significantly in patients receiving the combination of needling and conditioned medium. When comparing the two groups, significantly higher physician and patient satisfaction was observed in the combination group. However, the comparison of biometric indices improvement wasn’t significant between these groups. Conclusion The combination of human mesenchymal stem cells with microneedling could be considered a novel effective option for stretch marks.

Stretch marks are far from exclusively appearing on pregnant women and appear whenever the body experiences rapid growth. Collagen fibres are altered in the dermis, which is associated with a loss of orientation, and the elastic network is disrupted, leading to a fibrotic organisation. This results in epidermal tearing that produces skin lesions. Centella asiatica (CAST) is a well-known medicinal plant rich in active triterpenic molecules and traditionally used to treat wounds and help skin repair. The aim of this study was to evaluate CAST extract as a natural way to solve stretch mark concerns and understand its mechanism of action. Fibroblast proliferation based on scratch assay model and their gene expression by RT-qPCR was first evaluated. At the ex vivo level, elastin fibres were quantified by immunofluorescence. The orientation of the collagen fibres and their occupation of the dermis were analysed after Sirius red staining and specific software analysis. We showed that CAST stimulated fibroblast proliferation and reduced extracellular matrix degradation and fibrosis. On a stretch-marked skin explant, CAST increased the occupation of collagen fibres and elastin production. Based on the mechanisms behind the formation of stretch marks, CAST restored the dermis network by optimising fibre organisation for a visible skin remodelling effect. [ABSTRACT FROM AUTHOR]

Radiofrequency microneedling (RFM) has recently become a popular choice for the treatment of various dermatologic conditions and rejuvenation. Many studies have sought to evaluate the efficacy of RFM. However, its role in the management of these conditions remains unclear. A comprehensive literature search including randomized controlled trials, cohort studies, and case series evaluating the efficacy of RFM in various skin conditions was performed. In this review, we discuss the history and mechanism of RFM, describe various device features, and discuss the use of RFM in various skin conditions and rejuvenation. [ABSTRACT FROM AUTHOR]

The results of studying the effect of filamentary striae with birefringence 3 to 15 nm/cm in sitall [glass-ceramic] SO-115M on the quality of manufacturing of optical components of ring lasers and the accuracy characteristics of laser gyroscopes based on them are presented. It is shown that the presence of streaks with stresses not exceeding 15 nm/cm in sitall SO-115M does not affect the manufacturing accuracy of the resonator optical circuit and its assembly quality. The streaks in the output mirror of a ring laser serve as a source of additional backscattering and can increase the lock-in zone width. Proper adjustment of the output mirror makes it possible to reduce the amount of scattering and minimize the growth of the lock-in zone in a laser gyroscope. It is shown that the accuracy of a laser gyroscope is determined by the quality of the mirror substrates, the body geometry, and the level of backscattering inside the resonator.

Background: Striae distensae are atrophic scars that are often cosmetically distressing. The efficacy of fractional carbon dioxide (CO2) laser and platelet-rich plasma (PRP) in treating striae individually has been evaluated previously. However, not many studies described the combined efficacy of both. Aims and Objectives: The aim of this study was to compare the efficacy and safety of fractional CO2 laser alone and in combination with PRP. Materials and Methods: Twenty-four patients with striae presenting bilaterally in the abdomen, upper limbs, and lower limbs were included. PRP was prepared by double-spin method and cell count was done to ensure at least fourfold concentration of platelets. The patients were treated CO2 laser on both sides and PRP on the left side along with laser, every month for three sessions. Digital photography and dermoscopy were done at baseline, every treatment session, and 6 months after treatment. Clinical improvement was assessed by comparing photographs and patient satisfaction before and after treatment. Results: All patients showed improvement on both sides. In CO2-laser-treated patients, responses in 6 patients (25%) were moderate, 14 (56%) were good, and 4 (16.6%) were excellent. In CO2-laser and PRP-treated patients, responses in 5 patients (20.8%) were moderate, 11 (45.8%) were good, and 8 (33.3%) were excellent. Hyperpigmentation was the most common side-effect seen (19 patients) on both sides, which resolved spontaneously by 6 months. Conclusion: These results support the use of ablative CO2 fractional laser as effective and safe treatment modalities for striae. However, slightly better efficacy was noted with the addition of PRP.

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. [ABSTRACT FROM AUTHOR]

Striae are common dermal lesions associated with physiological and psychological alterations, affecting the quality of life. This proposed randomized controlled trial protocol will evaluate the clinical efficacy and treatment safety of fractional CO2 laser versus fractional radiofrequency (FRF) in clinical trials. We will randomly allocate 60 subjects who present abdominal striae into two different groups for the treatment, which will be performed once a month for a 3-month period. The results will be assessed by quartile scoring criteria; by comparing digital photos taken before and after each treatment; and also, by the measurement of cutaneous temperature, skin pH, and elasticity before and after the treatment. This paper describes the rationale and the design of the randomized controlled trial, which may provide evidence for clinical application of the methodology and the quality related to the efficacy and safety of fractional CO2 laser versus the FRF protocol for striae treatment.

Objective: When using laser therapy to effectively treat scars, the choice of treatment parameters depends on the knowledge accuracy of the underlying scar pathology, which is often difficult to judge by gross physical exam. As such, more quantitative measures are needed. In recent years, optical coherencetomography (OCT) has shown promise as a real-time imaging technolgoy of skin microstructure. A key step in developing a methodology for utilizing OCT to develop a comprehensive 'atlas' of OCT characteristics of a wide variety of scar types. This atlas may then be used as a tool for selecting the optimal treatment modality and parameters for each scar type.Methods: One hundred and fifty scars of a wide range of anatomical locations were imaged using OCT, capturing both vascular and structural data. A variety of scar etiologies (e.g. burn, surgical, traumatic) and types (e.g. hypertrophic, keloidal, atrophic) were included. Comparator scans were also taken from normal, unscarred skin.Results: OCT revealed morphological differences in the epidermis and dermis between scars and normal tissue, and between scar subtypes. Features affected by scar pathology included epidermal thickness, skin surface texture, dermal epidermal junction rugosity, blood vessel density, vessel shape and diameter, vessel direction and vascular network, dermis scattering intensity and non-uniformity. Each scar subtype showed consistent characteristics distinct from other scar subtypes.Limitations: This was a single-site study of a patient population in South Florida.Conclusion: OCT is a powerful new objective tool for the clinician to utilize in the pursuit of effective laser treatment parameters by enabling personalized treatment based on individual scar characteristics in order to maximize treatment capabilities.

Striae gravidarum (SG) is a kind of dermal scar associated with psychosocial and therapeutic challenge. Topical reagents and non‐invasive laser are more preferred than invasive procedures for less pain and shorter downtime. However, there are few studies on comparing and combining these two modalities. The aim of the present study was to evaluate the efficacy and tolerance of a topical regimen containing β‐glucan, 1565‐nm non‐ablative fractional laser (NAFL; ResurFX), and combination of them for SG. A total of 128 unilateral abdomens from 64 subjects were randomly divided into four strategies and were followed up for 12 weeks: topical vehicle (Veh); topical β‐glucan (B); 1565‐nm NAFL combined topical vehicle (NAFL); 1565‐nm NAFL combined topical β‐glucan (B + NAFL). NAFL was applied three times with a 4‐week interval. Topical reagent was applied b.i.d. for 12 weeks. Global Aesthetic Improvement Scale (GAIS) scores were assessed by blinded physician according to standard photograph, and by subjects at 12th week. The degree of SG atrophy was assessed by blinded physician before treatment and at the 12th week according to a standard 5‐point scale. Collagen remodeling was evaluated by histological analysis and all adverse effects were recorded. A total of 56 women (112 unilateral abdomens) completed all study. The GAIS scores by blinded physician showed greater improvement in NAFL as compared with β‐glucan, and by subjects showed greater improvement in β‐glucan as compared with vehicle. In terms of striae atrophy scale, the improvement of SG atrophy was more prominent in NAFL compared to β‐glucan, and in β‐glucan + NAFL compared to Veh + NAFL. All treatments were well tolerated. Topical β‐glucan regimen can mildly improve SG. NAFL showed better results than topical β‐glucan regimen. The combined strategy may further improve the SG atrophy compared with single treatment strategy. [ABSTRACT FROM AUTHOR]

Objective(s): To compare the presence and severity of striae gravidarum in pregnant women with and without stress urinary incontinence and to evaluate whether there is a relationship between the severity of striae gravidarum and the severity of incontinence in pregnant women with stress urinary incontinence.Study Design: Healthy primigravid pregnant women with an uneventful singleton pregnancy at 36-37 weeks of gestation were included. All women were asked two questions to assess the presence of urinary incontinence. Women who answered 'yes' to the question 'Do you have any involuntary urinary leakage during coughing/laughing/sneezing/running/jumping?' and 'no' to the question 'Do you have any involuntary urinary leakage accompanied by a strong urge to void?' were classified as women with stress urinary incontinence, and women who answered 'no' to both questions were classified as women without stress urinary incontinence. The presence and severity of striae gravidarum of these two groups were evaluated with the Davey score, and the severity of incontinence of women with stress urinary incontinence was evaluated with the Incontinence severity index questionnaire.Results: The Davey score of pregnant women with stress urinary incontinence was significantly higher than the score of women without stress urinary incontinence and the presence of severe striae gravidarum was more common in women with stress urinary incontinence. There was a positive, significant correlation between Incontinence severity index and Davey scores in women with stress urinary incontinence, and this was the only independent correlation that was significant in linear regression analysis.Conclusion(s): Presence and severity of striae gravidarum is correlated with the presence and severity of stress urinary incontinence in primigravid pregnant women. Evaluation of striae gravidarum may be useful in predicting the development of stress urinary incontinence and taking necessary precautions against it. This issue should be evaluated with good quality studies. [ABSTRACT FROM AUTHOR]

Abstract Background The current fact of increasing rates of cesarean deliveries is a catastrophe. Recurrent cesareans result in intraperitoneal adhesions that would lead to maternal morbidity during delivery. Great efforts are directed towards the prediction of intraperitoneal adhesions to provide the best care for laboring women. The aim of the current study was to evaluate the role of abdominal striae and cesarean scar characters in the prediction of intraperitoneal adhesions. Methods This was a case- control study conducted in the emergency ward of the obstetrics and gynecology department of a tertiary hospital from June to December 2019. The study was carried on patients admitted to the ward fulfilling particular inclusion and exclusion criteria. The study included two groups, group one was assessed for the presence of striae, and the degree of intraperitoneal adhesions was evaluated during the current cesarean section. Group two included patients without evidence of abdominal striae. They were evaluated for the severity of adhesions also after evaluation of the previous scar. Evaluation of the striae was done using Davey’s scoring system. The scar was assessed using the Vancouver Scar Scale. The modified Nair’s scoring system was used to evaluate intraperitoneal adhesions. Results The study group included 203 women, while the control group included 205 women. There were significant differences in the demographic characters of the recruited patients (p-value 0.001 for almost all variables). The mean Davey score in those with mild, moderate, and severe striae was 1.82 ± 0.39, 3.57 ± 0.5, and 6.73 ± 0.94, respectively (p-value

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. [ABSTRACT FROM AUTHOR]

The long-term survival of patients with cancer has risen dramatically during the last few decades. Despite this remarkable success, the same treatments that have enabled cure or remission often secondarily affect the skin, hair, and nails. Conditions including scarring, striae distensae, persistent alopecia, pigmentary changes, nail alterations, chronic radiation dermatitis, and radiation fibrosis have been associated with anxiety, depression, decreased quality of life, and impaired function. These dermatologic changes are cosmetically disfiguring, may limit activities, and are a visual reminder of past illness. Interventions toward improving these untoward sequelae and restoring the appearance and function of skin and appendages are critical for normalization and may contribute to improved quality of life in cancer survivors. Here, we outline dermatologic sequelae of cancer therapies with a review of medical and procedural treatment strategies to restore dermatologic health in the survivorship population.

Background and Objective: There is no validated instrument to assess the clinical severity of striae distensae. Here, we aimed to develop a striae distensae severity scale. Material and Methods: After a Delphi‐based consensus, 15 items related to striae severity were assessed in 110 areas (breasts, abdomen, and buttocks) from 45 participants. The items were analyzed through a partial least squares model to select the most important variables. To assess the reliability of the scale, 43 areas were retested. Results: Of the 110 areas evaluated, 34 were breasts, 24 abdomens, and 52 buttocks. Striae were considered mild in 30% of the evaluations, moderate in 33%, severe in 21%, and extremely severe in 16%. The final model was composed by: width of the widest striae, width of the striae with the most frequent pattern, atrophy, number of affected quadrants, distribution (multiple or isolated), hypo or hyperchromia and topography. The scores of the scale demonstrated a high correlation with the clinical classification (rho = 0.77). There was a high agreement in the scores from the reassessed areas (intraclass correlation coefficient = 0.90). Conclusion: An objective and reliable scale to assess the clinical severity of striae distensae on the breasts, abdomen, and buttocks was developed. [ABSTRACT FROM AUTHOR]

Striae distansae (SD) or stretch marks are very common, asymptomatic, skin condition frequently seen among females between 5 to 50 years of ages. It often causes cosmetic morbidity and psychological distress, particularly in women and in certain professions where physical appearances have significant importance. Of late, with the increasing emphasis on cosmetic management and awareness, patients approach dermatologists for stretch marks treatment. However, despite several advances, no fully effective treatment has emerged. Unfortunately, there is paucity of the strong evidence in the literature for the effective treatment of striae. A literature search using the terms 'striae distansae (SD or stretch marks' was carried out in the PubMed, Google Scholar and Medline databases. Only articles related to the treatment were considered and analysed for their data. Commonly cited treatments include topical treatments like tretinoin, glycolic acid, ascorbic acid and various lasers including (like) carbon dioxide, Er:YAG, diode, Q-switched Nd:YAG, pulse dye and excimer laser. Other devices like radiofrequency, phototherapy and therapies like platelet rich plasma, chemical peeling, microdermabrasion, needling, carboxytherapy and galvanopuncture have also been used with variable success. This article reviews all currently accepted modalities and their effectiveness in the treatment of stretch marks.

Higher scores for the parameters of the Vancouver scale were present in patients with severe striae (1.69 ± 1.01, 1.73 ± 0.57, 2.67 ± 1.23, and 1.35 ± 1.06 for scar vascularity, pigmentation, pliability, and height respectively with a p-value of < 0.001 each). Thick intraperitoneal adhesions were noted significantly in women with severe striae [21 (43.75%), p-value < 0.001)]. The Davey's and Vancouver scores showed highly significant predictive performance in the prediction of intraperitoneal adhesions (p-value < 0.001).Conclusion: Abdominal striae and cesarean scar were significant predictors for intraperitoneal adhesions.

The Köebner phenomenon (isomorphic response) is defined as the development of typical lesions of a dermatosis that occur in areas of trauma in previously uninvolved skin. Rare reports have suggested that striae are a form of injury to the skin that can result in koebnerization of psoriasis, vitiligo, and lichen planus. We herein report a 27-year-old female patient with plaque psoriasis who developed psoriatic lesions along striae distensae.

Supersonic shear imaging is a non-invasive technique used for detecting physiologic and pathologic changes in biological tissues. In this study, supersonic shear imaging was used to measure and compare shear wave speed (cs) and normalized elastic modulus (EN) values of skin with and skin without dermal striae (DS) in vivo. The values were measured at angles of 0°, 45°, 90° and 315° to the skin tension lines. In the presence of DS, a statistically significant reduction in the elasticity dermis was observed (p value <0.05). The mean values of cs and EN for STLs were higher in normal skin at 45° (4.26 ± 1.05 m/s and 56.23 ± 25.31 kPa) and 90° (4.26 ± 0.55 m/s and 54.91 ± 14.22 kPa), and those for DS were also higher at 45° (3.59 ± 0.72 m/s and 42.71 ± 27.97 kPa) and 90° (3.52 ± 0.65 m/s and 42.34 ± 31.68 kPa) than at other angles. Supersonic shear imaging was found to be a promising technique in the study of skin with DS. The data obtained in this study are expected to be relevant for future studies using shear wave elastography for the aforementioned purpose. [ABSTRACT FROM AUTHOR]

Platelet‐rich plasma (PRP) has recently become a popular treatment for various skin conditions, including striae distensae, acne scars, traumatic scars, hair regrowth, and cutaneous rejuvenation. Although PRP has been utilized in orthopedics for many years, its recent entry into dermatology has been met with controversy. While the recent research has generally been limited and is often contradictory, this has differed from the persuasive marketing campaigns targeting patients and consumers. Aesthetic practitioners should be knowledgeable with the available evidence for PRP in the treatment of striae distensae. Here, we review the pertinent literature and offer additional insights.

Background: Striae distensae (SD) are visible linear scars in areas of dermal damage due to excessive stretching of the skin. Striae can cause cosmetic morbidity and psychological distress, particularly in women. In spite of several advances, no definitive treatment has emerged. Aim: The aim of this study was to evaluate the efficacy of microneedling versus cryoroller liquid nitrogen therapy in the management of striae distensae both clinically and histopathologically. Methodology: Striae of all 27 patients were treated with needling and cryoroller liquid nitrogen therapy on two different sides of each patient. Digital photography and skin biopsy were done to assess clinical and histopathological improvement. Results: On the evaluation of clinical response, poor clinical response (=25%) was seen in 92.6% (n = 25) of patients on the dermaroller side, followed by moderate clinical response and on the cryoroller side, poor clinical response was seen in all 27 patients. Comparing the two sides, on the dermaroller side, 77.8% (n = 21) were satisfied and on the cryoroller side, 55.6% (n = 15) of the patients were slightly satisfied and 29.6% (n = 8) were satisfied. The histopathological improvement was almost similar on both dermaroller and cryoroller sides. Conclusion: Both microneedling with dermaroller and liquid nitrogen cryoroller were found to be safe and partially effective methods to treat striae. Patients were more satisfied with microneedling than cryoroller. [ABSTRACT FROM AUTHOR]

Background: Various treatment modalities have been applied to treat striae alba (SA) with low satisfaction rate. Fractional microneedling radiofrequency (FMR) provides deep dermal coagulation, thereby inducing collagen synthesis and tissue tightening. The addition of platelet‐derived lyophilized growth factors may add to the effect of FMR. Objectives: To evaluate and compare the efficacy and safety of FMR alone or combined with lyophilized growth factors in the treatment of SA. Methods: In this left‐right comparative study, 25 patients suffering from SA on the abdomen received four sessions of FMR with lyophilized growth factors on one side and with saline (as placebo) on the other side at 4 weeks interval. Photographic and biopsy documentation of the progress of the SA was carried out before the start of the treatment and 4 weeks after the last session. Calculation of the width of SA before treatment and after 4 sessions was done by Adobe Photoshop CS6. Results: There was a significant improvement in SA width after treatment in both the lyophilized growth factors (P = <.0001) and placebo sides (P = <.0001), the lyophilized growth factors being superior (P =.002). Patient satisfaction was more on the lyophilized growth factors (LGF) side (P =.034). Erythema and hyperpigmentation were less on the lyophilized growth factors side. Histopathologically, both showed improvement with no difference between LGF and placebo (epidermal thickness (P =.456), collagen content (P =.297), elastin content (P =.239)). Conclusion: The combination of FMR and lyophilized growth factors improves SA outcome. [ABSTRACT FROM AUTHOR]

Background and Objective: The improvement in the appearance of the skin with dermal striae (DS) is currently eval‐uated by invasive methods, such as biopsy. This study evaluates whether high‐resolution ultrasound (HRUS) could be used to identify skin lesions in vivo caused by DS, using 2D images and measuring the thickness of the dermal layer. Methods: High‐resolution ultrasound at frequencies of 20 and 30 MHz was used in this study in ten volunteers with DS. The thickness of the skin layers was estimated by tracing five vertical lines from epidermis (EP) to dermis (DE) and DE to hypodermis (H) surface. Results: The dermal lesions caused by striae appeared in ultrasonic images as poor echo areas. The average normal DE thickness varied from 1.07 to 1.65 mm, while the DE thickness with DS varied between 0.35 and 1.33 mm. A statistically significant reduction in the DE thickness was found (P‐value <.05) in the presence of DS. The mean values of the EP thickness without and with DS were 0.12 ± 0.03 mm and 0.11 ± 0.02 mm, respec‐tively. A total of 90.00% of the EP‐related groups did not present the normal distribu‐tion (P‐value <.05). Conclusions: High‐resolution ultrasound permitted the visualization of the three skin layers and the dermal lesions caused by striae. The dermal layer thicknesses with striae were thinner than those without. Therefore, ultrasound 2D imaging has shown to be a promising and financially feasible tool to be used as a noninvasive diagnostic method for evaluating therapeutic protocols used in the treatment of these dermal conditions.

A previously undescribed skin abnormality, referred to as "linear skin markings" (LSM), has been identified in free‐ranging common bottlenose dolphins (Tursiops truncatus) in the Indian River Lagoon, Florida (IRL). The lesions were identified during photo‐identification surveys conducted from 2002 and 2015. LSM presented as distinct, parallel lines running dorso‐ventrally on the torso and varied in length and width. The goals of this study were to determine (1) prevalence of the condition in IRL dolphins, (2) age and sex distribution of affected animals, (3) spatial and temporal distribution patterns, (4) duration of the condition, and (5) development of hypotheses regarding the etiology of the condition. Among 1,357 individual dolphins identified during the study period, 96 (7.0%) showed evidence of LSM. Nearly all (98.8%) cases with an established home range occurred in the northern and central regions of the IRL. The majority of cases of known sex were female (85%), of which 100% had given birth to one or more calves. The mean age of animals with LSM when first observed was 7.3 with a range of 1–20 years. The maximum observed duration of LSM was 15 years. Once observed, the condition persisted indefinitely. The etiology of LSM has not been established. [ABSTRACT FROM AUTHOR]

The concept of beauty has been changing recently. Due to this change and the advances in cosmetology, atrophic scars and striae distance are becoming exceedingly important in the everyday practice of dermatologists. Although these are very common pathologies, effective treatment seems impossible due to the high expectations of the patients. This article aims at reviewing the recent treatment alternatives for atrophic scars and striae. [ABSTRACT FROM AUTHOR]

Adolescent striae are more common in girls. The striae in boys can be misinterpreted as a result of non-accidental injuries such as physical abuses and violence. We reported a case of a 16-year-old boy who presented with multiple linear purplish striae on the upper trunk and both axillae area. The skin lesion was initially interpreted as lesions resulted from physical abuse and bully activities at his school. The parent was concerned about the skin lesions and they thought their son had been assaulted at school. The diagnosis of physiological striae in adolescence was made after excluding other endocrine disorders and related diseases. Further assessment revealed there was no history of recent physical assaulted at his school. This case illustrates that the unfamiliarity with this skin condition can be resulted in misinterpretation of the cases. However, suspiciousness for non-accidental injury is crucial, especially among adolescent groups who are at risk to be involved in the bully activities. The misinterpreted of the adolescent striae may cause stress to the parent or other family members and it has sometimes led to the unnecessary legal acts which might be taken by the protective parent.

Striae distansae (SD) or stretch marks are very common, asymptomatic, skin condition frequently seen among females between 5 to 50 years of ages. It often causes cosmetic morbidity and psychological distress, particularly in women and in certain professions where physical appearances have significant importance. Of late, with the increasing emphasis on cosmetic management and awareness, patients approach dermatologists for stretch marks treatment. However, despite several advances, no fully effective treatment has emerged. Unfortunately, there is paucity of the strong evidence in the literature for the effective treatment of striae. A literature search using the terms 'striae distansae (SD or stretch marks' was carried out in the PubMed, Google Scholar and Medline databases. Only articles related to the treatment were considered and analysed for their data. Commonly cited treatments include topical treatments like tretinoin, glycolic acid, ascorbic acid and various lasers including (like) carbon dioxide, Er:YAG, diode, Q-switched Nd:YAG, pulse dye and excimer laser. Other devices like radiofrequency, phototherapy and therapies like platelet rich plasma, chemical peeling, microdermabrasion, needling, carboxytherapy and galvanopuncture have also been used with variable success. This article reviews all currently accepted modalities and their effectiveness in the treatment of stretch marks. [ABSTRACT FROM AUTHOR]

Marc Bischoff received his PhD from the University of Lausanne, Institute of Police Science and Criminology, and later became the head of the Institute. His final examination paper for his doctorate degree constitutes a toolmark analysis and comparison between a suspected axe and questioned cuttings of wood trunks. Bischoff uses the scientific method to test the hypothesis he formulated. Dated 1916, this report includes his notes, measurements, photomicrographs of the questioned toolmarks and the test impressions, detailed sketches, technical discussion, results, and conclusions. Recognizing the historical value of Bischoff's work, it seemed important to get it translated. Photocopies of Bischoff's original work were obtained. The case report, translated from French, is presented here along with a brief history of the Firearm and Toolmark Identification field and Bischoff's role in the beginning of this field. Bischoff's work stands as testimony to the long tradition of the field of forensic toolmark analysis. [ABSTRACT FROM AUTHOR]

Striae are acquired atrophic lesions, due to tissue tension factors that cause elastic and collagen fibers to rupture, resulting in dermal connective tissue damage. It manifests with rosy tone and according to the evolution is characterized as rubra, later become chronic, atrophic and hypopigmented, called striations albas for lack of localized melanin production. The etiology is classified in mechanical, endocrine and infectious theories. Therapy is performed through the combination of cosmetological assets that aims to trigger the synthesis of collagen, elastin associated with microneedle techniques, which enhances the penetration of the dermal level of the active substance, the carboxytherapy that promotes the local vasodilation and the intradermotherapy that guarantees a high concentration of the drug. It is up to the biomedical Esteta to determine the asset and the therapeutics. Objectives: To describe the action of cosmetological assets combined with the intradermotherapy, carboxytherapy and microneedle techniques in the treatment of stretch marks. In addition to explaining the structure and function of the skin, to describe the striae, its incidence and location, to discuss the main theories of appearance of the striations and to classify them, to understand the techniques and the purpose of intradermotherapy, carboxitherapy and microagulation associated to the use of the cosmetological assets Vitamin C, Glycolic Acid Hyaluronic Acid and Organic Silicon.
