RESUMO
BACKGROUND: Striae distensae evaluation criteria have been recently described, but none is focused on objective striae assessment. With the purpose of better and objectively estimating the severity of striae distensae, the Objective Stretch Marks Assessment Scale has been developed by the authors' team. METHODS: Seven hundred White patients were included in the study and assessed. To assess the severity of striae distensae, abdomen, breasts, hips, gluteal area, back area, thighs, calves, and upper limbs photonumeric grading scales were developed. The Rasch model was used as part of the validation process. A score was attributed to each patient, based on the scales we developed. The interrater reliability and test-retest reliability were analyzed. RESULTS: Eight photonumeric scales for striae distensae treatment outcomes assessment were developed. All scales exceeded criteria for acceptability, reliability and validity. The interrater and intrarater reliabilities were good, with a substantial or virtually perfect interrater reliability for the total score (P = 0.16). CONCLUSIONS: The authors' results allowed them to validate the Objective Stretch Marks Assessment Scale as a reliable and reproducible tool to assess striae distensae treatment outcomes. This scale could be also considered as an important new metric that can be used in clinical research.

INTRODUCTION: Striae distensae (SD) appear clinically as parallel striae, lying perpendicular to the tension lines of the skin. SD evolve into two clinical phases, an initial inflammatory phase in which they are called "striae rubrae" (SR) and a chronic phase in which they are called striae albae (SA). Fibroblasts seem to play a key role in the pathogenesis of stretch marks. This study was aimed at describing and analyzing stretch marks-derived fibroblasts (SMF), the differences between SR- and SA-derived fibroblasts (SRF, SAF), testing two treatments in vitro (sodium ascorbate and PrP) on SAF. MATERIAL AND METHODS: To characterize the SMF, the expression of alpha smooth muscle actin (alpha SMA) was investigated. Type I collagen expression was measured in SAF, before and after adding different PrP concentrations and sodium ascorbate in the culture medium. Results were processed through statistical analysis models using the Student's t-test. RESULTS: A significant increase in alpha SMA (P <0.001) was observed in SRF. SAF treated with PrP and sodium ascorbate showed a resumption of their metabolic activity by an increase in collagen type I production and cell proliferation. After 24 h of incubation with PrP 1% and PrP 5% + sodium ascorbate, cell viability was increased by 140% and 151% and by 156 and 178% after 48 h, respectively, compared to the control. CONCLUSION: Our study shows that a biologically mediated improvement in SMF metabolic activity is possible. Our promising results require further trials to be able to confirm the reproducibility of this combined treatment, particularly in vivo. NO LEVEL ASSIGNED: This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.

OBJECTIVE: To investigate the predictive value of the Davey Score for striae gravidarum (SG) on the presence of pelvic adhesions at repeat cesarean delivery (CD). MATERIALS AND METHODS: The current study was a cross-sectional study conducted in a tertiary university hospital between November 2016 and March 2018. All women scheduled for elective CD were included if they had at least previous one CD with pregnancy in term fetus (37-40 weeks gestation. Preoperative evaluation of SG severity using Davey score, which is a validated scoring system, was done on the examination bed. Patients with no/mild striae (score 0-2) were classified as group (I) and women with severe striae (score 3-8) were classified as group (II). During surgery, pelvic adhesions were evaluated and classified according to the Nair's scoring system. The primary outcome was the difference in the rate of pelvic adhesions between both groups. RESULTS: The study included 300 women; group I included 114 women and group II included 186 women. About 90% of women with severe striae versus 82.5% of women with no/mild striae were found to have adhesions (p = 0.035). Dense adhesions were significantly present in severe striae group (57.4%) versus (41.5%) in no/mild striae group (p = 0.022). The mean Davey score in women in group (II) was significantly higher than group (I) (4.25 ± 3.36 vs. 3.09 ± 2.95, p = 0.03). Nair's score had a significant positive moderate correlation with Davey score (r = 0.541, p = 0.016). According to the results of multivariate regression analysis, Davey score >2 was the only variable associated with increased risk of pelvic adhesions (p = 0.010). CONCLUSION: Assessment of SG score in women with previous CD using Davey score might help to predict pelvic adhesions status before planning a new surgery.

OBJECTIVE: The aim of the study was to evaluate the effectiveness of carboxytherapy in the treatment of striae distensae. Additionally, discomfort and side effects associated with the treatment were assessed. MATERIALS AND METHODS: This study involved 15 women aged 22-40 years. They underwent 3 sessions of carboxytherapy at one-week intervals. Treatment was performed in skin area within stretch marks located on stomach, buttocks, and thighs. Cutometric probe was used to evaluate skin elasticity. Four measurements were performed-immediately before each treatment and one month after the last session. Photographic documentation was made before and after a series of treatment to perform clinical evaluation of changes in skin condition. RESULTS: Statistical analysis of results obtained with the use of Cutometer (R2 and R8 parameters) demonstrated that carboxytherapy significantly improved skin elasticity within stretch marks (P < .05). The analysis of photographic documentation revealed 58% improvement in stretch mark visibility. The width and length of stretch marks decreased, and their color became more like the natural color of the skin. Carboxytherapy is associated with moderate pain/discomfort. The occurrence of hematoma is the main side effect of this procedure. CONCLUSIONS: Carboxytherapy seems to be an effective method of reducing stretch marks. This procedure is safe, and it can be performed without the risk of complications. Moreover, it does not require special postoperative convalescence. Photographic documentation is a method of assessment of aesthetic procedures effectiveness, which is complementary to other objective methods (eg, the use of MPA probes).

BACKGROUND: Striae distensae (SD), a type of dermal scarring, are psychologically disappointing. To date, information and scientific research behind the role of hormonal factors in the development of SD are still unclear. It is vital to understand striae to offer patients the best therapeutic options. OBJECTIVES: To investigate early alterations regarding the expression of estrogen, androgen, and glucocorticoid receptors (estrogen receptor (ER), androgen receptor (AR), glucocorticoid receptor (GR) in skin samples of multigravida (MG) and nulligravida (NG) cases and to compare them with normal controls. METHODS: This study included 30 subjects (10 MG and 10 NG cases with early SD and 10 healthy controls). Biopsies from SD lesions, perilesional normal skin of cases and normal skin of controls were examined immunohistochemically for ER, AR, and GR expression using immune peroxidase technique. RESULTS: Comparing MG and NG with controls, ER expression appeared reduced in MG and NG (P-value<.001), AR was elevated in MG (P-value<.05) with no considerable difference in NG (P-value>.05), while GR was elevated in both MG and NG (P-value<.05). On comparing perilesional skin with SD lesions in each of MG and NG groups, SD lesions revealed reduced ER expression in both groups (P-value<.05), whereas in MG group: AR expression was elevated with no difference detected regarding GR (P-valueË.05); meanwhile in NG, elevated expression in both AR and GR expression was noted (P-Value<.001) CONCLUSIONS: Striae distansae lesions demonstrated a significant increase in the expression of AR and GR and a declined expression of ER indicating their involvement in the development of early SD.
