V-EMF therapy: A new painless and completely non-invasive treatment for striae gravidarum.

BACKGROUND: The appearance of striae gravidarum (SG) during pregnancy is a common problem. The most common SG are abdominal striae, which can cause the greatest sequelae after pregnancy, and in the long term. There are several solutions to prevent and treat these striae, but not all are completely effective, and not without side effects. AIMS: The aim of this study was to evaluate the effectiveness of a treatment that applies an electromagnetic field under vacuum (V-EMF therapy) on the abdominal SG. METHODS: A retrospective analysis was conducted on the medical records of 26 women affected by abdominal SG and treated with V-EMF therapy. The results were evaluated using two different 5-point Likert Scales: one administered to the treated subjects to evaluate their satisfaction, and one to the doctors who performed the treatment, to evaluate the improvement of the striae. The presence of side effects, and the effects of sun exposure after treatment were also considered. RESULTS: Only two treated subjects rated their level of satisfaction with a Score III on the Liker Scale. Everyone else expressed higher levels of satisfaction. Only one doctor rated the improvement of the striae with a Liker scale score of III. All the others reported greater improvements. No discomfort or side effects were noted either during the individual treatment sessions, or at the end of the treatment. The striae showed a newfound ability to tan. CONCLUSIONS: V-EMF therapy proves to be a valid, safe, and effective treatment modality for SG.

Striae gravidarum treatment: evaluating non-ablating fractional laser (NAFL) efficacy and safety.

BACKGROUND: Striae gravidarum (SG) is a common pregnancy-related dermatologic problem, for which finding an effective treatment remains a challenge. AIM: To evaluate the safety and efficacy of 1540 nm non-ablative fractional laser (Star lux 500) in the treatment of SG in Iranian women and peruse the relationship between clinical improvement rate and patient characteristics as well as clinical features of striae. METHOD: A prospective before-after study was conducted on 50 patients with SG who received three monthly sessions of 1540 nm non-ablative fractional laser and were followed for 2 months after the last treatment session. Clinical changes were measured using both provider-rated outcome through before/after pictures represented by final clinical score (from 0 to 5) and patient-reported outcome (patient global assessment or PGA). RESULTS: Over the course of the study both final clinical score and PGA increased significantly from week 4 to week 20 (P value: <0.001 and 0.048, respectively). Only modest adverse effects including erythema, edema and hyperpigmentation were noted. CONCLUSION: In conclusion, patients with SG of different type (rubra/alba) or maturity may somehow benefit from treatment with NAFL experiencing minimal transient side effects.Therefore, NAFL may be considered a safe and partially effective treatment option for stretch mark of patients with SG.

Risk factors of striae gravidarum and chloasma melasma and their effects on quality of life.

OBJECTIVE: This study aims to determine the risk factors associated with striae gravidarum (SG) and chloasma melasma (CM) and their effects on the quality of life. METHODS: This descriptive and cross-sectional study was carried out in Turkey with 1000 pregnant women at 36 weeks of gestation and above. Personal information form, Quality of Life (SF36) Scale, Skindex-29 Scale, and MelasQoL-TR questionnaire were applied to pregnant women. Besides, skin types of pregnant women were determined using Fitzpatrick Skin Type Classification. Davey's score was used to determine the severity of SG. RESULTS: In the study, the prevalence of SG was found as 67.9% (n = 679), and the prevalence of CM 23.5% (n = 235). There was a significant relationship between young age, low education level, high BMI before pregnancy, history of SG in her previous pregnancy, family history of SG, and development of SG in pregnant women (p = 0.001). There was a significant relationship between CM in her previous pregnancy and family history of CM and development of CM (p = 0.001). The quality of life of pregnant women with SG was found to be lower than without SG (p < 0.001). The quality of life of pregnant women with CM was found to be lower than without CM (p < 0.001). CONCLUSIONS: As a result, in the study, it was determined that young age, low education level, high BMI, history of SG in previous pregnancy, and family history of SG were risk factors for SG. The risk factors of CM, on the other hand, were found as the history of CM in the previous pregnancy and the family. It was identified that SG and CM have adverse effects on the quality of life.

Bullous striae distensae in a young patient with cardiomyopathy.

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.

Efficacy of Combined Treatment with Intense Pulsed Light and Erbium Fractional Laser in Striae Gravidarum.

Purpose: Laser and intense pulsed light (IPL) treatments are preferred over invasive procedures due to less pain. This study looked at the efficacy and safety of IPL and Erbium fractional laser for patients with striae gravidarum (SG). Patients and Methods: All 60 patients with SG were successfully enrolled in the study. IPL treatment was followed by Erbium fractional laser (wavelength 2940 nm) treatment at 4-week intervals for a total of three treatments. SG elasticity was assessed with a SEM575 custom instrument and patients were scored for SG span with an Antera 3D multifunctional skin imaging analyzer. A 3D skin impact system was used to assess patients' epidermal thickness. A visual analog scale (VAS) was used to assess patients' pain scores during the treatment period. Improvement in stretch marks was assessed with the Global Aesthetic Improvement Scale (GAIS). The occurrence of adverse events was recorded at a follow-up of 3 months. Patient satisfaction with the outcome of the treatment was also recorded. Results: Area of stretch marks decreased from 7.89 ± 0.49 cm2 pre-treatment to 4.94 ± 1.16 cm2 post-treatment (P < 0.001). The grayness values and atrophy of stretch marks were reduced after treatment. Furthermore, skin elasticity and thickness at the lesions of patients increased significantly after the treatment (P < 0.001), while the width of the stretch marks significantly decreased (P < 0.001). The VAS score was 5.45 ± 1.31, the incidence of adverse events was 25%, and patient satisfaction with the efficacy was 96.67%. Conclusion: IPL combined with Erbium fractional laser improves the area and atrophy of SG, lightens the color, and increases the elasticity and thickness of the skin, with high treatment safety and remarkable clinical results.

New Progress in Therapeutic Modalities of Striae Distensae.

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.

Prediction of Intraperitoneal Adhesions in Repeated Cesarean Section Using Sliding Sign, Striae Gravidarum, and Cesarean Scar.

Background: Intraabdominal adhesions are associated with an increase in complications during cesarean section because of recurrent cesarean sections. This is why the possibility of predicting adhesions is important. In this study, the diagnostic value of depressed scar, severe striae gravidarum, and negative sliding sign, and their combinations were evaluated for predicting intraabdominal adhesions of cesarean candidates. Methods: This prospective descriptive study was performed during 2019-2020 on 123 pregnant women referred to Ayatollah Taleghani university hospital with a gestational age of ≥36 weeks 0 days who were candidates for cesarean section because of a previous cesarean section. In each patient, the presence of a depressed scar, a severe striae gravidarum, the absence of a sliding sign, and the presence and severity of adhesions during the operation were examined. Sensitivity and specificity, and positive and negative predictive values of each of the 3 indicators and their combinations were calculated. Results: The frequency distribution of severe adhesion in these individuals was 16.27%. The highest sensitivity was related to depressed scar and negative sliding sign (65%). The highest specificity was related to the negative sliding sign and its combinations (97%-99%). The highest positive predictive value was related to negative sign sliding and its combinations (81%-92%). The negative predictive values of depressed scar, negative sliding sign, and severe striae gravidarum, and even their combinations were almost the same and approximately between 89% and 93%. Conclusion: To predict the presence of adhesions in a cesarean candidate because of a previous cesarean section, you should first examine the striae gravidarum and scar. In the absence of a depressed scar and severe striae gravidarum, there is a 90% chance of no adhesions. According to this study, if both signs are present, it is recommended to check the sliding sign to obtain a more accurate estimate.

Association between striae gravidarum and pelvic floor dysfunction symptoms during pregnancy.

INTRODUCTION AND HYPOTHESIS: Striae gravidarum are linear atrophic scars appearing on the abdomen of pregnant women reported to be related to pregnancy-induced changes in the connective tissue. Pelvic floor distress symptoms are also known to be linked to connective tissue weakness. Given that common pathophysiological pathways may play a role in both striae gravidarum and pelvic floor dysfunction symptoms, we sought to examine whether there is a correlation between them during pregnancy. METHODS: A prospective observational study among third-trimester pregnant women who visited a tertiary medical center for routine pregnancy follow-up was conducted by using the Pelvic Floor Distress Inventory (PFDI-20) questionnaire to evaluate pelvic floor distress symptoms and the Davey method for evaluating striae gravidarum severity. Obstetrical characteristics as well as pelvic floor distress symptoms were compared between two groups according to the severity of striae gravidarum. Univariate analysis was carried out using appropriate tests; PFDI scores were compared between the groups using the Mann-Whitney test. RESULTS: Women with striae gravidarum were significantly older (31.06 vs. 28.83 years, p < 0.01), had a lower body mass index (27.5 vs. 30.98, p < 0.01), and gave birth to smaller neonates (3155 vs. 3389 g, p < 0.01). In addition, the overall and median PFDI-20 scores differed between the groups (with severe SG having the highest median score of 20 and those with milder SG having a score of 16 compared to 14 in those without SG). A distinct association between the PFDI-20 score and SG severity was not demonstrated (p = 0.63). CONCLUSIONS: In our population, an association was demonstrated between pelvic floor distress symptoms and the presence of striae gravidarum. However, following a linear regression model, no statistically significant association between SG severity and total PFD-20 score was seen. Our findings strengthen the hypothesis of common connective tissue involvement in the pathophysiology of both conditions.

Is striae gravidarum a sign of spontaneous premature birth?

BACKGROUND: This study aimed to investigate the association of striae gravidarum (SG) and preterm delivery. MATERIAL AND METHODS: This prospective cross-sectional study was performed between November 2018 and February 2019. In addition to demographic variables, SG score of the abdomen, presence of striae on breasts, arms, hips, and thighs were recorded. Davey's scoring system was used to define the severity of SG in the abdomen by the same investigators. Patients with cervical dilatation of 6 cm or more were included in the preterm labor group. RESULTS: A total of 292 women were included in the study. Of these, 176 (60.3%) had no SG, 20 (6.8%) had mild SG, and 96 (32.9%) had severe SG. Davey's score was lower in the group of patients with preterm birth than in the term birth groups (p = .002). SG in the breasts was more common in the preterm labor group than in the term birth group (p = .007). Also, the presence of SG in the legs was less common in the preterm labor group than in the term birth group (p < .001). In a logistic regression model, stria in the breasts revealed most significant in preterm delivery. CONCLUSIONS: No difference was found in the pregnancy length in gestational weeks among groups of different SG severity. The Davey's score and the presence of striae in the legs and breasts were found different between the preterm and term birth groups, and the term birth subgroups.

Striae gravidarum and different modalities of therapy: a review and update.

The term striae gravidarum (SG) refers to a kind of striae distensae (SD) that develops particularly during pregnancy. According to the level of maturity of the lesions, SG is divided into striae rubra (SR) and striae alba (SA). The pathogenesis remains unclear; recent studies have implicated abnormalities in elastic fibers, collagen fibrils, and other extracellular matrix (ECM) components. Changes in the expression of hormone receptors and hormone levels have also been hypothesized. Considering this new information, we reviewed successful treatments of SG and listed them in two tables. Our review found that topical treatments were relatively weak compared with laser and light treatment, with which the appearance of SR and SA can be significantly improved. Lasers combined with other modalities, such as additional energy devices and topical agents, were also proven effective, but more large-scale trials are necessary.

Prevalence and risk factors of striae gravidarum in a cohort of multiracial postpartum Nepalese population.

BACKGROUND: Striae gravidarum (SG), popularly called as stretch marks, is a common pregnancy-related asymptomatic skin condition, but is a cosmetic concern for females. A few epidemiological studies have been reported from Asian countries. However, no such study has been done in Nepal. AIMS: This study was aimed to know the prevalence and risk factors associated with SG in a cohort of multi-ethnic postpartum Nepalese women who had delivered after completion of 36 weeks. PATIENTS/METHOD: A cross-sectional comparative study was conducted among 420 postpartum females who had delivered after completion of 36 weeks of gestation. Data were collected in the form of a questionnaire and relevant physical examination was done. The severity of SG was assessed by using Davey's scoring. RESULT: Out of 420 females, 260 (62%) had SG while 160 (38%) did not. According to the results of logistic regression analysis, young age (<25 years), large abdominal circumference (>100 cm), increased weight gain during pregnancy (>15 kg), presence of family history of SG, gestational diabetes mellitus, altered bowel movement, and presence of striae on the breasts, thighs, and buttocks were found to be independent risk factors for SG. CONCLUSIONS: Future expectant mothers must be informed about the risk factors of SG development. They need to be made aware that SG can be prevented by considering the modifiable risk factors, such as excessive weight gain. They should also be informed that SG is permanent and currently there is no definite treatment.

Efficacy of 2 940 nm Er∶YAG laser combined with electronic injection of collagen in treatment of striae gravidarum / 中华医学美学美容杂志

Objective:To assess the efficacy and security of 2 940 nm Er∶YAG laser combined with electronic injection of collagen in treatment of striae gravidarum.Methods:The symmetrical spots on both sides of abdomen of 21 subjects with striae gravidarum were divided into treatment and control groups by simple randomization method in the Department of Burn and Plastic Surgery, 903 Hospital from November 2017 to May 2019. The treatment group were treated with 2 940 nm Er∶YAG laser combined with electronic injection of collagen every 2 months for 3 sessions, and control group were received 2 940 nm Er∶YAG laser combined with electronic injection of physiological saline. The total effective rate, satisfaction, striae width, histopathology, and the adverse reaction were evaluated at 6 months after treatment.Results:A total of 19 subjects completed the whole trail. The clinical effective rate of the treatment group was 89.47% and the control group was 68.42%. In the treatment group, 11 cases were satisfied with and 6 cases were very satisfied with treatment outcome. In the treatment group, 8 cases were satisfied with and 3 cases were very satisfied with treatment outcome. The difference of total effective rate and satisfaction was statistically significant ( χ2 was 3.91 and 5.54, P was 0.045 and 0.019). The maximum width decreased by (1.53±0.97) mm on treatment side, and (1.37±1.01) mm on control side. The difference of striae width was statistically significant. No adverse effect was observed on both sides. Conclusions:The combination of the 2 940 nm Er∶YAG laser with electronic injection of collagen for treatment of striae gravidarum is a safe and effective approach for improving of striae gravidarum.

Perception of Stretch Marks Risk Factors Among Adults in Riyadh, Saudi Arabia.

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.

Study on the methodology of striae gravidarum severity evaluation.

BACKGROUND: Striae gravidarum is a common occurrence in pregnancy and many women expect to prevent its development. At present, laser treatment has been used to improve the appearance of striae gravidarum, but the choice of laser type, treatment time, and frequency depend on the therapeutic effect. How to obtain an effective evaluation of striae gravidarum during and after treatment is very important. However, there is no unified evaluation parameter about striae gravidarum. In this paper, we studied the methodology evaluation of striae gravidarum severity. First, the laser therapeutic apparatus was selected as the experimental equipment and different striae gravidarum photos during treatment were obtained. Second, the subject evaluation parameters were chosen based on the literature research and the dermatologists' guidance. Then, the striae gravidarum photos were divided into different groups by dermatologists based on these parameters. Finally, the objective detection parameters were designed based on the photos feature and subject evaluation parameters. Then, the objective detection parameters were used as the input of the support vector machine and the evaluation results were compared. RESULTS: Based on the subject evaluation parameters, the experimental data could be divided into mild, moderate and severe groups. The experiment results showed that the striae gravidarum severity of two randomly patients were improved before and after treatment, which verified the validity of the parameters. In addition, the chosen objective detection parameters were different among different groups. With all the objective parameters as the support vector machine input, we could achieve the best recognition rate (82.71%) in the striae gravidarum severity classification. The four parameters (color difference, average density, average width, distribution area) calculated from the photos as the input could achieve acceptable accuracy (81.69%). CONCLUSIONS: The subject evaluation parameters and objective detection parameters proposed in this paper can be used to evaluate the striae gravidarum severity, which is of great significance for the construction of auxiliary diagnostic instrument for striae gravidarum treatment.

Comparative study of treatment for striae alba stage striae gravidarum: 1565-nm non-ablative fractional laser versus fractional microneedle radiofrequency.

Striae gravidarum is a common dermatologic condition for females caused by multiple factors during pregnancy. It remains a therapeutic challenge especially in the striae alba (SA) stage, generating psychological and emotional distress to those affected. This study aims to compare the efficacy and safety of 1565-nm non-ablative fractional laser (NAFL) and fractional microneedle radiofrequency (MRF) for treatment of SA striae gravidarum. Fourteen Chinese women with SA striae gravidarum were included in this study. Patient abdomens were randomly divided into NAFL and MRF treatment sides, treated three times at 6-week intervals. Treatment efficacy was evaluated by subjective (clinical assessments, patient satisfaction rating, adverse effects assessment) assessments and objective (skin melanin index measurement, histological study) assessments. Clinical assessment suggested MRF was more effective (P = 0.0143) for improving the appearance of SA striae gravidarum. Both NAFL and MRF demonstrated effective improvement (P = 0.0082 and P = 0.0158, respectively), with no significant difference according to patient satisfaction ratings and changes in melanin index (P = 0.5900). Both treatments induced limited adverse reactions, but MRF treatment caused significant pain compared with the more moderate NAFL treatment (P = 0.0003). MRF treatment increased neocollagen and elastic fibers more significantly than NAFL, based on histological assessments (P = 0.0298 and P = 0.0048, respectively). MRF treatment improved collagen regeneration in SA striae gravidarum more than NAFL but caused considerable pain during treatment. Corresponding treatment or therapeutic strategies should be applied according to clinical scenario.

Negative perceptions and emotional impact of striae gravidarum among pregnant women.

BACKGROUND: The impact of striae gravidarum (SG), or stretch marks of pregnancy, on quality of life (QoL) is unclear. OBJECTIVE: The purpose of this study was to investigate how SG affect QoL in pregnant women. METHODS: In this cross-sectional survey study of healthy pregnant women who developed SG during their current pregnancy, we asked about the impact of lesions on emotional, psychological, and life-quality facets. Spearman product-moment correlation coefficients were generated to determine the strength of relationships between variables. RESULTS: We analyzed 116 valid surveys. Participants reported permanency of SG as the top physical concern (n = 87; 75%). With regard to severity, nearly three-quarters of participants rated their lesions as very prominent (n = 24; 21%) or moderate (n = 57; 49%). Among the life-quality facets queried, embarrassment/self-consciousness was the most frequently associated with SG, with over one-third of participants reporting "a lot" (n = 19; 16%) or a "moderate" (n = 26; 22%) amount of embarrassment/self-consciousness related to having SG. Lesion severity significantly correlated with the degree of embarrassment/self-consciousness (r = .543), as well as the impact of SG on other life-quality facets, including overall QoL (r = .428), clothing choice (r = .423), self-image/self-esteem (r = .417), feelings of anxiety/depression (r = .415), and social activities (r = .313; all p ≤ .001). Nearly one-quarter of participants believed that emotional distress related to SG was similar or greater than that caused by other skin problems, such as acne, psoriasis, or eczema. CONCLUSION: SG can be associated with a host of negative reactions reflecting increased psychological and emotional distress, including embarrassment and decreased QoL. These consequences may compound the emotional stress of pregnancy, potentially warranting psychological support and adjustment strategies.

Association between serum 25-hydroxyvitamin D levels and the presence and severity of striae gravidarum in primigravid women.

BACKGROUND: Striae gravidarum (SG) are a form of scarring on the skin observed during pregnancy and an important cosmetic problem. Vitamin D plays an important role in the skin. AIMS: To assess the association between serum 25-hydroxyvitamin D (25(OH)D) levels and the presence and severity of SG in primigravid women. METHODS: The study included 91 primigravid women at the gestational age of 36-41 weeks. Patients were examined and divided into two groups with respect to whether they had SG or not. Striae were scored using the numerical scoring system of Atwal et al. The serum 25(OH)D levels were evaluated. RESULTS: While 55 patients (60.5%) had SG, 36 (39.5%) did not. The mean serum 25(OH)D level of women with SG was 17.69 ± 9.81 ng/mL and of women without SG was 21.18 ± 11.71 ng/mL. There was no statistically significant difference between two groups (P = .144). Multivariate logistic regression analysis has shown that women who have normal values of serum 25(OH)D (≥30 ng/mL) have a lower risk of having SG than women who have scarce levels of serum 25(OH)D (<20 ng/mL) after adjusting for confounding factors (adjusted odds ratio = 0.18, 95% confidence interval: 0.04-0.72, P = .015). According to the results of the linear-by-linear test, the association between serum 25(OH)D levels and the severity of SG was not found significant (P = .82). CONCLUSIONS: This is the first study to show that having normal values of serum 25(OH)D is linked to a lower risk of having SG than scarce levels. Therefore, management of vitamin D deficiency might help prevent SG in primigravid women.

A qualitative study of the factors influencing recruitment to a pilot trial on the prevention of striae gravidarum.

BACKGROUND: Striae gravidarum are a common occurrence in pregnancy and many women use a topical product to prevent their development or lessen their appearance if they do develop. There is a lack of evidence on the effectiveness of many of the products used by women. This study arose from challenges in recruitment to a pilot randomised trial (ISRCTN trial registration number:76992326) designed to evaluate the feasibility of a definitive trial to compare a moisturising oil to no treatment in the prevention and reduction in severity of striae gravidarum. The study reported here explored the factors influencing recruitment to that pilot trial. METHODS: A qualitative descriptive study was undertaken involving primigravid women attending an Irish maternity hospital. Data were collected by semi-structured telephone interviews over a four-week period and analysed using the framework method of analysis. Fifteen interview transcripts were included in the analysis. RESULTS: Four main themes consisting of twelve categories were identified from the interview data. The themes focused on women's prevention of stretch marks and their choice of anti-stretch mark product, who and what influenced that choice and influences on trial participation. In relation to influences on trial participation, the possibility of being randomised to the non- intervention or control group was a deterrent for many women. CONCLUSIONS: The prevention of stretch marks is important to pregnant women, as is their choice of product to prevent them. Offering women the opportunity to be part of a trial that would be of low burden and would test a well-known product may optimise recruitment. However, reluctance to be randomised because of the possibility of being allocated to the non-intervention control group suggests that further work is needed in this field on how best to communicate uncertainty to potential participants.

Investigation of coenzyme Q10 levels and predisposing factors in patients with striae gravidarum.

BACKGROUND: Striae gravidarum (SG) can cause pregnant women severe psychological stress. OBJECTIVE: This study aimed to compare primigravidas with and without SG concerning fasting blood coenzyme Q10 (CoQ10), age, skin type, family history, gestational weight gain, pre- and post-pregnancy BMI, daily water consumption during pregnancy, gender and weight of baby, and the educational level. METHODS: The study included 79 primigravidas in the gestational week of 36 or above. The patients were divided into two groups based on the presence of SG. The fasting blood CoQ10 levels and other associated parameters were compared between the groups. RESULTS: Of the 79 primigravidas, 35 (44.3%) had SG. There was no statistically significant relationship between striae and CoQ10 (P = 0.144 and P = 0.189, respectively). Predisposing factors for striae were young pregnancy, light skin color, family history, high pre- and post-pregnancy BMI, increased gestational weight gain, and increased newborn weight. There was no significant relationship between striae development and educational level or water consumption during pregnancy. CONCLUSION: This is the first study to show that CoQ10 did not significantly differ between women with and without SG. Further studies with a larger case series are needed to elucidate predisposing factors for striae and involvement of CoQ10 in this condition.

Prediction of pelvic adhesions at repeat cesarean delivery through assessment of striae gravidarum score: A cross-sectional study.

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.
