Unveiling the Uncommon: A Case Series on Cushing's Disease During Pregnancy.

Cushing's disease (CD) is characterized by a high rate of hypogonadism and infertility. It is difficult to detect CD in pregnant women who present with symptoms such as weight gain, striae, headache, backache, and pedal edema that overlap with the physiological changes of pregnancy. In this paper, we present three cases of CD likely missed during pregnancy and later also discuss the approach to diagnosis and management of CD in pregnancy.

Clinical Characteristics, Identification, and Treatment of Lichen Planus: A Case Report.

Women are primarily affected by lichen planus, a chronic autoimmune skin and mucosal disorder in their 40s to 60s. Medication, systemic disorders, and mental stress are some of the factors that can cause it, though the precise cause is still unknown. Middle-aged females are the main victims of the disease; children are rarely affected. Oral lichen planus (OLP) is less common in atrophic and erosive forms. There is disagreement over whether OLP causes cancer; therefore physicians need to keep a close watch for any intraoral lichenoid lesions, and patients with OLP are advised to follow up regularly. This case report details a 52-year-old woman's right buccal mucosa and tongue affected by reticular lichen planus.

Efficacy of green tea ( Camellia sinensis Linn) 3% extract cream on improvement of striae distensae.

Background: Striae distensae (SD) is a skin condition that frequently causes dermatological consultations and although asymptomatic, it may can cause itch and burning sensation. Green tea extract contains polyphenol, including flavanol, flavandiol, flavonoid, phenolic acid, amino acids and minerals which play a role in the repair of stretch marks through anti-inflammatory mechanism, increase collagen production, fibroblast proliferation, and skin hydration. Objective: To determine the efficacy of green tea extract cream on striae distensae. Methods: This is a pre-experimental clinical trial with a pretest-posttest design on 36 subjects with striae distensae. Diagnosis establishes through history taking and clinical evaluation. Imam Nelva Alviera (INA) score was used as SD severity before and after the application of the 3% green tea extract cream carried out at weeks 0, 2, 4, 6, and 8. Side effects and subjects' satisfaction were also recorded. Cochran test was carried out to see the difference before and after treatment, with a p-value <0.05 considered significant. Results: Majority of study subjects were 18-25 years (77.8%), had history of pregnancy (75%), had a history of menarche at the age of 12 years (27.8%) and all subjects had striae alba. There was significant decrement in INA score for striae distensae (p<0.001) after eight weeks administration of 3% green tea extract cream. Clinical improvement and no side effects were also noted. All subjects were satisfied. Conclusions: The use of 3% green tea extract cream can improve the appearance of SD.

Association Between Striae and Pelvic Organ Prolapse in Women: A Systematic Review and Meta-Analysis.

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.

Photobiomodulation versus fractional carbon dioxide laser for stria alba in phototype III-IV: a randomized controlled study.

Striae distensae are common dermatological complaint. Cold laser using low-level light/laser therapy (LLLT) offers healing and analgesic effects and was not yet compared to 'hot lasers' efficacy. Study objective: to assess the efficacy and safety of LLLT in the management of stria alba compared to fractional carbon dioxide (FCO2) laser alone and to the combined use of both devices. Thirty patients with stria alba were randomized to receive either LLLT using diode 808 nm; 8-12 sessions, 2-3 sessions weekly (Group A) or FCO2 laser; 2 monthly sessions (Group B) or combined both devices simultaneously (Group C). Follow up was at 1 month and 3 months after last session. The efficacy of LLLT was statistically comparable to FCO2, despite numerical superiority of the latter. The combined group had the least numerical values in all efficacy outcomes. Patients in LLLT group did not experience any downtime. LLLT is effective in the management of stria alba comparable to the FCO2 laser. The lack of downtime with LLLT is reflected positively on patient's satisfaction. However, this is counterbalanced by the frequent weekly visits. Although adding LLLT to FCO2 laser palliates the laser side effects but it offers the least efficacy. Trial registration number NCT04165226 (clinicaltrials.gov).

Effective improvement methods for striae distensae: A novel approach utilizing laser-induced micro-jet injectors with poly-d,l-lactic acid.

INTRODUCTION: Striae distensae (SD), or stretch marks, result from rapid stretching of the skin due to various factors. Conventional treatments often yield unsatisfactory results, leading to the exploration of alternative methods. Laser-induced microjet technology offers a promising approach for drug delivery to target areas. This study investigates the efficacy of using a microjet injector with poly-d,l-lactic acid for treating SD. METHODS: Four female participants with SD were treated with poly-d,l-lactic acid solution using a microjet injector over five sessions. Patients were assessed based on severity scales before and after treatment. Topical anesthetics were applied to minimize discomfort. Injection techniques were optimized to reduce side effects such as bleeding and pain. RESULTS: All patients showed significant improvement in SD appearance after 5-7 treatments. Assessment scales indicated positive outcomes both immediately after treatment and at the 32-week follow-up. Minimal side effects, primarily petechiae, were observed. DISCUSSION: Laser-induced microjet technology offers several advantages, including rapid drug delivery and mechanotransduction effects, promoting skin regeneration. Poly-d,l-lactic acid injections demonstrated effectiveness in treating SD, particularly when delivered via microjet injectors. Patients expressed high satisfaction due to the procedure's minimal invasiveness and quick recovery. CONCLUSION: Utilizing a needleless microjet injector with poly-d,l-lactic acid shows promise as a treatment for SD, typically requiring 5-7 sessions for optimal results. Mild petechiae may occur as a common side effect. This approach offers an effective and minimally invasive alternative for addressing this common cosmetic concern.

Low Molecular Weight Hyaluronic Acid Added to Six Specific Amino Acids in the Treatment of Striae Alba (SA): An Observational Study.

Striae distensae or stretch marks are a common complaint among women and can be distressing. The present study aimed to assess the efficacy of a mixture of low molecular weight hyaluronic acid and six amino acids when applied with a specific intradermal injection technique known as intra-mural fluid technique. A clinical study was carried out in 32 patients (with a dropout rate by 9.4%) with striae distensae alba (SA) in one or more of the following anatomical areas: breast, abdomen, inner thigh, trochanteric area, gluteal area, posterior supra-iliac area, and lumbar area. Product efficacy was assessed by the investigator using the Global Aesthetic Improvement Scale, while a Likert scale was used to evaluate to score the treatment tolerability and a QoL stretch marks questionnaire was used to investigate the patients' self-body image. The treatment was effective in improving the appearance of SA fifteen days after the second treatment and 6 months after the first treatment (and after a total of 4 treatments). The product efficacy and tolerability were also perceived by the patients during each treatment session. Our results suggest that the test treatment is a valid treatment option to decrease the appearance of SA.

Bullous striae distensae in a nephrotic syndrome patient: First case report from the Middle East of a rare presentation and review of the literature.

Striae distensae is a common cutaneous phenomenon that begins as reddish linear atrophic plaques (striae rubra) that over time progress to silvery-white coloration (stria alba). Striae distensae in rare occasions becomes edematous, ulcerative, emphysematous, or urticated. Bullous striae distensae is a sequela of conditions causing interstitial edema along with systemic glucocorticoids use. To our knowledge, only eight cases of bullous striae distensae have been reported in the literature. Herein, we report a 17-year-old female, known case of nephrotic syndrome, presented to our clinic with abdominal fluid-fill cutaneous lesions only for 5 days. She had used systemic glucocorticoids for more than a decade before she was labeled as steroid resistant nephrotic syndrome. Cushingoid body habitus were observed during physical examination, in addition to translucent bullae overlying her previously known stretch marks. Punch biopsy of the lesions revealed dermal edema with thinned collagen bundles. Based on these clinicopathological findings, a diagnosis of bullous striae distensae was made. Awareness of this rare complication and unusual clinical presentation is fundamental to avoid unnecessary and excessive interventions whether investigatory or therapeutic in order to provide appropriate management of the underlying condition.

Microneedling Therapy for Striae Distensae: Systematic Review and Meta-Analysis.

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.

The role of the beautician in reducing striae.

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.

Evaluation of the efficacy of mesenchymal stem cells derived conditioned medium in the treatment of striae distensae: a double blind randomized clinical trial.

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.

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.

Efficacy and Safety of an Autologous Micrografting Procedure for Management of Striae Distensae in Women.

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.

Efficacy and safety of bipolar fractional radiofrequency vs. 2940-nm Er:YAG ablative fractional laser in striae distensae treatment: A split abdomen study.

BACKGROUND: Striae distensae (SD) is a challenging cosmetic condition. Ablative fractional laser (AFL) is an effective method for treating SD. Recently, fractional radiofrequency (FRF) has been shown to be a promising treatment for SD; however, few studies have shown the differences between FRF and AFL in the treatment of SD. AIMS: This study aimed to evaluate and compare the clinical efficacy and safety of bipolar FRF with 2940-nm erbium yttrium aluminum garnet (Er:YAG) AFL in the treatment of SD. PATIENTS/METHODS: Twenty volunteers with abdominal SD were enrolled in this study. One half of the abdomen was treated with 2940-nm Er:YAG AFL, whereas the other half was treated with bipolar FRF, with three sessions at 4-week intervals. Photographic evaluations of clinical improvement were conducted by two independent investigators before and after treatment, and the patients provided self-assessments. Two participants underwent three punch biopsies, one before treatment and two obtained from bilateral representative skin lesions on the abdomen 3 months following the final treatment. RESULTS: Clinical improvements were observed in SD on both sides of the abdomen after the two treatments. Post-treatment skin biopsies revealed increased thickness in the epidermis and dermis, and higher collagen and elastin density compared to those at the baseline. No statistically significant differences were observed in the clinical outcomes between the two treatment approaches. CONCLUSIONS: The efficacy and safety of bipolar FRF treatment are comparable to those of 2940-nm Er:YAG AFL treatment, providing an alternative and effective treatment for SD.

A new freshwater species of Pinnularia (Bacillariophyta) from Hunan Province, China.

This study describes a new species of Pinnularia, P.hupingensissp. nov., on the basis of light and scanning electron microscope images. Pinnulariahupingensissp. nov. is characterised by its linear valve outline, extremely divergent striae, and very large hexagonal central area occupying ca. 1/5-1/8 of the valve length. The primary and secondary sides of the valve and the internal proximal raphe fissures are discussed. The new species is compared to similar taxa of the genus Pinnularia.

Clinical efficacy of stromal vascular fraction gel in the treatment of mature striae distensae.

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.

The olfactory striae: A historical perspective on the inconsistent anatomy of the bulbar projections.

Central olfactory pathways (i.e., projection axons of the mitral and tufted cells), and especially olfactory striae, lack common terminology. This is due to their high degree of intra- and interindividual variability, which has been studied in detail over the past century by Beccari, Mutel, Klass, Erhart, and more recently, by Duque Parra et al. These variations led to some confusion about their number and anatomical arrangement. Recent advances in fiber tractography have enabled the precise in vivo visualization of human olfactory striae and the study of their projections. However, these studies require their algorithms to be set up according to the presumed anatomy of the analyzed fibers. A more precise definition of the olfactory striae is therefore needed, not only to allow a better analysis of the results but also to ensure the quality of the data obtained. By studying the various published works on the central olfactory pathways from the first systematic description by Soemmerring to the present, I have traced the different discussions on the olfactory tracts and summarized them here. This review adopts a systematic approach by addressing each stria individually and tracing the historical background of what was known about it in the past, compared to the current knowledge. The chronological and organized approach used provides a better understanding of the anatomy of these essential structures of the olfactory system.

Wickham striae on skin appendages: a helpful dermoscopic feature.

Lichen planus (LP) is a chronic inflammatory disease, clinically characterized by purpuric, itchy papules that typically spread on the trunk and extremities. Other body sites can also be affected, including mucosal membranes, nails, and the scalp. The use of dermoscopy is essential in determining the diagnosis of LP, as it may highlight pathognomonic features such as Wickham striae (WS). WS are thin, pearly white structures arranged in a reticular pattern that is observed over LP lesions and histologically correspond to epidermal hypergranulosis. WS is usually most visible on the oral mucosa but can also cover almost every active LP papule. Here, we report two cases of biopsy-proven LP that show WS on dermoscopy in two specific sites: the scalp and proximal nail fold.

Review of radiofrequency microneedling: history, devices and uses.

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.
