ABSTRACT
INTRODUCTION: Due to the increasing prevalence of immune-mediated diseases such as psoriasis, lichen planus, rheumatoid arthritis and inflammatory bowel disease, dermatologists have turned to new biologic drugs known as DMARDs (disease-modifying anti-rheumatic drugs) in recent years. AREAS COVERED: In this study, we evaluate the immune-mediated dermatological side effects of DMARDS by reviewing and analyzing previous peer-reviewed research on the effects of TNF-α inhibitors in the treatment of skin diseases, as well as adverse effects of these drugs and some of the main causes of these effects. EXPERT OPINION: DMARDs are very effective in improving control of the above diseases. TNF-α inhibitors are an important group of DMARDs that are widely used. The paradoxical adverse events (PAEs) associated with the use of TNF-α inhibitors are divided into three categories: true paradoxical, borderline paradoxical, and non-paradoxical. True PAEs include conditions for which TNF-α inhibitors are approved for treatment. Borderline PAEs are considered to occur with this class of drugs for which there is no definite approval but for which there is sufficient evidence. Although these events are rare, early recognition of the accused drug and appropriate decision-making may prevent progression of complications and irreversible side effects.

BACKGROUND: Stromal vascular fraction (SVF) cells derived from adipose tissue and platelet-rich plasma (PRP) are among novel treatments for androgenetic alopecia (AGA). We aimed to investigate the effect of adding SVF to PRP and compare it to administering PRP injection alone. METHODS: Eighteen patients were randomly divided into two groups of nine. The PRP group was treated with PRP at all three visits at 1-month intervals, while the SVF-PRP group received an SVF injection on the first visit and a PRP injection on the second and third visits. Each group was evaluated at baseline and 20 weeks after the therapy's initiation. RESULTS: Changes in mean hair diameter and hair count compared to baseline were significant in both groups. The PRP group experienced a greater increase in mean hair count than the SVF-PRP group, and the SVF-PRP group had a marginally greater increase in hair diameter than the PRP group. These differences were not statistically significant compared to each other. The patient and physician assessment scores exceeded the mean (on a scale from 0: poor to 3: excellent) in both groups. CONCLUSION: Adding one SVF injection to two PRP treatment sessions versus three PRP injections alone had no significant difference in evaluated variables. If additional research demonstrates the same results, we suggest that multiple SVF injection sessions may be required to produce a statistically significant difference compared to PRP injection alone. Moreover, considering lower cost and greater accessibility of PRP, it can be used before SVF in the treatment of AGA.

INTRODUCTION: Dark under-eye circles or periorbital hyperpigmentation constitute a prevalent and challenging cosmetic problem with diverse etiologies and types. While modifying exacerbating habits can provide partial relief for the pigmentary and vascular factors associated with this condition, and despite the abundance of available treatment options, there is currently a lack of gold-standard evidence-based treatments proposed for curing this disorder. OBJECTIVES: This study aimed to assess the safety and effectiveness of carboxytherapy in treating periorbital hyperpigmentation. MATERIAL AND METHODS: In this 4-week single-arm clinical trial, 20 eligible Iranian patients with symmetric periorbital hyperpigmentation received weekly intradermal carboxytherapy. The treatment involved administering 10-20 mL of CO2 at a rate of 20 mL/min and a temperature of 15°C for a duration ranging from a few seconds to 1 min. Follow-up assessments were conducted 1 month after the final session. The primary outcome was defined as the changes in ΔE or the variations in pigmentation observed between the orbital and extra-orbital skin before and after the trial. RESULTS: The patients reported satisfaction with the statistically significant reduction in hyperpigmentation achieved through carboxytherapy in the lateral (p = 0.002), middle (p = 0.001), and medial (p = 0.001) regions of the periorbital area. The total response rate of the patients was estimated at 20%. Patient satisfaction exceeded ΔE changes, with no significant linear relationship (p = 0.084). CONCLUSION: Carboxytherapy can be proposed as an effective and safe treatment for periorbital hyperpigmentation.

INTRODUCTION: Lichen planopilaris (LPP) is one of the most common causes of scarring hair loss caused by immune-mediated inflammation resulting in atrophy and scaling. The key to preventing this irreversible hair loss is diagnosing and starting treatment at the earliest possible stage. As there is no definite cure for LPP, the therapy could be challenging. In the study, we conducted a single-blinded randomized clinical trial to evaluate the therapeutic effects, safety, and tolerability of platelet-rich plasma versus topical clobetasol in the treatment of LPP. METHOD: A randomized single-blinded controlled clinical trial was conducted in 24 LPP patients referring to our dermatology clinic between August 2022 and March 2023. Patients in the control group were treated with topical clobetasol 0.05% applied at night, and patients in the case group, in addition to topical clobetasol, received three sessions of PRP injection monthly. Both groups were assessed 1, 2, and 6 months after the start of the study by the Lichen Planopilaris Activity Index (LPPAI), physician and patient satisfaction, tolerability, and recording adverse effects. RESULTS: The average age in the clobetasol and PRP groups was 43.75 ± 13.51 and 42.75 ± 9.67, respectively (p = 0.83). In terms of gender, all 12 cases (100%) in the clobetasol group and 9 cases (75%) in the PRP group were female (p = 0.21). Both PRP and topical clobetasol effectively reduced LPPAI in the first 2 months; however, after 6 months, the LPPAI significantly increased in the clobetasol group (p = 0.001). There were no significant differences in LPPAI between the two groups at the beginning of the study and after 1 month. However, the mean LPPAI score in the clobetasol group was significantly higher than in the PRP group at 2 and 6 months after the start of the study (p = 0.01). Patient satisfaction with treatment increased in both groups during follow-up sessions, but at the end of the follow-up period, it was significantly higher in the PRP group (p = 0.03). Finally, the study did not have any serious adverse effects, and the pain experienced during PRP injection was tolerable for the patients. Overall, treatment tolerability was excellent in both groups. CONCLUSION: Given the different efficacy profiles, PRP could be considered a new and effective choice for the treatment of LPP.
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.

BACKGROUND: There are several types of dermatitis, each capable of causing enduring changes that extend beyond physical discomfort. In severe cases, dermatitis can significantly affect mental health, social interactions, and the overall quality of life. This study reports the burden of dermatitis in the Middle East and North Africa (MENA) region from 1990 to 2019, according to sex, age category, and socio-demographic index (SDI). METHODS: Publicly available data regarding the point prevalence, incidence, and years lived with disability (YLDs) were collected from the Global Burden of Disease 2019 study for both the MENA region and its constituent countries. The point prevalence, incidence, and YLDs of dermatitis were represented as counts and age-standardised rates with 95% uncertainty intervals (UIs). RESULTS: In 2019, the age-standardised point prevalence of dermatitis was 2744.6 (2517.8-3003.1) per 100,000 population, which was 2.3% lower than in 1990. The YLD rate was 92.3 (55.6-143.4) per 100,000 population, which was 3.1% lower than in 1990. The largest point prevalence rates were observed among those aged 70-74, for both sexes. The 2019 MENA/Global DALY ratio was not above one in any age group for either sex. During the period 1990 to 2019, there was no clear correlation between the burden of dermatitis and the SDI level. CONCLUSION: The dermatitis burden in the MENA region remained relatively stable from 1990 to 2019. Future prevention efforts should focus on improving healthcare access, health education, and workplace safety regulations.

INTRODUCTION: Acne vulgaris is a common skin condition that affects a significant percentage of adolescents, with scarring being one of its permanent complications. This study aims to compare the efficacy and safety of using botulinum toxin type A (BTA) in combination with cross-linked and non-cross-linked hyaluronic acid (HA) for the treatment of atrophic acne scars. METHOD: Our study is a randomized, double-blind clinical trial conducted on 16 patients with atrophic acne scars. The patients were randomly assigned to one of two groups: one group received a single session of BTA and crossed link HA combination, while the other group received two sessions of BTA and non-crossed link HA, 1 month apart. The patients were followed up at 3 and 6 months after baseline to evaluate the number and area of fine and large pores and spots, scar grading, patient satisfaction, and complications. RESULTS: The mean age of individuals in both the cross-linked HA and non-cross-linked HA groups was 32.75 ± 4.26 and 31.50 ± 8.48 years, respectively (p = 0.71). In terms of gender, three (37.5%) and seven (87.5%) individuals in the cross-linked and non-cross-linked HA groups were female, respectively (p = 0.11). There were no significant differences in the count and area of fine and large pores and spots between the two groups at baseline and the first follow-up session. However, in the second follow-up session, the non-cross-linked HA group had significantly better results than the cross-linked HA group in terms of large pores count and area (p = 0.01). In terms of changes over time, the non-cross-linked HA group showed significantly better improvements in the count and area of large pores compared to the cross-linked HA group (p = 0.03). Additionally, both groups experienced a significant decrease in the count and area of fine pores over time (p = 0.001), but the amount of changes was not statistically significant between the two groups (p = 0.06). Concerning acne grade, initially, 62.5% and 12.5% of cases in the cross-linked HA and non-cross-linked HA groups, respectively, had severe grades. However, in the last session, these percentages significantly decreased to 0% for both groups (p = 0.002 and 0.005, respectively). In terms of treatment complications, none of the patients experienced any adverse effects. CONCLUSION: The study demonstrated that both cross-linked HA and non-cross-linked HA were effective in reducing acne severity and improving the appearance of pores and spots. The treatments had similar effects on fine pores, spots, and overall acne severity. However, non-cross-linked HA appeared to have a better result on large pores compared to cross-linked HA.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic and recurrent disease of the axilla and groin with inflammatory lesions. There is no definitive medication or intervention to cure the disease. Radiofrequency (RF) is a modality to destroy the lesions by transferring heat into the skin. To date, few studies have been conducted to evaluate the efficacy and safety of RF at HS. METHODS: This 9-month, prospective, nonrandomized, and single-blinded study is a clinical trial conducted in 10 patients with refractory HS. In all patients, the initial grade of HS was evaluated. The procedure involved treating HS of the axilla with a endo-RF wave device. Post-treatment evaluation included: determination of the severity of the disease by a blinded dermatologist, the degree of patient satisfaction, tolerability in each patient, and complications of the procedure. We also evaluate the recurrence of the disease during a 6-month follow-up. RESULTS: The satisfaction level after the intervention among under-studied cases was excellent and good in six of cases. There was a significant difference in comparing the grading score of patients before and 3 months after receiving RF (P-value: 0.01). Regarding tolerability, eight of the patients could tolerate it. We had no complication after the intervention and four cases had not recurrence during a 6-month follow-up. CONCLUSION: Endo-RF is an effective and safe modality for treating HS however to prevent the recurrence, periodic therapy sessions are needed.
ABSTRACT
BACKGROUND: The appearance of skin scars is known as one of the main side effects of skin burns. Stromal vascular fraction (SVF), as a rich source of cell populations with tissue regeneration properties, plays an important role in the healing of skin lesions. Fractional CO2 lasers have occupied a special place in treating skin lesions, particularly skin scars, since their introduction. Our study aimed to compare the combination of SVF and fractional CO2 laser with fractional CO2 laser alone in the treatment of burn scars. METHOD: This double-blind clinical trial study was conducted on ten patients with burn scars that were treated three times with a fractional CO2 laser at site of burn lesions, and one of the two areas studied was randomly injected with SVF. Two months after completion of the procedure, patients' scars were assessed using the Vancouver scar scale (VSS), biometric criteria, and physician and patient satisfaction ratings. RESULTS: The results confirmed a significant improvement in VSS, cutometry, R7 criteria, complete density sonography, and skin density sonography in the fractional CO2 laser-treated group. The VSS criteria, epidermal thickness sonography, complete density sonography, and skin density sonography in the group treated with the combination of fractional CO2 laser and SVF also showed significant improvement. The VSS criteria and melanin index of Mexameter in the group treated with SVF in combination with fractional CO2 laser were significantly better than the group treated with fractional CO2 laser alone. Also, physician and patient satisfaction in the group treated with SVF injection in combination with fractional CO2 laser was significantly higher than the other group. CONCLUSION: The results confirm the efficacy of SVF injection in combination with fractional CO2 laser in the treatment of burn scars and can be considered as a treatment option for better management of these lesions. TRIAL REGISTRATION: The study protocol was retrospectively registered at Iranian Registry of Clinical Trials with code: IRCT20210515051307N1, Registration date: 2021-11-14, URL: https://www.irct.ir/trial/56337 .

OBJECTIVE: Psoriasis is a common, auto-immune skin disease characterized by abnormal proliferation and differentiation of keratinocytes. Studies revealed the role of stress stimulators in the pathogenesis of psoriasis. Oxidative stress and heat shock are two important stress factors tuning differentiation and proliferation of keratinocytes, regarding to psoriasis disease. BCL11B is a transcription factor with critical role in embryonic keratinocyte differentiation and proliferation. Given this, in keratinocytes we have investigated potential role of BCL11B in stress-induced differentiation. Furthermore, we searched for a potential intercommunication between BCL11B expression and psoriasis-related keratinocyte stress factors. MATERIALS AND METHODS: In this experimental study, data sets of psoriatic and healthy skin samples were downloaded in silico and BCL11B was chosen as a potential transcription factor to analyze. Next, a synchronized in vitro model was designed for keratinocyte proliferation and differentiation. Oxidative stress and heat shock treatments were employed on HaCaT keratinocytes in culture, and BCL11B expression level was measured. Cell proliferation rate and differentiation were analyzed by synchronized procedure test. Flow cytometry was done to analyze cell cycle alterations due to the oxidative stress. RESULTS: Quantitative reverse transcription polymerase chain reaction (qRT-PCR) data revealed a significant upregulation of BCL11B expression in keratinocytes, by 24 hours after initiating differentiation. However, it was followed by a significant down-regulation in almost all the experiments, including the synchronized model. Flow cytometer data demonstrated a G1 cell cycle arrest in the treated cells. CONCLUSION: Results indicated a remarkable role of BCL11B in differentiation and proliferation of HaCaT keratinocytes. This data along with the results of flow cytometer suggested a probable role for BCL11B in stress-induced differentiation, which is similar to what is happening during initiation and progression of normal differentiation.
ABSTRACT
PLACK syndrome is a relatively recently defined generalized peeling skin syndrome that has been reported with major skin manifestations and sometimes atypical features. We report the case of a 5-year-old boy with PLACK manifestations. Whole exome sequencing and subsequent Sanger sequencing identified a putative splice variant c.1209+2T>G in CAST (NM_001042440.5). Moreover, mRNA sequencing confirmed the abnormal alternative splicing of the CAST gene, leading to the addition of one nucleotide to the correct open-reading frame at the mRNA level. Segregation and expression analysis revealed that this loss-of-function via mRNA nonsense-mediated decay could be the causative pathogenic mechanism responsible for this patient's phenotype. This study extends our understanding of the various phenotypic and genotypic features of PLACK syndrome.

Female pattern hair loss (FPHL) is a hereditary form of hair loss in women and the most common patterned progressive hair loss in female patients with androgenetic alopecia (AGA). One of the best methods for treating hair loss in women is the finasteride treatment. This systematic review includes a summary of the pharmacology of finasteride and the effect of the drug on women, especially those in the menopausal age group, and is aimed at elucidating methods of preventing systematic side effects. A search of all published literature from 1999 to 2020 has been conducted with the use of PubMed/MEDLINE, Embase, PsycINFO, TRIP Cochrane, as well as Cochrane Skin databases. A total of 380 articles were found, of which 260 articles were removed and 87 review studies were excluded. Lastly, full texts of 33 original articles were reviewed and 14 articles that met the inclusion criteria were selected. Ten out of the 14 articles reported a high rate of alopecia recovery in women taking finasteride. Based on the results, it can be stated that 5 mg of oral finasteride per day could be an effective and safe treatment in normoandrogenic women with FPHL, especially when used in combination with other drugs, such as topical estradiol and minoxidil. We also found that topical finasteride is more effective than other topical formulas for treating hair loss.

BACKGROUND: Noninvasive laser for body fat contouring is a quickly growing field in the cosmetic dermatology. Surgical options carry disadvantages, such as the usage of anesthetics, swelling, pain and long time for recovery, so there is a growing public request for the techniques with fewer side effects and shorter recovery periods. Several new noninvasive body contouring ways have been advanced such as, cryolipolysis radiofrequency energy, suction-massage, high-frequency focused ultrasound, and laser therapy. Noninvasive laser improves the body's appearance by the elimination of excess adipose tissue, specifically in areas in which fat perseveres in spite of diet and exercise. METHODS: In this study the efficacy of Endolift laser was evaluated for reduction of excess fat in the arms and under abdomen. Ten patients with excess fat in the arms and under abdomen were enrolled in this study. The patients were treated by Endolift laser in the arms and under abdomen areas. The outcomes were evaluated by two blinded board certified dermatologists and by patients' satisfaction. The circumference of each arm and under abdomen was measured using a flexible tape measure. RESULTS: The results showed reduction in the fat and circumference of arms and under abdomen after treatment. The treatment was considered as effective methods with high patient satisfaction. Also no severe adverse effects were reported. CONCLUSION: Endolift laser can be a good alternative to surgical body fat contouring due to its efficacy, safety, minimal recovery time, low cost. Also Endolift laser does not require general anesthetics.

Two cases of pyogenic granulomas in burned skin were presented, a 17-month-old boy and a 7-year-old girl, being given oral propranolol and topical timolol. Both cases showed lesions improvement with no adverse effects, suggesting that beta-blocker therapy may have a positive impact on the treatment of pyogenic granuloma after burns.
ABSTRACT
Scars are among the most prevalent referral cases of dermatology clinics, including atrophic, hypertrophic, or keloidal scars. Approach to scar usually needs a holistic trend, attention to individualized characteristics, and combination therapy. Scars usually need multiple sessions of therapy and the use of combination therapeutic approaches to reach the most acceptable outcomes by safe modalities. Studies on scars are always one of the most important fields of research in medicine, especially in dermatology. For writing this review study, we searched all the databases to find the most relevant and the newest studies related to our topic, because based on expert opinion, this topic may be really practical and interesting for dermatologists and all physicians of various specialties or subspecialties who manage and treat various kinds of scars, including hypertrophic scars and keloids. Based on our results, we concluded that different procedures, which basically use needling, lasers, especially pulsed dye laser (PDL) and carbon dioxide (CO2) laser, and MesoBotox (micro-injection of botulinum toxin), are really promising therapeutic options for hypertrophic and keloidal scars and a combination of these therapies results in more efficacy and lesser side effects in the field of scar management.
ABSTRACT
Alopecia areata (AA), a polygenic and chronic autoimmune disease and there is no definitive cure. We aimed to evaluate latanoprost effects in patients with AA. In this controlled randomized double-blind clinical trial, we enrolled patients with AA randomly assigned to six groups of 18; Group 1 received latanoprost eye drops; group 2 minoxidil 5% solution; group 3 latanoprost eye drops and minoxidil 5% solution; group 4 betamethasone and minoxidil 5% solution; group 5 betamethasone solution and latanoprost eye drops; group 6 (the control group) betamethasone solution. The alopecia severity in patients before and after treatment was assessed by severity of alopecia tool (SALT). One hundred and eight patients, 50% male (mean age: 32.6 ± 10.4) were studied. The overall SALT score decreased in all. After 2 weeks, patients receiving betamethason-minoxidil and betamethason-latanoprost showed more decline in their SALT than other groups. In final, there was statistically significant difference among betamethasone-latanoprost group with minoxidil, betamethasone-minoxidil and betamethasone groups. Regrowth was higher in latanoprost and betamethasone-latanoprost groups than minoxidil. Topical latanoprost added to therapeutic efficacy of topical betamethason and minoxidil in treating patchy AA, suggesting it being beneficial and safe adjuvant therapy and add to efficacy of topical treatments without any adverse effects.

BACKGROUND: Subcision method is one of the main techniques for treatment of acne scars or stromal-vascular fraction (SVF) and combined therapy can improve treatment strategy. OBJECTIVE: To use subcision method along with SVF for treatment of acne scar and comprised with alone subcision method. MATERIALS AND METHODS: In this double-blind clinical trial study, 10 patients with acne scars were entered into the study. Subcision technique was randomly performed on one side of the face and subcision technique plus SVF on opposite side of the face. All patients were examined before treatment and after 3 months by Visioface for volume, area, and depth of scars, as well as thickness and density of the epidermis and dermis of the scars in question. In addition, doctor's and patients' satisfaction, tolerability, and safety were determined after 3 months of treatment. Finally, statistical analysis was done by SPPS, version 25. RESULTS: In terms of volume and area of scars, the mean percent change was 46.55 ± 13.92 and 44.60 ± 5.76, for the case group, and 13.31 ± 9.27 and 11.28 ± 9.64 for the control group, respectively. So, combined therapy led to significant recovery compared with alone subcision method (p value < 0.001). In both interventions, the increase of density and thickness was proven after treatment, also a significant difference in complete, epidermal, and dermal thickness and epidermal density variables was observed between combined therapy and alone subcision (p value < 0.05). Mean score of doctor's and patients' satisfaction in combined therapy (7.10 ± 0.74 and 7.10 ± 0.99, respectively), was also significantly higher than subcision alone (5.50 ± 0.53 and 5.30 ± 1.25, respectively). Finally, no complications were observed in the patients. CONCLUSION: According to the acquired results, combined therapy can be considered as effective and safe treatment for acne scars with significant higher efficacy compared with subcision alone.

BACKGROUND: Tofacitinib, a potent JAK inhibitor, has gained increasing interest, in recent years, among dermatologists for the management of refractory alopecia areata. Despite a growing number of studies on its safety and efficacy, there is still a lack of clarity, especially in the pediatric population, in treatment considerations such as proper dosage, treatment duration, side-effect profile, and therapeutic strategies to guide clinicians. METHODS: Multiple databases were systematically searched. Following the PRISMA diagram, of a pool of 601 papers, seven met a checklist of inclusion criteria. These were observational studies including a total of 59 patients from four to 19 years of age. RESULTS: In the evaluated studies, tofacitinib was administered either orally at a 2.5 to 15 mg daily (mostly 5 mg twice a day) dosage for 2 to 38 months or in the form of a 2% topical solution for 3-17 months. Metanalysis showed that 49% (95% CI: 29%-69%, I2 = 59.94%) of patients experienced a reversal of alopecia after a minimum of 3 to 9 months of therapy. Fifty-five percent (95% CI: 23%-86%, I2 = 75.07%) and 41% (95% CI: 23%-59%, I2 = 0.00%) showed Good/complete and partial response rates, respectively. Oral administration was significantly more efficacious than topical application (73% vs 23%, p-Value = 0.04). Few side effects such as diarrhea and mild liver transaminases abnormalities were noted in several patients. CONCLUSION: Results of this review suggest that tofacitinib at 2.5-15 mg daily (especially 5 mg twice daily) oral formulation or 2% topical solution can be regarded as a viable alternative or adjunct to the conventional treatment options for moderate to severe forms of alopecia areata in children owing to its acceptable efficacy and side-effect profile. However, uncertainties continue to exist around treatment strategies including initial and maintenance dosages, route of administration, dose adjustments, the timing of tapering or discontinuation, and associated treatment modalities.

BACKGROUND: Acne is the most common skin disorder which is known as a chronic inflammatory disease with psychological burden and reduced quality of life. Adipose tissue-derived stromal vascular fraction (SVF) is recognized as a source of regenerative cells and improves the quality of skin by increasing collagen content. To date, a few studies have been performed on the therapeutic role of SVF in the treatment of acne scars. METHODS: This randomized, single-blinded clinical trial was performed on 7 patients with acne scars. In all patients, the initial grade of acne (volume, area and depth) was evaluated and ultrasound of the relevant scar was performed to evaluate neocollagenesis. As a spilt face study, for treating the scars, we used nanofat subcutaneously on one side of the face (control group) and combination of nanofat subcutaneously and SVF intradermally on the opposite side (intervention group). The patients were evaluated for severity of acne by visioface after one month, also for thickness of epidermis and dermis by ultrasound after one month and three months. RESULTS: All of the apparent findings of scars improved in two groups after one month, but these changes were significant just for the group treated with SVF (p value < 0.05). Epidermal, dermal and complete thicknesses during the first month in both control and intervention groups were significantly increased (p value < 0.05) but between the first and third months, there was no significant difference in the variables (p value > 0.05). The findings showed that dermal and complete thicknesses of the skin in the first month were different between two groups significantly (p value: 0.042 and 0.040, respectively). CONCLUSION: The use of SVF in the treatment of patients with acne scars accelerates the improvement of volume, area and depth of the scar by increasing collagen content and the dermal thickness, so it can be used as a potentially effective treatment for these patients.

BACKGROUND: Acne scars have important psychosocial suffering for patients. Several interventions have been utilized to treat acne scars that have different degrees of efficacy and side effect. Multimodal method can attain better results to improving the physical appearance of the patients that can significantly increase the quality of life. Subcision is a recognized treatment procedure particularly for rolling acne scars, but it needs modification to increase the effect of procedure. AIMS: The aim of the study was to assess the efficacy and safety of Endo-Radiofrequency (Endo-RF) subcision in acne scars treatment. METHODS: In this study, 9 adult patients with atrophic acne scars were enrolled. The patients receive Endo-RF subcision one time and followed up for 6 months. Outcome was measured using biometric assessment by Visioface 1000 D, Mexameter and skin ultrasound imaging system, post-treatment photographs and patient's satisfaction.
