Androgenetic alopecia, the most common cause of hair loss affecting both men and women, is typically treated using pharmaceutical options, such as minoxidil and finasteride. While these medications work for many individuals, they are not suitable options for all. To date, the only non-pharmaceutical option that the United States Food and Drug Administration has cleared as a treatment for androgenetic alopecia is low-level laser therapy (LLLT). Numerous clinical trials utilizing LLLT devices of various types are available. However, a myriad of other physical treatments for this form of hair loss have been reported in the literature. This review evaluated the effectiveness of microneedling, pulsed electromagnetic field (PEMF) therapy, low-level laser therapy (LLLT), fractional laser therapy, and nonablative laser therapy for the treatment of androgenetic alopecia (AGA). It also explores the potential of multimodal treatments combining these physical therapies. The majority of evidence in the literature supports LLLT as a physical therapy for androgenetic alopecia. However, other physical treatments, such as nonablative laser treatments, and multimodal approaches, such as PEMF-LLLT, seem to have the potential to be equally or more promising and merit further exploration.

Background and aim The majority of acne has the potential to transform into facial scars, which have a physical and psychological effect on the individual. There are plenty of treatment options to manage such scars. The aim of this study is to assess the comparative effect of the injection of platelet-rich plasma (PRP) alone, with that of the injection of PRP with microneedling, in the reduction of atrophic facial acne scars.  Methods A total of 30 participants were included in this study, divided into two groups (n = 15). Patients in Group I received intradermal injection of PRP only, and Group II included patients receiving intradermal injection of PRP with microneedling. The scar appearance was evaluated at baseline, after one, two, and three months using Goodman Baron\'s scar scale. The statistics were analysed using the Chi-square and Student\'s t-tests.  Results Patients in the PRP with microneedling group had lower acne scar scores on the Goodman Baron scale compared to those who received only PRP. The acne scores were statistically significant (p-value < 0.05) in the second and third months of treatment in Group II.  Conclusion The addition of microneedling to PRP has proven to be effective in the reduction of facial acne scars. However, different types of scars require different modalities of treatment, and the final decision lies in the hands of the operator and the requirements of the patients.

Acne scars can greatly impact patient quality of life. While treatment options have included mi- croneedling, the recent addition of platelet-rich plasma (PRP) to this regimen has led to an increased popularity of combination treatment. Here, we aimed to review the efficacy of microneedling and PRP therapies and review the literature on combination treatment for acne scars.

Vitiligo is considered an autoimmune disease, and its treatment is challenging. We assessed and compared the effect of fractional erbium:yttrium-aluminum-garnet (Er:YAG) laser-assisted delivery of platelet-rich plasma versus microneedling (Mn) with platelet-rich plasma (PRP) in enhancing skin repigmentation in localized stable vitiligo patients. In total, 40 patients with localized stable vitiligo were selected in a random manner into two similar groups (20 each). Group (A) was subjected to fractional Er:YAG laser combined with platelet-rich plasma and Group (B) was subjected to microneedling combined with platelet-rich plasma. The procedure was repeated every 2 weeks for up to 6 months. Each individual was assessed clinically utilizing Vitiligo Area Scoring Index (VASI). Fractional Er:YAG + PRP group achieved better pigmentation100% (excellent 30%, very good 15%, good 30% and satisfactory 25%) which is comparable to Mn + PRP where 80% of cases demonstrate repigmentation (20% very good, 10% good and 50% mild). When comparing the VASI scores for both groups after therapy to the baseline VASI, there was a statistically significant decrease [p = 0.001 for group(A) and 0.003 for group(B)]. Regarding the treatment side effects, there was significantly (p = 0.048) side effects among cases treated with microneedling group(B) (25%) than those fractional Er:Yag laser therapy group(A) (5%). Both forms of therapy demonstrated induction of repigmentation of vitiligo, but fractional Er:YAG laser efficacy is greater when combined with platelet-rich plasma.Clinical trials.gov identifier: NCT05511493.

UNASSIGNED: Vitiligo is an inveterate disease of great aesthetic concern presenting with depigmented macules and patches. It is often incorrigible to medical treatment.
UNASSIGNED: To study the clinical profile of vitiligo patients and evaluate the effect of 5% 5-fluorouracil (5-FU) cream with microneedling.
UNASSIGNED: This observational analytical study was conducted from November 2019 to July 2021. A total of 33 adult vitiligo patients were treated with oral mini-pulse (dexamethasone) therapy and topical corticosteroid (clobetasol propionate 0.05%). Patient\'s total number of vitiligo lesions with <10-cm size were counted and half of the lesions were treated with 5-FU + microneedling (Group A), while a remaining number of lesions were not treated with 5-FU + microneedling (Group B). In the case of the odd number of lesions, the total number of lesions minus one was considered and then divided into equal numbers for treatment. The procedure was performed every 2 weeks for 3 months. Clinical improvement was assessed monthly till 6 months by serial clinical photographs and grading scores.
UNASSIGNED: Initiation of repigmentation started in the first month in Group A, whereas in Group B, it was seen in the second, which was statistically significant (P < 0.0001). Excellent improvement (>75% repigmentation) was noted in Group A as compared to Group B at the end of 6 months (P < 0.0001).
UNASSIGNED: Needling with 5% 5-FU appears to be a simple, safe, and effective treatment in vitiligo. It can be used in poor responders to conventional therapy.

BACKGROUND: Gingival inflammation, a hallmark of periodontal diseases, serves as a critical focus in oral health research. Characterized by redness, swelling, and bleeding of the gingival tissues, it reflects the body\'s response to bacterial biofilms accumulating on the tooth surfaces. This inflammatory process, initiated by the interaction between oral bacteria and the host immune system, can lead to a spectrum of periodontal conditions ranging from mild gingivitis to severe periodontitis. Understanding the efficacy of various methods to treat gingival inflammation is essential for refining treatment strategies and enhancing patient satisfaction in the realm of gingival inflammation.
OBJECTIVE: The objective of the study was to evaluate the efficacy of employing the microneedling technique with olive oil on gingival inflammation and plaque accumulation in individuals with gingivitis.  Materials and methods:Twenty-four individuals diagnosed with plaque-induced gingivitis were selected from Saveetha Dental College, Chennai. Participants were randomly assigned to one of two groups: Group A, comprising 12 individuals who received mechanical periodontal treatment only and Group B, consisting of 12 individuals treated with dermapen and topical olive oil. This involved the creation of microholes in the gingival tissue to enhance the concentration and penetration of the oils through the gingival tissues. Post-intervention assessments of gingival and plaque status were conducted using a gingival index and a plaque index at baseline, one, two, and four weeks. Statistical analysis was done using IBM SPSS Statistics for Windows, version 23 (IBM Corp., Armonk, NY, USA). Intergroup analysis was done using Mann-Whitney test and intra-group analysis was done using Kruskal-Wallis test for all the study parameters. Statistical significance was set at a p-value of less than 0.05.
RESULTS: The mean plaque index scores were 2.02 ± 0.12 and 2.29 ± 0.21 in the subgingival scaling and microneedling with olive oil group respectively in baseline. The scores were 1.83 ± 0.29 and 0.57 ± 0.16 in the subgingival scaling and microneedling with olive oil group respectively at the end of four weeks. The results of plaque index scores were statistically significant between the control and the intervened groups at the end of four weeks with a p value of 0.01*. The mean gingival index scores were 2.09 ± 0.16 and 2.37 ± 0.17 in the subgingival scaling and microneedling with olive oil group in the baseline respectively. The scores were 1.88 ± 0.23 and 0.96 ± 0.21 in the subgingival scaling and microneedling with olive oil group respectively at the end of four weeks. The results of gingival index scores were statistically significant between the control and the intervened groups at the end of four weeks with a p value of 0.01*.
CONCLUSIONS: Our research showcased a novel and effective technique, unveiling a significant enhancement in gingival health accompanied by a reduction in both the average gingival index and plaque index.

BACKGROUND: Severe acne breakouts often lead to atrophic acne scars, which affect millions of people worldwide and can significantly affect a person\'s self-confidence and self-image. Given the difficulty in treating atrophic acne scars, this study aims to investigate the efficacy of topical phenytoin in the treatment of atrophic acne scars.
METHODS: This split face clinical trial on 25 patients between the ages of 18 and 40 involved the application of microneedling on one side of the face, with three sessions taking place over the course of a month. On the other side, a 1% phenytoin cream was administered three times daily for 1 week following the microneedling procedure. Baseline information was collected for all patients, and follow-up assessments were conducted during the treatment sessions and 2 months after the last session. The assessments included evaluating the number and area of pores and spots, determining scar severity, assessing patient satisfaction, and recording any potential complications.
RESULTS: Among patients, 20 individuals (80%) were females, and the average age of the participants was 35.96 ± 9.23. In terms of the fine pore area, despite the fine pore count, both groups showed improvement over time (p: 0.03 vs. 0.06). Also, regarding large pore count and area, and the count and area of spots, both groups showed improvement over time (p: 0.001). However, there were no significant differences between the two groups (p > 0.05). On the other hand, when it comes to acne scar grade and patients\' satisfaction, the phenytoin group outperformed the control group in all follow-up sessions and this difference was found to be significant (p: 0.001). It is worth noting that no complications were observed among any of the patients.
CONCLUSIONS: It appears that combining phenytoin cream with microneedling has a more effective therapeutic outcome in enhancing atrophic acne scars, when compared to microneedling alone, and this method can be regarded as a viable alternative in treating these types of scars.

UNASSIGNED: Severe post-acne scarring has been implicated as a cause of considerable psychological distress, mainly among adolescents. Subcision and microneedling are cutting-edge treatment options available nowadays.
UNASSIGNED: In this study, we aimed to compare the efficacy of microneedling with platelet-rich plasma (PRP) against subcision with PRP in treating atrophic post-acne scars in a split-face study design.
UNASSIGNED: Fifty patients with atrophic post-acne facial scars were included in this prospective interventional study. Group A included the left side of the face managed by microneedling with PRP and group B included the right side of the face that was subjected to subcision with PRP. Results were assessed based on Goodman and Baron qualitative and quantitative grading.
UNASSIGNED: In our study, at the end of the treatment, on the left side, 5 (10%) had 1 grade of improvement showing good response, 35 (70%) had 2 grades of improvement showing very good response, and 10 (20%) had 3 grades of improvement showing excellent response. On the right side, 1 (2%) patient had no improvement in acne grade showing poor response, 9 (18%) had 1 grade of improvement showing good response, 25 (50%) had 2 grades of improvement showing very good response, whereas 15 (30%) had 3 grades of improvement showing excellent response.
UNASSIGNED: Till date, apart from ours no other study has compared the two modalities head-to-head with adjuvant PRP in both groups. Although both modalities showed statistically significant results individually, there was no significant difference in qualitative improvement of acne scars between the two groups.

UNASSIGNED: Scarring is a biological process of wound repair which leads to a difference in the normal structure and function of the skin and manifests as a depressed or raised area. Treatment of scars is challenging. A number of therapeutic approaches like surgical techniques and non-surgical techniques are performed to improve scarring.
UNASSIGNED: The aim of this study was to compare the outcome of subcision followed by microneedling versus subcision followed by microneedling and topical platelet-rich plasma (PRP) in atrophic scars.
UNASSIGNED: A comparative prospective study was conducted at a tertiary care hospital in North India to compare the efficacy of subcision followed by microneedling versus subcision followed by microneedling and topical PRP. A total of 40 cases were taken and were randomly divided into two groups, A and B of 20 patients in each group. Topical PRP was applied as an additional therapy in Group B in the same sitting. Minimum three sittings were done in each patient at an interval of 4 weeks and results were assessed after 1 month of the third session. The statistical software used is Microsoft Excel and SPSS software program, version 24.0 for analysis of data and Microsoft Word to generate graphs and tables.
UNASSIGNED: Improvement in scar grading was more in Group B as compared to Group A with statistically significant difference (P = 0.032). There was an improvement in scar grading from grade 4 scar to grade 2 in 15% and 30% patients of Groups A and B, respectively, with improvement in skin texture and pigmentation more in Group B.
UNASSIGNED: PRP proved to add to the improvement of grade of atrophic scars when combined with subcision and microneedling.

Background Gingival pigmentation (GP), characterized by the presence of melanin in the gingival tissues, is a common aesthetic concern in dental practice. While it poses no inherent health risks, the visible discoloration may cause psychological distress for individuals seeking optimal dental aesthetics. Understanding the efficacy of various methods is essential for refining treatment strategies and enhancing patient satisfaction in the realm of gingival depigmentation (GD). Aim The objective of the study was to compare the effectiveness of scalpel and microneedling (MN) with ascorbic acid in the treatment of GD. Materials and methods Sixteen patients who had a complaint of GP were included in the study, of whom eight were allocated for depigmentation with a scalpel, and the other eight patients were treated with the MN technique with ascorbic acid. Postoperative wound healing scores were evaluated on the first and seventh days, respectively. The intensity of depigmentation was assessed at baseline, in the first month, and at the end of the third month, respectively. Results The mean Dummett-Gupta Oral Pigmentation Index (DOPI) score at baseline was 2.65±0.16 and 2.61±0.17 in the surgical and microneedling groups with ascorbic acid, respectively. The mean DOPI score at the end of the third month was 1.67±0.39 and 0.87±0.17 in the scalpel and MN with ascorbic acid groups, respectively. There was a statistically significant difference between the scalpel and MN with ascorbic acid groups at the end of the first and third months, respectively, where MN with ascorbic acid showed aesthetically pleasing outcomes. Patients treated with the scalpel technique showed incomplete healing and ulceration on the first and seventh days after the procedure when compared to the MN technique with ascorbic acid. The healing index scores were statistically significant in the MN with ascorbic acid group. Conclusion The MN technique with ascorbic acid is a successful technique for treating GD. It showed aesthetically gratifying outcomes when compared to the conventional surgical technique.
