AIMS AND OBJECTIVES
The aim of this study is to systematically review randomized controlled clinical trials (RCTs) studying various types of regenerative medicine methods (such as platelet-rich plasma, stromal vascular fraction, cell therapy, conditioned media, etc.) in treating specific dermatologic diseases. Rejuvenation, scarring, wound healing, and other secondary conditions of skin damage were not investigated in this study.
METHOD
Major databases, including PubMed, Scopus, and Web of Science, were meticulously searched for RCTs up to January 2024, focusing on regenerative medicine interventions for specific dermatologic disorders (such as androgenetic alopecia, vitiligo, alopecia areata, etc.). Key data extracted encompassed participant characteristics and sample sizes, types of regenerative therapy, treatment efficacy, and adverse events.
RESULTS
In this systematic review, 64 studies involving a total of 2888 patients were examined. Women constituted 44.8% of the study population, while men made up 55.2% of the participants, with an average age of 27.64 years. The most frequently studied skin diseases were androgenetic alopecia (AGA) (45.3%) and vitiligo (31.2%). The most common regenerative methods investigated for these diseases were PRP and the transplantation of autologous epidermal melanocyte/keratinocyte cells, respectively. Studies reported up to 68.4% improvement in AGA and up to 71% improvement in vitiligo. Other diseases included in the review were alopecia areata, melasma, lichen sclerosus et atrophicus (LSA), inflammatory acne vulgaris, chronic telogen effluvium, erosive oral lichen planus, and dystrophic epidermolysis bullosa. Regenerative medicine was found to be an effective treatment option in all of these studies, along with other methods. The regenerative medicine techniques investigated in this study comprised the transplantation of autologous epidermal melanocyte/keratinocyte cells, isolated melanocyte transplantation, cell transplantation from hair follicle origins, melanocyte-keratinocyte suspension in PRP, conditioned media injection, a combination of PRP and basic fibroblast growth factor, intravenous injection of mesenchymal stem cells, concentrated growth factor, stromal vascular fraction (SVF), a combination of PRP and SVF, and preserving hair grafts in PRP.
CONCLUSION
Regenerative medicine holds promise as a treatment for specific dermatologic disorders. To validate our findings, it is recommended to conduct numerous clinical trials focusing on various skin conditions. In our study, we did not explore secondary skin lesions like scars or ulcers. Therefore, assessing the effectiveness of this treatment method for addressing these conditions would necessitate a separate study.

INTRODUCTION
Despite the promising results in terms of effectiveness of anticancer treatments, a wide range of dermatologic adverse reactions have been reported. Among them, skin photosensitivity, defined as a range of dermatologic conditions caused or exacerbated by sunlight exposure, is an emerging adverse event.
EVIDENCE ACQUISITION
A review of the current literature was performed to report the most characteristic phototoxic and photoallergic reactions associated with anticancer therapies, as well as other characteristic manifestations potentially related to photo-exposure, including UV recall, vitiligo-like reactions, drug-induced cutaneous lupus erythematosus, and UV-induced hyperpigmentation.
EVIDENCE SYNTHESIS
A total of 30 manuscripts were collected in the present review, reporting several phototoxic and photoallergic reactions associated with anticancer therapies.
CONCLUSIONS
Photosensitivity reactions are an increasing challenge in cancer management. The raising awareness about this adverse event has increased the identification of potential photosensitizing drugs as well as its prevention and the management. However, more studies are required to improve the knowledge of this cutaneous toxicity and to define a personalized treatment strategy.

Background Numerous clinical signs and symptoms are thought to be associated with insulin resistance. The purpose of this study was to examine the prevalence of insulin resistance among male medical students attending a private Saudi Arabian institution, based on clinical indications. Methods A convenient non-probability sample consisting of 241 male medical students was used to conduct cross-sectional research. Each participant had an in-person interview as well as anthropometric measurements. The interview consisted of a questionnaire that was used to assess demographic data and clinical manifestations related to insulin resistance. Results The study demonstrated the connection between a few dermatological symptoms and waist circumference as an indicator of insulin resistance. In both the high and normal waist circumference groups, acne was the most common symptom. There was no correlation found between waist circumference and psoriasis, hidradenitis suppurativa, androgenic alopecia, alopecia areata, or vitiligo. Nevertheless, as an indicator of insulin resistance, waist circumference was statistically significantly correlated with both skin tags and acanthosis nigricans. Most students had excessive day sleep, foggy brains, struggled with planning and solving problems, and had a memory that became worse in the past few years. In addition, many students feel hungry even after eating some sweets and usually have extreme thirst. Conclusion Among medical students, skin tags, acanthosis nigricans, and acne were the most prevalent dermatological manifestations. Clinicians need to be aware that skin conditions, sleep difficulties throughout the day, changes in cognition, and food cravings might all be indicators of internal changes and/or illnesses such as diabetes and prediabetes.

Background Psoriasis is a common chronic inflammatory skin disease with an autoimmune etiology. Psoriasis has been presumed to be associated with several autoimmune diseases. We sought to determine the prevalence of autoimmune diseases in patients with psoriasis in a large referral tertiary care center. Methods This is a retrospective and cross-sectional chart review of patients with confirmed psoriasis diagnoses in the dermatology clinic of King Abdulaziz Medical City, Riyadh, Saudi Arabia. The electronic charts of patients were individually reviewed for autoimmune diseases such as hypothyroidism, hyperthyroidism, alopecia areata, vitiligo, atopic dermatitis, and inflammatory bowel diseases like Crohn's disease and celiac diseases. Results A total of 839 cases were included, 56.4% of whom were females. Most patients were between 31 and 50 years old (37.1%). The most common autoimmune disease was hypothyroidism (6.8%), seen more in females. The second most common autoimmune disease was alopecia areata (3.6%), followed by atopic dermatitis (2.9%). Rheumatoid arthritis, systemic lupus erythematosus, and inflammatory bowel diseases were uncommon in our cohort. Conclusion In this single-center retrospective cohort of patients with psoriasis, hypothyroidism and alopecia areata were the most commonly encountered autoimmune diseases. Larger, multi-center studies are needed to evaluate the prevalence of autoimmune diseases among patients with psoriasis.

BACKGROUND
Vitiligo is a dermatological condition characterized by the appearance of white spots or patches on the skin due to the loss of skin pigment called melanocytes. The estimated prevalence of vitiligo is about 0.5-2% of the world population, but in India, the prevalence rate varies from 2 to 8%, depending on the region. This study aimed to assess drug prescribing patterns in vitiligo patients.
MATERIALS AND METHODS
A prospective cross-sectional study was carried out in the Dermatology Department of Government General Hospital, Andhra Pradesh, India, from December 2019 to 2020. Patients aged ≥18 years, both genders, and diagnosed and receiving treatment for vitiligo were included in the study. All medicines prescribed to the patients were collected on the predesigned case report form. Ethical approval for this study was taken from the Institutional Ethics Committee of Rajiv Gandhi Institute of Medical Science (RIMS). The collected data were analyzed by using SPSS version 18.
RESULTS
The most commonly prescribed class of drugs was corticosteroids (42.9%), followed by calcineurin inhibitors (13.4%), vitamins (14.6%), basic fibroblast growth factor (BFGF) (9.5%), moisturizers (6.9%), antihistamines (6.5%), and minerals (6.2%). Among corticosteroids, betamethasone was the most commonly prescribed drug, followed by clobetasol propionate. Topical drugs were prescribed more often than orally.
CONCLUSION
The prescription pattern in vitiligo patients is as per the guidelines and recommendations. However, further studies using multiple centers are recommended to verify our findings.

Review
INTRODUCTION
Vitiligo is a chronic, autoimmune condition characterized by skin depigmentation caused by inflammatory-mediated melanocyte degradation. Treatment of vitiligo is challenging due to the chronic nature of the condition. Ruxolitinib cream 1.5% was recently approved by the Food and Drug Administration (FDA) as a Janus kinase 1 and 2 inhibitor for use in nonsegmental vitiligo for those 12 years and older.
AREAS COVERED
The purpose of this review is to describe the role of ruxolitinib in treating nonsegmental vitiligo.We searched PubMed using search terms nonsegmental vitiligo, jak inhibitor, and ruxolitinib. Clinicaltrials.gov was used to identify clinical trial data including efficacy, pharmacodynamics, pharmacokinetics, safety, and tolerability.
EXPERT OPINION
In both phase II and phase III (TRuE-V1 and TRuE-V2) trials, ruxolitinib cream 1.5% improved repigmentation with minimal adverse effects. Topical ruxolitinib is a much needed new vitiligo treatment option. Real life efficacy may not match that seen in clinical trials if the hurdle of poor adherence to topical treatment is not surmounted.

Randomized Controlled Trial
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.

BACKGROUND
The adhesive properties of vitiligo melanocytes have decreased under oxidative stress., cytoskeleton proteins can control cell adhesion. Paeoniflorin (PF) was proved to resist hydrogen peroxide (HO)-induced oxidative stress in melanocytes via nuclear factorE2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway.
OBJECTIVES
This study was to investigate whether PF exerts anti-oxidative effect through influencing cytoskeleton markers or potential signaling pathway.
METHODS
Human Oxidative Stress Plus array was used to identify the differentially expressed genes between HO + PF group and HO only group, in PIG1 and PIG3V melanocyte cell lines respectively. Western blotting was used to verify the PCR array results and to test the protein expression levels of cytoskeleton markers including Ras homolog family member A (RhoA), Rho-associated kinase 1 (ROCK1) and antioxidative marker Nrf2. Small interfering RNA was used to knock down PDZ and LIM domain 1 (PDLIM1).
RESULTS
PF increased the expressions of PDLIM1, RhoA and ROCK1 in HO-induced PIG1, in contrast, decreased the expressions of PDLIM1 and ROCK1 in HO-induced PIG3V. Knockdown of PDLIM1 increased the expressions of RhoA and Nrf2 in PF-pretreated HO-induced PIG1, and ROCK1 and Nrf2 in PF-pretreated HO-induced PIG3V.
CONCLUSIONS
PF regulates RhoA/ROCK1 and Nrf2 pathways in PDLIM1-dependent or independent manners in HO-induced melanocytes. In PIG1, PF promotes PDLIM1 to inhibit RhoA/ROCK1 pathway or activates Nrf2/HO-1 pathway, separately. In PIG3V, PF directly downregulates ROCK1 in PDLIM1-independent manner or upregulates Nrf2 dependent of PDLIM1.
