RESUMO
Acne vulgaris is a common condition, mostly involving teenagers. Post-acne scarring can cause many psychosocial problems. Treatments include topical agents, chemical peels, ablative lasers, fractional lasers, and more invasive approaches like subcision and surgery. We aimed to build on data regarding the efficacy and safety of endo-radiofrequency subcision in treating acne scars. This trial involved 30 patients (26 females and 4 males) suffering from acne scars. Patients were treated with endo-radiofrequency subcision. Outcomes were measured by Goodman and Baron scores (GBA), Patient's Global Assessment (PGA), and Investigator's Global Assessment (IGA). All 30 patients completed the trial. The mean baseline quantitative Goodman and Baron score was 13.2 ± 4.31, which improved to 5.37 ± 2.83 by the end of the study (P < 0.001). A significant improvement was also noted in the Goodman and Baron qualitative assessment of acne scars (P < 0.001). According to the PGA, the improvement rate was 25-50% in most patients (60%), while according to the IGA, the improvement rate was 25-49% in most patients (50%). Eleven patients (36.7%) were satisfied with the treatment process, while the other 19 patients (63.3%) were very satisfied. Side effects were minimal and transient. A single session of endo-radiofrequency subcision is a fairly safe and effective treatment, with a high satisfaction rate among treated patients.

INTRODUCTION: Tissue engineering is a revolutionized biotechnology that utilizes biomaterials in regenerative medicine. Nowadays, there is a trend in employing autologous-based materials in aesthetic medicine. In this review, we discuss safety and efficacy of autologous-based fillers in the fields of aesthetic dermatology, and describe the details of preparation and injection methods based on current literature. EVIDENCE ACQUSITION: PubMed, Scopus, Web of science, Embase and Google scholar were searched for studies which evaluated efficacy of autologous-based filler in the field of aesthetic dermatology from January 2000 until August 2022. Nineteen articles including five randomized clinical trials, ten prospective and four retrospective studies were selected for this review. EVIDENCE SYNTHESIS: Most of the studies evaluated use of biofillers in rejuvenation (twelve articles) and the remaining were in atrophic scars (six articles) and striae distensae (one article). Adjuvant treatments included liquid platelet rich growth factor (PRGF), autologous cultured fibroblast, adipose tissue micrograft, microneedling, fractional carbon dioxide laser and subcision. Application of biofillers is a safe alternative therapeutic option for soft tissue augmentation. CONCLUSIONS: Application of biofillers is especially recommended in patients who seek low-cost rejuvenation methods and those with a past history of granulomatous reactions to the other fillers. It provides the advantage of immediate filling effects with long-lasting efficacy.

Anogenital warts are the most common sexually transmitted infection causing economic and psychosocial issues. Efficacy of zinc has been proved in treating nongenital warts, but its role in treating anogenital warts is not clear. This study was conducted to assess whether oral zinc gluconate in combination with cryotherapy effectively treated anogenital warts. A randomized double-blind, split-side, placebo-controlled trial was conducted on 50 patients suffering from genital warts. The patients were treated for 2 months with a combination of four sessions of cryotherapy and oral zinc gluconate versus placebos. Follow-up was performed at every 2 weeks based on the number of warts. The number of genital warts reduced significantly in both groups during treatment with cryotherapy, but no significant differences were observed between treatment with zinc and placebo. Patients in the zinc gluconate group reported significantly higher gastrointestinal adverse effects than those in the placebo group. This indicates that using oral zinc gluconate appeared to have no significant advantage over placebo in treating and reducing the number of genital warts; however, a longer duration of follow-up and pre-intervention serum level of zinc were necessary to evaluate the role of oral zinc therapy.

Post-acne scarring is the most common permanent consequence of acne vulgaris. Subcision is an intervention in which a needle or blunt cannula is inserted under the scar and moved back and forth to cut fibrotic strands and form new connective tissue, thereby elevating the atrophic scars. In this study, we reviewed the efficacy and adverse effects of different subcision techniques alone or in combination with other modalities to manage acne scars. The terms (subcision), (subcision AND acne scar), and (subcision AND scar) were searched in PubMed and Google Scholar. We included all available reports on clinical trials written in English and published before June 2022. A total of 16 relevant articles were identified after reviewing the abstracts and full texts. Four articles compared blunt cannula-based subcision as a modified technique with needle-based subcision as a conventional method, while the others investigated the combination of subcision with other modalities. According to our findings, subcision is a safe and effective method for treating atrophic acne scars. Needle-based subcision and cannula-based subcision offer comparable efficacy, with the latter causing fewer side effects and inducing greater patient satisfaction. Combining subcision with the application of autologous tissues (platelet gel) or artificial materials (hyaluronic acid gels and threads) as fillers can improve outcomes and prevent the re-depressing of scars, as can its combination with frequent suctioning. Combinations with microneedling or fractionated microneedle radiofrequency have also been safe and effective. We conclude that modifications of the subcision procedure lessen its side effects, and combination therapies improve its efficacy.

Brimonidine is a vasoconstrictive agent used to treat several dermatologic disorders. Here, we review the uses of brimonidine in different aspects of dermatology. We searched keywords including rosacea, erythema, topical brimonidine, dermatology, and skin disease in PubMed, Cochrane, and Google Scholar to collect the related published articles. In a review of 15 articles, we found topical brimonidine improved the facial erythema of rosacea. In addition, it reduced the erythema associated with alcohol flushing syndrome, intense pulsed light therapy, and photodynamic therapy. Furthermore, topical brimonidine was used as a hemostatic agent in dermatosurgery procedures such as Mohs surgery and nail surgery to reduce intra-operative and postoperative bleeding. Some side effects such as erythema, flushing, and burning were reported in a few patients. Based on our findings, brimonidine is a beneficial drug that can be used in various dermatologic disorders with negligible side effects.

Various conditions, including infections, can cause telogen effluvium (TE). One of them is coronavirus disease 2019 (COVID-19), where hair loss usually begins between 2 and 12 weeks after the illness. TE can be acute or chronic, and the chronic type can be intermittent. Here, we present the case of a 17-year-old girl with severe and widespread hair loss following an upper respiratory infection suspected to be COVID-19, with the patient having a history of such attacks since childhood. Evidence from biopsy and dermoscopy indicated a diagnosis of TE.
RESUMO
Scarring is one of the most esthetically challenging and psychologically burdening aspects following inflammatory acne. While "macular" disease is the scar subtype with the least complicated outcome, its phase can be regarded as the most defining in the ultimate scar appearance. Moreover, with lasers recently gaining much popularity in the scientific community for managing several dermatologic conditions, we aimed to evaluate whether they would lead to significant benefits. For this systematic review, four databases consisting of PubMed, Scopus, Embase, and Web of Science were searched using a comprehensive string, with the data from the relevant yet eligible identified records qualitatively synthesized. After investigating the data obtained from the nine included studies, we found the utilized lasers, namely neodymium-doped yttrium aluminum garnet, fractional carbon dioxide, pulsed dye, erbium:glass, pro-yellow, and high-power optically pumped semiconductor, to be highly effective in managing the erythematous or dyspigmented appearance with the reduced elasticity also significantly improving. Moreover, the adverse events were both bearable and minimal, and transient. However, the degree of improvement each type of scar demonstrated following laser therapy varied based on the laser used. Neodymium-doped yttrium aluminum garnet, fractional carbon dioxide, and pulsed dye are the most commonly investigated lasers for managing macular acne scars, demonstrating eye-catching capabilities in managing either erythema or dyspigmentation. However, we still recommend that further comparative interventional studies be carried out, while the intended outcomes also assessed with objective measures for further clarification.

With the investigation of the efficacy of laser therapy in primary localized amyloidosis(PLCA) only recently starting to materialize, we aimed to review the currently available studies of laser therapy in the management of the disease. We searched PubMed, Scopus, Embase, Web of Science, Cochrane, and ProQuest online databases with a specified search strategy, assessed the quality of each study, and then extracted the eligible data. Five RCTs(randomized controlled trials), one non-randomized controlled trial, three case series, and nine case reports(18 in total) were included. Overall, carbon dioxide (CO2), neodymium-doped:yttrium aluminum garnet (Nd:YAG), pulsed dye (PDL), Er (Erbium):YAG, and yttrium/erbium fiber were the studied lasers. One hundred fifty-five cases in total underwent laser therapy, with CO2 being the most frequent laser. Almost all studies demonstrated significantly desirable outcomes, while only mild and transient side effects were noted. Even though the studies' results were significant, we noticed that implementing a consistent methodology and a standardized objective assessment method was missing. Therefore, we recommend that future studies be conducted with less heterogeneous data for a more definite conclusion.

INTRODUCTION: Melasma remains a recurrent, chronic, therapeutically challenging, and psychologically burdening condition. Several different modalities and approaches have been utilized, and some with notable success to experimentally manage the condition. Cysteamines, with their depigmentation properties, have only recently been intensely studied. One such formulation is the topical 5% cysteamine hydrochloride, the structure of which is notably more stable and with a less foul odor than its prior counterparts. We, therefore, aimed to assess the efficacy of the mentioned formulation in the treatment of melasma. METHODS: The PubMed, SCOPUS, ISI Web of Science, and Embase, Cochrane, and Proquest databases were thoroughly searched for English studies evaluating the effects of the topical agent mentioned. RESULTS: Eight studies (five RCTs, two case reports, and one case series) were included after three rounds of screening, most of which were carried out in Iran. Statistical significance was noted when assessing decreased melanin content and satisfaction rates. CONCLUSIONS: It appears that the cysteamine cream could be comparably efficient in treating melasma while accompanied only by minor and transient adverse events. However, current evidence is limited by insufficient sample size, long-term follow-up, and only to epidermal melasma, highlighting the need for appropriately designed randomized controlled clinical trials to draw a conclusive image of the cysteamine's role in treating this recalcitrant condition.

Primary localized cutaneous amyloidosis (PLCA) is a recalcitrant sporadic dermatological condition and most treatments have failed so far. We studied the efficacy of topical dimethyl sulfoxide (DMSO) 50% solution in comparison with tretinoin 0.5% cream in treatment of macular amyloidosis. In this split-side within-person single-blinded randomized clinical trial, 18 patients with bilateral macular amyloidosis received topical DMSO 50% solution and tretinoin 0.5% cream either on their right or the left side. The colorimetry, pruritus scoring, and photography were done. A significant pigmentation decline per each follow-up was observed in DMSO group compared to the tretinoin group (tretinoin: -1.31 vs DMSO: -7.34; difference in slopes: -6.03 [95% confidence interval: -12.06 to -0.01], PInteraction = .049). An insignificant diminution trend in pigmentation was observed for both treatments (Ptretinoin = .672, PDMSO = .092). Also, both treatments relived itchiness, but DMSO completely dispatched itchiness from the first follow-up (P = .003 for tretinoin and <.0001 for DMSO). In conclusion, our results showed DMSO and tretinoin cream have the positive effect on the both pigmentation and itchiness in PLCA. DMSO may be more beneficial than tretinoin, since DMSO was significantly better in reducing itchiness. More investigations are warranted to provide sufficient evidence.
