RESUMO

Trace elements are essential for maintaining the body's homeostasis, and their special role has been demonstrated in skin physiology. Among the most important trace elements are zinc, copper, and iron. A deficiency or excess of trace elements can be associated with an increased risk of skin diseases, so increasing their supplementation or limiting intake can be helpful in dermatological treatment. In addition, determinations of their levels in various types of biological material can be useful as additional tests in dermatological treatment. This paper describes the role of these elements in skin physiology and summarizes data on zinc, copper, and iron in the course of selected, following skin diseases: psoriasis, pemphigus vulgaris, atopic dermatitis, acne vulgaris and seborrheic dermatitis. In addition, this work identifies the potential of trace elements as auxiliary tests in dermatology. According to preliminary studies, abnormal levels of zinc, copper, and iron are observed in many skin diseases and their determinations in serum or hair can be used as auxiliary and prognostic tests in the course of various dermatoses. However, since data for some conditions are conflicting, clearly defining the potential of trace elements as auxiliary tests or elements requiring restriction/supplement requires further research.

RESUMO

Acne vulgaris (AV) is one of the top concerns dermatologists encounter from women. Until now, therapies addressing AV have largely centered around, and have been successful at, targeting the pathophysiological mechanisms that occur at the pilosebaceous unit: sebum hypersecretion, follicular keratinization, over-proliferation of Cutibacterium acnes, and a localized immune response. In addition to these, there is good evidence to suggest that other systemic drivers of a generalized inflammatory response may contribute to the development or exacerbation of acne and that addressing these underlying factors may open more opportunities for developing effective treatments. These include psycho-emotional stress, diet and metabolism, hormonal fluctuations, skin and gut microbiome, oxidative stress, and immune response. While there is accumulating evidence that vitamins, minerals, and botanicals may mitigate some of the pro-inflammatory effects from the activation of these underlying systems, their use and recommendations are limited by a lack of quality efficacy and safety evidence. Here, we present the current evidence for the use of individual supplements in addressing the 6 systemic underlying drivers of AV. We also present a clinical study on the safety and efficacy of a nutraceutical combining many of these ingredients in the management of AV in men and women.  J Drugs Dermatol. 2024;23(3):160-167     doi:10.36849/JDD.8138.

RESUMO

Acne is one of the most common dermatological conditions to affect women of childbearing age, so it is important to consider the safety of long-term acne treatments on women who could become pregnant. In this review article, we clarify what management options are available to treat acne during pregnancy. Topical treatments, typically first-line for acne, such as azelaic acid, clindamycin, erythromycin, metronidazole, benzoyl peroxide, salicylic acid, dapsone, and retinoids, were reviewed. Systemic treatments, such as zinc supplements, cephalexin, cefadroxil, amoxicillin, azithromycin, erythromycin, and corticosteroids, typically second-line for acne, were also reviewed. Alternative treatments such as light therapy and cosmetic procedures were also evaluated. Due to recommendation of sunscreen utilization during acne treatments, sunscreen usage during pregnancy was also assessed. Management of acne during unplanned pregnancy was discussed in further detail regarding safety and adverse effects. Through summarized tables and examples of studies demonstrating safety and efficacy of treatments, the following is a resource for providers and patients to utilize for management of acne during pregnancy.

RESUMO

Acne vulgaris is one of the most common skin diseases worldwide and causes great distress to patients. In addition, most acne patients suffer from low self-esteem and social withdrawal. This study aimed to assess the prevalence of acne and its impact on quality of life among medical students. It also evaluates the patterns of self-treatment use. The study population consisted of all medical students from An-Najah National University (ANU) and the hospital. The questionnaire consists of three parts, and the first part consists of questions regarding demographic information. The second part consisted of questions to measure the severity of acne using the acne severity scale as well as the Cardiff Disability Index, which assesses the quality of life concerning acne in medical students. Finally, the third part consisted of questions exploring and assessing acne self-treatment. The mean age of our study sample was 21.3 ± 1.9 years, with a female predominance of 72.3%. The prevalence of acne among medical students was 80.9%, and 36.6% practiced self-medication. Acne was strongly associated with female sex (p < 0.001) and skin type (p = 0.024). Regarding diet, dairy consumption (p = 0.007), sweets (p < 0.001), chocolate (p < 0.001), and oily food (p = 0.006) were all significantly associated with acne. Skin type was strongly associated with the severity of acne (p < 0.001) and the Cardiff acne disability index (p = 0.016). Gender (p = 0.039) was also associated with Cardiff acne disability. A significant correlation was found between the severity of acne and impaired quality of life. The most commonly used topical agent for self-treatment remedies was antibiotics (70.3%). The most commonly used oral agent was isotretinoin (9.4%). A total of 22.7% of the students used herbal products, while 47.7% used home remedies. Acne is prevalent among medical students, with a high percentage of students having different degrees of impairment in their daily lives. As a result, self-medication among acne sufferers is highly common. Awareness of the appropriate use of self-medication should increase among medical students.

RESUMO

BACKGROUND: Since general practitioners manage acne-related referrals, there needs to be more information in Iran about how drugs such as Isotretinoin are prescribed and the treatment plan. Thus, this study aimed to evaluate general practitioners s' practices and attitudes in prescribing Isotretinoin for acne vulgaris in primary care. METHODS: This web-based cross-sectional descriptive study was conducted using two questionnaires designed with the target population of GPs working in Fars province in 2021 regarding the prescription of Isotretinoin. Moreover, demographic information, questions about interest in dermatology, and participation in dermatology workshops were gathered. RESULTS: A total of 308 complete questionnaires were obtained. According to our results, 85 (27.6%) GPs prescribed Isotretinoin in primary care. Based on our results, higher age (OR: 1.042; CI95%: 1.013-1.072; P-value:0.004) and attending dermatological courses (OR: 3.280; CI95%: 1.592-6.755; P-value:0.001) were significantly correlated with more frequent Isotretinoin administration. Among GPs who do not prescribe Isotretinoin, the most common causes are concerns about liver dysfunction (54.7%), teratogenic concerns (37.2%), and lack of familiarity with the drug (31.4%) respectively. CONCLUSION: The results of this study depicted the reluctance of most physicians to prescribe Isotretinoin and factors such as taking part in supplementary courses under the supervision of dermatologists and following national guidelines that could encourage them to prescribe Isotretinoin.

RESUMO

BACKGROUND: Comedone extraction provides greater satisfaction for acne treatment than conventional treatment alone; however, post-comedone extraction erythema (PCEE) remains a concern for patients. OBJECTIVES: To evaluate the efficacy of pulsed-dye laser (PDL) in PCEE and comedone reduction. METHODS: Mild-to-moderate acne patients were randomly allocated in split-face fashion. Three comedones were extracted on each facial side. On the PDL-treated side, 595-nm PDL was delivered to the entire side with an additional shot on three comedone-extracted sites. Erythema index (EI) and total acne lesion counts (TALC) were evaluated at baseline, week 2 and 4. The comprehensive acne severity scale (CASS) was assessed by three blinded independent pediatric dermatologists. Participant satisfaction surveys were completed at the end of the study. RESULTS: Thirty-five participants (age 12.9-24.2 years) showed no differences in the EI and TALC at baseline on both sides. At weeks 2 and 4, the EI on the PDL-treated side was significantly lower (p < 0.001) with a greater EI reduction (p < 0.001) when compared to the control side regardless of gender and menstruation. There was significantly lower TALC on the PDL-treated side at week 2 (p < 0.001) and week 4 (p = 0.02). No complications were noted with high participant satisfaction reported (median 8; IQR 7-9). PDL remained significantly associated with EI improvements after controlling for gender, menstruation cycle, and examination stress. CONCLUSION: PDL can be an adjunctive intervention for the treatment of PCEE and comedone reduction due to its effectiveness and high participant satisfaction.

RESUMO

BACKGROUND: Acne vulgaris (AV) is a prevalent skin condition known for its potential to cause scarring and psychological distress, often leading to diminished self-esteem. While topical and oral treatments are commonly prescribed, some patients experience treatment failure, adverse effects, or contraindications to conventional therapies. In response to these challenges, laser and energy-based device therapies have emerged as promising alternatives for individuals who fall into these categories, showing considerable potential in the treatment of AV. OBJECTIVE: This study aimed to evaluate the long-term efficacy and safety of a nonablative monopolar radiofrequency (NMRF) in treatment of moderate to severe AV. METHODS: Twenty-four patients with moderate to severe AV underwent a series of two NMRF treatment sessions, spaced 4 weeks apart. To evaluate treatment outcomes, live in-person lesion counts and measurements of pore size and volume, and sebum production were quantified using Antera® 3D imaging system, and Sebumeter®, respectively. Patients' self-assessment data regarding degree of improvement and facial oiliness were gathered. Dermatology life quality index (DLQI) questionnaire was utilized to assess the impact of AV on their quality of life. All objective and subjective evaluations were conducted at the baseline, 1 month after the first treatment, and during follow-up visits 1, 3, and 6 months after the last treatment sessions. Adverse effects were also recorded during each visit. RESULTS: Twenty out of the 24 subjects completed the study protocol. The mean inflammatory lesion counts significantly reduced by 42.86% and 45.71% from the baseline at 3 (p = 0.027) and 6 months (p = 0.032) after the second treatment. Sebum excretion likewise significantly decreased from baseline by 11.62% (p = 0.012), 13.37% (p < 0.001), and 21.51% (p = 0.004), 1 month after the first treatment, 1 and 6 months after the second treatment, respectively. The pore volume continued to decrease by 35% (p = 0.003) and 41.5% (p < 0.001) at 1 and 6 months following the final treatment, respectively. The DLQI significantly decreased from 10.00 (interquartile range [IQR]: 6.50-15.00) to 2.00 (IQR: 1.00-4.75), corresponding to 80% improvement of the index, 1 month after the last treatment and was sustained up to the last follow-up visit. Patients' self-assessments on degree of improvement and facial oiliness also significantly improved following NMRF treatments. The treatments were well-tolerated without significant adverse effects. CONCLUSION: NMRF appears to be an effective and safe treatment for inflammatory AV, with therapeutic outcomes persisting up to 6 months after two treatment sessions.

RESUMO

Objectives:We aimed to explore the potential role of omega-3 (ω-3) fatty acids on acne vulgaris by modulating gut microbiota.Materials and Methods:We randomly divided the untreated acne patients into two groups with or without ω-3 fatty acids intervention for 12 weeks. The Sprague Dawley (SD) rats with acne model were given isotretinoin, ω-3 fatty acids or their combination respectively. Then the colonic contents samples of the drug intervention SD rats were transferred to the pseudo sterile rats with acne model. The severity of the disease was assessed by the Global Acne Grading System (GAGS) score of the patients, and the swelling rate of auricle and the pathological section of the rat with acne model. The 16S rDNA gene sequencing was performed to detect the alteration of the gut microbiota.Results:ω-3 fatty acids could increase the diversity of the gut microbiota and regulate the flora structure positively both in the patients and rats, increase the abundance of butyric acid producing bacteria and GAGS score in the patients, and alleviate the inflammation and comedones of rats.Conclusion:Supplementation of ω-3 fatty acids could alleviate the inflammation of acne vulgaris by increasing the abundance of butyric acid producing bacteria.

RESUMO

Antibiotics have constituted the mainstay of acne therapy despite acne being classified as an inflammatory disorder. The indiscriminate usage of antibiotics over the years has thus fueled the issue of antimicrobial resistance. Cutibacterium acnes (C. acnes) can acquire resistance due to chromosomal mutation or genetic acquisition. C. acnes can transfer resistance to other resident flora, complicating the management of skin and soft tissue infections. It can also transfer resistant strains to other body sites and to immunocompromised and elderly patients thus putting them at risk of serious infections. Recent studies have highlighted the physiologic role of C. acnes in maintaining the normal homeostasis of the skin microbiome. The role of Malassezia in causation of acne has piqued interest in recent times. The efficacy of antibiotics in acne is attributed to their para-antibiotic, anti-inflammatory action rather than antimicrobial action. Thus, usage of low-dose antibiotics and alternatives to antibiotics has been advocated. Some alternative therapies showing efficacy in acne are probiotics, oral zinc, precision therapy using succinic acid, bacteriophages, and anti-biofilm therapy like myrtacin, topical azelaic acid, and salicylic acid. Using isotretinoin in early stages of acne can reduce the incidence of scarring and alleviate the need for antibiotics. Thus, a gradual shift from antibiotics to alternative therapies in acne is the need of the hour.

RESUMO

OBJECTIVE: To evaluate the effectiveness and safety of Curcumin-mediated Photodynamic Therapy (Curcumin-PDT) in the treatment of mild to moderate acne. METHODS: In this randomized split-face controlled study, 11 patients with mild to moderate acne were randomly divided into two groups. One side received a single 445 nm LED light exposure of 36 J/cm2, while the other side received Curcumin-PDT. The process of Curcumin-PDT involves the application of a mask containing 1 % curcumin for 20 min, followed by exposure to 445 nm LED light at 36 J/cm². The treatment consists of sessions spaced every 3 days, with a total of 2 treatments per week, administered continuously for 2 weeks. Efficacy assessment and comparison were conducted on both groups of patients before treatment and 2 weeks after the last treatment, and adverse reactions were observed and recorded. RESULTS: At the 2-week follow-up after the last treatment, the total lesion clearance rates for Curcumin-PDT and monotherapy light were 54.7 ± 21.5 % and 28.1 ± 19.9 %, respectively (P = 0.001). The clearance rates for non-inflammatory lesions were 32.3 ± 25.7 % and 21.9 ± 14.0 % for Curcumin-PDT and monotherapy light sides (P = 0.252), while for inflammatory lesions, the clearance rates were 59.3 ± 28.2 % and 36.5 ± 21.6 % (P = 0.013). Both groups experienced mild erythema after treatment, which subsided within 1-2 h. Two patients developed mild localized pigmentation, which self-resolved after 1 month of follow-up. Both groups did not exhibit edema, crust formation, scaling, pigment reduction, or scarring. CONCLUSION: Curcumin-PDT can be considered a safe and effective method for the treatment of mild to moderate acne.

RESUMO

BACKGROUND: Acne vulgaris is a common dermatological condition that greatly impacts patients' self-confidence. Ongoing research is conducted to explore new treatment modalities. Silymarin owns special characteristics that qualify it as a possible treatment for acne vulgaris. OBJECTIVE: We evaluated the efficacy and safety of silymarin cream as a new therapeutic option against salicylic acid peels in the treatment of mild to moderate acne vulgaris. METHODS: A split-face, comparative, Quasi-experimental clinical trial included 30 patients with acne vulgaris. Salicylic acid 30% peels were applied as an office procedure to one half of the face every 2 weeks for 3 months. Topical silymarin 1.4% cream was prescribed as a home treatment, twice daily, to the other half of the face for 3 months. The results were evaluated using the Global Acne Grading System (GAGS), photographic evaluation, and patient self-assessment scale. The adverse effects during treatment were recorded. The sample size was calculated by Stata/IC 16.1. RESULTS: After treatment, a significant reduction of GAGS was noted on both sides of the face, with an insignificant difference between both treatments. The comparative photographic evaluation and patient self-assessment scale were also insignificant. Hyperpigmentation was recorded in 2 cases on the salicylic acid-treated side. No side effects for silymarin cream were observed. CONCLUSION: Topical silymarin cream 1.4% showed comparable results to Salicylic acid 30% peels. It can be considered a promising safe treatment modality for mild to moderate acne vulgaris.

RESUMO

BACKGROUND: The treatment of acne vulgaris is often challenging due to the antibiotic resistance frequently observed in Cutibacterium acnes (C.acnes), a prevalent bacterium linked to this condition. OBJECTIVE: The objective of this research was to examine the impact of curcumin photodynamic therapy (PDT) on the survival of C.acnes and activity of biofilms produced by this microorganism. METHODS: Following the Clinical and Laboratory Standards Institute (CLSI) guidelines, we assessed the drug sensitivity of 25 clinical C.acnes strains to five antibiotics (erythromycin, clindamycin, tetracycline, doxycycline, minocycline) and curcumin by implementing the broth microdilution technique. In addition, we established C.acnes biofilms in a laboratory setting and subjected them to curcumin-PDT(curcumin combined with blue light of 180 J/cm2). Afterwards, we evaluated their viability using the XTT assay and observed them using confocal laser scanning microscopy. RESULTS: The result revealed varying resistance rates among the tested antibiotics and curcumin, with erythromycin, clindamycin, tetracycline, doxycycline, minocycline, and curcumin exhibiting resistance rates of 72 %, 44 %, 36 %, 28 %, 0 %, and 100 %, respectively. In the curcumin-PDT inhibition tests against four representative antibiotic-resistant strains, it was found that the survival rate of all strains of planktonic C. acnes was reduced, and the higher the concentration of curcumin, the lower the survival rate. Furthermore, in the biofilm inhibition tests, the vitality and three-dimensional structure of the biofilms were disrupted, and the inhibitory effect became more significant with higher concentrations of curcumin. CONCLUSION: The results emphasize the possibility of using curcumin PDT as an alternative approach for the treatment of C.acnes, especially in instances of antibiotic-resistant variations and infections related to biofilms.

RESUMO

OBJECTIVE: Isotretinoin is the only medication against all the factors involved in acne vulgaris pathogenesis. The aim of our study was to verify whether patients with acne vulgaris receiving isotretinoin therapy exhibit elevated anger levels and to observe the correlation between age, temperament traits, and anger. METHODS: The study group comprised a sum of 100 cases, involving 50 individuals with acne vulgaris-required high-dose retinol therapy and 50 controls who did not start any medication. RESULTS: Our study showed that anger levels increased with drug use. A positive correlation between cyclothymic temperament, the anxiety-related behavior subdimension, and the introvert and passive-aggressive subdimension of interpersonal anger reactions has been recognized. In addition, a positive one was observed between hyperthymic temperament and the introvert subdimension, which is one of the anger-related thoughts and interpersonal anger reactions. CONCLUSION: This study elucidates anger dimensions such as anger-related thoughts, behaviors, and reactions in individuals who received retinol treatment for acne vulgaris. In addition to anger and its dimensions, temperament was also investigated. Although several studies have investigated the relationship between acne vulgaris and psychiatric symptoms, to the best of our knowledge, no research has been reported in the English-language literature regarding the relationship between anger dimensions and temperament after retinol treatment that might make our study an original and valuable contribution to the literature.

RESUMO

OBJECTIVES: To compare the effects of 2 Hz continuous wave and 2 Hz/100 Hz dilatational wave setting in electroacupuncture(EA) on ovulation frequency, hormone levels, body fat parameters, quality of life and depression-anxiety level in polycystic ovary syndrome (PCOS) patients with abdominal obesity. METHODS: PCOS patients with abdominal obesity were randomly divided into low-frequency group (n=29) and dilatational wave group (n=29). Patients in both groups were treated with "Tongtiaodaimai" (regulating Dai Meridian) acupuncture therapy, and EA was applied to bilateral Daimai (GB26), Tianshu (ST25), Shenshu (BL23) and Ciliao (BL32). The low-frequency group received EA using a continuous wave at a frequency of 2 Hz, while the dilatational wave group received dilatational wave at a frequency of 2 Hz/100 Hz. Both groups received treatment for 30 min each time, 3 times per week for 12 consecutive weeks. Ovulation frequency was calculated according to the ovulation cycle. The contents of serum anti-Mullerian hormone (AMH) and sex hormone binding globulin (SHBG) were detected with electrochemiluminescence method. Body weight (BW) and waist circumference (WC) were measured, and body mass index (BMI) and waist-height ratio (WHtR) were calculated. PCOS questionnaire (Chi-PCOSQ), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were evaluated. RESULTS: Compared with before treatment, both the low-frequency group and the dilatational wave group showed an increase in ovulation frequency (P<0.01, P<0.05), and a decrease in BW, BMI, WC, WHtR, and SDS score (P<0.01, P<0.05);the dilatational wave group showed decreased serum AMH contents (P<0.05) and increased serum SHBG contents (P<0.05), the scores related to acne, fatigue, and dysmenorrhea in the Chi-PCOSQ increased (P<0.01, P<0.05). Compared with the low-frequency group, the dilatational wave group showed a reduction (P<0.05) in WC after treatment. CONCLUSIONS: 2 Hz/100 Hz dilatational wave EA is equally effective as 2 Hz low-frequency EA in improving ovulation frequency. In terms of reducing WC in abdominal obesity type PCOS patients, 2 Hz/100 Hz dilatational wave EA is superior to 2 Hz low-frequency EA. 2 Hz/100 Hz dilatational wave EA can decrease serum AMH, increase serum SHBG, and improve symptoms of acne, fatigue, and dysmenorrhea.

RESUMO

Acne vulgaris is an inflammatory skin condition that affects virtually everyone at some point. Papules, comedones, pustules, scarring, and nodules are standard features of the disease and can have a detrimental social and psychological impact on an individual. Although allopathic acne treatments are available, they have adverse side effects, are expensive, and are prone to cause antibiotic resistance. The present study is aimed at formulating and evaluating topical gels containing Aloe vera, Allium cepa, and Eucalyptus globulus extracts as potential antiacne drugs. Six formulations containing the herbal extracts were prepared using 1% Carbopol 940 as a gelling agent. The phytochemical composition of the plant extracts was determined. The extracts and gels' minimum inhibitory concentration (MIC) was assessed using the microbroth dilution method. The physicochemical properties of the formulated gels, such as homogeneity, colour, texture, odour, grittiness, spreadability, extrudability, viscosity, pH, and drug content, were evaluated. All the plant extracts contained alkaloids, flavonoids, tannins, triterpenoids, and coumarins. The gel formulations showed varying activity against Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, Candida albicans, and Pseudomonas aeruginosa at various concentrations. The phytochemical components of the plant extracts are probably responsible for the antimicrobial activity of the gel formulations. The 5% Aloe vera-Allium cepa (1 : 1) combination gel formulation showed excellent activity against Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans, with MICs of 12.50, 25.00, 6.25, 25.00, and 12.50 mg/mL, respectively. The gels generally had good physicochemical and antimicrobial properties and could be used as antiacne remedies.

RESUMO

The incidence of acne is on the rise due to unhealthy diet and living habits. Jinhuang ointment (JHO) is a classic prescription composed of 10 kinds of commonly used Chinese herbal medicine, which has been widely used in clinical prevention and treatment of skin inflammatory diseases since ancient times. However, the pharmacological mechanism and target of JHO are not clear. The acne microarray dataset was downloaded from gene expression omnibus database to identify differentially expressed genes (DEG). Immune infiltration was analyzed by CiberSort algorithm. HUB gene was identified by protein-protein interaction network. The gene expression omnibus dataset validates the biomarkers of acne with high diagnostic value. The potential active components and targets of JHO were obtained through Traditional Chinese Medicine Systems Pharmacology database, and the therapeutic targets were obtained by crossing with disease targets. R-packet is used for enrichment analysis. Molecular docking using Auto Dock Tools. A total of 202 DEGs were identified from 12 skin samples in the GSE6475. Immune infiltration analysis showed that there were a large number of macrophages and mast cells in acne skin. Gene set enrichment analysis analysis showed that DEGS was mainly involved in bacterial reaction, inflammatory reaction and so on. Six central genes and gene cluster modules were identified by Cytoscape software. A total of 185 JHO active components and 220 targets were obtained, of which 10 targets were potential targets for JHO in the treatment of acne. Kyoto encyclopedia of genes and genomes enrichment analysis showed that JHO treatment of acne was mainly related to Toll-like receptors, IL-17 and other signal pathways. The results of molecular docking showed that 5 active compounds in JHO had strong binding activity to the core protein receptor. IL-1 ß, CXCL8, toll-like receptor 2, CXCL2, LCN2, and secretory phosphoprotein 1 may be potential biomarkers for early diagnosis of acne. JHO active components may regulate skin cell metabolism and inflammatory response and improve cellular immune microenvironment by acting on core targets (CXCL8, ESR1, IL-1 ß, MMP1, MMP3, secretory phosphoprotein 1), thus achieving the purpose of treating acne. This is the result of the joint action of multiple targets and multiple pathways. It provides an idea for the development of a new combination of drugs for the treatment of acne.

RESUMO

Phototherapy, encompassing the utilization of both natural and artificial light, has emerged as a dependable and non-invasive strategy for addressing a diverse range of illnesses, diseases, and infections. This therapeutic approach, primarily known for its efficacy in treating skin infections, such as herpes and acne lesions, involves the synergistic use of specific light wavelengths and photosensitizers, like methylene blue. Photodynamic therapy, as it is termed, relies on the generation of antimicrobial reactive oxygen species (ROS) through the interaction between light and externally applied photosensitizers. Recent research, however, has highlighted the intrinsic antimicrobial properties of light itself, marking a paradigm shift in focus from exogenous agents to the inherent photosensitivity of molecules found naturally within pathogens. Chemical analyses have identified specific organic molecular structures and systems, including protoporphyrins and conjugated C=C bonds, as pivotal components in molecular photosensitivity. Given the prevalence of these systems in organic life forms, there is an urgent need to investigate the potential impact of phototherapy on individual molecules expressed within pathogens and discern their contributions to the antimicrobial effects of light. This review delves into the recently unveiled key molecular targets of phototherapy, offering insights into their potential downstream implications and therapeutic applications. By shedding light on these fundamental molecular mechanisms, we aim to advance our understanding of phototherapy's broader therapeutic potential and contribute to the development of innovative treatments for a wide array of microbial infections and diseases.

RESUMO

Acne vulgaris (AV) is a psychosomatic disorder and can negatively affect individuals, especially in terms of psychological well-being, self-esteem, and quality of life (QoL). The current study aimed to investigate the association between AV and psychological health, as well as the influence of acne and psychological distress in predicting patients' self-esteem and QoL. This cross-sectional study included 150 patients clinically diagnosed with AV. The severity of acne was measured using GAGS, and following that, patients were instructed to complete the following forms: DASS-21, RSES, CADI, DLQI, and WHOQoL. Female AV patients had significantly higher depression (p = 0.003, t = 3.025) and anxiety (p < 0.001, t = 3.683). Pearson's correlation analysis indicated a strong, positive, and significant correlation between having acne and experiencing depression (r = 0.630), anxiety (r = 0.661), and stress (r = 0.758) (p < 0.001). Multiple regression analysis suggested acne and associated psychological distress had a significant and negative impact on the patient's self-esteem and quality of life. This study highlights the multifaceted consequences of AV and the need to manage its psychological distress. It emphasizes the need for holistic patient care that addresses acne's physical and emotional aspects, with the ultimate goal of enhancing well-being and QoL.

RESUMO

Zinc oxide nanoparticles have high levels of biocompatibility, a low impact on environmental contamination, and suitable to be used as an ingredient for environmentally friendly skincare products. In this study, biogenically synthesized zinc oxide nanoparticles using Dendrobium anosum are used as a reducing and capping agent for topical anti-acne nanogels, and the antimicrobial effect of the nanogel is assessed on Cutibacterium acne and Staphylococcus aureus. Dendrobium anosmum leaf extract was examined for the presence of secondary metabolites and its total amount of phenolic and flavonoid content was determined. Both the biogenically and chemogenic-synthesized zinc oxide nanoparticles were compared using UV-Visible spectrophotometer, FE-SEM, XRD, and FTIR. To produce the topical nanogel, the biogenic and chemogenic zinc oxide nanoparticles were mixed with a carbomer and hydroxypropyl-methyl cellulose (HPMC) polymer. The mixtures were then tested for physical and chemical characteristics. To assess their anti-acne effectiveness, the mixtures were tested against C. acne and S. aureus. The biogenic zinc oxide nanoparticles have particle sizes of 20 nm and a high-phase purity. In comparison to chemogenic nanoparticles, the hydrogels with biogenically synthesized nanoparticles was more effective against Gram-positive bacteria. Through this study, the hybrid nanogels was proven to be effective against the microbes that cause acne and to be potentially used as a green product against skin infections.
