Abstract
In recent years, there has been a growing interest in traditional medicinal practices such as Ayurveda, which emphasizes the use of natural ingredients for various therapeutic purposes. Vegetable oils are an integral part of our diet and have several applications in the cosmetics and healthcare industries. These oils have also been prescribed in ancient Ayurveda texts to treat various health problems. Ayurveda prescribes a processing technique called 'Murchana' to improve the therapeutic nature of the oils. Spectroscopic techniques have been used for quality assessment in many fields. High sensitivity and a low detection rate make spectroscopy a formidable analytical technique. This study focusses on the spectroscopic analysis of sesame and mustard oils prepared using the ayurvedic processing method 'Murchana'. Spectroscopic analysis techniques including UV-Vis absorbance spectroscopy, fluorescence spectroscopy, and FTIR spectroscopy were employed to study the oils. Origin software was used to plot graphs of the spectra. The results indicated that the murchana process may reduce the components of the oil responsible for its oxidation, thereby increasing the shelf life of the oils. However, further investigations, including other spectroscopy and chromatography techniques, will prove beneficial in ascertaining the effects of the murchana process on vegetable oils. The study's findings also suggest that spectroscopic techniques can be used to supplement chemical techniques to investigate the characteristics of vegetable oils.

Karamanlioglu M, Yesilkir-Baydar S. Characterization of gelatin-based wound dressing biomaterials containing increasing coconut oil concentrations. JOURNAL OF BIOMATERIALS SCIENCE. POLYMER EDITION 2024; 35:16-44. [PMID: 37773094 DOI: 10.1080/09205063.2023.2265624] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Accepted: 09/22/2023] [Indexed: 09/30/2023]
Abstract
This study determined the influence and ideal ratios of various coconut oil (CO) amounts in gelatin (G) based-films as wound dressings since there are limited comparative studies to evaluate the sole effect of increasing CO on protein-based biomaterials. Homogenous films at G:CO ratio of 4:0,4:2,4:3,4:4 (w:w) corresponding to CO-0, CO-2, CO-3, CO-4, respectively, were obtained using solution casting. SEM showed CO caused rougher surfaces decreasing mechanical strength. However, no pores were observed in CO-4 due to bigger clusters of oil improving stretchability compared to CO-3; and durability since aging of CO-4 was >10% lower than CO-0 in aqueous media. FTIR showed triglycerides' band only in CO films with increasing amplitude. Moreover, amide-I of CO-2 was involved in more hydrogen bonding, therefore, CO-2 had the highest melt-like transition temperatures (Tmax) at ∼163 °C while others' were at ∼133 °C; and had more ideal mechanical properties among CO films. XTT showed that increased CO improved 3T3 cell viability as CO-0 significantly decreased viability at 10,50,75,100 μg/mL (p < 0.05), whereas CO-2 and CO-3 within 5-75 μg/mL and CO-4 within 5-100 μg/mL range increased viability ≥100% suggesting proliferation. All CO samples at 25 μg/mL stimulated 3T3 cell migration in Scratch Assay indicating wound healing. CO amounts mainly improved thermal and healing properties of gelatin-based biomaterial. CO-2 was more thermally stable and CO-4 had better influence on cell viability and wound healing than CO-0. Therefore, increased CO ratios, specifically 4:2 and 4:4, G:CO (w:w), in gelatin-based films can be ideal candidates for wound dressing materials.

Abstract
BACKGROUND Literature on emollient use in the management of chronic and recurrent dermatophytosis is limited. OBJECTIVE To assess the efficacy of emollient in the remission maintenance of chronic and recurrent dermatophytosis. METHODS In this randomized open-label study with the intention to treat, 80 patients with chronic recurrent dermatophytosis were randomized into two groups, where both groups were treated adequately for 6 weeks, followed by continuation of topical azole in group A and topical emollient in group B for 6 weeks. Clinical remission was determined by disappearance signs and symptoms of tinea lesions with or without hyperpigmentation. Physician and patient global assessment scores were evaluated every 2 weeks for 6 weeks to assess remission maintenance. RESULTS A total of 80 patients of chronic and recurrent dermatophytosis were assessed for remission maintenance. The recurrence of disease occurred in 20 patients overall, wherein 7 patients (17.5%) in group A and 13 patients (32.5%) in group B at the end of the study (18 weeks); however, the difference between the two groups was not statistically significant (p = .121). The mean physician global assessment scores of group A and group B at 12 weeks were 4.45 ± 0.74 and 4.15 ± 0.92, 4.43 ± 0.90 and 4.10 ± 0.98 at 14 weeks, 4.0 ± 1.32 and 3.98 ± 1.23 at 16 weeks, 3.85 ± 1.44 and 3.90 ± 1.35 at 18 weeks, respectively. The mean patient global assessment scores of group A and group B were 4.65 ± 0.62 and 4.25 ± 0.87 at 12 weeks, 4.40 ± 0.87 and 4.17 ± 0.98 at 14 weeks, 4.18 ± 1.15 and 4.12 ± 1.30 at 16 weeks and 3.97 ± 1.33 and 3.90 ± 1.51 at 18 weeks. CONCLUSION The present study concludes that the efficacy of emollient was not inferior to topical luliconazole for maintaining remission in chronic and recurrent dermatophytosis.

Abstract
Background: Preliminary studies support the use of topical coconut and sunflower seed oil for atopic dermatitis (AD). However, standardized topical formulations of fatty acids from these sources have not been studied. Objective: This study investigates whether coconut oil- and sunflower seed oil-derived isosorbide diesters can be used in conjunction with colloidal oatmeal to improve itch, AD severity, and the need for topical steroids in adults. Methods: This was a single-center, 4-week, randomized, double-blind, and vehicle-controlled study conducted between 2021 and 2022. Thirty-two male and female adults with mild-to-moderate AD were enrolled and completed the study. Participants were randomized to receive either 0.1% colloidal oatmeal (vehicle) or isosorbide diesters (IDEAS, 4% isosorbide dicaprylate and 4% isosorbide disunflowerseedate) along with 0.1% colloidal oatmeal. The main outcomes of the study were changes in the visual analogue rating of itch and 75% improvement in the Eczema Area and Severity Index score (EASI 75) at 4 weeks. Other measures included the use of topical steroids and the relative abundance of skin Staphylococcus aureus. Results: Participants in the IDEAS group had a 65.6% improvement in itch compared with 43.8% in the vehicle group (P = 0.013). In total, 56.5% and 25% of the those in the IDEAS and vehicle groups, respectively, achieved EASI 75 at 4 weeks (P = 0.07). There was no difference in skin hydration or transepidermal water loss. The relative abundance of S. aureus was decreased in the IDEAS group at week 4 compared with no change in the vehicle group (P = 0.044). Topical corticosteroid use increased in the vehicle group compared with a decrease in the IDEAS group at week 1 (292.5% vs 24.8%; P value = 0.039) and week 2 (220% vs 46%; P value = 0.08). Conclusions: Topical application of emollients containing coconut oil- and sunflower seed oil-derived fatty esters may improve itch, reduce topical steroid use, and reduce the relative abundance of S. aureus in mild-to-moderate AD. CTR number: NCT04831892.

A comparative evaluation of low-field and high-field NMR untargeted analysis: Authentication of virgin coconut oil adulterated with refined coconut oil as a case study. Anal Chim Acta 2023; 1273:341537.

Abstract
Despite the advances in low-field nuclear magnetic resonance (NMR), there are limited spectroscopic applications for untargeted analysis and metabolomics. To evaluate its potential, we combined high-field and low-field NMR with chemometrics for the differentiation between virgin and refined coconut oil and for the detection of adulteration in blended samples. Although low-field NMR has less spectral resolution and sensitivity compared to high-field NMR, it was still able to achieve a differentiation between virgin and refined coconut oils, as well as between virgin coconut oil and blends, using principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA), and random forest techniques. These techniques were not able to distinguish between blends with different levels of adulteration; however, partial least squares regression (PLSR) enabled the quantification of adulteration levels for both NMR approaches. Given the significant benefits of low-field NMR, including economic and user-friendly analysis and fitting in an industrial environment, this study establishes the proof of concept for its utilization in the challenging scenario of coconut oil authentication. Also, this method has the potential to be used for other similar applications that involve untargeted analysis.

Abstract
Atopic dermatitis (AD) is the most common chronic inflammatory skin disease. Recent studies have revealed that interactions between pathogenic microorganisms, which have a tendency to parasitize the skin of AD patients, play a significant role in the progression of the disease. Furthermore, specific species of commensal bacteria in the human intestinal tract can have a profound impact on the immune system by promoting inflammation and pruritogenesis in AD, while also regulating adaptive immunity. Natural products (NPs) have emerged as promising agents for the treatment of various diseases. Consequently, there is growing interest in utilizing natural products as a novel therapeutic approach for managing AD, with a focus on modulating both skin and gut microbiota. In this review, we discuss the mechanisms and interplay between the skin and gut microbiota in relation to AD. Additionally, we provide a comprehensive overview of recent clinical and fundamental research on NPs targeting the skin and gut microbiota for AD treatment. We anticipate that our work will contribute to the future development of NPs and facilitate research on microbial mechanisms, based on the efficacy of NPs in treating AD.

Abstract
This study investigates the in vitro antibacterial activity of coconut oil on selected clinical and pure bacterial isolates. Clinical samples were isolated from the people of Ras Al Khaimah, United Arab Emirates. Biochemical examination of the microorganisms was done according to standard methods. Pure bacterial cultures were provided from LTA srl Italia. In this research work, an effort has been made to highlight the valuable properties of Cocos nucifera oil, in order to rationalize the use of coconut oil against bacteria. Experiments were performed by agar well diffusion method. Ciprofloxacin was used as a standard antibiotic. The assay of antibacterial activity of clinical isolate of Streptococcus species showed the highest susceptibility to coconut oil while Escherichia coli had the least. This study endorses the use of coconut oil as therapeutic agent since it contains lauric acid which is bactericidal. The utilization of coconut oil should be promoted as a functional food and the use of coconut seed flesh in our diets should be encouraged for health-supporting functions. Further studies should be done on the oil and its derivatives both in vitro and in vivo to unveil their mechanism of action.

Abstract
BACKGROUND Atopic dermatitis is a common chronic, relapsing, and remitting inflammatory skin disorder associated with cutaneous dysbiosis. Current treatment options often fail to adequately control the disease and have unfavorable safety profiles. There is a need for new options that address these treatment shortcomings. OBJECTIVE The aim of the study was to evaluate the efficacy, safety, and tolerability of FB-401, a live therapeutic product of 3 strains of Roseomonas mucosa, compared to matching placebo applied topically 3 times per week to participants ages ≥2 years of age with mild-to-moderate atopic dermatitis. METHODS A randomized, double-blind, placebo-controlled, parallel-group study was conducted. The primary outcome was the proportion of participants with 50% improvement in Eczema Area and Severity Index score from baseline at week 16. 154 subjects aged 2 or older with a clinical diagnosis of atopic dermatitis as defined by Hanifin and Rajka criteria with mild or moderate severity were randomized 1:1 via interactive web response system to FB-401 or placebo. RESULTS The proportion of subjects who achieved the primary outcome was similar between both treatment groups, with no significant treatment group differences observed at any post-baseline visit. The number of treatment-emergent adverse events and the number of subjects with at least one were similar across treatment groups. One serious adverse event not related to treatment was reported. No treatment-emergent adverse events led to treatment discontinuation or study discontinuation. CONCLUSIONS FB-401 showed an acceptable safety profile but failed to prove superior to placebo in treating children and adults with mild-to-moderate atopic dermatitis.

Burns 2023; 49:365-379. [PMID: 35550830 DOI: 10.1016/j.burns.2022.04.025] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 04/20/2022] [Accepted: 04/24/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND The mainstay of non-invasive scar management, consists of pressure therapy with customized pressure garments often combined with inlays, hydration by means of silicones and/or moisturizers as well as UV protection. It is generally accepted that scar dehydration resulting from impaired barrier function of the stratum corneum and expressed by raised trans epidermal water loss (TEWL) values, can lead to increased fibroblast activity and thereby hypertrophic scar formation. However, we have reached no consensus on exactly what optimal scar hydration is nor on barrier function repair: by means of silicone sheets, liquid silicone gels or moisturizers. Occlusive silicone sheets almost completely prevent TEWL and have been shown to be effective. Nevertheless, many important disadvantages due to excessive occlusion such as difficulties in applying the sheets exceeding 10-12 h, pruritus, irritation, and maceration of the skin are limiting factors for its use. To avoid these complications and to facilitate the application, liquid silicone gels were developed. Despite a reduced occlusion, various studies have shown that the effects are comparable to these of the silicone sheets. However, major limiting factors for general use are the long drying time, the shiny aspect after application, and the high cost especially when used for larger scars. Based on excellent clinical results after using three specific moisturizers for scar treatment in our patients, we wanted to investigate whether these moisturizers induce comparable occlusion and hydration compared to both each other and the widely recognized liquid silicone gels. We wanted to provide a more scientific basis for the kind of moisturizers that can be used as a full-fledged and cost-effective alternative to silicone gel. METHODS A total of 36 healthy volunteers participated in this study. Increased TEWL was created by inducing superficial abrasions by rigorous (20x) skin stripping with Corneofix® adhesive tape in squares of 4 cm². Three moisturizers and a fluid silicone gel were tested: DermaCress, Alhydran, Lipikar and BAP Scar Care silicone gel respectively. TEWL reducing capacities and both absolute (AAH) and cumulative (CAAH) absolute added hydration were assessed using a Tewameter® TM300 and a Corneometer® CM825 at different time points for up to 4 h after application. RESULTS We found an immediate TEWL increase in all the zones that underwent superficial abrasions by stripping. Controls remained stable over time, relative to the ambient condition. The mean percentage reduction (MPR) in TEWL kept increasing over time with Alhydran and DermaCress, reaching a maximum effect 4 h after application. Silicone gel reached maximal MPR almost immediately after application and only declined thereafter. The silicone gel never reached the minimal MPR of Alhydran or DermaCress. Hydration capacity assessed through CAAH as measured by the Corneometer was significantly less with silicone gel compared to the moisturizers. Compared to silicone gel Lipikar provided similar occlusion and the improvement in hydration was highly significant 4 h after application. CONCLUSION Based on the results of both our previous research and this study it is clearly demonstrated that the occlusive and hydrative effect of fluid silicone gel is inferior to the moisturizers used in our center. Lipikar hydrates well but is less suitable for scar treatment due to the lack of occlusion. A well-balanced occlusion and hydration, in this study only provided by Alhydran and DermaCress, suggests that moisturizers can be used as a scar hydration therapy that replaces silicone products, is more cost-effective and has a more patient-friendly application.

Abstract
The bioactivity of the versatile biodegradable biopolymer poly(lactic acid) (PLA) can be obtained by combining it with natural or synthetic compounds. This paper deals with the preparation of bioactive formulations involving the melt processing of PLA loaded with a medicinal plant (sage) and an edible oil (coconut oil), together with an organomodifed montmorillonite nanoclay, and an assessment of the resulting structural, surface, morphological, mechanical, and biological properties of the biocomposites. By modulating the components, the prepared biocomposites show flexibility, both antioxidant and antimicrobial activity, as well as a high degree of cytocompatibility, being capable to induce the cell adherence and proliferation on their surface. Overall, the obtained results suggest that the developed PLA-based biocomposites could potentially be used as bioactive materials in medical applications.

Abstract
OBJECTIVES The aim of this study was to compare the plaque-inhibiting effects of oil pulling therapy with sesame oil or coconut oil using 4-day plaque regrowth study model. METHODS This clinical observer-masked, randomized, crossover designed study involved 24 participants. The participants received professional prophylaxis in the preparatory period and after that subjects started to use the allocated mouthrinse (coconut oil or sesame oil). On day 5, periodontal clinical parameters including plaque index (PI), gingival index (GI), stain index (SI) and bleeding on probing (BOP) were recorded. Subjects underwent a 14-day wash out period and then used the other mouthrinse for 4 days. RESULTS Oil pulling therapy with coconut oil or sesame oil exhibited similar plaque regrowth inhibition (PI = 1.60 ± 0.28 and 1.49 ± 0.22, for oil pulling with coconut oil and sesame oil, respectively) and tooth staining (SI = 0.20 ± 0.11 and 0.21 ± 0.09, for oil pulling with coconut oil and sesame oil, respectively.) In addition, GI and BOP were similar in both groups (GI = 0.61 ± 0.19 and 0.69 ± 0.16; BOP = 0.09 ± 0.24 and 0.03 ± 0.03 for oil pulling with coconut oil and sesame oil, respectively). CONCLUSIONS Oil pulling therapy with coconut or sesame oil showed similar results in terms of plaque regrowth inhibition and tooth staining. According to the present results, both coconut oil and sesame oil can be used for oil pulling therapy with the aim of plaque regrowth inhibition.

Abstract
INTRODUCTION Atopic Dermatitis (AD) is a chronic, recurrent and inflammatory skin disease experienced mostly in childhood. Chronicity of the disease, relapses, constant need of regular skin care causes seeking for alternative treatments. AIM The aim of this study is to evaluate the complementary and alternative treatments (CAT) used by parents' caregivers in pediatric patients diagnosed with AD, and the association between CAT use and patient characteristics. MATERIALS AND METHODS A questionnaire questioning the sociocultural and demographic characteristics of the family, the clinical findings of the patients, their treatments and CAT applications was recorded. RESULTS 83 patients were included in the study. 68.7% of the patients used at least 1 type of CAT. Vitamins and oils were the most commonly used CATs (48.8% and 47%, respectively) and 73.3% of the patients using CAT continued normal AD treatment while using CAT. The biggest factor affecting CAT choice was the advice of the immediate circle (75%), and 40.6% of the patients stated that they benefited from the complementary therapy. CONCLUSION CATs are widely used in AD. Physicians should know the socio-cultural structure of the region they are in, the CATs used and their side effects, and inform the families.

Abstract
While the chemical composition of vegetable butters and oils has been studied in detail, there is limited knowledge about their mechanisms of action after application on the skin. To understand their dermal effects better, 27 clinical studies evaluating 17 vegetable oils (almond, argan, avocado, borage, coconut, evening primrose, kukui, marula, mustard, neem, olive, rapeseed, sacha inchi, safflower, shea butter, soybean and sunflower oils) were reviewed in this research. The reviewed studies focused on non-affected skin, infant skin, psoriasis, xerosis, UVB-induced erythema, atopic dermatitis, molluscum contagiosum, tungiasis, scars, striae and striae gravidarum. We conclude that in inflammation-affected skin, vegetable oils with a high content of oleic acid, together with the lack of or a low linoleic acid content, may cause additional structural damage of the stratum corneum, while oils high in linoleic acid and saturated fatty acids may express positive effects. Non-affected skin, in contrast, may not react negatively to oils high in oleic acid. However, the frequency and duration of an oil's use must be considered an important factor that may accelerate or enhance the negative effects on the skin's structural integrity.

Abstract
The influence of coconut oil (CO) on a gelatin-based film was investigated when used as a potential wound dressing material. There is limited study on CO in protein-based wound dressing materials. Therefore, in this study a self-supporting, continuous and homogenous CO incorporated gelatin-based film was formulated and obtained by solution casting method. The influence of CO on physicochemical and thermal properties of gelatin-based film was also determined. Moreover, the effect CO in gelatin films on cell viability and cell migration was analysed with a preliminary cell culture study. Homogenous dispersion of 10% (w/w) CO was obtained in films when 3% (v/w) Tween 80, a surfactant, was incorporated to 20% (w/w) plasticized gelatin film forming solution. Effect of CO on gelatin-based film was observed via phase separation by SEM analysis. Water uptake of gelatin film with no CO, GE film; and 10% (w/w) CO incorporated GE film, GE-CO, were 320% and 210%, respectively, after 3 hours in water. FTIR analysis showed triglyceride component of CO and increased hydrogen bonding between NH groups of gelatin in GE-CO films. DSC results suggested a more ordered structure of GE-CO film due to an increase in melt-like transition temperature and melting enthalpy of GE-CO film. CO content also increased cell viability, assessed by XTT Assay since cell viability was approximately 100% when L929 cell culture was incubated with GE-CO of 5-100 μg/mL. Moreover, GE-CO samples within 5-25 μg/mL concentration range, increased proliferation of L929 cells since cell viability was significantly higher than the 100% viable cell culture control (P < 0.05) which is also an indication of efficient healing. However, GE decreased viability of L929 cells significantly at 100-10 μg/mL concentration range (P < 0.05) and were toxic at concentrations of 100, 75 and 50 μg/mL which decreased ∿50% of the viability of the cells. Scratch Assay to assess in vitro wound healing showed cell migration towards scratch after 24 h as an indication of wound healing only in GE-CO samples. This study showed that, CO could efficiently be added to gelatin-based films for preparation of a primary wound dressing biomaterial which is also demonstrated to have a promising wound healing effect for minor wounds.

Abstract
OBJECTIVE Provide a review of atopic dermatitis management, focusing on optimizing topical therapy, creating a stepwise approach for treatment plans, and providing guidance on when to start systemic therapy. DATA SOURCES PubMed search of articles in the English language regarding atopic dermatitis in all ages. STUDY SELECTION Articles on the subject matter were selected and reviewed. RESULTS Topical corticosteroids are the first-line treatment for managing atopic dermatitis. Topical nonsteroidal agents, calcineurin inhibitors, crisaborole, and recently, ruxolitinib, which cause no cutaneous atrophy, are options for reducing the use of topical corticosteroids, including on sensitive sites. Emerging topical agents are in clinical trials. Proactive management, with continued application 2 to 3 times weekly of a midpotency topical corticosteroid or tacrolimus, may maintain control for clear (or almost clear) localized sites of dermatitis that rapidly recur when topical anti-inflammatory medication is stopped. If topical therapy alone cannot control disease and quality of life is impacted, reevaluation to confirm the diagnosis, manage comorbid conditions, address compliance and patient-specific concerns, and optimize topical therapy must be undertaken before deciding to advance to systemic medication. Dupilumab, an interleukin-4 receptor inhibitor, has become first-line systemic therapy given its efficacy and safety, allowing long-term treatment without laboratory monitoring. Other biologics and Janus kinase inhibitors are emerging as alternatives that could eliminate the need for immunosuppressants with their higher risks. CONCLUSION Several options are now available for topical treatment. A stepwise approach is needed to consider alternative therapies and diagnoses before advancing to systemic treatment, but the safety of newer immunomodulators will lower the threshold for more aggressive intervention.

Abstract
Objectives: Virgin coconut oil (VCO) pulling has antimicrobial activity and has been promoted as beneficial to oral health; however, limited information exists on its clinical effectiveness. This study aimed to compare the microbiological effects of VCO with palm oil (PO) pulling when used as an adjunctive oral hygiene care. Materials and Methods: Thirty-six volunteers with gingival inflammation were randomly assigned to start with (1) VCO (test) and (2) PO (control) interventions in a crossover design. Oil pulling was performed for 28 days adjunctively to oral hygiene routine. After a 21-day wash-out period, the participants switched the oil type and restarted the protocol. Plaque samples were collected for microbial culture at baseline, after the first oil pulling period, after washout, and after the second oil pulling period. The total, aerobic, and anaerobic bacteria and Mutans streptococci (MS) counts were recorded. The mean differences between VCO and PO were compared by paired t-test. Results: The number of total, aerobic, or anaerobic bacteria after 28 days of oil pulling was not significantly different from baseline in both PO and VCO groups. However, PO pulling demonstrated a significant reduction from baseline of MS count (P = 0.010), while VCO pulling showed no significant reduction. There was no statistically significant difference in the mean changes of any microbiological parameters between the two treatments. Conclusions: VCO pulling did not show statistically significant superior benefit against plaque bacteria over PO pulling. Using PO pulling as an adjunctive oral hygiene care may reduce the number of MS, but this requires further investigations.

Abstract
Background Complementary and alternative medicine (CAM) treatments are growing in popularity as alternative treatments for common skin conditions. Objectives To perform a systematic review and meta-analysis to determine the tolerability and treatment response to CAM treatments in acne, atopic dermatitis (AD), and psoriasis. Methods PubMed/Medline and Embase databases were searched to identify eligible studies measuring the effects of CAM in acne, AD, and psoriasis. Effect size with 95% confidence interval (CI) was estimated using the random-effect model. Results The search yielded 417 articles; 40 studies met the inclusion criteria. The quantitative results of CAM treatment showed a standard mean difference (SMD) of 3.78 (95% CI [−0.01, 7.57]) and 0.58 (95% CI [−6.99, 8.15]) in the acne total lesion count, a SMD of −0.70 (95% CI [−1.19, −0.21]) in the eczema area and severity index score and a SMD of 0.94 (95% CI [−0.83, 2.71]) in the scoring of atopic dermatitis score for AD, and a SMD of 3.04 (95% CI [−0.35, 6.43]) and 5.16 (95% CI [−0.52, 10.85]) in the Psoriasis Area Severity Index score for psoriasis. Limitations Differences between the study designs, sample sizes, outcome measures, and treatment durations limit the generalizability of data. Conclusions Based on our quantitative findings we conclude that there is insufficient evidence to support the efficacy and the recommendation of CAM for acne, AD, and psoriasis.

Abstract
Background Topical emollient therapy with sunflower seed oil (SSO) reduces risk of sepsis and mortality in very preterm infants in low- or middle-income countries (LMICs). Proposed mechanisms include modulation of skin and possibly gut barrier function. The skin and gut microbiota play important roles in regulating barrier function, but the effects of emollient therapy on these microbiotas are poorly understood. Methods We characterised microbiota structure and diversity with 16S rRNA gene amplicon sequence data and ecological statistics in 20 children with severe acute malnutrition (SAM) aged 2-24 months, at four skin sites and in stool, during a randomised, controlled trial of emollient therapy with SSO in Bangladesh. Microbes associated with therapy were identified with tree-based sparse discriminant analysis. Results The skin microbiota of Bangladeshi children with SAM was highly diverse and displayed significant variation in structure as a function of physical distance between sites. Microbiota structure differed between the study groups (P = 0.005), was more diverse in emollient-treated subjects–including on the forehead which did not receive direct treatment–and changed with each day (P = 0.005) at all skin sites. Overall, Prevotellaceae were the most differentially affected by emollient treatment; several genera within this family became more abundant in the emollient group than in the controls across several skin sites. Gut microbiota structure was associated with sample day (P = 0.045) and subject age (P = 0.045), but was not significantly affected by emollient treatment (P = 0.060). Conclusions Emollient therapy altered the skin microbiota in a consistent and temporally coherent manner. We speculate that therapy with SSO enhances skin barrier function in part through alterations in the microbiota, and through systemic mechanisms. Strategies to strengthen skin and gut barrier function in populations at risk, such as children in LMICs like Bangladesh, might include deliberate manipulation of their skin microbiota.

Abstract
Tungiasis (sand flea disease) is an epidermal parasitic skin disease occurring in resource-limited communities. There is no standard treatment for tungiasis, and available treatment options are scarce. To our knowledge, this is the first systematic review aimed to assess randomised controlled trials (RCTs) investigating interventions for tungiasis. We systematically searched databases including MEDLINE (EBSCOhost), CENTRAL, CINAHL, PubMed, Web of Science, SciELO, LILACS and Embase (Scopus) for RCTs in any language, from inception of the databases until June 12, 2021. RCTs exploring preventive and therapeutic interventions for tungiasis were eligible. We used the revised Cochrane Collaboration's risk of bias tool to assess the risk of bias and Jadad scale to quantify the methodological quality of the RCTs. Of the 1839 identified records, only eight RCTs involving 808 participants were included, and several methodological deficiencies were identified in most of the trials. Trial interventions included: oral drugs niridazole and ivermectin and topical interventions of ivermectin lotion, metrifonate lotion, thiabendazole lotion, thiabendazole ointment, dimeticones (NYDA), and a neem seed and coconut oils-based mixture for treatment and coconut oil-based lotion (Zanzarin) for prevention. The coconut oil-based lotion for prevention and dimeticones for treatment of tungiasis have displayed the most promise. Most of the RCTs included in this study had low methodological quality. There is a clear unmet need for high-quality RCTs examining safe and effective prevention and treatment alternatives of tungiasis in endemic settings.

METHODS A literature search was conducted (1990-2021) in Medline, Embase, CINAHL, Google Scholar, Science Direct, SID, IranDoc, and Magiran databases. From the 102 reviewed articles, 17 articles were selected to be included in the current article. RESULTS Various forms of olive have long been used to accelerate the healing of various wounds and skin damage such as diabetic foot ulcers, atopic dermatitis, diaper dermatitis, episiotomy wound, and nipple ulcer but there are still no credible documents or articles that provide reliable evidence of topical use. CONCLUSION According to the information obtained from the articles reviewed, olive oil appears to be an effective, safe, and available treatment. This study suggests that olive oil is an alternative remedy to minimize the frequent use of chemical-based treatments. More research may be beneficial to reach certainty in terms of curative properties of olive oil in similar or different injuries in different populations.

Abstract
Background Increased frequency of using alcohol‐based hand sanitizers (ABHS) by consumers during COVID times have resulted in increased incidences of skin issues on palms. Objective (1) To quantify skin damage with increased usage frequency of ABHS by consumers and (2) To evaluate Virgin Coconut Oil (VCO) as natural prophylactic agent to counter the adverse effects. Methods In‐home usage study was carried out with 60 volunteers for a 15‐day intervention—Control Group: 6 applications per day of ABHS and Test Group: Overnight VCO use (6–8 drops) followed by 6× usage per day of ABHS. This leg included dermatological evaluation and WHO Self‐Assessment Scale for skin health. Another leg of measurement included non‐invasive instrumental study (Moisture & TEWL Probes, Tape Strip for protein content and IR spectroscopy for protein & lipid content) on forearm of 12 subjects (25–60 years age) with and without VCO application and repeated alcohol exposure. Results In‐home usage study established consumer experiencing skin protective effect of VCO in the context of ABHS onslaught. 25% increase in perceived moisture content was recorded for VCO users, using WHO Self‐Assessment Scale. Instrumental studies confirmed an increase in TEWL and decrease in lipids & protein content. Overnight VCO application resists the extraction which builds up with repeated application. Conclusions Current work provides evidence of compromised hand skin barrier with ABHS daily usage. Overnight VCO application helps prepare the skin for next day alcohol use. Based on the findings, a regimen of overnight VCO application on hands as a natural prophylactic is recommended.

Abstract
Atopic dermatitis (AD) is the long-lasting chronic inflammatory skin condition associated with cutaneous hyper-reactivity and triggered by environmental factors. The attributes of AD include dry skin, pruritus, lichenification and frequent eczematous abrasions. This has a strong heritable aspect and typically occurs with asthma and allergic rhinitis. The complex pathological mechanism behind AD etiology is epidermal barrier destruction resulting in the lack of filaggrin protein that can induce inflammation and T-cell infiltration. T-helper 2 cell-mediated pathways also bear the responsibility of damage to the epidermal barrier. Certain causative factors for AD include microbial imbalance of skin microbiota, immunoglobulin-E-induced sensitization and neuro-inflammation. Numerous beneficial topical and oral treatments have been available to patients and there are even more drugs in the pipeline for the treatment of AD. Topical moisturizers, corticosteroids, anti-inflammatory agents such as calcineurin inhibitors, phototherapy, cAMP-specific 3, 5 half-cyclic phosphodiesterase 4 inhibitors and systemic immunosuppressants are widely available for AD treatments. Different positions and pathways inside the immune system including JAK-STAT, phosphodiesterase 4, aryl hydrocarbon receptor and T-helper 2 cytokines are targeted by above-mentioned drug treatments. Instead of the severe side effects of topical steroids and oral antihistamines, herbal plants and their derived phytoconstituents are commonly used for the treatment of AD. A clear understanding of AD's cellular and molecular pathogenesis through substantial advancement in genetics, skin immunology and psychological factors resulted in advancement of AD management. Therefore, the review highlights the recent advancements in the understanding of clinical features, etiology, pathogenesis, treatment and management and non-adherence to AD treatment.

Abstract
Infections caused by Staphylococcus aureus are a serious global threat, and with the emergence of antibiotic resistance, even more difficult to treat. One of the possible complications in antistaphylococcal therapy represents negative interactions of antibiotics with food. In this study, the in vitro interaction between oxacillin and crude palm seed oil from Astrocaryum vulgare, Cocos nucifera, and Elaeis guineensis against nine strains of S. aureus was determined using the checkerboard method. Lauric acid was identified as a major constituent of all tested oils by gas chromatography. The results showed strong concentration dependent antagonistic interactions between palm oils and oxacillin with values of fractional inhibitory concentrations indices ranging from 4.02 to 8.56 at concentrations equal or higher than 1024 µg/mL of the tested oils. Similarly, lauric acid in combination with oxacillin produced antagonistic action with fractional inhibitory concentration indices ranging from 4.01 to 4.28 at 1024 µg/mL. These findings suggest that interference between oxacillin and palm oils and their constituents can negatively affect the treatment of staphylococcal infections in humans and other animals.

Abstract
Objectives Atopic dermatitis (AD) is a prevalent and chronic, pruritic inflammatory skin condition that can influence all age groups. AD is associated with a poor health-related quality of life. This randomized clinical trial was performed to compare the effectiveness of Olivederma (combination of aloe vera and virgin olive oil) or betamethasone regarding disease severity, quality of life, serum IgE and eosinophil count. Methods Thirty-six AD patients were randomly allocated to topical Olivederma or betamethasone, and were followed for 6 weeks. Results Total SCORAD severity scores showed significant decrease in both groups, while it was more prominent in Olivederma group (64.5% improvement in Olivederma vs. 13.5% improvement in Betamethasone, p-value < 0.001). Quality of life (DLQI questionnaire) of AD patients was significantly improved after 6 weeks treatment with Betamethasone (22.3%, p < 0.001) and Olivederma (60.7%, p-value < 0.001). Olivederma group showed a significantly lower DLQI score in comparison with Betamethasone treated patients after 6 weeks of therapy (p < 0.001). Improvements in eosinophil count and serum IgE was observed. Conclusion In summary, this study shows that Olivederma is superior to topical Betamethasone after 6 weeks of therapy with regard to disease severity, quality of life and eosinophil count.

Abstract
INTRODUCTION The aim of this study was to investigate the effectiveness and safety of emollient preparations in comparison with the emollient ointment containing glycerophosphoinositol salt of choline in patients with atopic dermatitis (AD). METHODS In a 'real-life' study, 300 patients with moderate AD were age-stratified and divided into two groups: patients applying GPI emollient and the comparator. We evaluated the effectiveness of AD treatment using: Eczema Area and Severity Index (EASI), Three Item Severity (TIS), Visual Analogue Scale (VAS) and Four-Item Itch Questionnaire. RESULTS The GPI emollient was superior in reduction AD symptoms in children: VAS (-2.58 ± 0.25), TIS (-2.22 ± 0.22), EASI (-15.27 ± 1.77), and adults: VAS (-2.42 ± 0.19), TIS (-2.22 ± 0.17), EASI (-13.22 ± 1.53), as compared to the other emollient in children: VAS (-0.67 ± 0.19), TIS (0.47 ± 0.19), EASI (-3.71 ± 1.01) and adults: VAS (-0.86 ± 0.09), TIS (0.77 ± 0.09), EASI (-2.95 ± 0.46), p < .001. Similar results were observed in Four Item Itch Questionnaire. CONCLUSION Both emollients showed good safety and tolerance profile and reduced AD symptoms. The GPI emollient seems to be more slightly effective in reducing AD symptoms as compared to the other commercially available emollient.

Abstract
Lebanon has witnessed elevated levels of pollution over the last few years due to increased waste incineration, emissions from vehicles and electricity generators, and mass demonstrations involving the burning of tires. The resultant generation of polycyclic aromatic hydrocarbons (PAHs) from the incomplete combustion of organic materials present in these sources may contaminate various foods including olive oil. Lebanon has a sizeable olive oil industry that is a main pillar of its agricultural sector. In this study, we investigated the occurrence of 16 semi-volatile lipophilic organic pollutants in 25 bottled olive oil brands, marketed in Lebanon, using a solid phase extraction (SPE) method followed by gas chromatography mass spectrometry (GC-MS). PAHs were detected in 60% of brands (41% of samples) where 12% of brands contained traces of probably carcinogenic (Class 2A) compounds and 56% of brands contained traces of possibly carcinogenic (Class 2B) compounds. One brand revealed levels of benzo[a]pyrene of 9.45 μg/kg and 11.9 μg/kg in batches collected over two production dates which are higher than the limit set by the European Commission for benzo[a]pyrene in food (2 μg/kg). The same batches contained a total of 19.3 μg/kg and 26.7 μg/kg of the four PAHs: benzo[a]pyrene, benz[a]anthracene, benzo[b]fluoranthene, and chrysene which also exceeded the limit set by the EC for the combination of these four PAHs in olive oil (10 μg/kg). This study is the first-of-its-kind in Lebanon and emphasizes the need to perform adequate cleanup steps in the manufacturing process in order to reduce the content of carcinogenic PAHs in olive oil.

Abstract
To assess incidence of demodex species, correlate ocular symptomatology, evaluate efficacy of coconut oil as treatment method in all types of blepharitis. 30 patients with anterior & mixed blepharitis, meibomian gland dysfunction & non-specific irritation were enrolled for study. History taken & examined clinically. 2 lashes/lid were sampled & mounted on slides with normal saline & observed under light microscope. Number of mites counted. Patients positive for demodex were treated with coconut oil application over lid margins & reviewed after 3 weeks. Incidence of demodex was 40% & it increased with age. Demodex was commonly associated with meibomian gland dysfunction, non-specific irritation, madarosis, cloudy & toothpaste like meibum quality. Burning sensation and itching were common complaints. At 3rd week, all patients were symptom-free. Mite count dropped by 52.8% but were not eliminated. Demodex infestation is often overlooked but it is associated with about half of blepharitis cases. Hence further evaluation should be considered. Coconut oil is an easily available mode of treatment & helps reduce symptoms and mite counts.

Abstract
BACKGROUND AND RATIONALE Xerosis cutis (also referred to as xeroderma, dry skin, asteatosis) affects more than 10 million individuals in Germany. It is among the most common dermatological diagnoses and a cardinal symptom of many dermatological, internal and neurological diseases. Even though it has been established that basic skin care plays a significant role in the management of patients with xerosis cutis, there are as yet no evidence-based algorithms for diagnosis and treatment. OBJECTIVE The present position paper provides physicians across all specialties with a practical, symptom-based approach to the prevention, diagnosis and treatment of xerosis cutis. METHODS Within a structured decision-making process, a panel of experienced dermatologists first defined questions relevant to everyday clinical practice, which were then addressed by a systematic review of the literature. Based on the evidence available as well as expert consensus, diagnostic and treatment algorithms were subsequently developed and agreed upon. RESULTS Xerosis cutis is generally diagnosed on clinical grounds. Possible trigger factors must be avoided, and comorbidities should be adequately and specifically treated. Suitable skin care products should be chosen with a view to improving skin hydration and restoring its barrier function. They should therefore contain both rehydrating and lipid-replenishing components. The "drier" the skin appears, the greater the lipid content should be (preferably using water-in-oil formulations). The choice of ingredients is based on a patient's individual symptoms, such as scaling (e.g., urea), fissures/rhagades (e.g., urea or dexpanthenol), erythema (e.g., licochalcone A) and pruritus (e.g., polidocanol). Other factors to be considered include the site affected and patient age. Ingredients or rather combinations thereof for which there is good clinical evidence should be preferentially used. The best evidence by far is available for urea, whose efficacy in the treatment of xerosis is further enhanced by combining it with other natural moisturizing components and ceramides. The "xerosimeter" is a tool developed in an effort to facilitate patient management and for training purposes. It not only includes practical tools for diagnosis and follow-up but also a classification of ingredients and a structured treatment algorithm. CONCLUSION The structured symptom- and evidence-based approach proposed herein contains a road map for diagnosis and treatment of xerosis cutis. It aims to raise awareness in terms of prevention and early treatment of this condition and may thus improve quality of life and prevent potential sequelae.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory disease with increasing global incidence, which has a multifactorial pathogenesis and a variable expressivity. Clinical features of AD are different in adults compared to children, but it is well recognized the substantial impact of the disease on patients' quality of life at any age. Indeed, little is known about AD in adolescence, a period of life generally associated with high psychological burden and vulnerability to depression. Guidelines for the management of AD are available for both children and adults but specific guidelines for the diagnosis and treatment of AD in adolescents are lacking. Seven Italian scientific societies of dermatologists, allergists, and pediatric allergists joined in a specific meeting to provide practical guidance for the diagnosis and management of moderate-to-severe adolescent AD suitable for the Italian clinical practice. Through a modified Delphi procedure, consensus was reached by 59 Italian experts in the management of AD on 20 statements covering five areas of interest about adolescent AD, including disease complexity, burden and social impact, diagnosis and definition of severity, current treatments, and new biologic therapies. This paper reports recommendations for the diagnosis and management of AD specifically in adolescents, pointing out some peculiar clinical features and focusing on the choice of medications. Dupilumab, the first biologic approved for the treatment of adolescents with AD, represents a useful treatment option due to its efficacy and reassuring safety profile.

Abstract
: The role of Staphylococcus aureus (SA) in the pathogenesis and management in atopic dermatitis is rapidly evolving. The modern understanding of SA in atopic dermatitis now includes an expanded array of virulence factors, the interplay of clonal and temporal shifts in SA populations, and host factors such as filaggrin and natural moisturizing factor. New, emerging therapies that focus on long-term, targeted elimination of SA colonization are currently under investigation (Br J Dermatol 2017;17(1)63-71). Herein, we discuss and review the latest staphylococcal and microbiome-modifying therapies including topical antibiotics, topical natural oil fatty acids, anti-SA vaccines, microbial transplantation, vitamin D supplementation, dupilumab and proposed future investigative directions.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Indigo naturalis, a herbal medicine with a history of use dating back to ancient times, may be a good alternative topical treatment for atopic dermatitis (AD). AIM OF THE STUDY To provide empirical evidence of the efficacy and safety of Indigo naturalis ointment in treating AD. MATERIALS AND METHODS In this randomized double-blind clinical trial, participants aged 6 to 65 years with AD affecting less than 40% of their body surface area (BSA) and an Investigator's Global Assessment (IGA) score of 2 to 4 were randomized (2:1) to receive either Lindioil ointment or a vehicle ointment twice daily for 6 weeks. The primary endpoint was the percentage change in the Eczema Area Severity Index (EASI) from baseline to week 6. Secondary endpoints were as follows: EASI improvement ≥50%, 75%, and 90%; IGA score; BSA affected by AD; pruritus severity; and Dermatology Life Quality Index. The safety assessment included adverse events (AEs), laboratory tests, and physical examinations. RESULTS The Lindioil group (32 participants) and vehicle group (16 participants) achieved mean percentage EASI reductions of 49.9% ± 36.5% (95% CI 36.8%-63.1%) and 19.6% ± 52.2% (95% CI -8.2%-47.4%), respectively (P = 0.0235). The Lindioil group also showed greater improvement in every secondary assessment category. No significant AEs occurred. CONCLUSION Indigo naturalis ointment is effective for treating mild to severe AD topically, and appears to be safe. This is the first clinical trial to provide evidence supporting topical indigo-based AD treatment. ClinicalTrials.gov identifier: NCT02669888.

Abstract
Background: Atopic dermatitis is a chronic inflammatory skin disease that remarkably affects the quality-of-life of patients. Chamomile oil is used to treat skin inflammations. We evaluated the efficacy of chamomile oil and nanoemulgel formulations as a natural alternative therapeutic option for atopic dermatitis.Research design and methods: Formulations were developed comprising chamomile oil: olive oil (1:1), Tween 20/80 or Gelucire 44/14 as surfactant-cosurfactant mixtures, propylene glycol (10%w/w), water and hydroxypropyl methylcellulose (3%w/w). In-vitro physicochemical characterization, stability testing and in-vivo assessment of inflammatory biomarkers and histopathological examination of skin lesions were conducted in rats induced with atopic dermatitis.Results: Nanoemulgels G1 and X1 which displayed the smallest particle size of 137.5 ± 2.04 and 207.1 ± 5.44 nm, good homogeneity and high zeta-potential values of -26.4 and -32.7 mV were selected as the optimized emulgel. Nanoemulgels were nonirritating of pH value 5.56, readily spreadable, and were physically stable following 10 heating-cooling cycles. Treatment with nanoemulgels showed a two-fold decrease in duration of skin healing and no spongiosis compared to chamomile oil. Levels of biomarkers were reduced after topical application of both nanoemulgels and chamomile oil.Conclusion: Nanoemulgels are a potential cost effective, safe topical carrier system for chamomile in treating atopic dermatitis.

A randomized controlled, proof-of-principle study. PLoS Negl Trop Dis 2019; 13:e0007822. [PMID: 31756189 PMCID: PMC6897421 DOI: 10.1371/journal.pntd.0007822] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 12/06/2019] [Accepted: 10/01/2019] [Indexed: 01/08/2023] Open
Abstract
Background Tungiasis is a neglected tropical skin disease caused by the female sand flea (Tunga penetrans), which burrows into the skin causing intense pain, itching and debilitation. People in endemic countries do not have access to an effective and safe home treatment. The aim of this study was to determine the efficacy of a traditionally used and readily available mixture of neem and coconut oil for treatment of tungiasis in coastal Kenya. Methodology Ninety-six children aged 6–14 years with at least one embedded viable flea were randomized to be treated with either a mixture of 20% neem (Azadirachta indica) seed oil in coconut oil (NC), or with a 0.05% potassium permanganate (KMnO4) foot bath. Up to two viable fleas were selected for each participant and monitored for 6 days after first treatment using a digital microscope for signs of viability and abnormal development. Acute pathology was assessed on all areas of the feet using a previously established score. Children reported pain levels and itching on a visual scale. Results The NC was not more effective in killing embedded sand fleas within 7 days than the current standard with KMnO4, killing on average 40% of the embedded sand fleas six days after the initial treatment. However, the NC was superior with respect to the secondary outcomes of abnormal development and reduced pathology. There was a higher odds that fleas rapidly aged in response to NC compared to KMnO4 (OR 3.4, 95% CI: 1.22–9.49, p = 0.019). NC also reduced acute pathology (p<0.005), and there was a higher odds of children being pain free (OR 3.5, p = 0.001) when treated with NC. Conclusions Whilst NC did not kill more fleas than KMnO4 within 7 days, secondary outcomes were better and suggest that a higher impact might have been observed at a longer observation period. Further trials are warranted to assess optimal mixtures and dosages. Trial registration The study was approved by the Kenya Medical Research Institute (KEMRI) Scientific and Ethical Review Unit (SERU), Nairobi (Non-SSC Protocol No. 514, 1st April 2016) and approved by and registered with the Pharmacy and Poisons Board’s Expert Committee on Clinical Trials PPB/ECCT/16/05/03/2016(94), the authority mandated, by Cap 244 Laws of Kenya, to regulate clinical trials in the country. The trial was also registered with the Pan African Clinical Trial Registry (PACTR201901905832601). Tungiasis is a disease caused by the female sand flea which burrows into the skin of the feet and causes intense pain and itching. People in endemic tropical areas do not have access to a simple, effective and safe method for treatment at home. The most common treatment used during clinical outreach activities is a foot bath in a disinfectant. Here we report on a clinical trial testing the effectiveness of a mixture of neem and coconut oils to kill the embedded fleas and reduce inflammation, pain and itching. We found the oil mixture reduced the proportion of fleas alive in the foot after 6 days in a similar way as the footbath in disinfectant, which is unavailable to households. However, unlike the footbath, the neem oil treatment caused most of the fleas to rapidly age in the foot and decreased the inflammation, leaving more children pain-free after one week. We conclude the neem and coconut oil mixture could be a promising approach for the treatment of tungiasis but its activity on the fleas might be slower. We need to follow up with longer observation time and test different dosages and application times.

Abstract
BACKGROUND Staphylococcus aureus (S. aureus) can cause secondary infection in eczema, and may promote inflammation in eczema that does not look infected. There is no standard intervention to reduce S. aureus burden in eczema. It is unclear whether antimicrobial treatments help eczema or promote bacterial resistance. This is an update of a 2008 Cochrane Review. OBJECTIVES To assess the effects of interventions to reduce S. aureus for treating eczema. SEARCH METHODS We updated our searches of the following databases to October 2018: Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase and LILACS. We searched five trials registers and three sets of conference proceedings. We checked references of trials and reviews for further relevant studies. We contacted pharmaceutical companies regarding ongoing and unpublished trials. SELECTION CRITERIA Randomised controlled trials of products intended to reduce S. aureus on the skin in people diagnosed with atopic eczema by a medical practitioner. Eligible comparators were a similar treatment regimen without the anti-staphylococcal agent. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Our key outcomes were participant- or assessor-rated global improvement in symptoms/signs, quality of life (QOL), severe adverse events requiring withdrawal, minor adverse events, and emergence of antibiotic-resistant micro-organisms. MAIN RESULTS We included 41 studies (1753 analysed participants) covering 10 treatment categories. Studies were conducted mainly in secondary care in Western Europe; North America; the Far East; and elsewhere. Twelve studies recruited children; four, adults; 19, both; and six, unclear. Fifty-nine per cent of the studies reported the mean age of participants (range: 1.1 to 34.6 years). Eczema severity ranged from mild to severe. Many studies did not report our primary outcomes. Treatment durations ranged from 10 minutes to 3 months; total study durations ranged from 15 weeks to 27 months. We considered 33 studies at high risk of bias in at least one domain. We present results for three key comparisons. All time point measurements were taken from baseline. We classed outcomes as short-term when treatment duration was less than four weeks, and long-term when treatment was given for more than four weeks. Fourteen studies evaluated topical steroid/antibiotic combinations compared to topical steroids alone (infective status: infected (two studies), not infected (four studies), unspecified (eight studies)). Topical steroid/antibiotic combinations may lead to slightly greater global improvement in good or excellent signs/symptoms than topical steroid alone at 6 to 28 days follow-up (risk ratio (RR) 1.10, 95% confidence interval (CI) 1.00 to 1.21; 224 participants; 3 studies, low-quality evidence). There is probably little or no difference between groups for QOL in children, at 14 days follow-up (mean difference (MD) -0.18, 95% CI -0.40 to 0.04; 42 participants; 1 study, moderate-quality evidence). The subsequent results for this comparison were based on very low-quality evidence, meaning we are uncertain of their validity: severe adverse events were rare (follow-up: between 6 to 28 days): both groups reported flare of dermatitis, worsening of the condition, and folliculitis (325 participants; 4 studies). There were fewer minor adverse events (e.g. flare, stinging, itch, folliculitis) in the combination group at 14 days follow-up (218 participants; 2 studies). One study reported antibiotic resistance in children at three months follow-up, with similar results between the groups (65 participants; 1 study). Four studies evaluated oral antibiotics compared to placebo (infective status: infected eczema (two studies), uninfected (one study), one study's participants had colonisation but no clinical infection). Oral antibiotics may make no difference in terms of good or excellent global improvement in infants and children at 14 to 28 days follow-up compared to placebo (RR 0.80; 95% CI 0.18 to 3.50; 75 participants; 2 studies, low-quality evidence). There is probably little or no difference between groups for QOL (in infants and children) at 14 days follow-up (MD 0.11, 95% CI -0.10 to 0.32, 45 participants, 1 study, moderate-quality evidence). The subsequent results for this comparison were based on very low-quality evidence, meaning we are uncertain of their validity: adverse events requiring treatment withdrawal between 14 to 28 days follow-up were very rare, but included eczema worsening (both groups), loose stools (antibiotic group), and Henoch-Schönlein purpura (placebo group) (4 studies, 199 participants). Minor adverse events, including nausea, vomiting, diarrhoea, and stomach and joint pains, at 28 days follow-up were also rare and generally low in both groups (1 study, 68 infants and children). Antibiotic resistance at 14 days was reported as similar in both groups (2 studies, 98 infants and children). Of five studies evaluating bleach baths compared to placebo (water) or bath emollient (infective status: uninfected (two studies), unspecified (three studies)), one reported global improvement and showed that bleach baths may make no difference when compared with placebo at one month follow-up (RR 0.78, 95% CI 0.37 to 1.63; 36 participants; low-quality evidence). One study showed there is probably little or no difference in QOL at 28 days follow-up when comparing bleach baths to placebo (MD 0.90, 95% CI -1.32 to 3.12) (80 infants and children; moderate-quality evidence). We are uncertain if the groups differ in the likelihood of treatment withdrawals due to adverse events at two months follow-up (only one dropout reported due to worsening itch (placebo group)) as the quality of evidence was very low (1 study, 42 participants). One study reported that five participants in each group experienced burning/stinging or dry skin at two months follow-up, so there may be no difference in minor adverse events between groups (RR 1.00, 95% CI 0.35 to 2.87, 36 participants, low-quality evidence). Very low-quality evidence means we are also uncertain if antibiotic resistance at four weeks follow-up is different between groups (1 study, 80 participants ≤ 18 years). AUTHORS' CONCLUSIONS We found insufficient evidence on the effects of anti-staphylococcal treatments for treating people with infected or uninfected eczema. Low-quality evidence, due to risk of bias, imprecise effect estimates and heterogeneity, made pooling of results difficult. Topical steroid/antibiotic combinations may be associated with possible small improvements in good or excellent signs/symptoms compared with topical steroid alone. High-quality trials evaluating efficacy, QOL, and antibiotic resistance are required.

Abstract
Coconut oil is used as a dietary oil worldwide, and its healthy effects are recognized by the fact that coconut oil is easy to digest, helps in weight management, increases healthy cholesterol, and provides instant energy. Although topical application of coconut oil is known to reduce skin infection and inflammation, whether dietary coconut oil has any role in decreasing skin inflammation is unknown. In this study, we showed the impact of dietary coconut oil in allergic skin inflammation by using a mouse model of contact hypersensitivity (CHS). Mice maintained on coconut oil showed amelioration of skin inflammation and increased levels of cis-5, 8, 11-eicosatrienoic acid (mead acid) in serum. Intraperitoneal injection of mead acid inhibited CHS and reduced the number of neutrophils infiltrating to the skin. Detailed mechanistic studies unveiled that mead acid inhibited the directional migration of neutrophils by inhibiting the filamentous actin polymerization and leukotriene B4 production required for secondary recruitment of neutrophils. Our findings provide valuable insights into the preventive roles of coconut oil and mead acid against skin inflammation, thereby offering attractive therapeutic possibilities.

Abstract
PURPOSE OF REVIEW Sales and consumption of coconut oil have been on the raise due to effective marketing strategies. Coconut oil is stated to offer various benefits including weight loss, improvement in immunity, heart health support, and memory enhancement. Also, it is often portrayed as an excellent source of medium chain triglycerides (MCTs). Here, we review the evidence behind the clinical utility of coconut oil consumption. RECENT FINDINGS Several studies consistently showed consumption of coconut oil increases low-density lipoprotein cholesterol (LDL-C) and thereby could increase adverse cardiovascular health. Even though coconut oil has relatively high MCT concentration, the clinical benefits of commercial MCT oils cannot be generalized to coconut oil. Until the long-term effects of coconut oil on cardiovascular health are clearly established, coconut oil should be considered as a saturated fat and its consumption should not exceed the USDA's daily recommendation (less than 10% of total calorie intake).

Abstract
Wounds are a common medical infliction. With the increase in microbial resistance and a shift of interest towards complementary medicines, essential oils have been shown to be beneficial in suppressing microbial growth. However, in practice, essential oils are more often diluted into a base due to the risk of topical adverse effects, such as dermatitis. There is a lack of collated evidence-based information on toxicity and efficacy of carrier oils. The current information on the subject matter is restricted to generic, aroma-therapeutic books and pamphlets, based on anecdotal evidence rather than an experimental approach. Therefore, this review aimed at identifying the recommended carrier oils used in dermatology and thereafter collating the scientific evidence to support the use of carrier oils together with essential oils recommended for dermatological use. Aloe vera gel had multiple studies demonstrating the ability to enhance wound healing; however, several other carrier oils have been largely neglected. It was observed that the extracts for certain plant species had been used to justify the use of the carrier oils of the same plant species. This is an inaccurate cross assumption due to the difference in chemical composition and biological activities. Lastly, despite these carrier oils being recommended as a base for essential oils, very little data was found on the interactive profile of the carrier oil with the essential oil. This review provides a platform for further studies, especially if essential oils are to receive credence in the scientific field.

Abstract
Lauric acid is a green derivate that is abundant in some seeds such as coconut oil where it represents the most relevant fatty acid. Some studies have emphasized its anticancer effect due to apoptosis induction. In addition, the lauric acid is a Phase Change Material having a melting temperature of about 43.2 °C: this property makes it a powerful tool in cancer treatment by hyperthermal stress, generally induced at 43 °C. However, the direct use of lauric acid can have some controversial effects, and it can undergo degradation phenomena in the extracellular environment. For this reason, we have encapsulated lauric acid in a silica shell with a one-step and reproducible synthetic route in order to obtain a monodispersed SiO2@LA NPs with a good encapsulation efficiency. We have used these NPs to expose breast cancer cell lines (MCF-7) at different concentrations in combination with hyperthermal treatment. Uptake, viability, oxidative stress induction, caspases levels, and morphometric parameters were analyzed. These nanovectors showed double action in anticancer treatments thanks to the synergic effect of temperature and lauric acid activity.

Abstract
Despite the availability of effective medications for the management of atopic dermatitis and xerosis, patients may use nonconventional therapies such as topical oils. Patients choose these treatments because of the perceived lower risk of natural products and the fear of potential adverse effects of topical steroids. We review the use of topical olive, coconut, and sunflower seed oil in the treatment of atopic dermatitis and xerosis with a focus on children Currently available evidence suggests that olive oil may exacerbate xerosis and atopic dermatitis. Further studies are needed to make definitive recommendations regarding the use of coconut and sunflower seed oil.

Antimicrobial activity of coconut oil-in-water emulsion on Staphylococcus epidermidis and Escherichia coli EPEC associated to Candida kefyr. Heliyon 2018; 4:e00924. [PMID: 30761360 PMCID: PMC6286180 DOI: 10.1016/j.heliyon.2018.e00924] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2018] [Revised: 06/25/2018] [Accepted: 11/05/2018] [Indexed: 11/21/2022] Open
Abstract
Candida kefyr has been considered both a food-spoiling agent and a type of yeast with fermentation properties. In this study, the authors have evaluated the antimicrobial activity of a coconut oil-in-water emulsion associated to the presence of C. kefyr. Fresh coconut kernels were used to obtain the coconut oil-in-water emulsion, the sterile coconut oil-in-water emulsion by decantation, and the coconut oil by means of a heating process. Commercial virgin coconut oil was also used. Agar diffusion, minimal inhibitory concentration and minimal bactericidal concentration (MIC/MBC) techniques were employed to evaluate antimicrobial activity against E. coli and S. epidermidis. The C. kefyr isolate was identified and confirmed. Coconut milk-derived fatty acids were characterized by acid index and thin layer chromatography. Scanning electronic microscopy was performed to evaluate the morphology of the microorganisms. Lipase activity of C. kefyr isolate was also detected. Coconut oil-in-water emulsion associated to C. kefyr was active against both bacteria. Thin layer chromatography confirmed the presence of triglycerides and free fatty acids. The acid index showed higher acidity potential for the coconut oil-in-water emulsion. The microscopic images showed antibacterial action through the formation of membrane holes' and demonstrated yeast shape. All the above show new potentials for C. kefyr and coconut oil-in-water emulsion in food technology.

Abstract
This guideline was developed as a joint interdisciplinary European project, including physicians from all relevant disciplines as well as patients. It is a consensus-based guideline, taking available evidence from other guidelines, systematic reviews and published studies into account. This first part of the guideline covers methods, patient perspective, general measures and avoidance strategies, basic emollient treatment and bathing, dietary intervention, topical anti-inflammatory therapy, phototherapy and antipruritic therapy, whereas the second part covers antimicrobial therapy, systemic treatment, allergen-specific immunotherapy, complementary medicine, psychosomatic counselling and educational interventions. Management of AE must consider the individual clinical variability of the disease; highly standardized treatment rules are not recommended. Basic therapy is focused on treatment of disturbed barrier function by hydrating and lubricating topical treatment, besides further avoidance of specific and unspecific provocation factors. Topical anti-inflammatory treatment based on glucocorticosteroids and calcineurin inhibitors is used for flare management and for proactive therapy for long-term control. Topical corticosteroids remain the mainstay of therapy, whereas tacrolimus and pimecrolimus are preferred in sensitive skin areas and for long-term use. Topical phosphodiesterase inhibitors may be a treatment alternative when available. Adjuvant therapy includes UV irradiation, preferably with UVB 311 nm or UVA1. Pruritus is targeted with the majority of the recommended therapies, but some patients may need additional antipruritic therapy. Antimicrobial therapy, systemic anti-inflammatory treatment, immunotherapy, complementary medicine and educational intervention will be addressed in part II of the guideline.

Abstract
As skin ages, there is a decline in physiologic function. These changes are induced by both intrinsic (chronologic) and extrinsic (predominately UV-induced) factors. Botanicals offer potential benefits to combat some of the signs of aging. Here, we review select botanicals and the scientific evidence behind their anti-aging claims. Botanicals may offer anti-inflammatory, antioxidant, moisturizing, UV-protective, and other effects. A multitude of botanicals are listed as ingredients in popular cosmetics and cosmeceuticals, but only a select few are discussed here. These were chosen based on the availability of scientific data, personal interest of the authors, and perceived “popularity” of current cosmetic and cosmeceutical products. The botanicals reviewed here include argan oil, coconut oil, crocin, feverfew, green tea, marigold, pomegranate, and soy.

Abstract
Background Emollients are a mainstay of treatment in atopic dermatitis (AD), a disease distinguished by skin bacterial dysbiosis. However, changes in skin microbiota when emollients are used as a potential AD preventative measure in infants remain incompletely characterized. Results We compared skin barrier parameters, AD development, and bacterial 16S ribosomal RNA gene sequences of cheek, dorsal and volar forearm samples from 6-month-old infants with a family history of atopy randomized to receive emollients (n = 11) or no emollients (controls, n = 12). The emollient group had a lower skin pH than the control group. The number of bacterial taxa in the emollient group was higher than in the control group at all sites. The Streptococcus salivarius proportion was higher in the emollient versus control groups at all sites. S. salivarius proportion appeared higher in infants without AD compared to infants with AD. A decrease in S. salivarius abundance was further identified in a separate larger population of older children demonstrating an inverse correlation between AD severity at sampling sites and S. salivarius proportions. Conclusions The decreased skin pH and the increased proportion of S. salivarius after long-term emollient use in infants at risk for developing AD may contribute to the preventative effects of emollients in high-risk infants.
