    A lamellar liquid crystalline region was identified in a typical skin lotion formulation system composed of a mixture of isostearic acid and triethanolamine (TEA) at 65:35 (w/w), decane, and water (the temperature was controlled at 30 degrees C). The interlayer spacings were determined by a small-angle X-ray diffraction technique. Incorporation of a natural dye, curcumin, resulted in lower interlayer spacings and higher penetration of water into the layered structure. However, the higher penetration of water was not apparent at all compositions of isostearic acid:TEA, decane, and water.

    OBJECTIVE: Comparative trials of benzoyl peroxide (BPO) have yielded contradictory results on its effectiveness for acne vulgaris. The aim of the study was to synthesise the evidence for the effectiveness of BPO-containing topical products for facial acne vulgaris.
    DESIGN: Systematic review.
    METHODS: The Cochrane Central Register of Controlled trials, Cochrane Library, MEDLINE and other relevant databases were searched without publication date or language restriction.
    RESULTS: We identified 22 trials involving 2212 participants; 12 trials compared BPO as single agent while the other 10 trials compared BPO in combination products. All trials reported lesion count as the outcome measure but only five trials provided numerical data. However, pooling of data from these trials was inappropriate due to variations between trials in terms of acne severity, comparator used and trial duration. Overall the study quality was fair but most studies had some bias particularly in method of random generation and allocation concealment. Although the results provide some evidence that BPO reduces acne-lesion count, the available evidence is not robust enough for firm conclusions.
    CONCLUSIONS: There is no high quality evidence that topical BPO improves facial acne vulgaris, and further research is needed.

    BACKGROUND: Topical corticosteroids (TCS) are commonly available in community pharmacies and are used in skin conditions like atopic dermatitis and psoriasis among others. Problems such as overuse, use of potent steroids and steroid phobia have been identified in the use of TCS in the literature. The aim of the study was to obtain community pharmacists (CPs) views regarding factors influencing their counselling of patients about TCS; challenges associated, important problems, the counselling process, shared care with other healthcare professionals, and explore further the findings from the questionnaire-based study.

    METHODS: Seven licensed practicing community pharmacists (from the Klang Valley, Malaysia) were interviewed between 23rd September to 14th November 2021. These were CPs participating in the questionnaire study who agreed to be interviewed. NVIVO 11 software was used for data analysis. Codes and themes were generated and agreed on by the researchers.

    RESULTS: The major themes identified related to the process mentioned of providing information to patients, the issues addressed by CPs during the counselling (including steroid phobia, overuse of TCS, patients asking for a specific preparation by name), less counselling support material, language barriers, lesser knowledge about certain conditions, information sources used by CPs (material provided by Ministry of Health and Malaysian Pharmacists Association, MIMS) and suggestions to strengthen the quality of counselling (specialization in skin diseases, webinars, shared care models). For patients requesting a particular preparation by name, the pharmacist will decide whether the preparation requested is suitable or suggest an alternative. Steroid phobia was seen more commonly among parents of young children and young patients. MIMS was available as a smartphone application making it easier to use. Advanced training for CPs in the management of skin conditions like that provided for diabetes mellitus can be considered.

    CONCLUSIONS: Counselling was conducted while dispensing TCS in the open area of the pharmacy. Challenges to counselling were lack of time, limited counselling materials, and language barriers. Steroid phobia requires attention. Initiatives to strengthen counselling were mentioned by respondents and appear feasible. Further research covering the entire country is required.

    Psoralen or furocoumarin is a linear three ring heterocyclic compound. Psoralens are planar, tricyclic compounds, consisting of a furan ring fused to a coumarin moiety. Psoralen has been known for a wide spectrum of biological activities, spanning from cytotoxic, photosensitizing, insecticidal, antibacterial to antifungal effect. Thus, several structural changes were introduced to explore the role of specific positions with respect to the biological activity. Convenient approaches utilized for the synthesis of psoralen skeleton can be categorized into two parts: (i) the preparation of the tricyclic ring system from resorcinol, (ii) the exocyclic modification of the intact ring system. Furthermore, although psoralens have been used in diverse ways, we mainly focus in this work on their clinical utility for the treatment of psioraisis, vitiligo and skin-related disorder.

    Topical emulsions stabilized with non-ionic emulsifiers have been an attractive alternative as vehicles for drug delivery, particularly for the patients suffering from dermatological problems. Haruan (a natural wound healer) creams were formulated with different types of emulsifiers (Tween 80 and Span 80) using different grades of Malaysian Palm-oleins (DFPL 56, 60, 62 and 65). The stability (at room temperature and accelerated stability testing) of the various creams was evaluated at different temperatures (5, 25 and 45 degrees C) for a period of 6 months by measuring changes in droplet size, viscosity and percentage oil separation. The emulsifier type and concentration showed pronounced effect on the physicochemical properties of the cream, whereas storage time did not. This study suggested that the choice of emulsifiers and concentration of haruan extract are the most important factors in the stability of the haruan creams.

    Hydrocortisone cream intended for atopic eczema often produces unwanted side effects after long-term use. These side effects are essentially due to repeated percutaneous administration of the medication for skin dermatitis, as atopic eczema is a relapsing disorder. Hence, there is a need to develop a new hydrocortisone formulation that will deliver the drug more effectively and require a reduced dosing frequency; therefore, the side effects could be minimized. In this study, a hydroxypropyl methylcellulose (HPMC) lyogel system based on 80% organic and 20% aqueous solvents containing 1% hydrocortisone was formulated. The hydrocortisone lyogel physicochemical characteristics, rheological properties, stability profile, and in vitro Franz cell drug release properties, as well as the in vivo therapeutic efficacies and dermal irritancy in Balb/c mice were investigated. The HPMC lyogel appeared clear and soft and was easy to rub on the skin. The lyogel also showed a higher drug release profile compared with commercial hydrocortisone cream. Similar to the cream, HPMC lyogels exhibited pseudoplastic behavior. From the mouse model, the hydrocortisone lyogel showed higher inflammatory suppressive effects than the cream. However, it did not reduce the transepidermal water loss as effectively as the control did. The dermal irritancy testing revealed that the hydrocortisone lyogel caused minimal irritation. In conclusion, HPMC lyogel is a promising vehicle to deliver hydrocortisone topically, as it showed a higher drug release in vitro as well as enhanced therapeutic efficacy in resolving eczematous inflammatory reaction compared with commercial cream.

    BACKGROUND: Higher skin pH in atopic dermatitis contributes to impaired epidermal barrier. A moisturizer compatible with physiological pH could improve atopic dermatitis.

    OBJECTIVE: To determine the effect of a physiologically compatible pH moisturizer in atopic dermatitis.

    METHODS: A randomized half body, double blind, controlled trial involving patients with stable atopic dermatitis was performed. pH-modified moisturizer and standard moisturizer were applied to half body for 6 weeks.

    RESULTS: A total of 6 (16.7%) males and 30 (83.3%) females participated. Skin pH reductions from week 0, week 2 and 6 were significant at the forearms (5.315 [0.98] to 4.85 [0.54] to 5.04 [0.78], p=0.02) and abdomen (5.25 [1.01], 4.82 [0.64], 5.01 [0.59], p=0.00) but not at the shins (5.01 [0.80], 4.76 [0.49], 4.85 [0.79], p=0.09) with pH-modified moisturizer. Transepidermal water loss (TEWL) at the forearms decreased (4.60 [2.55] to 3.70 [3.10] to 3.00 [3.55], p=0.00), abdomen (3.90 [2.90] to 2.40 [3.45] to 2.70 [2.25], p=0.046). SCORAD improved from 14.1±12.75 to 10.5±13.25 to 7±12.25, p=0.00. In standard moisturizer group, pH reductions were significant at the forearms (5.29 [0.94] to 4.84 [0.55] to 5.02 [0.70], p=0.00) and abdomen (5.25 [1.09], 4.91 [0.63], 5.12 [0.66], p=0.00). TEWL at the forearm were (4.80 [2.95], 4.10 [2.15], 4.60 [3.40], p=0.67), shins (3.80 [1.40], 3.50 [2.35], 4.00 [2.50], p=0.91) and abdomen (3.70 [2.45], 4.10 [3.60], 3.40 [2.95], p=0.80). SCORAD improved from 14.2±9.1 to 10.9±10.65 to 10.5±11, p=0.00. Reduction in pH was observed with both moisturizers while TEWL significantly improved with pH-modified moisturizer. pH-modified moisturizer resulted in greater pH, TEWL and SCORAD improvements however the differences were not significant from standard moisturizer.

    STUDY LIMITATION: Skin hydration was not evaluated.

    CONCLUSION: Moisturization is beneficial for atopic dermatitis; use of physiologically compatible pH moisturizer is promising.

    Insulin, insulin-like growth factor-1 (IGF-1) and essential amino acids activate the mechanistic target of rapamycin complex 1 (mTORC1), the main nutrient-sensitive kinase. Metformin, through inhibition of mTORC1 may improve acne. A 12-week, randomized, open-labeled study evaluated the efficacy and safety of metformin as an adjunct for moderate to severe facial acne. In total, 84 patients received either oral tetracycline 250 mg bd and topical benzoyl peroxide 2.5% with or without metformin 850 mg daily. Evaluations constituted lesion counts, the Cardiff Acne Disability Index (CADI), metabolic parameters and treatment success rate (Investigators Global Assessment score of 0 or 1 or improvement of two grades). Treatment success rates were higher in the metformin group (66.7% vs. 43.2%; p = .04). The mean percentage reduction from baseline in total lesion counts at Week 12 was greater in the metformin group (71.4% vs. 65.3%; p = .278). The CADI scores showed a greater mean reduction in the metformin group (4.82 vs. 4.22; p = .451). Metformin was equally efficacious in improving acne in lean and overweight subjects. Gastrointestinal symptoms were noted in 31.7% of subjects on metformin. This study presents favorable data for metformin as an adjunct for acne treatment. Further randomized placebo-controlled studies are required.

    BACKGROUND: Blechnum orientale Linn. (Blechnaceae) is used ethnomedicinally to treat wounds, boils, blisters or abscesses and sores, stomach pain and urinary bladder complaints. The aim of the study was to validate the ethnotherapeutic claim and to evaluate the effects of B. orientale water extract on wound healing activity.

    METHODS: Water extract of B. orientale was used. Excision wound healing activity was examined on Sprague-Dawley rats, dressed with 1% and 2% of the water extract. Control groups were dressed with the base cream (vehicle group, negative control) and 10% povidone-iodine (positive control) respectively. Healing was assessed based on contraction of wound size, mean epithelisation time, hydroxyproline content and histopathological examinations. Statistical analyses were performed using one way ANOVA followed by Tukey HSD test.

    RESULTS: Wound healing study revealed significant reduction in wound size and mean epithelisation time, and higher collagen synthesis in the 2% extract-treated group compared to the vehicle group. These findings were supported by histolopathological examinations of healed wound sections which showed greater tissue regeneration, more fibroblasts and angiogenesis in the 2% extract-treated group.

    CONCLUSIONS: The ethnotherapeutic use of this fern is validated. The water extract of B. orientale is a potential candidate for the treatment of dermal wounds. Synergistic effects of both strong antioxidant and antibacterial activities in the extract are deduced to have accelerated the wound repair at the proliferative phase of the healing process.

    Psoriasis is a chronic autoimmune skin disorder affecting 2-3% of the world population. It has characteristic features such as increased keratinocyte proliferation and production of inflammatory mediators. The treatment involves various strategies including topical, systemic, phototherapy and biologics. Topical therapies are preferred for mild to moderate psoriasis conditions over the systemic therapies which are ideal in severe disease conditions. The systemic therapies include immunosuppressants, biological agents and recently approved phosphodiesterase-4 (PDE4) inhibitors. There are various limitations associated with the existing therapies where the new findings in the pathogenesis of psoriasis are paving a path for newer therapeutics to target at the molecular level. Various small molecules, PDE-4 inhibitors, biologics, and immunomodulator proved efficacious including the new molecules targeting Janus kinases (JAK) inhibitors that are under investigation. Furthermore, the role of genetic and miRNAs in psoriasis is still not completely explored and may further help in improving the treatment efficacy. This review provides an insight into various emerging therapies along with currently approved treatments for psoriasis.

    BACKGROUND:Psoriasis is an immune-mediated, chronic, inflammatory skin disease which affects approximately 2% of the world's population. It has a major impact on the patient's quality of life (QoL), influencing career, social activities, family relationships, and all other aspects of life. Many studies have described the various ways in which psoriasis can affect a patient's life. Very little is known, however, about the impact of psoriasis on the QoL of patients treated in Malaysia and the cost of illness in this region.
    OBJECTIVES: This study aims to describe the extent to which psoriasis affects the QoL of patients treated in government-run dermatology clinics in Malaysia and to estimate the cost of illness.
    METHODS: A total of 250 psoriasis patients treated at eight dermatology clinics in government-run hospitals in Malaysia were studied. The severity of psoriasis was assessed by dermatologists. Quality of life was evaluated using the Dermatology Life Quality Index (DLQI) and Version 2 of the 12-Item Short-Form Health Survey (SF-12v2). Scores on the SF-12v2 of healthy subjects and of patients with other medical conditions, such as depression, diabetes mellitus, hypertension, and ischemic heart disease, were also assessed for comparison. The costs of dermatology outpatient consultant fees, medications, investigations, procedures, transportation, over-the-counter medications, and hospitalization were retrospectively estimated using questionnaires.
    RESULTS: The cohort studied had a median Psoriasis Area Severity Index (PASI) score of 9.9 and a median DLQI score of 10.0. The average SF-12v2 scores were 43.68 (standard deviation [SD] 9.23) and 42.25 (SD 10.7) on the Physical Health Summary and Mental Health Summary, respectively. The impact of disease on QoL was found to be greater in those with more extensive psoriatic lesion involvement, in younger patients, and in those with psoriatic arthropathy. Psoriasis was found to affect QoL in both genders equally. Body mass index had no effect on the severity of psoriasis or QoL. Patients with psoriasis had a significantly lower SF-12v2 score than healthy subjects. Comparisons with data for patients with other chronic medical conditions demonstrated that psoriasis has a negative effect on health-related QoL similar to the impact of other chronic conditions. The estimated cost of illness for psoriasis in the current cohort was ringgit Malaysia (RM) 1307.47 per person per year excluding costs of hospitalization. Patients were noted to spend a large amount of money on over-the-counter products obtained without doctors' prescriptions.
    CONCLUSIONS: The QoL of patients with psoriasis was significantly impaired compared with that of healthy subjects and was comparable with that of patients with other chronic medical illnesses. The estimated cost of illness of psoriasis in the current study was lower than in other countries, mainly because healthcare costs in public hospitals are heavily subsidized by government and because usage of newer but more expensive treatment options is low in Malaysia.

    BACKGROUND: Methotrexate (MTX) is a common and efficacious systemic agent used for the treatment of moderate to severe psoriasis. Nevertheless, its use is associated with the risk of hepatotoxicity. This study was performed to study the association of MTX dose with regards to hepatotoxicity as evidenced by deranged transaminases.
    METHODS: This was a retrospective review of patients with psoriasis on MTX from 2000 to 2009 at the outpatient dermatology clinic, University Malaya Medical Centre (UMMC). We analyzed patients' demography, serial laboratory investigations, liver ultrasounds, and liver biopsies of patients on MTX.
    RESULTS: Sixty-six of 710 (9.30%) patients with psoriasis were prescribed MTX throughout the 10-year period. Among them 57.6% developed deranged transaminases, with six requiring MTX withdrawal due to hepatotoxicity. The mean cumulative dose of MTX at the detection of liver enzyme derangement was 552.3 ± 596.1 mg.
    CONCLUSION: A high proportion of patients on MTX had deranged transaminases. However, the number of serious events was low. We concluded from this study that the use of MTX is relatively safe in patients with moderate to severe psoriasis.
