Abstract
Background and Aim: Although several commercial moisturizers are available in the market, continued role of pharmaceutical compounding have been still felt in dry skin management. This study aimed to evaluate the effect of a two urea- based compounded moisturizers on barrier function, compared to similar commercial product. 15 volunteers (14 females and one male) age 36.15 ±9.55 years old (range 21-56 years old) with non-pathologic dry skin, recruited to the study applied 5% urea containing hydrophilic petrolatum and 10% urea containing hydrophilic petrolatum during two following phases.
Methods: Upper parts of right and left forearms randomly were assigned for twice a day application of commercial or compounded products. Biophysical assessments including trans epidermal water loss (TEWL), skin hydration, friction co efficient, pH and surface lipids, performed before intervention, 1, 4 after single application and at 24 hours and one week twice daily application.
Results: In both phases, commercial and compounded moisturizers showed appropriate and comparable effect on skin barrier function compared to the baseline. However commercial products, led to better improvement in TEWL, 4 hours after single application in both phases (P=0.04). The rate of increase in skin hydration was also significantly higher for commercial emollient, compared to compounding product (57.48±11.23 vs. 50.59±11.42, P=0.01).
Conclusion: Commercial formulation led to higher acceptability and better improvement on skin barrier function after single application, probably due to influence of excipients. Present study did not find sufficient added value for pharmacy product relative to commercial one and suggest to be replaced in similar condition.

Abstract
Alterations in barrier function are associated with a number of skin diseases, including xerosis, atopic dermatitis, and psoriasis. Urea, a component of the natural moisturizing factor of the skin, plays an important role in the preservation of skin hydration and integrity. Several studies have investigated the effects of urea in the clinical setting. Here, we summarize the available clinical evidence regarding the effects of urea in the maintenance of healthy skin and management of skin disorders. At lower doses (≤10%),
urea-containing topical formulations act as a skin moisturizer, while at higher concentrations (>10% urea), urea-based preparations exert a keratolytic action. Urea is also useful in combination therapies with anti-inflammatory and anti-fungal drugs, due to its activity as a penetration enhancer.

Abstract
Background and Aim: Hair loss is one of the most common problems among the skin and hair related diseases. Hair loss can lead to anxiety, depression, low self-esteem and dissatisfaction with appearance.
Methods: Patients with androgenetic alopecia who met the eligibility criteria entered the study. Participants were asked to randomly apply a solution of valproic acid 8.3% or a solution of minoxidil 5% on the affected areas according to the treatment protocol (twice a day). Before and 2 months after treatment, the participants were evaluated. The studied indices included the number of hair follicles in the specified area, the number of velus hairs, the number of terminal hairs, the average hair thickness, and the percentage of hairs in the anagen and telogen phases, as well as the skin reactions in the area. Hairs were examined at the beginning of the study and at 2 months after treatment using Foto Finder-trichoscale device.
Results: Two months after treatment compared to baseline in the valproic group, anagen hair count index (P=0.02), general hair count index (P=0.03), and terminl hair count index (P=0.012) showed significant changes. While telogen hair count (P=0.059) and vellus hair count (P=0.097) did not show significant changes. These changes were more significated in minoxidil group.
Conclusion: 8.3% valproic acid solution showed positive effects in increasing the number of hairs and decreasing the percentage of telogen hairs. Due to the delayed mechanism of valproic acid, the duration of treatment with this compound should be considered longer than minoxidil as a positive control.

Abstract
Background and Aim: Oral hydrolyzed collagen is one of the newest and most popular systemic supplementations for skin rejuvenation. However, there are limited information in case of Middle Eastern consumers. The purpose of this study was to evaluate the tolerability and efficacy of an oral collagen supplement for improvement of skin elasticity, hydration and roughness.
Methods: It was a 12-week, before-after clinical study, conducted on 20 participants (18 women and two men) aged 44.15±5.36 years with skin type III-IV. Skin elasticity parameters (R0, R2, R5 and R7), skin hydration and friction, as well as the thickness and echo density of the dermis, were measured after six and 12 weeks daily intake of the study product, as well as four weeks after stopping its use (week 16). Participants’ satisfaction was assessed on the basis of their answers to the standard questionnaire, and tolerability of the product was assessed by monitoring the adverse effects.
Results: A significant improvement was detected in R2, R5 and skin friction at week 12 (P<0.041, P<0.012 and P<0.01, respectively). At week 16, the values remained at an increased level, which indicates the stability of the results. The increase of dermis density in week 16 was also significant (P=0.03). Moderate overall satisfaction was reported with the treatment, and a few gastrointestinal complications were reported.
Conclusion: The study demonstrated that oral collagen peptides could significantly improve the skin elasticity, roughness, and dermis echo density, and they also proved to be safe and well-tolerated.

Abstract
Background and Aim: Cutaneous leishmaniasis is one of the most important health problems in Iran. There is still no effective vaccine available against human leishmaniasis and current treatment is based on chemotherapy. Conventional drugs are toxic and expensive, and drug resistance has caused the search for new treatments. Tofacitinib is a Janus kinase inhibitor that disturbs the signaling pathway of several cytokines in the immune system. The aim of this study was to evalute the effect of topical tofacitinib 2% ointment in healing cutaneous leishmaniasis in Balb/C mice.
Methods: This experimental study was performed using tofacitinib and glucantim drugs in 40 female Balb/C mice. The metacyclic form of promastigote of Leishmania major standard strain (MRHO/IR/75/ER) was injected into the footpad of the mice, the mice were divided into 4 treatment groups: tofacitinib, glucantim, tofacitinib-glucantim and control without treatment. The treatment period was 28 days. The footpad thickness of all groups was measured at the end of each week.
Results: After the end of the treatment in the groups treated with tofacitinib, a significant decrease in the size of lesion and the footpad thickness was observed compared to the control group without treatment (P<0.01).
Conclusion: It seems that tofacitinib ointment accelerates lesion healing in Balb/C mice and has worked similarly to standard glucantim treatment. Ointment can be a better option for leishmaniasis treatment and due to its ease of use and no need for painful injections it can be considered as an option for the treatment of patients with cutaneous leishmaniasis.
