Abstract
BACKGROUND Treatment of vitiligo is still a big challenge for dermatologists. The efficacy of statins in the treatment of vitiligo is controversial. AIM AND OBJECTIVE We studied possible therapeutic effect of topical 1% niosomal atorvastatin ointment combined with topical 0.1% tacrolimus in treatment of non-segmental vitiligo. METHODS This is a triple blind, pilot, randomized placebo-controlled trial (RCT) that was performed in dermatology clinic. All the patients used topical 0.1% tacrolimus cream twice daily (BD). Moreover, the intervention group participants used topical 1% niosomal atorvastatin ointment, and control group participants were prescribed placebo ointment, BD. Patients were evaluated using vitiligo area surface index (VASI) score and patients' satisfaction at baseline and after 3 months treatment. RESULTS The mean patient satisfaction in the intervention and control groups were 5 ± 1.4 and 3.5 ± 1.9; the difference between groups was not statistically significant (p = 0.9). We found statistically significant difference in VASI score before and after treatment in both intervention and control groups (p = 0.01 and p = 0.03, respectively). However, comparison of the VASI score between groups was not statistically significant (p = 0.62). We also found no significant correlation between VASI score and other variables. CONCLUSION The result of this study indicates that adding of niosomal atorvastatin 1% ointment to topical calcineurin inhibitor has no additional effect on non-segmental type of vitiligo. Further large studies with different combinations are recommended before any conclusive result can be concluded on efficacy of statins in vitiligo.

Abstract
BACKGROUND Histopathologic differentiation of Lichen planopilaris (LPP) and discoid lupus erythematosus (DLE) as the two common causes of primary cicatricial alopecias remains challenging. METHOD We performed a histopathologic study on a case series of LPP and DLE specimens to investigate the number, distribution, and morphology of mast cells as indices for differentiation of these two entities. H & E investigation and Giemsa staining for the detection of mast cells was performed. RESULT A total of 74 cases comprising 50 cases of LPP and 24 cases of DLE, were assessed. The mean mast cell count and percentage were significantly higher in LPP group (P <0.001). Mean degranulated mast cell count and the mean intact mast cell count were also significantly higher in LPP patients (P <0.001). Most of the specimens, 58 (78.4%), showed both perifollicular and perivascular distribution of mast cells without significant diffrence between two groups. The morphology of mast cells was predominantly round-oval in 85.5%, predominantly fusiform in 13.5% with more frequent fusiform morphology in DLE group. CONCLUSION The mast cell count detected by Giemsa staining could assist pathologists in distinguishing between LPP and DLE. This article is protected by copyright. All rights reserved.

Abstract
BACKGROUND Mesotherapy is a popular novel therapeutic modality that is defined as intradermal or subcutaneous microinjection of pharmaceutical compounds. Although this novel treatment method is used commonly in aesthetic dermatology, there is little information about details of injections, efficacy, and side effects of mesotherapy in melasma. AIM In this review, we evaluated efficacy and safety of various types of mesotherapy in the treatment of melasma. METHOD We searched Google Scholar, Medline, and PubMed for related articles with keywords "melasma" OR "chloasma" AND "mesotherapy" OR "injection." Inclusion criteria were articles that evaluated intradermal injection of lightening drugs and published dates between January 2000 and September 2021. Exclusion criteria were articles in languages other than English or non-human studies. RESULTS Thirty-three articles evaluated efficacy of mesotherapy in melasma, including 28 articles about tranexamic acid, 4 articles about vitamin C, 2 articles about glutathione, and 2 articles about triamcinolone. CONCLUSION Mesotherapy is a good alternative or adjunctive choice in patients who are refractory to first-line therapy, patients with low compliance with everyday use of topical therapy, patients with contraindication to oral tranexamic acid therapy, or who wish short downtime and fast recovery period. Further studies with large sample sizes are required to determine ideal concentrations of mesotherapy substances and intervals between sessions and to evaluate the efficacy of different substances for mesotherapy as monotherapy compared to combination therapy and other treatment modalities for melasma.

Abstract
Traditional treatment modalities for wart require long-term treatment course and usually have high recurrence rates and unwanted side effects. In this review article, we evaluated different types of laser therapy in the treatment of warts. Published articles since 2000 up to July 2020 about laser therapy in genital and non-genital warts were searched and assessed. Fifty articles were selected for the final review, including 22 pulsed dye laser (PDL), 10 neodymium-yttrium-aluminum-garnet (Nd: YAG), 3 erbium-doped yttrium-aluminum-garnet (Er: YAG), 14 carbon dioxide (CO2 ) laser and one systematic review. Complete response rates were different in terms of laser type used (0%-100%, 9.1%-100%, 83.3%-100%, and 59.15%-100% for PDL, Nd: YAG, Er: YAG, and CO2 laser, respectively). There was no significant difference between conventional treatment modalities and laser therapy regarding efficacy and recurrence rate. Combination of lasers with keratolytic agents, immunomodulators and photodynamic therapy can be helpful especially in immunosuppressed patients, refractory, and recurrent lesions. PDL has the lowest occurrence of adverse effects relative to other types of lasers.

Abstract
Dysgeusia is the first recognized oral symptom of novel coronavirus disease (COVID‐19). In this review article, we described oral lesions of COVID‐19 patients. We searched PubMed library and Google Scholar for published literature since December 2019 until September 2020. Finally, we selected 35 articles including case reports, case series and letters to editor. Oral manifestations included ulcer, erosion, bulla, vesicle, pustule, fissured or depapillated tongue, macule, papule, plaque, pigmentation, halitosis, whitish areas, hemorrhagic crust, necrosis, petechiae, swelling, erythema, and spontaneous bleeding. The most common sites of involvement in descending order were tongue (38%), labial mucosa (26%), and palate (22%). Suggested diagnoses of the lesions were aphthous stomatitis, herpetiform lesions, candidiasis, vasculitis, Kawasaki‐like, EM‐like, mucositis, drug eruption, necrotizing periodontal disease, angina bullosa‐like, angular cheilitis, atypical Sweet syndrome, and Melkerson‐Rosenthal syndrome. Oral lesions were symptomatic in 68% of the cases. Oral lesions were nearly equal in both genders (49% female and 51% male). Patients with older age and higher severity of COVID‐19 disease had more widespread and sever oral lesions. Lack of oral hygiene, opportunistic infections, stress, immunosuppression, vasculitis, and hyper‐inflammatory response secondary to COVID‐19 are the most important predisposing factors for onset of oral lesions in COVID‐19 patients.

Abstract
Background Lichen planus (LP) is a chronic inflammatory disease of the skin. Currently, noninvasive techniques are used to evaluate biophysical properties of the skin in vivo. Objective In this study, we aimed to evaluate skin biophysical properties in patients with LP and make a comparison between involved and uninvolved skin to provide a better understanding of the pathogenesis of LP. Methods The stratum corneum hydration, transepidermal water loss, pH, erythema, melanin, sebum, friction, temperature, elasticity parameters (R0, R2, R5), and thickness and echo-density of the epidermis, dermis, and subepidermal low echogenic band were measured on lesions of classic LP in 21 patients and compared with the average of perilesional and symmetrical uninvolved skin (as control) with a paired t test. Results Stratum corneum hydration (p = .002), sebum (p = .04), R0 (p = .005), and echo-density of the dermis (p = .005) were significantly lower, but pH (p = .007), melanin content (p < .001), erythema (p < .001), temperature (p = .01), thickness of dermis (p = .02), and subepidermal low echogenic band (p < .001) were significantly higher in LP lesions. Conclusion An evaluation of its biophysical, biomechanical, and ultrasonographic characteristics showed that the skin is an objective, noninvasive, and quantitative measuring tool that can be used to provide valuable information about skin changes in classic LP.

Abstract
BACKGROUND The authors aimed to evaluate the efficacy of a bioimplant dressing in comparison with a wet dressing in patients with diabetic foot ulcers (DFUs). MATERIALS AND METHODS Fifty-seven patients with diabetes who had an ulcer of Wagner Grades 2-4 were included in this controlled clinical trial. The study was conducted in the outpatient diabetic foot clinic of Dr. Shariati Hospital, affiliated with the Endocrinology and Metabolism Research Institute, Tehran University of Medical Sciences, Tehran, Iran, from November 2010 to March 2012. Fifty-seven cases of DFUs were equally and randomly divided into control and test groups. The bioimplant group received an amniotic membrane dressing while the control group was treated with a wet dressing. Both groups were evaluated once a week for 6 weeks for the degree of epithelialization and granulation tissue of the wound. RESULTS The complete healing rate (ie, wound closure) in the whole study population was 28.1% (control group, 16.7%; bioimplant group, 40.7%, P = 0.04). In 21 patients (77.77%) of the bioimplant group, granulation tissue was extended within the third visit. Amputation and hospitalization rates were higher in the control group compared to the bioimplant group; however, the difference was not statistically significant (relative risk [RR]: 1.11, 95% CI 0.91-1.34, P = 0.258; RR: 1.27, 95% CI 0.97-1.66, P = 0.076, respectively). CONCLUSION The bioimplant dressing was significantly superior to the wet dressing in prompting the complete healing of DFUs. Ease of use, absence of adverse effects, and a facilitated wound healing process are among properties of amniotic membrane that make it an appropriate dressing in the management of DFUs. Additional research will shed more light on the promising advantages of this material in healing DFUs.

Abstract
BACKGROUND The more recent use of ultrasound scanning allows a direct measurement on unmodified skin, and is considered to be a reliable method for in vivo measurement of epidermal and dermal thickness. The objective of this study was to assess the influence of gender and age on the thickness and echo-density of skin measured by high frequency ultrasonography (HFUS). MATERIALS AND METHODS This study was carried out on 30 healthy volunteers (17 female, 13 male) with age range of 24-61 years old. The thickness and echo-density of dermis as well as epidermal entrance echo thickness in five anatomic sites (cheek, neck, palm, dorsal foot, and sole) were measured using two different types of B mode HFUS, 22 and 50 MHz frequencies. RESULTS The epidermal entrance echo thickness and thickness of dermis in males were higher than females, which was statistically significant on neck and dorsum of foot. The echo-density of dermis was higher in females on all sites, but was only statistically significant on neck. The epidermal entrance echo thickness and thickness of dermis in young age group was statistically higher than old group on sole and dorsal of the foot respectively. Overall, the skin thickness decreased with age. CONCLUSION High frequency ultrasonography method provides a simple non-invasive method for evaluating the skin thickness and echo-density. Gender and age have significant effect on these parameters. Differences in study method, population, and body site likely account for different results previously reported.

Abstract
Nocebo effect, originally denoting the negative counterpart of the placebo phenomenon, is now better defined as the occurrence of adverse effects to a therapeutic intervention because the patient expects them to develop. More commonly encountered in patients with a past negative experience, this effect stems from highly active processes in the central nervous system, mediated by specific neurotransmitters and modulated by psychological mechanisms such as expectation and conditioning. The magnitude of nocebo effect in clinical medicine is being increasingly appreciated and its relevance encompasses clinical trials as well as clinical practice. Although there is hardly any reference to the term nocebo in dermatology articles, the phenomenon is encountered routinely by dermatologists. Dermatology patients are more susceptible to nocebo responses owing to the psychological concern from visibility of skin lesions and the chronicity, unpredictable course, lack of 'permanent cure' and frequent relapses of skin disorders. While finasteride remains the prototypical drug that displays a prominent nocebo effect in dermatologic therapeutics, other drugs such as isotretinoin are also likely inducers. This peculiar phenomenon has recently been appreciated in the modulation of itch perception and in controlled drug provocation tests in patients with a history of adverse drug reactions. Considering the conflict between patients' right to information about treatment related adverse effects and the likelihood of nocebo effect stemming from information disclosure, the prospect of ethically minimizing nocebo effect remains daunting. In this article, we review the concept of nocebo effect, its postulated mechanism, relevance in clinical dermatology and techniques to prevent it from becoming a barrier to effective patient management.

Abstract
Background: The exposure of skin to ultraviolet radiation and temperature differs significantly during the day. It is reasonable that biophysical parameters of human skin have periodic daily fluctuation. The objective of this study was to study the fluctuations of various biophysical characteristics of Middle Eastern skin in standardized experimental conditions. Materials and Methods: Seven biophysical parameters of skin including stratum corneum hydration, transepidermal water loss, pH, sebum, elasticity, skin color, and erythema index were measured at three time points (8 a.m., 12 p.m. and 4 p.m.) on the forearm of 12 healthy participants (mean age of 28.4 years) without any ongoing skin disease using the CK MPA 580 device in standard temperature and humidity conditions. Results: A significant difference was observed between means of skin color index at 8 a.m. (175.42 ± 13.92) and 4 p.m. (164.44 ± 13.72, P = 0.025), between the pH at 8 a.m. (5.72 ± 0.48) and 4 p.m. (5.33 ± 0.55, P = 0.001) and pH at 12 p.m. (5.60 ± 0.48) and 4 p.m. (5.33 ± 0.55, P = 0.001). Other comparisons between the means of these parameters at different time points resulted in nonsignificant P values. Conclusion: There are daytime changes in skin color index and pH. Skin color index might be higher and cutaneous pH more basic in the early morning compared to later of the day.

Abstract
BACKGROUND Botulinum neurotoxin type A (BTX-A) injection is the treatment of choice for idiopathic axillary hyperhidrosis (IAH) refractory to conventional treatments. OBJECTIVE This study compared the efficacy of BTX-A injection and iontophoresis for treatment of IAH in a randomized controlled trial. METHODS In eleven patients with the diagnosis of IAH, one axilla was randomly treated with injections of 1.5 mL (250 MU) of BTX-A, and the other side was treated with BTX-A administered by iontophoresis. The amount of sweating, skin hydration, transepidermal water loss, pain, and patient satisfaction on both axilla were compared with baseline levels, and also between both sides 1 week, 1 month, and 6 months after treatment. RESULTS The injection side had significantly less sweat production than the iontophoresis side 1 week, 1 month, and 6 months after treatment (84%, 76%, and 50% vs. 73%, 22%, and 32%, respectively). The response to iontophoresis was more stable than that to injection. Participants' pain perception during the procedure score was significantly less on the iontophoresis side compared with the injection side (15.0 vs. 20.0, p < 0.05). CONCLUSION This study has shown that injection is a more effective method for the administration of BTX-A, though iontophoresis can also be considered a non-invasive and painless method in some patients.

Abstract
In the present study, involvement of D1 and D2 dopamine receptors in the antinociception and tolerance induced by water swim stress in the formalin test has been investigated. Water swim stress at 20 degrees C temperature induced antinociception in both phases of the formalin test. Intraperitoneal administration of the D2 dopamine receptor antagonist, sulpiride (25 and 50 mg/kg) reduced swim stress-induced antinociception in the second phase of the formalin test. A higher dose of the D1 dopamine receptor antagonist, SCH23390 (0.1 mg/kg, intraperitoneal) also reduced swim stress-induced antinociception in both phases of the test. Exposure to 3 min water swimming stress, once daily for 3 days, induced tolerance to swim stress-induced antinociception in the second phase of the formalin test. Administration of sulpiride (12.5, 25 and 50 mg/kg), during exposure to water swimming stress (once daily for 3 days), decreased tolerance in the second phase, whereas the antagonist (12.5 and 50 mg/kg) increased pain scores in the first phase of the formalin test. Sulpiride (25 mg/kg) treatment however, once daily for 3 days with no water swimming stress, did not alter swim stress-induced antinociception (0.5, 1 and 3 min tests). Similarly, repeated treatment with SCH23390 (0.05 mg/kg) and water swimming stress did not alter tolerance induced by water swimming stress. Repeated administration of the antagonist in the absence of water swimming stress also did not change swim stress-induced antinociception. The results may indicate a possible involvement of both dopamine D1 and D2 receptors in the antinociception induced by swim stress and D2 receptor mechanism in the tolerance induced by repeated swim stress.
