Background: There is still no certain effective treatment for vitiligo as a common chronic skin disorder characterized by depigmented patches and loss of skin melanocytes., Objectives: This study evaluates the efficacy of oral silymarin combined with hair follicle transplantation compared to follicle transplantation alone in the treatment of refractory vitiligo., Materials and Methods: Twenty refractory vitiligo patients were enrolled in this randomized controlled clinical trial, following up for 3 months. One group underwent hair transplantation plus oral silymarin, while the other group underwent follicle transplantation alone. We assessed the progress with Vitiligo Extent Tensity Index (VETI) in both groups and the peri-follicular pigmentation diameter was estimated monthly. The Friedman test for comparing two groups at the end and the Mann-Whitney test for comparing two groups during each month was used., Results: The mean age was 30.22 (18-59) years, with the male to female ratio of 1:1. The decrease in the VETI and increase in the perifollicular pigmentation was statistically significant between silymarin and another group in monthly follow-up (p-value: 0.019, 0.019, and 0.035, respectively). Finally, the re-pigmentation was notable in silymarin group (p-value <0.001 vs. 0.029, respectively). In addition, both genders had a significant increase in peri-follicular re-pigmentation in the last follow-up (p-value: 0.012 and 0.044, respectively); although the improvement was not statistically significant between genders in each month., Conclusion: According to our study, silymarin in combination with hair transplantation could be a potential medical treatment for vitiligo; however, further trials are needed to establish the efficacy of combination therapies., (© 2024 The Author(s).

Objective: Cutaneous Leishmaniasis (CL) is one of the highly prevalent endemic diseases in the Middle East. The disease is a complex skin infection imposing a heavy burden on many developing countries. This study aimed to evaluate the impact of adding oral fluconazole to topical cryotherapy on the treatment efficacy and time to achieve complete recovery of CL lesions., Method: This triple-blind randomized clinical trial included 52 participants with CL. Participants were allocated to receive either weekly cryotherapy with liquid nitrogen and oral fluconazole at a dose of 6 mg/kg daily at a maximum of 400 mg for 6 weeks as the interventional arm or weekly cryotherapy with liquid nitrogen plus the placebo for the same period of 6 weeks as the control arm., Results: Fifty-two eligible participants enrolled the study, with a CL lesion count of 1 to 8 (mean 1.96), and served as the interventional (n = 28) and control (n = 24) arms. The trend of the mean surface area of the lesions was significantly decreasing in both arms (P < 0.001), with no statistically significant difference between arms (P = 0.133) or all assessed time point pairwise comparisons (P > 0.05). There was no significant difference between the treatment arms in terms of the end-point recovery status (P = 0.491) or the frequency of post-treatment secretion (P = 0.437). No adverse effect was observed., Conclusion: Despite a slightly higher reduction in the lesion surface in the cryotherapy and fluconazole treatment arm, the addition of fluconazole did not provide statistically significant therapeutic value to cryotherapy in the treatment of CL. However, with adjustment for the initial lesion size, the efficacy of the regimen in the interventional arm was more pronounced, though it was still insignificant., (© 2024. The Author(s).)

Introduction: With increasing age, patients' facial volume decrease. For this reason, nano fat grafting has recently gained popularity as adjunctive treatment to facial rejuvenation procedures. However, few quantitative studies have been conducted to investigate the impact of nano fat on facial wrinkles., Aims: In the present study, authors aim to investigate the therapeutic effect of intradermal injection of nano fat on fine facial wrinkles and assess their changes over 7 months of follow-up., Methods: In this randomized trial, 15 patients with fine facial wrinkles were enrolled. The fat was harvested from the abdomen and processed into nano fat. Nano fat was injected into the facial wrinkles intradermally with a needle of 27 gauge. The patients were evaluated before and 7 months postinjection utilizing Visio face 1000D (CK electronic, manufactured in Germany); and four parameters of wrinkles (area, volume, depth, and percent area) were evaluated before and after the nano fat injection., Results: Our evaluation with Visio face showed that nano fat injection was significantly reduced the volume, area, depth, and percent area of wrinkles after 7 months of follow-up without serious long-lasting adverse effects. Moreover, wrinkles with higher percent area, depth and volume loss show greater improvement after the treatment. Our results also indicate that males and females equally benefit from this treatment except for the percent area parameter that was improved more significantly in male patients., Conclusion: Our study showed that intradermal injection of nano fat significantly decreases the volume, area, depth, and percent area of fine facial wrinkles. Further quantitative studies with control groups and larger sample sizes are required., (© 2023 The Authors. Journal of Cosmetic Dermatology published by Wiley Periodicals LLC.)

Background and Aim: Vitiligo is an autoimmune skin disorder characterized by circumscribed depigmented macules and patches caused by the loss of functional melanocytes. Although there is no definitive treatment for vitiligo, several treatment options have been associated with relative satisfactory outcomes. The purpose of this study was to compare the efficacy of micro-needling in conjunction with topical 5-fluorouracil (5-FU) versus topical tacrolimus ointment in treating vitiligo patches., Patients and Methods: This study included nineteen participants, each of whom received both treatments on two randomly selected vitiligo patches of approximately the same size and location. On one patch, a combination of weekly micro-needling and topical application of 5-FU solution was used every other day, while on the other, 0.1% tacrolimus topical ointment was applied twice daily. The G-score was used to compare treatment outcomes after 3 months., Results: The median duration of the disease in our population was 7 years. Six patients (32%) in the micro-needling plus topical 5-FU treated group showed a moderate to excellent response, indicating a significant improvement between both treatments (p-value = 0.019). In contrast, all other patches treated with topical tacrolimus showed poor improvement. Lower extremity and trunk responded more to treatment with micro-needling plus topical 5-FU than upper extremity and acral areas. Moreover, none of those who have had the disease for more than ten years have responded to treatment. Mild erythema, pinpoint bleeding, and irritation were detected only in the micro-needling treated group., Conclusion: The current study showed that using micro-needling in conjunction with 5-FU could treat vitiligo patients more efficiently than tacrolimus monotherapy. Despite showing moderate to excellent improvement in patches treated with micro-needling and 5-FU, this well-tolerated office-based modality still requires additional research., (© 2022 The Authors.

Background: Genetic diversity in human leukocyte antigen (HLA) alleles across populations is a significant risk factor for drug-induced severe cutaneous adverse reactions (SCARs), e.g., carbamazepine (CBZ)- and lamotrigine (LTG)-induced Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN). The present study aimed to investigate the frequency of different HLA alleles in Iranian patients with CBZ- and LTG-induced SJS/TEN., Methods: A case-control study was conducted from 2011 to 2018 at various hospitals affiliated with Shiraz University of Medical Sciences (Shiraz, Iran). A total of 31 patients receiving anticonvulsant drugs (CZB or LTG) were recruited and divided into two groups. The drug-induced group (n=14) included hospitalized patients due to CBZ- or LTG-induced SJS/TEN. The drug-tolerant group (n=17) included individuals receiving CBZ or LTG for at least three months with no adverse effects. In addition, 46 healthy individuals (control group) were recruited. The frequency of HLA-A, -B, and -DRB1 alleles in patients with CZB- or LTG-induced SJS/TEN was investigated. HLA typing was performed using the allele-specific polymerase chain reaction method. The Chi square test and Fisher's exact test were used to determine a potential association between SJS/TEN and HLA alleles. P<0.05 was considered statistically significant., Results: CBZ- or LTG-induced SJS/TEN was not significantly associated with HLA alleles. However, HLA-DRB1*01 showed a significantly higher frequency in patients with CBZ-induced SJS/TEN than the CBZ-tolerant patients (30% vs. 9%, P=0.07)., Conclusion: Overall, no significant association was found between CBZ- or LTG-induced SJS/TEN and HLA alleles. Further large-scale studies are required to substantiate our findings., Competing Interests: None declared., (Copyright: © Iranian Journal of Medical Sciences.)

Objective: Melasma is an acquired and chronic hyperpigmentation disorder associated with a negative impact on patients' quality of life. This study compares the efficacy of 100mg/mL intradermal TA with 4% topical HQ on female patients presenting with melasma lesions., Methods: In this randomized double-blind controlled trial, 48 women with melasma were allocated into two groups, treated with either 100mg/mL intradermal TA or topical 4% HQ. The MASI (Melasma Area and Severity Index) score was assessed by paired t-tests and repeated measured ANOVAs. The Dynamic Physician General Assessment (PGA) was also performed by taking photographs with a digital camera., Results: The average MASI score for the HQ and TA groups was 7.7 (3.0 SD) and 5.9 (2.5 SD), respectively. In both groups, the MASI decreased significantly after three months of treatment; however, the decrease was not significant between the two groups ( P =0.1). All participants developed mild degrees of burning pain in the injection site without serious adverse effects., Limitations: First, we only used the MASI score to measure melasma degree. Second, this is a single-center study with a small sample size. Third, the before-after photos were not taken with a high-quality camera., Conclusion: The results of our study showed that both TA and continuous HQ significantly reduced the MASI score of patients without any significant differences and serious side effects. Although many treatment modalities are available for melasma, this condition is still challenging for dermatologists with a high recurrence rate after treatment., Competing Interests: DISCLOSURES: The authors report no conflicts of interest relevant to the content of this article., (Copyright © 2023.

Background and Aims: Melasma is a common dermatologic disorder characterized by symmetrical hyperpigmented lesions on the face. Although various therapeutic options are available for melasma, its treatment remains challenging. The present study evaluated the safety and efficacy of intradermal microinjection of tranexamic acid (TA) plus ascorbic acid in treating melasma lesions compared with TA and placebo., Methods: From September 2019 to May 2020, 24 patients with symmetrical melasma were enrolled in a prospective, double-blind, split-face, randomized controlled clinical trial. Each patient received 50 mg/ml TA and 50 mg/ml ascorbic acid for one side of the face (A) and 50 mg/ml TA and placebo for the other side (B) every 2 weeks for 12 weeks. The Melasma Area and Severity Index (MASI) score, Physician Global Assessment, and pain were measured at baseline and at 4, 8, 12, and 24 weeks. Statistical analysis was done using SPSS software version 16, and data were reported as mean ± standard deviation or median and interquartile range. χ 2 and Fisher's exact tests were used to test differences between the groups., Results: Both groups experienced a significant decrease in MASI scores compared with the baseline. The MASI score was significantly less in the intervention group than the placebo group at the 8th and 12th weeks. However, burning pain was significantly more prominent in the intervention group., Conclusion: Intradermal injection of ascorbic acid combined with TA can be beneficial in treating melasma. Currently, there are numerous treatment modalities for melasma. However, the results still vary, and satisfactory outcomes are yet to be reached., Competing Interests: The authors declare no conflicts of interest., (© 2022 The Authors.

Background: Acne vulgaris is a common inflammatory disease of the pilosebaceous follicle that affects many teenagers and young people. There is an obvious need for topical treatments with good tolerability and efficacy for the management of acne lesions., Objective: This study determined the therapeutic efficacy of topical sodium hypochlorite solution (0.005%) in the treatment of mild to moderate acne lesions., Methods: This placebo-controlled randomized controlled trial compared 0.005% sodium hypochlorite to placebo administered topically on each side of the patients' faces 3 times a day for 1 month. The numbers of papules and pustules were recorded at baseline, 1, 2 and 4 weeks after initiation., Results: The total number of papules and pustules decreased after topical application of sodium hypochlorite 0.005% for 1 month., Conclusions: Topical sodium hypochlorite solution (0.005%) can be effective in the treatment of mild to moderate acne, and its clinical efficacy was evaluated between the male and female groups and between the hormonal and non-hormonal ones., Trial Registration: Our study was registered in the Iranian Registry of Clinical Trials (IRCT) with the code number IRCT20200701047976N1., Competing Interests: Competing interests: The authors have no conflicts of interest to declare., (©2021 Dorostkar et al.)

Psychodermatology is an interdisciplinary field in dermatology which involves the interaction between mind and skin. Studies from various parts of the world demonstrate generalized lack of knowledge regarding psychocutaneous disorders among dermatologists. We provide this survey to evaluate the knowledge, awareness, and practice patterns of Iranian dermatologists about psychodermatology. A survey questionnaire on the topic of this study was randomly distributed among Iranian dermatologists in a national dermatology conference and also by mail. All collected data were entered into SPSS software version 20.0 and were analyzed using descriptive statistics. The questionnaires were filled out by 65 dermatologists aged 30 to 60 years. From this group, 60% (39) were male and 40% (26) were female. About 86% of the dermatologists saw more than 30 psychodermatology patients weekly and about 43% mentioned they felt somewhat comfortable managing psychodermatology patients. Alopecia, vitiligo, and acne were the most common primary dermatology diseases with secondary psychiatric problems. More than half of our responders mentioned that they did not take any psychodermatology courses during their training program. However, about 66% of the dermatologists expressed interest in participating in psychodermatology continuing medical education programs. Further collaboration between dermatologists and psychiatrists can shape a brilliant future in psychodermatology and improve the quality of life of patients. We highly recommend educational courses in psychodermatology for both dermatologists and psychiatrists., (© 2020 Wiley Periodicals LLC.)

Purpose: Vitiligo is an acquired hypopigmentation condition in which well-defined macules can develop virtually everywhere on the patients' skin. This analytic case-control study was conducted in Faghihi Hospital outpatient dermatology clinic, affiliated to Shiraz University of Medical Sciences, southern Iran from June to September 2019. Furthermore, we studied the relationship of hypertension with activity, age of onset, duration, affected body surface area and type of vitiligo., Patients and Methods: In the current case-control study, 166 individuals were enrolled in total (the case group was comprised of 83 vitiligo patients and 83 individuals actedas control group). The case group was made up of vitiligo patients (both segmental and non-segmental) between 20 and 50 years of age, no prior history of systemic disease and other hypopigmentation disorders, while individuals with any form of dermatologic findings were excluded from the control group. Individuals aged younger than 20 years old or older than 50, having a dermatologic disease other than vitiligo, being afflicted with the diseases which may lead to secondary hypertension, pregnancy, taking substances, and medication which can lead to hypertension were chosen as the exclusion criteria in this study., Results: Data obtained from our study revealed that vitiligo patients had a higher prevalence of essential hypertension diagnosis than the control group ( P =0.040). Also, no significant relationship was found between patients' age at the first lesion appearance ( P =0.856), duration of vitiligo involvement ( P =0.497), and percentage of vitiligo involvement ( P =0.681) with hypertension., Conclusion: According to our results, vitiligo patients were more susceptible to hypertension while no association could be found between characteristics of the disease and rise in blood pressure., Competing Interests: The authors report no conflicts of interest in this work., (© 2020 Namazi et al.)

Cutaneous injury can ignite excessive fibroproliferative growth that results in keloid formation. Keloids are associated with significant morbidity related to disfigurement and/or symptoms (e.g., pain and pruritus). First-line treatment of formed keloids involves topical or intralesional steroids. Recurrent or resistant keloids are managed by surgical excision or cryotherapy, followed by steroidal application or adjuvant irradiation. Although adjuvant irradiation appears to be most efficacious, alternative therapeutic options are needed for patients without access to radiation centers. Botulinum Toxin A (BTA) appears to have similar inhibitory effects to irradiation on the cell cycle via downregulation of pathogenic cytokines. Herein, we conducted a study to compare the efficacy of intralesional triamcinolone used alone, or in combination with BTA, in the treatment of formed keloid scars. Twenty patients with a cumulative of 40 keloids completed the study. There was no significant difference between treatment arms with respect to height vascularization, pliability, and pigmentation scores. The addition of BTA resulted in significant symptomatic improvement of pain and pruritus as compared to intralesional triamcinolone alone (p < 0.001). Irradiation is only effective when administered in the adjuvant setting where inhibitory effects on cell cycle and migration are optimized. Future studies with intralesional triamcinolone and BTA should be performed adjuvantly., (© 2018 Wiley Periodicals, Inc.)

Background: The percent and distribution of body fat are important factors in the pathogenesis of numerous diseases. Our aim was to investigate common anthropometric indices in their relationship with body fat content., Methods: In a cross-sectional study 1360 healthy individuals (580 men and 780 women) in a cluster sampling, from Ahvaz, Iran, body fat content (using bioelectrical impedance) and anthropometric measurements [weight, waist circumference, a body shape index, abdominal volume index, body adiposity index, conicity, body mass index, hip circumference, waist to hip ratio and waist to height ratio] was obtained. The ROC curve analysis was used to compare each index with body fat percent., Results: Significant difference was found between men and women in all anthropometric parameters (p < 0.001). Women displayed higher percentages in the overweight and obese categories (33.6% vs. 32.9% and 26.4% vs. 22.1%, respectively). In both men and women, the strongest correlations were seen between body fat percent and BMI, AVI and WHtR (r>7.9 and p<0.001). BMI, WHtR and AVI in men and BAI, BMI and WHtR in women showed the most accuracy for estimating body fat percent, respectively., Conclusion: All anthropometric parameters could predict body fat percent with relatively good power, however BMI, WHtR and AVI are more powerful predictors. Based on our findings, we suggest using the AVI and WHtR instead of other indexes, as they are better able to assess the accumulation of fat in the abdominal area and are able to more accurately assess body fat percent, which are indicators of chronic disease., (Copyright © 2016 Diabetes India.

In this study we evaluated and redefined the optimum body mass index (BMI) cut-off point for the Iranian population based on metabolic syndrome (MeS) risk factors. We further evaluated BMI cut-off points with and without waist circumference (WC) as a cofactor of risk and compared the differences. This study is part of the largest surveillance programs conducted in Shiraz, Iran, termed the Shiraz Heart study. Our study sample included subjects between the ages of 20 to 65 years old. After excluding pregnant women, those with missing data and those with comorbid disease, a total of 12283 made up the study population. The participants underwent a series of tests and evaluations by trained professionals in accordance with WHO recommendations. Hypertension, abnormal fasting blood sugar (FBS), triglyceride (TG) and high density lipoprotein cholesterol (HDL) (in the context of the definition of metabolic syndrome) were prevalent among 32.4%, 27.6%, 42.1 and 44.2% of our participants, respectively. Women displayed higher rates of overall obesity compared to men (based on the definition by the WHO as higher than 30 kg/m2). Regarding MeS, 38.9% of our population had the all symptoms of MeS which was more prevalent among women (41.5% vs. 36%). When excluding WC in the definition of MeS, results showed that males tend to show a higher rate of metabolic risk factors (19.2% vs. 15.6%). Results of multivariate analysis showed that parallel to an increase in BMI, the odds ratio (OR) for acquiring each component of the metabolic syndrome increased (OR = 1.178; CI: 1.166-1.190). By excluding WC, the previous OR decreased (OR = 1.105; CI: 1.093-1.118). Receiver Operating Characteristic (ROC) curve analysis showed that the optimum BMI cut-off point for predicting metabolic syndrome was 26.1 kg/m2 and 26.2 kg/m2 [Accuracy (Acc) = 69% and 61%, respectively)] for males and females, respectively. The overall BMI cut-off for both sexes was 26.2 kg/m2 (Acc = 65%) with sensitivity and specificity of 69% and 62%, respectively. This cut-off had a positive predictive value of 54% and a negative predictive value of 76%. When we excluded waist circumference, the optimum BMI cut-off for acquiring metabolic risk factors in males decreased to 25.7 kg/m2 (Acc = 67%) and increased for women to 27.05 kg/m2 (Acc = 66%). Iranians are at higher risks of morbidity related to metabolic factors at a lower BMI cut-off and prompt action and preventive health policy are required to prevent and educate Iranians regarding diseases associated with obesity.

The marginal zones of the Caspian Sea and the Persian Gulf have a higher prevalence of thalassemia compared to other regions of Iran. This disease has disabled many people and resulted in increasing health care costs. The aim of this study was to assess the incidence of β-thalassemia (β-thal) and to evaluate the outcome of applied preventive strategies over a 14-year period in Fars Province, Southern Iran. This cross-sectional study comprised all new cases of β-thal recorded during 1997-2011. The data were obtained from the Non-Communicable Diseases Surveillance Department of Shiraz University of Medical Sciences, Shiraz, Iran, and are presented as mean ± standard deviation (SD). The Fars Health Network System screened 840 686 males and females applying for marriage certificates. Among the carriers, 50.5% cancelled their marriages, 42.5% married, and 7.0% did not show up at the clinics. The rate of cancelled marriages has reduced since 2000, when marriage candidates were given the option of prenatal diagnosis. From 2000 to 2011, a total of 3539 married couples were referred for prenatal diagnosis. Of these, 806 fetuses were found to carry thalassemia and 800 aborted. It is impressive to note that while 101 cases of thalassemia were recorded in 1997, this figure was reduced to two cases by 2011. This study has established that an integrated primary health care approach, with good infrastructure for implementing successful strategies, can significantly reduce the incidence of β-thal.

Objectives: Effective assessment of tissue perfusion is highly important during Coronary Artery Bypass Graft (CABG). Mixed venous O2 saturation (Svo2) is one of the best and routinely used markers of tissue perfusion. However, this method is costly and leads to considerable complications. Thus, the present study aimed to determine whether the Svo2 can be substituted with central venous saturation (Scvo2) and if there is any correlation between lactate level and Svo2., Methods: This prospective observational study was conducted on 62 patients scheduled for CABG. After induction and maintenance of anesthesia, blood samples drawn from central venous, pulmonary artery, and radial artery were used to measure Scvo2, Svo2 and serum lactate level respectively before and after Cardio Pulmonary Bypass (CPB). Pearson's correlation test was used to determine the correlation between Svo2 and Scvo2 as well as between Svo2 and serum lactate level. Besides, P < 0.05 was considered as statistically significant., Results: Overall, 62 Patients, 33 males (53.2%) and 29 females (46.8%) were enrolled into the present study. The most common coexisting illness was hypertension detected in 33 patients (53.2%) followed by hypercholesterolemia in 28 ones (44.4%). In this study, Svo2 was positively correlated with Scvo2 (r = 0.63, P < 0.001). However, no correlation was found between Svo2 and lactate (r = 0.124, P = 0.348)., Conclusions: In summary, Scvo2 is considered as the best substitute of Svo2 for detecting tissue hypo perfusion during CPB. Although the lactate level had been considered as an appropriate marker of tissue perfusion and ischemia, it was not correlated to Svo2 during CABG.
