Background and Aim: Acne is one of the most common diseases among young individuals. Controversial findings are reported about the effect of glycemic index (GI) and glycemic load (GL) of the diet on acne vulgaris. The aim of this study was to investigate the effect of GI and GL of diet on severity of acne.Methods: All relevant studies on effects of GI or GL on acne published up to December 2016 were collected using PubMed, Google Scholar, Science direct, Ovid and Cochrane library.Results: Of 714 articles in our initial research, 6 interventional and 3 case-control studies were included.Case-control studies revealed that patients with acne vulgaris consumed diets with a higher GI rather than control group. Intervention with a low GI diet reduced lesion counts and improved the severity of acne as well as insulin sensitivity compared with those under high GI diet.Conclusion: Overall, a diet with low GI and GL could improve acne severity and inflammatory lesions.

Background and Aim: Regarding the relatively high prevalence of depression in people with psoriasis, the present study was conducted to determine the role of type D personality and difficulties in emotion regulation in predicting the symptoms of depression in patients with psoriasis.Methods: This study was a descriptive correlational study. Among patients referred to the Dermatology Clinic of Razi Hospital in Tehran from November to January 2016, 60 patients with psoriasis were selected using available sampling method. The research instruments included type D Personality Questionnaire (DS-14 scale), Difficulties in Emotion Regulation Scale (DERS), and Beck Depression Inventory (Second Edition) (BDI-II). Finally, the data were analyzed using Pearson correlation coefficient and multiple regression tests.Results: The results of this study showed that there is a significant positive correlation between type D personality and difficulties in emotion regulation with symptoms of depression in patients with psoriasis (P<0.01). Regression analysis with enter method also showed that the two components of type D personality (negative affect and social inhibition), as well as two subscales (lack of emotional awareness and lack of emotional clarity) in difficulties in emotion regulation scale can predict the symptoms of depression in psoriasis.Conclusion: Type D personality traits and difficulties in emotion regulation can affect the psychological consequences of psoriasis, including depression in people with this disease.

Background and Aim: Psoriasis vulgaris is a chronic skin disease which is treated by many systemic or topical drugs. There is no cure for this disease and patients have to take medicaments for a long time, so having knowledge on adverse effects of current medicaments may prevent them and improve treatment process. The aim of this study was to evaluate the incidence of side effects of non biologic systemic drugs in psoriasis.Methods: In this observational study, we evaluated 200 hospital charts of patients with moderate to-severe psoriasis referred to dermatology clinics of Shohada and Loghman Hospitals in Tehran in 2016. SPSS statistical tools were used to determine the percentage of adverse events. Chi square was used to show the association of gender-related complications and student T-test to evaluate age-related complications.Results: %56 of patients were male, %26.5 were 25-34 year old, with mean age of 42±14.2 years and %83.5 of patients had no family history of psoriasis.11% of patients were hypertensive. Methotrexate was the most commonly used drug and the most common reported adverse event for it was increasing liver function tests (%6.2 in oral and %21.2 in IM injections). The most common reported adverse event for cyclosporine was increased blood pressure which was seen in 17 patients (15.3%). The most common side effect of acitertin was scaling, observed in 11 (%9.6) of patients. There was no relationship between age and sex of patients and development of side effects.Conclusion: This study showed systemic treatments for psoriasis can change laboratory biomarkers and cause skin eruptions.

Background and Aim: Body image is one of the main factors of self efficacy. This study aimed to investigate the relationship between body image and self-efficacy among female students in Hamadan University of Medical Sciences.Methods: This cross-sectional study was carried out on 408 female students of Hamadan University of Medical Sciences in 2017 with a stratified sampling method. To gather data, we used Multidimensional Body Self-Relation Questionnaire (MBSRQ) and general self-efficacy questionnaire and recorded demographic variables. Data were analyzed with SPSS-21 software using Pearson correlation and linear regression tests.Results: The dimensions of body areas satisfaction and illness orientation were evaluated at relatively desirable and moderate levels, respectively. Students' self-efficacy was also estimated at 60.05% of the mean score of the maximum achievable score at the moderate level. The results of regression analysis showed that the dimensions of the illness orientation, overweight preoccupation, fitness orientation, self-classified weight and appearance evaluation predicted the self-efficacy among the female students. In total, different dimensions of body image explained 14.1% of the variance of self-efficacy.Conclusion: We suggest providing training packages about body image dimensions improvement to enhance the selfefficacy of university female students.

Background and Aim: Trichotillomania (hair pulling disorder) is a chronic disorder, characterized by frequent hair pulling leading to hair loss. This disorder despite having multiple physical, economic and social consequences, is less likely to be diagnosed and treated. In the present study, we investigated the efficacy of emotion regulation therapy (ERT) on symptom’s severity, anxiety, depression, stress and quality of life in individuals with trichotillomania.Methods: Six patients were selected by available sampling method, and Massachusettes General Hospital (MGH-HPS) scale, Depression, Anxiety, Stress-DASS-21 scale, WHOQOL-26 Quality of Life questionnaire, and DERS Emotion Regulation questionnaire were used. Gross 8-session protocol (each session 90 minutes) was delivered on a weekly basis for each participant individually. Data were analyzed by visual analysis, percent of recovery, Freidman nonparametric test and Wilcoxon test.Results: ERT lead to significant reduction in symptoms of hair pulling, depression, anxiety, stress, difficulty in regulating emotion and improved quality of life in patients with trichotillomania.Conclusion: ERT significantly improves emotional problems and symptoms of hair pulling in the patients with trichotillomania. As a result, this treatment can be used as an effective treatment for this disorder.

Vitiligo is a common disorder in skin pigmentation and has an important role in patient’s quality of life. It may also cause severe emotional stress which makes its treatment necessary. As conventional therapeutic strategies are ineffective, there is an increasing tendency to use complementary medicine in the management of vitiligo. This article has been written with the aim of describing Iranian Traditional Medicine (ITM) approach to vitiligo mechanisms, prognosis and natural therapeutics. It is a product of a library study in the main ITM references and also related articles using mentioned keywords.According to ITM text books human body consists of four substantial humors, each has a very specific quality and quantity. Any excess or deficit of these humors may result in different disorders. Changing in phlegm humor and also improper function of “expulsive faculty” are the main causes of vitiligo from the viewpoint of ITM.

Recently, a new technology called nano-fractional radiofrequency has been developed in the treatment of skin rejuvenation. This novel technology can reduce side effects and recovery time due to the smaller pin size. The clinical trials have reported the effectiveness and safety of this new technology for treating many skin disorders such as rhytides, acne erythema, scarring, rosacea, striae and skin laxity. Despite its growing usage in aesthetic fields many clinical trials are needed to evaluate the effectiveness of this novel technology.
