Abstract
Background and Aim: Cutaneous drug reaction is a common side effect of antiepileptic drugs and a frequent cause of treatment discontinuation. These reactions ranges can be a mild maculopapular rash to Stevens-Johnson Syndrom and toxic epidermal necrolysis. Among the traditional anticonvulsant drugs the aromatic compounds Phenytoin, Phenobarbital and Carbamazepin have been associated with relatively higher incidences of cutaneous reactions which can hospitalized the patient. Some of the newer drugs also can induce this problem, especially lamotrigine.
Methods: All records of patiens who were hospitalized at hospitals related to Islamic Azad as well as Rasol Akram hospital with a diagnosis of cutaneous drug reaction to anticonvulsant therapy in 8 years period were reviewed.
Results: The most common culprit was phenytoin (32%) and the least common drug was lamotrigin (3%).
Conclusion: Cutaneous reaction to anticonvulsant drugs is common and sometimes may be life threatening which needs serious treatment options.

Abstract
Background and Aim: Hirsutism is defined as the presence of terminal hairs in androgen dependent areas like upper lip, cheeks, chin, breasts, lower area of abdomen and thigh in women. The aim of this study was to determine the etiologic factors and clinical features of hirsutism in premenopausal women.
Methods: In this cross-sectional study, 180 premenopausal women with hirsutism who were admitted at a referral dermatologic clinic in a 1-year period were investigated. After taking full medical history and performing physical examinations, a transabdominal ultrasonography of the ovaries, and laboratory evaluation including early morning total and free serum testosterone, prolactin, dehydroepiandrosterone sulfate, FSH, LH and 17-hydroxyprogestron in all patients were performed.
Results: The most common causes of hirsutism were idiopathic (51.1%), polycystic ovarian syndrome (37.7%), hyperprolactinemia (4.4%), adrenal hyperplasia (3.8%), and drug-induced (2.8%). Hirsutism was mild in 93 (51.6%) patients, moderate in 78 (43.3%) patients and severe in 9 (5%) patients. Family history of hirsutism was present in 100 patients. Clinical conditions associated with hirsutism were: acne (58.3%), obesity (55.5%), menstrual irregularity (38.8%), androgenic alopecia (17.7%) and acanthosis negricans (8.4%).
Conclusion: Idiopathic hirsutism and polycystic ovary syndrome were the most common causes of the hirsutism in premenopausal women. Obesity also had a significant role in hirsutism occurrence.

Abstract
Background and Aim: Vitiligo is a common pigmentary disorder that melanocytes are destroyed. Treatment of vitiligo depends on the extent of the disease and its distribution pattern. The aim of this study was to compare the efficacy of PUVA and NBUVB in patients with vitiligo.
Methods: A clinical trial has been performed on 60 patients with vitiligo referred to Bouali hospital and Mehrgan laser center in 1392 and treated with UVB and PUVA therapy methods. In first group treated with PUVA, oral tablets containing 8-methoxypsoralen were taken 3 hours before phototherapy twice a week. The second group was treated with NBUVB twice a week.
Results: In patients treated with PUVA, 40% and in patients treated with NBUVB, 43.3% were male. Seventeen (56.7%) of patients treated with PUVA had generalized vitiligo, 30% of them had segmental Vitiligo and 13.3% had focal Vitiligo. Seventeen (56.7%) patients that were treated with NBUVB generalized vitiligo, 30% had segmental and 10% had focal vitiligo. Repigmentation was significantly higher in patients treated with NBUVB than PUVA 3 and 6 months after initiation of treatment (P<0.05).
Conclusion: NBUVB is superior to PUVA in treatment complications and its recovery rate was acceptable.

Abstract
Today, the valuable metabolites of microalgae are widely used in the production of many cosmetic products, as the biomass of algae contains pigments, proteins, essential fatty acids, polysaccharides, vitamins and minerals, all of which are present in both natural foods and cosmetics are used. In fact, these secondary metabolites with anti-blemish and anti-microbial, anti-aging, sunscreen and skin whitening effects can repair and heal the skin and protect the skin from UV damage and prevent inflammation. Existing cosmetics can in many cases be replaced with microalgae-derived cosmetics that are environmentally friendly as well as safe. The effects of microalgae and their derivatives have been tested in various nutritional studies around the world. However, there are very few studies on their cosmetic applications, so in this review article we tried to study several species of microalgae, cultivation methods, use of biomass and bioactive molecules derived from microalgae in the production of anti-aging products, sunscreen and skin whitening in the formulation of cosmetic compounds.

Abstract
One of the most important functions of the skin is to protect against various stressors. Environmental stimuli such as UV and environmental pollution increase reactive oxygen species and cause wrinkles and skin aging. Skin aging is associated with decreased collagen production and decreased activity of enzymes involved in collagen structure. Moisturizing chemicals increase the skin's ability to retain water, but long-term use can have adverse effects on human skin, such as allergies and even tumorigenic effects. As a result, the use of biological resources, especially photosynthetic organisms such as cyanobacteria, as safe alternatives is increasing. The mechanism by which cyanobacteria respond to ultraviolet radiation is the synthesis of ultraviolet compounds such as mycosporin-like amino acids and scytonemin. In addition, the exopolysaccharides produced by some species that live in extremely dry habitats can be used as moisturizers in cosmetics. In this study, we introduce the potential of cyanobacterial metabolites as alternative sources for sunscreens and moisturizers.

Abstract
Microalgae are photosynthetic microorganisms which are the result of permanent exposure to stressful conditions such as high or low temperature, high salinity, osmotic pressure, ultraviolet radiation (uv), contain valuable bioactive compounds in cosmetic products .the existing cosmetic products can be replaced with the cosmetic products that are compatible with the environment and can be included in the topical formulations of skin care such as moisturizers, Anti-wrinkles, anti - aging and anti - acne. In addition, the extracts from these microalgae are used to make sunscreen to treat skin pigmentation and improve wounds; therefore most commercial cosmetics have a wide range of natural compounds extracted from cyanobacteria and this leads to increasing antioxidant, regenerative, moisturizer, shielding and brighteners for both hair and skin. In this article the cosmetic use of cyanobacteria extract and dried powder in improving the appearance and health skin have been investigated. Furthermore, analyzing the brand of Spirulina has been discussed.

Abstract
Microalgae are a diverse group of photosynthetic eukaryotic and prokaryotic microorganisms in different shapes and sizes that have evolved by being in stressful conditions and have devised mechanisms to maintain their survival. The production of unique biochemical compounds called bioactive compounds is one of these mechanisms. These compounds restore and heal the skin and protect the skin from damage caused by various factors, and in many cases these products are used in the treatment of diseases and cosmetic formulations. Today, cosmetic products derived from microalgae, which are environmentally friendly and safe, replaced the products in the market. In this review article, the potential of many species of microalgae and their derived bioactive molecules in the production of cosmetics is discussed. In addition to that, by presenting the current microalgae products in the global cosmetics market, it highlights the importance of these organisms in the use of microalgae in the production of quality cosmetics, and finally by providing suggestions such as encapsulating pigments to increase resistance and the stability of pigments envisages their greater use in the cosmetic industry in the future.

Abstract
Worldwide, 16,000 deaths occur daily due to wound injuries, leading to increased concern in low- and middle-income countries. Today, with the increasing demand of consumers to use natural biological compounds instead of using harmful and carcinogenic chemical compounds, algae were introduced to the market as an effective clinical skin alternative. In fact, ease of cultivation and low nutritional requirements make algal polysaccharides an attractive alternative for advanced wound dressings. Micro and macroalgae are a new source of biological saccharide polymers for wound healing. The hydrophilic nature of these polymers due to their capacity to trap water molecules in their structure makes hydrogels that have a high ability to absorb and release liquid. In this review article, by studying the latest articles, some algae polysaccharides that are widely used as wound healing dressings such as alginates, fucoidans, carrageenans, laminarin, agar-agar and olvan are discussed. These compounds are not only used as functional biomaterials for controlled drug delivery, but also for cell stabilization and preparation of scaffolds for tissue engineering.
