- چکیده انگلیسی: Background: Lichen planus (LP) is a common inflammatory skin disease. Pathogenesis of LP includes two possible mechanisms; related or unrelated to antigen. Regarding different clinical features of cutaneous and mucosal types of LP, for the first time, we decided to perform a qualitative and quantitative study of immune cells in different types of cutaneous LP and in comparison with normal skin. Methods: A total of 88 specimens (60 cases of cutaneous LP, 28 cases of normal skin) were selected from 2016 to 2017 in Kerman, Iran. Evaluation of immune cells was carried out based on qualitative and quantitative analysis. These findings were statistically calculated by descriptive statistical tests including frequency and mean ± standard deviation. Quantitative data were analyzed by independent t-test, chi-square, and analysis of variance (ANOVA). Data were analyzed using SPSS16 (SPSS Inc., Chicago, IL, USA). A p value less than 0.05 was considered statistically significant. Results: Our study demonstrated that the mean number of immune cells was significantly higher in lichen planus group in comparison with the control group. Number and staining intensity of Langerhans cells (LCs) in the LP group were significantly greater in epidermal than dermal region. Mastocytes were located mostly within the deep dermis in the LP group. Hypertrophic and atrophic LP had the highest and the lowest number of immune cells (i.e., mastocytes, LCs, and CD3 positive cells), respectively, with a significant difference. Conclusion: Our study demonstrated that immune cells were seen in larger numbers in the hypertrophic type of cutaneous LP which is consistent with the chronicity of this disease.

- چکیده:
- چکیده انگلیسی: PHACES syndrome (Posterior Fossa Malformations, Hemangioma, Arterial Anomalies, Cardiac Defects and Coarctation of the Aorta, Eye Abnormalities, and Sternal Abnormalities or Ventral Developmental Defects) is a rare neurocutaneous syndrome, which characteristic feature is large segmental hemangioma. Extracutaneous involvement is an important cause of morbidity in this syndrome.
Described below is an infant with large hemangiomatous lesions on the right side of the face, suprasternal notch, midline sternal defect and supraumbilical raphe. Based on the new consensus on the diagnostic criteria of PHACES syndrome, a definitive diagnosis of PHACES syndrome has been corroborated. Accordingly, our patient was analyzed with regards to other clinical features through magnetic resonance imaging of the head, neck and abdomen, all of which were normal. In echocardiography, the patient showed atrial septal defect, in addition to ipsilateral conductive hearing loss, contralateral cataract and Horner’s syndrome, which was reported only in very few cases. The clinical presentation of the present case was different from most previous reported ones, as segmental hemangioma in PHACES syndrome was, for the most part, located on the left side of the face and ocular involvement was predominantly reported ipsilateral to hemangiomatous lesion.- انتشار مقاله: 27-09-1398

- چکیده:
- چکیده انگلیسی: Investment decision making is one of the key issues in financial management. Selecting the appropriate tools and techniques that can make optimal portfolio is one of the main objectives of the investment world. This study tries to optimize the decision making in stock selection or the optimization of the portfolio by means of the artificial colony of honey bee algorithm. To determine the effectiveness of the algorithm, its sharp criteria was calculated and compared with the portfolio made up of genes and ant colony algorithms. The sample consisted of active firms listed on the Tehran Stock Exchange from 2005 to 2015. The sample selected by the systematic removal method. The findings show that artificial bee colony algorithm functions better than the genetic and ant colony algorithms in terms of portfolio formation
