- چکیده انگلیسی: Background: Acne vulgaris is one of the most common inflammatory skin diseases. Topical antibiotics and retinoids are the first-line therapy in mild to moderate acne vulgaris. Due to increased resistance of Propionibacterium acnes (P. acnes) to topical antibiotics, searching for new formulations of drug release such as niosomes is considered in order to increase efficacy and decrease drug resistance. This study compared the efficacy of niosomal erythromycin4% versus combination of erythromycin 4% and zinc acetate 1.2% in the treatment of mild to moderate acne vulgaris.
Methods: In this double-blind clinical trial, 70 patients with mild to moderate acne vulgaris of both genders aged between 12 to 30 years were included. The patients were evaluated by counting of the lesions and assessment of quality of life during the 2nd, 4th, 8th and 12th weeks.
Results: At the end of the study, 40% and 66.6% of the patients in niosomal erythromycin group showed a reduction in the number of non-inflammatory and inflammatory lesions, respectively. These percent for erythromycin and zinc acetate group were 46.6% and 63.3%. One hundred percent of excellent response (8 out of 30 patients) was observed in niosomal group (P=0.002). A significant improvement in the quality of life was also observed in niosomal group (P=0.001). Side effects were much less severe in the niosomal group than control group.
Conclusion: The results showed that niosomal erythromycin has higher efficacy and less severe side effects in comparison with combination of erythromycin and zinc acetate.- انتشار مقاله: 07-04-1397

- چکیده:
- چکیده انگلیسی: Background & Objective:Basal cell carcinoma (BCC) is classified into BCC1 or low risk (nodular, superficial type) and BCC2 or high risk (micronodular, morpheaform, infiltrative, and basosquamous types) based on clinical behavior. This study attempts to evaluate immunohistochemical (IHC) findings and clinical features associated with local aggressiveness and recurrence in BCC lesions.
Methods:This is a cross-sectional descriptive study conducted on 42 paraffin blocks (22 BCC1, 20 in BCC2) at Pathology Department of Afzalipour Teaching Hospital. First, demographic features of the patients were recorded and pathology blocks were classified by two dermatopathologists based on histopathological types of BCC1 and BCC2. Then, primary monoclonal antibodies including CD10, CD1a, SMA, Ki67, CD34, and P53 were utilized for IHC study. We compared BCC1 and BCC2 according to IHC markers, demographic features of patients, and tumoral features.
Results:The mean number of Langerhans cells (LCs) within epidermis above tumor mass was 14+1.92 and 4.7±1.23 in BCC1 and BCC2, respectively; these results show a significant difference between the two groups (P=0.001). P53 was positive in 41.13±6.39% and 74.5 ±6.26% of the tumor cells in BCC1 and BCC2 groups, which was statistically significant (P=0.001). Also, the mean number of blood vessels was 14.40±1.30 and 21.40±1.97 in BCC1 and BCC2, that was statistically significant (P=0.005).
Conclusion: Higher numbers of angiogenesis (SMA positive) and positive P53 were observed in BCC2 than BCC1. Also, more active positive CD1a cells were observed in BCC1 compared to BCC2.- انتشار مقاله: 20-12-1396

- چکیده:
- چکیده انگلیسی: Background: Atopic dermatitis is the most common inflammatory skin disease in children. Severe itching may lead to an impaired quality of life in the patients. In this study, we evaluated the validity and reliability of Persian version of a questionnaire regarding the infants’ dermatitis quality of life in children suffering from atopic dermatitis.
Methods: When the original authors approved of the Persian version of the questionnaire, the parents completed the questionnaire for their 98 children with atopic dermatitis aged less than four years. We analyzed the data by SPSS 16. Cronbach’s alpha and inter-item and calculated the correlations to evaluate the reliability and validity via Kaiser criterion and scree plot.
Results: The calculated mean score of questionnaire was 9.65±5.41. The first (itching and scratching) and eight questions (treatment problems) obtained the highest and lowest scores, respectively. There was a strong, positive correlation between the severity of the disease and the quality of life score in the patients. Cronbach’s alpha was calculated as 0.88 which is a sign of good internal consistency of the items. The inter-item correlative coefficients varied between -0.004 to 0.87. We used Kaiser’s criterion and scree plot to evaluate the validity and achieve a two-factor solution.
Conclusion: Persian version of infants’ dermatitis quality of life index questionnaire was valid and reliable.- انتشار مقاله: 20-05-1398

- چکیده:
- 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
