RESUMEN
OBJECTIVE@#To determine the prevalence of seborrhoeic dermatitis (SD) and atopic dermatitis (AD) between the Demodex folliculorum (D. folliculorum) positive and D. folliculorum negative patients and to investigate any possible relationship between the D. folliculorum mites and the presence of SD and AD.@*METHODS@#In this cross sectional study, authors collected samples from the skin around the nasal tip of 180 randomized patients who reffered to Amir Al-Momenin Hospital dermatology clinic for skin erythema, scaling and pruritis, to examine the precence of demodicosis (D. folliculorum) infestation under optical microscope. Then authors assessed the prevalence of SD and AD between the D. folliculorum positive and D. folliculorum negative patients. Finally, data analysis using SPSS software and Chi-square test were performed.@*RESULTS@#Our study showed no significant association between the demodicosis (D. folliculorum) and SD (P=0.68) and AD (P=0.70) prevalence.@*CONCLUSIONS@#According to the result of this study, the eradication of Demodex mites probably is not effective to reduces the prevalence of both dermatitis. However further investigation on a larger scale in a case-control study in this area is recommended.

Objective: To determine the prevalence of seborrhoeic dermatitis (SD) and atopic dermatitis (AD) between the Demodex folliculorum (D. folliculorum) positive and D. folliculorum negative patients and to investigate any possible relationship between the D. folliculorum mites and the presence of SD and AD. Methods: In this cross sectional study, authors collected samples from the skin around the nasal tip of 180 randomized patients who reffered to Amir Al-Momenin Hospital dermatology clinic for skin erythema, scaling and pruritis, to examine the precence of demodicosis (D. folliculorum) infestation under optical microscope. Then authors assessed the prevalence of SD and AD between the D. folliculorum positive and D. folliculorum negative patients. Finally, data analysis using SPSS software and Chi-square test were performed. Results: Our study showed no significant association between the demodicosis (D. folliculorum) and SD (P=0.68) and AD (P=0.70) prevalence. Conclusions: According to the result of this study, the eradication of Demodex mites probably is not effective to reduces the prevalence of both dermatitis. However further investigation on a larger scale in a case-control study in this area is recommended.
RESUMEN
Background: Matridex is a filler containing hyaluronic acid polymers , hypermelosis and dextran that affects on the fibroblasts and macrophayes to induce soft tissue augmentation .The aim of this study was to evaluate the longevity and complications of Matridex for soft tissue augmentation in facial atrophic lesions
Materials and methods: Fifty patients with scars and wrinkles on the skin face were included in this study. The depth of the lesions was divided to 5 grades. Patients were re-evaluated 2 weeks, 3 and 6 months and 1 year after injection. Data were analyzed by SPSS software
Results: After 6 months, 78% had less absorption of the filler and after one year, 16% had still the filler in the treated area. There was significant difference between depth of the lesions before injection and 6 months and 1 year after treatment. After 6 months follow up 81.8 % had completely absorption in NLF area and 18.2% in glabella area. There was no significant difference between the volume of injection and absorption after 6 months, while there found significant difference after one year. There were no long- term complications and 16% showed short- term complications
Conclusion: Longevity of Matridex is between 6 months and one year in most patients. Some patients may have more than one year longevity. No serious complications were noted by using this filler
