[ 1 ] - بررسی خصوصیات بیوفیزیکی و روش‌های تصویربرداری پوست (بخش دوم)
Great progress in optics, electronic engineering, and computer science provide an opportunity to diagnosis of skin diseases, estimating effectiveness of drugs and skin care products using non-invasive, non-destructive methods of analysis. Also many noninvasive methods using analytic devices are developed to assessment of the outcomes of dermatologic surgeries on malignant skin tumors. The aim o...
[ 2 ] - درمان سلولیت و چاقی موضعی با امواج آکوستیک (AWT): معرفی سه بیمار و پروتکل استفاده‌شده
There are different ways to treat local obesity and cellulite including invasive and noninvasive methods. Due to the fact that noninvasive methods have significantly lower rates of adverse effects, they become more popular. One of these methods is acoustic wave therapy (AWT) or shock wave therapy (SWT). In addition to treating cellulite, SWT has been found useful for some other conditions. In t...
[ 3 ] - بررسی خصوصیات بیوفیزیکی و روش‌های تصویربرداری پوست (بخش اول)
Skin is the largest organ of the integumentary system with multiples important functions. Due to its complex structure, the permeability skin status can be modified by different external and internal factors such as chemical and physical stresses, and several skin and systemic diseases. Today, different non-invasive methods are used to assess the skin barrier biophysical properties. The paramet...
[ 4 ] - Comparative clinical assessment of two nasolabial hyaluronic acid fillers: A double-blind, randomized controlled trial
Background: Various fillers have been used for the correction of nasolabial folds. This study investigated the efficacy and safety assessment of two hyaluronic acid (HA) fillers on moderate nasolabial folds. Methods: This study randomized 10 volunteers, aged 35 to 49 years, with moderate nasolabial folds. Volunteers received injections of HA A and HA B gels into the right or left skin folds. Th...
[ 5 ] - Sarcoidal Type Foreign Body Reaction: A Case Report
Sarcoidosis and foreign body reactions are common differential diagnoses of skin granuloma formation. We report a 40 year –old man with sarcoid type granulomas containing polarized foreign materials, and also bilateral hilar adenopathy. It appears that detection of foreign bodies in histopatologic studies of granulomas does not necessarily exclude the possibility of sarcoidosis.
[ 6 ] - Frequency of false positive responses in patients with multiple positive reactions in patch test
Background and aim: Contact dermatitis is an inflammatory skin response due to contact with environmental materials manifested as acute or chronic eczema. Patch test is the standard test to recognize responsible allergen. The objective of this study was to evaluate the frequency of false positive patch test responses in patients with Exited Skin Syndrome (ESS).Materials...
[ 7 ] - Laser-assisted hair removal: comparison of long-pulsed alexandrite and long-pulsed Nd:YAG lasers, individually and in combination
Background and aim: Laser is one of the most recent techniques which has widespread use in the treatment of many skin diseases. This technique has been successfully used to remove unwanted hairs in hirsutism. The aim of this study was to evaluate and compare the efficacy and safety of long-pulsed 755 nm alexandrite and long-pulsed 1064 nm Nd: YAG lasers individually and in combination for perma...
