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. The volume and surface of nasolabial folds were analyzed using CSI computer software and high frequency ultrasonography of these folds before, and 2, 12, and 24 weeks after the injection. The obtained data were analyzed using SPSS software version 20. P≤0.05 was considered significant. Results: Evaluation of the nasolabial folds before and after treatment showed significant reduction in volume of wrinkles 24 weeks after injection in both the HA gel A (-29.93±32%, P=0.022) and gel B (-23.60±26%, P=0.019). The surfaces of the wrinkles significantly decreased 24 weeks after injection of HA gel A (-29.90±31%, P=0.012) and gel B (-21.96±26%, P=0.026). Conclusion: These HA fillers provided a significant, long-lasting correction of moderate nasolabial folds. Overall, we observed no statistically significant differences in any of the measurements between the 2 gels. However, there were more observed changes made by gel A compared to gel B.

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.

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 and methods: Fourteen patients older than 12 years with allergic contact dermatitis who had more than one positive reaction in first patch test were re-tested with the same allergens at the time of remission of their eczema. The patches were removed after 48 hours and responses read according to ICDRG guidelines.Results: The patients included 5 men and 9 women with a mean age of 34.92 years. The most common allergens in first patch test were: nickel sulfate (10), cobalt chloride (5), colophony (4), potassium dichromate, PTBF, fragrance mix and MCI/MI (3 each). In the repeated test, the most common positive responses were: nickel (10), cobalt and colophony (4 each), potassium dichromate and fragrance mix (3 each). In 6 of 14 patients the results of second test was different from first one. Three of these patients had active eczema at the time of first test, which in 2 of them one positive response and in one of them, 2 positive responses became negative in second test.Conclusion: It is recommended that patch test be repeated after a while in patients with multiple positive reactions in first test, particularly after remission of active eczema.

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 permanent hair removal. Materials and Methods: This single-blind randomized clinical trial was conducted on 25 patients. They were treated by alexandrite or Nd: YAG or combination of them in 4 sessions with 8 weeks intervals. The treatment was applied on their medial and lateral sides of both legs. All the parameters of the systems were set on the company defaults. Subjects were evaluated 1 and 8 months after completion of the treatment. Hair count was measured by Visiomed device and digital camera photographs every session. To calculate mean hair reduction, the difference between hair count before and after treatment was divided by hair count before treatment. Pain severity, measured by Visual Analogue Scale (VAS), and side effects (bullae, scar and pigmentation changes) were recorded every session. The data were analyzed with ANOVA, post hoc Tukey and chi square tests. Results: Fifteen patients completed the study and 10 patients were excluded due to appearance of bullae in 2 patients and refuse to continue in 8 patients. The mean hair reduction measured by Visiomed 8 months after last treatment was: 61.96 ±21.09, 60.03±23.40 and 68.05±21.23 percent for alexandrite, Nd: YAG and combination therapy, respectively. When digital camera photos were used for measurement of hair reduction these values were 85.99±11.62, 73.60±16.57 and 79.61±18.08 percent, respectively. The differences between the systems were not significant (ANOVA, P>0.05). In paired comparison of the systems, no significant differences were observed either (Tukey test). The incidence of adverse effects (hyperpigmentation) and pain severity were significantly greater in area received combination therapy (P=0.001).Conclusion: Both alexandrite and Nd:YAG laser systems were effective in hair removal. In contrast, combination therapy did not have more efficacy and also caused more side effects.
