Introduction: Seborrheic dermatitis (SD) is a chronic-recidive inflammatory skin disorder with predilection in areas rich of sebaceous gland. The most common clinical manifestations are pruritus and scales. Although SD can be diagnosed without special tools, other examinations may be needed to determine additional specific therapy. Trichoscopy is one of the noninvasive tools which can help to diagnose SD as it can provide the microstructure view of the scalp. Materials and Methods: This descriptive study was conducted to explore the trichoscopic features of SD and its characteristics. There were 96 SD patients enrolled in this study. The scalp was divided into four areas, and each area was scored based on Seborrheic Area Severity Index, comprising erythema, desquamation, number of papules, and percentage of lesion area. The most severe area was examined with a trichoscopy to observe the characteristics of hair and scalp. The association between trichoscopic findings and SD severity was analyzed with Fisher's exact test. Results: Overall, the participants were 36% males and 64% females with the mean age of 30 (13–70) years old. Based on the trichoscopic examination, the most common findings were thick hair shafts (72%), white scales (69%), arborizing thin vessels (38%), yellowish area (36%), and structureless red area (19%). These findings were not significantly different between mild and moderate SD ( P > 0.05). Conclusion: Considering the merits and demerits of trichoscopic examination, it can be helpful to aid the diagnosis of SD. Further studies in Asian population with greater sample size are needed to demonstrate more significant result.

Background: Dermatotherapy is an important topic in Dermatology and Venereology module. The time allocated for dermatotherapy topic is limited, so that the development of learning method is needed to achieve the learning objectives. Blended learning is a combination of e-learning and face to face lecture session. This method is often used when there is less time available for lecturing and limited number of teachers. This learning method is expected to be more effective and efficient for the students and also the teachers. This study was conducted to examine the effectiveness of blended learning method used in dermatotherapy topic, and to identify the obstacle of using this method. Methods: This study is a cross sectional study, using quantitative and qualitative approach, involving 22 fifth-year medical students of Faculty of Medicine Universitas Indonesia who enrolled in dermatology and venereology module. We collected data from questionnaire, pre and post-test, and feedback from the students. Comparison of pre-test and post-test results were analysed using paired T test, and followed by bivariate test of students’ characteristic, gadget usage and e-learning activities associated with the increased post-test score.Results: An increased in post-test score was found to be statistically significant (p<0.05). Approximately 95,4% of students passed the final exam on the dermatotherapy subject. Bivariate analysis revealed that the number of gadgets owned, digital usage and e- learning activities did not have a significant effect on the post-test score. Based on the students’ feedback, blended learning had a positive impact on helping their learning process; however, the materials of e-learning must be interactive, informative and comprehensive. Face-to-face lecture is still an important component in learning hence it is irreplaceable. Conclusion: Blended learning is an effective method of learning and should be considered if there is limitation of lecture time and number of teachers available. By using this method, medical students are more flexible in their study and it can be adjusted to their own learning style hence heling them understand better. Further development and improvement are needed for this method as to achieve the learning objectives.  Keywords: blended learning, dermatotherapy, medical students

Background: Curcuma xanthorrhiza Roxb. exerts its anti-inflammatory effects by reducing the concentration of IL-6, IL-8, and phosphorylase kinase, which has role in keratinocyte proliferation. Our study aimed to evaluate the efficacy of C. xanthorrhiza in psoriasis.Methods: From 18 to 59 year-old patients with mild psoriasis, 2 similar lesions were selected. The severity assessment was based on the psoriasis area severity index (PASI), Trozak score, and K6 expression. Using a double-blinded randomized method, lesion was treated with 1% C. xanthorrhiza ointment vs placebo for 4 weeks. The results were analyzed by the chi-square test using STATATM V.12 software (Stata Corp.).Results: The study was conducted in 2010 to 2012 with 17 subjects participated. The median of PASI score were reduced significantly in both lesions, either treated with 1% C. xanthorrhiza ointment vs placebo; however when compared between the group, it was not significant (p=0.520). The Trozak score were reduced in lesions treated with 1% C. xanthorrhiza ointment; but it was not significant (p = 0.306). In lesions treated with placebo, the Trozak score was increased significantly. The difference of Trozak score between lesions treated with C. xanthorrhiza and placebo was significant (p=0.024). There was no significant difference of K6 expression in lesions treated with 1% C. xanthorrhiza ointments or placebo as well as on the difference of mean values of K6 expression between the group (p=0.827).Conclusion: Based on the results, 1% C. xanthorrhiza ointment is effective treatment option for mild psoriasis, but longer follow-up period is suggested to confirm this results. C. xanthorrhiza ointment is safe for topical administration as there were no side effects reported in this study.

Nail involvement in Langerhans cell histiocytosis (LCH) is very uncommon. We describe a 9‐month‐old boy with longitudinal purpuric bands, onychodystrophy, and paronychias on his fingernails and toenails, which antedated manifestations of recurrent bilateral spontaneous pneumothorax and elevated transaminases. The diagnosis of nail LCH was then confirmed by immunohistochemistry demonstrating positive S100 and CD1a staining in the epithelium of nail bed tissue. This case report affirms that nail involvement may be the initial manifestation of multisystem LCH and could portend an unfavorable prognosis.

The aim of the study is to evaluate the effectiveness of water as a substitute for sodium bicarbonate plus solution in the neutralisation process of chemical peeling using a 35% glycolic acid solution. This randomised, double-blind, split-face, controlled trial was conducted in an outpatient setting. A total of 126 healthy patients with skin phototypes IV-V aged between 18 and 60 years old were recruited. Chemical peeling was performed with 35% glycolic acid solution. One side of the face was neutralised with water, and the other side of the face was neutralised with a sodium bicarbonate plus solution. The main outcome of this study was measured by the degree of erythema, pruritus and pain scores. Significant difference in the pain score immediately after the neutralisation process of the chemical peeling with glycolic acid was seen. However, there were no significant differences in the degree of erythema or the pruritus score. These results indicate that water can be used as a substitute for sodium bicarbonate plus solution in the neutralisation process of chemical peeling with 35% glycolic acid in patients with skin phototypes IV-V.
