Background: Acne vulgaris (AV) is the commonest skin disorder, whereas soybean isoflavone had been proved as antiandrogen that is it can inhibit the enzyme 3ß-hydroxysteroid dehydrogenase,17ß-hydroxysteroid dehydrogenase and 5α-reductase. The purpose of this study is to prove the advantage of soybean isoflavone as antiandrogen on AV. Methods: this study is a clinical study using randomized pretest-posttest control group design. This study is a study with 40 samples randomized into 2 groups, i.e. placebo group and 160 mgs of isoflavone group, the duration is 12 weeks, conducted a double-blind manner. The dependent variabel is total of AV lesion, whereas the intermediate variable is DHT that will be examined using ELISA. Defferential test and multivariate analysis were performed on dependent, independent and intermediate variables. Results: This study found that the difference in mean of total AV lesion before treatment was not significant (p: 0.099), whereas after treatment it differed significantly (p: 0.000), with significant delta difference (p: 0.000). Difference of mean DHT level before treatment was not significant (p: 0.574), whereas after treatment it differed significantly (p: 0.000), with significant delta difference (p: 0.000). Delta of DHT (p: 0.003) (r: 0.736) had significant influence on delta of total AV lesion (P < 0.05). Conclusion: This study concludes that supplementation with 160 mgs/day of soybean isoflavone can reduce total AV lesion as a result of decreased DHT level.

BACKGROUND: Acne vulgaris (AV) is a chronic inflammatory disease in the pilosebaceous unit. Recent research has begun to focus on the essential relationship between oxidative stress and the pathogenesis of AV. The use of antioxidants like coenzyme Q10 (CoQ10) that has various advantages as adjuvant therapy is expected to be beneficial for AV. AIM: The study was aimed to analyze the effect of CoQ10 supplementation on serum SOD levels and the severity of AV patients. METHODS: A double blind-randomized controlled trial was carried out on 36 patients with AV and classified according to severity degree of AV. These patients were randomly divided into two groups (treatment group with tretinoin 0.025% cream and once-daily supplementation of CoQ10 100 mg tablet; and placebo group with tretinoin 0.025% cream and once-daily placebo tablet). Response to treatment was based on serum superoxide dismutase (SOD) level and AV severity degree. RESULTS: Administration of CoQ10 to AV patients significantly increase serum SOD level (p = 0.008) and improves the severity of AV after 8 weeks (p = 0.008). CONCLUSION: CoQ10 supplementation can increase serum SOD levels and improve the severity of AV.

Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS) are serious diseases in the world in which one of transmission methods is through sexual intercourse. This study aimed to explain the influential host factors to the incidence of HIV/AIDS in key populations. The study was conducted on March-September 2016. The study was observational analytic with case-control design in key populations in Pati District. Cases were 53 patients living with HIV/AIDS, while controls were 53 patients not living with HIV/AIDS. The sampling technique employed was consecutive sampling. Data were obtained from medical records and interview questionaire. This study applied chi-square test to analyze bivariate data, and multiple logistic regression to analyze multivariate data. Results indicated that the influential factors to the incidence of HIV/AIDS in key populations were inconsistent condom use behavior, records of suffering from sexually-transmitted infections (STIs), and forms of sexual activity. While, factors which did not influence the incidence of HIV/AIDS were multiple sex partners behavior, sex accessories use behavior, tattoo needle use behavior, injecting drug use behavior. In conclusion, several influential factors to the incidence of HIV/AIDS in key populations are the inconsistent condom use behavior, records of suffering from STIs, and forms of sexual activity.

Background: Acne vulgaris (AV) is an inflammatory condition of pilosebaceous follicles that is commonly experienced in adolescents and young adults. The pathogenesis of AV is multifactorial, such as caused by inflammation and external factors of acne exposome, which have an impact on the pathogenesis of acne in the use of masks.Objective: To determine the effect of using a mask and the number of acne vulgaris on students of the Faculty of Medicine, Diponegoro University.Methods: This research is an observational type with a cross sectional design. The research subjects were 58 students of the Faculty of Medicine, Diponegoro University with an age range of 19-23 years who used masks. The data obtained are primary data from the questionnaire. The analytical test used is bivariate chi square analysis.Results: This study showed that there was no significant effect between the type of mask and the incidence of acne vulgaris p 0.610 (p>0.05), the duration of the use of masks and the incidence of acne vulgaris p 0.200 (p>0.05), and the frequency of using masks with the incidence of acne vulgaris p 0.689. (p>0.05)Conclusion: There is no effect between the use of masks and the incidence of acne vulgaris.
