ABSTRACT
Combined oral contraception was used in many studies for treatment of acne and hirsutism. However, levonorgestrel (LNG) alone has not been evaluated before. Our objective is to evaluate the efficacy of oral contraceptive (OC) pills containing LNG and ethinyl estradiol (EE) compared with LNG only for the treatment of acne and hirsutism in a randomized, controlled prospective clinical trial. Eighty females (20 with acne, 20 with hirsutism, and 40 healthy females) received LNG + EE or LNG only for 6 months. Assessment of acne by global acne grading system (GAGS) and hirsutism by modified Ferriman-Gallwey scale (MFGS) grading system and serum free testosterone was measured before and 6 months after treatment. Serum free testosterone was significantly higher before treatment in acne and hirsutism patients compared to control group (P < .000). In acne patients, after 6 months of treatment with LNG/EE, serum free testosterone, and (GAGS), were significantly decreased compared to LNG only (P < .000). In hirsutism group, after 6 months of treatment with LNG/EE, serum free testosterone and (MFGS), were nonsignificantly decreased compared to LNG only. OCs containing either LNG/EE or LNG seem to be effective and safe treatment for acne and hirsutism.

BACKGROUND: The new modified Melasma Area and Severity Index (mMASI) score, the recently used outcome measure for melasma, has not been tested to determine its sensitivity to change in melasma. OBJECTIVE: To determine the reliability, validity, and sensitivity to change overtime of the mMASI score in assessment of the severity of melasma. METHODS: Pearson correlation, Cronbach alpha, and intraclass correlation coefficient were calculated to assess the reliability of the mMASI score. Validity of the mMASI scale was carried out using Spearman correlation between mMASI total score (before and after treatment), clinical data, and patient's responses. RESULTS: The mMASI score showed excellent reliability and good validity for assessment of the severity of melasma. The authors also determined that the mMASI score demonstrated sensitivity to change over time. CONCLUSION: An excellent degree of agreement between the mMSAI and MASI scores was revealed. The mMASI score is reliable, valid, and responsive to change in the assessment of severity of melasma. Moreover, the mMASI score was found to be easier to learn and perform and simpler in calculation compared with the MASI score. Overall, the mMASI score can effectively replace the MASI score.

BACKGROUND: Melasma is a common disorder of facial hyperpigmentation that is often resistant to treatment. OBJECTIVE: To evaluate the efficacy of trichloroacetic acid (TCA) peeling in comparison with double frequency Q-switched neodymium-doped:yttrium aluminum garnet (QS-Nd:YAG) laser in the treatment of melasma. PATIENTS AND METHODS: Sixty-five adult Egyptian female patients with melasma were enrolled in this study. Wood light was used for determination of the histological type of melasma. The patients were divided into 4 groups according to treatment modalities: peeling with different concentrations of TCA and double frequency QS-Nd:YAG laser. Trichloroacetic acid peeling was performed every 2 weeks up to 8 sessions, whereas laser treatment was performed every month up to 6 sessions. Melasma area and severity index (MASI) score was used before and after treatment for evaluation. RESULTS: Improvement percentage of MASI score was significantly higher among patients treated with TCA 25% (p < .001). Epidermal type of melasma was significantly improved compared with the dermal type (p = .0029). Q-switched neodymium-doped:yttrium aluminum garnet laser showed the highest incidence of postinflammatory hyperpigmentation (53.3%). CONCLUSION: Trichloroacetic acid peeling is effective in the treatment of melasma, TCA 25% was the most effective concentration. Q-switched neodymium-doped:yttrium aluminum garnet laser is not recommended in the treatment of melasma because it was associated with the highest incidence of complications.
