Abstract

Background: Melasma is a hyperpigmentation disorder that affects the quality of life, especially in women. Hydroquinone has remained the mainstay of melasma treatment. However, its safety for long-term usage became a great concern. Combination therapy, such as niacinamide and kojic acid, can be used as an alternative melasma treatment due to different mechanisms of action and synergism. Purpose: The aim of this study was to compare the efficacy and safety of a combination of 4% niacinamide and 4% kojic acid (N-K) vs. 4% hydroquinone (HQ) in epidermal melasma. Methods: This was a randomized, double blind, clinical study on 13 female epidermal melasma patients at the Cosmetic Dermatology Outpatient Clinic of Dr. Hasan Sadikin Hospital, Bandung. Patients received two creams, a combination of N-K and HQ, for split-face therapy, regardless of the sides of the face. All patients were followed up at 4 and 8 weeks. The clinical efficacy was assessed for skin lightening effects using a spectrophotometer (L* value) and the melasma area severity index (MASI). Adverse effects were assessed in all patients. Result: Both the N-K and HQ groups showed significant improvement in skin lightening and MASI scores on week 8 (p <0.05). There was no statistically significant difference in efficacy between the N-K and HQ groups (p >0.05). None of the patients in the N-K group complained of any adverse effects. Whereas in the HQ group, 23.07% presented with pruritus and mild erythema.

Abstract

Objective: To determine the prevalence of chlamydial infection in male urethra and female cervix of HIV-positive patients based on PCR assay in Teratai Clinic, Dr. Hasan Sadikin General Hospital Bandung. Methods: A cross sectional observational study with consecutive sampling method, which was conducted in Teratai Clinic during the month of July 2012. All participants underwent history taking, physical examination, and PCR assay for C. trachomatis. Swab samples were obtained from male urethra and female endocervix. Results: Eighty one HIV-positive patients, consisted of 48 males and 33 females were included in this study. The PCR examination for C. trachomatis was positive in 14 of 81 subjects (17.3%), with 10 (20.8%) urethral chlamydial infection in 48 males and four (12.1%) cervical chlamydial infection in 33 females. Conclusions: The study concluded that the prevalence of chlamydial infection in male urethra and female cervix of HIV-positive patients were 20.8% and 12.1%, respectively. Identifying chlamydial infection based on PCR testing should be considered for routine screening test in HIV-positive patients.    Keywords: Chlamydia trachomatis, HIV, prevalence, PCR DOI: 10.15850/ijihs.v1n1.107
