ABSTRACT
BACKGROUND: Hirsutism is estimated to affect 10% to 20% of females, provoking significant psychological damage and social embarrassment. Polycystic ovary syndrome is a major cause of hirsutism. AIM: Assessing the impact of adding combined oral contraceptives (COCs) or metformin to laser hair removal on the quality of life of polycystic ovarian syndrome (PCOS) patients with hirsutism. METHODOLOGY: One-hundred-fifty PCO patients diagnosed with hirsutism were included in this study. Patients were randomized into three groups: group 1 received laser hair removal alone, group 2 received metformin and laser hair removal, and group 3 received COCs and laser hair removal. A diode laser with a wavelength of 810 nm was used for hair removal in all patients according to a protocol of 6 monthly sessions followed by another two sessions after three and six months. Patients were assessed using a visual analog scale (VAS) and Dermatology Life Quality Index (DLQI) and a customized questionnaire (Hirsutism Life Quality Index; HLQI). RESULTS: All patients showed a significant improvement in both quality indices (DLQI and HLQI) after treatment relative to pretreatment. Group 3 showed significantly better improvements when compared with group 2 and group 1. At three and six months, group 3 showed non-significantly better DLQI and HLQI as compared with at zero months. On the other hand, group 2 patients displayed significant worsening of both DLQI and HLQI scores at three months, with subsequent improvements again at six. Finally, group 1 patients showed nonsignificant worsening at three months, and significant worsening at 6 months. CONCLUSION: Combining hormonal treatment with laser hair removal can achieve greater hair reduction, significant improvements in patients' QOL, and better maintenance as compared with when combining metformin with laser hair removal or conducting alone.

BACKGROUND: Chemical peelings are used on a wide scale in cosmetic field including melasma treatment. They often provide clinicians with flexibility in tailoring treatments according to patient needs and satisfaction. OBJECTIVE: To evaluate safety and efficacy of chemical peeling as single agents in melasma management in patients with darker skin types. METHODS: We included randomized controlled trials (RCTs) and prospective studies that assessed efficacy and safety of chemical peeling as single agents for facial melasma. An online bibliographic search was conducted, and data were extracted from the included studies. RESULTS: Ten RCTs and three prospective comparative studies (No. of patients = 478) were included. The overall effect estimate favored Glycolic acid (GA) over trichloroacetic acid peel in terms of melasma activity and severity index (MASI) (mean difference [MD] -1.89, 95% CI [-3.26, -0.52], P = .007). On the other hand, the overall effect estimates did not favor GA over tretinoin (MD 0.53, 95% CI [-0.46, 1.52], P = .3), vitamin C iontophoresis (MD 1.50, 95% CI [-0.50, 3.50], P = .14), and amino fruit acid (MD 0.39, 95% CI [-0.64, 1.42], P = .46) in terms of MASI. The overall effect estimates favored trichloroacetic acid peel (MD -5.30, 95% CI [-6.41, -4.19], P < .001) and Jessner's solution (MD -3.20, 95% CI [-5.35, -1.05], P = .004) over topical hydroquinone in terms of MASI. CONCLUSION: In conclusion, chemical peelings are effective as single agents for management of melasma in patients with darker skin types, with the use of topicals as maintenance treatment.

BACKGROUND: Pityriasis rosea (PR) is a common papulosquamous skin disease in which an infective agent may be implicated. Toll-like receptors (TLRs) play an important role in immune responses and in the pathophysiology of inflammatory skin diseases. Our aim was to determine the possible roles of TLRs 3, 7, 8, and 9 in the pathogenesis of PR. METHODS: Twenty-four PR patients and 24 healthy individuals (as controls) were included in this case control study. All recruits were subjected to routine laboratory investigations. Biopsies were obtained from one active PR lesion and from healthy skin of controls for the detection of TLR 3, 7, 8, and 9 gene expression using real-time polymerase chain reaction. RESULTS: This study included 24 patients (8 females and 16 males) with active PR lesions, with a mean age of 28.62 years. Twenty four healthy age- and sex-matched individuals were included as controls (8 females and 16 males, with a mean age of 30.83 years). The results of the routine laboratory tests revealed no significant differences between both groups. Significantly elevated expression of all studied TLRs were detected in PR patients relative to healthy controls (p < .001). CONCLUSIONS: TLRs 3, 7, 8, and 9 might be involved in the pathogenesis of PR.
ABSTRACT
Human herpesvirus (HHV) 6 and 7 are involved in the pathogenesis of pityriasis rosea (PR). Our aim was to evaluate the role of the innate immune response in PR through the detection of Toll-like receptors (TLR) 2, 3, 4, 7, 8, and 9 expression in the skin of affected patients and to detect the possibility of being induced by HHV-6 and/or HHV-7 viral coexistence in these patients. Twenty-four patients with PR and 24 healthy controls were included in this case-control study. Biopsy was obtained from the PR lesion and from the healthy skin of controls for detection of HHV-6 and 7 as well as TLRs 2, 3, 4, 7, 8, and 9 gene expression using real-time polymerase chain reaction (PCR). Significantly elevated expression of all studied TLRs and significantly higher viral load of HHV-6 and 7 in PR cases were detected. A significant higher expression of TLR2 and 4 in HHV-7 positive cases and a significant positive correlation between TLR9 and HHV-7 viral load were documented. HHV6 and 7 may also be involved in the pathogenesis of PR via TLR pathways.
