4.Prevalence, epidemiology, and clinical characteristics of Melasma in Philippine dermatology patients: A multicenter, cross sectional study
Journal of the Philippine Dermatological Society 2019;28(1):15-23
Background:
Melasma is an acquired hyperpigmentary disorder occurring on sun-exposed areas of the face and
neck. There is little information on its prevalence, epidemiology and clinical characteristics in the Philippines.
Objective:
To determine the prevalence, epidemiology and clinical characteristics of melasma in Philippine
dermatology patients.
Methods:
This was a multicenter, cross-sectional study conducted from July to December 2013. The investigators
determined the prevalence of melasma in 12,068 dermatology patients from six government hospitals and private
clinics in Metro Manila, Philippines. The melasma patients, aged 18 years and above, were given self-administered
questionnaires with topics related to demographic information and medical history. They were also examined by
the investigators (dermatologists) to determine the clinical profile of their melasma.
Results:
Of the 12,068 dermatology patients who were seen at the selected hospitals and private clinics, 153 (1.26%)
were clinically diagnosed with melasma. A majority of the melasma patients were Filipinos (73.20%), aged 41-50
years old (37.91%), with an average age of 42.40 + 9.68 years, and Fitzpatrick skin types III and IV (29.41% and
57.52%, respectively). Melasma was more prevalent in females (81.70%), most of whom had prior history of
pregnancy (76.8%). Oral contraceptive use was also reported in 37.6% of the female patients from which 63.83%
have used it for only 1 year or less. A majority had no coexisting thyroid disease (75.16%) and daily sun exposure
was limited to 1 hour or less for most patients (43.14%). Their melasma was mostly malar in distribution (60.13%),
epidermal (61.44%), and mild (51.63%) to moderate (27.45%) in severity. The average mMASI score was 4.63 + 3.32.
Conclusion
The prevalence of melasma was low among Philippine dermatology patients sampled. A majority of the
melasma patients were Filipinos, aged 41-50 years old, with Fitzpatrick skin type IV, limited sun exposure, and no
coexisting thyroid disease. They were mostly females with a prior history of pregnancy. Their melasma was mostly
malar in location, epiderma type, and mild in severity. These descriptive data can serve as baseline information for
further studies on melasma in the Philippines.

BACKGROUND: Melasma, a common chronic pigmentary disorder, is resistant to various treatments. Recently, pulse-in-pulse type of intense pulsed light (PIP IPL) has been introduced as a treatment for melasma. It can emit multiple peaks during one pulse wave to deliver photothermal energy more effectively with gentle and even low energy so that complications are minimal. OBJECTIVE: The purpose of this study was to compare the efficacy and safety of PIP IPL to low-fluence, multi-pass, Q-switched Nd:YAG laser in the treatment of facial melasma. METHODS: Fifteen female patients with melasma who had Fitzpatrick skin type III or IV were enrolled in this study between November 2014 and April 2015. Patients underwent 6 sessions of treatment at an interval of 1 week. One half of each patient's face was treated with 2 passes of PIP IPL with a fluence of 13~15 J/cm₂. The other half of the face was treated with 4 passes of Q-Switched Nd:YAG laser with a fluence of 1.6~1.8 J/cm₂. Results were evaluated at every visit, including modified Melasma Area and Severity Index (MASI) score, subject's global assessment, and investigator's global assessment. RESULTS: Modified MASI scores were significantly (p<0.05) reduced in both groups after 6 treatment sessions. Q-Switched Nd:YAG laser treatment was more effective than PIP IPL for the treatment of melasma, although the two treatments did not significantly (p=0.44) differ in effectiveness. However, the discomfort levels of patients in the PIP IPL group following procedures were significantly lower compared to those in the Q-Switched Nd:YAG group. CONCLUSION: The current investigation demonstrated that PIP IPL treatment for melasma in Korean women was not inferior to collimated low fluence Q-switched Nd:YAG laser treatment.

10.Acral Lentiginous Melanoma Developing during Long-standing Atypical Melanosis: Usefulness of Dermoscopy for Detection of Early Acral Melanoma.

Clinical guidelines suggest that suspicious pigmented lesions of the plantar or palmar area require biopsy for early detection of acral melanoma. We present here a case of acral lentiginous melanoma in which various melanocytic atypia was observed at each biopsy site, including focal melanocytic proliferation. We suggest that this atypical melanosis is part of a contiguous phase of invasive tumor growth, which is known as the very early stage of melanoma in situ. In addition, noninvasive dermoscopy has been effective for the early discovery of hidden lesions of acral melanoma.
