Introduction: Narrowband ultraviolet B (NBUVB) phototherapy is a well-established treatment option for a variety of dermato- logic conditions. The initial dosage is obtained either by determining the patients’ minimal erythema dose (MED) or their Fitzpat- rick skin phototype (SPT). MED determination is a better way to establish the proper initial dose as it is more objective. However, in practice, SPT is more commonly used as it is more convenient, and MED data in Filipinos are scarce. Objectives: To establish data determining the MED values of Filipino adults that can serve as a basis to standardize the initial dose of NBUVB phototherapy in a tertiary hospital. Methods: We enrolled 86 volunteers in a cross-sectional analytical study to determine their MED and assess if there is any asso- ciation between their MED and the participants’ age, sex, skin prototype, ancestry, and daily duration of sun exposure. Results: The median MED of the participants is 800 mJ/cm2 (IQR 600-800 mJ/cm2 ). A majority of 38 participants (44.19%) have a MED of 800mJ/cm2 followed by 600mJ/cm2 for 23 (26.74%) participants. There was also a significant association between study partici- pants’ MED with respect to their Fitzpatrick skin type (p=<0.001) and ancestry (p=0.03), but with no association with regards to age (p=0.291), sex (p=0.245), and daily duration of sun exposure (p=0.237). Conclusion Majority of the participants have a median MED value of 800 mJ/cm2. Based on this MED value, the initial dosage of NBUVB at 50-70% of the MED would translate to an initial dose of 400-560 mJ/cm2.

Progressive macular hypomelanosis is an idiopathic acquired hypopigmentary disorder first described in 1988. The disorder is characterized by ill-defined, non-scaly, round to oval, hypopigmented patches symmetrically localized on the trunk. No clinical symptoms have been observed. Currently, diagnosis is made on clinical grounds and any histological, laboratory investigations are not diagnostic. This disorder does not respond to conventional treatment and its clinical course is variable. We experienced a case of progressive macular hypomelanosis that was successfully treated with narrow band UVB phototherapy.

BACKGROUND: Narrow-band UVB phototherapy using 311+-2nm wavelength is in widespread use due to its greater efficacy and, possibly, safety compared with broad-band UVB sources. OBJECTIVE: We performed emollient narrow-band UVB(NBUVB) phototherapy to evaluate the clinical efficacy and safety in Korean psoriasis patients. METHODS: Fifteen psoriasis patients received narrow-band UVB phototherapy. We categorized each patient into clearing, improvement, or failure groups based on the therapeutic efficacy, and measured the PASI score every two weeks. RESULTS: 1. Among patients who received narrow-band UVB phototherapy, clearing was shown in 40.0% and improvement in 27.7%, and failure in 33.3%. 2. The total number, duration, final and cumulative doses to achieve grade IV were 16.3, 39 days, 1,050mJ/cm2 and 12,125mJ/cm2 respectively. 3. There were some side effects of NBUVB phototherapy such as pruritus(53.3%) and mild burning(13.3%). CONCLUSION: Narrow-band UVB phototherapy is a effective treatment modality which is convenient and less erythemogenic in psoriasis. It will be used more and more and play an important role in the treatment of psoriasis.
