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.

BACKGOUND: Narrow-band ultraviolet B (NBUVB) phototherapy has appeared to be effective in clearing psoriatic lesions. Calcipotriol has been combined with a number of the systemic antipsoriatic treatments, improving efficacy or reducing the systemic treatment required. OBJECTIVE: We performed calcipotriol-NBUVB combination therapy to evaluate the clinical efficacy and the safety in Korean psoriasis patients. METHOD: In the psoriasis clinic at Seoul National University Hospital, 69 psoriasis patients were treated with calcipotriol-NBUVB. Phototherapy was given once daily, three times a week, and the dose was gradually increased. Calcipotriol ointment was applied twice a day. The PASI score was used to evaluate the effects of the treatment and the patients were classified according to clearance, improvement, or failure. RESULTS: The therapeutic results showed 53.6% for clearance, 31.9% for improvement and 14.5% for failure. The total number, duration, final and cumulative doses to achieve grade IV were 16.1, 41.8days, 1487.3mJ/cm2, and 15234.5mJ/cm(2) respectively. Of 69 patients, 44 patients experienced variable adverse effects, but there was no significant adverse effect to discontinue the therapy. CONCLUSION: Our results demonstrated that using calcipotriol ointment with NBUVB phototherapy is an effective therapeutic method for psoriatic patients.

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. However, its optimal dose increment regimen is not determined. OBJECTIVE: We performed narrow-band UVB(NBUVB) phototherapy to compare clinical efficacy between fixed and 20% incremental regimen in Korean psoriasis patients. METHODS: Twenty four psoriasis patients received narrow-band UVB phototherapy. Among them, fifteen patients received fixed regimen and nine patients, 20% incremental regimen. We categorized each patient into clearing, improvement, or failure groups based on the therapeutic efficacy, measured the PASI score every two weeks and calculated cumulative dose of narrow-band UVB. RESULTS: We found no statistically significant difference between two regimen. However, there is a tendency that irradiation number and duration of treatment are smaller in 20% incremental regimen but, in terms of cumulative dose, fixed incremental regimen is better than 20%. CONCLUSION: These results suggests that 20% incremental regimen may clear psoriasis faster than fixed but that the latter regimen may be equally effective as it requires slighty more treatment sessions at a lower cumulative dose.
