BACKGROUND/AIM Narrowband UVB (Nb UVB) treatment is commonly used for the management of psoriasis and atopic dermatitis, and is less often used for vitiligo in children. The aim of this study was to evaluate the efficacy and short-term safety of Nb UVB phototherapy in children diagnosed with vitiligo retrospectively. MATERIALS AND METHODS A total of 26 patients younger than 18 years with the ...

Melanocytes are found scattered throughout the basal layer of the epidermis. Following hormone or ultraviolet (UV) light stimulation, the melanin pigments contained in melanocytes are transferred through the dendrites to the surrounding keratinocytes to protect against UV light damage or carcinogenesis. This has been considered as a morphological indicator of melanocytes and melanoma cells. Sma...

BACKGROUND Progressive macular hypomelanosis is characterized by ill-defined, non-scaly, hypopigmented macules primarily on the trunk of the body. Although numerous cases of progressive macular hypomelanosis have been reported, there have been no clinicopathologic studies of progressive macular hypomelanosis in Korean patients. OBJECTIVE In this study we examined the clinical characteristics,...

BACKGROUND Phototherapy is an effective treatment for several photoresponsive diseases. Many patients are unable to attend hospital-based treatment and prefer home phototherapy. OBJECTIVES The purpose of this study is to survey patients who were prescribed home phototherapy to determine the viability of narrow-band ultraviolet B home units in the continuous or maintenance treatment of photore...

Abstract Background Psoriasis is a chronic and non-transient disease with increased epidermal proliferation in the skin. Dysregulation of immune system an important factor this pathology. Inflammation markers, pro-inflammatory cytokines, cells are reported to be changed psoriasis. Study design In current cohort study, possible changes interleukin-6 (IL-6), neopterin levels, kynurenine (Kyn) pat...

This paper proposes an effective anomaly detection algorithm for a forward-looking ground-penetrating radar (FLGPR). One challenge for threat detection using FLGPR is its high dynamic range in response to different kinds of targets and clutter objects. The application of a fixed threshold for detection in a full-band radar image often yields a large number of false alarms. We propose a method t...
