The Effectiveness of Light Emitting Diodes with 592 nm Yellow Light for Korean Photoaged Skin / 대한피부과학회지

BACKGROUND: As aging occurs, the skin develops more wrinkles and pigmentation, becomes drier, and loses its elasticity. In previous reports, light-emitting diode (LED) phototherapy was proven to stimulate collagen synthesis and accelerate fibroblast-myofibroblast transformation, which has a composite rejuvenation effect. OBJECTIVE: To evaluate the effectiveness and safety of LED phototherapy with 592 nm yellow light for photoaged skin. METHODS: Forty patients with photoaged skin (Korean photographic scale; grade 4approximately7) were enrolled and treated with an LED device producing 592+/-10 nm yellow light for 5 minutes twice a week for 4 weeks. The skin changes were assessed at 0, 2, 4, and 8 weeks by clinical photographs and the Cutometer(R) & Mexameter(R) (MPA 580, Courage+Khazaka Electronic GmbH, Koln, Germany). Measurements were made on the cheek, periorbital area, nasolabial fold, and glabella. RESULTS: At the final visit at 8 weeks, the Cutometer(R) parameters R4 and R6 decreased significantly compared to before treatment, from 0.118 to 0.099 for the periorbital (p=0.017) and 0.517 to 0.425 for the nasolabial fold (p=0.003). The average melanin index decreased significantly, from 133.65 to 124.55 (p<0.005). Fine improvement of wrinkles was shown grossly by reviewing follow-up clinical photographs. No adverse reactions occurred. LED phototherapy with 592+/-10 nm wavelength can be effective and safe in the treatment of photoaged skin. CONCLUSION: The findings suggest the LED with 592 nm yellow light might be an adjuvant therapeutic tool for photoaged skin.

Clinical Trial to Evaluate the Efficacy and Safety of a Home-use Intense Pulsed Light Device for Hair Removal, Treatment of Acne and Pigmentation Disorders, and Fine Wrinkle Reduction / 대한피부과학회지

BACKGROUND: Home-use devices designed for cosmetic purposes have recently gained popularity. Small, low-energy, low-cost intense pulsed light (IPL) systems provide safe, convenient, and private treatment for several medical conditions. OBJECTIVE: In this study, we aimed to assess the efficacy and safety of a home-use IPL device for hair removal, acne treatment, achieving a whitening effect for hyperpigmentation, and wrinkle reduction. METHODS: Five IPL hair removal treatment sessions were performed at 1-week intervals. A total of 10 sessions were performed in a split-face manner for other medical conditions. Four independent randomized controlled trials were performed using a blind evaluation method. All subjects were followed up twice to evaluate the maintenance of efficacy. RESULTS: A significant reduction in hair was observed via trichoscopy following two sessions of treatment (p<0.001). A mean hair reduction of 80% was observed at week 4; however this returned to the previous state upon cessation of treatment. Acne grading decreased from 2.6 to 1.1 at week 8, and IPL treatment induced a significant reduction in melanin index after 2 weeks. The average values of the difference of R2 (Cutometer(R)) between IPL-treated areas and baseline were higher than those of the difference of R2 between control area and baseline. CONCLUSION: This home-use IPL device was effective for hair removal and treatment of acne, hyperpigmentation, and wrinkles.

Cutaneous Extraskeletal Ewing's Sarcoma / 대한피부과학회지

Extraskeletal Ewing's sarcoma is an extremely rare malignant soft tissue tumor, which presents the exact same histopathologic features with Ewing's sarcoma of bone. Tumor composed of small, blue, round cells with vesicular nuclei and scant cytoplasm is the characteristic histopathology of the disease. Extraskeletal Ewing's sarcoma is known to occur usually in the deep soft tissues of the extremities. We report a case of 22-year-old boy with solitary extraskeletal Ewing's sarcoma on his back without any evidence of bone involvement. The patient went through wide excision with meticulous lymph node dissection followed by chemotherapy. For the 15 months of follow up, there is not a sign of recurrence or metastasis observed.

Intravenous Immunoglobulin Treatment in a Child with Resistant Atopic Dermatitis

In a subgroup of patients suffering from atopic dermatitis (AD), treatment is quite difficult even after taking oral immunosuppressants. High-dose intravenous immunoglobulin (IVIG) treatment has been reported to be beneficial for them in a few uncontrolled trials. Herein we report a case of intractable AD in a 5-year-old girl who had significant clinical improvement after receiving 3 cycles of IVIG treatment (2 g/kg) without notable side effects. Since the first infusion of IVIG, the patient's skin lesions improved steadily and the improvement persisted until the 8-month follow-up. The eczema area and severity index score decreased remarkably, while immunologic parameters did not correlate with clinical improvement. This case suggests that IVIG therapy can be quite effective and safe for children with resistant AD.

Congenital and Multiple Hobnail Hemangiomas

Hobnail hemangioma (targetoid hemosiderotic hemangioma) is a vascular tumor affecting the limbs or trunk. Characteristically, the lesion has a "targetoid" clinical feature and dilated vascular spaces lined by hobnail endothelial cells at histologic examination. The age of onset is widely variable, form 5~67 years, typically occurring in young or middle-aged persons. It is usually apparent as a small solitary lesion. However, multiple lesions are identified sometimes. Herein, we report two cases of hobnail hemangioma in 7-year-old and 15-year-old males. Of note, the former case had a congenital lesion and the latter, multiple acquired lesions, which are both rare atypical presentations of the disease.

Pemphigus Foliaceus Associated with Psoriasis during the Course of Narrow-Band UVB Therapy: A Simple Coincidence?

Although psoriasis and bullous diseases are considered to be completely different disease entities, the literature has reported a few cases of psoriasis associated with bullous diseases, most of which are bullous pemphigoid. In limited cases, pemphigus foliaceus has also been reported in association with psoriasis. In most of them, pemphigus lesions usually developed on an untreated patient with a chronic history of psoriasis. Herein, we report a case of 53-year-old male with a chronic history of psoriasis who first developed generalized erosive lesions after 26 cycles of narrow-band ultraviolet B (NBUVB) therapy. A diagnosis of pemphigus foliaceus was made based on skin biopsy and direct immunofluorescence assay. Pemphigus lesions were well controlled with combination therapy of oral steroid and azathioprine. This is the first case where pemphigus foliaceus co-occurred with psoriasis during NBUVB therapy.
