Eighty Korean children (ages 8 months-12 years) with clinical and/or histopathologic diagnoses of vitiligo were evaluated; 39 boys and 41 girls. The mean age at first visit was 7.9 years and the mean age at onset was 5.6 years. The most common site of onset was the head/neck area (58.8%), followed by the trunk and lower limbs. The children were compared with a control group of 422 adults with vitiligo. Children comprised 16% of the total vitiligo patients and adults comprised 84%. A family histo

Our results indicate that striae distensae are a common skin condition that occurs early in puberty regardless of gender, and that they have a different anatomical distribution and relationship with body measurements in each gender.

Steatocystoma multiplex (SM) shares many clinical features and may show overlapping histopathological features with eruptive vellus hair cyst (EVHC). Clinical data and pathologic features of 64 patients with SM were evaluated in detail. Most of the cases were sporadic, with an average onset age of 26 years and distribution on the arms, chest, axillae, and neck. All cases exhibited eosinophilic cuticle and lack of granular layer, and 17-42% displayed vellus hair, hair follicles, keratin, and smoo

30 mg/day of beta-carotene supplementation is demonstrated to prevent and repair photoaging.

DBEs enable successful diagnostic and therapeutic ERCP in patients with a surgically altered anatomy of the upper gastrointestinal tract. It is a safe, feasible and less invasive therapeutic option in this group of patients. Standard 'long' DBEs have limitations of long working length and the need for modified ERCP accessories. 'Short' DBEs are equally as effective in reaching the target limb as standard 'long' DBEs, and overcomes some limitations of long DBEs to result in high success rates for

Background: No studies have yet been undertaken to determine the effect of aloe gel on the clinical signs and biochemical changes of aging skin. Objective: We wanted to determine whether dietary aloe vera gel has anti-aging properties on the skin. Methods: Thirty healthy female subjects over the age of 45 were recruited and they received 2 different doses (low-dose: 1,200 mg/d, high-dose: 3,600 mg/d) of aloe vera gel supplementation for 90 days. Their baseline status was used as a control. At ba

In an effort to find topical agents that prevent or retard cutaneous aging, seven functional lipids were screened for their procollagen-upregulating and matrix metalloproteinase (MMP)-1-downregulating activities in human dermal fibroblasts by Western blotting. The preventive effect on ultraviolet (UV)-induced decrease of procollagen was demonstrated in phosphatidylserine (PS), lysophosphatidylserine (LPS), lysophosphatidic acid (LPA), N-acetyl phytosphingosine (NAPS), and tetraacetyl phytosphing

Red ginseng contains many bioactive constituents, including various ginsenosides that are believed to have antioxidant, immunostimulatory, and anti-aging activities. Yet, no controlled human study has explored its effects on photoaged skin. This study determined whether long-term intake of a red ginseng extract-containing Torilus fructus and Corni fructus mixture reduces facial wrinkles and increases collagen synthesis in human skin. Healthy female volunteers over 40 years of age were randomized

Seventy-eight Korean patients with basal cell carcinoma (BCC) between 1984 and 1998 were retrospectively examined at Ewha Womans University Tongdaemun Hospital, Seoul, Korea. We analyzed the annual incidence, age and sex distribution, site of the lesions, clinical appearance, including the proportion of clinically pigmented tumors, modalities of treatment, incidence of recurrence and metastasis of the tumors, the histopathological patterns, and whether solar elastosis, microscopic pigmentation,

Lichen planus pigmentosus (LPP) has thus far been described as a condition of unknown etiology which clinically differs from the classical lichen planus (LP) by exhibiting dark brown macules and/or papules mostly in exposed areas and flexural folds and a longer clinical course without pruritus or scalp, nail or mucosal involvement. Histopathologically, LPP shows the typical changes seen in LP, but with thinning of epidermis. We report a case of LPP that developed in a unilateral, zosteriform pat

Oral supplementation of micronutrients, or functional foods, to prevent aging has gained much attention and popularity as society ages and becomes more affluent, and as science reveals the pathological mechanisms of aging. Aging of the skin combines biologic aging and extrinsic aging caused predominantly by sunlight and other environmental toxins. Anti-aging functional foods exert their influence mostly through their anti-oxidant and anti-inflammatory effects, thereby abrogating collagen degrada
