Annals of Dermatology 2017;29(1):91-94
Focal dermal hypoplasia, caused by mutations in PORCN, is an X-linked ectodermal dysplasia, also known as Goltz syndrome. Only seven cases of unilateral or almost unilateral focal dermal hypoplasia have been reported in the English literature and there have been no previously reported cases in the Republic of Korea. A 19-year-old female presented with scalp defects, skin lesions on the right leg and the right trunk, and syndactyly of the right fourth and fifth toes. Cutaneous examination revealed multiple atrophic plaques and a brown and yellow mass with fat herniation and telangiectasia that was mostly located on the lower right leg. She had syndactyly on the right foot and the scalp lesion appeared to be an atrophic, membranous, fibrotic alopecic scar. A biopsy of the calf revealed upper dermal extension of fat cells, dermal atrophy, and loss of dermal collagen. A diagnosis of almost unilateral focal dermal hypoplasia was made on the basis of physical and histologic findings. Henceforth, the patient was referred to a plastic surgeon and an orthopedics department to repair her syndactyly.

BACKGROUND: Rhus verniciflua Stokes (RV) has traditionally been used in Korea as an indigenous food (Rhus chicken soup) and as an herbal medicinal plant. While the anticancer, antimicrobial, and anti-inflammatory properties of RV have been actively studied in the medical field, its antioxidant effects in the skin that resist the reactive oxygen species in keratinocytes and fibroblasts is less understood. OBJECTIVE: We designed to evaluate the effects of R. verniciflua Stokes extract (RVE) on the photo-aged skin by an in vitro experiment using human fibroblasts and an in vivo experiment using a photo-aged murine model. METHODS: For the in vitro experiments, human fibroblasts irradiated with ultraviolet (UV) B were treated with RVE or vehicle, and the growth levels and the expression level of type 1 procollagen were compared. For the in vivo experiment, photo-aged mice irradiated with UVB and UVA were administered drinking water with or without RVE, and histological changes and the expression level of type 1 procollagen and matrix metalloprotease (MMP)-13 were compared. RESULTS: In vitro experiments using fibroblasts irradiated with UVB showed that RVE promoted growth and significantly increased the expression of type 1 procollagen as compared to the control group. In the photo-aged mice, RVE increased collagen content in the dermis and promoted the synthesis of type 1 procollagen without any visible decrease in MMP-13 as compared to control group. CONCLUSION: In addition to the previously reported antioxidant effects of RVE, oral intake of RVE effectively inhibited photo-aging in hairless mice by enhancing collagen synthesis.

7.Therapeutic Efficacy of a Combination Therapy of Topical 17α-Estradiol and Topical Minoxidil on Female Pattern Hair Loss: A Noncomparative, Retrospective Evaluation.

BACKGROUND: A variety of agents have been used to treat female pattern hair loss (FPHL), including topical minoxidil, topical 17α-estradiol, oral anti-androgen agents, and mineral supplements. Compared with these single agent regimens, combination therapies could be a better therapeutic option in expectation of superior treatment outcome. OBJECTIVE: This study was designed to determine the efficacy of a combination therapy consisting of topical 0.025% 17α-estradiol and 3% minoxidil in Korean patients with FPHL. METHODS: Therapeutic efficacy was evaluated in 34 women who applied topical 0.025% 17α-estradiol and 3% minoxidil once daily for more than 6 months. Phototrichogram analysis was performed before and after therapy. The efficacy was evaluated with respect to total hair count, hair caliber (as assessed by phototrichogram analysis), and photographic assessment. RESULTS: Total hair count and hair caliber both increased from baseline to 6 months in patients treated with the combination therapy of topical 0.025% 17α-estradiol and 3% minoxidil (p<0.001). Photographic assessment also revealed significant disease improvement, thus supporting the therapeutic efficacy. CONCLUSION: A combination therapy consisting of topical 0.025% 17α-estradiol and 3% minoxidil can be tried as an effective treatment for FPHL.

Korean Journal of Dermatology 2017;55(7):435-439
Vulvar vestibular papillomatosis (VVP) is a benign condition that can be viewed as the female equivalent of male pearly penile papules. Clinically, VVP is quite often misdiagnosed as condyloma acuminatum. As opposed to condyloma, VVP lesions arise from a distinct mucosal base, match the color of the surrounding mucosa, show symmetrical distribution, and are limited to the inner aspect of the labia minora. Although VVP is quite well known in the gynecological field, this disease entity is not commonly recognized in dermatology settings. Furthermore, a literature search for VVP revealed only nine reports in dermatological journals including one report from Korea. Therefore, through our report we wish to create awareness among dermatologists regarding the occurrence of this frequent but often ignored entity. Recognizing and understanding that papillomatosis of the vulvar vestibule is a normal variant will help dermatologists to avoid incorrect diagnosis and repeated unnecessary treatment.

Background:
Several biomarkers are measured in the interstitial fluid (IF) obtained from suction blisters that are used by dermatologists. As abnormal lipid levels can cause health problems, several studies have investigated the composition and distribution of lipids and lipoproteins in IF. However, to date, no study has focused on examining lipid profiles in the postprandial state.
Objective:
This study aimed to compare postprandial changes in serum lipid profiles and IF obtained from suction blisters and investigated their correlation.
Methods:
Fasting and postprandial levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides were measured in paired serum samples. IF was obtained from suction blisters from 20 healthy men using enzymatic-colorimetric methods.
Results:
The IF/serum ratios of TC, HDL-C, and LDL-C remained unchanged postoperatively. Postprandial levels of HDL-C and LDL-C decreased in the serum but not in IF. In both fasting and postprandial states, TC, HDL-C, and LDL-C levels in the serum were positively correlated with those in the IF.
Conclusion
The results of this study showed that lipoprotein cholesterol levels measured from suction blister fluids could be used as a biomarker to predict their serum levels regardless of food intake. Therefore, suction blister fluid sampling can be considered as a method to monitor serum lipid concentrations.
