We have experienced a case of plexiform neurofibrorna of the right upper eyelid and orbit in a 12-year-old girl who had typical skin features of neurofibromatosis and no family history. The non-pulsating proptosis of the right eye and diffuse thickening with hypertrophy of the upper lid, had increased insiduciusly since the birth on. Biopsy taken from eyelirl lesion showed the features of plexiform neurofibroma. Skull X-ray and brain computerized tomogram showed that the right orbit was wider, with the enlarged mass and defects in orbital roof and lesser and greater wings of the sphenoid bone. The surgical excision of the right eyelid lesion was performed.

Objective: To examine the effects of Tribulus terrestris L. (T. terrestris) extract on the modulation of calcium channels to evaluate its use in topical agents for treatment of atopic dermatitis. Methods: The 70% methanol extract of T. terrestris was prepared. Human HEK293T cells with over-expressed calcium release-activated calcium channel protein 1 (Orai1), transient receptor potential vanilloid 1, or transient receptor potential vanilloid 3 (TRPV3) were treated with T. terrestris extract. Modulation of ion channels was measured using a conventional whole-cell patch-clamp technique. Results: T. terrestris extract (100 mg/mL) significantly inhibited Orai1 activity in Orai1-stromal interaction molecule 1 co-overexpressed HEK293T cells. In addition, T. terrestris extract significantly increased the TRPV3 activity compared with 2-Aminoethyl diphe-nylborinate (100 mmol/L), which induces the full activation of TRPV3. Conclusions: Our results suggest that T. terrestris extract may have a therapeutic po-tential for recovery of abnormal skin barrier pathologies in atopic dermatitis through modulating the activities of calcium ion channels, Orai1 and TRPV3. This is the first study to report the modulatory effect of a medicinal plant on the function of ion channels in skin barrier.

BACKGROUND: Osteoporosis results from bone loss due to menopause [estrogen(E) deficiency] and aging. Initial skeletal effect of menopause is accelerated bone resorption with an increase in seurm calcium(Ca) and compensatory but inadequate bone formation. Secretion of parathyroid hormone(PTH) is suppressed at this time. Postmenopausal osteoporosis results in fractures predominantly of trabecular bone, i.e., vertebra. With aging, secondary hyperparathyroidism by low serum Ca and vitamin D deficiency superim poses. Senile osteoporosis produces hip fractures, area of cortical bone. The aim of this study was to- examine the association of vitamin D[25(OH)D] and intact(i) PTH with bone mineral density(BMD) after controlling for suggested confounding factors, and the possibility of low serum vitamin D and high serum iPTH concentration could impact bone loss in Korean postmenopausal women. METHODS: Data from 188 postmenopausal Korean women aged 42 to 69 were analyzed through BMD, serum 25(OH)D, iPTH, Ca, phosphorus(P), alkaline phosphatase(ALP) and clinical characteristics. Factors affecting BMD was determined by Pearson correlation and the relationship between lumbar and femoral neck BMD and vitamin D[25(OH)D] and iPTH was assessed by multiple regression analysis after adjus- ting for suggested confounding factors. RESULTS: Lumbar and femoral neck BMD, serum Ca, P were decresaed and serum iPTH was increased with aging. In Pearson`s correlation, significant contributing factors to lumbar BMD was age, height, weight, menarche, year since menopause(YSM) and ALP. And significant contributing factors to femoral neck BMD was age, height, weight, menarche, YSM and iPTH. No relationship could be demonstrated between serum vitamin D[25(OH)D] and lumbar and femoral neck BMD. How ever, after controlling for potential confounding factors, a correlation was found between vitamin D[25(OH)D] and both of lumbar (p=0.013) and femoral neck BMD(p=0.077). iPTH was inversely related to femoral neck BMD(p=0.004) only in multiple linear regression. CONCLUSION: Serum vitamin D[25(OH)D] was influencing both of vertebral and femoral neck BMD, which suggests a significant role of vitamin D deficiency in the pathogenesis of postmenopausal osteo- porosis. In age related remodeling and loss of bone, increased serum iPTH might have additive role in cortical bone of femur. These findings suggest that vitamin D is very important for optimal bone health and a deleterious effect of increased iPTH on cortical bone loss. Adequate calcium and vitamin D status have to be maintained to prevent osteoporosis in postmenopausal Korean women.

We report herein a case of dysplastic nevus, which developed on the snterior chest and abdomen in a 48-year-old American Catholic priest. Clinical features present as brownish to pinkish patches with irreguar border fading into surrounding skin, ranging from 0.5 to 1.5cm in diameter. Histopathological findings show disordered proliferation of slightly atypical melanocytes in the epidermis and fusing of epidermal rete ridges, concentric eosinophilic fibrosis along elongated rete ridges, lymphohistiocytic infiltration in the dermis, and extension of intraepidermal melanocytic hyperplasia beyond the shoulders of dermal nevus component. One year follow-up revealed no evidence of recurrence.

We report herein a case of transient acantholytic dermatosis. The patient was a 24-year-old pregnant woman in the last trimester, who had pruritic, discrete, erythematous or brownish papules on the lateral aspect of the neck. Histopathologic findings of the skin lesion showed changes resembling Darier's disease showing well circumseribed, small foci of acantholysis with acantholytic and dyskeratotic cells over the suprahasal clefts. The patient showed good response to isotretinoin(Roaccutane) therapy, 20mg/day, for 30 days.

A 24-year-old female was seen with multiple, pinkish to skin colored and brownish to black pigmented macules, papules, patch and plaque on the face, neck, upper chest, extensor surface of both forearms and dorsal hands. Histopathological diagnoses from the 75 skin biopsy specimens taken during the follow-up period of 22 months include 29 skin tumors : one malignant melanoma, one precancerous melanosis, 16 basal cell carcinamas, four squamous cell carcinomas, four actinic keratoses, one melanoacanthoma, one keratoacanthoma and one angiofibroma. It was discussed that melanoacanthoma would be considered as the one of the associated beniign skin tumors in xeroderma pigmentosum.
