RESUMO

Human umbilical cord blood mesenchymal stem cells (hUCB-MSCs) are used in tissue repair and regeneration; however, the mechanisms involved are not well understood. We investigated the hair growth-promoting effects of hUCB-MSCs treatment to determine whether hUCB-MSCs enhance the promotion of hair growth. Furthermore, we attempted to identify the factors responsible for hair growth. The effects of hUCB-MSCs on hair growth were investigated in vivo, and hUCB-MSCs advanced anagen onset and hair follicle neogeneration. We found that hUCB-MSCs co-culture increased the viability and up-regulated hair induction-related proteins of human dermal papilla cells (hDPCs) in vitro. A growth factor antibody array revealed that secretory factors from hUCB-MSCs are related to hair growth. Insulin-like growth factor binding protein-1 (IGFBP-1) and vascular endothelial growth factor (VEGF) were increased in co-culture medium. Finally, we found that IGFBP-1, through the co-localization of an IGF-1 and IGFBP-1, had positive effects on cell viability; VEGF secretion; expression of alkaline phosphatase (ALP), CD133, and β-catenin; and formation of hDPCs 3D spheroids. Taken together, these data suggest that hUCB-MSCs promote hair growth via a paracrine mechanism.

RESUMO

BACKGROUND: Severe alopecia areata (AA) is resistant to conventional treatment. Although systemic oral corticosteroids are an effective treatment for patients with severe AA, those drugs have many adverse effects. Corticosteroid pulse therapy has been introduced to increase therapeutic effects and reduce adverse effects. However, the treatment modality in severe AA is still controversial. OBJECTIVE: To evaluate the effectiveness of corticosteroid pulse therapy in patients with severe AA compared with treatment with oral cyclosporine with corticosteroid. METHODS: A total of 82 patients with severe AA were treated with corticosteroid pulse therapy, and 60 patients were treated with oral cyclosporine with corticosteroid. Both groups were retrospectively evaluated for therapeutic efficacy according to AA type and disease duration. RESULTS: In 82 patients treated with corticosteroid pulse therapy, 53 (64.6%) were good responders (>50% hair regrowth). Patients with the plurifocal (PF) type of AA and those with a short disease duration (< or =3 months) showed better responses. In 60 patients treated with oral cyclosporine with corticosteroid, 30 (50.0%) patients showed a good response. The AA type or disease duration, however, did not significantly affect the response to treatment. CONCLUSION: Corticosteroid pulse therapy may be a better treatment option than combination therapy in severe AA patients with the PF type.

RESUMO

BACKGROUND: Medical skin care is essential for the treatment of skin diseases all over the world. Medical skin care is also part of medical practice and this must be differentiated from the simple skin care that is given for normal healthy skin. OBJECTIVE: We wanted to discuss medical skin care and the related medical devices and legal issues. METHODS: We reviewed the related laws and regulations, we consulted experts and associations and we analyzed the result of the survey. RESULTS: Legally, medical skin care and simple skin care are well classified. However, many illegal procedures are still performed by non-medical personnel and many adverse effects have been reported as a result. Furthermore, there are no legal restrictions for the performer based on the grade of each medical skin care procedure. CONCLUSION: For the best results and safe procedures, medical skin care must be performed by approved medical equipment under the supervision of a physician or medical personnel. Continuous control and guidance by the government is strongly needed.

RESUMO

A 49-year-old Caucasian male patient suffered from fever general weakness and diffuse hair loss on the scalp for 3 days. Skin lesions showed erythematous scaly patches with pustules and erosions on the lower extremities and perianal region, and multiple ulcerations on the labial mucoas. A complete blood cell count revealed thrombocytopenia and leukopenia, which gradually worsened day after day (platelet: 29, 000/mm², WBC: 1,000/mm³). Candida albicans was isolated from the lesions of the oral cavity and lower extremities. Twelve days prior to the visit, he had taken etretinate Tegison®) P.O.25mg/day, prednisolone P.O. 50mg1dy and methotrexate P.O. 15mg/day for 5 days for the treatment of psoriasis. We presume that these adverse reactions may be synergistic adverse reactions, probably due to methotrexate and etretinate in consideration of the patient's history.

RESUMO

We report herein a case of acral lentiginous melanoma in a 65-year-old female. An about 2x3cm sized erythematous to brownish mass with central ulceration was located on the left heel accompanied by enlargement of the left inguinal lymph nodes. Histopathologic findings showed lentiginous proliferation of atypical melanocytes with pseudoepithliomatous hyperplasia and invasion of tumor cells from the epidermis into the dermis. Focal pigmented melanocytes were also noted. Complete surgical excision and chemotherapy with DTIC were done. Marked edematous swelling on the left lower leg was developed after 8 months and 1 month later she was expired.

RESUMO

We report a case of mycosis fungoides in a 37 year-old male patient who had relatively well defined, irregular, erythematous plaques covered with acales on the buttock, lower extremities, anterior chest and back. Histopathological findings showed epidermotropism and Pautrier microabscesses in the epidermis and infiltration of atypical lymphocytes in the upper dermis. Electron microscopic findings showed mycosis cells with convoluted nuclei and prominent nucleolei He had been received PUVA therapy combined with topical and systemic corticosteroid for 4 months. Skin lesions were improved markedly after treatment with total 262 joules/crn2 and then maintained with 14 joules/cm2 in every week.
