Patients with vitiligo seem be less prone to the development of lentigines as a side effect of long-term photochemotherapy than do psoriatics. An 8-year-old boy who had a vitiliginous patch on his left thigh, had been receiving photochemotherapy since he was 2 years old. At the age of 3, multiple star-shaped brownish macules developed at the site of treatment. Photochemotherapy was continued until the patient was 6 year old, at which time no improvement in the vitiligo was seen, so photochemotherapy was discontinued. Now 2 years after treatment the lentigines still persist. On electron microscopic examination, the melanocytes showed two patterns of cell death: coagulative necrosis and apotosis together with atypical cytoplasmic and melanosomal alterations.

BACKGROUNDThe purpose of this study was to evaluate the efficacy of topical melagenine for repigmentation in child patients with vitiligo on the scalp.

METHODSTwenty-two child patients with vitiligo on the scalp were treated with 1.2 mg/ml aqueous melagenine in combination with 20 minutes of infrared exposure twice daily.

RESULTSIn 4 patients (18.2%), melagenine treatment in combination with infrared exposure led to complete recovery; in 6 patients (27.3%), treatment was shown to be effective; in 8 patients (36.3%), treatment led to improvements in patient condition; and only 4 patients (18.2%) showed no response after 1 - 2 treatment sessions. The general effective rate of melagenine-infrared combination treatment was 45.5% for the children with vitiligo on the scalp, and treatment was accompanied by minimal side effects.

CONCLUSIONMelagenine may be efficacious and a safe treatment option for childhood vitiligo affecting the scalp.

OBJECTIVEZiBuGanShenFang (ZBGSF) is a traditional herbal formula, which has showed an outstanding therapeutic effect on vitiligo clinically. Our aim is to investigate the influence of ZBGSF drug serum on the expression and activity of Tyrosinase in B16 cells, explore the mechanism of ZBGSF on Vitiligo treatment further.

METHODtyrosinase activity was measured by zymological methods, western blotting and RT-PCR were used to measure the protein content and mRNA level of tyrosinase and related proteins, respectively.

RESULTZBGSF drug serum had no effect on the proliferation of B16 cells. But it could promote Tyrosinase activity significantly and increase protein content and mRNA level of tyrosinase and related proteins in B16 cells.

CONCLUSIONPromoting the expression of tyrosinase protein and mRNA may be the elementary basis of ZBGSF on Vitiligo treatment.

OBJECTIVETo observe the difference in clinical efficacy on focal vitiligo treated with heat-sensitive moxibustion in comparison with medication, and discuss its effect mechanism.

METHODSSixty-eight cases were randomized into a moxibustion group (38 cases) and a medication group (30 cases). Additionally, 20 healthy persons were selected randomly as a normal group. In the moxibustion group, the heat-sensitive moxibustion was applied to Hegu(LI 4), Quchi(LI 11), Yanglingquan(GB 34), Zusanli(ST 36), Xuehai(SP 10) and the others, once a day. In the medication group, triamcinolone acetonide cream was used externally and locally, twice a day. In the two groups, the treatment of 15 days made one session. The efficacy was observed after continuous treatment for 3 sessions. The hemorheology test was done in all of the subjects. The radioimmunoassay was adopted to determine the levels of Interleukin 2 (IL-2), Interleukin 6 (IL-6), Interleukin 10 (IL-10) and tumor necrosis factor (TNF-alpha) before and after treatment.

RESULTSThe levels of IL-6, IL-10 and TNF-alpha in vitiligo patients were higher significantly than those in the normal group (P<0. 01, P<0. 05), the level of IL-2 was lower significantly than that in the normal group (P<0. 01) before treatment. After 3 sessions treatment, IL-2 level was increased significantly in the moxibustion group and the levels of IL-6, IL-10 and TNF-alpha were reduced, without significant differences as compared with the normal group (all P>0. 05). But the differences were significant as compared with those in the medication group (all P<0. 05). The curative and remarkably effective rate was 76. 3% (29/38) after treatment in the moxibustion group, which was higher significantly than 13. 3% (4/30, P<0. 05) in the medication group.

CONCLUSIONHeat-sensitive moxibustion achieves very good clinical efficacy on focal vitiligo, which is probably via promoting blood circulation and regulating the levels of IL-6, IL-10 and TNF-alpha.

Amelanotic acral melanoma is rare and difficult to diagnose, both clinically and pathologically. KIT mutations are frequently found in acral melanomas and are considered a risk factor for poor prognosis. The presence of vitiligo in melanoma has been reported, and KIT is thought to be partly responsible for the dysfunction and loss of melanocytes observed in vitiligo. We report a case of amelanotic subungual melanoma with multiple metastases that was associated with KIT mutation and vitiligo. An 85-year-old man presented with a 3-year history of a tender erythematous ulcerated tumor on the left third fingertip and developed hypopigmented patches on the face and trunk. Histopathological examination of the ulcerative tumor showed aggregates of tumor cells that were pleomorphic epithelioid cells. Immunohistochemical staining of the tumor cells was positive for S100, HMB45, and c-Kit. Histopathological findings from the hypopigmented patch on the face were consistent with vitiligo. Mutation analysis showed a KIT mutation in exon 17 (Y823D). The patient had metastasis to the brain, liver, bone, and both lungs. The patient refused chemotherapy, and died 3 months after the first visit.

OBJECTIVETo observe the therapeutic effect of Xiaobai Mixture (XBM) in treating vitiligo.

METHODSSeventy-four patients with vitiligo were randomly divided into the XBM group treated with XBM and the control group treated with 8-MOP. The therapeutic effect, nail-fold microcirculation, plasma endothelin-1, serum immunoglobulin were observed and compared.

RESULTSThe therapeutic effect of XBM was better than that of 8-MOP (P < 0.05). XBM could also obviously improve the nail-fold microcirculation, elevate the plasma endothelin-1 level and lower the serum IgG (P < 0.01).

CONCLUSIONXBM has superiority in treating vitiligo.
