Intralesional immunotherapy of ano-genital warts with Mw vaccine seems to be a promising new approach, which needs to be evaluated in the randomized controlled trials.

Extracted hair follicular ORS cell suspension can be a useful simplified transplantation method for vitiligo. The transplantation procedure should be reserved for patients with vitiligo stable for at least 1 year. A larger study is needed for further evaluation.

The technique is inexpensive and easy and obviates the need of cumbersome and heavy equipment.

Vitiligo is a depigmenting disorder of the skin that is characterized by the loss of functional melanocytes from the lesional sites. Although the exact etiology is not understood, autoimmunity is thought to be a crucial deterministic factor. A recurring theme of several autoimmune disorders is the aberrant presentation of self-antigens to the immune system, which triggers downstream perturbations. Here we examine the role of alleles of HLA class I and class II loci to delineate vitiligo manifestation in two distinct populations. Our studies have identified three specific alleles, HLA-A*33:01, HLA-B*44:03, and HLA-DRB1*07:01, to be significantly increased in vitiligo patients as compared with controls in both the initial study on North Indians (N=1,404) and the replication study in Gujarat (N=355) cases, establishing their positive association with vitiligo. Both generalized and localized vitiligo have the same predisposing major histocompatibility complex alleles, i.e., B*44:03 and DRB1*07:01, in both the populations studied, beside the differences in the frequencies of other alleles, suggesting that localized vitiligo too may be an autoimmune disorder. Significant differences in the amino-acid signatures of the peptide-binding pockets of HLA-A and HLA-B α-chain and HLA-DR β-chain were observed between vitiligo patients and unaffected controls.

Background Noncultured epidermal cell suspension (NCES) is an effective surgical modality for stable vitiligo which involves transplantation of the basal layer of epidermal cells onto the dermabraded vitiliginous patch. Platelet-rich plasma (PRP) has growth factors which may stimulate melanocyte migration and proliferation of keratinocytes and fibroblasts. The objective of this study was to compare the extent of repigmentation achieved by transplantation of NCES suspended in PRP with that of NCES suspended in phosphate buffered saline (PBS).Methods Twenty-one patients of stable vitiligo with at least two lesions of comparable size were included. The two vitiligo patches were randomized to receive NCES suspended in PRP or PBS. Postoperatively after 1 week, patients were given heliotherapy for 15 minutes daily.Results At 6 months follow-up, mean repigmentation by area method in PRP arm was 75.6 AE 30% SD and in non-PRP arm was 65 AE 34% SD (P = 0.0036). Patient satisfaction by visual analogue scale at 6 months also showed better results in PRP arm (P = 0.001).Assessment by three independent observers showed better repigmentation in PRP side both at 3 and 6 months.Conclusions Suspending NCES in PRP can result in significantly greater mean repigmentation and patient satisfaction than suspending in PBS.

Use of chemotherapeutic drug cisplatin is limited because of its toxicity. Therefore, efforts continue for the discovery of novel combination therapies with cisplatin to reduce its effective treatment dose. This study evaluates the potential of fisetin, a flavonoid, to increase cisplatin cytotoxicity in human embryonal carcinoma NT2/D1 cells. Addition of fisetin to cisplatin enhanced cisplatin cytoxicity in vitro at four times lower dose than that required by cisplatin monotherapy for similar cytotoxic effects. Cisplatin, fisetin monotherapy, and addition of fisetin to cisplatin in a combination increased FasL expression. Cisplatin and fisetin as single agents activated caspases-8 and -3 and caspases-9 and -7, respectively, whereas combination treatment activated all 4 caspases. Increases in p53 and p21 and decreases in cyclin B1 and survivin occurred, all effects being more exaggerated with the combination. Fisetin, with or without cisplatin, increased expression of proapoptotic protein Bak and induced its mitochondrial oligomerization. Bid truncation and mitochondrial translocation of Bid and p53 was induced by fisetin in the presence or absence of cisplatin. Downregulation of p53 by short hairpin RNA during drug treatment decreased p21 levels but caused survivin increase, thus reducing cell death. Upstream to p53, inhibition of p38 phosphorylation reduced p53 phosphorylation and cell death. In a NT2/D1 mouse xenograft model, combination therapy was most effective in reducing tumor size. In summary, findings of this study suggest that addition of fisetin to cisplatin activates both the mitochondrial and the cell death receptor pathway and could be a promising regimen for the elimination of embryonal carcinoma cells.
