The first goal of the therapy is to make the disease stable by preventing the appearance of new lesions. Drugs like oral corticosteroids, methotrexate, and azathioprine have been found effective in this phase. Objective: To compare the efficacy of oral corticosteroids, methotrexate, and azathioprine in patients with unstable vitiligo. Materials and Methods: It was a retrospective data analysis of 319 vitiligo patients, out of which 52 patients with unstable vitiligo who have received treatment in the form of 0.5 mg/kg oral corticosteroids on 2 consecutive days per week, 0.3 mg/kg methotrexate per week, and 1 to 1.5 mg/kg azathioprine daily were selected and were evaluated for the effect of drug for 12weeks. Results: There was no statistically significant difference in the appearance of new lesions in all 3 groups; however, methotrexate showed the early effect which plateaus after a few weeks whereas steroids as well as azathioprine showed a gradual and consistent effect. Conclusion: Methotrexate, steroids, and azathioprine all arrest the disease activity in vitiligo. Methotrexate can be used to arrest disease activity in fast-spreading vitiligo. Azathioprine can be used in patients with active vitiligo, wherever steroids are contraindicated.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"23 1","pages":"33 - 38"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87698885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sahoo","doi":"10.4103/pigmentinternational.pigmentinternational_50_21","DOIUrl":"https://doi.org/10.4103/pigmentinternational.pigmentinternational_50_21","url":null,"abstract":"Introduction: Melasma is a relatively common hypermelanotic disorder characterized by symmetrical light to gray-brown macules and patches involving photoexposed areas. Multiple factors have been implicated in the etiopathogenesis, including genetic factors, UV radiation, pregnancy, oral contraceptive pills (OCPs), thyroid dysfunction, and cosmetics. However, the role of cosmetics has not been well studied in melasma patients. The present study was designed to study the contact sensitivity to cosmetic allergens in patients with melasma. Material and Methods: Thirty patients with and thirty without melasma who visited Dermatology OPD between October 2015 and March 2017 were recruited according to selection criteria and were sequentially patch and photopatched with Indian cosmetic and fragrance series. Results: The mean age of melasma patients was 32.10 ± 6.62 years with female to male ratio of 1.72:1. Sixteen (53%) patients were found to show positive reactions on patch and photopatch testing with Indian cosmetic and fragrance series. Among 32 allergens tested, 15 allergens were found eliciting positive reaction. Thiomersol was the most common contact sensitizer eliciting positive reaction in six (38%) patients, followed by cetrimide, hexamine, and sorbitan each in three patients (19%). In the control group, only one (3.3%) subject showed positive contact allergy pattern. The results were significant (P < 0.001). Conclusion: A possible consideration of the pigmented cosmetic dermatitis and cosmetic contact sensitivity is recommended in the etiologic factors of melasma especially, in nonpregnancy/lactation induced melasma or when it is not associated with hormone therapy. Contact sensitizers might also have a role in melasma that is recalcitrant to all standard therapies.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"8 1","pages":"86 - 94"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89578842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On similar lines, salient nail changes are associated with pigmentary disorders, and can help toward diagnosis. Nail changes form a part of various physiologic pigmentary changes including racial pigmentation, pregnancy, or neonatal period. At the same time, a number of nail changes can be valuable clues toward disorders of pigmentation associated with genetic syndromes (Laugier–Hunziker syndrome, incontinentia pigmenti, and tuberous sclerosis), endocrine disorders, disorders of metabolism (alkaptonuria), infections (HIV-AIDS), internal malignancies, etc. Nail changes are especially useful if cutaneous pigmentary changes are suspected to be drug-induced based or associated mucosal and/or cutaneous hyperpigmentation. Various drugs that can cause cutaneous pigmentary alterations along with nail changes include cyclophosphamide, adriamycin, vincristine, docetaxel, paclitaxel, carboplatin, psoralens, hydroxyurea, bleomycin, etc. Nail changes are also associated with disorders of hypomelanosis, for example, vitiligo. Pigmentary changes due to endogenous and exogenous pigments are again diagnosable based on the nail changes they induce. This narrative review highlights the importance of nail changes in suspecting and diagnosing various disorders of pigmentation. It also points toward areas which need future research.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"26 1","pages":"76 - 85"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90826993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Giant congenital melanocytic naevus usually presents as a brown lesion, with flat or mamillated surface, well-defined borders and hypertrichosis. Dermoscopic examination of melanocytic naevi shows brown-blackish background, globules, reticular network and vascular structures.
