These macules are commonly aesthetically disfiguring, which may significantly decrease their quality of life. Common peoples’ misconceptions and undue apprehension associated with vitiligo are the result of inadequate knowledge about this otherwise benign and harmless condition. Aims and objectives: To document the prevalent knowledge, attitude, and practices of general population on vitiligo. Materials and methods: It is a cross-sectional study of 3 months duration. A total of 500 people from the general public visiting hospital who satisfied the inclusion criteria were recruited and were provided with a questionnaire devised in local language (Kannada) which included questions related to knowledge and attitude toward vitiligo patients. The collected data were tabulated and assessed using descriptive statistics. Results: Statistically significant difference was noted in mean knowledge and attitude score between urban and rural subjects (P = 0.008, P < 0.001), respectively. Regression analysis showed gender, education, and age are the predictors of knowledge (P = 0.001, P < 0.001, P < 0.001), respectively. Education and domicile were the predictor of attitude (P < 0.001, P < 0.001), respectively. Conclusion: The study highlights that the availability of the different treatment options in the urban areas has increased the knowledge and attitude of public toward the condition. Thereby we conclude that the need of the hour is awareness program regarding knowledge and treatment options of vitiligo.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"42 1","pages":"113 - 119"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90553264","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}

There are only a few studies on childhood onset vitiligo that describe its prognosis. Aim: To study the clinical and epidemiologic features of childhood onset vitiligo and to assess its impact on quality of life (QoL) of family members. Methods: A cross-sectional study was carried out on patients with vitiligo, with onset before 12 years of age. Clinicoepidemiologic profile was recorded. QoL of family members was assessed using family dermatology life quality index (FDLQI). Results: Fifty-four patients with age ranging from 1.2 to 41 years were included. Mean age of onset was 6.68 ± 3.43 years. Generalized vitiligo was most common (33.33%), followed by segmental (31.48%), acrofacial (24.07%), mucosal (7.40%), universal (1.85%), and focal (1.85%) types. About 42% had mucosal involvement, oral mucosa in 27.78%, and genital mucosa in 14.81%. Leukotrichia was significantly more common in segmental vitiligo (SV) than nonsegmental vitiligo (NSV) (P = 0.000046). Of the 9 adult NSV patients, progressive disease was reported in 6 with 10 years duration and 2 with 20 years duration. Mean FDLQI was 7.02 ± 3.64; emotional distress having maximum score (1.09). There was no significant association between total FDLQI and age (P = 0.69), gender (P = 0.528), clinical type (P = 0.874), vitiligo disease activity (VIDA) score (P = 0.105), or site of involvement (P = 0.07). Conclusion: NSV can be progressive for many years; a fact to be kept in mind while planning management of childhood onset vitiligo. QoL of family is affected regardless of the clinicoepidemiologic profile.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"14 1","pages":"30 - 36"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87642562","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}

Albinism occurs all over the world, with highest prevalence in sub-Saharan Africa. The most common type is oculocutaneous albinism (OCA), an autosomal recessive disorder. Albinism is associated with morbidity and mortality in Africans. This study aims to describe the epidemiology of OCA, clinical expressions, and effect on the quality of life (QoL). Methods: Individuals with albinism were invited through the albino foundations and dermatology clinic of Lagos University Teaching Hospital. Structured questionnaires were used to document demographic and clinical data: occupational history, sun exposure, sun protective behavior, knowledge of adverse effects of sun exposure, and QoL and features of photodamage. Results: A total of 142 Nigerians with albinism were recruited. The male to female ratio was 1:1.25. The median age was 22.5 and interquartile range 10.25 to 34. Knowledge of need for sun protection was found in 129 (90.8%): 81 (57%) had daily sun exposure and 61 (43%) had work exposure to sun. Use of sun protection was noted in 103 (72.5%). Overall, photodamage was found in 136 subjects (95.8%). Mean effect of albinism and photodamage on QoL was 6.34 ± 4.47 (standard deviation) corresponding to moderate effect on QoL and domain of “symptoms and feelings” was most affected. Conclusion: The prevalence of photodamage among people with albinism is high despite knowledge of sun protection. There is need for efforts on photoprotection by individuals with albinism and public health interventions.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"76 1","pages":"37 - 45"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86638683","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}

Even though different modalities of treatment available, it remains as a difficult disease to treat. Many cases remain stable after a period of medical therapy without any further response. For treating pediatric vitiligo, currently available and result providing therapies are limited. Surgical techniques are the only hope in such patients. Only limited studies are available regarding surgical interventions in childhood vitiligo. Aim: To evaluate the response of autologous, noncultured melanocyte–keratinocyte cell transplantation in childhood stable vitiligo. Methods: A retrospective analysis was conducted in 20 cases of stable localized childhood vitiligo (10 segmental and 10 focal) treated by autologous, noncultured melanocyte–keratinocyte cell transplantation. Serial photographs were taken from the first visit onwards. The patients were followed for a period of 4 years. The results were analyzed on a visual analog scale. Results: Out of total 20 cases, 11 had excellent (90–100%) response, 4 had good (60–89%), 2 had fair (25–59%), and 3 had poor response (0–24%). Age and sex of the patients and size and duration of lesions did not show significant influence on results of transplantation. Conclusion: This is a simple, safe, and effective surgical therapy for replenishing the missing melanocytes even in resistant cases of vitiligo. Only limited studies are there in childhood vitiligo. In spite of its invasive nature, it can be used to treat localized stable vitiligo in children.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"6 1","pages":"46 - 51"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76817208","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}

They are a bridge between drugs and cosmetics for minor skin ailments. The lack of proper regulatory standards for cosmeceuticals makes it very important for the dermatologists to educate the patient regarding their safety, or consequences of lack of knowledge thereof. In hyperpigmentation disorders, cosmeceuticals specifically target melanocytes and block the important regulatory steps in melanin synthesis, especially tyrosinase. The various agents include arbutin, bakuchiol, ferulic acid, kojic acid, licorice root extract, nicotinamide, plant extracts, resorcinol, retinol, sunscreens, thiamidol, and vitamin C. Plant extracts have minimal side-effects and are gaining popularity. They include aloe vera extract, cinnamic acid, coffeeberry, flavonoids, grape seed extract, green tea extracts, marine algae extract, mulberry extract, N-acetyl glucosamine, orchid extract, pycnogel, soy and umbelliferone. There is a requirement for large randomised controlled trials to establish their efficacy and adverse effects. Patient follow-up and compliance are the cornerstones of any skin therapy as any cosmeceutical use can produce gradual results when compared to conventional therapies. The PubMed database was searched using ‘hyperpigmentation disorders’ OR ‘melasma’ AND ‘cosmeceuticals’ as keywords. Abstracts were screened to include studies in the English language and those pertaining to the use of cosmeceuticals in hyperpigmentary disorders. In this review, we summarise the existing literature on the utility of cosmeceuticals in the treatment of hyperpigmentary diseases.","PeriodicalId":32636,"journal":{"name":"Pigment International","volume":"1 1","pages":"14 - 23"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86483016","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}
