Skin diseases are associated with environmental factors and a public health approach is particularly important. We determined the prevalence of skin conditions and associated socioeconomic factors in primary school children in Turkey. A questionnaire for determining the socioeconomic level and a complete dermatologic examination were performed in 785 children in two primary schools in different socioeconomic areas of suburban and central Manisa, Turkey. The study included 345 (43.9%) girls and 440 (56.1%) boys with a mean age of 9.25 +/- 1.55 (range 6-14 years). Infectious skin diseases were frequently observed: pediculosis capitis in 74 children (9.4%), scabies in 17 (2.2%), viral skin diseases in 30 (3.8%), and fungal infections in 6 (0.7%). The other common conditions were melanocytic nevi (14.4%), keratosis pilaris (12.5%), pityriasis alba (12%), xerosis (11.8%), and atopic dermatitis (6.8%). Pediculosis capitis, acne, and dandruff were more common in girls. The rate of infections, atopic dermatitis, xerosis, and pityriasis alba were significantly higher in the school children with poor socioeconomic conditions. Improvement in socioeconomic conditions along with education may be needed to decrease the prevalence of some of these skin disorders in order to decrease costs related to treatment.
Loss of MMP-2, MMP-3 and FN in LP can be explained with the destruction of the epidermal basal layer. Similar expressions of MMP-2 and MMP-3 both in LP and DLE implied that these MMPs may be involved in the pathogenesis of interface dermatitis.
Psychocutaneous conditions are frequently encountered in dermatology practice. Prurigo nodularis and lichen simplex chronicus are two frustrating conditions that are classified in this category. They are often refractory to classical treatment with topical corticosteroids and antihistamines. Severe, generalized exacerbations require systemic therapy. Phototherapy, erythromycine, retinoids, cyclosporine, azathiopurine, naltrexone, and psychopharmacologic agents (pimozide, selective serotonin reuptake inhibitor antidepressants) were tried with some success. Here five cases with lichen simplex chronicus and four cases with prurigo nodularis, who responded well to gabapentin, are presented.
Lichen planus (LP) of the lips is a rare condition that is generally associated with other parts of the oral mucosa. Lip localization has an increased risk, since external trauma, smoking and ultraviolet light trigger malignant transformation. Only a few cases of isolated LP of the lips have been reported up to now, but results of larger series on oral LP suggest that it might be underestimated. Treatment of oral LP is usually difficult and lesions are generally resistant or recur, so that novel therapy alternatives are necessary. Here we report four cases of isolated LP of the lip successfully treated with imiquimod 5% cream. It was applied twice daily, 5 days a week, for 2 weeks. Two weeks after therapy, complete clinical and histopathological resolution was observed. No recurrence was observed during the 5, 10 and 18 months' follow-up period in cases 4, 3 and 1, respectively. Clinical and histopathological cure was also observed in case 2, but the patient showed clinical activation after 6 months. We suggest that imiquimod 5% cream is a safe and effective therapeutic treatment for oral LP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
