RESUMEN
Background@#Lichen striatus (LS) is a linear, inflammatory dermatosis that mainly affects children. To date, there are limited data comparing treatment outcomes between topical agents for pediatric LS. @*Objective@#To investigate the clinical features and treatment outcomes associated with the use of topical agents for pediatric LS. @*Methods@#We retrospectively reviewed the medical records and clinical photographs of 60 pediatric patients classified into three groups according to the topical agent used. Treatment response was evaluated by comparing subjective symptoms and clinical photographs obtained at each visit. @*Results@#A good response (＞75% clinical improvement from baseline) was achieved in 55%, 46.2%, and 42.9% of patients from the calcipotriol, corticosteroid, and calcineurin inhibitor groups, respectively. There were no statistically significant differences in treatment duration among groups. However, when compared to other drugs, calcipotriol showed a trend towards shortening the disease course duration. @*Conclusion@#Topical use of calcipotriol, as well as corticosteroids and calcineurin inhibitors, may represent useful treatment options for pediatric LS, although further studies are required to confirm their efficacy and long-term safety.
RESUMEN
Hypomelanosis of Ito (HI) is a neurocutaneous disorder, also known as incontinentia pigmenti achromians. HI has been associated with chromosomal abnormalities, especially mosaicism. Herein, we report a case of HI with multiple congenital anomalies. A 2-month-old girl presented with multiple linear and whorling hypopigmentation on the face, trunk, and both extremities and patch alopecia on the scalp. Moreover, she had conical teeth, aniridia of the both eyes, and multiple musculoskeletal problems, including syndactyly and coccyx deviation. Cytogenetic analysis on peripheral blood was normal 46, XX, and no mutation was found in IKBKG gene test.

The methods for cartilage repair have been studied so far, yet many of them seem to have limitations due to the low regenerative capacity of articular cartilage. Mesenchymal stem cell (MSC) has been suggested as an alternative solution to remedy this challenging problem. MSCs, which have extensive differentiation capacity, can be induced to differentiate into chondrocytes under specific conditions. Particularly, this review focused on the effects of growth factors, cell-to-cell interactions and biomaterials in chondrogenesis of MSCs. Appropriate stimulations through these factors are crucial in differentiation and proliferation of MSCs. However, use of MSCs for cartilage repair has some drawbacks and risks, such as expression of hypertrophy-related genes in MSCs-derived chondrocytes and consequent calcification or cell death. Nevertheless, the clinical application of MSCs is expected in the future with advanced technology.
