Extensive cutaneous iatrogenic Kaposi's sarcoma after bullous pemphigoid treatment with oral methylprednisolone: a rare Chinese case report.

Bullous pemphigoid (BP) is an autoimmune disease that requires immunosuppressive therapy. Systemic corticosteroids are considered the standard treatment for moderate-to-severe BP. Kaposi's sarcoma (KS) is a rare multifocal endothelial tumour that affects the skin, mucosa and viscera.

Modified Technique of Cultured Epithelial Cells Transplantation on Facial Segmental Vitiligo.

Background: Cultured epithelial cells transplantation is a known surgical technique for vitiligo.

Objective: To evaluate the factors influencing efficacy and safety of cultured epithelial cells transplantation in 9-month follow-up.

Methods: Demographic, clinical, and repigmentation outcomes were reviewed for patients with facial segmental vitiligo who had undergone cultured epithelial cells transplantation from November 2013 to July 2015 at the clinic of the Department of Dermatology, Huashan Hospital, China.

Toxic epidermal necrolysis: performance of SCORTEN and the score-based comparison of the efficacy of corticosteroid therapy and intravenous immunoglobulin combined therapy in China.

Toxic epidermal necrolysis (TEN) represents the most severe drug-related skin condition that is potentially life-threatening with no well-established treatments. The application of corticosteroid therapy is controversial, whereas recently intravenous immunoglobulin (IVIG) therapy is emerging as a promising new method. A severity-of-illness score for TEN (SCORTEN) has gained acceptance in some western countries.

HLA-B*58:01 allele is associated with augmented risk for both mild and severe cutaneous adverse reactions induced by allopurinol in Han Chinese.

Aim: Allopurinol is widely used as an effective urate-lowering drug and is one of the most frequent causes of cutaneous adverse drug reactions (cADRs). Recently, a strong association of HLA-B*58:01 with allopurinol-induced severe cADRs was identified. This study investigated the predisposition to different types of allopurinol-cADRs conferred by HLA-B*5801 in a Han population from mainland China.

Astaxanthin upregulates heme oxygenase-1 expression through ERK1/2 pathway and its protective effect against beta-amyloid-induced cytotoxicity in SH-SY5Y cells.

Astaxanthin (ATX), the most abundant flavonoids in propolis, has been proven to exert neuroprotective property against glutamate-induced neurotoxicity and ischemia-reperfusion-induced apoptosis. Previous study have revealed that ATX can rescue PC12 cells from Aβ(25-35)-induced apoptotic death. However, the mechanisms by which ATX mediates its therapeutic effects in vitro are unclear.
