Case ReportsTonsillar squamous cell carcinoma associated with dermatomyositis: the first 2 cases in Korea.
Dermatomyositis (DM) is an autoimmune disorder with idiopathic myopathy and characteristic skin manifestations that one often accompanied by an internal malignancy. The association between dermatomyositis and malignancy has been reported several times, although tonsillar carcinoma is extremely rare not only in far eastern populations but also in caucasian populations. We report two cases of Korean patients with dermatomyositis associated with tonsillar carcinoma.

Tumor necrosis factor (TNF-alpha) and C-reactive protein (CRP) are positively associated with the risk of chronic kidney disease in patients with type 2 diabetes.
Chronic low-grade inflammation may induce chronic kidney disease in patients with type 2 diabetes. This study investigated the relation between inflammatory biomarkers and chronic kidney disease in patients with type 2 diabetes, which has not yet been reported in Asian populations. ⋯ Our results suggest that CRP and tumor necrosis factor-alpha may be independent risk factors for chronic kidney disease in patients with type 2 diabetes. A causal mechanism of this association should be evaluated in a followup study of Korean patients with type 2 diabetes.

Short-term effects of combined serial casting and botulinum toxin injection for spastic equinus in ambulatory children with cerebral palsy.
The purpose of this paper is to test the hypothesis that combination therapy of serial cast and botulinum toxin type A (BTX-A) injection can further enhance the effects of a BTX-A injection in ambulant children with cerebral palsy (CP) who have an equinus foot. ⋯ The results of our study suggest that a serial casting application after BTX-A injection can enhance the benefits of BTX-A injection in children with cerebral palsy.

ReviewTranscriptional regulation of T helper 17 cell differentiation.
The third lineage of T helper subsets, Th17, has recently been identified as an IL- 17-producing CD4+ Th cell, and its functions and regulatory mechanisms have been extensively characterized in immune responses. Functional studies have provided evidence that Th17 cells are important for the modulation of autoimmune responses, such as chronic asthma, rheumatoid arthritis, inflammatory bowel diseases, and multiple sclerosis. ⋯ In addition, Th17 cells are controlled by several transcription factors such as RORgammat, IRF4, BATF, FoxP3, T-bet, PPARgamma, E-FABP, and SOCSs. This review focuses on the functions and regulatory mechanisms of several transcription factors in the control of Th17 cell differentiation.

ReviewGlioma pathogenesis-related protein 1: tumor-suppressor activities and therapeutic potential.
After glioma pathogenesis-related protein 1 (GLIPR1/Glipr1) was identified, the expression of GLIPR1 was shown to be down-regulated in human prostate cancer, owing in part to methylation in the regulatory region of this gene in prostate cancer cells. Additional studies showed that GLIPR1/Glipr1 expression is induced by DNA-damaging agents independent of p53. Functional analysis of GLIPR1 using in vitro and in vivo gene-transfer approaches revealed both growth suppression and proapoptotic activities for mouse Glipr1 and human GLIPR1 in multiple cancer cell lines. ⋯ Glipr1-related antitumor immunostimulatory activities were confirmed and extended in subsequent studies. Administration of a novel Glipr1 genemodified tumor cell vaccine had significant antitumor activity in a mouse model of recurrent prostate cancer. In conclusion, restoration of GLIPR1 function in prostate cancer cells through GLIPR1 gene-based or GLIPR protein-based delivery methods may provide a safe and effective approach for targeted therapy for a range of malignancies.
