Haplotype structures of the UGT1A gene complex in a Japanese population.

Genetic polymorphisms of UDP-glucuronosyltransferases (UGTs) are involved in individual and ethnic differences in drug metabolism. To reveal co-occurrence of the UGT1A polymorphisms, we first analyzed haplotype structures of the entire UGT1A gene complex using the polymorphisms from 196 Japanese subjects. Based on strong linkage disequilibrium between UGT1A8 and 1A10, among 1A9, 1A7, and 1A6, and between 1A3 and 1A1, the complex was divided into five blocks, Block 8/10, Block 9/6, Block 4, Block 3/1, and Block C, and the haplotypes for each block were subsequently determined/inferred. Second, using pyrosequencing or direct sequencing, additional 105 subjects were genotyped for 41 functionally tagged polymorphisms. The data from 301 subjects confirmed the robustness of block partitioning, but several linkages among the haplotypes with functional changes were found across the blocks. Thus, important haplotypes and their linkages were identified among the UGT1A gene blocks (and segments), which should be considered in pharmacogenetic studies.

Balanitis of Zoon.

A patient with an eruption of clinical and histologic features typical of plasma cell orificial mucositis of the glans penis is reported. Immunohistologically, IgE and IgG are found to be major immunoglobulin classes in the plasma cellular infiltrate. Although specific allergen has not been identified yet, the present findings suggest that this condition is not a nonspecific inflammatory response but is related to immediate hypersensitivity.

Streptococcus milleri infection and pericardial abscess associated with esophageal carcinoma: report of two cases.

We report 2 cases of esophageal carcinoma with esophago-mediastinal fistula that developed pericardial abscess due to Streptococcus intermedius infection. Streptococcus intermedius, a generally harmless commensals in healthy humans, is not usually associated with infections of the oral cavity but may account for non-oral purulent infections. This report, however, highlights that Streptococcus intermedius infection can be life-threatening for some patients such as those with esophageal carcinoma with fistula.
