A large strand of research has identified conditions on preferences under which (i) a single risk is undesirable and (ii) two independent risks aggravate each other. We extend this line of inquiry by establishing conditions such that (iii) the degree of mutual aggravation is greater for more severe risks. Here, the severity of risks is characterized by means of general stochastic dominance shif...

Although oral bacteria-associated systemic diseases have been reported, association between Streptococcus mutans, pathogen of dental caries, and ulcerative colitis (UC) has not been reported. We investigated the effect of various S. mutans strains on dextran sodium sulfate (DSS)-induced mouse colitis. Administration of TW295, the specific strain of S. mutans, caused aggravation of colitis; the ...

Capecitabine, present significant clinical benefits in the treatment of colon cancer. However, capecitabine treatment also results in unwanted cutaneous toxic side effects, such as hand-foot syndrome (HFS). Psoriasis aggravation is rarely reported as a side effect; however, it causes cosmetic issues in patients, which may result in the early termination of capecitabine treatment. Therefore, alt...

METHODS A 42-year-old male patient experienced head trauma resulting from flexion-hyperextension in...
