Tuan Quoc Nguyen appeals the District Court’s 1 pre-service dismissal, under 28 U.S.C. § 1915(e)(2)(B), of his 42 U.S.C. § 1983 action. Having carefully reviewed the record, we conclude dismissal was proper. Nguyen’s allegations regarding medical mistreatment did not state a constitutional violation. See Dulany v. Carnahan, 132 F.3d 1234, 1239 (8th Cir. 1997); Martin v. Sargent, 780 F.2d 1334, 1337-39 (8th Cir. 1985). Accordingly, we affirm. See 8th Cir. R. 47A(a).
