We show NP-completeness for the recognition problem of 2-line-bend graphs.

We show that the decision versions of the puzzles Knossos and The Hour-Glass are complete for NP.

We prove that playing Candy Crush to achieve a given score in a fixed number of swaps is NP-hard.

Proof systems for the Relativized Propositional Calculus are defined and compared.

The method in this paper is wrong.

Amar Mukherjee

We present a deterministic polynomial-time algorithm that solves the 3-satisfiability problem.

Philippe Moser

We show that BPP has either SUBEXP-dimension zero (randomness is easy) or BPP=EXP (randomness is intractable).

SUMMARY Liver involvement in autoimmune polyglandular syndrome (APS) in the form of chronic active hepatitis has been well described. However, to our knowledge, primary biliary cirrhosis in APS has not been reported. Here we report the case of a 27‐year‐old man who presented with classical insulin‐dependent diabetes mellitus and subsequently developed Hashimoto's thyroiditis, hypogonadism, and primary biliary cirrhosis. The latter diagnosis was confirmed by a cholestatic pattern of liver enzymes, positive anti‐mitochondrial antibody, normal cholangiogram, and characteristic liver biopsy findings. Primary biliary cirrhosis should probably be regarded as a possible, though uncommon, component of APS.
