    Notes: Abstract. The objective of our study was to clarify the radiologic spectrum of disease entities belonging to the SAPHO syndrome (SAPHO being an acronym for synovitis, acne, pustulosis, hyperostosis, and osteitis). A retrospective analysis of radiologic data was undertaken to determine the relationship of the osteoarthritic changes seen in palmoplantar pustulosis (PPP, n = 179), acne (n = 3), psoriasis vulgaris (PsV, n = 355), generalized pustular psoriasis (GPP, n = 25), and chronic recurrent multifocal osteomyelitis (CRMO, n = 4). Osseous changes of PPP, acne, and CRMO overlap each other; 7 PPP, 2 acne, and 3 CRMO patients manifested stenocostoclavicular hyperostosis as well as hyperostosis of the spine, pelvis, and/or femur. These findings were not seen in either PsV or GPP patients. Thirteen PsV and 4 GPP patients had peripheral arthritis and/or symmetrical sacroiliitis, which were not observed in the PPP, acne, and CRMO patients. The PPP, acne, and CRMO patients may be grouped as belonging to the single disease entity, namely SAPHO syndrome. Our findings do not support the inclusion of PsV and GPP in the spectrum of this syndrome.

    Notes: Abstract Cytochrome P450rm was previously isolated from the basidiomycete yeast Rhodotorula minuta as a bifunctional enzyme with isobutene-forming and benzoate 4-hydroxylase activities. We cloned the gene and corresponding cDNA for P450rm in order to characterize the enzyme in the context of fungal phylogeny and physiology. From the cDNA sequence, P450rm was deduced to have 527 amino acids with a calculated molecular weight of 59 136. P450rm shared 48% amino acid sequence identity with CYP53A1 from Aspergillus niger, indicating that the gene belongs to a novel subfamily of CYP53, CYP53B. However, the organization of the P450rm gene, which has eight exons and seven introns, differed completely to that of CYP53A1. Northern analysis demonstrated that the level of P450rm mRNA expression increased when L-phenylalanine was used as sole carbon source. These results suggest that P450rm has been well conserved during the evolution of fungi as a benzoate 4-hydroxylase in the dissimilation pathway starting from L-phenylalanine
