Illustrated histopathologic classification criteria for selected vasculitis syndromes. American College of Rheumatology Subcommittee on Classification of Vasculitis.

We describe the histopathologic criteria for the diagnosis of 7 selected vasculitis syndromes: polyarteritis nodosa, Churg-Strauss syndrome, Wegener's granulomatosis, hypersensitivity vasculitis, Henoch-Schönlein purpura, giant cell (temporal) arteritis, and Takayasu arteritis. The criteria apply to the stereotypical cases in each category; they were formulated after a review of submitted biopsy material from 278 of the 1,000 patients entered into the American College of Rheumatology Vasculitis Study Registry, and from prior experience with the pathologic diagnosis of vasculitis in 1,079 nonregistry patients.

Comparison of the ICD-10-classification with the ICD-9- and the DSM-III-classification of mental disorders.

The diagnostic concepts in ICD-10 show better congruence with those in DSM-III than with those in ICD-9. The diagnostic definitions used by ICD-10 and DSM-III for the majority of diagnoses turn out to be similar; the definitions of anxiety disorders and schizoaffective disorders are, however, still at variance. Consequently, the empirical results from the WHO field trial in German-speaking countries reveal a high degree of overlap between the two systems; the degree of overlap between ICD-9 and ICD-10 was lower, but still surprisingly high overall. These empirical results support the validity of ICD-10.

Relation of serological- and CPE- classification of porcine enteroviruses to the classification by immunoperoxidase (IP) staining, and observation of CPE by IP staining method.

Characteristics of CPE produced by porcine enteroviruses (PEV) were examined by Immunoperoxidase (IP) staining method. Viral antigens were detected earlier than appearance of CPE. Distinctive characteristics of the three CPE types were clearly showed by the method. In cross reactions by IP staining, the titers of the staining were high (1:6,400 to 1:25,600), even though neutralizing titers of PEV with CPE II or III were low (1:200 to 1:400). The very close relationship was detected between PEV with the same CPE type, but the very low relationships were detected between PEV with the different CPE type. The relationships in CPE I group were various. The results by IP staining were more relative to CPE type than the serotype. Thus, IP staining is one method to classify PEV clearly.
