RESUMO
Two diagnostic systems are compared in a psychiatric outpatient population of 175 patients. The Present State Examination (PSE)-Catego system identified 121 patients (69%) as "cases," whereas DSM-III identified 152 patients (87%) as cases. The two systems converged in 115 patients, yielding a kappa coefficient of only .32. Approximately one third of the DSM-III cases that were not detected by the PSE-Catego system was due to the restricted coverage of the latter system; the remaining two thirds could be attributed to differences in threshold and time framing. Compared with DSM-III, the PSE-Catego system showed a strong bias toward depression, and the system was extremely insensitive to the detection of social phobias and obsessive-compulsive disorders. Only 58% of cases of depression and 46% of cases of anxiety were diagnosed by both systems. The results are compared with other studies, and some consequences are discussed.

A patient with agranulocytosis and myeloid marrow hypoplasia following a second exposure to propylthiouracil (PTU) was studied for antibodies against mature blood cells and bone marrow precursor cells. During the acute phase of the agranulocytosis, significant growth inhibition of the myeloid committed progenitor cells (CFU-GM) was found following incubation with complement, indicating the presence of in-vivo cell bound cytotoxic antibodies. Using immunofluorescence and complement dependent cytotoxicity techniques it was demonstrated that acute phase and recovery phase sera contained circulating antibodies, reactive not only with differentiated granulocytes and monocytes but also with myeloid and erythroid (BFU-E/CFU-E) progenitor cells. Complement dependent lysis of the progenitor cells was facilitated by preincubation with PTU. These results indicate that the agranulocytosis was mediated by a PTU dependent antibody that affected both mature blood cells and bone precursor cells.
