Q: Abstract: Sera from 101 patients with progressive systemic scleroderma were analyzed for circulating aminopropeptides of type III collagen using a radioimmunoassay which measures the intact and degraded forms (Fab assay). About 41% of the patients were found to have values above the normal range. A good correlation was observed between elevated levels of aminopropeptides and the degree of involvement of the skin and internal organs in the patients. Most patients (89%) with an active progression of the disease but not those in a stationary phase showed increased serum levels of aminopropeptides. Treatment with corticosteroids apparently normalized the levels of aminopropeptides. Only minor changes were observed with an antibody-based radioimmunoassay which measures primarily the intact form of the aminopropeptide.

Q: Abstract: The alternative or classical pathways for complement system component C3 may be triggered by microorganisms and antigen-antibody complexes. In particular, an activated fragment of C3, C3b, covalently attaches to microorganisms or antigen-antibody complexes, which in turn bind to the C3b receptor, also known as complement receptor 1. The genes encoding the proteins that constitute the C3-activating enzymes have been cloned and mapped to a "complement activation" locus in the major histocompatibility complex, and we demonstrate in this study such a locus on the long arm of chromosome 1 at band 1q32.

Q: Abstract: Three clinicopathologic cases with a remarkable pattern of extensive diffuse subependymal periventricular spread of cerebral metastases from solid systemic cancer are reported. Two patients had a small cell carcinoma of the lung. In the third case, the histologic features of the brain metastases were consistent with a neuron-specific enolase-positive, small cell anaplastic carcinoma. Involvement of the choroid plexus and leptomeninges was moderate or absent. Intraparenchymatous nodular metastases were not found except in one case in which rare nodular superficial cortical metastases were present. The clinical data were nonspecific except for orthostatic hypotension, in one patient, which was probably due to the infiltration of the floor of the third and fourth ventricles. Results of the cerebrospinal fluid examination, available in two cases, were normal. The only diagnostic investigation was contrast-enhanced computed tomography scanning.
