The potential of computer-based psychiatric information systems is still largely undeveloped. Conceptual, technical, cost, and procedural problems have limited the impact of computers, but there are programs that have been successful or that show promise. While changes in the philosophy of psychiatric computer applications are on-going, a cost-effective, widely available clinical computer system has been developed.

To identify Fc receptors from human placental microvilli, proteins that were liberated by detergents from human placental synctiotrophoblast microvillous membranes (StMPM) were characterized by their abilities to bind human IgG in immune complexes with sheep or goat anti-human IgG and to monomeric rabbit anti-dinitrophenol (DNP) IgG bound to DNP-lysine Sepharose. Three placental IgG-binding proteins coprecipitated with immune complexes (Mr = 68,000, 52,000-56,000, 40,000) and were designated pIBP68, pIBP56 and pIBP40, respectively. Of the three proteins only pIBP56 bound to immobilized monomeric rabbit IgG. It was isolated from detergent lysates of StMPM and LDS/phenol glycoprotein extracts of placental plasma membranes suggesting that pIBP56 was a glycoprotein FcR previously reported (Mikulska et al, 1982). The binding specificities of pIBP56 and pIBP40 appeared to be detergent dependent. Photoaffinity crosslinking of StMPM surface proteins in situ to monomeric rabbit derivatized with N-succinimidyl(4-azidophenyl)-I, 3-dithiopropionate identified IgG-binding proteins identical in size to pIBP56 and pIBP40. Crosslinking further suggested that monomeric IgG covalently bound to a complex of StMPM proteins with a total size of 110,000-120,000 Mr. The findings suggest that pIBP68, pIBP56 and pIBP68 are responsible for IgG binding activity of placental StMPM.

This study, based on a sample of 172 children, examined the relation between average afternoon salivary cortisol levels measured at home at age 4.5 years and socioemotional adjustment a year and a half later, as reported by mothers, fathers, and teachers. Cortisol levels were hypothesized to be positively associated with withdrawal-type behaviors (e.g., internalizing, social wariness) and inversely related to approach-type behaviors, both negative and positive (e.g., externalizing, school engagement). Higher cortisol levels at age 4.5 predicted more internalizing behavior and social wariness as reported by teachers and mothers, although child gender moderated the relation between cortisol and mother report measures. An inverse relation was found between boys' cortisol levels and father report of externalizing behavior. A marginal inverse relation was found between child cortisol levels and teacher report of school engagement. Behavior assessed concurrently with cortisol collection did not account for the prospective relations observed,suggesting that cortisol adds uniquely to an understanding of behavioral development.
We performed a randomized controlled study to evaluate computer-based cognitive behavioral therapy in 36 patients who met Research Diagnostic Criteria for major or minor depression. Patients were randomly assigned to the computer, to a therapist, or to a control group placed on a waiting list. As determined by three measures of depression (the Beck inventory, the Hamilton rating scale, and the Symptom Checklist-90-R), both treated groups had improved significantly more than the control group at the end of the treatment period and 2 months later. The treated groups did not differ from each other at either time.
