The effect of naloxone on schedule-induced and other drinking.

A dose-response study of the effect of naloxone on schedule-induced drinking confirmed that this type of drinking is resistant to the opiate antagonist at doses which depressed drinking induced by water-deprivation, hypertonic saline and salbutamol. Naloxone also failed to reduce intake of saline solution in the presence of scheduled food presentation. The findings support the suggestion that schedule-induced drinking is regulated by a system of neural control which differs from that involved in deprivation and other forms of drinking. It would appear that opiate receptors do not play a part in the regulation of schedule-induced drinking.

Crisis intervention and the prevention of institutionalization: an interrupted time series analysis.

In the context of the community mental health movement in Illinois, the evolution and development of a crisis intervention program aimed at avoiding state hospitalization and bringing more appropriate and efficacious resources to bear on the difficulties of the individual and/or family is described. This intervention program is characterized by a more active-seeking style of delivering mental health services. With the novel application of interrupted time series analysis to both the targeted and matched nonequivalent control communities the efficacy of this more active intervention in reducing the number of state hospital administrations diagnosed as "mentally ill" is highlighted. The cost/benefit to the taxpayer is also discussed.

Failure modes and effects analysis in clinical engineering.

Failure modes and effects analysis (FMEA) is a proactive quality assurance procedure that has been commonly used to address potential design flaws and product misuses during the design stage of a product's life. FMEA is becoming commonplace among manufacturing companies but is relatively unknown outside of manufacturing circles. One potential new application of FMEA is by medical device end-users who could address design or functional concerns specific to their situation. The continued increase in the amount and complexity of medical instrumentation necessitates an aggressive stance towards safety in each hospital, such as is recommended in this paper.

Lymphoma with large intracavitary metastasis to the heart. Report of a case.

A case if reported of a 2 1/2-year-old boy with an extensive filtration of the retroperitoneum, mediastinum, and almost every organ of the body with a very primitive type of tumor identified as a poorly-differentiated mixed histiocyticlymphocytic lymphoma. The right atrium was completely filled with a large intracavitary metastasis which caused obstruction of the venous return to the heart with subsequent death.

Admissions of injection drug users to drug abuse treatment following HIV counseling and testing.

The outcomes of counseling and testing programs related to human immunodeficiency virus (HIV) infection and risk of infection among injection drug users (IDUs) are not well known or understood. A counseling and testing outcome of potential public health importance is attaining admission to drug abuse treatment by those IDUs who are either infected or who are at high risk of becoming infected. The authors investigated factors related to admission to drug abuse treatment among 519 IDUs who received HIV counseling and testing from September 1987 through December 1990 at a men's prison and at community-based testing sites in Worcester, MA. By June 1991, 123 of the 519 IDUs (24 percent) had been admitted to treatment. Variables associated with their admission included a long history of drug injection, frequent recent drug injection, cleaning injection equipment using bleach, prior drug treatment, and a positive HIV test result. Logistic regression analyses, controlling for effects of recruitment site, year, sex, and area of residence, generally confirmed the associations. IDUs in the study population who were HIV-infected sought treatment or were admitted to treatment more frequently than those who were not infected. The results indicate that access to drug abuse treatment should be facilitated for high-risk IDUs and for those who have begun to inject drugs recently.
