Caring for the Involuntarily Hospitalized Adolescent: The Issue of Power in the Nurse-Patient Relationship

TOPIC: The power relations between involuntarily hospitalized adolescents and their caregivers from the viewpoint of theory development in nursing and the concept of medicalization. PURPOSE: To contribute to the development of nursing theories that can guide nursing care of involuntarily hospitalized adolescents by examining the power relations between the adolescents and their caregivers. SOURCES: Published literature in medical sociology, and nursing and psychiatric ethics. Nursing and psychiatric literature, in which Michel Foucault's theories are used to explicate the disciplinary power of psychiatry. CONCLUSIONS: To empower involuntarily hospitalized adolescents nurses must both recognize the inevitable power imbalance and seek guidance from the egalitarian ideals of nursing. Nurses can draw from postmodern thinkers who dismiss the idea that one theory can explain human relationships.     

Toxicity, inflammation, and anti-human immunodeficiency virus type 1 activity following exposure to chemical moieties of C31G.

C31G, which has potent activity against the human immunodeficiency virus type 1 (HIV-1) and an established record of safety in animal studies and human trials, is a microbicidal agent comprised of a buffered equimolar mixture of two amphoteric, surface-active agents: an alkyl amine oxide (C14AO) and an alkyl betaine (C16B). Studies of long-term in vitro exposure to C31G and its constituents have suggested that the components of C31G may contribute differentially to its toxicity and efficacy. In the present studies, in vitro assays of cytotoxicity and anti-HIV-1 activity demonstrated that C16B was slightly less cytotoxic compared to either C31G or C14AO, whereas the anti-HIV-1 activities of C31G and its individual constituents were similar. In the murine model of cervicovaginal microbicide toxicity, in vivo exposure to C14AO resulted in severe cervical inflammation followed by a delayed disruption of the columnar epithelium. In contrast, exposure to C16B caused severe cervical epithelial disruption and a secondary, less intense inflammatory response. These results demonstrate that (i) there are both mechanistic and temporal differences in toxicity associated with the components of C31G not necessarily predicted by in vitro assessments of cytotoxicity and (ii) contributions of each component to the anti-HIV-1 activity of C31G appear to be equal. In addition, these findings indicate that direct and indirect mechanisms of in vivo toxicity can be observed as separate but interrelated events. These results provide further insight into the activity of C31G, as well as mechanisms potentially associated with microbicide toxicity.
