History of electroconvulsive therapy in the United States in the last decades

Despite its acknowledged efficacy and safety in the treatment of patients with severe affective and psychotic illnesses, as well as extensive efforts at professional and public education, electroconvulsive therapy is a neglected treatment, its use in the U.S. being mainly restricted to academic and private hospitals. Widespread use between 1935 and 1960, a rapid decline following the introduction of psychoactive drugs, and a slow resurgence in clinical interest since 1975 characterizes its history. The use of ECT has been encouraged by repeated favorable evaluations and by new procedures which improve both its efficacy and its safety. The experience in the United States provides a lesson for other nations where its use is inhibited.     

Dystrophic kyphoscoliosis in neurofibromatosis type I: a report of two cases and review of the literature

As the Department of Defense initiates Tricare, its new system of integrated health delivery, outcome assessment will become increasingly important. Traditional outcomes have focused on disease and its more serious consequences, disability and death. Patient satisfaction is only recently emerging as an important measure of the quality of health care delivery. In this paper, we focus on patient satisfaction, exploring its historical roots, its evolution as an outcome measure, and its potential utilities and weaknesses in quality assessment.     

Discriminative Stimulus, Reinforcing, Physical Dependence, and Antinociceptive Effects of Oxycodone in Mice, Rats, and Rhesus Monkeys.

Despite oxycodone's (4,5-epoxy-14-hydroxy-3-methoxy-17-methylmorphinan-6-one) history of clinical use and the attention it has received as a drug of abuse, few reports have documented its pharmacology's relevance to its abuse or its mechanism of action. The purposes of the present study were to further characterize the analgesic effects of oxycodone, its mechanism of action, and its effects in terms of its relevance to its abuse liability. The results indicate that oxycodone had potent antinociceptive effects in the mouse paraphenylquinone writhing, hot-plate, and tail-flick assays, in which it appeared to be acting as a μ-opioid receptor agonist. It generalized to the heroin discriminative stimulus and served as a positive reinforcer in rats and completely suppressed withdrawal signs in morphinedependent rhesus monkeys. These results suggest that the analgesic and abuse liability effects of oxycodone are likely mediated through μ-opioid receptors and provide the first laboratory report of its discriminative stimulus, reinforcing, and morphine cross-dependency effects.

On data, methods, and theory: An epistemological evaluation of psychology.

Argues that psychology, in virtue of its strict hypotheticalism and faithful adherence to scientific conventionality, had foreclosed the possibility of discovery in its own practice. Psychology's "scientific" character has rendered it less scientific. In light of its ambiguous philosophical underpinning in the assumption of positivism and scientific realism, psychology has tended to disqualify other competing epistemologies out of hand; consequently, it has generated very little coherent theory. Psychology's extant failure to disambiguate its fundamental postulates, combined with its relative methodological exclusivity, has rendered it somewhat blind to its past and augurs poorly for its future. Transcendental realism is discussed as possibly a more apposite philosophical substrate, which, if understood and faithfully applied, would liberalize psychology epistemologically and render it more philosophically coherent.
