Despite severe pain, poor coping, and poor health status, almost all patients with NBS undergoing detoxification were able to stop using narcotics and have significant improvement in pain and coping. However, almost ½ reverted to narcotic use at 3 months. Those who stayed off narcotics showed greater improvement in pain scores. This study provides a rationale for treating patients with NBS by detoxification in order to improve their clinical status. Further work is needed to understand the reasons for the high recidivism rate.
In the last ten years there have been a number of studies reporting an association between certain persistent oral dyskinesias in elderly people (particularly women) and prolonged medication with phenothiazines. Many of the cases described in these studies also showed some evidence of brain damage and because of this it has often been suggested that brain damage is an important contributory cause of oral dyskinesia. Buccal factors such as the edentulous state have also been incriminated (Joyston-Bechal, 1965; Evans, 1965). However, very few controlled studies have been carried out. The literature on this subject has been well reviewed by Crane (1968) and Kline (1968).
Patterns of intermittent ventilation were recorded by means of long electromyogram wires from quiescent Blaberus craniifer (Burmeister) buried in vermiculite. While buried, cockroaches were subjected to perfusion with various mixtures of CO, in air and of oxygen in nitrogen. Quiescent cockroaches in air ventilated for mean periods of 138 s in cycles of 720 s duration, but much variability occurred within and between cockroaches. Mild hypercapnia or hypoxia shortened the overall cycle time while more severe treatment caused the cycle to be replaced by continual pumping. Intermittent ventilation persisted in decapitated insects but the threshold of the response to hypoxia or hypercapnia was elevated. Prevailing gas tensions normally determine the frequency and duration of each phase.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
