Inspiratory muscle function following abdominal weight exercises in healthy subjects.

Three indexes of inspiratory muscle function were evaluated in 20 healthy young adults before and after a six-week program of diaphragmatic breathing exercises. Thrice weekly, each subject performed 30 maximal voluntary diaphragmatic contractions in the supine position with a moderately heavy weight (range: 7-23 kg, or 15.4-50.7 lb) placed on the anterior abdominal wall to resist diaphragmatic descent. This protocol failed to improve 1) inspiratory capacity, 2) peak inspiratory flow rate, and 3) maximal pressures generated by the inspiratory muscles under static conditions. These finding indicated that this commonly used isotonic exercise regimen does not increase the maximal shortening, velocity of shortening, or strength of the diaphragm in healthy subjects. On the other hand, most subjects increased the maximal weight they found tolerable, performed the exercise more rapidly, and reported that their initial discomfort either waned or disappeared by the end of the program. These latter observations suggest that the exercise program might have improved inspiratory muscle endurance.

Ergotism treated with hyperbaric oxygen and continuous epidural analgesia.

Eight patients suffering from severe ergotamine-induced peripheral ischaemia were transferred to our institution for hyperbaric oxygen treatment after unsuccessful therapy in the primary hospital. The patients were exposed to 3 ATBS oxygen for 1 hour 2-3 times daily and they were given an epidural block for the purpose of analgesia where there was severe pain. The circulation and vitality of tissue were restored in all patients. One had tarsal amputations performed half a year later. Hyperbaric oxygen in combination with epidural analgesia is recommended in severe cases of ergotism.

Addicted mothers and their children: a case for coordinated welfare services.

Children of drug-addicted mothers are at an increased risk of premature birth, neonatal complications, developmental delay, understimulation, deprivation, neglect, abuse and even premature death. Research results from four Danish centres are presented and discussed. The material covers the period from 1970-1983. The studies clearly show a need for more coordinated support and services for these families and their children in order to prevent a new generation of 'social losers'.
