Effect of budesonide on pulmonary hyperinflation in young asthmatic children.

In 19 asthmatic children, aged 2-6 years, the effect of six weeks' treatment with inhaled budesonide or placebo on functional residual capacity (FRC--helium dilution) and bronchodilator responsiveness was assessed in a double blind, randomised crossover trial. FRC was increased in most children at the start of treatment. Treatment with budesonide was associated with a reduction in FRC by comparison with placebo (median change 9% v 0%; p less than 0.05). There was a trend towards a greater response to a bronchodilator after budesonide. The results suggest that inhaled corticosteroids reduce hyperinflation in young asthmatic children.     

Nighttime bracing for adolescent idiopathic scoliosis with the Charleston bending brace. Preliminary report

The authors report their preliminary experience with the Charleston bending brace for the treatment of adolescent idiopathic scoliosis. This brace holds the patient in the position of maximum side bend correction and is worn only at night. Patients in this prospective multicentered study met all the following criteria: skeletal immaturity (Risser 0, 1+, or 2+), curvature greater than 25 degrees before bracing, no prior treatment, and greater than 1-year follow-up since initiation of treatment. There were 191 structural curves in the 139 patients. One hundred fifteen patients (83%) showed improvement or less than 5 degree change in curvature. Twenty-four patients (17%) demonstrated an increase in curvature greater than 5 degrees. Based on these preliminary results, continued use of bending brace treatment at nighttime only is justified for adolescent idiopathic scoliosis. Patients with double curves should be observed closely for increase in compensatory curves.

In this admittedly preliminary view of the future, the authors present a number of new concepts in MR imaging and consider their possible advantages and limitations.     

Improving recovery following cardiac surgery: a randomized clinical trial*

To enhance individual and family health during recovery from heart surgery, this study employed nursing interventions based on self-efficacy and family stress theory during the hospitalization period and for 3 months thereafter. The effectiveness of the interventions were assessed through a randomized trial in which 67 prospective bypass and valve surgery patients, aged 30-77 years, and their spouses, were allocated either the experimental interventions or usual care and followed for 6 months. At 3 months post-surgery, the only statistically significant differences between the experimentals and controls were on perceived self-efficacy for lifting and tolerating emotional distress. At 6 months no significant differences were found on individual or family measures. Analyses revealed that age, gender and preoperative cardiac status significantly affected individual recovery. The study is continuing with a larger sample in order to explicate the recovery process and to better determine whether a low intensity nursing intervention can effect changes in individual and family recovery.     

Differential mood changes following basal ganglia vs thalamic lesions

Patients with computed tomographic scan-verified unilateral lesions in the basal ganglia or thalamus were examined for the presence of poststroke mood disorders. Patients with left-sided basal ganglia lesions (mainly in the head of the caudate nucleus) showed a significantly higher frequency and severity of depression, as compared with patients with right-sided basal ganglia or thalamic (left- or right-sided) lesions. Results suggest that damage to biogenic amine pathways and/or frontocaudate projections may play an important role in the modulation of mood.     

Insulin-induced factitious hypoglycemic coma

Hypoglycemia due to the ingestion of oral hypoglycemic agents or injection of insulin is a common way for chronic factitious disorder to present to physicians. Despite this fact, factitious hypoglycemic coma is rare. Because hypoglycemia is potentially fatal, with numerous sequelae, physicians need to be aware of its occurrence and method of detection. A case of chronic factitious disorder presenting as hypoglycemic coma is presented and its implications discussed.
