Zusammenfassung: | Seventeen intravenous abusers of methadone underwent clinical, roentgenologic and physiologic assessment. Two complained of dyspnea on exertion and two had cor pulmonale. Of 15 patients whose fundi were examined, nine had talc particles in their retinal vessels. The chest roentgenograms of seven showed a diffuse pin-point micronodular pattern and two of the seven also manifested volume loss, one with coalescence of opacities simulating progressive massive fibrosis. Twelve patients had some degree of pulmonary dysfunction, 10 with lowered steady state diffusing capacity and 11 with decreased flow rates (FEV1 and MMF). There was no hyperinflation, but two showed an increase in residual volume. Corticosteroid therapy was attempted on two and was ineffective. Necropsy on the one patient who died revealed severe pulmonary fibrosis and talc granulomas in lungs, liver, kidneys and lymph nodes. |
