A commercially available C1 inhibitor (C1-INH) concentrate was used for short-term prophylaxis before surgery in two patients with hereditary angioneurotic oedema. The patients suffered from recurrent subcutaneous and submucosal oedema of the face, extremities, and gastrointestinal tract as the result of a hereditary C1-INH deficiency. Both patients were receiving tranexamic acid or danazol therapy as oral long-term prophylaxis. ⋯ With this substitution treatment no specific symptoms of hereditary angioneurotic oedema were recognized in either case. The measurement of C1-INH plasma concentration 2 h or 4 h after C1-INH substitution showed a marked rise in both patients, though normal values were not reached in either. We suggest that infusion of C1 concentrate is an appropriate form of preoperative substitution treatment in patients with hereditary angioneurotic oedema, in view of the lower risk of infection than with infusion of fresh-frozen plasma and the observed effectiveness.

Fibrodysplasia ossificans progressiva (FOP) is a rare, congenital disease of the striated muscular system, ligaments and fascia; it leads to complete ossification in adult life. The disease usually begins in the first decade of life and is accompanied by abnormalities of the hands and feet that have already begun to occur at birth. There is no effective therapy. ⋯ The patient recovered well. Unfortunately, she died a few weeks later from suicide. The goal of this case report is to emphasize the value of the fibrobronchoscope in patients with FOP.
