[Erythropoietin and transfusions in patients with anemia of chronic renal failure origin : an update view].

Aiming to know the factors that influenced the use of erythropoietin (EPO) in chronic hemodialysis patients, we retrospectively studied 82 patients (41 male), of whom 15 received EPO. No differences, between patients receiving or not receiving EPO, were found in age (46.9 +/- 25 and 57 +/- 13 years respectively), male/female ratio (9/6 and 32/35 respectively), time on dialysis (36.4 +/- 25.6 and 36.8 +/- 31.8 months respectively), dialysis hours (3.19 +/- 0.6 and 3.33 +/- 0.39 h respectively) and proportion of diabetics (6.6 and 20.8% respectively). Prior to EPO use and compared to untreated patients, treated patients were transfused with a higher frequency (60 vs 22%) and with more units/patients/years (0.12 vs 0.08). Hemoglobin levels at the start of the treatment was similar in treated and untreated patients (8.4 +/- 1.46 vs 8.78 +/- 1.97 g/dl). EPO was indicated in 11 patients due to general symptomatology associated to anemia and in 4 due to cardiac failure or angina. We conclude that EPO treatment is indicated in approximately 18% of patients in dialysis. An adequate dialytic treatment may achieve optimal hemoglobin levels with minimal transfusion requirements and without need of EPO, thus reducing costs.

Tracheal reconstruction.

Between 1983 and 1990 the authors treated 193 patients with laryngo-tracheal stenoses of diverse etiology. In 119 cases the stenoses was in the trachea. In 36 the stenoses extended to the subglottic region and in 1 case the carina was involved. The surgical procedure used in the tracheal stenosis was resection of the stenotic segment followed by end to end anastomosis. In most cases up to 6 cm of trachea could be resected. Two patients required a silastic prosthesis because the length of the stenotic area, 9 and 11 cm. The patient with the carinal involvement was treated by the insertion of a long Montgomery T tube. When the lesion included the subglottic area a partial resection of the cricoid cartilage and the damaged trachea was used. Associated surgical procedures had to be performed in order to close tracheo-esophageal fistulas, 2 cases, fixation of one of the vocal cords, 9 cases. Tracheal stenoses were cured in 90% of the cases with one surgical procedure, when the stenoses extended to the subglottic region, the cure rate was only 88.6%.
