14 cases of mannitol-induced acute renal failure were reported. The dosage of mannitol used varied widely. In all cases serum Na+, HCO3- were decreased, K+ and BUN increased significantly. ⋯ Monitoring of serum osmolality or osmolal gap can help to prevent mannitol intoxication. The decrease of serum Na+ may be a warning sign of increased osmolal gap. Hemodialysis is the best way for the treatment of mannitol-induced acute renal failure.

The authors of this paper have reviewed 137 X-ray films of the involved feet and followed up 30 patients all of them suffering from heel pain treated in the authors' hospital during 1980-1985, in order to find out the relationship between the length, shape and the direction of the spurs with the heel pain. We have found: (1) There are no clear relationship between heel pain and the length, shape and the direction of the calcaneal spur. (2) The plantar soft tissue of the painful foot was thickened, indicating the heel pain was due to inflammation in the plantar soft tissue. (3) Heel pain is related to the patient's age and sex. (4) The spurs still exist and grow even bigger after the syndrome disappears.

[Hemodynamic effects of prostaglandin E1 in patients with congenital heart disease and pulmonary hypertension].
Investigations were performed to determine whether prostaglandin E1 (PGE1) would get a favorable change in pulmonary hymodynamics in patients with congenital heart disease and elevated pulmonary vascular resistance. Thirty-seven patients were studied. PGE1 was infused into the pulmonary artery with 100-200 ng/kg.min. ⋯ But PGE1 resulted in systemic hypotention in high-resistance group for the same dose (TPRO > 600 kPa.s/L). This study shows that PGE1 is an effective vasodilator. The doses and the effects of PGE1 are dependent on the degree of pulmonary vascular disease.

[The role of serum osmolality monitoring in patients with severe intracranial lesion].
We dynamically determined serum osmolality in 1379 patients with severe intracranial lesion for 2843 times between January 1992 and July 1995. Using auto-control and after abandoned osmolality related interference factors we obtained the following results. Quantitative correlation analysis on the level of serum osmolality, intracranial pressure and the dose of mannitol showed that there was a negative correlation between the level of serum osmolality and intracranial pressure, while a positive correlation existed between the intracranial pressure and the dose of mannitol. ⋯ The efficious duration of mannitol, two different ways of diminishing or withdrawing the dose of mannitol, and the more safer velocity for correcting the state of hyperosmolality were also discussed. We conclude that to monitor the dynamic change of serum osmolality from time to time is of great help in lowering the incidence and mortality of hyperosmotic complications. Serum osmolality monitoring plays an important role in making fluid balance and compromizing the contradiction between dehydration and infusion as well as prevention and therapy of hyperosmotic complications, and outcome estimation as well.

[Reconstruction of right ventricular outflow tract using transannular patch in 52 children with tetralogy of Fallot].
52 children with tetralogy of Fallot received reconstruction of right ventricular outflow tract (RVOT) by using transannular patch. The indications for using transannular patch to reconstruct RVOT, patch materials, and the standard of enlargement pulmonary annulus were studied. ⋯ The autologous pericardium was the most acceptable material for patch. All patients showed no obstruction of RVOT during early and late postoperative follow-up, althought most of them had certain degree of pulmonary regurgitation (PR) in first postoperative year, whicli was gradually attenuated as their life time long-drawn, with better exertion tolerance.
