AIM: The cumulative index, the recovery, the onset and the duration of action, of atracurium, cisatracurium, vecuronium and rocuronium in uremic patients undergoing kidney transplantation compared to healthy patients undergoing general surgery were studied. METHODS: In all patients (64 uremic vs 62 "healthy" patients) after anesthesia induction, atracurium 0.5 mgxkg(-1) or cisatracurium 0.15 mgxkg(-1) or vecuronium 0.1 mgxkg(-1) or rocuronium 0.6 mgxkg(-1) were administered, and at the end of surgery when T1 reached 25% neostigmine 0.05 mgxkg(-1) was given. Neuro-muscu-lar transmission was monitored by accelerometry (TOF-GUARD, Organon). RESULTS: Cumulative index of vecuronium (1.3+/-0.1 vs 1.06+/-0.11, p<0.001) and rocuronium (1.45+/-0.18 vs 1.04+/-0.16, p<0.001), recovery index (time of T1 25-75) of atracurium (14.2+/-5 vs 9+/-4, p<0.005), cisatracurium (18.7+/-3 vs 9.1, p<0.001), vecuronium (18.5+/-3 vs 12.5+/-3, p<0.001) and rocuronium (18+/-6 vs 11+/-4, p<0.001) and interval T1 25% to TOF 0.8 of cisatracurium (20.5+/-1.2 vs 16+/-2.1, p<0.001) and vecuronium (27+/-6.3 vs 20+/-3.3, p<0.001) were longer in uremic patients. The onset time and the duration of action of atracurium, cisatracurium, vecuronium and rocuronium were similar in all groups compared to controls one. CONCLUSION: In patients with renal failure the use of atracurium, cisatracurium, vecuronium and rocuronium is suitable and predictable in terms of onset, and duration of action. Care has to be taken to vecuronium and rocuronium cumulative index. Neuromuscular trasmission has to be always monitored.

[Quadrantectomy and tumorectomy followed by radiotherapy in early tumors of the breast].

The authors examined 235 patients with early breast cancer treated by radiotherapy after conservative surgery during a 10-year period (1974-1984). Disease-free survival and incidence of local recurrences, in agreement with the data reported in literature, did not differ from those of patients with early breast cancer treated with radical surgery. As for local recurrences in the breast only (7/235), a slightly significant difference was observed in favor of quadrantectomy (3/62 for tumorectomy versus 4/173 for quadrantectomy). On the contrary, a significant difference was observed in the breast recurrence rate of premenopausal (5/7) and postmenopausal women (2/7). Complications occurred in 7.2% of the cases. Satisfactory esthetic results were generally obtained, with 78% good and excellent results. Doses greater than 50 Gy to the whole breast and irradiation of the axilla both worsened the esthetic results and increased complication rate. Chemotherapy does not worsen the esthetic results, while that is often the case when the removed volume is excessive in comparison to the whole breast volume.

Theoretical study for use of Leksell's stereotactic frame in radiosurgery.

The authors examine all the problems connected with the use of Leksell's frame. These problems were studied specifically for the treatment of artero-venous malformation of the brain using small fields and movement therapy of a 10 MV linear accelerator. The technique allows the administration of high radiation doses (25-30) Gy into a very small target within a fraction. In this way the surrounding tissue receives a low dose. The treatment was initially simulated with a dummy. The dosimetry gives an accuracy of +/- 1.5%. This study has been able to resolve all the theoretical and practical problems demonstrating the feasibility of the project which has already been put into effect.
