The re-use of previously implanted pacemakers.

Two methods were used to sterilize pacemakers recovered for reimplantation in other patients. In a series of 50 reimplantations there was no battery or pocket complication which could be attributed to these methods. We believe that reimplantation is justified especially as the economic factors will become much more important with the new long-lasting, hermetically sealed lithium pacemakers.

Emergency pacing and subsequent permanent pacemaker implantation in a premature infant of 1770 g with a follow-up of 6 years.

We report successful emergency pacing followed by permanent pacemaker implantation due to complete block in an otherwise healthy premature infant of 1,770 g. Via the umbilical vein a temporary bipolar pacing lead was placed in the right ventricle. The lack of spontaneous improvement warranted implantation of a permanent pacemaker system at the age of 2 weeks. Via a transatrial approach an endocardial unipolar screw-in lead was placed in the right ventricle and connected to a pulse generator implanted subcutaneously. During the follow-up period of 6 years the child has been doing well with his VVI-R pacemaker operating at rates between 80 and 160 pulses/minute at a chronic stimulation threshold below 0.9 V at 0.37 msec.

Long term results and morbidity of paraaortic compared with paraaortic and iliac adjuvant radiation in clinical stage I seminoma.

BACKGROUND: Radiotherapy is accepted as standard adjuvant treatment for low-stage seminoma and results in excellent survival rates. The optimal radiation field for stage I seminoma, however, is still being discussed. PATIENTS AND METHODS: In a retrospective study we evaluated long-term results concerning survival, relapse-pattern, and acute and chronic toxicity in patients receiving adjuvant radiotherapy of the paraaortic and ipsilateral iliac lymph nodes (hockey-stick, HS) versus radiotherapy of the paraaortic lymph nodes only (PA). From 1979-1997, 129 patients (median age 32 years) in clinical stage I received adjuvant radiotherapy. Eighty-seven patients were treated with 36 Gy to the HS field and 42 patients were treated with a median of 28 Gy to the PA field. RESULTS: With a median follow-up of 7.7 years (HS) and 5.2 years (PA) the relapse rate was 3.4% and 2.4%, respectively. There was no abdominal or pelvic recurrence in either group. Radiotherapy was well tolerated in both groups. No significant difference in acute or chronic toxicity was noted. However, lower gastrointestinal tract toxicities and myelotoxicities appeared less frequent in the PA group. Second malignancies only occurred in the HS group. Overall survival in the HS and PA group was 96.6% and 100%, respectively. No patient died of seminoma. CONCLUSION: With paraaortic radiotherapy only, long-term disease-specific survival was excellent. Decreased risk of acute toxicity and of second malignancies are potential benefits of the reduced radiation field.
