    Notes: The Strecker stent is a balloon-mounted flexible endoprothesis of knitted tantalum wires, successfully used in peripheral arteries. In our practice stents are only implanted as a bailout device after percutaneous transluminal coronary angioplasty (PTCA). In 112/5,000 consecutive patients (2.2%), a dissection could not be sealed with prolonged balloon inflations and resulted in total (28%) or subtotal occlusion. A total of 127 stents (71 Schatz–Palmaz, 56 Strecker) had to be implanted. All patients were pretreated with aspirin p.o. and 20,000 U heparin IV. Before stent implantation, they received 500 mg intracoronary aspirin, 5,000 U heparin, and 500 mL Dextrane; and after implant, between 1,500 and 2,300 U/hour heparin IV overlapping a 3-month treatment with Coumadin, aspirin p.o., and Pyridamol. Results of Strecker (n = 48) versus Schatz-Palmaz (n = 64) stent: technical success (97% vs 95%); acute thrombosis (13% vs 16%); subacute thrombosis (8% vs 16%); severe bleeding (15% vs 9%); myocardial infarction (2% vs 3%); emergency CABG (6% vs 5%); in-hospital death (10% vs 6%); restenosis (42% vs 31%); and late death (6–12 months) (6% vs 3%). Conclusion: (1) The Strecker coronary stent can be easily placed even in acute takeoff and tortuous vessels. (2) In bailout situations a high incidence of early thrombotic occlusions sets limits to both stents. (3) We, therefore, recommend urgent bypass operation after stent placement in these patients when the area at risk is large.

    Notes: Abstract Fifty children with head injury were evaluated in an attempt to estabilish a correlation between post-traumatic hyperglycaemia and long-term outcome. In all the patients, the blood glucose level was measured on admission and on the days following the trauma (threshold of normal value set at 150 mg/dl). Hyperglycaemia was seen more frequently in children with severe head injury than in those with mild and moderate head injury. It was present in 87.5% of the patients with a Glasgow Coma Score (GCS) ≤8 (the average blood glucose level on admission was 237.8±92 mg/dl), in 60% of the patients with a GCS of 9–12 (178±78.7 mg/dl) and only in 25% of those with a GCS of 13–15 (131.5±39 mg/dl). A close correlation was also seen between the outcome and the blood glucose level. In fact, the blood glucose on admission was higher in the patients with a poor outcome, i.e. in those having a Glasgow Outcome Score (GOS) of 2 or 3 and in those who died (GOS 1), than in the patients with a good outcome (GOS of 4 or 5). Finally, hyperglycaemia persisted beyond the first 24 h after trauma in all the children who died or who survived with a poor outcome. Hyperglycaemia, and especially its persistence over time, appears to be an important negative prognostic factor in children with head injury.

    Notes: Summary In the progenies of the crosses between disomics and trisomies, two plants were isolated which carried an extra chromosome that was unlike any in the standard complement. The plants were not alike; while one carried a metacentric, the other had a telocentric extra chromosome. Their detailed structure and possible modes of origin are discussed.
