[Primary sternal hemangiosarcoma].

We describe a 22-year-old man with a bone mass in the middle and lower third of the sternum with no signs of respiratory deterioration. After biopsy by incision established a diagnosis of hemangiosarcoma, appropriate resection and repair of the thoracic wall was scheduled. An adequate amount of tissue for analysis must be obtained to allow choice of a surgical technique that will assure the best prognosis in malignant tumors of the sternum and assignation of the most appropriate mechanical ventilation procedure.

Heparin cofactor II in diabetic patients.

Levels of heparin cofactor II (HCII) activity and antigen and electrophoretic pattern were studied both in normal subjects and in type I diabetic patients with high and normal levels of glycosylated haemoglobin. There was a significant reduction in HCII activity (83 +/- 7%) in patients with high levels of glycosylated haemoglobin compared with controls (95 +/- 17%; P < 0.001). However, plasma HCII antigen levels were not decreased in these patients.

The prevalence of diabetic retinopathy in northwest Spain. An epidemiological study of diabetic retinopathy in Galicia. I.

The prevalence of retinopathy was studied in a group of 1179 diabetic patients attending 11 diabetologic centres in Gallica (Northwest of Spain). The age of the patients was 61.7 +/- 13.8 years, 43.8% were males and 56.2% females. The patients had had diabetes from 8.4 +/- 7.5 years, 30.4% were being treated with insulin, and 69.6% with oral antihyperglycaemics. 16.1% were aged under 40 years at onset as against 83.9% aged over 40 years. The prevalence of retinopathy was 44.7, in the whole group. Stepwise multiple regression analysis identified treatment time since onset and age at onset as the factors affecting prevalence, which was 61.8% in the insulin-treated subgroup vs 37% among those treated with oral antihyperglycaemics (p < 0.0001). The prevalence of proliferative diabetic retinopathy was 5.8% in the whole group.
