Question: Abstract: Lymphoscintigraphy with Technetium antimony sulfur colloid (TASC) was used in four patients with malignant melanoma to identify the pattern of lymphatic drainage, allowing selective lymph node dissection. TASC is safe and predictive of lymph node drainage patterns. Using this technique allows visualization of multiple tiers of lymph nodes in 2 to 6 hours.

Question: Abstract: We observed quinidine-induced prolongation of bleeding time without thrombocytopenia in three subjects. In addition, we noticed a cumulative prolongation of bleeding time by a combination of quinidine and aspirin. We postulated that because both quinidine and aspirin inhibit epinephrine-induced platelet aggregation, a cumulative effect of the two drugs might be responsible for the hemostatic defect. In studies using normal human platelets, we confirmed a marked reduction in epinephrine-induced platelet aggregation by the combination of these two agents. To further study the potential mechanism of this cumulative effect, platelet lysates were incubated with the alpha 2-adrenoceptor antagonist tritiated yohimbine in the presence of quinidine and aspirin. On the basis of the radioligand binding data, the dissociation constant (KD) of alpha 2-adrenoceptors was observed to increase in the presence of quinidine as well as aspirin. The combination of these two agents caused a marked increase in the KD of platelet alpha 2-adrenoceptors without alteration in the number of receptor sites. These data suggest that the cumulative effects of quinidine and aspirin on platelet alpha 2-adrenoceptor KD may relate to the significant reduction in epinephrine-induced platelet aggregation. This phenomenon, coupled with other well-known effects of aspirin on the platelet release reaction and arachidonate metabolism, may lead to bleeding problems in some patients receiving this combination.

Question: Abstract: Ninety consecutive patients underwent surgery for coronary artery disease. Eighty-one (90%) did not require blood transfusion in the immediate postoperative period; nine patients received 16 units of blood, 6 of whom bled excessively; 2 were re-explored. Twelve had post-operative haemoglobins below 8.5 G/dl during their stay. They were transfused a total of 28 units of blood before discharge. Post-operative blood loss in the 9 transfused early averaged 894 +/- 176 ml (SEM). Loss from the not transfused patients averaged 481 +/- 18 ml (p less than 0.001). Patients transfused later had a mean loss of 510 +/- 36 ml (P NS). Sixty-nine patients were not transfused. Haemoglobin on the first post-operative day was 11.3 +/- 1.3 G/dl (SD). This declined to 10.2 +/- 1.2 G/dl on the fifth day. Discharge haemoglobin was 10.5 +/- 1.2 G/dl. Two patients died, one of myocardial infarction on the third day and the other of pancreatitis on the fourth. Both had had early blood transfusion. Haemoglobins were above 10 G/dl. Of the 69 untransfused patients 17% had supraventricular arrhythmias. Ten percent had serous wound discharges; 3 were infected. There were no sternal dehiscences. It is concluded that bank blood transfusion with its attendant hazards and expense is easily avoidable in most patients. This saving of resources will increase the availability of blood and rare groups for surgery.
