[EX Q]: Abstract: Forty-two patients with intransit metastases of melanoma in a limb were treated by isolated regional perfusion chemotherapy using mechlorethamine (nitrogen mustard). Group 1 (n = 12) underwent treatment at low dose, less than 0.35 mg/kg, or low temperature, less than 38 degrees C. Group 2 (n = 30) received higher doses, 0.35 to 0.6 mg/kg, plus heat at 38 degrees C to 41 degrees C. No patient had evidence of disease outside the limb at the time of perfusion. The median follow-up time was 48 months (range, 1 to 9 years). Of the 42 patients, 29 had measurable lesions that responded as follows: group 1, complete response (CR) in two of ten and partial response (PR) in none; group 2, CR in six of 19 and PR in six of 19. The combined CR and PR rate of 12 of 19 in group 2 was significantly higher than that of group 1 (P less than .05). CR lasted only 2 months in the two patients of group 1, but persisted in the six patients of Group 2, four of whom are still alive free of disease at 16, 21, 33, and 40 months. Relapse-free control of disease in the limb was achieved in 36% of the patients in group 2 at 24 months, compared with 0% in group 1 (P less than .05). An overall survival of 74% at 48 months was observed in group 2, significantly higher than that of 64% for group 1 (P less than .05). The status of the regional lymph nodes (RLN) and the number of metastases did not affect tumor response. However, 77% of RLN-negative patients survived 48 months, in contrast to only 38% of RLN-positive patients (P less than .05). One patient died postoperatively of myocardial infarction. No serious systemic toxicity developed. Two patients who underwent repeat salvage perfusions developed a reversible peripheral neuropathy in the limb. Limb function was good after treatment, and dramatically improved in patients who had advanced satellitosis that responded to treatment. These results suggest that heated limb perfusion using mechlorethamine at an adequate dose can offer long-term control of intransit metastases in approximately one third of these patients, with preservation of good limb function and possible prolongation of survival.

[EX Q]: Abstract: The objective of this study was to find naturally occurring anti-idiotypic (anti-Id) antibodies to anti-human thyroglobulin (anti-hTg) idiotype in sera of patients with autoimmune thyroid disease. Sera from patients with Hashimoto's thyroiditis (HT), Graves' disease (GD), rheumatoid arthritis (RA), and systemic lupus erythematosus (SLE) and sera from normal subjects were tested for the presence of anti-Id antibodies against mouse anti-hTg monoclonal antibodies (McAb) in indirect ELISA and in indirect solid-phase RIA. Microtitration plates were coated with six McAb, five of them directed against different epitopes on hTg molecule, and then incubated with patients' sera. The bound antibody was detected with either peroxidase or 125I-labeled anti-human IgG. The specific positive reaction was observed in four of 40 patients with HT, in two of 26 patients with GD, in seven of 58 patients with RA, and in none of 20 normal subjects. The detected binding was due to the presence of anti-hTg anti-Id antibodies and not to Tg-anti-Tg circulating immune complexes, as the positive sera did not contain hTg when resolved on SDS-PAGE, nor did they bind to all anti-hTg McAb tested. The binding was dose dependent, and titers of anti-Id antibodies varied from 1:243 to 1:2187. The binding could be inhibited up to 50% by hTg, but not by the thyroid microsomal antigen, indicating that some of those anti-Id might represent the internal image of the antigen. Serum from the patient 3403, showing the strongest reactivity against McAb A-3, was chosen for IgG purification and F(ab')2 fragment isolation. The 3403 F(ab')2 fragment, but not the Fc fragment, was found to react specifically with four mouse anti-hTg McAb but not with the control mouse IgG. Thus, the obtained results permit the conclusion that anti-hTg anti-Id antibodies could occur naturally during the course of thyroid autoimmune disorders.

[EX Q]: Abstract: Fast arm movements involving the shoulder and elbow joints have been analysed in normal controls and in patients with Parkinson's disease. The subjects were requested to draw on a graphic tablet triangles and squares of different size and shape. The patients produced a larger number of EMG burst compared with controls. The movements were accurate, and each segment of the geometric figures was performed with a roughly straight trajectory, but the time necessary to trace the geometric figures and the pauses at the vertices were prolonged. We conclude that in Parkinson's disease the disability in generating two joint ballistic movements depends on a difficulty in running motor programmes for complex trajectories.
