The quality and quantity of interpersonal relations were investigated by a special questionnaire to discover the connexion of psychonervous disorders with the contact behaviour. The psychonervous disorder was measured by a screening method, which examines the neurotic status. 361 patients of an urban population were asked by the questionnaire. 309 questionnaires of the probably neurotic patients and non neurotic patients were analyzed with respect to the differences between the two groups patients. Probably neurotic patients felt more stressed. They are more directed to the family members. The contact behaviour of the probably neurotic patients is more restrained in profession and also in free time than the behaviour of the non neurotic patients. The fewer agreement between reality and desire of the contact behaviour is typical for the probably neurotic patients. The intention of the conclusions was to help them to develop a feeling of interpersonal contentment.

Radiation dose assessment in radioiodine therapy. 2. Practical implementation using quantitative scanning and PET, with initial results on thyroid carcinoma.

We have designed special high-resolution, low-sensitivity collimators for a dual-headed whole-body scanner for imaging and quantifying therapy levels of iodine-131. In addition, we have used positron emission tomography (PET) with a low-cost large-area PET camera to achieve improved accuracy in the estimate to tumor mass. The physical performance of these two imaging systems is described. In order to illustrate the practical implementation of these systems for the assessment of radiation dose to normal and tumour tissue during radioiodine therapy, three clinical examples are reported, and a summary of the initial clinical results obtained from 16 patients with carcinoma of the thyroid is presented. The dose to normal thyroid remnants for patients undergoing ablation ranged from 16 to 400 Gy, while the dose to involved neck nodes ranged from 2.5 to 33 Gy for patients undergoing post-ablation radioiodine therapy. In one patient with distant metastasis in the spine, a dose of 100 Gy was achieved. The techniques described in this paper can be used to determine if sufficient activity can be accumulated in tumours to provide a therapeutic effect while minimising irradiation of normal tissues by avoiding administrations which do not provide tumouricidal radiation doses.

Radiation dosage during AO locking femoral nailing.

Radiation dosages to both the patient and the surgeon were measured during 10 consecutive AO locking nail procedures. The total screening time for each procedure averaged 12 min 8 s; the average screening time for distal locking was 6 min 52 s. Radiation dosages to surgeons' hands, thyroid and gonads and to the patients were well within permitted safety levels.
