Successful localisation of parathyroid adenomata by thallium-201 and technetium-99m subtraction scintigraphy: description of an improved technique.

An improved method for parathyroid scanning using thallium-201 and technetium-99m subtraction imaging is described. The technique successfully localised ten of eleven parathyroid adenomas confirmed at neck exploration. Two false-positive studies were encountered in patients with no adenoma at operation, probably due to thyroid nodules. The technique was less successful in identifying diffusely hyperplastic parathyroid glands and was negative in a single patient with recurrent, functional parathyroid carcinoma.

HLA antigens in a Scottish psoriatic population.

Sixty-one patients in the Dundee area suffering from psoriasis were typed for HLA-A and HLA-B antigens. On the basis of the typing results, the patients were divided into three groups, and studied with respect to sex, age of onset and familial incidence of the disease. The frequency of HLA-A1 appeared to be increased and HLA-B7 decreased but HLA-B13 and HLA-B17 were highly significantly increased (P less than 10(-6) and P less than 10(-10) respectively) in the psoriatic group compared to 204 controls. Of particular interest was a highly significant association of HLA-A1 with HLA-B17 in psoriatic patients. Family studies showed HLA-B17 to be a useful genetic marker for psoriasis in the families of B17 positive patients. Considerations of age of onset, familial incidence and typing data suggest that there is heterogeneity of genetic susceptibility to psoriasis and that one probable mechanism is the dominant inheritance of a "disease allele" in linkage disequilibrium with the allele coding for HLA-B17.
