Visualization of malignant lymphomas and granulomatous disease is possible by [111In-DTPA-D-Phe1]octreotide scintigraphy through binding of the radioligand to somatostatin receptors on activated leukocytes. Because thyroidal and orbital tissues are infiltrated by activated leukocytes in Graves' disease, a cross-sectional study to visualize disease activity with [111In-DTPA-D-Phe1]octreotide scintigraphy was performed. A correlation between thyroidal [111In-DTPA-D-Phe1]octreotide accumulation and free T4 (disease expression) and thyroid binding-inhibiting immunoglobulins (disease activity) is present in untreated hyperthyroid Graves' disease. There is also a correlation between orbital [111In-DTPA-D-Phe1]octreotide uptake and the clinical activity score (disease activity) and total eye score (disease expression), respectively, in Graves' orbitopathy. Visualization of thyroidal and orbital Graves' disease is feasible, but further investigation is necessary to establish the role of [111In-DTPA-D-Phe1]octreotide scintigraphy in representing disease activity and expression and in predicting therapeutical outcome.

Renographic studies under standardised conditions of maximal diuresis provoked by infusion of hypotonic saline and frusemide were made on 51 patients with 54 dilated upper urinary tract systems in order to distinguish obstructed from non-obstructed systems. Of the 23 systems judged on clinical and radiological grounds to be obstructed only 12 were in fact obstructed following infusion of hypotonic saline and frusemide. In 10 of these systems (10 patients) an Anderson-Hynes pyeloplasty was carried out. All systems showed improved renal function after operation and the renographic pattern became non-obstructed.

A total of 33 women with postmenopausal osteoporosis were matched pairwise by age, years since menopause, and body mass index and randomized to receive either cyclic estrogen-progestagen replacement treatment (group 1) or the same treatment plus nandrolone decanoate (ND; group 2). Both groups were treated during 3 years and subsequently followed for another year off treatment. A year after cessation of the treatment the distal forearm bone mineral content in group 2 was significantly higher than that in group 1. Bone mass measurements in the axial skeleton already showed a significant difference in favor of group 2 after 3 years treatment, which persisted during the year off treatment. The decline in lumbar bone mineral mass and density in the 1 year off treatment was similar in both groups. Correction for body mass did not change these results. Bone turnover parameters did not show significant differences between the two groups after cessation of treatment. A higher muscle mass, induced by ND, could partly explain the differences between the groups since even 1 year after treatment was stopped an increased serum creatinine level was still observed in group 2.
