[Clinico-laboratory, immunologic and radionuclide joint indices in psoriatic arthropathy].

A juxtaposition between the clinical-laboratory, immunologic and radionucleotide articular parameters was performed in 50 patients with psoriatic arthropathy, distributed according to the incidence of X-ray manifestations. The late and moderate changes in ESK, leukocytes, fibrinogen, DPA and phosphatasemia do not characterize the severity of the disease. A tendency to hyperuricemia and hypercalcemia is established in the period of arthralgia before the X-ray image for bone-tissue damage.

[Scintigraphic study of the kidneys with a 99m Tc-ascorbic complex in chronic pyelonephritis patients].

A scintigraphic study of the kidneys was carried out in 1780 patients with chronic pyelonephritis: 1308 with calculous and 472 with acalculous pyelonephritis. The scintigraphic finding was interpreted for each kidney separately. Diffuse damages of renal parenchyma was most often observed (47,6%), being, in the majority of the cases--bilateral.

[Comparative clinical x-ray, radioisotope nephrographic and ultrasonic studies of chronic pyelonephritis patients].

The authors compare the incidence of the changes established by X-ray, radioisotope-nephrographic and ultrasound studies on 115 patients with chronic pyelonephritis. Most frequent and most characteristic are the changes with venous urography. Though not specific, the changes in the isotope-nephrogram and ultrasound contribute to the establishment of functional and structural disturbances in chronic pyelonephritis.

[Comparison of x-ray and radionuclide studies of the joints in patients with Touraine-Solente-Golé syndrome].

The thesis of primariness of the disease and of its osseous tissue manifestations is discussed on the grounds of the results from a complex study on 3 patients. The periosteal ossifying hyperplasia and disturbances in the osseous tissue structure develop with no other organ symptomatics and in the absence of any changes in the available laboratory and immunological indices. The macromorphological X-ray characteristic corresponds to the radionuclide tests of the study with 99MTc-pertechnetate, 99MTc-pyrophosphate and 99MTc-sulfocolloid, informing about abnormal vascularization index, growth of bone-marrow tissue and intensified joint-tissue anabolism.

[Relation between serum enzymes and articular radionuclide tests in the diagnosis of osteoarthrosis and rheumatoid arthritis].

Serum enzymes and articular radionuclide tests have a restricted application in solving the current diagnostic and differential-diagnostic problems of present-day rheumatology. The enzyme tests became positive in case of a high activity of rheumatoid arthritis, not objectivizing the articular degeneration. Their correlation with radionuclide tests of the patients with osteoarthrosis and the patients with rheumatoid arthritis is not elucidated.

[Diagnosis of rheumatoid arthritis by a complex radionuclide study of the joints].

The knee joints of 88 patients with rheumatoid arthritis and 22 healthy subjects were examined via a complex radiometric method. The time for half-elimination of 133xenon, injected into the joints, is 154.8 minutes for the control group and 118.

[Potentials of complex radionuclide study of the joints in the diagnosis of osteoarthrosis].

The possibilities of the complex radionucleid joint investigations in the diagnosis of ostheoarthrosis are discussed. The investigation covered 104 patients with osteoarthrosis, aged 471 +/- 2.0 and 22 control subjects, aged 43.

[Scintigraphic study of the sacroiliac joints].

Scintigraphic and radiometric investigation with 99mTc-pyrophosphate was carried out on the sacro-iliac joints of 79 patients: 48 with positive form of Behterev disease, 26 -- with probable form of the disease, 2 -- with Reiter syndrome and 2 -- with rheumatoid arthritis. Scintigraphy was combined with radiometric investigation (determination of sacro-iliac -- sacral index) with a view to obtaining quantitative information about the degree of accumulation of pyrophosphate in sacro-iliac joints. The data from the scintigraphic and radiometric investigations were juxaposed to clinical laboratory and X-ray investigations.
