Evaluation of dominant thyroid masses.

Controversy exists concerning the management of solitary thryoid nodules because of conflicting information converning the high clinical incidence of thyroid nodules, the varying incidence of cancer reported in those surgically excised and the infrequency of death from thyroid cancer. During the past several years, a plan for evaluating patients with dominant thyroid masses has evolved. The objective is to avoid unnecessary operations by identifying patients with a high risk of cancer. The criteria which are used are the age and sex of the patient, the duration of the mass, 125I or 99mTc scans, 75Selenomethionine scans, B-mode ultrasonography and the response of the mass to suppressive therapy. This is a report of the findings in 222 patients who have been studied employing this approach. Thirty per cent of the patients were operated upon. Forty per cent had neoplasms (well differentiated cancer--28.8%, adenoma--12.1%), 47.0%--nodular goiter, 6.1% cysts, and 6.1% chronic thyroiditis. The incidence of cancer in the 222 patients was 8.6% and adenoma 3.6%. Patients at greatest risk of having cancer are those with solid nonfunctioning nodules which fail to regress with suppressive therapy. This study indicates that the approach described above is effective in selecting for surgical excision those individuals at greatest risk of having thyroid cancer.

Pressure dressings and postarteriographic care of the femoral puncture site.

Patient dissatisfaction with prolonged bed rest and the discomfort caused by pressure dressings led to the following evaluation. Alternate application of pressure dressings and band-aids to femoral artery puncture sites was performed in 754 arteriographic examinations. The application of pressure dressings for 16-24 hours, especially in hypertensive patients, was found to be justified by a significant reduction in delayed bleeding requiring further medical attention. A minimum application time of 8 hours is supported because all instances of delayed bleeding occurred within 8 hours of the procedure. Arterial thrombosis is not affected by the use of pressure dressings. The rationale for recommendation of bed rest is largely anecdotal and is supported by almost all experienced angiographers responding to our questionnaire.

Gallium citrate Ga 67 scans in febrile patients.

Scanning with gallium citrate Ga 67 is a sensitive technique for the detection of localized inflammatory disease. In a group of 22 febrile patients, 17 had one or more abnormal areas of radioactive gallium localization. Eight patients showed localized areas of inflammation; five showed no area of local inflammation within the field of the scan. The remaining patients had excellent clinical and laboratory confirmation of neoplastic or inflammatory disease. These cases illustrate the usefulness of radioactive gallium in febrile patients in whom the cause of the fever cannot be otherwise determined.

Liver imaging in the diagnosis of hepatic venous thrombosis in paroxysmal nocturnal hemoglobinuria.

Eleven patients with paroxysmal nocturnal hemoglobinuria were studied by serial liver imaging. This disease has a generalized thrombotic tendency, and progressive diffuse hepatic venous thrombosis has been emphasized in recent studies. Radionuclide imaging proved to be of great help in establishing the diagnosis of hepatic venous thrombosis and following the progress of the disease process. Abnormal patterns in hepatic venous occlusion include (a) enlargement of the liver (especially the right lobe), (b) extrahepatic localization of radionuclide, and (c) areas of decreased uptake in the distribution of the involved veins. These findings develop rapidly and are very characteristic in the clinical setting.

Imaging studies in renal failure. Emphasis of selection and sequencing in the clinical evaluation.

The focus of this review will be on the current role of imaging studies in the clinical evaluation of patients with acute and chronic renal failure. We will stress the application of these studies in specific clinical settings in an effort to indicate the current value, and also to suggest fruitful areas for future clinical investigation. It is clear that imaging studies are an essential component in the evaluation of acute and chronic renal failure. Physicians who manage such patients must choose appropriately from a variety of available studies to obtain a maximal information with the least risk to their patients. This selection is influenced by local conditions, the most important among these being the experience and technical skill of those involved. Attention to detail is particularly important and it is critical that the studies be done at the appropriate time in the evaluation. There will be emphasis on the evolving role of imaging studies in evaluating these patients.
