Five hundred eighty-six consecutive frozen-section consultations performed during a 1-year period were studied prospectively in order to assess the accuracy of the method and develop a quality control mechanism. The overall accuracy was 97.1%. The accuracy of the method with breast lesions was 97.9%. Specimens from the gastrointestinal tract and thyroid(More)
An investigation of the long-term effects of childhood scalp irradiation demonstrated a significantly increased risk of thyroid tumors in the irradiated population. Because of the complexity of thyroid cancer diagnosis, a histopathologic slide review of 59 of the 68 patients (irradiated and nonirradiated) with thyroid disease was undertaken. The review(More)
The present study continues our investigation of the bladder antimicrobial mechanisms following bacterial infection. Since the process of spontaneous clearance of bacteria (E. coli) from the mouse bladder is greatly accelerated upon re-infection, a histopathological comparison was made of initially infected (II) versus re-infected (RI) mice. It was(More)
A 17-year-old girl with refractory, but nonmalignant, hypertension and hypokalemia is presented. A state of primary hyperreninism and secondary hyperaldosteronism was found to exist, together with a renin-producing Sertoli cell ovarian tumor. Upon removal of the tumor, this patient attained both a normotensive and a normokalemic state. A brief review is(More)
A 56-year-old man had fever, precordial pain, and a mediastinal mass. The mass disappeared two months later and the patient remained asymptomatic for 2 1/2 years. At that time a full-blown nephrotic syndrome developed, with minimal-change glomerulopathy. The chest x-ray film showed the reappearance of a giant mediastinal mass. On biopsy of the mass,(More)
Coronary artery disease (CAD) is the leading cause of death in the United States. Although progression of CAD can be controlled using drugs and diet, it is usually detected in advanced stages when invasive treatment is required. Current methods to detect CAD are invasive and/or costly, hence not suitable as a regular screening tool to detect CAD in early(More)
A patient with intestinal amyloidosis with perforation was successfully treated by resection of almost the whole involved small intestine and is recuperating on hyperalimentation therapy. Because there were no signs of amyloiditic deposition in other parts of the body and no other cause of the amyloidosis, the case was considered to be selective localized(More)
