Failure to inhibit irrelevant information in non-clinical schizotypal individuals.

The present study compared negative priming performance in a non-clinical sample of individuals based on their schizotypal personality scale (STA) scores. There were 13 High STA and 19 Low STA individuals. High, but not Low, STA individuals displayed deficient negative priming, replicating previous findings.

Implicit memory of nonclinical schizotypal individuals.

In the present study a form of implicit memory performance was examined by employing the serial reaction-time paradigm with a nonclinical sample of 22 hypothetically schizotypal college students and 22 nonschizotypal college students. The formation of new associations was tested; analysis showed no difference between these two groups on this measure of implicit memory.

Diagnosis of recurrent hyperparathyroidism: comparison of MR imaging and other imaging techniques.

Several reports have indicated good results with MR imaging of hyperparathyroidism. However, its use in recurrent hyperparathyroidism has not been assessed separately. Thirty patients with recurrent hyperparathyroidism were evaluated by MR with both T1- and T2-weighted images.

Gallium uptake in the thyroid gland in amiodarone-induced hyperthyroidism.

Amiodarone is an iodinated antiarrhythmic agent that is effective in the treatment of atrial and ventricular arrhythmias. A number of side effects are seen, including pulmonary toxicity and thyroid dysfunction. A patient with both amiodarone-induced pneumonitis and hyperthyroidism who exhibited abnormal gallium activity in the lungs, as well as diffuse gallium uptake in the thyroid gland is presented.

Localizing studies in patients with persistent or recurrent hyperparathyroidism.

Preoperative localizing studies are essential for patients with persistent or recurrent hyperparathyroidism requiring reoperation, because of loss of normal tissue planes and because the hyperfunctioning parathyroid tissue that remains is more likely to be situated in an ectopic position. The value of noninvasive and invasive localizing techniques was evaluated in 59 consecutive patients undergoing reoperation for persistent (40 patients) or recurrent (19 patients) hyperparathyroidism. Magnetic resonance imaging was performed in 17 patients; 11 results (65%) were positive, 3 (18%) were negative, and 3 (18%) were false-positive.
