OBJECTIVES Over the past few years many reports have shown that posteroventral pallidotomy is an effective method for treating advanced cases of Parkinson's disease. The main differences with earlier descriptions were the use of standardised evaluation with new high resolution MRI studies and of single cell microrecording which can electrophysiologically define the sensorimotor portion of the i...

BACKGROUND The ventricular septal defect (VSD) is the most common form of congenital heart defects. The purpose of this study was to evaluate the results of the early complications and mid-term follow-up of the transcatheter closure of the VSD using the Amplatzer VSD Occluder. METHODS Between April 2012 and October 2013, 110 patients underwent the percutaneous closure of the perimembranous VS...

that had started following an argument. She did not have cardiologic symptoms, except for an ECG with negative T-waves in the lateral aspect and troponin T concentration of 0.06 in the laboratory workup (peak, 0.23). An emergency echocardiogram showed apical akinesia with preserved ejection fraction (Figure). Urgent coronary angiography performed 2 hours later showed a mild lesion in the right ...

THE value of rontgenography in the diagnosis and localization of intracranial tumors is mainly restricted to the cases in which the neoplasm has affected the skull. In an analysis of the X-ray findings in one hundred cases of /brain tumor from Doctor Halsted's Clinic, Heuer and I 1 have shown that in only 6 per cent. of the cases did the tumor cast a shadow, and in these it was only the calcifi...

Thirty two children (aged 5-19 years) with no clinical evidence of significant cardiovascular disease undertook continuous staged supine exercise on a bicycle ergometer. Multigated radionuclide ventriculography was performed at rest and during each exercise stage. Exercise duration and total workload both increased with age. Aerobic work correlated better with age than did total work. In most c...

BACKGROUND Ritter's method is a tool used to optimize AV delay in DDD pacemaker patients with normal left ventricular function only. The goal of our study was to evaluate Ritter's method in AV delay-interval optimization in patients with reduced left ventricular function. METHODS Patients with implanted DDD pacemakers and AVB III degrees were assigned to one of two groups according to ejectio...

Gold 195m (Au-195m) has a half-life of 30.5 sec and can be produced at the bedside from the parent mercury-195m (T 1/2 = 41.6 hr). The generator produced sterile pyrogen-free Au-195m with mercury breakthrough of 0.75 +/- 0.09 (s.e.m.) muCi per mCi of Au-195m. Approximately 20 to 25 mCi of Au-195m was produced per elution from a generator containing 155 mCi of Hg-195m. We compared first-pass res...
