BACKGROUND Similar to the model for Sydenham's chorea, antineuronal antibodies, which develop in response to a preceding streptococcal infection, have been speculated to have a role in the development of Tourette syndrome (TS). METHODS Serum antibodies against human caudate, putamen, and globus pallidus (interna and externa) were assayed by enzyme-linked(More)
A 34 year old man presented with acute chest pain. His ECG was very abnormal but stable and he was treated with opiate analgesia. When his condition did not improve, chest radiography and cardiac ultrasound were performed. Both revealed metal dense deposits in the heart. On questioning, the patient revealed that he had self injected with mercury 15 years(More)
We report a 7-year-old boy who presented with two-month history of worsening low back and right leg pain. Conventional MR images demonstrated a poorly outlined intradural mass recognized by the displacement of the conus medullaris and the nerve roots of the cauda equina at the L2–3 level. The signal intensity of the lesion was similar to CSF. There was no(More)
A 28-year-old woman with a mechanical aortic heart valve experienced an embolic stroke in early pregnancy after her anticoagulation therapy was changed from warfarin to heparin. This occurred despite use of a subcutaneous heparin infusion pump and optimal anticoagulation. Thromboembolism can occur in pregnant patients with mechanical heart valves despite(More)
BACKGROUND Similar to the model for Sydenham's chorea, antineuronal antibodies (ANAb), which develop in response to a preceding streptococcal infection, have been speculated to have a role in the development of Tourette syndrome (TS). METHODS Serum antibodies against the neuron-like HTB-10 neuroblastoma cell were assayed by ELISA methods and Western blot(More)
Coronary artery spasm is a well-documented phenomenon in patients undergoing medial treatment. We describe coronary artery spasm occurring in the immediate postoperative period following coronary artery bypass operation. The spasm occurred in a vessel that was not operated on and that had no apparent lesion. The diagnosis of spasm was made by coronary(More)
Cardiac muscle death caused by coronary artery occlusion is a dynamic process that often takes hours or days. Emergency revascularization (saphenous vein bypass graft (SVBG) during acute myocardial infarction (MI) can interrupt myocardial necrosis, salvage ischemic myocardium and revascularize vessels with obstructive lesions not involved in the MI. In this(More)
Remote ischemic preconditioning (RIPC; repeated short reversible periods of ischemia) protects the heart against subsequent ischemic injury. We explored whether RIPC can attenuate post-exercise changes in cardiac troponin T (cTnT) and cardiac function in healthy individuals. In a randomized, crossover design, 14 participants completed 1-h cycling time(More)
Tourette's syndrome (TS) is a complex neurobehavioral disorder emerging in childhood and is characterized by motor and vocal tics of at least one year in duration. In a portion of patients with TS, environmental (non-genetic) factors may either have an etiologic role or act to modulate the phenotype. One possible environmental factor may be antibodies to(More)
OBJECTIVE To examine the additive effect of t'ai chi (TC) to diet education on the traditional coronary heart disease (CHD) risk factor low-density lipoprotein cholesterol (LDL-C) and on emerging CHD risk factors (apolipoprotein B and LDL particle size) in older obese women. DESIGN Ancillary study of a randomized clinical trial. SETTING University of(More)
