In the xenodiagnosis (XD) of American trypanosomiasis (Chagas disease), Trypanosoma cruzi in the triatomine bugs fed on the patient can now be detected using PCR (XD-PCR) as well as by microscopy (XD-M). In a study to compare XD-PCR with XD-M, triatomine bugs were fed on 50 cases of chronic American trypanosomiasis, of whom only 25 were ever found positive(More)
Background: P300 component from event-related potentials (ERPs) is considered a general index of information processing as a reliable measure of cognitive function and is related to attention and working memory operations involved during the oddball task. Reduced P300 amplitude and increased latency have been reported previously in patients with Parkinson’s(More)
A 45 year old male was admitted to the hospital for unsteady gait and dizziness. The brain CT showed bilateral cerebellar ischemic stroke. The MRI corroborated the stroke in the cerebellum with a third acute ischemic stroke in the pons. The laboratory work up showed a positive anti beta2-glycoprotein I antibodies. The cerebral angiogram showed the(More)
BACKGROUND Ablative procedures are still frequent for the surgical treatment of Parkinson's disease (PD). Although the P300 component has been used to assess cognitive changes induced by levodopa and deep brain stimulation (DBS), the effects caused by unilateral pallidotomy remain unknown. MATERIAL AND METHODS P300 amplitude and latency in 10 PD patients(More)
