HIV-1 viral encephalitis produced by antiretroviral-resistant strains in cerebrospinal fluid (CSF), despite suppression of plasma HIV-1 RNA, has been rarely described. We report two cases of symptomatic viral encephalitis demonstrated by clinical, magnetic resonance imaging (MRI), and an inflammatory CSF profile. Viral load in CSF was 24,000 and 6850(More)
BACKGROUND Stroke risk is increased in AIDS patients, and highly active antiretroviral therapy (HAART) may accelerate atherosclerosis, but little is known about the incidence and risk factors for ischemic stroke in patients under HAART. We have studied the incidence, types of stroke and possible risk factors for cerebrovascular ischemic events in a large(More)
OBJECTIVES Hyperechogenicity of the substantia nigra on transcranial sonography is used for diagnosing Parkinson disease (PD). Cutoff values for the substantia nigra echogenic area, defining substantia nigra hyperechogenicity, vary among ultrasound systems from different manufacturers. In this study we wanted to determine the cutoff criterion for a Toshiba(More)
BACKGROUND AND PURPOSE Progressive multifocal leucoencephalopathy-associated immune reconstitution inflammatory syndrome (PML-IRIS) is the paradoxical worsening or unmasking of preexisting infection with JC virus attributable to a rapid recovery of the immune system after highly active antiretroviral therapy (HAART) initiation. We investigated the incidence(More)
We used a multiplex nested-PCR assay for the simultaneous detection in cerebrospinal fluid (CSF) of five human herpesviruses (HVs) (cytomegalovirus [CMV], Epstein-Barr virus [EBV], varicella-zoster virus [VZV], herpes simplex virus [HSV], and human herpesvirus 6 [HHV-6]) in a clinical evaluation of human immunodeficiency virus (HIV)-infected patients with(More)
STUDY DESIGN A report of a patient with cervical intramedullary cysticercosis is presented. OBJECTIVES To report the first case of intramedullary. cysticercosis cured with drug management only, which supports the hypothesis that management with anthelmintics might be successfully used in this form of cysticercosis. SUMMARY OF BACKGROUND DATA(More)
Adenosine deaminase activity (ADA) determination in cerebrospinal fluid (CSF) is considered a specific test for the diagnosis of tuberculous meningitis. In order to study the variability of this marker in patients with different neurological disorders associated with HIV infection, and its utility for the diagnosis of tuberculous meningitis in these(More)
We studied 17 consecutive cases of acute polyradiculopathy (PR) diagnosed in HIV-infected patients to investigate the possible causes of this syndrome in our milieu. Sixteen patients presented with lumbosacral PR and one patient had predominantly cervical PR. Electrophysiological study showed a predominantly motor axonal neuropathy in all patients examined.(More)
Neurological complications (NCs) are a major cause of morbidity and mortality in patients with infectious endocarditis (IE). The frequency of these complications has been found to remain constant since the preantibiotic era despite profound epidemiological changes and therapeutic advances. We have reviewed retrospectively all the cases of IE attended at a(More)
