In a case of potential exposure to toxic chemicals, it is often difficult to dissect the genetic, physiological, and environmental factors that contribute to illness. A recently published paper (Haley et al. 1999) raises the possibility of a link between detoxication enzyme genotype/ phenotype and the risk of illness in Gulf War veterans. This work builds on a body of interesting data regarding...

Introduction The assessment of the patient with acute impairment of consciousness requires an organized, systematic approach, beginning with the history (the diagnosis is suspected on the history alone in over 85% of cases), the physical examination, and basic laboratory testing. It is only after these steps that well-chosen neuroimaging is performed, always with a specific question in mind. Th...

Patients with Legionnaires pneumonia frequently present with neurologic abnormalities but normal neuroimaging findings. We present a case of a healthy 52-year-old man presenting with severe Legionella pneumonia and a unique constellation of focal neurologic deficits including bowel and bladder incontinence, hemiparesis, and ataxia with progression to somnolence. A transient lesion was identifie...

We present two patients who had acute paraplegia with sensory loss due to spontaneous spinal epidural hematoma (SSEH). One had myocardial infraction and the other had deep vein thrombosis, and the former was treated with anticoagulants and the latter was treated with thrombolytic agent. We analyzed the neurological status of our two cases each between its preoperative and postoperative state. P...

amyloidosis of the upper aerodigestive tract is rare in the pediatric age group. we present two cases of pediatric laryngeal amyloidosis. both of them had hoarseness as the presenting symptom. diagnostic evaluation included flexible nasopharyngoscopy, rigid laryngoscopy, biopsy, computed tomography scan and laboratory tests. the results of congo red staining of the specimen were characteristic ...

Intracranial arachnoid cysts are congenital lesions that are frequently detected incidentally. About 30% of patients have a symptomatic epileptic seizure as the presenting symptom, occasionally with other focal neurologic signs. A case is presented of a young male patient with medically refractory temporal lobe epilepsy. Following his neurological examination, epileptic zone was defined in the ...

We evaluate the results of stenting and angioplasty on carotid bifurcation stenotic lesions using protection systems, emphasizing the indications and technical aspects. Seventy-nine patients, mean age 64.5 years were treated from February,1998 to March, 2003. All patients were included in NASCET study criteria. Forty three patients were treated without the protection systems and thirty six were...

Relapses, exacerbations, and attacks are synonymous for new or worsened neurologic symptoms that are the hallmark of relapsing-remitting multiple sclerosis. Management of relapses is not always straightforward. The clinician must distinguish between true relapses, symptom fluctuation, and pseudo-relapses. Risks and benefits of treating a relapse must be considered. Once the decision to treat is...
