Neurocysticercosis is a brain disease due to the larval stage of the pork tapeworm (Taenia solium). The most common symptoms patient experience from infection inside the substance of the brain (parenchymal disease) are seizures and headaches. When the infection is either inside the fluid pockets inside the brain (ventricular disease) …
Genotype-Phenotype Study of Patients With Plaquenil -Induced Retinal Toxicity, With Evaluation of the ABCA4 Gene
Background Plaquenil (hydroxychloroquine) is an anti-inflammatory drug that is used to treat some autoimmune diseases such as lupus and rheumatoid arthritis. This drug can damage the retina by causing a condition called plaquenil-induced retinal toxicity, which may lead to vision loss. However, most people taking plaquenil do not develop this …
Collection of Blood and Urine Samples in Patients Receiving Radiation Therapy for Glioblastoma Multiforme
This study will collect blood and urine samples from patients undergoing radiation therapy for glioblastoma multiforme (a type of brain tumor) to investigate the effects of this treatment on blood cells and certain proteins. The information from this study may help scientists develop new tests to measure radiation exposure and …

A Longitudinal Study of Familial Hypereosinophilia (FE): Natural History and Markers of Disease Progression
Eosinophils are a type of white blood cell. Elevated eosinophil levels can damage the heart, nerves, and other organs, in the syndrome known as hypereosinophilic syndrome (HES). Some individuals have a hereditary form of HES known as familial eosinophilia (FE). More research on the causation and mechanisms of HES is …
Natural History Study of Biomarkers in Pulmonary Arterial Hypertension
Background High blood pressure in the lungs, known as pulmonary arterial hypertension (PAH), is a rare disorder. Some people have disease-associated PAH and some have PAH from an unknown cause. Researchers want to follow the natural history of all PAH patients to understand how PAH progresses in order to discover …
