Filter by:The primary objective of this study is to determine whether intramuscular injections of botulinum toxin type A (Botox®) in selected cervical muscles at antidystonic dosages can reduce levodopa-induced peak-dose dyskinesias (LID) in the cervical region in adult patients with idiopathic Parkinson's disease. It is hypothesized that the intramuscular injection of antidystonic doses of botulinum toxin into cervical muscles will decrease the duration and severity of LID in the cervical region in patients with Parkinson's disease (PD).
A short term post-market monitoring of serum prolactin level change among patients with schizophrenia shifting from other antispychotics to different dosages of aripiprazole.
The ultimate goal of this proposal is to reduce dyskinesia in Parkinson's Disease (PD) patients. Dyskinesias are abnormal movements, often caused by the standard treatment for PD symptoms, levodopa. In this study, we will test if biochemical devices are equal to the clinical rating system in measuring dyskinesias.
A randomized, double blind, placebo-controlled study employing a mixed parallel group and fixed sequence cross-over design. Patients will be randomized to one of two treatment groups ('E2007' or 'Placebo') in a 1:1 ratio and receive investigational drug treatment concomitant with their standard individualized anti-Parkinsonian therapy for a total of six weeks. Investigational drug treatment for patients in the E2007 treatment group will be started 2 mg E2007 o.d. but will be escalated to 4 mg E2007 o.d. after three weeks.
Mucociliary clearance, in which mucus secretions are cleared from the breathing airways, is the primary defense mechanism for the lungs. Inhaled particles, including microbes that can cause infections, are normally entrapped in mucus on the airway surfaces and then cleared out by the coordinated action of tiny hair-like structures called cilia. Individuals with primary ciliary dyskinesia (PCD) have defective mucociliary clearance, which in turn leads to lung infections and disease. The purpose of this study is to determine how lung disease progresses over time in children and adolescents with PCD.
The purpose of the study is to assess the efficacy and safety of a range of doses of SCH 420814 (preladenant) when used together with a stable dose of L-dopa/dopa decarboxylase inhibitor to treat Parkinson's disease. In this study, we will be comparing 3 doses (1 mg, 2 mg, and 5 mg taken twice a day) of preladenant with placebo (sugar pill). Following an Interim Analysis (temporary hold for new enrollment-ongoing subjects will continue on treatment) to review drug safety, a new dose group of 10 mg (taken twice a day) may be added. Approximately 160 participants will be randomized in this study in approximately 22 study centers worldwide for the first part of this study. Following the Interim Analysis, 40 new participants may be added, for a total of 200 participants. The study is double blind, which means neither you nor your study doctor will know whether you are receiving the study medication or placebo.
The objective of the study is to determine whether Panax Ginseng with multiple interactions with key components of brain signaling pathway, can augment the effects of antipsychotics in Schizophrenia. We are primarily interested to examine the actions of Ginseng combined with antipsychotics in improving the ways patients diagnosed with schizophrenia behave in social environment, store, process and retrieve information.
Healthy volunteers and patients with diseases that involve problems clearing mucus from the lungs will be examined and tested to better understand the reasons for recurring lung infections in these patients and to try to develop better ways to diagnose and treat them. The study will also try to identify the genes responsible for these diseases. Healthy volunteers 18 years of age and older and patients 2 years of age or older with suspected primary ciliary dyskinesia (PCD), variant cystic fibrosis (CF) or pseudohypoaldosteronism (PHA) may be eligible for this study. Patients enrolled in the Natural History Study of Nontuberculous Mycobacteria at NIH or other NIH natural history protocols may also be enrolled. Participants undergo the following tests and procedures during a 1-day visit at the NIH Clinical Center, as follows: All patients and normal volunteers have the following procedures: - Physical examination and review of medical and genetic history and family genetic history. - Lung function test and measurement of oxygen saturation level. - Nitric oxide measurement to measure the amount of nitric oxide production in the nose: A small tube is placed in the nose while the subject breathes through the mouth into a cardboard tube. All patients have the following additional procedures: - Blood tests for liver and kidney function, blood count, immunoglobulins and pregnancy test (where appropriate). - Blood test or buccal scrape (brushing the inside of the cheek) to obtain DNA to look for gene mutations that cause PCD, CF or PHA. - Scrape biopsy of cell lining the inside of the nose: A small toothpick-sized plastic stick with a tiny cup on the end is used to get nasal lining cells to look at the cilia (hair-like structures that move mucus). - Semen analysis (in some men) to test sperm tail function or structure. Patients suspected of having a variant of CF or PHA, including nontuberculous mycobacterial lung disease, have the following additional procedures: - Sweat chloride test: A medicine is placed on the arm to produce sweat; then, a very low level of electric current is applied for 5 to 12 minutes. Sweat is collected in a plastic tube and tested for salt content. - Blood draw for CF genetic testing, if necessary, and to measure levels of the enzyme trypsin. - Saliva collection to measure sodium and chloride content. - Nasal potential difference to measure the electrical activity of the cells lining the inside of the nose: A soft plastic tube filled with a salt solution is passed into the nasal passage and a sterile needle is placed under the skin of the arm. This test provides information about how the lining of the nose is able to get used to changes in temperature and humidity. (Normal volunteers also have this test.)
This study evaluates how effective a new formulation of a marketed drug is in increasing the time to onset of dyskinesia (abnormal twisting, writhing movements) in patients with Parkinson's Disease who have been taking levodopa for less than 2 years.
