RATIONALE: Collecting and storing samples of tissue and blood from patients with cancer to test in the laboratory may help the study of cancer in the future. PURPOSE: This research study is collecting and storing tumor, tissue, and blood samples from patients with pancreatic can…

We are studying the effects of oral water ingestion in patients with orthostatic hypotension. In this study, we are testing the null hypothesis that the blood pressure increase with oral water ingestion will not be diminished if a full prior water dose is given a few hours earlie…

Our experiments are designed to test the overall hypothesis that position-dependent or water-dependent intra-ocular pressure (IOP) spikes occur in humans, and that these challenge ocular homeostasis.

This study collects information to maintain a database on patients with low-grade ovarian or peritoneal tumors. Collecting information about the type of cancer and treatment, as well as details about follow-up care, may help researchers learn and better understand these tumor typ…

The purpose of this study is to identify the causes of asthma that were not previously suspected, to better understand the effects of inhaled steroids on asthma and to identify new way to treat asthma.

Several studies have reported that diabetic subjects have lower plasma vitamin C concentrations than non-diabetic subjects. Although urinary vitamin C loss in diabetic subjects was reported to be increased in two studies, these are difficult to interpret due to lack of controlled…

Sevoflurane is widely used for induction of anaesthesia. Several studies showed EEG abnormalities during mask induction with sevoflurane. The aim of our study was to test the induction target concentration of sevoflurane on the spikes wave occurrence.

The purpose of this protocol is to allow for the careful evaluation of healthy volunteers and individuals with risk for psychiatric disorders or neurodevelopmental disorders, such as autism spectrum disorder for specific protocols at NIH.

In this study the investigators propose to assess the hemodynamic response to the ingestion of 16 fl oz of water. The investigators will test the hypothesis that water ingestion will increase the systemic vascular resistance.

We propose to acquire data and blood samples on all patients being cared for by the Interstitial Lung Disease (ILD) program. Additionally, we will collect data and blood samples from a control group for comparator purposes. In doing so, we will be able to describe the "phenotypic…

Background: * Drugs of abuse have effects on mood, behavior, thinking, and decision making that may encourage people to continue using them and make it difficult for them to stop. Researchers who study these effects are interested in developing new tests to evaluate how drugs an…

Pancreatic exocrine insufficiency is known to impair nutrient absorption, especially fat, but few data exist about protein absorption. We aimed to investigate this question and assess the enzyme substitution efficiency using a sensitive method.

The purpose of this study is to evaluate the effect of sacral nerve magnetic stimulation on the colonic motility in healthy subjects, in incontinent and constipated patients.

Post-operative nausea and vomiting (PONV) is not only unpleasant for patients but also can delay hospital discharge and increase cost of stay. In some cases, when severe vomiting occurs, pain scores seem to be increased. The overall incidence of PONV is 30% and increases to 79% i…

The purpose of this study is to compare two ways to treat patients with Type 2 Diabetes, Standard Care or Case-Managed Care. In-Patient Standard Care is guided by the assigned cardiologist and Out-Patient Standard Care by the existing diabetes care givers. Case-Managed care inv…

The purpose of the study is to investigate factors that are associated with outcomes of injury to the anterior cruciate ligament (ACL) in the knee among patients who are undergoing surgical reconstruction. This study is a registry of all patients having knee surgery at our instit…

The purpose of the data bank is to collect data on joint motion.

Increased numbers of white blood cells called eosinophils can cause disease. To investigate this disease, researchers need blood, urine, sputum, stool, cerebrospinal fluid, skin and/or bone marrow samples to compare to samples from patients with this problem. Some of the samples …

The purpose of this study is twofold: 1. To analyze the clinical features of a cohort of patients with birdshot chorioretinopathy (BCR), an inflammatory bilateral ocular disease, affecting the choroid and the retina. Various imaging techniques will be used to assess the effe…

This study aims to provide long-term follow-up care of patients previously enrolled in a vaccine study that involved poxviral vectors. Vectors are sequences of genetic material that can be used to introduce specific genes into genetic makeup. The study does not involve the use of…
