In this study, all patients will get investigational drug. There will be no comparator drug. This study will evaluate three tumor types: T-cell lymphoma, Indolent B-cell lymphoma, and A...
This study will evaluate the hypothesis that the use of pediatric size phlebotomy tubes reduces RBC transfusions in adult ICU patients compared with the use of adult size tubes.
This is a treatment study to determine if reducing the body's iron stores by blood donation will improve diabetes control and other problems associated with diabetes such as fatty liver di...
High tissue iron is a risk factor for diabetes even within the broad normal range of normal human values. In order to demonstrate the benefits of reducing iron on glucose homeostasis and t...
The purpose of this study is to draw blood from vessels near the liver in patients undergoing liver surgery. This will be performed in both patients with cancer in order to learn more abou...
In the thorax, Hodgkin lymphoma (HL) most frequently involves the anterior mediastinal and paratracheal regions and tends to spread to contiguous nodal groups. Enlarged lymph nodes typically have homo...
Primary mucosa-associated lymphoid tissue (MALT) lymphoma of the trachea is very rare and is easily misdiagnosed as a bronchogenic carcinoma or benign tracheal tumor. Here, we report a clinical case w...
Inflammatory myofibroblastic tumors are a rare type of soft-tissue tumor. Inflammatory myofibroblastic tumors are characterized by rearrangements involving the anaplastic lymphoma kinase gene locus on...
Gradient index (GRIN) lenses can be used to image deep brain regions otherwise inaccessiblevia standard optical imaging methods. Brain tissue aspiration before GRIN lens implantation is a widely adopt...
Therapeutic phlebotomy is recommended for treating hereditary hemochromatosis. However, the procedure and its efficacy for children remain unclear. We describe a young female patient with ferroportin ...
Extranodal lymphoma of lymphoid tissue associated with mucosa that is in contact with exogenous antigens. Many of the sites of these lymphomas, such as the stomach, salivary gland, and thyroid, are normally devoid of lymphoid tissue. They acquire mucosa-associated lymphoid tissue (MALT) type as a result of an immunologically mediated disorder.
A form of undifferentiated malignant LYMPHOMA usually found in central Africa, but also reported in other parts of the world. It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumor in virtually all cases of Burkitt lymphoma. The Epstein-Barr virus (HERPESVIRUS 4, HUMAN) has been isolated from Burkitt lymphoma cases in Africa and it is implicated as the causative agent in these cases; however, most non-African cases are EBV-negative.
Two or more distinct types of malignant lymphoid tumors occurring within a single organ or tissue at the same time. It may contain different types of non-Hodgkin lymphoma cells or both Hodgkin and non-Hodgkin lymphoma cells.
A leukemia/lymphoma found predominately in children and adolescents and characterized by a high number of lymphoblasts and solid tumor lesions. Frequent sites involve LYMPH NODES, skin, and bones. It most commonly presents as leukemia.
