Site-Specific Survival of Extra Nodal Diffuse Large B-Cell Lymphoma and Comparison With Gastrointestinal Diffuse Large B-Cell Lymphoma.

Background: Diffuse large B-cell lymphoma (DLBCL) constitutes 30% of all non-Hodgkin's lymphomas. It can present as a nodal disease or as an extra nodal disease. Based on the site of origin, extra nodal DLBCL (EN-DLBCL) may have a distinct clinical outcome.

Eculizumab as a Treatment for Hyper-Haemolytic and Aplastic Crisis in Sickle Cell Disease.

Background: Patients with sickle cell disease can experience various crises including sequestration crisis, haemolytic crisis and aplastic crisis. Due to alloantibody formation, transfusion alloantibodies can cause a haemolytic crisis. Treatment involves avoiding packed red blood cell transfusions, as well as intravenous immunoglobulin, steroids and eculizumab to decrease the chances of haemolysis.

Chronic Atrophic Gastritis Presenting as Hemolytic Anemia due to Severe Vitamin B12 Deficiency.

Vitamin B12 is an essential nutrient which plays an important role in neurological function, hematopoiesis, and DNA synthesis. Low levels usually stem from either poor intake or a malabsorptive process. Presently, the most common cause of vitamin B12 deficiency is food-bound cobalamin malabsorption, which occurs when there is impaired release of vitamin B12 from ingested food due to an outstanding factor preventing the release of the nutrient from its transport protein.

Erythropoietin-Associated Posterior Reversible Encephalopathy Syndrome.

Introduction: This case demonstrates an underrecognized cause of posterior reversible encephalopathy syndrome (PRES).

Case Report: We report a 51-year-old male with a history of essential hypertension without preexisting renal impairment who presented with 3 days of occipital headache and convulsive status epilepticus in the setting of refractory hypertension. He had been receiving outpatient human recombinant erythropoietin injections for virally mediated bone marrow suppression, which worsened his baseline hypertension.

C3 Glomerulopathy and Atypical Hemolytic Uremic Syndrome: Two Important Manifestations of Complement System Dysfunction.

The advances in our understanding of the alternative pathway have emphasized that uncontrolled hyperactivity of this pathway causes 2 distinct disorders that adversely impact the kidney. In the so-called atypical hemolytic uremic syndrome (aHUS), renal dysfunction occurs along with thrombocytopenia, anemia, and target organ injury to multiple organs, most commonly the kidney. On the other hand, in the so-termed C3 glomerulopathy, kidney involvement is not associated with thrombocytopenia, anemia, or other system involvement.

Profile of panobinostat and its potential for treatment in solid tumors: an update.

The histone deacetylase (HDAC) inhibitors have emerged as novel therapies for cancer. Panobinostat (LBH 589, Novartis Pharmaceuticals) is a pan-deacetylase inhibitor that is being evaluated in both intravenous and oral formulations across multiple tumor types. Comparable to the other HDACs, panobinostat leads to hyperacetylation of histones and other intracellular proteins, allowing for the expression of otherwise repressed genes, leading to inhibition of cellular proliferation and induction of apoptosis in malignant cells.

Renal Medullary Carcinoma Masquerading as Bilateral Breast Carcinoma Category: Case Report.

Metastatic disease to the breast accounts for less than 1% of all breast carcinoma. Here we describe an unusual case of a 34-year-old black female with history of sickle cell trait who presented to her gynecologist with bilateral palpable breast masses. Based on initial workup including pathology results from biopsies of both breast masses, she was diagnosed with bilateral breast cancer.

An Unusual Presentation of Isolated Leptomeningeal Disease in Carcinoma of Unknown Primary With Pancreatic Features.

Leptomeningeal disease (LMD) can occur in a small percentage of patients with active metastatic cancer. However, we report a case of LMD occurring during disease remission in a patient with carcinoma of unknown primary with panreaticobiliary features. A 45-year-old woman was found with mediastinal and abdominal lymphadenopathy with lymph node biopsy consistent with adenocarcinoma, expressing immunomarkers CK7, CK20, and Ca19-9 along with markedly elevated serum Ca19-9 level.
