Background: Dysesthetic or ongoing extremity pain is a common symptom in all multiple sclerosis (MS) types. Although the pathology of the disease is the demyelination of central neurons, the patients may also complain of neuropathic pain in distal extremities that is generally related to A-delta and C fiber dysfunction. It is not known whether thinly myelinated and unmyelinated fibers are affected in MS patients.

Transverse myelitis is a quite rare complication of hematopoietic stem cell transplantation. The case is here reported of a 49 year old male with diffuse large B cell lymphoma in complete remission who developed transverse myelitis after autologous stem cell transplantation. The patient presented with numbness and sensory loss of the bilateral lower extremities and difficulty in urinating on the 20th day after cell transplantation.

Introduction: Bacterial infections and febrile neutropenia (FN) are major causes of morbidity and mortality in patients with hematological malignancy. The aim of this study was to investigate the incidence and risk factors of infections in lymphoma patients.

Methodology: This retrospective study was conducted on 200 lymphoma patients diagnosed and treated between January 2009 and December 2017 in Diskapi Yildirim Beyazit Training and Research Hospital, a tertiary referral hospital in Ankara, Turkey.

The aim of this study was to evaluate extramedullary (EM) relapses and its features in an allogeneic hematopoietic stem cell transplantation (alloHSCT) cohort, which consisted of patients with acute leukemia and advanced-phase chronic myeloid leukemia. One hundred and twenty-eight alloHSCT patients transplanted between the years 2001 and 2014 were analyzed. EM relapses observed in acute lymphoblastic leukemia (ALL) were more frequent than that of in acute myeloid leukemia (AML) and CML, although calculation of cumulative risk incidence, BM relapse, EM relapse, and non-relapse mortality were considered as competing risks of each other.

Objective: Multiple myeloma (MM) is currently incurable due to refractory disease relapse even under novel anti-myeloma treatment. In silico studies are effective for key decision making during clinicopathological battles against the chronic course of MM. The aim of this present in silico study was to identify individual genes whose expression profiles match that of the one generated by cytotoxicity experiments for bortezomib.

Introduction: Acquired erythroblastopenia (AE) is a rare clinical situation. It is characterized by the reduction of erythroid precursors in the bone marrow together with the low reticulocyte counts in the peripheral blood.

Background: Main secondary causes of AE are drugs, Parvovirus B19 and other infectious reasons, lymphoid and myeloid neoplasia, autoimmune diseases, thymoma and pregnancy.

Background: Immunosuppressive therapy (IST) with anti-T lymphocyte globulin (ATG) plus cyclosporine (CSA) is standard therapy in patients with non-severe aplastic anemia (AA) in need of treatment and severe aplastic anemia (SAA) who do not have an available HLA-matched donor. The aim of this study was to analyze patients submitted to different ATG preparations as first-line treatment.

Patients And Methods: We retrospectively analyzed adult aplastic anemia (AA) patients who received ATG as first-line treatment between 1999 and 2013 to compare hematologic response and survival.

Chronic graft-versus-host disease (cGVHD) is one of the most important causes of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (aHSCT). Occurring in 30% to 70% of patients, cGVHD has a median time to onset of 4 to 6 months and most cases present within 2 years after aHSCT. Here, we present a patient transplanted at the age of 55 who developed refractory cutaneous cGVHD more than 5.

Hemophagocytic syndrome (HPS) is described by an increase in macrophages accountable for extensive phagocytosis of hematopoietic cells. Secondary HPS arises commonly in the presence of infections, neoplasia, autoimmune disorders and immune disorders. Here, we reported a patient with common variable immune deficiency (CVID) and Hodgkin's lymphoma (HL) who later developed EBV linked hemophagocytic lymphohistiocytosis.

Diabetes mellitus (DM) is a frequently encountered disease with important morbidity and mortality. The aim of this study is to document the importance of 1,5-anhydroglucitol (1,5-AG) for the diagnosis of prediabetes and DM, as well as to compare the 1,5-AG with other glycemic markers in order to understand which one is the better diagnostic tool. Between April 2012 and December 2012, 128 participants enrolled in the study.

Hydroxycarbamide is used in the treatment of essential thrombocytosis and other myeloproliferative disorders. We report the case of a 63-year-old woman with essential thrombocytosis who had melanonychia after the long-term use of the hydroxycarbamide with a dose of 1000 mg/day. Two years after the initiation of the hydroxycarbamide, our patient had pain on her toes and melanonychia on her nails.

There are very few data about the relationship between acute myeloid leukemia (AML) prognosis and bone marrow recovery kinetics following chemotherapy. In this study, we aimed to assess the prognostic importance and clinical associations of neutrophil and platelet recovery rates and rebound thrombocytosis (RT) or neutrophilia (RN) in the postchemotherapy period for newly diagnosed AML patients. De novo AML patients diagnosed between October 2002 and December 2013 were evaluated retrospectively.
