A case of essential mixed cryoglobulinemia and associated acquired von-Willebrand disease treated with rituximab.

Current treatment options of essential mixed cryoglobulinemia (EMC); include immunosuppressive approaches, such as corticosteroids, cyclophosphamide, plasma exchange, other cytotoxic drugs in moderate to severe manifestations. Some controlled studies have been carried out to assess the efficacy of anti-CD20 monoclonal antibody, rituximab in patients with hepatitis C (HCV) related cryoglobulinemia (CG) and in patients with autoimmune disorders. Recent trials and some case reports demonstrate a beneficial role for rituximab in HCV related mixed CG.

Factor V Leiden mutation in venous thrombosis in southeast Turkey.

Venous thrombosis (VT) is a common disease, with an annual incidence in the general population of approximately 1 per 1,000. Factor V Leiden mutation (G1691A) (FVL) is the most common risk factor in venous thrombosis. The prevalence of FVL for thrombosis varies greatly in different regions of the world.

Ogilvie's syndrome in a patient with multiple myeloma.

Ogilvie's syndrome is characterized by physical examination and radiologic findings indicative of mechanical obstruction but in which no physical obstructive process can be found. Many factors have been associated with this syndrome which include electrolyte imbalance, systemic infection, drugs, and occasionally, neurologic disease. A case of acute colonic pseudoobstruction is presented which developed in a patient with multiple myeloma.

Prothrombin G20210A gene mutation with LightCycler polymerase chain reaction in venous thrombosis and healthy population in the southeast of Turkey.

Venous thrombosis (VT) is a common disease, with an annual incidence in the general population of approximately 1 per 1000. The prevalence of genetic risk factors for thrombosis varies greatly in different parts of the world. Prothrombin G20210A (PT G20210A) gene mutation has been recently identified as a common risk factor in venous thrombosis.

Non-Hodgkin's lymphoma in southeast Turkey: clinicopathologic features of 490 cases.

We have carried out a retrospective analysis of 490 non-Hodgkin's lymphomas (NHLs), followed at our clinic, with the purpose of evaluating the clinicopathologic features of these patients. The patients were assessed with regard to their characteristics including age, gender, histologic distribution, stage, extranodal involvement, presenting symptoms, and biopsied site. Of the patients 314 (64%) were male and 176 (36%) were female.

Hepatitis C virus in patients with non-Hodgkin's lymphoma in southeastern Anatolia region of Turkey: a prospective case-control study of 119 patients.

Hepatitis C virus (HCV) has been associated with several extrahepatic disorders including mixed cryoglobulinemia (MC), autoimmune thyroiditis, Sjogren's syndrome. Such associations have led to the suggestion that HCV may participate in the development of various immunmediated disorders. Recently, it has been hypothesised that HCV might act as a trigger for the development of monoclonal B-cell disorders such as non-Hodgkin's lymphoma (NHL).

Treatment of blastic phase chronic myeloid leukemia with mitoxantrone, cytosine arabinoside and high dose methylprednisolone.

Fourteen patients with blastic phase chronic myelogenous leukemia received combination chemotherapy with mitoxantrone 5 mg/m2 intravenously daily for 3 days, cytosine arabinoside 100 mg/m2 intravenously over 2 hours bid for 7 days and high dose methylprednisolone 1000 mg/day intravenously for 5 days. The patients' mean age was 52 +/- 10 (range 34-64) and Philadelphia chromosome was positive in all. Five patients (35%) achieved complete remission and four patients (28%) had a partial remission.

Hodgkin's disease variant of Richter's transformation: a case report.

Hodgkin's disease rarely develops in patients with B-chronic lymphocytic leukemia. Patients developing Hodgkin's disease after the diagnosis of chronic lymphocytic leukemia have been called the "Hodgkin's disease variant of Richter's transformation." We present a 62-yr-old man with a 17-mo history of chronic lymphocytic leukemia, who clinically and hematologically on remission was admitted to our clinic because of rapidly developing right cervical lymphadenopathy.
