1.  An Acute Transverse Myelitis Attack after Total Body Irradiation: A Rare Case 
Case Reports in Hematology  2013;2013:523901.
Total body irradiation (TBI) combined with chemotherapy is widely used as a pretreatment regimen of bone marrow transplantation (BMT) in hematologic disorders. Late complications related to TBI as part of the conditioning regimen for hematopoietic stem cell transplantation have been revealed. Acute transverse myelitis (ATM) is a neurological syndrome characterized by disorder of motor, sensorial, and autonomic nerves, and tracts at medulla spinalis, which is resulted from involvement of spinal cord. In this paper, we presented an ATM attack developed after TBI in a patient with acute lymphoblastic leukemia (ALL) as it is a rarely seen case.

2.  Successful Treatment of Gastric Relapse in Multiple Myeloma with Bortezomib after Autologous Hematopoietic Stem Cell Transplantation (autoHSCT) 
We report a case of 59-year-old Turkish man with history of mitral valve replacement (MVR) and chronic obstructive pulmonary disease (COPD) who was diagnosed with stage IIIA IgG lambda multiple myeloma (MM) in 1997. He underwent autologous hematopoietic stem cell transplantation after a conditioning regimen with melphalan 200mg per body area (m2) in February 2006. On February 2011, he was admitted to the emergency service of university hospital with complaints of hematemesis and melena. Pathological evaluation of gastric biopsy, obtained from a lesion of small gastric curvature, showed the gastric mucosa infiltrated by neoplastic plasma cells, monoclonal lambda light chain positive. The patient was considered as having local gastric relapsed disease and was treated with 2 cycles of bortezomib. He achieved an excellent local response after 2 cycles of bortezomib, cyclophosphamide and prednisone (BEP) regimen, with healing of gastric ulcer and no recurrence of the hematemesis or melena.

3.  Flow Cytometry Method as a Diagnostic Tool for Pleural Fluid Involvement in a Patient with Multiple Myeloma 
Multiple myeloma is a malignant proliferation of plasma cells that mainly affects bone marrow. Pleural effusions secondary to pleural myelomatous involvement have rarely been reported in the literature. As it is rarely detected, we aimed to report a case in which pleural effusion of a multiple myeloma was confirmed as true myelomatous involvement by flow cytometry method. A 52-years old man presented to our clinic with chest and back pain lasting for 3 months. On the chest radiography, pleural fluid was detected in left hemithorax. Pleural fluid flow cytometry was performed. In the flow cytometry, CD56, CD38 and CD138 found to be positive, while CD19 was negative. True myelomatous pleural effusions are very uncommon, with fewer than 100 cases reported worldwide. Flow cytometry is a potentially useful and simple method for detection of pleural fluid involvement in multiple myeloma.

4.  Comparison of Plateletpheresis on the Fenwal Amicus and Fresenius Com.Tec Cell Separators 
Summary
Background
A variety of apheresis devices are now available on the market for plateletapheresis. We compared two apheresis instruments (Fenwal Amicus and Fresenius COM.TEC) with regard to processing time, platelet (PLT) yield and efficiency, and white blood cell (WBC) content.
Material and Methods
Donors undergoing plateletpheresis were randomly separated into two groups (either the Amicus or the COM.TEC cell separator).
Results
In the pre-apheresis setting, 32 plateletpheresis procedures performed with each instrument revealed no significant differences in donors’ sex, age, weight, height and total blood volume between the two groups. However, the pre-apheresis PLT count was higher with the COM.TEC than with the Amicus (198 × 103/μl vs. 223 × 103/μl; p = 0.035). The blood volume processed to reach a target PLT yield of ≥3.3 × 1011 was higher in the COM.TEC compared to the Amicus (3,481 vs. 2,850 ml; p < 0.001). The median separation time was also significantly longer in the COM.TEC than in the Amicus (61 vs. 44 min; p < 0.001). 91 and 88% of the PLT products collected with the Amicus and the COM.TEC, respectively, had a PLT count of >3.3 × 1011 (p = 0.325). All products obtained with both instruments had WBC counts lower than 5 ↔ 106, as required. There was no statistical difference with regard to collection efficiency between the devices (55 ± 15 vs. 57 ± 15%; p = 0.477). However, the collection rate was significantly higher with the Amicus compared to the COM.TEC instrument (0.077 ± 0.012 × 1011 vs. 0.057 ± 0.008 × 1011 PLT/min; p < 0.001).
Conclusion
Both instruments collected platelets efficiently. Additionally, consistent leukoreduction was obtained with both instruments; however, compared with the COM.TEC instrument, the Amicus reached the PLT target yield more quickly.

5.  Acute Lymphoblastic Leukemia Associated with Brucellosis in Two Patients with Fever and Pancytopenia 
Yonsei Medical Journal  2006;47(5):741-744.
Brucellosis is a disease involving the lymphoproliferative system, which may lead to changes in the hematological parameters; however, pancytopenia is a rare finding. However, malignant diseases in association with brucellosis are rarely the cause of pancytopenia. Herein, two cases with fever and pancytopenia, diagnosed as simultaneous acute lymphoblastic leukemia and brucellosis are presented. Anti-leukemic therapy and brucellosis treatment were administered simultaneously, and normal blood parameters obtained. The first patient is in complete remission; the other recovered from the brucellosis, but later died due to a leukemic relapse.

6.  Clinicopathologic Characteristics and Therapeutic Outcomes of Primary Gastrointestinal Non-Hodgkin's Lymphomas in Central Anatolia, in Turkey 
Yonsei Medical Journal  2006;47(1):22-33.
Primary gastrointestinal lymphoma is a common presentation of non-Hodgkin's lymphoma. The main controversy arises when many aspects of its classification and management are under discussion, particularly regarding roles for surgical resection. The aim of this study was to evaluate clinicopathologic characteristics and the therapeutic outcome of primary gastrointestinal non-Hodgkin's lymphoma. We carried out a retrospective analysis of 74 patients who were presented to our center with histopathological diagnosis of primary gastro-intestinal non-Hodgkin's lymphoma between 1990 and 2001. All patients have been staged according to Lugano Staging System. For histopathological classification, International Working Formulation was applied. The treatment choice concerning the surgical or non-surgical management was decided by the initially acting physician. Treatment modalities were compared using the parameters of age, sex, histopathological results, stage, and the site of disease. Of the 74 patients, 31 were female and 43 were male, with a median age of 49 years (range 15-80). The stomach was the most common primary site and was seen in 51 of 74 patients (68.9%). The intermediate and high grade lymphomas constituted 91.9% of the all cases. In a median follow-up of 29 months (range 2-128), 20 out of 74 patients died. There was a three year overall survival rate in 65.4% of all patients. The three year overall survival rate was better in stage I and II1 patients who were treated with surgery plus chemotherapy (+/-RT) than those treated with chemotherapy alone (93.7% vs. 55.6%, p < 0.05). The stage and presence of B symptoms affected the disease free survival and overall survival significantly, but the histopathologic grade only affected the overall survival. On the basis of these results, we suggest that surgical resection is necessary before chemotherapy in early stage (stage I and II1) patients with gastrointestinal non-Hodgkin's lymphomas because of the significant survival advantage it would bring to the patient.
