OBJECTIVE:
To investigate the overview of thrombosis in myeloproliferative neoplasms(MPN) patients, and to explore the risk factors of thrombosis at diagnosis and during follow-up.
METHODS:
The clinical data of 388 MPN patients treated in our hospital were collected. The patients were followed up by outpatient and phone. The risk factors of thrombosis were analyzed by statistical methods.
RESULTS:
Among 388 MPN patients, 161 patients (41.49%) showed thromboses at diagnosis or during follow-up. Among them, 92.55% were arterial thromboses, 146 cases (96.27%) were complicated with thromboses at diagnosis, and 36 cases (11.46%) showed newly thromboses or progression of previous thromboses among the 314 received full follow-up patients. Age (P<0.001, HR:1.033, 95%CI:1.016-1.051), JAK2V617F mutation (P=0.037, HR:1.72, 95%CI: 1.033-2.862), hypertension (P<0.001, HR:2.639, 95%CI:1.659-4.197) and hyperlipidemia (P<0.001, HR:2.659, 95%CI:1.626-4.347) were the independent risk factors affecting thrombosis at diagnosis of the patients. During the follow-up, age (P=0.016, HR:1.032, 95%CI: 1.006-1.059) and previous thrombosis history (P=0.019, HR:2.194, 95%CI: 1.135-4.242) were the independent risk factors affecting the progression of thrombosis at different sites or on the basis of the previous thrombosis in the patients.
CONCLUSION
Patients with advanced age, JAK2V617F mutation or complicated with hypertension and hyperlipidemia shows a higher risk of thrombosis at diagnosis, while the patients with advanced age or previous thrombosis history shows a higher risk of progression of thrombosis during the follow-up.

Philadelphia chromosome-positive acute myeloid leukemia (Ph+AML) is a rare disease characterized by a poor prognosis with resistance to standard chemotherapy. We report a patient with Ph+AML with a minor BCR-ABL-positive mRNA transcript who achieved a hematologic, cytogenetic, and major molecular complete response after cytarabine-based chemotherapy followed by imatinib. After more than 6 months of continuous imatinib therapy, the patient is in continuous complete remission. Our results show that imatinib mesylate is effective in treating Ph+AML.

In this report, we present a case of a patient with Philadelphia chromosome-positive (Ph+) B-cell acute lymphoblastic leukemia after renal transplantation. The patient, a 65-year-old man, had received a kidney transplantation 20 years prior to diagnosis with Ph+ precursor B-cell ALL. Because he was refractory to intensive chemotherapy and had refused to receive additional intensive chemotherapy, he was treated with imatinib and dexamethasone. While this patient experienced a complete hematologic and cytogenetic response, he did not show a complete molecular remission. Eighty days after imatinib combination therapy, the patient relapsed and died from intracerebral hemorrhage.

STUDY DESIGN: This is a retrospective study. OBJECTIVES: We will discuss clinical outcomes of adult traumatic atlantoaxial rotatory subluxation (Fielding type I) and verify the correlation between the clinical outcomes and radiological reduction rate. SUMMARY OF LITERATURE REVIEW: Atlantoaxial rotatory subluxation which usually occur in children by non-traumatic sources or minor trauma has been discussed persistently. However, studies of atlantoaxial rotatory subluxation which occur in adults over 20 years old, especially by traumatic injury is rare. MATERIALS AND METHODS: From October 2004 to April 2011, thirty patients diagnosed of traumatic atlantoaxial rotatory subluxation with 6 months follow-up period were enrolled in the study. After diagnosis, we started treating Halter traction with 5 lbs. We discontinued traction when the patient recovered over 90% of ROM and applied Philadelphia collar to the patient. We measured visual analogue scale (VAS) for cervical pain and ROM. We measured atlanto-dens interval (ADI) and lateral mass-dens interval (LDI) difference using three-dimensional computed tomography (3D-CT) to validate radiological reduction rate. RESULTS: At the end of follow-up, none of the patients complained over pain and all recovered to full ROM. ADI was in normal range during the whole treatment period. LDI difference gradually decreased during treatment period, however, only 8 cases (26.7%) came back to normal range. CONCLUSIONS: In traumatic atlantoaxial rotatory subluxation (Fielding type I), satisfactory clinical outcomes such as pain relief or ROM improvement using traction and the radiological reduction rate was also improved but it failed to achieve a complete reduction of LDI difference in radiography.

The ider(22)(q10)t(9;22)(q34;q11.2) is a rare secondary karyotypic aberration of Philadelphia chromosome positive chronic myelogenous leukemia (Ph+ CML) and was associated with disease progression and poor clinical outcomes in most of the previously reported cases. We experienced a case of Ph+ CML with the occurrence of ider(22)(q10)t(9;22)(q34;q11.2) as clonal evolution preceding an hematologic feature of accelerated phase for 3 years. So this chromosomal abnormality was not always correlated with poor prognosis. Relevant literature was reviewed.

A 14 years old female patient with chronic myelocytic leukemia was presented. Characteristic blood features of peripheral blood smear and bone marrow findings, clinical symptoms and signs, Philadelphia chromosome are confirmative for the diagnosis of the disease. Pertinent literatures and references were also reviewed briefly.

10.Can Minor bcr/abl Translocation in Acute Leukemia Be Discriminated from Major bcr/abl by Modified FISH Analysis?.
Korean Journal of Hematology 2000;35(3-4):271-278
BACKGROUND: Bcr/abl translocation is a recurring chromosome aberration in acute leukemia (AL). About half of the translocation in AL occur at minor bcr region (m-bcr) and remaining half at major bcr region (M-bcr). PCR method has been the practical tool for this discrimination. Recently, modified probe of FISH (fluorescence in situ hybridization) for bcr/abl was designed. In this study, we investigated whether FISH analysis with this new probe can discriminate between m-bcr and M-bcr. METHODS: Fourteen cases harboring m-bcr confirmed by qualitative PCR method were enrolled for this study. Except for two cases, all were diagnosed as AL. Cytogenetic results showed Philadelphia chromosome (Ph) in 10 cases all of which the diagnosis was AL. FISH analysis was performed on the archival samples for cytogenetic study in all cases. RESULTS: Eleven out of 14 cases showed bcr/abl translocation signals by FISH. It was of note that all of these translocation signals were different from those seen in M-bcr with thesame probe. The point of breakage onto the hybridized probe for bcr region made the difference. The resultant number of fusion signal is two in m-BCR and one in M-bcr. All Ph- positive cases showed m-bcr FISH signals. One case of Ph-negative AL in remission was m-bcr-positive by FISH. Remaining three cases of Ph-negative were bcr/abl-negative by FISH. CONCLUSION: With recently designed bcr/abl FISH probe, m-bcr was clearly discriminated from M-bcr. In addition, one case of AL in morphological and cytogenetic remission and positive for m-bcr by PCR was revealed to have significant amount of residual leukemic cells by FISH. These results demonstrate that FISH can be a powerful tool for the detection and quantitative analysis of m-bcr both at initial diagnosis and follow-up thereafter.
