Pneumocystis carinii pneumonia mainly occurs in immunocompromised patients and it is also known of major cause of death in children with acute lymphoblastic leukemia. After consolidation chemotherapy, acute lymphoblastic leukemia children is developed Pneumocystis carinii pneumonia frequently no an opportunistic infection but there were no controlled studies which have been performed to evaluate the usefulness of corticosteroid in Pneumocystis carinii pneumonia with acute lymphoblastic leukemia. We experienced a case of Pneumocystis carinii pneumonia in acute lymphoblastic leukemia with febrile neutropenic 6 years old girl. She was treated with trimethoprim-sulfamethoxazole and prednisone. We report this case with brief review of related literature.

Non-Hodgkin's lymphoma rarely originates from bone, and even more infrequently from a vertebral body. Lymphoblastic lymphoma is a rare type of non-Hodgkin's lymphoma, and results from an abnormality in adaptive immune cells. A 27-year-old man presented with a two-month history of night sweats, weight loss, and severe back pain. Radiological studies demonstrated an osteolytic lesion compressing the subarachnoid space at the T11 level. Posterolateral fusion with decompression was performed and a pathologic examination confirmed lymphoblastic lymphoma of the B-cell precursor type. To our knowledge, this is the first report of solitary lymphoblastic lymphoma from B-cell precursors in of the thoracic spine. Herein, we discuss the presenting symptoms and the management of this rare case of lymphoblastic lymphoma.

Background: To investigate the expression of the fragile histidine triad (FHIT) gene in acute lymphoblastic leukemia and its clinical significance. Materials and Methods: The level of expressed FHIT mRNA in peripheral blood from 50 patients with acute lymphoblastic leukemia (ALL) and in 50 peripheral blood samples from healthy volunteers was measured via RT-PCR. Correlation analyses between FHIT gene expression and clinical characteristics (gender, age, white blood count, immunophenotype of acute lymphoblastic leukemia and percentage of blast cells) of the patients were performed. Results: The FHIT gene was expressed at $2.49{\pm}7.37$ of ALL patients against $14.4{\pm}17.9$ in the healthy volunteers. The difference in the expression levels between ALL patients and healthy volunteers was statistically significant. The rate of gene expression did not significantly vary with immunophenotype subtypes. Gene expression was also found to be correlated with increase of total leukocyte and decrease in platelets, but not with age, gender, immunophenotyping or percentage of blast cells. Conclusions: FHIT gene expression is low in acute lymphoblastic leukemia and could be a useful marker to monitor minimal residual disease. This gene is also a candidate target for the immunotherapy of acute lymphoblastic leukemia.

Background: Acute lymphoblastic leukemia (ALL) is the most common cancer diagnosed in children and represents approximately 25% of cancer diagnoses among those younger than 15 years of age. Aim and Objectives: This study investigated substitutions in the ATP synthase subunit 6 gene of mitochondrial DNA (mtDNA) as a potential diagnostic biomarker for early detection and diagnosis of acute lymphoblastic leukemia. Based on mtDNA from 23 subjects diagnosed with acute lymphoblastic leukemia, approximately 465 bp of the ATP synthase subunit 6 gene were amplified and sequenced. Results: The sequencing revealed thirty-one mutations at 14 locations in ATP synthase subunit 6 of mtDNA in the ALL subjects. All were identified as single nucleotide polymorphisms (SNPs) with a homoplasmic pattern. The mutations were distributed between males and females. Novel haplotypes were identified in this investigation: haplotype (G) was recorded in 34% in diagnosed subjects; the second haplotype was (C) with frequency of 13% in ALL subjects. Neither of these were observed in control samples. Conclusions: These haplotypes were identified for the first time in acute lymphoblastic leukemia patients. Five mutations able to change amino acid synthesis for the ATP synthase subunit 6 were associated with acute lymphoblastic leukemia. This investigation could be used to provide an overview of incidence frequency of acute lyphoblastic leukemia (ALL) in Saudi patients based on molecular events.

A 7-year-old neutered male, domestic shorthair cat presented anorexia and lethargy. The complete blood cell count revealed severe non-regenerative anemia, lymphocytic leukocytosis, neutropenia, and thrombocytopenia. On the peripheral blood smear examination, medium to large lymphoblastic cells with moderate amounts of basophilic cytoplasm were observed in up to 70% of peripheral leukocytes. Feline leukemia and immunodeficiency viruses were not detected using a commercial diagnostic kit. While splenomegaly and blunt margins of the caudoventral liver were observed in abdominal radiography, changes in the intra-abdominal lymph nodes were not remarkable. Ultimately, flow cytometric immunophenotyping from the peripheral blood revealed a negative for B-cell markers (CD21-/CD79a-) and T-cell markers (CD3-/CD4-/CD5-/CD8-). Based on the hematological examination and the immunophenotyping assay, the cat was diagnosed with non-B, non-T acute lymphoblastic leukemia. Here, we report a rare case of non-B, non-T acute lymphoblastic leukemia to raise awareness and provide information on clinical symptoms and laboratory test and immunophenotyping analysis results.

Objective: A case report on the improvement of patients with hematologic malignancies by Ortho-Cellular Nutrition Therapy (OCNT). Methods: A 69-year-old Korean female diagnosed with Stage 4 ACUTE LYMPHOBLASTIC Leukemia (ALL) had a very low platelet count of 8000/µl. Results: The platelet count improved to its normal level after Ortho-Cellular Nutrition Therapy (OCNT). Conclusion: Ortho-Cellular Nutrition Therapy (OCNT) is effective in relieving the symptoms of acute lymphoblastic leukemia patients with thrombocytopenia.

Background: Acute lymphoblastic leukemia (ALL) is the most common cancer diagnosed in children and represents approximately 25% of cancer diagnoses among those younger than 15 years of age. Materials and Methods: This study investigated alterations in the displacement loop (d-loop) region of mitochondrial DNA (mtDNA) as a risk factor and diagnostic biomarker for early detection and diagnosis of acute lymphoblastic leukemia. Using mtDNA from 23 subjects diagnosed with acute lymphoblastic leukemia, the first 450 bp of the d-loop region were amplified and successfully sequenced. Results: This revealed 132 mutations at 25 positions in this region, with a mean of 6 alterations per subject. The d-loop alterations in mtDNA in subjects were all identified as single nucleotide polymorphisms in a homoplasmic distribution pattern. Mutant alleles were observed in all subjects with individual frequency rates of up to 95%. Thirteen mutant alleles in the d-loop region of mtDNA occurred with a high frequency. Novel alleles and locations were also identified in the d-loop of mtDNA as follows: 89 G insertions (40%), 95 G insertions (13%), 182 C/T substitutions (5%), 308 C insertions (19%), and 311 C insertions (80%). The findings of this study need to be replicated to be confirmed. Conclusions: Further investigation of the relationship between mutations in mitochondrial d-loop genes and incidence of acute lymphoblastic leukemia is recommended.

Background: ALL is an irredeemable disease due to the resistance to treatment. There are several influences which are involved in such resistance to chemotherapy, including oxidative stress as a result of the generation of reactive oxygen species (ROS) and presence of hypodiploid cells. Cluster of differentiation 26 (CD26), also known as dipeptidyl peptidase-4, is a 110 kDa, multifunctional, membrane-bound glycoprotein. Aim and objectives: The aim of this study was to evaluate the clinical significance of serum CD26 in patients with acute lymphoblastic leukaemia patients in the post remission induction phase, as well as the relationship between CD26 activity and the oxidative stress status. Materials and Methods: CD26, total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI), in addition to activity of related enzymes myeloperoxidase, glutathione-s-transferase and xanthine oxidase, were analysed in sixty children with acute lymphoblastic leukaemia in the post remission induction phase. Results: The study showed significant elevation in CD26, TOS and OSI levels in patients with acute lymphoblastic leukaemia in the post remission induction phase in comparison to healthy control samples. In contrast, myeloperoxidase, glutathione-s-transferase and xanthine oxidase activities were decreased significantly. A significant correlation between CD26 concentration and some oxidative stress parameters was evident in ALL patients. Conclusions: Serum levels of CD26 appear to be useful as a new biomarker of oxidative stress in children with acute lymphoblastic leukaemia in the post remission induction phase, and levels of antioxidants must be regularly estimated during the treatment of children with ALL.

Leukemia is a malignant disease characterized by uncontrolled clonal proliferation of white blood cells. It is classified depending on clinical course of disease (acute or chronic) and the primary hematopoietic cell line affected (myeloid or lymphoid). Leukemia is often associated with orofacial manifestations, such as oral bleeding, petechiae, oral ulceration, gingival enlargement, mucosal pallor and mental nerve neuropathy. However, trismus has been rarely reported as a sign of leukemia. We present a case of trismus caused by acute lymphoblastic leukemia and emphasize the importance of orofacial manifestations in the early diagnosis of leukemia.
