Background: The aim of this paper was to present the incidence rates of leukemia and multiple myeloma (MM) in Golestan province located in northeastern Iran during 2004-2009. Materials and Methods: This was a descriptive cross-sectional study. Data on newly diagnosed (incident) leukemia and MM cases were obtained from collected from Golestan population-based cancer registry. Data was entered into CanReg-4 software. Age standardized incidence rates (ASR) (per 100000 person-years) for leukemia and MM were calculated. Data on Golestan population was obtained from the data of Iranian national census in 2006. Results: Totally, 11036 new cancer cases were registered in GPRC from 2004-2009. Leukemia and MM accounted for 693 and 124 of cases, respectively. The mean age in patients with leukemia and MM was 43.8 and 62.4 years, respectively. The ASRs for leukemia among men and women were 10.4 and 7.8, respectively (p<0.001). The ASRs for MM were 2.1 and 2 in men and women, respectively (p=0.93). The rate of leukemia was significantly higher in rural areas (p=0.02) whereas the incidence of MM was higher in urban areas (p<0.001). Conclusions: Our results showed a high incidence rate of leukemia in Golestan province of Iran. The incidence of leukemia was significantly higher in males and residents of rural areas. High exposure to pesticides and other agricultural related products may be a possible explanation for epidemiological pattern of leukemia in this area. Determining and controlling important risk factors, especially environmental factors, of leukemia may lead to decrease in its burden in Golestan province of Iran.

Cancer is a major health problem facing the entire world, and Kazakhstan is not the exception. The aim of this study was to present an epidemiological assessment of leukemia in the population of Kazakhstan during 2003-2012. This descriptive and retrospective study was based on data obtained from all oncological organizations of the whole country. Age standardized incidence rates per 100,000 population for leukemia were calculated. Totally, 6,741 new cases of leukemia were registered in Kazakhstan during the 10 year period. The mean age of patients with leukemia was 48.5. The ASRs for leukemia among men and women were 5.3 and 3.6, respectively (p<0.001). In conclusion, our results showed a high incidence rate of leukemia in Kazakhstan, especially in the north of the country. The incidence of leukemia was significantly higher in males and increased with age. Determining and controlling important risk factors of leukemia may lead to decrease in its burden.

Intracranial chloroma may occur in leukemia, although they are rare. A 23-year-old female complained diplopia. Brain magnetic resonance MR imaging showed tumors in the both cavernous sinus, both tentorial and anterior falx. Gamma-Knife radiosurgery was performed with maximal dose; 20Gy, marginal dose; 10Gy. Peripheral blood smear revealed leukemia, and bone marrow aspiration biopsy showed acute lymphocytic leukemia. Two weeks later, MR image for the stereotactic biopsy noticed markedly decreased tumor size. Biopsy result was lymphocytic leukemia. She received conventional radiation therapy, chemotherapy, and bone marrow transplantation. Brain involvement by acute lymphocytic leukemia is very rare. Even though chloroma are sensitive to radiation therapy, prognosis is poor because of the gravity of the underlying disease and association with impending blast transformation. The authors reports a intracranial chloroma by acute lymphocytic leukemia.

Leukemia is a blood disease that occurs in the abnormal process of leukocyte maturation. Its main medical treatment is chemical therapy and bone medical transplant. But its treatments give rise to ill effects and sequela. At present, the cause of leukemia is not fully understood. But oriental concept of curing leukemia is the holistic thinking that emphasizes the unity, wholeness, and the relationship between the human organs, including western medical concept of blood cause. So it is estimated that holistic medical treatment in oriental medicine could present new medical way of curing leukemia. I read over the diary on struggles against leukemia, survey on the leukemia patients, and, medical charts in the oriental clinics that treated in the holistic way, and I interviewed the leukemia patients. With these materials, I classified the early main attacking symptoms according to the chief complaints of one hundred leukemia patients. With these results collected, I present new alternative treatment by oriental medical diagnosis. The chief early complaints that leukemia patients give are fatigue, enervation, cold, contusion, fever, high fever, sweating at sleep, myalgia, arthralgia, and dizziness, in order of main symptoms. Fatigue occurs mainly by spleen and stomach weakness and marrow shortage. So it is estimated that It is important to treat the spleen that is responsible for supplementing the marrow. Because the leukemia patients have anemia and hemorrhage, to treat the spleen is important for hematopoiesis and controlling blood. In case of cold, it penetrates into the body when the body is weak. So its treatment is to increase body's health. But the cause of fever is difficult to classify into outer cause and inner cause. But in case of children under 14 years old, fever is the main sypmptom. I think this is because children have the body with pure vital energy. Hemorrhage is thought to be the result of yin-lack and heat-miasma of spleen and stomach channels. Contusion occurs from the qi-weakness and the not-controlling-blood. Sweating at sleep is from the yin-weakness. It is found with all weak symptoms. Dizziness is from the yin-blood impairment. Weight-loss is from the marrow shortage. Myalgia and arthralgia is mainly from inner weakness, not outer maisma. Most leukemia patients have the idea that holistic treatment of leukemia could be of assistance and give help to the low immunity. So it is expected that holistic medical treatment could contribute to knowing the cause and treatment of leukemia, and give people reliability on oriental medical treatment, through the profound diagnosis of leukemia.

Background: Although the cause in most cases of childhood leukemia is not known, the contribution of environmental risk factors in the context of genetic predisposition has been reported with inconsistent results. The aim of this study was to examine association of childhood leukemia with maternal factors especially during pregnancy, to help in avoiding risk factors. Materials and Methods: This case-control study included children younger than 18 years diagnosed with leukemia from 2008 to 2012. Controls were randomly selected and individually matched to cases with respect to age, sex, and residency. All variables were compared between cases and control to determine any significant association with leukemia. Results: Statistically significant associations between risk of childhood leukemia with mother's education (p=0.001), occupation (p=0.0005) and pesticides exposure (p=0.005) during pregnancy were found. However, there were no significant links with maternal age (p=0.090), history of fetal loss (0.85), history of radiography during pregnancy (p=0.400), history of drug intake (p=0.689) and infection (p=0.696) during pregnancy. Conclusions: The results showed increased risk of leukemia in children whose mothers were working in agriculture and were exposed to pesticides during pregnancy. The further study needs to be investigated to know association of various maternal risk factors with leukemia which remained unknown in this study.

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.

Purpose: The purpose of this study was to develop parent coaching domains for the health management of childhood leukemia survivors. Methods: In this study, we conducted a literature review and in-depth interviews with 6 parents of childhood leukemia survivors who were identified using convenience sampling. We identified areas of parent coaching through the 4 stages of the GROW model, which are: goal setting, realistic grasp, confirmation of realization, and search for alternatives. Results: Nine domains and 27 subcategories emerged from the study. The 9 parent coaching domains for the health management of childhood leukemia survivors were routine life management, education and information provision, emotional support for the surviving children, social support for the surviving children, follow-up management, family support, school life management, symptom management, and improvement of growth and development. Conclusion: This research developed 9 parent coaching domains for the health management of children surviving leukemia. The results of this study are expected to contribute to the efficient health management of childhood leukemia survivors by enabling practitioners to continuously identify new coaching domains as needed for their health management. Researchers should improve the health management of childhood leukemia survivors by developing nursing interventions for these new coaching areas.

Background: While many studies have concluded that local traffic density is positively associated with childhood leukemia, the results are inconsistent. We therefore performed a meta-analysis to assess the relationship between traffic density and the risk of childhood leukemia. Methods: A systematic literature review was carried out using PubMed, EMBASE, and the Cochrane Library from January 1979 to December 2013. We selected and assessed journal articles evaluating the relationship between local traffic density and the risk of leukemia in children. The analysis was carried out using STATA version 12.0. Results: A total of 11 articles, including 12 estimates of effect, were included in our meta-analysis. The summary effect size from the random-effects model, expressed as an odds ratio, was 1.03 (95% CI: 0.98-1.09, p=0.002). No significant association between traffic density and the risk of childhood leukemia was found. Similar conclusions were found on subgroup analysis. Conclusions: The results of our meta-analysis suggested no association between traffic density and the risk of childhood leukemia. This implies that living in close proximity to roads with heavy traffic may not increase the risk of childhood leukemia. However, further high-quality prospective trials are needed to support these results.

We report a case of a 13-year-old girl with acute lymphoblastic lymphoma- leukemia, who presented with a cardiac metastasis in the right ventricle, resulting in a pulmonary embolism. At the time of her leukemia diagnosis, a cardiac mass was incidentally found. The differential diagnosis for this unusual cardiac mass included cardiac tumor, metastasis, vegetation, and thrombus. Empirical treatment was initiated, including anticoagulation and antibiotics. She underwent plasmapheresis and was administered oral prednisolone for her leukemia. Five days later, she experienced sudden hemodynamic collapse and required extracorporeal membrane oxygenation insertion and emergency surgery. These interventions proved futile, and the patient died. Pathology revealed that the cardiac mass comprised an aggregation of small, round, necrotic cells consistent with leukemia. This is the first known case of acute lymphoblastic leukemia presenting as a right ventricular mass, with consequent fatal acute pulmonary embolism. A cardiac mass in a child with acute leukemia merits investigation to rule out every possible etiology, including vegetation, thrombus, and even a mass of leukemic cells, which could result in the fatal complication of pulmonary embolism.

The differentiation of leukemia cells into mature cells is a major target of the human leukemia therapy. As differentiated leukemia cells lose their proliferative and tumor-forming abilities, differentiation inducers may be useful for the treatment of leukemia. In this study, the experiments were designed to determine whether diallyl disulfide (DADS) regulates expressions of tumor suppressor protein PTEN (phosphatase and tension homologue) in HL60 cells. DADS causes upregulation of PTEN in a time- and dose-dependent manner, which was correlated with decrease of phospho-Akt level. These results suggest that DADS induces upregulation of PTEN in human leukemia cells. These results suggest that DADS may be a useful anticancer agent for management of human leukemia.
