RESUMO

Severely immunocompromised patients are at increased risk for uncommon infectious diseases with atypical presentations. Fusarium sp., has been reported in patients with hematological malignancies and prompt diagnosis is necessary due to high mortality. We report a myelodysplastic syndrome (MDS) patient who presented Fusarium solani infection associated with granulocytic sarcoma as an initial presentation of acute myeloid leukemia (AML) transformation. We performed histological examination, immunohistochemistry analysis, culture of the biopsy tissue and DNA sequencing to make a conclusive diagnosis of F. solani and granulocytic sarcoma, reinforcing the necessity of performing complete evaluation of skin lesions in immunocompromised patients.

RESUMO

A risk-adapted treatment strategy is mandatory for myelodysplastic syndromes (MDS). We refined the World Health Organization (WHO)-classification-based Prognostic Scoring System (WPSS) by determining the impact of the newer clinical and cytogenetic features, and we compared its prognostic power to that of the revised International Prognostic Scoring System (IPSS-R). A population of 5326 untreated MDS was considered. We analyzed single WPSS parameters and confirmed that the WHO classification and severe anemia provide important prognostic information in MDS. A strong correlation was found between the WPSS including the new cytogenetic risk stratification and WPSS adopting original criteria. We then compared WPSS with the IPSS-R prognostic system. A highly significant correlation was found between the WPSS and IPSS-R risk classifications. Discrepancies did occur among lower-risk patients in whom the number of dysplastic hematopoietic lineages as assessed by morphology did not reflect the severity of peripheral blood cytopenias and/or increased marrow blast count. Moreover, severe anemia has higher prognostic weight in the WPSS versus IPSS-R model. Overall, both systems well represent the prognostic risk of MDS patients defined by WHO morphologic criteria. This study provides relevant in formation for the implementation of risk-adapted strategies in MDS.

RESUMO

Isochromosome 17q is a relatively common karyotypic abnormality in medulloblastoma, gastric, bladder, and breast cancers. In myeloid disorders, it is observed during disease progression and evolution to acute myeloid leukemia in Philadelphia-positive chronic myeloid leukemia. It has been reported in rare cases of myelodysplastic syndrome, with an incidence of 0.4-1.57%. Two new agents have been approved for treatment of myelodysplastic syndrome/chronic myelomonocytic leukemia. These are the hypomethylating agents, 5-azacytidine and decitabine, recommended by consensus guidelines for high-risk myelodysplastic syndrome patients not eligible for hematopoietic stem cell transplantation. We present a case of chronic myelomonocytic leukemia with normal cytogenetics at diagnosis treated with decitabine (with good response); however, the patient evolved to acute myeloid leukemia with i(17q) shortly after suspending treatment. To the best of our knowledge, this is the first report of acute myeloid leukemia with myelodysplasia-related changes with i(17q) after the use of a hypomethylating agent.

RESUMO

BACKGROUND: In developing countries there is high prevalence of iron deficiency anemia, which causes negative impact on growth, development and quality of life for infant population. Currently several strategies are being elaborated and tested to tackle this problem. OBJECTIVE: To measure anemia prevalence in preschool children. To evaluate fortification effectiveness with 5 or 10 mg of elemental iron/daily added to school meals by increasing hemoglobin levels in anemic children. METHODS: Double-blind, cluster randomized intervention study with 728 students from public network. Blood count was taken at beginning of study, to evaluate anemia prevalence, those anemic were selected for intervention, after intervention new blood count was taken to evaluate fortification effectiveness. Ferrous Sulphate was added in individual dosage of 5 or 10 mg of elemental iron/daily to usual school meal. From 35 schools 3 were randomized to receive 5 mg/daily (group A) and 3 to receive 10 mg/daily (group B). Hemoglobin and hematocrit averages before and after intervention were compared in each group and between them. RESULTS: In group A, the anemia prevalence reduced 34.9 to 12.4%, and in group B 39.0 to 18.7%. In both groups a significant increase in hemoglobin was observed: in group A from 10.1 to 11.5 g/dl (p < 0.01) and in group B from 10.0 to 11.0 g/dl (p < 0.01). There was no statistically significant difference in final levels of hemoglobin among groups. CONCLUSIONS: Both dosages of elemental iron were equally effective in increasing hemoglobin levels, and reducing anemia prevalence. Fortification of school meals was shown to be an effective, low cost and easy to manage intervention.
