Aplastic anemia (AA) is a hematological disease characterized by the deficient production of blood cells. The incidence of AA worldwide is low (1-5 new cases per 10(6) individuals per year). In contrast to other countries, no current reports exist on the incidence of this disorder in Mexico. In the present study, we have determined the incidence of AA in a(More)
Acute lymphoblastic leukemia (ALL) has been recognized as a hematologic neoplasia that originates at the level of a primitive lymphoid stem/progenitor cell. To date, however, the biology of the hematopoietic system in this disorder is still not fully understood. In the present study, we have determined the progenitor cell content (including myeloid,(More)
BACKGROUND Over the past decade, umbilical cord blood (UCB) banking and transplantation have increased significantly worldwide. The experience in developing countries, however, is still limited. In January 2005 the Mexican Institute of Social Security (IMSS) initiated its UCB banking and transplantation program. This study reports on the experience(More)
BACKGROUND In January 2005, the Cord Blood Bank (CBB) at the Mexican Institute of Social Security initiated activities. Herein, we describe the experience generated during this period (January 1, 2005-December 31, 2009). STUDY DESIGN AND METHODS Good manufacturing practices and standard operating procedures were used to address donor selection, as well as(More)
Fanconi anemia (FA) is a rare autosomal recessive disorder characterized by bone marrow (BM) failure and a wide array of physical abnormalities. Around 9% of FA patients develop acute myeloid leukemia (AML), which makes FA a good genetic model to study leukemogenesis. To date, however, no information exists on the functional integrity of the hematopoietic(More)
von Willebrand's disease (VWD) is the most commonly inherited bleeding disorder. For a long time, it has been said that VWD was absent in some countries due to ethnical differences. Information about the prevalence of VWD in Mexico remains unclear, owing largely to poor awareness and diagnosis of the disease. The aim of this study was to objectively(More)
