Polycyclic aromatic hydrocarbons (PAHs) on virgin polystyrene (PS) and PS marine debris led us to examine PS as a source and sink for PAHs in the marine environment. At two locations in San Diego Bay, we measured sorption of PAHs to PS pellets, sampling at 0, 1, 3, 6, 9, and 12 months. We detected 25 PAHs using a new analytical method with comprehensive(More)
Twenty patients with massive trichuriasis were studied with double contrast barium enema. The following changes were observed: 1) Impregnation defects of the colonic wall probably due to abundant mucous secretions. 2) Granular features. 3) Pear-shaped caecum. 4) Radiolucid ringlike images with some contrast material in its center, similar to those seen in(More)
Using non-myeloablative conditioning, allogeneic hematopoietic stem cell transplantation (HSCT) was conducted in 43 ALL patients in a CR2. The median age of the patients was 19 years. Patients received oral busulfan 4 mg/kg/day for 2 days; i.v. cyclophosphamide 350 mg/m(2)/day for 3 days; and i.v. fludarabine 30 mg/m(2)/day for 3 days. Oral cyclosporin A 4(More)
Using a reduced-intensity stem cell transplantation (RIST) schedule, 24 patients with Philadelphia (Ph1) (+) chronic myelogenous leukemia (CML) in first chronic phase (CP) were prospectively allografted in four Latin American countries: México, Brazil, Colombia and Venezuela, using HLA-identical siblings as donors. The median age of the patients was 41(More)
We analyze the prevalence and clinical features of a group of patients with t(8;21) (q22;q22) acute myeloblastic leukemia, identified in a single institution in México over a 10-year period. Fifteen patients presented at the Centro de Hematología y Medicina Interna de Puebla from February 1995 to August 2005; only nine were treated and followed in the(More)
Twenty-eight children and adults underwent transplantation with allogeneic umbilical cord blood cells (UCB) using a non-ablative conditioning regimen; there were 15 males and 13 females. Seven patients were grafted because a non-malignant condition and 21 for a malignant disease. The median age was 8 years (range 4 months-72 years). Ten UCB were obtained(More)
OBJECTIVE To identify determinants of early outcome in spontaneous lobar hemorrhage. MATERIALS AND METHODS From 2500 acute stroke patients included in a prospective hospital-based stroke registry over a 12-year period, 97 cases of lobar hematoma were selected. Determinants of in-hospital mortality were studied in multiple regression models. RESULTS(More)
Using the Mexican approach to conduct nonablative stem cell transplantation (NST), we have prospectively performed 58 allografts in individuals with various malignant and nonmalignant hematological diseases using sibling donors, either HLA identical (6/6) or compatible, with one mismatch (5/6). When comparing allografts obtained from HLA identical (n=40) or(More)
Two main techniques are being used for the detection of minimal residual disease (MRD) in acute leukemia (AL): immunophenotypic analysis and polymerase chain reaction (PCR). In this paper, we analyze the results of assessing MRD by means of flow cytometry (FC) in a group of 93 patients with AL who were prospectively studied and treated in a single(More)
We have analyzed the transfusion requirements of a group of 132 peripheral blood stem cell transplants from a single institution (73 allografts and 59 autografts) over a 10-year period. The allografts were conducted using the 'Mexican' nonmyeloablative conditioning regimen, while the autografts were given single-day high-dose melphalan. For the allografts,(More)
