Estudio comparativo de la amplificación de Her2/neu mediante FISH y PCR cuantitativa en tiempo real en tumores de mama
Cabrera Morales,C. M.;
Oncología (Barcelona) , 2005, DOI: 10.4321/S0378-48352005001000003
Abstract: the her2/neu protooncogene is amplified or over-expressed in 20 to 30% of breast tumors and its determination is important to evaluate the susceptible patients to be treated with trastuzumab. we compare in this study the fish and real-time quantitative pcr techniques in the determination of her2/neu amplification of 40 breast tumors. the fish procedure showed 21 fish-positive and 19 fish-negative tumors. these results proved to have a good concordance with the pcr technique, that was of 100% for the fish-negative and 80.95% for the fish-positive breast tumors. therefore, the real-time quantitative pcr represents a useful technique for establishing the her2/neu status in breast cancer.
Tumor desmoplásico de células peque?as y redondas (DSRCT) de ri?ón
Cabrera Morales,C. M.;
Oncología (Barcelona) , 2005, DOI: 10.4321/S0378-48352005000500005
Abstract: desmoplastic small round cell tumor is a rare disease consisting of a form of peritoneal surface malignancy usually affecting young males, composed of relatively small and undifferentiated cells with a high nuclear-cytoplasmic ratio. the co-expression of epithelial, muscular and neuronal antigens distinguishes this entity from other small round cell tumors. the t(11;22)(p13;q12) translocation is a recurrent characteristic of this type of tumor. however, we report a new case of desmoplastic small round cell tumor of the kidney affecting a 20 year old male where the t(11;22)(p13;q12) is absent.

Abstract: Objective: To determine the associated factors for in-hospital mortality in patients with meningeal cryptococcosis and HIV infection at a local hospital in Lima, Perú. Materials and methods: We carried out a case-control study by reviewing the medical histories available at a local hospital in Lima, Peru. We determined the factors associated with mortality using a logistic regression model. Results: The information of 90 patients was analyzed, 37 dead and 53 alive. In the multivariate analysis we found two variables associated with mortality: Glasgow at admission (OR = 4.55 (1.61 – 12.20), p = 0.01) and serum antigen titer greater than 1024 (OR = 20.48 (1.6 – 261.04, p = 0.02). The protective factor found was a longer hospitalization stay (OR = 0.80 (0.69 – 0.93, p = 0.005).Conclusions: A low Glasgow score and serum antigen titer greater than 1024 are associated factors with mortality, whereas hospitalization length is a protective factor.

Journal of the Chilean Chemical Society , 2003, DOI: 10.4067/S0717-97072003000100002
Abstract: chitosan, was obtained from red lobster shells (pleuroncodes monodon). the mv of chitosan prepared was 54.000 g/mol with a deacetylation degree of 20%. the retention capacity of chitosan for copper and mercury ions was studied. the adsorption isotherms of cu(ii) and hg(ii) and the mixture of ions are discussed using the langmuir and freundlich model. the selectivity from the mixture of both ions was measured. the ph effect on retention was tested. furthermore, the uptake of both ions in a mixture was compared using chitosan and a commercial resin amberlite ira-68
Cistinuria: diagnóstico y aproximación terapéutica
Cabrera-Morales,C.M.;
Anales del Sistema Sanitario de Navarra , 2011, DOI: 10.4321/S1137-66272011000300011
Abstract: cystinuria is an aminoaciduria due to the impairment of transport of cystine and dibasic amino acids (arginine, ornithine, and lysine) in the apical membrane of the intestinal epithelium and proximal renal tubule. the result is an absence of cystine reabsorption in the renal tubule producing an excess of cystine in urine and stone formation. unlike the other stones, cystine stones are very difficult to eliminate with lithotripsy. noninvasive therapy should therefore be used to prevent relapse in stone formation. this therapy is based on the use of high fluid intake, urine alkalinization, and chelating agents. in order to preserve renal function, a combination of these three therapeutic measures is necessary to produce a low recurrence and morbidity of the disease.
Los tóxicos ambientales y su impacto en la salud de los ni?os
Zayas Mujica,Roberto; Cabrera Cárdenas,Ulises;
Revista Cubana de Pediatr?-a , 2007,
Abstract: the relationship between human beings and the environment has changed from ancient times to the present, being more critical since the second half of the 20th century. children are the most vulnerable group due to their anatomic and physiological immaturity and psychosocial dependence. air and water pollution, chemical emissions, ozone depletion and the consequences of climate change are the main problems related to it. pediatricians should be duly informed about it because children have special sensitivity, vulnerability and, in some cases, timely recovery capability in the face of the action by different environmental toxics. we intended to review in a number of databases the most recent statements on the effects of various environmental pollutants that threaten health and future development of children.
Anemia aplástica adquirida del adulto: Su tratamiento a propósito de dos casos

Revista médica de Chile , 2003, DOI: 10.4067/S0034-98872003001200012
Abstract: severe aplastic anemia has an elevated mortality if treatment is unsatisfactory. immunosuppression is the treatment of choice in adults, comparable with allogeneic bone marrow transplant in children. we report two adult patients (both males, aged 59 and 67 years old) who were treated successfully with lymphoglobulin and cyclosporine. the initial response started within 3 months of treatment and was almost complete after 2 years, when cyclosporine was stopped. after three years, both patients have almost normal blood counts, with minor sequels: avascular necrosis of both femoral heads due to the use steroids, that recovered spontaneously in 1 patient and reduced vision due to thrombocytopenic retinal hemorrhages, in the other (rev méd chile 2003; 131: 1439-43).
Los tóxicos ambientales y su impacto en la salud de los ni os Environmental toxics and their impact on the child′s health

Abstract: La relación entre los seres humanos y el ambiente ha variado desde los tiempos remotos hasta la actualidad, y se ha hecho crítica a partir de la segunda mitad del siglo XX. La ni ez es el grupo más vulnerable, a causa de su inmadurez anatomofisiológica y su dependencia psicosocial. La contaminación del aire y del agua, las emisiones químicas, el agotamiento del ozono y las consecuencias del cambio climático son los principales problemas relacionados con la salud. Los pediatras deben estar plenamente informados al respecto, puesto que los ni os tienen una especial sensibilidad, vulnerabilidad y, en algunos casos, una oportuna capacidad de recuperación ante la acción de diferentes tóxicos ambientales. Nos propusimos revisar en diferentes bases de datos los planteamientos más recientes sobre los efectos de diferentes contaminantes ambientales que amenazan la salud y el desarrollo futuro de los ni os.
