Genotipo cag A+ en cepas de Helicobacter pylori asociadas a úlcera péptica, gastritis crónica y cáncer gástrico
Martínez Echavarría,María Teresa; González Torres,Maximino; Ferreira Capote,Raúl; Mas Páez,Juan Antonio;
Revista Cubana de Medicina , 2008,
Abstract: abstract 171 patients with duodenal ulcer, gastric ulcer, chronic gastritis and gastric cancer were studied. the last 3 were histologically confirmed. 56 cases with duodenal ulcer, 48 with gastric ulcer, 47 with chronic gastritis and 20 with gastric cancer were analyzed. the presence of helicobacter pylori was detected by pcr in 98.2 % of the duodenal ulcers; in 95.8 % of the gastric ulcers; in 95.0 % of the gastric cancers; and in 93.6 % of the chronic gastritis. the cag a genotyping of the strains found proved to be positive in 80.0 % of the duodenal ulcers; in 72.7 % of the chronic gastritis; in 69.6 % of the gastric ulcers; and in 42.1 % of the gastric cancers, for a total prevalence of 70.7 %. both, the ulcers as a whole and the chronic gastritis showed a prevalence of cag a+ strains of helicobacter pylori significantly higher than gastric cancer (p = 0,19).

Abstract: Se estudiaron 171 pacientes con úlcera duodenal, úlcera gástrica, gastritis crónica y cáncer gástrico; los 3 últimos confirmados histológicamente. Se analizaron 56 casos con úlcera duodenal, 48 con úlcera gástrica, 47 con gastritis crónica y 20 con cáncer gástrico. Se detectó la presencia de Helicobacter pylori mediante PCR en el 98,2 % de las úlceras duodenales; en el 95,8 % de las úlceras gástricas; en el 95,0 % de los cánceres gástricos y en el 93,6 % de las gastritis crónicas, para una prevalencia total del 95,9 %. El genotipaje cag A de las cepas detectadas reportó positividad en el 80,0 % de las úlceras duodenales; en el 72,7 % de las gastritis crónicas; en el 69,6 % de las úlceras gástricas y en el 42,1 % de los cáncer gástricos, para una prevalencia total del 70,7 %. Tanto las úlceras en su conjunto, como la gastritis crónica presentaron una prevalencia de cepas Helicobacter pylori cag A+ significativamente superior al cáncer gástrico (p = 0,19).

Percepción de fenómenos tras la muerte por el personal sanitario en el hospital

Abstract: according to histories that count the sanitary personnel in the virgen del rocío hospital (seville), sometimes the welfare activity is interrupted by phenomenas, mainly in the context of the death of a patient, whom the physical laws do not give an explanation. these histories conform not only an own type of folklore, but that gets to condition the welfare work of some services, with a great emotional load of negative effects for the own personnel, being able to repel in the patient attention al. groups of 30 members of different hospitable areas chose themselves, with and without welfare activity, by means of the system of open interview investigated themselves in their experiences in this field, from which we created a data bank, but without leaving of side the human answer. it is to say: we have considered qualitative and quantitative aspects in this study. with this information we have investigated in the real experiences of the sanitary personnel with these phenomena to value that personal he is more susceptible to suffer them and that measured of performance they are possible to be taken.
Percepción de fenómenos tras la muerte por el personal sanitario en el hospital Perception of phenomena after the death by the sanitary personnel in the hospital

Abstract: Según las historias que cuentan el personal sanitario en el hospital Virgen del Rocío (Sevilla), a veces la actividad asistencial es interrumpida por fenómenos, sobre todo en el contexto de la muerte de un paciente, a los que las leyes físicas no dan una explicación. Estas historias conforman no sólo un tipo de folclore propio, sino que llega a condicionar la labor asistencial de algunos servicios, con una gran carga emocional de efectos negativos para el propio personal, pudiendo repercutir en la atención al paciente. Se escogieron 30 profesionales de diferentes áreas hospitalarias, con y sin actividad asistencial, mediante el sistema de entrevista abierta se indagó en sus experiencias en este campo, a partir de las cuales creamos un banco de datos, pero sin dejar de lado la respuesta humana. Es decir: hemos tenido en cuenta aspectos cualitativos y cuantitativos en este estudio. Con esta información hemos indagado en las experiencias reales del personal sanitario con estos fenómenos para valorar qué personal es más susceptible de padecerlos y qué medidas de actuación se pueden tomar.

Revista chilena de pediatría , 1999,
Abstract: La panencefalitis esclerosante subaguda postsarampión (PEES) es en la actualidad una entidad infrecuente en aquellos países donde existen programas regulares de vacunación contra el sarampión. Presentamos un caso, con evolución rápida a la muerte, en el cual fueron observados los hallazgos característicos. Entre los más relevantes: títulos elevados de anticuerpos antisarampión en el líquido cefalorraquídeo (LCR), patrón periódico en el EEG, fenómenos de desmielinización progresiva en el scanner y resonancia nuclear magnética cerebral, asociados a la presencia constante de crisis mioclónicas. A pesar de una terapia continua con alfa-interferón intratecal, cimetidina en dosis inmunorreguladoras y un antiviral, se observó un deterioro progresivo del paciente. El estudio neuropatológico reveló compromiso a nivel de los centros semiovales de los hemisferios frontales, de predominio izquierdo SSPE is an infrequent disease in countries with regular vaccination programmes. We present a case, its evolution and post mortem studies in which characteristic findings of SSPE were observed. The most relevant findings were: elevated measles antibodies in the CSF, a periodic discharge pattern in the EEG, changes of progressive demyelinization in the brain demonstrated by CT and MRI studies, associated with the constant presence of myoclonic seizures. Inspite of con-tinued therapy with intrathecal alpha-interferon, an immunoregulatory dose of cimetidine and an antiviral agent a progressive deterioration was observed. Neuropathological study demonstrated a significant deterioration at the level of the semioval centres of the frontal hemispheres, especially the left
An electrochemical study of tin oxide thin film in borate buffer solutions
Díaz Raül,ez-Pérez Ismael,Gorostiza Pau,Sanz Fausto
Journal of the Brazilian Chemical Society , 2003,
Abstract: The electrochemical behavior of tin polycrystals in borate buffer solutions at pH 7.5 was systematically investigated using cyclic voltammetry, EC-STM and electrochemical impedance measurements. A systematic shift to more negative values of the potentials corresponding either to the major reduction peak either to the hydrogen evolution was measured when the anodization potential used for film growth was increased. A discussion about the different oxides there formed was included and a reassignation of tin oxidation and tin oxides reduction processes was given.

Mathematics , 2006,
Abstract: We study the palindromic complexity of infinite words $u_\beta$, the fixed points of the substitution over a binary alphabet, $\phi(0)=0^a1$, $\phi(1)=0^b1$, with $a-1\geq b\geq 1$, which are canonically associated with quadratic non-simple Parry numbers $\beta$.
