Se analizan 80 pacientes con cuadros sugestivos del síndrome antifosfolipídico. Todos los pacientes estuvieron comprendidos entre 20 y 40 años de edad, 13 (16%) casos mostraron alguna prueba positiva del citado síndrome, cinco de ellos, 4 mujeres y 1 varón presentaron anticoagulantes lúpico positivo y 8 casos, 6 mujeres y 2 varones evidenciaron anticuerpos anticardiolipina positivos. A los 13 pacientes se les realizó el dímero D por dos métodos, así como, los niveles de fibrinógeno y la presencia de productos de degradación del fibrinógeno (PDF). Los métodos de dímero D que se utilizaron fueron: la técnica de aglutinación indirecta con partículas de látex y la técnica de ELISA. Los resultados obtenidos muestran que los pacientes con anticoagulante lípico y /o anticuerpos anticardiolipina positivos y que presentan dímero D, muestran un cuadro de oclusión venosa que puede contribuir a la génesis de su problema trombótico.</p></abstract>
<abstract abstract-type="short" xml:lang="en"><p>The determination of Dimer-D has a great value establishing the diagnosis of deep venous thrombosis. However, in patients that present lupic anticoagulant, its importance and discovery are still not well defined. Because of these reasons, an investigation was planned to evaluate its presence in 80 patients with descriptions suggesting the antiphospholipid syndrome. All patients were aged 20 and 40 years. From the total sample estudied only 13 cases (16%), showed a positive test for the mentioned syndrome. Five cases (1 man and 4 women) had positive lupic anticoagulant and 8 cases (2 men and 6 women) had positive the anticardiolipin antibodies. To the whole group of 13 patients the dermination of Dimer-D was made by 2 different methods. The levels of fibrinogen and the presence of the fibrinogen degradation products were also realized. The methods used to determine Dimer-D were: indirect agglutination with latex particles, and an Elisa test. The results obtained show that the patients with a positive lupic anticoagulant and/or a positive anticardiolipin antibodies, together with the presence of Dimer-D, describes cases with venous oclussion wich contributes to the genesis of the trombotic problem.</p></abstract>

Se tomaron medidas antropométricas, bioquímicas e inmunológicas semanalmente por un lapso máximo de tres semanas consecutivas. También se calcularon los requerimientos de macronutrientes de cada paciente y se compararon con las cantidades suministradas por las fórmulas de soporte nutricional prescritas por el personal médico responsable. Al inicio del estudio la evaluación nutricional demostró que el 100% del grupo presentaba desnutrición de acuerdo con los valores del pliegue tricipital y cerca de un 60%, según la circunferencia muscular del brazo y los valores de albúmina y de proteínas totales. Al término del estudio no se comprobaron cambios notables en el estado nutricional inicial del grupo, que mantuvo deficientes los valores de hemoglobina y hematocrito en la mayoría de los casos. Los carbohidratos representaron en un 60% el mayor aporte energético de las fórmulas de soporte nutricional ; las proteínas, en un 15% y los lípidos, un promedio de 25% del valor energético total. Sin embargo, en más de la mitad del grupo (59%), no se alcanzó a cubrir sus necesidades energéticas ; ni tampoco las de proteínas en la totalidad de esos pacientes. Se concluye que es necesario realizar un cálculo nutricional individualizado y de monitorear la evolución del paciente por un equipo de salud que incluya un nutricionista a fin de evitar la sobre o subestimación del aporte de energía y macronutrientes en las fórmulas de nutrición parenteral total suministradas a este tipo de pacientes.</p></abstract>
<abstract abstract-type="short" xml:lang="en"><p>The aim of this article was toassess the anthropometric status as well as the biochemical and inmunological condition of 32 adult patients receiving total parenteral nutrition formulae at San Juan de Dios Hospital. The patients were fed with these formulae during three weeks at least. At the begining of the study, all the patients presented malnutrition as was evaluated by triceps skinfold and 60% when it was evaluated by arm muscle circumference, serum albumin and total protein. At the end of the study, no positive changes were found in the nutrition status of the patients. The energy requeriments and the macronutrient intake of each patient were estimated and compared with the enrgy and the macrocutrient content of the parenteral nutrition formulae prescribed by the physician. Carbohidrates accounted for 60% of the total energy value of the formulae ; proteins, 15% and lipids, 25%. However, in more than half of the patients (59%), energy and protein requirements were not satisfied. In summary, it is necessary to adapt the parenteral nutrition diet to the individual requirements of each patient. Also, patients should be controlled by a skilled health team, including a nutritionist, in order to avoid errors in estimation of energy and macronutrient requirements.</p></abstract>

Se determinaron las concentraciones plasmáticas (Cp) en muestras extraídas a los siguientes tiempos: 0, 0,5, 1, 1.5, 2, 3, 4, 6, 7, 9, 10, 12, 24 y 48 horas. La concentración máxima (C MAX) fue de 11,73± 2.55 ng/mL y la mayoría de los tiempos para C MAX (tMAX) oscilaron entre 1 y 1.5 h. El tiempo de vida media (t½) de eliminación fue de 14,21 ± 5,72 h y el área bajo la curva 0 a 48 h (ABC0-48) alcanzó una magnitud de 135,16±62,89 ng/mL- h. Los perfiles de las Cp fueron equivalentes y los diferentes parámetros evaluados no se diferenciaron en función del sexo. Todos los sujetos mostraron una buena tolerabilidad al fármaco. Con este ensayo se concluye que no hay evidencia de diferenciación en la farmacocinética del ALZ debida al factor sexo y que la realización de este tipo de ensayos contribuye a describir la posible existencia de diferencias cinéticas atribuibles al sexo.</p></abstract>
<abstract abstract-type="short" xml:lang="en"><p>To evaluate the possible influence of gender in the pharmacokinetic behavior of benzodiazepines, a single oral dose of alprazolam 1 mg was administered to 8 men and 8 women, all healthy subjects. Samples for plasmatic concentrations (Cp) were extracted at the following times: 0, 0,5, 1, 1,5, 2, 4, 6, 7, 9, 10, 12, 24 y 48 hours. The maximum plasma drug concentration (Cmax) was 11,73±2,55 ng/mL and the time to reach peax concentration (t max) varied betwen + 1 y +1,5 hs. The elimination half-life (t½) was 14,21 ±5,72 h and the area under the concentration-time curve 0 to 48 hs (AUC0-48) reached a magnitude of 135,16±62,89 ng/mL-; h. Similar profiles of Cp were found and kinetic parameters were equivalent in both sexes. We also found a good tolerance to the drug in all subjects. In this assay, we conclude that the results do not suggest kinetic diferences by sex after ALZ ; however, other assays like this help to describe whether kinetics differences really can be gender related.</p></abstract>

Se encontró un 1,08% de personas positivas para Diª y un 98.02% de negativas para ese factor. Lo anterior corresponde con una frecuencia fenotípica de 0.003% para Di (a+b-), de 1,074% para Di (a+b+) y de 98,923% para Di (a-b+). Esto a su vez implica una frecuencia alélica de 0.0054 para Diª y de 0.9946 para Di b. La distribución observada nos indica que este sistema tiene en Costa Rica muy poca importancia clínica y médico-legal debido a la prevalencia polarizada de sus alelos , cosa que no es extraña en una población con ascendencia mongoloide relativamente escasa.</p></abstract>
<abstract abstract-type="short" xml:lang="en"><p>For the investigation of the phenotypes, genotypes and genes distribution of the Diego system, we analized 554 blood samples of individuals from all country provinces. The study revealed that 1.08% was positive for Dia and 98.92% was negative for this factor. This value correspons to a phenotypical frecuency of 0.003% for Di (a+b-), 1.074% for Di (a+b+) and 98.923% for Di (a-b+). This implies an allelic frecuency of 0.0054 for Diª. and 0.9946 for Di b. . This distribution indicates that this system has litle clinical and forensic significance in Costa Rica because of the polarized prevalence of this alleles. These findings are not unexpected in a population with a scant mongoloid extration.</p></abstract>

No obstante, hoy se discute nuevamente sobre el potencial patogénico de esta bacteria, y en esta ocasión se relaciona con el cáncer gástrico. Entre las pruebas que fundamentan esta hipótesis está la evidencia serológica de una infección previa con H. pylori en pacientes con cáncer gástrico, y la remisión de algunos linfomas gástricos al tratamiento con antibióticos. Por otra parte, se asocia esta bacteria con la causalidad de algunos de los cuadros de dispepsias no ulcerativas, aunque lo subjetivo de los síntomas en esta condición clínica hace difícil su diagnóstico.</p></abstract>
<abstract abstract-type="short" xml:lang="en"><p>After some years of discussion Helicobacterp pyloriis accepted has been accepted eas the etiologic agent of type B gastritis and peptic ulcers. Thus, these pathological entities could be treated with antibiotics. However, the discussions still persist about the possible relation between H. pylori and gastric cancer. This hypothesis is based on documented serologic evidence of previous infection with this bacteria and the increase the risk for gastric cancer, as wellas reports showing remission of some gastric lymphomas with anti H. pilori treatment. H. pylori has also been indicated as the causative agent of non-ulcerative dyspepsia, but the nature of this disease inders the early diagnosis and the possible linkage with Helicobacter, Nevertheless, the wide spectrum of polimorphic manifestations on this infectious agent increase the importance of new knowledge of this topic.</p></abstract>
