ABSTRACT

Resumen Objetivo: Mostrar los resultados en el corto y mediano plazo del tratamiento endovascular de angioplastia transluminal percutánea (ATP) con balón en pacientes en estado de isquemia crítica por enfermedad arterial obstructiva infrapoplítea. Materiales y Método: Estudio descriptivo, observacional, retrospectivo. Se incluyeron los pacientes hospitalizados entre 2009 y 2018 por isquemia crítica Fontaine III o IV sometidos a una ATP del territorio infrapoplíteo. Se observó como objetivos primarios la preservación de la extremidad afectada y la mortalidad posoperatoria a un año plazo, y como objetivos secundarios los procedimientos adicionales en pacientes con lesiones o necrosis distales, estadía hospitalaria, complicaciones posoperatorias y necesidad de reintervención. Resultados: Se incluyeron 42 pacientes con un promedio de edad de 66 años (46-82), con importantes comorbilidades. Un 83,3% ingresó en etapa Fontaine IV. En 16 casos se realizó una angioplastia percutánea en más de una arteria. No se colocó stents. Se presentaron complicaciones en 3 pacientes, 2 requirieron una amputación mayor y en otro se debió efectuar un nuevo procedimiento endovascular de rescate. La estadía hospitalaria promedio fue 22 días. No hubo mortalidad precoz posprocedimiento. La mortalidad global a un año fue 9,5%. A todos los pacientes en etapa Fontaine IV se les efectuó algún procedimiento adicional, a 31 una amputación menor, 3 cerraron sus lesiones por segunda intención y en otro se realizó un injerto dermo-epidérmico. De los 35 pacientes con seguimiento, 77% preservó su extremidad a un año. Conclusión: La reparación endovascular mediante una angioplastia percutánea en estos casos es un procedimiento seguro y tiene una alta tasa de preservación de la extremidad inicial a un año de seguimiento.


Aim: Show initial and midterms results of endovascular Percutaneous Transluminal Angioplasty (PTA) in critical limb isquemia (CLI) patients caused by below-the-knee arterial disease. Materials and Method: Observational, descriptive and retrospective study. 42 CLI patients admitted in our hospital from 2009 until 2018 with Fontaine III or IV treated by PTA in infrapopliteal arteries were analyzed, collecting demographic, clinical and surgical characteristics, additional procedures in Fontaine IV, hospital stay, postoperative complications, need of reintervention, limb preservation and mortality with one year follow-up after procedure. Results: 42 patients, average age 66 year-old (46-82), with significant comorbidities. Fontaine IV stage patients were 83.3%. In 16 cases more than one artery was intervened. No stent revascularization was performed. Complications occurred in 3 patients, 2 required major amputation and an urgent endovascular reintervention was required in another. Average hospital stay was 22 days with no post-operative mortality. One-year global mortality was 9.5 One-year follow-up in 35 patients shows that 77% preserved their limb. Conclusión: Percutaneous transluminal angioplasty procedure in this patients has a high rate of limb preservation in a one-year follow-up. There was no post-operative mortality.

ABSTRACT

El tratamiento de la Enfermedad Metastásica Cerebral única es paliativo y multimodal desconociéndose con certeza la modalidad o combinación terapéutica óptima. Se planteó como objetivo determinar las diferencias entre la Radioterapia Holocraneal, Radiocirugía, y Resección Quirúrgica en cuanto a la Sobrevida Global, Sobrevida Con Independencia Funcional, Control Local, Muerte Neurológica y Neurocognición en los pacientes con enfermedad metastásica cerebral única con tumor primario controlado. Se realizó un estudio retrospectivo del tipo revisión sistemática cualitativa. Se incluyeron Ensayos Clínicos Aleatorizados que compararon la Cirugía (con o sin Radioterapia Holocraneal), con la Radiocirugía (con o sin Radioterapia Holocraneal) en la Enfermedad Metastásica Cerebral Única independientemente de la localización del tumor primario. La búsqueda encontró inicialmente 971 artículos, de ellos 19 Ensayos Clínicos Aleatorizados. Al aplicar la herramienta de riesgo de sesgos de Cochrane se derivó una muestra de 14 Ensayos Clínicos que presentaron bajo riesgo de sesgos. La combinación de RQ y RTH ofreció mayor SG que la RTH sola. La combinación de RTH y RC ofreció un mejor CL que la RQ y RTH. La combinación de RTH Y RC ofreció un mejor CL y SG que la RTH sola. No se encontraron diferencias significativas entre la RTH y RC versus RC sola. Los resultados en cuanto a la neurocognición y SIF fueron inconsistentes. El tratamiento óptimo de los pacientes con EMC aún no está bien definido constituyendo aún un tema controvertido.


The treatment of Isolated Cerebral Metastatic Disease is both multimodal and palliative. At present, the optimal treatment protocol is unknown. The objective of the present study was to determine outcome differences between Whole Brain Radiotherapy (WBRT), Radiosurgery (RS), and Surgical Resection (SR) or a combination of them, regarding Global Survival, Functional Independent Survival, Local Control, Neurological Death & Cognitive Status in patients with a unique cerebral metastasis and a controlled primary tumor. A retrospective study with a systematic qualitative literature review was performed. Randomized clinical trials comparing surgery (with or without whole brain radiotherapy), disregarding the localization of the primary tumor, were searched, resulting in 971 studies, only 19 of them being randomized. After applying Cochrane´s Risk of Bias Tool, only 14 studies showed a low risk of bias. The combination of SR & WBRT showed a longer survival, while WBRT & RS showed a better local control when compared with SR & WBRT. No statistical differences where found between WBRT & RS versus RS alone. Results regarding Cognitive Status & Functional Independent Survival were inconsistent. The optimal treatment in Isolated Metastatic Cerebral Disease still remains controversial.

ABSTRACT

El control del Aedes aegypti (vector principal del Dengue), se dificulta por la extensión y heterogeneidad de los barrios donde se encuentran los criaderos, la carencia de acceso permanente a servicios públicos y por la ausencia de vigilancia epidemiológica estricta y constante. Se registraron 2.603 casos de dengue confirmados por IgM-dengue, durante el período 1995-2010. El estudio se realizó en Puerto Ayacucho, capital del estado Amazonas con 98.824 habitantes. Los casos confirmados se agruparon de acuerdo con la localización de su residencia. La información se representó espacialmente para analizar los patrones espacio-temporales del dengue, estableciéndose una estratificación de la ciudad. La prevalencia de dengue mostró una correlación positiva con la persistencia por barrio, lo que permitió agruparlos en dos clases: (1) alta prevalencia y persistencia, con 66% de los casos confirmados, y (2) baja prevalencia y persistencia, con 34% de los casos. Se demuestra que en Puerto Ayacucho existen “focos calientes” o de mayor transmisión y “focos fríos” o de transmisión transitoria. En conjunto, los barrios incluidos en la categoría de alta prevalencia y persistencia representan 65,1% del área urbana. Este es el espacio geográfico en el cual recomendamos concentrar los esfuerzos de control. La estratificación de la ciudad e identificación de los barrios productores de casos, mostrando las áreas donde es más probable la transmisión del virus, permitirá concentrar los esfuerzos para mitigarla. El enfoque de las actividades de control basado en una estratificación, permite dirigir los programas hacia áreas más problemáticas.


Control of Aedes aegypti is difficult to perform due to the extent and variety of neighborhoods where the breeding grounds are found, the lack of permanent access to public services, and to the absence of a strict and constant epidemiological surveillance. 2,603 confirmed dengue cases (IgM-dengue) were recorded during the 1995-2010 period. This study was carried out in Puerto Ayacucho, main city of Amazonas State, Venezuela, with 98,824 inhabitants. Confirmed cases of individuals affected were grouped according to the location of their residence. Information is spatially represented to analyze space-time patterns of dengue, establishing a stratification of the city. The prevalence of dengue showed a positive correlation with the persistence per neighborhood, allowing to group the neighborhoods into two classes: (1) High prevalence and persistence, with 66% of the confirmed cases, and (2) low prevalence and persistence, with 34% cases. The study shows there are "hot spots" or higher transmission areas, and "cold spots" or transient transmission areas in Puerto Ayacucho. All the neighborhoods included in the category of high prevalence and persistence represent 65.1% of the urban area. This is the geographical area in which we recommend to concentrate control efforts. The stratification of the city and the identification of case-producing neighborhoods, showing the areas where virus transmission is most likely, will permit concentrating efforts to mitigate it. Focus of control activities based on a stratification study allows directing programs to most problematic areas.

ABSTRACT

Antecedentes: El antígeno leucocitario humano (HLA)-G es una molécula inmunomoduladora que contribuye a la aceptación del feto semialogénico. Algunos polimorfismos de un solo nucleótido (SNP) en las regiones no codificantes del gen HLA-G inducen a la disminución de moléculas HLA-G, lo cual contribuye a complicaciones en el embarazo, tales como la preeclampsia o pérdida gestacional recurrente. Objetivo: Analizar la asociación de los polimorfismos -725C>G (rs1233334), -201G>A (rs1233333) y 14 bp deleción/inserción (14-pb del/ins) (rs66554220) del gen HLA-G en mujeres mexicanas con PGR. Métodos: Los polimorfismos -725C>G (rs1233334), -201G>A (rs1233333) y 14-pb del/ins (rs66554220) se identificaron por medio de PCR-SSOP (Polymerase Chain Reaction-sequence-specific oligonucleotide probe) y PCR (Polymerase Chain Reaction), respectivamente, en 58 mujeres con pérdida gestacional recurrente (> 2 abortos), sin factores de riesgo identificables y 56 mujeres fértiles no relacionadas (> 2 nacidos vivos). Resultados: El polimorfismo -725C>G (rs1233334) presentó diferencias significativas entre los grupos de estudio pero no se asoció con PGR (p=0,02601; OR=11,484; IC95 por ciento =0,617-213,659). Los polimorfismos -201G>A (rs1233333) y 14-pb del/ins (rs66554220) no se distribuyeron de manera diferente entre los grupos de estudio ni se asociaron con pérdida gestacional recurrente. Los polimorfismos analizados se encontraron en equilibrio de ligamiento (D'>0,3563; r²<0,1140). Conclusión. Este estudio sugiere que los polimorfismos -725C>G (rs1233334), -201G>A (rs1233333) y 14-pb del/ins (rs66554220) del gen HLA-G están en equilibrio de ligamiento y no influyen en el riesgo de pérdida gestacional recurrente en mujeres mexicanas.


Background: The human leukocyte antigen (HLA)-G is an important immunomodulatory molecule that contributes to the acceptance of the semi-allogeneic fetus. Some single nucleotide polymorphisms (SNP) in the noncoding regions of the HLA-G gene may influence the cellular levels of HLA-G, contributing to pregnancy complications such as preeclampsia or recurrent pregnancy loss. Objective: To analyze the association of -725C>G (rs1233334),-201G>A (rs1233333) and 14 bp deletion/insertion (14-bp del/ins) (rs66554220) polymorphisms in the HLA-G gene in Mexican women with RPL. Methods: -725C>G (rs1233334), -201G>A (rs1233333) and 14-bp del/ins (rs66554220) polymorphisms in the HLA-G gene were identified by PCR-SSOP (polymerase chain reaction-sequence-specific oligonucleotide probe) and PCR (polymerase chain reaction), respectively, in 58 women with recurrent pregnancy loss (> 2 miscarriages) without identifiable risk factors and 56 unrelated fertile women (> 2 live births). Results: -725C>G (rs1233334) polymorphism showed significant differences between the study groups but it was not associated with recurrent pregnancy loss (p=0.02601, OR=11.484; 95 percent CI=0.617-213.659). -201G>A (rs1233333) and 14-bp del/ins (rs66554220) polymorphisms were not distributed differently in study groups and not associated with RPL. Analyzed polymorphisms were in linkage disequilibrium (D' > 0.3563, r² < 0.1140). Conclusion: This study suggests that -725C>G (rs1233334), -201G>A (rs1233333) and 14-pb del/ins (rs66554220) in the HLA-G gene are in linkage equilibrium and do not influence the risk of recurrent pregnancy loss in Mexican women.

ABSTRACT

Three varieties of cassava bread were analyzed by proximal analysis and biochemical methods. The content of protein, fat, carbohydrate, ash, crude fiber and dietary fiber (DF) differed significantly between each sample (p< 0.05). The cassava variety "Puerto Ayacucho" showed a higher content of insoluble DF (4.7%), soluble DF (1.6%), total DF (6.3%) and pectin (0.61%)) in comparison with the varieties of "Rio Chico" and "Caripito". Soluble DF retains significant amounts of water in the digestive tract, and this fact, combined with its reported effect of lowering human serum cholesterol its low moisture plus a high carbohydrate content confirm the suitability of this bread as an important nutritional food.


Tres variedades de casabe de yuca fueron analizados mediante el análisis proximal y métodos bioquímicos. El contenido de proteínas, grasas, hidratos de carbono, ceniza, fibra cruda y fibra dietética (FD) difieren significativamente entre cada muestra (p <0,05). La variedad de casabe "Puerto Ayacucho" mostró un mayor contenido de FD insoluble (4,7%), FD soluble (1,6%), FD total (6,3%) y pectina (0,61%)) en comparación con las variedades de "Rió Chico" y "Caripito ". FD soluble retiene grandes cantidades de agua en el tracto digestivo, y este hecho, combinado con su efecto ya reportado de bajar el colesterol del suero humano, así como el casabe de contener un bajo contenido de humedad aunado a un alto contenido de hidratos de carbono; confirma la idoneidad del mismo, como un importante alimento nutricional.

ABSTRACT

El dengue se ha ido incrementando significativamente en la región de las Américas e islas del Caribe en las últimas dos décadas. Venezuela ha presentado las mayores tasas de incidencia de DH y el mayor número de fallecidos. En el estado Amazonas se reportan los primeros casos de dengue en el año 1995, siendo el municipio Atures el más afectado. El presente trabajo describe el comportamiento del dengue en el estado Amazonas durante los años 1995 al 2008, mediante la revisión de los registros epidemiológicos y análisis de serotipos del virus DENV. Durante el período 1995-2008 se registró un total de 6209 casos de dengue y 27 con DH, con tres epidemias, quedando demostrada la circulación de los 4 serotipos. Durante las 3 epidemias se hospitalizaron 94 pacientes con Dengue y solo 12 con diagnóstico de DH de 33 con criterios para DH según OPS. En 1995 se registraron 546 casos de dengue, con un solo deceso reportado. La prevalencia anual del Dengue disminuyó en los años 1996-2000 de manera significativa con respecto al año de la epidemia para nuevamente ascender en el año 2001 a cifras de positividad superiores a las del año 1995. Desde el 2003 hasta la fecha el número de casos ha ido en ascenso con presencia significativa de casos de DH. Es necesario que a nivel de la Dirección Regional se estructure un Plan de Control a fin de mantener un Sistema activo de Vigilancia y se revisen periódicamente las pautas de criterios para definir DH.


Dengue fever (DF) has been significantly increasing in the Americas and the Caribbean islands over the past two decades. Venezuela has presented the highest incidence of dengue hemorrhagic fever (DHF) and the largest number of deaths. In Amazonas state the first cases of dengue were reported in 1995, being Atures the most affected municipality. This paper describes the behavior of dengue in the Ama zonas state in the years 1995 to 2008, by reviewing records and epidemiological analysis of DENV virus serotypes. In that period a total of 6209 dengue cases and 27 DHF cases was reported, with three epidemics, proving the movement of the 4 serotypes. During the epidemics 94 pa - tients with dengue were hospitalized, and only 12 were diag nosed with DHF of 33 with PAHO criteria. In 1995 there were 546 dengue cases with one death registered. The an - nual prevalence of dengue significantly declined in the years 1996-2000 compared to the year of the epidemic, but it rose again in 2001 to positive figures higher than 1995. From 2003 until today the number of cases has been increasing with a significant presence of DHF cases. Therefore, it is necessary that in the Regional Health Division a control plan be structured in order to maintain a Monitoring System and periodic reviews of guidelines defining criteria for DHF.

ABSTRACT

La fibra dietética o alimentaría es un término genérico que cubre una amplia variedad de sustancias químicas, con diferentes propiedades y efectos fisiológicos. Química mente, la fibra dietética es una sustancia perteneciente a la familia de los carbohidratos. En los últimos 40 años, ha tenido un creciente interés en el campo de la salud y nutrición humana. En general, la fibra alimentaría la encontramos en los productos alimenticios de origen vegetal. Un buen ejemplo de ello son las leguminosas de grano. Las leguminosas, a través de la historia, siempre han sido un recurso alimenticio de gran importancia para la alimentación humana. Representan, por un lado, una fuente barata de proteínas y, por el otro, un suministro de fibra dietética a la dieta. El presente artículo, fue enfocado a revisar y recopilar los mayores trabajos realizados sobre la determinación y cuantificación de la fibra alimentaría en algunos alimentos, principalmente en leguminosas venezolanas.


The dietary fiber or alimentary fiber, it is a generic term which covers a wide variety of chemical substances, with different properties and physiological effects. Chemically, the dietary fiber is a substance belonging to the family of the carbohydrates. In the last 40 years it has had increasing interest in the field of health and human nutrition. In general, we find the alimentary fiber in the food products from vegetable. A good example of it, are the legume seeds. The legume seeds across the history, have been a food resource of great importance for human nutrition. On the one hand, a cheap source of proteins and on the other one, an additional supply of fiber to the diet. The present article, was focused to review and to collect the most realised works for the determination and quantification of alimentary fiber in of the mainly Venezuelan legumes seeds.

ABSTRACT

En la presente revisión se describe la neocitolisis, un proceso de hemólisis selectiva para eritrocitos jóvenes, evidenciada en pacientes con insuficiencia renal crónica al suspenderles el tratamiento con eritropoyetina recombinante y documentada igualmente en astronautas al entrar en contacto con la microgravedad y en personas aclimatadas a gran altitud, luego de descender a nivel del mar. Se discute también el modelo postulado hasta el momento para demostrar la hemólisis selectiva "in vivo", que permite establecer para la eritropoyetina la nueva función de factor trófico en la maduración plasmática eritroide y se comentan los escenarios clínicos y las aplicaciones hacia el futuro de este proceso...


The present revision describes Neocytolysis, a process of selective hemolysis of young erythrocytes, demonstrated in patients with chronic renal insufficiency when suspended from treatment with recombinant erythropoietin and documented, also, in astronauts when entering in contact with microgravity and in people acclimated to great altitude, when they descend to sea level. The model postulated until now to demonstrate selective hemolysis "in vivo" is also discussed, which allows to establish the new function of trophic factor for erythropoietin in the plasmatic erythroid maturation and comments are made on the clinical scenarios and the applications towards the future of this process...

ABSTRACT

In Chile, the first cases of AIDS were reported 23 years ago, and since then, through December 2006, 17.235 persons have been notified with HIV infection or AIDS¹. To the year 2005, there have been 5.288 fatal cases of AIDS. The last available data indicates that notification rates for AIDS and HIV infection in 2006 were 2.5 and 4.5 per 100.000 inhabitants, respectively, and mortality rate for AIDS in 2005 was 2.4 per 100.000 inhabitants. Trend analysis shows a decline in the notification rate among men, both for HIV infection and AIDS, which could be a real decrease or a sub notification bias. In Chile, like in other countries of the region, variations in the epidemiologic pattern were observed considering age group, gender, educational level and geographic distribution of the population. Currently, the Chilean Ministry of Health has implemented both a surveillance and monitoring system on line, in order to improve the quality and opportunity of the information, therefore providing an important tool to HIV infection/AIDS prevention and control strategies.

ABSTRACT

El crecimiento reciente de infecciones por hongos dermatiácenos y el indiscriminado uso de drogas antifúngicas, motivaron la preparación y estandarización de un producto que cumpla con las normas NCCLS, siguiendo el protocolo M-38P, que garantice un método reproducible, eficaz y sencillo para las pruebas de sensibilidad in vitro. Se obtuvieron 9 aislados de Cladophiarophora carrionii de pacientes con cromomicosis procedentes del Municipio Urdaneta, área endémica del estado Lara, Venezuela. Se trabajó con filtrado de conidias, a partir de un micelio en fase de conidiogénesis, obteniéndose una suspensión de conidas, estandarizadas a 5,5 x 105-1,2 x 106 UFC/ml, cuantificadas en cámara Neubauer. El inóculo fue constatado, realizando siembras en agar glucosado de Sabouraud en cultivo de placas. Con este método se observó un estrecho margen de variabilidad en los aislados estudiados. Es de fácil ejecución mostrando ser útil en las pruebas de sensibilidad in vitro a antifúngicos en hongos demateáceos

ABSTRACT

Background: The perception of the population about their needs must be considered in health care planning. Aim: To describe health care needs from the perspective of potential clients of public health services. Material and methods: An enquiry to a representative sample of 202 dwellings, ascribed to a Family Health Service, was done. Subjects were asked about the health problems in their family and neighborhood. Twelve families from this sample were randomly chosen and interviewed about their health conception, needs and demands. Results: The mean age of subjects, per dwelling, was 31 years. Fifty percent were nuclear families and 6 percent were mono parental. Perceived problems were economical in 60 percent and health related in 12 percent. Eighty percent of health problems were related to addictions and violence. Interviewed subjects associated health with lack of services, with their experience with illness and pain and with a risk of social isolation and incommunication. Health care demands were referred to a better medical care. People declared needs in environmental hygiene, physical and mental health self care, food and jobs. Conclusions: Using this information, simple strategies could be implemented to cope with health care demands of the population

ABSTRACT

A retropective study was perfomed to asses risk factors in patients with esophageal echalasia undergoing pneumatic dilatation. Of 140 patients who underwent 159 dilatations, 7 sustained esophageal perforation (4.4 percent). They were matched with a group of 52 non perforated, dilated achalasia patients. History of prior pneumatic dilatation and small esophageal diameter were found to be risk factors by chi square and ANOVA. Conclusions: 1) Pneumatic dilatation for esophageal achalasia is a procedure with 4.4 percent risk of perforation and 0.6 percent mortality rate. 2) The risk of developping an esophageal perforation is increased by previous pneumatic dilatation and small esophageal diameter. Another risk factor such as a possible anatomical weakness of the esophageal wall (and the likelihood of it being evaluated by ultrasonography) at the site of perforation is suggested.

ABSTRACT

Chilean universities employ a common admission scoring system for students, based on high school grades, mathematic and verbal academic aptitude tests, and specific biology and social sciences tests. Aiming to know the predictive values of these tests, the standarized scores obtained in the selection tests and academic performance of 1094 first year medical students, admitted in 1989 and 1990 to six universities, were analyzed. These students obtained high admission scores and their academic performance during the first year was low (mean grades ranged from 4.6 ñ 0.6 to 5.28 ñ 0.5 in different universities for a scale from 1 to 7). In all, except one university there was a correlation between admission scores and academic performance. Multiple regression analysis showed that admission scores explained a 13 percent of performance and that the parameters with better predictive value were high school grades, biology test and mathematics academic aptitude test, Verbal academic aptitude test did not have a predictive value

ABSTRACT

Accidental hypothermia, a condition seldomly seen in Chile, is defined as a spontaneous core temperature reduction to less than 35§ C and is associated with great morbidity and mortality. We report a 16 years old female intoxicated with liquefied petroleum gas that was admitted in coma, hypothermic, with severe hemodynamic derangement, lactic acidosis, rhabdomyolysis and iliofemoral phlebothrombosis. Peritoneal dialysis with solutions at 27§ C was used as a quick and safe means to revert hypothermia and avoid its complications
