ABSTRACT

The aim of this study is to examine the dorsal lingual epithelium of the peregrine falcon (Falco peregrinus) of the family Falconidae. The tongue in its dorsal, lateral and ventral surfaces is covered with a non-keratinized multilayered stratified squamous epithelium. Lamina propria is present beneath the epithelial layers. Morphometrically, thickness of the apex tongue epithelium is more than that in the tongue body. Thickness of the ventral surface of the tongue is less than that in the dorsal one. Thickness of the lateral surface of the tongue was thicker than that in the ventral one and tongue body. Large and small conical papillae appeared on the posterior dorsal surface of the lingual body. There are lingual glands in certain areas of tongue body with numerous openings through the dorsal surface.

ABSTRACT

La cría de búfalos de agua (Bubalus bubalis) se ha convertido en una ganadería cada vez más importante y común en nuestro país; sin embargo, afecciones como las gastroenteritis parasitarias representan una de las limitantes en el desarrollo de esta especie, provocando un impacto negativo sobre la producción cárnica y lechera. Los principales agentes etiológicos responsables de esta afección son los estróngilos digestivos (Nematoda: Strongylida) y coccidias del género Eimeria (Sporozoa: Eucoccidida). Con el objetivo de determinar el comportamiento de estas infecciones, se evaluaron mediante exámenes coprológicos mensuales a través de la técnica cuantitativa de McMaster, búfalos de cuatro grupos etarios (bumautes entre 8 y 18 meses de edad, bumautes mayores de 18 meses, sementales y búfalas), de ambos sexos, pertenecientes a un rebaño comercial del estado Falcón. Los estróngilos digestivos y las coccidias fueron los más prevalentes, con 25,2 y 46,2%, respectivamente. La abundancia del rebaño fue de 38±41,1 huevos por gramo (HPG) de heces para estróngilos y de 142,4±117,2 ooquistes por gramo (OPG) de heces para coccidias. Hubo diferencias estadísticas (p<0,05) al comparar los valores de prevalencia y abundancia de las infecciones por estróngilos digestivos y coccidias entre los grupos etarios y el sexo. Los valores de prevalencia y abundancia disminuyeron con la edad de los animales evaluados (estróngilos: prevalencias de 39,5; 34,0; 42,3; 15,8% y abundancias de 79,8; 47,2; 30,8; 12,2 HPG; coccidias: prevalencias de 71,3; 54,8; 38,5; 34,0% y abundancias de 379,1; 121,0; 44,2; 47,6 OPG), siendo superiores en machos que en hembras (estróngilos: prevalencias de 36,2 y 22,4%, y abundancias de 70,5 y 30,9 HPG; coccidias: prevalencias de 57,3 y 43,6% y abundancias de 166,3 y 131,5 OPG, respectivamente). Las mayores cargas parasitarias y las infecciones de importancia clínica se observaron en los bumautes entre 8 y 18 meses de edad (contajes mayores a 500 HPG y 5050 OPG). Las condiciones climáticas se encontraron en rangos favorables (25,6-29,3ºC, 77,0-89,0% de humedad relativa y 1,0-151,3 mm de precipitación) para el desarrollo de las formas preparasíticas de estróngilos digestivos y coccidias.


The breeding of water buffaloes (Bubalus bubalis) has become an increasingly important and common livestock in Venezuela; however, conditions such as gastrointestinal parasitism are one of the major constraints in the development of this species, with a negative impact on meat and milk production. The main etiologic agents responsible for this condition are digestive strongyles (Nematoda: Strongylida) and coccidia of the genus Eimeria (Sporozoa: Eucoccidida). This investigation evaluated the behavior of these infections in buffaloes of different age and sex. Samples were collected and examined monthly by the quantitative McMaster technique. The buffaloes were subdivided into four age groups (animals between 8 and 18 months of age, over 18 months, males and female buffaloes), the animals came from a commercial flock of the State of Falcon, Venezuela. The results show that the most prevalent parasites were strongyles and coccidian, 25.2% and 46.2%, respectively. The flock abundance was 38±41.1 eggs per gram (EPG) for strongyles and 142.4±117.2 oocysts per gram (OPG) forcoccidia. There were statistical differences (p <0.05) between age groups and sex of the buffalo, when comparing the values of prevalence and abundance of infections for gastrointestinal strongyles and coccidia. The prevalence and abundance values decreased, with increasing age of the animals tested (strongyles: prevalence of 39.5; 34.0; 42.3; 15.8% and abundance of 79.8; 47.2; 30.8; 12.2 EPG; coccidian: prevalence of 71.3; 54.8; 38.5; 34.0% and abundance of 379.1; 121.0; 44.2; 47.6 OPG), being higher in males than in females (strongyles: prevalence of 36.2 and 22.4%, and abundance of 70.5 and 30.9 EPG; coccidian: prevalence of 57.3 and 43.6% and abundance of 166.3 and 131.5 OPG). The highest parasitic loads and the clinically important infections were seen in 8 to 18 months old buffaloes (counts higher than 500 EPG and 5,050 OPG). Environmental conditions fell within favorable ranges (25.6-29.3ºC of temperature, 77.0-89.0% of relative humidity and 1.0-151.3 mm of precipitation) for the development of infective parasite forms of both digestive strongyles and coccidian.

ABSTRACT

Se estudia la evaluación y tendencia de la mortalidad perinatal, registrada en el Departamento de Obstetricia y Ginecología, Hospital "Dr. Adolfo Prince Lara", Departamento Clínico Integral de la Costa, Universidad de Carabobo, Puerto cabello-Estado Carabobo. Ocurrieron 130.977 nacimientos y 5.608 muertes perinatales, durante el lapso de 40 años (1969-2008). El número de muertes perinatales por lapso y su diferencia periódica, muestra una tendencia al aumento en los primeros 30 años (1969-1998), con una tasa de mortalidad perinatal elevada (entre 41 y 51 por mil nacidos) con tendencia al incremento. El lapso final de diez años (1999-2008), muestra un descenso en todas las cifras analizadas, la reducción de tasas fue de 5,74 por mil nacidos, con expresión porcentual de 13,76, y una tasa global promedio (1969-2008) de 41,36 por mil nacidos. Estos resultados nos señalan la realidad que en materia de salud hemos vivido, por lo tanto debemos analizar el servicio prestado con mucha responsabilidad. Se debera fortalecer actividades preventivas sanitarias de salud pública, elevar el estándar de vida de los pacientes, eventos que son responsabilidad del estado, a todo ello estamos dispuestos a acompañarlo


The evolution and trends of perinatal mortality were study in the Departamento de Obstetricia y Ginecología, Hospital "Dr. Adolfo Prince Lara", Departamento Clínico Integral de la Costa, Universidad de Carabobo. Puerto Cabello-Estado Carabobo. There were 130.977 births and 5.608 perinatal deaths registered during the period of 40 years (1969-2008). The number of perinatal deaths and the diference between regular periods, shows an increasing trend in the first 30 years (1969-1998), with a high perinatal mortality rate (between 41 and 51 per thousand births), with a tendency to increase. The final span of ten years (1999-2008), shows a decline in all figures analyzed, the reduction rate was 5.74 per thousand live births, with expression of 13.76 percent and the overall average (1969-2008) was 41.36 per thousand births. These results point to the fact that in health we have lived, so we must analyzed the service very seriously. There are health preventive public health standard of life of patients, and other events that are the responsibility of state, activities that we are willing to support

ABSTRACT

En Falcón, no se han realizado estudios relacionados con la toxoplasmosis. La finalidad de este estudio es determinar la prevalencia de anticuerpos anti-Toxoplasma gondii tipo IgM e IgG, en mujeres no embarazadas que acudieron al hospital “Dr, Rafael Gallardo”. El diagnóstico se hizo a través de inmunoensayo enzimático. El 85,5% resultaron negativas para la presencia de ambos anticuerpos, 14,3% mostraron valores positivos de IgG y 0,37% tuvo valores positivos para IgM. Se descartó la presencia de infección activa en los pacientes que resultaron IgG(+). La paciente IgM(+) se manejó como primoinfección. La baja prevalencia encontrada puede deberse a escasa exposición a factores de riesgo o al subregistro. Hacer el diagnóstico precoz permite iniciar medidas profilácticas que reduzcan la transmisión. El estudio serológico debe ser extendido a mujeres embarazadas y complementado con los datos epidemiológicos.


Studies related with toxoplasmosis have not been done at Falcon State, Venezuela. The aim of this study was to determine the IgM and IgG type anti-Toxoplasma gondii antibody prevalence in non pregnant women who attended the “Dr. Rafael Gallardo” Hospital. Diagnosis was made through an immune-enzymatic assay. Of the sera tested, 85.5% were negative for both antibodies; 14.27% of the sera were positive for IgG  and 0.37% for IgM. The presence of active infection was rejected in the IgG(+) patients. The one patient who was IgM positive was considered as recently infected. The low prevalence found may be due to scarce exposure to risk factors, or to a sub registration. An early diagnosis will allow initiating prophylactic measures that reduce transmission. Serologic studies should be extended to pregnant women and complemented with epidemiological data.

ABSTRACT

A partir de un pequeño y precario hospital construido en Coro a fines del siglo XVI hasta el moderno Hospital Universitario Alfredo Van Grieken, la medicina y la cardiología falconianas han recorrido un largo periplo. Con menguado recursos en sus comienzos, los médicos del Estado Falcón han sabido sobreponerse a todas las vicisitudes y dificultades para llevar adelante la tarea de ayuda de sus pacientes. Su perseverante afan por el progreso queda demostrado al ocupar el 2° lugar (antes que Caracas) entre los primeros en emplear los Rayos X confines diágnósticos. Sus mejores esfuerzos fueron dedicados a la construcción de hospitales públicos y no privados, lo cual nos habla de un encomiable espíritu en procura del bien colectivo. Este trabajo va dirigido a los jóvenes profesionales médicos de hoy, para que, inspirados en el interés social de que hicieron gala sus predecedores, se encaminen por la honrosa senda de un ejercicio genuinamente humanitario.


Medicine and cardiology in Falcon have made a long journey, from their beginning at a small, modest hospital built in Coro at the end of the 16 th century to themodern Alfredo Van Grieken University Hospital. With only limited resource in their early days, the doctors of the State of Falcón have managed to overcome all kinds of vicissitudes and dificulties in order to perform the tesk of helpíng their patients. Proof of their persistent desire for progress is the fact that Falcón was among the first states to employ x-reys for diagnostic purposes, coming second (ahead of Caracas). Their most admirable efforts were in the construction of public and non-private hospitals, which speaks of praiseworthy public spiritedness. This paper is aimed at today´s young medical professionals so that, inspired by the lack of interest in monetary gain displayed by their predecessors, they travel the honorable path of practicing their profession in a genuinely humanitarian manner.

ABSTRACT

En Punta El Chaure por una extensión de 263 m se ubica un estrato de espesor variable entre 0,23 y 1,35 m. de dunas fósiles presumiblemente pleistocenas; hacia el NE, el depósito permanece recubierto alternativamente por sedimentos eólicos actuales y hacia el SW entran en contacto con los acantilados inactivos de El Chaure. La existencia de este modelado plantea consideraciones paleogeográficas de interés para la evolución de la costa norte de Paraguaná. Los objetivos del trabajo son: a) Establecer las características sedimentológicas de las formas topográficas estudiadas b) Identificar los procesos bajo los cuales evolucionan actualmente. c) Caracterizar las formas geomorfológicas actuales. La metodología utilizada se basa en trabajo de campo, análisis petrográfico de secciones finas, tamizado en seco, curvas granulométricas, parámetros estadísticos, análisis morfoscópico y calcimetría. Se concluye que las eolianitas en campo, se presentan como areniscas de grano medio a fino, bien cementadas de color crema con estratificación cruzada, observándose en las secciones finas abundante cuarzo detrítico. La redondez varía desde subangular en las tallas medias a subredondeada en las más gruesas. La selección es moderada a pobre, la asimetría negativa y la curtosis leptocúrtica. Estos resultados difieren de los depósitos actuales. El contenido de carbonato de calcio es superior al 50 por ciento en ambos casos. Las dunas fósiles presentan rasgos de morfología cárstica que favorecen el desmantelamiento.


A probable Pleistocene fossil dunes layer is located at Punta El Chaure, its thickness varies from 0,23 to 1,35 m and its extension goes about 263 m towards NE, the layer is covered by aeolian sediments and it makes contact with inactive cliff to SW. The presence of these deposits raises important paleogeographic considerations for Paraguaná north coast evolution studies. The objectives of this research are: a) to establish sedimentary characteristics of these topographic forms, b) to identify present evolution processes, and c) to characterize actual geomorphologic forms. The methodology used was based on field work, petrography analysis of thin sections, dry sieving, statistic parameters, granulemetric curves, morphologic analysis, and calcium content. Conclusions: Cream eolianites are found in field with cross stratification and good cementation of sandstone. Main grain size ranges from medium to fine. Abundant detritic quartz is observed under microscope. Roundness varies from sub-angular in medium sizes to sub–rounded in thick ones. Statistic parameters show a selection from moderate to poor, negative asymmetry and leptokurtic kurtosis. These results differ from actual deposits. The content of Calcium Carbonate is higher than 50 percent in both cases. Fossil dunes show karsts morphology traits which facilitate dismantlement.
