Interferencias oclusales y su relación con las maloclusiones funcionales en ni?os con dentición mixta
Quintana Espinosa,María Teresa; Martínez Brito,Isabel;
Revista M??dica Electr?3nica , 2010,
Abstract: the occlusal interferences are a frequent problem in temporal and mixed dentition. they are associated to functional malocclusions with anterior crossed biting, posterior crossed biting, and also to facial anomalies and affections of the temporomandibular articulation. we carried out a descriptive, observational, transversal study, where we examined 820 primary school children of the contreras health area, municipality of matanzas, to identify the occlusal interferences related to the presence of functional anterior crossed biting, functional unilateral posterior crossed biting. 138 of the examined children presented occlusal interferences; 36.9 % of them presented anterior crossed biting, and 63.0 % posterior crossed biting. the precocious detection of occlusal interferences will give us the possibility of intercepting dental malocclusions and also of preventing dentomaxillofacial anomalies and alterations of the temporomandibular articulation.

Abstract: Objetivo: determinar si la presencia de valores persistentemente positivos de anticuerpos antifosfolipídicos (AAF) está relacionada con trombosis recurrente en el seguimiento de pacientes con síndrome antifosfolipídico (SAF). Métodos: se analizaron 141 pacientes con SAF (criterios de Sapporo). Los valores de anticoagulante lúpico (AL) y anticuerpos anticardiolipina (AAC) fueron definidos como persistentemente positivos cuando más del 75% de las determinaciones fueron positivas durante el seguimiento (los AAF fueron medidos en cinco o más ocasiones). La trombosis en el seguimiento fue definida como una trombosis recurrente en pacientes con episodios trombóticos previos o nuevos episodios en aquellos pacientes con pérdidas fetales previas. Resultados: ochenta y nueve pacientes presentaban SAF primario, 34 asociado a lupus eritema-toso sistémico (LES), 14 con síndrome similar al lupus, 3 con síndrome de Sjogren y 1 con enfermedad de BehObjective: to determine if the presence of persistently positive valúes of antiphospholipid (aPL) antibodies is related with recurrent thrombosis in the follow-up of patíent with antiphospholipid syndrome (APS). Patients and Methods: 141 patients with APS (Sapporo's criteria) were analyzed. Lupus antico-agulant (LAC) valúes and anticardiolipin antibodies (aCL) were defined as persistently positive when more than 75% of determinations were positive during the follow-up (aPL were measured on 5 or more occasions). Thrombosis in the follow-up was defined as a recurrent thrombosis in patient with previous thrombotic events or new events in those patients with previous fetal losses. Results: 89 patients suffered from primary APS, 34 associated to systemic lupus erythematosus (SLE), 14 to SLE-like, 3 to Sjogren's syndrome, and 1 to Behcet's disease. 56% liad a history of thrombosis, 29% of fetal losses, and 15% both thrombosis and fetal losses. Median time of follow-up and between the diagnosis and the last aPL determination was 68 months and 65 months (9-180), respectively. Median of determinations by patient was 8 (5-27). 31 patients suffered from thrombosis in the follow-up, 28 of them in form of recurrent thrombosis. 58 (41%) patients liad persistently positive aPL during follow-up, thus: 23 (39,65%) aCL IgG y LAC, 12 (20,7%) LAC, 8 (13,8%) aCL IgG, 5 (8,6%) aCL IgM, aCL IgG y LAC, 4 (6,9%) aCL IgM, 3 (5,1%) aCL IgG y aCL IgM y 3 (5,1%) aCL IgM y LAC, respectively. Risk for recurrent thrombosis during follow-up was increased in persistently positive aPL patients (OR 3,53; 95% CI 1,53-8,16; p=0,003) compared with transiently pos

Abstract: Las interferencias oclusales son un problema frecuente en la dentición temporal y mixta, están asociadas a maloclusiones funcionales como mordidas cruzadas anteriores, mordidas cruzadas posteriores, así como anomalías faciales y afectaciones de la articulación temporomandibular. Se realizó un estudio observacional descriptivo de corte transversal, donde fueron examinados 820 ni os pertenecientes a escuelas primarias, área de salud Contreras, del municipio de Matanzas, con la finalidad de identificar las interferencias oclusales que se relacionaron con la presencia de mordida cruzada anterior funcional, mordida cruzada posterior unilateral funcional. Del total de ni os examinados, 138 presentaron interferencias oclusales, de ellos el 36,9 % presentó mordida cruzada anterior, y un 63,0 % mordida cruzada posterior. La detección precoz de las interferencias oclusales nos dará la posibilidad de la intercepción de maloclusiones dentarias, así como en la prevención de anomalías dentomaxilofaciales y alteraciones de la articulación tempomandibular.

Abstract: Diversos tipos de adenocarcinomas se han descrito en diferentes especies, pero los adenocarcinomas tiroideos son raros en aves. Aquí se describen hallazgos patológicos de un adenocarcinoma tiroideo en faisán versicolor (Phaisanus versicolor), para considerarlo en el diagnóstico diferencial de enfermedades crónicas en aves silvestres del orden Galliforme. El hallazgo anatomopatológico se describe en un faisán macho, de seis a os de edad, que presentó difi cultad respiratoria sin secreción 24 horas antes de morir. A la necropsia se halló masa multinodular no encapsulada de consistencia suave, desde la bifurcación de la tráquea, que se extiende hacia la parte craneal de los pulmones, hasta la cara interna de los huesos costales del lado izquierdo. Las características histológicas y localización de la neoplasia establecieron el diagnóstico de adenocarcinoma tiroideo con patrón folicular. Este trabajo deja el precedente de una lesión que puede incluirse en el diagnóstico diferencial de enfermedades crónicas para la especie faisán versicolor.

Abstract: El objetivo principal de la atención hospitalaria al paciente con enfermedad terminal es brindar asistencia a estos pacientes en sus últimas semanas o días de vida, que por determinadas condiciones no pueden mantenerse en su domicilio. El paciente presentará las características que definen la "situación de últimos días". La siguiente revisión sienta las pautas a seguir con los enfermos terminales en las salas hospitalarias, así como la interdisciplinariedad que conlleva la atención a estos pacientes. The main objective of hospital care for terminal patients is to assist terminal patients that for different reasons can not remain in their homes to spend their last weeks or days of life. They will present the features that typically define the last days of life in this kind of patients. The following review states the guidelines to be followed when treating hospitalized terminal patients and the interdisciplinary approach that it requires.

Abstract: Los cuidados paliativos son una modalidad de la medicina en la que el ejercicio profesional se centra en la atención integral, activa y continuada del paciente y sus familiares, realizada por un equipo multidisciplinario cuando la expectativa no es la curación, sino proporcionar calidad de vida sin alargar la supervivencia. Deberá cubrir aspectos físicos, psicológicos, sociales y espirituales, si es necesario se extenderá al período de duelo. La siguiente revisión sienta las pautas a seguir con los enfermos terminales en la atención primaria de salud, así como la interdisciplinariedad que exige la atención a estos pacientes. Palliative care is a form of medicine in which professional practice focuses on general, active and continuous care both, to patient and their families, by a multidisciplinary team The expectation is not to heal the patient, but to provide a better life quality without prolonging survival. Palliative cares should cover physical, psychological, social and spiritual aspects and, if necessary, they will be extended to the mourning period. The following review provides the guidelines to be followed when dealing with terminal patients and the interdisciplinary approach that involves the care provided to these patients.

Abstract: We analyze here the keys of the original approach about the twofold cost: the return to the asexuality starting with a mutant female, with the same reproductive capacity than a sexual one, and with double genetic-reproductive success. We propose a new approach in which 1) all individuals in a population have regulatory mechanisms of reproductive mode, and when such change occurs, it happens in all its population at the same time; 2) after a change of reproductive mode in the population there can be variations in average offspring per female, according to the environmental quality; and 3) the genetic-reproductive success of the males and its unequal paternity success are accounted for. Results: The most advantageous reproductive strategy depends on the demographic situation of the population and the degree of the unequal paternity success of males. For harem values observed in nature and in populations with moderate growth rate, stable or decreasing population, the sexual strategy is advantageous. If the population growth rate is high, the asexual strategy is advantageous. In species subject to high demographic fluctuations the best strategy depends on the ability to predict the time of occurrence of the population bottleneck: if predictable, the best strategy is the alternation of generations, if not, permanent parthenogenesis.

Abstract: the leaves of the chamaedorea quezalteca palm are an important non-timber forest resource for the dwellers of the sierra madre de chiapas, méxico. the aim of this study was to evaluate the effect of artificial defoliation during one year (july 2008 to july 2009) on leaf production, mortality and reproduction of c. quezalteca at three sites of the el triunfo biosphere reserve, chiapas, méxico. six hundred individuals were selected in three size categories defined by the number of stems (1-3, 4-6 and >7). the experimental design was mixed factorial with two fixed factors (treatment and size) and one random (site), and forest cover as a covariate, with three treatments of defoliation (30, 60 and 100 %) and the control (0 %); an analysis of variance was performed with the data. the production of leaves was significant (p<0.05) in relation to plant size and intensity of defoliation, but such response depended on the combination of factor levels. leaf production increased with harvest intensity (defoliation) and size categories. during the experiment, eight individuals were recorded dead and 20 % of all the selected individuals lost one or more stems. no differences were found (p<0.05) between treatments and the control in the production of inflorescences and infructescences between the start of the experiment and after one year, nor in fruit production after a year. results indicate that leaf harvest in an annual period increased leaf production but did not change the reproduction and survival of individuals.
