Detección de displasias corticales asistida mediante métodos semiautomáticos de espesor cortical

 Objetivo: Evaluar la detección de displasias corticales utilizando un método semiautomá- tico de cuantificación morfométrica basado en superficie mediante la localización de zonas con espesor cortical anormal. Materiales y métodos: Se seleccionó un grupo de pacientes remitidos por diagnóstico de epilepsia refractaria para la detección de lesiones cerebrales. El espesor cortical se midió utilizando algoritmos automáticos de morfometría basado en superficie de imágenes de resonancia magnética en cada uno de los pacientes, los cuales fueron comparados con un grupo control de sujetos sanos pareados por edad. Resultados: Se realizó la cuantificación de espesor cortical en 4 de los 5 pacientes selec- cionados. Se encontraron áreas de engrosamiento cortical en las zonas de displasia cortical conocidas que se relacionaron con las zonas detectadas previamente por el radiólogo en la secuencia FLAIR de cada paciente. Se hallaron diferencias en los mapas de espesor cortical de cada paciente respecto al grupo control. Conclusión: La cuantificación morfométrica de espesor cortical es una técnica que promete ser de utilidad como asistencia computarizada al diagnóstico de las displasias corticales

Contribution of common and rare variants to bipolar disorder susceptibility in extended pedigrees from population isolates.

Current evidence from case/control studies indicates that genetic risk for psychiatric disorders derives primarily from numerous common variants, each with a small phenotypic impact. The literature describing apparent segregation of bipolar disorder (BP) in numerous multigenerational pedigrees suggests that, in such families, large-effect inherited variants might play a greater role. To identify roles of rare and common variants on BP, we conducted genetic analyses in 26 Colombia and Costa Rica pedigrees ascertained for bipolar disorder 1 (BP1), the most severe and heritable form of BP. In these pedigrees, we performed microarray SNP genotyping of 838 individuals and high-coverage whole-genome sequencing of 449 individuals. We compared polygenic risk scores (PRS), estimated using the latest BP1 genome-wide association study (GWAS) summary statistics, between BP1 individuals and related controls. We also evaluated whether BP1 individuals had a higher burden of rare deleterious single-nucleotide variants (SNVs) and rare copy number variants (CNVs) in a set of genes related to BP1. We found that compared with unaffected relatives, BP1 individuals had higher PRS estimated from BP1 GWAS statistics (P = 0.001 ~ 0.007) and displayed modest increase in burdens of rare deleterious SNVs (P = 0.047) and rare CNVs (P = 0.002 ~ 0.033) in genes related to BP1. We did not observe rare variants segregating in the pedigrees. These results suggest that small-to-moderate effect rare and common variants are more likely to contribute to BP1 risk in these extended pedigrees than a few large-effect rare variants

Comprensiones de perdón, reconciliación y justicia en víctimas de desplazamiento forzado en Colombia

El presente estudio buscó comprender las concepciones de perdón, reconciliación y justicia, en el marco del conflicto armado, de 68 personas víctimas de desplazamiento forzado residentes en el municipio de Soacha (Cundinamarca, Colombia). Se realizó a través de la metodología cualitativa empleando el método de teoría fundamentada. Se encontró que el perdón se entiende como un tránsito de emociones negativas a positivas; además, es sinónimo de olvido. La reconciliación se entiende como un proceso de restablecimiento de vínculos. La justicia (restaurativa y/o distributiva) se evidencia como necesaria para que se dé un proceso de perdón y reconciliación en el marco del conflicto armado. Además, surge de manera emergente la relevancia que tiene la religión en los procesos de perdón y reconciliación.The present study analyzes the concepts of forgiveness, reconciliation and justice, in the context of the Colombian armed conflict, on the part of 68 victims of forced displacement who live in the town of Soacha (Cundinamarca, Colombia). It is based on a qualitative methodology drawn from grounded theory. It found that those victims understood forgiveness to involve a transition from negative to positive emotions, and as a synonym for forgetfulness, while reconciliation was understood as a means to restore broken links. Thus, in the context of an armed conflict, justice (restorative and / or distributive) is a requirement for securing forgiveness and reconciliation. The study also reveals the importance of religious faith in the acceptance of forgiveness and reconciliation by the victims.Este estudo pretendeu compreender as concepções de perdão, reconciliação e justiça, no âmbito do conflito armado, de 68 pessoas vítimas de deslocamento forçado residentes no município de Soacha (Cundinamarca, Colômbia). Realizou-se por meio da metodologia qualitativa e empregou-se o método da teoria fundamentada. Constatou-se que o perdão se entende como uma transição de emoções negativas a positivas; além disso, é sinônimo de esquecimento. A reconciliação entende-se como um processo de restabelecimento de vínculos. A justiça (restaurativa e/ou distributiva) evidencia-se como necessária para que o processo de perdão e reconciliação aconteça no contexto do conflito armado. Ainda, surge de maneira emergente a relevância que a religião tem nos processos de perdão e reconciliação

Retrospective study of dental anomalies and bone alterations of the maxilla and mandible in children 5 to 14 years of age from the clinics of the college of dentistry, University of Antioquia

ABSTRACT: The purpose of this study was to carry out an epidemiological retrospective study on the type and frequency of radiographic dental and bone alterations in patients from 5 to 14 years of age who consulted the Dental Clinic (Child and the Adolescent Clinics) of the College of Dentistry at the University of Antioquia between the years 2000 and 2002. Methods: 428 panoramic radiographs with adequate density, contrast and definition were analyzed using also the dental records as support. The films were read by a dental radiologist who defined the type of bone alterations and dental anomalies present. A descriptive statistical analysis was performed Results: the sample consisted of 232 males (54.20%) and 196 females (45.79%). In the Maxilla and Mandible: 33 x-rays were found with pathological radiolucent images (7.68%): 21 females (4.89%) and 12 males (2.79%); just one patient (0.23%) with pathological radio opaque images. In the teeth: 272 x-rays (63.40%) with presence of dental anomalies: 149 males (34.73%) and 123 females (28.67%), involving 1120 teeth. The anomalies found were: dens in dente, tooth agenesis, Taurodontism, macrodontia, conic shaped teeth, supernumerary teeth, microdontia, transpositions, fusions, mesiodens, retained teeth, gemination, enamel spur, and enamel pearls in this order of frequency. Conclusions: this study showed that the population affected with some radiographic abnormalities was 71.32%.RESUMEN: El propósito de esta investigación es efectuar un estudio retrospectivo epidemiológico sobre el tipo y frecuencia de alteraciones a nivel óseo y dental, en pacientes de cinco a catorce años que consultaron la Clínica del Niño y el Adolescente de la Facultad de Odontología de la Universidad de Antioquia entre los años 2000 y 2002. Métodos: se analizaron 428 radiografías panorámicas análogas con adecuada nitidez, densidad, contraste y definición, usando las historias clínicas como soporte. Las placas fueron leídas por un radiólogo dental definiendo el tipo de alteraciones óseas y anomalías dentales presentes. Se efectúo un análisis estadístico de tipo descriptivo. Resultados: la muestra fue de 232 hombres (54,20%) y 196 mujeres (45,79%). En maxilares se encontraron 33 radiografías de pacientes con imágenes radiolúcidas patológicas (7,68%): 21 de sexo femenino (4,89%) y 12 de sexo masculino (2,79%), y solo un caso (0.23%) con imágenes radiopacas patológicas. En los dientes se presentaron 272 radiografías (63,40%) con presencia de anomalías dentales: 149 pertenecían a hombres (34,73%) y 123 a mujeres (28,67%), que incluyeron 1.120 dientes. Las anomalías encontradas fueron: dens in dente, agenesias, taurodontismo, macrodoncias, dientes en forma cónica, supernumerarios, microdoncias, transposiciones, fusiones, mesiodens, dientes retenidos, geminaciones, espolones de esmalte y perlas de esmalte, en ese orden de frecuencia. Conclusiones: la población afectada por alguna alteración fue del 71,32%
