RESUMO
RESUMEN El objetivo del estudio fue evaluar los parámetros genéticos de las características biométricas del fruto y semillas de Caesalpinia ebano. La investigación se realizó en Montería (Colombia), se seleccionaron diez árboles, y de cada uno diez frutos tomados al azar. Se realizaron análisis de varianza y estimación de parámetros genéticos para nueve características: peso fresco del fruto, largo del fruto, ancho del fruto, grosor del fruto, número de semillas/fruto, peso de semillas por fruto, peso de una semilla, volumen de una semilla y densidad de una semilla. Se detectaron diferencias estadísticas (p < 0,01) entre árboles, para todas las características, excepto para el ancho del fruto y peso de una semilla; denotando la existencia de variabilidad genética entre los árboles para peso del fruto, largo del fruto, grosor del fruto, número de semillas y densidad de una semilla. El peso y largo del fruto presentaron la heredabilidad media familiar y heredabilidad en el sentido estricto con los valores más altos (h2 Fam > 82 % y h2 E > 30 %). La ganancia genética esperada fue mayor del 10 % en cinco de las nueve características estudiadas, y mayor del 20 % para número de semillas y peso de las semillas (27,31 y 27,87 %, respectivamente). Los caracteres peso y largo del fruto se podrían transmitir a las generaciones sucesivas, con mayor posibilidad de éxito, mediante la selección fenotípica de árboles.
ABSTRACT The objective of the study was to evaluate the genetic parameters of the biometric characteristics of the fruit and seeds of C. ebano. The investigation was carried out in Montería, Córdoba (Colombia); ten trees were selected and from each, ten fruits taken at random. Variance analysis and estimation of genetic parameters for nine traits were carried out: fresh fruit weight, fruit length, fruit width, fruit thickness, number of seeds/fruit, weight of seeds by fruit, weight of one seed, volume of one seed and density of one seed. Statistical differences (p < 0.01) were detected between trees, for all traits except for width of the fruit and weight of a seed; denoting the existence of genetic variability between trees for fruit weight, fruit length, fruit thickness, number of seeds and density of a seed. The weight and length of the fruit presented the highest family heritability and narrow sense heritability (h2 Fam > 82 % and h2 E> 30 %). The expected genetic gain was greater than 10 % in five of the nine studied traits, and greater than 20 % for number of seeds and weight of seeds (27.31 and 27.87 %, respectively). The traits fruit weight and length could be transmitted to successive generations, with greater chance of success, by phenotypic selection of trees.
RESUMO
CASE: A 40-year-old Colombian woman presented with a 7-year history of progressive lower-limb pain. Sclerosis of the diaphyseal tibia and femur was observed in her latest x-ray images. A narrowing of the medullary canal is observed in Camurati-Engelmann disease (CED), a rare and progressive diaphyseal dysplasia that was confirmed in this patient by genetic testing. Medical treatment was unsuccessful; thus, surgical treatment consisted of decompression by drilling of the medullary canal was performed, achieving successful pain release. CONCLUSION: Surgical treatment should be considered for patients with CED when the medical treatment is unsuccessful because doing so reduces bone overgrowth, leading to pain relief.

El objetivo de este artículo es presentar un protocolo simplificado para la instalación inmediata de una prótesis definitiva sobre 4 implantes mandibulares. Fue realizado en una paciente de sexo femenino de 72 años, desdentada total. Se inició el tratamiento con la confección de una prótesis removible convencional hasta la prueba de articulación dentaria, a partir de lo cual se obtuvo una guía multifuncional. En la cirugía se instalaron 4 implantes Strong SW (SIN®, Sao Paulo, Brasil) entre agujeros mentonianos. Se atornillaron pilares Mini-Abutment y se tomó la impresión utilizando la guía. Al segundo día se probó la estructura metálica con el enfilado dentario en cera y al tercer día se realizó la instalación de la prótesis terminada con torque manual. A los 10 días se retiró la sutura y se dio torque a los tornillos protésicos (10 N/cm). La paciente ha asistido a controles, sin presentar complicaciones hasta este momento.
The aim of this paper is to present a simplified protocol for immediate installation of a definitive prosthesis over four jaw implants. This was performed on a totally edentulous female patient of 72 years. The treatment was initiated with the preparation of a conventional removable prosthesis until the dental articulation test from which a multifunctional guide was obtained. At surgery, four Strong SW (SIN®, Sao Paulo, Brazil) implants were installed between mental foramen. Mini-Abutments were screwed and the impression was made using the guide. On the second day the metal structure was tested with the dental articulation in wax and on the third day the definitive prosthesis was installed with manual torque. The suture was removed 10 days after surgery, and the torque was given to prosthetic screws (10 N/cm). The patient was followed up every 6 months, with no complications so far.
