Basal Extended Mentoplasty.

Introduction: The chin is one of the most visible facial structures. Chin surgery, was initially described, for, the treatment of facial abnormalities, advancing the mandibular symphysis; achieved anterior displacement of the base of the tongue showing some value in the treatment of snoring and obstructive sleep apnea, and achieved adequate lip competence. We designed the Basal Extended Mentoplasty (BEM) based on the needs of patients orthodontically compensated, but dissatisfied with the appearance of his face as well as upper airway problems looking for a solution to this, design and planning the advances of the chin. Materials and Methods: Patients operated in the service of Maxillofacial Surgery, Specialist Hospital, "Dr. Bernardo Sepulveda "XXI Century National Medical Center, during the period of 2015-2019, orthodontically compensated patients, with labial incompetence and Class II skeletal. Sixty-five patients were operated during this period, and eight cases are presented. Results: Lip competition, osseointegration of the segments is observed, with a proper projection of the lower third, no nerve or vascular damage in the area. Conclusions: The design of the osteotomy is for orthodontically compensated patients with labial incompetence and Class II skeletal, giving a result mandibular lengthening. The BEM achieved adequate lip competence demonstrated by an interlabial gap of 0 mm, achieved adequate osseous consolidation of the fracture site with a more harmonious facial balance and profile, without nerve or vascular damage with spectacular results.

Ideación suicida y su relación con la inteligencia emocional en universitarios colombianos / Suicidal ideation and its relationship to emotional intelligence in Colombian college students

Introducción: El suicidio es un problema de salud mundial que se encuentra en aumento, especialmente entre la población joven. Pensamientos sobre la muerte e ideas de quitarse la vida pueden presentarse de manera frecuente en estudiantes universitarios a lo largo del semestre académico por las nuevas experiencias de vida a los jóvenes, quienes se ven confrontados con importantes presiones sociales, personales, económicas y académicas. Algunos universitarios logran hacer frente a éstas demandas de manera efectiva mientras otros no.

Se analizó la presencia de ideas suicidas en una muestra de 186 estudiantes universitarios, entre los 18 y 37 años de edad. Como instrumentos de medición se aplicaron los inventarios de ideación suicida de Beck y el Trait Meta Mood Scale-24. Se analizaron los datos en comparación a hallazgos previos en el tema del suicidio en en país. Resultados: El mantenimiento de ideas suicidas entre universitarios colombianos responde a dificultades de éstos jóvenes para comprender sus estados emocionales, reparar emociones negativas y afrontar problemas. Conclusión: las habilidades de inteligencia emocional son factores psicológicos que juegan un rol fundamental en la aparición y mantenimiento de ideas suicidas en los jóvenes universitarios colombianos.

Introduction: Suicide is a world health problem that is increasing around the world, especially amongst young of committing people. Thoughts about death and ideas of commiting suicide can occur frequently in college students during an academic semester by new life experiences to young people, who are confronted with important social, personal, economic and academic pressures. Some college students succeed by managing these demands effectively while others do not. The emotional competences that allow an individual to successfully cope with adverse situations are known as "emotional intelligence". The present research work seeks to gain some understanding about the way in which suicidal ideation is related to flaws in the emotional intelligence abilities for coping with adversity. Objectives: To identify the relationship between suicide ideation and emotional intelligence in Colombian college students Methodology: Correlational descriptive study, cross-sectional design. The presence of suicidal ideation was assessed for a sample of 186 college students between 18 and 37 years of age. The Beck Suicidal Ideation Inventory and the Trait Meta Mood Scale -24 were used as measurement instruments. Data analysis is presented in relation to previous findings of suicide studies in Colombia. Results: College students with difficulties for understanding their emotional states, for repairing their negative emotions and for coping with stressors are more likely to develop suicidal thoughts during the academic semester. Conclusions: Emotional intelligence skills are psychological factors that play a fundamental role in the development and maintenance of suicidal thoughts in young Colombian college students.

Detection of antibodies against Chlamydophila abortus in Costa Rican sheep flocks.

A total of 359 sheep samples from 15 flocks were analyzed for the presence of antibodies against Chlamydophila abortus using a commercial Enzyme linked Immunosorbent Assay (ELISA). Antibodies were detected in 19 (5.29%) sheep from 12 (80%) flocks. Seropositive animals were found in all analyzed regions (Central, Chorotega, Atlantic Huetar, North Huetar and Central Pacific) determining prevalence between 0.28% and 4.4%, and intra-flock positivity between 3.7% and 25.0%. The survey revealed two risk factors associated with seropositivity; introducing animals (males and females), embryos, or semen from other farms or from abroad without any sanitary certification, and flocks not having quarantine areas or separated boxes for diseased animals. No clinical signs of disease were observed in positive seroreactors. C. abortus seems to be present in Costa Rica in a very low prevalence in sheep flocks. Further studies, to isolate the bacteria are required. Finally, implementation of control measures to prevent the spread of C. abortus is recommended.

Relación entre burnout y engagement académicos con variables sociodemográficas y académicas / Relationship between burnout and academic engagement with sociodemographic variables and academic

Este estudio buscó esclarecer la interdependencia entre burnout académico (BA) y engagement académico (EA) en estudiantes universitarios del área de la salud, y profundizar en la caracterización de esta relación a partir de sus asociaciones con variables sociodemográficas y académicas (desempeño académico, DA). Se utilizó un diseño observacional y correlacional de tipo multivariado con una muestra, constituida aleatoria y estratificadamente por 802 estudiantes de los programas de medicina, enfermería, fisioterapia y psicología de universidades privadas de Barranquilla, Colombia. Los instrumentos utilizados fueron el MBI-SS, el UWES-S y un cuestionario sobre condiciones socioeconómicas y académicas. El análisis de las relaciones halladas entre BA y EA permitió considerarlos articulados como extremos de un mismo continuo fenoménico o factor, compuesto por las dimensiones de vigor, dedicación, ineficacia académica y cinismo, con valores opuestos en los extremos o polos del factor. Se identificaron variables sociodemográficas y académicas asociadas con los polos del BA y del EA del factor reconocido, donde el BA resultó un buen predictor de mal DA, y el EA un buen predictor de buen DA.

This study aims to clarify the interdependence between Academic Burnout (ab) and Academic Engagement (ae) in undergraduate students, and to describe this relationship based on their associations with demographic and academic variables (Academic Achievement - aa). A multivariate, correlational observational design was used, with a stratified random sample of 802 students from the programs of medicine, nursing, physiotherapy and psychology of private universities of Barranquilla, Colombia. The instruments used were the mbi-ss, the uwess and a questionnaire about academic and socioeconomic variables. The analysis of the relationship between ab and ae, suggests considering each of these syndromes as extremes of the same phenomenic continuum or factor, composed by the dimensions of Vigor, Dedication, Academic Inefficacy and Cynicism , with opposite values at the extremes or poles of the factor. Demographic and academic variables were associated with the poles of the ab and the ae of the acknowledged factor, where the ab was a good predictor of poor aa, and the ae a good predictor of good aa.

[Castleman's disease. Review of five cases]. / Enfermedad de Castleman. Presentación de cinco casos.

It has been reported five cases of Castleman s disease. They were admitted at Hermanos Ameijeiras Surgical-Clinic Hospital. In four out of the five cases belonged to hyaline-vascular histological variety and one case to plasmacellular variety. All the cases which belonged hyaline-vascular variety were located and one of them was complicated with sarcoma of dendritic follicular cells. The plasmacellular variety was of the multicentric type. Of the four located cases two of them were retroperitoneals and they received surgical treatment only; the case of cervical location was treated with radiotherapy and steroids and the forth one of axillary location was treated with surgical removal followed of radiotherapy. The last one case, of plasma-cell and multicentric type, was only treated with prednisone. All the patients are still alive and only the one with plasmacellular variety has symptoms yet.

Variaciones anatómicas del círculo arterial de la base cerebral / Anatomicals variations of the arteries cincle of the braim basis

El objetivo principal de este Trabajo el estudio de las variaciones en frecuencia, distribución y diámetro de las arterias del polígono de la base cerebral en cadáveres obtenidos en la región centroccidental de Venezuela. Se utilizó la técnica del lavado de piezas, disección e inyección de arterias con gelatina y fijación de piezas con el método de Laskosky, haciendo recoleción de datos con tabulación y análisis. Se comprobó que en nuestro medio, como se ha demostrado en otros sitios, la composición del polígono de la base cerebral es muy variable. Que el mayor índice de ausencia y de multiplicidad (en nuestro caso duplicidad) lo posee la comunicante anterior (asiendo frecuente de aneurismas cerebrales) y que la escasa variación del origen de las cerebrales posteriores y comunicantes posteriores debe tenerse presente e investigarse en casos de afecciones cerebrovasculares que comprometan los vasos del círculo arterial de la base cerebral
