El criterio de calidad de las revistas que se debe respetar es el grado de endogamia editorial, además del grado de endogamia autoral1. Definimos endogamia editorial como la pertenencia a una institución u organización que se encuentra estrechamente relacionada con una editorial2 y además que pueda generar conflictos de interés, en cuanto a la endogamia autoral nos referimos a los autores que contribuyen con manuscritos que pertenecen al comité editorial o están estrechamente relacionados con el mismo; últimamente la ciencia abierta y las políticas de transparencia en los procesos editoriales pone en descubierto el grado de endogamia de las revistas científicas que no escapan a la observación de los autores para decidir publicar en una revista en específico3. Muchas organizaciones ponen sus reglas según los organismos a los cuales representan ya sean universidades, hospitales o institutos de investigación; la Revista Científica Ciencia Médica de manera general tiene la misión de evitar ambos tipos de endogamia. La editorial se basa en diversas guías como la del Committe on publication ethics (COPE)4 y la International committe of medical journal editors (ICMJE) haciendo hincapié en el código ético referente a endogamia; los editores evalúan los manuscritos enviados para su posible publicación solo sobre la base del mérito científico del contenido de los mismos. Para cumplir este objetivo los editores y los revisores o miembros del comité editorial como autores no deben estar envueltos en el proceso editorial y quedan excluidos de las decisiones acerca de manuscritos en los que sean autores corresponsales o que contribuyan como autores. La Revista Científica Ciencia Médica establece este mecanismo que está claramente definido en nuestras políticas editoriales acerca del envió de manuscritos, estas decisiones priorizan la calidad científica de los manuscritos enviados la revista en cuanto a la endogamia autoral. La política editorial de la Revista Científica Ciencia Médica trata de combatir contra la endogamia autoral mediante la publicación de nuestros artículos en revistas externas. Al ser una revista conformada por un comité de estudiantes de medicina y otras áreas de la salud contamos con una red de docentes formados en diversas áreas para la revisión de manuscritos, además contamos con una red de médicos tanto del interior del país como del exterior que cumplen la función de revisores externos, quienes realizan la revisión por pares a doble ciego, se realiza también la invitación de revisores externos a nuestra institución con trayectoria científica alejándonos cada vez más de la endogamia editorial; la idea principal acerca de evitar la endogamia es brindar calidad a las revisiones realizadas para su publicación, el porcentaje de endogamia que se permite en las diversas revistas científicas en promedio no supera el 25%5 y esta es la meta, conseguir un porcentaje de endogamia autoral menor al 25%, restringiendo la publicación solamente de los mejores artículos que se presentan de parte del comité editorial, de manera que más del 75% de los autores serán externos al Comité Editorial y virtualmente ajenos a la organización editorial de la revista que es la Sociedad Científica de Estudiantes de Medicina de la Universidad Mayor de San Simón (SCEM-UMSS); el único problema que se observa en nuestro medio es la baja cantidad de artículos producidos por estudiantes del área de la salud, muchas veces por falta de conocimiento acerca de la publicación, infravaloración de los estudiantes de parte de los asesores de investigación o por falta de tiempo sumado a las prácticas médicas que realizan6; además es importante recalcar el papel de las revistas depredadoras que dañan la credibilidad de las revistas estudiantiles en general7, esto sumado a que en muchos casos se subestima el papel de los estudiantes sobre el manejo y edición de una revista científica comparándolos con revistas depredadoras que desprestigian la ciencia de pregrado8. En conclusión, el valor del escrito científico solamente puede ser medido por la calidad de sus revisiones resultado de la internacionalización de comités editoriales y “escapando” a la endogamia. Como miembros de la comunidad científica tenemos que ser objetivos con los procesos de edición y publicación de revistas sin menospreciar el rol que realizan las revistas estudiantiles en todas las partes del mundo, dicho esto invito al lector a revisar nuestras nuevas normas de publicación en las cuales añadimos aclaraciones para algunos puntos.

Introduction: The frequent complication, after spinal anesthesia in hip arthroplasty is Intraoperative Arterial Hypotension, so the need to evaluate a vasopressor that is useful for this purpose. Objectives: To evaluate the use of norepinephrine and etilefrine for the prevention for intraoperative hypotension induced by spinal anesthesia in patients undergoing total hip arthroplasty. Methods: Clinical trial, simple blind, transverse and prospective. 38 patients of both sex, age 60 to 85 years, ASA II-III, spinal anesthesia and accept to participate in the study. Exclusion criteria: age <60 and> 85 years, ASA IVV, general anesthesia, hypertension and uncontrolled heart disease. Assigned in 2 groups: group E (Etilefrine 2 mg bolus IV) and group N (Norepinephrine infusion 0.03 to 0.05 mcg / kg / min IV). The statistical analysis was performed student T. Results: Age in group E: 68 years and group N 69.94 years. Mean arterial pressure baseline (group E):74.3 mmHg, y (group N): 72.4 mmHg, Statistical significance p value <0.05 after administration of local anesthestics. In group E, the baseline heart rate is 73 beats when using ethylephrine up to 95 beats. Group N: baseline of 70 and descent of 10 beats when the norepinephrine infusion is started. The Statistical significance ( p value <0.05) in three moment (heart rate with vassopresor, durant surgery and end surgery). Conclusions: Use of norepinephrine in infusion maintains hemodynamic stability within normal ranges. There were no incidents of peripheral vasopressor use.

It’s less frequent to find before penetrating trauma to the facial region injuries to the parotid gland and Stenon duct importantly. The common causes can be weapons, contusions, iatrogenic injuries secondary to surgical procedures.Was presented a 24-year-old male patient with a clinical case of one and a half months of evolution approximately, characterized by suffering a trauma in the right mandibular angle with a beam that later was subsequently damaged and caused a sacular dilation of the Stenon conduct, which evolved to fistula of the same, who has to be performed cervical exploration surgery and salivary fistula closure and resection of the sacular dilation are performed. Obtained surgical management due to the magnitude of the damage and the time elapsed, in contrast to the new conservative approaches in which antisialogogues are administered and the closing of the wound is conservatively controlled.

Fever is a physiological reaction that involves multiple cellular and humoral components in intimate homeostatic balance. This reaction takes place in the presence of exogenous microorganisms or potentially pathogenic substances regulated mainly by the hypothalamus that involves the production and secretion of proinflammatory substances and febrigenic mediators, which determines a cascade of events that raise the body temperature. The fever is usually a controlled response, body temperature usually rises to tolerable levels for tissues. In most cases a controlled feverish reaction that unravels to tolerable tissue levels is deployed. In pathological situations this reaction can be harmful to cells, however, the organism possesses endogenous defense mechanisms that usually regulate the intensity of the fever response. This thermal modulation that protects the body from the side effects of fever is mediated by endogenous cryogens; substances with the ability to lower body temperature and in specific cases produce protective hypothermia.

Ludwig's Angina is an infectious disease that affects mainly the floor of the mouth, progressing through submandibular, sublingual and submentonian spaces, making its way to the airway, being able to cause its collapse, thus causing ventilatory failure and death. First of all, we begin with a short review of the latest literature regarding this illness. It´s presented an elderly female adult, who is brought into the emergency service with a face cellulitis diagnose. She is examined by the internist specialist on shift, who rapidly diagnoses Ludwig’s Angina, establishes broad spectrum antibiotic treatment and interconsults with the general surgery service due to possible ventilatory failure with and a hard to access air way. Thanks to the rapid and timely diagnose an adequate treatment is established and it is possible to contain this pathology without grave complications.

 In recent times women have been making their way into engineering, one of the most booming fields internationally. However, women enrollment in these careers in Mexico has grown slowly, only about 30 % of the total student population enrolled in an engineering related program are women. For the purposes of this research, a survey was applied to the students of three universities in the northwest region of Mexico confirmed a STEAM network aiming to promote enrollment, retention and gender equality on STEM careers, in order to present the outcome about their motivation for this career choice. As well as the future performance model of female students enrolled in engineering degrees. Findings have shown that there is no female model to follow, so it is proposed to include a Science, Technology, Engineering, Arts and Mathematics (STEAM) model in the Schools of Engineering to increase preference and enrollment of women in this area of knowledge.
