In this work, composite powders of aluminum alloy 7075 (AA7075) reinforced by 2 weight percent of nanosized particles of silicon carbide (SiC), titanium nitride (TiN), and zinc oxide (ZnO) were produced in a bath of isopropyl alcohol by high energy ball milling during 480 min at 25 ºC, 900 rpm, and Balls-to-Powder Weight Ratio (BPR) of 20:1. The techniques of X-Ray Diffraction (XRD), Laser Diffraction Method (LDM), Scanning Electron Microscopy (SEM), and microanalysis of Energy Dispersive Spectroscopy (EDS) were used to characterize the powders as received and processed. Then, the composites were hot extruded and characterized by XRD, SEM, and microhardness Vickers (HV). The milling process reduces the crystallite and particle size to around 30 nm and 10 µm, respectively. After extrusion, a fine microstructure and good consolidation were found for all bars, except for AA7075 as received. The ranging microhardness values were from 97 HV to 121 HV.

Abstract Introduction: The numbers of SARS-CoV-2 infection in the pediatric population are low so far. There is limited information about the behavior of SARS-CoV-2 in a pediatric patient with chronic kidney disease. Objective: To formulate informed recommendations to the prevention, diagnosis, and management of SARS-CoV-2 infection in pediatric patients with kidney disease or acute kidney injury associated with COVID-19 in Colombia. Methodology: A rapid systematic review was performed in Embase and Pubmed databases and scientific societies, to answer questions prioritized by clinical experts in pediatric nephrology. The quality of the evidence was evaluated with validated tools according to the type of study. The preliminary recommendations were consulted by an expert group. The agreement was defined when approval was obtained from at least 70% of the experts consulted. Results: A response was obtained from ' 9 experts in pediatric nephrology in Colombia, who declared the conflict of interest before the consultation. The range of agreement for the recommendations ranged from 78.9% to '00%. The recommendations did not require a second consultation. Conclusion: The evidence-based recommendations for the management of a patient with kidney disease and COVID-19 in the Colombian context are presented.

Abstract Aims: The purpose of this study is to assess the prevalence of oral and dentoalveolar trauma among contact sports practitioners in the Federal District of Brazil. Methods: A cross-sectional descriptive study was conducted using a questionnaire developed specifically for this research regarding the occurrence of facial trauma, site of injuries, how they occurred, the approach is taken to solve the problem, and the use of several types of mouthguards. Data were analyzed using the SPSS 20.0 software, and the chi-square test (X2) was chosen to examine the differences between categorical variables. The results were considered statistically significant for p<0.05. Results: A total of 141 athletes were interviewed, with a prevalence of facial trauma of 65.2%, which was higher in professional athletes (71.1%). Lesions ranged from soft tissue lacerations to combined trauma; and the most frequent injuries were soft tissue laceration (53.3%), combined trauma (16.3%), and dental fracture (9.8%). Only 20.6% of the participants required treatment for related injuries. Regarding the use of mouthguards, 34% of the athletes reported regular use of this device, and Type II mouthguard was the most used (39.7%). Dentists participate in the process of production and dissemination of mouthguards in 17.1% and 10.5% of cases, respectively. Conclusion: The data showed that most athletes are not aware of the importance of using mouthguards. The dentist must be more present in the area of sports dentistry, both for awareness and production of these devices, which support the safe practice of contact sports.

Resumen Objetivo: establecer la asociación de la insuficiencia renal aguda con los factores demográficos y clínicos en pacientes hospitalizados en la unidad de cuidados intensivos en Colombia. Métodos: estudio analítico de casos y controles cuya fuente de información fue la historia clínica del paciente, en una muestra de 130 casos y 184 controles; pacientes mayores de 18 años, que tenían una tasa de filtración glomerular mayor de 60 ml/min y que cumplían los criterios AKIN mencionar el nombre completo de la sigla. Con la prueba de independencia se estableció el efecto de los factores de interés sobre el desenlace (caso-control), con el Odds Ratio (OR) como medida de asociación con su intervalo de confianza del 95 %. La regresión logística permitió controlar las variables presumibles de confusión. Resultados: la edad promedio de los pacientes fue de 62,2 años (DE=16,7 años), hombres provenientes de la zona urbana y donde la hipertensión sobresalió en el 52,2 % de ellos. Al ingreso, el 55,7 % presentó síndrome coronario y el 40 % desarrolló insuficiencia renal aguda (IRA); el 84,6 % de los pacientes estaba en el estadio I, según la clasificación AKIN. La administración de solución salina al 0,9 % en las primeras 24 horas de ingreso incrementó la oportunidad de IRA 1,8 veces, con respecto a los que se les administró lactato de ringer (OR=1,8 IC (95 % OR: 1,2-2,8), ajustando las demás variables. Conclusión: La administración de lactato ringer disminuyó el desarrollo de la insuficiencia renal aguda. La edad de los pacientes y sus antecedentes posoperatorios, fueron los factores que se relacionaron con la presencia de IRA.

Abstract Objective: To establish the association of acute renal failure with demographic and clinical factors in patients hospitalized in an intensive care unit in a Colombian city. Methods: Analytical case-control study whose source of information was the patient's clinical history, in a sample of 130 cases and 184 controls; the cases were about patients older than 18 years, who had a glomerular filtration rate higher than 60 ml / min and who were able to fulfilled the AKIN criteria. With the independence test, it was established the effect of the factors of interest on the result (case-control), with the Odds Ratio (OR) as a measure of the association with its 95% confidence interval. The logistic regression allowed to control the presumable variables of confusion. Results: The average age of patients was 62.2 years (SD-16.7 years) with a predominance of men from the urban area and where hypertension stood out in 52.2% of them. On admission, 55.7% had coronary syndrome and 40% developed acute renal failure (ARF); 84.6% of the patients were stage according to the AKIN classification. The administration of saline in the first 24 hours of admission increased the possibility of ARF 1.8 times compared to those administered with Ringer's lactate (OR 1.8 CI (95% OR: 1.2-2.8), adjusting for other variables. Conclusion: The administration of ringer's lactate decreases the development of acute renal failure; also, age of the patient and if it came from the postoperative period, were the factors that were related to the presence of kidney disease.

Resumen La formación de concreciones calcificadas en el conducto salival o glándulas es un trastorno común, pero los cálculos de la parótida representan una pequeña parte de los cálculos salivares. Nosotros describimos este raro caso de la presencia de una fístula de piel asociada a un cálculo salivar del lóbulo superficial de la glándula parótida que foi removido sobre anestesia local. Este reporte muestra la dificultad que puede existir para establecer el diagnóstico del cálculo de la parótida. Creemos que el informe de este caso raro ayudará a los profesionales de la salud, reforzando la importancia de un diagnóstico adecuado basado en evaluaciones clínicas y de imágenes.

Abstract The formation of calcific concretions in the salivary duct or glands is a common disorder, but parotid calculi represent only a small proportion of all salivary calculi. This case describes a rare coexistence of a cutaneous fistula with salivary stones located in the superficial lobe of the parotid gland that was removed under local anesthesia. This patient provides illustration of the difficulty there may be in establishing the diagnosis of parotid calculus. We believe that the report of this rare case will help health professionals, reinforcing the importance of proper diagnosis based on clinical and imaging evaluations.

ABSTRACT: This study evaluated pre-slaughter stress and its influence on the stress indicators, quality characteristics and sensory characteristics of Nile tilapia fillets. To this end, two experiments were conducted: (1) two transportation times (60 and 240 min), with a density of 200 kg m−3, were compared to control treatment fish (in which the fish were removed from the net cage and immediately euthanized); and (2) two transportation densities (100 and 400 kg m−3), transported for 180 min, compared with control treatment fish. In experiment 1, the transportation time of 60 min resulted in higher levels of serum cortisol and plasma glucose compared to the transportation time of 240 min and the control. Fish fillets transported for 240 min had higher water-holding capacity, less water loss by pressure and higher levels of juiciness compared to fish transported for 60 min. Color, pH and water loss during cooking were not affected by transportation time. In experiment 2, transportation densities of 100 and 400 kg m−3 did not significantly affect the stress indicators nor the instrumental quality parameters of the fillets, but fish transported at 400 kg m−3 showed better visual acceptance by panellists.

ABSTRACT: Temporomandibular Disorders (TMD) is a term that was used to describe a set of pathological conditions that affect temporomandibular joint (TMJ), muscles of mastication and associated structures. Epidemiological studies estimates that 40 % to 75 % of the adult population has at least one sign of TMD, such as joint noise and 33 % presented some symptom such as facial or joint pain. Botulinum toxin is a neurotoxin produced by the anaerobic bacterium Clostridium botulinum. There are two types of toxin (A and B) used in clinical practice that were approved by Food and Drug Administration in 1989 and 2000. These medications are in use to treat various diseases including muscle spasticity, dystonia, headache and myofascial pain. The mechanisms of action were suggested in the mid-1950s, this neurotoxin seems to have an action at cholinergic synapses, causing a block in the release of acetylcholine from the nerve terminals without altering the neural conduction of the electrical signals. The synthesis and storage of acetylcholine were preserved. Intramuscular injection in appropriate doses and location causes partial chemical denervation and decreased contracture, without causing complete paralysis of muscles. Due to this features, it has been considered an innovative and effective method to treat chronic pain associated with hyperactivity of masticatory muscles. The botulinum toxin type A appears to be an alternative method for pain control present in TMDs that have myogenic etiology. The authors recommend a correct diagnosis, since the indication of this type of treatment associated with an incorrect diagnosis leads to uncertain outcomes, creating false conclusions.

RESUMEN: Los Trastornos Temporomandibulares (TTM) consisten en un conjunto de condiciones patológicas que afectan la articulación temporomandibular (ATM), los músculos de la masticación y las estructuras asociadas. Estudios epidemiológicos estiman que 40 % a 75 % de la población adulta presenta por lo menos un signo de TTM, como ruido articular y 33 % por lo menos un síntoma, como dolor facial o en la ATM. La toxina botulínica (BoNT) es una neurotoxina producida por la bacteria anaerobia Clostridium botulinum, solo la toxina A y B son utilizadas en la práctica clínica después de la aprobación de la Food and Drug Administration en 1989 y 2000; actualmente continúan siendo utilizadas para tratar varias condiciones de dolor, incluyendo la espasticidad muscular, distonia, dolor de cabeza y dolor miofascial. Las propuestas del mecanismo de acción fueron sugeridas a mediados de 1950 manifestando que esta neurotoxina posee alta afinidad con la sinapsis colinérgicas, ocasionando un bloqueo en la liberación de acetilcolina de esos terminales nerviosos, sin alterar la conducción neural de las señales eléctricas o en la síntesis de almacenamiento de acetilcolina. La inyección intramuscular en dosis y localización apropiada, provoca denervación química parcial y disminución de la contractura, sin ocasionar parálisis completa a lo que se le atribuye ser un innovador y eficaz método de tratamiento para el dolor crónico asociada con hiperactividad de los músculos masticatorios. La toxina botulínica tipo A es ser una alternativa para el control de la sintomatología dolorosa presente en los TTMs de etiología miogénica. Los autores recomiendan realizar un correcto diagnóstico, ya que la indicación de este tipo de tratamiento con diagnósticos incorrectos lleva a resultados inciertos.

RESUMEN. Objetivo: evaluar la calidad de vida y la autoestima de los pacientes con deformidades faciales en la zona nasal, la zona óculopalpebral y la región auricular, portadores de prótesis bucomaxilofaciales. Métodos: estudio descriptivo en pacientes usuarios de prótesis faciales, los cuales fueron rehabilitados en la clínica odontológica del Hospital Universitario de Brasilia en el periodo 2004-2011. La edad media de los pacientes evaluados fue de 63,8 años. Como instrumentos de recolección de datos, en esta investigación se utilizaron el cuestionario SF-36 y una encuesta que contenía la Escala Visual de Autoestima de Rosenberg ̸EPM. Resultados: el cáncer de piel fue el factor etiológico predominante (n = 4). La mayoría de los pacientes consideró que su deformidad es visible en algún grado (n = 4), y para tres de ellos este hecho interfiere negativamente en la frecuencia de visitas a sitios públicos. En la escala de autoestima se obtuvo una puntuación media de 4,6. En la evaluación de la calidad de vida utilizando el cuestionario SF-36 se obtuvieron valores como dolor (46,67) y aspectos emocionales (33,33). Conclusión: los resultados demuestran la importancia de hacer un seguimiento sistemático a estos pacientes. En la mayoría de los pacientes encuestados se identificó un aumento en la calidad de vida, así como una mayor autoestima, lo cual puede explicarse por la funcionalidad y estética desempeñada por la prótesis. Esta es una propuesta de evaluación que se llevó a cabo con el fin de estructurar programas de rehabilitación multidisciplinar.

ABSTRACT. Objective: evaluate the quality of life and self-esteem of patients with facial deformities in the nasal, oculo-palpebral, and auricular areas using bucco-maxillofacial prostheses. Methods: descriptive study in users of facial prostheses who were rehabilitated at the dental clinic of the University Hospital of Brasilia in the period 2004-2011. The average age of patients was 63.8 years. The data collection instruments were the SF-36 questionnaire and a survey containing the Rosenberg Self-Esteem/EPM scale. Results: skin cancer was the predominant etiologic factor (n = 4). Most patients think that their deformity is visible to some degree (n = 4) and for three of them this fact impacts negatively the frequency to visit public places. The self-esteem scale yielded an average score of 4.6. In evaluating the quality of life by means of the SF-36 questionnaire, there were scores like pain (46.67) and emotional aspects (33.33). Conclusion: the results demonstrate the importance of conducting systematic followups to these patients. Most surveyed patients experienced an increase in quality of life, as well as a higher self-esteem, which can be explained by the functionality and aesthetics offered by the prosthesis. This study is part of an assessment program conducted with the intention of structuring multidisciplinary rehabilitation programs.

Ectopic pregnancy is nowadays a worldwide health problem due to the incidence of pelvic inflammatory diseases caused by abortion, sexually transmitted diseases, the use of intrauterine devices and assisted reproductive techniques among others. A 38- year- old black woman came to the emergency room at the Margret Marquart Catholic Hospital of Kpando, Volta Region in Ghana with a history of vomiting, chills and abdominal pain. On physical examination, a tumor mass was found, that occupied a large part of the epigastrium, Douglas sack fundus, which was convex and painful. She has a personal pathological history of chronic anaemia and she was a carrier of HIV. She was admitted in the hospital and a laparotomy was performed. She was discharged after her satisfactory evolution.

El embarazo ectópico es en la actualidad un problema de salud a nivel mundial, atribuido el aumento de su incidencia, a las inflamaciones pélvicas provocadas por enfermedades de transmisión sexual, el aborto, uso de dispositivos intrauterinos, la aplicación de técnicas de reproducción asistida, uso de inductores de la ovulación, entre otros. Se presentó un caso de embarazo ectópico ovárico en una mujer de la raza negra de 38 años de edad, que acudió con cuadro clínico de vómitos, escalofríos y dolor abdominal al Cuerpo de Guardia del Margret Marquart Catholic Hospital en Kpando, región Volta, Ghana. Al examen físico se palpó una tumoración que ocupaba gran parte del hipogastrio, fondo de saco de Douglas abombado y doloroso. Con antecedentes patológicos personales de anemia crónica y portadora de virus de inmunodeficiencia humana (VIH). Se ingresó, se realizó laparotomía y se egresó luego de evolución satisfactoria.

Current treatments of craniosynostosis rely on the application of metal springs for cranial bone deviation. However, those metal springs demand a second surgical procedure for their removal. An attractive alternative would be the substitution of metal for bioresorbable polymers in the composition of the springs. The addition of poly(isoprene), PI, to poly(lactic-co-glycolic acid), PLGA, produces a polymeric blend with partial miscibility and distinct mechanical behavior that may benefit the patient recover. It is necessary to compare the histotoxicity of PLGA/PI to that presented by PLGA. In order to verify the histological behavior of the blend, 46 male Wistar rats (Rattus norvegicus, albino strain) underwent implantation of PLGA or PLGA/PI in the skull and were allocated into subgroups by timing of euthanasia (15, 30, 60, or 90 days). After euthanasia, the skull was removed and the histotoxicity was assessed histopathologically. The PLGA/PI blend showed greater histotoxicity in animals euthanized at 60 days, although in this period the histotoxicity of the PLGA/PI blend was similar to that of the PLGA copolymer at 15 days. Despite the instability of histological response, presented in different periods of observation, the results obtained in long-term show that the material has high potential for studies in craniosynostosis treatment.

Human Bartonellosis has an acute phase characterized by fever and hemolytic anemia, and a chronic phase with bacillary angiomatosis-like lesions. This cross-sectional pilot study evaluated the immunology patterns using pre- and post-treatment samples in patients with Human Bartonellosis. Patients between five and 60 years of age, from endemic areas in Peru, in the acute or chronic phases were included. In patients in the acute phase of Bartonellosis a state of immune peripheral tolerance should be established for persistence of the infection. Our findings were that elevation of the anti-inflammatory cytokine IL-10 and numeric abnormalities of CD4+ and CD8+ T-Lymphocyte counts correlated significantly with an unfavorable immune state. During the chronic phase, the elevated levels of IFN-γ and IL-4 observed in our series correlated with previous findings of endothelial invasion of B. henselae in animal models.

La Bartonelosis Humana, tiene una fase aguda caracterizada por fiebre y anemia hemolítica, así como una fase crónica con lesiones semejantes a angiomatosis bacilar. En un estudio transversal piloto los patrones inmunológicos en pacientes con Bartonelosis Humana fueron estudiados mediante muestras pre y post tratamiento. Pacientes entre 5 y 60 años en fase aguda y crónica fueron incluidos en área endémica del Perú. En aquellos pacientes con fase aguda, una fase de tolerancia inmunológica periférica es necesaria para la persistencia de la infección. Los hallazgos de significativa elevación de citoquina anti-inflamatoria (IL-10) y anormalidades numéricas en el recuentos de Linfocitos T CD4+ y CD8+ correlacionan con un estado inmune que favorece la infección. Durante la fase crónica, elevados niveles de INF-γ y IL-4 observados en la serie de pacientes correlacionan con previos hallazgos en modelos animales que favorecen la invasión del endotelio por B. henselae.

La introducción de la tecnología de las resinas compuestas dentro de la odontología restauradora, ha sido una de las contribuciones más significativas para la odontología en los últimos veinte años. Las ventajas de las restauraciones adheridas a la estructura dental, incluyen conservación de tejido dental sano, reducción de la microfiltración, prevención de la sensibilidad postoperatoria, refuerzo de la estructura dental y la transmisión / distribución de las fuerzas masticatorias a través de la interfase adhesiva del diente. A pesar de sus ventajas, las resinas compuestas presentan significativas deficiencias en cuanto a su desempeño, sobre todo lo relacionado con la contracción de polimerización y al estrés que esta produce en la interfase diente - restauración. Actualmente, las mejoras en las formulaciones, el desarrollo de nuevas técnicas de colocación y la optimización de sus propiedades físicas y mecánicas, han hecho la restauración de resina compuesta más confiable y predecible. El objetivo principal de este artículo fue analizar los avances en los materiales de restauración de resina compuesta, a través de una exhaustiva revisión de la literatura, donde se valoraron aspectos tales como: composición, clasificación, propiedades físicas y mecánicas, aspectos de manipulación y tendencias actuales de estos materiales.

The introduction of composite-based resin technology to restorative dentistry was one of the most significant contributions to dentistry in the last twenty year. The advantages of bonded restorations include conservation of sound tooth structure, reduction of microleakage, prevention of postoperative sensitivity, tooth reinforcement and the transmission / distribution of functional stress across the bonding interface of the tooth. Today, improvements in formulations, development of new placement techniques and the optimization of physical and mechanicals properties had made the direct composite restoration more reliable and predictable. The main objective of this article was analyzing the advances of resin composites restoration material. Trought an exhaustive literature revision. Valuing aspect as composition, classification, phisycal and mechanical properties, manipulation and current trends of this material.
