Artificial intelligence models and networks can learn and process dense information in a short time, leading to an efficient, objective, and accurate clinical and histopathological analysis, which can be useful to improve treatment modalities and prognostic outcomes. This paper targets oral pathologists, oral medicinists, and head and neck surgeons to provide them with a theoretical and conceptual foundation of artificial intelligence-based diagnostic approaches, with a special focus on convolutional neural networks, the state-of-the-art in artificial intelligence and deep learning.The authors conducted a literature review, and the convolutional neural network's conceptual foundations and functionality were illustrated based on a unique interdisciplinary point of view.The development of artificial intelligence-based models and computer vision methods for pattern recognition in clinical and histopathological image analysis of head and neck cancer has the potential to aid diagnosis and prognostic prediction.

Este artículo, resultado de investigación, comprende los imaginarios de familia que construyen los niños, antes y después de la separación de los padres. La metodología respondió a un paradigma cualitativo, bajo un enfoque hermenéutico, privilegiándose la narrativa como estrategia. La población estuvo compuesta por 6 niños del grado tercero y sus respectivas madres. Los resultados indican que el imaginario de familia se transforma después de la separación y que los cambios que sufre la dinámica familiar inciden en este. Se concluye que después de la ruptura de los padres, todos los miembros de la familia buscan establecer vínculos con otras personas, familia, amigos o grupos sociales para afrontar las dificultades que supone este cambio; y los padres esperan recibir apoyo de la escuela para reducir el impacto de la separación en la vida de los niños.

espanolObjetivo: el presente articulo da a conocer los resultados de una investigacion desarrollada con jovenes estudiantes de psicologia de la Universidad de Manizales entre los anos 2016-2018, que tuvo como objetivo identificar las experiencias de violencias directas, estructurales y culturales (Johan Galtung,1990) vivenciadas por los jovenes estudiantes de psicologia como testigos y sobrevivientes. Entre estas se encuentran las practicas derivadas de la guerra acontecida en el pais, teniendo presente que la mayor parte de estos jovenes colaboradores de la investigacion nacieron y vivieron su infancia en la epoca de mayor crudeza de la violencia—desde los anos 90 segun el Grupo de Memoria Historica (GMH, 2013)—. Metodologia: la investigacion fue exploratoria, de corte cualitativo hermeneutico, basado en la elaboracion de relatos. Resultados: como principales hallazgos se encontraron diversas violencias vivenciadas desde la primera infancia hasta la actualidad en espacios de confrontacion belica, tambien la exposicion a violencias intrafamiliares y escolares. Conclusion: lo anterior se complejiza al evidenciar en las narrativas estrategias de habituacion y naturalizacion de dichas violencias; procesos psicosociales necesarios de reflexionar por sus implicaciones en los desafios para la formacion, y en el ejercicio profesional posterior de los futuros psicologos y psicologas en el presente contexto para la consolidacion de la paz en Colombia. portuguesObjetivo: este artigo apresenta os resultados de uma investigacao realizada com jovens estudantes de psicologia da Universidad de Manizales entre os anos 2016-2018, que teve como objetivo identificar as experiencias de violencia direta, estrutural e cultural (Johan Galtung, 1990) vivenciadas por jovens estudantes de psicologia como testemunhas e sobreviventes. Entre elas estao as praticas derivadas da guerra ocorrida no pais, tendo em vista que a maioria desses jovens colaboradores da pesquisa nasceram e viveram sua infância no momento de maior violencia - desde a decada de 1990, segundo o Grupo de Memoria historica (GMH, 2013) -. Metodologia: a pesquisa foi exploratoria, hermeneutica qualitativa, baseada na elaboracao de historias. Resultados: como principais achados se encontraram varios tipos de violencia vivenciados desde a infância ate os dias atuais em espacos de confronto belico, bem como a exposicao a violencia intrafamiliar e escolar. Conclusao: o exposto torna-se mais complexo a medida que as narrativas revelam estrategias de habituacao e naturalizacao da referida violencia; Processos psicossociais necessarios para refletir sobre suas implicacoes nos desafios da formacao e na posterior pratica profissional dos futuros psicologos no contexto atual para a consolidacao da paz na Colombia. EnglishObjective: this article presents the results of research conducted with the participation of young psychology students of the Universidad de Manizales between 2016 and 2018. The objective was to identify direct, structural, and cultural experiences of violence (Johan Galtung, 1990) that young psychology students lived as witnesses and survivors. Among these experiences, there are practices derived from the war that took place in the country, as most of the participants were born or lived their childhood in areas of harsh violence – from the 90s according to the Historical Memory Group (GMH, 2013). Methodology: the research was exploratory, qualitatively hermeneutic and based on the construction of narratives. Results: diverse kinds of violence were found lived from early childhood to present in spaces of war confrontation and exposure to domestic and school violence. Conclusion: the complex situation is evident in the narrative strategies of habits and naturalization of such violence, the psychological processes necessary to reflect on their implications of challenges for training, and further professional work for future psychologists in the current context for the consolidation of peace in Colombia.

La artritis reumatoidea (AR) es una enfermedad inflamatoria crónica de origendesconocido, que se caracteriza por ser una poliartritis simétrica y periférica, la cual causa dañoarticular y presenta manifestaciones extraarticulares generando dolor crónico y discapacidadfísica; estas últimas deterioran la calidad de vida del paciente y provocan una percepciónnegativa sobre su bienestar físico, emocional y social [1][2]. Se realizó un estudioobservacional descriptivo a modo de reporte de caso clínico de un paciente con diagnóstico deartritis reumatoidea quien se encontraba en manejo farmacológico alopático, a pesar de estotuvo empeoramiento de su sintomatología con aumento del dolor, signos inflamatorios locales,limitación de la movilidad, cambios negativos a nivel emocional, con pérdida de la autonomía ydetrimento de la calidad de vida. Se realizó manejo con enfoque integrativo con medicamentosinmunomoduladores, multicomponentes por un periodo de 2 meses: Traumeel, Zeel T,Lymphomyosot, Nuxeel Homaccord, Berbeel Homaccord, Discus compositum, Ubichinoncompositum y Gelsemium Homaccord, los cuales fueron administrados vía oral y mediante lacombinación de técnicas como la homeosiniatria y biopuntura, además se implementaroncambios en el estilo de vida. Se realizó la aplicación de las escalas: EuroQol-5D y Escalacuantitativa numérica (ECN) durante el seguimiento del paciente, con el fin de determinar elimpacto que tiene el tratamiento a nivel de las manifestaciones clínicas y la calidad de vida. Lacalificación del dolor describió una disminución de 10/10 en ECN a 4/10 en ECN. Según eltermómetro EuroQol-5D la autovaloración de su estado de salud pasó de 20/100 a 80/100.Además, se logró reducir los requerimientos de medicamentos alopáticos. Se pudo concluir queel uso de medicamentos biorreguladores y el enfoque individual e integral del paciente logrómejoría en los signos inflamatorios y en la calidad de vida del paciente.

La pustulosis exantemática generalizada aguda es una entidad clínica poco común que, en el 90 % de los casos, se asocia con la ingestión previa de medi­camentos. Existen pocos reportes de casos de esta enfermedad de origen no me­dicamentoso; los factores desencadenantes descritos han sido virus o bacterias causantes de infecciones de las vías respiratorias superiores. Se refiere el caso de un paciente de 19 años de edad, que presentó un cuadro clí­nico de nasofaringitis y, posteriormente, pústulas superficiales en los grandes pliegues, las cuales se generalizaron. El estudio de la histopatología de la biopsia de piel indicaba una pustulosis exantemática generalizada aguda, según los cri­terios diagnósticos del estudio EuroSCAR. Debido a que no había antecedentes de consumo de medicamentos, pero sí de una infección de las vías respiratorias superiores, esta última se consideró la causa del cuadro clínico descrito.

Resumen La fitoextracción con plantas como hierba mora (Solanum nigrum L.) es una alternativa importante para la rehabilitación de suelos contaminados con cadmio (Cd). Esta especie, reconocida como hiperacumuladora, tiene capacidad para tolerar y crecer en suelos con altas concentraciones de este microelemento y constituye una alternativa de interés para los cultivadores de cacao (Theobroma cacao L.). Con el propósito de enfrentar la restricción para la comercialización de productos agrícolas que genera este elemento, se evaluó la respuesta de S. nigrum a las concentraciones de Cd: 0, 5 y 10 mg/kg en el suelo. Se halló una alta correlación entre los contenidos del elemento en el suelo y su acumulación en la planta, incrementando (P < 0.05) el área foliar (r2 = 0.63), la biomasa de la planta (r2 = 0.63) y biomasa tanto en raíz (r2 = 0.74) como en tallo (r2 = 0.47) y hojas (r2 = 0.68). Por tanto, S. nigrum L. constituye una alternativa en procesos de fitoextracción de este metal, ya que es una planta de rápido crecimiento, con bajas exigencias ambientales y alta capacidad de adaptación. Abstract An important step towards a restoration of cadmium-contaminated soils (Cd) is the use of phytoextraction, using plants such as blackberry (Solanum nigrum L.), a species reported as hyperaccumulating, capable of tolerating and developing in soils with high concentrations of Cd, which can be considered an alternative of interest for cocoa growers (Theobroma cacao L.). With the purpose of facing the restriction for the commercialization that generates this element, due to the norms of the commerce of grain, with high contents of Cd and the implications that represents in the human health, in addition, of the great number of families whose main sustenance comes from this alternative, the response of S. nigrum to three concentrations of Cd in the soil, T1: 0, T2: 5 , T3: 10 mg/kg was evaluated. It was evidenced as S. nigrum L. may be of interest for phytoextraction processes of this metal, since it is a fast growing plant, with low environmental demands and high acclimatization capacity. In this study a high correlation was found between the cadmium contents in soil and its accumulation in S. nigrum L., it was also found that the increase of cadmium in the edaphic medium favors the growth of this plant, increases the leaf area, enlarges the root biomass (r2 = 0.74 ) as well as stem and leaves in a significant way.

Objective: To identify the meanings that young students attribute to conceptions and practices of selfcare in health from a cultural approach. Methodology: The methodology addressed was qualitative from an ethnographic orientation, based on 23 in-depth interviews to young students from three basic high school education institutions in Manizales. The analysis highlights the selection of trends and the initial descriptive codes, which gave place to subcategories and categories that, nurtured the construction of meanings that participants attribute to conceptions and practices face up to self-care in health. Results: The meanings conceived as a symbolic construction that participants attribute to self-care in health were described from their heterogeneity, because the conceptions and practices arise from the cultural. Self-care of health is perceived as a family matter, from a perspective of co-responsibility and parental support. The emergence of the category of work as a practice stresses the subjective world of youth, generating contradictions, motivations, expectations and new subjective meanings. However, the nature of these works in precarious circumstances shows the difficulties in their material, social, cultural and symbolic conditions of life. Conclusions: The participants construct the meanings of self-care in health from the mobilization of knowledge and practices from the ideal of family matter, seen as parental support. The emergent category of work is a producer of new meanings, those that reveal precarious material, social and symbolic conditions associated with the youthful experiential connection.

In this work, the preliminary study about the use of secondary lead smelting slag (SLSS) as an addition to Portland cement is presented. SLSS is a waste from a Colombian secondary lead smelter. The chemical, physical and mineralogical characteristics of the raw materials were evaluated by X-ray fluorescence, particle size and X-ray diffraction. To assess the SLSS pozzolanic activity, the ASTM C618 standards were used. Additionally, cement pastes added with SLSS as Portland cement replacement in proportions of 0, 5, 10, 20 and 30% were prepared, to study the hydration process at 7, 14 and 28 of curing times. To determine the hydration products the technique of X-ray diffraction was used. Furthermore, the environmental test TCLP (Toxicity Characteristic Leaching Procedure) was performed in pastes with 28 days of curing time. Results showed that SLSS reported an index of pozzolanic activity of 87%, this value meets the standard (greater than 75%). The hydration process showed that since early curing time the waste presented a good reactivity. TCLP results satisfied the environmental standards. The outcomes showed that this waste could be used as a partial replacement of Portland cement.

Background: Idiopathic calcinosis cutis is an uncommon form of calcinosis cutis. It may present as tumoral calcinosis, subepidermal calcified nodules or scrotal calcinosis. Subepidermal calcified nodules may also present as milia-like lesions commonly seen in children with Down's syndrome in the absence of tissue damage or metabolic disorders, it has been seldom reported in adults. The treatment of choice is surgical excision. However, a surgical approach may not always be beneficial to the patient given the cosmetic outcomes. Here, we describe the successful use of a CO2 laser in the treatment of milia-like calcinosis cutis of the forehead in an adult without Down's syndrome. Aims: To describe the treatment of Milia-like idiopathic calcinosis cutis of the forehead in an adult without Down's syndrome successfully treated with a CO2 laser. Methods: We report a case of a 48-year-old man who presented with skin-colored hard asymptomatic papules on the forehead that started about 9 years ago, a biopsy was performed and a diagnosis of milialike calcinosis cutis was made. Surgical excision was discarded regarding the location and the number of lesions, instead, a CO2 laser was used to treat this condition. Results: Successful laser excision of the lesions with appealing cosmetic results. Conclusions: CO2 laser seems to be a valuable tool to treat milia-like calcinosis cutis lesions. © 2019 Wiley Periodicals, Inc.

To compare college and non-college women in terms of the frequency of, etiology of, and risk factors associated with urinary tract infections.This was a cross-sectional study conducted in Cartagena, Colombia, with 258 female college students and 256 female non-college students from 15 to 34 years old. The participants were interviewed and completed a questionnaire assessing the risk factors associated with urinary tract infections. Urine samples were examined by urinalysis and to look for signs of urinary tract infection, when found, were confirmed by culture. Isolated bacteria were tested for antimicrobial susceptibility using the Kirby-Bauer test. A chi-square test and binary logistic regression were used to analyze the data.Urinary tract infections were found in 7.8% of the participating college women and 9.4% of the participating non-college women. E. coli was the most frequent uropathogen found in the members of the 2 groups. The majority of the isolated bacteria were highly resistant to β-lactams. Binary logistic regression analysis showed that in the college women, the predictor variables of having a urinary tract infection were the presence of nitrites, leucocytes, and urinary urgency. In the case of the non-college women, the predictor variables were the presence of nitrites and cystitis in the last 2 years.The frequencies of urinary tract infection were similar in both groups. These individuals might have been taking non-prescribed antibiotics or failing to comply with a prescribed treatment or bacteria are of hospital origin.
