Efecto del slope tibial en la recuperación funcional, en pacientes sometidos a reconstrucción de ligamento cruzado anterior / Effect of tibial slope on functional recovery in patients undergoing anterior cruciate ligament reconstruction

Resumen: Introducción: El slope tibial (inclinación) se ha identificado como uno de los factores asociados a la falla del injerto tras una reconstrucción de ligamento cruzado anterior (LCA); sin embargo, su relación con los resultados funcionales ha sido poco estudiada. El objetivo de este estudio es determinar el efecto del slope tibial en la recuperación funcional, en pacientes sometidos a reconstrucción de LCA. Material y métodos: Se incluyeron los pacientes con lesión de LCA sometidos a reconstrucción primaria, de Mayo de 2018 a Mayo de 2019, midiendo el slope tibial y recabando los puntajes de IKDC y Lysholm. Se elaboró un análisis descriptivo de primera intención y para alcanzar los objetivos se realizó una comparativa de 25 pacientes con slope tibial normal seleccionados aleatoriamente contra 25 pacientes con slope tibial aumentado. Resultados: Se incluyeron 98 pacientes, 73 contaban con un slope tibial normal y 25 con un slope tibial aumentado. Los puntajes de IKDC y Lysholm al final del seguimiento fueron mejores en los pacientes con slope tibial normal. La falla del injerto sólo se identificó en el grupo con slope tibial aumentado. Por otro lado, al análisis comparativo con el grupo control demostró un mejor resultado funcional al final del seguimiento valorado por IKDC en el grupo con slope tibial normal. Conclusión: Los pacientes sometidos a reconstrucción de LCA y slope tibial aumentado tienen un resultado funcional inferior al año de seguimiento evaluado por IKDC en comparación con pacientes con slope tibial dentro de parámetros normales.

Abstract: Introduction: The tibial slope has been identified as one of the factors associated with graft failure after anterior cruciate ligament (ACL) reconstruction; however, its relationship with functional results has been little studied. The main purpose of this study is to determine the effect of the tibial slope on functional recovery in patients undergoing reconstruction of the anterior cruciate ligament. Material and methods: We included patients with a diagnosis of anterior cruciate ligament injury undergoing primary reconstruction, from May 2018 to May 2019, who had a complete radiographic and clinical record; also, the scores from questionnaires of the International Knee Documentation Committee (IKDC) and Lysholm scores were collected pre surgical procedures and throughout the one-year follow-up. The measurement of the tibial slope was performed in lateral knee X-rays from the electronic clinical record. A descriptive analysis of first intention was done, and to achieve the objectives, we compared 25 patients who had normal tibial slope that were selected randomly with 25 patients who had increased tibial slope. Results: A total of 98 patients were included, 73 had a normal tibial slope (equal to or less than 12 degrees) and 25 with an increased tibial slope (greater than 12 degrees), the average age in both groups was 28.43 years for the group with normal tibial slope and 28.26 for patients with increased tibial slope. Regarding the functional assessment, the IKDC and Lysholm scores at the end of the follow-up were better for patients with normal tibial slope. Graft failure was only identified in the group with increased tibial slope. On the other hand, the comparative analysis with the control group randomly selected who had normal tibial slope, showed a better functional result assessed by IKDC score at the end of the follow-up for the group with normal tibial slope. Conclusion: Patients undergoing ACL reconstruction and increased Tibial Slope have an inferior functional result at one year of follow-up assessed by IKDC, when compared with patients with normal tibial slope.

Historia de la Enfermería Pediátrica en el Hospital Infantil de México Federico Gómez / History of Pediatric Nursing at the Children´s Hospital of Mexico Federico Gomez

El cuidado otorgado a los niños tiene un lugar importante para la historia de la enfermería en México; desde la cultura azteca, se les preparaba para sus actividades futuras en el calmecac, telpuchcalli y culcalli, mientras que durante la época precortesiana la principal figura era la tlamatqui-ticitl (partera), responsable de atender a las embarazadas y a sus niños durante los primeros meses.Posteriormente se funda el Hospital de la Inmaculada Concepción (hoy Hospital de Jesús), así como centros de protección para niños indígenas, mestizos y criollos a cargo de monjes agustinos, franciscanos, dominicos y jesuitas. Vasco de Quiroga fundó una casa cuna, motivo por el cual fue llamado "protector del niño indio de América", y el arzobispo Francisco de Lorenzana y Butrón fundó la Casa de Niños Expósitos de la ciudad de México. Durante el Imperio de Maximiliano de Habsburgo, la emperatriz Carlota logró el establecimiento de una "casa de maternidad e infancia". Tiempo después se planea el primer centro de higiene infantil y se funda la Casa Cuna de Coyoacán.El 30 de abril de 1943 se funda oficialmente el Hospital Infantil de México Federico Gómez (HIMFG) e inician los cursos de enfermería pediátrica, que con el tiempo cambian para constituir la especialidad en Enfermería infantil y dar origen a la especialidad en Neonatología y Oncología.

The care of children has a relevant place in Mexico nursing history; in Aztec culture, children were prepared for their future activities in the calmecac, telpuchcalli and culcalli; in the pre-Cortesian period the main figure was the tlamatqui-ticitl (midwife), who looked after pregnant women and their newborn during the first months.Subsequently, the Hospital de la Inmaculada Concepción (nowadays Hospital de Jesús) was founded, as well as protection centers for indigenous, mestizo and criollo children administered by Augustinian, Franciscan, Dominican and Jesuit monks. Vasco de Quiroga also founded an orphanage, that earned him the title of "protector of the Indian child of America". Archbishop Francisco de Lorenzana y Butrón founded as well the Casa de Niños Expósitos in Mexico City.During the Maximilian of Habsburg Empire, empress Carlota managed to establish a "maternity and childhood home". Eventually, the first child hygiene center was planned and the Casa Cuna de Coyoacán was founded.On April 30, 1943, the Hospital Infantil de México Federico Gómez (HIMFG) was officially founded, and its pediatric nursing courses were settled, which changed over time to constitute the specialty in pediatric nursing and give rise to the specialty in neonatology and oncology.

Tratamiento de mixoma odontogénico en maxilar superior. Reporte de un caso / Treatment of odontogenic myxoma in upper maxillary. A case report

El mixoma odontogénico es una neoplasia benigna, localmente agresiva, con una baja prevalencia (frecuencia del 2% al 5% de los tumores odontogénicos) en los maxilares. Este tumor a menudo se presenta como una lesión expansiva asintomática sin cambios nerviosos sensoriales. El objetivo del presente trabajo es detallar el caso de un paciente masculino de 42 años quien acude al servicio de Cirugía Bucal y Maxilofacial del Hospital Nacional Hipólito Unanue por presentar una tumoración de crecimiento lento en maxilar superior, que fue aumentando de tamaño con el tiempo y desplazando órganos dentarios, y que se extiende al paladar duro y parte de paladar blando, el diagnóstico anatomopatológico fue de mixoma odontogénico y recibió un tratamiento radical (hemimaxilectomia) por la naturaleza agresiva del tumor. En este trabajo discutimos la presentación del mixoma odontogénico en el maxilar superior, los enfoques de trata- miento; detallando la importancia de plantear alternativas de tratamiento que permitan la reconstrucción inmediata generando la menor morbilidad posible.

Odontogenic myxoma is a locally aggressive benign neoplasm with a low prevalence (frequency 2% to 5% of odontogenic tumors) in the jaws. This tumor often presents as an asymptomatic expansive lesion without sensory nerve changes. The aim of this study is to detail the case of a 42-year-old male patient who attends the Oral and Maxillofacial Surgery service of the Hipólito Unanue National Hospital due to a slow-growing tumor in the upper jaw, which increased in size over time and displacing dental organs, and extending to the hard palate and part of the soft palate, the pathological diagnosis was odontogenic myxoma and received radical treatment (hemimaxilectomy) due to the aggressive nature of the tumor. In this work we discuss the presentation of odontogenic myxoma in the maxilla, treatment approaches; detailing the importance of proposing treatment alternatives that allow immediate reconstruction generating the least possible morbidity.

Agro-food waste employed to design and develop culture media for fungal growth

Aim: Waste from the agricultural and food industries could be used as a source of nutrients in the culture media for fungal growth and thus reduce environmental pollution and the cost of bioprocesses. In this work, it was determined if some agro-food waste can improve the mycelial growth of fungi and laccase production.Methodology: Culture media with agar and vermicompost, vermiwash, calcined pork bones or fish waste for mycelial growth of fungi were elaborated. The laccase activity of each strain grown in all culture media was also estimated. Results: Pleurotus eryngii, Lentinula edodes, Pleurotus ostreatus, Flammulina velutipes, Pleurotus citrinopileatus and Ganoderma lucidum grew in all culture media, except Lentinula edodes, obtaining in general higher biomass and radial growth rate than those observed on potato-dextrose agar. The maximum laccase activity was found in Pleurotus citrinopileatus cultivated in fish waste medium. The C: N ratio, ashes and pH were important factors for the growth of the strains. Interpretation: There were significant differences in biomass concentration and laccase activity in the designed culture media. These results provide an interesting alternative for the use of wastes and metabolites production of industrial interest.

Germination of Crotalaria and Lupinus (Fabaceae) seeds submitted to different pre-germination treatments and their effect on enzymatic activity during early germination / Germinação de sementes de Crotalaria e Lupinus (Fabaceae) submetidas a diferentes tratamentos pré-germinativos e o efeito da atividade enzimática na fase inicial da germinação

Abstract Most of the wild and native legume seeds has a hard and impermeable testa, which causes physical dormancy and prevents them from germinating even when environmental conditions are favorable. The study evaluated the effect of scarification treatments on germination and enzymatic activity of Crotalaria longirostrata (Cl) and Lupinus exaltatus (Le) seeds. After scarification treatments, germination percentage (GP) and rate (GR) were assessed during 30 days after seeding (DAS); and water absorption (WA) and specific enzymatic activity (SEA) during early germination (0, 6, 18, 36, 72, 120 h) in a growing chamber at 25 °C and photoperiod of 12 h. Scarification with 98% H2SO4 15 min increased GP and GR in both species. At 30 DAS, GP and GR of Le seeds were 34% and 0.97 seeds day-1, respectively. In Cl seeds, GP was 64% and GR 0.90 seeds day-1. Scarification with H2O at 80 °C 1 min also promoted germination in Cl (52%). At 120 h after seeding, Le and Cl seeds showed already a high GP with acid scarification (31% and 48%, respectively). In seeds of both species, scarification treatments affected WA and SEA during early germination. During this period, scarification treatments that increased GP also showed a higher α-D-galactosidase activity. The maximum enzyme activity was observed 72 h after hot water scarification in Cl (82.6 U/mg total protein), followed by acid scarification (54.5 U/mg total protein). In Le, the activity peak was 36 h after acid scarification (9.5 U/mg total protein). No relationship was observed between β-glucosidase activity and GP in both species. In conclusion, during early germination of both species, the increase in GP is accompanied by a rise in α-D-galactosidase activity between 36 and 72 h after seeding; and in Cl seeds, an alternative scarification treatment to increase GP may be the use of hot water.

Resumo A maioria das sementes de leguminosas nativas e selvagens têm um tegumento rígido e impermeável, ​​o que causa dormência física e impede a germinação, mesmo se as condições ambientais forem favoráveis. O estudo avaliou o efeito de tratamentos de escarificação sobre a germinação e a atividade enzimática de sementes de Crotalaria longirostrata (Cl) e Lupinus exaltatus (Le). Após os tratamentos de escarificação, a percentagem (PG) e a velocidade de germinação (VG) foram avaliadas durante 30 dias após a semeadura (DAS); absorção de água (AA) e atividade enzimática específica (AEE) na fase inicial da germinação (0, 6, 18, 36, 72 e 120 h) em uma câmara de crescimento a 25 °C e fotoperíodo de 12 h. A escarificação com 98% de H2SO4, durante 15 min aumentou PG e VG nas duas espécies. Aos 30 DDS, PG e VG de sementes de Le foram de 34% e 0,97 sementes dia -1, respectivamente. Em sementes de Cl, PG foi de 64% e VG 0,90 sementes dias-1. A escarificação com H2O a 80 °C 1 min também promoveu a germinação em Cl (52%). A 120 h após a semeadura, as sementes de Cl e Le já tinha atingido uma alta PG com escarificação ácida (31% e 48%, respectivamente). Nas sementes das duas espécies, os tratamentos de escarificação afetaram a AEE e a AA nafase inicial da germinação. Durante este período, os tratamentos de escarificação que aumentaram PG, também mostraram a atividade mais elevada de α-D-galactosidase. A atividade enzimática máxima foi observada 72 h após o tratamento com água quente em Cl (82,6 U/mg de proteína total), seguido por escarificação ácida (54,5 U/mg de proteína total). Em Le, o pico de atividade foi de 36 h após a aplicação do tratamento ácido (9,5 U/mg de proteína total). Em contraste, não foi observado nenhuma relação entre a actividade β-glicosidase e PG. Em conclusão, durante a germinação precoce das duas espécies, o aumento da GP é acompanhado por um aumento da atividade da α-D-galactosidase entre 36 e 72 h após a semeadura; e em sementes de Cl, um tratamento de escarificação alternativo para aumentar GP pode ser o uso de água quente.

Su diagnóstico debe ser oportuno para evitar complicaciones y secuelas irreparables, por lo que las imágenes cumplen un rol fundamental. Se realiza una revisión sobre las FT y una muestra de casos para comprender cómo se generan y así realizar un adecuado diagnóstico de ellas.

Ocupación e identidad social en personas en situación de calle de la ciudad de Punta Arenas / Occupation and identity in social status of people in city street Punta Arenas

El paradigma actual de la Terapia Ocupacional, se enmarca en “el ser y el hacer” de los individuos que enfrentan situaciones de amenaza o daño en su desempeño ocupacional. Por otra parte, la calle tiende a ganar progresivamente importancia, guiando las vidas cotidianas de las personas, así como sus relaciones personales y sociales. A través de un estudio cualitativo, descriptivo y fenomenológico, se tiene como objetivo analizar la narrativa de las personas en situación de calle (PsC) de la ciudad de Punta Arenas e identificar en ellas elementos relativos a la ocupación. El colectivo de estudio estuvo compuesto por ocho personas en situación de calle de la ciudad de Punta Arenas. Los principales hallazgos que se evidencia están relacionados a las ocupaciones, en las cuales se pudo identificar la actividad laboral realizada en el pasado y el “macheteo” como una ocupación significativa en la actualidad, en cuanto al contexto familiar destacan problemas relacionados al consumo de alcohol y violencia, los cuales desencadenaron dicha situación y al no estar resueltos permitieron repetir patrones desadaptativos los cuales interfieren significativamente en la motivación intrínseca, ya que no es la suficiente para generar el cambio y presentan aspiraciones bastantes altas con respecto a su condición actual, como el interés de un trabajo estable con el propósito de lograr estabilidad, adquirir una vivienda propia y mejorar su calidad de vida...

The current paradigm of Occupational Therapy, is part of "being and doing" of individuals facing situations of threat or harm to their occupational performance. Moreover, the street tends to progressively gain importance, guiding the daily lives of people and their personal and social relationships. Through a qualitative, descriptive and phenomenological study, it aims to analyze the narrative of People in situation streets. (SS) of the city of Punta Arenas and identify these elements relating to the Occupation. The group study consisted of eight people in street situations of the city of Punta Arenas. The main findings evidenced are related to occupations, in which it could be identified the work activity performed in the past and the "macheteo" as a significant occupation nowadays, In relation to the familiar context, it is possible to see problems related to alcohol and violence. These actions provoked this bad situation, and not being solved allowed maladaptive patterns which interfere significantly on intrinsic motivation, due to it is not enough to create a change in addition to have high aspirations regarding their real condition, such as the interest of a stable work with the purpose of achieving stability, acquire a own house and improve their quality of life...

Lobectomía en ratas: modelo quirúrgico experimental: resultados en la densidad alveolar / Development of a rat model of lung lobectomy

Introducción: En la literatura está documentado que diferentes mamíferos tienen la capacidad de crecimiento compensatorio post resección pulmonar parcial. Objetivo: Crear un modelo quirúrgico de lobectomía en ratas, factible de desarrollar en nuestro medio, exponiendo algunas originalidades en relación a procedimientos de ventilación pulmonar, comunicando los resultados de la densidad alveolar obtenidos. Animales y Métodos: Se utilizaron 47 ratas Rattus norvegicus. Se aplicó como anestesia Atropina, Quetamina y Xilacina. Para el manejo de la vía aérea se diseñó: 1. Un sistema de ventilación con máscara facial tipo ambú evitando así la intubación traqueal. 2. Un protocolo de evaluación anestésica. 3. Un halo para oxigenar. 4. Se modificó un estetoscopio para realizar auscultación animal. Se practicó una lobectomía pulmonar derecha. Los sujetos fueron separados en Grupo Control (n = 7) y Grupo Experimental (n = 40), estos últimos, separados en cuatro grupos (n = 10, cada grupo), que fueron sacrificados en las semana 1, 2, 3 y 4. Resultados: Se logró 100 por ciento de sobrevida. El número de intersecciones alveolares mostró diferencias significativas entre el grupo control y el grupo experimental sacrificado en la semana 3 (p = 0,0016), con un menor número de alvéolos en el grupo experimental. Conclusión: Es factible realizar un modelo de cirugía pulmonar en ratas, con obtención de un 100 por ciento de sobrevida. Esto se logra por adecuaciones en el manejo pre e intra-operatorio. No se pudo demostrar que exista aumento significativo en el número de alvéolos, posiblemente por el bajo número de casos realizados.

Background: Surgical lung resection is required for multiple pulmonary diseases. After these procedures, the lung experiences a compensatory growth, which can be studied in animal models such as rats. Aim: To develop a surgical model of lung lobectomy in rats. Material and Methods: Forty seven rats of the strain Rattus norvegicus were used. Animals were anesthetized with atropine, ketamine and xylacine. The airway was managed with a facial mask to avoid intubation. An anesthetic evaluation protocol was followed and animals were oxygenated using a cephalic veil. Forty rats were subjected to a right lobectomy and seven animals were sham operated. Rats subjected to lobectomy were sacrificed at one, two, three and four weeks after operation. Results: All operated rats survived. There were significant differences in the number of alveolar intersections among rats subjected to lobectomy and sacrificed at three weeks compared to sham operated animals, with a lower number of alveoli among the former. Conclusions: We were able to develop the model of lobectomy, however we failed to demonstrate a compensatory growth among rats subjected to lobectomy.

Salud bucodental de postrados severos / Oral health status of elderly bedridden

El propósito de esta investigación fue describir la salud oral en base a COP, PSR, desdentamiento, lesiones de mucosa, uso de prótesis e higiene bucal en pacientes postrados. Se realizó un estudio transversal con una muestra probabilística con afijación proporcional, según distribución geográfica y sexo, obtenida del listado de los inscritos en el Programa de Atención Domiciliaria a Postrados de la Corporación Municipal de Valparaíso. A los pacientes se les sometió a una entrevista y un examen bucodentario. Se examinaron 78 pacientes postrados severos, 64,1 por ciento mujeres y 35,9 por ciento hombres de una edad promedio 83,9 y 79,7 años respectivamente. El COP registrado fue 29,91(+/-2,52) (IC del 95 por ciento= [29,06 - 30,76]); con un índice de cariados 1,60; obturados 0,51; y perdidos, 27,79. El estado periodontal encontrado fue altamente deteriorado con 78,8 por ciento de dientes con pérdida de inserción clínica mayor a 3,5 mm, 15,2 por ciento de código 4; 36,5 por ciento de código 3; y 48,5 por ciento de código 2 de PSR. Las lesiones de tejidos blandos afectaron al 52,5 por ciento de la muestra, siendo más prevalente el tipo vascular (lago venoso) con un 25 por ciento, seguida por 23,21 por ciento de estomatitis subprotésica. El 51,3 por ciento fue desdentado total. En cuanto a distribución dentaria, en maxilar y mandíbula, el hallazgo más frecuente fue Clase I de Kennedy (50 oor ciento maxilar y 63,9 por ciento mandibular). Sólo el 43,6 por ciento usaba sus prótesis, la mayoría totales acrílicas (77,8 por ciento maxilar y 54,5 por ciento mandibular). Se encontró un estado extremadamente deteriorado de salud bucal en este grupo, con escasas posibilidades de ser recuperado, principalmente debido a las disminuidas condiciones sistémicas que presentan y a la falta de cobertura de los programas de salud bucal para estas personas.

The purpose of this study was to describe the oral health in bedridden patients on the basis of COP, PSR, toothlessness, mucosal injuries, prothesis and mouth hygiene. A transverse study with a probabilistic sample with proportional fixation, according to geographical distribution and gender, obtained of the list of the people in the Program of Domiciliary Attention to Bedridden of the Municipal Corporation of Valparaiso. The patients were interviewed and examinated. We examined 78 severely bedridden patients, 64.1 percent women and 35.9 percent men of an average age 83.9 and 79.7 years respectively. The registered COP was 29.91 (+/-2.52) (IC of 95 percent = [29.06 ­ 30.76]); with an index of decay 1.60; filled 0.51; and missing, 27.79. Periodontal condition was highly deteriorated by 78.8 percent of teeth with loss of clinical insertion larger than 3.5 mm, 15.2 percent of code 4; 36.5 percent of code 3; and 48.5 percent of code 2 of PSR. The injuries of soft tissues affected 52.5 percent of the sample, the vascular type (venous lake) being more prevalent with 25 percent, followed by 23.21 percent of denture stomatitis. 51.3 percent was completely toothless. As for distribution of the tooth, in maxilla and mandible, the most frequent finding was Kennedy´s Class I (50 percent and 63.9 percent). Only 43.6 percent was using their acrylic prostheses. We found an extremely damaged condition of oral health in this group, with small possibilities of being recovered, principally due to the diminished systemic conditions that they present and to the lack of coverage of the programs of oral health for these persons.

Resultados alejados de la cirugía reparadora de la insuficiencia mitral isquémica / Long-term results of mitral valve repair for ischemic mitral insufficiency

Background: The preferred treatment for ischemic mitral insufficiency is mitral valve repair with a prosthetic ring, because it does not deteriorate left ventricular function, allowing better immediate and long-term results. Aim: To assess long-term results of mitral annuloplasty with a prosthetic ring for ischemic mitral insufficiency. Patients and Methods: One hundred patients (68 men), with a mean age of 65.7 ± 8.6 years were included. They underwent a mitral annuloplasty with a prosthetic ring to treat ischemic mitral insufficiency, between February 1992 and May 2009. Fortyfour had a history of prior myocardial infarction and 46 had an evolving acute coronary syndrome. The inferior left ventricular wall was involved, exclusively or associated with an adjacent wall, in 72 cases. Coronary artery bypass grafts were performed in 92 patients and 32 required intra-aortic balloon pumping at some time during the peri-operative period. Results: Operative mortality was 10% (10 patients). During follow-up 30 patients died, at an average of 39 months after surgery (range: 3-142 months). Actuarial long-term survival rates at 1, 3 and 5 years were 79%, 72% and 64.5%, respectively. Trans esophageal echocardiogram performed in the operating room showed none or minimal residual mitral insufficiency in 96% of the cases. Echocardiographic follow-up was completed in 80% of the survivors; 79% of them had no or minimal mitral insufficiency. Only one patient was re-operated on due to severe mitral insufficiency and 4 required a permanent pacemaker. Conclusions: Considering the critical illness of these patients, good long-term results were observed after treatment of ischemic mitral regurgitation performing a mitral annuloplasty with a prosthetic ring.

Enfermedad periodontal como factor de riesgo para presentar resultados perinatales adversos / Periodontal disease as a risk factor for the adverse perinatal outcomes

Objetivo: Determinar si la enfermedad periodontal (EP) es un factor de riesgo que pudiera ejercer alguna influencia en la presentación de resultados perinatales adversos en la población general. Método: Estudio prospectivo de cohorte, en el cual se incluyeron 282 pacientes que acudieron al Hospital Universitario "Dr. José Eleuterio González", Monterrey, Nuevo León, México, para atención del parto. Se realizó examen dental clasificándolas como sanas o enfermas. Para el análisis estadístico se utilizó estadística descriptiva, medidas de tendencia central y de dispersión, X² y riesgo relativo (RR) para establecer asociación entre la enfermedad periodontal y las variables de estudio. Resultados: La incidencia de EP fue de 15 por ciento. La edad promedio de 22,1 años. El RR para parto prematuro fue 0,67 (IC 95 por ciento 0,19-2,33; p=0,81), preeclampsia 1,17 (IC 95 por ciento 0,45-3,02; p=0,35), ruptura prematura de membranas 0,842 (IC 95 por ciento 0,80-0,88; p=0,76), bajo peso al nacer 0,85 (IC 95 por ciento 0,33-2,51; p=0,71). Conclusión: En nuestro estudio no encontramos asociación entre pacientes con enfermedad periodontal y resultados perinatales adversos.

Objective: To determine the relationship between maternal periodontal disease and the development of adverse perinatal outcomes. Methods: A prospective cohort study was performed; 282 patients were included, who were assisted for their birth delivery at the Hospital Universitario "Dr. José Eleuterio González", Monterrey, Nuevo León, Mexico. A dental examination was done classifying them as healthy or sick. A descriptive and statistic study was done looking for the association between periodontal disease and the variables of the study were compared using X² and relative risk. Results: The incidence of periondontal disease was 15 percent. The average age was 22.1 years. The risk ratio for preterm delivery was 0.67 (CI 95 percent 0.19-2.33; p=0.81), preeclampisa 1.17 (CI 95 percent 0.45-3.02; p=0.35), premature rupture of membranes 0.842 (CI 95 percent 0.80-0.88; p=0.76), low birthweight 0.85 (CI 95 percent 0.33-2.51; p=0.71). Conclusion: No significant association was seen between periodontal disease and the adverse perinatal outcomes.

Efecto del solvente de recristalización y del tamaño de partícula sobre la humectabilidad del ibuprofeno / The effect of the solvent recrystallization and particle size on wettability of ibuprofen

El presente trabajo evalúa la humectabilidad del ibuprofeno recristalizado en etanol, metanol y hexano por el método de evaporación de solvente. Previamente se realiza una calificación operacional del goniómetro, mediante la determinación de la humectabilidad del sistema PTFE-agua, encontrándose buena precisión, representada por un coeficiente de variación de 2.49% (variabilidad total). Se obtienen hábitos cristalinos prismáticos para el ibuprofeno recristalizado en etanol y metanol, y aciculares al emplear hexano como solvente; además, en el análisis para establecer la estructura interna por difracción de rayos X, los tres productos resultan isomórficos. Se determina el ángulo de contacto para las tres formas recristalizadas en tres rangos de tamaño de partícula, encontrando que el menor valor de ángulo de contacto, es decir, la mejor humectabilidad, la presenta el ibuprofeno recristalizado en etanol, con un tamaño promedio de 120 µm, dando información sobre el tipo de forma y el tamaño de las partículas mas adecuado en la formulación de los comprimidos de esta sustancia.

Estudio de la aceptabilidad en escolares de barras de cereales formuladas con ovoalbúmina, aceite de soja y miel / Study of school children's acceptability of cereal bars formulated with ovalbumin, soy oil and honey

a formulación de barras de cereales de buen perfil nutricional dirigidas a niños, está fuertemente condicionada por su aceptación sensorial. Se realizó el estudió de la aceptabilidad en escolares de barras elaboradas con cereales (maíz, avena, arroz), germen de trigo, ovoalbúmina deshidratada como proteína de elevado Valor Biológico y aceite de soja extraído en frío como fuente de ácidos grasos poliinsaturados. Los cereales empleados fueron mayoritariamente integrales y texturizados. Se elaboraron 5 tipos de muestras: una formulada sólo con los ingredientes mencionados previamente (BC) y las otras cuatro con diferentes agregados: girasol en grano entero (BC+girasol), trocitos de chocolate (BC+chocolate), pasta de frutilla (BC+frutilla), girasol más pasas de uvas (BC+girasol+pasas). Como aglutinante se utilizó miel, aceite de soja y azúcar. El contenido proteico alcanzado fue 11,3-14,5% y para grasas totales el rango estuvo en 14,2-17,6%. La evaluación sensorial fue realizada en la semana de elaboración, participando 20 escolares entre 9 y 11 años. Se evaluó: aceptabilidad global, sabor global, sabor dulce, dureza y crocancia, utilizando una escala simplificada (1-10) y hedónica de 9 puntos, aplicándose análisis de varianza a los resultados. Cuatro muestras recibieron para todos los atributos altos puntajes (>7), siendo BC+chocolate la preferida y sin diferencia significativa entre las tres restantes (BC, BC+girasol, BC+frutilla). En cambio BC+girasol+pasas, obtuvo los menores valores debido a que el 58% de los niños rechaza las pasas de uva. Los resultados demuestran la factibilidad de formular alimentos en barra de corta vida útil dirigidas a niños, incorporando ovoalbúmina, aceite de soja, miel, cereales texturizados y grano entero.

Madeleine Leininger: un análisis de sus fundamentos teóricos / Madeleine Leininger: an analysis of its theoretical foundations

El presente artículo tiene como propósito hacer un análisis de los fundamentos teóricos de la propuesta de Madeleine Leininger, que se sustenta en dos disciplinas; Antropología y Sociología. El trabajo contiene los antecedentes biográficos de la autora, planteamientos de la antropología filosófica, social y cultural, a partir de los cuales se hacen inferencias en relación a los constructos utilizados por Leininger. Finalmente se establece que la Enfermería requiere del conocimiento del ser humano que vive dentro de una estructura social donde la cultura determina el estado de bienestar/ salud.

The present article has like intention make an analysis of the theoretical foundations of the proposal of Madeleine Leininger, that is sustained in two disciplines; Anthropology and Sociology. The work contains the biographical antecedents of the author, expositions of the philosophical, social and cultural anthropology, from which inferences in relation to the constructos used by Leininger become. Finally one settles down that the nursing requires of the knowledge of the human being who lives within a social structure where the culture determines the well-being state health.

Factores de riesgo de test de Apgar bajo en recién nacidos / Risk factors for low Apgar score in newborns

La asfixia neonatal es una causa importante de mortalidad y secuelas neurológicas. El objetivo de nuestro estudio es identificar los factores de riesgo maternos, perinatales y neonatales asociado a un Puntaje de Apgar (PA) bajo. Pacientes y Método: Se analizan los datos de 57 241 recién nacidos (RN), entre los años 1997 y 2004; los antecedentes fueron ingresados en forma prospectiva a una base de datos computacional. Se realizó un análisis multivariado con un modelo de regresión logística para identificar los factores de riesgo. Resultados: 1 167 presentaron un PA < - 3 al minuto (2,1 por ciento) y 291 presentaron además un puntaje < - 5 a los 5 minutos (0,5 por ciento). Los factores de riesgo de PA bajo estadísticamente significativos fueron: RN de muy bajo peso, malformaciones congénitas mayores, RN pequeño para la edad gestacional, RN pretérmino, embarazo de 42 semanas, expulsivo prolongado, fórceps, desprendimiento placentario y líquido amniótico con meconio. Conclusiones: En este trabajo se identifican los factores de riesgo de PA bajo en nuestra población, los cuales deben ser considerados para una adecuado manejo perinatal.
