ABSTRACT

Introducción. La obstrucción intestinal es una patología de alta prevalencia. Su abordaje diagnóstico y terapéutico ha evolucionado acorde con el avance del conocimiento e implementación de la tecnología. El impacto de sus complicaciones obliga a redoblar esfuerzos en pro de lograr una mayor efectividad. Se hizo una aproximación reflexiva al problema, mediante una identificación de los puntos controversiales de interés para el cirujano general. Métodos. Se realizó una búsqueda sistemática de la literatura en varias bases de datos, utilizando dos ecuaciones de búsqueda que emplearon términos seleccionados a partir de los tesauros "Medical Subject Heading" (MeSH) y "Descriptores en Ciencias de la Salud" (DeCS). Resultados. Se recolectaron 43 artículos y a partir de ellos se construyó el texto de revisión. La identificación pronta de los posibles candidatos a cirugía, mediante un esquema diagnóstico y terapéutico, se constituye en una prioridad en el manejo de estos pacientes. De igual manera, se efectúan consideraciones en la toma de decisiones con respecto a la vía quirúrgica, así como recomendaciones técnicas operatorias producto de la experiencia y lo reportado en la literatura. Existen factores propios del cirujano, del contexto y del paciente, que inciden en la resolución del problema. Conclusión. La obstrucción intestinal y sus implicaciones clínicas obligan a una reevaluación constante de su estado del arte y avances en el manejo, tendiente a una búsqueda de oportunidades para impactar favorablemente en su curso clínico. Hay estrategias por implementar, inclusive el manejo laparoscópico en casos seleccionados


Introduction. Intestinal obstruction is a pathology of high prevalence. Its diagnostic and therapeutic approach has evolved according to the progress in knowledge and implementation of technology. The impact of its complications makes it necessary to make the efforts to achieve higher effectiveness. A reflexive approach to the problem is made by identifying the controversial points of interest for the general surgeon. Methods. A systematic literature search was carried out in several databases, using two search equations from the review performed in the thesaurus "Medical Subject Heading" (MeSH) and "Descriptors in Health Sciences" (DeCS). Results. A total of 43 articles were collected using the selected methods and the review text was constructed from them. The early identification of possible candidates for surgery, by means of a diagnostic and therapeutic algorithm, is a priority in the management of these patients. Likewise, considerations are made in decision-making regarding the laparoscopic vs. traditional approach, as well as operative technical recommendations based on experience and what has been reported in the literature. There are factors specific to the surgeon, the context and the patient that influence the resolution of the problem. Conclusion. Intestinal obstruction and its clinical implications require a constant reevaluation of the state of the art and advances in management, tending to search for opportunities to favorably impact its clinical course. There are strategies to be implemented, including laparoscopic management in selected cases

ABSTRACT

A nefropatia diabética consiste na principal causa de doença renal terminal e está associada a um risco aumentado de doença cardiovascular. O estudo dos mecanismos responsáveis pelo desenvolvimento da nefropatia diabética possui extrema importância, já que pode contribuir para o desenvolvimento de terapias mais eficazes para a prevenção e o tratamento dessa complicação. Alguns estudos têm demonstrado que os processos inflamatórios devem desempenhar um papel significativo no desenvolvimento e na progressão da nefropatia diabética. Citocinas inflamatórias, como interleucina 1, fator de necrose tumoral alfa e interleucina 6, têm sido associadas com o desenvolvimento e a evolução da disfunção renal em pacientes diabéticos tipos 1 e 2. O reconhecimento das citocinas inflamatórias como fatores patogênicos significativos da nefropatia diabética pode fornecer novos alvos terapêuticos. Neste contexto, o uso de anti-inflamatórios para o tratamento da doença renal no diabetes tem se mostrado estratégia bastante promissora


Diabetic nephropathy is the most important cause of endstage renal disease, and is associated with an increased risk of cardiovascular disease. The study of the mechanisms involved with the development of diabetic nephropathy is extremely relevant, since it can contribute to the development of more effective therapies for the prevention and treatment of this complication. Some studies have demonstrated that the inflammatory processes play a significant role in the development and progression of diabetic nephropathy. Inflammatory cytokines, such as interleukin-1, tumor necrosis factor alpha and interleukin-6, have been associated with the development and evolution of renal dysfunction in type 1 and type 2 diabetic patients. The recognition of inflammatory cytokines as significant pathogenic factors of diabetic nephropathy can provide new therapeutic targets. In this context, the use of antiinflammatories for the treatment of renal disease in diabetes has been shown to be a very promising strategy

ABSTRACT

Objetivo: Evaluar la efectividad de la profilaxis analgésica con dosis únicas de clonixinato de lisina (CL 125mg) en pacientes sometidos a extracciones dentales. Metodología: Ensayo clínico aleatorio, doble enmascaramiento placebo-controlado. Participaron pacientes ASA I y II con indicación de exodoncia dental de servicios públicos en la ciudad de Valdivia-Chile en el mes de octubre del 2012. Se asignó de manera aleatoria dos grupos: un grupo tratamiento quienes recibieron una dosis de 25mg de CL 15 minutos antes de la cirugía; y un grupo control quien recibió un placebo. A ambos grupos se indicó CL como analgésico de rescate. Mediante un cuestionario, los pacientes registraron el grado de dolor a través de una Escala Visual Análoga (EVA) durante primer día en las 7 primeras horas, después de 24 y a las 48 horas posterior a la cirugía. Además, se registró número de cápsulas de CL consumidos como rescate durante 3 días posteriores a la intervención. Se comparó el efecto analgésico observado (EVA) y el número de consumo de analgésicos adicionales entre ambos grupos mediante t-test (p<0,05). Resultados: Cincuenta y cuatro pacientes fueron intervenidos. No se encontró diferencia estadísticamente significativa entre las puntuaciones de dolor entre ambos grupos. Los pacientes con profilaxis de CL informaron similar consumo de números de cápsulas de rescate que el grupo control. Conclusión: La profilaxis analgésica con CL no demostró ser más efectiva en la reducción del dolor luego de extracciones dentales en comparación al uso de placebo y dosis postquirúrgicas.


Aim: To evaluate the effectiveness of prophylaxis with single-dose analgesic clonixinate lysine (CL 125 mg) in patients undergoing tooth extraction. Methods: A double-blind randomized placebo-controlled trial. Were included in the study patients ASA I and II with dental extraction indication in the city of Valdivia, Chile in October 2012. Were randomly assigned in two groups: the treatment group received a doses of 125mg of CL fifteen minutes before the surgery, and a control group who received placebo. Both groups used a CL as a rescue analgesic. Using a survey, patients reported the degree of pain via a visual analog scale (VAS) during the first day, at 24 and 48 hours after surgery. In addition, registered the number of CL capsules consumed as a ransom for 3 days after the surgery. We compared the analgesic effect observed in (VAS) and the number of additional analgesic consumption between the two groups using t-test (p <0,05). Results: Fifty-four patients were operated and there was no statistically significant difference between the pain scores between the two groups. Premedication patients reported the use of equal number of rescue capsules comparing with the control group. Conclusion: CL analgesic prophylaxis proved no more effective in reducing pain after tooth extraction when comparing to the use of placebo in a postoperative doses.

ABSTRACT

Objective: to describe the synthesis of analogues of furanonaphthoquinones isolated from Tabebuia genus and their inhibitory effect on nitric oxide production. Methods: a series of six derivatives were prepared through cycloaddition reactions and the products characterized by spectroscopy methods. The biological activity was evaluated measuring their effect on the pro-inflammatory mediator production in macrophages RAW 264.7 induced with lipopolysaccharides. To prevent compounds from interfering with cellular viability, their cytotoxic effect was determined using methyl tetrazolium assay. Additionally, scavenging effect was in vitro measured. Results: FNQ1, FNQ2, and FNQ5 derivatives showed potent concentration-depending inhibitory effect on nitric oxide production, with an IC50 value lower than 2 µM concentration at which they did not have toxic or scavenging effects. FNQ5 was the most active and selective derivative. Conclusions: this is the first paper concerning the anti-inflammatory potential of tested synthetic compounds. Our results indicated that FNQ5 might be considered as useful potential anti-inflammatory molecule to treat inflammatory diseases related with nitric oxide overproduction(AU)

ABSTRACT

Introducción: el manejo del dolor debe ser adaptado y optimizado de acuerdo con las condiciones de cada hospital, tipo de cirugía y paciente. Objetivos: ealuar la percepción del dolor de los pacientes intervenidos en el postoperatorio del Hospital Universitario San Jorge de Pereira. Materiales y métodos: Se realizó un estudio de corte, prospectivo en pacientes mayores de 18 años entre 2 de septiembre y 28 de octubre de 2011. La valoración de intensidad del dolor postoperatorio se realizó mediante Escala Visual Analógica a las 24 horas del postquirúrgico. Se consideraron variables sociodemográficas, clínicas (tipo de cirugía, anestesia, riesgo) y farmacológicas (medicamentos empleados, dosis, intervalos dosificación). El análisis se hizo con SPSS 20.0 para Windows. Resultados: Se evaluaron 153 pacientes en postoperatorio, 80 (52,3%) mujeres y 73 (47,7%) hombres, con edad promedio de 47,6 ± 20,2 años. El 38,8% de los pacientes no tenía controlado el dolor. Las variables de cirugía ortopédica, el empleo de anestesia general por vía intravenosa, y el incumplimiento de los intervalos recomendados de dosificación de los analgésicos, se asociaron de manera estadísticamente significativa con la falta de control. Discusión: El control del dolor fue inadecuado haciendo evidente la necesidad de replantear su manejo ajustado a guías de práctica clínica, formalizando el uso de medicamentos, en dosis e intervalos adecuados que garanticen una analgesia efectiva.


Introduction: Pain management should be adapted and optimized according to the conditions of each hospital, type of surgery and patient. Objectives: To evaluate the perception of pain in postoperative patients at Hospital Universitario San Jorge of Pereira. Materials and methods: A descriptive observational study in patients older than 18 years, between September 2nd to October 28, 2011. The assessment of postoperative pain intensity was performed by visual analogue scale 24 hours after surgery. We considered socio-demographic, clinical (type of surgery, anesthesia, risk) and pharmacological variables (drugs used, dosage, dosage intervals). The analysis was done with SPSS 20.0 for Windows. Results: We evaluated 153 patients in the postoperative period, 80 (52.3%) women and 73 (47.7%) males, mean age 47.6 ± 20.2 years. 38.8% of patients did not obtain pain control. The variables of orthopedic surgery, the use of intravenous general anesthesia, and suboptimal dosage was statistically significantly associated with lack of control. Conclusions: Pain control was inadequate thus showing the need to redefine its management by following clinical practice guidelines, through the use of analgesics in doses and appropriate intervals.

Métodos: el material vegetal se extrajo por maceración con etanol y se fraccionó mediante procedimientos de partición líquido/líquido. La actividad antiinflamatoria se evaluó utilizando el modelo murino in vivo de edema auricular inducido por 13-acetato de 12-orto-tetradecanoilforbol, mientras que la actividad antioxidante y antibacteriana se determinó in vitro, utilizando el método de captación del radical 2,2-difenil-1-picrilhidrazilo y métodos de difusión en agar, respectivamente.Resultados: los extractos etanólicos de la corteza de Tabebuia rosea y Tabebuia ochracea, así como algunas de sus fracciones, mostraron significativa actividad antiinflamatoria y antioxidante; en términos generales Tabebuia rosea resultó más activa como antiinflamatoria, mientras que en cuanto a la actividad antioxidante Tabebuia ochracea mostró ser más potente. Ambas especies de Tabebuia presentaron importante actividad antibacteriana frente a Staphylococcus aureus ATCC25923. Conclusiones: se demostró actividad antiinflamatoria, captadora de radicales libres 2,2-difenil-1-picrilhidrazilo y antibacteriana, en extractos totales y fracciones obtenidas de Tabebuia rosea y Tabebuia ochracea. Este constituye el primer reporte que valida el uso popular dado a estas especies como antiinflamatorio y antibacteriano, en la costa norte colombiana.


Introduction: Tabebuia rosea (Bertol.) A. DC. and Tabebuia ochracea (Cham.) Standl., belonging to the Bignoniaceae family, are widely used in folk medicine because of their antiinflammatory and antibacterial potentialities, all of which has prompted the chemical and biological study of these species. Objectives: to evaluate the antiinflammatory, antioxidant and antibacterial activity of the total ethanolic extracts and fractions obtained from the inner bark of Tabebuia rosea and Tabebuia ochracea by using ether, dichloromethane, ethyl acetate and ethanol. Methods: plant material was extracted through maceration with ethanol and fractionated through liquid-liquid partition method. The evaluation of antiinflammatory action used the 12-O-tetradecanoylphorbol-13-acetate induced ear edema in mice, whereas the antioxidant and antibacterial activities were determined in vitro, using the 2,22 -diphenyl-1-picrylhydrazyl radical scavenging method and agar well diffusion method, respectively. Results: ethanol extracts from Tabebuia rosea and Tabebuia ochracea inner bark, as well as some of their fractions showed significant antiinflammatory and antioxidant activity, being generally Tabebuia rosea more active as antiinflammatory. Regarding the antioxidant activity Tabebuia ochracea proved to be more potent. Both Tabebuia species revealed significant antibacterial activity against Staphylococcus aureus ATCC 25923. Conclusions: it was proven that total extracts and fractions obtained from Tabebuia rosea and Tabebuia ochracea had antiinflammatory, free radical DPPH scavenging capacity, and antibacterial activity. This is the first report which validates the popular use of these species as antiinflammatory and antibacterial agents in the north coast of Colombia.

ABSTRACT

Objective To explore the changes of etiology and mortality of upper gastrointestinal bleeding (UGIB) in the last 20 years in Guangdong region. Methods A total of 3140 UGIB cases diagnosed in Guangdong General Hospital from January 1990 to October 2009 were analyzed with retrospective analysis. Groups were divided according to admission chronological order and age to analyze the causes of UGIB to get the trend of changes and influencing factors. Results UGIB occurred more in men than in women, the gender ratio was 2. 5∶1. There was no significant change in gender composition between the first and later 10 years. Peptic ulcer bleeding (PUB) was the main cause of UGIB in young and middle-age patients (age0. 05) and esophagogastric variceal bleeding (EVB) (11. 7% vs 12. 9%, P>0.05) remained stable. The occurrence of AGML bleeding significantly increased than before (32. 4% vs 18. 8%,P<0. 01), and became one of the most important causes of UGIB. Conclusions PUB is still the most important cause of UGIB in Guangdong region. AGML becomes another important cause of UGIB in elder patients, which may relate to the increasing use of non-steroidal anti-inflammatory drugs (NSAIDs), anti-platelet and antineoplastic medicine.

ABSTRACT

Background: Adult Still's disease is an inflammatory disorder characterized by quotidian fevers, and an evanescent rash. Its presentation can be acute or subacute. Aim: To report our experience with Adult Still's disease. Material and methods: Systematic retrospective review of medical records of nine men and 11 women aged between 17 and 57 years, with Still's disease, followed in two public hospitals of Metropolitan Santiago. Results: Eighty percent of patients had a prior different diagnosis. All presented with fever and joint involvement. Eighty percent had malaise, 80 percent had odynophagia, 80 percent had an evanescent rash, 70 percent had myalgias, 50 percent had lymph node enlargement and 40 percent had splenomegaly. Laboratory showed ¡eukocytosis in 80 percent and a high erythrocyte sedimentation rate in all. High ferritin levels were detected in 80 percent, and became an important diagnosis clue. Initial treatment was based on non steroidal antiinflammatory drugs, however 80 percent required steroids and 35 percent required methotrexate. Azathioprine, sulphalazine, hydroxychloroquine and ¡eflunomide were used occasionally. Eleven patients had a single episode, nine had a relapsing disease and four had a chronic or persistent mode. Conclusions: Adult Still's disease must be suspected in patients with fever of unknown origin. An early diagnosis and adequate treatment of the disease are associated with a favorable evolution and prognosis.
