Le pseudo kyste abdominal: une complication de la dérivation ventricule péritonéale à propos d'un cas / The abdominal pseudocyst: a complication of ventriculoperitoneal bypass about a case

Le pseudokyste abdominal est une complication rare pouvant survenir chez les sujets porteurs d'une dérivation ventriculo-péritonéale (DVP). Nous rapportons le cas d'un adolescent de 11 ans, chez qui une DVP a été réalisée pour une hydrocéphalie congénitale. Il présentait une distension abdominale progressive sans notion de troubles de transit. L'imagerie (échographie, urosacnner) a permis de mettre en évidence un épanchement péritonéal de grande abondance organisé, à paroi fine et régulière, exerçant un effet de masse sur la vessie et les uretères, responsable d'une urétérohydronéphrose bilatérale. Le bout distal du cathéter de DVP a été visualisé dans la collection

The abdominal pseudocyst is a rare complication that can occur in subjects with a ventriculoperitoneal drain (VPD). We report the case of an 11-year-old adolescent with congenital hydrocephalus antecedent, for whom a ventriculoperitoneal shunt was made. He presented a progressive abdominal distension without notion of transit disorders. Abdominal ultrasound and uroscanner revealed an organized peritoneal effusion of great abundance, thin and regular wall, exerting a mass effect on the bladder and the ureters responsible for bilateral uretero-hydronephrosis. Above all, it has made it possible to individualize the distal ventriculo-peritoneal bypass catheter projecting in the effusion

RESUMEN Introducción: los tumores de la encrucijada duodeno-bilio-pancreática o periampulares corresponden a un grupo heterogéneo de tumores. Se originan dentro de los 2 cm de la papila duodenal mayor. En los tumores irresecables, el tratamiento debe estar dirigido a la paliación más efectiva. El tratamiento quirúrgico paliativo va dirigido a resolver la obstrucción biliar, duodenal y el dolor, con el fin de optimizar la calidad de vida de los pacientes. Objetivo: describir el comportamiento del tratamiento quirúrgico paliativo de los tumores periampulares. Materiales y métodos: se realizó una investigación observacional, descriptiva y prospectiva con los pacientes con tumor periampular irresecable tributarios a tratamiento quirúrgico paliativo, en el Servicio de Cirugía General del Hospital Universitario "Comandante Faustino Pérez Hernández", en la ciudad de Matanzas, desde enero del 2010 hasta diciembre del 2019. Resultados: el tumor de páncreas fue el más representado. Todos los pacientes fueron tributarios de derivación biliar quirúrgica paliativa, sin embargo, la derivación gástrica se realizó solo con confirmación endoscópica de infiltración tumoral u obstrucción duodenal y la esplacnicectomía química, siempre que fue factible técnicamente o las condiciones del paciente lo permitieron. La hepaticoyeyunostomía en Y de ROUX fue la derivación biliar de elección. La principal complicación quirúrgica fue la sepsis provocando las muertes. Conclusiones: la paliación quirúrgica es la alternativa de elección con mejores resultados a largo plazo, en los tumores periampulares irresecables con buen estado general, lo que contribuye a una mejor calidad de vida (AU).

Variables electrocardiográficas asociadas a la aparición de eventos cardiovasculares adversos en el infarto agudo de miocardio sin elevación del segmento ST / Electrocardiographic variables associated to the occurrence of adverse cardiovascular events in non-ST elevation acute myocardial infarction

Introducción: La frecuencia de infarto agudo de miocardio sin elevación del segmento ST se está incrementando y, con ella, los resultados adversos en pacientes con enfermedad coronaria isquémica aguda. Objetivo: Identificar las variables electrocardiográficas asociadas a la aparición de eventos cardiovasculares adversos en el infarto agudo de miocardio sin elevación del segmento ST. Método: Se realizó un estudio transversal, de tipo correlacional, con 68 pacientes con infarto agudo de miocardio sin elevación del segmento ST atendidos en el Hospital Arnaldo Milián Castro, en la provincia de Villa Clara. Se estudiaron los hallazgos electrocardiográficos y eventos cardiacos adversos durante el ingreso. Se hicieron análisis bivariados para establecer la relación de ambas variables, utilizando el estadígrafo chi cuadrado y el riesgo relativo. Resultados: Los hallazgos electrocardiográficos más frecuentes fueron la inversión de la onda T (#8805; 2mm), depresión del segmento ST y el QT corregido largo mediante la fórmula de Bazzet. El 26,5 por ciento presentaron eventos cardiovasculares adversos. La depresión del segmento ST, el QT largo corregido y la elevación del segmento ST en aVR se asociaron significativamente con eventos adversos intrahospitalarios (p lt; 0,05). Conclusiones: La asociación de la depresión del segmento ST, la elevación del segmento ST en aVR y el QT largo corregido con la ocurrencia de eventos cardiovasculares adversos intrahospitalarios, sugiere que estos hallazgos se pueden tener en cuenta como posibles indicadores de evolución desfavorable en pacientes con infarto agudo de miocardio sin elevación del segmento ST(AU)

Introduction: The frequency of non-ST elevation acute myocardial infarction is on the increase, and so is the number of adverse results in patients with acute ischemic coronary disease. Objective: Identify the electrocardiographic variables associated to the occurrence of adverse cardiovascular events in non-ST elevation acute myocardial infarction. Method: A cross-sectional correlational study was conducted of 68 patients with non-ST elevation acute myocardial infarction cared for at Arnaldo Milián Castro Hospital in the province of Villa Clara. Attention was paid to electrocardiographic findings and adverse cardiac events occurring during the hospital stay. Bivariate analyses were performed to establish the relationship between the two variables, using the chi square statigram and relative risk estimation. Results: The most common electrocardiographic findings were T-wave inversion (#8805; 2 mm), ST depression and long corrected QT by Bazzet's formula. Of the total study subjects 26.5 percent had adverse cardiovascular events. ST depression, long corrected QT and ST elevation in aVR were significantly associated to in-hospital adverse events (p < 0.05). Conclusions: Association of ST depression, ST elevation in aVR and long corrected QT with the occurrence of adverse in-hospital cardiovascular events suggests that these findings may be taken into account as possible indicators of an unfavorable evolution in patients with non-ST elevation acute myocardial infarction(AU)

Introducción: El delineador de señales electrocardiográficas (ECG) multiderivación basado en la transformada wavelet posee alta resolución espacial y permite eliminar las diferencias interderivación que aparecen tradicionalmente en los métodos uniderivación. Para esto necesita de derivaciones de señales electrocardiográficas ortogonales entre sí para la obtención de un bucle espacial. Objetivo: Desarrollar métodos de ortogonalización de dos o tres derivaciones de señales electrocardiográficas que permitan la generalización del delineador multiderivación basado en la transformada wavelet en cualquier base de datos señales electrocardiográficas con más de una derivación. Métodos: Se implementaron tres métodos de ortogonalización de derivaciones de señales electrocardiográficas: ortogonalización de dos derivaciones a partir de la proyección de vectores, ortogonalización a partir de componentes principales y ortogonalización a partir del método clásico de Gram-Schmidt. Resultados: Se comparó el funcionamiento del delineador multiderivación de ECG cuando es usado cada método de ortogonalización, mediante el cálculo de la media aritmética y la desviación estándar teniendo en cuenta diferentes combinaciones de derivaciones de ambas bases de datos para cada una de las marcas analizadas. Los mejores resultados se obtuvieron con el método análisis de componentes principales y el peor comportamiento con el método de ortogonalización de dos derivaciones. Conclusiones: Los algoritmos de ortogonalización que obtuvieron los mejores resultados fueron los basados en tres derivaciones ortogonales, en la que fue ligeramente superior la descomposición en componentes principales y, por tanto, se considera el método más adecuado para la generalización del delineador multiderivación(AU)

Introduction: The wavelet transform-based multiderivation electrocardiographic (ECG) signal delineator has high spatial resolution and makes it possible to eliminate interderivation differences traditionally appearing in uniderivation methods. But this requires electrocardiographic signal derivations orthogonal to one another to obtain a spatial loop. Objective: Develop orthogonalization methods of two or three electrographic signal derivations allowing generalization of the wavelet transform-based multiderivation delineator in any electrographic signal database with more than one derivation. Methods: Three orthogonalization methods were implemented for electrocardiographic signal derivations: vector projection-based two-derivation orthogonalization, principal component-based orthogonalization, and orthogonalization based on the Gram-Schmidt classic method. Results: A comparison was performed between the operation of the ECG multiderivation delineator when used with each orthogonalization method. The comparison was based on estimation of the arithmetic mean and standard deviation bearing in mind different combinations of derivations from both databases for each of the marks analyzed. The best results were obtained with the principal component analysis method and the worst ones with the two-derivation orthogonalization method. Conclusions: The orthogonalization algorithms obtaining the best results were those based on three orthogonal derivations, in which decomposition into principal components was slightly higher. This is therefore considered to be the most appropriate method for generalization of the multiderivation delineator(AU)

Background Apocynin, a main component extracted from the root of Picrorhiza kurroa Royle, was a well-knownNADPH oxidase inhibitor and reported to have effect on lung injury, liver injury, diabetes and asthma. AN-1, anitrone derivative of apocynin, was found to exhibit significant effect on treatment of acute lung injury.Aim In order to carry out further preclinical study, it is important to reveal in vivo disposition of AN-1. A simple andrapid high-performance liquid chromatography (HPLC) method was developed to disclose the tissue distributionbehavior of AN-1 in Sprague-Dawley (SD) rats.Methods A HPLC method was developed and validated to measure the concentration of AN-1 in tissue sampleswith carbamazepine as internal standard (IS). The mobile phase consisted of water and methanol (47:53, v/v), theflow rate was 1 mL/min, and an ultraviolet (UV) detector was used at wavelength of 279 nm. The tissue distributionstudy of AN-1 was performed in Sprague-Dawley (SD) rats after a single intravenous dose of 40 mg/kg.Results The developed HPLC-UV method was of good specificity, precision (< 4%), accuracy (90-97%) and recovery(88-104%) for analysis of AN-1 in tissue samples of rats. The linear range was established over a concentrationrange 0.2-50 µg/mL (r2 > 0.998) in tissues including heart, liver, spleen, lung, kidney and brain. After administration,AN-1 was rapidly distributed in tissues and reached peak concentration with time, which showed a high distribution

Study on polysaccharide content and monosaccharide composition of Polyporus umbellatus from different production areas / 中国中药杂志

In order to provide scientific basics for exploitation and sufficient application of Polyporus umbellatus resources and study the monosaccharide composition of P. umbellatus polysaccharides,the anthrone-sulfuric acid method was applied to compare polysaccharide content of P. umbellatus from 17 producing areas. The monosaccharides were derived by 1-phenyl-3-methyl-5-pyrazolone( PMP) and the derivatives were identified by UPLC-MS/MS and the content of each monosaccharide component was determined simultaneously. The results demonstrated that there was a certain difference in total polysaccharide content of P. umbellatus from different regions,and the content of total P. umbellatus polysaccharide from Shaanxi province and Sichuan province( 1. 15% and 1. 90%) was relatively higher than that of others areas. Polysaccharides from P. umbellatus was mainly composed of eight monosaccharides,including glucose,glucuronic acid,galactose,ribose,xylose,arabinose,mannose and fucose. The contents of glucose( 17. 65 mg·g-1) was higher than others. The ribose was the lowest( 0. 13 mg·g-1). In addition,fructose,rhamnose and galacturonic acid were also detected in some samples. Furthermore,the results of cluster analysis( CA) and principal component analysis( PCA) indicated that totally 17 batches of P. umbellatus polysaccharide could be classified into three clusters,samples collected from Wuchang in Heilongjiang province were clustered into one group separately. The study can provide a basis for rational utilization of P. umbellatus resources,and also implies the sequence of monosaccharide linking and pharmacological activity of P. umbellatus polysaccharides.

Airway management through submental derivation: a safe and easily reproduced alternative for patients with complex facial trauma

OBJECTIVES: Airway management in patients with panfacial trauma is complicated. In addition to involving facial lesions, such trauma compromises the airway, and the use of intermaxillary fixation makes it difficult to secure ventilation by usual approaches (nasotracheal or endotracheal intubation). Submental airway derivation is an alternative to tracheostomy and nasotracheal intubation, allowing a permeable airway with minimal complications in complex patients. MATERIALS AND METHODS: This is a descriptive, retrospective study based on a review of medical records of all patients with facial trauma from January 2003 to May 2015. In total, 31 patients with complex factures requiring submental airway derivation were included. No complications such as bleeding, infection, vascular, glandular, or nervous lesions were presented in any of the patients. RESULTS: The use of submental airway derivation is a simple, safe, and easy method to ensure airway management. Moreover, it allows an easier reconstruction. CONCLUSION: Based on these results, we concluded that, if the relevant steps are followed, the use of submental intubation in the treatment of patients with complex facial trauma is a safe and effective option.

Content Comparison of 18 Amino Acids in Plancenta Histolysate Determined by Post-column Derivatization Cation-exchange Chromatography and Pre-column Derivatization HPLC / 中国药师

Objective:To compare the content differences of 18 amino acids in plancenta histolysate determined by pre-column de-rivatization HPLC and post-column derivatization cation-exchange chromatography ( AARO) . Methods: The HPLC method was per-formed on a C18 column and 2, 4-dinitro chlorobenzene ( DNCB) was used for pre-column derivatization, and then the determination was carried out after adding 0. 1 mol·L-1 borax buffer (pH=9. 1), and the AARO method was used for the direct determination with a strong acid cation-exchange chromatographic column and post-column derivatization. Results: The RSD for reproducibility of the AARO method was 1. 84%-0. 91%, while that of the HPLC method was 1. 87%-1. 04%. Conclusion:Both AARO method and HPLC method can be used for the quantitative determination of 18 amino acids in plancenta histolysate with the similar results. However, pre-column derivatization HPLC method may cause incomplete derivatization and instable derivatives.

EFFECT OF SIZE OF INTESTINAL DIVERSIONS IN OBESE PATIENTS WITH METABOLIC SYNDROME SUBMITTED TO GASTRIC BYPASS / EFEITO DA DIMENSÃO DAS DERIVAÇÕES INTESTINAIS EM OBESOS COM SÍNDROME METABÓLICA SUBMETIDOS AO BYPASS GÁSTRICO

ABSTRACT Background: There is no consensus on the ideal size of intestinal loops in gastric bypass of bariatric surgeries. Aim: To evaluate the metabolic outcome of patients submitted to gastric bypass with alimentary and biliopancreatic loops of different sizes. Methods: Was conducted a retrospective cohort study in diabetic obese patients (BMI≥35 kg/m2) with metabolic syndrome submitted to gastric bypass. The patients were divided into three groups according to the size of the intestinal loop: group 1, biliopancreatic limb 50 cm length and alimentary limb 100 cm length; group 2 , biliopancreatic limb 50 cm length and alimentary limb 150 cm length; and group 3, biliopancreatic limb 100 cm length and alimentary limb 150 cm length. The effect of gastric bypass with different sizes of intestinal loops in relation to the parameters that define metabolic syndrome was determined. Results: Sixty-three patients were evaluated, and they had a mean age of 44.7±9.4 years. All were diabetics, with 62 (98.4%) being hypertensive and 51 (82.2%) dyslipidemic. The three groups were homogeneous in relation to the variables. In 24 months, there was a remission of systemic arterial hypertension in 65% of patients in group 1, 62.5% in group 2 and 68.4% in group 3. Remission of diabetes occurred in 85% of patients in group 1, 83% in group 2 and 84% in group 3. There was no statistical difference in %LEW between the groups, and waist measurements decreased in a homogeneous way in all groups. The size of loops also had no influence on the improvement in dyslipidemia. Conclusion: Variation in size of intestinal loops does not appear to influence improvement in metabolic syndrome in this group of patients.

RESUMO Racional: Não há consenso sobre o tamanho ideal das alças intestinais no bypass gástrico em Y-de-Roux em cirurgias bariátricas. Objetivo: Avaliar os desfechos metabólicos de pacientes submetidos ao bypass gástrico com alça intestinal alimentar e biliopancreática de tamanhos diferentes. Métodos: Realizou-se coorte retrospectiva em pacientes obesos (IMC≥35 kg/m2) diabéticos com síndrome metabólica submetidos ao bypass gástrico em Y-de-Roux. Foram divididos em três grupos conforme a dimensão das alças intestinais: grupo 1, alça biliopancreática de 50 cm e alça alimentar de 100 cm; grupo 2, alça biliopancreática de 50 cm e alça alimentar de 150 cm e grupo 3, alça biliopancreática de 100 cm e alça alimentar de 150 cm. Foram avaliados os parâmetros que compõem a síndrome metabólica. Resultados: Incluíram-se 63 pacientes, com média de idade de 44.7±9.4 anos. Todos eram diabéticos, 62 (98.4%) hipertensos e 51 (82.2%) dislipidêmicos. Os três grupos eram homogêneos em relação às variáveis estudadas. Em 24 meses houve remissão da hipertensão arterial sistêmica em 65% do grupo 1, 62.5% no grupo 2 e 68.4% no grupo 3. A remissão do diabete melito tipo 2 ocorreu em 85% dos pacientes do grupo 1, 83% no grupo 2, e 84% no grupo 3. Não houve diferença estatística na porcentagem de perda do excesso de peso entre os grupos e as medidas da cintura abdominal reduziram de forma homogênea em todos os grupos. A dimensão das alças também não influenciou na melhora da dislipidemia. Conclusão: A variação da dimensão das alças intestinais não influenciou na melhora da síndrome metabólica neste grupo de pacientes.
