[Impact of the inclusion of articles written in English in multilingual Spanish biomedical journals]. / Impacto de la inclusión de artículos escritos en inglés en revistas biomédicas españolas de edición multilingüe.

OBJECTIVES: To analyze the impact of articles published in English compared to those published in Spanish in multilingual Spanish biomedical journals. METHODOLOGY: We analyzed the language of publication, the number of original articles, the nationality of the authors, the citations received, the citing article and the nationality of the citing authors among the articles published from 2008-2012 in 5 multilingual Spanish biomedical journals. RESULTS: The study included 4,296 documents, 85 of which were published in English (2%). The percentage of original articles and of non-Spanish authorship was significantly higher among these latter articles and they also achieved more citations and more citing articles per article published. CONCLUSIONS: The proportion of articles published in English by multilingual Spanish biomedical journals is low and they are more often originals signed exclusively by foreign authors and receive more citations than those published in Spanish, which are also more frequently made by foreign authors.

Variabilidad de la medición de la presión arterial en Pediatría. Estudio de práctica clínica / Variability of the blood pressure measurement in Pediatrics. A clinical practice study

Objetivo. Estudiar la precisión y concordancia de la medición de presión arterial en pacientes pediátricos con dispositivos aneroides y oscilométricos de uso común. Métodos. Estudio transversal de evaluación de medidas repetidas con distintos dispositivos y diferentes observadores de la presión arterial en una muestra consecutiva de 121 pacientes pediátricos mayores de 4 años ingresados. Análisis de la adecuación del tamaño del manguito empleado a las medidas de perímetro y longitud del brazo y su repercusión en la concordancia entre medidas. Estimación de medias y diferencias de medidas repetidas, coeficientes de correlación intraclase y análisis de Bland-Altman. Resultados. Las mediciones realizadas con el dispositivo oscilométrico superaron a las del aneroide (2,6 unidades para la sistólica y 1,5 para la diastólica). La diferencia entre métodos se asociaba discretamente a un desajuste con respecto al perímetro del brazo, tanto para la presión sistólica(sobreestimación media 2,55 mmHg) como para la diastólica(sobrestimación media de 2,44 mmHg). La concordancia entre medidas repetidas fue alta y aceptable entre dispositivos. Las diferencias medias y sus intervalos de concordancia fueron para la tensión sistólica de 2,6 mmHg (-8,3 a +13,5) y para la diastólica 1,5 mmHg (-11,4 a +14,4).Todas las diferencias se adecuaban al grado A de la British Hypertension Society, salvo para el criterio de 5 mmHg de la presión arterial diastólica (grado C).Conclusiones. Considerando la aceptable precisión, la facilidad de aplicación y la objetividad de los dispositivos oscilométricos parece recomendable su uso como método de cribado habitual, aunque, mientras no esté aclarada la validez de sus mediciones, si éstas se sitúan en valores anormales,deberían confirmarse con otros instrumentos (AU)

Objective. To study the reliability and consistency of measuring blood pressure in pediatric patients with aneroid and oscillometric devices of common use. Methods. A cross-sectional was carried out, with evaluation of repeated measurements of blood pressure by different devices and observers in a sample of 121 consecutive pediatric hospitalised patients over 4 years old. The adequacy of cuff size used to the measures of perimeter and length of arm and its impact on the consistency between measures were analyzed. Means and differences of repeated measurements, intraclass correlation coefficients and Bland-Altman analysis were estimated. Results. The measurements with the oscillometric device exceeded those of the aneroid (2.6 units for systolic and 1.5 for diastolic). The difference between methods was associated discreetly to a mismatch with respect to arm circumference, both for systolic pressure (mean overestimation of 2.55 mmHg) and for diastolic (mean overestimation of 2.44 mmHg). The agreement between repeated measures was high and between devices acceptable. Mean differences and their concordance intervals ranges were for systolic blood pressure of 2.6 mmHg (-8.3 to +13.5) and for diastolic 1.5 mmHg (-11.4 to 14.4). All differences were suitable for the A grade of the British Hypertension Society, except for the criterion of 5 mm Hg of the diastolic blood pressure (Grade C). Conclusions. Considering the acceptable accuracy, ease of application and the objectivity of oscillometric devices, they seem recommendable for use as a common screening method, though, while the validity of their measurements was not clarified, whether they are at abnormal levels, should be confirmed with other instruments (AU)

Self-expanding plastic stents for the treatment of post-operative esophago-jejuno anastomosis leak. A case series study.

OBJECTIVE: Self-expandable plastic stents (SEPS) are increasingly being used for treatment of postoperative esophageal leak. This complication occurs in 4-27% of patients after radical gastrectomy, and has a high mortality rate up to 60%.The aim of this study is to evaluate the efficacy of SEPS (Polyflex®) for treatment of post-operative esophago-jejuno anastomosis leak after radical gastrectomy for gastric cancer. MATERIAL AND METHODS: During one year period patients who underwent a radical gastrectomy in our hospital for gastric cancer and developed a postoperative anastomotic leak were prospectively included in the study after signing a consent form, and treated with SEPS placement under endoscopic and fluoroscopic control for leak occlusion. RESULTS: Four patients were included (3 men/1 woman). The mean interval between operation and SEPS placement was 16 days (range: 4-34). SEPS deployment was easily performed in all patients with complete occlusion of esophageal lumen in three patients. In the fourth patient we needed to deploy a second coaxial stent to achieve a complete occlusion of the fistula. SEPS migration did not happen in our series. One patient had already developed a mediastinitis by the time we placed the SEPS and he died 3 days later. Extraction of the SEPS was easily performed 4-8 weeks after deployment. CONCLUSION: We achieved a complete healing of the anastomotic fistula after radical gastrectomy in 3 out of 4 patients, without major complications related to SEPS. Placement of SEPS is an appealing minimally invasive alternative to surgical repair for patients with postoperative anastomotic leak.

Systemic disease protection elicited by plant growth promoting rhizobacteria strains: relationship between metabolic responses, systemic disease protection, and biotic elicitors.

A study of plant defensive systemic responses induced by three plant growth promoting rhizobacteria (PGPR) on Arabidopsis thaliana Col 0 against Pseudomonas syringae pv. tomato DC3000 at the biochemical and transcriptional levels is reported in this paper. All three strains decreased disease severity when applied to A. thaliana prior to pathogen inoculation. At the biochemical level, each of the three strains induced ethylene (ET) when incubated with 1-amino-cyclopropane-1-carboxylic acid, and salicylic acid (SA) production in the plant. Plants treated with each of the three strains were also reduced in salicylic acid production after pathogen challenge compared to untreated controls. This effect was more marked in plants treated with Chryseobacterium balustinum AUR9, the strain most effective in decreasing disease severity. The expression level of PR1, a transcriptional marker of the SA-dependent pathway in C. balustinum AUR9-treated plants, is fourfold that of controls while the expression of PDF1.2, a transcriptional marker for the SA-independent pathway, is not induced. C. balustinum cell wall lipopolysaccharides, being putative bacterial elicitor molecules, are able to reproduce this systemic induction effect at low doses. From these observations, we hypothesize that certain PGPR strains are capable of stimulating different systemic responses in host plants. With C. balustinum AUR9, the SA-dependent pathway is stimulated first, as indicated by increases in SA levels and PR1 expression, followed by induction of the SA-independent pathway, as indicated by the increases in ET concentrations. The effects of both pathways combined with respect to disease suppression appear to be additive.

Displasia renal multiquística segmentaria: hallazgos radiológicos y diagnóstico / diferencial / Segmental multicystic renal dysplasia: radiological findings and differential diagnosis

La displasia renal multiquística constituye la segunda causa más frecuente de masa renal en neonatos tras la hidronefrosis y la causa más frecuente de masa quística en la infancia. Presentamos un caso de una masa quística renal en un lactante cuyo diagnóstico anatomopatológicodefinitivo fue de displasia quística segmentaria. Esta entidad, en su forma segmentaria es rara, ya que habitualmente la displasia quística renal se presenta como una afectación unilateral de todo el riñón. Revisamos la etiopatogenia de esta entidad, los hallazgos radiológicos y su principal diagnóstico diferencial con el fin de establecer un correcto diagnóstico y su diferenciación con otras lesiones focales quísticas renales de la infancia

Multicystic dysplasia of the kidney is the second most common cause of renal masses in newborns after hydronephrosis and the most frequent cause of cystic masses in childhood. We present the case of acystic renal mass in an infant that was definitively diagnosed at histological examination to be segmental cystic dysplasia. Cystic renal dysplasia usually involves an entire kidney, and segmental multicystic renal dysplasia is rare. We review the etiology and pathogenesis of this entity, the radiological findings, and the main differential diagnoses with the aim of establishing the correct diagnosis and differentiatingthis entity from other focal cystic kidney lesions affecting children

Calcificaciones intracraneales. Imagen por RM / Intracranial calcifications on MRI

Objetivo. El objetivo del estudio fue demostrar la variabilidad en la apariencia de las calcificaciones intracraneales y su inespecificidad en estudios de resonancia magnética (RM) demostradas previamente por tomografía computarizada (TC). Material y método. Presentamos un estudio de 21 pacientes con lesiones intracraneales calcificadas de diferente etiología objetivadas en TC y analizamos las características de señal en RM en el seno de dichas lesiones en secuencias potenciadas en T1 y T2, tomando como referencia la corteza cerebral. Resultados. La señal de las lesiones calcificadas intracraneales fue variable. Sin embargo, la apariencia más frecuente de las calcificaciones intracraneales en estudios de RM en secuencias potenciadas en T1 fue la de áreas isointensas con la corteza cerebral. En las secuencias potencias en T2 la presentación más común de las calcificaciones fue la de focos de hipointensidad. Conclusiones. Las calcificaciones intracraneales presentan características de señal variables en las imágenes de RM, siendo su aspecto inespecífico, lo que dificulta la caracterización de lesiones intracraneales. La RM no permite excluir o demostrar con seguridad la presencia de calcificaciones. La TC es la técnica de elección para el estudio de lesiones calcificadas, por tanto, el disponer de una TC craneal en el estudio de lesiones intracraneales permite su identificación y la caracterización de dichas lesiones

Objective. The aim of this study is to show that the magnetic resonance imaging (MRI) findings for intracranial calcifications previously demonstrated at computed tomography (CT) are variable and unspecific. Material and method. We present a study of 21 patients with calcified intracranial lesions of different etiologies detected at CT. We analyze the MRI signal characteristics in these lesions in T1- and T2-weighted sequences, taking the cerebral cortex as a reference. Results. The MRI signal of the calcified intracranial lesion was variable. Nevertheless, the most frequent appearance on T1-weighted sequences was areas isointense with the cerebral cortex. The most frequent appearance on T2-weighted sequences was foci of hypointensity. Conclusions. Intracranial calcifications show variable MRI signal characteristics and have an unspecific appearance, making them difficult to characterize. MRI cannot reliably rule out or determine the presence of calcifications. CT study of intracranial lesions enables calcified lesions to be identified and characterized; therefore, CT is the technique of choice for the study of calcified lesions

[The first description of infection by Actinomyces radingae]. / Primera descripción de infección por Actinomyces radingae.

BACKGROUND: To communicate at clinical value of an isolation of Actinomyces radingae from an ulcerated lesion the external supra-malleolus region. MATERIAL AND METHODS: We proceed to study the clinical and bacteriological value of an isolated aerobic gram positive rod in pure culture obtained from an ulcerated lesion ocated at the external supra-malleolus region of a 92 years old woman in whom there was later evidence of an epidermoid carcinoma. Surgical and antibiotic treatment were needed. The biochemistry characterization of the isolated was carried out according to the schemes of Weaver-Hollis and Funke et al, as well as the characterization of the fat acids of their cellular wall by gas-liquid chromatography. RESULTS: The isolated was identified as Actinomyces radingae. The patient follow-up was satisfactory after the treatment. CONCLUSION: The first infection description by Actinomyces radingae is reported wherein its pathological value is evident as it is isolated in pure culture.

[Host plants of Bemisia tabaci (Homoptera: Aleyrodidae) in Cuba]. / Plantas hospederas de Bemisia tabaci (Homoptera: Aleyrodidae) en Cuba.

The sweet potato white fly, Bemisia tabaci, is an important pest of tomatoes and beans, among other crops, which transmits viral diseases. Since the second quarter of 1989 a significant population increase of this pest has been noted in several cultivated plants. From 1989 to 1992, a survey was done throughout the country, chiefly in vegetable and bean-producing areas. They occur in 119 species (42 families), a great increase over the previous record of four species. Worldwide, this report represents 50 species and six families which are new records.

Micropropagation of Elaeagnus angustifolia from mature trees.

Multiple shoots were obtained from nodal segments of mature trees of Elaeagnus angustifolia L. cultured on MS medium (Murashige and Skoog 1962) supplemented with 0, 0.88 or 2.22 micro M N(6)-benzyladenine. When nodal segments taken from the in vitro proliferated shoots were cultured under the same conditions, additional multiple shoots were obtained. Rooting of the in vitro propagated shoots was achieved on full strength MS medium or on MS supplemented with 2.46 micro M indole-3-butyric acid. Regenerated plantlets were acclimatized and successfully transplanted to soil.
