Efectos de las medidas de restricción sobre la actividad física y conducta sedentaria de niños, niñas y adolescentes durante la pandemia por COVID-19: revisión sistemática / Effects of restriction measures on physical activity and sedentary behavior of children and adolescents during COVID-19 pandemic: a systematic review

Introducción: La pandemia por COVID-19 obligó a los gobiernos a implementar medidas de restricción social para proteger la salud de la población, afectando la calidad de vida de las personas, especialmente en grupos vulnerables como los niños, niñas y adolescentes (NNA). El objetivo de esta revisión sistemática (RS) fue evaluar el efecto de las medidas de restricción sobre la actividad física (AF) y conducta sedentaria (CS) de los NNA. Adicionalmente, se exploraron posibles factores determinantes de estos cambios. Métodos: Se realizó una RS, utilizando tres bases de datos. Se incluyeron estudios observacionales en donde se hubiera analizado la AF y CS de los participantes, utilizando cualquier método de evaluación. Dos investigadores analizaron los estudios, extrajeron los datos y evaluaron la calidad metodológica de los artículos primarios. El metaanálisis se realizó utilizando el modelo de efectos aleatorios, considerando un valor p < 0,05 como estadísticamente significativo. Resultados: Se incluyeron 19 artículos, con una muestra total de 15.095 NNA. La mayoría de los estudios reveló una reducción de la AF y un incremento de la CS en los sujetos, durante los confinamientos por COVID-19. El metaanálisis mostró una caída en la AF total, la AF moderada a vigorosa y un incremento del tiempo de sedentarismo. Diversos factores biodemográficos, familiares y ambientales exacerbaron las variaciones en la AF y la CS de los NNA. Conclusión: Las medidas de restricción aplicadas durante pandemia por COVID-19 redujo la AF e incrementó la CS de los NNA. Factores biodemográficos, familiares y ambientales determinaron estas variaciones.

Introduction: The COVID-19 pandemic forced governments to implement social restriction measures to protect the health of the population, affecting the quality of life of people, especially in vulnerable groups, such as children and adolescents (CA). The objective of this systematic review (SR) was to evaluate the effect of restriction measures on physical activity (PA) and sedentary behavior (SB) of CA. Additionally, possible determining factors of these changes were explored. Methods: An SR was carried out, using three databases. Observational studies were included in which the PA and SB of the participants were analyzed, using any evaluation method. Two investigators analyzed the studies, extracted data, and assessed the methodological quality of the primary articles. The meta-analysis was performed using the random effects model, considering a value of p < 0.05 as statistically significant. Results: 19 articles were included, with a total sample of 15,095 subjects. Most studies revealed a reduction in PA and an increase in SB in subjects during COVID-19 lockdowns. The meta-analysis showed a drop in total PA, moderate to vigorous PA, and an increase in sedentary time. Various biodemographic, family and environmental factors exacerbated the variations in the PA and SB of the CA. Conclusion: The restriction measures applied during the COVID-19 pandemic reduced the PA and increased the SB of the CA. Biodemographic, family and environmental factors determined these variations.

Asociación entre neuroimagen y secuelas neurológicas en pacientes con infección congénita por citomegalovirus / Association between neuroimaging findings and neurological sequelae in patients with congenital cytomegalovirus infection

Introducción: La infección congénita por citomegalovirus (CMV) supone una importante causa de discapacidad. Existen escasas evidencias acerca del valor pronóstico de las lesiones presentes en los estudios de neuroimagen. Objetivo: Analizar la gravedad de las lesiones en la resonancia magnética (RM) y la ecografía transfontanelar, y su relación con déficits neurológicos a largo plazo. Pacientes y métodos: Se realizó un estudio observacional analítico retrospectivo de 36 pacientes con infección congénita por CMV. Se revisaron los estudios de neuroimagen y se clasificaron según la escala de Noyola et al. modificada. Se relacionaron los hallazgos de neuroimagen con la afectación neurológica en su última visita en la consulta de neuropediatría. Resultados: Un total de 36 pacientes fueron estudiados, habiéndose realizado ecografía transfontanelar en 30 y RM cerebral en 29. La ecografía transfontanelar estuvo alterada en 20/30 pacientes, de los cuales, 11 tuvieron alteración en la RM (p = 0,04) y 10 afectación neurológica (p = 0,008). Tuvo una sensibilidad del 83,3%, IC 90%: 58-100 y una especificidad del 44,4%, IC 90%: 18,7-70,2 para la predicción de secuelas neurológicas. La RM estuvo alterada en 20/29 pacientes. Dieciséis de ellos tuvieron afectación neurológica (p < 0,001), teniendo una sensibilidad del 94%, IC 95%: 80-100 y una especificidad del 66,6%, IC 95%: 36-97,5 para la predicción de secuelas neurológicas. Una escala de Noyola et al. ≥ 2 se asoció a retraso psicomotor (p < 0,001). Conclusión: Nuestro trabajo valida los estudios previos en los que se encuentra correlación estadísticamente significativa entre la extensión de las lesiones en neuroimagen y la gravedad de los déficits neurológicos.

Background: Congenital cytomegalovirus (CMV) infection is an important cause of disability. There is little evidence on the prognostic value of lesions identified in neuroimaging studies. Aim: The study aimed to assess the severity of lesions detected with brain MRI and transfontanellar ultrasound and their relationship with long-term neurological deficits. Patients and methods: We performed a retrospective, analytical, observational study of 36 patients with congenital CMV infection. Neuroimaging studies were reviewed and classified according to the modified Noyola’ scale. Imaging findings were compared with neurological alterations in the patients’ most recent follow-up evaluation at the paediatric neurology department. Results: Thirty-six patients were studied (transfontanellar ultrasound: 30; brain MRI: 29). Twenty of 30 patients showed ultrasound abnormalities; of these, 11 showed alterations on brain MR images (P=.04) and 10 had neurological impairment (P=.008). Transfontanellar ultrasound had a sensitivity of 83.3%, 90% CI: 58-100 and a specificity of 44.4%, 90% CI: 18.7-70.2 for predicting neurological sequelae. Brain MRI displayed abnormalities in 20 of 29 patients, of whom 16 had neurological impairment (P<.001). MRI had a sensitivity of 94%, 95% CI: 80-100 and a specificity of 66.6%, 95% CI: 36-97.5 for predicting neurological sequelae. Modified Noyola’ scale values >2 were correlated with psychomotor retardation (P<.001). Conclusions: Our findings validate previous studies reporting a statistical significant correlation between the extension of neuroimaging lesions and severity of neurological deficits. (AU)

[Cardiac Magnetic Resonance in long term follow-up of Tetralogy of Fallot]. / Resonancia magnética cardíaca en el seguimiento alejado de pacientes con tetralogía de Fallot.

INTRODUCTION: Tetralogy of Fallot (TOF) is the most frequent cyanotic congenital heart disease. Pulmonary regurgitation (PR) and right ventricle (RV) enlargement and dysfunction are the most common long-term complications. Cardiac magnetic resonance (CMR) is the gold standard for RV evaluation. OBJECTIVE: To analyze CMR results in the follow-up of TOF patients. PATIENTS AND METHOD: All CMR performed between 2007 and 2012 in TOF patients with transannular patch (TAP) repair or infundibular widening, and without pulmonary valve replacement (PVR) were included. Pulmonary regurgitant fraction (PRF), ventricular end-diastolic (EDV) and end-systolic volume (ESV), and ejection fraction (EF) were examined. RESULTS: 122 CMR were performed in 114 patients. Average age at CMR was 15.4±7.4 years. 53.3% of them presented severe PR (> 40%). RVEDV was 157.3 ± 38.6 ml/m2, RVESV was 85.3 ± 27 ml/m2 and RVEF was 46.4 ± 7.1%. RVEDV was > 150 ml/ m2 in 48.4% and > 170 ml/m2 in 32.8% of patients. Patients with TAP showed larger RV volumes compared with those with infundibular widening. RVEDV > 170 ml/m2 showed worse RVEF that those with lower RVEDV (47.9 ± 7% vs 43.2 ± 6.4%, p < 0.01). CONCLUSION: Almost half of the pa tients showed significant RV enlargement, demonstrating that the indication of CMR is late in their follow-up. TAP was associated with higher RVEDV and RVESV, but no worse RVEF.

Resonancia magnética cardíaca en el seguimiento alejado de pacientes con tetralogía de Fallot / Cardiac Magnetic Resonance in long term follow-up of Tetralogy of Fallot

INTRODUCCIÓN: La tetralogía de Fallot (TF) es la cardiopatía congénita cianótica más frecuente. La insuficiencia pulmonar (IP) y dilatación del ventrículo derecho (VD) son las complicaciones más frecuentes a largo plazo. La resonancia magnética cardiaca (RMC) es el "gold standard" para la evaluación del VD. OBJETIVO: Analizar la información obtenida de las RMC en el seguimiento de pacientes con TF. PACIENTES Y MÉTODO: Se incluyeron RMC realizadas entre 2007 y 2012 a pacientes con TF, reparados con parche transanular (PTA) o ampliación infundibular (AInf) y sin recambio valvular pulmonar (RVP). La fracción de regurgitación pulmonar (FRP), el volumen y función ventricular fueron evaluados. RESULTADOS: Se realizaron 122 RMC a 114 pacientes. Edad promedio al examen 15,4 ± 7,4 años. 53,3% presentó IP severa (> 40%). La media del volumen de fin de diástole del VD (VFDVD) fue 157,3 ± 38,6 ml/m2, fin de sístole (VFSVD) de 85,3 ± 27 ml/m2 y fracción de eyección (FEVD) 46,4 ± 7,1%. 48,4% presentaba un VFDVD mayor de 150 ml/m2 y el 32,8% mayor a 170 ml/ m2. El PTA se relacionó con mayores volúmenes de VD que la AInf. VFDVD mayor a 170 ml/m2 mostraron peor FEVD (FEVD 47,9 ± 7% vs 43,2 ± 6,4%, p < 0,01). DISCUSIÓN: Casi la mitad mostró una significativa dilatación del VD demostrando que la indicación de RMC es tardía en el seguimiento. El PTA se asoció con mayores VFDVD y VFSVD pero no a peor FEVD.

Ictus isquémico en niños con cardiopatía: estudio epidemiológico / Ischaemic stroke in children with cardiopathy: An epidemiological study

Introducción: Los ictus isquémicos son poco frecuentes en la infancia. Las cardiopatías tanto congénitas como adquiridas son uno de los factores de riesgo más importante para presentar un ictus en la edad pediátrica. Pacientes y métodos: Estudio retrospectivo descriptivo de niños con cardiopatía diagnosticados de ictus arterial isquémico entre enero del 2000 y diciembre del 2014. Resultados: Cumplieron los criterios de inclusión 74 pacientes, el 60% varones. La mediana de edad del ictus fue de 11 meses. Fallecieron un 20% de los pacientes. La cardiopatía era congénita en un 90%, cianógena en un 60%. El ventrículo izquierdo hipoplásico fue la cardiopatía más frecuente. El ictus estuvo relacionado temporalmente con una cirugía cardiaca, cateterismo o asistencia ventricular en el 70% de los casos. La mayoría de los ictus ocurrieron en el hospital. La forma de presentación más frecuente fue el déficit motor y las convulsiones. El diagnóstico se realizó mediante TC craneal en la mayoría de los casos. El ictus fue múltiple en el 33% de los casos y bihemisférico en el 27%, y afectaba a la circulación anterior y posterior cerebral en el 10%. En un 10% de los casos se produjo una recurrencia del ictus. Conclusiones: Las cardiopatías congénitas complejas y las intervenciones cardiacas, la cirugía y los cateterismos fueron los principales factores asociados con el ictus isquémico. El ictus se produjo en pacientes hospitalizados y el diagnóstico se realizó en las primeras 24 h en la mayoría de los pacientes (AU)

Introduction: Ischaemic stroke is rare during childhood. Congenital and acquired heart diseases are one of the most important risk factors for arterial ischaemic stroke (AIS) in children. Patients and methods: We conducted a retrospective study of all children with AIS and heart disease diagnosed between 2000 and 2014. Results:We included 74 children with heart disease who were eligible for inclusion. 60% were boys with a mean stroke age of 11 months. 20% of the patients died during the study period. 90% of the patients had a congenital heart disease, while cyanotic heart disease was identified in 60%. Hypoplastic left heart syndrome was the most frequent heart disease. In 70% of patients AIS was directly associated with heart surgery, catheterisation or ventricular assist devices. Most patients with AIS were in the hospital. Seizures and motor deficit were the most frequent symptoms. Most patient diagnoses were confirmed by brain CT. The AIS consisted of multiple infarcts in 33% of the cases, affected both hemispheres in 27%, and involved the anterior and posterior cerebral circulation in 10%. Conclusions: Arterial ischaemic strokes were mainly associated with complex congenital heart diseases, and heart procedures and surgery (catheterisation). AIS presented when patients were in-hospital and most of the patients were diagnosed in the first 24hours (AU)

Invasive alien species water hyacinth Eichhornia crassipes as abode for macroinvertebrates in hypertrophic Ramsar Site, Lake Xochimilco, Mexico.

This paper presents information on the density, diversity and functional feeding groups of macroinvertebrate assemblages associated with water hyacinth in Antiguo Canal Cuemanco, part of Lake Xochimilco in Mexico City. Rare (low frequency and density) and dominant (high frequency and density) taxa prevailed in the assemblages, with the most predominant being Hyalella azteca, Chironomus plumosus and Ischnura denticollis. Nonmetric Multidimensional Scaling confirmed two climatic seasons: warm-rainy and cold-dry; the former with the highest diversity and density of taxa. Canonical Correspondence Analysis showed that conductivity, nitrates and turbidity explained the density variations of taxa. Antiguo Canal Cuemanco waters are spatially homogeneous with the characteristics of hypertrophic shallow lakes, inhabited by scrapers and gathering-collectors. The species found were tolerant to organic pollution.

[Visuospatial functions and prematurity]. / Funciones visuoespaciales y prematuridad.

Visuospatial functions are very important in learning process and development of abstract thought during childhood. Several studies show that preterm and low birth weight infants obtain lower scores in test that assess cognitive functions, specially in the first year of life. These differences are attenuated over time, but a developmental delay that affects working memory and visuospatial process still persists. It is unclear what factors are involved in development of these functions, and pre- or perinatal factors may interfere with the proper conduct of the same, but have been described anatomical and physiological differences between the preterm and term brain that could explain somewhere in these alterations. The different selective vulnerability to hypoxia between immature brain in which preoligodendrocytes and subplate neurons predominate, and mature brain, determine differences in the pattern of injury from hypoxia with greater involvement of the periventricular white matter in preterm children. This lesional pattern leaves to a dysfunction in attentional and visuospatial process, due to the increased vulnerability of the regions involved in the dorsal pathway of visual processing.

TITLE: Funciones visuoespaciales y prematuridad.Durante la infancia, las funciones visuoespaciales son importantes en los procesos de aprendizaje y en el desarrollo del pensamiento abstracto. Diferentes estudios muestran que los niños prematuros o con bajo peso al nacer obtienen menores puntuaciones en los tests que valoran las funciones cognitivas, siendo estas diferencias mas pronunciadas durante el primer año de vida. Con el tiempo, estas diferencias se van atenuando, pero persiste un retraso madurativo que afecta a la memoria de trabajo y a los procesos visuoespaciales. No esta claro cuales son los factores implicados en el desarrollo de estas funciones y que factores pre o perinatales pueden interferir en su buen desarrollo, pero se han descrito diferencias anatomicas y fisiologicas entre el cerebro del niño pretermino y el termino que podrian explicar, en parte, alguna de estas alteraciones. La diferente vulnerabilidad selectiva a la hipoxia entre el cerebro inmaduro, en el que predominan las neuronas de la subplaca y los preoligodendrocitos, y el cerebro maduro del niño nacido a termino determinan diferencias en el patron de lesion por hipoxia con mayor afectacion de la sustancia blanca periventricular en el niño pretermino. Este patron lesional conlleva una disfuncion en los procesos atencionales y visuoespaciales debido a la mayor vulnerabilidad de las regiones que intervienen en la ruta dorsal del procesamiento visual.

Impacto de la intervención farmacéutica en la adherencia al tratamiento antirretroviral en pacientes de un hospital de Lima (Perú) / Pharmacist intervention in the improvement of adherence in HIV/AIDS patients with antiretroviral treatment in Lima (Peru)

Introducción: La atención farmacéutica mejora la adherencia del paciente al tratamiento, por lo que es necesario que el farmacéutico cuente con instrumentos para evaluarla y mejorarla mediante su intervención en el seguimiento farmacoterapéutico (SFT). Objetivos: Evaluar el impacto de la intervención farmacéutica en la mejora de la adherencia de los pacientes con virus de la inmunodeficiencia humana (VIH) y sida, e identificar los factores que influyen en ella y que pueden ser modificados por la intervención farmacéutica en el SFT. Métodos: Se realizó SFT durante 23 meses a 52 pacientes mayores de 18 años de edad, con tratamiento antirretroviral durante más de 3 meses, que dieron su consentimiento informado. La adherencia se evaluó con el CEAT-VIH (cuestionario para evaluar la adhesión al tratamiento antirretroviral) al inicio y al final de 6 meses de SFT. Resultados: La puntuación total del CEAT-VIH (p <0,05; intervalo de confianza del 95%), el cumplimiento del tratamiento (p <0,001) y la percepción del paciente respecto a su enfermedad y tratamiento antirretroviral (p <0,001) incrementaron significativamente su valor. La educación al paciente para incrementar la adherencia al tratamiento (46%) fue la intervención farmacéutica más frecuente. Conclusiones: Se demuestra que la intervención del farmacéutico, mediante el SFT, mejora la adherencia al tratamiento antirretroviral. El farmacéutico mejoró los aspectos de cumplimiento y percepción del paciente sobre su tratamiento y enfermedad. Los farmacéuticos pueden utilizar el CEAT-VIH como instrumento para evaluar la adherencia en la práctica del SFT (AU)

Introduction: Pharmaceutical care improves medication adherence that is why is important that the pharmacist uses instruments to evaluate and improves it through pharmaceutical intervention at pharmaceutical care. Objective: To evaluate the impact of the pharmaceutical intervention in the improvement of the medication adherence of the patients with HIV and AIDS, and to identify the factors that influence on medication adherence and which one could be modified by the pharmaceutical intervention during pharmaceutical care. Methods: Pharmacotherapeutic follow-up was realized for 23 months to 52 patients, older than 18 years, with antiretroviral treatment for up to three months, consent informed was obtained from patients. Medication adherence was evaluated with CEAT-HIV (questionnaire to evaluate the adhesion to the antiretroviral treatment) at the beginning and at the end of the study (6 months). Results: The final score from CEAT-HIV (p <0.05; 95% IC), treatment compliance (p <0.001) and patient’s beliefs to the disease and antiretroviral treatment (p <0.001) improved significantly with the pharmaceutical intervention. The more frequent pharmaceutical intervention was education to the patient to increment the adherence to the treatment (46%). Conclusion: These results demonstrate that the pharmacists’ intervention through pharmacotherapeutic follow-up improves the adherence to the antiretroviral treatment. The pharmacist was able to improve aspects of compliance and patient’s beliefs about the treatment and disease. The pharmacist could utilize CEAT-VIH as an instrument to evaluate the adherence in HIV/AIDS patients (AU)

Concordancia entre ecocardiografía prenatal y posnatal en pacientes con cardiopatías congénitas: Hospital de Niños Dorctor, Roberto Del Río / Concordance between prenatal and posnatal echocardiography in patients with congenital heart defect

Antecedentes: En Chile las malformaciones congénitas son la primera causa de mortalidad neonatal precoz, siendo las cardiopatías congénitas su principal factor. La incorporación de la ecocardiografía prenatal es de gran ayuda en su pesquisa precoz. Objetivos: Evaluar la ecocardiografía prenatal como prueba diagnóstica y su concordancia con la ecocardiografía posnatal. Métodos: Se analizaron embarazadas derivadas al Hospital de Niños Dr. Roberto del Río entre abril 2004 y abril 2008, por sospecha de cardiopatías congénitas con posterior control neonatal. Resultados: Se evaluaron 188 embarazadas tanto con diagnóstico de cardiopatía congénita como con ecocardiografía normal. La edad gestacional promedio de derivación fue de 32 semanas, siendo la principal causa la sospecha de cardiopatía congénita en el examen obstétrico de rutina. Como prueba diagnóstica se obtuvo una sensibilidad de 100 por ciento y especificidad de 40 por ciento con una moderada concordancia entre ésta y el examen postnatal. Como prueba diagnóstica la ecocardiografía prenatal, se obtuvo una sensibilidad de 100 por ciento y especificidad de 89 por ciento del examen, al ser evaluada como cardiopatías en general, con una muy buena concordancia entre ésta y el examen postnatal. Discusión: Existe una tardía derivación y diagnóstico prenatal de las cardiopatías congénitas a nivel nacional, siendo importante capacitar aún más a los obstetras que realizan este tamizaje. La ecocardiografía prenatal realizada en nuestro centro por cardiólogos es una confiable herramienta diagnóstica con una muy buena concordancia con la ecocardiografía posnatal.

Background: In Chile, congenital malformations are the first cause of early neonatal mortality, the congenital heart defects its the main factor. The incorporation of antenatal echocardiography is very helpful in your research early. Objectives: To evalúate prenatal echocardiography as a diagnosis test and their concordance with postnatal echocardiography. Methods: We analyzed pregnancy who were derived to the Hospital de Niños Dr. Roberto del Rio, between April 2004 and April 2008, where studied because suspicion of having congenital heart defects with subsequent neonatal control. Results: 188 pregnancy were evaluated either with a diagnosis of congenital heart defect or with normal echocardiography. The mean gestational age of derivation was 32 weeks, the main causes the suspicion of congenital heart defect on routine obstetric examination. When being studied as diagnosis test it was obtained a sensitivity of 100 percent and a specificity of 40 percent with a modérate concordance between both echocardiographies. When analyzing with the diagnosis test prenatal echocardiography, it was obtained a sensitivity of 100 percent and a specificity of 89 percent of the review, when evaluated as general heart defect, with a very good concordance between it and the postnatal examination. Discussion: There is a late referral and prenatal diagnosis of congenital heart defect at national level, being important to train obstetricians who perform this screening. Prenatal echocardiography performed by cardiologists at our center is a reliable diagnosis tool with a very good concordance with postnatal echocardiography.

Objetivos: El objetivo de este estudio fue adaptar y validar el “Cuestionario para evaluar la adhesión al tratamientoantirretroviral” (CEAT-VIH) para su uso en el Perú, en pacientes VIH y SIDA en tratamiento antirretroviral degran actividad (TARGA).Métodos: Se evaluó la comprensión del cuestionario así como sus propiedades psicométricas en una muestra de 41pacientes con VIH y SIDA en tratamiento antirretroviral de gran actividad (TARGA) por más de tres meses. Elperiodo de estudio estuvo comprendido entre diciembre 2005 y enero 2006, el proceso de validación incluyó la aplicacióndel cuestionario el mismo día de la toma de muestra para el análisis de la carga viral y de los linfocitos TCD4.Se analizó la fi abilidad, la correlación de la puntuación con el recuento de linfocitos TCD4 y la carga viral.Resultados: Los resultados mostraron una adecuada fi abilidad (alfa = 0,706) y validez de criterio externa: respecto alrecuento de linfocitos TCD4 (r = 0,439, p < 0,005), y respecto a la carga viral (r = - 0,548, p < 0, 005).Conclusiones: El CEAT-VIH ha demostrado ser una adecuada herramienta para evaluar el nivel de adherencia eidentifi car los factores que infl uyen en la adherencia al tratamiento antirretroviral en una muestra de pacientesVIH y SIDA en Perú

Objective: To adapt and validate the “Assessment of Adherence to Antiretroviral Therapy Questionnary” “Cuestionariopara evaluar la adhesión al tratamiento antirretroviral” (CEAT-VIH) for use in Peru, in HIV-infected patients in highlyactive antiretroviral therapy (HAART).Method: Understanding of the questionnaire was evaluated as well as its psychometric properties in 41 HIV-infectedpatients; antiretroviral therapy for at least 3 months was required. Data was obtained between December 2005 andJanuary 2006. CEAT-VIH was carried out the day when sample for HIV viral load and CD4 cell count were taken.Reliability and validity related to two external criterions were evaluated.Results: CEAT-VIH showed appropriate reliability (alpha = 0,706) and adequate external criterion-related validity for CD4cell count (r = 0,439, p < 0.005), and for HIV viral load (r = - 0,548, p < 0, 005).Conclusions: CEAT-VIH has proved to be useful to assess the level of adherence and to identify the factors affectingpatient adherence to highly active antiretroviral therapy in Peru

Astroblastoma. Case report, review of the literature, and analysis of treatment strategies.

Astroblastoma, a unique glial tumor, has been described in the literature in case reports and small series. Its rarity has prevented evidenced-based treatment stratification. An 8-year-old boy presented with signs and symptoms of raised intracranial pressure. Imaging studies of the brain demonstrated a large heterogeneously enhancing solid mass in the left frontal lobe with punctate calcifications and cystic components that created subfalcine and uncal herniation. After tumor resection, histological diagnosis revealed a high-grade cerebral astroblastoma. The child's postoperative recovery was complicated by hydrocephalus that necessitated placement of a ventriculoperitoneal shunt. Fifty-four months after undergoing gross total resection and adjuvant radiation therapy, the patient, now 12-years-old, remains tumor free and neurologically stable. Chemotherapy was reserved in the event of tumor recurrence. Since the first description of astroblastoma, its histopathological and clinical features have been debated. We review the histology, immunohistochemistry, and cytogenetics of astroblastoma as well as examine the current literature and treatment strategies for the management of both low and high-grade tumors. Continued clinical studies and longer patient follow-up with a tumor based registry would further clarify optimal treatment for this rare tumor.

An environmental pseudopotential approach to molecular interactions: Implementation in MOLPRO.

We present the implementation into the MOLPRO package of a model for the interaction of a central system with its surrounding environment. The properties of a target system enclosed by a noncovalently bound environment or solvent are modeled as those of a system embedded into the effective pseudopotential arising from the exact electrostatic Coulomb potential and the approximated exchange-repulsion potential. For the latter we use the charge-density overlap model, which relates the exchange-repulsion interaction energy between two species with the overlap of their ground-state electron charge densities. The solutions of the modified Hartree-Fock equations for the target system are obtained self-consistently. This way the exchange-induction effects arising from the converged electron-charge density of the embedded system are implicitly included. Inclusion of the correlation effects is provided by the use of post-Hartree-Fock and density-functional techniques available in the MOLPRO package. The computational and conceptual advantages provided by this approach are shown in the calculation of the dipole polarizabilities of halide and chalcogenide anions in different environments.

Determination of the profile of fatty acids of 4 species of Shigella spp by chromatography of gases.

Shigella boydii, Shigella flexneri, Shigella dysenteriae and Shigella sonnei were identified using gas chromatography instead of the traditional techniques. Their acid methyl esters profiles were determined using a gas chromatograph Hewlett Packard 5890A and a RSL-150 heliflex capillary column. A total of 192 samples were analyzed both reference strains (ATCC 8700, INDRE B2188, B2194 and B2199) and environmental isolates. 12 fatty acids were included in the profiles from which 3-hydroxytetradecanoic acid (peak 12), trans 9-octadecanoic acid (peak 22), heptadecanoic acid (peak 18) and octadecanoic acid (peak 23), were the most important for the differentiation of the species analyzed.
