ABSTRACT
Avocado demand has increased in recent years due to the nutraceutical properties that this fruit has and its positive impacts on human health; however, avocado production also requires sustainable alternatives to improve its cultivation. The objective of this study was to carry out characterization of the mineral content and phytochemical compounds in avocado fruit of the Hass variety grown using sustainable agricultural practices in Ecuador. Our results show an increase in fruit quality traits, such as firmness, and in the content of soluble solids, protein, fiber, fat, carotenoids, Ca, Mg, Zn and stearic acid in the pulp of the avocado Hass variety, as well as an initial trend of yield increase with the application of sustainable practices. Moreover, antioxidant activity was associated with polyphenol content. There were positive correlations of Mg with K and Ca, and of flavonoids with linolelaidic, linoleic and linolenic acids. Overall, our results indicate that avocado can be used as a functional and nutritional food due to its phytochemical composition and the mineral content of its pulp, which contributes to the promotion of its consumption and encourages healthy eating. In addition, the use of sustainable practices, such as fertigation and the application of microorganisms, is also promoted for growing avocado.
ABSTRACT
Resumen Los schwannomas son tumores usualmente benignos, de crecimiento lento y generalmente propios de adultos. Son muy raros en la población pediátrica y su diagnóstico requiere un alto índice de sospecha clínica. Se presenta el caso de un paciente de sexo masculino de 9 años con historia de una masa cervical asintomática, sin otros antecedentes clínicos relevantes. La escisión total de la masa fue posible e histopatología confirmó el diagnóstico de schwannoma. El paciente se recuperó completamente, con excelente pronóstico. Es necesario tener presente a los schwannomas en el diagnóstico diferencial en casos de masas cervicales en pacientes pediátricos.
Abstract Schwannomas are usually benign, slow-growing tumors, usually found in adults. They are very rare in the pediatric population and their diagnosis requires a high index of clinical suspicion. We present the case of a 9-year-old male patient with a history of an asymptomatic cervical mass, with no other relevant clinical history. Total excision of the mass was possible, and histopathology confirmed the diagnosis of schwannoma. The patient recovered completely, with excellent prognosis. It is necessary to keep in mind schwannomas in the differential diagnosis in cases of cervical masses in pediatric patients.
ABSTRACT
Introducción. Las demencias rápidamente progresivas son un grupo poco frecuente de enfermedades caracterizadas por un deterioro cognitivo y otras alteraciones neurológicas que evolucionan en el transcurso de semanas a meses. Su etiología es diversa e incluye un gran número de condiciones neurodegenerativas, tóxicas, metabólicas, autoinmunes, infecciosas y vasculares. Caso clínico. Varón de 69 años, que ingresó por demencia rápidamente progresiva y parkinsonismo causado por múltiples fístulas arteriovenosas durales tratadas exitosamente mediante terapia endovascular. Conclusión. Las fístulas arteriovenosas durales son conexiones anómalas entre las arterias durales y los senos venosos o venas corticales que constituyen una causa inusual de demencia rápidamente progresiva, pero que debe considerarse, dada la disponibilidad de un tratamiento específico con reversión de los síntomas (AU)
Introduction. Rapidly progressive dementias are an infrequent group of diseases characterised by cognitive deterioration and other neurological disorders that develop over a period ranging from weeks to months. Their causation is varied and includes a large number of neurodegenerative, toxic, metabolic, autoimmune, infectious and vascular conditions. Case report. We report the case of a 69-year-old male who was admitted to hospital due to a rapidly progressive dementia and parkinsonism caused by multiple dural arteriovenous fistulas, which were successfully treated by means of endovascular therapy. Conclusion. Dural arteriovenous fistulas are anomalous connections between the dural arteries and the venous sinuses or cortical veins that are an unusual cause of rapidly progressive dementia. They must, however, be taken into account, given the availability of a specific treatment with reversal of the symptoms (AU)
