RESUMO
RESUMEN Introducción: El síndrome de Guillain-Barré (SGB) es la principal causa de parálisis en niños, y la variante faringo-cérvico-braquial (FCB) es poco común. Esta variante atípica se asocia con secuelas y requiere rehabilitación prolongada. Dado el enfoque predominante durante el tratamiento agudo, este estudio describe la evolución motora, respiratoria y funcional de un niño con SGB, variante FCB, en un centro de neurorrehabilitación durante el período subagudo. Presentación del caso: Un niño de 11 años ingresó con cuadriparesia fláccida y un mayor compromiso en los miembros superiores (MMSS), traqueotomizado y dependiente para las actividades de la vida diaria. Recibió un programa de evaluación y abordaje interdisciplinario intensivo. Logró la decanulación, la marcha y la independencia funcional con adaptaciones, y fue dado de alta luego de 16 semanas. Conclusión: La evolución del caso concuerda con lo reportado en la literatura sobre la presencia de secuelas y los tiempos prolongados de recuperación de la variante FCB. El niño recibió rehabilitación interdisciplinaria intensiva durante 16 semanas y, aún luego de un año, continuaba presentando debilidad a nivel distal de los MMSS y fatiga. Estos hallazgos resaltan la importancia de una intervención temprana y una rehabilitación integral en pacientes pediátricos con esta variante particular del SGB.
ABSTRACT Introduction: The Guillain-Barré syndrome (GBS) is the primary cause of paralysis in children, with the pharyngeal-cervical-brachial (PCB) variant being rare. This atypical form is associated with sequelae and requires prolonged rehabilitation. Given the predominant focus during acute treatment, this study describes the motor, respiratory, and functional clinical course of a child with GBS, PCB variant, in a neurorehabilitation center during the subacute period. Case presentation: An 11-year-old boy was admitted with flaccid quadriparesis and greater involvement of the upper limb (UL), tracheotomized, and dependent for activities of daily living. He underwent an intensive interdisciplinary evaluation and treatment program. The patient achieved decannulation, gait, and functional independence with adaptations, and was discharged after 16 weeks. Conclusion: The clinical course of the case aligns with the literature regarding the presence of sequelae and prolonged recovery times of the PCB variant. The child underwent intensive interdisciplinary rehabilitation for 16 weeks and, even after one year, continued to experience weakness in the distal UL and fatigue. These findings highlight the importance of early intervention and comprehensive rehabilitation in pediatric patients with this particular variant of GBS.
RESUMO
The aim of this study is to examine the relationship between body mass index (BMI) and intelligence quotient scores (IQ). The sample included 11 patients with pediatric multiple sclerosis between 8 and 17 years, mean age 14.45 years (SD = 2.69). The BMI was calculated as weight in kilograms divided by the square of height in meters. The Wechsler Intelligence Scale for Children V and the Abbreviated Weschler Intelligence Scale were used to measure total IQ. Average sample BMI and IQ were 24.61 (SD = 5.53) (range: 19-39.4) and 86.63 (SD = 14.79) (range: 66-111), respectively. Results of the Pearson correlation indicated that there was a significant negative association between BMI and IQ, (r = -0.608, p = 0.042). R-squared was 0.370. We discuss if lower IQ lead to BMI gains or whether overweight/obesity lead to intellectual functioning changes. Implication for practice and future research are presented.

An on-line scandium preconcentration and determination system implemented with inductively coupled plasma optical emission spectrometry associated with flow injection was studied. Trace amounts of scandium were preconcentrated by sorption on a minicolumn packed with oxidized multiwalled carbon nanotubes, at pH 1.5. The retained analyte was removed from the minicolumn with 30% (v/v) nitric acid. A total enrichment factor of 225-fold was obtained within a preconcentration time of 300 s (for a 25 mL sample volume). The overall time required for preconcentration and elution of 25 mL of sample was about 6 min; the throughput was about 10 samples per hour. The value of the detection limit was 4 ng L(-1) and the precision for 10 replicate determinations at 100 ng L(-1) Sc level was 5% relative standard deviation, calculated from the peak heights obtained. The calibration graph using the preconcentration system was linear with a correlation coefficient of 0.9996 at levels near the detection limits up to at least 10 mg L(-1). After optimization, the method was successfully applied to the determination of Sc in an acid drainage from an abandoned mine located in the province of San Luis, Argentina.
