ABSTRACT
ABSTRACT Background: A treatment-related fluctuation (TRF) in a patient with Guillain-Barré syndrome (GBS) is defined as clinical deterioration within two months of symptom onset following previous stabilization or improvements with treatment. Objective: To investigate the clinical characteristics and factors that could increase the risk of relapse of GBS in patients with and without TRFs. Methods: Retrospective review of medical records of patients (>18 years) with GBS evaluated between January/2006 and July/2019. Demographic and clinical characteristics, ancillary studies, treatment received, and the clinical course of patients with and without TRFs were analyzed. Results: Overall, 124 cases of GBS were included; seven (5.6%) presented TRFs. GBS-TRF cases were triggered more frequently by infectious mononucleosis (28.57 vs. 8.55%; p=0.01). GBS-TRF were initially treated with plasmapheresis more frequently than those without TRF (14.29 vs. 1.70%; p=0.0349). Combined treatment (71.43 vs. 4.27%; p<0.001) and corticosteroids (42.86 vs. 1.71%; p<0.001) were more commonly used in the GBS-TRF group. GBS-TRF patients presented a higher median initial disability score (4 vs. 2; p=0.01). Conclusions: Patients with GBS triggered by infectious mononucleosis and a high degree of initial disability have higher chances of developing TRFs. Although patients with TRF were treated with plasmapheresis more often, the total number was too low to suggest a link between plasma exchange and TRF.
RESUMEN Antecedentes: Una fluctuación relacionada al tratamiento (FRT) en un paciente con síndrome de Guillain-Barré (SGB) se define como un deterioro clínico dentro de los dos meses posteriores al inicio de los síntomas después de una estabilización previa o mejoría con el tratamiento. Objetivo: Investigar las características clínicas y los factores que podrían incrementar el riesgo de recaída, comparando pacientes con SGB, con y sin FRT. Métodos: Revisión retrospectiva de historias clínicas de pacientes (>18 años) con SGB evaluados entre enero/2006 y julio/2019. Se analizaron las características demográficas y clínicas, los estudios complementarios, el tratamiento recibido y la evolución clínica de los pacientes con y sin FRT. Resultados: Se incluyeron 124 casos de SGB en el total; 7 (5,6%) presentaron FRT. Los casos de SGB con FRT se desencadenaron con mayor frecuencia por mononucleosis infecciosa (28,57 vs. 8,55%; p=0,01). Los casos de SGB con FRT se trataron inicialmente con plasmaféresis con más frecuencia que aquellos sin FRT (14,29 vs. 1,70%; p=0,0349). El tratamiento combinado (71,43 vs. 4,27%; p<0,001) y los corticosteroides (42,86 vs. 1,71%; p<0,001) se utilizaron con mayor frecuencia en el grupo de SGB con FRT. Los pacientes con FRT presentaron una escala de discapacidad inicial mediana más alta (4 vs. 2; p=0,01). Conclusiones: Aquellos SGB desencadenados por mononucleosis infecciosa y un alto grado de discapacidad inicial tienen una mayor probabilidad de desarrollar FRT. Aunque los pacientes con FRT fueron tratados con plasmaféresis con mayor frecuencia, el número total fue demasiado bajo para sugerir un vínculo entre la plasmaféresis y FRT.
ABSTRACT
ABSTRACT Objective: Tyrosinemia type III (HT III) is the rarest form of tyrosinemia, and the full clinical spectrum of this disorder is still unknown. The neurological involvement varies, including intellectual impairment and attention deficit disorder with hyperactivity (ADHD). We report the case of two siblings diagnosed with HT III at different ages. Case description: The index case was diagnosed by newborn screening for endocrine and metabolic disorders, starting a low-protein diet immediately, with a consistent decrease in tyrosine levels. By the age of three, the child displayed a hyperactive behavior, starting treatment for ADHD two years later. At seven years of age, he shows a slight improvement in terms of behavior and attention span and has a cognitive performance slightly lower than his peers, despite maintaining acceptable tyrosine levels. His sister, who had a history of ADHD since age five, was diagnosed with HT III after family screening at the age of eight. Despite initiating a dietetic treatment, her behavior did not improve, and she has a mild intellectual impairment. Comments: This is the first case report describing siblings with HT III who underwent nutritional treatment with a low-protein diet in different phases of life, with a better neurological and behavioral evaluation in the patient who started treatment earlier.
RESUMO Objetivo: A tirosinemia tipo III (TT III) é a forma mais rara das tirosinemias e o espectro clínico desta entidade não está totalmente esclarecido. O envolvimento neurológico é variável, incluindo o atraso cognitivo ou transtorno do déficit de atenção com hiperatividade (TDAH). Descrevemos o caso de dois irmãos que foram diagnosticados com TT III em idades diferentes. Descrição dos casos: O caso índice foi diagnosticado no contexto do rastreio endócrino-metabólico neonatal, tendo iniciado imediatamente dieta hipoproteica, com redução consistente dos níveis de tirosina. Por volta dos três anos, foi detectado um comportamento hiperativo, tendo iniciado dois anos depois tratamento para o TDAH. Aos sete anos, apresenta leve melhora de comportamento e da atenção e avaliação cognitiva levemente inferior ou pouco abaixo quando comparado a crianças da mesma faixa etária, apesar de manter níveis aceitáveis de tirosina. A sua irmã, com história de TDAH desde os cinco anos, foi diagnosticada de TT III aos oito anos no contexto do rastreio de familiares. Apesar de iniciar tratamento dietético, nenhum efeito foi notado em termos de comportamento e a doente apresenta leve atraso cognitivo. Comentários: Este é o primeiro caso clínico descrito de irmãos com TT III que iniciaram terapêutica dietética com dieta hipoproteica em diferentes fases da vida, com melhor avaliação em termos neurológicos e comportamentais no doente que iniciou tratamento mais precocemente.

La enfermedad de Pompe (EP) es un desorden metabólico autosómico recesivo infrecuente, producido por la ausencia o deficiencia de la enzima lisosomal alfa-glucosidasa ácida en los tejidos de los individuos afectados. Se considera enfermedad de Pompe de inicio tardío (EPIT) en aquellos individuos de más de un año de edad al comienzo de los síntomas. El objetivo del presente consenso es el de actualizar las pautas y recomendaciones para un correcto tratamiento de los pacientes con EPIT, tomando como referencia los lineamientos del Consenso Argentino para el diagnóstico, seguimiento y tratamiento de la enfermedad de Pompe publicado en el año 2013. Se organizó un consenso que reunió profesionales con experiencia en la EP en las áreas de clínica médica, diagnóstico de laboratorio, neuropatología, neumonología, nutrición, neurología, enfermedades metabólicas, enfermedades neuromusculares y rehabilitación. Se realizó una actualización de la bibliografía sobre EPIT, con especial atención en las publicaciones relevantes de los últimos cuatro años. Los términos finales del documento fueron consensuados por todo el grupo de trabajo. Cada participante proporcionó su declaración de conflicto de intereses. El resultado es una actualización del último Consenso Argentino para la EP, con particular enfoque en su forma de comienzo tardío. Tratándose de una afección infrecuente, en la que los datos disponibles son limitados, las presentes recomendaciones deben ser consideradas como opinión de expertos.
Pompe's disease (PD) is an infrequent metabolic autosomic recessive disorder produced by the lack or deficiency of the acid alpha-glucosidase lysosomal enzyme in tissues of involved individuals. Delayed-onset PD is considered whenever symptoms onset start after one year of age. We present an update of the recommendations for the management of delayed-onset PD, taking as reference the guidelines from the Argentine Consensus for diagnosis, treatment and follow-up of PD published in 2013. The present consensus gathered several experts in PD in the areas of internal medicine, laboratory diagnosis, neuropathology, pulmonology, nutrition, neurology, metabolic and neuromuscular disorders as well as rehabilitation to perform an update of the literature of delayed-onset PD, with special attention on relevant information published within the last 4 years. The entire working group approved the final version of the consensus. Each participant provided a declaration of conflict of interest. As a result, it is an update of the previous Argentine PD Consensus with focus on the delayed-onset presentation of the disease. Being such infrequent disorder, available data were rather limited and thus, the recommendations represent expert opinions.

A case is reported in which an abdominal protrusion appeared in relation with a zosteric eruption at 11th dorsal dermatome. The motor deficit in zoster is unusual (2-3 percento in the reported series) and generally recognized when the extremities are affected. The frequency with which the abdominal muscles are involved is estimated to be around 0.17 percento, according to a clinical series. The aim of this report is to draw attention to the abdominal wall paresis that can result when zoster involves the caudal dorsal dermatomyotomes. This in turn, leads to abdominal distension which needs to be differentiated from other causes.
