Human toxocariasis is a zoonotic parasitic disease that represents extensive morbidity in many countries. Caused by Toxocara canis and Toxocara cati, the clinical spectrum of this helminthiasis can be extended from asymptomatic forms up to life-threatening syndromes, such as the visceral larva migrans. Its epidemiology and burden is not clear; many times it is not diagnosed and, in most countries, it is not a notifiable disease. Some recent reviews have shown a large range of variability in terms of reported seroprevalence by countries. In this review, we summarized information regarding human toxocariasis burden of disease and control efforts in the region of the Americas.
Cutaneous manifestations of arthropod-borne infections are varied and nonspecific. Their atypical presentations are mainly related to immune impairment and strain virulence. When considering a patient with skin lesions, other clinical and laboratory features must be taken into account in order to make an accurate diagnostic approach.
El sistema nervioso central es uno de los focos extrapulmonares afectados con mayor frecuencia por tuberculosis, no obstante, el tuberculoma epidural espinal es considerado una rareza. Se presenta el caso de un paciente de cuatro años de edad, quien consulta por cuadro de cuadriparesia progresiva. Al examen de líquido cefalorraquídeo se evidenció disociación proteínico celular diagnosticándose síndrome de Guillain Barré, sin embargo, tras la aparición de signos meníngeos, se realizó una resonancia nuclear magnética de columna en la que se evidenció lesión compresiva a nivel cervicodorsal que fue posteriormente explorada quirúrgicamente por neurocirugía, encontrándose una lesión epidural cuyo estudio microbiológico, cultivo y estudio de reacción en cadena de la polimerasa se reportaron positivos para Mycobacterium tuberculosis, por lo que se inició tratamiento antituberculoso observándose mejoría clínica y progresiva con recuperación de la marcha tras el procedimiento quirúrgico.
