RESUMO
INTRODUCCIÓN: La toxoplasmosis congénita continúa siendo un problema de salud pública. Aun cuando existen guías plenamente divulgadas y conocidas, se observa poca implementación de ellas en algunas instituciones de salud y una inadecuada interpretación de las pruebas serológicas en las gestantes. Esto puede generar falta de captación y tratamiento en embarazadas con primoinfección por Toxoplasma gondii. CASOS CLÍNICOS: Se reportan dos casos de toxoplasmosis congénita, uno de ellos con desenlace fatal. En ambos no se siguieron las guías de práctica clínica, lo cual conllevó un diagnóstico tardío y, en consecuencia, un manejo en condiciones inapropiadas con daños graves. CONCLUSIONES: La toxoplasmosis es una infección congénita aún prevalente en algunos países, con secuelas graves, discapacidad neurológica y riesgo de daño ocular, incluso tardío. Además, existen algunas variedades de cepas de T. gondii con un comportamiento más agresivo en Latinoamérica, lo cual empeora la presentación de los casos e incluye mayor riesgo de muerte. BACKGROUND: Congenital toxoplasmosis continues to be a public health problem. Although clinical guidelines have been divulgated and are well known, they are not implemented in some health institutions, in addition of an inappropriate interpretation of the serological tests in pregnant women. This situation can lead to lack of screening and treatment in pregnant women with primary Toxoplasma gondii infection. CASE REPORTS: We report two cases of congenital toxoplasmosis, one with a fatal outcome. In both cases, the clinical guidelines were not initially followed, leading to a delayed diagnosis and, consequently, an inappropriate management in conditions with severe damage. CONCLUSIONS: Toxoplasmosis is a congenital infection still prevalent in some countries, with severe sequelae, neurological disability, and even late risk of ocular damage. Additionally, some varieties of the T. gondii strains have a more aggressive pattern in Latin America, worsening the clinical presentation of cases and including a high risk of death.

RESUMO
Cocoa is an important commodity crop, not only to produce chocolate, one of the most complex products from the sensory perspective, but one that commonly grows in developing countries close to the tropics. This paper presents novel techniques applied using cover photography and a novel computer application (VitiCanopy) to assess the canopy architecture of cocoa trees in a commercial plantation in Queensland, Australia. From the cocoa trees monitored, pod samples were collected, fermented, dried, and ground to obtain the aroma profile per tree using gas chromatography. The canopy architecture data were used as inputs in an artificial neural network (ANN) algorithm, with the aroma profile, considering six main aromas, as targets. The ANN model rendered high accuracy (correlation coefficient (R) = 0.82; mean squared error (MSE) = 0.09) with no overfitting. The model was then applied to an aerial image of the whole cocoa field studied to produce canopy vigor, and aroma profile maps up to the tree-by-tree scale. The tool developed could significantly aid the canopy management practices in cocoa trees, which have a direct effect on cocoa quality.
