ABSTRACT
The isolated unilateral palsy of the hypoglossal nerve is an unusual sign in daily medical practice. We present the case of a 74 year old man, without relevant medical history, who started with headache and difficulty to swallow. On the physical examination, he had isolated hypoglossal nerve palsy without evidence of tongue atrophy or fasciculation. The patient had a good spontaneous evolution. Idiopathic isolated hypoglossal nerve palsy requires an exhaustive evaluation with neuroimages and complementary exams. It usually presents partial or total spontaneous remission.

La parálisis aislada del nervio hipogloso es un signo infrecuentemente observado en la práctica neurológica diaria. Se presenta el caso de un hombre de 74 años, sin antecedentes clínicos de importancia, que consultó por comenzar en forma aguda con dolor retroauricular y dificultad en la deglución. En el examen neurológico se constató paresia del nervio hipogloso izquierdo como único dato positivo, sin evidencia de atrofia o fasciculaciones. Los estudios de neuroimágenes no mostraron hallazgos patológicos. El paciente evolucionó favorablemente en forma espontánea. La parálisis aislada e idiopática del nervio hipogloso requiere una exhaustiva evaluación con neuroimágenes y exámenes complementarios. Habitualmente presenta remisión parcial o total espontánea.

ABSTRACT
The in vitro germination of 11 Metarhizium anisopliae and 11 Beauveria bassiana isolates originating from substrates collected in rural peridomestic areas in Central Brazil where triatomines are common was tested. Conidia completed germination up to 24 h after exposure to water activity of > 0.99 aw in all isolates tested. At lower 0.93 aw germination was delayed but conidia of most isolates germinated at high rates (> 98%) within 216 h of incubation. Activities of 2 M. anisopliae and 2 B. bassiana isolates with different patterns of germination at 0.93 aw were tested in Triatoma infestans third instar nymphs. There was no relationship between germination kinetics in vitro at 0.93 aw and their activity in vivo at 98, 75 and 43% relative humidity (rh). Isolates with accelerated germination at 0.93 aw were not more virulent at 75 and 43% rh compared with isolates with retarded or no germination. Highest mortalities were observed at 98% rh, and they did not exceed 25% after 25 d incubation at lower 75 and 43% rh. Isolates that originated from a region with an extensive annual arid period showed no adaptation to lower humidity in their activity against T. infestans.
