ABSTRACT
El síndrome de Tolosa Hunt es un cuadro inflamatorio del seno cavernoso, idiopático y caracterizado por uno o más episodios de dolor orbital unilateral asociado o seguido de paresia oculomotora (afección del III, IV y VI nervio craneal) y en ocasiones con compromiso de la rama maxilar del nervio trigémino. Nosotros presentamos un hombre de 27 años con episodios de oftalmoparesia dolorosa derecha concomitantes a cuadros de rinosinusitis agudas. Su estudio fue negativo y en una de sus recurrencias se encontró en la RM de alta resolución de senos cavernosos, compromiso inflamatorio con captación de gadolinio de los nervios III, IV, V2 y VI derechos. Dado los hallazgos, se planteó el diagnóstico de STH exacerbado por la rinosinusitis e inició tratamiento corticoidal prolongado.
Tolosa Hunt Syndrome is the idiopathic inflammation of cavernous sinus, characterized by one or more episodes of unilateral orbital pain followed by ophtalmoparesis (III, IV o VI nerve palsy) and sometimes the affection of maxillary branch of the trigeminal nerve. We describe the case of a 27 years old man with episodes of painful right ophtalmoparesis associated with acute rhinosinusitis. On high resolution MRI there was inflammation of the III, IV, V2 and VI right nerves with gadolinium enhancement. We propose the THS diagnosis exacerbated by rhinosinusitis and started on chronic steroid therapy.

This study dissected 42 cadavers to investigate the level of the iliocava junction and the relationship with the lumbosacral spine and the aortic bifurcation. The iliocava junction was between L4 and S1, most often at the level of L5 (64%) and on the median third of the spine (55%). The average height of the iliocava junction was 15.5 mm. The mean interiliac angle was 69 degrees . It was not related to the width of the iliocava junction. The iliocava junction covered the whole of the L5-S1 disc in 12% of cases. The iliocava junction was located above the aortic bifurcation only in 1 case. The mean distance between iliocava junction and aortic bifurcation was 19 mm. The variability of the iliocava confluence is high and complicates the anterior approach to the lumbosacral spine.

The Biozzi "high" (BH) and "low" (BL) responder mice (Selection III) differed in their susceptibility to Trypanosoma cruzi. The BH strain responded quickly to the infection, similar to the reaction of (CBA X C57B1/10)F1 mice but in contrast to the susceptible BL strain. We suggest that the IgG response mounted by the host during the prepatent period of the infection is crucial to the outcome of the infection.
