[Infection of wild rats with Angiostrongylus costaricensis by intraperitoneal subcutaneous route].

Three groups of cotton rats (Sigmodon hispidus) were infected with Angiostrongylus costaricensis; the first was inoculated by stomach tube; the second intraperitoneally and the third subcutaneously. In all the groups each rat received 50 L3. The highest rates of infection (51.5%) were obtained by the intraperitoneal route, followed by oral inoculation (47.1%). Poor results were observed (10.5%) subcutaneously.

[Equilibrium disorders in childhood].

Dizziness and imbalance are uncommon in children, but often alarming for their families. A detailed interview and otoneurological examination are important for reaching a specific diagnosis and treatment. The purpose of our study was to obtain our own etiological, clinical and diagnostic statistics, and to review the major related pathologies. We report a series of 76 children with imbalance or dizziness as the presenting symptom. Paroxysmal benign vertigo of childhood was the most common pathology in our study, followed by vestibular neuronitis. Our findings were compared to those of other authors. Early diagnosis is emphasized as the most important factor for achieving an effective vestibular rehabilitation in children.
