RESUMO
Here, we report a case of direct zoonotic transmission of giardiasis between a pet chinchilla and a human. Microscopic and molecular examinations of stool samples from a child and samples of chinchilla droppings revealed cysts/DNA of Giardia intestinalis. The transmission from the chinchilla to the child has been confirmed as coprophagous after the 1-year-old toddler ingested pet chinchilla droppings. Molecular analysis of the gdh gene from both hosts classified the G. intestinalis cysts into the assemblage B genetic group, which has been previously shown to be characteristic of both human and chinchilla giardiasis. Both Giardia sub-assemblages BIII and BIV were present in the chinchilla droppings, whereas only the sub-assemblage BIV was isolated from the child's stool sample. To the best of our knowledge, this is the first report of a true zoonotic transmission of giardiasis, supporting the zoonotic potential of assemblage B.

BACKGROUND: Recognizing ictal semiology is an essential component to localization of seizure onset, especially in intractable epilepsy where surgical therapies may be beneficial. Ictal speech can be a common component of seizure semiology, but the various forms of ictal speech may have different lateralizing and localizing value. Coprolalia is a very rare form of ictal speech. METHODS: We present a 15 year old with medically intractable seizures characterized by agitation and coprolalia. RESULTS: The patient underwent surgical evaluation including video EEG, MRI, and functional neuroimaging. These studies indicated onset within the dominant frontal lobe which was further localized using stereo-electroencephalography prior to focal cortical resection. CONCLUSIONS: Ictal coprolalia is a rare presentation of ictal speech. We review the various forms of ictal speech and their value in localizing seizure onset.

Changes in eating and weight are not uncommon in dementia although they have yet to be systematically studied. These changes are of clinical importance since they can seriously affect patients' physical health and they are often a major problem for carers. These changes are also of theoretical interest since certain abnormalities may be a direct expression of specific brain pathology. Studying these changes in eating and weight may therefore further our understanding of certain of the pathological processes underlying dementia and suggest new approaches to the management of these problems.
