Management Strategy of Intracranial Complications of Sinusitis: Our Experience and Review of the Literature.

Objective: Sinusitis or rhinosinusitis is a very common disease worldwide, and in some cases, it leads to intracranial complications (ICS). These are more common in immunocompromised patients or with underlying comorbidities, but even healthy individuals, can be affected. Nowadays, ICS have become less common thanks to improved antibiotic therapies, radiological diagnostic methods, surgical techniques and skills.

[Capgras delusion and Alzheimer disease].

Capgras delusion is classified with the misidentification syndromes. In dementia it associates cognitive deficiency of memory and facial recognition (prosopoagnosia) with delirious idea of substitution by a double. The first reported case in the paper describes the important affective and comportmental reactions due to the identification of a double perceived as an imposter, affecting both the suffering person and his family.

Inhibition in early Alzheimer's disease: an fMRI-based study of effective connectivity.

Changes of functional connectivity in prodromal and early Alzheimer's disease can arise from compensatory and/or pathological processes. We hypothesized that i) there is impairment of effective inhibition associated with early Alzheimer's disease that may lead to ii) a paradoxical increase of functional connectivity. To this end we analyzed effective connectivity in 14 patients and 16 matched controls using dynamic causal modeling of functional MRI time series recorded during a visual inter-hemispheric integration task.

Neurogenic pain and abnormal movements contralateral to an anterior parietal artery stroke.

Background: Unlike delayed pain syndrome, acute central pain is a very rare symptom in acute stroke. In addition, the incidence of hemiballismus in acute cerebrovascular diseases is less than 1%. To our knowledge, the association of these 2 clinical conditions has not been previously described.
