[Relapse of chronic inflammatory demyelinating polyneuropathy following treatment with zoledronic acid].

Background: Zoledronic acid is a nitrogen-containing bisphosphonate that is frequently used in the treatment of osteoporosis. Many patients experience a so-called acute-phase reaction during initial treatment; this is characterized by flu-like symptoms and fever.

Case Description: We describe a 61-year-old woman who suffered from chronic inflammatory demyelinating polyneuropathy (CIDP), and who was started on intravenous zoledronic acid treatment as adjuvant therapy for breast cancer.

Dietary fatty acids and the risk of Parkinson disease: the Rotterdam study.

Background: Unsaturated fatty acids are important constituents of neuronal cell membranes and have neuroprotective, antioxidant, and anti-inflammatory properties.

Objective: To determine if a high intake of unsaturated fatty acids might be associated with a lower risk of Parkinson disease (PD).

Methods: In the Rotterdam Study, a prospective population-based cohort study of people ages > or =55, the association between intake of unsaturated fatty acids and the risk of incident PD was evaluated among 5,289 subjects who were free of dementia and parkinsonism and underwent complete dietary assessment at baseline.

Microbleeds in hereditary cerebral hemorrhage with amyloidosis-Dutch type.

In a hereditary variant of cerebral amyloid angiopathy (CAA), cerebral hemorrhage with amyloidosis-Dutch type, supratentorial microbleeds were found to occur independently of the presence of hypertension, whereas hypertension probably contributed to the development of cerebellar microbleeds. This predictable hereditary variant of CAA may be a useful model to study microbleeds in relation to CAA.
