Yellow fever vaccine-associated adverse events following extensive immunization in Argentina.

As a consequence of YF outbreaks that hit Brazil, Argentina, and Paraguay in 2008-2009, a significant demand for YF vaccination was subsequently observed in Argentina, a country where the usual vaccine recommendations are restricted to provinces that border Brazil, Paraguay, and Bolivia. The goal of this paper is to describe the adverse events following immunization (AEFI) against YF in Argentina during the outbreak in the northeastern province of Misiones, which occurred from January 2008 to January 2009. During this time, a total of nine cases were reported, almost two million doses of vaccine were administered, and a total of 165 AEFI were reported from different provinces.

Validation of a new scale for the evaluation of sialorrhea in patients with Parkinson's disease.

Sialorrhea is common in Parkinson disease (PD), affecting approximately 70% to 75% of patients. Several tools for measuring saliva volume or production exist, but none are designed specifically for assessing sialorrhea-related discomfort. The objective of this study was to develop and validate a clinical scale for subjective evaluation of sialorrhea in PD.

Accuracy of acute levodopa challenge for clinical prediction of sustained long-term levodopa response as a major criterion for idiopathic Parkinson's disease diagnosis.

Clinical idiopathic Parkinson's disease (PD) diagnosis requires following strict clinical criteria. Final definitive diagnosis can only be made after pathological confirmation and, despite following clinical criteria, several cases are misdiagnosed. We assessed sensitivity and specificity of acute challenge with levodopa (L-dopa) to predict sustained long-term L-dopa responsiveness as a major criterion for clinical diagnosis of PD.
