Background. Prognosis of PD is variable. Most studies show higher mortality rates in PD patients compared to the general population. Clinical and epidemiologic factors predicting mortality are poorly understood. Methods. Clinical and epidemiologic features including patient history and physical, functional, and cognitive scores were collected from a hospital-based cohort of PD patients using standardized protocols and clinical scales. Data on comorbidities and mortality were collected on follow-up. Results. During a mean follow-up of 4.71 years (range 1–10), 43 (20.9%) of the 206 patients died. Those who died had higher mean age at disease onset than those still alive at the last follow-up (67.7 years versus 56.3 years; p<0.01). In the univariate analysis, age at baseline was associated with decreased survival. In the adjusted Cox proportional hazards model, age at disease onset and race/ethnicity were predictors of mortality. Conclusions. Late age at disease onset and advanced chronological age are associated with decreased survival. Comorbidities and PD characteristics were not associated with decreased survival in our sample. Race/ethnicity was found in our study to be associated with increased hazard of mortality. Our findings indicate the importance of studying survival among different populations of PD patients.

An essay is presented on the role of the state and the judiciary on the national policy on pharmaceuticals in Brazil. It states that the Brazilian Unified Health System (UHS) established the right to health and put the obligation on the state to provide health care while the courts assist in guaranteeing patients' right to health. It offers the UHS recommended policies including policy implementation, monitoring and control on the delivery of medicines, and securing the right to health.

There is a lack of evidence on the clinical efficacy and safety of the recently released Chinese botulinum toxin serotype A (Prosigne) for the treatment of focal dystonias and hemifacial spasm. Determining a more precise role of Prosigne in the treatment of such conditions is of paramount importance, because botulinum toxin type A treatments have a huge economic implication in health services, especially in developing countries. The aim of our study was to compare the efficacy and safety of Prosigne in the treatment of blepharospasm and hemifacial spasm in comparison to Botox. We performed a double-blind, randomized, crossover study enrolling 26 patients. There were no significant differences between Prosigne and Botox regarding subjective global improvement, response onset, efficacy duration, and incidence and severity of adverse events. Our results suggest that Prosigne and Botox are comparable with respect to efficacy and safety for the short-term treatment of blepharospasm and hemifacial spasm.
