Prevalence of parkinsonism and Parkinson's disease in the Arosa Island (Spain): a community-based door-to-door survey.

There are scarce epidemiological data on parkinsonism in Spain. Since the Arosa Island community (Northwestern Spain) has been for centuries relatively isolated, it represents a potentially useful setting to undercover genetic factors with a founder effect, as well as local environmental influences. We performed a one-stage door-to-door survey in the Arosa Island in 2004 to determine the prevalence of parkinsonism and Parkinson's disease (PD) in the population aged 65 years or over.

Treatment completion in latent tuberculosis infection at specialist tuberculosis units in Spain.

Setting: Treatment of latent tuberculosis infection (LTBI) is essential for tuberculosis (TB) control in low-prevalence countries. However, the long treatment duration and adverse events frequently result in suboptimal treatment completion.

Objective: To determine completion rates of LTBI treatment and to identify risk factors for non-completion of treatment.

The global impact of endoscopic ultrasound (EUS) regarding the survival of a pancreatic adenocarcinoma in a tertiary hospital.

Background: Pancreatic ductal adenocarcinoma is a type of neoplasm with a high mortality rate. There are a number of different procedures that may be followed in the study of the pancreas; one such procedure is endoscopic ultrasonography (EUS).

Objective: This study aimed to retrospectively evaluate the impact on patient survival of a biliopancreatic EUS performed 2 months prior to the first treatment session of the pancreatic ductal adenocarcinoma.

Types of pancreatic cancer in EUS-FNA and chemotherapy.

To determine the variety of chemotherapy drugs administrable for malignant pancreatic neoplasm as a result of typification with endoscopic ultrasonography-fine needle aspiration (EUS-FNA). A retrospective assessment, in one center, over a period of 1 year. Only malignant pancreatic neoplasm diagnosed by EUS-FNA was recorded.

[A case-control study of the influence of the smoking behaviour in multiple sclerosis].

Introduction: Several epidemiological studies have demonstrated that there is a genetic factor of susceptibility in Multiple Sclerosis (MS) and that the environmental factors play an important important role in their development. Smoking is among the environment factors studied. In fact, several studies have established a relationship between smoking and multiple sclerosis, although most of them did not find significant results or found that these were contradictory.
