Prevalence of Essential Tremor on Arosa Island, Spain: a Community-based, Door-to-Door Survey.

Background: The prevalence of essential tremor (ET) is still not well understood and the various studies performed to date have generated highly variable results. Few epidemiologic studies on the prevalence of ET have been reported from Spain.

Methods: A one-stage door-to-door survey was conducted on Arosa Island, northwestern Spain, to determine the prevalence of ET in the population aged 65 years and older.

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.

Evaluation of the bilio-pancreatic region using endoscopic ultrasonography in patients referred with and without abdominal pain and CA 19-9 serum level elevation.

Context: When assessing the bilio-pancreatic region, collating the findings of serum CA 19-9 values together with findings from various imaging tests--especially endoscopic ultrasonography--is not a simple issue in daily clinical practice.

Aim: To assess the usefulness of endoscopic ultrasonography in an Endoscopic Ultrasonography Unit in two situations: patients with asymptomatic elevation of serum CA 19-9 and patients who presented with abdominal pain plus elevation of CA 19-9.

Methods: A retrospective study of those patients who underwent radial endoscopic ultrasonography between October 2004 and September 2005 in our institution, considering an elevation of CA 19-9 (equal to or greater than 37 U/mL) with or without symptoms.
