Achalasia of the cardia is associated with an increased risk of esophageal carcinoma. The real burden of achalasia at the malignancy genesis is still a controversial issue. Therefore, there are no generally accepted recommendations on follow-up evaluation for achalasia patients. This study aims to estimate the risk of esophageal adenocarcinoma and squamous(More)
BACKGROUND Autoantibodies to ribosomal P proteins (anti-rib P) are specific serological markers for systemic lupus erythematosus (SLE) and are associated with liver involvement in this disease. The similarity in autoimmune background between autoimmune hepatitis (AIH) and SLE-associated hepatitis raises the possibility that anti-rib P antibodies might also(More)
BACKGROUND: Most prevalent esophageal neoplasm is squamous cell carcinoma and adenocarcinoma. Other tumors are uncommon and poorly studied. Primary neuroendocrine esophageal neoplasm is a rare carcinoma and most of its therapy management is based on lung neuroendocrine studies. Neuroendocrine tumors can be clustered in the following subtypes: high grade(More)
BACKGROUND Esophageal cancer is one of the leading causes of mortality among the neoplasms that affect the gastrointestinal tract. There are several factors that contribute for development of an epidemiological esophageal cancer profile in a population. OBJECTIVE This study aims to describe both clinically and epidemiologically the population of patients(More)
BACKGROUND Carpal tunnel syndrome (CTS) is the most common compression neuropathy of the upper limb. Close to 5% of patients with chronic renal failure who need hemodialysis present CTS. Clinical history and physical examination remain the most adequate tools for diagnosis, and there is still controversy regarding the most reliable test to complement it.(More)
BACKGROUND Image distortion limits application of direct 3-T magnetic resonance imaging for stereotactic functional neurosurgery. OBJECTIVE To test the application of a method to correct and curtail image distortion of 3-T magnetic resonance images. METHODS We used a phantom head model mounted on a platform with the dimensions and features of a(More)
OBJECTIVE To evaluate the pressure perception thresholds on the pulp of two fingers (index and little fingers), among a Brazilian population with no nerve injury or neuropathy. METHODS We used the Pressure-Specified Sensory Device (a computerized device) to derive static and dynamic normal pressure perception thresholds and two-point discrimination(More)
Background: Despite recent advances in diagnosis and treatment, esophageal cancer still has high mortality. Prognostic factors associated with patient and with disease itself are multiple and poorly explored. Aim: Assess prognostic variables in esophageal cancer patients. Methods: Retrospective review of all patients with esophageal cancer in an(More)
Background: Knowing esophageal tumors behavior in relationship to lymph node involvement, distant metastases and local tumor invasion is of paramount importance for the best esophageal tumors management. Aim: To describe lymph node involvement, distant metastases, and local tumor invasion in esophageal carcinoma, according to tumor topography and(More)
Intraperitoneal free cancer cells in gastric adenocarcinoma are associated with a poor outcome. However, the true prognostic value of intraperitoneal free cancer cells is still unclear, leading to a lack of consensus in the management of gastric cancer. The aim of the present study is to perform a systematic review and meta-analysis to analyze(More)
