Rapid On-Site Evaluation by Endosonographer of Endoscopic Ultrasound Fine-Needle Aspiration of Solid Pancreatic Lesions: A Randomized Controlled Trial.

Objectives: Rapid on-site evaluation (ROSE) by cytopathologists during endoscopic ultrasound-fine-needle aspiration (EUS-FNA) of solid pancreatic lesions (SPLs) improves adequacy and diagnostic accuracy while reducing the number of needle passes. We evaluated the usefulness of ROSE performed by the endosonographer.

Methods: Patients with an SPL were randomly assigned to EUS-FNA with ROSE or non-ROSE.

DNA detection of JC and BK virus in archival urine cytospin slides.

To identify decoy cells, cytological examination was performed in urine cytospin slides. Decoy cells are related to Polyomaviruses (JC virus [JCV] and BK virus [BKV]), which are recognized worldwide due to potential infection and morbidity in kidney transplant recipients. Cytologically, it is difficult to evaluate the cytopathic effect of JCV and BKV in urine of patients with urothelial neoplasia.

Sentinel Lymph Node Navigation Surgery for Early Gastric Cancer: Is It a Safe Procedure in Countries with Non-Endemic Gastric Cancer Levels? A Preliminary Experience.

Purpose: Early diagnosis of gastric cancer is still the exception in Western countries. In the East, as in Japan and Korea, this disease is an endemic disorder. More conservative surgical procedures are frequently performed in early gastric cancer cases in these countries where sentinel lymph node navigation surgery is becoming a safe option for some patients.

Lymph node metastasis in early gastric cancer.

Objective: to evaluate the incidence of lymph node metastasis in early gastric cancer, identifying risk factors for its development.

Methods: we conducted a prospective study of patients with gastric cancer admitted to the Section of the Esophago-Gastric Surgery of the Surgery of Service HUCFF-UFRJ, from January 2006 to May 2012.

Results: the rate of early gastric cancer was 16.

Minor gastric resections with modified lymphadenectomy in early gastric cancer with negative sentinel node.

Objective: To study the sentinel lymph node in early gastric cancer as a diagnostic method of unsuspected lymph node metastasis, which may allow the performance, in those with negative lymph nodes, of smaller gastric resections with limited lymphadenectomy.

Methods: We studied seven patients with early gastric cancer treated at the Hospital Universitário Clementino Fraga Filho, Federal University of Rio de Janeiro, from September 2008 to May 2011, who underwent sentinel lymph node exams, performed by intraoperative peritumoral endoscopic injection of patent blue dye.

Results: We found an average of three sentinel nodes per patient.
