Transmission electron microscopy of percutaneous fine needle aspirates from lung: a study of 70 cases.

Detection of amyloid in abdominal fat pad aspirates in early amyloidosis: Role of electron microscopy and Congo red stained cell block sections

BACKGROUND Fine-needle aspiration biopsy (FNA) of the abdominal fat pad is a minimally invasive procedure to demonstrate tissue deposits of amyloid. However, protocols to evaluate amyloid in fat pad aspirates are not standardized, especially for detecting scant amyloid in early disease. MATERIALS AND METHODS We studied abdominal fat pad aspirates from 33 randomly selected patients in whom sub...

Percutaneous Lung Biopsy in the Molecular Profiling Era: A Survey of Current Practices.

PURPOSE This study aimed to assess the current practice patterns of radiologists performing percutaneous lung biopsies. MATERIALS AND METHODS This cross-sectional study used a web-based survey sent to the Society of Thoracic Radiology membership from August to October 2015. Responses were collected anonymously, and results were tallied. RESULTS A total of 244 Society of Thoracic Radiology m...

Telomerase activity in transthoracic fine-needle biopsy aspirates as a marker of peripheral lung cancer Running title: Telomerase activity in fine-needle biopsy aspirates

Rapid KRAS, EGFR, BRAF and PIK3CA Mutation Analysis of Fine Needle Aspirates from Non-Small-Cell Lung Cancer Using Allele-Specific qPCR

Endobronchial Ultrasound Guided Transbronchial Needle Aspiration (EBUS-TBNA) and Trans-esophageal Ultrasound Scanning with Fine Needle Aspiration (EUS-FNA) are important, novel techniques for the diagnosis and staging of non-small cell lung cancer (NSCLC) that have been incorporated into lung cancer staging guidelines. To guide and optimize treatment decisions, especially for NSCLC patients in ...

Concentration of fine needle aspirates similar to molecular method improves sensitivity of the diagnosis of tuberculous lymphadenitis in Addis Ababa, Ethiopia

BACKGROUND Tuberculous lymphadenitis (TBLN) diagnosis has been a true challenge solely by clinical evidence in developing countries, due to limited the diagnostic facility on hand. However, the availability and affordability of available diagnostic tools in resource-limited settings like Ethiopia necessitates the quest for other techniques with added value over direct Z-N microscopy. Therefore,...
