OBJECTIVES/HYPOTHESIS Fine-needle aspiration (FNA) biopsy and imaging are commonly used in the preoperative assessment of salivary gland mass lesions. The goal of this retrospective study was to clarify the role of FNA and imaging in the workup of salivary gland masses. STUDY DESIGN Retrospective cohort study. METHODS A computer search identified patients with an FNA of a salivary gland les...

OBJECTIVE To determine the diagnostic accuracy of ultrasound guided fine needle aspiration (FNA) cytology and core needle biopsy (CNB) of axillary lymph nodes pre-operatively in newly diagnosed operable primary breast cancer. METHODS An observational study for all patients who underwent pre-operative FNA cytology or CNB during September 2013-August 2014 was conducted at our institution (Count...

BACKGROUND Tumor biopsy for histological diagnosis is required preoperatively and before initiating chemotherapy or radiation therapy for patients with pancreatic cancer (Cancer of the Pancreas: Clinical Practice Guidelines, European Society for Medical Oncology). Endoscopic ultrasound fine-needle aspiration (EUS-FNA) is widely applied to obtain tissue samples for histological examination. Howe...

BACKGROUND Endoscopic ultrasound guided fine needle aspiration biopsy (EUS-FNA) is a recent innovation in the evaluation of gastrointestinal and pulmonary malignancies. AIMS To review the experience with EUS-FNA of a large single centre. METHODS 333 consecutive patients underwent EUS-FNA. Follow up data were available on 327 lesions in 317 patients, including 160 lymph nodes, 144 pancreatic...

BACKGROUND The influence of serum thyroglobulin (Tg) and thyroidectomy status on Tg in fine-needle aspiration cytology (FNAC) washout fluid is unclear. METHODS A total of 282 lymph nodes were prospectively subjected to FNAC, fine-needle aspiration (FNA)-Tg measurement, and frozen and permanent biopsies. We evaluated the diagnostic performance of several predetermined FNA-Tg cutoff values for ...

Molecular testing has acquired a relevant role for diagnostic and prognostic stratification of indeterminate thyroid nodules. Besides the available commercial solutions marketed in United States, various local strategies have been developed last decade. In this setting, modern interventional cytopathologist, physician who performs both aspirate morphologic interpretation plays key correct handl...

BACKGROUND Fine needle aspiration (FNA) of the appendiceal mucocele is generally avoided because of fear that puncture of a distended viscus will lead to rupture or seeding of neoplastic cells and result in localized or diffuse pseudomyxoma peritonei. Cytologic reports regarding FNA of appendiceal mucoceles are virtually nonexistent. CASE A 55-year-old male with a preoperative diagnosis of an...

Introduction Breast cancer accounted for 23.3% of all cancers in women in Kenya during the year 2000-2002 (1). Almost two thirds of these patients presented at advanced stages. Fine needle aspiration (FNA) can be a cost effective tool for an early and rapid diagnosis (2). Facilities for doing FNA are not available to a large population of patients due to shortage of skilled operators and cytopa...

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is well known as a safe diagnostic procedure. We report the first case of pancreatic pseudocyst after EUS-FNA of the pancreatic body mass. A 60-year-old male underwent EUS-FNA for incidentally detected pancreatic solid mass which was suspected as neuroendocrine tumor. Two weeks later, the patient visited emergency room with acute abd...

Using internal carbon source contained in waste activated sludge (WAS) is beneficial for nitrogen removal from wastewater with low carbon/nitrogen ratio, but it is usually limited by sludge disintegration. This study presented a novel strategy based on free nitrous acid (FNA) pretreatment to intensify the release of organic matters from WAS for enhanced denitrification. During FNA pretreatment,...
