بیمار خانم 58 ساله ای بود که با شکایت بزرگی قدام گردن و علائم انسداد راه هوایی فوقانی، در بیمارستان حضرت سول اکرم(ص) بستری شده بود. در رادیوگرافی قدامی خلفی و جانبی گردن فشردگی راه هوایی مشاهده گردید که در سونوگرافی و سی تی اسکن نیز، وجود یک توده در ناحیه پارارتروفارنکس، تا ناحیه قدام درمحل تیروئید و به ابعاد10×5/4 سانتیمترتأیید شد.پس از انجام آسپراسیون سوزنی ( fna ) و بیوپسی تشخیصی، پلاسموسیتو...
Background and study aims The low sensitivity of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), especially for the diagnosis of serous cystadenomas (SCAs), can be associated with diagnostic uncertainty that can regularly lead to unnecessary surgical procedures. Needle-based confocal laser endomicroscopy (nCLE) used with EUS-FNA improves diagnostic accuracy, helping to reduce un...
Introduction of endoscopic ultrasound (EUS) to medical practice has brought a huge change in diagnostic algorithm of many gastrointestinal diseases. Addition of EUS-guided fine needle aspiration (FNA) upgraded diagnostic power of EUS. In this focused review series, value of EUS-FNA in the diagnosis of various diseases and tips for getting the best results with EUS-FNA are described by four invi...
Background: In Colombia, thyroid cancer is the 7th in incidence and mortality for both sexes. Currently fine needle aspiration (FNA) most used method studying nodular lesions of thyroid.
 Objective: Describe characteristics a sample surgical specimens histopathological diagnostic centre located an intermediate city, correlate PTC variants calculate accuracy FNA

Cystic change in metastatic lymph nodes of papillary thyroid carcinoma (PTC) is a diagnostic challenge for fine needle aspiration (FNA) because of the scant cellularity. The aim of this study was to evaluate the measurement of thyroglobulin in fine needle aspirate (Tg-FNA) for detecting metastatic PTC in patients with cystic neck lesions and to validate the optimal cutoff value of Tg-FNA. A tot...
BACKGROUND Five percent of pancreatic neoplasms are non- adenocarcinoma tumors. Clinical presentation and imaging characteristics of these tumors are similar to adenocarcinoma. This study aims at evaluating the results and efficacy of Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) in diagnosing the pancreatic non-adenocarcinoma tumor in patients with solid pancreatic mass. METH...
As the field of assisted reproduction has advanced, many previously untreatable men are now biological fathers. Although finding sperm in men with obstructive azoospermia is not difficult, locating and retrieving spermatozoa in men with non-obstructive azoospermia remains a clinical challenge, largely because sperm production in these men can be patchy or focal in nature. In response to this ch...
Hydrogen sulfide produced by sulfate-reducing bacteria (SRB) in sewers causes odor problems and asset deterioration due to the sulfide-induced concrete corrosion. Free nitrous acid (FNA) was recently demonstrated as a promising antimicrobial agent to alleviate hydrogen sulfide production in sewers. However, details of the antimicrobial mechanisms of FNA are largely unknown. Here, we report the ...
