Patients with advanced-stage melanoma harboring a BRAF mutation are candidates for BRAF inhibition as a therapeutic strategy. The use of fine-needle aspiration (FNA) to diagnose metastatic melanoma is increasing. Studies examining the predictive value of BRAF mutation analysis on melanoma FNAs via correlation with follow-up excision findings are lacking. We examined 37 consecutive FNA cases of ...

Free nitrous acid (FNA), which is the protonated form of nitrite and inevitably produced during biological nitrogen removal, has been demonstrated to strongly inhibit the activity of polyphosphate accumulating organisms (PAOs). Herein we reported an efficient process for wastewater treatment, i.e., the oxic/anoxic/oxic/extended-idle process to mitigate the generation of FNA and its inhibition o...

BACKGROUND No study on ultrasound-guided fine-needle aspiration (US-FNA) for the diagnosis of retrojugular lymph node has been reported. The present study aimed to introduce US-FNA techniques for retrojugular lymph node and to evaluate their efficacy. METHODS Of the 788 patients who underwent US-FNA of the cervical lymph node, 41 patients underwent US-FNAs of retrojugular lymph node and were ...

The evaluation of a solitary pulmonary nodule (SPN) has changed over the years with increased access to percutaneous computerised tomography (CT) guided fine needle aspiration (FNA), where bronchoscopy is unhelpful. The aim of our study was to evaluate the sample adequacy, diagnostic and complication rate of CT-FNA of a SPN at our academic teaching hospital over an 18 month period. CT-FNA was p...

RATIONALE There is currently no consensus on the ideal method for obtaining deep tissue biopsy material of advanced gastric LP. EUS-FNA has potential as a useful diagnostic method. Thus, we report the case of a 46-year-old male with advanced gastric linitis plastica (LP) who was diagnosed using endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). PATIENT CONCERNS The patient underwe...

Free nitrous acid (FNA) serving as a pretreatment is an effective approach to accelerate sludge disintegration. Also, sodium dodecylbenzene sulfonate (SDBS), a type of surfactants, has been determined at significant levels in sewage sludge, which thereby affects the characteristics of sludge. Both FNA pretreatment and sludge SDBS levels can affect short-chain fatty acid (SCFA) generation from s...

Partially cystic thyroid nodules (PCTNs) are common on ultrasound (US). However, there are insufficient data on the prevalence of thyroid carcinoma among such nodules. The purpose of this study was thus to evaluate the prevalence and differentiation of partially cystic thyroid cancers in US-guided fine needle aspiration (FNA).A total of 1342 consecutive patients with 1360 thyroid nodules underw...

Fine needle aspiration (FNA) is a well-established minimally invasive technique for the cytologic evaluation of suspicious mass lesions involving lymph nodes and other organs. The 2008 WHO classification of tumors of hematopoietic and lymphoid tissues utilizes a multiparametric approach based on cytomorphologic, immunophenotypic, and cytogenetic features to classify these tumors (1). This appro...
