BACKGROUND Fine needle aspiration is an important tool for diagnosis and preoperative evaluation of solitary nodules of the lung. It provides a definitive diagnosis in most patients at low cost with minimal trauma. However, because of the nature of the study and the presentation of the cells in a more distorted and incomplete tissue structure than a histological slide, false positive results ca...

Accurate staging and restaging of primary tumour and mediastinal nodes in patients with lung cancer is of significant importance. For primary tumours, computed tomography (CT) scans of the chest are recommended. Positron emission tomography (PET) imaging should be used in patients with curative intent treatment to evaluate metastatic disease. Diagnosis of the primary tumour should be performed ...

BACKGROUND Peritonsillar abscess is a common infection presenting as a collection of pus in the peritonsillar area. The condition is characterised by a severe sore throat, difficulty in swallowing and pain on swallowing, fever and malaise, and trismus. Needle aspiration and incision and drainage are the two main treatment modalities currently used in the treatment of this condition. The effecti...

BACKGROUND AND AIMS Dentists administer thousands of local anesthetic injections every day. Injection to a highly vascular area such as pterygomandibular space during an inferior alveolar nerve block has a high risk of intravascular needle entrance. Accidental intravascular injection of local anesthetic agent with vasoconstrictor may result in cardiovascular and central nervous system toxicity,...

BACKGROUND The molecular work-up of thyroid nodules from fine needle aspiration samples has given clinicians a new level of diagnostic information. The aim of the present study was to evaluate the utility of molecular analysis in thyroid fine needle aspiration samples from a Chinese population. METHODS Specimens were collected from thyroid nodules by fine needle aspiration. Cytology diagnosis...

BACKGROUND/AIMS Tuberculous peritonitis is prevalent in developing countries and its diagnosis is still challenging due to the lack of specific clinical characteristics and the difficulty in obtaining tissue from the peritoneum without laparoscopy. Endoscopic ultrasound - guided fine needle aspiration is emerging as the most effective and safe method for obtaining tissue from the structures sur...

Background: Lymph node tuberculosis (LNTB) is the leading form of extra pulmonary tuberculosis and common in our country. Acid Fast Bacilli (AFB) detection by Ziehl-Neelsen (ZN) method in the fine needle aspirate from these lymph nodes is confirmatory. Objective: To assess the diagnostic utility of Ziehl-Neelsen staining in lymphadenopathy cases, since it is commonly used method in the diagnosi...

Background and Objectives:Breast cancer is the most common cancer among women worldwide. Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast le...

background : invasive ductal carcinoma is one of the most common type of tumors in females, constituting a single large group of breast cancers. there are various prognostic factors, of which tumor grade, size and axillary lymph node metastasis are among the important ones. fine needle aspiration cytology is a commonly used diagnostic technique in the initial evaluation of breast lumps. in the ...

Background Context. Computed tomography- (CT-) guided fine-needle aspiration biopsy of the vertebral body is an important tool in the diagnostic evaluation of vertebral osteomyelitis. The procedure is considered simple to perform and it is considered a safe procedure with few complications. Purpose. The purpose of this study was to describe an unusual complication due to a CT-guided fine-needle...
