BACKGROUND The quality of liver biopsy specimens obtained with different fine needle biopsy (FNB) techniques has not been compared. OBJECTIVES This study was performed to evaluate the diagnostic quality of three different liver FNB biopsy techniques. MATERIALS AND METHODS Two sequential biopsy series were performed on piglets. Three biopsy techniques were compared: capillary-FNB, core-FNB (...

Purpose : Determination of the effectiveness using a vacuum fine-needle aspiration biopsy compared to biopsy. Material and methods An original experimental sample has been developed for performing Also in course study, an improvement device was carried out, associated with peculiarity high pressure (over –0.5 bar), consisting throwing cytological material from needle directly into lumen syringe...

A qualified (indeterminate) diagnosis (QD), such as "suggestive of malignancy," is thought to complicate patient management by heightening clinical uncertainty. We report that QDs increase the overall effectiveness of renal, thyroid, and breast fine-needle aspiration (FNA) biopsy and that the probability that a qualified diagnosis is negative (QDN) can be predicted by the formula QDN = number o...

Introduction Marrow biopsy by surgical trephine is an older procedure than needle aspiration. It is only since the late 1950s that core needle biopsy of the bone marrow has been widely used. Since that time, it has had a considerable effect on diagnostic haematology, pathology and oncology. Wide acceptance is associated with the introduction of a simple procedure using the Jamshidi needle to im...

PURPOSE We aimed to investigate the effectiveness and complications of transthoracic CT-guided biopsy techniques. METHODS A total of 94 CT-guided percutaneous transthoracic biopsy procedures performed in 85 patients were retrospectively evaluated. Core biopsy technique was used in 87 procedures and transthoracic fine-needle aspiration biopsy was used in seven procedures. RESULTS Diagnostic ...

Background: Male infertility is a common problem and needs a minimally invasive method to arrive at the appropriate diagnosis. Alternative to open testicular biopsy the fine needle aspiration cytology of the testis is being increasingly used as a minimally invasive method of evaluating testicular function. Aim of the study: To assess the diagnostic accuracy of fine needle aspiration cytology in...

BACKGROUND: The axillary lymph node status is one of the most relevant prognostic factors in breast cancer. The noninvasive investigation of axillary lymph node involvement in the preoperative diagnosis is one of the greatest challenges in the treatment of breast cancer. The aim of our study is to assess the significance of preoperative axillary diagnostics. It will be verified whether the axil...

BACKGROUND Plasmoblastic lymphoma is a rare and aggressive subtype of diffuse large B cell lymphoma, which occurs usually in the jaw of immunocompromised subjects. CASE PRESENTATION We describe the occurrence of plasmoblastic lymphoma in the mediastinum and chest wall skin of an human immunodeficiency virus-negative 63-year-old Caucasian man who had had polycytemia vera 7 years before. At adm...

OBJECTIVE The objective of this study was to evaluate and compare the diagnostic value of the open biopsy technique and the percutaneous biopsy techniques in lumbar spondylodiscitis. METHODS Between January 2004 and December 2009, we retrospectively reviewed the medical records of 57 patients with infectious lumbar spondylodiscitis. The etiologic diagnosis of the infectious spondylodiscitis w...
