and nonpalpable breast lesions is a safe and effective alternative to fine-needle aspiration and needle-localized breast excisional biopsies (1, 2). It can reduce the need for a two-stage procedure and can improve the surgical and oncological outcomes (3). However, one disadvantage of this technique for sampling breast cancer is the possible seeding of malignant tumor cells along the needle tra...

introduction although thyroid nodules are usually benign, malignancy must always be ruled out. many efforts have been made to find. malignant nodules and reduce the number of unnecessary operations. in this study, our aim was to examine, after the more extensive use of fine needle aspiration (fna), whether the incidence of cancer finding has been increased. materials and methods we studied retr...

introduction: this study was conducted at the department of ear, nose, throat, head and neck surgery, post graduate medical institute lady reading hospital peshawar. the duration of the study was one year from june 17, 2009 to june 16, 2010. the sample size was 82 patients with solitary thyroid nodule, fulfilling the inclusion criteria. after taking detailed history, thorough examination, relev...

Background: Abdominal cutaneous and subcutaneous nodules are uncommon benign or malignant lesions. The majority of the malignant nodules are metastatic in origin and may be the initial presentation of a primary malignancy; hence, an early diagnosis is important. Our aim of this study was to find out the spectrum of lesions (both non-neoplastic and neoplastic) that present as cutaneous and subcu...

Effective use of the convex curvilinear ultrasound bronchoscope in the esophagus (EUS-B) is well described. EUS-B has not been described for diagnostic sampling of the left adrenal gland. We describe 6 cases of diagnostic fine-needle aspiration of the left adrenal gland using EUS-B. This capacity increases the diagnostic capabilities of the pulmonologist experienced in EUS-B.

This paper describes a microsystem for automated blood sampling from laboratory mice used in pharmacokinetic studies. Intended to be mounted as a "backpack" on a mouse, it uses a microneedle, reservoir, and an actuator to instantaneously prick the animal for a time-point sample, eliminating the need for a tethered catheter with large dead volume. The blood is collected by capillary effect throu...

BACKGROUND Rapid on-site evaluation (ROSE) can improve adequacy rates of fine-needle aspiration biopsy (FNAB) but increases operational costs. The performance of ROSE relative to fixed sampling depends on many factors. It is not clear when ROSE is less costly than sampling with a fixed number of needle passes. The objective of this study was to determine the conditions under which ROSE is less ...

Background Fine needle aspiration (FNA) is considered the investigation of choice in cytological sampling of thyroid nodules. Non-aspiration fine needle cytology (NAC) has been described as an alternative method with technical and interpretive advantages. This study compares the sampling adequacy and diagnostic accuracy of NAC with FNA in predicting neoplasia and malignancy in thyroid nodules. ...
