Conventional transbronchial needle aspiration (TBNA) using 19-gauge needles can obtain larger histological specimens for hilar-mediastinal diagnosis. A new 19-gauge eXcelon needle was introduced in Taiwan in July 2012. We prospectively enrolled patients with hilar-mediastinal lesions and pathology results of suspected benign origin or lymphoproliferative processes, to perform TBNA using a 19-ga...

i have carried out 22 biopsies in 20 patients, in fifteen i used a vim _ silverman needle, and in the remainder a curetting type needle, in 12 cases (60%) the diagnosis that was made; in 3 cases, inadequate tissue, was obtained; in two cases a fibromuscular tissue, in one case a fatty tissue and in one case the specimen was of hepatic tissue. even with the small biopsy specimen obtained with th...

Using three surveys, a comparative assessment of needle performance and patient preference for 27-gauge (G) and 29G needles for glatiramer acetate administration for multiple sclerosis therapy was performed. Eligible patients participated in a specialty pharmacy program and administered glatiramer acetate for ≥1 month. In Survey 1 on the 27G needle, 545 (82.70%) patients reported no needle prob...

The purpose of our study was to evaluate the feasibility and safety of CT-guided percutaneous lung biopsy using two needles in difficult and poorly cooperative patients; and to examine the usefulness of the malpositioned first needle in tissue sampling with a second needle. This study included 17 consecutive patients with unsuccessful first insertion of the biopsy needle in the normal lung pare...

dry weight per area (LWA) and needle density (ND, needle weight per volume) were measured in terminal current-year shoots in a natural canopy of variably sized Picea abies (L.) Karst. trees growing along a light gradient. Needle shape was described as a rhomboid. Needle width (D2) increased with increasing diffuse site factor, ad (relative amount of penetrating diffuse solar radiation), whereas...
