Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is performed to obtain specimens for pathological analysis. For this procedure, 19-gauge (19G), 22-guage (22G), and 25-guage (25G) needles are available. The needles are classified into aspiration type and biopsy type. A 56-year-old woman underwent upper gastrointestinal endoscopy that showed a 38-mm-diameter submucosal tumor. The el...

Introduction: Endoscopic ultrasound-guided fi ne-needle aspiration (EUS-FNA) plays a well-established role in the diagnostic workup of suspected mediastinal and abdominal malignancy; however the most eff ective type of needle has yet to be determined. Th e SharkCore Fine Needle BiopsyTM (Medtronic) is thought to facilitate acquisition of tissue with intact architecture and allow for rapid needl...

Doppler optical coherence tomography (OCT) can image tissue structure and blood flow at micrometer-scale resolution but has limited imaging depth. We report a novel, linear-scanning, needle-based Doppler OCT system using angle-polished gradient-index or ball-lensed fibers. A prototype system with a 19-guage (diameter of approximately 0.9 mm) echogenic needle is constructed and demonstrates in v...

the pathergy phenomenon (pp) is one of the hallmarks of behcet's disease (bd). it has been reported to be positive from 17.5% to 83% of cases in different studies. pp is used as a diagnosis criterion in the dilsen criteria, the japan criteria, the international criteria, and the iran criteria. it is therefore important to know wether pp is a fix manifestation of the disease or a cyclic manifest...

Introduction: The purpose of the present study was to record their pain sensation and to assess children`s reaction objectively and subjectively while receiving dental local anesthesia with 27- and 30-gauge needles. Methods: Forty children (24 boys and 16 girls) participated in this study. A random double-blinded crossover design was used so that each child served as his or her own control, rec...

Although various devices have been designed to enable the syringe to be held single handed2l 3 4 we have found the "braced thumb method" as described by Webbl56 to be satisfactory. The lump to be aspirated is steadied between the thumb and forefinger of the left hand while a 20 ml syringe with a No. 18 guage (green) needle is held in the right hand. The needle is introduced into the lesion whil...

A new miniaturized glucose oxidase based needle-type glucose microsensor has been developed for subcutaneous glucose monitoring. The sensor is equivalent in shape and size to a 26-guage needle (0.45-mm o.d.) and can be implanted with ease without any incision. The novel configuration greatly facilitates the deposition of enzyme and polymer films so that sensors with characteristics suitable for...

Radical mastectomy is routinely performed under general anaesthesia, but geriatric patients with compromised cardio-pulmonary function are at increased risk of morbidity and mortality. We report successful perioperative management of radical mastectomy with sole paravertebral block in a 92 years old female with compromised cardio-pulmonary function and kyphoscoliotic spine. Single needle thorac...
