BACKGROUND A solid pseudopapillary tumour of the pancreas (SPTP) is a rare neoplasm. AIM We herein present five cases of SPTP diagnosed using endoscopic ultrasound (EUS) guided fine-needle biopsy (FNB) using a needle with side fenestration (ProCore-needle). METHODS From January 2011 to June 2012 in five patients with SPTP tissue acquisition was carried out with a 19-gauge (4 patients) or a ...
The incidence of epidural needle-induced post-dural puncture headache (PDPH) in parturients following dural puncture with a large bore (18-gauge) needle has been reported to range 76-85%. We describe seven cases in which the performance of epidural anesthesia in parturients was complicated by an unintentional dural puncture with an 18-gauge epidural needle. In all seven cases, the unintentional...
BACKGROUND AND STUDY AIMS Although Endoscopic Ultrasound (EUS)-guided tissue sampling is widely used, the optimal sampling strategy remains subject of debate. We evaluated practice patterns within the international endosonographic community. PATIENTS AND METHODS An online questionnaire was sent to 400 endosonographers from the United States, Europe, and Asia. RESULTS A total of 186 (47 %) e...
Calcium phosphate cement (CPC) sets in situ and forms apatite with excellent osteoconductivity and bone-replacement capability. The objectives of this study were to formulate an injectable tetracalcium phosphate-dicalcium phosphate cement (CPC(D)), and investigate the powder/liquid ratio and needle-size effects. The injection force (mean +/- SD; n = 4) to extrude the paste increased from (8 +/-...
OBJECTIVE We wanted to assess the need for surgical excising papillary lesions of the breast that were diagnosed upon sonographically guided 14-gauge core needle biopsy. MATERIALS AND METHODS Sixty-nine women (age range: 25-74 years, mean age: 51.7 years) with 69 papillary lesions (4.9%) were diagnosed and followed after performing sonographically guided 14-gauge core needle biopsies. Surgica...
BACKGROUND The Gleason score has been shown to offer important information with regard to prognosis and therapy for patients with adenocarcinoma of the prostate gland. In this study, Gleason scores, as determined by 18-gauge core needle biopsies, were compared with both Gleason scores and the pathological staging of corresponding radical prostatectomy specimens. METHODS Records of 78 consecut...
construction and application of a small, light, inexpensive swivel joint suitable for infusions of small laboratory animals is described. Commercially available tubes and needles are used in the construction of the swivel thus making it easy to prepare and essentially disposable. This swivel is especially useful in long-and short-term infusions of pharmaca and nutrients in the general circulati...
BACKGROUND AND AIMS EUS-guided liver biopsy is an emerging method of liver tissue acquisition which is safe and had been shown to produce excellent histological yield. There is limited data comparing the diagnostic yield of different FNA needles. We aimed to compare the diagnostic performance of four commercially available 19-gauge FNA needles. METHODS Four FNA needles and one percutaneous ne...
