BACKGROUND Stellate ganglion block is usually performed at the transverse process of C6, because the vertebral artery is located anterior to the transverse process of C7. The purpose of this study is to estimate the location of the transverse process of C6 using the cricoid cartilage in the performance of stellate ganglion block. METHODS We reviewed cervical lateral neutral-flexion-extension ...

This paper focuses on a block cipher adaptation of the Galois Extension Fields (GEF) combination technique for PRNGs and targets application in Internet Things (IoT) space, an area where was concluded as quality stream cipher. Electronic Codebook (ECB) Cipher Feedback (CFB) variations cryptographic algorithm are discussed. Both modes offer computationally efficient, scalable algorithms use over...

The Americanjoumal a/Occupational Therapy T he proXimal interphalangeal (PIP) joint is particularly susceptible to acute ligamentous injury, and such an injury can result in swelling without ligament laXity, collateral ligament laXity and disruption, or a partial or complete avulsion of the volar plate with or without bony involvement. Many articles have been written about methods for treatment...

Mallet fingers with an avulsion fracture of the distal phalanx or rupture of the terminal tendon of the extensor mechanism is known as a common injury, while mallet thumb is very rare. In this paper, the case of a 19-year-old woman with a sprained left thumb sustained while playing basketball is presented. Plain radiographs and computed tomography revealed an avulsion fracture involving more th...

We treated 32 displaced mallet finger fractures by a two extension block Kirschner-wire technique. The clinical and radiological outcomes were evaluated at a mean follow-up of 49 months (25 to 84). The mean joint surface involvement was 38.4% (33% to 50%) and 18 patients (56%) had accompanying joint subluxation. All 32 fractures united with a mean time to union of 6.2 weeks (5.1 to 8.2). Congru...

Large number of watermarks is crucial for some real watermarking applications, such as transaction tracking. The purpose of this paper is to enlarge the set of structured watermarks based on balanced incomplete block designs (BIBD). An approach is proposed to generate new structured watermarks by combining existing BIBD-based watermarks. The corresponding recognition rules for the new set of wa...

BACKGROUND A line of block in the right atrium (RA) between the venae cavae is necessary to obtain classic atrial flutter (AFL). We tested the hypothesis that the location of that line of block would determine whether the AFL reentrant circuit would be due to single-loop reentry or figure-of-8 reentry. METHODS AND RESULTS Simultaneous mapping from 392 sites (both atria and the atrial septum) ...
