The axillary brachial plexus block is the most widely performed upper limb block. It is relatively simple to perform and one of the safest approaches to brachial plexus block. With the advent of ultrasound technology, there is a marked improvement in the success rate of the axillary block. This review will focus on the technique of ultrasound guided axillary brachial plexus block.

PURPOSE Although Radiation Therapy Oncology Group protocols have proposed a limiting dose to the brachial plexus for patients undergoing intensity-modulated radiotherapy for head-and-neck cancer, essentially no recommendations exist for the delineation of this structure for treatment planning. METHODS AND MATERIALS Using anatomic texts, radiologic data, and magnetic resonance imaging, a stand...

in upper brachial plexus (c5-c6 or c5-c6-c7 roots) injuries, restoration of elbow flexion is the first aim. several methods have been used to achieve this goal. among these procedures, oberlin’s method (transfer of part of ulnar nerve to the nerve to biceps muscle) is the newest one. from april 2002 to march 2003 we used this method in 9 cases, 8 males and 1 female, of upper brachial plexus inj...

CPCs are a relatively common finding during the second trimester sonography. when a choroid plexus cyst is identified, the presence of structural malformation and other sonographic markers of aneuploidy should be assessed with a detailed fetal anatomic survey performed by an experienced person. if no other sonographic abnormalities are present, the CPC is considered isolated. given the consider...

1. Lignocaine readily passes from blood into cerebrospinal fluid. The isolated rabbit choroid plexus, a locus of the blood-cerebrospinal fluid barrier, accumulated [14C]lignocaine by two processess: an active, saturable transport process and a non-saturable process. 2. The accumulation of [14C]lignocaine by choroid plexus was not due to non-specific binding or metabolism of lignocaine within or...

The author reports a rare case of brachial plexus infiltration by non-Hodgkin's lymphoma. T2-weighted MRI showed high signal intensity along the right brachial plexus and soft tissue masses. Ga-67 scintigraphy showed abnormal tracer uptake along the course of the right brachial plexus, and was superior to MRI in detecting the abnormality.

We report two neutropenic patients with Stomatococcus mucilaginosus meningitis and choroid plexus involvement on neuroimaging studies. CT and MR showed abnormal enlargement of the choroid plexus in one lateral ventricle and intense enhancement. In one patient there was edema in the periventricular white matter adjacent to the involved choroid plexus; in both patients there was enhancement of th...

The choroid plexus epithelium secretes electrolytes and fluid in the brain ventricular lumen at high rates. Several channels and ion carriers have been identified as likely mediators of this transport in rodent choroid plexus. This study aimed to map several of these proteins to the human choroid plexus. Immunoperoxidase-histochemistry was employed to determine the cellular and subcellular loca...

It is well known that multiparas who had previously been delivered of newborns with obstetric brachial plexus palsy are at risk of having the same complication in subsequent deliveries. However, none of the studies in the literature have actually attempted to estimate how high is that risk. The aims of the current paper were to investigate obstetric brachial plexus injury in subsequent deliveri...

The p73 proteins are present in different kinds of cells of the central nervous system, such as the choroid plexus, circumventricular structures and neuroepithelium. It has been reported that spontaneously hypertensive rats show ventricular dilation, changes in cerebrospinal fluid proteins and variations in the circumventricular structures such as the organum vasculosum of the lamina terminalis...
