Delta-6 desaturase was measured in rat brain microvessels and choroid plexus by incubation in the presence of radioactive linoleic acid. Under our conditions, in 21-day-old animals, delta-6 desaturase was not detected in brain microvessels. In contrast, it was present in choroid plexus (about 21 pmol/min per mg protein). In comparison, the activity in brain was much lower (about 1 pmol/min per ...
Lesions of the brachial plexus may arise for various reasons. Metastatic carcinoma involving the non-ipsilateral brachial plexus is a relatively rare condition. This report presents the case of a 56-year-old woman with brachial plexus carcinoma metastasized from non-ipsilateral breast cancer. After admission, minute examinations were arranged, which gave support to the previous diagnosis. Exten...
A sheet of choroid plexus epithelial cells extends into each cerebral ventricle and secretes signaling factors into the CSF. To evaluate whether differences in the CSF proteome across ventricles arise, in part, from regional differences in choroid plexus gene expression, we defined the transcriptome of lateral ventricle (telencephalic) versus fourth ventricle (hindbrain) choroid plexus. We find...
PURPOSE Secondary hyperparathyroidism (SHPT) develops in patients with chronic renal failure. This study aimed to compare analgesic efficacy in SHPT patients who undergo subtotal parathyroidectomy after superficial versus deep cervical plexus block. METHODS Sixty chronic renal failure patients with SPHT scheduled for subtotal parathyroidectomy were randomized to receive general anesthesia (gr...
BACKGROUND AND OBJECTIVES Local anesthetic spread during interscalenic block has been thoroughly studied, however there are few studies on posterior block. This study aimed at evaluating the spread of different local anesthetic volumes during posterior brachial plexus block using contrasted X-rays. METHODS Participated in this study 16 patients submitted to posterior brachial plexus block, 15...
Magnetic resonance imaging (MRI) of the brachial plexus is the imaging modality of first choice for depicting anatomy and pathology of the brachial plexus. The anatomy of the roots, trunks, divisions and cords is very well depicted due to the inherent contrast differences between the nerves and the surrounding fat. In this pictorial review the technique and the anatomy will be discussed. The fo...
OBJECTIVE To investigate the nature and extent of neurosurgically treated obstetric plexus lesions with obstetric and neonatal precedents. DESIGN Retrospective analysis of prospectively collected data. SETTING Leiden, the Netherlands. POPULATION A 9-year cohort of infants (n = 206) neurosurgically treated for obstetric brachial plexus lesion at a tertiary referral centre for nerve lesions...
Cerebellar granule cells, the most abundant neurons in the mammalian brain, arise in the rhombic lip located at the roof of the brain's fourth ventricle. Bordering the rhombic lip is the choroid plexus, a non-neuronal structure, composed of blood vessels enveloped by epithelial cells. Here, we show a striking decrease in neural differentiation of rhombic lip-derived cells, which failed to exten...
Neurolymphomatosis (NLY) is a type of rare disease with poor prognosis, characterized by infiltration of nerves, nerve roots and plexus. We report a case of 54-years old female patient non-diabetic and normotensive diagnosed with chronic lymphocytic leukemia presented with pain in the neck and arm and numbness in the ipsilateral hand. The patient underwent 18F fluorodeoxyglucose PET/...
The choroid plexus is an important central nervous system (CNS) structure that is often neglected in pathologic and radiologic studies of intracranial diseases. The choroid plexus may serve as 1) a portal of entry for pathogens into the CNS, 2) a target for various systemic disorders, 3) a reflector of various diseases that affect the brain and meninges, or 4) a site of primary processes such a...
