https://www.readbyqxmd.com/read/28528897/lateral-lumbar-interbody-fusion-at-the-lumbosacral-junction
#1
Timothy L T Siu, Kainu Lin
Due to the obstruction of the iliac crest and the retroperitoneal vessels, lateral lumbar interbody fusion (LLIF) is generally considered contraindicated at the lumbosacral junction (LSJ). In particular the 'rise' of the psoas from the vertebral column in the lower lumbar segments has been associated with significant overlap of the lumbar plexus with the vertebral body and exclusion of a safe transpsoas entry. However in selected individuals anatomical variations may help circumvent the difficulties and the anatomical corridor posterior to the lumbar plexus may provide an alternative to the conventional anterior approach...

BACKGROUND: Clonidine, an α-2 agonist, has long been used as a local anesthetic adjunct with proven efficacy to prolong peripheral nerve block duration. Dexmedetomidine, a newer α-2 agonist, has a more favorable pharmacodynamic and safety profile; however, data comparing its efficacy as an adjunct to that of clonidine are inconsistent. We sought to compare the clinical efficacy of these 2 α-2 agonists by examining their effects on peripheral nerve block characteristics for upper extremity surgery...

Cocaine- and amphetamine-regulated transcript (CART) peptides are widely expressed not only in the brain but also in numerous endocrine/neuroendocrine cells as well as in neurons of the peripheral nervous system. The present study investigated the distribution patterns of CART-like immunoreactivity in the pelvic plexus (PP) of the female pig. The co-expression of CART with principal neurotransmitter markers: choline acetyltransferase (ChAT), tyrosine hydroxylase (TH), serotonin (5-HT) or biologically active neuropeptides: pituitary adenylate cyclase-activating polypeptide (PACAP), substance P (SP), calbindin was analyzed using double immunohistochemical stainings...

BACKGROUND: Promoter methylation of N-myc Downstream-Regulated Gene 4 (NDRG4) in fecal DNA is an established early detection marker for colorectal cancer (CRC). Despite its connection to CRC, NDRG4 is predominantly studied in brain and heart, with little to no knowledge about its expression or role in other organs. In this study, we aimed to determine the whole-body expression of NDRG4, with a focus on the intestinal tract. METHODS: We investigated NDRG4 expression throughout the body by immunohistochemistry, Western Blotting and in situ mRNA hybridization using tissues from NDRG4 wild-type, heterozygous and knockout mice and humans...

While upper limb nerve transfers were first described and performed several years ago, they have seen expanded use in the past 20 years. Initially indicated for surgical repair of brachial plexus injuries with nerve root avulsion, the indications have been extended to post-ganglionic lesions because of the excellent results of certain intraplexus nerve transfers. The traditional nerve repair techniques - primary suture and nerve grafting - form the basis of nerve surgery. Although nerve transfer does not replace them, they are a useful supplement as they provide a targeted approach to reinnervation and recovery of key functions of the upper limb...

We describe the case of a 41-year-old woman with metastatic cervical cancer and a large mass eroding into the pelvis and left lumbosacral plexus. The patient had intractable left lower extremity pain refractory to standard therapies, and she elected to undergo intrathecal neurolysis. A diagnostic intrathecal block was performed at the T11-12 interspace followed by intrathecal neurolysis with 6% phenol in glycerin on a subsequent date. During both procedures, we used a tilting radiolucent orthopedic fracture table to maintain strict left lateral-supine positioning...

INTRODUCTION: Superior hypogastric plexus block (SHGPB) is technically difficult and accurate procedure is required to avoid potential complications. We attempted to determine the reference angles for fluoroscopy-assisted SHGPB and to establish a predictor that can guide to select optimal approach between classic posterior approach and transdiscal approach. METHODS: Abdomino-pelvic CT scans from 268 patients diagnosed with pelvic malignancies were examined. The oblique and axial angles needed for the fluoroscope were measured both for posterior and transdiscal approaches by simulating the needle trajectory on CT imaging...

PURPOSE: To report a case of type 3 neovascular lesion in a patient with retinitis pigmentosa (RP) complicated by macular edema. CASE REPORT: A 78-year-old man with a long follow-up for RP was referred for painless visual acuity decrease in the right eye. Best-corrected visual acuity was 20/125 in the right eye and 20/40 in the left. Fundus examination showed typical RP and macular edema in both eyes. In the right eye, spectral domain optical coherence tomography revealed a marked cystic macular edema associated with disruption of the Bruch membrane/retinal pigment epithelium complex overlying a pigmentary epithelium detachment, with a vascular structure which appeared to originate from the deep capillary plexus and to be connected with the subretinal pigment epithelium space...
