: In upper (C5-C7) and total (C5-T1) root avulsion brachial plexus injury, a method of double neurotization from a single donor spinal accessory nerve to two target nerves (suprascapular nerve and axillary nerve) may be done, leaving donor nerves available for reconstruction procedures to restore other aspects of upper limb function. A mean range of shoulder abduction of 91° (SD 25°) was achieved through this procedure in our study of 13 cases, of which seven cases were C5-C7 root avulsion and six cases were C5-T1 root avulsion brachial plexus injuries...

REVIEW
Michael D Stubblefield
Radiation fibrosis syndrome describes the multiple neuromuscular, musculoskeletal, visceral, and other late effects that result from radiation-induced fibrosis. Radiation can damage the spinal cord, nerve roots, plexus, local peripheral nerves, and muscles within the radiation field. This constellation is known as a "myelo-radiculo-plexo-neuro-myopathy" and can result in pain, sensory loss, weakness, and other signs and symptoms. Although there is no curative treatment for radiation damage, supportive management of symptoms can be helpful in restoring and maintaining function and quality of life...

While in many cases they are not directly visualized, awareness of the thoracic nerves and their courses at cross-sectional imaging is important for radiologists. An understanding of the normal function of each nerve is important, as many patients present with neurologic signs and symptoms that can be used to reinforce search patterns for disease and detection of supportive radiologic abnormalities. In the case of primary neoplasms, understanding the expected presence of a nerve in the location of a mass can enhance and improve the accuracy of differential diagnoses...

The epidural space is frequently used for placement of the epidural needle, catheter, and various pharmacological agents. The presence of structures in the epidural space such as epidural fat, venous plexus, or ligaments that may lead to uneven distribution of agents within the epidural space have been described.(1-3) Whether these structures are anatomical (such as connective tissue) or functional (due to distortions of actual anatomy secondary to injection of agents epidurally) has been disputed.(2-5) We describe our management of a patient who presented with bilateral radicular symptoms and severe low back pain...

The period of forming of superficial vascular plexus during physiological retinal angiogenesis was shorter in C57Bl/6 mice. Experiments on the model of oxygen-induced retinopathy showed that avascular and vascularized zones in BALB/c mice on day 17 are smaller than in C57Bl/6 mice are by 5 and 1.5 times, respectively. The obtained results confirmed the importance of phenotype of retinal macrophages in the regulation of processes of both physiological and pathological retinal angiogenesis.

REVIEW
Wale Sulaiman, Doan H Nguyen
We review the biology and role of transforming growth factor beta 1 (TGF-β1) in peripheral nerve injury and regeneration, as it relates to injuries to large nerve trunks (i.e., sciatic nerve, brachial plexus), which often leads to suboptimal functional recovery. Experimental studies have suggested that the reason for the lack of functional recovery resides in the lack of sufficient mature axons reaching their targets, which is a result of the loss of the growth-supportive environment provided by the Schwann cells in the distal stump of injured nerves...

MicroRNA (miRNA) expression varies in association with different tissue types and in diseases. Having been found in body fluids including blood and cerebrospinal fluid (CSF), miRNAs constitute potential biomarkers. CSF miRNAs have been proposed as biomarkers for neurodegenerative diseases; however, there is a lack of consensus about the best candidate miRNA biomarkers and there has been variability in results from different research centers, perhaps due to technical factors. Here, we sought to optimize technical parameters for CSF miRNA studies...

Galanin (GAL) is a 30-amino acid neuropeptide that is expressed in both the central and peripheral nervous system, including the enteric nervous system (ENS). Increased GAL concentrations have been identified in the blood of colorectal cancer (CRC) patients. The aim of the present study was to assess whether sections of the colon wall containing ENS plexuses or CRC tumor are associated with increased GAL concentrations. Blood samples were collected from 68 CRC patients and 39 healthy volunteers. In addition, samples of CRC tumors and colon wall tissue in close proximity to and distant from the neoplastic tissue were obtained from 22 CRC patients...

Brain tumours in cattle are uncommon and the spontaneous development of primary brain tumours of different histological types is rare in both man and animals. In man, multiple concurrent primary tumours of different types are occasionally described. We report the rare simultaneous occurrence of two different primary brain tumours, gliosarcoma and choroid plexus carcinoma, diagnosed by microscopical and immunofluorescence evaluation in an 8-year-old cow with a 2-month history of neurological disease. Gliosarcoma is a rare variant of glioblastoma multiforme, characterized by the presence of malignant glial cells and mesenchymal tissue...
