Obstetrical brachial plexus palsy is a disorder of the peripheral nervous system and occurs in as many as 0.4% of infants born. It is associated with shoulder dystocia, use of mechanical extraction, and macrosomia; it occurs more frequently in infants born by vaginal delivery. The unilateral injury to the brachial plexus complex occurs during the delivery phase as lateral traction is applied to the head to permit shoulder clearance. The infant typically presents in the delivery room with decreased active movements of the affected arm and asymmetrical primitive reflex responses...

OBJECTIVE: Gain in elbow flexion in patients with brachial plexus injury is extremely important. The transfer of a fascicle from the ulnar nerve to the motor branch of the musculocutaneous nerve (Oberlin surgery) is a treatment option. However, in some patients, gain in elbow flexion is associated with wrist and finger flexion. This study aimed to assess the frequency of this association and the functional behavior of the limb. METHODS: Case-control study of 18 patients who underwent the Oberlin surgery...

BACKGROUND: Little attention has been given to neurologic complications after shoulder joint replacement (SJR). Previously thought to occur infrequently, it is likely that many are not clinically recognized, and they can result in postoperative morbidity and impair the patient's recovery. The purpose of this study was to document the prevalence of nerve complications after SJR, to identify the nerves involved, and to define patient outcomes. METHODS: This was a retrospective review of 211 SJRs in 202 patients during a 5-year period were included, with 89 male and 122 female patients at an average age of 70 years...

Guennadi Saiko
In this work, we present a model of dynamics of methemoglobin (MetHb) in burn injuries and show that measuring levels of MetHb can distinguish thickness in burn injuries. METHODS: The model of dynamics of MetHb levels in blood of subjects with burn injuries has been developed based on the vascular morphology of the skin. The model contains burn-specific and non-specific components. RESULTS: The model predicts three distinct outcomes: (a) superficial burn, where the superficial plexus is mainly intact, (b) partial thickness burn, where the superficial plexus lies within the zone of coagulation, but the deep plexus is mainly intact, and (c) full depth burn, where the deep plexus lies in the zone of coagulation...

REVIEW
Soo-Jin Oh, C Justin Lee
Bestrophin-1 (Best1) is a calcium-activated anion channel identified from retinal pigment epithelium where human mutations are associated with Best's macular degeneration. Best1 is known to be expressed in a variety of tissues including the brain, and is thought to be involved in many physiological processes. This review focuses on the current state of knowledge on aspects of expression and function of Best1 in the brain. Best1 protein is observed in cortical and hippocampal astrocytes, in cerebellar Bergmann glia and lamellar astrocytes, in thalamic reticular neurons, in meninges and in the epithelial cells of the choroid plexus...

OBJECTIVE: Major histocompatibility complex class I (MHCI), paired-immunoglobulin-like receptor B (PirB) and cluster of differentiation 3ζ (CD3ζ) negatively regulate neuronal plasticity in developing and adult brains. The aim of this study was to evaluate expressive changes of these factors in motor cortical representations of the brachial plexus (MCRBP) after total brachial plexus root avulsion (tBPRA). METHODS: 45 rats were randomly and equally divided into three groups for evaluating mRNA and protein expression levels of MHCI, PirB and CD3ζ: 7 d, 3 m and control...

It is not uncommon for a severe traumatic brachial plexus injury to involve all 5 roots, resulting in a flail upper limb. In such cases, surgical reconstruction is often palliative, providing only rudimentary function. Nerve transfers are the mainstay of reconstructive strategies due to the predominance of root avulsions. Consistent results are obtained only for restoration of shoulder stability and elbow flexion, whereas restoring useful hand function remains a challenge. The transfer of the contralateral C-7 (cC-7) is commonly used in an attempt to restore basic hand function, but results are notoriously unreliable and inconsistent...

Justin M Brown, Mark A Mahan, Ross Mandeville, Bob S Carter
Neurosurgery is experiencing the emergence of a new subspecialty focused on function restoration. New, evolving, and reappraised surgical procedures have provided an opportunity to restore function to many patients with previously undertreated disorders. Candidates for reconstruction were previously limited to those with peripheral nerve and brachial plexus injuries, but this has been expanded to include stroke, spinal cord injury, and a host of other paralyzing disorders affecting both upper and lower motor neurons...

OBJECTIVE Pan-brachial plexus injury (PBPI), involving C5-T1, disproportionately affects young males, causing lifelong disability and decreased quality of life. The restoration of elbow flexion remains a surgical priority for these patients. Within the first 6 months of injury, transfer of spinal accessory nerve (SAN) fascicles via a sural nerve graft or intercostal nerve (ICN) fascicles to the musculocutaneous nerve can restore elbow flexion. Beyond 1 year, free-functioning muscle transplantation (FFMT) of the gracilis muscle can be used to restore elbow flexion...

OBJECTIVE: We report a case of misdiagnosed neuralgic amyotrophy (brachial plexus neuritis, Parsonage-Turner syndrome). Our primary objective is to review the scientific basis for errors in clinical reasoning. CASE REPORT: We herein report a patient in whom signs and symptoms compatible with neuralgic amyotrophy presented after shoulder surgery. The patient's brachial plexopathy was attributed incorrectly as a complication of interscalene brachial plexus block. The true diagnosis was made only after the patient developed neuralgic amyotrophy in the contralateral upper extremity after a subsequent shoulder surgery on that side, this time without a brachial plexus block...

INTRODUCTION: Brachial plexus blockade is a time-tested technique for upper limb surgeries. The classical approach using paresthesia technique is a blind technique and may be associated with a higher failure rate and injury to the nerves and surrounding structures. To avoid some of these problems, use of peripheral nerve stimulator and ultrasound techniques were started which allowed better localization of the nerve/plexus. Ultrasound for supraclavicular brachial plexus block has improved the success rate of the block with excellent localization as well as improved safety margin...

Rectal foreign body insertion is a common condition in emergency surgery, which often requires surgical intervention. Here we report a clinical case of rectal foreign body insertion as a rare cause of persistent lumbosacral plexus injury. A 72-year-old man presented to the emergency department complaining of acute bilateral paraplegia with loss of sensation in both legs, as well as total urinary retention. The patient underwent abdominal computed tomography, which showed a rectal foreign body measuring 13 × 11...
