Electrodiagnosis in plexopathies; an update

Electrodiagnosis of brachial plexopathies and proximal upper extremity neuropathies.

This article describes the normal anatomy of the brachial plexus and its major terminal branches, as well as the major causes and clinical presentations of lesions of these structures. An approach to electrodiagnosis of brachial plexopathies and proximal upper extremity neuropathies is provided, with an emphasis on those nerve conduction studies and portions of the needle examination, which per...

Electrodiagnostic testing in lumbosacral plexopathies.

Patients presumed to have lower limb symptoms localizing to the lumbar or lumbosacral plexus require rigorous electrophysiological evaluation. Entities that cause lumbosacral plexopathies may be patchy, asymmetrical and more diffuse than initially suspected. As a result, bilateral nerve conduction studies and needle examination outside those routinely tested and clinically affected may be neede...

Neonatal Sepsis: An Update

Sepsis is the most common cause of neonatal mortality. As per National Neonatal-Perinatal Database (NNPD), 2002-2003, the incidence of neonatal sepsis in India was 30 per 1000 live births. Signs and symptoms of sepsis are nonspecific; therefore empirical antimicrobial therapy is promptly initiated after obtaining appropriate cultures. The early manifestations of neonatal sepsis are vague and il...

Electrodiagnosis in Cranial Botulism

Botulism is an acute neurologic disorder that causes potentially life-threatening neuroparalysis resulting in weakness and laccid paralysis. In addition to the autonomic nervous system, botulism may involve only the cranial nerves, thus posing special diagnostic problems. Almost all cranial nerves are not easily testable. The anatomical and physiological characteristics of the spinal accessory ...
