INTRODUCTION: The aim of this study was to evaluate the diagnostic value of magnetic resonance imaging (MRI) for muscle denervation due to focal lesions of the median nerve and to compare electrophysiological findings with MRI findings. METHODS: Twenty-six patients with electrophysiological studies diagnose for focal lesions of the median nerve were included in this study. Electrophysiological studies and MRI were conducted on 34 patients' hands. Patient hands were divided into two groups based on edema findings revealed by the MRI: group 1 (edema-negative group; n = 24) and group 2 (edema-positive group; n = 10)...

Marcia Ramos-E-Silva, Ana Paula Frade Lima Pinto, Rodrigo Pirmez, Tullia Cuzzi, Sueli Carneiro
In this second part of the series on dermatomyositis, the diagnosis and its criteria with review of autoantibodies, capillaroscopy, imaging exams, histopathology, muscle biopsy, electroneuromyography, and muscular enzymes will be assessed. The association with malignancy, since it is described as paraneoplasic, will be discussed. The different therapeutic options for this disease will also be reported, including for dystrophic calcification, a rare and late complication of dermatomyositis.

AIM: To develop the algorithm of early diagnosis of carpal tunnel syndrome (CTS) at the stage of functional neurological disturbances by expanding diagnostic possibilities of electroneuromyography using artificial compression test. MATERIAL AND METHODS: Parameters of conductivity of the median nerve in 54 patients with finger numbness were analyzed during 3 months before and after compression of the forearm (blood pressure was measured for 1 min). RESULTS AND CONCLUSION: An increase in the latency in motor fibers and a decrease in the amplitude of sensory response were identified in patients with CTS signs and normal electroneuromyographical parameters at baseline...

Carpal tunnel syndrome (CTS), the most common entrapment neuropathy in adulthood, is rare in childhood. The symptoms may differ to those in adults, or may be misinterpreted owing to children's difficulties in expressing themselves. Cases of idiopathic, bilateral CTS under the age of 5 are rare. A 4-year-old girl presented with pain in both hands and difficulty opening them in the morning. Bilateral severe CTS was determined at electroneuromyography (ENMG). Bilateral wrist splints were advised for both hands...

14 pediatric critically ill patients with various infectious pathologies were assessed. Electroneuromyography was carried out in all patients. Polyneuropathy of critical states were revealed in 10 children. It is shown that the frequency of severeform of this state was 40%. Polyneuropathy mostly affects the peripheral nerves of the lower extremities. Polyneuropathy developed typically on 5-7 day from the start of mechanical ventilation.

BACKGROUND: In leprosy, sensory function of nerves is evaluated with monofilaments test and the motor function with voluntary muscle test, however electroneuromyography is considered as the gold-standard tool. OBJECTIVES: This study aimed: i) to evaluate the correlation between clinical tests and electroneuromyography for the diagnosis of leprosy neuropathy; and ii) to identify the prevalence of leprosy neuropathy and the most compromised peripheral nerves in leprosy...

The authors report an exceptional case of an anterior horn syndrome associated with Sjögren's syndrome in a 58-year-old patient with a flaccid tetraparesis revealed by asymmetric atrophy and diffuse fasciculations associated with xerostomia and xerophthalmia. The electroneuromyography objectified a diffuse anterior horn syndrome. The brain MRI and spinal cord were normal. Laboratory tests revealed positive anti-SSA and anti-SSB antibody. The salivary glands biopsy objectified lymphocytic sialadenitis grade 3 of Chisholm...

OBJECTIVE: We describe the phenotype consistent with axonal Charcot-Marie-Tooth disease type 2 (CMT2) in 4 families with a c.197G>T (p.(Gly66Val)) variant in CHCHD10. METHODS: We sequenced the CHCHD10 gene in a cohort of 107 families with CMT2 of unknown etiology. The patients were characterized by clinical examination and electroneuromyography. Muscle MRI and biopsy of the muscle or nerve were performed in selected cases. Neuropathologic autopsy was performed in 1 case...

We present a case of Guyon's canal syndrome caused by a synovial cyst within the left wrist of a 48-year-old female patient. The patient presented pain and paresthesia in the region of the ulnar nerve, with loss of muscle strength and left-hand deformity. Electroneuromyography showed a compression of the ulnar nerve at the wrist level. Surgical decompression of the nerve at Guyon's canal with resection of the cyst was performed. After the surgery, the patient presented an improvement in the pain and paresthesia, as well as an increase in muscle trophism and correction of the deformity...

Parsonage-Turner Syndrome is a rare disease that affects the musculature of the scapular girdle, leading to muscle atrophy and large motor deficit. The etiology is uncertain, but it is believed that infectious and autoimmune factors are involved. The diagnosis is made by exclusion, and the main differential diagnoses are cervical disc hernias, rotator cuff injuries and rheumatic diseases. During diagnostic investigations, we perform laboratory tests, radiographs and MRI on the shoulders and cervical spine, with emphasis on electroneuromyography to help in making a definitive diagnosis...

Clinical and neurophysiologic study covered efficiency of rehabilitation in 40 patients with upper limbs occupational vegetative-sensory polyneuropathy. Each patient underwent infrared thermography and electroneuromyography of hands before and after the treatment. Findings are that post-treatment nerve impulse velocity in right median nerve has improved considerably, thermovisual pictures of both upper limbs also have reliably improved. Electroneuromyography and infrared thermography for evaluation of rehabilitation efficiency are justified...

Guillain-Barré Syndrome (GBS) is rare in infancy, and the diagnosis of atypical forms is difficult in this age range. The main differential diagnoses include congenital neuropathy. Biological and electrophysiological investigations remain important to confirm diagnosis and start treatment quickly. We report the case of an 8-month-old boy who presented with acquired hypotonia due to progressive descending limb paralysis, predominant in the upper limbs, associated with unexplained severe neutropenia. GBS was diagnosed thanks to the association of albuminocytologic dissociation on cerebrospinal fluid and demyelinating sensomotor polyradiculoneuropathy on electroneuromyography...

AIM: To study the influence of sympathectomy on nerve regeneration in human extremities. MATERIAL AND METHODS: Autoneuroplasty was performed in 86 patients with posttraumatic defects of median and ulnar nerves: in 42 cases in combination with sympathectomy (thoracoscopic clipping of Th3-4 sympathetic ganglions) and in 44 cases without sympathectomy. Computer thermography, laser Doppler flowmetry with spectral wavelet-analysis of blood flow oscillations, ultrasonography of nerve trunks and stimulation electroneuromyography were used...

In connected sample, the authors studied changes in state of peripheral nerves (electroneuromyography) and central afferent conduction tracts (somatosensory evoked potentials) in patients with long-term chronic mercury intoxication. The study helped to reveal negative changes in peripheral and central afferent conduction tracts in the patients with long-term chronic mercury intoxication, more marked in 3 period of the study--demyelination of sensory and motor components of peripheral nerves and longer impulse propagation time in conduction tracts of subcortical and cortical structures of somatosensory brain cortex...

In case of peripheral facial palsy, electroneuromyogram of the facial nerve provides an indication of the nature (myelinic and/or axonal) and severity of nerve damage, thereby facilitating establishment of a prognosis, which is favorable for myelin damage, and guarded for severe axonal damage. The initial examination must be carried out during the second week. In case of severe axonal damage, examination results can be monitored at the third, and more particularly the sixth and the twelfth months. Stable neurophysiological data between the sixth and the twelfth months signal damage stability and open the way to possible palliative surgery...
