Objective To determine whether patients with lumbosacral (LS) radiculopathy and peripheral polyneuropathy (PPNP) exhibit sudomotor abnormalities and whether SUDOSCAN (Impeto Medical, Paris, France) can complement nerve conduction study (NCS) and electromyography (EMG).Methods Outpatients with lower extremity dysesthesia underwent electrophysiologic studies and SUDOSCAN. They were classified as normal (group A), LS radiculopathy (group B), or PPNP (group C). Pain severity was measured by the Michigan Neuropathy Screening Instrument (MNSI) and visual analogue scale (VAS). Demographic features, electrochemical skin conductance (ESC) values on hands and feet, and SUDOSCAN-risk scores were analyzed.Results There were no statistical differences in MNSI and VAS among the three groups. Feet-ESC and hands-ESC values in group C were lower than group A and B. SUDOSCAN-risk score in group B and C was higher than group A. With a cut-off at 48 microSiemens of feet-ESC, PPNP was detected with 57.1% sensitivity and 94.2% specificity (area under the curve [AUC]=0.780; 95% confidence interval [CI], 0646–0.915). With a SUDOSCAN-risk score cut-off at 29%, NCS and EMG abnormalities related to LS radiculopathy and PPNP were detected with 64.1% sensitivity and 84.2% specificity (AUC=0.750; 95% CI, 0.674–0.886). Conclusion SUDOSCAN can discriminate outpatients with abnormal electrophysiological findings and sudomotor dysfunction. This technology may be a complementary tool to NCS and EMG in outpatients with lower extremity dysesthesia.

A female patient with incidental inguinal mass was initially diagnosed with Castleman disease (CD) via lymph node biopsy and presented paresthesia of stocking and glove patterns with weakness after two cycles of chemotherapy. Severe and diffuse sensorimotor peripheral polyneuropathy (PPNP) was revealed, and POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) was finally diagnosed according to the diagnostic criteria. Early stages of POEMS syndrome may be misdiagnosed as other diseases such as chronic inflammatory demyelinating polyneuropathy (CIDP). Therefore, accurate diagnosis of this disease is delayed and difficult. For this reason, little early electrophysiological findings have been reported. Here we report early electrophysiological findings of POEMS syndrome, demonstrating the ambiguity of the terminal latency index delay warranting attention.

The first branch of the lateral plantar nerve (FBLPN) typically arises from the lateral plantar nerve (82.1%) and a small mixed motor and sensory nerve, which innervates the abductor digiti quinti muscle. The entrapment of FBLPN accounts for 20% of medial heel pain and is commonly confused with plantar fasciitis, fat pad atrophy, and lumbosacral radiculopathy. Proper diagnosis and management require the use of objective diagnostic tools such as electromyography, magnetic resonance imaging, and ultrasonography. Here we describe the unusual case of a patient misdiagnosed with lumbosacral radiculopathy due to neurogenic symptoms and who was correctly diagnosed with neuropathy of FBLPN by electromyography.
