Mean-MUNIX and NI were more sensitive than clinical measures at detecting LMN loss in presymptomatic limbs from patients with slowly progressive ALS. Therefore, these electrophysiological biomarkers should be included in early study phases as meaningful outcome measures. Muscle Nerve 58: 204-212, 2018.

elucidate a definitive time frame in which recovery was obtained. In addition, the scope of analysis was limited because of the small sample and lack of controls. However, the time of recovery was similar to that in a previous EMG outcome study. 3 This report describes EMG findings of recovery after decompression of paralabral cysts at the suprascapular or spinoglenoid notch with arthroscopy or ultrasound-guided aspiration. Our results show that neurophysiological findings of nerve entrapment normalized after decompression. Long-term studies with more patients and follow-ups are required to determine time to recovery.We thank Nicole Hurwitz, BS, and Jennifer Cheng, PhD, for their assistance with the manuscript preparation process.Ethical Publication Statement: We confirm that we have read the Journal's position on issues involved in ethical publication and affirm that this report is consistent with those guidelines. 2.

Bariatric surgery is frequently indicated in the treatment of morbid obesity. Previously unreported complications have been associated to this surgery; among them, neurological complications have gained attention. We report the case of a 25-year-old man submitted to gastric surgery for treatment of morbid obesity who developed, two months after surgery, acute proximal weakness in lower limbs. The electroneuromyography revealed axonal peripheral polyneuropathy with predominant proximal involvement. After treatment with immunoglobulin and vitamin supplementation, rapid clinical and neurophysiologic recovery was observed. We describe the clinical and electroneuromyographic features of this case, stressing the difficulty of initial diagnosis, particularly in the differential diagnosis with Guillain-Barré syndrome. We discuss the importance of nutritional follow-up and the eventual indication of routine vitamin supplementation in these patients.

The SSEP latency represents an accessible and reproducible method to investigate the afferent pathways from the genitourinary tract. These results could be used as normative values in studies involving genitourinary neuropathies in order to better clarify voiding and sexual dysfunctions in females.
