Background
Miller-Fisher syndrome (MFS) is characterized by the clinical triad of ophthalmoplegia, ataxia, and areflexia,and is considered a variant form of Guillain-Barre syndrome. Although some cases of delayed-onset facial palsy in MFShave been reported, the characteristics of this facial palsy are poorly described in the literature. Methods: Between 2007and 2010, six patients with MFS were seen at our hospital. Delayed facial palsy, defined as a facial palsy that developedwhile the other symptoms of MFS began to improve following intravenous immunoglobulin treatment, was confirmed in fourpatients. The clinical and electrophysiological characteristics of delayed facial palsy in MFS, as observed in these patients,are described here. Results: Four patients with delayed-onset facial palsy were included. Delayed facial palsy developed 8-16days after initial symptom onset (5-9 days after treatment). Unilateral facial palsy occurred in three patients and asymmetricfacial diplegia in one patient. The House-Brackmann score of facial palsy was grade III in one patient, IV in two patients,and V in one patient. None of the patients complained of posterior auricular pain. Facial nerve conduction studies revealednormal amplitude in all four patients. The blink reflex showed abnormal prolongation in two patients and the absence ofaction potential formation in two patients. Facial palsy resolved completely in all four patients within 3 months. Conclusions:Delayed facial palsy is a frequent symptom in MFS and resolves completely without additional treatment. Thus, standardtreatment and patient reassurance are sufficient in most cases.

Background
The medial plantar nerve (MPN) is a distal branch of the posterior tibial nerve, and various methods of nerveconduction study for MPN have been introduced so far. Hemmi et al described a new method (Hemmi's method) forrecording medial plantar sensory nerve action potentials (SNAPs), which is considered as a simple and reliable method formeasuring medial plantar SNAPs. This study was aimed to establish the normal values for the MPN conduction study amongKoreans and to compare the sensitivities of three different methods for MPN conduction study (Hemmi, Oh, and Saeed'smethod) in detecting evidence of peripheral neuropathy among diabetic patients. Methods: In 27 healthy subjects, MPN conductionstudy using Hemmi
