Miller Fisher syndrome(MFS) has been the focus of conflicting opinions regarding the peripheral versus the central nature of the site of major neural injury. We present our electrophysiological findings in one case of MFS to help clarify the pattern of peripheral nerve injury in this syndrome. A 45-year-old man visited our hospital due to sudden diplopia. Initial examination revealed internuclear opthalmoplegia. The next day, his symptoms rapidly aggravated to complete external ophthalmoplegia, ataxia, and areflexia with hand and foot numbness. Serial electrophysiological studies were performed. The results of brainstem evoked potential(BAEP) and blink reflex were normal in the serial studies. Motor and sensory nerve conduction study(NCS) were normal findings in second hospital day, but ulnar sensory nerve shows no sensory nerve action potential(SNAP) and sural sensory conduction velocity was delayed in 7th hospital day. Our patient's clinical presentation began to improve on 15th hospital day, and his electrophysiologic study showed improvement on 29th hospital day. We believe that all the manifestations of MFS can be explained by the involvement of peripheral nerves without brainstem or cerebellar lesion with the serial electrophysiological studies.

Peripheral facial nerve palsy is a neurological condition/disease characterized by unilateral paralysis of the facial muscles. We report the effects of complex Korean medicine treatment in 2 patients diagnosed with Bell's palsy who developed symptoms 3-4 days following vaccination with ChAdOx1 nCoV-19 and who received oral steroids and antiviral medications. Complex Korean medicine treatments including acupuncture, electroacupuncture, bee venom acupuncture, cupping therapy, herbal medicine, and physical therapy were performed. Symptom improvement was evaluated daily using the Numerical Rating Scale, House-Brackmann Grade, and Yanagihara's Score. Patient 1 was hospitalized for 22 days and Patient 2 visited the outpatient clinic 20 times. In both cases, postauricular pain caused by Bell's palsy disappeared, and symptoms of facial paralysis improved following completion of treatment. These findings could suggest that combined Korean medicine treatment may improve symptoms of peripheral facial nerve palsy.

A patient with sequelae of peripheral facial nerve palsy (FNP) was mainly treated with facial chuna manual therapy (FCMT) for over 6 months. The patient was diagnosed with hemophilia B and C, so invasive treatments, such as acupuncture and pharmacopuncture, were precluded. The facial nerve grading system 2.0 (FNGS) and the House-Brackmann Grading Scale (HBGS), Peitersen, Murata, Mehta, and numeric rating scale (NRS) systems were used to measure treatment effectiveness. Each scale showed improvement: FNGS, 3 to 2; HBGS, 3 to 2; Peitersen scale, 2 to 1; Murata scale, 9 to 4; Mehta scale, 14 to 1; and NRS, 8.5 to 2.5. An overall improvement was evident in facial muscle strength, particularly in synkinesis. If acupuncture and pharmacopuncture are unavailable, FCMT alone may be effective in treating FNP sequelae.

Objectives : This study was aimed to investigate the therapeutic effect of Bogijetongtanggammi-bang (BJTG) on injury of the peripheral nerve tissues. Methods : Rats were divided into 2 groups. The rats of the first group were injected with Taxol (1.25 mg/kg) to their sciatic nerves, once each. The sciatic nerves of the rats of the second group were crushed by forcept for 30 seconds. Rats were administered with BJTG (400 mg/kg) or 0.9% saline for 5 days. Changes of DRG neurons, Schwann cells, Cdc2, caspase 3. phospho-p44/42 Erk1/2, phospho-vimentin and ${\beta}1$ integrin were observed by fluorescent microscope and analysed in western blot. Results : In Taxol-treated SD rat models, BJTG up-regulated neurite outgrowth, Schwann cells, Cdc2 and phospho-Erk1/2, and down-regulated caspase 3. In pressure-injured rat models, BJTG up-regulated axons of sciatic nerve, Schwann cells, Cdc2, phospho-vimentin, ${\beta}1$ integrin, and down-regulated caspase 3. Conclusions : Taken together, BJTG was promotive of nerve regeneration on SNI as well as Taxol-induced nerve injury. BJTG had a pharmaceutical property enhancing recovery of injured peripheral nerves and could be a candidate for drug development after further research.

Neurotoxicity in the workplace may occur with exposure to scores of chemicals. Although large acute outbreaks of the occupational neurological disease are rare, the incidence of occupational neurotoxicity in its subtler aspects is unknown. A working knowledge of both the major occupational neurotoxic solvents and the tools used by cliniical neurologists and neurotoxicologists to evaluate neurotoxicity in working populations is a necessity fur the occupational physician. To investigate the effects of carbon disulfide($CS_2$) on the peripheral nerve system using the nervous conduction study, 105 male workers working in the spinning room of a viscose rayon factory were examined and compared with a sex and age matched, unexposed 105 male controls using t-test analysis. 72.4% of $CS_2$-exposed workers complained of neurological symptoms, and the abnormal cases in nerve conduction study were 48.6%. The abnormal cases of nerve conduction study increased in number according as the age and duration of exposure increased. In this study, asymptomatic workers were confirmed to have subclinical neuropathy by nerve conduction study. Also as there were abnormal cases even in its duration of exposure below 4 years, nerve conduction study turned out to be ways of discovering of early peripheral neuropathy. In nerve conduction study, the amplitude, velocity, F-wave latency and H-reflex of the motor and sensory nerves in both upper and lower extremities were significant different between $CS_2$-exposed workers and the controls. From the pathological viewpoint, both segmental and axonal degenerations were assumed in this study.

Diabetes mellitus (DM) leads to a variety of complications and thus we have retrospectively studied to investigate problems of nerve conduction velocity (NCV) study and the heart in the patients with type-II DM. Blood glucose and blood pressure levels were higher in DM group than in Non-DM group. We found that several latencies were delayed in motor conduction study of upper (median and ulnar nerve) and lower extremities (peroneal and tibial nerve), whereas amplitudes and NCVs were decreased in DM group compared with Non-DM group. Latencies of sensory conduction study in upper and lower extremities (sural nerve) were delayed, while amplitudes and NCVs were lower in DM group than in Non-DM group. Abnormal percent of the electrocardiogram was higher in DM group than in Non-DM group. This retrospective study suggests that type-II DM can cause a damage effect on the peripheral nerve and the heart function.

While axons in the peripheral nerve can regenerate and lead to functional recovery to a certain extent after injury, its efficacy varies depending on the severity and duration of the injury. Here, we investigated the effects of Boyanghwano-tang (BYHOT) treatment on the regenerative responses in the sciatic nerves after prolonged transection and coaptation surgery. In mice given crush injury, axonal regeneration was completed when analyzed 1 week later and did not show any difference in regenerative reponses in the distal portion of the nerve between saline- and BYHOT-treated groups. In animal models with transection and reconnection, axonal regeneration was markedly retarded compared to animals with crush injury. Regenerating axons were extended into the reconnected distal portion of the nerve more actively in animals treated with BYHOT than saline controls. Cdc2 protein was similarly induced in nerves with crush injury and with transection and recollection, and its level was lower in BYHOT-treated animal than saline control when measured 2 weeks after nerve reconnection. These results suggest that BYHOT may be useful to promote axonal regeneration in the peripheral nerve after severe injury.

The sciatic nerve is the largest nerve among the peripheral nerves, and the damage to the sciatic nerve is caused by mechanical and physical pressure. This is an important disease that consumes a lot of time and money in the treatment process. Among them, research on relieving nerve pain caused by damage to the peripheral sciatic nerve has been made efforts to prevent and treat this disease through various methods such as drugs, natural products, electrical stimulation, exercise therapy, and massage. Existing treatments are not very effective in neurological pain, and countermeasures are needed. Forsythia Fructus, used in this study, has been used as a therapeutic agent for infectious diseases and a pain reliever for cancer from the past, and in past studies, it has been known to properly control the inflammatory response. In this study, rengyolone, a physiologically active substance of Forsythiae Fructus, was administered to rats that caused chronic left nerve pain to verify the pain relief effect. As a result of the experiment, it was found that mechanical pain and cold stimulation pain were significantly reduced in the rengyolone-treated group compared to the non-administered group. In addition, it was found that nerve growth factor (NGF) mRNA expression was significantly reduced and Cyclin-dependent kinase 2 (Cdc2) expression was increased in the rengyolone administration group. This increase in NGF expression is thought to be related to rengyolone's anti-inflammatory regulatory mechanism. It is expected that the reduced NGF was directly involved in pain relief.

Chronic shoulder pain not relieved by either conservative or surgical management is referred to as chronic refractory shoulder pain. This is a retrospective case series where chronic refractory shoulder pain patients were treated either with peripheral nerve stimulation (PNS) or with pulsed radiofrequency (p-RF) therapy to the suprascapular nerve. Both patients receiving PNS reported 100% pain relief for the first month. At the 3- and 6-month follow-ups, one patient continued to experience 100% relief while the other reported 90% relief. One patient undergoing p-RF experienced about 90% pain relief at both 1- and 3-month intervals and 0% relief at the 6-month interval. The other patient with p-RF experienced 33% relief at 1-month and 0% relief thereafter. No patient reported any complications. The results of previous randomized controlled trials evaluating the efficacy of p-RF administered to the suprascapular nerve were mixed, and there is a lack of published studies on PNS effects. Neuromodulation of the suprascapular nerve can be effective for chronic refractory shoulder pain patients. Larger scale randomized controlled trials comparing PNS and p-RF are needed to better understand their respective therapeutic capacity.

Nerve torsion is a rare condition that causes sensory abnormalities and decreased muscle strength due to a nerve-twisting phenomenon in the peripheral nerves. To date, the progression of the condition from its cause to diagnosis and treatment has not been established. The authors report three cases of good results from the treatment of nerve torsion in the anterior interosseous and radial nerves with epineurotomy and neurolysis.
