Objective: This study aimed to report the therapeutic effect of acupuncture on chemotherapy-induced peripheral neuropathy (CIPN). Methods: The articles were sourced from databases including PubMed, EMBASE, Cochrane Library, CNKI, CiNii, WHO ICTRP, JSOM, KMBASE, KISS, NDSL, and OASIS as of July 2019. The main search keywords were peripheral neuropathy and acupuncture, and only randomized controlled trials using acupuncture for therapeutic purposes were included. Cochrane's risk of bias was used to assess the risk of bias, and the Review Manager 5.3 program was used for meta-analysis. Results: Six studies with a total 394 participants were included. When combined treatment of acupuncture and usual care was compared with usual care alone, quality of life improved more significantly in the combination treatment group (SMD=-2.71, 95% CI: -5.01 to -0.41, P=0.02, I²=97%). The CIPN pain score was lower among the combination treatment group, but not to a significant degree (SMD=-2.55, 95% CI: -5.14 to 0.04, P<0.05, I²=98%). There were no severe side effects in any studies. Conclusion: Acupuncture combined with usual care may be considered to safely relieve CIPN pain and improve quality of life for cancer patients. However, as there are few randomized controlled trials studying the effect of acupuncture on CIPN, further well-designed research is needed.

Background: Scalding burn injuries can occur in everyday life but occur more frequently in young children. Therefore, it is important to develop more effective burn treatments. Objectives: This study examined the effects of bee venom (BV) stimulation on scalding burn injury-induced nociception in mice as a new treatment for burn pain. Methods: To develop a burn injury model, the right hind paw was immersed temporarily in hot water (65℃, 3 seconds). Immediately after the burn, BV (0.01, 0.02, or 0.1 mg/kg) was injected subcutaneously into the ipsilateral knee area once daily for 14 days. A von Frey test was performed to assess the nociceptive response, and the altered walking parameters were evaluated using an automated gait analysis system. In addition, the peripheral and central expression changes in substance P (Sub P) were measured in the dorsal root ganglion and spinal cord by immunofluorescence. Results: Repeated BV treatment at the 2 higher doses used in this study (0.02 and 0.1 mg/kg) alleviated the pain responses remarkably and recovered the gait performances to the level of acetaminophen (200 mg/kg, intraperitoneal, once daily), which used as the positive control group. Moreover, BV stimulation had an inhibitory effect on the increased expression of Sub P in the peripheral and central nervous systems by a burn injury. Conclusions: These results suggest that a peripheral BV treatment may have positive potency in treating burn-induced pain.

Objective: This study was aimed to report the therapeutic effects of herbal medicine on chemotherapy-induced peripheral neuropathy (CIPN). Methods: The prior studies were searched from the databases included PubMed, Cochrane Library, EMBASE, CNKi, CiNii, KISS, NDSL, KMBASE, and OASIS until September 2020. The main search keywords were chemotherapy, peripheral neuropathy, and herbal medicine, and only randomized controlled trials that analyzed the therapeutic efficacy of herbal medicine were included. The Cochrane's Risk of Bias was used for assessment of the risk of bias and the Review Manager 5.3 program was used for meta-analysis. Meta-analyses were grouped by the administration routes of herbal medicines (oral administration or topical use). Results: Nine studies with a total of 563 participants were included. Compared with usual care, the effective rate was higher in oral administrated herbal medicine (RR 1.67, 95% CI 1.25 to 2.23; p<0.001, I2=31%). In addition, topical herbal medicine showed an significantly higher effective rate than placebo (RR 2.20, 95% CI 1.52 to 3.18; p<0.001, I2=0%) and usual care (RR 2.24, 95% CI 1.74 to 2.89; p<0.001, I2=66%). There was no severe adverse effect in all participants. Conclusions: Herbal medicine appears to improve neuropathy caused by chemotherapy in cancer patients more than conventional therapy of CIPN. However, as there is heterogeneity between the included studies and a lack of blinding, further well-designed researches are more needed.

Background: Clinical spectrum of immunoglobulin M (IgM) monoclonal gammopathy varies from IgM monoclonal gammopathy of unknown significance (IgM-MGUS) to hematological malignancies. We evaluated the clinical features, electrophysiological characteristics, and prognosis of patients with peripheral neuropathy associated with IgM monoclonal gammopathy (PN-IgM MG). Methods: We retrospectively evaluated 25 patients with PN-IgM MG. Peripheral neuropathy was classified as axonal, demyelinating, or undetermined, based on electrophysiological studies. We classified the enrolled patients into the IgM-MGUS and malignancy groups, and compared the clinical and electrophysiological features between the groups. Results: Fifteen patients had IgM-MGUS and 10 had hematologic malignancies (Waldenström's macroglobulinemia: two and B-cell non-Hodgkin's lymphoma: eight). In the electrophysiological evaluation, the nerve conduction study (NCS) criteria for demyelination were met in 86.7% of the IgM-MGUS group and 10.0% of the malignancy group. In particular, the distal latencies of the motor NCS in the IgM-MGUS group were significantly prolonged compared to those in the malignancy group (median, 9.1 ± 5.1 [IgM-MGUS], 4.2 ± 1.3 [malignancy], p = 0.003; ulnar, 5.4 ± 1.9 [IgM-MGUS], 2.9 ± 0.9 [malignancy], p = 0.001; fibular, 9.3 ± 5.1 [IgM-MGUS], 3.8 ± 0.3 [malignancy], p = 0.01; P-posterior tibial, 8.3 ± 5.4 [IgM-MGUS], 4.4 ± 1.0 [malignancy], p = 0.04). Overall treatment responses were significantly worse in the malignancy group than in the IgM-MGUS group (p = 0.004), and the modified Rankin Scale score at the last visit was higher in the malignancy group than in the IgM-MGUS group (2.0 ± 1.1 [IgM-MGUS], 4.2 ± 1.7 [malignancy], p = 0.001), although there was no significant difference at the initial assessment. Conclusions: The risk of hematological malignancy should be carefully assessed in patients with PN-IgM MG without electrophysiological demyelination features.

Stroke is usually associated with the cerebral blood flow of the central nervous system. However, studies concerning the effects of neurologic sysmptoms induced from stroke on the peripheral blood flow has not taken place sufficiently. To ascertain the feasibility of a blood flow meter adopting to use doppler ultrasonogrphy, under the prospect that hemiparesis induced from stroke may have effect on the peripheral blood flow, the peripheral blood flow velocity was observed. The control group made up of healthy people without any factors capable of effecting the peripheral blood flow velocity, and patient group which consist of hemiparetic people induced from stroke, were recruited. Volumes of recruitment are 21 persons in the patient group, and 29 persons in the control group, but the final numbers of people are 17 and 21 respectively because of the inconsistancy in the method of the test. The non-invasive method of Doppler effect of Ultrasound was used to measure the blood flow velocity. The blood flow velocity in the peripheral part of left and right fourth fingers:dorsal branches of proper palmar digital artery to dorsum of distal phalanges, was measured in the control group and patient group through Doppler Ultrasound. In comparison of the control group and the patient group, the systolic blood flow velocity from the peripheral part of the upper extremity was lower in the patient group than that of the control group. According to such results, it is concluded that hemiparesis induces the reduction of the peripheral blood flow velocity in the systolic phase.

Neurofibromatosis type I or Von Recklinghausen's disease can occur at any site in the body. It is characterized by multiple $c\'{a}fe\;\'{a}u\;l\'{a}it$ spots on the skin-more than six spots greater than 1.5cm-, neurofibromas of the peripheral and centarl nervous system, and variety of other dysplastic abnormalities of the skin, bones, endocrine organs, nervous systems, and blood vessels. It is an autosomal dominant trait disease with a frequency of 1 of 3000. Neurofibromatosis is known to be complicated by malignancies. Neurofibromatosis is progressive disease and shows a marked variations in expression in affected individuals. In this report we describe a male patient with neurofibromatosis type I developed in the parapharyngeal space. The patient had huge mass at left parapharyngeal space and inguinal area. We successfully treated the patient with surgery without complication.

The results are as follows. 1. Oriental medical terms which express abnormal sensations are Bulin, Mamok, Mamokbulin. 2. Bulin, Oriental medical terminology, was used from Naegyeong's era to the Song Dynasty era and expressed as one of the symptoms in Jungpung(Stroke), Bi syndrome(Obstruction syndrom of Gi and Hyeol), Wi syndrome(Flaccid paralysis of the limbs), Hyeolbi(One of the Bi syndroms). But since the Keum Dynasty era, Mamok or Mamokbulin were more used than Bulin and that was refered as seperated disease. 3. Ma is paresthesia or dysthesia on the skin and the limbs, and the symtoms are not itchy, patients are felt like insect's crawling or bite. Mok is a stubborn symptom , the patients are felt like tree, which don't know pain and itching sensation. And therefore Ma is similar to positive phenomena and Mok is similar to negative phenomena in clinical aspect. 4. Mamok is GiHyeol(Gi is functional activities, Hyeol is blood) and Gyeonglak(Meridian system)'s disease. It's main causes are Giheo(Deficiency of Gi) and Hyeolhel(dificiency of Blood) and inducing tactors are Pung-Han-Seub(pathogenic wind-cold-dump) and Damtak(Phlegm-turbity), Eohyeol(Stagnated blood). 5. Mamok is induced from mononeuritis, multiple mononeuritis, polyneuropathy in the peripheral nervous lesions and also induced from cervical spondylosis, spinal tumour, multiple sclerosis, cerebrospinal vascular disease in central nervous systems.

The lack of an effective treatment for Alzheimer's disease (AD) stems primarily from incomplete understanding of AD's causes. A rapidly growing number of scientific reports highlight important roles played by peripheral infections and intestinal bacterial flora in pathological and physiological functions involving the microbiome-intestine-brain axis. The microbiome controls basic aspects of the central nervous system (CNS), immunity, and behavior, in health and disease. Changes in the density and composition of the microbiome have been linked to disorders of the immune, endocrine, and nervous systems, including mood changes, depression, increased susceptibility to stressors, and autistic behaviors. There is no doubt that in patients with AD, restoration of the intestinal microbiome to a composition reminiscent of that found in healthy adult humans will significantly slow the progression of neurodegeneration, by ameliorating inflammatory reactions and/or amyloidogenesis. In the near future, better understanding of bidirectional communication between the brain and microbiota will allow the development of functional diets using specific probiotic bacteria.

Pain from nervous or musculoskeletal disorders is one of the most common complaints in clinical practice. Corticosteroids have a high pain-reducing effect, and their injection is generally used to control various types of pain. However, they have various adverse effects including flushing, hyperglycemia, allergic reactions, menstrual changes, immunosuppression, and adrenal suppression. Pulsed radiofrequency (PRF) is known to have a pain-reducing effect similar to that of corticosteroid injection, with nearly no major side effects. Therefore, it has been widely used to treat various types of pain, such as neuropathic, joint, discogenic, and muscle pain. In the current review, we outlined the pain-reducing mechanisms of PRF by reviewing previous studies. When PRF was first introduced, it was supposed to reduce pain by long-term depression of pain signaling from the peripheral nerve to the central nervous system. In addition, deactivation of microglia at the level of the spinal dorsal horn, reduction of proinflammatory cytokines, increased endogenous opioid precursor messenger ribonucleic acid, enhancement of noradrenergic and serotonergic descending pain inhibitory pathways, suppression of excitation of C-afferent fibers, and microscopic damage of nociceptive C- and A-delta fibers have been found to contribute to pain reduction after PRF application. However, the pain-reducing mechanism of PRF has not been clearly and definitely elucidated. Further studies are warranted to clarify the pain-reducing mechanism of PRF.
