Purpose: As the interest and demand for esthetics grow up with medical development, the number of patients who want to correct dentofacial deformities by orthognathic surgery has increased. And the success of orthognathic surgery is dependent upon satisfaction of patients in great measure. Therefore the purpose of this study is to examine functional disability, sensory disturbance and esthetic satisfaction of the patients after orthognathic surgery. Material and methods: Among 89 patients who orthognathic surgery was performed at Seoul National University Bundang Hospital during the period from July 2003 to July 2008, 46 patients were considered in the study. Patients were surveyed with questionnaires and visual analogue scale(VAS) which author has designed. The analysis and comparison were performed according to gender, follow up span, and type of surgery based on answer of questionnaires. Results and conclusions: Total satisfaction rate was 76%. And there was statistical significant difference between subjective evaluation of facial esthetics before the surgery and that of after surgery(p<0.05). Differences in occurrence of functional disability, sensory disturbance between groups were not observed. In conclusion, the operator should understand the postoperative self-satisfaction of the patients and complications. If we can communicate with the patients before operation. patients' satisfaction rate will increase after operation.

Objectives & Methods: We investigated 28 books to study etiology and pathology of Son-Bal Jeorim. Result and Conclusion 1. The eiology of Son-Bal Jeorim is same as it of Bee Jeung(痺症). 2. Generally speaking, the cause of Bee Jeung was distributed Wind(風), Coldness(寒), Wetness (濕) of meridian. Bee Jeung can be devided into SilBi(實痺) and HeoBi(虛痺). In SilBi(實痺) there are PungHanSeupBi(風寒濕痺) and YeolBi(熱痺). In HeoBi(虛痺), there are GiHyeolHeoBi(氣血虛痺), EumheoBi(陰虛痺) and YangHeoBi(陽虛痺). 3. Son-Bal Jeorim belong to peripheral neuropathy in western medicine. 4. Syndrome of acute motor paralysis with variable disturbance of sensory and autonomic function, subacute sensorymotor paralysis, syndrome of chronic sensorimotor polyneuropathy, neuropathy with mitochondrial disease, syndrome of mononeuropathy or nerve plexusopathy. 5. Peripheral neuropathy is caused by carpal tunnel syndrome, diabetic neuropathy, uremic neuropathy, hepatic neuropathy, hypothyroid neuropathy, hyperthyroid neuropathy, neuropathy due to malnutrition, neuropathy due to toxic material, neuropathy due to drug, paraneoplastic neuropathy, hereditary neuropathy, etc. 6. Cerebral apoplexy, myelopathy, peripheral circulatory disturbance, anxiety syndrome cause symptoms of peripheral neuropathy

The nasal and zygoma bone are parts of frequently fracturing of facial bones because of anatomically protrusion. Of facial bone fractures, nasal bone is at the high level of incidence rate. But zygoma fracture that anatomical characteristics increase the incidence rate also is occupied considerable part of the facial bone fracture. The outline of face is decided by form of underlying skeletal structure, of that, zygoma plays an important role in. Zygoma is closely attached to surrounding anatomic structure as orbit, maxillary sinus. Aesthetic and functional disturbance are developed by zygoma fracture from trauma, complications, as facial asymmetry, trismus, sensory disturbance, epistaxis, periorbital hemorrhage, diplopia etc, are developed. The patterns of complications following displacement of fractured fragment of zygoma by trauma are slightly different.

Purpose: Peripheral neuropathy accompanied by sensory disturbance, such as limb paralysis and hemiplegia, is mainly caused by acute disseminated encephalomyelitis (ADEM). This case study aimed to determine the effect of ankle strengthening exercises that use proprioceptive neuromuscular facilitation (PNF) on the gait, balance, ankle-control ability, and sit-to-stand ability on a patient with ADEM. Methods: A 10-year-old male with quadriplegia and ankle-control impairment participated in this 4-week training intervention. The patient, diagnosed with ADEM, was treated with ankle strengthening exercises that used PNF. Results: The patient demonstrated improvements in balance, ankle-control ability, sit-to-stand ability, and gait performance. Outcome measures (manual muscle test, modified Ashworth scale, sensory assessment, coordination assessment, Berg balance scale, 5 time sit-to-stand test, and 10 m walk test) were taken before and after the training program. Conclusion: The results of this case suggest that an ankle strengthening exercise that uses PNF can improve the gait, balance, ankle-control ability, and sit-to-stand ability in patients with ADEM. In ADEM, the initial treatment is important, and the use of ankle strengthening exercises with PNF could lead to meaningful results. However, there is limited research due to an insufficient number of cases. In the future, more patients will need to be studied.

Nociplastic pain by the "International Association for the Study of Pain" is defined as pain that arises from altered nociception despite no clear evidence of nociceptive or neuropathic pain. Augmented central nervous system pain and sensory processing with altered pain modulation are suggested to be the mechanism of nociplastic pain. Clinical criteria for possible nociplastic pain affecting somatic structures include chronic regional pain and evoked pain hypersensitivity including allodynia with after-sensation. In addition to possible nociplastic pain, clinical criteria for probable nociplastic pain are pain hypersensitivity in the region of pain to non-noxious stimuli and presence of comorbidity such as generalized symptoms with sleep disturbance, fatigue, or cognitive problems with hypersensitivity of special senses. Criteria for definitive nociplastic pain is not determined yet. Eight specific disorders related to central sensitization are suggested to be restless leg syndrome, chronic fatigue syndrome, fibromyalgia, temporomandibular disorder, migraine or tension headache, irritable bowel syndrome, multiple chemical sensitivities, and whiplash injury; non-specific emotional disorders related to central sensitization include anxiety or panic attack and depression. These central sensitization pain syndromes are overlapped to previous functional pain syndromes which are unlike organic pain syndromes and have emotional components. Therefore, nociplastic pain can be understood as chronic altered nociception related to central sensitization including both sensory components with nociceptive and/or neuropathic pain and emotional components. Nociplastic pain may be developed to explain unexplained chronic pain beyond tissue damage or pathology regardless of its origin from nociceptive, neuropathic, emotional, or mixed pain components.

The design of osteotomy plane in orthognathic surgery has been developed to diminish the nerve injury. Intraoral Vertico-Sagittal Ramus Osteotomy (IVSRO) is the one of the best way to minimize untoward results, which is designed not to expose the lingula. We evaluated the nerve damage before and after with current perception threshold (CPT) test which is modem and numerically expressible way of nerve damages. Sixty patients underwent IVSRO since 1998 were evaluated. They were divided into 2 groups; one group underwent IVSRO only, and the other underwent IVSRO plus genioplasty. The both groups were evaluated with CPT test 1 week before surgery, and 1, 3 and 6 months after surgery. The CPT test was performed on A-beta, A-delta and C fiber respectively. 111e result showed that the recovery of sensory function of damaged nerve fibers was observed at the period of three to six months after surgery. There was no impairment of nerve function after only the IVSRO . But there were sensory disturbances in cases of additional genioplasty group. We thought that one of major factors on nerve damages were exposure of nerve and traction injury during genioplasty.

Bcl2-associated athanogene 3 (BAG3) mutations have been reported to cause the myofibrillar myopathy (MFM) which shows progressive limb muscle weakness, respiratory failure, and cardiomyopathy. Myopathy patients with BAG3 mutation are very rare. We described a patient showing atypical phenotypes. We aimed to find the genetic cause of Korean patients with sensory motor polyneuropathy, myopathy and rigid spine. We performed whole exome sequencing (WES) with 423 patients with sensory motor polyneuropathy. We found BAG3 mutation in one patient with neuropathy, myopathy and rigid spine syndrome, and performed electrophysiological study, whole body MRI and muscle biopsy on the patient. A de novo heterozygous p.Pro209Leu (c.626C>T) mutation in BAG3 was identified in a female myopathy. She first noticed a gait disturbance and spinal rigidity at the age of 11, and serum creatine kinase levels were elevated ninefolds than normal. She showed an axonal sensory-motor polyneuropathy like Charcot-Marie-Tooth disease (CMT), myopathy, rigid spine and respiratory dysfunction; however, she did not show any cardiomyopathy, which is a common symptom in BAG3 mutation. Lower limb MRI and whole spine MRI showed bilateral symmetric fatty atrophy of muscles at the lower limb and paraspinal muscles. When we track traceable MRI 1 year later, the muscle damage progressed slowly. As far as our knowledge, this is the first Korean patient with BAG3 mutation. We described a BAG3 mutation patient with atypical phenotype of CMT and myopathy, and those are expected to broaden the clinical spectrum of the disease and help to diagnose it.

This study performs erection of a pendulum hanging at a free end of an arm by rotating the arm to the upright position. A mathematical model of a rotary inverted pendulum system (RIPS) is derived. A brain emotional learning based intelligent controller (BELBIC) is designed and used as a controller for swinging up and balancing the pendulum of the RIPS. In simulations performed in the study, a pendulum is initially inclined at $45^{\circ}$ with respect to the upright position. A simulation is also performed for evaluating the adaptiveness of the designed BELBIC in the case of system variation. In addition, a simulation is performed for evaluating the robustness of the designed BELBIC against a disturbance in the control input.

Carpal tunnel syndrome is a common peripheral nerve entrapment syndrome that is characterized by pain, numbness, sensory disturbance along the distribution of the median nerve in hand. Diagnosis mainly depends upon careful examination and symptomatology. Treatments have included wrist immobilization, anti-inflammatory drug, local injection of steroid, nerve block and surgical decompression. This is a clinical report about 2 cases of carpal tunnel syndrome patients who undergo oriental medical treatment. Both of two cases, Symptoms were disappeared and physical examinations were improved. The results of this study demonstrate that oriental medicine treatment that including acupuncture and herbal medicine therapy can have noticeable effects in treating the carpal tunnel syndrome.

The authors present a rare case of clear cell ependymoma that developed in the cauda equina. A 54-year-old man was admitted to hospital with intermittent lower back pain. A neurological examination conducted on admission revealed no sensory or motor disturbance. Deep tendon reflexes in both lower extremities were normal. Magnetic resonance images demonstrated a 1.0 cm-sized intradural mass at the filum terminale. Gross total resection was performed via total laminectomy of L1 and L2. The tumor was confirmed to be clear cell ependymoma by histopathologic examination. His symptom was relieved after surgery.
