Objectives : The aim of this study was to investigate the effect of musculoskeletal symptoms and job stress on the fatigability of 268 dental health care workers in Busan. Methods : A structured, self-administered questionnaire was given from Oct 1 through Oct 10, 2015. The collected data were analyzed with the SPSS 18.0 program. Results : The results were as follows. First, for musculoskeletal symptoms, job stress and fatigability, the highest scores were for low back pain (3.23), business stress (2.95) and physical fatigability (3.32), respectively. Second, physical fatigability increased with increasing myofascial pain syndrome, low back pain and business stress. Mental fatigability increased with increasing business stress, human relationships and social activities and decreasing age. Conclusions : Taking the above into consideration, this thesis suggests that there is definite influence from musculoskeletal symptoms and job stress factors on physical and mental fatigability.

측두하악관절장애는 저작근, 측두하악관절, 주변 구조물 또는 모두를 포함하는 다수의 임상문제를 포함하는 용어이다. 근막동통은 측두하악관절장애 중 저작근 장애의 한 종류로, 근막 발통점에 의해 발생하는 감각, 운동, 자율신경 증상이다. 측두하악관절장애와 근막동통의 원인에 대한 논쟁이 지속되어왔다. 특히 교합 원인은 오랫동안 논쟁의 핵심이었으며, 많은 노력에도 불구하고 교합원인에 대한 연구는 상반된 결과를 보였다. 이런 논쟁은 대부분이 측두하악관절장애 본연의 복잡성에서 기인하지만, 부적절하고 부적당한 연구설계, 선정기준, 연구방법 또한 중요한 역할을 한다. 최근에 교합분석시 시간과 상대적 힘이 측정가능한 컴퓨터 교합분석 기기인 T-Scan II가 소개되었다. 일부 저자들은 T-Scan II를 이용하여 이개시간 개념 및 연장된 구치부 이개시간과 근막통증의 연관성에 대하여 제안하였다. 그러나 T-Scan II를 이용한 기존의 연구들은 근막통증에 대한 정확한 진단 기준을 제시하지 못하였으며, 대조군과의 비교 부재 및 다른 많은 문제점을 가지고 있었기 때문에 신뢰할 만하지 못하다. 이번 연구의 목적은 컴퓨터 교합분석 기기인 T-Scan II을 이용하여 30명의 실험군을 선택하고 이를 38명의 대조군과 비교함으로써, 근막통증과 구치부 이개시간과의 연관성을 평가하는 것이다. 통계적으로 분석된 결과는 다음과 같다: 1. 반복 측정한 이개시간의 Cronbach ${\alpha}$ 계수는 0.92 였다. 2. 반복 측정한 이개시간 평가시 양측에서 실험군과 대조군 사이 유의성 있는 차이를 보이지 않았다. 3. 이개시간 평가시 좌측 우측 사이에 유의성 있는 차이를 보이지 않았다. 이상의 결과로부터 근막통증과 이개시간 사이에는 관련성이 없는 것으로 판단된다. 따라서 근막통증을 치료하기 위하여 이개시간을 줄이는 비가역적인 치료는 적절치 않다. 향후의 연구에 있어서, 여러 교합요소와 헬키모 지수 등을 이용하여 증상의 정량화를 고려한 보다 통제된 대규모 환자 집단에 대한 연구가 필요할 것으로 사료된다.

Multiple sclerosis is a degenerative disease prevalent in northern climates, and its cause is unknown. The histopathological lesion in multiple sclerosis is the sclerotic "plague", a discrete focus of myelin loss with maintenance of axon segments and glial proliferation. The plaques may be seen in widely different brain and spinal tissues. The common causes of low back pain are psychosomatic disorder, myofascial pain dysfunction syndrome and herniation of nucleus pulposus. Local anesthetics cross the blood-brain barrier and the signs of CNS toxicity appear at a level between 4.5 and $7.0\;{\mu}g/ml$. This is a case report of acute back pain care after mandibular block anesthesia for the surgical extraction of mandibular root rests in an old aged woman with multiple sclerosis.

Purpose: This epidemiologic research was carried out to investigate the degree and aspects of symptoms of patients suffered from TMD using RDC/TMD. Subjects and Methods: Subjects were the patients who had visited to SNUBH dental clinic from Jan. 2005 to Dec. 2005, and total 117 patients were included (M: 22, F:95). The signs and symptoms of physical, psychological and behavioral factors were retrospectively evaluated by questionnaires in the RDC/TMD. The patients were examined through clinical and radiological method, and diagnosed by same investigator. They were divided into 3 groups such as osteoarthritis group (group 1), internal deragnement (group 2), myofascial pain dysfunction syndrome group (MPDS, group 3). In addition, in patient with complex diagnosis they were divided into subgroups in detail (ex. group 1+group 2). In the questionnaire, several items were selected to calculate the graded pain score (grade $0{\sim}IV$), depression and vegetative symptoms, nonspecific physical symptoms(pain items included) and nonspecific physical symptoms(pain items excluded) in each group. Results: As a result of classification by diagnostic criteria of this study, the patients were distributed to 45% of group 1, 47% of group 2, 8% of group 3 in this study. In younger patients (under 25-year old, n=40), group 2 was occupied 57% (n=23) and group 1 was 35%, group 3 was 8%, while group 1 was occupied 75% in elderly-patients (over 40-year old, n=28) in present study (group 2: 21%, group 3: 4%). In the analysis of depression and vegetative symptoms, majority of patients in Group 2 were included in 'normal', and in Group 3 it appeared to have larger proportion of 'moderate' & 'severe' than others. According to nonspecific physical symptoms, there have been tendencies of higher ratio of 'severe' in patients with MPDS. In graded pain score, more than half (58%) of subjects were included in grade 0 and low disability (Grade I and II), and 27% were revealed high disability (grade III, IV).

Background: An independent medical examination (IME) is a critical process for awarding reparation for injury. However, conducting an IME in pain medicine is very difficult, not only because pain is a subjective symptom, but also because there are no proper objective methods to demonstrate it. This study was conducted to compare IME reports and the court decisions on the disability status of the patients. Methods: We analyzed 79 IME reports and 25 corresponding court decisions on the disability status of patients. The diagnoses, causal relationships between the patients' status and the trauma, McBride's degree of disability, the American Medical Association's impairment ratings, the estimated annual cost for future treatment, and the necessity of care-giving were compared and analyzed. Results: The diagnoses in the 79 cases were complex regional pain syndrome (CRPS) type I (58 cases), CRPS type II (7 cases), peripheral neuropathy (5 cases), myofascial pain syndrome (4 cases), herniated intervertebral disc (2 cases), and fibromyalgia (1 case). The types of accidents were road traffic accidents (50 cases), military injuries (14 cases), industrial accidents (11 cases), and others (4 cases). The IME reports and the court decisions stated considerably different McBride's degrees of disability (P = 0.014). However, there was no significant difference in the estimated cost for future treatment between the IME reports and the court decisions (P = 0.912). Conclusions: IME reports should be accurate, fair, and based on objective findings. Feedback on IMEs from the court decisions is helpful for reference use.

Background: Cervical radicular pain can arise fromvarious structures, including spinal nerves, discs, zygapophyseal joints, ligaments, and myofascial connective tissue. However, no adequate experiments have been found regarding methods for the microadhesiolysis of adhesional connective tissue around the zygapophyseal joints and nerves. The first objective of this study was to ascertain the effect of fluoroscopy guided interventional microadhesiolysis and nerve stimulation (FIMS) on chronic cervical radicular pain caused by zygapophyseal joint dysfunction. The second objective was to identify the duration of pain alleviation, as well as commonly occurring regions for zygapophyseal joint dysfunction. Methods: Twenty-eight patients were diagnosed with cervical radicular pain. The cervical zygapophyseal joints and adhesional structures around the cervical zygapophyseal joints were stimulated by adhesiolysis with a rounded needle; the procedure was performed once every second week. A visual analogue scale (VAS) for pain and neck range of motion (ROM) were used as indices for evaluating the degree of pain 1 and 3 months after completion of the procedures. A relief effect of FIMS was accepted when the VAS index decreased 50% compared with a previous VAS, and when there was absence of limitation of ROM. Results: Among the patients, 52% showed zygapophyseal joint dysfunction in C5-6, 38% in C4-5, 7% in C2-3, and 3% in C6-7. After performing FIMS, the VAS index decreased in most of the patients after 1 and 3 months (92.8% and 75%, respectively), and treatment frequency was $2.7{\pm}1.2$. There was no correlation between the number of FIMS procedures and the degree of VAS. Conclusions: FIMS is considered an effective modality in patients suffering from cervical radicular pain.

Hypopharyngeal perforation secondary to tracheal intubation is rare, but may result in severe airway complications that include retropharyngeal abscess, pneumothorax, pneumonia, mediastinitis and death. The most common site of hypopharyngeal perforation is the pyriform sinus and the region of the cricopharyngeus muscle. We report a 62-year old man with intubation-induced hypopharyngeal injury presenting as deep neck infection. The patient presented with dyspnea and pain on the neck. Neck CT scan identified fluid and air collection on the neck from the hyoid bone to the thoracic inlet level. Despite of delayed diagnosis, we successfully operated him by using strap muscle myofascial transposition flap. The patient was followed up for 3 months without any complications.

Purpose : This epidemiological research was conducted to investigate the relationship between the groups of TMD and the behavioral, psychological, and physical symptoms through RDC/TMD. Subjects and Methods : The subjects of this research were the 286 patients who had visited Seoul National University Bundang Hospital; their common chief complaint was temporomandibular discomfort. The mean age of the patients was 32.9 from 11 to 85, and the number of men and women was 67 and 219, respectively. The patients were examined through clinical and radiological methods and diagnosed by 1 investigator. They were divided into 3 groups: myogenous group (group 1), arthrogenous group (group 2), and combined group (group 3). The behavioral, psychological, and physical symptoms were evaluated through questionnaires on RDC/TMD. Specific items were selected to calculate the graded chronic pain (characteristic pain intensity, disability points), jaw disability, depression, and non-specific physical symptoms (pain items included/excluded) in the questionnaire. One-way ANOVA, Kruskal-Wallis test, and chi-square test were applied as statistical methods. Results : As a result of classifying temporomandibular disorder in this study, the patients were distributed as follows: 9.1% of group 1, 79.7% of group 2, and 11.2% of group 3. In the analysis of graded chronic pain (characteristic pain intensity, disability points), jaw disability, and non-specific physical symptoms (pain items included/excluded), group 3 had the highest score, and the difference was significant (p<0.001). Moreover, the depression score of group 3 was significantly higher than groups 1 and 2 (p<0.05). Note that that the second order of jaw disability score was group 2, on the other hand, those of the other groups were group 1. Conclusion : Myofascial pain could be assumed to be related closely to the behavioral, psychological, and physical symptoms except jaw disability compared to joint pain through RDC/TMD.
