The purpose of this study was to identify the correlations between disease related factors and disturbance of daily living in patients with fibromyalgia. A descriptive survey study design was used. Data were collected from 45 out patients diagnosed of fibromyalgia according to the conditions by American College of Rheumatology in I-city. The mean score of tender points were 15.00, fatigue was 8.67, quality of sleep was 12.94 and depression was 23.70. They have struggled with fibromyalgia for 6 years on an average. Among patients, 42.2% had to discontinue their job/learning due to their disease, and experienced a disturbance of daily living for 41.79 days during last 3 months. There were significant positive correlations between disturbance of daily living and tender points, depression, between fatigue and depression, quality of sleep, between quality of sleep and depression. As a result, fibromyalgia patients suffered from various disease related factors and disturbance of daily living. Therefore, it can be suggested that the consideration of these related factors is important to develope intervention program for the better qualified life of the patients.

The pathophysiology and neural mechanism involved in Tourette's and chronic motor tic disorder are highly controversial. In order to investigate the functional abnormalities of brain. In Tourette's and chronic motor tic disorder, 42 children with Tourette's and chronic motor disorder underwent single photon emission computed tomography(SPECT) using Tc-99m-HM-PAO. The results are summarized as follows : 1) 31.0% (13/42) of this series revealed perfusion defect in cerebral cortex. 2) 4.8% (2/42) revealed perfusion defect in basal ganglia. 3) 4.8(2/42) revealed perfusion defect in thalamus. 4) 16.7%(7/42) showed perfusion defect in cerebellum. 5) The frequency of abnormal perfusion showed no significant difference between tic with and without attention deficit hyperactivity disorder. 6) The frequency of abnormal perfusion showed no significant difference between Tourette's and chronic motor tic disorder. These findings support the hypothesis of a possible involvement of brain dysfunction in the production of Tourette's and chronic motor tic disorder, and quantification of blood flow and co-registration with magnetic resonance imaging will increase the validity of this study.

Data were collected using structured questionnaires from June 23th to Oct. 08th, 2008 and analyzed using the SPSS 12.0 program. and it included descriptive statistics, t-test, $x^2$-test, Pearson correlation coefficient. Results: The mean quality of life score was 115.87, perceived health status was 4.40, pain was 6.31 and difficulty of daily activity was 77.62. On the demographic variables, age, living arrangement, level of economics showed significant difference for the quality of life and sex and age showed significant difference for the perceived health status, pain, difficulty of daily activity. On the disease-related variables, duration of disease, use of analgesic drug showed significant difference for the dependent variables. There was a significant positive correlation among the quality of life, perceived health status, significant negative correlation pain and difficulty of daily activity. Conclusions: These results suggested that nursing intervention program including pain reduction, enhancing the perceived health status, ADL abilities and quality of life were necessary for the osteoarthritis patients in island residents.

The purpose of this study was to provide practical support methods of the library education and cultural programs for people with physical disabilities through the qualitative investigation. To collect data, focus group and individual interviews were conducted. Fourteen people with physical disabilities and six parents were interviewed. From the qualitative analysis, three themes and thirteen subthemes were emerged: (1) cognition about library, (2) difficulties of using the library, (3) support methods for activating library use. Finally, discussions, implications and future directions of library education and cultural programs for people with physical disabilities were presented based on the results of the study. We expect that this research can serve as a basis for further effort to develop library education and cultural programs suited for the unique needs of people with physical disabilities.

The pathophysiology of developmental language disorder is a highly controversial matter. In order to investigate the neural mechanisms involved in developmental language disorders, the authors studied three dimensional regional cerebral blood flow(rCBF) using Tc-99mH-MPAO in 42 children with developmental language disorders. The results are summarized as follows : 1) 61.9% (26/42) of this series revealed decreased perfusion in SPECT. 2) Regions of hypoperfusion were seen in cerebral cortex(47.6%, 20/42), thalamus(33.3%, 14/42), basal ganglia(11.9%, 5/42) and cerebellum(7.1%, 3/42). This study suggests that developmental language disorder could be due to specific functional impairment of the local brain regions which could not detected by conventional investigations such as brain CT or EEG.

Objectives The purpose of this study was to examine the psychiatric characteristics of outpatients with tinnitus. Methods A total of 88 subjects were included in this study. According to Tinnitus Handicap Inventory (THI) scores, the subjects were classified into two group ; a mild tinnitus symptoms (mild-tinnitus) group and a severe tinnitus symptoms (severe-tinnitus) group. A questionnaire was used for an assessment of demographic characteristics, and the THI, the Visual Analogue Scale (VAS) about tinnitus, the Beck Depression Inventory (BDI), and the Beck Anxiety Inventory (BAI) are applied for evaluation of other clinical psychiatric characteristics. Results Higher THI scores were positively correlated with tinnitus course, the number of accompanying symptoms, and the VAS. BDI total scores, BDI factors, and BAI total scores were significantly higher in the severe-tinnitus group than in the mild-tinnitus group. Also suicidal ideation, interpersonal problems, sleep problems, occupational impairment, and fatigue were significantly higher in the severe-tinnitus group than in the mild-tinnitus group. Conclusions Tinnitus is a common disorder of hearing which is associated frequently with psychiatric problems. This study suggests that psychiatric interventions should be taken into consideration in the treatment of patients suffering from tinnitus.

The neural mechanisms involved in attention deficit hyperactivity disorder are largely unknown. In order to investigate the neuroanatomical lesions of attention deficit hyperactivity disorders and their relationships with psychopathology, Single Photon Emission Computed Tomography(SPECT) using HMPAO was performed in 46 ADHDS and Yale Children's Inventory(YCI), Conners Parent Questionaire and DSM-III-R Questionaire for Disruptive Behavior Disorder were used to assess the psychopathology of ADHDS The results are summarized as follows; 1) 30.4% (14/46) of this series revealed decreased perfusion In SPECT. 2) Regions of hypoperfusion were seen in cerebral cortex(17.4%, 8/46), thalamus(13.0%, 6/46), deep gray matter(8.7%, 4/46), basal ganglia(6.5%, 3/46) and cerebellum(2.2%, 1/ 46). 3) The mean scores of the total YCI revealed significant difference between the two groups(SPECT abnormal versus normal group), and among the subscales, hyperactivity, language and fine-motor subscales showed significant differences between the two groups. Although the relationship between the abnormal findings and specific symptom clusters of ADHDS remains unclear, we can suggest that these abnormal findings could be associated with ADHD, and based on these findings, the ADHDS can be subclassified into two groups. This study can be said to reinforce the current conception of heterogeneity of ADHD.

Bow hunter's syndrome is a rare disease that shows the symptoms of vertebrobasilar insufficiency resulting from a dynamic obstruction or stenosis of the vertebral arteries during neck movement. This paper reports a case of a 59-year-old male who visited the emergency room with diplopia, tinnitus, and gait disturbance. Magnetic resonance imaging and angiography revealed a multiple cerebellar infarct, total obstruction of the right vertebral artery, and dynamic obstruction of the left vertebral artery during neck extension. As the infarction worsened, a thrombectomy was done. Posterior decompression and fusion at C5-6 were performed for the left vertebral artery. The left vertebral arterial patency was confirmed by intraoperative and postoperative angiography. No recurrence of the symptoms was observed for six months after surgery. Physicians need to pay attention to the diagnosis of vertebrobasilar insufficiency caused by an obstruction of the vertebral arteries during neck extension in cervical instability patients.
