A 5-year-old Siamese cat was presented at the Veterinary Medical Teaching Hospital in Seoul National University with visual impairment. The cat was blind and its pupillary light reflexes were sluggish OU. While there were no remarkable findings in the anterior segment, generalized tapetal hyperreflectivity and retinal vascular attenuation were observed in the posterior segment of both eyes. Any historical significance and clinical symptoms suggestive of infection or inflammation were absent. All of the above findings strongly indicated a diagnosis of hereditary retinal degeneration in the cat. This clinical case report demonstrates the possibility of the presence of feline hereditary retinal degeneration in Korea. Awareness of the condition should be raised to prevent the spread of hereditary retinopathy in the Korean cat population.

This study examined the awareness levels of stroke warning symptoms and the related factors among residents in a province and this paper presents the evidence for education and promotion strategies. The study subjects were 585 adults living in a province. The demographic factors and awareness levels of stroke symptoms were surveyed through a telephone interview. In the survey, the most frequently recognized warning symptoms were 'sudden speech disturbance (84.6%)', and 'sudden weakness of one side (73.9%)'. On the other hand, 'sudden dizziness (67.0%)', 'sudden visual impairment (55.4%)' and 'sudden severe headache (51.3%)' were less recognized. In a multiple regression analysis, male, young age, no familial history of stroke, no acquaintance history of stroke, low educational level, no exposure to promotional literature were significantly related to a low awareness level of the stroke warning symptoms. Providing customized programs will be helpful for enhancing the efficiency of promotion and education to the population with a low awareness level of stroke symptoms.

The self-report measure is a useful tool for evaluating self-recognized disability and difficulty in daily living activities. Although many studies and clinics used the Neck Pain and Disability Scale (NPDS) for measuring neck pain and functional impairment, there has not been much adaptation of this for use with Korean patients. The purpose of this study was to establish the reliability and validity of NPDS among Korean neck pain patients. Fifty-five subjects (32 males, 23 females) with neck pain enrolled in this study. They completed standardized self-administered questionnaires. The NPDS measures pain intensity; its interference with vocational, emotional, recreational, social, and functional aspects of living; and the presence and extent of associated factors. Reliability was determined by the intraclass correlation coefficient (ICC) and Cronbach's alpha for internal consistency. Validity was examined by correlating the NPDS scores to the Visual Analog Scale (VAS) score. The test-retest reliability of the translated versions of the NPDS was good ICC (2,1)=.86 (95%CI .76~.92). Cronbach's alpha value for NPDS was found to be .93, and this was statistically significant (p<.05). The criterion-related validity coefficient was .79 (p<.Oll. We conclude that the Korean version of NPDS has been shown to be a reliable and valid instrument for the assessment of neck pain. Successful linguistic and cultural translation will admit appropriate cross-cultural comparison for clinical analysis. Therefore, this study can be expected to be used as an adequate evaluation scale for neck pain related studies and treatments.

Objective : The endocrine dysfunction after the operation for suprasellar arachnoid cysts is not rare. The careful operation to prevent structures can prevent this complication, but it is not enough and effective to prevent it. Authors present technical surgical considerations to prevent this complication with a review of our suprasellar arachnoid cyst patients who had postoperative endocrine dysfunction. Methods : From January 2002 to December 2009, eight patients who had suprasellar arachnoid cysts with visual impairment underwent surgery. The mean age was 57.1 years (range, 33-77). Preoperatively, their endocrine function was clinically normal, and laboratory hormonal levels were within normal ranges. Cyst fenestration was performed by craniotomy (n=6) or by a neuro-endoscopic procedure (n=2), and, simultaneously, along with a cyst wall biopsy. Results : The surgery was uneventful in all eight patients, and there were no neurological morbidities. However, in four patients, endocrine dysfunction occurred postoperatively. We compared these four patients (group A) to the other 4 patients without endocrine dysfunction (group B) with intraoperative findings and with the histopathological findings of the cyst wall biopsy. The group A patients had more abundant vasculature on the cystic wall than the group B patients according to both the intraoperative findings and the histopathological findings. Conclusion : When performing a surgical cyst wall fenestration, surgeons should try to minimize the destruction of the cystic wall vasculature and not to make the fenestration at a site that contains many vascular striae.

A corneal dermoid is a benign congenital mass usually affecting the lateral limbal region. A 3-month old male Shih Tzu dog with abnormal tissue on right cornea was referred to Veterinary Medical Teaching Hospital of Seoul National University. On ophthalmic examination, there was no evidence of visual impairment. Slit lamp biomicroscopy assessment revealed a mass, located in the inferior and temporal part of right cornea. The lesion was typically hemispheric and covered with pink skin. Superficial keratectomy was performed to remove the mass. On histopathological examination, the lesion was diagnosed as a corneal dermoid. Four months after operation, there had been no recurrence and hair regrowth.

The objective of this study was to assess oral health status such as prevalence of dental caries, gingivitis and other combined disorder, orofacial dysfunction in patients with cerebral palsy(CP), as well as the state of tooth brushing, possibility of dental treatment. Sixty-six subjects with CP aged 9 to 37 years were included in the study. Clinical caries status(DMFT index) and other data were evaluated and statistically analyzed using SPSS program (SPSS 17.0). The results were as follows: The DMFT index and prevalence of gingivitis of study subjects were 2.82(male), 3.33(female) and 89%, respectively. DMFT index classified into four groups according to age as follows: DMFT index were 1.14(ages 6-11), 1.40(ages 12-14), 2.16(ages 15-24), 4.15(ages 25-37). In addition to the physical disorder, speech difficulty(86%), epilepsy(35%) and visual impairment(14%) were associated and the epilepsy medication was the most common medication. And orofacial dysfunction such as the eating difficulties(79%), drooling(36%), swallowing disorder(30%), breathing difficulty(15%), bruxism(30%) and snoring(33%) was shown. Most people with cerebral palsy can't brush alone and didn't use oral care adjunctive supplies. Moreover, Fifty-nine percent of them were noncooperative to dental treatment.

Purpose: The purpose of this study was to understand levels of both mental health literacy of depression and intention of help-seeking, and then to identify the relationship of them in Korean older adults. Methods: Participants in this cross-sectional survey were 395 persons over 65 years old receiving customized home visiting health care services at Chungnam province. Data were collected through interviews by visiting nurses in 2011. Results: The proportion of participants with depression was 61.8% ($6.7{\pm}3.6$). 78.2% of subjects appeared to have help-seeking intention for solving depression. The proportions of participants with ability to recognize depression was 69.1%. Although the level about knowledge and belief in self-help interventions were varied according to questionnaires, subjects understood self-help intervention of smoking accurately (86.3%) and physical activity (85.5%). Ability to recognize depression, knowledge and belief about self-help managements, and opinion of medication for treatment among health literacy variables measured in this study were related to help-seeking intention. In addition, women, visual impairment, and lower depression scores were related to help-seeking intention. Conclusion: Results demonstrate that it is necessary to improve depression health literacy to manage effectively depression of vulnerable elderly in communities. These results could be used in developing mental health literacy programs.

Objectives : The purpose of this study was to investigate the relationship between masseter and cervical muscle activity and temporomandibular disorder in female office workers. Methods : Experimental group of 24 healthy subjects complained of temporomandibular joint related to computer use which lasted more than 3 months in the past year and was present in the past 7 days as well as on the day of test. Control group of 20 healthy subjects had no complaints of minimal discomfort on the day of test, and had no discomfort in the past 7 days. If they had reported discomfort in the past 12 months, it was of a short duration(<3 months) and resolved at least 3 months prior to participation. Outcomes were assessed by meridian-electromyography(MEMG), whole spin x-ray, mandibular function impairment questionnaire(MFIQ), neck disability index(NDI), visual analog scale(VAS), Beck depression inventory(BDI), stress reaction inventory(SRI) and Holmes & Rahe social readjustment rating scale(SRRS). Results : The contraction power of masseter muscle, upper trapezius, sternocleido-mastoid muscle and erector spinae by MEMG was significantly higher in the experimental group. The muscle fatigue of masseter muscle and sternodeido-mastoid muscle by MEMG was significantly higher in the experimental group. SRI was significantly higher in experimental group. There was no significant difference between two groups in the Jackson's angle, Cobb's method and cranio-cervical posture. Conclusions : The results suggest that temporomandibular disorder related mental stress but physical stress does not change cervical structure significantly.

Objective : Stereotactic psychosurgery is known as one of effective means of treating in some medically intractable psychiatric illness. However, it is unfamiliar and it's long-term clinical result has not reported in our country. The authors evaluated its long-term results of pscychosurgery and discussed its neuroanatomical basis. Methods : Since 1993, eight patients underwent stereotactic psychosurgery for medically intractable psychiatric illnesses. All were referred from psychiatrist of these disorders, one was aggressive behavior, five were obsessive-compulsive disorders(OCD), and two were depression with anxiety disorders. Bilateral amygdalotomy and subcaudate tractotomy were done for aggressive behavior, and limbic leukotomy was done for OCD and depression with anxiety. The results of OCD were evaluated with with YBOCS(Yale-Brown obsessive compulsive scale) and VAS (visual analogue scale), CGI(clinical global impairment) in OCD, and OAS(overt aggression scale), MMS, WAIS were checked for the evaluation of aggressive behavior. Hamilton depression scale(HAMD) was used for evaluation of depression. Ventriculography was used in the first five patients and MR-guided stereotaxy was used in recent three cases for localization of target. The lesions were made with radiofrequency lesion generator. Results : With long-term follow up(mean 45 months) in five OCDs, mean YBOCS declined from 34 to 3(n=5). All returned to previous social life. In OAS scores of aggressive behavior during six-year follow up, scores declined from 8 to 2 with clinical improvement. In two patients with depression with anxiety, HAMD declined from 28.5 to 16.5(n=2). There was no operative mortality and no significant morbidity except one case of mild transient urinary incontinence. Conclusion : With these long-term results, authors assumed that stereotactic psychosurgery could be one of safe and effective mtherapeutic methods in several medically intractable psychiatric illness.

Acanthamoeba castellanii has ubiquitous distribution and causes primary acanthamoebic keratitis (AK). AK is a common disease in contact lens wearers and results in permanent visual impairment or blindness. In this study, we observed the cytopathic effect, in vitro cytotoxicity, and secretion pattern of cytokines in human corneal epithelial cells (HCECs) induced by A. castellanii trophozoites and/or cysts. Morphological observation revealed that panked dendritic HCECs co-cultured with amoeba cysts had changed into round shape and gradually died. Such changes were more severe in co-culture with cyst than those of co-cultivation with trophozoites. In vitro cytotoxicity assay revealed the highest cytotoxicity to HCECs in the co-culture system with amoeba cysts. A. castellanii induced the expression of $IL-1{\alpha}$, IL-6, IL-8, and CXCL1 in HCECs. Secreted levels of $IL-1{\alpha}$, IL-6, and IL-8 in HCECs co-cultured with both trophozoites and cysts were increased at an early incubation time (3 and 6 hr). These results suggested that cytopathic changes and pro-inflammatory cytokines release of HCECs in response to A. castellanii, especially amoebic cysts, are an important mechanism for AK development.
