Aneurysm of the internal carotid artery is a rare disease and is known to be associated with congenital arterial anomalies such as neurofibromatosis type I (NF-I). NF-I is an autosomal dominant neurocutaneous disorder characterized by a variety of manifestations that involve the central and peripheral nervous systems, skin, vascular system, and skeleton. In particular, the involvement of vascular abnormalities in NF-I is well known. Any vessel may be affected by this condition, although the renal artery is most frequently involved. The vascular abnormality can be occlusive or an aneurysmal degenerative change. Therefore, symptomatic presentations might assume an indolent pathophysiologic course such as hypertension, or manifest as a catastrophic event such as arterial rupture that could result in sudden death. We report a rare autopsy case of an aneurysmal rupture of the internal carotid artery in a woman with suspected NF-I, who collapsed in her home.

STATEMENT OF PROBLEM: Several prosthetic options are available for the restoration of multiple adjacent implants. A passively fitting prosthesis has been considered a prerequisite for the success and maintenance of osseointegration. Passivity is a particular concern with multiple implants because of documented inaccuracies in the casting and soldering process. One way to avoid this problem is to restore the implants individually, however, the restorations of individual adjacent impants requires careful adjustment of interproximal contacts. PURPOSE: The purpose of this study was to compare the stress distribution pattern and amount surrounding Bicon implants with individual crowns and splinted restorations. MATERIAL AND METHOD: A photoelastic model of a human partially edentulous left mandible with 3 Bicon implants(4*1 mm) was fabricated. For non-splinted restorations, individual crowns were fabricated on 3 abutments (4.0*6.5 mm, 0 degree, 2.0 mm post, Bicon Inc., Boston, USA) After the units were cemented, 4 levels of interproximal contact tightness were evaluated: open, ideal (8 micrometershim stock drags without tearing), medium(40 micrometer), and heavy(80 micrometer). Splinted 3-unit fixed partial dentures were fabricated and cemented to the model. Changes in stress distribution under simulated non-loaded and loaded conditions(7.5, 15, 30 lb) were analyzed with a circular polaricope. RESULTS: 1. Stresses were distributed around the entire body of fin in Bicon implants. 2. Splinted restorations were useful for distribution of stress around implants especially with higher loads. 3. By increasing the contact tightness between the individually restored three implants, the stress increased in the coronal portion of implants. CONCLUSIONS: Ideal adjustment of the contact tightness was important to reduce the stresses around individually restored Bicon implants.

OBJECTIVES: This study aimed to investigate North Korean refugees' knowledge of mental illnesses and treatments and analyze the factors affecting this knowledge. METHODS: Subjects were selected via a snowball sampling method, and the survey outcomes of 152 North Korean refugee participants were analyzed. The factors affecting knowledge of mental illnesses were analyzed via a regression analysis by constructing a multivariate model with mental illness knowledge score as the dependent variable. RESULTS: The North Korean refugees' mental illness scores ranged from 3 to 24 points, with an average score of 13.0. Regarding the factors that influence mental illness knowledge, the subjects with South Korean spouses and those who had spent more time in South Korea had higher knowledge scores. Furthermore, the subjects who considered the mental health of North Korean refugees to be a serious issue revealed lower knowledge scores than those who did not believe it was a serious issue. The subjects who visit psychiatric clinics showed higher knowledge scores than those who do not. The South Korean subjects who had at least a college education exhibited higher scores than did those without advanced education. The subjects who are satisfied with life in South Korea manifested a higher mental illness knowledge score than those who are not. CONCLUSIONS: This study is significant as being the first study to ever measure and evaluate the level of North Korean refugees' knowledge of mental illnesses. In addition, the evaluations of North Korean refugees' mental illness knowledge and influencing factors while residing in South Korea created basic data that formed the foundation of an effort to enhance mental health literacy and provide proper mental health services. The results of this study can be utilized to solve mental health problems that might frequently occur during the unification process of North and South Korea in the future.

PURPOSE: To evaluate the usefulness of CT features of appendiceal mucocele in the diagnosis and evaluation of complications. MATERIALS AND METHODS: We retrospectively reviewed CT findings and compared with operative findings in 7 cases of pathologically proven appendiceal mucocele. CT findings such as location and extent of the lesion, Issue density, thickness or calcification of the wall, presence of adjacent inflammatory infiltration, and visualization of normal vermiform appendix were analyzed. RESULTS: Appendiceal mucocele was found as homogeneous low density cystic mass adjacent to the cecum, which has no surrounding inflammatory infiltration except in one case of perforation and one case of intussusception. Mean CT number measured in 4 cases was 21 Hounsfield unit. Thin curvilinear calcifications were noted along the cystic wall in 2 cases. Normal vermiform appendix couldn't be demonstrated in all cases. CONCLUSION: Appendiceal mucocele is characterized by homogeneously low density and thin walled cystic tumor adjacent to cecum without surrounding inflammatory infiltration, and absence of normal vermiform appendix on CT. Therefore, CT is valuable in preventing operative complications of appendiceal mucocele.

Purpose: Myofascial syndrome is a chronic muscle pain caused by repetitive motions with stress-related muscle tension. This study aimed to investigate the validity and reliability of the evidence for diagnosing myofascial pain syndrome in trapezius muscle using a pressure algometer and surface electromyography. Methods: The experiments were performed using a total of 10 subjects, and the target locations were determined by means of a pressure algometer in the right upper trapezius muscle. The part with the lowest pain value as the trigger point and the part with the highest pain value as the non-pain trigger point were selected for measuring the locations. The median frequency and average frequency were measured in those locations with electromyography. To check the muscle fatigue, the upper trapezius muscle was moved up and down for 2 seconds at 5-second intervals in 30 seconds. The measured values were evaluated using the independent paired t-test and MannWhitney U-test. Results: The median frequency at the non-trigger point (13.7) was significantly higher than that at the trigger point (7.3). Furthermore, the mean frequency (14.7) at the non-trigger point was significantly higher than that at the trigger point (6.3). Conclusion The results showed the correlations between the trigger points of the muscle pain and frequency analysis of surface electromyography. Thus, this study may be possible to use as a diagnostic tool for myofascial pain syndrome.

Background: Th17 cytokines such as interleukin-17 and interleukin-22 are expressed in atopic dermatitis lesions. Previous studies have reported increased levels of interleukin-17A, -17E, and -17F in patients with atopic dermatitis.As interleukin-17A, -17E and -17F act through a common receptor composed of interleukin-17RA, it is speculated that interleukin-17RA gene (IL17RA) mutation could affect the clinical characteristics of atopic dermatitis. Objective: This study aimed to characterize the clinical features of atopic dermatitis according to the presence of an IL17RA mutation in patients with atopic dermatitis. Methods: We performed reverse blot hybridization assay to detect IL17RA mutations in Korean patients with atopic dermatitis. The clinical features of atopic dermatitis were compared between atopic dermatitis patients with and without IL17RA mutation. Results: Of 332 patients with atopic dermatitis, 27 (8.1%) were found to have IL17RA mutation compared to 8 of 245 controls without atopic diseases (3.27%), which was statistically significant. Furthermore, 272 of atopic dermatitis patients (81.9%) had extrinsic type atopic dermatitis and 60 (18.1%) had intrinsic type. All patients with IL17RA mutations had extrinsic type. In addition, atopic dermatitis with IL17RA mutation was associated with longer disease duration, more frequent keratosis pilaris, higher blood eosinophil count, higher serum total immunoglobulin E level, higher house dust mite allergen-specific immunoglobulin E levels, and more need for systemic treatment than that in patients without IL17RA mutation. Conclusion IL17RA mutation is associated with the more severe extrinsic type atopic dermatitis. So, it may predict the progress to severe atopic dermatitis.
