우리 사회의 고령화가 지속됨에 따라 퇴행성 척추 질환을 가진 고령 인구가 증가하고 있다. 노인성 척추 질환은 일상생활을 불가능하게 하며, 경제활동을 어렵게 하여 결과적으로는 고령자 삶의 질을 훼손시킨다. 또한, 이 질환은 개별 환자에 최적화된 척추의 수술 및 재활 치료 방법이 요구된다. 그래서 본 논문에서는 노인성 척추 질환에 대한 효과적 대응을 위해 IT 기반의 경제적/과학적 해결 방안을 제시하는 "노인성 척추 질환 치료/재활을 위한 노령 인체 모델 및 의료기기 제품화 기반 기술"에 대해 소개한다.

Study Design: Retrospective radiographic study. Objective: To evaluate the characteristics of concurrent degenerative cervical and lumbar spondylolisthesis. Summary of Literature Review: Concurrent degenerative cervical and lumbar spondylotic diseases have been reported. Given that severe spondylosis can result in spondylolisthesis, one might expect that concurrent spondylolisthesis of the cervical and lumbar spines might also be prevalent. However, the incidence of spondylolistheses in the lumbar and cervical spines might differ due to anatomical differences between the 2 areas. Nonetheless, there is minimal information in the literature concerning the incidence of concurrent cervical and lumbar spondylolisthesis. Material and Methods: We evaluated standing cervical and lumbar lateral radiographs of 2510 patients with spondylosis. Concurrence, age group, gender, and direction of spondylolisthesis were evaluated. Lumbar spondylolisthesis was defined as at least Meyerding grade I and degenerative cervical spondylolisthesis was defined as over 2 mm of displacement on standing lateral radiographs. Results: Lumbar spondylolisthesis was found in 125 patients (5.0%) and cervical spondylolisthesis was found in 193 patients (7.7%). Seventeen patients had both degenerative cervical and lumbar spondylolistheses (0.7%). Lumbar spondylolisthesis is a risk factor for coexisting cervical spondylolisthesis. Lumbar spondylolisthesis was more common in females than males, independent of advancing age. In contrast, degenerative cervical spondylolisthesis was more common in older patients, independent of gender. Anterolisthesis was more common in the lumbar spine. Retrolisthesis was more common in the cervical spine. Conclusions: There was a higher prevalence of degenerative cervical spondylolisthesis in patients with degenerative lumbar spondylolisthesis.

Facet joint arthrosis is a progressive degenerative disease that is frequently associated with other spinal degenerative disorders such as degenerative disc disease or spinal stenosis. Lumbar facet joint arthrosis can induce pain in the proximal lower extremities. However, symptoms and imaging findings of "facet joint syndrome" are not specific as they mimic the pain from herniated discs or nerve root compression. Currently, evidence for therapeutic intra-articular lumbar facet joint injections is still considered low, with a weak recommendation strength. Nevertheless, some studies have reported therapeutic effectiveness of facet joint injections. Moreover, the use of therapeutic facet joint injections in clinical practice has increased. This review article includes opinions based on the authors' experience with facet joint injections. This review primarily aimed to investigate the efficacy of lumbar facet joint injections and consider their associated safety aspects.

노인성 난청(presbycusis)은 나이가 들어감에 따라 청력이 점진적으로 악화되는 것으로 성인 난청의 가장 흔한 원인중 하나이다. 미국과 마찬가지로 국내의 여러 연구에서 보면, 65세 이상의 노인 중 보청기를 착용해야 할 정도의 난청이 있는 비율이 전체의 30~35% 정도를 차지하고 있다. 이렇기 때문에 노인성 난청은 노인성 만성 질환 중 퇴행성 관절염, 고혈압에 이어 3대 만성 질환으로 분류되고 있다.

비만은 고혈압, 제2형 당뇨병, 지방간, 고지혈증, 퇴행성관절염, 일부 암성 질환 등 다양한 만성 퇴행성 질환들을 유발할 수 있으므로 비만을 하나의 질환으로 인식하고 치료할 필요가 있다. 비만은 식사요법, 운동요법과 행동수정요법을 병행해야 최상의 치료효과를 거둘 수 있다고 알려져 왔지만, 비만 치료가 끝나고 4년 후에 빠진 체중의 절반만이라도 다시 늘지 않고 유지하고 있는 사람은 10-30%에 불과하다. 그러나 비만 문제가 중요하고 현재까지의 치료방법이 성공적이지 못함에도 불구하고 비만의 약물 치료의 적절성에 대해서는 논란이 있다. 그러나 최근 비만의 약물 치료에 대해 재평가가 이루어지고 있으며, 식사, 운동, 행동요법과 약물치료의 병합 요법이 효과가 있음을 입증하는 연구결과들이 보고되고 있다. 여기에서는 비만증의 진단기준과 치료원칙을 간단히 설명하고 비만증의 약물요법을 위주로 살펴보도록 하겠다.

Feature ranking is useful to gain knowledge of data and identify relevant features. In this study, we proposed a use of feature ranking for classification of neuro-degeneration and vascular dementia in micro-Raman spectra of platelet. The entire region of the spectrum is divided into local region including several peaks, followed by Gaussian curve fitting method in the region to be modeled. Local minima select from the subregion and then remove the background based on the position by using interpolation method. After preprocessing steps, significant features were selected by feature ranking method to improve the classification accuracy and the computational complexity of classification system. PCA (principal component analysis) transform the selected features and the overall features that is used classification with the number of principal components. These were classified as MAP (maximum a posteriori) and it compared with classification result using overall features. In all experiments, the computational complexity of the classification system was remarkably reduced and the classification accuracy was partially increased. Particularly, the proposed method increased the classification accuracy in the experiment classifying the Parkinson's disease and normal with the average 1.7 %. From the result, it confirmed that proposed method could be efficiently used in the classification system of the neuro-degenerative disease and vascular dementia of platelet.

Degenerative brain diseases including Alzheimer's diseases, Parkinson's diseases increase in frequency with age. They are amongst the most costly and devastating diseases to patients and their families. Therefore developing therapies for degenerative brain diseases is of the highest priority. Recently therapeutics for these diseases have undergone scrutiny by many clinical trials according to the advances of cellular and molecular neurobiology. This review is focused on studies investigating the current therapeutic strategies already undergone different stage of clinical trials and recent R&D trend by nations through patent analysis on treatments for degegerative brain diseases.

퇴행성 질환으로 찾아오는 어깨 통증. 이러다 말겠지 했는데, 시간이 지날수록 극심한 통증이 끊이지 않는다. 대부분 오십견이라고 자가진단 하는데, 비슷한 증상을 보이지만 오십견일 수도, 회전근개손상일 수도 있다.
