Adult spinal deformity is a complex condition, increasing in prevalence, and occurring in a patient population in which it poses unique challenges. This review provides an overview of adult spinal deformity with a particular focus on its clinical evaluation, radiological assessment and classification, reviewing the current literature and amalgamating this with the authors' clinical experience.

Typical hypnotic drugs, such as barbitals and glutethimide, have a cyclic imide (-CO-NH-CO-) moiety. The N-Cbz-alpha-aminoglutarimidooxy carboxylate derivatives, which we previously showed exhibit moderate anticonvulsant activities, also have a cyclic imide (-CO-N-CO-) moiety. This structural similarity prompted us to examine the hypnotic activities of the N-Cbz-alpha-aminoglutarimidooxy carboxylate derivatives, and we describe their moderate hypnotic activities here.

Purpose:The purpose of this study was to determine the significant factors for risk estimate of aspiration and to evaluate the efficiency of the dysphagia assessment tool. Methods: A consecutive series of 210 stroke patients with aspiration symptoms such as cough and dysphagia who had soft or regular diet without tube feeding were examined. The dysphagia assessment tool for aspiration was compared with videofluoroscopy using Classification and Regression Tree (CART) analysis. Results: In CART analysis, of 34 factors, the significant factors for estimating risk of aspiration were cough during swallowing, oral stasis, facial symmetry, salivary drooling, and cough after swallowing. The risk estimate error of the revised dysphagia assessment tool was 25.2%, equal to that of videofluoroscopy. Conclusion: The results indicate that the dysphagia assessment tool developed and examined in this study was potentially useful in the clinical field and the primary risk estimating factor was cough during swallowing. Oral stasis, facial symmetry, salivary drooling, cough after swallowing were other significant factors, and based on these results, the dysphagia assessment tool for aspiration was revised and complemented.
