ABSTRACT
Objective To evaluate the underlying causes of death of the in - patients with type 2 diabetes in Peking Union Medical College Hospital. Methods A cohort of 247 known dead in - patients with type 2 diabetes(132 men and 115 women) was identified from 1991 ～ 2003 in Peking Union Medical College Hospital. Underlying causes of death were obtained from death certificates and were coded according to the International Classifecation of Diseases (ninth revision). Results In our study, carduvascular disease was the most com-mon underlying cause of death and 110 death cases were attributable to it, and 64 to neoplasms,36 to respiratory disease, 14 to digestive disease, 10 to diabetes - related diseases, 1 to traffic accident cause, 13 to other natural causes. Conclusion This study confirms the im-portance of carduvascular disease as the major cause of death in people with type 2 diabetes. The evidence of an early effect on mortality suggests that prevention , early diagnosis, and treatment should be improved.
ABSTRACT
OBJECTIVE: To describe the underlying causes, surgical results, and prognostic factors in thoracic stenosis causing myelopathy, retrospective analysis for 28 cases of thoracic stenosis with surgery was performed MATERIALS AND METHOD: Twenty-eight patients(male, 15; female, 13) who underwent decompressive surgery for thoracic stenosis between 1987 and 1997 were analyzed. The mean age was 49 and the mean follow-up was 30.6 months. Statistical analysis with SPSS(r) was performed. Chi-square test was used for the analysis of relationship between subjects and multivariate analysis with general linear model was used to find prognostic factors. RESULT: Degenerative spondylosis was the most common cause, and three cases were associated with systemic diseases. Decompressive laminectomy was done in 23 cases, anterior decompression in four cases, and combined decompression in one case. Ossification of ligamentum flavum was found in 18 cases, facet hypertrophy in 13, ossification of posterior longitudinal ligament in six, and ventral spur in four. Postoperatively, 16 patients improved functionally and 4 patients worsened. The group of which initial symptom duration was less than two years showed better result(p=0.003). The group with sufficient decompression and no additional proximal stenosis had better outcome(p=0.002, p=0.001). CONCLUSION: Chronic myelopathy caused by thoracic stenosis can be reversible with appropriate decompression.
