We evaluated the results of twelve total elbow arthroplasties that had been performed from Feb. 1986 to Mar. 1993 in ten patients. The duration of follow-up averaged three years two months(range, one year to seven years one month). There were six females and four males. Two females had bilateral procedures. The average age at the time of the operation was 35.3 years(range, 22 to 53). Five patients had severe rheumatoid arthritis, four patients had fracture sequelae around elbows and one patient had sequele of tuberculous arthritis. Total elbow arthroplasty had been performed for improving the range of motion and relief of pain. Total elbow arthroplasties had been performed in six cases of total ankylotic elbows and in six cases who complained severe painful limitation of motion of the elbow joints. Preoperatively, ankylotic group were fixed by 30 degrees of flexion on an average. In painful elbow group, the average total range of motion was 68 degrees. The prosthesis which were used in total elbow arthroplasties were semiconstrained type in nine cases and noncostrained in three cases. Most of the patients had relief of pain. Postoperative complications were permanent ulnar nerve palsy in one case, superficial infection in one case and dislocation in one case. Total gain of range of motion(ROM) was 17 degrees in painful elbow group and 102 degrees in ankylotic elbows. Total elbow arthroplasty was effective method for improvement of range of motion in ankylotic elbows and relief of pain in elbows which had painful limitation of motion.

Both death certificates and postmortem examination certificates are used as proof of death. These certificates sometimes contain erroneous information but how frequently they do so is unknown. In particular, only a few studies have measured the accuracy of the cause and manner of death on Korea death documents. In this study, we compared the cause and manner of death on both kinds of certificates with those on autopsy reports to determine the frequency of errors, and to identify way to improve the accuracy of these certificates. In 2012, 528 autopsies were requested of out institute, and certificates were submitted in 241 of the cases. The manner of death was classified as natural, unnatural, or unknown. The cause of death in the autopsy report matched that on the death certificate in 37 of 63 cases (58.7%), and the manner of death matched in 40 of 63 cases (63.5%). The cause of death in the autopsy report matched that on the postmortem examination certificate in 62 of 178 cases (34.8%), and the manner of death matched in 74 of 178 cases (41.6%). Death certificates and postmortem examination certificates are important documents. We identified many incorrect reports of causes and manners of death on both kinds of documents, especially the postmortem death certificates. These inaccuracies are presumably due to a lack of forensic information and education, as well as lack of interest on the part of medical doctors.

This study was performed to evaluate the titer of serum acetylcholine receptor antibody (AChR-Ab), the correlation between AChR-Ab titer and clinical state, clinical response to thymectomy and histopathologic finding of thymus in myasthenia gravis. Twenty-seven patients with various clinical grades of myasthenia gravis and twenty-three norrnal controls were included in this study. Mean AChR-Ab titers were 4.21+4.27nM in myasthenia gravis and 0.05+0.06nM in control group(p<0.05). Mean AChR-Ab titers of each clinical grade were 0.80+1.67nM in grade I, 5.05+3.42nN in grade Iia, 8.37+4.50nM in grade Iib, 6.67nM in grade m and 10.89nM in grade IV. There were significant correlation between clinical grade and level of AChR-AB titer. There were no correlation between degree of clinical improvement and changes of serum AChR-Ab titer after thymectomy in myasthenia gravis. There were also no correlation between level of AChR-Ab titers and histopathologic findings of thymus.
