[Survival rate in MI patients]

Today, heart diseases are the most common mortality causes in many of the world countries. According to current statistics, mortality rate from MI have been increased in Iran. The aim of this study was to determine survival rate and its effective cause in MI patients. This analytical-descriptive study was performed on 800 MI patients in Ardabil Bouali hospital. One year follow-up was carried out for all patients and data collected through a questionnaire. The reliability and validity of questionnaire had been earlier evaluated using Cronbach's alpha in 30 samples pilot study. Data analysis was carried out by statistical methods such as: Kaplan-Maier for survival rate and log-rank test for comparison survival mean in two groups using SPSS software. Cox regression model and survival graph was used for predictive effective causes on survival rate. Age mean of patients was. For one-year follow-up, mortality rate was 10.5% for all patients. 72.8% of patients were male and 27.2% female. 47.4% of patient was smoker, 33.4% have a HTN history, 18.1% were diabetic and 15.3% had high lipid. Survival rate in first ten days, first month and a year following MI was 0.95, 0.93 and 0.91, respectively. Effective causes in patient's survival rate were DM, HTN, SK and EF. Knowing survival rate and effective causes in MI patients, we can provide a better service as well as spatially works to control MI and decrease mortality rate from MI and also increase survival time in patients

[Evaluating the effectiveness of tendon transfer in birth palsy]

Results of tendon transfer in birth palsy have been evaluated in the USA and Europe, but there is no report on this type of treatment in Iran. The present study discusses the transferring of latissimus dorsi muscle for improvement of shoulder abduction. The results of tendon transfer were reviewed in patients with problems of shoulder abduction. They have been evaluated and followed up for about 6 months. Variation of their stage was calculated by sign test and the abduction range of shoulder were evaluated by paired-t test. 22 patients out of 33 cases were evaluated. The mean age was 5.4 +/- 3.2 years and 63.6% were females. Before operation 36% of patients were in stage 2 while 64% were in satge 3. After tendon transfer 73% patients were in stage 3 and 23% were in stage 4 [P<0/05]. The abduction angle of shoulder increased from 63.5 +/- 9.9 [before tendon transfer] upto 109.2 +/- 22.7 [after tendon transfer] [P<0/001]. As a surgical treatment for birth palsy, latissimus dorsi muscle transfer improved the abduction angle of shoulder with no considerable complications
