ABSTRACT
Objective: To determine the indicators predicting the hospital mortality in pedestrian injured patients admitted to a level I trauma center in Southern Iran
Methods: This case control study was conducted in a Level-I trauma hospital in Shiraz. We selected all survived pedestrians who were admitted in the hospital with duration of admission more than 24 hours in one year from March 2016 to February 2017 as control group and compared with all non-survived pedestrian patients who expired in the hospital according to clinical from March 2012 to February 2017. Multiple logistic regression was performed to identify factors of hospital effect on pedestrian mortality and results expressed by Odds Ratios and their confidence intervals [CI] of 95%
Results: A total of 424 survived pedestrian injured patients were compare to 117 non-survived one. Their mean of survived and non-survived patients were 43.79]19.37 and 56.76]18.55 years respectively of which 361 [66.7%] and 180 [33.3%] were men and women, respectively. We found that the gender does not have any relation with hospital mortality [p=0.275]. Followed by, age is in relevance with mortality. Glasgow Coma Scale [GCS], Injury Severity Score [ISS], blood urea nitrogen [BUN], platelet [PLT], potassium [K] and hemoglobin [Hb] are significant factor which are associated with mortality. According to logistic analysis GCS 24 [p<0.001], thrombocytopenia <150,000 [p<0.001], and hypokalemia <3.5 [p=0.01] were independently associated with hospital mortality. Among them, GCS
Conclusion: The results suggest that GCS score, ISS, hemoglobin level, platelet count, BUN and potassium level might be independent factors associated with hospital mortality in pedestrian injured patients
ABSTRACT
Androgenetic alopecia is an extremely common disorder affecting both men and women. The incidence is generally considered to be greater in males than females, although some evidence suggests that the apparent differences in incidence may be a reflection of different expression in males and females. This genetically determined disorder is progressive through the gradual conversion of terminal hairs into indeterminate hairs and finally to vellus hairs. Patients have a reduction in the terminal-to-vellus hair ratio, normally at least 2:1. Following miniaturization of the follicles, fibrous tracts remain. Patients with this disorder usually have a typical distribution of hair loss. This is a cross sectional study that conducted in Isfahan health center in 2007-2008. Using simple random sampling, we selected 1800 women in urban health center areas for hair loss. We evaluated the type of hair loss by Ludwig classification. The data was collected through administration of a specifically designed questionnaire and was analyzed using SPSS software. The chi-square and student tests were used for data analysis. According to results of this study the of 1800 women, 712 [39.6%] had hair loss. Mean age of females who had hair loss was 50.4 +/- 13 years. Thyroid disorders, ferritin serum level and androgenic hormones may play role in hair loss and their existance should be assessed
