ABSTRACT
Introduction: This study aimed to evaluate the etiology and prognosis in burn children and adolescents referred to Shahid Motahari Trauma and Burn hospital. Materials and Methods: This cross-sectional study was conducted on burn children and adolescents who were hospitalized in Shahid Motahari Burns Hospital between 2009 and 2019 due to burns. Results: In this study, 3,520 patients were studied; of which 2,151 subjects were boys (61.1%) and 1,369 subjects were girls (38.9%). The mean age of the subjects was 2.84 ± 3.66 years. 138 (3.9%) patients died in the study. The relationship between mortality and gender was not statistically significant (P value = 0.336). The highest percentage of burns was 10 to 19% in 1284 patients (36.63%) and the lowest was 80 to 89% burns in 7 patients (0.19%). In terms of burn site, the most areas related to the trunk, lower limbs except the legs and upper limbs except the hands with 22.56%, 18.95%, and 18.45%, respectively, and the lowest related to the legs and the whole body with 6.39% and 8.46%. Also, the highest cause of burning was boiling water in 1915 patients (56.12%). Conclusion: The study showed that boys were more likely to be the victim of burns. Also, the highest percentage of burns was less than 20% and most of the areas are related to the trunk, limbs. The mortality rate was 3.9%. In addition, these evaluations showed that the most common cause of burns was boiling water.
ABSTRACT
Aim: Although one-fourth of the pituitary tumors are inactive and silent, increased total volume of the pituitary gland exerts pressure on sella turcica and corrodes the clinoid processes, resulting in several problems. Therefore, determination of the prevalence of the concealed pituitary tumors is of major concern among clinical practitioners. This study was performed to determine the prevalence of these tumors in cadavers referred to the Iranian Legal Medicine Organization (Kahrizak, Tehran). Materials and Methods: This cross-sectional descriptive study was performed between June 2007 and February 2008. A total of 485 cadavers were selected by simple random sampling method. Pituitary glands were removed and then horizontally cut and four slides were prepared from each of them, stained by hematoxylin and eosin, and evaluated by a light microscope. For statistical analysis, SPSS software (version 16), Mann-Whitney U test, Kolmogorov-Smirnov nonparametric test (K-S test), and Chi-square test were used. Results: Of the 485 investigated cadavers, 365 (75.3%) were males with an average age of 42 ± 20.5 years and 120 (24.7%) were females with an average age of 44 ± 22 years. A total of 61 (12.6%) had concealed pituitary masses. No statistically significant difference was found between the mean age, sex, and body mass index (BMI) of the cadavers with and without concealed tumors (P=0.380 P=0.450, and P=0.884, respectively). Conclusions: In the present study, the prevalence of the concealed pituitary adenomas was 12.6%. There was no correlation between age, sex, and BMI and the prevalence of the concealed masses.
