Abstract

Background: It can be used different models such as nonparametric, semi-parametric and parametric to estimation of survival. Depending on the nature of the data, some methods may be more appropriate. Using of appropriate model result more accuracy estimation of survival and it's affected. so the aim of this study estimation of survival and determination of its related risk factor. Materials and Methods: In this study, 169 patients with colorectal cancer who had treated in Hamadan MRI Center from March 2005 to Jun 2013 were evaluated. Survival time of patients is considered from diagnosis time to death or end of study. The effect of Demographic and clinical risk factors on survival is assessed by parametric model. follow up of patient Data were analyzed using Spss16 and R statistical software.

Results: The median survival was 4.3±40 months. Univariate analysis showed that the effect of staging of tumor, tumor grade, histology type of tumor, metastasis and relapse on survival were significant but in multivariate model histology type of tumor and metastasis were significant.

Conclusion: using of appropriate statistical model for detection of affected risk factor on patient with colorectal cancer can be prevented progression of disease and increased of survival of them.

Abstract

The surgical extraction of third molars is the most frequent surgical procedure in oral surgery. Subcutaneous emphysema is an uncommon clinical condition caused by forceful injection of air into the loose connective tissue below the dermal layer, and mostly is the result of using a high-speed air-driven hand piece during surgical tooth extraction. Subcutaneous emphysema is seen mostly in the third and fifth decade of life and in the right mandibular wisdom tooth extraction surgery site. Emphysema can spread to deep spaces such as infratemporal, pterygomandibular, masseteric, lateral or retropharyngeal or mediastinum. This study presents a case report of subcutaneous emphysema occurred during the third molar extraction by using an air-driven hand piece in a 28-year-old female patient. This study has no specific ethical considerations. Informed consent was obtained from the patient to use her information and images. Case management and the issues relative to the diagnosis and prevention of this surgical complication are discussed. Trismus was present with maximum opening of about 30 mm, and no signs of dysphagia and dyspnea were reported. Patient was administered 4 million units of penicillin Intravenous (IV) every 4 hours, metronidazole 500 mg IV every 8 hours solved in 100-cc normal saline infused slowly, and rinsing mouth with 0.2% chlorhexidine every 8 hours. The patient was hospitalized for 36 hours and treated with antibiotic regimen, and then followed up for day 5 until complete resolution of swelling, maximum opening up to 50 mm, and lack of crepitation. No other local, systemic and infectious complications occurred.
