five years survival for decompensated cryptogenic cirrhosis has been reported less than 14%. the patient is a 70 years old man who had cryptogenic cirrhosis since the last 22 years after splenectomy. he had episodes of upper gi bleeding and ascitis at least for the last 17 years. he is still alive and is doing his daily work appropriately.
background and objectives: gliomas are the most prevalent primary brain tumors. the purpose of this retrospective cohort study was evaluation of clinical trend and prognosis of patients with brain glioma and effective factors in prognosis. materials and methods: hundred and forty-five patients with supratentorial brain glioma, treated in shahid mostafa khomeini & hazrat-e-rasool hospitals i...
introduction: pulmonary embolism is one of the leading causes of mortality in patients.the mortality rate of this disease can be significantly reduced with appropriate treatment. surgical intervention can be highly effective for the treatment of acute massive pulmonary embolism. this article presents a report on the experience of acute pulmonary embolectomy. materials and methods: demographic d...
background pancreatic neuroendocrine tumors (pnets) are rare tumors with variable malignant potential, prognosis, and survival. we aimed to assess the characteristics of patients with non- functional pnet in our hospital . methods from nov 2010 to nov 2013 , all patients who came to endosonography unit of shariati hospital , tehran , iran , and had pancreatic lesions were assessed . tumor s...
In this paper, we propose a new parametric distribution which called as the Beta Modified Weibull Power Series (BMWPS) distribution. This distribution is obtained by compounding Beta Modified Weibull (BMW) and power series distributions. BMWPS distribution contains, as special sub-models, such as Beta Modified Weibull Poisson (BMWP) distribution, Beta Modified Weibull Geometric (BMWG) distribut...
Background: Cementless hip prosthesis was designed to provide biologic fixation, without the use of cement. The second generation components have shown more reliable bone ingrowths and survival rates. We are reporting a midterm result of two designs of cementless prosthesis in a unique culture with different social habits and expectations.Methods: 52 primary cementless total hip arthroplasty in...
Background: Identification of the factors influencing short term and long term survival for patients is one of the important concerns in medical society. With determining the risk factors and also health factors of a disease, valuable information can be obtained. In some cases, such as high rate of censoring, the use of standard survival models for analysis may cause to loss in some of...
Designing a Comparative Model of Bank Credit Risk Using Neural Network Models, Survival Probability Function and Support Vector Machine
in determining the physiological or physio-pathological function of oxygen reactive spices. Release of reactive oxygen species (ROS) in dermal wounds, leads to necrosis as well as apoptosis and tissue loss. Management of the risk factors for tissue loss due to flap failure can reduce risk factors with resultant improvement in the survival and efficacy of the flaps. Materials and Methods: 40 Spr...
Background: Access to a safe and efficient chemotherapy regimen for improving the survival and live quality is a goal in ovarian carcinoma. Despite surgery is the base treatment of ovarian cancer, but in most patients chemotherapy is used due to progression of their disease. This study designed to compare two important chemotherapy regimens. Methods: This historical cohort study compared two c...
