Objectives: To evaluate the effects of intramedullar nailing of the tibia using a suprapatellar (SP) approach with respect to pain and function of the knee.
Oil reserves which are located around the world are declining day by day, so new alternative energy sources must be invented for engines of internal combustion and compression ignition, so biodiesel that is an alternative fuel source for diesel engines and it is a renewable energy resource. Biodiesel is a fuel made from vegetable oils, animals’ fats and waste oils. In this study, physical and chemical properties of biodiesel were analyzed and matched to the diesel fuel. In the experimental study, biodiesel was made from animal fats and compared to diesel fuel. Its effects on engine performance and emissions are studied. A single-cylinder, four-stroke, direct injected diesel engine with air cooling system are used as test equipment in different cycles. After the experimental study, it is concluded that the reduction of the emissions of CO and HC as biodiesel has the advantage of emission output. Environmentalist property of biodiesel is the most important characteristic of it. But the sight of engine performance diesel fuel has more advantage to biodiesel fuel
Objectives: This study aims to investigate the possible correlations between the heterotopic gastric mucosa (HGM) islets in the cervical esophagus and laryngopharyngeal reflux (LPR).
Patients and Methods:Between May 2010 and April 2011, 45 patients (36 females, 9 males; mean age 39.8±14.1 years; range 18 to 72 years) who had reflux symptom index (RSI) >10 and reflux finding score (RFS) >7 were included. The study group consisted of 21 patients who were diagnosed with HGM islets in the cervical esophagus, while control group consisted of 24 patients without any HGM islets assessed by upper gastrointestinal system endoscopy. Esophagus manometric examination and dual-channel 24-hour pH monitoring were performed on all patients.Results: Pretreatment mean RSI and RFS were 25.6±3.5 and 15.1±3.4 in group 1, while it was found to be 21.1±4.4 and 11.9±2.6 in group 2 (p=0.001, p=0.001). A total of 29.7% of patients who underwent pH monitoring had distal reflux, whereas 43.2% of them had proximal reflux. In group 1, distal reflux was observed in 15.4% and proximal reflux was found in 54% of the patients, while distal reflux was observed in 38% and proximal reflux was found in 38% of the patients in group 2 (p=0.152; p=0.27). Fourteen patients diagnosed with HGM had antral-and seven patients had fundal-type epithelium.
Conclusion:Our study results suggest that HGM islets may be considered as an etiological factor in the patients with severe LPR with isolated proximal reflux based on the 24-hour pH monitoring.
BACKGROUND: Coordination of an emergency response team is an important determinant of prompt treatment for combat injuries in hospitals. The authors hypothesized that instant messaging applications for smartphones could be appropriate tools for notifying emergency response team members. The objective of this study was to investigate the efficiency of a commercial instant messaging application (WhatsApp, Mountain View, CA) as a communication tool for the emergency team in a level-I trauma center.
Lymphomas are solid tumors that arise from lymphoid tissue and present themselves as Hodgkin's or non-Hodgkin's lymphoma. Particularly gastrointestinal lymphomas can be clinically confused with other gastrointestinal tumors as well as with diffuse and inflammatory bowel disease. Early diagnosis and treatment bear vital importance in the management of lymphomas due to their high proliferation rates. In this report, we are presenting a case which initially displayed clinical and radiological signs of Crohn's disease, but was eventually diagnosed as Burkitt's lymphoma by laparotomy, and also we aim to underscore the importance of differential diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
