The Level of Knowledge and Opinions of Science Teacher Candidates on Safety Measurements in General Chemistry Laboratory Studies

In general chemistry laboratories of universities, faculty members and students work with chemicals and devices and they are exposed to various risks. For this reason, it is of great importance whether teacher candidates are who are the teachers of future are adequately equipped in terms of laboratory safety or not. This study was conducted on teacher candidates who participated in General Chemistry Laboratory practices in Science Teacher Education program and their opinions and knowledge levels about laboratory safety were investigated. In the study, teacher candidates were informed about the necessary precautions while working in a general chemistry laboratory in 4 courses. Then, in order to increase the awareness and responsibility of the students via the information that taught in courses, the General Chemistry Laboratory Safety questionnaire form given in the appendix was applied. The questionnaire form developed for laboratory safety was applied to 81 teacher candidates. According to the results obtained from the study, it has been found out that teacher candidates mostly find the general chemistry laboratory safety important and understand the importance of information about safety. SPSS 13.0 was used to analyze the consequences of the survey

Incidence, hospital costs and in-hospital mortality rates of surgically treated patients with traumatic cranial epidural hematoma

Background: In this study, the patients who were operated in two clinics due to traumatic cranial epidural hematoma (EDH) were assessed retrospectively and the factors that increase the costs were tried to be revealed through conducting cost analyses.Methods: The patients who were operated between 2010 and 2016 with the diagnosis of EDH were assessed in terms of age, sex, trauma etiology, Glasgow coma scale (GCS) at admission, the period from trauma to hospital arrival, trauma-related injury in other organs, the localization of hematoma, the size of hematoma, length of stay in the intensive care unit (ICU), length of antibiotherapy administration, number of consultations conducted, total cost of in-hospital treatments of the patients and prognosis.Results: Distribution of GCS were, between 13-15 in 18 (36%) patients, 9-13 in 23 (46%) patients and 3-8 in 9 (18%) patients. The reasons for emergency department admissions were fall from high in 29 (58%) patients, assault in 11 (22%) patients and motor vehicle accident in 10 (20%) patients. The average cost per ICU stay was 2838 $(range=343-20571$). The average cost per surgical treatment was 314 $. ICU care was approximately 9 times more expensive than surgical treatment costs. The mortality rate of the study cohort was 14% (7 patients).Conclusion: The prolonged period of stay in the ICU, antibiotherapy and repeat head CTs increase the costs for patients who are surgically treated for EDH

Spinal paragangliomas Surgical treatment and follow-up outcomes in eight cases

Paragangliomas are neuro-endocrine tumors originating from the adrenal gland. They are usually benign and nonfunctioning, rarely seen in central nervous system. More than 90% of central nervous system paragangliomas are manifested as carotid and glomus jugulare tumors. Spinal paragangliomas are quite rare
