CO exposure in our patients was acute, accidental, and occurred during the winter months. Serious symptoms, such as syncope, occurred more often in patients having increased COHb levels, but normal COHb levels could not be used to rule out CO poisoning.

Amaç Öğrenciler okulda mevcut hastalıklarında kötüleşme veya kaza geçirme nedeni ile ilk yardıma gereksinim duyabilirler. Bu nedenle öğretmenlerin ilk yardım girişimlerini bilmesi ve uygulayabilmesi gereklidir. Bu çalışmanın amacı, öğretmen adayı olan eğitim fakültesi öğrencilerinin ilk yardım bilgi düzeyini ve verilen ilk yardım eğitiminin etkinliğini saptamaktır. Gereç ve Yöntem Bu çalışmaya, 88 Gazi Üniversitesi Eğitim Fakültesi (Ankara) öğrencisi katıldı. Öğrencilere üç aylık dönem içinde 20 saat ilk yardım eğitimi verildi. Eğitim öncesi ve sonrası 20 soruluk ilk yardım bilgileri içeren sınav ve ilk yardım eğitimi ile ilgili anket düzenlendi. Bulgular Bu öğrencilerden 54'ü (%61.4) son 5 yıl içinde ilk yardım eğitimi almıştı. Ön test not ortalaması 47.89±11.28, son test not ortalaması 75.28±12.62 idi ve aralarında istatistiksel anlamlı artış vardı (p<0.001). Temel yaşam desteği ile ilgili sorulara doğru yanıt verme oranı eğitim sonrası istatistiksel anlamlı olarak artış gösterdi. "Yeterli ilk yardım bilgisi ve becerisine sahip olduğunuzu düşünüyor musunuz?" sorusuna verilen "evet" yanıtı eğitim öncesi %7.0'den, eğitim sonrası %58.0'e artış gösterdi (p<0.001). Sonuç Eğitim fakültesi öğrencilerinin ilk yardım bilgilerinin yetersiz olduğu, öğretmen yetiştiren tüm okullarda ilk yardım eğitimi verilmesi ve öğretmenlerin de bilgilerini güncellemesinin gerekli olduğu düşünülmektedir.

Background/aim: Pneumonia is the most serious clinical presentation of COVID-19. This study aimed to determine the demographic, clinical, and laboratory findings that can properly predict COVID-19 pneumonia. Materials and methods:This study was conducted in the Gazi University hospital. All hospitalized patients with confirmed and suspected SARS-CoV-2 infection between 16 March 2020 and 30 April 2020 were analyzed retrospectively. COVID-19 patients were separated into two groups, pneumonia and nonpneumonia, and then compared to determine predicting factors for COVID-19 pneumonia. Variables that had a P-value of less than 0.20 and were not correlated with each other were included in the logistic regression model. Results:Of the 247 patients included in the study 58% were female, and the median age was 40. COVID-19 was confirmed in 70.9% of these patients. Among the confirmed COVID-19 cases, 21.4% had pneumonia. In the multivariate analysis male sex (P = 0.028), hypertension (P = 0.022), and shortness of breath on hospital admission (P = 0.025) were significant factors predicting COVID-19 pneumonia. Conclusion:Shortness of breath, male sex, and hypertension were significant for predicting COVID-19 pneumonia on admission. Patients with these factors should be evaluated more carefully for diagnostic procedures, such as thorax CT.

IntroductionDespite the high incidence of pulmonary embolism its diagnosis continues to be difficult, primarily because of the vagaries of symptoms and signs in presentation. Conversely, syncope is a relatively easy clinical symptom to detect, but has varied etiologies that lead to a documented cause in only 58% of syncopal events. Syncope as the presenting symptom of pulmonary embolism has proven to be a difficult clinical correlation to make.Case presentationWe present the case of a 26-year-old Caucasian man with pulmonary embolism induced-syncope and review the pathophysiology and diagnostic considerations.ConclusionsPulmonary embolism should be considered in the differential diagnosis of every syncopal event that presents at an emergency department.

We reviewed the charts of 25 patients who underwent powered intraosseous line insertion between July 1, 2008 and August 31, 2010 to determine its users, indications, procedural details, success rates, and complications. Intraosseous (IO) line was inserted in the anteromedial aspect of the proximal tibia in all patients. The first attempt was successful in 80%, and the median duration for insertion of the IO line was 4 hours. Extravasation was the most common complication. Ninety-six percent of the physicians had undergone prior training in IO insertion. Because of its high success and short procedure time, IO access should be the first alternative to failed vascular access in critically ill children. Training in IO should be extended to all who care for pediatric patients in inpatient as well as in prehospital and emergency department settings.
