The aim of this study was to evaluate the injury pattern, morbidity, and mortality in pedestrians involved in train accidents. The study was performed in the Hacettepe University School of Medicine, Turkey. Hospital records of 41 cases who were hit by train between the period of 1985-97 were evaluated. ⋯ It is concluded that train-pedestrian injuries represent a different type of trauma. The mortality rate in suicide attempts is high. RTS lower than 11 and being hit by train are associated with high mortality.

We conducted a prospective study of 152 adult patients presenting to an emergency department with chest pain or symptoms suggestive of acute myocardial infarction (AMI) to evaluate the first electrocardiogram (ECG), creatine kinase (CK)-MB and Troponin-T Rapid Assay (TnT) alone or in combination with chest pain in the initial diagnosis of AMI. A provisional diagnosis was made after the history, physical examination and the first ECG reading. Blood specimens were taken for TnT, CK and CK-MB mass. ⋯ A combination of the first ECG, CK-MB mass and TnT had a negative predictive value (NPV) of 87.9% (95% CI, 80.0-95.8). The first ECG was the most sensitive test while the combination of chest pain, ECG, cardiac enzymes and TnT gave the best results in the initial diagnosis of AMI. If the first ECG, CK-MB mass and TnT are all negative, the probability of having an AMI is 12%.

Atrial fibrillation (AF) is the most common cardiac arrhythmia observed in the emergency room (ER). We propose a new classification of AF which is useful for the standardization of terms to be used for future clinical trials and for clinical management of this arrhythmia in the ER. We recognized three categories: (1) atrial fibrillation lasting less than 72 hours (AF < 72 h); (2) persistent atrial fibrillation and (3) permanent atrial fibrillation. ⋯ In persistent AF the systemic thrombo-embolism is a significant risk and therapeutic anticoagulation must be associated to pharmacological or electrical cardioversion even though transoesophageal echocardiography does not visualize thrombi or spontaneous echocontrast in the cardiac chambers. These treatments can reconvert the persistent AF to sinus rhythm, but, in the absence of treatment, or if treatment fails, the arrhythmia goes into the permanent category. In permanent AF ventricular rate control and anticoagulation, if suitable, are the first choice for stroke prevention.

Hereditary angioedema is a hereditary disorder transmitted as an autosomal dominant trait, characterized by reduced plasma concentration of C1 esterase inhibitor (type 1) or the presence of non functional C1 esterase inhibitor (type 2). We describe and discuss the case of a 35-year-old man who presented two unusual clinical manifestations of type 2 hereditary angioedema causing diverse emergency situations: acute abdomen and parasellar oedema.
