Diagnostic value of QRS and S wave variation in patients with suspicion of acute pulmonary embolism.
This study aimed to investigate the diagnostic value of QRS and S wave variation in patients admitted to the emergency department with suspicion of acute pulmonary embolism (APE). ⋯ The present study demonstrated that QRS and S wave variation could be useful electrocardiographic signs for the diagnosis of APE.

The aim of this study was to identify factors associated with absent hematuria in patients with symptomatic urinary stones. ⋯ In this large cohort of patients with renal colic, 6% had no microhematuria. Although some CT findings and elevated BUN were independently associated with hematuria absence, there was no difference in the demographics, time of presentation and degree and location of pain between the groups.

Observational Study
Temporal variations in dispatcher-assisted and bystander-initiated resuscitation efforts.
To investigate temporal variations in dispatcher-assisted and bystander-initiated resuscitation efforts and their association with survival after bystander-witnessed out-of-hospital cardiac arrests (OHCAs). ⋯ Dispatcher-assisted and bystander-initiated resuscitation efforts are low during night-time in OHCAs witnessed by non-family. A divisional alert system to recruit well-trained individuals is needed in order to improve the outcomes of night-time OHCAs witnessed by non-family bystanders.

Early and reliable prediction of neurological outcome remains a challenge for comatose survivors of cardiac arrest (CA). The purpose of this study was to evaluate the predictive ability of EEG, heart rate variability (HRV) features and the combination of them for outcome prognostication in CA model of rats. ⋯ Earlier post-resuscitation HRV provided prognostic information complementary to quantitative EEG in the CA model of rats. The combination of EEG and HRV features leads to improving performance of outcome prognostication compared to either EEG or HRV based features alone.

There are few clinical problem of spermatic vein thrombosis were reported. Spontaneous spermatic vein thrombosis is a particularly rare diseases which can lead to acute or chronic testicular pain and testicular swelling. We report a case in which ultrasonography (US) discovered hypoechoic mass of left spermatic vein and contrast-enhanced ultrasonography (CEUS) revealed thrombus formation of left spermatic vein in a patient who had underwent a continuous driving for eight hours twenty days ago.
