Procalcitonin (PCT) is a prohormone that has been used as a marker for the diagnosis of bacterial infections. The aim of this study was to survey PCT levels in patients with cirrhosis. Sixty-four patients with hepatic cirrhosis and 32 healthy blood donors were enrolled in this study. ⋯ Among other cirrhotic patients, positive PCT levels were 77% for hepatitis B, 70% for cancer and 53.3% for unknown groups respectively. Serum procalcitonin levels were significantly higher in cirrhotic patients with bacterial infection (2.65±1.11 ng/ml) than those without infection (0.59±0.16 ng/ml, P=0.0001). PCT assay in cirrhotic patients may help diagnosis of sepsis and reduce unnecessary antibiotic use.

Medication errors in an internal intensive care unit of a large teaching hospital: a direct observation study.
Medication errors account for about 78% of serious medical errors in intensive care unit (ICU). So far no study has been performed in Iran to evaluate all type of possible medication errors in ICU. Therefore the objective of this study was to reveal the frequency, type and consequences of all type of errors in an ICU of a large teaching hospital. ⋯ According to our results, the rate of errors is alarming and requires implementation of a serious solution. Since our system lacks a well-organize detection and reporting mechanism, there is no means for preventing errors in the first place. Hence, as the first step we must implement a system where errors are routinely detected and reported.

Randomized Controlled Trial Comparative StudyComparison of effects of ephedrine, lidocaine and ketamine with placebo on injection pain, hypotension and bradycardia due to propofol injection: a randomized placebo controlled clinical trial.
Propofol is a widely used anesthetic drug because of its minor complication and also its fast effect. One of most popular complication in using this drug is pain during injection that is more sever in new generation of its components (lipid-free microemulsion). Other complications of propofol are bradycardia and hypotension. ⋯ Our data shows that in pain management all tested drugs can decrease pain significantly comparing with placebo (P=0.017). In control of hemodynamic parameters ephedrine could efficiently control SBP, DBP, MAP at the time 1 min after intubation. Based on our study ephedrine can be an appropriate suggestion for control of both pain and hemodynamic changes induced by propofol, although because of inconsistent result in other studies it is recommended to design a systematic review to draw a broader view on this issue.

Randomized Controlled Trial Comparative StudyThe effect of ondansetron and meperedin on preventing shivering after off-pump coronary artery bypass graft.
One of the most common complications of operation and anesthesia is shivering. The purpose of this study was to compare the effectiveness of Ondanseton and Meperedine in preventing shivering after off-pump coronary artery bypass graft (OPCAB). In this double-blind randomized clinical trial, the sample consisted of 90 patients, who were candidates of CABG under general anesthesia. ⋯ Bradycardia was 3.3% in group (A) and 0.0 % in group (B). Other variables (myoclonus, seizure and rash) showed no statistically significant difference (P=0.353). According to the findings, it was demonstrated that ondansetron is more effective in preventing shivering after Off-pump CABG than meperedine.

Designing a model for trauma system management using public health approach: the case of Iran.
Trauma is a leading cause of death and disability around the world. Injuries are responsible for about six million deaths annually, of which ninety percent occur in developing countries. In Iran, injuries are the most common cause of death among age groups below fifty. ⋯ This model may be implemented in two phases: the exclusive phase, focusing on resource integration and the inclusive phase, which concentrates on system development. The model could facilitate the development of trauma system in Iran through pilot studies as the assurance phase of public health approach. Furthermore, the model can provide a practical framework for trauma system management at the international level.
