Review[Prevention of traffic deaths in accidents involving motor vehicles].
A vehicle's speed and age determine the degree of injury inflected in traffic accidents. Drivers under the influence of alcohol have an increased risk of death in traffic accidents, and males have twice the risk of traffic death as women per kilometre driven. ⋯ Traffic deaths are a result of accident and damage factors, which inflect lethal injury especially on the elderly. This can be illustrated as: number of deaths = accidents * damage in accidents.

Based on previously published studies, this review describes the pulmonary consequences of marijuana smoking. Smoking of marijuana is significantly associated with chronic bronchitis (cough and phlegm), but it has not been firmly established whether it also leads to a reduction in lung function. Both epidemiological studies and case reports suggest that regular smokers of marijuana have a higher risk of developing malignancies in both the upper and lower airways. Smoking of marijuana contaminated with fungus spores has been reported to lead to pulmonary aspergillus infections in immunocompromised patients, and sharing of marijuana water pipes has been associated with transmission of tuberculosis.

[Circulation monitoring of critically ill patients with the Pulse Contour Cardiac Output system].
The Pulse Contour Cardiac Output (PiCCO) monitoring system measures cardiac output with high precision and accuracy. The system may replace the pulmonary artery catheter in most critically ill patients because the rate of serious complications may be lower. Whether the use of dynamic or static fluid monitoring by PiCCO will result in better outcomes should be assessed by studies using clinically relevant end points.

Case Reports[Nephrotoxicity after the use of intravenous X-ray contrast media in a type 2 diabetic being treated with metformin].
Contrast media may induce nephrotoxicity, particularly in elderly patients with pre-existing renal impairment. The concomitant use of metformin may lead to lactic acidosis due to metformin accumulation. ⋯ The man had had an intravenous urography to examine an increased plasma creatinine level, and metformin had not been discontinued. We report the case to remind doctors of this avoidable side effect.
