Total knee arthroplasty (TKA) is associated with considerable postoperative pain which may be difficult to manage. This article describes advantages and disadvantages of the different analgesic techniques used for pain treatment after TKA, for example i.v. patient-controlled analgesia, epidural pain treatment, and peripheral nerve blocks (especially femoral and sciatic blocks). Randomised studies suggest that peripheral nerve blocks have the best effect and have fewest side effects. Intra-articular administration of analgesics is the most recently introduced technique.

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.
