[Compliance of patients with chronic obstructive lung disease receiving oxygen therapy at home].
Twenty-nine patients with severe chronic obstructive pulmonary disease (COPD) on long-term oxygen therapy (LTOT) were prospectively studied for compliance with therapy. Seven patients (24%) used oxygen < 16 hours/day and their mean 24-hour pulse oximetry showed mild hypoxaemia. In addition, we found that eight patients (28%) were smokers. We suggest that the follow-up of these patients should focus on the daily duration of the use of oxygen and cessation of smoking to optimise the effect of this therapy.

This review should be cited as: Bricker L, Neilson JP. Routine ultrasound in late pregnancy (after 24 weeks gestation) (Cochrane Review). In: The Cochrane Library, Issue 3, 2000. Oxford: Update Software. A substantive amendment to this systematic review was last made on 01 October 1999. Cochrane reviews are regularly checked and updated if necessary. ⋯ Based on existing evidence, routine late pregnancy ultrasound in low risk or unselected populations does not confer benefit on mother or baby. There is a lack of data about the potential psychological effects of routine ultrasound in late pregnancy, and the effects on both short and long term neonatal and childhood outcome. Placental grading in the third trimester may be valuable, but whether reported results are reproducible remains to be seen, and future research of late pregnancy ultrasound should include evaluation of placental textural assessment.

[Tobacco smoking and risk of hip fracture in men and women. Results from the Hovedstadens Center for Prospective Population Studies].
In the present population-based cohort study, we prospectively determined the influence of current, previous, and cumulative smoking history on the risk of hip fracture in men and women and addressed the issue of possible gender difference in susceptibility to tobacco smoking. ⋯ Tobacco smoking is an independent risk factor for hip fracture in men and women, and there appears to be no gender differences in the smoking-related risk. Men who stopped smoking for more than five years had lower risk of hip fracture than men who currently smoked, whereas no such risk reduction was seen in female ex-smokers.

Review[Reporting of incidents. Experiences with medical registration systems].
Current incident reporting systems in Denmark are primarily focused on litigation. Epidemiological studies in the United States have shown that only 2.7% of adverse events that qualify for litigation are identified in such systems. Existing Danish reporting on adverse effects and complications is not exhaustive and often focused on new medicine/technologies and only a few specialties. ⋯ Risk managers and locally based systems could increase reporting through better possibilities for direct feedback, although local systems have difficulty in initiating major prophylactic actions. Foreign epidemiological studies have shown an adverse events incidence of 3-13%. However, more than half of the adverse events occur at such a low frequency that it is unlikely that isolated hospital systems can produce sufficient information for prophylactic action.
