In addition to ventricular arrhythmias, various forms of supraventricular arrhythmias (SVA) and atrioventricular (AV) and intraventricular (IV) conduction disturbances occur also in acute myocardial infarction (AMI). In the setting of AMI, SVA may be caused by relevant atrial ischemia or infarction. SVA complicate the course especially that of inferior, posterior and lateral AMI, SVA occur frequently also in the right ventricular myocardial infarction and in pericarditis. ⋯ The major cause of death in these patients are heart failure cardiogenic shock and malignant ventricular arrthythmias due to larger AMI, significant reduction of left ventricular function and advanced coronary heart disease. Complex SVA as well as serious AV and IV conduction disturbances are usually considered as markers, but not as independent predictors for both increased hospital mortality and in some cases also for that of posthospital mortality. Their occurrence in AMI may help to identify the patients at great risk who require a very intensive treatment including aggressive management of extensive coronary heart disease. (Ref. 62.).

Randomized Controlled Trial Clinical TrialBarbados Low Dose Aspirin Study in Pregnancy (BLASP): a randomised trial for the prevention of pre-eclampsia and its complications.
To determine whether prophylactic, low dose controlled-release aspirin improves outcome for pregnant women and their babies in Barbados. ⋯ The results of this study in Barbados do not support the routine use of low dose aspirin for prevention of pre-eclampsia or its complications, confirming results of previous large trials in other settings.

The clinical spectrum of respiratory syncytial virus disease in The Gambia.
Respiratory syncytial virus (RSV) is a well-recognized cause of lower respiratory tract infections in early childhood in industrialized countries, but less is known about RSV infection in developing countries. ⋯ RSV is a significant cause of lower respiratory tract infection in young children in The Gambia, causing epidemics of bronchiolitis. It poses a significant burden on the health system, especially through the demand for supplementary oxygen. The clinical spectrum of RSV disease in The Gambia is similar to that seen in developed countries; concomitant bacterial infections are uncommon.

Genital human papillomavirus (HPV) infection is highly prevalent in sexually active young women. However, precise risk factors for HPV infection and its incidence and duration are not well known. ⋯ The incidence of HPV infection in sexually active young college women is high. The short duration of most HPV infections in these women suggests that the associated cervical dysplasia should be managed conservatively.

Randomized Controlled Trial Clinical Trial
Randomised controlled trial of clinical outcome after chest radiograph in ambulatory acute lower-respiratory infection in children.
When available, chest radiographs are used widely in acute lower-respiratory-tract infections in children. Their impact on clinical outcome is unknown. ⋯ Chest radiograph did not affect clinical outcome in outpatient children with acute lower-respiratory infection. This lack of effect is independent of clinicians' experience. There are no clinically identifiable subgroups of children within the WHO case definition of pneumonia who are likely to benefit from a chest radiograph. We conclude that routine use of chest radiography is not beneficial in ambulatory children aged over 2 months with acute lower-respiratory-tract infection.
