This paper reports on a systematic review of qualitative research about vaginal practices in sub-Saharan Africa, which used meta-ethnographic methods to understand their origins, their meanings for the women who use them, and how they have evolved in time and place. We included published documents which were based on qualitative methods of data collection and analysis and contained information on vaginal practices. After screening, 16 texts were included which dated from 1951 to 2008. We found that practices evolve and adapt to present circumstances and that they remain an important source of power for women to negotiate challenges that they face. Recent evidence suggests that some practices may increase a woman's susceptibility to HIV and other sexually transmitted infections. The success of new female-controlled prevention technologies, such as microbicides, might be determined by whether they can and will be used by women in the course of their daily life.

There is poor agreement on definitions of different phenotypes of preschool wheezing disorders. The present Task Force proposes to use the terms episodic (viral) wheeze to describe children who wheeze intermittently and are well between episodes, and multiple-trigger wheeze for children who wheeze both during and outside discrete episodes. Investigations are only needed when in doubt about the diagnosis. Based on the limited evidence available, inhaled short-acting beta(2)-agonists by metered-dose inhaler/spacer combination are recommended for symptomatic relief. Educating parents regarding causative factors and treatment is useful. Exposure to tobacco smoke should be avoided; allergen avoidance may be considered when sensitisation has been established. Maintenance treatment with inhaled corticosteroids is recommended for multiple-trigger wheeze; benefits are often small. Montelukast is recommended for the treatment of episodic (viral) wheeze and can be started when symptoms of a viral cold develop. Given the large overlap in phenotypes, and the fact that patients can move from one phenotype to another, inhaled corticosteroids and montelukast may be considered on a trial basis in almost any preschool child with recurrent wheeze, but should be discontinued if there is no clear clinical benefit. Large well-designed randomised controlled trials with clear descriptions of patients are needed to improve the present recommendations on the treatment of these common syndromes.
