Cervical ectropion is considered as one of the most common types of chronic cervicitis in China. Topical treatments for cervical ectropion including microwave tissue coagulation, are widely used in many hospitals in China. Nowadays, the necessary intervention for inflammatory cervical ectopy is controversial. ⋯ There are no RCTs comparing microwave therapy with other treatments or no treatment in symptomatic women with cervical ectropion. Although microwave therapy improved the appearance of the cervix over both laser therapy and interferon-alpha suppository therapy it is not clear if there is any other benefit for women.

ReviewIndigenous healthcare worker involvement for Indigenous adults and children with asthma.
Asthma education is regarded as an important step in the management of asthma in national guidelines. Racial and socio-economic factors are associated with markers of asthma severity, including recurrent acute presentations to emergency health facilities. Worldwide, indigenous groups are disproportionately represented in the severe end of the asthma spectrum. Appropriate models of care are important in the successful delivery of services, and are likely contributors to improved outcomes for people with asthma. ⋯ The involvement of IHW in asthma programs targeted for their own ethnic group in one small trial was beneficial for some but not all asthma outcomes. Thus there is insufficient data to be confident that the involvement of IHW is beneficial in all settings. Nevertheless, given the complexity of health outcomes and culture as well as the importance of self-determination for indigenous peoples, the practice of including IHW in asthma education programs for indigenous children and adults with asthma is justified, but should be subject to further randomised controlled trials.

ReviewProgestogens versus oestrogens and progestogens for irregular uterine bleeding associated with anovulation.
Dysfunctional uterine bleeding (DUB) is excessively heavy, prolonged or frequent bleeding of uterine origin which is not due to pregnancy or to recognisable pelvic or systemic disease. Anovulation may be inferred from a number of observations but, in the normal clinical situation, anovulation is often assumed when a woman presents with heavy, prolonged or frequent bleeding, particularly in those who are at the extremes of reproductive life and in women known to have polycystic ovarian syndrome. Menstrual bleeding that is irregular or excessive is poorly tolerated by the majority of women. Changes in the length of the menstrual cycle generally imply disturbances of the hypothalamo-pituitary-ovarian (HPO) axis. In anovulatory DUB with acyclic (irregular) oestrogen production there will be no progesterone withdrawal from oestrogen primed endometrium and so cycles are irregular. Prolonged oestrogen stimulation may cause a build up of endometrium with erratic bleeding as it breaks down and is expelled. This is the rationale for using cyclical progestogens during the second half of the menstrual cycle, in order to provoke a regular withdrawal bleed. Continuous progestogen is intended to induce endometrial atrophy and hence to prevent oestrogen-stimulated endometrial proliferation. Progestogens, and oestrogens and progestogens in combination are already widely used in the management of irregular or excessive bleeding due to DUB but the regime, dose and type of progestogen used varies widely, with little consensus about the optimum treatment approach. ⋯ There is a paucity of randomised studies relating to the use of progestogens and of oestrogens and progestogens in combination in the treatment of irregular bleeding associated with anovulation. Further research is needed to establish the role of these treatments in the management of this common gynaecological problem.

ReviewProphylactic antibiotics to reduce morbidity and mortality in neonates with umbilical artery catheters.
Umbilical artery catheters are often used in unwell neonates. Infection related to the use of these catheters may cause significant morbidity and mortality. The use of prophylactic antibiotics has been advocated for all newborns with umbilical artery catheters in order to reduce the risk of colonisation and acquired infection. Countering this is the possibility that harm, such as the emergence of antibiotic resistant organisms, may outweigh benefit. ⋯ There is insufficient evidence from randomised trials to support or refute the use of prophylactic antibiotics when umbilical artery catheters are inserted in newborn infants, and no evidence to support or refute continuing antibiotics once initial cultures rule out infection in newborn infants with umbilical artery catheters.

ReviewWITHDRAWN: Institutional versus at-home long term care for functionally dependent older people.
An increasing number of functionally dependent older people require care and medical treatment. Increasingly governments are shifting resources into community care expecting both reduction in costs and improvement in the quality of care. However, it is difficult to establish the costs and benefits of institutional and the alternative at-home care. ⋯ There is insufficient evidence to estimate the likely benefits, harms and costs of institutional or at-home care for functionally dependent older people.
