Review Meta AnalysisCentralisation of services for gynaecological cancer.
Gynaecological cancers are the second most common cancers among women. It has been suggested that centralised care improves outcomes but consensus is lacking. ⋯ We found low quality, but consistent evidence to suggest that women with gynaecological cancer who received treatment in specialised centres had longer survival than those managed elsewhere. The evidence was stronger for ovarian cancer than for other gynaecological cancers.Further studies of survival are needed, with more robust designs than retrospective observational studies. Research should also assess the quality of life associated with centralisation of gynaecological cancer care. Most of the available evidence addresses ovarian cancer in developed countries; future studies should be extended to other gynaecological cancers within different healthcare systems.

Chinese herbal medicines are commonly used to treat sore throat in China and are used worldwide by practitioners of traditional Chinese medicine (TCM). Their efficacy in treating sore throat has not previously been systematically reviewed. ⋯ Based on the existing evidence in this review, some Chinese herbal medicines for treating sore throat appeared efficacious. However, due to the lack of high quality clinical trials, the efficacy of Chinese herbal medicine for treating sore throat is controversial and questionable. Therefore we cannot recommend any kind of Chinese medical herbal formulation as an effective remedy for sore throat.

Review Meta AnalysisMedications for increasing milk supply in mothers expressing breastmilk for their preterm hospitalised infants.
Breastmilk remains the optimal form of enteral nutrition for term and preterm infants until up to six months postnatal age. Mothers of preterm infants who have not established suck feeds must express their breastmilk and often have difficulty in maintaining sufficient volume for their infants' needs (Donath 2008). In preterm infants, donor breastmilk reduced the occurrence of necrotising enterocolitis, when compared with formula feeds (McGuire 2003). Also, case-control studies have suggested that breastmilk is associated with an improvement in feeding tolerance, a reduction in significant gastrointestinal infective events (Beeby 1992) and a reduction in late-onset sepsis (Schanler 1999) when compared with formula feeds in preterm hospitalised infants. ⋯ Two studies with a total of 59 mothers suggest modest improvements in short-term EBM volumes when a medication is used after insufficient EBM occurs in mothers following preterm delivery. In both studies, the medication was commenced ≧14 days post delivery and following insufficient EBM supply with other lactation supports.Currently, no studies support prophylactic use of a galactagogue medication at any gestation. Use of any galactagogue medication has only been examined at more than 14 days post delivery and after full lactation support has been given. Further trials should examine larger groups of preterm mothers and consider breastfeeding outcomes over a longer period.

Caesarean section rates are progressively rising in many parts of the world. One suggested reason is increasing requests by women for caesarean section in the absence of clear medical indications, such as placenta praevia, HIV infection, contracted pelvis and, arguably, breech presentation or previous caesarean section. The reported benefits of planned caesarean section include greater safety for the baby, less pelvic floor trauma for the mother, avoidance of labour pain and convenience. The potential disadvantages, from observational studies, include increased risk of major morbidity or mortality for the mother, adverse psychological sequelae, and problems in subsequent pregnancies, including uterine scar rupture and a greater risk of stillbirth and neonatal morbidity. The differences in neonatal physiology following vaginal and caesarean births are thought to have implications for the infant, with caesarean section potentially increasing the risk of compromised health in both the short and the long term. An unbiased assessment of advantages and disadvantages would assist discussion of what has become a contentious issue in modern obstetrics. ⋯ There is no evidence from randomised controlled trials, upon which to base any practice recommendations regarding planned caesarean section for non-medical reasons at term. In the absence of trial data, there is an urgent need for a systematic review of observational studies and a synthesis of qualitative data to better assess the short- and long-term effects of caesarean section and vaginal birth.

ReviewWITHDRAWN: Interventions for treating posterior cruciate ligament injuries of the knee in adults.
Injuries of the posterior cruciate ligament (PCL) of the knee frequently occur in automobile accidents and sports injuries, although they are less frequent overall than injuries of the anterior cruciate ligament (ACL). Some patients show significant symptoms and subsequent articular deterioration, while others are essentially asymptomatic, maintaining habitual function. Management of PCL injuries remains controversial and prognosis can vary widely. Interventions extend from non-operative (conservative) procedures to reconstruction of the PCL, in the hope that the surgical procedure may have a positive effect in the reduction/prevention of future osteoarthritic changes in the knee. ⋯ Future research should include randomized controlled trials of acute isolated PCL injuries, or PCL injuries when combined with other ligament injuries of the knee, treated operatively and conservatively. Adequate numbers of patients and an objective methodology for patient evaluation must be used in future studies of these interventions to determine the long-term results.
