In many settings, symphysis-fundal height measurement has replaced clinical assessment of fetal size by abdominal palpation because the latter has been reported to perform poorly. ⋯ There is not enough evidence to evaluate the use of symphysis-fundal height measurements during antenatal care.

ReviewEarly administration of inhaled corticosteroids for preventing chronic lung disease in ventilated very low birth weight preterm neonates.
Chronic lung disease remains a common complication amongst preterm infants. There is increasing evidence that inflammation play an important role in the pathogenesis of CLD. Due to their strong anti-inflammatory properties corticosteroids is an attractive intervention strategy. However, there are growing concerns regarding short and long term effects of systemic corticosteroids. Theoretically, administration of inhaled corticosteroids may allow for beneficial effects on the pulmonary system with a lower risk of undesirable systemic side effects. ⋯ There is no evidence from the trials reviewed that early administration (in the first 2 weeks of life) of inhaled steroids to ventilated preterm neonates was effective in reducing the incidence of CLD. There was a reduction in the need for systemic steroids. Although this difference was statistically significant, there was significant heterogeneity between studies and the upper limit of the 95% CI for this outcome was very close to no effect. Currently, use of inhaled steroids in this population cannot be recommended. Studies are needed to identify the risk/benefit ratio of different delivery techniques and dosing schedules for the administration of these medications. Studies need to address both the short-term and long-term benefits and adverse effects of inhaled steroids with particular attention to neurodevelopmental outcome.

ReviewAnti-D administration after childbirth for preventing Rhesus alloimmunisation.
The development of Rh immunisation and its prophylactic use since the 1970s has meant that severe Rhesus D (RhD) alloimmunisation is now rarely seen. ⋯ Anti-D, given within 72 hours after childbirth, reduces the risk of RhD alloimmunisation in Rhesus negative women who have given birth to a Rhesus positive infant. However the evidence on the optimal dose is limited.

The role of oral ascorbic acid (vitamin C) in the prevention and treatment of colds remains controversial despite many controlled trials. There have also been a number of efforts to synthesize and/or overview the results of these trials, and controversy over what these overviews tell us. ⋯ Long term daily supplementation with vitamin C in large doses daily does not appear to prevent colds. There appears to be a modest benefit in reducing duration of cold symptoms from ingestion of relatively high doses of vitamin C. The relation of dose to therapeutic benefit needs further exploration.

ReviewPostoperative procedures for improving fertility following pelvic reproductive surgery.
Hydrotubation with oil-soluble contrast media for unexplained infertility and adhesiolysis for infertility due to peritubal adhesions are primary procedures of recognised benefit. It is less clear whether postoperative procedures such as hydrotubation or second-look laparoscopy with adhesiolysis are beneficial following pelvic reproductive surgery. ⋯ There is insufficient evidence to support the routine practice of hydrotubation or second-look laparoscopy following female pelvic reproductive surgery. The studies on which this conclusion is based were either poor quality or underpowered. These interventions should be performed in the context of a good quality, adequately powered randomised controlled trial. Postoperative hydrotubation with fluid containing antibiotic following tubal surgery may offer benefit over hydrotubation fluid without antibiotic. A randomised controlled trial of postoperative hydrotubation with antibiotic-containing fluid versus no hydrotubation for improving fertility following tubal surgery is justified.
