Review Meta AnalysisSedatives for opiate withdrawal in newborn infants.
Neonatal abstinence syndrome (NAS) due to opiate withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss and seizures. Treatments used to ameliorate symptoms and reduce morbidity include opiates, sedatives and non-pharmacological treatments. ⋯ In newborn infants with NAS, there is no evidence that phenobarbitone compared with supportive care alone reduces treatment failure; however, phenobarbitone may reduce the daily duration of supportive care needed. Phenobarbitone, compared to diazepam, reduces treatment failure. In infants treated with an opiate, the addition of phenobarbitone may reduce withdrawal severity. Further trials are required to determine if this finding is applicable when a higher initial dose of opiate is used, and determine the effects of phenobabritone on infant development. There is insufficient evidence to support the use of chlorpromazine or clonidine in newborn infants with NAS. Clonidine and chlorpromazine should only be used in the context of a randomised clinical trial. This review should be taken in conjunction with the review "Opiate treatment for opiate withdrawal in newborn infants" (Osborn 2002a) which indicates that an opiate is the preferred initial therapy for NAS.

Review Meta AnalysisEndometrial destruction techniques for heavy menstrual bleeding.
Heavy menstrual bleeding (HMB) is a significant health problem in premenopausal women; it can reduce their quality of life and cause anaemia. First-line therapy has traditionally been medical therapy but this is frequently ineffective. On the other hand, hysterectomy is obviously 100% effective in stopping bleeding but is more costly and can cause severe complications. Endometrial ablation is less invasive and preserves the uterus, although long-term studies have found that the costs of ablative surgery approach the cost of hysterectomy due to the requirement for repeat procedures. A large number of techniques have been developed to 'ablate' (remove) the lining of the endometrium. The gold standard techniques (laser, transcervical resection of the endometrium and rollerball) require visualisation of the uterus with a hysteroscope and, although safe, require skilled surgeons. A number of newer techniques have recently been developed, most of which are less time consuming. However, hysteroscopy may still be required as part of the ablative techniques and some of them must be considered to be still under development, requiring refinement and investigation. ⋯ Endometrial ablation techniques continue to play an important role in the management of HMB. The rapid development of a number of new methods of endometrial destruction has made systematic comparisons between methods and with the 'gold standard' of transcervical resection of the endometrium (TCRE) difficult. Most of the newer techniques are technically easier than hysteroscopy-based methods to perform. However, uterine perforation, which is the major complication of endometrial ablation, cannot be excluded without hysteroscopy. Overall, the existing evidence suggests that success rates and complication profiles of newer techniques of ablation compare favourably with TCRE, although technical difficulties with new equipment need to be ironed out.

Vitamin C supplementation may help reduce the risk of pregnancy complications like pre-eclampsia, intrauterine growth restriction and maternal anaemia. There is a need to evaluate the efficacy and safety of vitamin C supplementation in pregnancy. ⋯ The data are too few to say if vitamin C supplementation, alone or combined with other supplements, is beneficial during pregnancy. Preterm birth may have been increased with vitamin C supplementation.

Adalimumab is a fully human anti-TNFalpha monoclonal antibody. Published studies indicate that its use in patients with RA can be effective and safe. ⋯ On the basis of the studies reviewed here, adalimumab in combination with methotrexate is efficacious and safe in the treatment of the rheumatoid arthritis. Adalimumab 40 mg sc e.o.w. and 20 mg e.w. slows the radiographic progression at 52 weeks. Adalimumab in combination with DMARDs other than methotrexate is also efficacious and safe, even though data from one only study are available and the number of patients in each group is low. Adalimumab in monotherapy is efficacious and safe in the treatment of the rheumatoid arthritis but the effect size is lower than with combined therapy.

Review Meta AnalysisGlutamine supplementation to prevent morbidity and mortality in preterm infants.
Glutamine endogenous biosynthesis may be insufficient for tissue needs in states of metabolic stress. Trials in adults have suggested that glutamine supplementation improves clinical outcomes in critically ill adults. It has been suggested that glutamine supplementation may benefit preterm infants, particularly very low birth weight infants. ⋯ The available data from good quality randomised controlled trials suggest that glutamine supplementation does not confer clinically significant benefits for preterm infants. The narrow confidence intervals for the effect size estimates suggest that a further trial of this intervention is not a research priority.
