Review Meta AnalysisEndometrial resection and ablation 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 these techniques must be considered to be still under development, requiring refinement and investigation. ⋯ Endometrial ablation techniques offer a less invasive surgical alternative to hysterectomy. The rapid development of a number of new methods of endometrial destruction has made systematic comparisons between individual methods and with the 'gold standard' first-generation techniques difficult. Most of the newer techniques are technically easier to perform than traditional hysteroscopy-based methods but technical difficulties with the new equipment need to be addressed. Overall, the existing evidence suggests that success, satisfaction rates and complication profiles of newer techniques of ablation compare favourably with hysteroscopic techniques.

Bacillus Calmette-Guerín (BCG) is a live attenuated vaccine to prevent tuberculosis, routinely administered at birth as part of the World Health Organization global expanded immunisation programme. Given intradermally, it can cause adverse reactions, including local, regional, distant and disseminated manifestations that may cause parental distress. Rarely, it can cause serious illness and even death. Among those patients with immunocompromised conditions, such as the human immunodeficiency virus (HIV) infection, the complication rate is even higher. ⋯ It is unclear if oral antibiotics (isoniazid, erythromycin, or a combination of isoniazid plus rifampicin) are effective for the resolution of BCG-induced disease. Most non-suppurated lymphadenitis will resolve without treatment in 4 to 6 months. Patients with lymphadenitis abscess might benefit from needle aspiration and possibly local instillation of isoniazid could shorten recovery time. Included studies were generally small and could be better conducted. Further research should evaluate the use of needle aspiration and local instillation of isoniazid in fluctuant nodes. Therapeutic and preventive measures in HIV-infected infants could be important given the higher risk of negative outcomes in this group.

Review Meta AnalysisInterventions for preventing and treating pelvic and back pain in pregnancy.
More than two-thirds of pregnant women experience low-back pain (LBP) and almost one-fifth experience pelvic pain. Pain increases with advancing pregnancy and interferes with work, daily activities and sleep. ⋯ Moderate-quality evidence suggested that acupuncture or exercise, tailored to the stage of pregnancy, significantly reduced evening pelvic pain or lumbo-pelvic pain more than usual care alone, acupuncture was significantly more effective than exercise for reducing evening pelvic pain, and a 16- to 20-week training program was no more successful than usual prenatal care at preventing pelvic or LBP. Low-quality evidence suggested that exercise significantly reduced pain and disability from LBP.There was low-quality evidence from single trials for other outcomes because of high risk of bias and sparse data; clinical heterogeneity precluded pooling. Publication bias and selective reporting cannot be ruled out.Physiotherapy, OMT, acupuncture, a multi-modal intervention, or the addition of a rigid pelvic belt to exercise seemed to relieve pelvic or back pain more than usual care alone. Acupuncture was more effective than physiotherapy at relieving evening lumbo-pelvic pain and disability and improving pain and function when it was started at 26- rather than 20-weeks' gestation, although the effects were small.There was no significant difference in LBP and function for different support belts, exercise, neuro emotional technique or spinal manipulation (SMT), or in evening pelvic pain between deep and superficial acupuncture.Very low-quality evidence suggested a specially-designed pillow may reduce night-time LBP.Further research is very likely to have an important impact on our confidence in the estimates of effect and is likely to change the estimates. Future research would benefit from the introduction of an agreed classification system that can be used to categorise women according to presenting symptoms.

Review Meta AnalysisLung lavage for meconium aspiration syndrome in newborn infants.
Meconium aspiration syndrome (MAS) can occur when a newborn infant inhales a mixture of meconium and amniotic fluid into the lungs around the time of delivery. Other than supportive measures, little effective therapy is available. Lung lavage may be a potentially effective treatment for MAS by virtue of removing meconium from the airspaces and altering the natural course of the disease. ⋯ In infants with meconium aspiration syndrome, lung lavage with diluted surfactant may be beneficial, but additional controlled clinical trials of lavage therapy should be conducted to confirm the treatment effect, to refine the method of lavage treatment, and to compare lavage treatment with other approaches, including surfactant bolus therapy. Long-term outcomes should be evaluated in further clinical trials.

Review Meta AnalysisSurgical interventions for treating radial head fractures in adults.
Radial head fractures are the most common type of elbow fracture and can severely affect the function of the elbow. There is uncertainty and controversy about when surgery is indicated as well as what type of surgical intervention is best. ⋯ Only tentative conclusions can be drawn from the available evidence in this review. Compared with ORIF, there was some evidence that radial head replacement had better elbow function and fewer adverse events for Mason type III radial head fractures in the short term. However, the evidence is of low quality and it is unknown whether these results would apply in the longer term or more generally. Using biodegradable implants may be as good as metallic implants for fixation of some usually more stable fractures but more evidence is needed to confirm this. There is a need for good quality evidence for addressing the areas of uncertainty for the surgical treatment of radial head fractures.
