Review Meta AnalysisShouldice technique versus other open techniques for inguinal hernia repair.
Inguinal hernia repair is the most frequent operation in general surgery. There are several techniques: the Shouldice technique is sometimes considered the best method but different techniques are used as the "gold standard" for open hernia repair. Outcome measures, such as recurrence rates, complications and length of post operative stay, vary considerably among the various techniques. ⋯ Shouldice herniorrhaphy is the best non-mesh technique in terms of recurrence, though it is more time consuming and needs a slightly longer post-operative hospital stay. The use of mesh is associated with a lower rate of recurrence. The quality of included studies, assessed with jaded scale, were low. Patients have similar characteristic in the treatment and control group but seems more healthy than in general population, this features may affect the dimension of effect in particularly recurrence rate could be higher in general population. Lost to follow-up were similar in the treatment and control group but the reasons were often not reported. The length of follow-up vary broadly among the studies from 1 year to 13.7 year.

Review Meta AnalysisTrastuzumab containing regimens for early breast cancer.
Approximately one-fifth of women who develop early breast cancer have HER2-positive tumours, which if untreated, have a worse prognosis than HER2-negative tumours. Trastuzumab is a selective treatment targeting the HER2 pathway. Although the results on efficacy seem to support its use, there are potential cardiac toxicities which need to be considered, especially for women at lower risk of recurrence, or those at increased cardiovascular risk. ⋯ Trastuzumab significantly improves OS and DFS in HER2-positive women with early and locally advanced breast cancer, although it also significantly increases the risk of CHF and LVEF decline. The available subgroup analyses are limited by the small number of studies. Studies that administered trastuzumab concurrently or sequentially did not differ significantly in efficacy. Shorter duration of therapy may reduce cardiotoxicity and maintain efficacy, however there is insufficient evidence at present to conclude this due to small numbers of patients in these trials.

Review Meta AnalysisMonoamine oxidase inhibitors (MAOIs) for fibromyalgia syndrome.
Fibromyalgia (FM) syndrome is a chronic condition of unknown aetiology characterised by musculoskeletal pain that often co-exists with sleep disturbance, cognitive dysfunction and fatigue. Patients often report high disability levels and poor quality of life. Since there is no specific treatment that alters the pathogenesis of FM, drug therapy focuses on pain reduction and improvement of other bothersome symptoms. ⋯ Data suggest that the effectiveness of MAOIs for the treatment of FM symptoms is limited. Although we observed a moderate effect size on pain and a small one on tender points, these results should be taken with caution as they are only based on two studies with a small number of patients and inconsistent risk of bias among them.

Review Meta AnalysisHelminth therapy (worms) for allergic rhinitis.
Allergic rhinitis is a disorder of the nasal membranes and surrounding tissues, and a worldwide cause of illness and disability. Helminths are complex tissue-dwelling or lumen-dwelling organisms that inhabit larger organisms and are frequently asymptomatic. Helminths modulate the natural immune responses of their human hosts, and may prevent or cure immune-mediated or allergic diseases (e.g. allergic rhinitis) in the host. Non-randomised studies support this hypothesis. ⋯ There is currently insufficient evidence on the efficacy, tolerability and likely costs of helminth therapy to support its use in the routine management of allergic rhinitis. Administered to humans in carefully measured doses, helminths appear to be safe. More preclinical studies should be performed, before larger and extended duration trials of helminths for allergic rhinitis are carried out. Future studies should collect and report comparative data on the costs of helminth therapy versus conventional pharmacotherapy.

Ingrowing toenails are a common problem in which part of the nail penetrates the skinfold alongside the nail, creating a painful area. Different non-surgical and surgical interventions for ingrowing toenails are available, but there is no consensus about a standard first-choice treatment. ⋯ Surgical interventions are more effective than non-surgical interventions in preventing the recurrence of an ingrowing toenail.In the studies comparing a surgical intervention to a surgical intervention with the application of phenol, the addition of phenol is probably more effective in preventing recurrence and regrowth of the ingrowing toenail. Because there is only one study in which the surgical interventions in both study arms were equal, more studies have to be done to confirm these outcomes.Postoperative interventions do not decrease the risk of postoperative infection, postoperative pain, or healing time.
