Background: Although lifestyle interventions are often recommended in the management of chronic gout, the evidence from trial data of the benefits and safety of using lifestyle interventions for treating acute gout attacks have not previously been examined in a systematic review.
Objectives: The objective of this systematic review was to evaluate the benefits and safety of lifestyle interventions for the treatment of people with acute gout.
Selection criteria: Studies were included if they were randomised or quasi-randomised controlled trials which compared lifestyle interventions to another therapy (active or placebo) in patients with acute gout. Outcomes of interest were the change in participant-reported pain in the target joint(s), target joint inflammation and function, health-related quality of life (HRQoL), patient global assessment, study participant withdrawals due to adverse events (AEs) and serious adverse events (SAEs).
Background: Intrauterine insemination (IUI) is a common treatment for couples with subfertility that does not involve the fallopian tubes. It is used to bring the sperm close to the released oocyte. Another method of introducing sperm is fallopian tube sperm perfusion (FSP). Fallopian tube sperm perfusion ensures the presence of higher sperm densities in the fallopian tubes at the time of ovulation than does standard IUI. These treatments are often used in combination with ovarian hyperstimulation.
Objectives: To compare intrauterine insemination versus fallopian tube sperm perfusion in the treatment of non-tubal subfertility, for live birth and pregnancy outcomes.
Selection criteria: Randomised controlled trials (RCTs) comparing IUI with FSP in couples with non-tubal subfertility were included.
Background: Health professionals frequently recommend fever treatment regimens for children that either combine paracetamol and ibuprofen or alternate them. However, there is uncertainty about whether these regimens are better than the use of single agents, and about the adverse effect profile of combination regimens.
Objectives: To assess the effects and side effects of combining paracetamol and ibuprofen, or alternating them on consecutive treatments, compared with monotherapy for treating fever in children.
Selection criteria: We included randomized controlled trials comparing alternating or combined paracetamol and ibuprofen regimens with monotherapy in children with fever.
Background: Young children with acute diarrhoea, typically due to infectious gastroenteritis, may temporarily stop producing lactase, the intestinal enzyme that digests lactose. This means they may not digest lactose, the main sugar in milk, and this may worsen or prolong the diarrhoeal illness. However, there is uncertainty whether avoiding lactose-containing milk or milk products helps young children recover from acute diarrhoea more quickly.
Objectives: To assess if avoiding or reducing intake of lactose-containing milk or milk products shortens the duration and severity of illness in young children with acute diarrhoea. We also sought other indicators of morbidity and overall mortality.
Selection criteria: Randomized or quasi-randomized controlled trials that assessed the effects of avoiding or reducing exposure to lactose in young children under five years with acute diarrhoea.
Background: Calcium channel blocker maintenance therapy is one of the types of tocolytic therapy that may be used after an episode of threatened preterm labour (and usually an initial dose of tocolytic therapy) in an attempt to prevent the onset of further preterm contractions.
Objectives: To assess the effects of calcium channel blockers as maintenance therapy on preventing preterm birth after threatened preterm labour.
Selection criteria: Randomised controlled trials of calcium channel blockers used as maintenance therapy to prevent preterm birth after threatened preterm labour, compared with placebo or no treatment.
Background: When treating elevated blood pressure (BP), doctors often want to know what blood pressure target they should try to achieve. The standard blood pressure target in clinical practice for some time has been less than 140 - 160/90 - 100 mmHg for the general population of people with elevated blood pressure. Several clinical guidelines published in recent years have recommended lower targets (less than 130/80 mmHg) for people with diabetes mellitus. It is not known whether attempting to achieve targets lower than the standard target reduces mortality and morbidity in those with elevated blood pressure and diabetes.
Objectives: To determine if 'lower' BP targets (any target less than 130/85 mmHg) are associated with reduction in mortality and morbidity compared with 'standard' BP targets (less than 140 - 160/90 - 100 mmHg) in people with diabetes.
Selection criteria: Randomized controlled trials comparing people with diabetes randomized to lower or to standard BP targets as previously defined, and providing data on any of the primary outcomes below.
Background: Immunosuppressed cancer patients are at increased risk of serious influenza-related complications. Guidelines, therefore, recommend influenza vaccination for these patients. However, data on vaccine effectiveness in this population is lacking, and the value of vaccination in this population remains unclear.
Objectives: To assess the effectiveness of influenza vaccine in immunosuppressed adults with malignancies. The primary review outcome is all-cause mortality, preferably at the end of the influenza season. Influenza-like illness (ILI, a clinical definition), confirmed influenza, pneumonia, any hospitalization and influenza-related mortality were defined as secondary outcomes.
Selection criteria: Randomized controlled trials (RCTs), prospective and retrospective cohort studies and case-control studies were considered, comparing inactivated influenza vaccines versus placebo, no vaccination or a different vaccine, in adults (16 years and over) with cancer. We considered solid malignancies treated with chemotherapy, haematological cancer patients treated or not treated with chemotherapy, cancer patients post-autologous (up to six months after transplantation) or allogeneic (at any time) hematopoietic stem cell transplantation.
Background: Urodynamic tests are used to investigate people who have urinary incontinence or other urinary symptoms in order to make a definitive, objective diagnosis. The aim is to help select the treatment most likely to be successful. The investigations are invasive and time consuming.
Objectives: The objective of this review was to determine if treatment according to a urodynamic-based diagnosis, compared to treatment based on history and examination, led to more effective clinical care of people with urinary incontinence and better clinical outcomes.The intention was to test the following hypotheses in predefined subgroups of people with incontinence:(i) urodynamic investigations improve the clinical outcomes;(ii) urodynamic investigations alter clinical decision making;(iii) one type of urodynamic test is better than another in improving the outcomes of management of incontinence or influencing clinical decisions, or both.
Selection criteria: Randomised and quasi-randomised trials comparing clinical outcomes in groups of people who were and were not investigated using urodynamics, or comparing one type of urodynamic test against another were included. Trials were excluded if they did not report clinical outcomes.
Background: This is an update of the original Cochrane review published in Issue 2, 2007. The cause of postherpetic neuralgia is damage to peripheral neurons, dorsal root ganglia, and the dorsal horn of the spinal cord, secondary to herpes zoster infection (shingles). In postherpetic neuralgia, peripheral neurons discharge spontaneously and have lowered activation thresholds, and exhibit an exaggerated response to stimuli. Topical lidocaine dampens peripheral nociceptor sensitisation and central nervous system hyperexcitability, and may benefit patients with postherpetic neuralgia.
Objectives: To examine efficacy and safety of topical lidocaine in the treatment of postherpetic neuralgia.
Selection criteria: Randomised or quasi‐randomised trials comparing topical applications of lidocaine in patients of all ages with postherpetic neuralgia (pain persisting at the site of shingles at least one month after the onset of the acute rash).
Background: Unprotected sex is a major risk factor for disease, disability, and mortality in many areas of the world due to the prevalence and incidence of sexually transmitted infections (STI) including HIV. The male condom is one of the oldest contraceptive methods and the earliest method for preventing the spread of HIV. When used correctly and consistently, condoms can provide dual protection, i.e., against both pregnancy and HIV/STI.
Objectives: We examined comparative studies of behavioral interventions for improving condom use. We were interested in identifying interventions associated with effective condom use as measured with biological assessments, which can provide objective evidence of protection.
Selection criteria: Studies could be either randomized or nonrandomized. They examined a behavioral intervention for improving condom use. The comparison could be another behavioral intervention, usual care, or no intervention. The experimental intervention had an educational or counseling component to encourage or improve condom use. It addressed preventing pregnancy as well as the transmission of HIV/STI. The focus could be on male or female condoms and targeted to individuals, couples, or communities. Potential participants included heterosexual women and heterosexual men.Studies had to provide data from test results or records on a biological outcome: pregnancy, HIV/STI, or presence of semen as assessed with a biological marker, e.g., prostate-specific antigen. We did not include self-reported data on protected or unprotected sex, due to the limitations of recall and social desirability bias. Outcomes were measured at least three months after the behavioral intervention started.
Background: Plasmodium vivax infections are an important contributor to the malaria burden worldwide. The World Health Organization recommends a 14-day course of primaquine (0.25 mg/kg/day, giving an adult dose of 15 mg/day) to eradicate the liver stage of the parasite and prevent relapse of the disease. Many people find a 14-day primaquine regimen difficult to complete, and there is a potential risk of haemolytic anaemia in people with glucose-6-phosphate-dehydrogenase enzyme (G6PD) deficiency. This review evaluates primaquine in P. vivax, particularly alternatives to the standard 14-day course.
Objectives: To compare alternative primaquine regimens to the recommended 14-day regimen for preventing relapses (radical cure) in people with P. vivax malaria treated for blood stage infection with chloroquine. We also summarize trials comparing primaquine to no primaquine that led to the recommendation for the 14-day regimen.
Selection criteria: Randomized controlled trials (RCTs) and quasi-RCTs comparing various primaquine dosing regimens with the standard primaquine regimen (15 mg/day for 14 days), or with no primaquine, in people with vivax malaria treated for blood stage infection with chloroquine.
Background: Meningococcal disease is a contagious bacterial infection caused by Neisseria meningitidis (N. meningitidis). Household contacts have the highest risk of contracting the disease during the first week of a case being detected. Prophylaxis is considered for close contacts of people with a meningococcal infection and populations with known high carriage rates.
Objectives: To study the effectiveness, adverse events and development of drug resistance of different antibiotics as prophylactic treatment regimens for meningococcal infection.
Selection criteria: Randomised controlled trials (RCTs) or quasi-RCTs addressing the effectiveness of different antibiotics for: (a) prophylaxis against meningococcal disease; (b) eradication of N. meningitidis.
Background: Plasmodium vivax is an important cause of malaria in many parts of Asia and South America, and parasite resistance to the standard treatment (chloroquine) is now high in some parts of Oceania. This review aims to assess the current treatment options in the light of increasing chloroquine resistance.
Objectives: To compare artemisinin-based combination therapies (ACTs) with alternative antimalarial regimens for treating acute uncomplicated P. vivax malaria.
Selection criteria: Randomized controlled trials comparing ACTs versus standard therapy, or comparing alternative ACTs, in adults and children with uncomplicated P. vivax malaria.
Background: Postnatal depression is a medical condition that affects many women and the development of their infants. There is a lack of evidence for treatment and prevention strategies that are safe for mothers and infants. Certain dietary deficiencies in a pregnant or postnatal woman's diet may cause postnatal depression. By correcting these deficiencies postnatal depression could be prevented in some women. Specific examples of dietary supplements aimed at preventing postnatal depression include: omega-3 fatty acids, iron, folate, s-adenosyl-L-methionine, cobalamin, pyridoxine, riboflavin, vitamin D and calcium.
Objectives: To assess the benefits of dietary supplements for preventing postnatal depression either in the antenatal period, postnatal period, or both.
Selection criteria: Randomised controlled trials, involving women who were pregnant or who had given birth in the previous six weeks, who were not depressed or taking antidepressants at the commencement of the trials. The trials could use as intervention any dietary supplementation alone or in combination with another treatment compared with any other preventive treatment, or placebo, or standard clinical care.
Background: Axillary dissection is commonly performed for breast carcinoma. It is uncertain whether insertion of a drain reduces complication rates.
Objectives: To assess the effects of wound drainage after axillary dissection for breast carcinoma on the incidence of postoperative seroma formation. Secondary outcome measures include the incidence of infection and length of hospital stay.
Selection criteria: All randomised controlled trials (RCTs) comparing wound drainage versus no wound drainage in individuals after axillary dissection for the treatment of breast carcinoma were included. All disease stages were considered. Breast-conserving surgery and mastectomy were considered. Patients undergoing sentinel node biopsy without axillary dissection were not included. No limits were applied to language or study location. Two review authors independently determined the eligibility of each study.
Background: When orthodontic treatment is provided with fixed appliances, it is sometimes necessary to move the upper molar teeth backwards (distalise) to create space or help to overcome anchorage requirements. This can be achieved with the use of extraoral or intraoral appliances. The most common appliance is extraoral headgear, which requires considerable patient co-operation. Further, reports of serious injuries have been published. Intraoral appliances have been developed to overcome such shortcomings. The comparative effects of extraoral and intraoral appliances have not been fully evaluated.
Objectives: To assess the effects of orthodontic treatment for distalising upper first molars in children and adolescents.
Selection criteria: Randomised clinical trials involving the use of removable or fixed orthodontic appliances intended to distalise upper first molars in children and adolescents.
Background: Dietary antioxidants, such as vitamin C, in the epithelial lining and lining fluids of the lung may be beneficial in the reduction of oxidative damage (Arab 2002). They may therefore be of benefit in reducing symptoms of inflammatory airway conditions such as asthma, and may also be beneficial in reducing exercise-induced bronchoconstriction, which is a well-recognised feature of asthma and is considered a marker of airways inflammation. However, the association between dietary antioxidants and asthma severity or exercise-induced bronchoconstriction is not fully understood.
Objectives: To examine the effects of vitamin C supplementation on exacerbations and health-related quality of life (HRQL) in adults and children with asthma or exercise-induced bronchoconstriction compared to placebo or no vitamin C.
Selection criteria: We included randomised controlled trials (RCTs). We included both adults and children with a diagnosis of asthma. In separate analyses we considered trials with a diagnosis of exercise-induced bronchoconstriction (or exercise-induced asthma). We included trials comparing vitamin C supplementation with placebo, or vitamin C supplementation with no supplementation. We included trials where the asthma management of both treatment and control groups provided similar background therapy. The primary focus of the review is on daily vitamin C supplementation to prevent exacerbations and improve HRQL. The short-term use of vitamin C at the time of exacerbations or for cold symptoms in people with asthma are outside the scope of this review.
Background: Tobacco smoking in pregnancy remains one of the few preventable factors associated with complications in pregnancy, stillbirth, low birthweight and preterm birth and has serious long-term implications for women and babies. Smoking in pregnancy is decreasing in high-income countries, but is strongly associated with poverty and increasing in low- to middle-income countries.
Objectives: To assess the effects of smoking cessation interventions during pregnancy on smoking behaviour and perinatal health outcomes.
Selection criteria: Randomised controlled trials, cluster-randomised trials, randomised cross-over trials, and quasi-randomised controlled trials (with allocation by maternal birth date or hospital record number) of psychosocial smoking cessation interventions during pregnancy.
Background: The purpose of low-vision rehabilitation is to allow people to resume or to continue to perform daily living tasks, with reading being one of the most important. This is achieved by providing appropriate optical devices and special training in the use of residual-vision and low-vision aids, which range from simple optical magnifiers to high-magnification video magnifiers.
Objectives: To assess the effects of reading aids for adults with low vision.
Selection criteria: This review includes randomised and quasi-randomised trials in which any device or aid used for reading had been compared to another device or aid in people aged 16 or over with low vision as defined by the study investigators.
Background: Uterine fibroids, also called uterine leiomyomas or myomas, are the most common benign tumours in women of reproductive age. Albeit generally benign, uterine ﬁ broids can have a major impact on women's health and quality of life by contributing to abnormal uterine bleeding and causing pelvic pressure symptoms (such as increased urinary frequency, pelvic pain and constipation). Traditional treatments for symptomatic ﬁ broids include a variety of surgical techniques. However, because of the high recurrence rate, as well as possible pain and infertility caused by the formation of postoperative adhesions, this approach may not be advisable. Safer and more effective medical therapy has long been awaited. Both in vitro studies and clinical trials have suggested that use of the aromatase inhibitors (AIs), a class of anti-oestrogens, might inhibit ﬁ broid growth, thereby eliminating the need for surgery.
Objectives: To evaluate the effectiveness and safety of aromatase Inhibitors (AIs) in women with uterine fibroids.
Selection criteria: Randomised controlled trials (RCTs) in women of reproductive age comparing the effects of any AI versus placebo, no treatment or any medical treatment/surgery were included.
Background: This review is an update of a previously published review in The Cochrane Database of Systematic Reviews Issue 3, 2009 on single dose oral dexibuprofen (S(+)-ibuprofen) for acute postoperative pain in adults.Dexibuprofen is a non-steroidal anti-inflammatory drug (NSAID) licensed for use in rheumatic disease and other musculoskeletal disorders in the UK, and widely available in other countries worldwide. It is an active isomer of ibuprofen. This review sought to evaluate the efficacy and safety of oral dexibuprofen in acute postoperative pain, using clinical studies in patients with established pain, and with outcomes measured primarily over four to six hours, using standard methods. This type of study has been used for many decades to establish that drugs have analgesic properties.
Objectives: To assess the efficacy and adverse effects of single dose oral dexibuprofen for acute postoperative pain using methods that permit comparison with other analgesics evaluated in standardised studies using almost identical methods and outcomes.
Selection criteria: Randomised, double blind, placebo-controlled clinical studies of oral dexibuprofen for relief of acute postoperative pain in adults.
Background: The most commonly used types of phototherapy for treating psoriasis are narrow-band ultraviolet B (NB-UVB); broad-band ultraviolet B (BB-UVB), which includes selective (delivering radiation with a wavelength range of 305 to 325 nm) and conventional BB-UVB (280 to 320 nm); and psoralen ultraviolet A photochemotherapy (oral or bath PUVA). There is substantial controversy regarding their efficacy when compared with each other.
Objectives: To assess the effects of narrow-band ultraviolet B phototherapy versus broad-band ultraviolet B or psoralen ultraviolet A photochemotherapy for psoriasis.
Selection criteria: We included all randomised controlled trials (RCTs) that compared NB-UVB phototherapy with BB-UVB or PUVA for treating psoriasis, which included chronic plaque psoriasis (CPP), guttate psoriasis (GP), and palmoplantar psoriasis (PPP).
Background: This is an update of a review first published in The Cochrane Library in Issue 4, 2008, and updated in Issue 3, 2012. Celecoxib is a selective cyclo-oxygenase-2 (COX-2) inhibitor usually prescribed for the relief of chronic pain in osteoarthritis and rheumatoid arthritis. Celecoxib is believed to be associated with fewer upper gastrointestinal adverse effects than conventional non-steroidal anti-inflammatory drugs (NSAIDs). Its effectiveness in acute pain was demonstrated in the earlier reviews.
Objectives: To assess analgesic efficacy and adverse effects of a single oral dose of celecoxib for moderate to severe postoperative pain in adults.
Selection criteria: We included randomised, double-blind, placebo-controlled trials (RCTs) of adults prescribed any dose of oral celecoxib or placebo for acute postoperative pain.
Background: Pelargonium sidoides (P. sidoides), also known as Umckaloabo, is a herbal remedy thought to be effective in the treatment of acute respiratory infections (ARIs).
Objectives: To assess the efficacy and safety of P. sidoides for the treatment of ARIs in children and adults.
Selection criteria: Double-blind, randomized controlled trials (RCTs) examining the efficacy of P. sidoides preparations in ARIs compared to placebo or any other treatment. Complete resolution of all symptoms was defined as the primary outcome; in addition, we examined resolution of predefined key symptoms.
