Antibiotic treatment of acute bronchitis, which is one of the most common illnesses seen in primary care, is controversial. Most clinicians prescribe antibiotics in spite of expert recommendations against this practice. ⋯ Overall, antibiotics appear to have a modest beneficial effect in patients who are diagnosed with acute bronchitis. The magnitude of this benefit, however, is similar to that of the detriment from potential adverse effects.

Review Meta AnalysisSpinal versus epidural anaesthesia for caesarean section.
Regional anaesthesia (spinal or epidural anaesthesia) for caesarean section is the preferred option when balancing risks and benefits to the mother and her fetus. Spinal anaesthesia for caesarean section is thought to be advantageous due to simplicity of technique, rapid administration and onset of anaesthesia, reduced risk of systemic toxicity and increased density of spinal anaesthetic block. ⋯ Both spinal and epidural techniques are shown to provide effective anaesthesia for caesarean section. Both techniques are associated with moderate degrees of maternal satisfaction. Spinal anaesthesia has a shorter onset time, but treatment for hypotension is more likely if spinal anaesthesia is used. No conclusions can be drawn about intraoperative side-effects and postoperative complications because they were of low incidence and/or not reported.

Review Meta AnalysisOver-the-counter medications for acute cough in children and adults in ambulatory settings.
Acute cough due to upper respiratory tract infection (URTI) is a common symptom. Many health practitioners recommend non-prescription over-the-counter (OTC) medicines as a first-line treatment for cough, but there is little evidence as to whether these drugs are effective. ⋯ There is no good evidence for or against the effectiveness of OTC medicines in acute cough. The results of this review have to be interpreted with caution due to differences in study designs, populations, interventions and outcomes between studies. The numbers of studies in each group were small, and studies often showed conflicting results. Effect sizes in many studies were unclear and it is questionable as to whether all of the positive results are clinically relevant. More evidence about the effectiveness of OTC cough preparations would be helpful, as identification of effective self-care treatments may help reduce the burden of days lost at work due to acute cough as well as the number of consultations in primary care. Identification of ineffective preparations could avoid costs for consumers and health care providers.

Review Meta AnalysisNon-invasive interventions for improving well-being and quality of life in patients with lung cancer.
Lung cancer is one of the leading causes of death globally. Despite advances in treatment, outlook for the majority of patients remains grim and most face a pessimistic outlook accompanied by sometimes devastating effects on emotional and psychological health. Although chemotherapy is accepted as an effective treatment for advanced lung cancer, the high prevalence of treatment-related side effects as well the symptoms of disease progression highlight the need for high quality palliative and supportive care to minimise symptom distress and to promote quality of life. ⋯ Nurse follow-up programmes and a nurse intervention to manage breathlessness may produce beneficial effects. Psychotherapeutic study indicates that counselling may help patients cope more effectively with emotional symptoms, but the evidence is not conclusive. Findings from the included studies reinforce the necessity for increased training and education of healthcare professionals giving in these interventions. More research, of higher methodological quality is needed in this area to explore possible underlying explanatory mechanisms.

Review Meta AnalysisOne topical fluoride (toothpastes, or mouthrinses, or gels, or varnishes) versus another for preventing dental caries in children and adolescents.
Topical fluorides in the form of toothpaste, mouthrinse, varnish and gel are effective caries preventive measures. However, there is uncertainty about the relative value of these interventions. ⋯ Fluoride toothpastes in comparison to mouthrinses or gels appear to have a similar degree of effectiveness for the prevention of dental caries in children. There is no clear suggestion that fluoride varnish is more effective than mouthrinses and the evidence for the comparative effectiveness of fluoride varnishes and gels, and mouthrinses and gels is inconclusive. No conclusions about adverse effects could be reached, because no data were reported on in the trials. Acceptance is likely to be greater for fluoride toothpaste.
