Review Meta AnalysisPotassium containing toothpastes for dentine hypersensitivity.
Dentine hypersensitivity may be defined as the pain arising from exposed dentine, typically in response to external stimuli, and which cannot be explained by any other form of dental disease. Many treatment regimens have been recommended over the years, and in recent years particular attention has been focused on toothpastes containing various potassium salts. ⋯ The evidence generated by this review is based on a small number of individuals. Furthermore, the effect varies with the methods applied for assessing the sensitivity. Thus no clear evidence is available for the support of potassium containing toothpastes for dentine hypersensitivity.

Tramadol is increasingly used for the treatment of osteoarthritis because, in contrast to nonsteroidal anti-inflammatory drugs (NSAIDs), tramadol does not produce gastrointestinal bleeding or renal problems, and does not affect articular cartilage. ⋯ Tramadol or tramadol/paracetamol decreases pain intensity, produces symptom relief and improves function, but these benefits are small. Adverse events, although reversible and not life threatening, often cause participants to stop taking the medication and could limit tramadol or tramadol plus paracetamol usefulness.

Review Meta AnalysisHaloperidol alone or in combination for acute mania.
The main objectives in treating mania are to control dangerous behaviour, reduce suicide, produce appropriate acute sedation and shorten the episode of mood disturbance. Among different drugs, haloperidol has for many years been used in treating psychotic patients, but it has a troublesome side effect profile. ⋯ There is some evidence that haloperidol is an effective treatment for acute mania. From the limited data available, there was no difference in overall efficacy of treatment between haloperidol and olanzapine or risperidone. Some evidence suggests that haloperidol could be less effective than aripiprazole. Referring to tolerability, when considering the poor evidence comparing drugs, clinicians and patients should consider different side effect profiles as an important issue to inform their choice.

Pain is the most frequent symptom experienced by cancer patients, its intensity dependent on the site of the tumour. Tumours that compromise bone or nervous structures due to the bone destruction process are the most painful. There are several treatments to deal with pain (and other symptoms) caused by bone metastases. The hormone, calcitonin, has the potential to relieve pain, and also retain bone density, thus reducing the risk of fractures. This review is an update of a previously published review in The Cochrane Library (Issue 3, 2003) on this topic. ⋯ The limited evidence currently available does not support the use of calcitonin to control pain from bone metastases. Since the last version of this review, none of the new relevant studies have provided additional information on this treatment, in contrast to other therapeutic approaches that should be considered.

Review Meta AnalysisPreoperative chemotherapy for resectable thoracic esophageal cancer.
Surgery has been the treatment of choice for localized esophageal cancer. A number of studies have investigated whether preoperative chemotherapy followed by surgery leads to an improvement in cure rates but the individual reports have been conflicting. An explicit systematic update of the role of preoperative chemotherapy in the treatment of resectable thoracic esophageal cancer is, therefore, warranted. ⋯ In summary, preoperative chemotherapy plus surgery may offer a survival advantage compared to surgery alone for resectable thoracic esophageal cancer, but the evidence is inconclusive. There is some evidence of toxicity and preoperative mortality associated with chemotherapy.
