ReviewChemical pleurodesis versus surgical intervention for persistent and recurrent pneumothoraces in cystic fibrosis.
Pneumothorax is a potentially life-threatening complication for people with cystic fibrosis. Spontaneous pneumothorax is the presence of air in the pleural space and can be subdivided into first episode and recurrent. The recurrence of pneumothorax is when it occurs on the same side seven days or more after initial resolution. A pneumothorax is persistent if the air leak lasts for more than five days (Schidlow 1993). Managing spontaneous pneumothoraces is controversial and there is no standard treatment. Medical and surgical intervention are the two main categories for the treatment of recurrent pneumothoraces in people with cystic fibrosis. While surgical interventions are felt to be more effective in people without cystic fibrosis, the complications directly related to the procedure, as well as the post-operative complications make surgical interventions riskier for people with cystic fibrosis. Additionally, these interventions have the potential to make people with cystic fibrosis ineligible for lung transplantation in the future. Therefore, the benefits and side effects or disadvantages for the medical and surgical treatment of recurrent pneumothoraces in people with cystic fibrosis need to be systematically reviewed. ⋯ Pneumothorax is a potentially life-threatening complication for people with cystic fibrosis and the management of spontaneous pneumothoraces remains a topic of considerable controversy. Medical and surgical intervention are the two main categories for the treatment of recurrent pneumothoraces in this population. However, it is disappointing that neither intervention has been assessed by randomised controlled trials. This systematic review identifies the need for a multicentre randomised controlled trial assessing both efficacy and possible adverse effects of the use of chemical pleurodesis versus surgical interventions for the treatment of persistent and recurrent pneumothoraces in people with cystic fibrosis.

Review Meta AnalysisNeoadjuvant chemotherapy plus surgery versus surgery for cervical cancer.
A previous systematic review found that giving neoadjuvant chemotherapy before surgery improved survival compared with radiotherapy. However, the role of neoadjuvant chemotherapy followed by surgery versus surgery alone is still unclear. ⋯ Both OS and PFS were improved with neoadjuvant chemotherapy. Although the effects were less clear on all other pre-specified outcomes, they all tended to be in favour of neoadjuvant chemotherapy. Whilst these results appear to indicate that neoadjuvant chemotherapy may offer a benefit over surgery alone for women with early-stage or locally-advanced cervical cancer, the evidence is based on only a small number of trials, and further research may be warranted.

Vaginismus is an involuntary contraction of the vaginal muscles which makes sexual intercourse difficult or impossible. It is one of the more common female psychosexual problems. Various therapeutic strategies for vaginismus, such as sex therapy and desensitisation, have been proposed, and uncontrolled case series appear promising. ⋯ A clinically relevant effect of systematic desensitisation when compared with any of the control interventions cannot be ruled out. None of the included trials compared other behaviour therapies (e.g. cognitive behaviour therapy, sex therapy) to pharmacological interventions. The findings are limited by the evidence available and as such conclusions about the efficacy of interventions for the treatment of vaginismus should be drawn cautiously.

Review Meta AnalysisOral betamimetics for maintenance therapy after threatened preterm labour.
Some women who have threatened to give birth prematurely, subsequently settle. They may then take oral tocolytic maintenance therapy to prevent preterm birth and to prolong gestation. ⋯ Available evidence does not support the use of oral betamimetics for maintenance therapy after threatened preterm labour.

Mild cognitive impairment (MCI) has been proposed as a condition of intermediate symptomatology between the cognitive changes of ageing and fully developed symptoms of dementia. Treatment in the stages of MCI may delay the deterioration of cognitive impairment and delay the progression to dementia. Currently, the treatments for Alzheimer's disease have been focused on increasing acetylcholine levels in the brain. However, these drugs have not been proven to be effective for MCI and have numerous side effects. Huperzine A may have some beneficial effects in MCI. ⋯ The currently available evidence is insufficient to assess the potential for huperzine A in the treatment of MCI. Randomised double-blind placebo-controlled trials are needed.
