ReviewPhenobarbitone versus phenytoin monotherapy for epilepsy: an individual participant data review.
This is an update of a Cochrane Review first published in 2001, and last updated in 2013. This review is one in a series of Cochrane Reviews investigating pair-wise monotherapy comparisons.Epilepsy is a common neurological condition in which abnormal electrical discharges from the brain cause recurrent unprovoked seizures. It is believed that with effective drug treatment, up to 70% of individuals with active epilepsy have the potential to become seizure-free and go into long-term remission shortly after starting drug therapy with a single antiepileptic drug in monotherapy.Worldwide, particularly in the developing world, phenytoin and phenobarbitone are commonly used antiepileptic drugs, primarily because they are inexpensive. The aim of this review is to summarise data from existing trials comparing phenytoin and phenobarbitone. ⋯ Low-certainty evidence from this review suggests that phenytoin may be a more effective drug than phenobarbitone in terms of treatment retention (treatment failures due to lack of efficacy or adverse events or both). Moderate-certainty evidence from this review also indicates no differences between the drugs in terms of time to seizure recurrence and seizure remission.However, the trials contributing to the analyses had methodological inadequacies and methodological design differences that may have impacted upon the results of this review. Therefore, we do not suggest that results of this review alone should form the basis of a treatment choice for a patient with newly onset seizures. We recommend that future trials should be designed to the highest quality possible with consideration of masking, choice of population, classification of seizure type, duration of follow-up, choice of outcomes and analysis, and presentation of results.

ReviewUltrasound-guided transvaginal ovarian needle drilling for clomiphene-resistant polycystic ovarian syndrome in subfertile women.
Ovulatory disturbance is a key diagnostic feature of polycystic ovarian syndrome (PCOS), leading to infertility and correspondingly heavy disease burden. Many therapeutic strategies have been used to induce ovulation for women with PCOS who are infertile. Ultrasound-guided transvaginal ovarian needle drilling (UTND) is a novel surgical method used to induce ovulation for women with clomiphene-resistant PCOS at the outpatients clinic. Nevertheless, the quality in most of the studies seemed low, and the safety and efficacy of UTND is still uncertain. ⋯ Based on very low-quality evidence, It is uncertain whether there is any difference in pregnancy rate, incidence of surgical complications, and miscarriage rate between UTND and LOD in women with clomiphene-resistant PCOS. UTND may lead to a slight decrease in ovulation rate when compared to LOD. No studies reported on the outcomes live birth rate, incidence of OHSS, and multiple pregnancy rate. No studies reported on the main outcomes live birth and surgical complications for the comparison UTND combined with gonadotrophins versus gonadotrophins alone. The evidence for the outcomes OHSS, pregnancy, ovulation, miscarriage, and multiple pregnancy in this comparison was of very low quality. Thus, it is unclear if there is a difference in any of the outcomes between UTND combined with gonadotrophins versus gonadotrophins alone.

ReviewFamilies and Schools Together (FAST) for improving outcomes for children and their families.
Parents and carers have a major influence on children's learning and development from birth, through the school years, and into adulthood. Parental contributions to education include providing a secure environment in which to learn, providing intellectual stimulation, transmitting social norms and values, shaping the child's resilience through fostering literacy and problem-solving, and encouraging personal and social aspiration. Increasingly, providers of formalised education are recognising the primary role of parents, carers, and the wider family, as well as peers and the environment, in shaping children's education, health, and life experiences. ⋯ Given these results, it is hard to support the assertion that assignment to FAST is associated with important positive outcomes for children and their parents.

ReviewInterventions for ulceration and other skin changes caused by nerve damage in leprosy.
At the end of 2016, 145 countries reported to the World Health Organization (WHO) over 173,000 new cases of leprosy worldwide. In the past 20 years, over 16 million people have been treated for leprosy globally. The condition's main complications are injuries and ulceration caused by sensory loss from nerve damage. In this review we explored interventions to prevent or treat secondary damage to the skin in people affected by leprosy (Hansen's disease). This is an update of a Cochrane Review published in 2008. ⋯ Based on the available evidence, we could not draw firm conclusions about the effects of the included interventions. The main evidence limitations were high or unclear risk of bias, including selection, performance, detection, and attrition bias; imprecision due to few participants in the studies; and indirectness from poor outcome measurement and inapplicable interventions. Future research should clearly report important outcomes, such as adverse events, and assess widely available interventions, which should include treatments aimed at prevention. These trials should ensure allocation concealment, blinding, and an adequate sample size.

Motivational Interviewing (MI) is a directive patient-centred style of counselling, designed to help people to explore and resolve ambivalence about behaviour change. It was developed as a treatment for alcohol abuse, but may help people to a make a successful attempt to stop smoking. ⋯ There is insufficient evidence to show whether or not MI helps people to stop smoking compared with no intervention, as an addition to other types of behavioural support for smoking cessation, or compared with other types of behavioural support for smoking cessation. It is also unclear whether more intensive MI is more effective than less intensive MI. All estimates of treatment effect were of low certainty because of concerns about bias in the trials, imprecision and inconsistency. Consequently, future trials are likely to change these conclusions. There is almost no evidence on whether MI for smoking cessation improves mental well-being.
